Just noticed on "winehq" that the acronym for "Wine" is "Wine Is Not an Emulator". This is great and all, but all my mind can think about is the infinite recursion problem they've got there.11

Hey girl,
I want our relationship to be a poor recursion, so that it never terminates.

Is it just me or does this shirt make no sense? If your coffee was empty, then it would return true and you would keep coding. If it was not empty you would fill it.
Plus it's not a while loop, so unless this is some sort of recursion you wouldn't keep going....

When I was in 8th grade and was learning to code (c++), I sincerely believed that calling a function within a function simply calls it again (like in a loop) . I had never heard of recursion.
And I actually made a small project in which I called a function again and again thinking that calling another terminates the previous one.
No wonder my program kept crashing. I have still kept that code with me as a wonderful memory.
I know this isn't particularly interesting, but I just saw that code today and felt like sharing this...3 -

Me: *spends 5 hours screwing around with recursion and performing operations in reverse order*
Unit tests: *pass*
Me: Wow. Okay, that’s interesting.
*run tests again*
Me: Right, well, that’s just dandy. Now, how did I get here and how do I document this...
TL;DR I spent 5 hours fucking about and accidentally came up with a working solution that I can’t explain
EDIT: RIP wrong category1 -
So I've got a recursive function that calls a recursive function that has a nested recursive function inside it.

At a restaurant in Augustow there was a sign: "please wait for the waiter"
it confused me. If I'm waiting for the waiter, then what/who's the waiter: the one who's being waited for or the one waiting?
If I'm waiting for the waiter, do I become the waiter?
I think this is a good spot for a recursion bug to occur, resulting in waiter leaks.4 -
I used to prefer, think, and code in loops rather recursion.
Now though somehow it's the other way around...
And I have to assure myself why a piece of code I wrote won't cause a Stack overflow... and that if I really had to I could convert it back to a loop.
Haven't done it though for a awhile tho...7 -
Top 3 times:
1) When I amazed myself by solving a problem using recursion.
2) When I taught myself how to make my a restful api and consumed it using Ajax.
3) When I converted a psd in to a responsive pixel perfect webpage.

Yesterday was the first time i used recursion to solve an issue in our project..Never felt so good 😁6

I remember when I was first learning recursion, i thought whoever thought of it must've been on some kickass drugs because it all sounded like sorcery. Just solved my first problem at work that recursion actually made simpler. Does that make me a wizard?10

I just came across this piece of recursive code, as much as I can guess this should be an infinite recursion but somehow it executes and does terminate. Can anybody tell me how this happens and what will be it's time complexity ?

Haven't used it since and hopefully never will again, but understanding recursion and keyboard input in Assembly (uni project)
After a long (4 days) sleepover with my friends, with 14 hours a day of slamming our heads against abstract registers, we could finally program the factorial and take floating numbers as input and output them on the screen. It was nothing but pain, but the moment we got it, the sky had opened before us :D

Another rant reminded me of one of my dad’s favorite sayings about experience...
Some people have ten years of experience. Others have one year of experience repeated ten times.
..and for ohers, the recursion interval is shorter still...
As a bonus, here’s another personal favorite: “Nobody’s completely useless. They can always be used as a bad example.”1 -
That feeling when recursion finally "clicks", and you begin instantly identifying candidates in your code for recursive solutions.20

I just wrote a function with a while loop AND recursion because I wasn't paying attention.
That was fun. Also, MySQL isn't happy right now. I'm posting while I'm waiting for my local service to restart.3 -

Programming contest assignments, first level:
1. "...if you don't know how to return values from a function, you can just print them"
2. "...if you don't know how to read files, you can assume data is in global variables"
3. Required recursion
4. "...and estimate its time complexity.", "You may pre-process the data, but use at most o(n^3)", "your algorithm must use under n^3 operations"
That escalated quickly!1 -

Meetings.
Too many meetings.
"Why do you explain...." 10kv electrical shock.
Explanation so everyone has the same knowledge.
"But CD ES process of LCE..." Water. From the emergency hose. In the face.
For fucks sake, we are using speech in a meeting so stop using motherfucking abbreviations you shit hole.
"We had bugs". Taking an hot iron and shoving it somewhere nice.
Explain - what the fuck are you talking about? What bugs? Tickets? Documentation? Implications of the bugs? Hate. Much hate.
Um. I don't know. Maybe. But if.
Thumb wrenches.
Please, stop wasting time, if it's non important, a " No " doesn't hurt....
Let me show you. (4k Monitor, 10 px font, bright neon colors, IDE looks like LSD trip in bad).
Crucification.
If you present stuff, good - but for christs sake, shove your motherfucking shitty IDE setting in your own arse and turn on presentation mode with neutral colors - bright or dark mode, I don't care, but readable without danger of seizure.
I can't stream my monitor right now because of "bla" "blabla" (some private shit that has ZERO to do with work).
I'll need some oxy if this goes on.2 -
I don't really get why the word inception is used as a synonym for recursion.
Inception is about injecting a tought in someone else's mind.

Recursion-mode ON16 -
had an incredibly productive day today on the ultradark blockchain. wrote a bunch of tests, updated documentation, split the repo into 3 seperate ones because it got too big and had too many different things in it, AND accidentally fixed an annoying, deep-recursion bug that ive noticed for a while now.
seems too good to be true...1 -
wow, I have to say, tail recursion, slices, iterator transformers and shadowing are great building blocks for parsers. I'm actually way faster at defining and modifying procedural parsers with Rust's tools than I am with Chumsky. I actually understand which of my checks are greedy and lazy now!
-
So I have this code written in node:
Function connect(){
const client = net.blahblah
client.on('close', () => {
Connect()
}
}
As the connect is called from within the close call back, it wouldn't be recursive right? Like if it disconnected a million times, it shouldn't throw a recursion error or use up a bunch of memory right? Or am I thinking about it wrong?2 -
Possibly my favourite function is Clojure's "recur", which isn't really a function at all, but a special form that gives you a guaranteed tail-position call to the current function.
Basically what that means is you can write recursive functions (functions that call themselves) and know that you're not creating a potential stack overflow.
Um. Okay, I can feel people looking at me like 🤔 Basically what *that* means is: normally when a function calls another function, a "stack frame" is allocated, holding all the local variables for that call. If a function calls itself 1000 times, 1000 stack frames get allocated. "Tail call optimisation" is a process by which if you call yourself as the very last thing in a function, the language doesn't need to remember the current frame; it just has to pass the return value upwards. The trouble is, it's sometimes hard to notice that you've turned a tail-call optimisable function into a non-optimisable one. Clojure's recur keyword makes it explicit, and therefore safe: if you try to do anything with the return value of recur, it's an error.
PS I'm sure another language did explicit TCR first, but Clojure is where I first saw it.6 -
Scheduled an on-site. *internal screaming*
Does anyone have any resources for studying distributed computing and operating system topics or have any pointers for studying for a systems design interview?
Also, how did y’all get comfortable with recursion? I don’t have issues with problems I already know the solutions to but it’s like when that’s not the case my brain just goes into panic mode for a bit.
Teach me your ways?7 -

Couldn't find any satisfactory explanation online, so here is a question. Discussions idea etc are welcome.
How is the colour fill tool implemented in paint or other software?
I remember it running superfast on old 98 machines. Got me curious to think how they achieved it.
(correct me if I am wrong, recursion won't be a good idea for large images.)4 -
*me to myself* okay this time I'm not solving that problem with recursion. The assignment is hard enough already.
*A ton of sweat, blood and hours later* Whoops. -
does recursion have any practical use outside of being a cute/elegant solution under constraints where stack overflow isn't a concern due to small input size, and leetcode?
im having trouble thinking of anywhere you could justify using recursion in industry outside of leetcoding people
i assume the iterative approach would be preferred in scenarios where scaling matters18 -
It is Saturday 19:30 and I am spending my time writing functions for save/load data in a binary tree. Recursion and fscanf are not a good combo so far, but that is the task. When the code is done I have to get some math done.

Spending days on a recursion problem and never solving it. That was a low time for me-especially when I looked at how short and elegant the solution was online. I've recovered now and have gotten better at it, but damn that's one thing I need master or it'll haunt me to I die.1

OCD driven development
- level of recursion determined by how much the algorithm bothers you
- too much and nothing is ever finished
- not enough and code is shitty and unmaintainable
- can result is longer variable names
- takes longer to name a variable
- text slightly misaligned requires hours of debugging time
- balanced by "OMFG that will take forever to fix" Sometimes...
- can lead to unobjective code reviews1 -

what do you think about the idea of... "pseudo-recursion"?
as in, language construct that looks basically like recursion except one detail that makes it translate into iterative execution where the "recursion" calls just add to the list of "execute in next layer" ...iterator-type variable(?)
also, if you understand what I mean and if it's not complete nonsense, any syntax suggestions that would seem most natural for you? (also for context tell me what language that syntax suggestion mostly draws from (and why))

Ok so.. thoughts on MySQL,
SELECT max(column_name) from table_name;
Outputs the max value in the column by kinda traversing the whole column huh... Recursive🤔
While
SELECT concat(column_name) from table_name; outputs simple endl separated srrings. . .. no recursion. PHP backend sucks

I got to a point where I have a multi-level recursive promises within loops and my mental map is by far not enough to process this. I wish there were some visualisation tools for this - though I don't even know how it could look like. All I know is that at some point I'm returning a wrong promise and the recursion is not correctly handled.7
