So I told my wife one week ago: "Yeah, you should totally learn to code as well!"
Yesterday a package arrived, containing a really beautiful hardcover book bound in leather, with a gold foil image of a snake debossed into the cover, with the text "In the face of ambiguity -- Refuse the temptation to guess" on it.
Well, OK, that's weird.
My wife snatches it and says: "I had that custom made by a book binder". I flip through it. It contains the Python 3.9 language reference, and the PEP 8 styleguide.
While I usually dislike paper dev books because they become outdated over time, I'm perplexed by this one, because of how much effort and craftsmanship went in to it. I'm even a little jealous.
So, this morning I was putting dishes into the dishwasher, and she says: "Please let me do that". I ask: "Am I doing anything wrong?"
Wife responds: "Well, it's not necessarily wrong, I mean, it works, doesn't it? But your methods aren't very pythonic. Your conventions aren't elegant at all". I don't think I've heard anyone say the word "pythonic" to me in over a decade.
And just now my wife was looking over my shoulder as I was debugging some lower level Rust code filled with network buffers and hex literals, and she says: "Pffffff unbelievable, I thought you were a senior developer. That code is really bad, there are way too many abbreviated things. Readability counts! I bet if you used Python, your code would actually work!"
I think I might have released something really evil upon the world.29 -
Sad story about refactoring.
Programmer: I cleaned up the codes, extract reusable methods, reduced repetitive code and improve overall readability and maintainability.
Manager: why the page still display the same.
Programmer: ...7 -
Code: if(customer.primaryContract)
Boss: "just using a variable as a boolean isn't very readable"
Me:
if(!(!customer.primaryContract != !true).toString() == 'false')13 -
Manager: Why are you always refactoring?
Me: Refactoring keeps the codebase's entropy in check :)
Manager: mind blown!!

HOW THE FUCK AM I SUPPOSED TO USE THIS DAMN BRAINFUCK LIBRARY WITHOUT PROPER DOCUMENTATION.
THIS ENTIRE LANGUAGE WAS CLEARLY INTENDED AT READABILITY, SO STOP TRYING TO TAKE THAT AWAY.
YOU MOTHER FUCKING BRAINFUCK DEVS, PLEASE WRITE CLEARLY EXPLAINED, PROPER DOCS.
GOODNIGHT.7 -
I had a coworker used to write PHP pages in this way:
<?php
echo "<html>";
echo "<head>";
// 2000+ lines of un-indented nightmares
I tried suggesting him to keep the HTML outside php tags as much as possible and I stressed out that adding some indentation to the code would have improved readability. I also sent him an example of my code created using an IDE with auto-indent functionality.
His creepy answer was: «Readability is subjective. Anyway I'll try to get used to the sinusoidal trend of your code.»11 -
if( !condition ) vs. if(condition == false)
Pointless debate started with readability, turned into heated insults under 30 seconds 😂20 -
PineScript is absolute garbage.
It's TradingView's scripting language. It works, but it's worse than any language I have ever seen for shoddy parsing. Its naming conventions are pretty terrible, too:
transparency? no, "transp"
sum? no, cum. seriously. cum(array) is its "cumulative sum."
There are other terrible names, but the parser is what really pisses me off.
1) If you break up a long line for readability (e.g. a chained ternary), each fragment needs to be indented by more than its parent... but never by a multiple of 4 spaces because then it isn't a fragment anymore, but its own statement.
2) line fragments also cannot end in comments because comments are considered to be separate lines.
3) Lambdas can only be global. They're just fancy function declarations. Someone really liked the "blah(x,y,z) =>" syntax
4) blocks to `if`s must be on separate lines, meaning `if (x) y:=z` is illegal. And no, there are no curly braces, only whitespace.
There are plenty more, but the one that really got me furious is:
98) You cannot call `plot()`, `plotshape()`, etc. if they're indented! So if you're using non-trivial logic to optionally plot things like indicators, fuck you.
Whoever wrote this language and/or parser needs to commit seppuku.17 -
New guy at work asks me for a code review. 16 lines added, and I have 4 comments, all about readability. Only the major stuff because I went easy on him. I even ignored a missing semicolon.
Guy comes to me and explains that code review is about if code works, not what it should look like. "You want me to write it your way, and we'll have endless arguments if that's how you do code reviews. But I'll do your requested changes." Reduces his entire code to two lines, which make a lot more sense.
Later, I ask him why he used "void 0" anyway. I was wondering if he's thinking of security aspects or if there's another reason. His answer: "because it looks cool and nobody else does it". -
Kotlin: I don't have ternary operator, it's bad for readability
Swift: I removed ++ and --, cause they are old fashioned
Dart: *screams*
23 -
Why is the ternary operator such a hated thing? I constantly hear people saying it's less readable, confusing, etc.
I think it's a beautiful, useful, and important operator and I use it constantly wherever readability won't be much affected.
How can you justify a repetitive if/else structure over a ternary, given that you're sure you're not going to put anything else in the ifs?
Whatever happened to DRY?
Whatever happened to KISS?
If those guidelines are what you code by, what's the excuse not to use it?
Because you can't read it as well? Familiarity breeds comprehension and legibility, my dudes.15 -
So my team lead told me in a code review that you shouldn't use 'else if' in code.
Instead you should best them like:
if
else
if
else
if
else
Apparently that would improve readability...
Am I crazy, or what?18 -
Been reviewing ALOT of client code and supplier’s lately. I just want to sit in the corner and cry.
Somewhere along the line the education system has failed a generation of software engineers.
I am an embedded c programmer, so I’m pretty low level but I have worked up and down and across the abstractions in the industry. The high level guys I think don’t make these same mistakes due to the stuff they learn in CS courses regarding OOD.. in reference how to properly architect software in a modular way.
I think it may be that too often the embedded software is written by EEs and not CEs, and due to their curriculum they lack good software architecture design.
Too often I will see huge functions with large blocks of copy pasted code with only difference being a variable name. All stuff that can be turned into tables and iterated thru so the function can be less than 20 lines long in the end which is like a 200% improvement when the function started out as 2000 lines because they decided to hard code everything and not let the code and processor do what it’s good at.
Arguments of performance are moot at this point, I’m well aware of constraints and this is not one of them that is affected.
The problem I have is the trying to take their code in and understand what’s its trying todo, and todo that you must scan up and down HUGE sections of the code, even 10k+ of line in one file because their design was not to even use multiple files!
Does their code function yes .. does it work? Yes.. the problem is readability, maintainability. Completely non existent.
I see it soo often I almost begin to second guess my self and think .. am I the crazy one here? No. And it’s not their fault, it’s the education system. They weren’t taught it so they think this is just what programmers do.. hugely mundane copy paste of words and change a little things here and there and done. NO actual software engineers architecture systems and write code in a way so they do it in the most laziest, way possible. Not how these folks do it.. it’s like all they know are if statements and switch statements and everything else is unneeded.. fuck structures and shit just hard code it all... explicitly write everything let’s not be smart about anything.
I know I’ve said it before but with covid and winning so much more buisness did to competition going under I never got around to doing my YouTube channel and web series of how I believe software should be taught across the board.. it’s more than just syntax it’s a way of thinking.. a specific way of architecting any software embedded or high level.
Anyway rant off had to get that off my chest, literally want to sit in the corner and cry this weekend at the horrible code I’m reviewing and it just constantly keeps happening. Over and over and over. The more people I bring on or acquire projects it’s like fuck me wtf is this shit!!! Take some pride in the code you write!16 -
In our morning stand up, dev was bragging about how much code he was refactoring (like over-the-top bragging) and how much the changes will improve readability (WTF does that mean?), performance, blah blah blah. Boss was very impressed, I wasn't. This morning I looked at the change history and yes, he spent nearly two solid days changing code. What code? A service that is over 10 years old, hasn't been used in over 5, mostly auto-generated code (various data contracts from third party systems). He "re-wrote" the auto-generated code, "fixed" various IDisposable implementations and other complete wastes of time. How –bleep-ing needy are people for praise and how –bleep-ing stupid are people for believing such bull-bleep? I think I should get a t-shirt made with a picture of a BS-Meter and when he starts talking, “Wait a sec, I gotta change my shirt. OK…you were saying?”

Why in the flying motherfuck can't people remember the fact that other people might have to read their code?! If you're not gonna name things properly, and mess everything up with utterly useless and garbage comments (all comments are useless and garbage), then the least you can do is fucking format and indent it properly!! GAWD FAKKIN' DAMNIT!!4
-
Well, if your tests fails because it expects 1557525600000 instead of 1557532800000 for a date it tells you exactly: NOTHING.
Unix timestamp have their point, yet in some cases human readability is a feature. So why the fuck don't you display them not in a human readable format?
Now if you'd see:
2019-05-10T22:00:00+00:00
vs the expected
2019-05-11T00:00:00+00:00
you'd know right away that the first date is wrong by an offset of 2 hours because somebody fucked up timezones and wasn't using a UTC calculation.
So even if want your code to rely on timestamps, at least visualize your failures in a human readable way. (In most cases I argue that keeping dates as an iso string would be JUST FUCKING FINE performance-wise.)
Why do have me parse numbers? Show me the meaningful data.
Timestamps are for computers, dates are for humans.3 -
I've been working towards a degree in CS recently after being out of school nearly 10 years. I've been trying really hard to keep an open mind and not complain about the professors, but I have to let this out.
My one class we have to write all of our code in their specified editor which I hate, but I understand the need for standardization, but then once it is error free we have to copy and paste the code into ms word and turn it in!! Really?! In 2018 I can't just submit my source files and you open them to run and grade? I seriously have to copy my code into ms word for you to grade it? I don't even understand how you would grade that because it kills the formatting and readability, not to mention the quotes get changed to their curly counterpart which isn't valid syntax.7 -
SICK AND TIRED OF READABILITY VS. EFFICIENCY!!!!!!!
I HAD TO SEPARATE A 4 LOC JSON STRING, WHICH HAD AN ARRAY OF A SINGLE KEY-VALUE PAIRS (TOTAL OF 10 OBJECTS IN THE ARRAY).
ITS READABLE IF YOU KNOW JSON. HOW HARD IS TO READ JSON FORMAT IF YOU GET YOUR STYLE AND INDENTATION PROPERLY?!?
SO I HAD TO
BREAK THE POOR FREAKING JSON APART TO A FUCKING DIFFERENT YAML FILE FORMAT ONLY SO I CAN CALL IT FROM THERE TO THE MAIN CONTROLLER, ITERATE AND MANIPULATE ALL THE ID AND VALUES FROM YAML BACK TO MATCH THE EXPECTED JSON RESPONSE IN THE FRONT END.
THE WHOLE PROCESS TOOK ME ABOUT 15 MINUTES BUT STILL, THE FUCKING PRINCIPLE DRIVES ME INSANE.
WHY THE FUCK SHOULD I WASTE TIME AT AN ALREADY WORKING PIECE OF CODE, TO MAKE IT LESS EFFICIENT AND A SLIGHTLY BIT MORE READABLE?!? FML.5 -
Me: We should use typescript to enhance our readability and productivity.
Senior dev: No... We don't want to use any other languages except JavaScript.
(A month later)
Too many catch, race conditions and hidden bugs left. 5 hours of debugging16 -
I need to stop sacrificing readability for smaller amounts of code. What looks good to me isn’t always best for everyone and that’s a fucking tough pill to swallow.4

Making python 2x faster by replacing enums with literal values.
Pros, it's faster, cons, it's unreadable.
God I miss compiled languages. At least optimizing them requires intelligent problem solving.
It's a text parser state machine transition so it's a code hot spot, so this kind of optimization is worthwhile. But it's kinda annoying.
Next is get rid of any semblance of readability and replace the match with an array index...31 -
Hey Python, why in the ever loving readability universe I can't break the following command across multiple lines?
df.replace(...).apply(...).reset_index().drop(...)
Oh, but I hear you say "Hitko, why you can break it into multiple lines if you break within brackets!"
To which I ask you, does this shit look any more readable?
df.replace(...
).apply(...
).reset_index(
).drop(...)15 -
Okay so I have been a consumer of devRant for a while now but never posted anything. This is my first.
So yesterday I modified an existing method(some very minor changes!!). Today after coming to the office I see that I have comments from Sonarqube stating
"Reduce cognitive complexity from ** to 15.
I get that it is a good measure to maintain readability but this refactoring is not part of my change at all and any mishap can break the whole code base!!!.
My code even won't build because of this company restriction that there should not be any issues from Sonarqube.
I really want to bash my head against the wall right now.11 -
So my dear programming teacher really hates break statements... I mean really really really. He thinks it's better for readability if you don't break from any kinds of loops (not even ifs) well then we came across a switch statement in class. He says "breaks only exist because it's needed in switches" well how about returning from a fcking swith? or goto? then you need no break...
Is there anyone who could explain why I should NEVER use breaks and why it's bad in any piece of code? Why is it better to just use whiles because fors are apparently evil again? Srsly I just wanna ask him to show me some big code bases without breaks...8 -
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 -
Lessons I've learnt so far on programming
-- Your best written code today can be your worst tomorrow (Focus more on optimisation than style).
-- Having zero knowledge of a language then watching video tutorials is like purchasing an arsenal before knowing what a gun is (Read the docs instead).
-- It's works on my machine! Yes, because you built on Lenovo G-force but never considered the testers running on Intel Pentium 0.001 (Always consider low end devices).
-- "Programming" is you telling a story and without adding "comments" you just wrote a whole novel having no punctuation marks (Always add comments, you will thank yourself later for it I promise).
-- In programming there is nothing like "done"! You only have "in progress" or "abandoned" (Deploy progressively).
-- If at this point you still don't know how to make an asynchronous call in your favourite language, then you are still a rookie! take that from me. (Asynchronous operation is a key feature in programming that every coder should know).
-- If it's more than two conditions use "Switch... case" else stick with "If... else" (Readability should never be under-rated).
-- Code editors can MAKE YOU and BREAK YOU. They have great impact on your coding style and delivery time (Choose editors wisely).
-- Always resist the temptation of writing the whole project from scratch unless needs be (Favor patching to re-creation).
-- Helper methods reduces code redundancy by a large chunk (Always have a class in your project with helper methods).
-- There is something called git (Always make backups).
-- If you don't feel the soothing joy that comes in fixing a bug then "programming" is a no-no (Coding is fun only when it works).
-- Get angry with the bugs not the testers they're only noble messengers (Bugs are your true enemy).
-- You would learn more than a lot reading the codes of others and I mean a lot! (Code review promotes optimisation and let's you know when you are writing macaroni).
-- If you can do it without a framework you have yourself a big fat plus (Frameworks make you entirely dependent).
-- Treat your code like your pet, stop taking care of it and it dies! (Codes are fragile and needs regular updates to stay relevant).
Programming is nothing but fun and I've learnt that a long time ago.6 -
The senior dev in my team wants me to convert all the lambda expressions I have written to anonymous inner classes. He says it will increase the code readability.
IT IS NOT MY FAULT THAT YOU CAN'T READ LAMDA EXPRESSIONS!!!!
It's like the dev has something against the new features of Java87 -
!rant, TL;DR at the bottom
Holy fuck, Yesterday, I got absolutely schooled by a literal newbie.
And I mean, NEWBIE newbie, the dude just started a Computer Science degree, and has been learning Java only for a MONTH. He has 0 prior experience with code or anything of the like, and he's somewhat of an Ars(Israel's version of a Gopnik).
So I was helping him with some stuff he didn't understand, and lo and behold his code was probably the most aesthetically pleasing and organized code I have seen in my 8 years of programming(I know 8 is not much, but It's at least above beginner level). The dude's a perfectionist, so I was like, "Okay, very impressive, but makes sense for perfectionism"(I straight up told him: "Damn, I've seen people with years of programming experience who can't learn to write this well, and you do this by default? I envy whoever's going to work with you"), and then I saw the way he writes checks(as in, methods that return a boolean) and I think I came.
The code was:
[First method in the picture]
And I know, it doesn't look as ✨ WOW✨ as I make it sound, but in my personal opinion this both looks much better and is much more readable than what I normally write:
[Second method in the picture]
and whenever there are longer or more complicated checks it makes it look like a simple puzzle that just fits in all the pieces nicely, for example in a rectangle class we had to write an 'isIn' method, this is how I wrote it:
[Third method in the picture]
His way of writing the same thing was:
[Fourth method in the picture]
Which I think is soooooo much better and readable and organized,
It's enough just looking at the short return statement to immediately understand everything that's going on.
"Oh, so it just checks if the SW(South West, i.e. Bottom Left) corner is above and to the right, and if the NE(North East, i.e. Top Right) corner is bellow and to the left"
Point of the story? Some people are just fucking awesome. And sometimes the youngest/most inexperienced people can teach you new tricks.
And to all of you dinosaurs here with like, 20+ years of experience, y'all can still learn even from us stupid ones. If 8 years can get schooled by a 1 month, 20 years can get schooled by a 1 year.
Listen to everyone everybody, never know where you might learn something new.
TL;DR: Got schooled by a local "Gopnik" who only started learning programming a month ago with 0 prior experience with his insane level of organization and readability.

Small feature request, but I think it would be cool if you guys could add some devducks with colored capes as well as keep the classic yellow duck as an option inside Desk Items (L).
I know its impractical to add text for obvious readability issues, but I think the base color of the actual capes would be cool, you know to match your current devduck irl :) Maybe keep the classic duck at +100 and have a higher ++ for the devducks with capes? Anyways, I'll just leave this here...
@dfox @trogus
DevDuck Cape Colors:
#222242 // Purple
#b22028 // Red
#f4f6f9 // White
#f4753e // Orange
#171615 // Black
#3a6894 // Blue

As a pretty solid Angular dev getting thrown a react project over the fence by his PM I can say:
FUCK REACT!
It is nigh impossible to write well structured, readable, well modularized code with it and not twist your mind in recursion from "lift state up" and "rendercycle downwards only"
Try writing a modular modal as a modern function component with interchangeable children (passeable to the component as it should be) that uses portals and returns the result of the passed children components.
Closest I found to it is:
c o d e s a n d b o x.io/s/7w6mq72l2q
(and its a fucking nightmare logic wise and readability wise)
And also I still wouldn't know right of the bat how to get the result from the passed child components with all the oneway binding CLUSTERFUCK.
And even if you manage to there is no chance to do it async as it should be.
You HAVE to write a lot of "HTML" tags in the DOM that practically should not be anywhere but in async functions.
In Angular this is a breeze and works like a charm.
Its not even much gray matter to it...
I can´t comprehend how companies decide to write real big web apps with it.
They must be a MESS to maintain.
For a small "four components that show a counter and fetch user images" - OK.
But fo a big webapp with a big team etc. etc.?
Asking stuff about it on Stackoverflow I got edited unsolicited as fuck and downvoted as fuck in an instant.
Nobody explained anything or even cared to look at my Stackblitz.
Unsolicited edit, downvote, closevote and of they go - no help provided whatsoever.
Its completely fine if you don't have time to help strangers - but then at least do not stomp on beginners like that.
I immediately regretted asking a toxic community like this something that I genuinely seem to not understand. Wasn't SO about helping people?
I deleted my post there and won't be coming back and doing something productive there anytime soon.
Out of respect for my clients budget I'm now doing it the ugly react way and forget about my software architecture standards but as soon as I can I will advise switching to Angular.
If you made it here: WOW
Thank you for giving me a vent to let off some steam :)13 -
So I took my old C# project "RotatingCube" for a spin and transformed the unreadable and inefficient mess into a different program, featuring better readability and more comments, with multiple cubes at once, without the shitty flickering.
I did that for school but it was quite fun to tinker with only outputting the differences to a previous output.
Check it out at https://github.com/filthycoding/...!
Next I just need multithreading for performance reasons. -
Master/Slave
Fuck you guys. Honestly most of the rants i've read concerning python and their abolishme t of sait terms where fucking butthurt. "What virgin suggested this", "people shouldn't be offended, it's just a name" and so on.
I do agree with every one saying a name shouldn't matter (readability is a different story! However parent/child or producer/consumer IMHO preserve that). So why are you fucking offended when it is changed to parent/child or produver/consumer? Does it affect you in any way? You know there's the `sed` command, plus IntelliJ (and most other IDEs) have a quite good support for renaming/refactoring stuff.
By reacting this way, by beeing offended all you do is proving the point. Words can offend people. I personally don't care how it's called. So far I always used master/slave and didn't think twice about it. But then again if someone of my coworkers or friends would feel threatened by these words, I try to avoid them. Naming diesn't matter to me, nor the compiler. So fuck, if it makes people happy or feeling save then lets change it.
What the fuck do you gain by sticking to those terms anyways?17 -
After noticing 4 operations in a single line, I comment a pr stating the line is not simple to read as there are many operations which can be, especially in the eyes of a junior, hard to read.
I proceed to suggest a better solution.
Colleague: “what??? How is this not readable??? Is it [op1], [op2], [op3] or [op4]? 🤷♂️”
I kindly explain this person that it’s not about the single operations, but the fact they are all on a line. Inside an object assignment.
Colleague: “you should learn stuff! (4 links to websites giving that snippet of code”
Ah yes, the oldie: “but other people are jumping off a cliff, why don’t WE do it???”5 -
I'm feeling like writing this down...
So today I got told off by my boss. Why? Because my job bores me.
My current title, "webmaster", is quite similar to "plumber" where I work. I fix holes on our websites, and I tell "qualified" people (external providers) how a project should be made. Nothing exciting, nothing creative, boring.
So I got told off today for being "laid-back" in a newsletter project (GDPR, looking at you) and not being thorough in my procedures of testing and configuration. Fair enough, I didn't care and I admitted it. It's a boring drag-and-drop done in literally 5 minutes, there's no added brain-value here. Plus I got told off by my IT Manager because our Exchange server would not let me receive test emails. Still doesn't work after a day. Yay.
Then she said "we're doing exciting things here, it's not always the case anywhere else you'd work". And I'm like: "really? I love writing code, seeing things coming alive, investigating why things don't run smoothly, writing efficient code (both in performance and in readability)". I hear many friend devs telling me they're doing that and what they do during their "dev-day"... All I'm doing here is "maintenance" (a.k.a boring) stuff that apparently is "exciting". Adding a <script> to handle google tag manager is hell fun, going through compiled CSS and change color values is also thrilling, finding out if a PDF handler application can handle PDF files, re-plugging a computer monitor to make it work...
I think she meant that I'm not at my place here.
Didn't want to tell her that I have no motivation in doing things I don't enjoy making, i.e, my job.
Good thing I have an interview in two weeks2 -
I keep sacrificing readability for cramming a shitload of instructions into one line. The same goes for writing comments.
-
Python is a fucking joke. "Readability" disguised as 150+ magic methods and values. Virtual environments to hide shitty dependency management. Strings that may or may not act as comments. No correlation between package and module names - install Pillow; import PIL. **kwargs instead of options=dict(), because why separate function arguments from arbitrary extra data? And finally, the only way to have tkinter on Windows is to install IDLE, so that some fucktard can stick their shitty app right up yours ...7

God I love being able to use MathJax on GitHub, despite it being quite a pain to get it perfect.
https://github.com/OpenlyEducated/...

( Still needs color though.. )
Also the bug that broke all inline mathjax for a week wasn't exactly helpful..

Man, people have the weirdest fetishes for using the most unreadable acrobatic shell garbage you have ever seen.
Some StackOverflow answers are hilarious, like the question could be something like "how do I capture regex groups and put them in a variable array?".
The answer would be some multiline command using every goddamn character possible, no indentation, no spaces to make sense of the pieces.
Regex in unix is an unholy mess. You have sed (with its modes), awk, grep (and grep -P), egrep.
I'll take js regex anytime of the day.
And everytime you need to do one simple single goddamn thing, each time it's a different broken ass syntax.
The resulting command that you end up picking is something that you'll probably forget in the next hour.
I like a good challenge, but readability is important too.
Or maybe I have very rudimentary shell skills.5 -
I want to explain to people like ostream (aka aviophille) why JS is a crap language. Because they apparently don't know (lol).
First I want to say that JS is fine for small things like gluing some parts togeter. Like, you know, the exact thing it was intended for when it was invented: scripting.
So why is it bad as a programming language for whole apps or projects?
No type checks (dynamic typing). This is typical for scripting languages and not neccesarily bad for such a language but it's certainly bad for a programming language.
"truthy" everything. It's bad for readability and it's dangerous because you can accidentaly make unwanted behavior.
The existence of == and ===. The rule for many real life JS projects is to always use === to be more safe.
In general: The correct thing should be the default thing. JS violates that.
Automatic semicolon insertion can cause funny surprises.
If semicolons aren't truly optional, then they should not be allowed to be omitted.
No enums. Do I need to say more?
No generics (of course, lol).
Fucked up implicit type conversions that violate the principle of least surprise (you know those from all the memes).
No integer data types (only floating point). BigInt obviously doesn't count.
No value types and no real concept for immutability. "Const" doesn't count because it only makes the reference immutale (see lack of value types). "Freeze" doesn't count since it's a runtime enforcement and therefore pretty useless.
No algebraic types. That one can be forgiven though, because it's only common in the most modern languages.
The need for null AND undefined.
No concept of non-nullability (values that can not be null).
JS embraces the "fail silently" approach, which means that many bugs remain unnoticed and will be a PITA to find and debug.
Some of the problems can and have been adressed with TypeScript, but most of them are unfixable because it would break backward compatibility.
So JS is truly rotten at the core and can not be fixed in principle.
That doesn't mean that I also hate JS devs. I pity your poor souls for having to deal with this abomination of a language.
It's likely that I fogot to mention many other problems with JS, so feel free to extend the list in the comments :)
Marry Christmas!34 -
to the guys saying "oop is dumb" / "i don't need oop" / "i've never worked with oop"...
i have some questions:
- which language are you working with
- which problems are you solving
- how big is your code base
- how do you maintain readability of your code?
don't get me wrong, i don't believe that oop is always the answer. i'm just curious which fields these statements are coming from. if they all come from a low level (assembler, C, ..) or functional languages or "scripty" languages (python, JS), or if there are also people working with languages like C++ where oop is pretty much established. and if the latter, i'm curious how people design their code and what problems they solve... tell me your story :D30 -
If you were to write a regular expression to match phone numbers in the format of either:
(123) 456-7890 or
123-456-7890
Would you prefer a regular expression that looked like:
A) /^(?:\(\d{3}\) |\d{3}-)\d{3}-\d{4}$/g
B) ^\(\d{3}\) \d{3}-\d{4}$|^\d{3}-\d{3}-\d{4}$/g
C) Other
D) I hate regex
Reasoning? Alternative? Discuss.
(I'm curious about preferences surrounding the readability of regular expressions)19 -
Going through some pretty fucked up shit right now : a string containing an SQL query goes though a 100+ lines function full of if{} else{} with up to 5 levels of indentation, where it replaces some parts of the query with other words... 😱1

While parsing nodes in a graph.
In terms of readability and variable naming, how wrong (if at all) is to use:
1. broNode (for sibling nodes)
2. papaNode / mamaNode (for parent nodes)
3. babyNode (for child nodes)
I sincerely don't know how to review this PR7 -

In C# using "this."
WHY? It doesn't help with readability. It just clutters up the code and adds nothing.
It should never be a required prefix.
What makes it worse is, Visual Studio greys it out because its not required!
Then there is stylecop. This got enabled on our project which generated 3000 build errors because of missing "this."9 -
Unpopular opinion.
TOML sucks
* it does not claim to care about indentation but it actually does
* nested datastructures are a nightmare, especially 'inline' for 'readability'
* oh fuck me everything must be "double quotes"
* booleans always lowercase, there is no "truthy" here.
* Tables are not intuitive at all.
And all this from working with it first time because I had the silly idea to modernize a python project to use pyproject.toml
Oh and don't get me started on pyproject.toml files. The documentation sucks!6 -
Beautiful is better than ugly.
Explicit is better than implicit.
Simple is better than complex.
Complex is better than complicated.
Flat is better than nested.
Sparse is better than dense.
Readability counts.
Special cases aren't special enough to break the rules.
Although practicality beats purity.
Errors should never pass silently.
Unless explicitly silenced.
In the face of ambiguity, refuse the temptation to guess.
There should be one-- and preferably only one --obvious way to do it.
Although that way may not be obvious at first unless you're Dutch.
Now is better than never.
Although never is often better than *right* now.
If the implementation is hard to explain, it's a bad idea.

Fuck devs for writing a fucking function in one line or 200char.
Also fuck type less one liners even more.4 -

Why enforce a 90 character limit in code file (C++)
It does not make readability any better..
you either break up functions that barely exceed the limits
or
start making nonsense variable names just because they are short.20 -
+1 if you are interested in Augmented Reality technologies, have some presentations and assignments made and you are writing your Master thesis for Augmented Reality only to find yourself working for a company that wants from you to update somehow a project with 5 years old code written from some secret antisocial society that hates readability and you as a developer and a human being and wants from you to somehow understand why they call C# method only to return a string that contains all the html tags but no data and then insert the data in JavaScript splitting the same string.
Come on, give me a break! I m still trying, though I still haven't found where exactly the program learns the data to insert or it just knows (no questions asked)...6 -
Any code should be simple and easy to read / understand.
I just reworked an old stored SQL proc.
Went from 102 lines to ... 10.
More I code, more I realize that maintainability, readability, comments and unit tests are more important than actual code. (And performances ofc. But if 1 line code does it in 1 second and 500 lines code in 0.2 seconds, I’ll take one line solution every time)5 -
i'm making my python prof wanna strangle me again, it's 100% the same as the example output, for those wondering why i do this to him it's because he said he "favors speed over readability" so i'm doing as he asks

Got asked by a coworker for some help, looked at the code and told him it could be written better and show him the example.
His reply : "It's not easy to read for me"
That was ok but then, now here's the kicker, he asked another coworker to come and see which was easier to read.
You did what mate?
So of course i got pissed and went out for a smoke just to return to see my version being used.
WHY THE FUCK DID YOU ARGUE ABOUT READABILITY IF YOU"RE GOING TO USE IT ANYWAY???

How the fuck are Jupyter notebooks so popular in research? Like some dude had an idea to take perfectly good markdown and python code, add a whole lot of transitional properties to make version control impossible, encode it as JSON on the assumption that a human could somehow look at it and make sense of countless escaped characters and base64 encoded data, create dedicated software people need to install in order to read what used to be simple plain text, and think "This. This is what 99% of data researchers will use from now on." And somehow, overwhelming majority of researchers agreed that this extremely inefficient data format is the best there is and they should develop all their tools around it.11 -
Fuck accessibility.
No WAIT, before you call me an asshole hear me out.
So when you use CSS grid to create layouts you're supposed to not use the features it has (reordering items) too much, and instead keep the HTML structured the way it's supposed to be read.
When you add a picture of a cat you're supposed to put a alt="Brown cat sitting on a chair" there.
Also you should test for all kinds of sight disabilities and use high contrast colors.
All that for likely <1% of your users.
What would be the alternative? HTML is a markup language, and not supposed to be directly read by humans. Invest the time ONCE for screenreaders to understand CSS positioning and read content in a sensible order. Use image recognition to describe pictures (with selectable levels of detail). Let the browser modify colors on the fly for better readability.
Don't spend time and money to solve a problem 100000 Times that could be solved once.
Fuck accessibility.28 -
Inherited a codebase that implements its own word wrapping for receipt printing. Problem is it's putting an extra space at the end of each line.
I open up the implementation, expecting it to be a relatively simple fix, until I see this…

Question PHP folks. Is it a standard to write:
public function hair()?
Writing only:
function hair() is just the same thing to the above. It will default to "public" hair right? 🤔 maybe just a PSR-2 standard or for readability? Thanks!3 -
If I could, I'd attempt to create an ideal language. I'd aspire that its features would be:
-The easyiness of Python
-The library ecosystem of Javascript
-The readability and cross- platformness of Java
-Functional features of Haskell
-Modularity of Lisp
-Low level features of C/C++
-Powerful with strings and data, like Perl
-Both compiled and interpreted, with REPL
Anything missing from your favorite languages?9 -

A coworker wants to save telphone numbers as Strings in a database I don't get why he doesn't want to use Ints. I think it is stupid because it uses more space and you need to change the type if you want to use it to call someone.

I'm shitting there hammering out some code butchering some real problems when I suddenly realise I'm surrounded. I look around and yes it's the bloody committee.
The committee is what I call the rest of the department and it is dominated by the old guard which comprises of the programmers that have been around for longer.
None of the old guard can program particularly well but because they had been around the longest they'd all grown senior. The committee had free reign but anyone else doing anything differently has to get approval from the committee.
The only way to code otherwise was to copy and paste existing code then to primarily rename things. If anyone did anything that hadn't been seen before then it would have to be approved by the committee. Individual action was not permitted unless you were old guard.
I swept my headphones away expecting it to be something unimportant. It was.
First things first they announce. We're going to add extraneous commas to the last element of all possible lists separated by comma including parameters or so they say. Ask but why so I do.
Because the language now supports it. They added support for it so it must be the right way someone proclaimed. Does it? I didn't realise we were waiting for it. Why do we want it though?
Didn't you hear? It's all over the blogosphere. It massively improves merge requests. But how I ask?
Five minutes later I grow tired of the chin stroking, elbow harnessing, slanted gazes into the yonder and occasionally hearing maybe its because and ask if they mean when you for example add an element the last element registers as changed from adding a comma. Turns out that's all it is.
How often do we see that tiny distraction and isn't it pointless to make the code ugly just for a tiny transient reduction in diff noise I ask. Everyone's stumped. This went on and on and got worse and worse. But it makes moving things around easy half of them say in unison like the bunch of slobs that they are. I mean really. It doesn't make expanding and contracting statements from multiline to single line easy and it's such a stupid thing. Is that all they do all day? Move multi-line method parameters up and down all day? If their coding conventions weren't totally whack they wouldn't have so many multiline method prototypes with stupid amounts of parameters with stupidly long types and names. They all use the same smart IDE which can also surely handle fixing the last comma and why is that even a concern given all the other outrageously verbose and excessive conventions for readability?
But you know what, who cares, fine, whatever. Lets put commas all over the shop and then we can all go to the pub and woo the ladies with how cool and trendy we are up to date with all the latest trends and fashions then we go home with ten babes hanging off each arm and get so laid we have to take a sick day the following to go to the STD clinic. Make way for we are conformists.
But then someone had to do it. They had to bring up PSR. Yes, another braindead committee that produces stupid decisions. Should brackets be same line or next line, I know, lets do both they decided. Now we have to do PSR and aren't allowed to use sensible conventions.
But why, I ask after explaining it's actually quite useful as a set of documents we can plagiarise as a starting point but then modify but no, we have to do exactly what PSR says. We're all too stupid apparently you see. Apparently we're not on their level. We're mere mortals. The reason or so I'm told, is so that anyone can come in and is they know PSR coding styles be able to read and write the code. That's not how it works. If you can't adjust to a different style, a more consistent style, that's not massively bizarre or atypical but rather with only minor differences from standard styles, you're useless. That's not even an argument, it's a confession that you've got a lump of coal where your brain's supposed to be.
Through all of this I don't really care because I long ago just made my own code generators or transpilers that work two ways and switch things between my shit and their shit but share my wisdom anyway because I'm a greedy scumbag like that.
Where the shit really hit the fan is that I pointed out that PSR style guide doesn't answer all questions nor covers all cases so what do we do then. If it's not in PSR? Then we're fucked.4 -

the Death Valley of PR approval
I have almost 3 years of work experience in programming professionally. Currently this is my second company. Previous company I worked for was very loose regarding clean code, code readability, tests etc. It was their way of doing things fast, making working changes quickly was the most important thing due to its business. Now I work in company where I spend a lot of time in some limbo when my code works and my code is merged. It sucks, I make all kinds of mistakes which would be tolerable in my previous workplace, but now it keeps me from releasing code. I now the way I do things now is the right way and it will result in me growing as a specialist, but it is very frustrating and damages my self esteem. I hope it will pass one day.7 -
How do I become good with functional features(map,reduce,filter,zip,flatmap) in Javascript and Python?
It feels so alien. I'm so used to writing plain old loops.

A fellow PHP dev I know implies procedural php is better in any way shape or form than OOP as it increases readability...3

So I made a pull request on a PHP public repo fixing line lengths and adding some spacing for readability. All in the hopes of improving it to follow PSR-2 standards which they specifically say they follow.
Pull request got rejected, reason: "No thanks, the code is good enough."

Me on code review : You should extract the logic into a separate method for better readability. Colleague completely ignores it. What should I do?6

Someone just explain me why. I really can't figure other reason that beeing too lazy to think a condition while writing a "while loop".
At university, a colleague asked me what i think of his code. I see something like that:
while ( 1 ){

if (condition)
break;
...
}
Am I a fucking genius thinking that just moving condition into while will improve readability, or am i a fucking stupid ? Really not the first time seeing this, maybe i am missing something.4 -

!rant but a question...
I know that with the vast examples/tutorials online this may not be necessary, but I wanted to ask the community if you guys/gals would recommend going back to school to get a formal CS education or if it would be a waste of time, money, and resources compared to just using web based sources? I've tried the college thing 3 times when I was younger but couldn't concentrate and lacked the discipline to focus and finish classes. But I'm a bit older now and wanted to know if you would recommend going back to school or if time would be better spent performing self-study and learning from home?
I'm still extremely new to coding and programming and only have basic knowledge of actual coding and a lot of the theoretical stuff in programming is completely foreign to me. Like for example, how to optimize code. I know that refactoring code to have a smaller more efficient footprint is always desirable, when it doesn't interfere with readability, but I'm unaware of where/how to modify code to run efficiently. Of course that may be wayyy to advanced for my use cases anyway 😂.
I'm trying to teach myself python as it seems like a great language for starting out and getting to understand the concepts of programing. Plus, it can be used directly in my line of work as well as side projects that I wanted to try my hand at.
Thank you in advance for your recommendations everyone!2 -
So i bribed a fellow dev/friend who HATES php and Magento... to help me grind out a Magento site while im super behind on a bunch of crap that's mostly boring administrative bs (#ReluctantlyInCharge)
He knew I was coding in python several times over the past several months... yet, despite my near constant griping of formatting bs and high preference of basically anything that doesnt require readability-esq formatting... he apparently didnt get it.
I need to make a quick splash page with a timer on it (other cool elements that i dont think ive ever seen done but i figured why not... weird shit is totally on brand here... like scripting page elements to change and see if people catch on... in very basic ways)...
I know js plenty... but I'd likely have looked up the syntax, was lazy, he loves js (for the intended purpose... he does a lot of blockchain dev) so i asked if hed write me a quick timer line cuz... well im lazy.
He totally overcomplicated it and sends me a page he typed up incl html header. Timer was 3 short block/lines with semicolons... i laughed and wondered why he did all that instead of just the little js... he didnt know either. I told him as a courtesy id make sure to keep the js formatting as he wrote it instead of 1 line...
He sends me 2 examples of a js timer in 1 line... like 1semicolon... i had to show him what i actually meant... 3 'lines' with semicolons on 1 visual line...
He was stunned, then realised i must really hate python11 -

Management suddenly decides they wanted to see if a new process is any good and decides to load all the work on 2 people ( including me ) and keeps the deadline 5 days later ( when one person is taking a 3 day leave in this 5 days ).
In this situation, the other person involved in the process, routinely infuriates me by suggesting we fix up something within these days and not worry about readability or code quality. My argument is the POC is subject to heavy changes, so why not make it more "modifiable" from the start and not create a sphagetti which i would be left trying to fix when he goes on leave.
I would be blamed for slowing down things unnecessarily if i put forward my argument too sternly. Genuinely conflicted about whether to go on the offensive or to accept the reality and make myself uncomfortable by doing this faster.2 -

If only more devs would use short, yet concise, modern constructs instead of archaic ones.
For example in C#: using lambdas, extension methods, LinQ,.. much easier to read through if you know how these work, rather than having to spend all day scanning tedious for-loops and over-engineered classes your colleagues wrote who don't know any better.
Examples:
vs.foreach(v => console.write(v));
initialList = secondList.Where(p => initialList.Contains(p, valueComparer))
.Concat(initialList.Where(p => !secondList.Contains(p, valueComparer))).ToList(); -
It is better to write almost all of the logic used in the code as comments/documentation.
Trust me.
It is a good thing. It increases Code readability.
Nobody is going to copy your logic and get hired in a high paying job or get promoted for that reason. People will come to know about your wit and will appreciate you instead.2 -
I have so much to rant right now. So much. Life is pretty much a tight rope walk right now.
But the project I'm working on right now is annoying. I've ten days to release. It's a website on WordPress. They want complex animated crap using GSAP that fucks readability in the ass. I don't even know how to do animations. I don't JS damn it. Apparently readability is not what we want. We want attention grabbing. It's a fucking government initiative website for crying out loud. Why not put a carousel with my curated list of porn then? They also want the pages to be build using blocks of modules on a page builder so that the client can produce new pages without our help. I still don't have the final designs even. When I asked for the mobile designs, they told me to "just make it look not broken". Uggh.
They spent three weeks making some shit on Squarespace and now they expect me to finish the entire fucking thing with the slutty animations, disgusting text sizes and fucked up designs sense and symmetry in pretty much a week.

Sydochen has posted a rant where he is nt really sure why people hate Java, and I decided to publicly post my explanation of this phenomenon, please, from my point of view.
So there is this quite large domain, on which one or two academical studies are built, such as business informatics and applied system engineering which I find extremely interesting and fun, that is called, ironically, SAD. And then there are videos on youtube, by programmers who just can't settle the fuck down. Those videos I am talking about are rants about OOP in general, which, as we all know, is a huge part of studies in the aforementioned domain. What these people are even talking about?
Absolutely obvious, there is no sense in making a software in a linear pattern. Since Bikelsoft has conveniently patched consumers up with GUI based software, the core concept of which is EDP (event driven programming or alternatively, at least OS events queue-ing), the completely functional, linear approach in such environment does not make much sense in terms of the maintainability of the software. Uhm, raise your hand if you ever tried to linearly build a complex GUI system in a single function call on GTK, which does allow you to disregard any responsibility separation pattern of SAD, such as long loved MVC...
Additionally, OOP is mandatory in business because it does allow us to mount abstraction levels and encapsulate actual dataflow behind them, which, of course, lowers the costs of the development.
What happy programmers are talking about usually is the complexity of the task of doing the OOP right in the sense of an overflow of straight composition classes (that do nothing but forward data from lower to upper abstraction levels and vice versa) and the situation of responsibility chain break (this is when a class from lower level directly!! notifies a class of a higher level about something ignoring the fact that there is a chain of other classes between them). And that's it. These guys also do vouch for functional programming, and it's a completely different argument, and there is no reason not to do it in algorithmical, implementational part of the project, of course, but yeah...
So where does Java kick in you think?
Well, guess what language popularized programming in general and OOP in particular. Java is doing a lot of things in a modern way. Of course, if it's 1995 outside *lenny face*. Yeah, fuck AOT, fuck memory management responsibility, all to the maximum towards solving the real applicative tasks.
Have you ever tried to learn to apply Text Watchers in Android with Java? Then you know about inline overloading and inline abstract class implementation. This is not right. This reduces readability and reusability.
Have you ever used Volley on Android? Newbies to Android programming surely should have. Quite verbose boilerplate in google docs, huh?
Have you seen intents? The Android API is, little said, messy with all the support libs and Context class ancestors. Remember how many times the language has helped you to properly orient in all of this hierarchy, when overloading method declaration requires you to use 2 lines instead of 1. Too verbose, too hesitant, distracting - that's what the lang and the api is. Fucking toString() is hilarious. Reference comparison is unintuitive. Obviously poor practices are not banned. Ancient tools. Import hell. Slow evolution.
C# has ripped Java off like an utter cunt, yet it's a piece of cake to maintain a solid patternization and structure, and keep your code clean and readable. Yet, Cs6 already was okay featuring optionally nullable fields and safe optional dereferencing, while we get finally get lambda expressions in J8, in 20-fucking-14.
Java did good back then, but when we joke about dumb indian developers, they are coding it in Java. So yeah.
To sum up, it's easy to make code unreadable with Java, and Java is a tool with which developers usually disregard the patterns of SAD. -

Please for the love of god, follow some rules! My first language was python, i love its zen:
- Beautiful is better than ugly.
- Simple is better than complex.
- Readability counts.
- Special cases aren't special enough to break the rules.
- There should be one-- and preferably only one --obvious way to do it.
- If the implementation is hard to explain, it's a bad idea.

you either get unreadable rust code or 7 layers of misdirection so that the compiler can work around keeping track of lifetimes
I mean maybe I'm too opinionated about readability. technically the computer can read it so people should just get good I guess -
tell me guys what would you prefer:
function a(){
..
b(..)
..
b(..)
..
}
function b(p1,p2,p3,p4,p5,p6){.

}
or
function a(){
..
b(..)
..
b(..)
..
}
function b(
p1,
p2,
p3,
p4,
p5,
p6
){
...
}
if you read this rant before expanding, you got a complete context on how what function a is, its calling b 2 times and how function b looks.
if instead of the first option, i had used 2nd block, you wouldn't even know the 2nd param of b function without expanding this rant.
my point?
i prefer to keeping unnecessary info on one line. and w lot of linters disagree by splitting up the code. and most importantly , my arrogant tl disagree by saying he prefers the splitted code "for readability" and becaue "he likes code this way, old-eng1 likes this and old-eng2 likes this" .
why tf does an ide have horizontal a scrolling option available when you are too stupid to use it?
ok, i know some smartass is going to point that i too can use vertical scrolling, but hear me out: i am optimising this!

- since all params could have similar charactersticks ( they will be of some type, might have defaults, might be a suspendable/async function etc), each param will take similar memory-efforts points. say 5sp each.
- total memory-efforts= 5sp *7 = 35 sp.
- say a human has 100 sp of fast memory storage, he can use the remaining 65 sp for loading say 5 small lines above or below.
- but since 5 lines above are already read and still visible on screen, they won't be needed to be loaded again nd again, nd we can just check the lines below.
- thus we are able to store 65+35+65 = 165 sp or about 11 lines of code in out fast memory for just a 100sp brain storage
case 2 function with 7 params IS split into 7 lines.
- in this case all lines are somewhat similar. 5sp for param lines as they are still similar which implies same 35sp for storing current function and params
- remaining 65sp can only be used to store next 5 lines of 13sp as the previous code is no longer visible.
- plus if you wanna refresh the code above, you gotta scroll, which will result in removing bottom code from screen , and now your 65sp from bottom code is overwritten by 65sp of top code.
- thus at a time, you are storing only 6 lines worth of code info. this makes you slow.
this is some imaginary math, but i believe it works10 -
Some 80s and 90s books. And the more the time goes by the more I lean towards FP and stateless systems...
On the syntactic side I love the work of Kevlin Henney. For me it's all about readability. So a lot of choices are based on that. -
OpenSource is fun they said. I being a bored teen thought, ah, another chance to experiment. Discover something new. Now I am into piracy, movies, music, software. If I can get it for free I ain't paying for it. So I went on to GitHub to see what exciting new Repos I could contribute to. I hate already implemented plenty of algorithms in GO for GitHub.com/TheAlgorithms so I was looking something more practical, more beneficial to society. Then I saw it, the perfect repo, not too complex and not amateur. SpotDL/spotify-downloader for downloading songs from Spotify, a grey area coz it's technically piracy. Well not from Spotify, we fetch the info from the Spotify API and search for the songs on YouTubeMusic. They were just about to release v3, a complete rewrite of the codebase stressing code readability and stuff. I spend about a day studying the codebase, trying to findout just where I could make my contribution. I can see outright that there's a huge problem with implementation.
First of all the script spawns 4 processes for downloading songs though you might be downloading only one song. Which means for everytime you run the script you have to wait for 4 other processes to be spawned before any downloading can happen. Sure this is faster when you are downloading more than like 4 songs, but it's actually slower when downloading a single song. But I ignored that coz I assumed that most users download playlists and albums. Anyway we talked with the like lead developer and he was all like, make those PRs anytime you feel like. So I made a really minor first contribution.
I introduced download from Spotify URI functionality, modified like 10 lines of code. I was half expecting that the PR would be merged within hours at most 24 hours coz of how minor of a contribution it was, 5 days in it was pending. So I tagged the lead Dev and he was all appreciative of the PR, calling it real 'clean code' and stuff. 3 more days, the PR is still not merged. I have now stacked 4 more commits to the same PR, I tag the dev and he's like he's waiting to see if my 'feature' will get atleast 10 upvotes so that it can be merged, he links an issue. I go to the issue and my feature is not there, So 11 days after I made my PR I have to write a comment explaining the 'feature' introduced in my PR and then wait for 10 upvotes.
I was like f**k this, I'll just develop on my fork if you want the features on my fork, you will make your own PR! I am so done with OpenSource, development is slow. I have no idea how you guys do it. I can't handle development where I don't have write access.6 -
I'm working in a project that seems to be like a Multiplayer Tetris of Little Poo:
- figure out what the heck you have to code, because there is no debugging, the deploy to your devenv takes ages, the documentation does not exist or is unreadable, plus you are new and you are in a different timezone
- once you have your code, slowly pass the reviews of your remote team that will complain for every little extra line you've added for readability, slowly converting your code into a poo-like form, until it is completely shaped as shit
- repeat steps 1-2 until you pass the linter
- the carefully place your shit-shaped-code in the right place of the pile of shit
- wait for someone else to complain (like 'please rebase' 'new lint rule please fix' - oh, did I mention that? lint rules do not match between local, review and deploy?
- repeat from step 1 until you quit your job (which will happen in a few weeks) -
what's the best practice to divide long task into functions? suppose I have function of 200+ lines then from the code readability point doing short functions would be better?3

My coding style is mostly influenced by good old personal preference, but also because of a certain internship where there was a lot of gain to be had by making everything as reusable and testable as possible.
I guess you could say my motto is usability, readability and flexibility:
I like tidy, reusable code with an emphasis on keeping code readable. I've always liked modular things I guess...
And I despise two things: curly brackets on the next line and spaces for indentation... But way worse is having no brackets at all (looking at you Python): it's clearer to have lower-level code inside some sort of "container" markers i.e. brackets (also gives more IDE functionality like color-coding hierarchically).
Indentation should always be tabs so anyone can have their own width of indentation set through their IDE, making it way more accessible to fellow colleagues!
And I also like having parameterized code over hard-coded functions: way more flexible. -
Is this a justified code review comment or a bully?
Code reviews are weakness of this industry which has the potential to attract bullies. Abuse of the comment box in a pull request and bombarding the employee with hundreds of comments can cause stress, frustration, burnout and finally resignation and costs of fulfillment for the organization. While companies should find and stop bullying in the work place, what kind of code review comment is considered a bully and why? Any of below traits can mean you are dealing with a bully:
1. Claims the code needs to be changed but doesn't say how. So no matter how many times you change your code, he can repeat the same comment: "Your code is still bad due to blah blah and it needs to be changed".
2. Provides how the code should be changed, but the change doesn't add up to quality, security, performance, readability, etc. i.e. "Why did you use a for loop here? Use a while loop instead". Or "Why did you write it using three classes A, B and C? Instead write it using 4 classes D, E, F and G which does blah blah". In the later case, not following the review comment, you won't get approval. Following the comment means you need to rewrite your whole code. After which, you might again receive more comments to change other parts of your code!
3. Claims the requested change is due to standards but claimed standard does exist anywhere. Internet, company wiki, university course books, anywhere. In more severe cases of psychopathy, the bullying person refers you to a link which hours later turned out to be written by himself! Have fun describing what has happened to your manager or team leader... .
4. Asks the code to be changed in a way that supposedly is closer to standard or of better quality, security, performance, etc. But the proposed way will not work and is the main reason you didn't do that in the first place. So you start arguing forever in the comment box over why his method won't work!
If you cannot see any of the above traits, then keep calm, take a breath, fix your code. Otherwise you might be victim of a bully.3 -

Looking for help starting with DevOps.
Does anyone know of a site or forum where you can talk about general coding/scripting patterns rather than just asking specific questions?
Bear with me, this may be a bit longer than most posts here.
I'm a self-taught admin/tech working with one colleague (who's also mostly self taught) at a high school, managing both clients and servers.
We've been doing most things manually bit I'm looking into converting as much work as possible into more of a DevOps setup, with Powershell-scripts for multi step tasks.
I want to do this for a number of reasons. Having a script doing a number of steps would cut down on time spent on individual tasks and minimize the risk that a step is missed or, perhaps even worse, mistyped. Also it's important that I actually learn what I'm doing, why something works and why something fails.
As and example, I have a powershell-script which moves a student from one year to another (basically they have user names with a two-digit prefix based on the year they started and a suffix with two letters from their first names and four from their last names) if they need to repeat a grade.
It basically renames the account in the AD with the correct year-prefix, changes the samAccountName, renames Home and Profile-directories on disk and changes paths on the profile-tab in AD, moves the user into a new OU and security group etc.
It works as intended if the user account to be renamed exists and there's no name conflict with the new name. But I'd like for the script to validate that there's no problem with user names, source and target security groups and OUs etc. and eventually split the script up into smaller clearly defined functions for better readability.
However, I don't want someone to just write the script for me, I'd prefer to be able to discuss script flow and come to my own conclusions and solutions.1 -
Was generating a JSON based config manually to be used by a script another dev wrote - only to be criticized for using the text editors built in formatter. Evidently lining up the colon separating key value pairs is a thing.
If readability was so important to you why the fuck did you decide on using JSON as a configuration format? Especially when you could have gone with YAML or better yet INI (flat key/value pairs) style config. -
i thought whiteboarding turning into leetcode mediums or harder correctly in 20 minutes or less was bad
now codesignal is fucking us over, tried my first one without researching any of the code score shit
anybody have tips for gaming the system there? i heard claims that speed trumps correctness for their point system (e.g. faster but not passing for all test cases may score higher than slower but all test cases pass) additionally code cleanliness/readability isn't weighed as heavily as the other factors
and to do problems individually to completion further rather than spreading yourself out across multiple problems in an exam
wont deny im still a salty scrub at the end of the day
