Search - "function"

So this guy passed large objects as function arguments directly instead of referencing. What a jackass. So the program was slow as fuck AND taking up too much memory.
So yeah, I'm basically ranting about myself.2 -
Manager: This code you wrote violates the single responsibility principle!!
Dev: How so?
Manager: You have one function that you call in *MULTIPLE* places. That’s too much responsibility for one function! Functions should only have one responsibility!! Creeping the scope of a function beyond that is a TERRIBLE way to write code!
Dev: But why spin up multiple functions that all perform the same thing?
Manager: Well if a function has a bug in it and you use that function multiple places then that bug exists everywhere you use that function. If a function only has one responsibility then if it has a bug that bug will only exist in the single place it is called! You really should think first before asking questions like that.

I need to render point clouds in OpenGL for a project I'm working on. The problem is it just becomes too damn slow when the point cloud size increases. So I'm trying to use LOD methods and nested octrees to speed things up. Also, I need to render text too in my OpenGL scene. So now I'm stuck trying to show proper labels using Qt and OpenGL which is completely pissing me off by the way. And I'm not doing the actual speeding up thing I was working on earlier on and before that I was working on the actual function of my program. So I'm now deviated from the deviation.
Fuck my brain.5 -
I’m surrounded by idiots.
I’m continually reminded of that fact, but today I found something that really drives that point home.
Gather ‘round, everybody, it’s story time!
While working on a slow query ticket, I perused the code, finding several causes, and decided to run git blame on the files to see what dummy authored the mental diarrhea currently befouling my screen. As it turns out, the entire feature was written by mister legendary Apple golden boy “Finder’s Keeper” dev himself.
To give you the full scope of this mess, let me start at the frontend and work my way backward.
He wrote a javascript method that tracks whatever row was/is under the mouse in a table and dynamically removes/adds a “.row_selected” class on it. At least the js uses events (jQuery…) instead of a `setTimeout()` so it could be worse. But still, has he never heard of :hover? The function literally does nothing else, and the `selectedRow` var he stores the element reference in isn’t used elsewhere.
This function allows the user to better see the rows in the API Calls table, for which there is a also search feature — the very thing I’m tasked with fixing.
It’s worth noting that above the search feature are two inputs for a date range, with some helpful links like “last week” and “last month” … and “All”. It’s also worth noting that this table is for displaying search results of all the API requests and their responses for a given merchant… this table is enormous.
This search field for this table queries the backend on every character the user types. There’s no debouncing, no submit event, etc., so it triggers on every keystroke. The actual request runs through a layer of abstraction to parse out and log the user-entered date range, figure out where the request came from, and to map out some column names or add additional ones. It also does some hard to follow (and amazingly not injectable) orm condition building. It’s a mess of functional ugly.
The important columns in the table this query ultimately searches are not indexed, despite it only looking for “create_order” records — the largest of twenty-some types in the table. It also uses partial text matching (again: on. every. single. keystroke.) across two varchar(255)s that only ever hold <16 chars — and of which users only ever care about one at a time. After all of this, it filters the results based on some uncommented regexes, and worst of all: instead of fetching only one page’s worth of results like you’d expect, it fetches all of them at once and then discards what isn’t included by the paginator. So not only is this a guaranteed full table scan with partial text matching for every query (over millions to hundreds of millions of records), it’s that same full table scan for every single keystroke while the user types, and all but 25 records (user-selectable) get discarded — and then requeried when the user looks at the next page of results.
What the bloody fucking hell? I’d swear this idiot is an intern, but his code does (amazingly) actually work.
No wonder this search field nearly crashed one of the servers when someone actually tried using it.
Asdfajsdfk.rant fucking moron even when taking down the server hey bob pass me all the paperclips mysql murder terrible code slow query idiot can do no wrong but he’s the golden boy idiots repeatedly murdered mysql in the face21 -
Manager: You can’t define an async function without using await.
Dev: Yes you can.
Manager: Well you shouldn’t, there’s no point!
Dev: Yes there is. It can turn blocking synchronous logic into work performed concurrently. In this case the perform—
Manager: It’s called async *await*. Async *AWAIT*! Did you hear the two parts to that? You shouldn’t ever have one without the other. THEY GO TOGETHER. Worrying about concurrency is for people who use callbacks which just goes to show how out of date your skills are. I’m reading a book on javascript and there are so many advanced techniques out there that I haven’t even seen you use ONCE!
Dev: …
*I looked at the book he’s reading, it’s from the < ES6 era… no wonder he doesn’t see me using any of those archaic patterns/hacks/workarounds…*13 -
Fuck China.
Fuck the U.S. government.
Fuck the UK and Australia and all the other governments for taking advantage of the crisis of the last two years to get more power and money for their elites.
Fuck them all for starting COVID with their unsanctioned and unethical “gain of function” lab experiments and creating so much chaos that nobody really has a chance anymore at living the life they had dreamed of or so carefully planned for.
Fuck them for the out of control spending and money printing and inflation and even messing around with trying to regulate and tax crypto so we don’t have any kind of escape valve to live a normal, happy life.
Because of them, I can’t even enjoy my time off work. Even if I could plan a vacation that wouldn’t have to be canceled due to an outbreak or resultant supply chain issues, I can’t travel without severe restrictions that make it miserable and not worth the trouble.
Fuck them for making everyone into stupid monkeys fighting over opinions about data that is incomplete, misunderstood, misrepresented, or downright fixed toward a specific pharma-fascist authoritarian outcome.
And fuck them especially for being hypocrites and going to parties and generally not following their own rules they made for us when they think we’re not watching, and then persecuting and prosecuting us when we dare do the same.
Fuck ‘em all. I’m so done.21 -
I can't help but be disappointed in the direction that technology has directed us into, especially social media.
While I love my girlfriend, she more often than not spends her time scrolling away at the dumbest shit on Instagram, Facebook, .. reels. Reels everywhere. And she's not dumb, mind you. She's an engineer just as much as you (presumably) and I are. Just in a different field.
When looking into it online and stumbling upon more than one study, I learned about the term it had been coined.. technoference. That's the constant interruption of social media into our day-to-day lives, and the dopamine kick it gives -- more so than IRL peers do. Why that is, being the digital equivalent to McDonald's, that's beyond me. But somehow it seems to be better, all while the content isn't even useful. It doesn't allow you to learn anything, to gain insights, or to explore things that could serve you in the real world. Cat videos and random shit that's somehow.. funny? Having pretty much completely disconnected from social media years ago, I seriously fail to see how.
Maybe us nerds in the 90's and early 2000's telling everyone else how we'd change the world and prove everyone who called us freaks wrong, disenchanted as we were (and probably still are), were the catalyst for this social disaster. We had the cognitive skills to do it, but not the social equivalent. I feel guilty... Even though I've always been part of a big tech resistance in some capacity, I still feel guilty. Because I'm one of those people with the skills of those who created this trash fire of a societal status quo. Everyone glued to their screens, 95% of the time not for work. Not even to aid one's ability to function in the real world. Just to combat boredom. All day, for many hours on end.
Where is it going to end? When will people realize the dystopia we got ourselves into? Will anyone but a few fight it? Would those who don't fight it even care?17 -
I messaged a professor at MIT and surprisingly got a response back.
He told me that "generating primes deterministically is a solved problem" and he would be very surprised if what I wrote beat wheel factorization, but that he would be interested if it did.
It didnt when he messaged me.
It does now.
Tested on primes up to 26 digits.
Current time tends to be 1-100th to 2-100th of a second.
Seems to be steady.
First n=1million digits *always* returns false for composites, while for primes the rate is 56% true vs false, and now that I've made it faster, I'm fairly certain I can get it to 100% accuracy.
In fact what I'm thinking I'll do is generate a random semiprime using the suspected prime, map it over to some other factor tree using the variation on modular expotentiation several of us on devrant stumbled on, and then see if it still factors. If it does then we know the number in question is prime. And because we know the factor in question, the semiprime mapping function doesnt require any additional searching or iterations.
The false negative rate, I think goes to zero the larger the prime from what I can see. But it wont be an issue if I'm right about the accuracy being correctable.
I'd like to thank the professor for the challenge. He also shared a bunch of useful links.
That ones a rare bird.22 -
Interviewer: "Using this 2D array and calculate.."
Me: "This input isn't a 2D array though. Do you want me to parse or construct a 2D array then.."
"It is a 2D array."
"Uh.. ok..and if it's not what if we.."
"Look my notes say you must use this input, and treat it as a 2D Array"
"What if I wrote a function for a 2D array similar to this input, but actually a 2D array"
"You must use only the input provided"
Me: does rain dance code for 20 minutes.
Interviewer: "hmm, maybe it wasn't a 2D Array. I like your efforts but that's all the time we have today."
I promise I can code, sometimes. It does help to have correct questions to give correct answers.1 -
I discovered a function in our database that converts integers to ordinals by concatenating the number and a suffix:
- ends in 1: add “st”
- ends in 2: add “nd”
- ends in 3: add “rd”
- else: add “th”
Simple! Except I guess nobody considered the 11st, 12nd, and 13rd iteration of this function…9 -
i had this weird dream. i invented a programming language that was connected to the physical world. every time an object was instantiated during runtime, a 3D printer would print this object immediately in real time, into the void of a confined space without gravitation (like a physical stack, but not like a stack). if this object was passed objects as function parameters of its methods, these little objects were printed as well and temporarily moved into the orbit of this object, orbiting it like electrons or little moons.28

What an absolute fucking disaster of a day. Strap in, folks; it's time for a bumpy ride!
I got a whole hour of work done today. The first hour of my morning because I went to work a bit early. Then people started complaining about Jenkins jobs failing on that one Jenkins server our team has been wanting to decom for two years but management won't let us force people to move to new servers. It's a single server with over four thousand projects, some of which run massive data processing jobs that last DAYS. The server was originally set up by people who have since quit, of course, and left it behind for my team to adopt with zero documentation.
Anyway, the 500GB disk is 100% full. The memory (all 64GB of it) is fully consumed by stuck jobs. We can't track down large old files to delete because du chokes on the workspace folder with thousands of subfolders with no Ram to spare. We decide to basically take a hacksaw to it, deleting the workspace for every job not currently in progress. This of course fucked up some really poorly-designed pipelines that relied on workspaces persisting between jobs, so we had to deal with complaints about that as well.
So we get the Jenkins server up and running again just in time for AWS to have a major incident affecting EC2 instance provisioning in our primary region. People keep bugging me to fix it, I keep telling them that it's Amazon's problem to solve, they wait a few minutes and ask me to fix it again. Emails flying back and forth until that was done.
Lunch time already. But the fun isn't over yet!
I get back to my desk to find out that new hires or people who got new Mac laptops recently can't even install our toolchain, because management has started handing out M1 Macs without telling us and all our tools are compiled solely for x86_64. That took some troubleshooting to even figure out what the problem was because the only error people got from homebrew was that the formula was empty when it clearly wasn't.
After figuring out that problem (but not fully solving it yet), one team starts complaining to us about a Github problem because we manage the github org. Except it's not a github problem and I already knew this because they are a Problem Team that uses some technical authoring software with Git integration but they only have even the barest understanding of what Git actually does. Turns out it's a Git problem. An update for Git was pushed out recently that patches a big bad vulnerability and the way it was patched causes problems because they're using Git wrong (multiple users accessing the same local repo on a samba share). It's a huge vulnerability so my entire conversation with them went sort of like:
"Please don't."
"We have to."
"Fine, here's a workaround, this will allow arbitrary code execution by anyone with physical or virtual access to this computer that you have sitting in an unlocked office somewhere."
"How do I run a Git command I don't use Git."
So that dealt with, I start taking a look at our toolchain, trying to figure out if I can easily just cross-compile it to arm64 for the M1 macbooks or if it will be a more involved fix. And I find all kinds of horrendous shit left behind by the people who wrote the tools that, naturally, they left for us to adopt when they quit over a year ago. I'm talking entire functions in a tool used by hundreds of people that were put in as a joke, poorly documented functions I am still trying to puzzle out, and exactly zero comments in the code and abbreviated function names like "gars", "snh", and "jgajawwawstai".
While I'm looking into that, the person from our team who is responsible for incident communication finally gets the AWS EC2 provisioning issue reported to IT Operations, who sent out an alert to affected users that should have gone out hours earlier.
Meanwhile, according to the health dashboard in AWS, the issue had already been resolved three hours before the communication went out and the ticket remains open at this moment, as far as I know.5 -
Stop using anal as a variable or function name wherever I look I see anal_this and anal_that please stop. Use analyze, analyzer or whatever and not anal_insert ( ) or anal_check ()13

So, I was going to complain about JS being finicky and not making a damned bit of sense, but it turns out that it wasn't JS's fault. Not entirely, anyway. It was the halfassed JS minifier middleware (written by the legendary dev himself) that was breaking the JS while writing it to the page.
The original problem:
My code worked. I removed some comments. Big ol' block of //'s. And suddenly $() isn't a function. But if I call $(); at the top, it all works!
It turns out the "minifier" caused JS to think my code was chaining off the previous JS line in the rendering pipeline instead of being a separate statement. so all it really needed was a `;` at the start. What threw me, though, was the last line of the previous blob of (non-minified) JS was a comment, so it should be a separate statement, right?
But as it turns out...
```
console
// JS really is finicky.
.log('Sigh.');

I've seen several rants about dumb/useless teachers, college and the CS degree studies; today is a good day to vent out some "old" memories.
Around two semesters ago I enrolled in a Database seminar with this guy, a tall geek from the 80's with a squeaky voice, so squeaky mice could had an aneurysm if they listened to him.
Either way this guy was a mess, he said he was an awesome coder, that we were still "peasants" when it came to coding, that relational databases had nothing on him since he was an awesome freelancer and did databases every day, that we had to redo the programming course with him and with his shitty, pulled out of the ass own C++ style guide with over 64 different redacted rules.
He gave us sample code of "how it should be done" in Java...it ain't my favorite language but fuck me a fucking donkey could have written better code with his ass!! He even rewrote Java's standard input function and made it highly inefficient. He still wrote in a structural paradigm in OOP languages! And he dared to make this code reviews were he would proyect someone's code and mock it in front of the class as he took off points, sometimes going to the negative realm (3,2,1,0,-1...)
But you know what's shittier? That he actually didn't even attend, 90% of the time, it was literally this:
> Good morning class
> Checks attendance. . .
> I'll be back, I'm going to check in...
> 1 hour 45 minutes later (class was 2 hrs long) - comes back
> do you have any doubts?
> O.o no...? I'm ok.
> We're done
Not only that, he scheduled from 4 to 17 homeworks throughout the week, I did the math, that was around 354 files from everyone; of course he didn't check them, other students from higher semesters did and they gained each point taken from students making students from lower semesters get the short end of the stick.
How did I pass? He didn't understood my code or database schema and he knew he couldn't fail me as he had no ground to stand on.
Thanks for listening, if you got to the end of this long ass post and had a similar experience I'd love to read it.13 -
God, I love when people name stuff right. Now I'm reading through an open source project, trying to find out how they solved a critical issue I'm facing now. It's not a small one but navigating through it is a breeze. Look through variable/function names and I don't even really need to read the code. Meanwhile, last assignment, there was "yangDataHandler" and "yangDataManager" that, obviously, had nothing to do with each other in either interoperability or functionality - and then half of the variables would get aliased to abbreviations. Uh, yes, sure it's obvious what
𝚋𝚣𝚋𝚠𝚒 variable means. Just let me run it through 𝚒𝚍𝚣𝚍() function.10 -

At my first big boy job at a start up with only 50 users, we noticed we had cloud cost spikes about 20x larger than we were expecting. I remember spending all night debugging it, checking the requests as they go through.
The culprit? Someone left an async on a UseEffect with a variable that was regularly updated as a parameter.
In other words: every time a request was fired, the variable would change… so the function would sense the variable changed and fire it again, and so on.
Felt like a total hero. -
In the Ruhr area (Germany) we have some very old, very strange words with strange meanings. One of those words is ‚Prutscher‘.
A Prutscher refers to a person who does things but never gets a good result, due to lack of knowledge or simple carelessness. Most of the time, Prutschers are people who are interested in certain subjects and often work in the related jobs, but who lack the motivation to properly train themselves, learn what there is to learn and to always keep up with their technologies .
Here are a few examples I've stumbled upon so far in my career:
- Developers in their 60's who read a book about PHP 25 years ago and decided to become a software developer. Since then haven't read anything about it. Who then now build huge spaghetti monoliths for large companies, in which they prefix every function, every variable and constant with their initials and, of course, use Hungarian notation.
- People who read half a fucking tutorial about <insert any fancy js framework here> and start blogging/tweeting about it
- Senior web developers who need to be told what the fuck CORS is and who can't even recognize CORS related errors in their browser console.
- People who have done nothing else for 18 years than building websites for companies on Wordpress 1.x and writing few lines of PHP and Javascript from time to time. Those who are now applying as a frontend dev due to the difficult economic situation and are surprised that they are not accepted due to a lack of experience.
- Developers who are the only ones working on Windows in the team and ask their Linux colleagues for help when Windows starts bitchin.
- People who have been coding for 30 years, have worked with ~42 languages and don't know the difference between compiled and interpreted languages in the job interview.
- Chief developers at a large newsletter-publisher who think it's a good idea to build your own CMS (due to a lack of good existing ones, of course).
- Developers who have been writing PHP applications for multinational corporations for 25 years and cannot explain how PHP is executed. They don't even know what the fucking OPcache is, let alone fpm. FML
- People who call themselves professional developers but never ever heard of DRY, KISS, boy-scout rule, 12-Factor App, SOLID, Clean Code, Design Patterns, ...
- Senior developers wondering why the bash script won't run on their fucking Windows machine.
- Developers who consider Typescript to be a hindrance and see no value in it.
- Developers using ftp for deployments in 2022
- Senior Javascript Developer applying for a job and for whom Integer is a primitive data type in JS.
- Developers who prefer to code without frameworks and libraries because they are only an unnecessary burden/overhead and you can quickly code everything up yourself.
- Developers who think configuring their server(s) manually is a good idea.
You fucking Prutscher. What you have already cost me in terms of work and nerves. I can't even put it into words how deeply I despise you. I have more respect for the chewing gum that has been stuck in my damn trash can for the past 3 years than I do for you guys. You are the disgrace of our profession. I will haunt you in your dreams and prefix every fucking synapse of your brain with MY initials.
As a well-known german band once sang in a very fitting song: I wouldn't even piss on you if you were on fire.
If you recognized yourself in one of the examples here: FUCK YOU!38 -

... so... maybe not that much of a thing, but i think it is:
a gal (27 years old) i started teaching programming two weeks ago, who had literally no previous experience with programming, algoritmization nor c#...
... just now, after 3 lessons of 6 hours altogether, and after yesterday when i explained to her what arrays are and reminded her what loops do...
... invented bubble sort. on her own. no googling. on paper. no "trial and error code typing and running".
i'm actually pretty proud of her :)
... putting the algo concept into actual code will still be a bit of a struggle, but yeah, hell, can't help thinking that she's actually pretty smart :)
(p. s. fist lesson was i drew uml of a fibonacci algo and forced her to understand what it does, second lesson was i explained the minimum required c# syntax for her to be able to implement it and forced her to write it (with as little help as i could), third lesson was the concept of array and "okay, now here's array of numbers, make a function that will sort them")
looking forward to what will happen when i explain recursion and nudge her towards quicksort O:-)8 -
Years ago I used to work a guvmant site. They had really strict security rules for internet and how you spent your time. Makes sense considering what that site did. I was a support engineer for some of their process control equipment.
I was approached by an operator supervisor to install dvd player software on a business machine (non process related). Basically just a general purpose PC with no function other than time cards and general office use. I was fine with the request, but the reason was for watching movies during a holiday period by the operators. Not for anything official. So I made some noise about my dislike of this request feigning moral superiority. But the supervisor swore up and down it was for "training" dvds.
So I wrote a simple windows script. The script basically popped up a window that said:
"Security has detected unauthorized media inserted into this machine. Please state the reason for this infraction." It provided a dialog to enter a justification. After you entered the justification it said: "Security has been contacted and your user logged. You will be contacted shortly."
This script was then attached to the supervisors Start folder so it ran when he, and only he logged in. We made sure the "training" video (some movie) was already inserted at this point.
He logged in. He just about shit his pants when reading this. He promptly logged and left the building to walk somewhere else in the site. We called him and let him know it was a gag. His response: That son of a bitch Demolishun!2 -

Consumers ruined software development and we the developers have little to no chance of changing it.
Recently I read a great blog post by someone called Nikita, the blog post talks mostly about the lack of efficiency and waste of resources modern software has and even tho I agree with the sentiment I don't agree with some things.
First of all the way the author compares software engineering to mechanical, civil and aeroespacial engineering is flawed, why? Because they all directly impact the average consumer more than laggy chrome.
Do you know why car engines have reached such high efficiency numbers? Gas prices keep increasing, why is building a skyscraper better, cheaper and safer than before? Consumers want cheaper and safer buildings, why are airplanes so carefully engineered? Consumers want safer and cheaper flights.
Wanna know what the average software consumer wants? Shiny "beautiful" software that is either dirt ship or free and does what it needs to. The difference between our end product is that average consumers DON'T see the end product, they just experience the light, intuitive experience we are demanded to provide! It's not for nothing that the stereotype of "wizard" still exists, for the average folk magic and electricity makes their devices function and we are to blame, we did our jobs TOO well!
Don't get me wrong, I am about to become a software engineer and efficient, elegant, quality code is the second best eye candy next to a 21yo LA model. BUT dirt cheap software doesn't mean quality software, software developed in a hurry is not quality software and that's what douchebag bosses and consumers demand! They want it cheap, they want it shiny and they wanted it yesterday!
Just look at where the actual effort is going, devs focus on delivering half baked solutions on time just to "harden" the software later and I don't blame them, complete, quality, efficient solutions take time and effort and that costs money, money companies and users don't want to invest most of the time. Who gets to worry about efficiency and ms speed gains? Big ass companies where every second counts because it directly affects their bottom line.
People don't give a shit and it sucks but they forfeit the right to complain the moment they start screaming about the buttons not glaring when hovered upon rather than the 60sec bootup, actual efforts to make quality software are made on people's own time or time critical projects.
You put up a nice example with the python tweet snippet, you have a python script that runs everyday and takes 1.6 seconds, what if I told you I'll pay you 50 cents for you to translate it to Rust and it takes you 6 hours or better what if you do it for free?
The answer to that sort of questions is given every day when "enganeers" across the lake claim to make you an Uber app for 100 bucks in 5 days, people just don't care, we do and that's why developers often end up with the fancy stuff and creating startups from the ground up, they put in the effort and they are compensated for it.
I agree things will get better, things are getting better and we are working to make programs and systems more efficient (specially in the Open Source community or high end Tech companies) but unless consumers and university teachers change their mindset not much can be done about the regular folk.
For now my mother doesn't care if her Android phone takes too much time to turn on as long as it runs Candy Crush just fine. On my part I'll keep programming the best I can, optimizing the best I can for my own projects and others because that's just how I roll, but if I'm hungry I won't hesitate to give you the performance you pay for.

Is it just the novice in me that finds the Haskell community's misguided obsession over character count really annoying? Learn You a Haskell For Greater Good states
> Shorter code means less bugs
A lot of people and resources seem to share this opinion, but it's obviously false. Simpler code means less bugs, but look at this function which just means "apply this applicative to each element of a list"
> sequence :: (Applicative f) => [f a] -> f [a]
> sequence = foldr (liftA2 (:)) (pure [])
This isn't "less buggy", it's fucking madness. The same in JS, the king of unreadable languages, would be:
function sequence(seq, val, apply = (f, x) => f(x)) {
seq.map(f => apply(f, val))
}
Seriously, how can you design a strictly typed language that gets beaten by JS in readability?16 -

The company I work for offered a Javascript Course/Training for every developer to enroll, which happens to take place on 3 days. In the description it was ensured to be for everyone, doesn't matter if you are an expert or beginner: there's something to learn for everyone.
The company described him as a top coacher in Austria and that he is overbooked for 2 years. High in demand indeed. "Has to be good", I thought. As a relatively average JS developer, there has to be something to learn for me.
Sitting here the second day, I fucking regret to join this shit. I have never seen such a bullshit in my lifetime. Why the fuck would you even book this man, he doesn't even understand basic concepts of software engineering. Just reading down the script, opening the script on one laptop and showcaseing it on the other. When someone asks a question, there's a 70% chance he doesn't know the answer. It takes this scumbag 30 fucking seconds to define a function; probably making spelling mistakes alongside.
I don't even want to know how much this dude will make from this "coaching". Hoped that it'd get better over time but I don't see an improvement. Contacting my boss that I'll leave this "training".7 -
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 -
> turning the whole codebase into a muddy ball of dirt because the leader didn't like 1 (one) call to an async function on startup
Way to go buddy, you sure show them how it's done. -
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.

This whole corporate numbers game is killing me. I know I'm getting paid to do what I'm asked, I know. But the metrics are so one dimensional
You fixed the data of 20 tests? Doesn't count because you didn't code
You implemented a function to reduce recurrent failures in the future? Doesn't count because those already pass with time consuming workarounds
You spent half a day communicating and coordinating across teams to fix an issue? That's 1 test, this other person changed 1 line in 5 files, you're 4 tests behind4 -
Have a function that takes parameters and then performs a switch statement to determine what function to call next with those same parameters. One of those parameters is a Union type.
During CR, my reviewer said they’d like if instead of returning the function per case, I instead assigned a handler to the value of the function per case and then returned that handler at the end of the switch. Simple change, right? Only snafu, I’m casting one of the parameters on a per-case basis.
Somehow, through no fucking change of my own, TypeScript in its wisdom has decided that the type of that value by the time I call the next function is a fucking Intersection.
WHY THE FUCK DO YOU THINK IT’S AN INTERSECTION?! I’m fucking casting it per case! I’m ensuring it’s the right type for the next function called on a per case basis!
…. And that, my friends, is how I wasted a day with a stupid refactor that was ultimately just scrapped because no one could figure out how to make it work.
Goddamn fucking TypeScript. I3 -
My boss has zero emotions and empathy. How ironic for someone into product management!
He is 100% logical, maybe more. He is smart that way and yes, that is a skill to learn from him. He has good product management hard skills.
But, he is an emotional void. Zero humane feelings. He treats everyone like a machine. He is overly obsessed with documentation and wants every single word to be his way.
My writing and communication skills are his pet peeve.
Last Monday, our CTO was in office and he wanted to meet me. I was working remotely, so leads notified me. Even though our CTO runs a monkey business, I was eager and excited to meet him.
This week, my boss will be in office. He texted me to catch-up on coming Monday. I am anxious and worried even though my boss has great skills in our work function.
Furthermore, I find my boss overly critical about everything I do. Maybe it's not me and he does it with everyone, because I haven't been part of a group connect, so no idea. But dude.. give me a break.. give me some room to breathe..
What I heard from another junior, who joined us last month, is that one of the folks who resigned in past was because of my boss.
Feel like that I will move on from my dream organisation as soon as I complete little more than one year.
And apart from that, I scratched my eye glasses, Reddit permanently banned my account for no fault of mine, wanted to catch-up with a cousin, who is going through a rough phase, to cheer up the lad, but he won't answer our calls.
What a shitty weekend.
And yes, my boss is a hipster in the way he dresses and thinks.
He literally keeps saying that we need to use dark patterns like click baits, incite FoMo in our app users, add feedback loops, etc.3 -
I'm usually nice to people and try to look for the best in them... but this one time one of my colleagues gave me a code to review that, something about trees, can't remember, and the function was hammering the databases with 3 nested cycles, that's when I could no longer just watch. I was kinda mean on him that day, but as a result he did fix the problem and was really happy and I sensed a bit proud of himself as well.
Long story short, I believe he's not a software dev anymore. Kinda shame, I liked the guy, but he seemed enthusiastic of his new job and that is all that really matters in the end1 -
I don't know if I'm being pranked or not, but I work with my boss and he has the strangest way of doing things.
- Only use PHP
- Keep error_reporting off (for development), Site cannot function if they are on.
- 20,000 lines of functions in a single file, 50% of which was unused, mostly repeated code that could have been reduced massively.
- Zero Code Comments
- Inconsistent variable names, function names, file names -- I was literally project searching for months to find things.
- There is nothing close to a normalized SQL Database, column ID names can't even stay consistent.
- Every query is done with a mysqli wrapper to use legacy mysql functions.
- Most used function is to escape stirngs
- Type-hinting is too strict for the code.
- Most files packed with Inline CSS, JavaScript and PHP - we don't want to use an external file otherwise we'd have to open two of them.
- Do not use a package manger composer because he doesn't have it installed.. Though I told him it's easy on any platform and I'll explain it.
- He downloads a few composer packages he likes and drag/drop them into random folder.
- Uses $_GET to set values and pass them around like a message contianer.
- One file is 6000 lines which is a giant if statement with somewhere close to 7 levels deep of recursion.
- Never removes his old code that bloats things.
- Has functions from a decade ago he would like to save to use some day. Just regular, plain old, PHP functions.
- Always wants to build things from scratch, and re-using a lot of his code that is honestly a weird way of doing almost everything.
- Using CodeIntel, Mess Detectors, Error Detectors is not good or useful.
- Would not deploy to production through any tool I setup, though I was told to. Instead he wrote bash scripts that still make me nervous.
- Often tells me to make something modern/great (reinventing a wheel) and then ends up saying, "I think I'd do it this way... Referes to his code 5 years ago".
- Using isset() breaks things.
- Tens of thousands of undefined variables exist because arrays are creates like $this[][][] = 5;
- Understanding the naming of functions required me to write several documents.
- I had to use #region tags to find places in the code quicker since a router was about 2000 lines of if else statements.
- I used Todo Bookmark extensions in VSCode to mark and flag everything that's a bug.
- Gets upset if I add anything to .gitignore; I tried to tell him it ignores files we don't want, he is though it deleted them for a while.
- He would rather explain every line of code in a mammoth project that follows no human known patterns, includes files that overwrite global scope variables and wants has me do the documentation.
- Open to ideas but when I bring them up such as - This is what most standards suggest, here's a literal example of exactly what you want but easier - He will passively decide against it and end up working on tedious things not very necessary for project release dates.
- On another project I try to write code but he wants to go over every single nook and cranny and stay on the phone the entire day as I watch his screen and Im trying to code.
I would like us all to do well but I do not consider him a programmer but a script-whippersnapper. I find myself trying to to debate the most basic of things (you shouldnt 777 every file), and I need all kinds of evidence before he will do something about it. We need "security" and all kinds of buzz words but I'm scared to death of this code. After several months its a nice place to work but I am convinced I'm being pranked or my boss has very little idea what he's doing. I've worked in a lot of disasters but nothing like this.
We are building an API, I could use something open source to help with anything from validations, routing, ACL but he ends up reinventing the wheel. I have never worked so slow, hindered and baffled at how I am supposed to build anything - nothing is stable, tested, and rarely logical. I suggested many things but he would rather have small talk and reason his way into using things he made.
I could fhave this project 50% done i a Node API i two weeks, pretty fast in a PHP or Python one, but we for reasons I have no idea would rather go slow and literally "build a framework". Two knuckleheads are going to build a PHP REST framework and compete with tested, tried and true open source tools by tens of millions?
I just wanted to rant because this drives me crazy. I have so much stress my neck and shoulder seems like a nerve is pinched. I don't understand what any of this means. I've never met someone who was wrong about so many things but believed they were right. I just don't know what to say so often on call I just say, 'uhh..'. It's like nothing anyone or any authority says matters, I don't know why he asks anything he's going to do things one way, a hard way, only that he can decipher. He's an owner, he's not worried about job security.13 -
Dependency Injection Frameworks are absolute shit. I have yet to encounter one that doesn't make code take hours to understand or debug, and usually requires a debugger to even begin to unravel it. Not to mention the "context" god objects that just are glorified versions of passing an array from function to function. You guys aren't avoiding global state you're just making it a clusterfuck. Stop being stupid for 2 minutes software development "progress" challenge. Level: impossible.19

So, first time ranting, sorry if I mess anything up.
When I first started my current job and got introduced to the system we were coding in, something seemed a little fishy to me. Didn't like the system anyway, but at least the language is a compiler language, so it runs quite quickly, right?
In theory, yeah. If the lead dev liked the IDE that came with it. But he has to REALLY fucking hate it, because rather than using it, he codes in plaintext. No syntax highlighting, no auto-indent, nothing. And he's built the entire damn system around doing that. Sadly the compiler is only integrated into the IDE, so what do we do there? Copy the code from the plaintext file to the IDE to compile it there? No no, why would you. The language has a function you can use to compile some code at runtime.
And so he does. Every. Single. Fucking. Script. There's a single main script that runs and finds the correct textfile to then runtime-compile and execute. So we effectively made a compiler language into a massively unoptimized interpreter lang.
I even mentioned that this might be a problem, but I was completely dismissed, so at that point it's not my problem anymore and I have then switched to a different system anyway.
Couple weeks later I heard the same guy complaining that the scripts were running almost the whole night so we'd probably need some better hardware or something.
Well if only there was a really obvious solution that would improve the performance by probably about a factor of 20 or so...13 -
Anyone who has experienced this without falling into desperation deserves a beer, I know I need one.
Colleague: Python says I have an indentation error, halp. *Sends screenshot*
You: okay, it says it's located on file.py line 39. Can I see the related line?
Colleague: *sends a screenshot of the whole file, without numbered lines*
You: ummm, could you send me the related lines tho?😐
Colleague: 😒 yeah. *Resends a screenshot of the error and the whole file...again*
You: I REALLY need you to send me only the function scope to help you cuz I can't visually debug the whole file on a picture.
Colleague: *sends a panned phone picture with an arrow to the function (half of it)*
Plot twist: she's your girlfriend.

GF: I can't see it, I'll go have a snack.1 -
Just got a new job at an old school hardware company. The codebase is giving me heart attack. They don't care about dev experience or code navigation at all. Every attempts to modernize the codebase is so half assed. All patches are so bloated that make the codebase even worse.
Frontend is migrated from prototype-oop-jquery cluster fuck to AngularJS, then finally angular. Holy moly, all business logics are baked into UI "classes" using prototype chain. When they migrated to AngularJS, someone simply added a wrapper to that jQuery cluster fuck class and overwrote all the prototype with a 10k +lines file. Since all the methods are hidden in either prototype, JS object, or callback function, it's impossible to trace the data pipeline using IDE when "go to definition" on update() method gives you all the update methods/string in all objects/classes. And they don't care about immutability. References are taken out, renamed, and mutated everywhere. Finding the source of a bug is fucking guessing game.
I don't know what trick they use that makes cLion static analyzer fail.
And there is no unit test or spec doc.
Fuck me dead3 -
Helped a friend who's currently learning programming in Java
Looked at the slides used to teach them and apparently the teacher explains the "static" keyword as "can be accessed from any function of the class"... Which... Isn't at all what static does
At that point they hadn't started with actual OOP stuff, so I kind of get why they didn't explain what it really does, but why the fuck did they just put down a completely wrong definition?! Instead of just saying "yeah you'll just need that keyword for now, I'll explain it later"19 -
Joined a new team at work 6 months ago. Immediately set upon by a useless PO who was somehow set in her ways while still being around 30 years old. Absolutely refused to change the broken team dynamic or processes in any way whatsoever. Made terrible tickets, never did refinement on tickets so they were always missing stuff and constantly blocked. Generally unlikeable and difficult to work with, incompetent at her job and resolutely refused to change literally anything to make the team function better.
She finally leaves after 6 months and the team dynamic changes immediately. Suddenly we are improving our processes, getting stakeholder input, refining tickets, taking reasonable amounts of work in a sprint. We have discussions without her butting in and getting frustrated when you bring up legitimate concerns. No longer do you have to tiptoe around and appease her ego if you want to point out the obvious flaws in the work she drew up or even just examine it from a technical perspective.
It's insane how much things can improve once you shed the dead weight of people that are just determined to be difficult and won't budge an inch to change their ways. Good riddance.4 -
Elon musk has shown himself to be a terrible person, a worse manager and someone who hasn't a clue of what a code review is. A summarily fires so many people that he can't find someone to open the doors for his big in person meeting or the vet the badges. He offers 3 months termination pay or you can work 12 hours a day 7 days a week hardcore. But none of the payroll people are around anymore either. Critical subsystems have not a single engineer left to work on them. He's paranoid that employees will sabotage the software. But I think he's doing such a good job it would be impossible to tell that anyone else was helping him.
An engineer wrote a prescient seven page report listing problems ahead including user verification. So Elon twit-fired him.
Also entirely predictable is the stress that the world cup will put on the system beginning today, I believe. He doesn't "like" microservices.
I work for the psychiatrist once who barely needed to sleep. Maybe Elon can function with 12-hour days week in week out. But it's cool to think you're going to squeeze substantially more work out of people by doubling their hours. More likely you will more than double their errors and what will that do to you budget? 50 years ago IBM determined that the best way to improve programmer productivity was to give each one their own office.
I can't believe he's whining over spending 13 million dollars a year on food. That is so far from being a strategic item. Soapbox out.28 -
This whole programming profession sucks! Programmers suck! Managers suck! Companies suck! Products suck!
Why is it so hard to organize your stupid code at least a bit?! No, it’s not deadlines, just write a block of code and give it a meaningful name, a function, a method, a comment, so many options, so little fucks given. Give things a meaningful name instead of whatever came to your mind that moment. There’s no excuse! No, just leave it to the next guy, and he’ll leave his trash for another one. And then we complain and make memes about it. Fuck you all!
There’s no purpose or vision of products, managers sweep problems under a rug, executives do whatever they do, as long as some money is pouring in, just keep pedaling semi-mindlessly. Spin the wheel you little hamsters until you drop, there’s enough hamsters out there.
It’s just a clusterfuck of small, selfish interests and egos, a mud of meaningless and unnecessary problems that need not be there.
It’s not the workload, it’s the stress! The stress of bullshit, and constant problems that can be avoided if everyone did their job at least half-professionally. Not just programmers, everyone!6 -
CTO: We'll use epochs for any time related fields in our services.
After service integration...
Dev from producer team: Hey the time field is showing up as 1970 and not null in your table. That seems to be a bug.
Me: Code looks fine. We are converting epochs to timestamps here. Null is taken care by the library function itself.
The same dev: Actually we are sending zero instead of null values in that time field. But we'd want the end table to treat that as null.
Me: Why can't you send null then?
The dev: Actually avro doesn't support nulls. Hence the zero.
Me: WTF??????
Manager to me: Actually you need to convert them as null. Anyways, this is not a blocker and we can live with it for now.
END OF RANT
Why can't they fucking send it as null? And when I asked about the details, that particular event type doesn't require that field. Still the manager insists on sending that field for it.22 -

I work in a big German company and we are a lot of teams building the company website.
Obviously the website is in German but almost all the devs are not German speakers, included the testers.
To make the work easier in the frontend we use sometimes the translation function of chrome and it's funny because a lot of time I got a bug opened by a tester for a wrong label because HE FUCKING FORGOT TO DISABLE THE TRANSLATION AND HE THINKS THAT THE LABEL IS IN THE WRONG LANGUAGE1 -
I have adhd and anxiety which means I cant smoke, drink coffee or drink alcohol because that fucks up my sleep and short term and long term memory badly for few days in a row. ADD symptoms become unmanageable. Fuck my life. I guess I will have to cut all stimulants if I want to be abe to function as a decent dev. I will have to cut most of my social circle because they wont understand me not going out for drinks... Fuck my life....14

Programming has given me an insight into the inner workings of the system that defines every aspect of the modern world. I will never ever be able to look the same way at a game, website, elevator, microwave, the synced traffic lights in a city or really anything that resembles mathematical structure and was built after 1990. Seeing how my friends appreciate all these for their function I often feel like I'm missing out, but I guess they feel the same when the machines don't act as expected.2

Someone created a 0-followers private Twitter account and posted something to try out the new views count feature.
It raked dozens of views in a couple hours.
HOW?!?
Source: https://twitter.com/briggityboppity...
It looks like a funny data reverse-engineering exercise, so let's try and figure out what is going on.
Hypothesis 1) it is the OP's own views.
Reasonable, but unlikely if what OP says about not checking it for hours is true.
H2) It's some background job in OP's device that is refreshing OP's own latest tweets, so even without human interaction technically H1 is true. It would be some really shoddy engineering to count eye-less page views, but that's also what managers would demand.
H3) it's some internal Twitter automated function like back up, replication, indexing and word count.
See H2, it would be even dumber to count that as page views.
H4) it's some internal human reviewing for a keyword that could be associated with porn (in this case, "butts"). Really? dozens of humans to review a no-impact single post? They would have to employ hundreds of thousands of reviewers.
H5) it's some page-loading shit, like thousands of similar tweets get stored in the same index hash page and end up counting as a view in all of them every time someone loads the index page. It would be like counting every hit in the namenode as a hit in every data asset in it's Hadoop partition, or every hit in a storage block as a hit in each of it's files.
Duuuumb and kinda like H3.
H6) page views are just a fraud to scam investors. Maybe it's a "most Blockchain transactions are fake" situation, maybe it's a "views get more engagement if you don't think a lot about it" situation, maybe it's a "we don't use the metric system to count page views" situation.
All of them are very dumb.
Other hypothesis or opinions?10 -
Today, for the first time since I've started coding, I had a legitimate use case for the multi-cursor feature of my IDE in reasonably DRY code.

A certain person here on devRant was annoyed about my phone being named “Beyond”, seeing a screenshot of my settings.
What they said: “the name, beyond, reeks pretentiousness and arrogance, you say you’re better than other people”
What really happened: during one of my manic episodes, I discovered the band named Death Grips. Their music resonated with me and helped me to cope with my derealization. In one of their songs, I misheard lyrics, and heard the word “Veyon” that was never there in the first place. Upon my inner voice pronouncing it, as it usually happens to me, a brand-new universe appeared before me, where Veyon was a name of a megacorporation that exists in a shaky spacetime plane somewhere in India. If you want to go there, three outcomes are possible: you can actually come to their building that appears to be normal, with people working inside you can talk to, and no signs of trouble in sight. Or, you can try to walk to their building, but you will never reach it. GPS will show you slowing down gradually as you get closer, but to you, it would look like you’re just walking with your regular speed, as if nothing happened. Like a function trying to reach its asymptote, you’ll never come to your destination. The third outcome is by far the most interesting one. You will reach the building, but it will be abandoned, with doors scattered on the floors randomly, some of them will disappear after you walk in, rendering you missing in this universe. Oh, and floors are guarded by robots and turrets, and they are made by Grumman, the military aviation manufacturer. Yes, Grumman, not Northrop Grumman. This building in the third outcome originates from the spacetime plane where Northrop and Grumman never merged.
The whole thing raced through my mind in a millisecond. I liked it and decided to squat the name, but it was already taken by Veyon open source software (Virtual Eye On Networks).
In some time, I bought a new phone second-hand, and named it Veyon. The next day, I took it to shower with me. It turned out that the seller lied to me about it never being fixed. It was, and in the process its water resistance was compromised. So, this phone was damaged beyond repair the next day I bought it.
The same day, I went and bought the same phone model, but brand new, and in black, as I originally wanted. I was grateful for this opportunity that helped me escape the situation where I would've been using the phone of the colour I disliked just because I cheapen out. I know myself, and I would’ve been feeling uneasy every day, hesitant to sell it and get a new one because “nothing is wrong with it, quit being this picky, it’s just a colour”, but wait, don’t I deserve to make the colour a significant enough reason to switch the phone because I care about colour, especially if it’s me who’s paying the money? Did I make this money rightfully, or am I an impostor who gets paid because of intricate lies I tell? Do I actually tell them, or do I make that up to somehow convince "them" I'm innocent? Or do I try to get attention?
I’m terrible at dealing with that kind of mess, So, I was grateful.
The only thing left to do was to name my new phone. I decided not to name it “Veyon” again, just in case. So, I named it “Beyond”, as this word is probably what the actual song said.
The monstrosity of a story above is the usual thing for me to feel. I was really hurt by you telling me the name I chose was a display of pretentiousness. Do I deserve to be pretentious? I say yes, but my voice is shaking, as flashbacks of my awful mother abusing me come in the way.
You hurt me with that comment. Let’s meet? :)2 -
I swear to god "old school" C++ devs are menace to humanity
Why yes let's make this one line long function, that could even be constexpr, and make it a macro.
Why the fuck not, let's make compiler errors worse by foregoing any type checking. Let's throw away namespacing as well, great.
Fuck you.
I shouldn't have to dig through 4 levels of nested macros just cause "muh performance" and "we've always done it like that".

Around a decade ago, I was fiddling with ajax in jQuery. This piece of code had me stumped for around 2 days, why? Because success is written with 1 final S in my native language...
$.ajax({
'succes' : function(data) { },

So I met this person via a social platform.
They were absolutely silly and weren't able to hold a conversation. So I, like a normal person, just stopped trying to keep things alive.
Over the years, I have realised and learnt that if a person is interested in being friends, they'd put in efforts and I alone will not have to drag things on my shoulder.
I started cutting out people right, left, and center who I felt were taking advantage of me or using me in some way or another.
I ended up saving a lot of time and energy. I no longer feel drained or anxious about something not working out. Not dragging saved me from draining.
Anyway, they reach out to me again after few weeks and I was like let's give it a try to establish a friendship, because befriending people is my weak point.
The cycle repeats. At first I thought it must be because of the asynchronous nature of the platform so I drop my Telegram Id in case they preferred an IM approach.
I swear in the name of sweet lord, the retard does the same behaviour. So, I stopped communication.
And one fine day, the person tells me that they lack social skills and want to learn how to make friends and stuff.
Very fair point. So, me being me, gave them a few tips and critically pointed out their behaviour on how they reply with a one liner after every 2 or 3 business days.
Absolutely no change in their behaviour. They kept texting me the same.
At this point, I was like why am I doing it? I could find better people easily. Because for me, communication is everything. I cannot function without a good communication between two living beings.
So, I asked them why are they even trying to learn social skills when they barely implement it and don't want to change to which they reply saying that so they can use it to befriend people and network to getter better job opportunities.
I fuck them off.
And fuck such people who have intentions, are not clear enough about it, and play people for their own selfish gains.
And this where another learning I got from @scout is have boundaries.
Why do all good people in my life leave? Damn it! I need those good people back and be friends with them and not retards who cannot even communicate beyond one liner.11 -
It's weird and scary how fragile we humans are. Somedays, I'm well collected, I know my worth, I contribute to generate some value and some other days, I feel like a complete loser, can't contain a thought in my head, can barely function properly, ...

Fucking legacy projects
This is why I drink on the weekends4 -
So about two months ago in my consulting firm I was asked to replace a colleague on a project (node and Angular). The project is only a few months old but it’s already a total clusterfuck. DB is very poorly designed. It’s supposed to be a relational database but there’s not a trace of a foreign key or any key for that matter and I’ve seen joins like tableA.name = tableB.description (seriously, that’s your relation??). The code is a mess with entire blocks of code copied from another project and many parts of the code aren’t even used. He didn’t even bother renaming variables so they would make sense in the context they were shamelessly thrown into. The code is at best poorly typed if not typed at all.
During our dailies I sometimes express my frustration with my other colleagues as I very politely allude to my predecessor’s code as being hard to work with. (They are all “good friends" with him). I always get the same response from my colleagues: "yeah but you’ve gotta understand Billybob was under a lot of pressure. The user stories were not well defined. He didn’t have time to do a proper job". That type of response just makes me boil inside.
Because you think I have time to deal with this shit? You don’t think I’m working with the same client and his user stories that are barely intelligible? How long does it take to write type definitions for parameters going into a function? That’s right, 30 seconds at most? Maybe a minute if it’s a more elaborate object? How much time do you think you’ll save yourself with a properly typed function or better yet an interface? Hard to tell but certainly A LOT MORE than those 30 seconds you lost (no, the 30 seconds you INVESTED) in writing that interface!!!
FUCK people with their excuses! Never tell me you don’t have time to do a proper job! You’ve wasted HOURS of my time just because you were too fucking lazy to type your functions, too lazy to put just a little more thought into designing your tables, too lazy to rename a variable so that it’s name actually makes sense where it’s being used. It’s not because you were short on time. You’re just lazy!
FUCK!!!!!!4 -
Holly crap..... Just fixed a 7 months old bug in a system i worked on and had to leave it for 7 months coz i just wasn't seeing what i did wrong and today..... everything simply unraveled
It's a flask app and i got stuck on updating a column in the database and also it created duplicate configs on one of the configuration functionality
Figured out what was causing duplicates
A different function was creating new configs instead of updating...bypassing duplicate checking in the config function2 -
Me: *changes a long and complex calculation to fix old mistakes*
Program: *keeps outputting the same wrong result*
Me: *goes mad for a good hour trying to discover the problem by debugging it like a angry rat*
Also me after one hour of debugging: *discovers he never changed the output source of the function and it's still outputting the old result*3 -
So.. I'm giving one of my employers webapps a visual refresher, new company branding and whatnot.
And then I stumbled onto a check that is not returning what anybody expects, and, well , I'm busy fixing things, yeah..? so I go digging.. 🤔
```
function isDefined(obj) {
return !(typeof obj === "undefined") || obj !== null;
}
```
Here's the fun part, these particular lines have been in the code base since before 2017, which is when my Git history starts, because that's when we migrated projects from Visual SourceSafe 6 over to Git. Yes, you read that right. They were still using VSS in 2017.
I've begged and pleaded with my last 3 bosses to let us thrown this piece of shit out our second story window and rewrite it properly. But no, we don't have time to rewrite, so we must fix what we have instead.
I lost 4 hours of my life earlier today, tracking down another error that has been silently swallowed by a handler with its "console.log" call commented out, only to find that it's always been like that, and it's an "expected error". 🤦
Please, just fucking kill me now... I just, I can't deal with this shit anymore.5 -

Fuck Wordpress, Fuck Wordpress's PHP
I'm so fucking tired of everything in this godforsaken CMS. Import a JS File? Sure, just add a *completely obvious* line into a very specific PHP File, where you'll have to specify a lot of "useful" parameters. No, I somehow DON'T want to specify that I don't wand jQuery in every import. And don't even get me started on Content Delivering. Embed CSS? Sure, just write the fucking whole path to the file, or use the broken get_stylesheet_uri() Function. Embed an Image? Sure, let me just go to the Backend and wait 6 Minutes for this bullshitty System to upload the image and then copy the hard-coded Link. Oh, you want to remove googleapi embeds? Sure, let me just fuck up your whole Website in return.
You want jQuery? Well instead of using the "$" Symbol, you have to use the jQuery() Function. Except when you don't have to, which is 100% random each time you reload the page. Oh, you actually did import a JS File? Sure, let me just not run it. Thank you fucking piece of shit thats calling itself "WordPress" and fuck you and everyone whos actively encouraging its usage1 -
In 2015 I sent an email to Google labs describing how pareidolia could be implemented algorithmically.
The basis is that a noise function put through a discriminator, could be used to train a generative function.
And now we have transformers.
I also told them if they looked back at the research they would very likely discover that dendrites were analog hubs, not just individual switches. Thats turned out to be true to.
I wrote to them in an email as far back as 2009 that attention was an under-researched topic. In 2017 someone finally got around to writing "attention is all you need."
I wrote that there were very likely basic correlates in the human brain for things like numbers, and simple concepts like color, shape, and basic relationships, that the brain used to bootstrap learning. We found out years later based on research, that this is the case.
I wrote almost a decade ago that personality systems were a means that genes could use to value-seek for efficient behaviors in unknowable environments, a form of adaption. We later found out that is probably true as well.
I came up with the "winning lottery ticket" hypothesis back in 2011, for why certain subgraphs of networks seemed to naturally learn faster than others. I didn't call it that though, it was just a question that arose because of all the "architecture thrashing" I saw in the research, why there were apparent large or marginal gains in slightly different architectures, when we had an explosion of different approaches. It seemed to me the most important difference between countless architectures, was initialization.
This thinking flowed naturally from some ideas about network sparsity (namely that it made no sense that networks should be fully connected, and we could probably train networks by intentionally dropping connections).
All the way back in 2007 I thought this was comparable to masking inputs in training, or a bottleneck architecture, though I didn't think to put an encoder and decoder back to back.
Nevertheless it goes to show, if you follow research real closely, how much low hanging fruit is actually out there to be discovered and worked on.
And to this day, google never fucking once got back to me.
I wonder if anyone ever actually read those emails...
Wait till they figure out "attention is all you need" isn't actually all you need.
p.s. something I read recently got me thinking. Decoders can also be viewed as resolving a manifold closer to an ideal form for some joint distribution. Think of it like your data as points on a balloon (the output of the bottleneck), and decoding as the process of expanding the balloon. In absolute terms, as the balloon expands, your points grow apart, but as long as the datapoints are not uniformly distributed, then *some* points will grow closer together *relatively* even as the surface expands and pushes points apart in the absolute.
In other words, for some symmetry, the encoder and bottleneck introduces an isotropy, and this step also happens to tease out anisotropy, information that was missed or produced by the encoder, which is distortions introduced by the architecture/approach, features of the data that got passed on through the bottleneck, or essentially hidden features.4 -
Got back at work after 2 weeks off
Useless to say I did not remember what to do or where to start…

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 am java dev with 5 yoe at a place which has really good engineering talent.
Was assigned a feature request.
Feature request requires me and one more older dev(in age, not in exp at company) to write the code. My piece is really super complex because of the nature of the problem and involves caching, lazy loading and tonne of other optimization. Naturally it makes up 90% of the tasks in the feature request. On the other hand, the older dev simply has to write a select query (infact he only needs to call it since a function is already written).
Older dev takes up all the credit, gives the demo, knows nothing but wrongly answers in meetings with higher ups and was recently awarded employee of qtr.
It looks as if I do the easy work whereas he is the one pulling in all the hard work.
Need advice to justify my work and make others realise it's significance, nuances of area and complexity of it.
Do not expect monetary benefits, just expect credit and recognition for the worth of work I am doing.12 -

Yet another reason to design my own keyboard..
I get the most expensive keyboard out there, and guess what, it stops working correctly when it collects a bit of dust and hair..
Meanwhile my 35 year old IBM Model M, you could eat on it for 10 years and it would still function just fine !
My new keyboard, the roller wheel starts to act up, no problem, I'll just take it apart and clean it..
Once I find all the hidden screws with odd sized screw heads..
And then find out you can't take it all apart easily to gain access to the parts you want to clean.
And then find out, the parts you do want to clean, don't seem to come apart for cleaning..
Lets drip some cleaning fluid there anyhow and hope for the best !
That worked, for now..
So badly designed !
Oh did I mention how its a split keyboard, and the addon part doesn't have a locking mechanism, so you need to use blutak to hold it together..
Who designs this shit !
And that is before I mention how windows updates screwed with the keyboard settings so I suddenly got bounce issues !
It's supposed to be a bounce free keyboard !
And it doesn't work in my BIOS because its USB.. ( Even though USB is supposed to be supported.. )
So, why doesn't someone design a USB and PS/2 keyboard !
Did I mention how the keyboard font is too small to read without glasses..
Or how the back lit keys bleed light all over the place, and don't just shove iit through the keytops.
And, now my iii is acting up repeating itself..
My IBM model M was never like this !
But it isn't backlit..
Nor does it have a left handed numberpad..
But then, this doesn't have a real left handed numberpad, its just a right handed one on the left side, so my thumb is in the wrong place !
Apart from that, its fine...
Oh, except, don't use the app that comes with it, or rather, don't leave to runnning, or it crashes your PC..
But its fine to set up the keyboard with. :-)25 -
Fucking egos. Why is it so difficult to communicate with some senior?
Senior: we need to support old browsers.
Me: What about using polyfills.ts?
Senior: that's not what I am asking for. what's wrong with my implementation?

Senior: is the pr breaking some features for old browser...

Salesforce lightning web components have such bullshit limitations that they claim is because of security but it's just because it's overengineered garbage.
Want to use web components? Nope.
Want to pass in a value to a function in a click listener expression? Nope.
Want to use scss? Nope, compile it to css yourself.
Want to use the fucking document object? Guess what it's overridden except for very specific third party frameworks.
Who in the fuck thought it was a good idea to override the document object? Your app isn't more secure, literally the entire internet uses the document object and it still becomes available in runtime anyway so what the fuck??
LWC is the biggest garbage I've ever seen, you know a framework's a big red flag when there are developers solely for the framework.
There is a new security release coming out that apparently removes some of these nuances (understatement) so there might be some light at the end of the tunnel.4 -

Maybe I'm severely misunderstanding set theory. Hear me out though.
Let f equal the set of all fibonacci numbers, and p equal the set of all primes.
If the density of primes is a function of the number of *multiples* of all primes under n,
then the *number of primes* or density should shrink as n increases, at an ever increasing rate
greater than the density of the number of fibonacci numbers below n.
That means as n grows, the relative density of f to p should grow as well.
At sufficiently large n, the density of p is zero (prime number theorem), not just absolutely, but relative to f as well. The density of f is therefore an upper limit of the density of p.
And the density of p given some sufficiently large n, is therefore also a lower limit on the density of f.
And that therefore the density of p must also be the upper limit on the density of the subset of primes that are Fibonacci numbers.
WHICH MEANS at sufficiently large values of n, there are either NO Fibonacci primes (the functions diverge), and therefore the set of Fibonacci primes is *finite*, OR the density of primes given n in the prime number theorem
*never* truly reaches zero, meaning the primes are in fact infinite.
Proving the Fibonacci primes are infinite, therefore would prove that the prime number line ends (fat chance). While proving the primes are infinite, proves the Fibonacci primes are finite in quantity.
And because the number of primes has been proven time and again to be infinite, as far back as 300BC,the Fibonacci primes MUST be finite.
QED.

So I'm on orders for the Marine Corps, and this one guy thinks he's a programmer because he made a "program" in excel for dispatching our equipment. He's complaining that he's just fixing bugs. I take a look at his VBA code and see literally 1000 lines of if statements bundled into one function. (Or I think they're referred to as sub routines in VBA - it's been a while since I worked with it).
I try to give him some tips and pointers since he's literally just manually checking. Each. F'ing. Cell and a million nested if statements. Tried giving tips on making reusable code, and he has the cojones to tell me he knows what he's doing and doesn't need my "help". Granted I'm higher ranking than him and he also answers in a disrespectful manner.

Is the CS field creating terms for the sake of creating terms?
Someone mentioned a "closure" in another post. I instinctively knew what they meant by that based upon the code I saw. I had heard the term thrown around before, but it had not yet connected in my mind. I wondered why I had not been exposed enough to care.
So I thought: What does C++ have as far as closures?
I found that C++ has lambdas. Those are definitions for function objects. They do not exist at runtime. But a closure does. The analog is you have classes. They are definitions and do not exist at runtime. But instances of classes do. So at runtime the instance is what you are working with. This is the same as lambdas vs closures in C++. The closure is the runtime counterpart. Why a separate term for what essentially is an instance? Is it because it captures data and code? As far as I know the closure is all data that gets passed around that calls a function. So it is essentially an instance of a lambda.
Another term: memoization. I have yet to see this added to any dictionary in online tools like a browser. Is the term so specific that nobody cares to add it? I mean these are tools programmers use all the time.
My guess is these terms originated a long time ago and I have just not been exposed to the contexts for these terms enough. It just seems like I feel like I have been in the field a long time. But a lot of terms seem alien to me. I also have never seen these terms used at work. Many of the devs I work with actively avoid CS specific terms to not confuse our electrical coworkers. My background started in electrical. So maybe I just didn't do enough CS in college.6 -

Was working on a system we planned on to deliver to a hospital
basically it was meant for controlling and monitoring pactions coming in and attendance time from the staff
Got it off the ground well and got to where the system was supposed to update room status
occupied/free then horror started
the db was not setting the room free after clearing a client off the list... room remained occupied and this kept on happening for 6 months and I was so focused on fixing the db models thinking thats where the problem was....
1 day after leaving the project for several months i just revisited the project randomly and started going through the whole code base trying to make sense of what was happening as there where no errors generated..
I had to verify the whole system logic... and that day i figured out what was happening...
upon adding a client to a room the system was also creating a duplicate room so when the function for setting the room free executes it would set the duplicate room free and not the actual room and the system would pick the room with occupied state causing the user not being able to assign new pactions to the room
Solving this brought so much relief coz it required so much work just to solve what seemed to be a minor issue6 -
In several occasions I run rm -rf * in the wrong folder (or wrong server!!).

I implemented the equivalent of “?.” In typescript with a function callled safeRetrieve(descend into the field only if the object is not null).

Looking for platform specific language options for a new project at work and reading articles from well known sources.
If you start your article with something like, "when I think of a good programming language, I think of JavaScript", I'm going to punch out of your shitty opinion faster than an async function.

Oh my god, GDScript is the single biggest piece of shit scripting language I have ever witnessed. It somehow manages to combine the very worst things of dynamic typing with the downsides of static typing, all in one bundle of utter shit
Imagine you have two game object scripts that want to reference each other, e.g. by calling each others methods.
Well you're outta fucking luck because scripts CANNOT have cyclic references. Not even fucking *type hints* can be cyclic between scripts. Okay no problem, since GDScript is loosely based of Python I can surely just call my method out of the blue without type hints and have it look it up by name. Nope! Not even with the inefficient as fuck `call` method that does a completely dynamic-at-runtime fuck-compile-time-we-script-in-this-bitch function call can find the function. Why? Because the variable that holds a reference to my other script is assumed to be of type Node. The very base class of everything
So not only is the optional typing colossal garbage. You cant even do a fucking dynamic function call because this piece of shit is just C++ in Pyhtons clothing. And nothing against C++ (first time I said that). At least c++ lets me call a fucking function7 -

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 -
Testing every little class and stateless function is a brilliant way to spend a lot of time doing nothing.
At the same time, if I didn't have to test it, I probably wouldn't have turned it into tiny classes and mostly stateless functions.2 -

typescript - I needed to learn it for a project and I like it, I know java and javascript and it is something in between of those two that makes writing enterprise web applications easier, it’s nice that you can debug it directly in chrome, it makes things easier
Worst
docker, Dockerfiles - devops tools - amount of shell commands inside them and mangled && to make everything running in one file layer makes those unreadable mess that you need to think twice to understand, there is no debugger for it, you do everything with try and see what happens, there is actually no real dev toolset for devops and that sucks, since you got builder images that makes things more mangled than before, it’s clearly missing some external officially approved scripting language or at least
FUNCTION and
WITH LAYER and indentation / parentheses syntax and they still trying to make it flat, why are you doing that ?
as a result next to Dockerfile cause you can’t import multiple ones you get bunch bash scripts with mangled syntax and other crap that is glued together to make a monster - and this runs most of current software on this planet2 -

I've been working with Golang for a while now and I've come to love the generics they introduced. Making stuff type-safe is a bit of a hassle, but it pays off greatly.
One thing I had yet to consider though, is that functions are also a type, so that those could be made generic too.
func DoThing[F func(string) | func(int)](callback F) {...}
Now you can deliver both function types and I can differentiate them using a type switch.
Weird that sometimes my brain doesn't make that connection immediately...1 -
Just started Online Banking at my bank. Checked how much money I have and what I can do on the website.
Afterwards I opened the dev tools and see that there is a js warning. So I open the console and the fucking first thing I see is: Loglevel set to INFO. WHAT THE FUCK?!?
Other things I found out:
API Endpoints are logged here. Two deprecation warnings for a function used. A warning about a deprecated service used.
The log level is now set to WARN. Several more deprecation warnings for the framework from before.
The fuck is this?12 -
I did not think that making a serverless Discord bot would be such a learning experience. The code itself was easy. The hard part was the infrastructure, because I decided to automate it all with Terraform and deploy it on AWS.
Before this project, I had no idea how API Gateways worked. Now I still have very little idea how they work but I managed to build one anyway. Eventually. And then I had to figure out how to automate the deployment of a lambda layer and function that would both still be managed in the Terraform state, with any code changes triggering a rebuild and update for the resource.
And then I had to untangle a dependency mess because API Gateways have some weird issues where two resources that have no explicit dependencies on each other will throw an error if they don't deploy in the right order.
And then I went the wrong way with Github actions trying to conditionally chain multiple workflows together before I realized I could just put multiple jobs with conditions in a single workflow.
And now after all that work over the course of 2 days, I have a bot that does this:2 -

So I see posts about an interview question/challenge of inverting a binary tree. I don't use trees very often (mainly file related or parsing server nodes), but I thought I would learn how to do this.
I saw a page that started talking about different ways to invert enough to understand that one type of inversion is swapping left and right nodes. So I stopped before they showed how.
Then I created a test program that has a tree structure and also can display a tree before and after modification. This was kind of fun.
So then I wrote the inversion function. It was less than 10 lines of code. Wtf? I thought it would be harder than this.
Then I started wondering where trees were used. So today I have been learning how they are used and why I might need one to solve a problem. One use I intuited was parsing regex or a language. Apparently it is useful there.
What I am learning is that a lot of these interview questions are really test to see if you can comprehend instructions when stressed. Or you will ask questions to clarify the task. It doesn't necessarily test your ability to solve hard problems.
One thing that perplexes me. If inverting a tree is swapping nodes left<->right, then why not leave data in place and just swap roles in the functions. Maybe I completely misunderstood what inversion means or why it would be done. I guess if this is not inverting I have the structure to try other methods now.2 -
Can we take a moment to recognize how absolutely retarded JS' event system is?
Events aren't objects. No, they're managed by an object, and identified by a string.
To subscribe to an event, you call object.addEventListener(name, callback). Because for some reason we can't just have an event object. Events MUST have an owner.
But to unsubscribe you don't call the function addEventListener returned, you don't use the token it returned either. No, you pass the same function to removeEventListener.
Because we don't use serializable tokens like in PP, and we don't return functions like in FP, no, we use functions as tokens, realising idiomatic DFP.2 -
Mathematics feels like a giant old undocumented codebase in that, yes you could read the comments of each function, you would rather have a nice complete, well formatted docs page that in human terms explains how things work together, why they are here and where they came from.13

#Story time.
Been working on a project for 2 months with Colleague "Jim" doing the code reviews. Project is finished in a stable form and can be extended if needed. Then my other colleague/boss "Mo" decided that we need to do a refactor. Fast forward a bit and the conclusion is "Mo" and "Jim" are going to discuss every step with me. And we started a new project that should do the same as the project I just finished
Here some facts:
Every day a meeting/ code review / discussion.
Decisions they make I do not agree with.
I need to redo my work multiple times.
Now this does make me look like a toddler that needs supervision which is not the case.
They want something future proof and something that fits his new coding standard "Mo". and certain things I do agree with and is clearly the better architecture. however somethings are just stupid, time wasting, making it worse. I'm getting so frustrated by the fact that billion dollar companies have clear coding standards that work. and are correct. and this company decided to do their own thing of stupid rules!
- shorten variables
- Keep lines under 90char
- put multiple things in 1 file
- Keep function names short

I can now appreciate some design decisions behind react-redux after witnessing some angular OOP clusterfuck.
I am sure there is some clean/correct way to code in angular, but everyone is treating angular as java.
Some angular application (the one I have to work with) is littered with network calls. It's difficult to spot duplicates. People usually resolve promises everywhere. In services, in a top-level component, or in for loops. In react, people use apollo/redux-query or redux-saga to handle network calls. Since these libraries prevent duplicate network calls internally and reassigning apollo network call function or redux action function is always useless, it's easy to spot all network calls in a component tree.
In angular, it's difficult to trace data mutations when data can be updated everywhere. In react, you can easily find UI state updates by tracing state hooks/dispatch/apollo usages.
In angular, it's difficult to trace data pipeline. Since everything is imperative by default, people need to add update functions in data subscriptions. With all the littered mutations. Soon you will lose track of what the fuck is going on.
I hope angular get the agonizing death it deserves and fuck everyone who codes JS OOP clusterfuck UI.11 -
Imagine you're in a company, one year in now. You've tried your best to amass as much knowledge of legacy services as you can (specially given no documentation) and you think you've done the best you can.
Now imagine your manager is upset that you haven't gotten as much domain knowledge as an engineer who's been in the team for five years now. Then also imagine that your manager whenever asked about specific product or tech or any knowledge on a service just keep tagging the 5 year engineer. If he ever gives an update in slack on any incident, he doesn't read what everyone has written in the channel so far, but invites the team on a call, and asks them to verbally tell him what to write as an update so as to show he actually understands it all and is showing leadership. What do you do?
Also I've read a good manager let's his team self function without any micromanaging but I feel this is literally hypocritical (lack of knowledge comparison) and useless of him to essentially making no decisions or understanding anything without pointing fingers. What would you all do about this kind of manager, or am I just inexperienced and maybe not seeing what he's actually doing and contributing. -

Data wrangling is messy
I'm doing the vegetation maps for the game today, maybe rivers if it all goes smoothly.
I could probably do it by hand, but theres something like 60-70 ecoregions to chart,
each with their own species, both fauna and flora. And each has an elevation range its
found at in real life, so I want to use the heightmap to dictate that. Who has time for that? It's a lot of manual work.
And the night prior I'm thinking "oh this will be easy."
yeah, no.
(Also why does Devrant have to mangle my line breaks? -_-)
Laid out the requirements, how I could go about it, and the more I look the more involved
it gets.
So what I think I'll do is automate it. I already automated some of the map extraction, so
I don't see why I shouldn't just go the distance.
Also it means, later on, when I have access to better, higher resolution geographic data, updating it will be a smoother process. And even though I'm only interested in flora at the moment, theres no reason I can't reuse the same system to extract fauna information.
Of course in-game design there are some things you'll want to fudge. When the players are exploring outside the rockies in a mountainous area, maybe I still want to spawn the occasional mountain lion as a mid-tier enemy, even though our survivor might be outside the cats natural habitat. This could even be the prelude to a task you have to do, go take care of a dangerous
creature outside its normal hunting range. And who knows why it is there? Wild fire? Hunted by something *more* dangerous? Poaching? Maybe a nuke plant exploded and drove all the wildlife from an adjoining region?
who knows.
Having the extraction mostly automated goes a long way to updating those lists down the road.
But for now, flora.
For deciding plants and other features of the terrain what I can do is:
* rewrite pixeltile to take file names as input,
* along with a series of colors as a key (which are put into a SET to check each pixel against)
* input each region, one at a time, as the key, and the heightmap as the source image
* output only the region in the heightmap that corresponds to the ecoregion in the key.
* write a function to extract the palette from the outputted heightmap. (is this really needed?)
* arrange colors on the bottom or side of the image by hand, along with (in text) the elevation in feet for reference.
For automating this entire process I can go one step further:
* Do this entire process with the key colors I already snagged by hand, outputting region IDs as the file names.
* setup selenium
* selenium opens a link related to each elevation-map of a specific biome, and saves the text links
(so I dont have to hand-open them)
* I'll save the species and text by hand (assuming elevation data isn't listed)
* once I have a list of species and other details, to save them to csv, or json, or another format
* I save the list of species as csv or json or another format.
* then selenium opens this list, opens wikipedia for each, one at a time, and searches the text for elevation
* selenium saves out the species name (or an "unknown") for the species, and elevation, to a text file, along with the biome ID, and maybe the elevation code (from the heightmap) as a number or a color (probably a number, simplifies changing the heightmap later on)
Having done all this, I can start to assign species types, specific world tiles. The outputs for each region act as reference.
The only problem with the existing biome map (you can see it below, its ugly) is that it has a lot of "inbetween" colors. Theres a few things I can do here. I can treat those as a "mixing" between regions, dictating the chance of one biome's plants or the other's spawning. This seems a little complicated and dependent on a scraped together standard rather than actual data. So I'm thinking instead what I'll do is I'll implement biome transitions in code, which makes more sense, and decouples it from relying on the underlaying data. also prevents species and terrain from generating in say, towns on the borders of region, where certain plants or terrain features would be unnatural. Part of what makes an ecoregion unique is that geography has lead to relative isolation and evolutionary development of each region (usually thanks to mountains, rivers, and large impassible expanses like deserts).
Maybe I'll stuff it all into a giant bson file or maybe sqlite. Don't know yet.
As an entry level programmer I may not know what I'm doing, and I may be supposed to be looking for a job, but that won't stop me from procrastinating.

When engineers get so CS-driven they can’t see simple things 🙃
Another manager messaged me and my boss last night to ask whether he’ll have to expose a certain function to be available in objective c classes (we’re iOS devs and most of our code is in swift, but some older stuff is still in .m files). He said he dug into the lower level code and didn’t see any connections or exposures so he assumes he’ll have to add these. My boss concurred and told him to go ahead and make them available.
Then I showed up with my didn’t go to university brain & searched the codebase for calls to that function from .m classes. There were like a hundred lol, working just fine. It’s already exposed. Neither of them thought to do that.2 -
OOP is so ass, classes that extend classes that need objects, of classes that extend classes , passend to their constructor which constructs an object to be given to a constructor of a class that extends a class that implements three interfaces.

It's a shame that people don't want to use F# but prise C# for how cool it became and continue becoming. At the same time, little do they know that many of the features were simply drawn from F#.
It's just rediculous how far this OO and C-Style syntax crap has progressed. They keep copying things from functional langugages, making the initial language to be a monstrocity like C++ is now, insted of just using languages like C#. I mean, it was right there before C#: async/task, immutablility, records, indexes, lambdas, non-null by default, who the hell knows what else.
Besides, many people (in my company at least) are just blindly overengineering with patterns and shit, where a simple function would be just enogh.
Watch some some NDC talks about F#, in particular those of Scott Wlaschin. It's just better in so many ways: less noice (I'm looking at you, brackets, commas and semicolons), the whole LOT of type inference and less duplication (just look at the C# signatures of linq methods - it's difficult to read them), immutability by default, non-nullable by default, ADTs and pattern matching, some neat features like type providers (how many times have used "paste special" or an online tool to create C# classes from a JSON/XML file, and how many times have your regenrated it because of schema changes?) and units of measure.
Of course, in some cases it's not optimal, in some cases mutable datastructures of C# are better for performance. But dude, how many performance critical systems have you wrote in C#? I mean, if it comes to performance you should use Rust or C++ or C after all.

I've been working with Node and Typescript for a while now, and I wrote a wide array of very general utility functions. Examples include:
- Array.filter but you also get the residue array, it can also leave holes in both arrays if you want to join them later
- Array zipping and unzipping to and from tuples (especially valuable when you're manipulating the prop set with Object.entries() in a HOC
- Array maximum selection, with an optional mapper
- Cancelable promises, lazy promises, a promise that resolves when a given function on an object is called (excellent for DOM events), a timeout promise.
- A typed event with both immediate and microtask listeners depending on whether you need state guarantees (this idea I took from a Github gist and upgraded it)
I want to put them on NPM so I don't have to write them and their tests again, and so that if I ever think of an improvement it's easier to propagate it. Do you think I should release them as tiny individual packages which would be nice from a versioning standpoint, or should I make them into a compilation which would be a lot less work for me (and therefore would probably result in better documentation and more tests)?4 -
Anyone tried converting speech waveforms to some type of image and then using those as training data for a stable diffusion model?
Hypothetically it should generate "ultrarealistic" waveforms for phonemes, for any given style of voice. The training labels are naturally the words or phonemes themselves, in text format (well, embedding vectors fwiw)
After that it's a matter of testing text-to-image, which should generate the relevant phonemes as images of waveforms (or your given visual representation, however you choose to pack it)
I would have tried this myself but I only have 3gb vram.
Even rudimentary voice generation that produces recognizable words from text input, would be interesting to see implemented and maybe a first for SD.
In other news:
Implementing SQL for an identity explorer. Basically the system generates sets of values for given known identities, and stores the formulas as strings, along with the values.
For any given value test set we can then cross reference to look up equivalent identities. And then we can test if these same identities hold for other test sets of actual variable values. If not, the identity string cam be removed, or gophered elsewhere in the database for further exploration and experimentation.
I'm hoping by doing this, I can somewhat automate the process of finding identities, instead of relying on logs and using the OS built-in text search for test value (which I can then look up in the files that show up, and cross reference the logged equations that produced those values), which I use to find new identities.
I was even considering processing the logs of equations and identities as some form of training data perhaps for a ML system that generates plausible new identities but that's a little outside my reach I think.
Finally, now that I know the new modular function converts semiprimes into numbers with larger factor trees, I'm thinking of writing a visual browser that maps the connections from factor tree to factor tree, making them expandable and collapsible, andallowong adjusting the formula and regenerating trees on the fly.7 -

As much as i love kotlin, i hate that you dont have static functions like in java. You have to put them in a companion object or write them in extension functions outside of the class.
Also when working with generics (lets say T) you cant call T::class.java unless you are in an inlined function and mark T as refeied. This is not the case in java i think. I havent checked.1 -
Two years ago we took over this project which has been a nightmare to maintain. It's a set of netcore 2.1 webapps running on an on-prem windows machine. Everyone who has worked on it so far has quit, leading to two episodes of it being passed on with near zero handover.
Its function is fairly simple, so naturally we have been nagging to redo it and cloudlift it.
I was finally given one week to see how far I'd get, and had a poc running in Azure after one day; 4 apps in clean net6, SSO, and managed identities. The only thing lacking was setting up the authentication for third parties.

We had a dispute @ work yesterday on this topic :
aproach 1 :
$res = getSomeData( [ 'filter_1' => 'str_1', 'filter_2' => 'str_2', ... 'limit' => 10 );
with
function getSomeData( $data )
{
...
}
VS
aproach 2 :
$res = getSomeData( 'str_1', 'str_2', ... 10 );
with
function getSomeData( $filter_1 = '', $filter_2 = 'default_str', ... $limit = 20 )
{
...
}
I had used 1-st b/c IMHO it's more dynamic and easy to maintain and call ( especially when there are many params, most of which not used on each call )
and my colleague didn't liked it w/h his main arguments that one can not easily see the needed params and no default vals for them ( the latest could be easily corrected in the function body ). I'm curious to read your opinions, arguments & contra arguments for each aproach13 -
It's nice that more and more languages are introducing async/await syntax, but by the example of Rust in particular I'm starting to wonder why we don't instead introduce this syntax for monads in general?
We could have a keyword (say, `bind`) which unwraps a value from any monad provided that the return value of the function is wrapped in the same monad. The ? operator does something a little similar, and I'll be intrigued whether it can actually be implemented for monads other than Result and Option once GATs are stabilized. In particular in the case of Rust, it would be possible to create a reference counting monad for heap-bound management of objects derived from references.9 -
Looking further into Rust, the macros are quite sexy. My first reaction was "omg really"? But then I learned that macros in Rust are nothing like macros in C++.
Again, comparing with my favorite language Swift, it feels like Rust macros are somewhat similar to result builders (formerly named function builders). Or they they have a similar purpose. Both evaluate to some type safe result at compile time and are a perfect tool to make DSLs.
But Rust’s macros can do even more than that. It’s truly amazing.2 -
I love Typescript's challenges. Today I had to make a generic interface that replaces every property in its parameter with either itself, a promise of itself or a different property keyed `obtain${key}` which is a function returning either the value or a promise of it. Not a very difficult challenge, but it was very satisfying to solve.
If anyone has the patience to attempt it I'm very curious what more experienced type theorists than myself come up with.1 -
So, just to recap if you missed the last few episodes. I've been a web developer for years. But I decided to get a degree and go to uni.
Also I am firmly on the fewer comments side of the debate about self-documenting code. Even though I usually rephrase it and say method and variable names are comments. Basic idea: something is unclear, you should leave a comment. But, before you leave a comment, take a good look at your method. Can you rename a variable? Maybe the method name? Maybe extract a method into smaller methods so it doesn't need a comment? And only if you fail to do so, leave a comment.
Alright, now that we rehashed that, uni coding makes no bloody sense.
There is code that is abbreviated to the max (or min).
And then, they need everything commented. I mean, why do that? Why call the parameters a and b instead of base and exponent. And then say:
"But write a whole article about it above the method". Like:
a is the base for a power operation.
b is the exponent for a power operation.
return int representing a to the power of b
How about just do this:
public static int power(int base, int exponent).
How is this not the same documentation?
Is it because we're at a uni, a place for smart people and smart people shouldn't have an issue keeping a mental map between the variables and their meaning?
Or is it because they are all mathematicians. All respect to applied mathematics. I mean, the function about exponent calculation, I was not aware that it could be that effective. But on the other hand, keep mathematicians away from programming. I get it, writing maths per hand doesn't have intellisense and therefore you don't want to write long variable names. It's and old tradition. Yada yada, yah.
But programming is not maths. And maths shouldn't be maths like that. Right naming makes it simpler. It might still be a while until we all LaTeX rather than handwrite and be able to give maths right naming schemes, but programming is beyond the point. Calling the array you handing in a function A and the one that you're returning D makes no fucking sense.4 -

I am reading rfc7635 and its references, but they refer to functions they don't define properly and rely on cryptography jargon by eg. calling values by different names, so I'd appreciate a reference implementation of the function for building tokens to clear up the confusion.

Anyone know why calling the "memo" function on a React component or using the "useMemo" hook is widely accepted to be called "memoization", when the name itself derives from an existing English verb which actually means what the function does? Why are we artificially creating jargon?6

Getting the angular interceptor working the way I want has proven to be a pain for me. I try to update an auth token, which returns a promise that has to be transformed to an observable again. based on that, redirect to a login page, in case of 401. But nothing works! Either infinite page reload because of the login() promise function of the auth provider or no reaction at all after a router redirect. 😤4

I want to share one of my recent interview experience..
so first round was telephonic and technical guy seems cool as he did not emphasis on syntax, function name etc.. but just took the info of my tech on which I am working on and discuss some approaches to find a solution towards the problem.. ( I guess thats pretty well for experienced dev)
Second round was assignment and its a hell of assignment :( atleast for me.. Like I work in CI 3 and I did assignment on CI 4. almost everything is changes in CI 4 ( I mean its structure writing the way of routes,models and controllers).. But I took the challenge personally and finished 95% of assignment ..
Overall this interview experience was pleasant one.. :) -
I was troubleshooting an asyncio websocket project for two hours that was working the previous day with minimal changes.
I am new to asyncio so I was getting very frustrated thinking I wasn't understanding something.
As it turns out, I had replaced a continue with a return, killing the broadcast function completely. -
My two main grudges against Typescript:
1) Union types can't be passed as arguments if there is a variant for every element of the union
2) No tuple polymorphism, i.e. [T, U] isn't assignable to [T]. This is not a mistake because the length of the arrays differs and therefore they may be interpreted in a different way, but IMO there should be a tuple type which is actually an array but length is unavailable and it supports polymorphism. This sounds stupid, but since function parameter lists work well with tuples it would actually enable a lot of functional tricks that are currently inaccessible.7 -
So am I the only one that hates everything about the new Teams update? Tbf, the zooming function is cool. But I just want to use full screen.7

Heres a fairly useless but interesting tidbit:
if i = n
then
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
then r%a will (almost*) always return 0. when n = floor(a/2) for the lowest non-trivial factor of a two factor product.
Thats not really the interesting bit though. The interesting bit is the result of r will always be some product with a *larger* factor tree that includes the factor A of p, but not p's other larger factor, B.
So, useless from what I can see. But its an interesting function on its own, simply because of what it does.
I wrote a script to test it. For all two-factor products of the first 1000 primes, (with no repeating combinations, so if we calculated say, 23*31, we skip 31*23), only 3262 products failed this little formula, out of half a million.
All others reliably returned 0 for the following..
~~~
i = floor(a/2)
r = (abs(((((p)-(9**i)-9)+1))-((((9**i)-(p)-9)-2)))-p+1+1)
r%a
~~~
The distribution of failures was *very* early on in the set of factors, and once fixed at the value of 3262, stopped increasing for the rest of the run.
I didn't calculate if some primes were more likely to cause a product to fail or not. Nor the factor trees, nor if the factor trees had any factors in common between products, or anything of that nature.
All in all I count this as a worthwhile experiment.
If you want to run the code yourself, I posted it to pastebin here:

When people write functions/methods with bodies smaller that the call header (-_- ).
Function calls are not free people! Just Inline that shit manually (or at least make sure the compiler does so)!

God people undoing good work that made a property function correctly drives me fucking nuts
Wtf is wrong with you stupid fucking people ! Do you all want to live in fucking trash heaps ???72 -
Typescript is my new favorite and my grudge is the stupid scoping of type assertions. I have an async function that checks whether a variable is set and awaits a change event if it's undefined. This function is working javascript but invalid according to typescript, because it relies on the exact type changing while the function is running. I had to convert it to a mess of promises to bypass this because (and this is the best) the callback-based syntax of identical meaning will reset all type assertions, even locals that are never written after the callback's creation.8

Anytime I write a line of code that works correctly the first time, I’m ecstatic. If I write a whole block or function that works right the first time, I freak out with happiness. Yes, I’m that bad at coding. The rest of y’all probably do such things on the regular and it no biggie. But for me, it’s vanishingly rare.

I implore ANYONE... please...
Have you EVER written a SINGLE Jest test that didn't have some sort of bullshit spewing stuff like this:
"ReferenceError: You are trying to `import` a file after the Jest environment has been torn down."
"Warning: React.createElement: type is invalid -- expected a string (for built-in components) or a class/function (for composite components) but got: object. You likely forgot to export your component from the file it's defined in, or you might have mixed up default and named imports."
and yet running on a device, features work flawlessly and quite well, no errors or even warnings in sight logged
This is the most fragile pile of garbage I have ever seen.
I hate this.
inb4 your stupid ass todo boilerplate garbage you wrote tests for in freshman year. i'm talking about a REAL app with HUNDREDS of components.
where the grownup testing tools at? it's a question I've still not answered after a year of fucking around with this framework2 -
You people do know all this added reorganized convenience in some places if left alone would have made things so easy if the other aspects hasn't been subtle acted by some fags
Less horror more function !2 -
At work thres a legacy "common" DLL, which held a helper function that's incharge of creating Slugs, it takes an MD5 of the current time stamp UTC, removing non-URLable chars, and taking the first N chars that remain then
Ngl I was impressed at first at it, but then I thought, its Uniqueness isnt guaranteed
But then again I thought, the uniqueness can be tested via a call given it's indexed anyway in DB so O(1), and if non-unique, just re-call the function. Even in the worst case scenario the hits won't be that many anyway
I didnt change the code, tho at first I was inclined to given my "it isnt proven-unique" stance but am wondering, if this is a good approach
While coolish, it seems wrong in the back of my mind somehow...1 -
I recently refactored a form with complex client side interactivity for one of my clients replacing jquery with vuejs in the process and I'm absolutely baffled by how easier it is to reason about everything when you think of the UI as a function of the state. Only devs who have done both imperative and declarative DOM manipulation at some point in their life can understand the joy of doing this. And all of this can be done with just a simple script tag without having to bring in complex build process that has plagued the Javascript ecosystem.

create two function one for finding factorial of first 6 prime numbers and another for storing prime numbers and their factorial in two separate arrays. call both the function inside the main function.write a c++ code for solving this problem and displaying the all desired output.5

I can't google jargon, what do you call it when you "flip" a function call, such that the call becomes an event in some dispatch system and return becomes a call on the event? I had to implement five such APIs this week with surface level differences and I'm starting to feel like it has to have a name if it's this popular.
For the pedantic, I mean async calls in JS in particular, I know you can't just invert a synchronous function call that uses a stack without peek.6 -
Does anyone here use any nootropics, either at work or on personal projects? About to have an extra busy few months and I'm looking for some recommendations.5

Have an object that uses a macro to define its function bodies. I needed to interface to that object in a different way. So I wrote and object that calls functions on that object and presents a different interface. I used macros to define the function bodies...

I have JUST realized the word “ease-in-out” is not a palindrome! The function itself is, and I was SURE the word was a palindrome too. I just _knew_ it. Fuck.
Fun fact: “()()” is also not a palindrome.3 -
having a DSA interview in 2 days, any suggestions on how/what to prepare?
its been years since i tried solving coding problems with anything apart from strings or arrays( and that too the one we use in dev, like writing a function to convert string to uppercase, that's all i remember)
There are a million algorithms: knapsac, djikstra, DFS BFS, bellman ford, TRIE, BST, quick sort, merge sort, insertion , binary search... these are some buzz words i could remember from my early college days, 6 years ago. I was able to understand and learn them at that time, but now i know shit about them :/
How to go with all of these in 48 hours?6 -
Drawing pictures in your mind. This is something I have always struggled with.
Is there a set of exercises a person can do to develop imagery in your mind?
I have had times when I closed my eyes that I experienced what I would call imagery that rivaled or was more detailed than what my eyes fed me. But I only experienced this and did not create what was in the imagery. It has only been once or twice. I know that when I start to dream I can start seeing things with imagery, but I still cannot control this directly. I had one lucid dream where I woke in my dream and was able to construct things for a short period.
What I would like to be able to do is construct shapes and diagrams in my head. Perhaps visualize how an algorithm might function.
Is there a way to learn this?5 -
line breaks after 100 or so characters suck. function chaining will look bad in one line, but it doesn't mean we need to limit all our lines to a hard length.
ex:
config.logger.e(TAG, "func() called with: p1 = $p1, p2 = $p2, p3 = $p3, p4 = $p4, p5 = $p5")
this is a standard log that i add at the start of my functions . its easy to autogenerate in intellij , even if my class and variable names are much long (like mVideoAnalyticsManager) . when these variables and their string names add up, they will easily go out of the screen and i won't mind scrolling a few seonds to the left to ensure everything is correct (which 99.9% is)
but a fucking ctrl+alt+l and all strings are broken with a fucking +

I have the following scenario with a proposed solution, can anyone please confirm it is a secure choice:
- We have critical API keys that we do not want to ship with the app because de-compiling will give access to those keys, and the request is done before the user logs in, we are dealing with guests
Solution:
- Add a Lambda function which accepts requests from the app and returns the API keys
- Lambda will accept the following:
1. Android app signing key sha1
2. iOS signing certificate sha1
- If lambda was able to validate them API keys are sent back.
My concerns:
- Can an attacker read the request from the original (non-tampered) apk and see what the actual sha1 value is on his local network?
- If the answer to the question above is yes, what is the recommended way to validate that the request received is actually from the app that we shipped and not from curl/postman/script/modified version of the app11 -
So I've been forced to work on a project for some time using JavaScript
Many parts of it must function synchronously and js has a lot of libs and otherwise that will spawn threads in threads
I'm horrified by the amateurish appearance of my code
Await this await that
Everything enclosed in something else and what is worse is the base node modules I'm using are ALL asynchronous! Were talking methods that one consistently has to wait on finishing like db reads !
Why is js so dumb ?26 -

4 hours wasted due to a rather strange "scope poisoning" bug... it was really fucking strange.
Had to move the 5 lines of code, above where the error happened, to a private function.
The 5 lines just called an XLSX library which read a given file and returned an array. I don't know how but the thing somehow messed with my Soap client call one line below. The culprit must have been some IO resource handle which didn't get destroyed when in the same scope due to persisting object references..1 -
Hi, guys!
Maybe some of you can help me with React?
So I'm still learning React SM to make mini projects for practice and this is for project daily expenses and the mockup is attached. So, if i want to add an item, i want to match it with the current date and compare it with the last entry date, I'm confused here how to make the function.1 -
hey devos, I got a question to ask ya'll. I have an interview tomorrow with an MNC.
I was hovering through some leetcode problems when I came across a hard question that is forcing me to use a hashmap with the key of the user-defined type. I made up my mind to make use of C++ for the coding interview. Now, the problem is C++ asks me to implement a hash function.
If in case, I'm asked a similar question like this in the interview, which of these two options will you suggest:
a) implement your own hash function
b) use pointers as key2 -
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 -
There's a special place hell for people who put their entire documentation on using an NPM package in the fucking READ.ME file.
I shouldn't have to play whack a mole through one giant ass file to figure out how a specific function works. Or figure out how specific optional parameters need to be defined.3
