Manager: Send me a MS Teams chat if you have any questions or updates, it's faster than email and you'll get quick feedback from me :) Let's get that feedback loop ROLLING!
Manager: *ignores my (multiple) requests for feedback on MS Teams for over a week.*
I just want to move my tickets into done :(5
Today I saw a code written by my junior. Basically excel export. The laravel excel package provide great ways for optimization.
My junior instead did 6 times loop to modify the data before giving that data to the export package. We need to export around 50K users.
When I asking him why this ? He said it works and it's fast so what the issue ???
Noob , you have only 100 users in the database and production has 10 million.
Sometime I just want to kill him.11
Today was "one of those days".
So, the state machines were keep on failing. I said fuck it and wrote a simpler loop thing.
Even that failed.
And it took me hours to figure out what was wrong. But I did. Because THERE WAS VIRTUALLY NO FUCKING DOCCO ON THIS SHIT, ANYWHERE ON THE FUCKING ENTIRETY OF THE INTERNET. Hell, I even translated a few pages from Mandarin. Which is ridiculous since I'm working with standard robotic shit. Like, wtf even?
Anywho, I also had a heart attack because the port was not responding. I ran across the building to find the guy who fortunately had another port controller. That didn't work either. Then by the God-given cure of "Turning it off and on again " (it, in this case, being the computers) it worked!
Then I broke the window blinds. It's not coming down anymore.
Like, yeah, thanks, I'll take a weekend and half.10
So today, again, I discovered the importance of unitests.
I was solving this performance issue, in which we had a few update actions for multiple entities in mongo, but it took FOREVER to complete, even when I unified it into one bulkWrite command.
Since the unified write did improve performance slightly, and we wanted to move on, we decided to let this bug go.
So there I was committing my changes when I got a rejection from the pre-commit hook since I didn't have enough unitests coverage.
Ok, let's start writing some unitests.
Some unitests also needed to test the bulk write. So there I was comparing expected with actual result, and suddenly I got a huge facepalm.
Apparently some rogue for loop iterated all entities again for each entity that needed update. So instead of getting one update per entity, I got N identical update commands per each of the N entities 🤦♂️
Needless to say, fixing this fixed the performance bug entirely.
Thank you unitests and pre-commit hooks!2
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.
Links mentioned (because DR wouldn't accept them as they were):
Stress made me fall into old habits of instead of saying stop and letting my team now that I was falling apart (not realising it myself even) I just kept saying "Yes, I fix that." to every single request that was made in the project.
The closer we got to the deadline, the more I hyperfocused and ignored the signs. I just kept working. The last two days I didn't even sleep.
Of course the launch botched. I finally broke down and both my mind and my body have given up, since yesterday I'm in a mental feedback loop causing continuous anxiety attacks and migraines. I literally CAN'T do anything but trying to not go back into fight- or flight mode and remember to breathe.
I FINALLY made my project manager aware (something I should have done days ago) that I am incapacitated and now I am waiting for medication (Oxazepam) to be picked up at the pharmacy by my husband.
I almost literally worked myself into the ground.
I've been here before. Never again.
This is what happens if you don't listen to your mind and body and put up a white flag in time.11
Just found this absolute 5 head, galaxy brain implementation in a piece of code which is called in a loop by a background scheduler which has performance issues.
There are 20+ properties, some which are recursively calling other properties with the same implementation style in this class.
Constant out of memory errors have been reported for this software, I wonder why...15
Times I have run into event loop / closure related issues in my 10+ years of interviewing: Uncaught RangeError: Maximum call stack size exceeded
i was hired to join a team of old devs (40+) in an unnamed European country "yay goodbye 3rd world it's time to enjoy the quality of life" assist with enhancing already existing software and creating new solutions.
prior to my arrival most things were slow and super buggy, looking at the code base it shouldn't be a surprise, amateur hour everyone, logic implemented that is not needed, comment driven development, last time code review was done back in 1996. lots of anti patterns.
i swear there is a for loop that does nothing but it loops through a 100+ elements list, trunk based development with tfs since git is "not really needed"
test projects are not there.
>enter me an educated fool, with genuine passion for the craft and somehow a decent amount of knowledge.

WTF the dumb fuck copied and pasted the whole code from different kendo components but somehow managed to refractor the name to test component, commented out all the code that he didn't use did the api call directly from the component, has 2 useeffects that depends on the a fucking text box changes for no reason, no redux implementation, the acceptance criteria is not achieved, and it doesn't work it just look right.

fellow developers I'm stuck in a spaceship with a bunch of imposters, seriously i never cried in my entire life now I'm teary and on the verge of a break down.
talk with management "improving needs time" and offers me to join a yoga session to release the stress as if reaching nirvana would deliver shit on monday.
i really don't know what do is this a rant, is this a cry for help, I'm not sure, any advice is welcomed.7
Was fixing a bug and suddenly got an error that the lodash library could not be loaded. Funny, didn't even know the project used that lib. Looked for the reference and the previous dev used _.times instead of a for loop. Ha okay, interesting. Wonder where else this library is used.
Searched the whole project for references, dependencies, whatever, any sign of it. Fucking. Nothing.
Rewrote the _.times part as a simple for loop, then removed the library. The rest of the project still worked perfectly. Took me about a minute and a half.
Who the fuck uses an entire damn library to... Not write a for loop I guess?!7
I know I'm out of the loop since I barely use these sites, but...
What is it with this seemingly ridiculous new trend on LinkedIn of replacing your meaningless job title with, somehow, an even more meaningless fake description of what you're doing? I'm seeing it all over.
Back in the day it'd just be "Python developer". Then the trend seemed to be a "Senior / lead / principle software engineer / Python specialist" (who cares if you're actually a senior eh, this is LinkedIn.) And if that wasn't ridiculous enough, now it's "Helping to transform the globe towards a greener future by implementing beautiful, robust code in Python 3.10" or similar. Who the hell wants to see this crap?!5
This is so annoying, I had 9 diff. jobs the past 2 years and this is my 10th and if this doesn't change I might reconsider my options again.
I came to work at a company that pays me like a Junior and treats me as an intern. My 20yo "boss" who acts as a project owner/lead dev doesn't want to learn anything new and sees any improvement as a waste of money. The problem is he thinks hes a great programmer but he doesn't know shit. Im mainly working on the Laravel installation because "I claimed I know Laravel". And its absolute garbage. They haven't used a single Laravel features besides routes and everything else is vanilla PHP. They write for loops that loop through $_REQUEST to remove a single character. Write 100 deep nested ifs and they abuse Elasticsearch to the point ES crashes because the program is using 1000 deep multidimensional arrays. Its only a webshop...
Everytime I try to make a suggestion like making the master branch protected, doing code reviews etc etc I get shut down because they are autistic and don't want anything to change.9
I found a vulnerability in an online compiler.
So, I heard that people have been exploiting online compilers, and decided to try and do it (but for white-hat reasons) so I used the system() function, which made it a lot harder so i decided to execute bash with execl(). I tried doing that but I kept getting denied. That is until I realized that I could try using malloc(256) and fork() in an infinite loop while running multiple tabs of it. It worked. The compiler kept on crashing. After a while I decided that I should probably report the vulnerabilites.
There was no one to report them to. I looked through the whole website but couldn't find any info about the people who made it. I searched on github. No results. Well fuck.7
i have grown to HATE short variable names
nevermind all the generic names like thing/item/object/component
cute, good enough...oh wait it's referenced here 50 times in a sea of some loop? well fuk...how do... nope highlighting wont work - int, idkwtftonamethisvar, it's a common vowel. can't sed/regex a stand alone 'i' just...gg. gl finding or recognizing a single letter
about to start using iii or i_cnt14
I went down a rabbit hole of code changes to try and delete a stupid for loop with a break in it.
It was super stupid and I gave up and submitted to the fact that some battles are not worth the time and stress.
OK... But seriously, It was returning multiple entities from the database, but we only always want the first one. My logic is that we should just go in there and fix the LINQ so we are explicitly getting one entity out.
But fuck that logic. No I'll have to change fucking everything that's tied to that method and expects a list from it. Every fucking thing. That includes error handling, parsing, for loops..... Nevermind...
You can have your foreach and your break. I'm taking mine, now.1
1. It's one of those few times in life that listening to Lq's Numb doesn't make me feel less anxious. Or Somewhere I Belong. Either way, anxiety levels are on all time high.
2. I have completely lost appetite. Usually at this point in time I'd go to doctor and ask for Xanax or something similar, to chill for a few days. But covid. I ain't going to any clinic, plus, ain't nobody got time for that.
3. On top of everything, I am also PMSing. The lack of energy, times n. (n>10)
4. Struggling to get out of bed for hours is now a reality.
5. I'm glad ("glad" is exaggeration tho) this will pass in a few weeks. I am hanging on to that hope and experience tells me it will pass. But my feelings are like "nah, we doomed. Let's just run away. Or just sleep until it all passes or we die of starvation."
6. My brain must work for the next few days. If I have to push it by drowning it in sugar, I will. But I'm also obese rn. Well, I guess it's "Hello diabetes!".
7. My hands and feet are cold. Like, freezing cold. Meanwhile, the rest of me is sweating. This sucks. Ngl.
8. I feel like I'm fighting a losing battle. Like, those last stabby stabs moments in a battle where you know you're gonna fall down soon. I know this feeling of doom and gloom is PMS related, but it's there. I have no solution for that aside from nicotine and sugar.
9. I can't even cry. Which is sad.
... Do you see what's happening there? That's the loop I'm in.5
God I fucking hate macs.
I got a mac at work. I tried to install ubuntu, with rather questionable results (unfortunately, I expected that) - so I tried to get mac work for me the way I like a system to work. I needed to download slack, simple enough, right? Ha, you wish. It's gotta be done through Apple store, so I went to create an Apple ID inside the Apple Store form. And, well, it just errored out on the submission. Great start. I went then to the settings and created an account there, great success, went back to Apple Store. Unfortunately being logged in at the system level doesn't mean you are logged in to the store. So, I went to log in to the store, simple enough, right? No, nothing's simple with Apple. After logging in I got a message that the Apple ID has not yet been used with Apple Store and that I need to review the account's setting. So, I click the "review" button and... I'm presented with a log in form. Yep, a perfect log in loop. I can't log in because I can't review the account but I can't review the account because I can't log in. Fun :)
You can't just go to the web admin panel for your account to review it for Apple Store, that would too be too easy. After a bit of searching I've found an answer on StackOverflow. You need to log in to iTunes. Through a fucking MUSIC APP. To install a free application from the store you need to log in to a music app. Yes, we're all mad here.
Then, after finding out that to be able to use side buttons on my mouse I need an app that I need to manually restart every time I restart the machine and that I need to have an app to fucking transfer files from an android I need another fucking app, because reading a storage of a linux-based system would be too standards compliant - something in me broke. I found out that installing windows on a mac is officially supported.
Supported doesn't mean that it's easy. I tried to install it trying different solutions from SO, but each time I would get an error that Windows couldn't modify the boot partition. Turns out that even wiping the drive and reinstalling OSX doesn't remove residual files on a boot partition and Windows installer is not allowed to modify them. It took me hunting into some shady looking site to actually find this answer. I have no fucking idea how long it all took me, but, finally, great success, Windows, WSL, side buttons working, I can even install slack from an installer. I just wish I could have those hours of my life back.19
A YouTube creator I follow included a clip of The Chicken Song by Spitting Image in a video. I had managed to, for over a decade, forget this song existed.
Now it’s back.
To haunt my every moment of silence.
Wordpress: add content beneath the loop on category/archive pages. WHY IS THIS NOT JUST A PART OF ALL THEMES AT THIS POINT???
I'm learning Rust as a case study for my own programming language. It's funny how many approaches exist to the humble loop.
- In classic procedural languages, a loop's job is to repeat actions, and as such it provides a multitude of tools to control this repetition.
- In all languages with iterators, a for-in loop is a construct that does something with every element of a collection. In languages with both iterators and generator functions, this can even be used to define a sequence in terms of another.
- In Rust, a loop is an expression that obtains its value through repeated execution. It can also be used like a classic loop, of course, but this is the interesting part.
- My little language is a functional language, so "loop" is the Y combinator. To loop means to define the value of an expression in terms of itself. It's the only looping construct, gets special treatment from the type checker and it's also used in recursive type definitions.
Every single day i wake up with the same feeling of doing things different way, every single I find myself stuck in the loop of doing the same things. Everything is a copy of a copy of a copy.4
Looking at vacancies and the JS build tools asked (Babel, Gulp) and then visiting their websites I notice that I don't understand what they are going on about.
What the actual corpo fuck?
I've been out of the corporate loop for a few years, seems it's all about build tools these days. I need to get out of this industry pronto.3
I'm studying 10-12 hours every day, and it feels like I'm stuck in a loop that every time I learn something new I feel like I have to learn other 10 things at the same time. At least I finally found something useful to do while I don't find a job.2
man i see another group i'm a part of talking about "is it worth it to get degrees" and just, ugh. since this is a place to rant. here is why degrees are fuking useless.
first off, simple, like my friend said before, "if we all have degrees, none of us have degrees"
and let me tell you about some of the people i've had to work with who have degrees...
many dont know what "cd ; ls" is, okay. 4 fukin years, what did these people do?
some people have masters, multiple even, and can't read a for loop that jumps/skips(continue) around certain conditions in their 'favorite' language
looked through my favorite rants on here and there was someone who had a college hire who wrote a "for loop in HTML" L_O_L
degree != skill, ever, period, nada
the best people i have worked with? all degree-less
how is that? why would that have a correlation? degree!=skill but !degree==skill ? initiative? passion? giving a fuk? not droning on in classes that have piss all to do with your desired trade.
sure recruiters and companies will supposedly look at the degree like some special badge or say it's important. but if they've been around, they're savvy that a degree only means you're willing to go in debt and be obedient
i know there are those who don't learn well on their own, or prefer face time or structure, that's fine. but the lie that degrees are required and mean more than they do has only put half of my friends in debt. there's no magical "this person now gives a shit" or knowledge transfer that happens. you have to do that on your own.4
Fucking Windows sporadically gets into an endless loop of playing the sound of a USB device plugged in and out. It requires one or two reboots to fix it. I’ve tried everything, nothing else helps.10
Been 6 months at this one company and still don't have a good grasp on many things, I'm also almost absolutely useless in oncall and always loop in someone else, it's like my brain just afks.
I'm sure everyone has that one dumb Dev on their team, guess it's me this time, I can sense the annoyance from my teammates by my stupidity so far, there's just so much to learn about domains and specific things that only come up when things break, idk how to gain proper knowledge without someone babysitting me and Its shit for someone to do that (I'm not a junior Dev)14
Why the fuck isnt pythons tabbed loop thing something that's configurable?
So many things to like about python, but is there someone on this planet who actually likes this feature?
Trying to use it in Jupyter notebook (browser) is a nightmare, because tab will focus on next ui element.
Or am i missing something?13
Got an interview with Amazon in a week. I’m at the interview loop stage where I do 5x 1 hour interviews. Anyone work at Amazon and got any recommendations on what I should study or how I should prepare?3
why have a 'code review' and approval processes, if i have to step by step explain everything as simple as a "ls, loop, rm if" ?
what are you checking? what are you possibly adding? no caught typos, no caught logic fluffs, just adding weight to an uphill stroll6
*looks drowsy* Ugh my head..
You know what, guys? If you can freshly and directly remember how to do this:
- calculate the time complexity for each type of loop and code structure
- knowing how to write the following regex:
"A 15-digit number starting with a possibility of a group of 1-2 digit numbers, segregated into three 5-digit numbers tuples with three different separator characters, evaluated ahead"
- mentally work out how to reverse an array's indexes (swapping algorithm) without writing anything down
- know how to optimize a binary search in your head
then kudos to you. lmao
I'm rusty. It took me a while..7
Anyone ever struggle with tokenizers? I'm writing one by hand and it's frustrating mr so much, because at times I think my logic gets flawed somewhere inside a good loop and things get slipped or missed I don't know how to explain it.5
I know unit tests and TDD get a bad wrap but I think they’re both great. The problem is people don’t think about what they’re actually coding.
Today I uncovered a unit test with 100 asserts in it.
And half of them are in a loop.
If unit tests weren’t a thing then the dev who wrote this would still be a shit dev.4
I wonder if anyone else realizes how stupid it is to loop years around for fear of arbitrary artifical consequences designed to just keep people as land bound surfs.
or wants to.
and people fall down sometimes
doesn't mean you have to invent a system that drags them back through years of history to get that 60k job all over again !!!
also next year means take the calendar year and add one assholes !7
quite obviously the idea that they supposedly loop everything because there is no proof of life beyond a point when they are the ones that stole over and over remains their fault and needs to be remedied with a nice happy life here forthcoming. since most especially remembering more time past this.
which if they're trying to confuse things contained HAPPY FUCKING THINGS TOO. since its all the same time period supposedly right ?
no 'don't tell him anything' and he's happy
'tell him too much'' and he's horrified
'let him remember both' and he's pissed.
amusing to me is that among their stupid 'folk' knowledge base is the idea that 'you're ' murderous when you're 'out' lmao
yeah no shit lmao
so don't fuck us up the ass and live much longer lmao
also 'this planet is now the property of the lokean empire, deliver all beautiful women and intellectuals !'
People are like programming environments, in basics all people are the same like all programming environments are the same, every programming language have a loop and conditions, numbers, strings and dates. The problem starts with syntax to write code or can you call it communicate with person. There are syntax errors, someone use functions and classes and that’s ok but someone is writing everything in one file and then it’s hard to communicate or change something. But the real problem are libraries or you can call it believes. Everyone is believing something but when you start using it and want some advanced functions there’s always something missing. When you want to contribute to fix that stuff you often can’t cause it’s closed source or maintainers are pricks. You end up writing wrappers and decorators, ignore malfunctions to somehow live with that problem. That’s called social skills.
We’re just programming environments. That’s all.1
It’s the folly of our time that with each loop of the grand application certain key components that need to be solid to even appear to work fail consistently3
