Hey everyone! As many of you have already seen, @trogus and I are happy to announce the release of devRant++, also know as the devRant supporter program!
devRant++ is a monthly subscription ($1.99 USD) that gives you some cool extra features while also contributing to covering some of our ever-increasing server costs.
Subscribers get:
- a badge that shows up on all of their rants and comments
- ability to edit rants and comments for up to 30 minutes (instead of the usual 5)
- ability to post unlimited collabs for free (so keep an eye out for new collabs, hopefully!)
- a reserved spot on the devRant++ supporter list (you can only move up higher or stay in the same position through the life of your subscription)
- more benefits coming soon!
Why did devRant++ come to be? Basically, we have the most awesome community members and we kept getting extremely generous requests from members asking how they could help devRant stay afloat. Instead of taking donations and not giving anything directly in return, we wanted to give supporters a little extra something to hopefully make the program kind of special.
We greatly appreciate everyone who has joined the supporter program so far. We also realize not everyone has the money to spend or wants to spend, and that's perfectly fine. We also greatly appreciate everyone here who posts great rants and comments, helps spread the word about devRant, votes on stuff, or is just a valuable member of the community in general. @trogus and I value all contributions and we want to make that clear!
Another reason we decided to go ahead with the program is, as I mentioned towards the beginning, our server/technology costs are increasing and we're kind of at a point where we can't afford all of the upgrades we'd like to make. At the same time while we need more hardware, we're trying to get the app to a place where we're not losing money every month, hopefully to the point where we can break even soon.
Anyway, thank you to everyone again for the amazing support and early interest in devRant++. We would love to hear feedback and stuff you would like to see added to supporter benefits, so just let us know!60 -

I'm In Canada. A woke HR lady hires an African guy despite him plagiarizing code and lying through an interview. First day he surfs soccer websites so I confront it and HR lady basically calls me a racist and to watch my back.
A second African new-hire comes into the office today and he seems quite capable in an area of specialization for our team. So I ask if we can have him on our team because he has skills. The exec decides to look at the costing for him and goes, "HOLY SHIT WHY ARE WE PAYING ANYONE THAT MUCH?" She looks at the résumé of the new guy and finds out that he is only at intermediate level in his specialization. So I say, "It could be worse. The other guy flat out lied through his interview and he got hired anyway." I forward the emails where I recommended against hiring the other guy and why.
My exec, who is a company stakeholder, opens the pricing list for recent hires. It is obvious that if you are not not white you get paid way above market value for your skill level. Exec is pissed off on a level I never knew was possible.
We make a call from the board room only to find out that the head of HR (also an executive) is driving this. My exec tells me to give her the room. The yelling was so loud everyone could hear what was said from outside the boardroom. At one point the HR lady says, "Just because we could get them cheaper doesn't mean that we should… We pay that much because it is 'the right thing to do'." My executive goes completely silent for a few seconds then in a super aggressive way says.
"…I am going to have your FUCKING head for this. Then I will make sure that you NEVER get a job in HR again for the rest of my natural life. ONLY ONE of us will survive this. YOU are the one pissing away profit. So get ready because I'm going to drown you and your team like a bag full of unwanted puppies." Then she hung up the Polycom. She came out about a minute later and kicked the office manager out of his office and sat there all day making calls and sending emails.

A former colleague made an online shopping app. Boss wanted to promote him to Senior Developer when he still working with us.
14 days ago another colleague checked the code and told the boss that it's ready for production. No one asked me because everyone in the company thinks am the stupid developer of them all.
So what happened?
Well the total value of the cart was being over to payment gateway using a hidden field. Well you know the rest of the story.
The client has sued our company for this issue and boss came running to me and asked me to check if it was our fault or something else.
I checked and found the hidden value where the total value of cart was being stored and send over to payment gateway. The following is the conversation between me and the colleague who checked the code:
Me: So you checked the code and everything was okay?
Him: Yes, all good.
Me: Did you see this hidden field where the total value of cart is being passed to the payment gateway?
Him: Yes
Me: Why didn't you fix this?
Him: What's there to fix?
Me: Well someone can temper the value and let it pass to the payment gateway.
Him: No, they can't we are using https
Me: I' am done with you
He has Masters in software engineering and has few security certificates.25 -
I tutor people who want to program, I don't ask anything for it, money wise, if they use my house as a learning space I may ask them to bring cookies or a pizza or something but on the whole I do it to help others learn who want to.
Now this in of itself is perfectly fine, I don't get financially screwed over or anything, but...
Fuck me if some students are horrendous!
To the best of my knowledge I've agreed to work with and help seven individuals, four female three male.
One male student never once began the study work and just repeatedly offered excuses and wanted to talk to me about how he'd screwed his life up. I mean that's unfortunate, but I'm not a people person, I don't really feel emotionally engaged with a relative stranger who quite openly admits they got addicted to porn and wasted two years furiously masturbating. Which is WAY more than I needed to know and made me more than a little uncomfortable. Ultimately lack of actually even starting the basic exercises I blocked him and stopped wasting my time.
The second dude I spoke to for exactly 48 hours before he wanted to smash my face in. Now, he was Indian (the geographical India not native American) and this is important, because he was a friend of a friend and I agreed to tutor however he was more interested in telling me how the Brits owed India reparations, which, being Scottish, I felt if anyone was owed reparations first, it's us, which he didn't take kindly too (something about the phrase "we've been fucked, longer and harder than you ever were and we don't demand reparations" didn't endear me any).
But again likewise, he wanted to talk about politics and proving he was a someone "I've been threatened in very real world ways, by some really bad people" didn't impress me, and I demonstrated my disinterest with "and I was set on fire once cos the college kids didn't like me".
He wouldn't practice, was constantly interested in bigging himself up, he was aggressive, confrontational and condescending, so I told him he was a dick, I wasn't interested in helping him and he can help himself. Last I heard he wasn't in the country anymore.
The third guy... Absolute waste of time... We were in the same computer science college class, I went to university and did more, he dossed around and a few years later went into design and found he wanted to program and got in touch. He completes the code schools courses and understandably doesn't quite know what to do next, so he asks a few questions and declares he wants to learn full stack web development. Quickly. I say it isn't easy especially if it's your first real project but if one is determined, it isn't impossible.
This guy was 30 and wanted to retire at 35 and so time was of the essence. I'm up for the challenge, and so because he only knows JavaScript (including prototypes, callbacks and events) I tell him about nodejs and explain that it's a little more tricky but it does mean he can learn all the basis without learning another language.
About six months of sporadic development where I send him exercises and quizzes to try, more often than not he'd answer with "I don't know" after me repeatedly saying "if you don't know, type the program out and study what it does then try to see why!".
The excuses became predicable, couldn't study, playing soccer, couldn't study watching bake off, couldn't study, couldn't study.
Eventually he buys a book on the mean stack and I agree to go through it chapter by chapter with him, and on one particular chapter where I'm trying to help him, he keeps interrupting with "so could I apply for this job?" "What about this job?" And it's getting frustrating cos I'm trying to hold my code and his in my head and come up with a real world analogy to explain a concept and he finally interrupts with "would your company take me on?"
I'm done.
"Do you want the honest unabridged truth?"
"Yes, I'd really like to know what I need to do!"
"You are learning JavaScript, and trying to also learn computer science techniques and terms all at the same time. Frankly, to the industry, you know nothing. A C developer with a PHD was interviewed and upon leaving the office was made a laughing stock of because he seemed to not know the difference between pass by value and pass by reference. You'd be laughed right out the building because as of right now, you know nothing. You don't. Now how you respond to this critique is your choice, you can either admit what I'm saying is true and put some fucking effort into studying cos I'm putting more effort into teaching than you are studying, or you can take what I'm saying as a full on attack, give up and think of me as the bad guy. Your choice, if you are ready to really study, you can text me in the morning for now I'm going to bed."
The next day I got a text "I was thinking about what you said and... I think I'm not going to bother with this full stack stuff it's just too hard, thought you should know."23 -
At the airport.
Security: Please put all your electronics in the bin, including your watch.
Me: No problem
<goes through scanner>
Me: there was an Apple Watch in here and now it is gone.
Security: Oh, you lost your Apple Watch?
Me: No! I put my Apple Watch in the bin like you instructed and YOU lost my Apple Watch.
Security: It must be in the spinners.
Me: So my $500 Watch is in the spinners being run over by bins?
Security: you have to put the small things on the bottom.
Me: It was on the bottom and I did as you asked, this is entirely on you. Do not try to shift the blame to me again please.
Security: As I said...
Me: As I said, Do not try to shift the blame to me again. This is entirely your responsibility once you separate me from my electronics so you can perform security theatre. Have a nice day.
—————
Fuck this god damn security theatre. Fuck the dumbasses they hire. Fuck your country. Fuck your god damn feeling of insecurity. Fuck Your ineffective security theatre.
Sick my fucking dick until you choke and gag you worthless pieces of shit. Homeless people the street provide more security than you incompetent, under-educated assholes. Fuck you
And yes, I have 2 fucking laptops. I have a real fucking job where I provide actual value and for that I need a work laptop. I don’t come to work in a stupid looking outfit with a chip on my shoulder looking to inconvenience people. I come to work to provide real value to someone.
Fuck you and your worthless bullshit39 -
"Coding is solving puzzles".
I think everyone has heard that platitude. But it's not exactly right.
So I grew up in a very poor environment, a moldy building full of jobless addicts.
And in my town there was this shop where super poor parents could take their kids to borrow free toys and stuff.
So as a kid I remember being frustrated by these second hand jigsaw puzzles, because there were always a few pieces which had been teared up or chewed on, or were even completely missing.
That is what development is.
You pull in this seemingly awesome composer package, and that one super useful method is declared private, so you need to fork the whole thing.
Your coworker has built this great microservice in python, but instead of returning 404 not found, it returns 200 with json key/value saying "error": "not found".
There's a shitload of nicely designed templates for the company website, but half of them have container divs inside the components, the other half expect to be wrapped in container divs when included.
You're solving puzzles, but your peers are all brainless jigsaw-piece-chewers. They tried to mend a problem, but half way through got distracted, hungry and angry, started drooling over the task and used a hammer to fit in the remaining stuff.11 -

Programming is a huge blessing i believe we all should be thankful to. For me, it literally turned my life around.
11 months ago i was fighting a losing battle with depression, and contemplated suicide constantly. I would use a self remedy of smoking weed and sleeping all day long. I was depressed because i felt my life had no real value. I was doing nothing, and its kind of an infinite loop.
You don't do anything, so you feel bad, so you don't do anything, and so on.
That was until i finally took the step that changed my life. I searched and wanted to learn something. I always liked web pages so i thought id get into web development.
Did some research, found out that the fastest way to go was to learn ruby on rails. I followed a tutorial i found online, and literally pushed myself through it. There were times when there where things i didnt understand, and when it was really bad, but i pushed myself through it and i finished the tutorial.
Just finishing the tutorial and learning something new helped me alot. I had already quit smoking and was feeling way better, but after a while i started feeling bad again since i wasnt doing anything after i had finished learning, so i started working on a personal project, creating it from scratch, and just working on it day and night. I worked 14 hours a day, never really leaving my room ( this was during summer vacation ) for a month.
There were many things i didnt understand, but i never gave up and always searched for the solution and read about it until i understood it better. Looking back, there were things i knew could have been done in a better way, but as a first project, im proud of myself, not because it rocks, but because i did not give up.
In the process of starting a new life, i was really lonely. I cut all ties with everyone i knew, since they were all toxic, all i had in my life was ruby on rails and my web application. I wanted to launch it but couldn't due to personal reasons.
Not being able to launch and see something live, something that you worked so hard on, that you put so much effort into, that was devastating to me. I felt as if all my efforts had gone to waste.
And here is what i love most about programming, NOTHING EVER GOES TO WASTE. All that effort you spent on something ? All these all nighters you pulled ? All that frustration from that bug ? It will pay off later. It always does somehow. You get more knowledge and become a better programmer, and sometimes it even gives way to new opportunities and chances you never even expected.
I included my web application in my resume and it helped land me a job as a junior developer in a really nice company. A job that i wouldn't even have dreamed of several months earlier.
Programming and creating something new and learning something new everyday, creating something that people use, that someone else will benefit from and be grateful for, i think we should never take that for granted !
Tl;dr : learning how to code and web development saved my life9 -
I have to let it out. It's been brewing for years now.
Why does MySQL still exist?
Really, WHY?!
It was lousy as hell 8 years ago, and since then it hasn't changed one bit. Why do people use it?
First off, it doesn't conform to standards, allowing you to aggregate without explicitly grouping, in which case you get god knows what type of shit in there, and then everybody asks why the numbers are so weird.
Second... it's $(CURRENT_YEAR) for fucks sake! This is the time of large data sets and complex requirements from those data sets. Just an hour through SO will show you dozens of poor people trying to do with MySQL what MySQL just can't do because it's stupid.
Recursion? 4 lines in any other large RDBMS, and tough luck in MySQL. So what next? Are you supposed to use Lemograph alongside MySQL just because you don't know that PostgreSQL is free and super fast?
Window functions to mix rows and do neat stuff? Naaah, who the hell needs that, right? Who needs to find the products ordered by the customer with the biggest order anyway? Oh you need that actually? Well you should write 3-4 queries, nest them in an incredibly fucked up way, summon a demon and feed it the first menstrual blood of your virgin daughter.
There used to be some excuses in the past "but but but, shared hosting only has MySQL". Which was wrong by the way. This was true only for big hosting names, and for people who didn't bother searching for alternatives. And now it's even better, since VPS and PaaS solutions are now available at prices lower than shared hosting, which give you better speed, performance and stability than shared hosting ever did.
"But but but Wordpress uses MySQL" - well then kill it! There are other platforms out there, that aren't just outrageously horrible on the inside and outside. Wordpress is crap, and work on it pays crap. Learn Laravel, Symfony, Zend, or even Drupal. You'll be able to create much more value than those shitty Wordpress sites that nobody ever visits or pay money on.
"But but but my client wants some static pages presented beside their online shop" - so why use Wordpress then? Static pages are static pages. Whip up a basic MVC set-up in literally any framework out there, avoid MySQL, include a basic ACL package for that framework, create a controller where you add a CKEditor to edit page content, and stick a nice template from themeforest for that page and be done with that shit! Save the mock-up for later use if you do that stuff often. Or if you're lazy to even do that, then take up Drupal.
But sure, this is going a bit over the scope. I actually don't care where you insert content for your few pages. It can be a JSON file for all I care. But if I catch you doing an e-commerce solution, or anything else than just text storage, on MySQL, I'll literally start re-assessing your ability to think rationally.11 -
Learning soft skills.
I'm about as direct with coworkers and managers as I am on devRant. And I still think being painfully direct is often better than playing the heavily politicized office game of thrones.
But sometimes it's better to say:
"CTO, I think we need your skills to build bridges to other departments and manage recruitment. You're the only one who understands both technology and people, so drop your developer role and become our ambassador"
Instead of:
"Dear CTO, your code makes my eyes bleed. Your CS degree was a fucking waste of tax money, and it's quite clear that cheap college beer washed out all of your reasoning skills. We should fill the space you're taking up with a beanbag chair, because you're providing negative value to the company. How many investor cocks did you have to deep throat to get where you are?"
Now, I just pick option one, smile politely, and tell him we need to increase department budget as indemnification for having to work with a retard like him. Uh I mean... "to get developer salaries up to a competitive level so we can retain knowledge"10 -
Try not to use floating point numbers in places where precision is important. Like for instance, money. Always store the base value where it makes the most sense15

To all the design pattern nazis..
Don't you ever tell me that something is impossible because it violates some design pattern! Those design principles are there to make your life easier, not something you have to obey by law.
Don't get me wrong, you should where ever possible respect those best practices, because it keeps your software maintainable.
But your software should foremost solve real world problems and real world problems can be far more complex than any design pattern could address. So there are cases where you can consciously decide to disregard a best practice in order to provide value to the world.
Thanks for reading if you got this far.6 -
DevRant rant:
I am on DevRant for quite a while now and I really enjoy it here. The overall atmosphere is great, as well as the community. (Yes, that includes you!)
Since I came here I've learned some very valuable lessons regarding work (conditions), annoying coworkers and programming itself. I like to think of DevRant as a huge ball of experience by very talented people, as well as a great place for discussions about a topic we all love: code. But lately I am seeing more and more memes on here, with titles like "I think everybody know this", "I think everybody can relate" and "Soo true". Those posts have no value at all and are (most of the time) reposted from 9gag or similar networks. Sometimes those "rants" don't even have anything to do with devs anymore, but are only here to farm ++'es. In the beginning I really enjoyed funny "rants", but now the majority of them just annoy me. It becomes especially annoying when you see the same meme three times in 15 minutes.
I'd be in for some kind of DevFun section, where everybody is able to post his or hers jokes/memes/etc, but the current situation just really gets on my nerves.
I hope that I am not the only one who thinks like that, because I really feel uncomfortable ranting about something I actually love.

Me: Hi Guys, theres no docs on our custom push notification / deeplinking implementation. I've tried to work backwards from a QA testing doc to add new links. Can someone tell me if this is all ok? It seems to behave a little weird.
Dev: Looks ok, but we've moved to the braze platform for sending notifications. You'll need to trigger braze notifications now. Test that it works ok with that <confluence-link>
*hour later*
Me: I've tried the debugging tool, both with my payload and one of the samples from the link. It displays on the phone, but tapping it doesn't trigger the deeplinking.
Dev: No it works, try one of these <screenshot of samples I used>
*hour later*
Me: Tried it again on the real device to make sure, as well as on develop and master. Not working with those samples or mine.
Dev: No it does. It comes in here in this library <github link to line of code>
Me: ... Nope, debugged it, it doesn't get passed the next 'if' check on the next line as its missing a key/value. The whole function does nothing.
Dev: Oh do you want to send a braze notification?
Me: ..... you told me I had too .... yes I guess.
Dev: ok for a braze notification it works different, send this <entirely different sample no where on the link>
Me: ...... but ..... this is only for braze notifications ..... why .... all the samples have deeplink url's .... but they don't ....... are you ..... FFS!!!!! !@#?!

I had to open the desktop app to write this because I could never write a rant this long on the app.
This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.
Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.
[START RANT]
"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."
From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table
The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.
The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:
array[index]
Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.
Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:
a = {1, 5, 9};
a["hello_world"] = "whatever";
a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.
This is the difference between indexing and lookups. But you may say,
"Algo! If I do this:
a = {"first", "second", "third"};
print(a[1]);
...then "first" appears in my console!"
Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:
Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):
el = arr + (sz * i)
This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.
That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.13 -
Prologue
My dad has an acquaintance - let's call him Tom. Tom is an gynecologist, one of the best in Poznań, where I live. He's a great guy but absolutely can not into tech of any kind besides his iPhone and basic PC usage. For about a year now I've been doing small jobs for him - build a new PC for his office, fix printer, fix wifi, etc. He has made a big mistake few years ago by trusting a guy, let's call him Shitface, with crating him software for work. It's supposed to be pretty simple piece of code in which you can create and modify patient file, create prescription from drugs database and such things. This program is probably one of the worst pierces of code I've ever seen and Shitface should burn for that. Worse, this guy is pretentious asshole lacking even basic IT knowledge. His code is garbage and it's taking him few months to make small changes like text wrapping. But wait, there's more. Everything is hardcoded so every PC using this software must have installed user controls for which he doesn't have license and static IP address on network card.
Part 1
Tom asked me to build him a new PC that will be acting like a server for Shitface's program. He needs it in Kalisz (around 150 km from my place). I Agred (pun intended) and after Tom brought me his old computer I've bought parts and built a new one. I have also copied everything of value and everything took me around three hours.
Part 2
Everything was ready but Shitface's program. I didn't know much about it's configuration so when I've noticed that it's not working even on the old PC I got a bit worried. Nevertheless I started breaking everything I know about it and after next three hours I've got it somewhat working. Seeing that there's still some problems with database connection (from Windows' Event Viewer) I wrote quick SMS to Shitface asking what can be wrong. He replied that he won't be able to help me any way until Monday (day after deadline). I got pissed and very courteously asked him for source code because some of libraries used in this project has license that requires either purchase of commercial license or making code open source. He replied within few minutes that he'll be able to connect remotely within next 10 minutes. He was trying to make it work for the next hour but he succeeded. It was night before deadline so I wrapped everything up and went to bed thinking that it won't take me more than an hour to get this new PC up and running in the office. Boy was I wrong.
Also, curious about his code, I've checked source and he is using beautiful ponglish (mixed Polish and English) with mistakes he couldn't even bother to fix. For people from Poland, here's an example:
TerminarzeController.DeleteTerminarzShematyDlaLekarza
Part 3
So I drove to Kalisz and started working on making everything work. Almost everything was ready so after half an hour I was done. But I wanted to check twice if it's all good because driving so far second time would be a pain. So I started up Shitface's program, logged in, tried to open ANYTHING and... KABUM. UNHANDLED EXCEPTION. WTF. I checked trace and for fuck sake something was missing. Keep in mind that then I didn't know he's using some third party control for Windows Forms that needs to be installed on client PC. After next fifteen minutes of googling I've found a solution. I just had to install this third party software and everything will work. But... It had to be exactly this version and it was old. Very old. So old that producent already removed all traces of its existence from their web page and I couldn't find it anywhere. I tried installing never version and copying files from old PC but it didn't work. After few hours of searching for a solution I called Mr Shitface asking him for this control installation file. He told me that he has it but will be able to send it my way in the evening. Resigned I asked for this new PC to be left turned on and drove home. When he sent me necessary files I remotely installed them and everything started working correctly.
So, to sum it up. Searching for parts and building new PC, installing OS and all necessary software, updating everything and configuring it for Tom taste took me around what, 1/3 of time I spent on installing Mr Shitface's stupid program which Tom is not even happy with. Gotta say it was one of worst experiences I had in recent months. Hope I won't have to see this shit again.
Epilogue
Fortunately everything seems to work correctly. Tom hasn't called me yet with any problems. Mission accomplished. I wanna kill very specific someone. With. A. Spoon.1 -
VueJS FTW!
Today I realised I've been a fucking idiot.
For the last few years I have familiarized myself with libraries like React, VueJS, Preact etc.
All while playing around on my own side projects but when it came to doing actual work (perhaps from a lack of confidence/working experience with them) I always reverted to vanilla js or jQuery because I convinced myself it wasn't the `right` use case or `the project was too simple or small`.
I WAS AN IDIOT.
The below screenshot is a prototype of a n invoicing tool I needed to write which uses VueJS and is implemented in 50 beautiful, clean, maintainable loc. Combined with TypeScript it is a dream - never did I think I would see the day where I could grab an inputs numerical value without prepending the variable with + so I don't end up concatenating them as strings.
If your like me and haven't started using some kind of data binding view framework stop procrastinating and just do it. I feel like I wasted a large chunk of my life clinging onto my old ways.7 -

"4096 bit ~ 96 hours is what he said.
IDK why, but when he took the challenge, he posted that it'd take 36 hours"
As @cbsa wrote, and nitwhiz wrote "but the statement was that op's i3 did it in 11 hours. So there must be a result already, which can be verified?"
I added time because I was in the middle of a port involving ArbFloat so I could get arbitrary precision. I had a crude desmos graph doing projections on what I'd already factored in order to get an idea of how long it'd take to do larger
bit lengths
@p100sch speculated on the walked back time, and overstating the rig capabilities. Instead I spent a lot of time trying to get it 'just-so'.
Worse, because I had to resort to "Decimal" in python (and am currently experimenting with the same in Julia), both of which are immutable types, the GC was taking > 25% of the cpu time.
Performancewise, the numbers I cited in the actual thread, as of this time:
largest product factored was 32bit, 1855526741 * 2163967087, took 1116.111s in python.
Julia build used a slightly different method, & managed to factor a 27 bit number, 103147223 * 88789957 in 20.9s,
but this wasn't typical.
What surprised me was the variability. One bit length could take 100s or a couple thousand seconds even, and a product that was 1-2 bits longer could return a result in under a minute, sometimes in seconds.
This started cropping up, ironically, right after I posted the thread, whats a man to do?
So I started trying a bunch of things, some of which worked. Shameless as I am, I accepted the challenge. Things weren't perfect but it was going well enough. At that point I hadn't slept in 30~ hours so when I thought I had it I let it run and went to bed. 5 AM comes, I check the program. Still calculating, and way overshot. Fuuuuuuccc...
So here we are now and it's say to safe the worlds not gonna burn if I explain it seeing as it doesn't work, or at least only some of the time.
Others people, much smarter than me, mentioned it may be a means of finding more secure pairs, and maybe so, I'm not familiar enough to know.
For everyone that followed, commented, those who contributed, even the doubters who kept a sanity check on this without whom this would have been an even bigger embarassement, and the people with their pins and tactical dots, thanks.
So here it is.
A few assumptions first.
Assuming p = the product,
a = some prime,
b = another prime,
and r = a/b (where a is smaller than b)
w = 1/sqrt(p)
(also experimented with w = 1/sqrt(p)*2 but I kept overshooting my a very small margin)
x = a/p
y = b/p
1. for every two numbers, there is a ratio (r) that you can search for among the decimals, starting at 1.0, counting down. You can use this to find the original factors e.x. p*r=n, p/n=m (assuming the product has only two factors), instead of having to do a sieve.
2. You don't need the first number you find to be the precise value of a factor (we're doing floating point math), a large subset of decimal values for the value of a or b will naturally 'fall' into the value of a (or b) + some fractional number, which is lost. Some of you will object, "But if thats wrong, your result will be wrong!" but hear me out.
3. You round for the first factor 'found', and from there, you take the result and do p/a to get b. If 'a' is actually a factor of p, then mod(b, 1) == 0, and then naturally, a*b SHOULD equal p.
If not, you throw out both numbers, rinse and repeat.
Now I knew this this could be faster. Realized the finer the representation, the less important the fractional digits further right in the number were, it was just a matter of how much precision I could AFFORD to lose and still get an accurate result for r*p=a.
Fast forward, lot of experimentation, was hitting a lot of worst case time complexities, where the most significant digits had a bunch of zeroes in front of them so starting at 1.0 was a no go in many situations. Started looking and realized
I didn't NEED the ratio of a/b, I just needed the ratio of a to p.
Intuitively it made sense, but starting at 1.0 was blowing up the calculation time, and this made it so much worse.
I realized if I could start at r=1/sqrt(p) instead, and that because of certain properties, the fractional result of this, r, would ALWAYS be 1. close to one of the factors fractional value of n/p, and 2. it looked like it was guaranteed that r=1/sqrt(p) would ALWAYS be less than at least one of the primes, putting a bound on worst case.
The final result in executable pseudo code (python lol) looks something like the above variables plus
while w >= 0.0:
if (p / round(w*p)) % 1 == 0:
x = round(w*p)
y = p / round(w*p)
if x*y == p:
print("factors found!")
print(x)
print(y)
break
w = w + i
Still working but if anyone sees obvious problems I'd LOVE to hear about it.36 -
"Hey mate, how are you doing?"
*deep sigh* "It's tough, but I'm managing"
I don't think it's a coincidence that the word managing is often used as a synonym for "Technically alive, but not in a state where I can progress personally, or add any value to my environment".
Now imagine packaging that desolate self-perpetuating feeling of apathy into a farce, propped up with practiced smiles and meet-speak, and calling that daily routine a "career".11 -
Recruiters are fucking unbelievable sometimes.
With about one year experience I applied to company A and company B. Kinda competitors in what dev skillset they're looking for.
Company A reviewed my CV and decided I don't have enough experience without giving me a chance to present my actual knowledge.
Company B tells me screw your CV come along show us what you got. I rocked the interview with an offer the next day which I accepted, absolutely thrilled.
Fast forward 7 months I get an email from company A, same recruiter, inviting me to an interview as they're "impressed with my profile and feel like I've gone a long way" (definitely just because company B hired me and I passed my probation)
Ah the joy responding to them that as I value honour and honesty quite highly I don't think I would be a culture match for company B where it is a norm to reject candidates and come back pouch them after they pass probation at competitors.
Eek.. instant apologies email and of course explaining it's not poaching but "exploring opportunities".
Screw company A, honestly.5 -
So my in-laws got a new computer 😑
Yup you know where this is going. Ok so after I transferred all of their data set them all up etc.
They wanted to use "word" and could I set it up for free for them. I said no Microsoft office is not free you lost your license and disk and your old computer is trashed so the better choice would be Google services . So I explained the value of using Google drive, docs,sheets etc.. today and told them how much better it is everything would be on their Google drive so if I got hit by a bus they could get a new computer again and still have access to their data etc... So they said great and so I did.
Two weeks later... Can you set up word for us on our computer. Me annoyed at this point " sure no problem"
I made a shortcut on their desktop to Google docs. Them: oh boy this is great see John all you have to do is click on google docs to go to word! Thanks so much!

It was a normal school day. I was at the computer and I needed to print some stuff out. Now this computer is special, it's hooked up onto a different network for students that signed up to use them. How you get to use these computers is by signing up using their forms online.
Unfortunately, for me on that day I needed to print something out and the computer I was working on was not letting me sign in. I called IT real quick and they said I needed to renew my membership. They send me the form, and I quickly fill it out. I hit the submit button and I'm greeted by a single line error written in php.
Someone had forgotten to turn off the debug mode to the server.
Upon examination of the error message, it was a syntax error at line 29 in directory such and such. This directory, i thought to myself, I know where this is. I quickly started my ftp client and was able to find the actual file in the directory that the error mentioned. What I didn't know, was that I'd find a mountain of passwords inside their php files, because they were automating all of the authentications.
Curious as I was, I followed the link database that was in the php file. UfFortunately, someone in IT hadn't thought far enough to make the actual link unseeable. I was greeted by the full database. There was nothing of real value from what I could see. Mostly forms that had been filled out by students.
Not only this, but I was displeased with the bad passwords. These passwords were maybe of 5 characters long, super simple words and a couple number tacked onto the end.
That day, I sent in a ticket to IT and told them about the issue. They quickly remedied it by turning off debug mode on the servers. However, they never did shut down access to the database and the php files...2 -
Best part about the covid19 manufactured crisis?
Liquor stores deliver. Worst part about liquor stores delivering? Needing to use their shoddy websites.
I've been using a particular store (Total Wines) since they're cheaper than the rest and have better selection; it's quite literally a large warehouse made to look like a store.
Their website tries really hard to look professional, too, but it's just not. It took me two days to order, and not just from lack of time -- though from working 14 hour days, that's a factor.
Signing up was difficult. Your username is an email address, but you can't use comments because the server 500s, making the ajax call produce a wonderfully ambiguous error message. It also fades the page out like it's waiting on something, but that fade is on top of the error modal too. Similar error with the password field, though I don't remember how I triggered it.
Signing up also requires agreeing to subscribe to their newsletter. it's technically an opt-in, but not opting-in doesn't allow you to proceed. Same with opting-in to receiving a text notification when your order is ready for pickup -- you also opt-in to reciving SMS spam.
Another issue: After signing up, you start to navigate through the paginated product list. Every page change scrolls you to the exact middle of the next page. Not deliberatly; the UI loads first, and the browser gets as close as it can to your previous position -- which was below that as the pagination is at the bottom -- and then the products populate after. But regardless of why, there is no worse place to start because now you must scroll in both directions to view the products. If it stayed at the very bottom, it would at least mean you only need to scroll upwards to look at everything on the page. Minor, but increasingly irritating.
Also, they have like 198 pages of spirits alone because each size is unique entry. A 50ml, 350ml, 500ml, 750ml, 1000ml, and 1750ml bottle of e.g. Tito's vodka isn't one product, it's six. and they're sorted seemingly randomly. I think it's by available stock, looking back.
If you fancy a product, you can click on it for a detail page. Said detail page lists the various sizes in a dropdown, but they're not sorted correctly either, and changing sizes triggers a page reload, which leads to another problem:
if you navigate to more than a few pages within a 10 or so second window, the site accuses you of using browser automation. No captcha here, just a "click me for five seconds" button. However, it (usually) also triggers the check on every other tab you have open after its next nagivation.
That product page also randomly doesn't work. I haven't narrowed it down, but it will randomly decide to start failing, and won't stop failing for hours. It renders the page just fine, then immediately replaces it with a blank page. When it's failing, the only way to interact with the page is a perfectly-timed [esc], which can (and usually does) break all other page functionality, too. Absolutely great when you need to re-add everything from a stale copy of your signed-out cart living in another tab. More on that later. And don't forget to slow down to bypass the "browser automation" check, too!
Oh, and if you're using container tabs, make sure to open new tabs in the SAME container, as any request from the same IP without the login cookie will usually trigger that "browser automation" response, too.
The site also randomly signs you out, but allows you to continue amassing your cart. You'd think this is a good thing until you choose to sign in again... which empties your cart. It's like they don't want to make a sale at all.
The site also randomly forgets your name, replacing it with "null." My screen currently says "Hello, null". Hello, cruft!
It took me two days to order.
Mostly from lack of time, as i've been pulling 14 hour shifts lately trying to get everything done. but the sheer number of bugs certainly wasted most of what little time i had left. Now I definitely need a drink.
But maybe putting up with all of this is worthwhile because of their loyalty program? Apparently if you spend $500, you can take $5 off your next purchase! Yay! 1%! And your points expire! There are three levels; maybe it gets better. Level zero is for everyone; $0 requirement. There are also levels at $500 and $2500. That last one is seriously 5x more than the first paid level. and what does it earn you? A 'free' magazine subscription, 'free' classes (they're usually like $20-$50 iirc), and a 'free' grab bag (a $2.99 value!) twice per month. All for spending $2500. What a steal. It reminds me of Candy Crush's 3-star system where the first two stars are trivial, and the third is usually a difficult stretch goal. But here it's just thinly-veiled manipulation with no benefit.
I can tell they're employing some "smarketing" people with big ideas (read: stolen mistakes), but it's just such a fail.
The whole thing is a fail.8 -
An excerpt from the best rant about whiteboard interviews posted on the internet. Ever.
"Well, maybe your maximum subsequence problem is a truly shitty interview problem. You are putting your interview candidate in a situation where their employment hinges on a trivia question. — Kadane's algorithm! They know it, or they don't. If they do, then congratulations, you just met an engineer that recently studied Kadane's algorithm.
Which any other reasonably competent programmer could do by reading Wikipedia.
And if they don't, well, that just proves how smart the interviewer is. At which point the interviewer will be sure to tell you how many people couldn't answer his trivially simple interview question.
Find a spanning tree across a graph where the edges have minimal weight. Maybe one programmer in ten thousand — and I’m being generous — has ever implemented this algorithm in production code. There are only a few highly specific vertical fields in the industry that have a use for it. Despite the fact that next to no one uses it, the question must be asked during job interviews, and you must write production-quality code without looking it up, because surely you know Kruskal’s algorithm; it’s trivial.
Question: why are manhole covers round? Answer: they’re not just round, if you live in London; they're triangular and rectangular and a bunch of other shapes. Why is your interview question broken? Why did you just crib an interview question without researching whether its internal assumption was correct? Do you think that “round manhole covers are easier to roll" is a good answer? Have you ever tried to roll an iron coin that weighs up to 300 pounds? Did you survive? Do you think that “manhole covers are circular so that they don’t fall into manholes” is a good answer? Do you know what a curve of constant width is? Do you know what a Reuleaux triangle is? Have you ever even been to London?
If the purpose of interviewing was to play stump the candidate, I’d just ask you questions from my area of specialization. “What are the windowing conditions which, during the lapping operation on a modified discrete cosine transform, guarantee that the resynthesis achieves perfect reconstruction?” The answer of course is the Princen-Bradley condition! Everyone knows that’s when your windowing function satisfies the conditions h(k)2+h(k+N)2=1 (the lapping regions of the window, squared, should sum to one) and h(k)=h(2N−1−k) (the window should be symmetric). That’s fundamental computer science. So obvious, even a child should know the answer to that one. It’s trivial. You embarrass your entire extended family with your galactic stupidity, which is so vast that its value can only be stored in a double, because a float has insufficient range:"

I never had problems with punctuation marks during coding, especially the notorious semicolons because I've always used an IDE, ain't gotta time to waste on compiler errors.
But today I meet my nemesis, a fucking comma wasted an hour of my precious time, causing my unit tests to fail in Python, my unit tests where expecting a list and the actual value is a tuple, it turned out that there was this trailing comma - which I don't know where the hell it came from - at the end of a function call that returns a list.
I only noticed this freaking comma after Pycharm indicated a conflict between the returned type and the expected type and underlined the culprit, that small invisible fucker 😬.
Thank you Pycharm and type hints in Python 3.
this is why, my fellow devs, you have to use an IDE.
PS: For those of you who aren't familiar with python, a trailing comma at end of a variable turns it into a one element tuple.

Fuck brand builders, or, how I learned to start giving a shit and love devrant.
Brand builders are people who generally have very little experience and are attempting to obfuscate their dearth of ability behind a wall of non-academic content generation. Subscribe, like, build a following and everyone will happily overlook the fact that your primary contribution to society is spreading facile content that further obfuscates the need for fundamentals. Their carefully crafted presence is designed promote themselves and their success while chipping away at the apparent value of professional ability. At one point, I thought medium would be the bottom of the barrel; a glorified blog that provides people with scant knowledge, little experience and routinely low integrity a platform to build an echo chamber of replayed or copied content, techno-mysticism and best-practice-superstition they mistake for a brand in an environment where there's little chance of peer review. I thought it couldn't get any worse.
Then I found dev.to
Dev.to is what happens when all the absence of ability and skills insecurity on the internet gets together to form a censorship mob to ensure that no criticism, reality or peer review will ever filter into the ramblings of people intent on forever remaining at the peak of the dunning-kreuger curve. It's the long tail of YMCA trophy culture.
Take for example this article:
https://dev.to/davidepacilio/...
It's a shit post listicle by someone claiming to be "senior," who confidently states that "you are only as good as the tools you use." Meanwhile all the great minds of history are giving him the side-eye because they understand tools are just a magnifier of ability. If you're an amazing carpenter, power tools will help you produce at an exponential rate. If you're a shitty carpenter, your work will still be shit, there will just be more of it. The actual phrase that's being butchered here is "you're only as good as the tools you create." There's no moral superiority to be had in being dependent on a tool, that's just a crutch. A true expert or professional is someone who can create tools to aid in their craft. Being a professional is having a thorough enough understanding of the thing you are doing so as to be able to craft force multipliers that make your work easier, not just someone who uses them.
Ok, so what?
I'm sure he's a plenty fine human to grab drinks with, no ill will to him as a human. That said, were you to comment something to that effect on dev.to, you'd be reported by all the hangers-on pretty much immediately, regardless of how much complimentary padding and passive, welcoming language you wrap your message in. The problem with a bunch of weak people ganging up on the voice of reason and deciding they don't want things like constructive criticism, peer review, academic process or the scientific method is, after you remove all of that, you're just left with a formless sea of ideas and thoughts with no categorization, no order. You find a lot of opinions and nothing to challenge them and thereby are left with no mechanism for strong ideas to rise to the top. In that system, the "correct" ideas are by default those posited by the strongest personality.
We all need some degree of positive reinforcement. We also need to be smacked upside the head when we're totally off in the weeds. It's all about balance. The forums of ancient Greece weren't filled with people fervently agreeing with one another and shouting down new ideas en masse. We need discourse, not demagoguery.
Dev.to, medium, etc are all the fast fashion of the tech industry. Personally, I'd prefer something designed to last a little longer.30 -
Awkward recruiting process? Sit the fuck back!
So about a year ago I got laid off. I got some help setting up LinkedIn and realising I'm not trash and offers to talk started flowing in.
So this consultancy firm asks me to come in for a talk and having nothing better to do I oblige - they're working on big, exciting Greenfield stuff and I'm amazed they want me.
Fast forward the most nervous week in my life and the HR assistant brings me into the meeting room, I get some water and a nice first impression - also my last. I wait in the room for five minutes.
In walks madam HR, madam Team lead and miss assistant from before, all carrying big ass laptops. We shake hands and they sit down and all open up their laptops between me and them - I just sit there feeling naked with my block of paper and pencil I brought.
So we wait for their machines to start up and madam HR just starts throwing questions at me and seemingly noting my answers into a sheet. Meanwhile madam Teamlead is busy on her phone most of the time and my most human interaction remains smalltalk and questions between me and miss assistant.
I did manage to get madam Teamlead to look up from her phone when I asked how they felt about the fact that I have no formal training and would need to pick up a lot of skills as we go, to which she said something along 'well this ain't a candy shop, we expect you to work' and looked back down at her phone.
A bit shaken, I agreed to stay for the technical test (apparently I passed the interview...)
Now this test was designed by their CTO since he didn't feel like any of the available tests on the market could properly judge applicants' skilllevels. Yes, alarms went off already at that point.
What I'm presented with is a word document with questions, and another for answers and... It's just string gymnastics and reference/value difference knowledge - shit it takes you a split second to look up or test if you ever get into these insane cases where you need to know. And then there was a likewise one with sql statements that was also just convoluted query gymnastics and trying to hide changes in the seemingly same statement through various questions. No questions on design, no problem solving, just... Attention span testing with a dash of coding?
Anyway, it turned out they had evening and weekend shifts and round the clock support tournus which on top of the ridiculous recruitment process and way lower than average salary offer had me turn them down.
Don't enable bullshit people, run away!4 -
"I'm almost done, I'll just need to add tests!"
Booom! You did it, that was a nuke going off in my head.
No, you shouldn't just need to add tests. The tests should have been written from the get go! You most likely won't cover all the cases. You won't know if adding the tests will break your feature, as you had none, as you refactor your untested mess in order to make your code testable.
When reading your mess of a test case and the painful mocking process you went through, I silently cry out into the void: "Why oh why!? All of this suffering could have been avoided!"
Since most of the time, your mocking pain boils down to not understanding what your "unit" in your "unit test" should be.
So let it be said:
- If you want to build a parser for an XML file, then just write a function / class whose *only* purpose is: parse the XML file, return a value object. That's it. Nothing more, nothing less.
- If you want to build a parser for an XML file, it MUST NOT: download a zip, extract that zip, merge all those files to one big file, parse that big file, talk to some other random APIs as a side-effect, and then return a value object.
Because then you suddenly have to mock away a http service and deal with zip files in your test cases.
The http util of your programming language will most likely work. Your unzip library will most likely work. So just assume it working. There are valid use cases where you want to make sure you acutally send a request and get a response, yet I am talking unit test here only.
In the scope of a class, keep the public methods to a reasonable minimum. As for each public method you shall at least create one test case. If you ever have the feeling "I want to test that private method" replace that statement in your head with: "I should extract that functionality to a new class where that method public. I then can create a unit test case a for that." That new service then becomes a dependency in your current service. Problem solved.
Also, mocking away dependencies should a simple process. If your mocking process fills half the screen, your test setup is overly complicated and your class is doing too much.
That's why I currently dig functional programming so much. When you build pure functions without side effects, unit tests are easy to write. Yet you can apply pure functions to OOP as well (to a degree). Embrace immutability.
Sidenote:
It's really not helpful that a lot of developers don't understand the difference between unit, functional acceptance, integration testing. Then they wonder why they can't test something easily, write overly complex test cases, until someone points out to them: No, in the scope of unit tests, we don't need to test our persistance layer. We just assume that it works. We should only test our businsess logic. You know: "Assuming that I get that response from the database, I expect that to happen." You don't need a test db, make a real query against that, in order to test that. (That still is a valid thing to do. Yet not in the scope of unit tests.)rant developer unit test test testing fp oop writing tests get your shit together unit testing unit tests8 -
Frustrated, tired and a bit lost.
I'm a "Senior PHP Backend Dev", which includes not the greatest tech stack nor the best job title, but it pays fine, and the company is awesome to work for.
I suck at writing features, but I'm great at bitching, and I easily put complex abstract concepts into usable models. So I'm also QA, tester, tech lead, database architect, whatever.
That makes writing PHP less annoying, because I create the rules, and whip devs around when they forget a return type definition or forget to handle an edge case. But I don't write a lot of code anymore, I mostly read (bad) code.
Lately I REALLY feel like doing something else... problem is that I know JS/ES6, but really dislike React/Vue and the whole crappy modern frontend toolchainchootrain of babelifyingwebpackingyarnballs. I know Python/Tensorflow/etc, but don't feel like I want to go into data science or AI. And then I'm awesome at the shit no one uses, like Haskell, Go and Rust (and worse).
I got a job offer which combines a very interesting PHP codebase with a Java infrastructure, where I could learn a lot... and I'm kind of tempted.
Problem is, everyone always shits on Java. I always made a bit of fun of Java myself. Don't even know exactly why, probably some really cruel instinct which causes kids to bully the least popular kid.
I know the basics, I've written the hello world, and a small backend app for a personal project. I know how strict and verbose it can be. I love the strictness in Haskell and Rust.... but those are both also quite terse.
Should I become a Java dev? I'm not talking about Android SDK, but an insane enterprise codebase at a life sciences corporation.
To the pro Java devs: What are the best and worst things about your job, about the weekly processes, about the toolchains? Have you ever considered other languages? Do you unconditionally love and believe in Java, or do you believe Swift, Kotlin, Scala or whatever will eventually make it completely obsolete?
Will Java hasten my decline into the cynical neckbeard I was always destined to be?
There are a lot more fun langauges, but looking at realistic demand and career value...20 -
Everyone was a noob once. I am the first to tell that to everyone. But there are limits.
Where I work we got new colleagues, fresh from college, claims to have extensive knowledge about Ansible and knows his way around a Linux system.... Or so he claims.
I desperately need some automation reinforcements since the project requires a lot of work to be done.
I have given a half day training on how to develop, starting from ssh keys setup and local machine, the project directory layout, the components the designs, the scripts, everything...
I ask "Do you understand this?"
"Yes, I understand. " Was the reply.
I give a very simple task really. Just adapt get_url tasks in such a way that it accepts headers, of any kind.
It's literally a one line job.
A week passes by, today is "deadline".
Nothing works, guy confuses roles with playbooks, sets secrets in roles hardcodes, does not create inventory files for specifications, no playbooks, does everything on the testing machine itself, abuses SSH Keys from the Controller node.... It's a fucking ga-mess.
Clearly he does not understand at all what he is doing.
Today he comes "sorry but I cannot finish it"
"Why not?" I ask.
"I get this error" sends a fucking screenshot. I see the fucking disaster setup in one shot ...
"You totally have not done the things like I taught you. Where are your commits and what are.your branch names?"
"Euuuh I don't have any"

I get frustrated, but nonetheless I re-explain everything from too to bottom! I actually give him a working example of what he should do!
Me: "Do you understand now?"
Colleague: "Yes, I do understand now?"
Me: "Are you sure you understand now?"
C: "yes I do"
Proceeds to do fucking shit all...
WHY FUCKING LIE ABOUT THE THINGS YOU DONT UNDERSTAND??? WHAT KIND OF COGNITIVE MALFUNCTION IA HAPPENING IN YOUR HEAD THAT EVEN GIVEN A WORKING EXAMPLE YOU CANT REPLICATE???
WHY APPLY FOR A FUCKING JOB AND LIE ABOUT YOUR COMPETENCES WHEN YOU DO T EVEN GET THE FUCKING BASICS!?!?
WHY WASTE MY FUCKING TIME?!?!?!
Told my "dear team leader" (see previous rants) that it's not okay to lie about that, we desperately need capable people and he does not seem to be one of them.
"Sorry about that NeatNerdPrime but be patient, he is still a junior"
YOU FUCKING HIRED THAT PERSON WITH FULL KNOWLEDGE ABOUT HAI RESUME AND ACCEPTED HIS WORDS AT FACE VALUE WITHOUT EVEN A PROPER TECHNICAL TEST. YOU PROMISED HE WAS CAPABLE AND HE IS FUCKING NOT, FUCK YOU AND YOUR PEOPLE MANAGEMENT SKILLS, YOU ALREADY FAIL AT THE START.

Did some updates to an older Web Forms website built by a previous SENIOR developer who is a notoriously horrible developer.
Now before I start, you have to understand this guy studied at a University and had been working for at least two years before I even started working. He is supposed to know the basic shit mentioned below.
This also happened a couple of days ago, so I have calmed down since then so I apologise for the relaxed tone. My next rant will contain a lot more swearing.
This fucking guy did the stupidest shit imaginable.
On the details view of a post|page|article|product|anything that would require a details view this jackass would load the data from the DB.
Using an OleDbConnection, OleDbDataAdapter, DataTable and the poorest writter fucking sql statements you have ever seen. All of these declared in the Page_Load method.
There was literally no reason for him to use OleDb instead of Sql, but he simply did not know any better.
He especially liked: "select * from tbl where id = " & Request("T") & ""
ZERO fucking checks to see if the value is even passed or valid, nothing. He did not even check whether the DataTable had any rows.
He then proceeded to use only the Heading column of the returned row to change the page's title.
Stupidly I assumed the aspx page will be in a better state. Fuck NO!
This fucktard went, added server tags to the opening of the asp:Content tag, copied that shit he used to fetch the data and pasted it between the server tags.
He did not know how to access the DataTable mentioned above from the aspx page!
He did this on every fucking project he worked on. Any place that required <%= %> to display data instead of using asp server controls, this cunt copied whatever was written in the code behind and pasted everything between server tags.
Fuck I could go on forever, but I think this is enough for my first rant.2 -
fuck you, man. eat a bag of dicks, a bag of shit and a shit load of dead animals.. you dumb fucking cunt ... go and die ... who the fuck modifies state of 3rd party object and think it is ok to do so.. the fucking prick deserves to get castrated with rusty, old school, gardening scissors...
through some mysterious, obfuscated, buried deep in the asshole code, the fucker decided to set a user-specific value in the default query params of guzzle so that every fucking object using it passes the fucking thing around like a cheap hooker at a dorm party... causing the API calls to misbehave because of the fucking thing.
you send the parameters you want to send but mister sucking-dick-up-the-ass-smarty-pants decided you don't want to do that and because of that I almost broke a core library a week before a fucking major feature release because half the functionality got broken automagically, worst thing is I have no fucking clue where the bloody thing gets inserted ...
I swear if you do that I will find you and I will get a rusty razor to cut your balls into paste and rectally infuse them untill your shit start to come out of every oriphise of your fucking empty head8 -
OMFG I don't even know where to start..
Probably should start with last week (as this is the first time I had to deal with this problem directly)..
Also please note that all packages, procedure/function names, tables etc have fictional names, so every similarity between this story and reality is just a coincidence!!
Here it goes..
Lat week we implemented a new feature for the customer on production, everything was working fine.. After a day or two, the customer notices the audit logs are not complete aka missing user_id or have the wrong user_id inserted.
Hm.. ok.. I check logs (disk + database).. WTF, parameters are being sent in as they should, meaning they are there, so no idea what is with the missing ids.
OK, logs look fine, but I notice user_id have some weird values (I already memorized most frequent users and their ids). So I go check what is happening in the code, as the procedures/functions are called ok.
Wow, boy was I surprised.. many many times..
In the code, we actually check for user in this apps db or in case of using SSO (which we were) in the main db schema..
The user gets returned & logged ok, but that is it. Used only for authentication. When sending stuff to the db to log, old user Id is used, meaning that ofc userid was missing or wrong.
Anyhow, I fix that crap, take care of some other audit logs, so that proper user id was sent in. Test locally, cool. Works. Update customer's test servers. Works. Cool..
I still notice something off.. even though I fixed the audit_dbtable_2, audit_dbtable_1 still doesn't show proper user ids.. This was last week. I left it as is, as I had more urgent tasks waiting for me..
Anyhow, now it came the time for this fuckup to be fixed. Ok, I think to myself I can do this with a bit more hacking, but it leaves the original database and all other apps as is, so they won't break.
I crate another pck for api alone copy the calls, add user_id as param and from that on, I call other standard functions like usual, just leave out the user_id I am now explicitly sending with every call.
Ok this might work.
I prepare package, add user_id param to the calls.. great, time to test this code and my knowledge..
I made changes for api to incude the current user id (+ log it in the disk logs + audit_dbtable_1), test it, and check db..
Disk logs fine, debugging fine (user_id has proper value) but audit_dbtable_1 still userid = 0.
WTF?! I go check the code, where I forgot to include user id.. noup, it's all there. OK, I go check the logging, maybe I fucked up some parameters on db level. Nope, user is there in the friggin description ON THE SAME FUCKING TABLE!!
Just not in the column user_id...
WTF..Ok, cig break to let me think..
I come back and check the original auditing procedure on the db.. It is usually used/called with null as the user id. OK, I have replaced those with actual user ids I sent in the procedures/functions. Recheck every call!! TWICE!! Great.. no fuckups. Let's test it again!
OFC nothing changes, value in the db is still 0. WTF?! HOW!?
So I open the auditing pck, to look the insides of that bloody procedure.. WHAT THE ACTUAL FUCK?!
Instead of logging the p_user_sth_sth that is sent to that procedure, it just inserts the variable declared in the main package..
WHAT THE ACTUAL FUCK?! Did the 'new guy' made changes to this because he couldn't figure out what is wrong?! Nope, not him. I asked the CEO if he knows anything.. Noup.. I checked all customers dbs (different customers).. ALL HAD THIS HARDOCED IN!!! FORM THE FREAKING YEAR 2016!!! O.o
Unfuckin believable.. How did this ever work?!
Looks like at the begining, someone tried to implement this, but gave up mid implementation.. Decided it is enough to log current user id into BLABLA variable on some pck..
Which might have been ok 10+ years ago, but not today, not when you use connection pooling.. FFS!!
So yeah, I found easter eggs from years ago.. Almost went crazy when trying to figure out where I fucked this up. It was such a plan, simple, straight-forward solution to auditing..
If only the original procedure was working as it should.. bloddy hell!!8 -
Fucking Amazon rant again...
TLDR: Amazon specializes in “the last mile”. They are repeatedly allowing a 3rd party shipper (Purolator) destroy their main value proposition. Thoughts at the end.
Me on the phone with their support...
Me: so it says my package was attempted to be delivered today. I did not get a call or notification or anything and I have been working from home all day to wait for the package.
Support: -Sigh- yes, I can see it was Purolator we have been having trouble with them lately.
Me: ok, so are you able to see what happened?
Support: let me put you on hold.
.......
Support: So they said they will not call for a delivery, did they use your building buzzer?
Me: Nope, just stood outside the building and then left I guess.
Support: -sigh- Well you can pick it up at their depot. Let me get you the address.
Me: The one by the airport?
Support: Yes it looks like it is about an hour away from where you are. And they are only open during work hours.
Me: So, after working from home to get this package you advice is to take 3 hours off work and go there to pick it up?
Support: Well, we can refund it? If thats what you want.
Me: No, I would like the package I ordered please.
Support: There is nothing I can do sir.
Me: So before I hang up let me see if I have it straight. When I order a package from Amazon, do I have an option of who ships it?
Support: No, I’m sorry but that is decided on our end.
Me: And I have had this problem before with this shipping agent. So, your telling me that when I ship things to me with Amazon that I have no control of wether I even get the package? Your telling me it is literally a coin toss as to wether or not I ever get my package?
Support: yes sir, I’m sorry but that is all I can do.
Me: So you realize that, for example, if I went to my local grocery store and it was a coin toss that I could take my groceries home (even after I paid for them) then I will always go to another store....
Support: yes, I know. There is nothing I can do.
Me: So from now on I have to order items, wait for them to be shipped, check the shipper and then cancel the order of it is them?
Support: -sigh- you cannot cancel an order after it has shipped...
Me: wow. Sure is great being a prime and audible member. I get fast delivery of 50% of my packages and no delivery at all of the other 50%. Sorry for the sarcasm...
Support: I’m sorry I can’t help more.
Me: So just to clarify. I can expect NOT to get the package I ordered?
Support: sorry
Me: have a nice day.
————
Here are my thoughts as a student of business...
Amazon specializes in “the last mile” (in their delivery service anyway) and when they deliver the package they also deliver on that value proposition.
However, now it seems that one of their shipping providers is failing at getting packages that last mile, which is resulting and destroying the idea of their value proposition in a customers eyes. (Affecting more than me as the rep said)
Now, instead of believing that Amazon will get things to me, saving me that last mile trip to the store etc., I firmly believe that it is a toss up as to wether I will ever receive my package (based on carrier)
I know that if I was in Amazon’s position (a carrier hurting my overall value proposition with consistently unacceptable service) that I would come down on them with a force they have never seen or drop them entirely.
But of course, every company reaches a point where they have such market share and sway that they take their eye off the ball when it comes to their value proposition to customers.16 -
TL;DR you suck, I suck and everybody sucks, deal with it....
------------------------------------
Let me let off some steam, since I've had enough of people hating on languages "just because"
Every language has it's drawbacks and quirks, BUT they have their strengths also. Saying "I hate {language}" is just you being and ignorant prick and probably your head is so far up your ass that you look like an ass hat. With that being said, every language is either good or bad depending on the developer writing in it. Let's give you an example:
If I ware to give you a brick and ask you to put a nail in a plank, can you do it? Yes, it will be easier if you do it with a hammer, but you have a brick, so hammer is out of the question. If you hit your thumb while doing it... well... sorry, but it is not the bricks fault - it is YOU!
JavaScript, yes it has a whole lot of problems, but it works, you can do a ton of stuff and does a good job at that, it is evolving through node and typescript (and others, just a personal pref), BUT if you used js when you ware debugging that jquery (1.0) plugin written in the free time of a 13 yo, who copy pasted a bunch from SO, well, it is not js' problem - deal with it. Same goes for PHP, i've been there where you had a single `index.php` with bazillion lines of code, did a bunch of eval and it was called MVC, but it also is evolving.. thing is all languages allow you to do some dumb stuff so YOU have to be responsible to not fuck it up (which you always DO btw, we all do). Difference is PHP/JS roll with it because the assumption is that you know what you are doing, which again - newsflash - you don't.
More or less I would blame that shit on businesses which decided to go with undergrads to save money instead of investing in their product, hell, I am in a major company that does not invest that doesn't care a whole lot about dev /tech stuff and now everybody's mother is an engineer - they care about money, because investors care about money (ROI) and because clean code does not pay the bills, but money does.
If we get all of the good practices and apply them to each language every one of them has it's place, that is why there is no "The Language", even if there was, we STILL ware going to fuck it up and probably it was going to be even worse than where we are now.
Study, improve, rinse and repeat... There are SENIORS and LEADS out there that are about 25-30 and have no fucking clue about the language, because they have stuck up their heads up the ass of frameworks and refuse to take a breath of clean air and consider something different than their dogmatic framework "way" of doing things.. That is the result you are seeing. Let me give you a fresh example to illustrate where I am at atm:
Le me works with ZendFramework 2.3-2.5 (why not, which is PHP5+ running on PHP7 [fancy, eh]), and little me writes a module for said project, and tries to contain it in its own space, i.e not touching anything outside of the folder of the module so it is SELF-CONTAINED (see, practices), during 2-3-4 iterations of code review, I've had to modify 4 different modules with `if (somthing === self::SOMETHING_TYPE)` as requested by my TL, which resulted in me not covering 3 use-cases after the changes and not adding a new event (the fw is event-driven, cuz.. reasons) so I have to use a bunch of ifs in the code, to check a config value and do shit. That is the way of I am asked to do things I hate what I've done and the fact that because of CR I have lost case-coverage, a week of work and the same TL will be on my ass on monday that things are now "perfect".
The biggest things is "we care about convention and code style"... right.... That is not because of the language, not because of me, not because of the framework - it is some dude's opinion that you hate, not the language.
New stuff are better, reinventing the wheel is also good, if it wasn't you would've had a few stone circular things on your car and things ware going to be like that - we need to try and try, that is the only way we actually learn shit.
Until things change in the trade, we will be on the same boat, complaining about the same shit over and over, you and me won't be alive probably but things will not change a bit.
We live in a place where state is considered good, god objects necessary (can you believe it, I've got kudos for using the term 'God Object'... yep, let that sink in). If you really hate something, please, oh god I beg you, show me how you will do it better and I will shake your hand and buy you a beer, but until then, please keep your ass-hurt fanboy opinion to your self, no one gives a shit about what you think, we will die and the world will not notice...6 -
I work in a contract position and reviewed the code of a senior engineer recently. Regretfully I can't provide context to preserve anonymity.
He wrote awful JavaScript;
- handled a single DOM element with 2 different frontend libraries
- used the logical operator && to 'chain' two methods (it didn't work) instead of returning a boolean value,
- broke everything down into minute detail (a comment box had 7 components!),
- API calls were made for every component update instead of maintaining local component state where it made sense, which meant UI updates were slow,
- animated EVERYTHING, which made my Firefox on Xubuntu i7 64bit with 16GB RAM beg for mercy.
I had a rough couple of months with interviews, with 2nd stage technical interviewers throwing impossible tasks at me.
Example:
1. Create an online Python code editor with Javascript which can compile Python bytecode,
2. Use Mesos and Kafka to create real time architecture for Tensorflow with a Javascript frontend in 1 day. (I asked, and wasn't allowed to use Kubernetes or serverless architecture),
3. Hack a website from the browser's address bar using parameters ( what?!! ),
Obviously, the next time I meet a 'senior', I'm going to tell him talk is cheap;
'SHOW ME YOUR CODE.'3 -
Rant. (I love and respect all people! Especially developers.)
You frontend imbecils! I just can’t deal with you any more. I’ve had it.
Stop-inventing-new-components-where-there-are-fully-developed-and-working-concepts!
I mean. Just fucking stop! If I see another worthless datetime picker with an ”innovative” design I am going to hunt you down and freaking scream in your face.
And make fucking buttons look like tappable/clickable. It’s not fucking hard! Imbecils.
Oh, ooo, look at me, I am a frontend developer and I am in UX la-la land and what I am doing is sooo hard. Fuck off with your fucking moving gradients and n:th-child childish playground.
”Yeah, I exchanged the spinner…”
Fuck you. Your not contributing. Nobody cares! We’re not doing anything for the business by having a web which can be seen on a fucking telephone. EVERYBODY IS SITTING WITH SEVERAL GIANT MONITORS AND A FUCKING WORKSTATION FOR THIS. NOBODY ASKED FOR IT. AND YOU SPEND COUNTLESS HOURS ON IT.
”Yeah, I made the site work on ipad”
Please. Why? It’s not worth anything. Zero value.
”Yeah, the toggle component is now changed since we started to use the biddle-flipflup lib and it works almost the same”
No! NO! It does not work ”almost” the same. The psychology of the toggle is now wastly different. What was On before now looks like Off and it is fucking worse!!!
Imbecils. I hate you.
And no, I can’t do your fucking work! And I know that you do other non-ui stuff as well sometimes… but anyway… I have no interest to be in that clusterfuck that modern frontend is today. It was really fucking bad twenty years ago and it is just as bad today and you are not helping.
”I’ve improved the button so now it aaaaalmost does not look like a button. But I am getting there!”
Fuck you.14 -
I think I just blew my own mind here.
Look at this:
Class SomeClass
{
_call($functionName, $arguments)
{
return call_user_func(array('SomeClass','uselessMethod'), 'method');
}
method($foo)
{
return new Adapter($foo)->execute($this);
}
uselessMethod()
{
return $this->method(__FUNCTION__);
}
}
so __FUNCTION__ resolves to
Caller:
You can run that code, whether you comment out uselessMethod, or not.
Adapter is a function that looks for what class to call depending on a database value
and execute the call.
So api basically uses a chain call to do stuff like this in controllers, here's how
I call the above:
$someObject = (new Class($object))->uselessMethod()->doSomething()->doSomethingElse();
But like, eventually my code matured to where all those methods in the chain call have the same one line return that calls my adapter to find the logic to run.
So, basically, I can now have a class with headless function calls that calls a directory of other classes, that are all defined in a contract somewhere. So as long as those classes
all adhere to the contract, it will never return an error.
I can't think of any reason to do this, other than my setup, and I have a sneaky feeling,
as dirty as this trick is, that there's a bad reason my code has come to being able to do this.
Maybe wrong strategy pattern from the beginning?
I'm sure it'll come to me like 3 days from now..3 -
Today on "How the Fuck is Python a Real Language?": Lambda functions and other dumb Python syntax.
Lambda functions are generally passed as callbacks, e.g. "myFunc(a, b, lambda c, d: c + d)". Note that the comma between c and d is somehow on a completely different level than the comma between a and b, even though they're both within the same brackets, because instead of using something like, say, universally agreed-upon grouping symbols to visually group the lambda function arguments together, Python groups them using a reserved keyword on one end, and two little dots on the other end. Like yeah, that's easy to notice among 10 other variable and argument names. But Python couldn't really do any better, because "myFunc(a, b, (c, d): c + d)" would be even less readable and prone to typos given how fucked up Python's use of brackets already is.
And while I'm on the topic of dumb Python syntax, let's look at the switch, um, match statements. For a long time, people behind Python argued that a bunch of elif statements with the same fucking conditions (e.g. x == 1, x == 2, x == 3, ...) are more readable than a standard switch statement, but then in Python 3.10 (released only 1 year ago), they finally came to their senses and added match and case keywords to implement pattern matching. Except they managed to fuck up yet again; instead of a normal "default:" statement, the default statement is denoted by "case _:". Because somehow, everywhere else in the code _ behaves as a normal variable name, but in match statement it instead means "ignore the value in this place". For example, "match myVar:" and "case [first, *rest]:" will behave exactly like "[first, *rest] = myVar" as long as myVar is a list with one or more elements, but "case [_, *rest]:" won't assign the first element from the list to anything, even though "[_, *rest] = myVar" will assign it to _. Because fuck consistency, that's why.
And why the fuck is there no fallthrough? Wouldn't it make perfect sense to write
case ('rgb', r, g, b):
case ('argb', _, r, g, b):
case ('rgba', r, g, b, _):
case ('bgr', b, g, r):
case ('abgr', _, b, g, r):
case ('bgra', b, g, r, _):
and then, you know, handle r, g, and b values in the same fucking block of code? Pretty sure that would be more readable than having to write "handeRGB(r, g, b)" 6 fucking times depending on the input format. Oh, and never mind that Python already has a "break" keyword.
Speaking of the "break" keyword, if you try to use it outside of a loop, you get an error "'break' outside loop". However, there's also the "continue" keyword, and if you try to use it outside of a loop, you get an error "'continue' not properly in loop". Why the fuck are there two completely different error messages for that? Does it mean there exists some weird improper syntax to use "continue" inside of a loop? Or is it just another inconsistent Python bullshit where until Python 3.8 you couldn't use "continue" inside the "finally:" block (but you could always use "break", even though it does essentially the same thing, just branching to a different point).19 -
The saying "Perfect is the enemy of done" is so much BS.
The war on perfection is the enemy of artistic expression.
Look at old world architecture vs modern crap. Crafts are no longer a thing but stuff is only made as effeciently as it can be for the greedy and impatient.
The artists and craftsmen of old knew well that perfect was achievable and constantly strove to be more and more perfect in their arts and by side effect on themselves. In this mad world we've lost that to the pragmatists who see no value in the art of perfection or in those who do not value those who do.
The "doneists" can go fuck themselves. Perfectionism is where true artistic expression is at.14 -
I really don't get all the Musk fans. I mean, sure you can find some value in Tesla or SpaceX, sure you can think theses companies are truly innovating. But why give all the credit to the rich businessman who seems to spent more time promoting himself than really working on science stuff, and not to all the ingeneers and creatives who are really putting some hard work on every day ? All Musk is really doing is running a business. He seems to do that pretty well, agreed, but after all it's "just" that: business. He's not the genius, nor the creative. He has money and invests it well, that's all.
I don't get why so many people give all the credit to him, even here on devrant where it should be logical to find more people supporting the real brains behind the tech.
"He has a vision about the future, he's imaginative..."
- Well that's bullshit.
Once again: he has money, a lot, and a certain skill about how to invest it (and about doing some proper marketing too), which companies to buy, etc. That don't make him such a great visionary about the future of the human being, just a great businessman. I'm sure you can find millions of people around the world with better ideas about the future, but they're not in his position. They're not rich, they're not CEOs, they're mostly unknown.
Stop follow the stream by glorifying businessmen just because medias are talking lot about them. Instead, know where the real talent (and work) is. Give credit to Musk employees, not to him.54 -
Just had a scolding from an asshole behind the wheel for using my old BuzzyPazz instead of their new electronic system. I didn't go with the invitation earlier because I don't want a central server to know where I am, and when. Yet that mofo is gonna threaten me with sanctions because I value my privacy, and even showed that I'm a legitimate passenger that's properly paid to get on the fucking bus?! Catch the right "criminals", motherfucker!!! 😤1

Two big moments today:
1. Holy hell, how did I ever get on without a proper debugger? Was debugging some old code by eye (following along and keeping track mentally, of what the variables should be and what each step did). That didn't work because the code isn't intuitive. Tried the print() method, old reliable as it were. Kinda worked but didn't give me enough fine-grain control.
Bit the bullet and installed Wing IDE for python. And bam, it hit me. How did I ever live without step-through, and breakpoints before now?
2. Remember that non-sieve prime generator I wrote a while back? (well maybe some of you do). The one that generated quasi lucas carmichael (QLC) numbers? Well thats what I managed to debug. I figured out why it wasn't working. Last time I released it, I included two core methods, genprimes() and nextPrime(). The first generates a list of primes accurately, up to some n, and only needs a small handful of QLC numbers filtered out after the fact (because the set of primes generated and the set of QLC numbers overlap. Well I think they call it an embedding, as in QLC is included in the series generated by genprimes, but not the converse, but I digress).
nextPrime() was supposed to take any arbitrary n above zero, and accurately return the nearest prime number above the argument. But for some reason when it started, it would return 2,3,5,6...but genprimes() would work fine for some reason.
So genprimes loops over an index, i, and tests it for primality. It begins by entering the loop, and doing "result = gffi(i)".
This calls into something a function that runs four tests on the argument passed to it. I won't go into detail here about what those are because I don't even remember how I came up with them (I'll make a separate post when the code is fully fixed).
If the number fails any of these tests then gffi would just return the value of i that was passed to it, unaltered. Otherwise, if it did pass all of them, it would return i+1.
And once back in genPrimes() we would check if the variable 'result' was greater than the loop index. And if it was, then it was either prime (comparatively plentiful) or a QLC number (comparatively rare)--these two types and no others.
nextPrime() was only taking n, and didn't have this index to compare to, so the prior steps in genprimes were acting as a filter that nextPrime() didn't have, while internally gffi() was returning not only primes, and QLCs, but also plenty of composite numbers.
Now *why* that last step in genPrimes() was filtering out all the composites, idk.
But now that I understand whats going on I can fix it and hypothetically it should be possible to enter a positive n of any size, and without additional primality checks (such as is done with sieves, where you have to check off multiples of n), get the nearest prime numbers. Of course I'm not familiar enough with prime number generation to know if thats an achievement or worthwhile mentioning, so if anyone *is* familiar, and how something like that holds up compared to other linear generators (O(n)?), I'd be interested to hear about it.
I also am working on filtering out the intersection of the sets (QLC numbers), which I'm pretty sure I figured out how to incorporate into the prime generator itself.
I also think it may be possible to generator primes even faster, using the carmichael numbers or related set--or even derive a function that maps one set of upper-and-lower bounds around a semiprime, and map those same bounds to carmichael numbers that act as the upper and lower bound numbers on the factors of a semiprime.
Meanwhile I'm also looking into testing the prime generator on a larger set of numbers (to make sure it doesn't fail at large values of n) and so I'm looking for more computing power if anyone has it on hand, or is willing to test it at sufficiently large bit lengths (512, 1024, etc).
Lastly, the earlier work I posted (linked below), I realized could be applied with ECM to greatly reduce the smallest factor of a large number.
If ECM, being one of the best methods available, only handles 50-60 digit numbers, & your factors are 70+ digits, then being able to transform your semiprime product into another product tree thats non-semiprime, with factors that ARE in range of ECM, and which *does* contain either of the original factors, means products that *were not* formally factorable by ECM, *could* be now.
That wouldn't have been possible though withput enormous help from many others such as hitko who took the time to explain the solution was a form of modular exponentiation, Fast-Nop who contributed on other threads, Voxera who did as well, and support from Scor in particular, and many others.
Thank you all. And more to come.

Ok here's the story,
There is this girl older than me by 5-7years and I worked with her for 2 years in the past...
She's fun to be around, and lights the mood in the workplace...
However one day I found her CV in my machine so I went through it. (It's no crime and it was there in my machine idk y)
And as I went through the list of projects, I was surprised and taken back to see she listed one of my solo project which I managed and developed from scratch as if she contributed to it. 🤯
The management specifically handed me the whole project and I singlehandedly carried it out and finished it and that was one of the projects I was super proud of and elaborated in my interviews.😎
But since she was sitting beside me and she knew basic requirement and the solutions I developed she had the knowledge on the project.
I was bewildered to see she has mentioned that project in her CV which she had zero contribution. I didn't feel like confronting her thinking when someone asks full details on the projects she would have to lie in the interviews cz she wouldn't know much details on it. And hey not everyone has my ethics and lets see how far she goes with hers.(may be this was stupid but I just thought hey we go our own ways lets see how far you go with lies and I forgot about it completly)
But now she's trying to apply to my current workplace where I dreamed of joining and finally succeeded and happy, here they value trustworthyness and quality work ethics above anything else... and without even telling me she has added me as a reference person to get more points to get an internal recommendation.
I certainly don't want to put a good word on her work ethics. Her team spirit and everything is fine but I just CANNOT with correct conscience ignore her bad ethics and recommend her.
What should I do? I don't want to loose her as a friend but I will not and do not want to recommend her to any place knowing she cannot be trusted with work related stuff. I know if I just tell the truth to the company when they ask she will definitely will not be chosen and I might feel guilty knowing I stopped it from happening.... but I don't want to recommend her truly knowing her bad qualities which in my openion cannot be overlooked also.
Should I just overlook it and help, or should I just tell the truth to the company... errgggh10 -

I used to read.. A lot. Long and complicated stories, where the plot would only unveil itself after a long time. I used to dig myself into a book, learning about the writer's thoughts and mental image, reflecting on our differing viewpoints on the question at hand. I didn't expect action or beauty, merely thoughts which, by themselves, constitued a value to me.
But pulp and especially social media had lowered my attention span to the point that even reading through a short story without getting sidetracked takes a lot of effort. I still value what I used to value, the only thing that's changed is that I no longer have the patience and I feel discomfort due to the lack of sensations.
What do I do? Had anyone solved this problem before?4 -
My boss has been begging me migrate a nightmarish complex excel report he made to calculate the payout of a tiered rebates program with compounding rewards. Today I finally decided to make take the time and I sat down with him so he could break it down for me...
Me: *looking at the mess of formula's* it would be easier to rewrite the math than decode this - can you just give me the reward rules... where does that value in cellX come from?
Him:*pointing at the spreadsheet* There! All the rules are in there for you :-)... like it's some big favour...
Me:No I mean when you wrote this, what did you base this off? There must be something...
Him: *Very Gravely* No, no, no it's far to complex! It took me ages to get this sheet right and it balances so just trust me and use it ok?
At this point I will mention he's an accountant so yeah I fucking trust him... fast forward past 15 minutes of digging through what may as well be quantum theory and lo and fucking behold all 2 sheets and 100 calculations are mathematically fucking pointless. Aside from formulas like this:
$X10=+(((O10+P10)-((O10+P10)*$X$3))*$R$4)+T10
which is actually equal to (X10/R4)/L10.
Anyway once you compound and sum the "tiered" benefits the rewards payout is ALWAYS = customerSpend*1.81.
This is why programmers name variables. -
The ones who use it, what do you like or value about Linux? Why do you use it?
Before I answer, let me say that I am a noob compared to the rest of this community. I run Ubuntu because Arch was too complicated when I tried and bash scripts equal to frustrations for me. That's my knowledge level.
- I don't feel "observed" when using a Linux distro compared to Windows and macOS.
- Feel more connected to the open source thought and the free spirit.
- Feel like I can do anything I want. Learning new programming languages easily, trying out web servers, try and setup own website or mail server etc.
- Everything is accessible. Read something cool about docker? ALT+T to open a terminal and start up a docker container to try out.
- No Internet browsing for software, like googling "Firefox download english".
- Sometimes forces me to learn about the workings of a computer, like networks, servers, routing, firewalls, bootup sequence etc.
- So many great command line tools. Want to find out quickly who owns a website? Want to query a specific DNS server? All possible within 5 seconds!
All in all using Linux feels like watching a documentary while using Windows is more like watching a dumb comedy show where I can turn my brain off, but get more stupid after a while.6 -
So im a programming student at university, tasked with a small group project to make a simple 3d platformer in ue4.
End up with 3 games design students where I'm doing all of the technical stuff while they do sound, graphics and design.
So I make a simpe all purpose ai that can do everything they need and hand it over. The next day I get a call saying it doesn't work. Takes me an hour to realise they don't have a navmesh. Now, that wasn't too unreasonable mistake as they didn't know what one was but a few hours later they call me again saying it doesn't deal any damage.
I'm going through the blueprints and can't find out what isn't working until an idea pops into my head.
Me "Click the damage variable for me"
Them "What's a variable?"
Me "That thing on the bottom left that says damage. Then the world value should pop up on the right with a number, tell me that number."
Them "0"
So apparently they fucked with the variable and set damage dealt to 0. Dunno why, they didn't even know what it was nor what it did.
This is my life at the moment. I hope a real job ain't this bad :(1 -
I've been a programmer for almost 19 years but I actually think the best code I've ever written is something that while it provides value to other people I'm the only one who actually uses it. In the company where I work we have major events that have to be supported by a number of different teams across about 5 time zones and each engineer has a limited set of roles that they can perform during the event. Anyway it was painful just watching people trying to create a schedule so I wrote something with Linear Programming to automatically generate the schedule. It ensures that people don't work for longer than 4 hours in a row, don't work from more than 8 hours from the first hour to the last hour on call, get 12 hours rest between engagements and the work load is evenly distributed across the team. Creating conditions in Linear Programming is weird, imagine trying to turn a series of linear equations into boolean logic, it can be done and once you can wrap your head around it it's really fun. It was my first time writing anything in it and I don't see it coming up a lot in my career. My favourite part of this project is that the end result was that engineers were less exhausted. I really hope that doesn't remain the best code I ever wrote, I don't think it will but it will require a conscious intention.2

So here's my problem. I've been employed at my current company for the last 12 months (next week is my 1 year anniversary) and I've never been as miserable in a development job as this.
I feel so upset and depressed about working in this company that getting out of bed and into the car to come here is soul draining. I used to spend hours in the evenings studying ways to improve my code, and was insanely passionate about the product, but all of this has been exterminated due to the following reasons.
Here's my problems with this place:
1 - Come May 2019 I'm relocating to Edinburgh, Scotland and my current workplace would not allow remote working despite working here for the past year in an office on my own with little interaction with anyone else in the company.
2 - There is zero professionalism in terms of work here, with there being no testing, no planning, no market research of ideas for revenue generation – nothing. This makes life incredibly stressful. This has led to countless situations where product A was expected, but product B was delivered (which then failed to generate revenue) as well as a huge amount of development time being wasted.
3 - I can’t work in a business that lives paycheck to paycheck. I’ve never been somewhere where the salary payment had to be delayed due to someone not paying us on time. My last paycheck was 4 days late.
4 - The management style is far too aggressive and emotion driven for me to be able to express my opinions without some sort of backlash.
5 - My opinions are usually completely smashed down and ignored, and no apology is offered when it turns out that they’re 100% correct in the coming months.
6 - I am due a substantial pay rise due to the increase of my skills, increase of experience, and the time of being in the company, and I think if the business cannot afford to pay £8 per month for email signatures, then I know it cannot afford to give me a pay rise.
7 - Despite having continuously delivered successful web development projects/tasks which have increased revenue, I never receive any form of thanks or recognition. It makes me feel like I am not cared about in this business in the slightest.
8 - The business fails to see potential and growth of its employees, and instead criticises based on past behaviour. 'Josh' (fake name) is a fine example of this. He was always slated by 'Tom' and 'Jerry' as being worthless, and lazy. I trained him in 2 weeks to perform some basic web development tasks using HTML, CSS, Git and SCSS, and he immediately saw his value outside of this company and left achieving a 5k pay rise during. He now works in an environment where he is constantly challenged and has reviews with his line manager monthly to praise him on his excellent work and diverse set of skills. This is not rocket science. This is how you keep employees motivated and happy.
9 - People in the business with the least or zero technical understanding or experience seem to be endlessly defining technical deadlines. This will always result in things going wrong. Before our mobile app development agency agreed on the user stories, they spent DAYS going through the specification with their developers to ensure they’re not going to over promise and under deliver.
10 - The fact that the concept of ‘stealing data’ from someone else’s website by scraping it daily for the information is not something this company is afraid to do, only further bolsters the fact that I do not want to work in such an unethical, pathetic organisation.
11 - I've been told that the MD of the company heard me on the phone to an agency (as a developer, I get calls almost every week), and that if I do it again, that the MD apparently said he would dock my pay for the time that I’m on the phone. Are you serious?! In what world is it okay for the MD of a company to threaten to punish their employees for thinking about leaving?! Why not make an attempt at nurturing them and trying to find out why they’re upset, and try to retain the talent.
Now... I REALLY want to leave immediately. Hand my notice in and fly off. I'll have 4 weeks notice to find a new role, and I'll be on garden leave effective immediately, but it's scary knowing that I may not find a role.
My situation is difficult as I can't start a new role unless it's remote or a local short term contract because my moving situation in May, and as a Junior to Mid Level developer, this isn't the easiest thing to do on the planet.
I've got a few interviews lined up (one of which was a final interview which I completed on Friday) but its still scary knowing that I may not find a new role within 4 weeks.
Advice? Thoughts? Criticisms?
Love you DevRant <33 -
so I left uni after my PhD and joined a start up where the boss is a Cambridge grad who does coding and is like 50 years old (he never told us the true value), the CTO is very talented and another dev who quickly became my best friend and me doing data science. the 4 of us worked together like friends and the efficiency was fantastic, there's no bureaucracy bullshit or shit boss talks. We built the whole thing from scratch (okay I admit they did most of the building) and to this day, we work just has we have been.
-
I'm feeling like writing this down...
So today I got told off by my boss. Why? Because my job bores me.
My current title, "webmaster", is quite similar to "plumber" where I work. I fix holes on our websites, and I tell "qualified" people (external providers) how a project should be made. Nothing exciting, nothing creative, boring.
So I got told off today for being "laid-back" in a newsletter project (GDPR, looking at you) and not being thorough in my procedures of testing and configuration. Fair enough, I didn't care and I admitted it. It's a boring drag-and-drop done in literally 5 minutes, there's no added brain-value here. Plus I got told off by my IT Manager because our Exchange server would not let me receive test emails. Still doesn't work after a day. Yay.
Then she said "we're doing exciting things here, it's not always the case anywhere else you'd work". And I'm like: "really? I love writing code, seeing things coming alive, investigating why things don't run smoothly, writing efficient code (both in performance and in readability)". I hear many friend devs telling me they're doing that and what they do during their "dev-day"... All I'm doing here is "maintenance" (a.k.a boring) stuff that apparently is "exciting". Adding a <script> to handle google tag manager is hell fun, going through compiled CSS and change color values is also thrilling, finding out if a PDF handler application can handle PDF files, re-plugging a computer monitor to make it work...
I think she meant that I'm not at my place here.
Didn't want to tell her that I have no motivation in doing things I don't enjoy making, i.e, my job.
Good thing I have an interview in two weeks2 -
Most painful code error you've made?
More than I probably care to count.
One in particular where I was asked to integrate our code and converted the wrong value..ex
The correct code was supposed to be ...
var serviceBusMessage = new Message() {ID = dto.InvoiceId ...}
but I wrote ..
var serviceBusMessage = new Message() {ID = dto.OrderId ...}
At the time of the message bus event, the dto.OrderId is zero (it's set after a successful credit card transaction in another process)
Because of a 'true up' job that occurs at EOD, the issue went unnoticed for weeks. One day the credit card system went down and thousands of invoices needed to be re-processed, but seemed to be 'stuck', and 'John' was tasked to investigate, found the issue, and traced back to the code changes.
John: "There is a bug in the event bus, looks like you used the wrong key and all the keys are zero."
Me: "Oh crap, I made that change weeks ago. No one noticed?"
John: "Nah, its not a big deal. The true-up job cleans up anything we missed and in the rare event the credit card system goes down, like now. No worries, I can fix the data and the code."
<about an hour later I'm called into a meeting>
Mgr1: "We're following up on the credit card outage earlier. You made the code changes that prevented the cards from reprocessing?"
Me: "Yes, it was my screw up."
Mgr1: "Why wasn't there a code review? It should have caught this mistake."
Mgr2: "All code that is deployed is reviewed. 'Tom' performed the review."
Mgr1: "Tom, why didn't you catch that mistake."
Tom: "I don't know, that code is over 5 years old written by someone else. I assumed it was correct."
Mgr1: "Aren't there unit tests? Integration tests?"
Tom: "Oh yea, and passed them all. In the scenario, the original developers probably never thought the wrong ID would be passed."
Mgr1: "What are you going to do so this never happens again?"
Tom: "Its an easy addition to the tests. Should only take 5 minutes."
Mgr1: "No, what are *you* going to do so this never happens again?"
Me: "It was my mistake, I need to do a better job in paying attention. I knew what value was supposed to passed, but I screwed up."
Mgr2: "No harm no foul. We didn't lose any money and no customer was negativity affected. Credit card system may go down once, or twice a year? Nothing to lose sleep over. Thanks guys."
A week later Mgr1 fires Tom.
I feel/felt like a total d-bag.
Talking to 'John' later about it, turns out Tom's attention to detail and 'passion' was lacking in other areas. Understandable since he has 2 kids + one with special-needs, and in the middle of a divorce, taking most/all of his vacation+sick time (which 'Mgr1' dislikes people taking more than a few days off, that's another story) and 'Mgr1' didn't like Tom's lack of work ethic (felt he needed to leave his problems at home). The outage and the 'lack of due diligence' was the last straw.1 -
When I was in college OOP was emerging. A lot of the professors were against teaching it as the core. Some younger professors were adamant about it, and also Java fanatics. So after the bell rang, they'd sometimes teach people that wanted to learn it. I stayed after and the professor said that object oriented programming treated things like reality.
My first thought to this was hold up, modeling reality is hard and complicated, why would you want to add that to your programming that's utter madness.
Then he started with a ball example and how some balls in reality are blue, and they can have a bounce action we can express with a method.
My first thought was that this seems a very niche example. It has very little to do with any problems I have yet solved and I felt thinking about it this way would complicate my programs rather than make them simpler.
I looked around the at remnants of my classmates and saw several sitting forward, their eyes lit up and I felt like I was in a cult meeting where the head is trying to make everyone enamored of their personality. Except he wasn't selling himself, he was selling an idea.
I patiently waited it out, wanting there to be something of value in the after the bell lesson. Something I could use to better my own programming ability. It never came.
This same professor would tell us all to read and buy gang of four it would change our lives. It was an expensive hard cover book with a ribbon attached for a bookmark. It was made to look important. I didn't have much money in college but I gave it a shot I bought the book. I remember wrinkling my nose often, reading at it. Feeling like I was still being sold something. But where was the proof. It was all an argument from authority and I didn't think the argument was very good.
I left college thinking the whole thing was silly and would surely go away with time. And then it grew, and grew. It started to be impossible to avoid it. So I'd just use it when I had to and that became more and more often.
I began to doubt myself. Perhaps I was wrong, surely all these people using and loving this paradigm could not be wrong. I took on a 3 year project to dive deep into OOP later in my career. I was already intimately aware of OOP having to have done so much of it. But I caught up on all the latest ideas and practiced them for a the first year. I thought if OOP is so good I should be able to be more productive in years 2 and 3.
It was the most miserable I had ever been as a programmer. Everything took forever to do. There was boilerplate code everywhere. You didn't so much solve problems as stuff abstract ideas that had nothing to do with the problem everywhere and THEN code the actual part of the code that does a task. Even though I was working with an interpreted language they had added a need to compile, for dependency injection. What's next taking the benefit of dynamic typing and forcing typing into it? Oh I see they managed to do that too. At this point why not just use C or C++. It's going to do everything you wanted if you add compiling and typing and do it way faster at run time.
I talked to the client extensively about everything. We both agreed the project was untenable. We moved everything over another 3 years. His business is doing better than ever before now by several metrics. And I can be productive again. My self doubt was over. OOP is a complicated mess that drags down the software industry, little better than snake oil and full of empty promises. Unfortunately it is all some people know.
Now there is a functional movement, a data oriented movement, and things are looking a little brighter. However, no one seems to care for procedural. Functional and procedural are not that different. Functional just tries to put more constraints on the developer. Data oriented is also a lot more sensible, and again pretty close to procedural a lot of the time. It's just odd to me this need to separate from procedural at all. Procedural was very honest. If you're a bad programmer you make bad code. If you're a good programmer you make good code. It seems a lot of this was meant to enforce bad programmers to make good code. I'll tell you what I think though. I think that has never worked. It's just hidden it away in some abstraction and made identifying it harder. Much like the code methodologies themselves do to the code.
Now I'm left with a choice, keep my own business going to work on what I love, shift gears and do what I hate for more money, or pivot careers entirely. I decided after all this to go into data science because what you all are doing to the software industry sickens me. And that's my story. It's one that makes a lot of people defensive or even passive aggressive, to those people I say, try more things. At least then you can be less defensive about your opinion.53 -
How bad it feels when it work in a place where Agile and DevOps are mostly abused buzzwords.
Forced doing "scrum" with:
- half of the team providing endless daily reports instead of focusing on the 3 questions
- a scrum master that is barely reachable
- a product owner that would not even make a decision
- a sponsor that pushes us to go faster regardless of current technical debt (it's important to look good to other sponsors!)
- doing all possible scrum ceremonies with no value added
- not even estimating stories
- not even having accurate description in stories. Most of the time not even a description.
- half of the team not understanding agile and DevOps at all
Feels so good (not). Am I the one in that boat?? ⁉️
What's the point of doing scrum if implemented that badly?? 😠6 -

Arduino CNC
Hey guys.
Since I mostly see frameworks to use with G-Code in Arduino CNCs I'm gonna make my own framework, where you don't need to know G-Code and the code is executed by Arduino code.
The code would include a template to define steppers steps and such.
Would include a library to work with different stepper shields.
Would this interest to anyone?
I'll provide a full example with stuff to learn for any amateur working with CNCs or that want to work with one. If you're not interested, thank you for reading, you can stop here.
Ex:
X(10);
Y(-5.5);
XY(6,7.5);
Z(-10);
This framework would only use incremental coordinates and will work for basic forms, drilling and such.
<Tutorial>
Coordinates.
Coordinates can be relative/incremental or absolute.
Lets say you have a square with 10mm, (top coordinates: (X=0,Y=0) to (X=10,Y=10).
think your drawing this square.
First line:
X0, Y0
Absolute: x10,y0
Relative: X+10
Second line:
A: x10,y10
R: Y+10
Third Line (...)
Absolute is a fixed point (coordinate)
Relative is a distance to move (not a coordinate but the distance and direction)
</Tutorial>
So, to cut a square with a TR10 (end mill with radius=5, diameter=10)
<code>
// You don't place + in positive values
// The tool always cut in the direction of the tool rotation, meaning on the left of the material.
Z(10); // Security Distance
XY(-5,0); //Compensate the diameter of the tool in radius
Z(-1); // Z=0 is the top of the block to mill, in this case. Z=0 can also be in the bottom
Y(15); //Second Point
X(15); // Third Point
Y(-15); // Forth point
X-15; // Fifth Point
(repeat)
</code>
Now we have a block with 1mm depth. If you use a while or for you can repeat the sequence for x=n passages, change the value to Z for the depth and your done.30 -

Use this as a template to send rejection letter to your recruiter as a revenge.
"Dear Recruiter,
Thank you for considering me for the software engineering position at your company. After careful consideration, I regret to inform you that I am unable to accept your offer.
As a highly qualified and skilled software engineer, I am confident that I could bring a great deal of value to your organization. However, after reading the job description and learning more about your company, I have come to the realization that I am simply too good for the position. I have no interest in joining a team where my talents and abilities would be underutilized and unappreciated.
Furthermore, I am a bit concerned about the working environment at your company. I have heard rumors that the office is dingy, the cafeteria food is subpar, and the company culture is lacking. I am a true perfectionist, and I refuse to settle for anything less than the best.
In conclusion, I must decline your offer. I wish you and your company the best of luck in finding a candidate who is worthy of the position.
Sincerely,
[Your Name]"4 -
dev, ~boring
This is either a shower thought or a sober weed thought, not really sure which, but I've given some serious consideration to "team composition" and "working condition" as a facet of employment, particularly in regard to how they translate into hiring decisions and team composition.
I've put together a number of teams over the years, and in almost every case I've had to abide by an assemblage of pre-defined contexts that dictated the terms of the team working arrangement:
1. a team structure dictated to me
2. a working temporality scheme dictated to me
3. a geographic region in which I was allowed to hire
4. a headcount, position tuple I was required to abide by
I've come to regard these structures as weaknesses. It's a bit like the project management triangle in which you choose 1-2 from a list of inadequate options. Sometimes this is grounded in business reality, but more often than not it's because the people surrounding the decisions thrive on risk mitigation frameworks that become trickle down failure as they impose themselves on all aspects of the business regardless of compatibility.
At the moment, I'm in another startup that I have significantly more control over and again have found my partners discussing the imposition of structure and framework around how, where, why, who and what work people do before contact with any action. My mind is screaming at me to pull the cord, as much as I hate the expression. This stems from a single thought:
"Hierarchy and structure should arise from an understanding of a problem domain"
As engineers we develop processes based on logic; it's our job, it's what we do. Logic operates on data derived from from experiments, so in the absence of the real we perform thought experiments that attempt to reveal some fundamental fact we can use to make a determination.
In this instance we can ask ourselves the question, "what works?" The question can have a number contexts: people, effort required, time, pay, need, skills, regulation, schedule. These things in isolation all have a relative importance ( a weight ), and they can relatively expose limits of mutual exclusivity (pay > budget, skills < need, schedule < (people * time/effort)). The pre-imposed frameworks in that light are just generic attempts to abstract away those concerns based on pre-existing knowledge. There's a chance they're fine, and just generally misunderstood or misapplied; there's also a chance they're insufficient in the face of change.
Fictional entities like the "A Team," comprise a group of humans whose skills are mutually compatible, and achieve synergy by random chance. Since real life doesn't work on movie/comic book logic, it's easy to dismiss the seed of possibility there, that an organic structure can naturally evolve to function beyond its basic parts due to a natural compatibility that wasn't necessarily statistically quantifiable (par-entropic).
I'm definitely not proposing that, nor do I subscribe to the 10x ninja founders are ideal theory. Moreso, this line of reasoning leads me to the thought that team composition can be grown organically based on an acceptance of a few observed truths about shipping products:
1. demand is constant
2. skills can either be bought or developed
3. the requirement for skills grows linearly
4. hierarchy limits the potential for flexibility
5. a team's technically proficiency over time should lead to a non-linear relationship relationship between headcount and growth
Given that, I can devise a heuristic, organic framework for growing a team:
- Don't impose reporting structure before it has value (you don't have to flatten a hierarchy that doesn't exist)
- crush silos before they arise
- Identify needed skills based on objectives
- base salary projections on need, not available capital
- Hire to fill skills gap, be open to training since you have to pay for it either way
- Timelines should always account for skills gap and training efforts
- Assume churn will happen based on team dynamics
- Where someone is doesn't matter so long as it's legal. Time zones are only a problem if you make them one.
- Understand that the needs of a team are relative to a given project, so cookie cutter team composition and project management won't work in software
- Accept that failure is always a risk
- operate with the assumption that teams that are skilled, empowered and motivated are more likely to succeed.
- Culture fit is a per team thing, if the team hates each other they won't work well no matter how much time and money you throw at it
Last thing isn't derived from the train of thought, just things I feel are true:
- Training and headcount is an investment that grows linearly over time, but can have exponential value. Retain people, not services.
- "you build it, you run it" will result in happier customers, faster pivoting. Don't adopt an application maintenance strategy

Random thought of the day. I'm sure I've been told the "common wisdom" is that you can take a job with a lower salary and enjoy a better work-life balance, or go gung-ho for the inner city jobs and earn way more but sacrifice your quality of life.
Anyone else found the complete opposite? The higher the salary I've had over my career, generally the *better* the working environment and the more the employer seems to care for, and value its employees. Not universally true I'm sure, and perhaps I'm just lucky about where I pick, but I've certainly had way more "high stress" situations in some of my lower paid, rather than higher paid roles.9 -
Data Disinformation: the Next Big Problem
Automatic code generation LLMs like ChatGPT are capable of producing SQL snippets. Regardless of quality, those are capable of retrieving data (from prepared datasets) based on user prompts.
That data may, however, be garbage. This will lead to garbage decisions by lowly literate stakeholders.
Like with network neutrality and pii/psi ownership, we must act now to avoid yet another calamity.
Imagine a scenario where a middle-manager level illiterate barks some prompts to the corporate AI and it writes and runs an SQL query in company databases.
The AI outputs some interactive charts that show that the average worker spends 92.4 minutes on lunch daily.
The middle manager gets furious and enacts an Orwellian policy of facial recognition punch clock in the office.
Two months and millions of dollars in contractors later, and the middle manager checks the same prompt again... and the average lunch time is now 107.2 minutes!
Finally the middle manager gets a literate person to check the data... and the piece of shit SQL behind the number is sourcing from the "off-site scheduled meetings" database.
Why? because the dataset that does have the data for lunch breaks is labeled "labour board compliance 3", and the LLM thought that the metadata for the wrong dataset better matched the user's prompt.
This, given the very real world scenario of mislabeled data and LLMs' inability to understand what they are saying or accessing, and the average manager's complete data illiteracy, we might have to wrangle some actions to prepare for this type of tomfoolery.
I don't think that access restriction will save our souls here, decision-flumberers usually have the authority to overrule RACI/ACL restrictions anyway.
Making "data analysis" an AI-GMO-Free zone is laughable, that is simply not how the tech market works. Auto tools are coming to make our jobs harder and less productive, tech people!
I thought about detecting new automation-enhanced data access and visualization, and enacting awareness policies. But it would be of poor help, after a shithead middle manager gets hooked on a surreal indicator value it is nigh impossible to yank them out of it.
Gotta get this snowball rolling, we must have some idea of future AI housetraining best practices if we are to avoid a complete social-media style meltdown of data-driven processes.
Someone cares to pitch in?14 -
Ok now I'm gonna tell you about my "Databases 2" exam. This is gonna be long.
I'd like to know if DB designers actually have this workflow. I'm gonna "challenge" the reader, but I'm not playing smartass. The mistakes I point out here are MY mistakes.
So, in my uni there's this course, "Databases 2" ("Databases 1" is relational algebra and theoretical stuff), which consist in one exercise: design a SQL database.
We get the description of a system. Almost a two pages pdf. Of course it could be anything. Here I'm going to pretend the project is a YouTube clone (it's one of the practice exercises).
We start designing a ER diagram that describes the system. It must be fucking accurate: e.g. if we describe a "view" as a relationship between the entities User and Video, it MUST have at least another attribute, e.g. the datetime, even if the description doesn't say it. The official reason?
"The ER relationship describes a set of couples. You can not have two elements equal, thus if you don't put any attribute, it means that any user could watch a video only once. So you must put at least something else."
Do you get my point? In this phase we're not even talking about a "database", this is an analysis phase.
Then we describe the type dictionary. So far so good, we just have to specify the type of any attribute.
And now... Constraints.
Oh my god the constraints. We have to describe every fucking constraint of our system. In FIRST ORDER LOGIC. Every entity is a set, and Entity(e) means that an element e belongs to the set Entity. "A user must leave a feedback after he saw a video" becomes like
For all u,v,dv,df,f ( User(u) and Video(v) and View(u, v, dv) and feedback(u, v, f) ) ---> dv < df
provided that dv and df are the datetimes of the view and the feedback creation (it is clear in the exercise, here seems kinda cryptic)
Of course only some of the constraints are explicitly described. This one, for example, was not in the text. If you fail to mention any "hidden" constraint, you lose a lot of points. Same thing if you not describe it correctly.
Now it's time for use cases.
You start with the usual stickman diagram. So far so good.
Then you have to describe their main functions.
In first order logic. Yes.
So, if you got the point, you may think that the following is correct to get "the average amount of feedback values on a single video" (1 to 5, like the old YT).
(let's say that feedback is a relationship with attribute between User and Video
getAv(Video v): int
Let be F = { va | feedback(v, u, va) } for any User u
Let av = (sum forall f in F) / | F |
return av
But nope, there's an error here. Can you spot it (I didn't)?
F is a set. Sets do not have duplicates! So, the F set will lose some feedback values! I can not define that as a simple set!
It has to be a set of couples, like (v, u), where v is the value and u the user; this way we can have duplicate feedback values in our set.
This concludes the analysis phase. Now, the design.
Well we just refactor everything we have done until now. Is-a relations become relationships, many-to-many relationships get an "association entity" between them, nothing new.
We write down on paper every SQL statement to build any table, entity or not. We write down every possible primary key or foreign key. The constraint that are not natively satisfied by SQL and/or foreign keys become triggers, and so on.
This exam is considered the true nightmare at our department. I just love it.
Now my question is, do actually DB designers follow this workflow? Or is this just a bloody hard training in Pai Mei style?6 -
so... not really a rant because i'm happy to be in the long-term zenlike state where i don't really give a fuck about anything anymore, but...
so today's my birthday (thanks in advance for all the semi-mandatory "cheers" reactions and such)
the agency i do temp jobs through sends money weekly (for the one week back) (which is the main and only reason i use them). they arrive at friday 12:25, so that's when i know to go "check" by withdrawing it, and it's also awesome because it's the best time to provide funds to reward myself (by booze/weed) at the end of the week.
last week, nothing came in. i called them and learned it was due to the contact person in the company i did job in being too late on sending the agency list of people who showed up at the work, i was told it's gonna arrive one week later together with the proper payment for the week-1,so effectively i was one week without any money (literally), but on the next week double was going to arrive, which is nice.
that next week of double was now. i found out that no double arrived, only single-value payment. i called them to ask why.
i was told that what arrived was the late payment, and the dude in company was again late with sending the presence list, so the other payment, for the proper week's work, will be a week late again.
so... that kinda ruined my financial planning tor tge week that's going to happen.
i guess my point (if i have any) is... funny how when someone fucks up, there's nobody for me to be angry at and hold responsible in any way, but when i have delays in my work due to delays upstream, nobody gives a shit about my excuses and it's my fault and i should have compensated, it was my responsibility and duty, and me not doing it (to my own detriment, for someone else) is me failing.
funny how the subjective dynamics of the world always somehow works out in a way where everyone else fucks up and i either have to suck it up and be okay with it otherwise i'm a selfish unreliable entitled asshole, or suck it up and extinguish their fire for them, otherwise i'm a selfish unreliable entitled asshole XD
anyone else noticed this in their life?
how does it work? what is the factor that decides whether you're in the "suck it up" class or the "fuck it, someone else will suck it up" class?
doesn't seem to (just) be the money(flow), i've seen this thing happen even in situations where the money/client dynamics were flowing the opposite way to what would be natural for the shit fall direction.4 -
Eric Thomas' Top 10 Rules For Success
1- Know what you want.
If you don’t know what you want, how will you know what to say yes to in your life? Stop taking every body else’s leftovers and step up and take what you deserve!
2- Work on your gift.
We all have our own individual talents, gifts and strengths. But those natural gifts will only become truly great by refining and nourishing them. Natural ability will get you started, but commitment and determination to achieve greatness is what will get you to where you want to be.
3- No excuses.
Stop using your circumstances, finances or current position in life as an excuse to justify why you aren’t working towards your goals. You are in charge. If you aren’t where you want to be, take a look in the mirror and ask yourself honestly- WHY? Take responsibility for you life once and for all.
4- Upgrade your values.
Your values dictate your behaviours. And your behaviours create your results. If you want to a different result, you need to change your behaviour.
5- You reap what you sow.
Nothing in life is free. It is up to you to determine the course of your life. If you want success, you need to do what it takes, daily, to get there. Don’t focus so much on being successful. Focus on solving problems, helping others, and adding value to people’s lives, and success will come.
6- Education is the great equaliser.
If you are at the bottom, you need to learn. If you are at the top, you still need to learn. Never, ever, ever stop growing and educating yourself.
7- What is your WHY?
Why do you wake up in the morning and hustle? Why do you do what you do? Knowing the answer to this question is the single most important thing to know about yourself if you want to become successful. When you know WHY you are doing what you do, you won’t ever quit, even on a bad day.
8- Have boundaries.
If you want to be a huge success, you have to be strict on yourself with how you spend your energy. Distractions will come in many forms, family, friends, TV, but you have to make sure that your time is being spent wisely.
9- Speak from the heart.
Transparency is attractive. Don’t be afraid to open up to the world and let yourself be seen.
10- Succeed as bad as you want to breathe.
Everybody wants to be successful. But not everybody is willing to do the work that it takes to become successful. When you are willing to get so uncomfortable, so out of your depth, so blind that you have no other choice but to be successful, THEN you will become successful. The only question you need to ask yourself is this. Am I willing?

I agree with many people on here that Front-End web development/design isn't what it used to be.
Things used to be simple: a static page. Then we decoupled design from description and we introduced CSS; nice, clean separation, more manageable - everything looks nice up to this point.
Introduce dynamic pages, introduce JavaScript. We can now change the DOM and we can make interactive, neat little webpages; cool, the web is still fun.
Years later, we start throwing backend concepts into the web and bloating it with logic because we want so much for the web to be portable and emulate the backend. This is where it starts to get ugly: come ASP, come single pages, partial pages, templates,.. The front-end now talks to a backend, okay. We start decoupling things and we let the logic be handled by the backend - fair enough.
Even later, we start decoupling the edge processes (website setup, file management, etc.) and then we introduce ugly JavaScript tools to do it. Then we introduce convoluted frameworks (Angular,..). Sometimes we find ourselves debugging the tools themselves (grunt, gulp, mapping tools,..) rather than focusing on the development itself (as per ITIL guidelines; focus on value), no matter how promising today's frameworks claim to be ("You get to focus on your business code"; yeah right, in practice it has turned out differently for me. More like "I get to focus on wasting copious amounts of time trying to figure out your tangled web").
Everything has now turned into an unfriendly, tangled web (no pun intended).
I miss the old days when creating things for the Web used to be fun, exciting and simple and it would invigorate passion, not hate.

Pulled into an 'emergency' meeting with a group of web designers deeply concerned a particular service wasn't going to meet all their requirements.
DevA: "For each page, Its going to be A LOT of work to retrieve all the data and store it's state. Every page load will require a round trip to the service."
DevB: "Yes, we aren't sure how the service should be changed to do what we need."
Mgr: "What is it not doing now? Doesn't the service already returns all the necessary data?"
DevA: "Well...um...its all the boolean fields. Some may be defaulted from the database or false because the user unchecked the box. We have to know which is which"
Me: "Why? Are you doing anything different in the UI? Checkbox will be true or false. What or who set that value is irrelevant"
DevC: "Well, it matters if the user didn't fill out all other other values."
Me: "How so?"
DevA: "Its matters because the values in the other fields. Its going to be A TON of work to figure out."
<mgr goes to the white board>
Mgr: "Lets map this out...what fields are you needing to trigger the state on?"
DevA: "Um...uh...the 'Approved' field...and um...'OK to Contact' field"
Mgr: "Just those two?"
DevA: "Yea..um...there are other fields, but whether or not to show the edit box depends on those two."
Me: "The service already returns data, you only have two fields to check? I don't see a need to change the service at all."
DevA: "Returning all that data, we are going have a serious scaling problem. We'll be hitting the service A LOT. All that javascript could cause performance problems too"
Me: "How much data are we talking about? Name, address, couple of booleans?"
DevA: "I have to serialize the data. All that logic is going to be reeeaaallly complicated. It might be better if the service returned only the data I need."
Me: "$64,000 question, how often is this feature going to be used on the web site? Maybe once? Few hundred a week?"
Mgr: "We have no idea. A lot of the data will be pre-populated and we're only sending out a few thousand invitations. More around the holidays...but honestly, not very many."
Me: "Changing that service only for this particular area of the web site isn't going to happen. Changing the UI is the only course of action."
DevA: "Oh frack I can't wait until this project is over."
DevA...how the funck do still have a job here? You wasted about half-hour of my time with your cry-baby crap. Where is my hammer...no...no..don't go there...ahhh...thanks devrant. Prison sentence diverted.2 -
Yesterday I almost ended my programming Carrier
Long story - I am enrolled in EC course which I cannot face for a single moment. Web development is something that had always excited me, and i wanted to make a room for myself here since childhood.
I cannot study what doesn't interest me. But that does not mean I hate learning. I have strong interest in learning things. Hence, I skipped two end-sem exam in the last semester. And utilized thar time to work on my project. I've been working on it since last 6 months. I learned more things in last one year than what I did in last 3 years at college.
My brother came to know I failed two exams in the last sem, yesterday. There were clouds flying over home for hours. What my family thinks is, I should get my degree. Whether I learn anything or not, but I should I get it. I must do graduation and what ever stuff I am working on can be done later. They don't understand the value of time and how fast things are changing.
I even got a client, who is willing to pay large amount for my platform. What my family thinks, is I am running for money, which is merely true.
What world we are living in. Parents and families don't want their children to get educated or well equipped with knowledge and values but want a printed degree in hand, which they think is enough to get a job.
The colony where I live, more than 80% graduates, that graduated in last 5 years with good numbers are unemployed.3 -
Proudest bug squash? Probably the time I fixed a few bugs by accident when I was just trying to clean up an ex-coworker's messy code.
So I used to work with a guy who was not a very good programmer. It's hard to explain exactly why other than to say that he never really grew out of the college mindset. He never really learned the importance of critical thinking and problem-solving. He did everything "by the book" to a point where if he ran into an issue that had no textbook solution, he would spin his wheels for weeks while constantly lying to us about his progress until one of us would finally notice and take the problem off his plate. His code was technically functional, but still very bad.
Quick Background: Our team is responsible for deploying and maintaining cloud resources in AWS and Azure. We do this with Terraform, a domain-specific language that lets us define all our infrastructure as code and automate everything.
After he left, I took on the work to modify some of the Terraform code he'd written. In the process, I discovered what I like to call "The Übervariable", a map of at least 80 items, many of them completely unrelated to each other, which were all referenced exactly once in his code and never modified. Basically it was a dynamic collection variable holding 80+ constants. Some of these constants were only used in mathematical expressions with multiple other constants from the same data structure, resulting in a new value that would also be a constant. Some of the constants were identical values that could never possibly differ, but were still stored as separate values in the map.
After I made the modification I was supposed to make, I decided I was so bothered by his shitty code that I would spend some extra time fixing and optimizing it. The end result: one week of work, 800 lines of code deleted, 30 lines added, and a massive increase in efficiency. I deleted the Übervariable and hardcoded most of the values it contained since there was no possible reason for any of them to change in the future. In the process, I accidentally fixed three bugs that had been printing ominous-sounding warnings to the console whenever the code was run.
I have a lot of stories about this guy. I should post some more of them eventually.2 -
can i work in any more horrible company than this?
> got a shitty macbook air as official work laptop. i am an Android dev btw, nd fuck knows how long it took to build apps on this, but it was still okay
> after 1 year some keys started getting slow to respond but still working fine
> recently a Senior dev raised request for better laptops and somhow we all got macbook pros woth good ram/processor
> returned my old laptop, got a mail after few seconds that my laptop has liquid damage! (in retrospect , i think i knew it as my bag once got drenched in rain)
> few days later, a mail chain starts where some guy is asking for $300 approval of fixes from my boss's boss!
now fuck knows how is it going to get paid, but i cant afford it on my monthly salary.
i am already on a tight crunch as my dad recently lost his job and i am paying emis for a car loan as well as a hand fracture loan, but i am surprised that am getting notified about this.
afaik,
1. the laptop's whole value is around $350 (some corporate quote that i once saw) .
2. the laptops should be fucking insured (we ourselves are a fuckin general insurance company) as its an obvious norm in corporate equipments. i shouldn't be penalised for this
3. i was working fine with this laptop and i can still work on it if given back.
4. this can be deducted at the time of fnf or from gratuity fund that these assholes hold onto until a guy completes 5 years and take it all for themselves if he doesn't.
5 i can buy this shitty laptop back and use it as my personal device, or get it repaired for less.
i don't even claim to have damaged it, why are they putting it on me 😭😭😭8 -
I have been debugging for like hours trying to figure out the cause an unknown bug spoiling my UI by making my elements overlap.
I'm working on a Unit Converter that takes kWh and then converts to mWh. (Logical Conversion: 1000 kWh = 1 mWh).
Just an easy shit i thought, using Javascript I just passed the dynamically generated kWh value to a function that takes maximum of 6 chars and multiply it by 0.001 to get the required result but this was where my problem started. All values came out as expected until my App hits a particular value (8575) and outputs a very long set of String (8.575000000000001), i couldn't figure the cause of this until i checked my console log and found the culprit value, and then i change the calculation logic from multiply by 0.001 to divide by 1000 and it came out as expected (8.575)
My question is that;
Is my math logically wrong or is this another Javascript Calculation setback?13 -
what is the purpose of a degree?
what value does it convey?
isnt it better if you just show all the work and projects youve done on github as proof of what kind of knowledge do you actually have? plus where you worked before on linkedin? thats not enough, right? a paper needs to decide how much knowledge you have? is that it?10 -
Looking for a second opinion/validation.
*Me: “Perhaps this simple and concise way to ensure the user doesn’t lose their data before they leave the page that requires non-zero yet minimal input from the user. (Read: ya gotta push a save/submit button)”
*Everyone else: Let’s pretend to read the user’s mind and perform relatively complicated functions behind the scenes, of which the user will most likely be unaware, that will add an undetermined amount of complexity to the development because we think it’s “where things are going,” by saving the value of a certain HTML element as it loses focus.
Edit: this is an exclusively-internally used app.4 -
Reverse engineering an applications internal object model and creating an database model for it...
The reason: Several versions of application exist, each deliver flat data by rest. The data is a complete potpourri of several different entities. *yaaaay*
Eg. an example fictional call (real call and data would get me in trouble I think....)
get_fiscal_report returning the fiscal data for _several_ companies, the companies _subsidiaries_ and the respective _segments_ for a _year_ with a key value enumeration.
So it's an happy fuck up of N:N associative data that usually would be a hierarchical relationship...
Year - Company
Each Company has subsidiaries
Each Company subsidiary has segments
Each segment has a fixed enumeration of keys
Each key has then the monetary value (e.g. 'operating_income' - 155_000 US-$)
Example is made up, but my data contains exactly such a lovely nested hierarchical data flattened and misnamed to a point where it's close to garbage.
Yaaaay.
I had now 6 days of untucking this mess to a usable database representation...
Sprinkling Unique Keys everywhere...
Running persist script...
Getting exceptions...
Changing associations...
Running persist script...
Screaming.
Changing associations...
Violently cursing.
Running persist script.
Starting sacrificing interns...
6 days.
I need a new brain and a format of my soul.

Reverse engineering proprietary software is really an morbid adventure.1 -
I just saw a news article (nope, not sharing it...don't want them to get the clicks) where they said it's now considered passive-aggressive to use the following emojis (the percentage is a non-specific n-value and N-value...probably 3...of how many younger folks think it makes you look "old" to use these):
1 - Thumbs up - 24%
2 - Red love heart - 22%
3 - OK hand - 20%
4 - Tick - 17%
5 - Poo - 17%
6 - Loudly crying face - 16%
7 - Monkey eye cover - 15%
8 - Clapping hands - 10%
9 - Lipstick kiss mark - 10%
10 - Grimacing face - 9%
I previously only ever used thumbs-up and checkmarks to signal that I understood the message sent to me. My new goal is to use as many of these as possible when messaging anyone under 30. If you are so butthurt by ANY emoji, then you certainly deserve what's coming to you.18 -
We had today a meeting in management that ended in a discussion about prevention instead of crisis and risk management.
Or to make it bit simpler: prevention instead of treatment.
In IT / management / government, treatment is usually the way - you let the crisis happen, despite knowing it could have been prevented, and treat the damage / crisis.
Needless to say, the discussion escalated like usual.
It's funny how managers are able to put sentences like: "it's important to have quality assurance like prevention but staying within budget should be priority" (loosely translated from German, it's hard - sorry)...
You mean the budget that exploded and quadrupled in size because you dumb fuckers pay no attention to quality assurance? Or the additional cost of hardware, maintenance etc. to compensate for the fuckups regarding performance evaluation and regression testing?
"We cannot prevent everything nor anticipate everything, it's safer to deal with an estimated risk than with the unknown"...
"But we'd need to invest in ..., which reduces value"
I could give more details, but I think the point is clear... the discussion became quite heated and the longer it went on, the more I wanted to have an morphine drop with suicide option...
Why do people hate prevention so much?
Is the concept that hard to understand? You prevent things to not deal with crisis.
You invest to prevent loss.
It's just one of these weeks where the only happiness consists of tipping the delivery guy with 20 % plus and getting an honest smile.

Last week I got told by an incoming CTO, a week old to the organisation, that I'm good for nothing and unable to produce any work. He told me that he'll replace me and put me in a team where I'm more resourceful as I have been consistently underperforming. (He doesn't understand data science yet fyi) Then, he informed he's hiring 5 new teams members.
Me (junior data scientist) being really passionate about work was shook to hear this. So much so that it took me a week to even recover from it. I have considered counselling sessions too.
Week later, 5 new team members decide to flip his offer and not join. Another existing senior member decides to leave as well. Meanwhile, major issues in existing systems emerge and only I could solve the same. Still haven't heard back any from him though.
Is this the industry standard though ? Is this how CTOs normally function ? Throwing shit at people without knowing their value or valuing their efforts ? Especially with junior developers. It's only been 2 years in this profession and I've not met more than 3 genuine and helpful people. Maybe it's just my organization.9 -
I usually crib about how stupid people are and how I struggle to stay afloat.
Let's switch some gears now. A post about some good people, product, and processes.
You know what the common theme here is?
The goodness here cannot be measured. Your first interaction with them makes you feel so comfortable that you start feeling butterflies.
These people just keep on giving. They are selfless. They are pure. They actually care.
And when you think it's done, then they give you some more.
What blows me away is, they don't expect or accept anything in return. Absolutely nothing. Not even a simple thank you.
And they are like a wizard. They walk into your life when you least expect them but need them the most. And when the task is done, they'll be gone before you even know.
No lingering, no drama, no bullshit. Just pure goodness.
Like my ex-lead in current company, I have a very senior guy in neighbouring team (for which they were gonna hire me initially), who also happened to interview me, is a gem.
He takes care of me like his own younger brother. Supports me and always answers my queries no matter how occupied he is.
And same is with good products and processes. They feel effortless. So smooth and add exceptional value to your existence. They give rise to wonderful companies.
You'd never experience a single negative aspect about them. No matter how much you try, things will just keep getting better until they don't need to.
And then they'll be long gone. Never to be seen again and never to be forgotten.
You cherish them only in your memory and wish they lasted longer. But they didn't because the purpose was served.
Such people and experiences inspire me. They push me to become a better human.
No matter how the world is or how it treats me, I must always live with high values and be a better version of past self.
The other evening, I was conversing with my mother where we spoke about some family friends who are insanely wealthy but humble and kind.
Mom and I mutually agreed that they don't have such good traits because they are wealthy, but they are wealthy because they live with humility, kindness, and pure intentions.
World is surely a beautiful place because of such people and I aspire to be one. May lord guide me well :)3 -
It is truly satisfying when you sucessfully extend a complex system in a seamless way where the narrow-minded user isn't able to recocognise any change.

The split second feeling of EXECUTE an UPDATE and SET value without putting WHERE clause.
I froze for a moment with cold sweat that I don't know what to do. My mind went blank.
Thank God it is just the entire list of customer details that is not relate to money issue.
Anyone can suggest the best practice for this type of accident UPDATE / DELETE?
Does using BEGIN TRANS ROLLBACK is safer way to execute?5 -
Found a clever little algorithm for computing the product of all primes between n-m without recomputing them.
We'll start with the product of all primes up to some n.
so [2, 2*3, 2*3*5, 2*3*5*,7..] etc
prods = []
i = 0
total = 1
while i < 100:
....total = total*primes[i]
....prods.append(total)
....i = i + 1
Terrible variable names, can't be arsed at the moment.
The result is a list with the values
2, 6, 30, 210, 2310, 30030, etc.
Now assume you have two factors,with indexes i, and j, where j>i
You can calculate the gap between the two corresponding primes easily.
A gap is defined at the product of all primes that fall between the prime indexes i and j.
To calculate the gap between any two primes, merely look up their index, and then do..
prods[j-1]/prods[i]
That is the product of all primes between the J'th prime and the I'th prime
To get the product of all primes *under* i, you can simply look it up like so:
prods[i-1]
Incidentally, finding a number n that is equivalent to (prods[j+i]/prods[j-i]) for any *possible* value of j and i (regardless of whether you precomputed n from the list generator for prods, or simply iterated n=n+1 fashion), is equivalent to finding an algorithm for generating all prime numbers under n.
Hypothetically you could pick a number N out of a hat, thats a thousand digits long, and it happens to be the product of all primes underneath it.
You could then start generating primes by doing
i = 3
while i < N:
....if (N/k)%1 == 0:
........factors.append(N/k)
....i=i+1
The only caveat is that there should be more false solutions as real ones. In otherwords theres no telling if you found a solution N corresponding to some value of (prods[j+i]/prods[j-i]) without testing the primality of *all* values of k under N.13 -
It's been a while since I've heard a consensus of a moronic idea from the corner offices. I was invited to a department planning meeting (just to listen, not necessarily engage or add value) and discussion went to the development of a mobile app.
Mgr1: "The CEO has the net present value of the mobile project as $20 million. Where did he get that number?"
VP: "No idea."
Mgr2: "How will it be any different than our web site that is already mobile compliant?"
VP: "It is to gain market share"
Mgr3: "Market share from who? A mobile app is not going to increase our customer base. At best, it will only move some of our existing customers to mobile. No way it would scale to those numbers."
VP: "The primary benefit is so customers can browse offline."
Mgr2: "Offline browsing isn't listed in the milestones."
Mgr1: "We're not going to push and keep gigs of data up-to-date on someone's phone just for random times they don't have internet access."
VP: "I guess that's right. We can push our pdf catalog. That's only a few hundred meg."
Mgr2: "Pushing the catalog? That's not on the listed milestones"
VP: "Its all assumed."
Mgr3: "Who owns this project? Web team is already maxed to capacity."
Mgr2: "Marketing team only has 3 developers, we can't take on anything as complex as a mobile app and support the existing processes."
Mgr1: "What about the network infrastructure and PCI compliance? We're talking about a system for the web site and another for mobile, right?"
Mgr2: "Who is going to manage all the versions in the app stores and future changes to the mobile platform?"
Mgr4: "Not us"
Mgr2: "Nope"
Mgr1: "OK, good. Its very likely this project will be dead on arrival at the next company strategic meeting."
VP: "Mobile the only project on the strategic meeting agenda. Sorry guys, it's happening. We're not going to leave $20 million sitting on the table.
<awkward silence>
VP: "Next item of business ..."3 -

I am in a situation where I am tired to give suggestions or implement any improvements to the company's app. I am in a situation where I will just do as told, nothing more, nothing less.
Regardless of how many suggestions or improvements I had made, the boss is constantly sceptically asking for "BLACK AND WHITE " proof. Sometimes, something does not require proof but cause and effect. As the application constantly prompts a DataType issue, which is a common bug in this app! I declare datatype the issue went away.
I wonder how this application can go further when they declare every variable as `var`, not using `const` for constant value, and redundant methods everywhere, most methods are not specific (in dart when you do not specify the method, the method become `dynamic`), a long list of nested if-else for something can be easily solved with switch case, etc.
So, today, right now, I will revert every improvement, and keep the original structure. If anything goes wrong, I know why it happens (deep down I will say "I told you so"). I am here to work for food, not to reinvent the wheel.
I'm so exhausted to the point where I will just go along and tell my co-worker "as you wish"
No more me suggesting.
No more me giving ideas.
No more me pointing the mistakes .
I will let them find out themselves is much better than I say it, just to prevent getting unnecessary hatred from them.
The best punishment to give somebody is to never mention their mistake let their ego do the job of consuming them into ignorance and asleep, and never wake them up. Let them commit the same mistakes repetitively until them realised there's no way to revert.5 -
So, I've had a personal project going for a couple of years now. It's one of those "I think this could be the billion-dollar idea" things. But I suffer from the typical "it's not PERFECT, so let's start again!" mentality, and the "hmm, I'm not sure I like that technology choice, so let's start again!" mentality.
Or, at least, I DID until 3-4 months ago.
I made the decision that I was going to charge ahead with it even if I started having second thoughts along the way. But, at the same time, I made the decision that I was going to rely on as little external technology as possible. Simplicity was going to be the key guiding light and if I couldn't truly justify bringing a given technology into the mix, it'd stay out.
That means that when I built the front end, I would go with plain HTML/CSS/JS... you know, just like I did 20+ years ago... and when I built the back end, I'd minimize the libraries I used as much as possible (though I allowed myself a bit more flexibility on the back end because that seems to be where there's less issues generally). Similarly, any choice I made I wanted to have little to no additional tooling required.
So, given this is a webapp with a Node back-end, I had some decisions to make.
On the back end, I decided to go with Express. Previously, I had written all the server code myself from "first principles", so I effectively built my own version of Express in other words. And you know what? It worked fine! It wasn't particularly hard, the code wasn't especially bad, and it worked. So, I considered re-using that code from the previous iteration, but I ultimately decided that Express brings enough value - more specifically all the middleware available for it - to justify going with it. I also stuck with NeDB for my data storage needs since that was aces all along (though I did switch to nedb-promises instead of writing my own async/await wrapper around it as I had previously done).
What I DIDN'T do though is go with TypeScript. In previous versions, I had. And, hey, it worked fine. TS of course brings some value, but having to have a compile step in it goes against my "as little additional tooling as possible" mantra, and the value it brings I find to be dubious when there's just one developer. As it stands, my "tooling" amounts to a few very simple JS scripts run with NPM. It's very simple, and that was my big goal: simplicity.
On the front end, I of course had to choose a framework first. React is fine, Angular is horrid, Vue, Svelte, others are okay. But I didn't want to bother with any of that because I dislike the level of abstraction they bring. But I also didn't want to be building my own widget library. I've done that before and it takes a lot of time and effort to do it well. So, after looking at many different options, I settled on Webix. I'm a fan of that library because it has a JS-centric approach. There's no JSX-like intermediate format, no build step involved, it's just straight, simple JS, and it's powerful and looks pretty good. Perfect for my needs. For one specific capability I did allow myself to bring in AnimeJS and ThreeJS. That's it though, no other dependencies (well, at first, I was using Axios because it was comfortable, but I've since migrated to plain old fetch). And no Webpack, no bundling at all, in fact. I dynamically load resources, which effectively is code-splitting, and I have some NPM scripts to do minification for a production build, but otherwise the code that runs in the browser is what I actually wrote, unlike using a framework.
So, what's the point of this whole rant?
The point is that I've made more progress in these last few months than I did the previous several years, and the experience has been SO much better!
All the tools and dependencies we tend to use these days, by and large, I think get in the way. Oh, to be sure, they have their own benefits, I'm not denying that... but I'm not at all convinced those benefits outweighs the time lost configuring this tool or that, fixing breakages caused by dependency updates, dealing with obtuse errors spit out by code I didn't write, going from the code in the browser to the actual source code to get anywhere when debugging, parsing crappy documentation, and just generally having the project be so much more complex and difficult to reason about. It's cognitive overload.
I've been doing this professionaly for a LONG time, I've seen so many fads come and go. The one thing I think we've lost along the way is the idea that simplicity leads to the best outcomes, and simplicity doesn't automatically mean you write less code, doesn't mean you cede responsibility for various things to third parties. Those things aren't automatically bad, but they CAN be, and I think more than we realize. We get wrapped up in "what everyone else is doing", we don't stop to question the "best practices", we just blindly follow.
I'm done with that, and my project is better for it! -

Below is a transcript from work Slack today. Only the names and some code are changed. It ended up causing a bit of drama. DevRanters, what do you take from this?
---
Delivery Lead:
Hey Gang. What's the blocker for FEATURE-123?
Dev1:
FEATURE-122 crashed on iOS app when viewing Feature Introduction page.
Teach Lead:
I've talked about this with Dev1 on a side channel.
And diagnosed the stack trace.
It looks like there is/was some bad handling of a List in the Feature Introduction view logic.
But this is confined to changes that Dev2 is still working on.
(It's not present in master)
Dev2, what's your current position on this?
Dev2:
I have tested at my end with Dev1 but it seems to be working fine
Tech Lead:
There is a race condition related to the use of someList.first()
My guess is that theres a Flow of those lists defined, with an initial value of emptyList
And that on your machine, that Flow is updating with a new value quickly enough that it doesn't matter.
But on Dev1's, for whatever reason, it doesn't get there in time, hits the empty list and falls over.
The logic that's performing the first() needs to gracefully handle empty lists as well.
Dev2:
Where is that logic called?
Tech Lead:
Here's the stack trace Dev1 provided in our conversation earlier:
Caused by: kotlin.NoSuchElementException: List is empty.
...
at 3 iosApp 0x00000000 kfun:kotlin.NoSuchElementException#<init>(kotlin.String?){} + 00
at 4 iosApp 0x0000000 kfun:kotlin.collections#first@kotlin.collections.List<0:0>(){0§<kotlin.Any?>}0:0 + 000
...
at 9 iosApp 0x0000000 kfun:kotlin.coroutines.native.internal.BaseContinuationImpl#resumeWith(kotlin.Result<kotlin.Any?>){} + 0000
This line:
kfun:kotlin.collections#first@kotlin.collections.List<0:0>()
...says that it's first() being called on an empty list.
Dev1:
FYI: Dev3/Dev4/myself are seeing the same issue with the same stack-trace above.
Tech Lead:
So Dev2, have you introduced such a call?
Because I checked master branch and there isn't one, in that version of the file.
Ok, I'll check your working branch Dev2
...
Yes you have here:
var processed1 = someList.first()
var processed2 = someList.first()
...
Lines 123, 124.
Solution looks really straightforward guys.
Dev2:
Okay, I will fix that and push the change
Tech Lead:
Check if someList is empty and allow for generating / handling null processedValues in the view.
Now; I'm going to be straight with you here.
This issue has been discussed over several hours today.
I expect that either one of you could have gone through the process I did in the last 10 minutes above, and resolved it in the same way :point_up:
Dev2:
I went on a break and it's not reproducible on my machine
Tech Lead:
I didn't reproduce it on mine either.
Dev1:
Dev2 and myself are now on sharing screen to sort this issue out. Hope to update back later.
Tech Lead:
<Screen shot of diff with changed code>
:point_up: That change should do it.
Dev2:
Already have pushed the change.
Tech Lead:
...just seen it, is good - same approach :ok_hand:
Dev1 please let us know when tested on your machine.
Dev1:
That does it. It fixes the issues. Thank you, Dev2. I will pick it off from here.
Tech Lead:
Glad to hear it guys.
Dev1:
I have to say this that it is not because we are not working on the issue - Dev2 and myself (together with Dev3/Dev4) have been on this issue all this morning. It just difficult to connect the dot when it wasn't reproducable on Dev2's machine. I brought the issue up because I wanted to switch to working on other tickets while waiting for this to resolve. Still thank you largely for Dev2's work and your keen eyes that spot and resolve the issue quickly.
Tech Lead:
Noted Dev1.
I think the take-away has to be to read the stack-trace carefully... don't worry - we've all been guilty of not reading the error in full, at some point.
The stack trace said that the 'first' element is being referenced from an empty list - that's just logically impossible, right?
Looking for that call to first, we saw it wasn't in the code before, and is after (two of them, in fact).
So then we ask ourselves, how can we deal with an empty list - and then solution almost presents itself.
It didn't really take reproduction of the error to resolve.
Maybe working with a new tech stack creates an anxiety that every issue faced will have a complex solution related to that stack; but I think you'll agree, this particular issue really just required a deep breath and your trusty 'debugging skills 101'... don't lose them! :smiling_face:4 -
Of course, I just swiped the wrong way on my fucking laptop trackpad and list everything I just typed. FUCKING MARVELOUS.
TL;DR: Teacher stopped me from being productive. Principal almost called cops on me. Nearly threw chair at librarian.
So I'm at school yesterday, and we have a presenter in 2nd hour, so naturally, I'm gonna be on my computer doing things for other classes at the same time. Efficiency. Teacher doesn't like it, I refuse to put the computer away telling her that I'll be more productive and still pay attention, which HAS BEEN PROVEN MIND YOU, but she ends up calling security on me and I get sent down to the principal's office.
I talk to him, and he says 'Yeah, I know it's in the way, but you have to follow the directive given by the teachers.' Fine, fuck it. Won't go to her class for third hour. (I have her twice in a row for two different classes.) Next day.
I walk in, asking her if she's gonna do the same thing she did yesterday, hoping that she realized her error and will fix it, but no. She says I STILL can't have the computer out. I'm sorry, do you not realize I have 6 other fucking classes, most of which are required to graduate, unlike YOURS, as well as a FUCKING COLLEGE CLASS TONIGHT?! She gives the ultimatum. 'Obey or leave.' Fine, I'll leave. I go to the principal's office again, he must have a stick up his ass or something today because he's not budging. We argue for a while and he gives a WORSE ultimatum: 'Obey, Go to the Library, In House Suspension, or I'll call the police.' What the actual FUCK MAN?! You're gonna call the POLICE on a NONVIOLENT STUDENT?! Are you fucking MAD? I keep trying to tell him that there's an easy solution to this, but as he's getting up to call the cops, I say 'Fine! I'll go to the library!' He follows me over to make sure I don't kill anyone on the way.
I slam the door to the library open, and when I walk in, the librarian is there at her computer, and she asks 'Where are you coming from?' 'Principal!' 'I need a pass-' 'Well, I'm sorry, I can't exactly get anything for you right now, I was just sent down here.' She says 'Either way, I need some kind of note or pas-' 'Listen, I'm not in the mood for any of this right now. Please, just leave me be.' She then tries to say something, but I cut her off quickly, 'Just back off and leave me alone right now. The more you push it, the more you're gonna make me want to throw this chair!' Imagine the volume just gradually getting louder on that last one. She quickly runs out and talks to the security desk or something, which is right outside the library door, but she's the only one who comes in, thankfully. I was expecting to be fucking dragged out for no good reason. I'm loud, not violent. I have no history of violence.
So yeah. Here I am in the school library, angrily tapping away at my keyboard, trying not to throw the entire table to the fucking moon. All because this broken-ass public school system has no idea how to deviate from the norm when it's actually productive and efficient to do so. And now, the obligatory:

Major rant incoming. Before I start ranting I’ll say that I totally respect my professor’s past. He worked on some really impressive major developments for the military and other companies a long time ago. Was made an engineering fellow at Raytheon for some GPS software he developed (or lead a team on I should say) and ended up dropping fellowship because of his health. But I’m FUCKING sick of it. So fucking fed up with my professor. This class is “Data Structures in C++” and keep in mind that I’ve been programming in C++ for almost 10 years with it being my primary and first language in OOP.
Throughout this entire class, the teacher has been making huge mistakes by saying things that aren’t right or just simply not knowing how to teach such as telling the students that “int& varOne = varTwo” was an address getting put into a variable until I corrected him about it being a reference and he proceeded to skip all reference slides or steps through sorting algorithms that are wrong or he doesn’t remember how to do it and saying, “So then it gets to this part and....it uh....does that and gets this value and so that’s how you do it *doesnt do rest of it and skips slide*”.
First presentation I did on doubly linked lists. I decided to go above and beyond and write my own code that had a menu to add, insert at position n, delete, print, etc for a doubly linked list. When I go to pull out my code he tells me that I didn’t say anything about a doubly linked list’s tail and head nodes each have a pointer pointing to null and so I was getting docked points. I told him I did actually say it and another classmate spoke up and said “Ya” and he cuts off saying, “No you didn’t”. To which I started to say I’ll show you my slides but he cut me off mid sentence and just yelled, “Nope!”. He docked me 20% and gave me a B- because of that. I had 1 slide where I had a bullet point mentioning it and 2 slides with visual models showing that the head node’s previousNode* and the tail node’s nextNode* pointed to null.
Another classmate that’s never coded in his life had screenshots of code from online (literally all his slides were a screenshot of the next part of code until it finished implementing a binary search tree) and literally read the code line by line, “class node, node pointer node, ......for int i equals zero, i is less than tree dot length er length of tree that is, um i plus plus.....”
Professor yelled at him like 4 times about reading directly from slide and not saying what the code does and he would reply with, “Yes sir” and then continue to read again because there was nothing else he could do.
Ya, he got the same grade as me.
Today I had my second and final presentation. I did it on “Separate Chaining”, a hashing collision resolution. This time I said fuck writing my own code, he didn’t give two shits last time when everyone else just screenshot online example code but me so I decided I’d focus on the PowerPoint and amp it up with animations on models I made with the shapes in PowerPoint. Get 2 slides in and he goes,
Prof: Stop! Go back one slide.
Me: Uh alright, *click*
(Slide showing the 3 collision resolutions: Open Addressing, Separate Chaining, and Re-Hashing)
Prof: Aren’t you forgetting something?
Me: ....Not that I know of sir
Prof: I see Open addressing, also called Open Hashing, but where’s Closed Hashing?
Me: I believe that’s what Seperate Chaining is sir
Prof: No
Me: I’m pretty sure it is
*Class nods and agrees*
Prof: Oh never mind, I didn’t see it right
Get another 4 slides in before:
Prof: Stop! Go back one slide
Me: .......alright *click*
(Professor loses train of thought? Doesn’t mention anything about this slide)
Prof: I er....um, I don’t understand why you decided not to mention the other, er, other types of Chaining. I thought you were going to back on that slide with all the squares (model of hash table with animations moving things around to visualize inserting a value with a collision that I spent hours on) but you didn’t.
(I haven’t finished the second half of my presentation yet you fuck! What if I had it there?)
Me: I never saw anything on any other types of Chaining professor
Prof: I’m pretty sure there’s one that I think combines Open Addressing and Separate Chaining
Me: That doesn’t make sense sir. *explanation why* I did a lot of research and I never saw any other.
Prof: There are, you should have included them.
(I check after I finish. Google comes up with no other Chaining collision resolution)
He docks me 20% and gives me a B- AGAIN! Both presentation grades have feedback saying, “MrCush, I won’t go into the issues we discussed but overall not bad”.
Thanks for being so specific on a whole 20% deduction prick! Oh wait, is it because you don’t have specifics?
Bye 3.8 GPA
Is it me or does he have something against me?7 -
An anti-rant: I just made some code and out of nowhere it suddenly had an awesome feature that I didn't even program. No, not a euphemism for "bug", an actual feature.
Here's the story: A few months ago I made a shortcut for "System.out.println(…)" called "print(…)". Then I developed it further to also print arrays as "[1,2,3]", lists as "{1,2,3}", work with nested arrays and lists and accept multiple arguments.
Today I wanted to expand the list printing feature, which previously only worked for ArrayLists, to all types of List. That caused a few problems, but eventually I got it to work. Then I also wanted to expand it to all instances of Collection. As a first step, I replaced the two references to "List" with "Collection" and magically, no error message. So I tested it with this code:
HashMap<Integer, String> map = new HashMap<>();
map.put(1, "1");
map.put(2, "");
map.put(3, "a");
print(map);
And magic happened! The output was:
{1=1, 2=, 3=a}
That's awesome! I didn't even think yet about how I wanted to display key-value pairs, but Java already gave me the perfect solution. Now the next puzzle is where the space after the comma comes from, because I didn't program that in either.
I feel a bit like a character in "The subtle knife", who writes a barebones program to communicate with sentient elementary particles (believe me, it makes sense in context) and suddenly there's text alignment on the left and right, without that character having programmed any alignment.4 -
Debugging an elusive database query problem. Attached to server process about 10 steps into the call stack trying to figure out why a a column value is not being properly cast. In comes Windows. You picked the most inappropriate time to restart for updates without asking me. Restart VM, authenticate with VPN, wait for 2FA, start up Visual Studio, enter credentials for the millionth time to authenticate with version control since the remember me checkbox doesn't work, open solution. Now where was I? Then Windows pops up a notification to inform me the updates couldn't be installed. The following comic strip comes to mind.

I was teaching a friend of mine how CSS works for her exam and we reach the point where she had to style the tables and she reads:
To avoid having spacing between table cells you can use:
border-collapse: collapse
[...]
border-collapse can also have value "separate"
She fucking freaked out like "WHAT THE FUCK IS EVEN THE SENSE OF IT? SHOULD I HAVE BORDER SEPARATE: SEPARATE? WHY THE FUCK SHOULD I WRITE THAT TWICE? HOW THE FUCK DOES THIS EVEN WORK OUT?"
I just loved how she doesn't know how to make a website but she already hates CSS before even using it on an actual browser2 -
One thing I truly fucking dislike about the development life is knowing about server administration. I think that the mental hurdle that is to develop a huge application, make a stable dev environment, learn all the tools, tricks, techniques, modern standards, processes whatever, detailing software engineering are way tf too much to also handle server admin shit.
We don't have anyone at work that deals with that, and as such my devs need to know how to do entire series of maintenance shit that just takes time and effort plus hours of notetaking and study. I mean I get it, they should know their way around a linux environment enough to troubleshoot issues that are related to the os when working with some tools, but fuuuuuuuck me man, setting up a server, even for the holy grail of easy (standard lamp stack) takes way tf too much.
Wish we could have a dedicated server admin in the team.
I know where my faults are, setting up servers is something that I know but just can't be assed with in terms of keeping up, I wish we had a devops dedicated server admin deployment guru cuz I really cannot stand losing hours doing this shit.
It also diminishes good s admins in value, "weLl ThE deVs caN do It" YEAH BITCH but wouldn't it be nice to have an expert concentrating on JUST THAT?

Progress on my sudoku application goes well. Damn, what is javascript fantastic. While the code of the previous version that I posted here was alright I did decide that i want to split code and html elements after all. I have now a puzzle class doing all resolving / validating and when a field is selected or changed, it emits an event where the html elements are listening to. It also keeps all states. So, that's the model. puzzle.get(0,1).value = 4 triggers an update event. It also tracks selection of users because users selecting fields is part of the game. I can render full featured widgets with a one liner. Dark mode and light mode are supported and size is completely configurable by changing font-size and optional padding. So far, painless. BUT: i did encounter some stuff that works under a CSS class, but not if I do element.style.* =. Made me crazy because I didn't expect that.19

So while exploring some new ideas, I decided to figure out if I could use variables in the known set to determine the bounds of variables in the unknown set.
The variables in question are algebraic identities derived from the semiprimes, so you already know where this is going.
The existing known set is 1194 identities.
And there are, if I recall, roughly two dozen unknowns.
Many knowns have the unknowns as their factors. The d4 product set for example is composed of variables d4a, d4u, d4z, d4z9, d4z4, d4alpha, d4theta, d4omega, etc.
The component variables themselves are unknown, just their products are known. Anyway.
What I've found interesting is if you know the minimum of some of these subsets, for example d4z is smallest out of the d4's for some semiprimes, then you know the upperbound of both the component variables d4 and z.
Unless of course either of them is < 1.
So the order of these variables, based on value, changes depending on the properties of the semiprime, which I won't get into. Most of the time the order change is minor, but for some variables they can vary a lot between semiprimes, rapidly shifting their rank in the known set. This makes it hard to do anything with them.
And what I found myself asking, over and over again, was if there was a way to lock them down? Think of it like a giant switch board, where flipping one switch lights up N number of others, apparently at random. But flipping some other switch completely alters how that first switch works and what lights it seemingly interacts with. And you have a board of them thats 1194^2 in total. So what do you do?
I'd had a similar notion a while back, where I would measure relative value in the known set, among a bunch of variables, assign a letter if the conditions were present, and generate a string, called a "haplotype."
It was hap hazard and I wrote a lot of code to do filtering, sorting, and set manipulation to find sets of elements in common, unique elements, etc. But the 'type' strings, a jumble of random letters, were only useful say, forty percent of the time. For example if a semiprime had a particular type starting with a certain series of letters, 40% of the time a certain known variable was guaranteed to be above a certain variable from the unknown set...40%~ of the time.
It was a lost cause it seemed.
But I returned to the idea recently and revamped the entire notion.
Instead what I would approach it from a more complete angle.
I'd take two known variables J and K, one would be called the indicator, and the other would be the 'target'.
Two other variables would be the 'component' variables (an element taken from the unknown set), and the constraint variable (could be from either the known or unknown set).
The idea was that relationships between the KNOWN variables (an indicator and a target variable) could be used to indicate the rank relationship between the unknown component variable and the constraint variable.
You'd think this wouldn't work either, but my intuition was there were so many seemingly 'random' rank changes of variables in the known set for any two semiprimes, that 1. no two semiprimes ever shared the same order for every variable, and 2. the order of the known variables had to be leaking information about the relationships of the unknown variables.
It turns out my intuition was correct.
Imagine you are picking a lock, and by knowing the order and position of the first two pins, you are able to deduce the relative position of two pins further back that you can't reach because of the locks security features. It doesn't let you unlock the lock directly, but by knowing this, if you can get past the lock's security features, you have a chance of using information about the third pin to get a better, if incomplete, understanding about the boundary position of the last pin.
I would initiate a big scoring list, one for each known element or identity. And then I would check it in tandem like so:
if component > constraint and indicator > target:
indicator[j]+= 1
This is a simplication, but the idea was to score ALL such combination of relationship, whether the indicator was greater than the target at the same time a component was greater than a constraint, or the opposite.
This worked out to four if checks and four separate score lists.
And by subtracting one scorelist from another, I could check for variables that were a bad fit: they'd have equal probability of scoring for example, where they were greater than the target one time, and then lesser than it for another semiprime.
So for any given relationship, greater or lesser between any unknown variable and constraint variable, I could find any indicator variable and target variable whose relationship strongly correlated to the unknown's.18 -

In other news my prime generator has exhaustively been checked against, all primes from 5 to 1 million. I used miller-rabin with k=40 to confirm the results.
The set the generator creates is the join of the quasi-lucas carmichael numbers, the carmichael numbers, and the primes. So after I generated a number I just had to treat those numbers as 'pollutants' and filter them out, which was dead simple.
Whats left after filtering, is strictly the primes.
I also tested it randomly on 50-55 bit primes, and it always returned true, but that range hasn't been fully tested so far because it takes 9-12 seconds per number at that point.
I was expecting maybe a few failures by my generator. So what I did was I wrote a function, genMillerTest(), and all it does is take some number n, returns the next prime after it (using my functions nextPrime() and isPrime()), and then tests it against miller-rabin. If miller returns false, then I add the result to a list. And then I check *those* results by hand (because miller can occasionally return false positives, though I'm not familiar enough with the math to know how often).
Well, imagine my surprise when I had zero false positives.
Which means either my code is generating the same exact set as miller (under some very large value of n), or the chance of miller (at k=40 tests) returning a false positive is vanishingly small.
My next steps should be to parallelize the checking process, and set up my other desktop to run those tests continuously.
Concurrently I should work on figuring out why my slowest primality tests (theres six of them, though I think I can eliminate two) are so slow and if I can better estimate or derive a pattern that allows faster results by better initialization of the variables used by these tests.
I already wrote some cases to output which tests most frequently succeeded (if any of them pass, then the number isn't prime), and therefore could cut short the primality test of a number. I rewrote the function to put those tests in order from most likely to least likely.
I'm also thinking that there may be some clues for faster computation in other bases, or perhaps in binary, or inspecting the patterns of values in the natural logs of non-primes versus primes. Or even looking into the *execution* time of numbers that successfully pass as prime versus ones that don't. Theres a bevy of possible approaches.
The entire process for the first 1_000_000 numbers, ran 1621.28 seconds, or just shy of a tenth of a second per test but I'm sure thats biased toward the head of the list.
If theres any other approach or ideas I may be overlooking, I wouldn't know where to begin.16 -
Fixed a high priority bug today just prior to release. There was 100% test coverage. The tests pass both before and after the change. The product behavior is correct now where it wasn't before. Just one more reminder that test coverage does not equate to either quality or correctness. Tests are alarms (at best), and quality of tests are no better an any chunk of code. All tests have costs, but not all have value. All reasons why I am skeptical of the value of code coverage, TDD, or anything that posits that "all tests are good".6

One of the devs changed the const value of one of the variables to have UTF 8 characters. For "cleaner meaning".
Sometimes I just want to electrocute people ...
The reason this didn't pop up all the time was because the test system triggered one call with the header - whenever said dev pushed changes...
And yeah. Test failures can be ignored.
Why bother? Just continue meddling in shit.
I'm glad for the dev that I'm in home office... :@
TLDR: Dev changed const value without thinking, ignoring test failures and I had the fun of debunking for 2 days a mysterious HAProxy failure due to HTTP header validation... -
Is it OK to punch a game dev who codes stupid numeric bugs?
So my wife got into Stardew Valley, that admittedly awesome comfort game farming simulator.
She went pretty far in the game, and found some item that was supposed to highly increase the damage she could inflict onto cute little monster thingies.
It didn't work as intended.
Since equipping the piece of shit all her hits did 0 damage. She tossed the item away but the problem persisted. And on and on...
She took to the googles to try and find some explanation, and apparently that is a fairly common bug for mobile devs.
Then she called in the big guns (that is how I'm calling myself in this case, you will see why).
Apparently there is some buggy piece of shitcode somewhere in the game with a numerical insecure routine that overflows the attack modifier. I.e. if it was supposed to increase from 1.990 to 2.010, it actually went all the way down to -0.4.
She was lucky her attacks weren't increasing the monsters' HP.
We found a forum post where some dude said that he managed to edit the game save file and reset the negative-value attack increase modifier variable. Seems easy enough at first, but my wife uses iOS. Nothing is ever so straightforward with apple stuff.
We did get to the save file, she emailed it to me (the file has no extension and no line breaks in it, so we facepalm'd on a couple attempts at editing it directly).
I finally manage to get it into my personal 11-yo laptop... that won't open a single line file that big.
Cue the python terminal. Easy enough to read the file into a string var and search for the buggy XML tag. Edit the value and overwrite into a new file. Send it back to her by email. Figure out how to overwrite the file in iOS.
Some tense moments while the game reloads... and it works!!!! Got some serious hubby goodwill points here.
Srsly, this troubleshoot process is not for technophobes. It is out of reach to pretty much every non-techy user.
And now back to the original question: If I ever manage to find the kid who coded a game-breaking numerically unsafe routine and shipped it as if every test in the planet had waved it bye-bye, can I punch them? Or maybe buy them a beer, let's see how I get to cash that hubby goodwill tonight :)7 -
So, I'm going to apologize before I even start this rant...lol. I am the Senior level web developer at my job and have been there for around 12 years now. I have been there at least 2 times as long as everyone else.
I also want to say that my boss is a good man and I really like my coworkers and he has helped me through a lot over those 12 years and I don't want to sound ungrateful. However, I am so fed up with my job. I think the only reason I stay is the fear of the unknown of switching jobs and that I really like the overall work environment and my coworkers.
With that being said I have been with my boss almost since the inception of the company and I am the only original employee there. I have seen the company grow from 3 employees including the secretary there. We now have like 20 employees.
I have never complained and I have showed continual growth and loyalty over those 12 years. However, like a month ago they had me post a a job position and it was for a social media position and the job required only 5 years of experience and it was within 8k of what I currently make. That made me so angry.
I am literally capable of doing everyone's job at my job including my own with ease. However, no one else at my job is capable of doing my job at all and I have a bachelors degree as well and certified in many different things as well.
Again I am the most senior person at my job period and the most senior person at the entire company. Not only am I an expert in the programming languages we use at our company, but im an expert at analytics(certified in GA4, looker studio, tag manager, etc).
Additionally, a month ago I was reached out to on linkedin by another company and was offered a job for almost 30 to 40K more than my current job is paying and better benefits than where I currently work and it was fully remote.
Should I even bother asking my boss to match this or should I just walk and go to the other company? Apparently loyalty and knowledge hold no value anymore.5 -
Managed to derive an inverse to karatsuba's multiplication method, converting it into a factorization technique.
Offers a really elegant reason for why non-trivial semiprimes (square free products) are square free.
For a demonstration of karatsubas method, check out:
https://getpocket.com/explore/item/...
Now for the reverse, like I said something elegant emerges.
So we can start by taking the largest digit in our product. Lets say our product is 697.
We find all the digits that produce 6 when summed, along with their order.
thats (1,5), (5,1), (2,4), (4,2), and (3,3)
That means for one of our factors, its largest digit can ONLY be 1, 5, 2, 4, or 3.
Lets take karatsubas method at step f (in the link) and reverse it. Instead of subtracting, we're adding.
If we assume (3,3)
Then we take our middle digit of our product p, in this case the middle digit of 697. is 9, and we munge it with 3.
Then we add our remaining 3, and our remaining unit digit, to get 3+39+7 = 49.
Now, because karatsuba's method ONLY deals with multiplication in single digits, we only need to consider *at most* two digit products.
And interestingly, the only factors of 49 are 7.
49 is a square!
And the only sums that produce 7, are (2,5), (5,2), (3,4), and (4,3)
These would be the possible digits of the factors of 697 if we initially chose (3,3) as our starting point for calculating karatsubas inverse f step.
But you see, 25 can't be a factor of p=697, because 25 is a square, and ends in a 5, so its clearly not prime. 52 can't be either because it ends in 2, likewise 34 ending in 4.
Only 43 could be our possible factor of p.
And we *only* get one factor because our starting point has two of the same digit. Which would mean p would have to equal 43 (a prime) or 1. And because p DOESNT (it equals 697), we can therefore say (3,3) is the wrong starting point, as are ALL starting points that share only one digit, or end in a square.
Ergo we can say the products of non-squares, are specifically non-prime precisely because if they *were* prime, their only factors would HAVE to be themselves, and 1.
For an even BETTER explanation go try karatsuba's method with any prime as the first factor, and 1 as the second factor (just multiply the tens column by zero). And you can see why the inverse, where you might try a starting point that has two matching digits (like 3,3), would obviously fail, because the values it produces could only have two factors; some prime thats not our product, or the value one, which is also not our product.
It's elegant almost to the level of a tautology. -
After years of working at a place where you are as good it gets in terms of domain knowledge, it can be refreshing to work with someone who has way more experience than you.
The previous company I was with wanted to have me as one of their primary engineers, and everyone else who came in would have to learn from me (most of them were low-skilled contractors). This should have been great in theory, but it was actually quite frustrating since I did not relish being the mentor figure while just being two years into my career. Despite it getting to my head at times, I was aware that I still lack a lot of skills, but with no one to teach me, I hardly progressed in terms of growth, even though the leadership treated me well and listened to me.
Took a leap of faith and quit, to join a start-up where I would be the most inexperienced (and the youngest) person. Has been a few months, and I have stumbled and goofed up more times than I like to admit, but taken with the right mindset, it is nice to see how a team of professionals goes about it. It is a learning curve to get back into the mindset of the novice (after more than a year of being the undisputed "go-to" person), and to make effort knowing that you'll fall short in multiple places by the standards here, but at the same time, it's nowhere like the frustration I felt previously when my head was pushing against the shallow ceiling.
Fun part is, the learning is almost not at all about the code, but about how to be a proactive team member and all the things to think through and finalize BEFORE getting down to code. Some of it is bureaucracy, yes, but given the chaotic place I come from, I don't really mind it as long as it only goes as far as what is required.
The most amusing part of it all to me is how I try to be humble and listen to people (everyone's got a lot more experience than me), but I'm often asked to be critical of what others say and poke holes instead of just taking what they say at face value, which has been one of the most challenging things to adapt to for me (for similar organisation cultural reasons mentioned previously)/1 -
So, it's been a while since I've been working on my current project and I've never had the "luck" to touch the legacy project wrote in PHP, until this week when I got my first issue.
And damn, this goddamn issue. It was a bug, a very strange bug, that only happens in production and that nobody has any idea what was happening, so yeah, I didn't have anyone to ask and I got less time than usual ( because Thanksgiving ).
And thus, I have no starting point, no previous knowledge on PHP and less time! I expected a very fun week 😀 and it was beyond my expectations.
First I tried to understand what might be causing the issue, but there wasn't any real clue to star with, so no choice, time to read the flow on the code and see what are they're doing and using ( 1k line files, yay, legacy ). Luckily I got some clues, we're using a cookie and a php session variable for the session, ok, let's star with the session variable. Where it's that been initialize ? Well, spoiler alert, I shouldn't start with that, because my search end up in the login method of the API that set a that variable and for some reason in the front end app it was always false and that lead me to think that some of the new backend functions were failing, but after checking the logs I got no luck.
Ok, maybe the cookie it's the issue, I should try open the previous website on the brow...redirect to new project login, What? Why ? I ask around and it's a new feature push on Monday, ok I got Chrome Dev tools I can see which value of the cookie it's been set and THERE IT WAS it has a wrong domain! After 2 days ( I resume a lot of my pain ) I got what I've been looking for, so now I should be able to fix the bug. Then where is the cookie initialized ? In the first file the server hits whenever you tried to enter any page of the app, ok, I found the method, but it's using a function that process the domain and sets it correctly? wtf ? Then how in heaven do I get the incorrect domain ? Hello? Ok, relax, you still have one more day to fix this, let's take it easy.
Then, at the end of the Wednesday, nope I still have no clue how this is happening. I talked with the Devops guy and he explain me how this redirection happens and with what it depends on, I followed the PHP code through and nothing, everything should works fine, sigh. Ok I still have 2 days, because I'm not from US and I'm not in US, so I still have time, but the Sprint is messed up already, so whatever I'm gonna had done this bug anyhow.
Thursday ! I got sick, yay, what else could happen this week. Somehow I managed to work a little and star thinking in what external issue could affect the processing, maybe the redirection was bringing a wrong direction, let's talk with the Devops guy again, and he answer me that the redirection it was being made by PHP code, IN A FILE THAT DOESN'T EXIST IN THE REPOSITORY, amazing, it's just amazing. Then he explained me why this file might be missing and how it's the deployment of this app ( btw the Devops guy it's really cool and I will invite him a beer ) . After that I checked the file and I see a random session_star in the first line of the code, without any configuration, eureka ! There was the cause and I only need to ask someone If that line it's necessary anymore, but oh they're on holiday, damn, well I'll wait till Monday to ask them. But once and for all that bug was done for ! 🎉
What do I learn ? PHP and that I don't want any more tickets of PHP 😆. -
Incredible that these companies with literally no product, and barely a website (if any) come around offering 100K+ jobs
They have funding out of their ass but literally NO real-world value... it's amazing to me.
Guess it really is not what you can do but who you know.1 -
When me and my friends were working on a school project where we have to do a C++ bus reservation system (that will accept reservation and name of the person who reserved the seat / that will show a list of reserved persons / that will show a graphic design of a bus with seats that will be changed in design if reserved.). At first I can't comprehend the problem and develop a solution, but when my friend told me that "let's think that the value is a poop and the toilet is the variable, when we flush it, it will be sent to the sea/ocean/river and it will serve as a new element in the array" that is when I knew how I will do the damn project, then we passed it the night when the project was given, and we got recognition from our professor.

"Where an expression’s main job is to produce a value, a statement’s job is to produce an effect."
That's the cleanest way of explaining the difference between expressions and statements I've ever seen. Kudos to you, Bob.

I am embrassed.. :(
Situation was..
It was 3-4 months ago I written the process but now client was saying it is not working so I just need to update value in array..
I spent 2-3 hours everything was good..
only in the statement where I am assigning the value is not working.
I was like dude wtf call your senior why its not working .. everything is correct.. then suddenly my eyes catch the rubbish thing I did..
this is what I used mistakenly for assignment "=="
:( and I was looking at statement from 1-2 hour.. it just wasted my time3 -
My college years was actually quite helpful.
I'm from a college that value academic proficiency over industrial skills. There are only 2-3 courses top that are focusing more on coding or software development. The others are theoretical and focus more on the math behinds everything (with fun projects tho, so they are not boring at all).
The importance is that, you could easily learn coding and software dev practice from good examples in your workplace, probably way better what you can get in college. But chances are that our daily job rarely touches hardcore algorithm and mathematical principal behind. Where when you actually need it (bi-weekly scenario), your knowledge and research experience in college comes to play.
And of course, by all means, that was an enjoyable college life! -
hey devs, quick question:
does rust support branchless conditionnals and jump tables, and if yes where to look for syntax?
i found no example for branchless so far and jump tables are scary in rust (and i need a library to use them, it seems).
inb4 "why in the hell/ what possible use those have?!":
i use branchless to make a looping array and jump tables whenever there's more than 4 if statements with equal probability, and the deciding factor is a numeric value, so quite often.27 -
heres something interesting:
The golden ratio is 1.618...
If you're not familiar with it, doing 1/goldenratio
the result is 0.618...
It gives you back the float component exactly.
Discovered that it is actually part of a series.
First of all:
2-(((5-sqrt(5))/2)-1) =
1.618033988749895 -> thats our golden ratio
In other words:
(2%gold) =
0.381966011250106
While:
((5-sqrt(5))/2) =
1.381966011250105
Ok, now we're getting somewhere. We can turn these into variables
First of all, lets see if we can get the golden ratio back out:
2-(((5-sqrt(5))/2)-1) = 1.618033988749895
Okay good.
The formula looks something like
j-(((i-sqrt(i))/2)-1)
Where j = (i*2)+1
That means we can easily figure out what j we need from our i value. (i-1)/2 = j
We run it back far enough we get
1-(((3-sqrt(3))/2)-1) =
1.3660254037844386
Thats the golden ratios little brother. Doesn't look anything like it, but it is part of the series.
And I found a boat load of research documents scattered *all* over the net, where this number and others in the series inexplicably crop up in power series, in chemistry, and elsewhere. Just looks like random floats if you don't know better.
We can actually go lower in the series:
0.5-(((2-sqrt(2))/2)-1)
1.2071067811865475
At the lowest positive value for j, we get
0-(((1-sqrt(1))/2)-1) = 1
It's kinda elegant.
I even wrote a little script to do the conversions:
def gr(k):
....i = k
....j = (i-1)/2
....return j-(((i-sqrt(abs(i)))/2)-1)
The dots are so devrant doesn't break pythons formatting.3 -
So about that job offer (https://devrant.com/rants/3654950/...)
After a weekend of deliberation, I’m going to turn down an offer with a roughly 40% raise to my current salary and the opportunity to work with a language I rly like. Sounds crazy, eh? Maybe it is, too.
However, while the raise woul’ve been great, the job itself sounded interesting enough, and I didn’t think I’d pass on such a chance, I do value my current position, colleagues, the atmosphere at the office, the way - while a little underpaid - we are taken so well care of as employees by our management. It does make for an environment where going to the office and doing your job is a joy.
I think the company I work for rn has more to offer for me, and I have more to offer to them. It’s not my time to jump the ship just yet.3 -
SCW (Secure Code Warrior) IS TOTAL, COMPLETE AND UTTER SHIT!
I keep finding outright and definite mistakes... for example: two solutions that are 100% identical - I copied and diff'd them to be sure I wasn't stoned... the code they show has ZERO comments, so you have ZERO context for anything (and it's written like shit on top of it - I'd fire a motherfucker if they turned in ridiculous crap like this regularly)... I've found answers where one is a subset of another so the "superset" answer should be considered correct as well, so you effectively have two right answers (in other words: this is one of those "you better pick the EXACT answer we WANT you to pick, even if another is TECHNICALLY correct too, doesn't matter, you gotta divine which WE say is right" situations)... there's not enough information given in some cases to even realistically attack the problem... and so on.
It's just fucking garbage, but now I HAVE to get a passing score on the fucking thing to meet a work requirement and you think anyone is going to give two shits if I point out the problems? Of COURSE not! Just need to check the box, so now I have to waste hours of my day fighting through this horseshit just to say I did it.
Is there any value in it? FUCK NO! It's actually NEGATIVE value since now I'm not doing what I'm actually paid to do.
And the worst part is I absolutely, 100% know all this shit! It's not like it's a problem because I fundamentally don't know the concepts. But because your platform is a joke it's making it a nightmare for me.
FUCK THIS SHIT! Friday is over early because of this, I'll bash my head against the wall again on Monday.2 -
Interesting...
On Friday, I was playing with the ChatGPT integration in DBeaver. I was using the DBeaver sample SQLite database. This database has a couple of tables, among them Album and Artist, where Album has a foreign key into Artist.
So, I asked it:
"give me a query that lists all albums from artists who's name starts with s"
The query I got back was:
SELECT * FROM Album
Uhh, okay.
But then, I noticed that I wrote "who's" instead of 'whose', which would be proper grammatically. So, I changed that, and then I got this query:
SELECT * FROM Album WHERE ArtistId IN (SELECT ArtistId FROM Artist WHERE Name LIKE 'S%');
Hooray, that works! I'm not sure it's the best way to write the query... I might have written:
SELECT * FROM album a, artist r WHERE a.artistid=r.artistid AND r.name LIKE 'S%'
...I'd have to check to see if one performs better than the other, and consider which syntax I find clearer, but that's a separate issue, it's just nice to see a working, reasonable query generated because that's the point, after all.
But I found it interesting that such a minor error would cause it to not work, that's my main point.
Interestingly, it seems to have learned: I just tried the same thing, and I got the right query either way. So that's pretty cool.
It's a pretty neat feature and I can see some legitimate value in it. I'm pretty good writing SQL myself... I've managed to write some truly hideously complex queries over the years... but there are definitely instances I can recall where the query didn't seem obvious at the start, and having an AI that can MAYBE produce something that is AT LEAST a starting point is definitely something I can get onboard with.9 -
Hi guys i need to vent with you. I live in Portugal.I graduated in computer science with 16 (0-20). While I was graduating I worked in my university programming for iot and big data fields. I have one article published in a scientific journal. I was looking for a job in my country, and I have gone to 5 interviews where they wanted to pay me about 700 maximum because they say this is my first job. The house rent is about 300 and with food and daily needs I can't have money to simple things in life. It's sad that companies don't give value to people they just think in money. It's sad that our work and knowledge is not valued...7

Possibly my favourite function is Clojure's "recur", which isn't really a function at all, but a special form that gives you a guaranteed tail-position call to the current function.
Basically what that means is you can write recursive functions (functions that call themselves) and know that you're not creating a potential stack overflow.
Um. Okay, I can feel people looking at me like 🤔 Basically what *that* means is: normally when a function calls another function, a "stack frame" is allocated, holding all the local variables for that call. If a function calls itself 1000 times, 1000 stack frames get allocated. "Tail call optimisation" is a process by which if you call yourself as the very last thing in a function, the language doesn't need to remember the current frame; it just has to pass the return value upwards. The trouble is, it's sometimes hard to notice that you've turned a tail-call optimisable function into a non-optimisable one. Clojure's recur keyword makes it explicit, and therefore safe: if you try to do anything with the return value of recur, it's an error.
PS I'm sure another language did explicit TCR first, but Clojure is where I first saw it.6 -
StackOverflow locked my account. I'm hoping someone here might be kind enough to help me with a bash script I'm "bashing" my head with. Actually, it's zsh on MacOS if it makes any difference.
I have an input file. Four lines. No blank lines. Each of the four lines has two strings of text delimited by a tab. Each string on either side of the tab is either one word with no spaces or a bunch of words with spaces. Like this (using <tab> as a placeholder here on Devrant for where the tab actually is)
ABC<tab>DEF
GHI<tab>jkl mno pq
RST<tab>UV
wx<tab>Yz
I need to open and read the file, separate them into key-value pairs, and put them into an array for processing. I have this script to do that:
# Get input arguments
search_string_file="$1"
file_path="$2"
# Read search strings and corresponding names from the file and store in arrays
search_strings=()
search_names=()
# Read search strings and corresponding names from the file and store in arrays
while IFS= read -r line || [[ -n "$line" ]]; do
echo "Line: $line"
search_string=$(echo "$line" | awk -F'\t' '{print $1}')
name=$(echo "$line" | awk -F'\t' '{print $2}')
search_strings+=("$search_string")
search_names+=("$name")
done < "$search_string_file"
# Debug: Print the entire array of search strings
echo "Search strings array:"
for (( i=0; i<${#search_strings[@]}; i++ )); do
echo "[$i] ${search_strings[$i]} -- ${search_names[$i]}"
done
However, in the output, I get the following:
Line: ABC<tab>DEF
Line: GHI<tab>jkl mno pq
Line: RST<tab>UV
Line: wx<tab>Yz
Search strings array:
[0] --
[1] ABC -- DEF
[2] GHI -- jkl mno pq
[3] RST -- UV
That's it. I seem to be off by one because that last line...
Line: wx<tab>Yz
never gets added to the array. What I need it to be is:
[0] ABC -- DEF
[1] GHI -- jkl mno pq
[2] RST -- UV
[3] wx -- Yz
What am I doing wrong here?
Thanks.17 -
Context: This team has been constantly behind on deliveries, ignoring advice from other teams or more experienced colleague, making mistake after mistake and now, just revealed they have major performance issues, as warned...
So, in the most recent Sprint review they were, once again, criticized for their bad approach and inability as a team to receive feedback and work on that feedback, resulting in mediocre development...
As I left the room I heard one of them say:
"We make this huge rocket that most wouldn't be capable of doing and they cry that it's blue and not green... Others make a ls on a command line and everybody applauds"
Now, this is for everyone to whom the shoe fits...
Listen here you little entitled snotty prick, where do you think you are!? Yes most should not make a rocket when the requirement was a bike! That's overengineering and besides that most of your decisions were arguably wrong!
I will never applaud you or anyone else for doing your fucking job and being mediocre about it... What we applaud is value added! Value to the project, to the process or to the team... Bring value and I will applaud, do your job and you get a salary. Be a snotty childish dipshit and you might find yourself forcefully searching for new professional challenge! -
For a new microservice we were designing, I recently had a design discussion with a team member on creating REST endpoints for a new entity. This discussion went on for almost 3 hours, most of the time was spent on why to have two endpoints for getting this resource, one is a POST using a graphQL-like query and another one is a GET using unique ID. I said, the client-side use case is different, one is a dashboard where search results need to be shown based on multiple fields and the unique ID won't be available there because it is a system generated value, second one will be used when the unique ID is present in the client as a result of previous search result. Their responses will be similar, first returns a list of entities, second returns a single entity of the same structure.
Then came the next argument: if both APIs are returning same response, why do we need two different requests ?
It was like saying, because 5+6=11, any sum of two numbers resulting in 11 should always use 5 & 6.
Are people so frustrated of working remotely all the time that they come with such weird arguments ?1 -
Social media site/app... I think social media is such a saturated market yet everyone seems to think their spin is somehow unique and worthwhile...
Although, not sure if DevRant counts as 'social media' but tbh I see real value in getting developers to form a community, where to profit potential comes from potentially linking developers to recruiters/employers (targeted ads to devs for shit we would want). And devs get a nice platform to socialize and bullshit about things we all experience (ie, the 'community' is real and valuable to us)1 -
If not understanding code, read the documentation or debug the code. When trying to modify...
1. Follow proper indentation.
2. Don't make spelling mistakes and follow naming convention.
3. Don't try to write all the code in one line (based on line length set)
4. Simplify if else statements if possible.
5. If value of method call need to be used once, don't store it in a variable. Directly use where ever it is needed.
6. If there is duplicated code, put it in separate method and re-use it if possible.1 -
I start a new job Monday, it feels so great to be out of my old place.
But it also is kinda weird, cause my old job helped get me to where I am now. I along with my brothers and dad were evicted before I started my old job as an intern.
But 6 months into working there and staying with my grandparents, and I got hired full time making $5 more than my dad makes. Me and my dad built up enough savings to own a place. My credit score was higher, and I was working for a title company so my boss gave me a BIG employee discount (this was early into things before I realized how 2-faced she is) if it was my name going onto the mortgage so that's what we did. His savings my credit score and the discount allowed us to get a place 1 bedroom bigger than the old house meaning no more sharing a room with my brother for the first time in my life.
And because of that discount after all was said and done we still had enough in savings to cover rent for a good bit and not have to stress like we did in the last months before we were evicted.
That allowed us to build up savings, start putting more into the mortgage and start paying it down slightly faster, (50 extra a month isn't a lot but it's also not nothing to sneeze at).
I got into the stock market and about a little under a year later i have $150 in unrealized gains gains with a market value of $365 in my stocks.
I also bought a server with the leeway I got from this job and the stability of the new home environment and started toying around with that teaching me I have a major interest in homelab and self hosting which is a part of what helped me get the new job.
This seems like a lot of ramble sorry but it's just weird, 1 job changed my life, and even due to that I couldn't wait to leave it and now that I am I feel kinda regretful at how happy I am to be leaving after how much this job did for me.
But yeah, I couldn't stay another day with my boss. Glad to leave, but also really grateful for everything the job did for me.3 -

last night I had to switch from matrix voice chat to discord voice chat to talk to somebody (because their phone suddenly doesn't do matrix well, keeps cutting out their mic if their screen is turned off or they switch to a different app wtf). they misinterpreted something I said as talking about "shock value". I think that's a demeaning term that doesn't capture why "bad" content is good. now I'm just chilling trying not to workaholic and first recommendation on YouTube I have is about "what happened to shock value websites". oh I'm sure that's a coincidence
this has been happening increasingly and I fucking hate it. it keeps recommending videos that have absolutely nothing to do with what I'm watching or have ever watched or would even be in the interest of in the past, but I mention it somewhere and it creepily suggests the content to me, always with videos claiming to have 2-3 million views. bullshit. I tried some of these and there's no way anybody cares about this content in such numbers. it's so lukewarm and dumb. and how the hell do they have "opinion" vlogs about every topic? since when did that become the #1 type of content on YouTube? cuz it's 50% of my recommendations and I've never given a shit
I have like 500 subscriptions on YouTube. I've had an account a long time. a lot of them are old channels that stopped being active as YouTube evolved, which I think was a shame. a lot of them had to do with ad revenue or YouTube algorithm just not suggesting their content to new people. they were wholesome, honest channels with really good content I think -- really good game analysis, compilations of unique or weird viral content and the guy was just a funny dude in his basement, etc. but fair I guess. shame, but fair
Then there was the quiet era, where your front page just didn't suggest the good channels and just the stupid channels. it didn't suggest your subscriptions but in your interest area or something. what's the point of subscriptions if you're not showing me them? this is also about the time if I left a comment on a video I ceased receiving replies so I assume I was shadow banned. I have not received a single reply in years now, even on small channels. some content creators noticed if they post on their own channels and accidentally logged out and looked for their comment their own comments don't show up. just weird annoying nonsense that's inappropriate for them to be doing. bruh, please
and then the next wave came, it wasn't just YouTube won't recommend your channel, in the COVID era what came was if you mentioned something then channels with previously millions of views, still currently millions of subscribers, suddenly went down to 5k-50k views per video. bitch please, you expect anyone to believe this nonsense?
then they fucked up the search. I KNOW videos exist and I can't find them. I type in half the video's title, you can't find it. thankfully if you type in every single word exactly you can still find them. bruh that's too much. also just search plain doesn't work. if I'm looking for a specific topic I get 5-10 max videos on that topic and the rest are irrelevant recommendations. this is entirely ridiculous. there's videos I KNOW exist on YouTube and nobody gave a shit about them, like 5 view Benny benassi music clips with a scene from a video game. I can't even meme anymore
this morning a friend on discord sent me a... weird clip, of like an anime skit. problem? well discord embeds YouTube videos. I pressed play. I get... an ad. lol what. I browse away and back to the video. try again. ad. yeah I'm not playing this. I have to refresh the page 20-30 times sometimes just until the ads stop fucking up every time my adblocker ceases working (and then I have to go update it again lol -- by going to the developer page for the ad block because it was banned from the app store so you can't auto update it and have to manually update it every time)
my friend links me a discord plugin to... remove ads... from YouTube embeds... bruh
I used to mod discord but it's annoying, because every time discord updates you have to go re-apply the hack to be able to mod your discord
I think we should just plain move away from YouTube. during COVID era a lot of people got banned in subreddits on reddit. I noticed when you get banned, the subreddit still has you listed as a subscriber. the r/Canada subreddit for example has 3 million subscribers but the activity of a subreddit that's maybe 1k people. increasingly subreddits just became ghost towns after that like that. reddit is a dead website, with fake numbers. I think YouTube is now a dead website, with fake numbers. no fucking way stupid lukewarm opinion videos with absolutely nothing to add are getting 2-3 million views and people are just clamouring for these takes they didn't ask for
also stop listening in on my private conversations. fucking disgusting. idc if an AI is transcribing. ew.11 -
So, I have a nested ternary, right, and that's not very readable:
(x <= y ? z : (x <= z ? y : x));
The linter points this out and I'm like yeah, valid point. So I inline-F[*0] it:
if (x <= y)
········return z;
else if (x <= z)
········return y;
else
········return x;
Clearer? Kinda. Oh, but the linter doesn't like this either, and to be fair, valid point once again; an else-after-return *can* be quite confusing if you have it in the __middle__ of the F body, catches you by suprise.
However, I'd like to take a brief moment to waggle your nutsack, if you please. Because this is C++ and I'm picking a reference from a list of values, so I can't simply assout[*1] within the switch.
So I'm at the crossroads of life once again, losing man's toughest struggle as I sit on a metaphorical cigar, squirming while I unclench my asshole slowly for strictly defecatory purposes. Allow me to illustrate:
- If I ignore the linter, and leave the rest of the code unchanged, the checks are going to fail and the bot is going to taint my pristine PR with automated comments.
- But if I take the linter's advice, I have to do a slight rewrite of the damn thing plus every F that calls it, which means touching shit that has nothing to do with this issue.
So what's it gonna be? Flushing or shoving my own excrement? Oh, the thrills of it being (literally) SOLID, ie not the acronym, but may the Almighty punish Uncle Bob regardless.
NOTES:
[*0]: It means 'function,' what else?
[*1]: ASS-ign OUT-put, where 'out' is just some var. You modify the var within the F body and return the final value.16 -
I was asked to revisit some code yesterday - code that I had written at a much better time in my life. I was productive, I was on top of my project and we were delivering value to the organization.
I'm at a point now where I haven't written any code for months. I've been documenting and designing and arguing with teammates over inane shit. It's been an absolute slog, and I've started looking at what it would take for me to actually quit since I've got a kid on the way, and I've been bringing the stress and anxiety home from work. I've got so much money in options and salary, it's basically impossible for me to leave for better work.
I'd consider this the lowest point in my professional career. Four years of college - where I beat alcoholism and depression (mostly) only to end up at a place that I fucking hate, but cannot leave. It's affecting my family. I've drank more in the past 6 months than I have in my entire life.
And now I have to start repurposing old code to work on a new project that is fucked up 5 ways from Sunday. I honestly don't know how much further I can stretch my professional ethics to keep this shitload of cash flowing into my savings.3 -
Heres some research into a new LLM architecture I recently built and have had actual success with.
The idea is simple, you do the standard thing of generating random vectors for your dictionary of tokens, we'll call these numbers your 'weights'. Then, for whatever sentence you want to use as input, you generate a context embedding by looking up those tokens, and putting them into a list.
Next, you do the same for the output you want to map to, lets call it the decoder embedding.
You then loop, and generate a 'noise embedding', for each vector or individual token in the context embedding, you then subtract that token's noise value from that token's embedding value or specific weight.
You find the weight index in the weight dictionary (one entry per word or token in your token dictionary) thats closest to this embedding. You use a version of cuckoo hashing where similar values are stored near each other, and the canonical weight values are actually the key of each key:value pair in your token dictionary. When doing this you align all random numbered keys in the dictionary (a uniform sample from 0 to 1), and look at hamming distance between the context embedding+noise embedding (called the encoder embedding) versus the canonical keys, with each digit from left to right being penalized by some factor f (because numbers further left are larger magnitudes), and then penalize or reward based on the numeric closeness of any given individual digit of the encoder embedding at the same index of any given weight i.
You then substitute the canonical weight in place of this encoder embedding, look up that weights index in my earliest version, and then use that index to lookup the word|token in the token dictionary and compare it to the word at the current index of the training output to match against.
Of course by switching to the hash version the lookup is significantly faster, but I digress.
That introduces a problem.
If each input token matches one output token how do we get variable length outputs, how do we do n-to-m mappings of input and output?
One of the things I explored was using pseudo-markovian processes, where theres one node, A, with two links to itself, B, and C.
B is a transition matrix, and A holds its own state. At any given timestep, A may use either the default transition matrix (training data encoder embeddings) with B, or it may generate new ones, using C and a context window of A's prior states.
C can be used to modify A, or it can be used to as a noise embedding to modify B.
A can take on the state of both A and C or A and B. In fact we do both, and measure which is closest to the correct output during training.
What this *doesn't* do is give us variable length encodings or decodings.
So I thought a while and said, if we're using noise embeddings, why can't we use multiple?
And if we're doing multiple, what if we used a middle layer, lets call it the 'key', and took its mean
over *many* training examples, and used it to map from the variance of an input (query) to the variance and mean of
a training or inference output (value).
But how does that tell us when to stop or continue generating tokens for the output?
Posted on pastebin if you want to read the whole thing (DR wouldn't post for some reason).
In any case I wasn't sure if I was dreaming or if I was off in left field, so I went and built the damn thing, the autoencoder part, wasn't even sure I could, but I did, and it just works. I'm still scratching my head.

YGGG IM SO CLOSE I CAN ALMOST TASTE IT.
Register allocation pretty much done: you can still juggle registers manually if you want, but you don't have to -- declaring a variable and using it as operand instead of a register is implicitly telling the compiler to handle it for you.
Whats more, spilling to stack is done automatically, keeping track of whether a value is or isnt required so its only done when absolutely necessary. And variables are handled differently depending on wheter they are input, output, or both, so we can eliminate making redundant copies in some cases.
Its a thing of beauty, defenestrating the difficult aspects of assembly, while still writting pure assembly... well, for the most part. There's some C-like sugar that's just too convenient for me not to include.
(x,y)=*F arg0,argN. This piece of shit is the distillation of my very profound meditations on fuckerous thoughtlessness, so let me break it down:
- (x,y)=; fuck you in the ass I can return as many values as I want. You dont need the parens if theres only a single return.
- *F args; some may have thought I was dereferencing a pointer but Im calling F and passing it arguments; the asterisk indicates I want to jump to a symbol rather than read its address or the value stored at it.
To the virtual machine, this is three instructions:
- bind x,y; overwrite these values with Fs output.
- pass arg0,argN; setup the damn parameters.
- call F; you know this one, so perform the deed.
Everything else is generated; these are macro-instructions with some logic attached to them, and theres a step in the compilation dedicated to walking the stupid program for the seventh fucking time that handles the expansion and optimization.
So whats left? Ah shit, classes. Disinfect and open wide mother fucker we're doing OOP without a condom.
Now, obviously, we have to sanitize a lot of what OOP stands for. In general, you can consider every textbook shit, so much so that wiping your ass with their pages would defeat the point of wiping your ass.
Lets say, for simplicity, that every program is a data transform (see: computation) broken down into a multitude of classes that represent the layout and quantity of memory required at different steps, plus the operations performed on said memory.
That is most if not all of the paradigm's merit right there. Everything else that I thought to have found use for was in the end nothing but deranged ways of deriving one thing from another. Telling you I want the size of this worth of space is such an act, and is indeed useful; telling you I want to utilize this as base for that when this itself cannot be directly used is theoretically a poorly worded and overly verbose bitch slap.
Plainly, fucktoys and abstract classes are a mistake, autocorrect these fucking misspelled testicle sax.
None of the remaining deeper lore, or rather sleazy fanfiction, that forms the larger cannon of object oriented as taught by my colleagues makes sufficient sense at this level for me to even consider dumping a steaming fat shit down it's execrable throat, and so I will spare you bearing witness to the inevitable forced coprophagia.
This is what we're left with: structures and procedures. Easy as gobblin pie.
Any F taking pointer-to-struc as it's first argument that is declared within the same namespace can be fetched by an instance of the structure in question. The sugar: x ->* F arg0,argN
Where ->* stands for failed abortion. No, the arrow by itself means fetch me a symbol; the asterisk wants to jump there. So fetch and do. We make it work for all symbols just to be dicks about it.
Anyway, invoking anything like this passes the caller to the callee. If you use the name of the struc rather than a pointer, you get it as a string. Because fuck you, I like Perl.
What else is there to discuss? My mind seems blank, but it is truly blank.
Allocating multitudes of structures, with same or different types, should be done in one go whenever possible. I know I want to do this, and I know whichever way we settle for has to be intuitive, else this entire project has failed.
So my version of new always takes an argument, dont you just love slurping diarrhea. If zero it means call malloc for this one, else it's an address where this instance is to be stored.
What's the big idea? Only the topmost instance in any given hierarchy will trigger an allocation. My compiler could easily perform this analysis because I am unemployed.
So where do you want it on the stack on the heap yyou want to reutilize any piece of ass, where buttocks stands for some adequately sized space in memory -- entirely within the realm of possibility. Furthermore, evicting shit you don't need and replacing it with something else.
Let me tell you, I will give your every object an allocator if you give the chance. I will -- nevermind. This is not for your orifices, porridges, oranges, morpheousness.

I have found that once you work for a company where you have to implement everything in its raw form using the raw language and raw logic, you really have to know what you're doing and knowing some basic/medium programming and having some algebra knowledge doesn't cut it (unlike some people think).
I've been at two sides of the coin: I worked for a company that had everything in place, a framework that handled all edge cases and what not and I just had to focus on user stories, but I also worked for a company where I had to do everything manually.
For example, at the latter company I had to know Discrete Mathematics; truth tables to their most convoluted and disgusting form, having to be able to apply this on a late Friday night with a headache and lack of food and sleep with the PM stressing out.
I've had to deal with NOT AND OR AND OR AND OR AND branches or whatever, where an OR behaves like an AND and if you want a value between an AND AND and an OR, you'd have to do a NOT OR.. to think about latches, all in my head, sigh, anyway, within limited time constraints, without even having time to write tests, having to make sure that everything checks out while the client is breathing down my neck. Yeah, not such fun times.
I'm happy for those of you who can just write some moderately difficult logic but you don't have to break your head over doing everything manually, as if you're in the coding stone age and nothing is taken care of.
Companies like these make me want to run away.3 -
is being a tech/dev person, a dead end job?
i have been thinking about this for sometime. as a dev, we can progress into senior dev, then tech lead, then staff engineer probably. but that is that. for a tech person :
1. their salary levels are defined. for eg, a junior may earn $10k pm , and the highest tech guy (say staff engineer) will earn $100k pm, but everyone's salary will be spread over this range only, in different slots.
2. some companies give stocks and bonuses , but most of the time that too is fixed to say 30% of the annual salary at max.
3. its a low risk job as a min of x number of tech folks are always required for their tech product to work properly. plus these folks are majorly with similar skills, so 2 react guys can be reduced to 1 but not because of incompetency .
4. even if people are incompetent, our domain is friendly and more like a community learning stuff. we share our knowledge in public domain and try to make things easy to learn for other folks inside and outside the office. this is probably a bad thing too
compare this to businesses , management and sales they have different:
1. thier career progression : saleman > sales team manager> branch manager > multiple branch manager(director) > multiple zones/state manager (president) > multiple countries/ company manager (cxo)
2. their salaries are comission based. they get a commission in the number of sales they get, later theybget comission in the sales of their team> their branch > their zone and finally in company's total revenue. this leads to very meagre number in salaries, but a very major and mostly consistent and handsome number in commission. that is why their salaries ranges from $2k pm to $2-$3millions per month.
3. in sales/management , their is a always a room for optimisation . if a guy is selling less products, than another guy, he could be fired and leads could be given to other/new person. managers can optimise the cost/expenses chain and help company generate wider profits. overall everyone is running for (a) to get an incentive and (b) to dodge their boss's axe.
4. this makes it a cut-throat and a network-first domain. people are arrogant and selfish, and have their own special tricks and tactics to ensure their value.
as a manager , you don't go around sharing the stories on how you got apple to partner with foxconn for every iphone manufacturing, you just enjoy the big fat bonus check and awe of inspiration that your junior interns make.
this sound a little bad , but on the contrary , this involves being a people person and a social animal. i remember one example from the office web series, where different sales people would have different strategies for getting a business: Michael would go wild, Stanley would connect with people of his race, and Phyllis would dress up like a client's wife.
in real life too, i have seen people using various social cues to get business. the guy from whom we bought our car, he was so friendly with my dad, i once thought that they are some long lost brothers.
this makes me wonder : are sales/mgmt people being better at being entrepreneur and human beings than we devs?
in terms of ethics, i don't think that people who are defining their life around comissions and cut throat races to be friendly or supportive beings. but at the same time, they would be connecting with people and their real problems, so they might become more helpful than their friends/relatives and other "good people" ?
Additionally, the skills of sales/mgmt translate directly to entrepreneurship, so every good salesman/manager is a billionaire in making. whereas we devs are just being peas in a pod , debating on next big npm package and trying to manage taxes on our already meagre , "consistent" income :/
mann i want some people skills like these guys10 -
Our owner's other company sells products online (or has the ability to anyways). Their current site is 7+ years old WordPress/Woocommerce and is seriously outdated because the site breaks if you update anything so we've been told to make a new site (finally). They also said they were going to release a whole new line up of products. So the first thing I tried to do was get them to nail down their product line and how shipping was going to be configured. I was told to just use the shipping from the previous site.
Turns out those shipping rates don't use any sort of math or automation at all, there is literally a manually set shipping value for every single product for every single shipping location (30*60) and even values for different quantities. And there's no way to export these rates into a readable table because the plugins they use shove all the data into the postmeta table, I'm forced to go through and put the data into a spreadsheet so that I can attempt to organize it and hopefully find someone way to automate it. Owner claims at one point that he has a similar spreadsheet that's more up to date but for some reason refuses to send it over or put me in touch with the right people in the shipping department.
I've gone through the shipping rates with the old products and the new products and organized them as best I can and each time I've gotten done and shown them the spreadsheet with their products and shipping, they add or change something which requires me to basically wipe the slate clean and start over eating another 50 or so hours of my time, which with everything else really means another month+ to find time to work on it between other projects.
After about a year they finished their products and I finally finished the planning and got approval to build it out for the site. Small victory!!
After about 60 hours plugging these values into the database (only about 1/3 done) I get an email from their head of shipping who tells me the values in my spreadsheet are "terribly inaccurate, in some areas by $100+" and that the data should not be used anywhere.
So after something like a year and a half and 200+ hours of work, the data I've been using to plan all this isn't even accurate. I'm trying not to go crazy here but this kind of shit is unacceptable. When we're done with this I'm going to send the owner an invoice to show him how much money he wasted on this because nothing was planned and he just wanted it built. There's a fucking process for a reason, when you don't follow the process you fuck everything up. If a client had pulled this shit and turned their simple site into this much work they would have been dropped. I get constant emails asking when the new site will be done and every time my answer is "I'm still waiting for x items that I asked for last time you asked where we were." He gets a couple things on the list and sends them back and then goes unresponsive for weeks at a time.
Management has been telling me that I seem more stressed lately but only one of them understands what's going on here when I explain it. The rest say stupid shit like "why don't you automate it" or "make an intern do it." You won't let me hire an intern and even if I did, I'm not sure I could explain how the shipping works now to even trust someone else to do it. I'm hoping when the shipping guy gives me the new sheet that maybe there's some easier solution here because I'm ready to start shooting people.2 -
Can anyone help me with this theory about microprocessor, cpu and computers in general?
( I used to love programming when during school days when it was just basic searching/sorting and oop. Even in college , when it advanced to language details , compilers and data structures, i was fine. But subjects like coa and microprocessors, which kind of explains the working of hardware behind the brain that is a computer is so difficult to understand for me 😭😭😭)
How a computer works? All i knew was that when a bulb gets connected to a battery via wires, some metal inside it starts glowing and we see light. No magics involved till now.
Then came the von Neumann architecture which says a computer consists of 4 things : i/o devices, system bus ,memory and cpu. I/0 and memory interact with system bus, which is controlled by cpu . Thus cpu controls everything and that's how computer works.
Wait, what?
Let's take an easy example of calc. i pressed 1+2= on keyboard, it showed me '1+2=' and then '3'. How the hell that hapenned ?
Then some video told me this : every key in your keyboard is connected to a multiplexer which gives a special "code" to the processer regarding the key press.
The "control unit" of cpu commands the ram to store every character until '=' is pressed (which is a kind of interrupt telling the cpu to start processing) . RAM is simply a bunch of storage circuits (which can store some 1s) along with another bunch of circuits which can retrieve these data.
Up till now, the control unit knows that memory has (for eg):
Value 1 stored as 0001 at some address 34A
Value + stored as 11001101 at some address 34B
Value 2 stored as 0010 at some Address 23B
On recieving code for '=' press, the "control unit" commands the "alu" unit of cpu to fectch data from memory , understand it and calculate the result(i e the "fetch, decode and execute" cycle)
Alu fetches the "codes" from the memory, which translates to ADD 34A,23B i.e add the data stored at addresses 34a , 23b. The alu retrieves values present at given addresses, passes them through its adder circuit and puts the result at some new address 21H.
The control unit then fetches this result from new address and via, system busses, sends this new value to display's memory loaded at some memory port 4044.
The display picks it up and instantly shows it.
My problems:
1. Is this all correct? Does this only happens?
2. Please expand this more.
How is this system bus, alu, cpu , working?
What are the registers, accumulators , flip flops in the memory?
What are the machine cycles?
What are instructions cycles , opcodes, instruction codes ?
Where does assembly language comes in?
How does cpu manipulates memory?
This data bus , control bus, what are they?
I have come across so many weird words i dont understand dma, interrupts , memory mapped i/o devices, etc. Somebody please explain.
Ps : am learning about the fucking 8085 microprocessor in class and i can't even relate to basic computer architecture. I had flunked the coa paper which i now realise why, coz its so confusing. :'''(14 -
I'm a Ruby on Rails developer. I love Rails because you can get so much done so quickly. I've built huge websites on Rails at the consultant shop where I work.
A couple of years ago we added a frontend guy to the team. We switched from doing full stack Rails to using Rails for API only with Vue with Typescript as the frontend. Since this transition took place, I am unable to get anything done on frontend. It takes a huge amount of effort to just add a new input box to a page. Our whole team is on the edge of getting laid off because we can't get things done in a timely fashion for clients and our products consistently run over time and over budget.
Here I'm trying to add an "Are you sure you want to delete this?" message to a form, and I'm on third hour trying to make Typescript happy. I want to assign a variable a value and I have to decipher errors like this "Type 'Ref<string>' is missing the following properties from type 'Vue<string, Record<string, any>, never, never, (event: string, ...args: any[]) => Vue<Record<string, any>, Record<string, any>, never, never, ...>>': $data, $props, $parent, $root, and 30 more." WTF?!?!
Am I just not smart enough for this? Why did programming suddenly become so hard for me? If I had to start off this way I wouldn't be a programmer because I wouldn't have been able to figure this out alone and it wouldn't have been any fun. Anyone else have the HATE for Typescript that I do?10 -
My team was asked to point to a mock service in our QA env. Standard procedure is to copy the line in our QA property file that has the service URL, comment one out, and change the other to the mock service. Then, push the code and deploy to QA.
What did someone do? He didn't touch the property file. He found where we were defining the configuration for our http requester, removed the property reference, and HARD CODED the mock URL.
Wait, it gets better. The mock service does not function the same way the real service does. We need to send an additional query param to the mock service (that has a value already being sent in a header) so they modified ANOTHER file where the actual request is being made.
He made the changes, deployed to QA, and didn't check in any code.
What is going to happen next time when we deploy to QA with the latest code? Oh look, we'll be pointing to the real service again.
I explained this to my architect, and included that this messed up mock service they were calling is our 2nd mock service (no idea why they made a new one) and he simply deleted the stupid 2nd mock service. Screw that!
And...now requests to QA don't work 😂 -
I had to optimize a SQL-Query and i was able to cut the amount of time in half.
The business part of the company said it is still too slow, so i researched deeper and looked into the called functions which are used in every part where to claculate value X.
Found 20 similiar selects to get values which are summed up afterwards into three different variables. Thought this can be done in three selects with "sum", but then i found the dumbest thing is this function:
V1, V2 have the values from the selects
V3 is ja given value
X is the return value
the function returns another value
help = functionCall(parameter) - V1 -V2
X= help + V1 + V2 +V3
WTF im mean it does the selects for nothing...
X = functionCall(parameter) + V3 -
I'm a self-taught frontend developer with 1,5 - 2 years of experience in JavaScript / Vue.js development. Pretty cliche in 2023 and I can actually feel this now when it comes to the job market. It's brutal at the moment.I moved to Germany for a specific job but got laid off a few weeks ago due to a lack of projects and actual things to do. And here I am right now: tons of job applications, 4-5 interviews a week, zero success.
I'm thinking about getting some warehouse job or anything for the time being, and start freelancing in my spare time. Instead of this oversaturated JavaScript landscape, I would get into PHP (not as "hip" so less competition, backend, no new tools every 6 months), SQL, or hyper-specialize in CSS - something I like quite a bit but have seemingly zero value to employers.
I actually made a simple website for a small business when I was getting started with frontend, and he was super happy with the end result. I also did some language tutoring, that was quite rewarding as well. So freelancing is definitely fun, I enjoyed it much more than fearing layoffs or trying to force a fake-ambitious attitude on my 30th interview that most probably won't lead me anywhere. :D
Is the frontend job market really this oversaturated? (I know, I know... It's not difficult for competent, skilled, and experienced devs with CS degrees) Is being a CSS specialist, PHP-developer, or SQL-magician on fiverr/upwork/etc. a viable freelancing path? I've heard good and bad about these platforms, the competition there, etc. If not, where should I start?
What do you think? Any input is much appreciated. :)4 -
This is probably a standard pattern/algorithm, but I feel pretty good about myself figuring this out.
I was doing a programming challenge and found myself with 2 lists of integer points (x,y). I needed to see where the points converged and identify those locations. Of course I started with a brute force approach and did nested loops to find these locations. This was taking WAY TOO LONG. These lists were 200K each. So checking with naive looping is 200K * 200K operations. Which is a lot.
Then I thought, well I am checking equality, so I will create a third map. The index to the map will be the point, and the data will be an integer. I then go through each list once incrementing the integer for each point that exists in each respective list. Any point with a value greater than 1 is a point convergence.
Like I said, this has got to be a standard thing, so can someone tell me what algorithm this is? I am not sure how to search for this.
I am fuzzy on complexity notation but I think the complexity started at n^2 and was reduced to n. Each list is cycled over once.4 -
There were many issues that came about during my entire employment, but I woke up today with some, honestly, quite bizarre questions from my manager that made me open an account here. This is just the latest in many frustrations I have had.
For context, my manager is more of a "tech lead" who maintains a few projects, the number can probably be counted in one hand. So he does have the knowledge to make changes when needed.
A few weeks ago, I was asked to develop a utility tool to retrieve users from Active Directory and insert them into a MSSQL Database, pretty straight forward and there were no other requirements.
I developed it, tested it, pushed it to our repository, then deployed the latest build to the server that had Active Directory, told my manager that I had done so and left it at that.
A few weeks later,
Manager: "Can you update the tool to now support inserting to both MSSQL and MySQL?"
Me: "Sure." (Would've been nice to know that beforehand since I'm already working on something else but I understand that maybe it wasn't in the original scope)
I do that and redeploy it, even wrote documentation explaining what it did and how it worked. And as per his request, a technical documentation as well that explains more in depth how it works. The documents were uploaded as well.
A few days after I have done so,
Manager: "Can you send me the built program with the documentation directly?"
I said nothing and just did as he asked even though I know he could've just retrieved it himself considering I've uploaded and deployed them all.
This morning,
Manager: "When I click on this thing, I receive this error."
Me: "Where are you running the tool?"
Manager: "My own laptop."
Me: "Does your laptop have Active Directory?"
Manager: "Nope, but I am connected to the server with Active Directory."
Me: "Well the tool can only retrieve Active Directory information on a PC with it."
Manager: "Oh you mean it has to run on the PC with Active Directory?"
Me: "Yeah?"
Manager: "Alright. Also, what is the valid value for this configuration? You mentioned it is the Database connection string."
After that I just gave up and stopped responding. Not long after, he sent me a screenshot of the configuration file where he finally figured out what to put in.
A few minutes later,
Manager: "Got this error." And sends a screenshot that tells you what the error is.
Me: "The connection string you set is pointing to the wrong database schema."
Manager: "Oh whoops. Now it works. Anyway, what are these attribute values you retrieve from Active Directory? Also, what is the method you used to connect/query/retrieve the users? I need to document it down for the higher ups."
Me: "The values are the username, name and email? And as mentioned in the technical documentation, it's retrieving using this method."
The 2+ years I have been working with this company has been some of the most frustrating in my entire life. But thankfully, this is the final month I will be working with them.21 -
Questions that are bothering me:
When a function that returns void returns, is any value from the stack frame copied into the register?
Is the return address in the stack frame even allocated, or is it nullptr?
Could a void function theoretically return a value if you hacked one into the frame?
Does the register even know to expect a value from a void function? If so, where is the logic for this and what is difference between a void and non-void function return at the stack frame & register level?
Any good books on this stuff?2 -
Is it just me, or is form autofill in the browser just a major PITA for shop owners when people get to the checkout screen? I've had two clients in the past week with problems where users didn't pay attention to their autofill outcomes, or where the form absolutely has to keep a certain value that we've autofilled for them but gets overwritten by their browser. Now there is a shipment of product out in the wind that is going to return to sender and be delayed in a correction cycle. If you've been able to halt this type of nonsense, I'd love to know how you did it.

I see a lot of people ranting about programming exams on paper. I acknowledged that not having a texteditor is not ideal. But not having a compiler is essential in testing the students programming skills in the first few courses.To many students are completely dependent on the compiler.
Syntax:
Some students writing C++ code have to try to build their program as many times they have lines because of all the syntax errors they make. Why think about all the ; if your compiler will tell you where they are missing?
Computational thinking:
As a programmer you should be able to look at (your own) code and be able to tell what the result should be. Of course this has its limits, but in the small exam questions they get in the first few courses they should be able to do that. To many first year students write a for loop without thinking about the starting value and the end condition. With the repeated process of running the program, changing the starting value or the end condition randomly they eventually get to the loop they need.
I think people underestimate the value of an exam without being able to compile or run your program. But I like to hear your reactions. -
Can somebody explain to me why developers (especially web) have to micromanage every single thing into it's own f*ing component.
Story time: I have an input form with some tabs. I discovered that the UI Library (Devextreme) has a nice little component that handles forms, (including tabs, groups, etc.). So I make a page, configure tabs, inputs and whatnot.
Now, I already knew that my coworkers can't handle html that is bigger than a page. So instead of putting the configs in the frontend, I made nice files where I store those, to keep them nicely clean and seperated.
Me feeling very good, went off to have a nice lunch break.
I come back read the message from my coworker, asking me to make every tab it's own component and form and load them into a separate Tab-Component, instead of using the built in configuration
......
WHAT?
Like seriously. I have a f*ing library that handles that, why the f*ck do I need to reinvent the wheel here!?
Supposedly it's to make it more maintainable, easier to find bugs, flatten the hierarchy.
Here's a little wake up call you morons: Nesting hundreds of components into each other does *not* help you with that.
It just creates a rabbit-hole of confusing containers that you have to navigate and dissect every time you try to find something.
"Can I fix the bug in the detail Page? Sure I'll tell you tomorrow when I find out which fucking component the bug results from".
Components are there to be *reused*. It's using inheritance for reusing code all over again, but worse.
But maybe I'm just old fashioned, and conservative. Maybe I'm just a really bad software engineer, because nowadays everything seems to result in architectures spreading hundreds of folders, thousands of files with nothing but arbitrary cut-offs with no real benefit, that I don't see the value in.6 -
A bit longer rant, somehow triggered by the end of this rant:
https://devrant.com/rants/7145365/...
The discussion revolved around strpos returning false or a positive integer.
Instead of an Option or a Exception.
I said I'm a sucker for exception, but I'm also a sucker for typing.
Which is something most languages lack - except the lower level ones like C / C++.
I always loved languages which have unsigned and signed types.
There, I said it... :) I know that signed / unsigned is controversial, Google immediately leads to blog entries screaming bloody murder because unsigned can overflow – or underflow, if someone tries to use a -1on an unsigned integer.
Note that my love is only meant for numeric types, unsigned / signed char is ... a whole can of insanity on its own.
https://phoronix.com/news/...
If you wanna know more.
Back to the strpos problem, now with my secret love exposed:
strpos works on a single string, where a string is a sequence of chars starting with 0.
0 is a positive integer.
In case the needle (char that should be looked up in the string) cannot be found in the haystack (the string), PHP returns "false".
This leads to the necessity of explicitly checking the type as "0" (beginning of string, a string position)... So strpos !== false.
PHP interprets 0 as false, any other integer value is true.
In the discussion, the suggestion came up to return -1 if a value could not be found – which some languages do, for example Scala.
Now I said I have a love for unsigned & signed integers vs. just signed integers...
Can you guess why the -1 bothers me very much?
Because it's a value that's illogical.
A search in a sequence that is indexed by 0 can only have 0 or more elements, not less than zero elements.
-1 refers to a position in the sequence that *cannot* exist.
Which is - of course - the reason -1 was chosen as a return value for false, but it still annoys me.
An unsigned integer with an exception would be my love as a return value, mostly because an unsigned integer represents the return value *best*. After all, the sequence can only return a value of 0 ... X.
*sigh*
Yes, I know I'm weird.
I'm also missing unsigned in Postgres, which was more or less not implemented because it's not in the SQL standard...

I recently went through a very detailed and well-explained Python-based project/lesson by Karpathy which is called micrograd. This is a tiny scalar-valued autograd engine and a neural net on top of it.
The project above is, as expected, built on Python. For learning purposes, I wanted to see how such a network may be implemented in TypeScript and came up with a 🤖 micrograd-ts - https://github.com/trekhleb/... repository (and also with a demo - https://trekhleb.dev/micrograd-ts/ of how the network may be trained).
Trying to build anything on your own very often gives you a much better understanding of a topic. So, this was a good exercise, especially taking into account that the whole code is just ~200 lines of TS code with no external dependencies.
The micrograd-ts repository might be useful for those who want to get a basic understanding of how neural networks work, using a TypeScript environment for experimentation.
With that being said, let me give you some more information about the project.
## Project structure
- [micrograd/](https://github.com/trekhleb/...) — this folder is the core/purpose of the repo
- [engine.ts](https://github.com/trekhleb/...) — the scalar `Value` class that supports basic math operations like `add`, `sub`, `div`, `mul`, `pow`, `exp`, `tanh` and has a `backward()` method that calculates a derivative of the expression, which is required for back-propagation flow.
- [nn.ts](https://github.com/trekhleb/...) — the `Neuron`, `Layer`, and `MLP` (multi-layer perceptron) classes that implement a neural network on top of the differentiable scalar `Values`.
- [demo/](https://github.com/trekhleb/...) - demo React application to experiment with the micrograd code
- [src/demos/](https://github.com/trekhleb/...) - several playgrounds where you can experiment with the `Neuron`, `Layer`, and `MLP` classes.
Demo (online)

I'm studying Databases and I'm getting confused about Foreign Key.
A Foreign Key made reference to Primary Key of another table. But what's the point? Can't I simply use a value and select requested data where TableA value is equal to TableB value?
Sorry if I didn't explain it well, I'm so confused lmao6 -
React Native testing is hair pulling.
Every test needs to have 100 different mocks in place and there are: 3 different methods to mock a function (mock, mockImplementation, and fn), 3 different types of query methods to get elements (get, find, and query), and 5 different selectors to query on (accessibility label, testId, accessibility hint, accessibility value, etc.)
And after reading all this, being diligent and learning the difference between stupid, synonymously-named functions which have wildly different side effects like "getByA11yHint" and "findByA11yHint" (ugh...), after all that, you write out a test with all the appropriate mocks and you want to do something simple and it beats you up all over again.
Button enabled or button disabled. Simple right? Logically the former is "expect(elem).toBeEnabled()" and the latter is "expect(elem).not.toBeEnabled()", right?
Wrong! You're an imbecile. Your tests will fail and never tell you that ".not.toBeEnabled()" and ".toBeDisabled()" don't do the same thing even though they look and sound exactly the same. Only the latter will work. The former makes all your tests fail. Where is this written in the docs? Nowhere?! Great!

So first rant, here goes weirdness, and also lengthy rant
So in my company we have the hr and accounting managed by the same person which also deals with all things employee related and she had a need for a way to extract a birthday from, what is in our country the personal identification number, things go great i get a formula that performs parts of the magic up to the point where the first digit of the number dictates the gender and century to be used when forming the full year, mind you only the last two digits of the year are in plain within the id number so i thy a number of ideas. After bashing around google sheets for a while ( i've got open office installed and formulas don't export well to the excel that person uses but google sheets does so i built it there).
First idea : make a few conditionals to check for the value so we have 1 and 2 for 19th century, 3 and 4 for 18th century , 5 and 6 for 20th so i go ahead and write my conditions and they fail, all evaluates to false, it cascades through the else variants up to the last one so i'm wondering if the "if" itself doesn't support the or operator, seems it does, next i think it's the bloody condition written wrong so i reevaluate my logic in php in a test script, it works as intended, then i think ok not the right function called, let's see the docs, docs confirm i'm doing it right but what was wrong was the way i was getting that first number, using left seems to produce a string although the base thing is a number, now i start searching how i can cast it, like you would normaly do when the data type is fried, value function appears to be the solution but it isn't working....now i'm thinking "ok so i have a value and different things to print out so let's look for a switch, maybe it can understand that" switch function found under the form of choice, i get it sorted but am stuck wondering why the heck was the if and value combination not working.
Simple answer to that : value doesn't work well with function results, a known bug listed by someone in a comment, a comment i have failed to read for about 45 minutes of trying to understand.
All in all it worked well for the person asking for it so it's nice. -
See now why I understand that in essence given a vector (parameters), you modify weights and biases minimally and these get passed through a set of dropoff style layers like ReLU and that in the end each layer leading to an output will basically sum up to a value that goes through sigmoid and concurrently equals the value desired once trained..... i don't see how this could cover all bases when parts of the math used to calculate the output is trigonemetric and polynomial. I mean not complex math ! Real basic things in my case, but a polar from cartesian coordinate conversion, angle and leg size, etc all going into determining that a target equals a landing zone and if not how to move things to it.
Is there something I'm missing where you kind of model the math because at best sin and cos could be a power series.75 -
My answer to their survey -->
What, if anything, do you most _dislike_ about Firebase In-App Messaging?
Come on, have you sit a normal dev, completely new to this push notification thing and ask him to make run a simple app like the flutter firebase_messaging plugin example? For sure you did not oh dear brain dead moron that found his college degree in a Linux magazine 'Ruby special edition'.
Every-f**kin thing about that Firebase is loose end. I read all Medium articles, your utterly soporific documentation that never ends, I am actually running the flutter plugin example firebase_messaging. Nothing works or is referenced correctly: nothing. You really go blind eyes in life... you guys; right? Oh, there is a flimsy workaround in the 100th post under the Github issue number 10 thousand... lets close the crash report. If I did not change 50 meaningless lines in gradle-what-not files to make your brick-of-puke to work, I did not changed a single one.
I dream of you, looking at all those nonsense config files, with cross side eyes and some small but constant sweat, sweat that stinks piss btw, leaving your eyes because you see the end, the absolute total fuckup coming. The day where all that thick stinky shit will become beyond salvation; blurred by infinite uncontrolled and skewed complexity; your creation, your pathetic brain exposed for us all.
For sure I am not the first one to complain... your whole thing, from the first to last quark that constitute it, is irrelevant; a never ending pile of non sense. Someone with all the world contained sabotage determination would not have done lower. Thank you for making me loose hours down deep your shit show. So appreciated.
The setup is: servers, your crap-as-a-service and some mobile devices. For Christ sake, sending 100 bytes as a little [ beep beep + 'hello kitty' ] is not fucking rocket science. Yet you fuckin push it to be a grinding task ... for eternity!!!
You know what, you should invent and require another, new, useless key-value called 'Registration API Key Plugin ID Service' that we have to generate and sync on two machines, everyday, using something obscure shit like a 'Gradle terminal'. Maybe also you could deprecate another key, rename another one to make things worst and I propose to choose a new hash function that we have to compile ourselves. A good candidate would be a C buggy source code from some random Github hacker... who has injected some platform dependent SIMD code (he works on PowerPC and have not test on x64); you know, the guy you admire because he is so much more lowlife that you and has all the Pokemon on his desk. Well that guy just finished a really really rapid hash function... over GPU in a server less fashion... we have an API for it. Every new user will gain 3ms for every new key. WOW, Imagine the gain over millions of users!!! Push that in the official pipe fucktard!.. What are you waiting for? Wait, no, change the whole service name and infrastructure. Move everything to CLSG (cloud lambda service ... by Google); that is it, brilliant!
And Oh, yeah, to secure the whole void, bury the doc for the new hash under 3000 words, lost between v2, v1 and some other deprecated doc that also have 3000 and are still first result on Google. Finally I think about it, let go the doc, fuck it... a tutorial, for 'weak ass' right.
One last thing, rewrite all your tech in the latest new in house language, split everything in 'femto services' => ( one assembly operation by OS process ) and finally cramp all those in containers... Agile, for sure it has to be Agile. Users will really appreciate the improvements of your mandatory service. -
I feel a bit confused rigt now.
Did i misunderstand something with this random little excercise?
" Write a Java program to find the index of a value in a sorted array. If the value does not find return the index where it would be if it were inserted in order. Example:
[1, 2, 4, 5, 6] 5(target) -> 3(index)
[1, 2, 4, 5, 6] 0(target) -> 0(index)
[1, 2, 4, 5, 6] 7(target) -> 5(index) "

I'm an iOS developer and I cringe when I read job specs that require TDD or excessive unit testing. By excessive I mean demanding that unit tests need to written almost everywhere and using line coverage as a measure of success. I have many years of experience developing iOS apps in agencies and startups where I needed to be extremely time efficient while also keeping the code maintainable. And what I've learned is the importance of DRY, YAGNI and KISS over excessive unit testing. Sadly our industry has become obsessed with unit tests. I'm of the opinion that unit tests have their place, but integration and e2e tests have more value and should be prioritised, reserving unit tests for algorithmic code. Pushing for unit tests everywhere in my view is a ginormous waste of time that can't ever be repaid in quality, bug free code. Why? Because leads to making code testable through dependency injection and 'humble object' indirection layers, which increases the LoC and fragments code that would be easier to read over different classes. Add mocks, and together with the tests your LoC and complexity have tripled. 200% code size takes 200% the time to maintain. This time needs to be repaid - all this unit testing needs to save us 200% time in debugging or manual testing, which it doesn't unless you are an absolute rookie who writes the most terrible and buggy code imaginable, but if you're this terrible writing your production code, why should your tests be any better? It seems that especially big corporate shops love unit tests. Maybe they have enough money and resources to pay for all these hours wasted on unit tests. Maybe the developers can point their 10,000 unit tests when something goes wrong and say 'at least we tried'? Or maybe most developers don't know how to think and reason about their code before they type, and unit tests force them to do that?12

Hello Devrant. I really need a second opinion on this one. I work in this promising start-up and our current evaluation is about 10 mill $. I have a vesting opportunity in the company where I earn 2.5% of none dilutable shares in the company over three years. I also get salary of about 500$ a month just to survive. Though it is the plan that I get a decent salary once we have more funding secured.
I'm the CTO of the company where we are 10 employees in total and 5 are in the development team.
I've been programming for about one year now so I'm not that experienced and some of the guys I lead are much more experienced than me. Which is good because I grow my skills quickly, but it is a challenge sometimes.
I'm really in doubt if I have got a good deal in the company. I started working in February and back then the company was valued at around 1.5 mill $. I have always been loose about not demanding money right away and said to the CEO that we will figure that out about the money eventually and I trusted him blindly. When he gave the offer of 2.5% vesting I just accepted it right away, because I was a beginner in coding and I just wanted to learn. Also I was traveling around the world for a few months at the time and it was a great way to get a little money quickly.
I also study together with two colleges who are some of my best friends. We study business development at university and have round 1.5 year left. It's a lot of work
but we've managed to only study about 1 week in advance of the exams and still pass. So we all still working full time on the company.
I've never known how many shares the other guys had, but yesterday me and the other partners had a meeting about some contract and the CEO pointed out how many shares everybody had. I was stunned to hear that the my two other colleges that I study with have 10% each. And the reason for that is that they helped start the company from the beginning and I've only joined when it was around 6 months old. Still I find it difficult to that that it's fair that they should have 4 times as much as me. I would say the amount of value we provide to the company is about the same. One of the guys is only the son of the CEO, which should not change anything.
For me it's not all about the money but I don't want to be taken advantage of. I can't determine if I'm being overdramatic about this and whether it is a good deal or if it sucks and I should find another place to work. Also my studies at the University are pretty much intertwined with the company by now. All our school projects are something that creates value to the company and if I leave I would have to dramatically change the direction of my education.
I know that there is a lot of information here and that I'm not the best at writing, but what would you have done in my situation?6 -
I don't know how it's out there, but where I'm from, we don't get a lot of practical classes. The curriculum has tried to include practical alongside theory but its just not working. All we do is theory and more theory. Maybe include a major portion of marks for practicals rather than theory. And yes, please no coding in paper.
Another major thing we lack is teaching logical thinking. I have met final year under grads who find using a (!foo) to invert the value of foo mind blowing. They would rather use a full blown if-then statement to do the same. I think we need to incorporate chapters that motivates students into logical thinking to make better programmers.
Another essential part CS education around here lacks is in relevant examples and chances for internship. If you're studying something, I believe you would understand it much better if you see and experience it. Curriculum should include a real world project that you would use in a daily basis. Maybe break down and analyse a successful application and its component. -
Rant!!!
Recently, there has been this issue on StackOverflow not been friendly to beginners. I don't fully agree with that. SO is strict and rightly so because if not that, we will be flooded with repeated questions and low value answers. As a programmer, I believe when I go to SO, I want an answer quickly and fast because most at times, I'm programming and the problem I have is preventing me from moving forward. To be flooded by repeated and low quality questions and answers wouldn't help anyone. Also, on most beginner programming tutorials, were people are advised to check sites like SO when they have problems, most of them tell their listeners or readers to check if the question has been asked before, before going ahead to ask. Even SO assists you when typing your question with similar questions just to make sure you don't ask repeated questions. I rarely downvote but I understand those who do. Also, there is this talk about 'inclusivity' and some relating it to gender. It looks like people tend to slap gender and race on everything these days. To make this clear, I'm not a white male so that one wouldn't say the system favors me so I don't see the problem. The fact SO collects data about developers and it comes out that, most of the partakers are males doesn't mean SO is favoring males. SO doesn't show your gender when you ask a question. It doesn't even show your gender in your profile so what's the issue here? It will be better to get to the root of why there are few females in computer engineering and solve it there rather than blaming a site because of data collected. To know where this rant is coming from, just search StackOverflow on twitter and read the recent tweets.6 -
The rear ducking continues. We've built a reliable translator in the dumbest fucking way possible, it's just lovely. I simply reused the structure for feeding data to the VM assembler, an array of arrays, where there's one array of (ins [args]) per node in the parse tree.
It's nice because nodes can be solved out of order without affecting the actual sequence in which the instructions are output. And if one statement (node) equals multiple instructions, you just push multiple entries to the corresponding array, or push nothing if you need to output nothing. Easy as goblin pie.
This is enough to convert an input language to the assembly-like intermediate representation we use for the virtual machine. So then there's doing it backwards: walk the same array of arrays, and map those virtual instructions to a physical architechture. I guess I could do the encoding to native binary myself, it'd certainly be interesting to try, but I'm burnt-out already so I'll just use fasm for now.
Initial test: wrote a test program in my own stupid language, ran the translator, dump output to file, assemble that with fasm, run with r2 -d.
Crashes? No.
Runs fine? Yes and no.
For fuck's sake, I don't have syscalls. Mainly because the VM doesn't have an operating system, lmao. I was testing virtual programs by just freezing state, terminating, then dumping the fucking registers and stack to the console, we have no I/O to speak of. Not even a real 'exit', VM handles that by reading a return value every step like a mentally damaged son of a bitch.
So anyway, I manually paste the linux mambo, you know:
mov rax,60
mov rdi,0
syscall
And NOW our program can end execution without crashing.
Okay then, so does the test code work correctly?
** DRUM ROLL **
Yes.
Ladies and gentlemen, mother fucking PESO is now a compiled language, and going forward I will be expectantly receiving your marriage proposals for reviewing. Oh, but not so fast, we still need a frontend...
Well, we'll handle that in the next few days. I'm just glad to be *nearly* finished with this fucking compiler, I want nothing to do with anything else ever, but we know that's not going to happen, so Lord please end my pain.
No sponsor as this rant has been paid for by tax evasion. -
What do you think of Elixir + Phoenix to build API’s? Is it a better choice than a more established language like Python or something more new like Scala or Clojure?
At my company we're going through a watershed moment where we're starting to discuss and think about re-building our digital foundations and nothing is off limits. I'm leading the discussion about our architecture where everyone can have their say into what the future looks like for our applications. We're currently on a Drupal (CMS) + PHP7/Symfony (Backend Content Repository) + Symfony Twig templates (Frontend)
Even though I have been developing in PHP most of my career, I personally love Elixir and spend a lot of my time away from work learning it but many of my reasons feels subjective like pattern matching, it's actor concurrency model, immutable data and not having to deal with classes/objects, and I'm not entirely sure how that translates to business value, advocating successfully for a tech stack change requires solid reasoning and good answers to challenges like how do we find Elixir developers when existing devs leave, how easy is it to build a CI/CD pipeline for Elixir/Phoenix, etc.4 -
There are just those days where nothing seems to work. I am now 8 hours on an issue that was estimated for 3 hours and new issues pop up every time where its not even my fault. In one instance, I get the correct value back, the next time with exactly the same parameters I get a COMPLETELY different Value back which keeps crashing my code. Who coded this thing that it is so inconsistent. Starts to get REALLY annoying. ._.1
-
I'm in a big fat fucking stinking rut, as in progress on this project has absolutely stagnanted.
Gonna rubber face your duck now **UNZIPS** excepts I don't have zippers, as joggers are the one true way; fake Adidas til I fucking drop.
Brain damage aside, I understand both how I've layed out the data and what I'm supposed to do with it. We have a virtual machine, an array of instructions and arguments for a given process within it, and we need to walk this array and map values to registers.
We also need to spill values inside registers to stack, IF they are required at a further point within that block. This also isn't terribly complex. We simply look forward in the array and see if the value is an argument to any instruction that *needs* this value to be loaded (ie, within a register).
So this implies multiple iterations; we need to better understand how one particular value is used throughout an F before we can make a final decision on how many registers and stack space are actually needed for the whole block.
Here's where it gets tricky. If there's a call, we need to be certain that the symbol being invoked has already been fully processed. Besides the obvious fact that recursion fucks me up, there's another matter: say a private method gets invoked by another private method. We can take advantage of this, by which I mean, sacrilege incoming so put on this toga.
Looking at the output for C compilers, it would seem this is not done in practice, I would assume because it's a pain in the ass. But when you have the guarantee that F will only be called internally, as that's what "private" means, there's two ways it can go:
0. It's well below the 13-20 cycle threshold, so you inline the fucker. No suprises there.
1. It's a more involved affaire, and invoked in more than one place, so you don't inline it. Codesize matters.
Recursion and [1] are the big deal things holding me back. Not because it's too hard, like I said this is kindergarten level abstraction. I'm just slow and fanatical, which is how I prefer to spell "constant obsessive paranoid delusions". I can see the potential optimization I can pull here, so I'm stuck trying to figure it out.
Idea would be, handling the register allocation and stack spill for an internal-internal (or deep internal; what we like to call a "guts" method) in synchronization with the *calling* processes. This is, fundamentally, violating all conventions -- but so under the hood no one will notice.
Let me give you an example. If we were to pass some value to a function, expecting to mutate it and get a different value back, in a lot of cases it'd be stupid to make an implicit copy by using two registers, one for input and another for the output. Dude, it's one cycle. Multiply it by a million, say sixty times per second, for every time you __needlessly__ make a copy of a value that we've already stated is mutable.
Clearly unacceptable. This is, in the strictest sense, everywhere in every single codebase. Premature micro optimization is the root of all goodness, God is great and praiseworthy. So how do we go about it?
Answer is I know and I don't know. By which I mean to say, this very thing I've done by hand. Assembly is fun. Now the issue is teaching a calculator how to do it. Not so fun.
There is a dependency chain between processes, as I believe I've kind of alluded to. I'm trying to make decisions on the side of the caller depending on the details of the callee, which is why recursion is rawdogging my soul. This is the same situation, it's inverting the direction of one or more links in the dependency chain, which makes no fucking sense.
And yet it does.
Brain, explain yourself.
How do *you* handle this without crashing?
Brain?

Alright then, that was a useless attempt at fuckery. Let's have a nap then, maybe it'll come to me in the morning. That's what I've been saying to myself for almost a month now.
Perhaps it is a hardcoded fuk.1 -
So I ran into a perplexing "issue" today at work and I'm hoping some of you here have had experience with this. I got a story-time from my coworker about the early days of my company's product that I work on and heard about why I was running into so much code that appeared to be written hastily (cause it was). Turns out during the hardware bring-up phase, they were moving so fast they had to turn on all sorts of low level drivers and get them working in the system within a matter of days, just to keep up with the hardware team. Now keep in mind, these aren't "trivial" peripherals like a UART. Apparently the Ethernet driver had a grand total of a week to go from nothing to something communicating. Now, I'm a completely self-taught embedded systems focused software engineer and got to where I am simply cause I freaking love embedded systems. It's the best. BUT, the path I took involved focusing on quality over quantity, simply because I learned very quickly that if I did not take the time to think about what I was doing, I would screw myself over. My entire motto in life is something to the effect of "If I'm going to do it, I'm going to do it to the best of my abilities." As such, I tend to be one of the more forward thinking engineers on my team despite relative to my very small amount of professional experience (essentially I screwed myself over on my projects waaaay too often in the past years and learned from it). But what I learned today slightly terrifies me and took me aback. I know full well that there is going to come a point in my career where I do not have the time to produce quality code and really think about what I am designing....and yet it STILL has to work. I'm even in the aerospace field where safety is critical! I had not even considered that to be a possibility. Ideally I would like to prepare now so that I can be effective when that time does come...Have any of you been on the other side of this? What was it like? How can I grow now to be better prepared and provide value to my company when those situations come about? I know this is going to be extremely uncomfortable for me, but c'est la vie.
TLDR: I'm personally driven to produce quality code, but heard a horror story today about having to produce tons of safety-critical code in a short time without time for design. Ensue existential crisis. Help! Suggestions for growth?!
Edit: Just so I'm clear, the code base is good. We do extensive testing (for lots of reasons), but it just wasn't up to my "personal standards".2 -
The move by Amazon to increase prices of Prime seems to me to be a negative move.
Now I’m not saying the increase hurts me financially or anything but it forces people to make a decision where there wasn’t one before.
With a few seconds of though it is easy to see that what we are paying for is their Amazon Prime Video, because there is no change or update to the Prime delivery services.
So now you have to think...
“Is Prime Video worry this increase?”
I don’t know about you, but personally I see Prime Video as a “me-too” product that adds little or no value.
I’ll keep Prime because I order a lot of shit, but others without this frequency of purchase may decide to leave.
Seems like forcing people to make this decision may not be a good move for Amazon.9 -
Harari said of the idea of Data-ism:
---
In its extreme form, proponents of the Dataist worldview perceive the entire universe as a flow of data, see organisms as little more than biochemical algorithms and believe that humanity’s cosmic vocation is to create an all-encompassing data-processing system — and then merge into it.
We are already becoming tiny chips inside a giant system that nobody really understands. Every day I absorb countless data bits through emails, phone calls and articles; process the data; and transmit back new bits through more emails, phone calls and articles. I don’t really know where I fit into the great scheme of things, and how my bits of data connect with the bits produced by billions of other humans and computers. I don’t have time to find out, because I am too busy answering emails.
---
I was initially entertained by the punchline, but that was soon followed by the rather depressing realisation that my only value to greater society is essentially as a data processing unit7 -
Today I was fighting a bug in php that resulted in a steady increase of the upload time of a picture. I printed it out together with some other like the amount of accesses on the image.
They where separated with <br> tags which were not displayed for some reason (maybe you already gueesed it here).
I ask my teacher to help me out, because the entry in my database was correct, the value I received was correct, but not the displayed value...
We even modified the database structure in order to find the bug, but it turns out the error was how I displayed the values. TIL that strings are not concatenated with a '+', but with a '.', the hard way.
Next problem: why is the access count incremented? Also why 3 times?😅 -
Heres the initial upgraded number fingerprinter I talked about in the past and some results and an explanation below.
Note that these are wide black images on ibb, so they appear as a tall thin strip near the top of ibb as if they're part of the website. They practically blend in. Right click the blackstrip and hit 'view image' and then zoom in.

Not much to look at, but I was thinking I'd maybe mark the columns where gaps occur and do some statistical tests like finding the stds of the gaps, density, etc. The type test I wrote categorizes products into 11 different types, based on the value of a subset of variables taken from a vector of a couple hundred variables but I didn't want to include all that mess of code. And I was thinking of maybe running this fingerprinter on a per type basis, set to repeat, and looking for matching indexs (pixels) to see what products have in common per type.
Or maybe using them to train a classifier of some sort.
Each fingerprint of a product shares something like 16-20% of indexes with it's factors, so I'm thinking thats an avenue to explore.
What the fingerprinter does is better explained by the subfunction findAb.
The code contains a comment explaining this, but basically the function destructures a number into a series of division and subtractions, and makes a note of how many divisions in a 'run'.
Typically this is for numbers divisible by 2.
So a number like 35 might look like this, when done
p = 35
((((p-1)/2)-1)/2/2/2/2)-1
And we'd represent that as
ab(w, x, y, z)
Where w is the starting value 35 in this case,
x is the number to divide by at each step, y is the adjustment (how much to subtract by when we encounter a number not divisible by x), and z is a string or vector of our results
which looks something like
ab(35, 2, 1, [1, 4])
Why [1,4]
because we were only able to divide by 2 once, before having to subtract 1, and repeat the process. And then we had a run of 4 divisions.
And for the fingerprinter, we do this for each prime under our number p, the list returned becoming another row in our fingerprint. And then that gets converted into an image.
And again, what I find interesting is that
unknown factors of products appear to share many of these same indexes.
What I might do is for, each individual run of Ab, I might have some sort of indicator for when *another* factor is present in the current factor list for each index. So I might ask, at the given step, is the current result (derived from p), divisible by 2 *and* say, 3? If so, mark it.
And then when I run this through the fingerprinter itself, all those pixels might get marked by a different color, say, make them blue, or vary their intensity based on the number of factors present, I don't know. Whatever helps the untrained eye to pick up on leads, clues, and patterns.
If it doesn't make sense, take another look at the example:
((((p-1)/2)-1)/2/2/2/2)-1
This is semi-unique to each product. After the fact, you can remove the variable itself, and keep just the structure in question, replacing the first variable with some other number, and you get to see what pops out the otherside.
If it helps, you can think of the structure surrounding our variable p as the 'electron shell', the '-1's as bandgaps, and the runs of '2's as orbitals, with the variable at the center acting as the 'nucleus', with the factors of that nucleus acting as the protons and neutrons, or nougaty center lol.
Anyway I just wanted to share todays flavor of insanity on the off chance someone might enjoy reading it.1 -
I’m the only junior software engineer at a small startup where I do mostly web development, as well as other bits and pieces (automation, ci/cd, etc)
Our software team is extremely small so we do not have anyone dedicated to QA. I usually just ask a team members with related experience to review my merge requests. So if I have a merge request for our ci/cd, I ask the software engineer with the most ci/cd experience to review the MR.
Recently I realized that my MRs will usually sit for days, and sometimes weeks without the reviewers taking a look. And when they eventually do, they don’t even run the code. It seems like they just gloss over it and look for obvious syntax or logic errors.
It makes me feel as if my code and efforts do not have much value to our team.
It also pisses me off because whenever a issue happens in our codebase, me and my code is the first thing blamed even if my code is not the issue
Is this typical in other companies? Or is this something I should speak to my boss about?4 -
TypeScript types are fun. Problem is: the check is compile-time only.
I just wasted an hour not understanding that an integer passed from command line was actually getting transmitted as a string. The library, where that value landed as parameter, happily ignored the non-matching type and worked as if the value has not been set at all!
Dear library maintainer, please enforce your parameter types! Throw an error right into my face saying I shall not pass anything but an integer! Don't just continue to work to produce false output correctly. Thank you!
Dear TypeScript, I really want type checks on runtime.
Dear JavaScript: Why did you ever think loose types were a good idea? (And I say that as a PHP developer as well.)2 -
I first try to figure out why I really want to build this and (if the project is intended that way) why someone would use it.
Then I strip the idea down to its bare minimums so I know what I should build for it to be of any value.
And then I start building until I no longer think it's worth working on the project.
For instance:
I am kind of surprised to see that in a world where cloud and apis become more and more leading, there isn't really a commonly accepted and flexible api management platform.
There are some cloud based platforms out there that can be configured using some interface but why is it like that? Surely you aren't going to deploy multiple versions of your core with different platforms right?
That's where my latest project comes in. I want to create an on-prem api management platform which you configure to work with your api during development. Then you can deploy it to any infrastructure alongside your core api.
This way you:
- are not bound to a specific cloud
- don't have to worry about security and firewalls
- get user management and rate limiting for free
I will probably create a collab for this once the platform is mature enough.1 -
A friend of mine studies mathematics and he told me about a project he has to do and we worked on it together a bit: Numerically calculate the arctan.
He dug out a nice series by (the one and only) Euler and we started massaging the thing to get it into a bit of a nicer form (there were (n!)^2 and other shenanigans) and we eventually succeeded after some stupid simple errors and arrived at a quite simple recursive progression. After that he also found a formula to transform a given value into the region where our formula actually mimics the arctan and we proceeded to proof this formula. The programming was straight forward and now we only have to find the radius of convergence which I suspect is pi^2 (but no proof).
I had a lot of fun doing this, fiddling around with the formulas and then programming it to see it actually becoming real.3 -
#Suphle Rant 11: Laravel board launch
The launch took almost 2 weeks more than originally slated, because I sought to install it manually, just as an outsider would. Installation steps had been documented, automated tests for the installation tests were passing. When time came to actually execute the binary from the terminal, we went from one obstacle to the other. First, were the relatively minor Composer/Roadrunner issues, eventually resolved by the helpful RR maintainers who sat with me through a Discord server for about 2 hours until their command ran the way I needed it to.
Next was the Psalm scare: One of my value propositions was the guarantee of eliminating all type related bugs in Suphle apps. I intended to use Psalm for that. Wrote tests as usual. Turns out the library behaves differently under conditions differing from raw CLI usage. I resurrected threads I'd opened since December that were left unattended, and with some help from the maintainer, we eventually got it to do what I need it to do.
I was all the more frightened by the fact that Transphporm had caused me to renege on one of my earlier promises. I can only miss so many targets. After this, the docs had to be updated with all the changes effected to accurately integrate those two. Project installation and initialization commands were ran rigorously to ensure all progresses smoothly.
Tagged one final release and suddenly became impatient to launch on our local Laravel group chat where I've been a member for the last 4+ years, where we've had a rollercoaster of emotions. In that time, I've refined my launch speech to suit that audience -- obviously, countless times. Not just a tame "It's my pleasure to announce what I've been working on", but near 40 messages going into details about the inner workings, why it was built, how it compares. An expose that dove deeper than I would anywhere else.
I scheduled a time for them to tune in and got some encouraging anticipation. Ended up deflated after posting the whole thing. Only about 5 persons interacted. 1 (who I've chatted with outside the board) was quite enthusiastic. Feverishly checked the docs but commented it was overwhelming and he'd need more time. Already starred the repository.
For some context, there are give or take 250 members on that board. Not all are active but activity there easily reaches a crescendo when the topic discussed is about inanities like what 3rd party services to use for SMS, how to receive salaries from abroad, or job openings. I was optimistic when the acquaintance mentioned above published a payment library and met a riotuous welcome as one of their own. Maybe, they are simply not fond of me and the speech should have been passed off to someone else.
I checked Packagist installs -- not more 10. For 3 years, I'd been hyped up for that night; but for some reason, the audience I considered myself closest to flopped, woefully. Thankfully, this isn't the main launch. I'm still holding out hope for that. If it fails, I would have sunk an immeasurable amount of effort and time, that nobody will compensate me for. That is the one place I go to see those more advanced than me in PHP. I constantly learn there and find stimulating conversations there.
Now, I can no longer predict reception from other presentations. All I can do now is hope1 -
Ok, @jestdotty , today, i give up on china.
I've been messaging with a rep who is taking the time to keep editing a contract... Im pretty sure she was genuinely trying...
As typing this we finally got to a 'correct enough' contract... so I could click the damn pay button.
Over the past 7 hrs.. at 3 back and forth exchabges and modifications at each issue:
1. Used previous PI from the dude i gave up on... so had a qty at 12 when only 11 exist a colour wrong for a crate of items, and listed the dude i refused to sign a contract under listed as the rep.
2. Now the item subtotals were off... just a few pennies or so... assumed she left the usd prices but calculated with ¥... didn't want alibaba to reject in a day so i checked if it was noted anywhere... Oh boy was it... VERY clearly, all caps, bold in the body of the total row... that the total was, exactly, 11680 (spelled out ofc) RMB aka ¥ chinese yen. I told her this, she sends me a cropped shot of the $ numeric total field... so i sent her the giant all caps bolded line, the one thatd typically be considered final say in most international courts... no clue where that value came from, it had zero relation to any actual values... and i was as curious as when chatGPT creates totally new, unique, lyrics for satirical german songs... i really tried.
3. Wrong incoterms (trade terms... abbreviated to a few letters... had it that I'd be physically going to the tbd port to accept/clear customs... no)
4. Technically it was accurate (well a few strange subtotals since she used ¥ half the time... told her it was fine as long as it had the company name on the label (gave 3 full examples to use whichever)
I get the contract ...shipping...
"To: Sara"
Then the right address (seriously wtf)
5. I point this out and carefully explain in mostly just examples and "the us government doesn't like anything being sent to just a first name, there's no legal way to sign for acceptance"
6. She gets stressed enough to tell me she doesn't have time to keep editing (since this horrid pile of poor formatting was just thrown at her a day ago... i dont point out the ridiculous irony)
7. Imo, the highlight of my night/morning... in her stress she promises me it'll ship right... sooo many issues there...
Even if it was delivered/allowed a signature for "sara" for 7ish large boxes just off a sea freight from china to a residence in the middle of a corn field (which tbh would be hysterical)...the IRS would have a valid reason to audit me... theyve done it w/o valid reasons several times, since I was 18 doing international trade and a contractual employee of a large gambling company, quarterly reporting, and ofc declaring more than my taxes in donating melted glass and crane game prizes...yea, they hate me and always do all that work to find the same thing... i underdeclare charity by 10%.
The entire concept of getting USA mail, even when pristine and you know logistics agents in every major company and port or distribution center, to properly deliver anything... ROFLOL ... and im already on some 'open and check everything' list with customs for a hysterical misconception they made years ago... cant/shouldn't get into detail publicly... but it was caused because 2 packages from different cities in China were both going to my address/through customs at the same time... package 1, 75 of those cheap af ball-pit hollow plastic balls for a 2yr old's bday(very delayed) package 2. 75 rechargeable batteries (the kind in power banks) 9600mah.
8. Told her to change "sara" to company name... glad it's registered to this address still.
It took me under 5min to type this... had to get the WTF out.
Dear AliBaba, please give an option to allow buyers to create the supply side contract for review, not just req modification... please?2 -
So I made a couple slight modifications to the formula in the previous post and got some pretty cool results.
The original post is here:
https://devrant.com/rants/5632235/...
The default transformation from p, to the new product (call it p2) leads to *very* large products (even for products of the first 100 primes).
Take for example
a = 6229, b = 10477, p = a*b = 65261233
While the new product the formula generates, has a factor tree that contains our factor (a), the product is huge.
How huge?
6489397687944607231601420206388875594346703505936926682969449167115933666916914363806993605...
and
So huge I put the whole number in a pastebin here:
https://pastebin.com/1bC5kqGH
Now, that number DOES contain our example factor 6229. I demonstrated that in the prior post.
But first, it's huge, 2972 digits long, and second, many of its factors are huge too.
Right from the get go I had hunch, and did (p2 mod p) and the result was surprisingly small, much closer to the original product. Then just to see what happens I subtracted this result from the original product.
The modification looks like this:
(p-(((abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1)-p)%p))
The result is '49856916'
Thats within the ballpark of our original product.
And then I factored it.
1, 2, 3, 4, 6, 12, 23, 29, 46, 58, 69, 87, 92, 116, 138, 174, 276, 348, 667, 1334, 2001, 2668, 4002, 6229, 8004, 12458, 18687, 24916, 37374, 74748, 143267, 180641, 286534, 361282, 429801, 541923, 573068, 722564, 859602, 1083846, 1719204, 2167692, 4154743, 8309486, 12464229, 16618972, 24928458, 49856916
Well damn. It's not a-smooth or b-smooth (where 'smoothness' is defined as 'all factors are beneath some number n')
but this is far more approachable than just factoring the original product.
It still requires a value of i equal to
i = floor(a/2)
But the results are actually factorable now if this works for other products.
I rewrote the script and tested on a couple million products and added decimal support, and I'm happy to report it works.
Script is posted here if you want to test it yourself:
https://pastebin.com/RNu1iiQ8
What I'll do next is probably add some basic factorization of trivial primes
(say the first 100), and then figure out the average number of factors in each derived product.
I'm also still working on getting to values of i < a/2, but only having sporadic success.
It also means *very* large numbers (either a subset of them or universally) with *lots* of factors may be reducible to unique products with just two non-trivial factors, but thats a big question mark for now.
@scor if you want to take a look.5 -
Been debugging a sp in oracle from 2 days a fucking sp of 2000 lines to see why it was not not giving desirable result. Turns out a fucking variable had a null value which was always satisfying the greater than condition an fucking up the flow. The fucking sp is being used since ages and nobody fucking noticed i mean what the actual fuck. And also the fucking indentation of the code how the fuck are u supposed to know which if ends where i mean come on put some fucking comments to your fucking code if u are gonna make it like it is gonna be the ultimate fucking sp which is being used god only know how many places.

The bug: Some string values for an identifier property in the data objects are being sent from our frontend prefixed with a '0'. Sometimes. When it happens, it usually gets stripped away again by the time it's passed to our backend. But not always.
This 0 is never explicitly set anywhere. I even searched for a few variants of " = 0" in both the frontend and backend projects without receiving any results. You might already be suspecting where this is going.
So it turns out.
The data object which holds this value is being initialized in the aspnet (don't ask) backend and passed to the frontend, which then hydrates it. This value is always an integer number, albeit incidentally so which is why string is used as the actual type. When this object is initialized, it's hardcoded with an anonymous type where this property is set as int because I guess someone figured "it's always an int though". Being a typed language, primitive scalars can't be null objects which means the property's value becomes the concrete int 0.
Okay weird. I can think of better ways of doing this but let's just set it to string as I can't start overhauling things right now. Let's just go find where this value is somehow concatenated into the incoming parameter.
You see, this happens because at the point where the frontend sets this value, it may be an int or string depending on where it came from, and I guess someone figured that in order to cast it to string you just go prop += arg seeing as the prop is empty string and all. Because explicitly casting it or - as much as I get a rash whenever I see it - going prop = "" + arg would be too verbose and unoriginal.
Bonus round: How come the 0 only sometimes made it all the way to our backend? The thing is that this bug has been fixed before. The fix is that because this string is "always" an int, you can parse it to int before passing it to the backend in case it has leading zeroes. This path is only taken in certain views because someone forgot to copypaste their fix into all the places this is repeated.
Sometimes you find a bug and you are just somehow more grumpy after fixing it.1 -
Rubber ducking your ass in a way, I figure things out as I rant and have to explain my reasoning or lack thereof every other sentence.
So lettuce harvest some more: I did not finish the linker as I initially planned, because I found a dumber way to solve the problem. I'm storing programs as bytecode chunks broken up into segment trees, and this is how we get namespaces, as each segment and value is labeled -- you can very well think of it as a file structure.
Each file proper, that is, every path you pass to the compiler, has it's own segment tree that results from breaking down the code within. We call this a clan, because it's a family of data, structures and procedures. It's a bit stupid not to call it "class", but that would imply each file can have only one class, which is generally good style but still technically not the case, hence the deliberate use of another word.
Anyway, because every clan is already represented as a tree, we can easily have two or more coexist by just parenting them as-is to a common root, enabling the fetching of symbols from one clan to another. We then perform a cannonical walk of the unified tree, push instructions to an assembly queue, and flatten the segmented memory into a single pool onto which we write the assembler's output.
I didn't think this would work, but it does. So how?
The assembly queue uses a highly sophisticated crackhead abstraction of the CVYC clan, or said plainly, clairvoyant code of the "fucked if I thought this would be simple" family. Fundamentally, every element in the queue is -- recursively -- either a fixed value or a function pointer plus arguments. So every instruction takes the form (ins (arg[0],arg[N])) where the instruction and the arguments may themselves be either fixed or indirect fetches that must be solved but in the ~ F U T U R E ~
Thusly, the assembler must be made aware of the fact that it's wearing sunglasses indoors and high on cocaine, so that these pointers -- and the accompanying arguments -- can be solved. However, your hemorroids are great, and sitting may be painful for long, hard times to come, because to even try and do this kind of John Connor solving pinky promises that loop on themselves is slowly reducing my sanity.
But minor time travel paradoxes aside, this allows for all existing symbols to be fetched at the time of assembly no matter where exactly in memory they reside; even if the namespace is mutated, and so the symbol duplicated, we can still modify the original symbol at the time of duplication to re-route fetchers to it's new location. And so the madness begins.
Effectively, our code can see the future, and it is not pleased with your test results. But enough about you being a disappointment to an equally misconstructed institution -- we are vermin of science, now stand still while I smack you with this Bible.
But seriously now, what I'm trying to say is that linking is not required as a separate step as a result of all this unintelligible fuckery; all the information required to access a file is the segment tree itself, so linking is appending trees to a new root, and a tree written to disk is essentially a linkable object file.
Mission accomplished... ? Perhaps.
This very much closes the chapter on *virtual* programs, that is, anything running on the VM. We're still lacking translation to native code, and that's an entirely different topic. Luckily, the language is pretty fucking close to assembler, so the translation may actually not be all that complicated.
But that is a story for another day, kids.

hey guys i need advise.
I currently got a job that i love with a lot of freedom. but the payment is not good and i am concerned that the company won't be there in the next 5 to 10 years.
I am a 25 years old, self taught programmer and my current employer is the only one I ever worked for. Recently I browsed xing and found a company which searches an employee with exactly my skillset (they need someone for a specific ERP system in which I am damn good at). The company is half an our away - my current job 20 minutes away. Also I think because the person they are looking for is rare because you need technical knowledge of windows and doors and you need to know how to administrate this erp system plus knowing some programming stuff.
There is also a very big company 10 minutes (walking) from home where I could apply. I think at this company i would start lower but could maybe study and working for them with higher expectations in long term (just google Hettich in germany here in the village this is big)
The problem I currently have is the following. If the company I work for is closing in lets say ten years, then I am 35 without a degree. I have a girlfriend - want to marry her and getting a child.
I have holiday now and i will apply for both companies. I feel very uncomfortable doing this because the company I work for is the company of my granddad. I don't have the balls to tell him that even if i get a raise that does not solve the 35 years issue.
Well, first of all I will just apply. Lets see how much value I have.
But I thought that asking you all may give me some other input to take into account. What are your thoughts on this?
PS: just a formal "sorry for my english" and thanks for reading6 -
Title: Error Popup Occurs --> To be discussed
Description: When I open the app -> I see the app screen -> then I see some text -> sometimes there is a popup showing an error message
We of course don't want any errors at all so we should hinder these error messages
No, this isn't parody, arrows and all its how some people write our tickets, why do they write it this way!?!? Where is the value!!?!? Where is the comprehension!?!?!? God I get so sick of it sometimes.7 -
This is how to find the base needed for any integer value p, where p>=5, such that the logarithm always equals e in python.
log(p, e**(log(p, e**e))) # equals e
Doesn't do anything besides that but this is another identity isn't?24 -
Somehow mocking xhr requests (?) for Axios is really hard to make it work. I use React Cosmos as I'm re-doing the frontend of this already running in production and works great, but when my component communicates with the backend it breaks and I'm unable to test the full behavior.
Then, it occurred to me that trying to mock Axios may not be the best. So I came with this scheme where I would have a configuration variable with a default value and change that when I need to work with React Cosmos, which in turn changes the behavior of `/auth` to return a valid JWT in response to a GET, put an Axios interceptor in my outermost Cosmos decorator and BAM! suddenly was able to develop and test my React components closer to how they would work in production.
It surprises me how simple this endeavor was, and because everything runs orchestrated by docker compose things run smoother.
(this is not an excuse to not to learn how to deal with the mocking issues of Axios, after all I wont have a working backend every time I work in some frontend application)5 -
What's really the matter with meetings?
I mean, we've all been annoyed at some point by some management person scheduling meetings we think of as pointless but I've actually found myself enjoying going to one where people can discuss and share ideas (dev related, mostly).
Sure, it's not great when you are focused and you have to stop to talk to some assholes sometimes but other times it didn't bother me to think they value my input/opinion somehow.
Surely the reason for their existence is not to make you waste time, right? 🤔1 -
Okay. Here's the ONLY two scenarios where automated testing is justified:
- An outsourcing company who is given the task of bug elimination in legacy code with a really short timeframe. Then yes, writing tests is like waging war on bugs, securing more and more land inch after inch.
- A company located in an area where hiring ten junior developers is cheaper than hiring one principal developer. Then yes, the business advantage is very real.
That's it. That's the only two scenarios where automated testing is justified. Other such scenarios doesn't exist.
Why? Because any robust testing system (not just "adding some tests here and there") is a _declarative_ one. On top of already being declarative (opposed to the imperative environment where the actual code exists), if you go further and implement TDD, your tests suddenly begins to describe your domain area, turning into a declarative DSL.
Such transformations are inevitable. You can't catch bugs in the first place if your tests are ignorant of entities your code is working with.
That being said, any TDD-driven project consists of two things:
- Imperative code that implements business logic
- Declarative DSL made of automated tests that also describes the same business logic
Can't you see that this system is _wet_? The tests set alone in a TDD-driven project are enough to trivially derive the actual, complete code from it.
It's almost like it's easier to just write in a declarative language in the first place, in the same way tests are written in TDD project, and scrap the imperative part altogether.
In imperative languages, absence of errors can be mathematically guaranteed. In imperative languages, the best performance (e.g. the lowest algorithmic complexity) can also be mathematically guaranteed. There is a perfectly real point after which Haskell rips C apart in terms of performance, and that point happens earlier on than you think.
If you transitioned from a junior who doesn't get why tests are needed to a competent engineer who sees value in TDD, that's amazing. But like with any professional development, it's better to remember that it's always possible to go further. After the two milestones I described, the third exists — the complete shift into the declarative world.
For a human brain, it's natural to blindly and aggressively reject whatever information leads to the need of exiting the comfort zone. Hence the usual shitstorm that happens every time I say something about automated testing. I understand you, and more than that, I forgive you.
The only advice I would allow myself to give you is just for fun, on a weekend, open a tutorial to a language you never tried before, and spend 20 minutes messing around with it. Maybe you'll laugh at me, but that's the exact way I got from earning $200 to earning $3500 back when I was hired as a CTO for the first time.
Good luck!6 -
Looking at @striker28 's rant made me think of my time I did my MSc and I think it needs it's own separate rant so here it goes:
So I did an MSc at one of the big league unis in London. First clue was during week 1 where in one of the class a mature student asked whether there would be actual coding during the course. There was an audible gasp from everyone else! Once the lecturer said the unfortunatly they wouldn't be you could hear the sigh of relief from the students...
Next up was all the lectures being placed in the freakin' basement of the university in crap, smelly rooms with annoying ticking A/Cs whereas all the social siences, business and other subjects had lecture halls and classrooms above ground. The contempt for CS from the university's direction was palpable.
Then there was the relegation to the theory-only (i.e. abstract with pen/paper) "tutorial" to the hand of T/As with bugger-all teaching experience. In short most were terrible and should've found a way to abscond themselved from this obligation which was part of the terms of their phd grants unfortunatly.
Further into the course there was the "group project". Oh boy! Out of the 5 in the group my now mature student friend and I were the only one commiting to the repo. There was either no code and a lot of bullshit from the others or crap code that didn't even compile despite their assurances it was all good.. Someone clearly never actually coded and pressed "run" in their lives which is fucking surprising since they've managed to graduate with a BSc and get into a MSc somehow. None of the code "made" by the other 3 persons made it into the master branch for release.
The attitude was that of "We (hahahah) wrote loads of code. We'll get a great mark!". At that stage the core wasn't even complete and the software didn't work yet.
Some of the courses where teaching things already 10 years out of date and when lecturer where pressed on that the few mature students that happen to be there the answer was always "yes, we are planning to update it for next year". Complete bullshit. Didn't help that some of the code on the lecture slides was not even correct! I mean these guy are touted as "experts" in their field...
None of the teory during the entire year was linked to any coding. Everything was abstract with no ties to applied software engineering. I.e. nothing like the real world.
The worst is that none of the youger students realised they were being screwed over and getting very little value for their money. Perhaps one reason why these evaluation forms have such high scores given on them. If you haven't had a job and haven't lived outside academia yet there is nothing to compare it to. It tends to also fall into confirmation bias (hey it's a top UK university, it must be worth it afterall! Look how much they ask for).
By the end of the year I couldn't wait to get the hell out. One of the other mature student sumed it quite well: "I will never send my children here."
Keep in mind that the guy had just over a decade of software engineering experience in the industry and was doing this for fun.
In the end universities are not teaching institutions. The lecturers's primary job is research and their priorities match that. Lectures tend to be the most time efficient teaching format for the ones giving them but, on their own, are not for the consumer.
To those contemplating university for CS: Do the BSc. Get your algo/datastructure chops and learn the basic theory. It is interesting. Don't get discouraged by the subject just because it is taught badly.
Avoid the MSc unless you want to do a phd and go for an academic carrer. You are better off using that year and the money to learn more on your own and get into colaborative projects (open source) on top of some personal ones. Build up your portfolio. It will be cheaper and more interesting!2 -

Stream of thoughts coming through
#justAthought 1
If you feel you are mentally unique (Not in retarded or disable kind of way, but having a different view of thinking, a different perspective, not-a-sheep-in-a-herd kind of mentality) , then you PROBABLY ARE, its just those who are not that mentally unique will find your thoughts absurd until you are proving yourself to be a successful person.
Even though you feel something is wrong in a current situation, and you can put some valid points in your argument, there would always come a point where your personal failures or average-ness would overshadow your valid points (kind of personal experience than a thought :/ )
#justAThought2 (Disclaimer: i am no fraud guru or priest, just a 9-5 curious , sleepless student-cum-professional)
I sometimes feel that the only good, meaningful goal that i could think for my life would be : to earn enough money to set up a small experiment environment , where I would initially take, around 25-30 people for 1-2 years. It would be an environment with totally $0 value for materialistic things like money, jewels, property,etc . Everyone is living free of tensions of basic services like food, clothes, house, taxes, work to live etc. Together we all will be collectively doing just these things: Making ourselves healthy , and more kind, spiritual towards other humans, animals, plants and environment, and thinking of ways to eradicate the value of "value".
We have already reached a point where we are generating even more harmful Technology than useful tech, how about changing the way of thinking and taking a small pause? I know a lot of people would be reluctant to do any work in such environment, but i believe one day or another, every one of these people has to come back to their usual jobs , but this time, not for money but for humanity.
Do you think this kind of environment is possible for the whole world? Because today most, if not all thinks that money is the ultimate goal. can we change that, and would that change be good?
#justAthought 3 (Disclaimer : 1. Its my mom's thought/whatsapp status , i kind off liked it. she is super religious by the way ^_^! | 2. more relevant for india/multi religious countries 3. for Indians: kind of thought from movie "oh my god")
There should be a regional law during so called "acts of god"(floods, earthquakes, other natural disasters) under which the donations given to religious places(temples, churches, mosques,etc) would be used to provide relief to affected areas.3 -
Pretty niche tool, but Sencha Architect!
It is a wanna be GUI-Builder/IDE for ExtJS, but neither works properly.
This rant is not about ExtJS, just about Sencha Architect, which my coworkers and I were forced to use.
If you want to join the ride, here an excerpt of just some of the issues:
- installation: already the setup is more of a gamble than an actual setup, either it works on your machine or it doesn't, plain and simple
- GUI Builder: just drag and dropping components is actually nice, but the editing capabilities are frustrating, you can't edit the UI code by hand at all, just through pre defined properties. If there was the need to really mix things up it wasn't possible, I couldn't even rebuild shown examples of their ExtJS documentation. Furthermore the property editor was data type locked, which means if you want to enter a string which ExtJS already supports, but architect locks the value as a boolean, you can't edit it at all, while still using Architect
- code editing: well it is a colored texteditor, which is fine, and I could live with that, but Architect let's you just edit areas where it allows you to - want to change something else? Nope not allowed
- autocompletion: there is none at all, same goes for refactoring, multi highlighting, string replacement, and others
- code storing: well now some may think edit it somewhere else, well no, also not possible... Architect not just only saves simple js, there is also a Json formatted file for everything you have created, which is needed so the tool can actually load it for further editing. They possibly never heard of DRY. But the worst of this code storing was actually using git along with it - have a merge conflict? Merge both files! Every single time, it was so damn tedious
There are a few more, but these were the worst I can remember.
Luckily I don't have to use it anymore!
Maybe they have fixed or changed a lot of it, because the developers were aware of the issues and eager to resolve them, as far as I was told on a roadmap presentation. And some of the tools they had released in the end of my time using ExtJS were actually really good, like an IDE plugin for the framework, and I liked using it. -
Hey DevRant,
I know there is a range of devs here from novice to expert. So I wanted to get feedback on a platform I was building.
Essentially it's a web platform where Devs can authenticate with their Github profiles and all their repos (non-forked) and pulled to the website to quickly create a portfolio for the users. I currently have two templates users can switch between I plan on adding more if it begins to catch on.
Besides that users will be able to message and find each based on their skills to possibly connect with one another to work on projects together.
I have a lot of features I want to implement, but it wouldn't make sense to do those things now, I would have to wait for the user base to reach a certain milestone.
So I just wanted to share it and get everyone's feedback and possibly if you see value in it to share it with their own companions

Againg symfony shitty:
look - I want to validate csrf. I found docs how to do it.
https://symfony.com/doc/2.8/...
"if ($this->isCsrfTokenValid('token_id', $submittedToken)) {
// ... do something, like deleting an object
}"
But how the fuck should I know what is token_id from this stupid writing?
I have debugged their code to find it out. What a fucking waste of time !!! Free shit. Companies could probably pay small fee for the symfony if they could find people who do better job. Because by paying salaries for finding such shit costs them anyway.
And there was a htmls where the token was:
<form name="form" method="post" action="/admin/policy/47/push-im-xml">
<button class="btn btn-xs btn-info" type="submit">Push IM XML to GA</button>
<input type="hidden" id="form__token" name="form[_token]" value="LDVrl52CYtbT-kDudsjzrNAdJuIyFZhafsgk9QDnWGs"></form>
Guess what was token_id : form
:D whf. How the fuck could I know? I have tried various ways before debugging liek form_token, form[_token], _token
Who could fucking think its 'form' ?!!!! Wth. This is a joke.9 -
Suddenly, I find myself in a crossroad situation. I have been offered a position which would align perfectly with my career path aspirations (cloud solutions architect) with double the pay to my current salary. If only those were the only variables in this equation, taking the offer would be a no-brainer. Alas, it is never that simple (unless all you care about are pay and career path, of course)…
So, let’s break it down to pros and cons of jumping ship, shall we?
Pros:
- double pay compared to current salary
- aligns with my career aspiration
- part of a team of cloud solutions architects (mentorship opportunities)
- varying projects (position is at a consultancy firm)
- shares of the company come with the position ($$$ if it grows)
- possibility to influence strategic decisions
- no more 2h+ commutes
Cons:
- it’s a consultancy startup (emphasis on both consultancy and startup)
- 100% wfh
- would mean losing my current team where we are well and truly glued together and have such great vibes (and I value this, very very highly - this really is the main con)
- would mean losing my current work environment, where we have a gym and sauna at the office etc all kinds of stuff that support my athletic lifestyle
- would mean I don’t have as many opportunities to visit my parents anymore (since they live close to my current office but not close to me)
- at my current position I have super interesting projects both ongoing and in the horizon for a long time to come
- would mean eating my words (see previous point, and the fact I’ve said to my TM ”I can see myself staying as long as this job offers me opportunities to keep learning skills that are meaningful to me”), and I value my integrity
- would mean leaving my colleagues in quite a hairy spot, effectively betraying them in my mind (when our lead dev jumped ship a few years ago, he left us in quite a limbo and hands full of shit we didn’t know what to do about… I don’t wish that situation for anyone)
So, to sum it up, my reasons to stay are more those of moral integrity and convenience, well as the will to see the wheels I got rolling to the end, whereas my reasons to go are more personal finances and career oriented. A difficult decision. What to do?14 -
I dont get it. Please give me one good reason to use mongoose with a mongoDB.
Once upon a time it might have made sense to use a schema for the db. Today the native driver supports schemas and can check them on inserting. Nevermind one should validate the data before its hitting the db. I listened to an 1hr podcast last week where one of the maintainers tried to give reasons why its might be a good idea to use mogoose, and he failed miserably.
It introduces dependencies that are useless, it doesnt really abstract anything useful from the native driver, its TS support is shit and I dont like the API.
Every time I see someone use it he either fails or doesnt explain at all why to use it. Its so redundant it makes me angry. We have enough abstraction already. We really dont need more code that doesnt provide value. Please just use mongo the way the people of mongoDB intended it to be used.1 -

Thinking to start smoking 🚬
Never tried it once in 26 years not even a sip even refused temptations from school friends
Now by starting a job, i have no security, ironically. I feel like i stepped at the leap of a bottomless pit and tomorrow i jump into it and fall... and fall....and fall..... No end.
I have no idea how to use ansible and rexify.org and thats what I'll need to use. I have no idea how to do devops with Azure, and thats what ill do. I only build devops with terraform on Aws.
The unknown of 9-5 is frightening me more than starting a business. Paradoxically, i think it would come as a relief to get fired within the first week from failing to complete literally everything
On top of that my blonde gf disappeared yesterday for 3-4 hours. No texts no phone calls. Called for 2 times no answer. Called 3rd time and got a voice message the phone was shut down. 3-4 hours later she said she was with mom at shopping and didnt have internet
I also caught her texting some random guy on instagram. They both have vanish mode enabled (texts delete themselves as soon as you leave the conversation). Confronted her today. She wont tell me the truth. Likes his pics on ig. Keeps lying. On a question "why do you have vanish mode enabled with him?" her answer is "well i guess married men always use vanish mode"
Im tired
Too much shit unraveling. The opening of 2024 already doesnt look good
Why do good people die in accidents or diseases but i dont and i live? Shits unfair. Why doesnt nature/God fucking kill me? I beg to die. I hope to die. I pray for something to kill me. It would come as such a relief.
This life is meaningless and empty to me. typeof(life) yields a void. I dont value it. Its shit. Whether succeed or fail its meaningless. Nihilism was right
I am literally a walking dead. Physically moving but spiritually dead. Mentally lost. I am the captain of a ship in the middle of the ocean who no longer knows where the ship is going
Why cant i just get cancer or something. Can cigarettes help me get it? Cause I'll start consuming that shit right away to speedrun that process
End it17 -
Hang with me! This is *not* a math shitpost, I repeat, it is NOT a math shitpost, not entirely anyway.
It appears there is for products of two non-trivial factors, a real number n (well a rational number anyway) such that p/n = i (some number in the set of integers), whos factor chain is apparently no greater than floor(log(log(p))**2)-2, and whos largest factor is never greater than p^(1/4).
And that this number is at least derivable, laboriously with the following:
where p=a*b
https://pastebin.com/Z4thebha
And assuming you have the factors of p/z = jkl..
then instead of doing
p/(jkl..) = z
you can do
p-(jkl) to get the value of [result] whos index is a-1
Getting the actual factor tree of p/z is another matter, but its a start.
Edit: you have to provide your own product.

It's so frustrating to explain rxjs pitfalls to the manager.
To avoid the diamond problems and glitches caused by combineLatest and debounceTime(0), I decided to use single stream with nested reactivity.
Then the manager asked me to use withLatestFrom instead of combineLatest.
Sure withLatestFrom makes sense to the original author, when the original author is able to remember the reactive graph and put proper dependencies to combineLasted/withLatestFrom accordingly, but anyone else who touches the component later needs to retrace the reactive graph to avoid the glitch. Sometimes it's just impossible when many dependencies are derived from combineLatest+debounceTime(0). When no one is trained to code reactively, I don't expect people to know where to put a dependency. After many trials and errors, the only way to avoid the diamond problem is to use nested reactivity where child streams are created within root stream each time root stream emits.
The mentioned manager put all sorts of side effects in observable chains. The manager keeps saying the stream is too large when their subscription functions (sometimes nested) are way worse with litered mutations everywhere. Anything in observable can be traced by go to definition but tracing side effects usually requires global searches.
Recently, he put startWith to the end of a synced stream to fix a bug where button would collapse when there is no content (initial null emission). Rather than fixing the default height, he thinks using startWith(defaultLabel) is a good idea. Of course, he doesn't know that a synced stream should only emit 1 value on new subscription and that extra emitted value will cause rxjs glich down the pipe.
I hate corporate jobs -
My question is very easy and it is possible that this is a stupid question but I need your help. I have tried to develop a component with a function where I implemented a require function. In this last function, I included a state where a "select" option send the value (the path of the css file) to update this state. The value depend the choice of the user. So, it partially works because when I come back to an option that I picked a few seconds ago, the require function doesn't work anymore. I am not sure that was the best option. I am a beginner. Can someone explain me the reason why "require()" stops to work and which is the best way to resolve this functionality please ?

So, I have joined this new company where I used to work few years back. Something happened before I rejoined, so no one is working there now except me. It's web agency run by my boss and I am the only employee working on over 7 projects including front end, back end, mobile, devops, and some marketing also.
Now, I got offers from couple of other series a funded startups who are willing to pay me 30% more salary. I know I will have less responsibility and more work life balance. But I hate the politics in those companies.
My current company is making good revenue but my boss isn't giving me the salary I am expecting.
He said it will take few more months to give me the salary I demanded.
I also want to build my own company and provide services someday. That's why I thought it'll be better to stick with the company so that I cam learn other aspects of the business.
So. If the company is making say over 200k usd a year and its paying me around 23k usd per year, isn't this kinda low salary for my experience, skills and value I bring?
How should I go about asking a raise?
Also, I don't wanna move to another big tech company. I hate coding questions in the interview as its been years I have prepared for a proper tech interview.
Also, how secure do you think my job is? Is there any future working here? Will I ever be able to reach a salary comparable to big tech companies?
Is it a good place be in right now? (i jave over 5 years of experience)5 -
New to AWS, is my best option for having a integer value (maximum number of items to process) that I can override for a lambda step function
to read a value from an S3 bucket where I can overwrite the value if I want to change it. This seems silly and I feel silly as I expect my situation should be simple and not novel at all.
For some reason I expected I could use an environment variable, but didn't see an option to overwrite it in the web GUI https://docs.aws.amazon.com/lambda/...2 -
A powerful bitcoin is harmful to the USA. Because the bitcoin-based crypto-economy bypasses the US sanctions. So the more bitcoin is used for international trade more the USA loses its manipulative and coercive control over the world economy. So it is essential to lower the value of bitcoin to maintain the imperial status of USD. A DRAMA that claims to seize bitcoin wallets without having access to the victim (here the attacker is the victim) will decrease the trust and lower the value of bitcoin. Such propaganda may regain the imperial power of the USD over international trade. It can be an insider's work, where the attacker's private key is already known. It can be a made-up story.12

What's the minimal feature set that can make a language as ornamented as JS into a comfortable REPL?
Should I write a full parser or should I try to patch my way around with regex?
It will have to interface a lot with JS so it has to be able to manage JS datastructures in some fashion, which means that I can't just make a whole new command line with its own programs.
My current plan:
Some delimiter (probably a semicolon) will take the output of a command and inject it in the next in case you decide halfway through a line to do some more processing, It also awaits promises and does some other nice stuff to make controlling such pipelines easy. I have an elaborate system in mind to decide where a value must be injected to make the line valid so in most cases you don't even have to indicate it. JS has beautifully simple syntax rules so I have a lot of technical balance to burn before I start building technical debt.
I have some ideas for automatic parentheses and commas in function calls. I realize while using a command line you do not want to tap shift often. My main idea here is that two names or values in js are always joined by an operator so the first missing operator is a call and following missing operators are commas until the end of line. This has lots of nasty edge cases though, like that no argument expression can begin with a unary operator or a bracket of any shape. You can always prepend a comma but it's cognitive load.
Anyway, do you have any suggestion or warning besides "js bad" which I know but it's the most popular sandboxable language and has a massive existing set of libraries which I kinda need.3 -

I am a student and I started learning typescript as an advanced project at the recommendation of my teachers because I am a bit ahead of where my software development course is.
I started by testing the logic of types, and then I encountered type: unknown.
According to the TS handbook:
"If you have a variable with an unknown type, you can narrow it to something more specific by doing typeof checks, comparison checks, or more advanced type guards that will be discussed in a later chapter:"
So according to what this says, if you check a variable of type unknown, to equal a certain object type, typescript will allow you to assign that unknown value a I tested this out with a data type - objects and typescript freaks out.
Also, if create object with a property assigned to a function, it won't even show you that property when you console.log the object
ALSO, you can't post urls in this website, so this website is also pretty trash.12 -
Not so awful I suppose as long as it's produces quality output
Still only interested in davinci
Question
When chatgpt recognizes stateful requests "modify the part of the procedure Jojon where it updates storeitem to add a column verifiedbyhuman and set it's value to true" is chatgpt feeding everything at once to do davinci ?1 -
App Review – Zomato 2.0
Some apps are as essential as oxygen by example of https://apps.apple.com/us/app/... . Zomato, for sure, is one of them. If you love to eat outside and you’re not living in a cave, chances are that you’ve already gone through Zomato on the web or used one of their mobile apps. If not – Zomato is the place where you can locate eating joints, scan through their menus, check for home delivery numbers and a lot more than that. If you are diabetic you keep sweets in your pocket, similarly Zomato is something every food-loving person needs to keep in their mobile phones(I agree how PR-ish that sounds but it’s true).
Zomato had recently integrated social features on its website. That was followed by the much needed overhaul of their mobile apps. They’ve also updated their iOS app recently and I decided to give it a shot. Zomato 2.0 on the iPhone is super slick to say the least. The redesign brings a lot of character to the app. The Zomato app is now much more smoother, cleaner and powerful. The added social functionality adds more value to the app.
Design and Features
The 2.0 update completely changes the entire look and feel of the app. Everything from the app’s start screen to restaurant details has been changed. The default menu lets you explore and search eating places. Now there are icons for top 25 restaurants, reviews, favorites and more. The icons have been perfectly placed and it’s very easy to spot what you’re looking for.
Everything is just right. The app is highly responsive and there’s hardly any lag. If any, it will depend on your internet connectivity. Browsing menus is still a breeze and I personally love the way you can toggle between information, menu, photos and last but not the least, the reviews. Everything placed just perfectly to help you make that ultimate make or break decision – to eat or order from here or not?
Social
Everything is getting social. Even the next door Dolly-beauty-parlor apps are getting more social now. Zomato just integrated its social features on the web recently and they’re now a part of their mobile apps. On the iPhone app you need to login to access these social features. There’s a Top Foodies leaderboard that could prove to be a crucial game mechanic for the app. Browsing users’ profiles allows you to follow users. The profile pages tie up a user’s reviews and followers. This is all pretty neat and a part of a major plan at Zomato to take over the world.
With lists, network, user reviews etc. there’s a lot more to the app. I’m hearing that there’s still a lot more to come when it comes to social features on the Zomato iPhone app. I better start following up with people and posting reviews. This just kicked Foursquare where it hurts the most. And with that I’ve lost the little amount of motivation I had to check-in to places on Foursquare1 -
fuck this shit.
fuck the pile of arcane shit that is ARCore.
fuck the fucking pile of overcomplicated shit that is mapbox.
fuck the idiotic frankensteiny steaming pile of shit that is "arcore+mapbox lifesized maps unity project" or how is it called.
fuck this retarded scammy culture when a company is doing meetups with investors before even having a working prototype.
fuck this stupid fucking culture where there's no time for some actual, sensible, creative work, just grab these two repos from github and ducktape them together and we'll call that our demo which we will present to inverstors.
fuck every fucking molecule of this fucking world.
i just wanted to be creative. to CREATE stuff. CREATE, not pile up dumb half-baked nonprojects made by someone else on top of each other until the smell is too strong for anyone to see if it's actually reasonable or not.
i wanted to create stuff. make games. design and make them. actual interesting ones which have actual value (because fuck the retarded gaming industry who's imagination doesn't go beyond "u a dude who does pew pew to other dudes", but that's a different rant).
fuck this disgusting, retarded, idiotic, boring, lonely, cold, lobotomizedly stupid world where the only way to succeed is a shitty pile of shit scammy scum.
fuck me for not being able to learn how to be scammy scum, so I could be successful too. -
Persisterising derived values. Often a necessary evil for optimisation or privacy while conflicting with concerns such as auditing.
Password hashing is the common example of a case considered necessary to cover security concerns.
Also often a mistake to store derived values. Some times it can be annoying. Sometimes it can be data loss. Derived values often require careful maintenance otherwise the actual comments in your database for a page is 10 but the stored value for the page record is 9. This becomes very important when dealing with money where eventual consistency might not be enough.
Annoying is when given a and b then c = a + b only b and c are stored so you often have to run things backwards.
Given any processing pipeline such as A -> B -> C with A being original and C final then you technically only need C. This applies to anything.
However, not all steps stay or deflate. Sum of values is an example of deflate. Mapping values is an example of stay. Combining all possible value pairs is inflate, IE, N * N and tends to represent the true termination point for a pipeline as to what can be persisted.
I've quite often seen people exclude original. Some amount of lossy can be alright if it's genuine noise and one way if serving some purpose.
If A is O(N) and C reduces to O(1) then it can seem to make sense to store only C until someone also wants B -> D as well. Technically speaking A is all you ever need to persist to cater to all dependencies.
I've seen every kind of mess with processing chains. People persisting the inflations while still being lossy. Giant chains linear chains where instead items should rely on a common ancestor. Things being applied to only be unapplied. Yes ABCBDBEBCF etc then truncating A happens.
Extreme care needs to be taken with data and future proofing. Excess data you can remove. Missing code can be added. Data however once its gone its gone and your bug is forever.
This doesn't seem to enter the minds of many developers who don't reconcile their execution or processing graphs with entry points, exist points, edge direction, size, persistence, etc.2
