Client : Can you make some adblock?
Me : Why? There is a lot of good things already...
C : I mean... Listen carefully.
M : ok
C: i have some google ads and user blocks with adblock
M : yeah, that is normal
C : so i implemented adblock blocker which blocks adblock so that i can show the webpage plus ads when the user disables adblock.
M : i bet users hate that.
C : yeah, so users found out a way to disable adblock blocker which disables adblock blocker which i implemented to show the ads! So i cant earn revenue..
M : so what?
C : Can you make ad block block block block?
M : Sure. How much will you give me ?
C : 20 to 30 dollars
M : great ( the most generous client ever seen)
*couple of years later*
Client : can you make ad block block block block block block block block block block?
Me : i cant understand
C : count the number of block
If there is odd number of block i means to block ads.
If there is even number of block ads, it means to show ads making user to disable ads.
M : so just tldr your request this time
C : even number
M : ok how much will you pay
C : 20 to 30 dollars
*next day*
C : can you..
M : offline
Who in the fucking world made ads, made adblock and made adblock block?17 -

New Guy Day 2: He has deleted the git repo on the project he was assigned to 4 times, written a recursion formula that crashed a server, & knocked my coffee cup onto the floor.
I messaged my boss telling him I am going to hide the body in his trunk.8 -
My programming teacher is a freaking degenerate. He spend 7 months teaching us basic stuff like if-clauses, while-loops and stuff like that over and over again - everyone was annoyed but he didn't listen to us because "some people still don't get it". (The reason for this could be their total absence during lessons but who am I to tell.)
Beginning of 2018 he realised we hadn't much time left to prepare for our final exam so he tried self-taught learning. 8 sorting algorithms, recursion, how to write classes and objects in less than a week. And of course there was a classtest about this - needless to say that like nobody passed it. He still has no clue why we are "so lazy and dumb".
One of his favourite code examples is a calculator. I don't know how many i've programmed and they've gotten more and more ridiculous. (Who the hell would want interfaces like IComparer in a calculator?)
He even wanted to convince us that for-loops can't count down (and that things like "i--" doen't exist.)
I could go on and on about this guy and his craziness.27 -

Navy story time again.
I was a cadet, 1st year, final exams in """CS""". Our """professor""" was handing out the exam sheets, when I told him that one of the questions couldn't be answered by what he had taught. He had supposedly taught us C++ (I would insult every C++ tutorial, however shitty, if I called his class introductory or even elemental).
To give you a better idea of the situation, I'll only say this: one of the questions was "Name three brands of antivirus software."
I. SHIT. YOU. NOT.
This was supposed to be a Naval Academy that trained officers, by the way. Anyway, the question at hand was a program that must use recursion to solve a particular problem. I had been studying programming since high school, so I was not bothered by it, but everyone else was. Anyway...
Once I told him that, he threw a fucking fit. He screamed (as our overseeing officer watched in confusion) that we weren't paying attention, that we were just playing around and watching porn sites (BTW I discovered after that, that most porn videos were on the campus server, in write-protected folders that no student had permission to write, but professors and administrators did. Curious... but my ITSec misdeeds are for another day). Anyway, I got so angry at that idiot, I started writing (yes, programming on paper, if you whine about your IDE/text editor, think about that) the program. Until I found out that I didn't know WTF I was writing. The time was up, however, and I had to give my paper. To this day I have no idea what I wrote and what it did (if anything).
Got perfect score. Only one in class.9 -
Aaaah...I just got back from a meeting because of a production data problem caused by an analyst who keeps making mistakes that screw up client data. I wrote a program to automate most of it and everybody initially accused me of having a buggy program, only to find out she wasn't using it, never did.
"Why aren't you using the program then?" was asked. "Oh, well, I just understand my way better," she replies, "When I make a mistake at least I understand why."
Pause....
"Then, um, if you know you're making a mistake, why don't you fix it?"
"Because my process is so manual and labor intensive sometimes it's not worth it to go back and fix it, because I'd have to do everything over again, and you guys are much better at fixing this stuff than I am."
I indicated that everyone is too busy to stop and fix her mistakes, to which she then asks:
"So if you can't fix my mistakes, what am I supposed to do?"7 -

The exact moment when I understood what programming actually was.
I was getting hard times at my 3rd college grade, trying to implement the recursive sudoku solver in python. Teacher spent a lot of time trying to explain me things like referential transparency, recursion and returning the new value instead of modifying the old one and everything related. I just couldn't get it.
I was one of the least productive students, i couldn't even understand merge sort.
I was struggling with for loops and indexes, and then suddenly something clicked in my head, like someone flipped a switch, and i understood everything i was explained, all at once. It was like enlightenment, like pure magic.
I had sudoku solver implemented by the end of the lecture. Linked list, hash map, sets, social graphs, i got all of these implemented later, it wasn't a problem anymore. I later got an A for my diploma.
Thank you @dementiy, you were the reason for my career to blast off.7 -
Someone wrote a piece of code half a year ago. It's fuckin complex and recursive. And uncommented. Today it's my job to figure out WHY and HOW it works.
If it wasn't clear before, that someone who wrote it was me. I'm not sure if I was on some substances back then, but that shit is fast and I have no clue how I was able to create it. Perhaps it was the coffee overdose...
However, wish me luck figuring this thing out.6 -
There are two types of people in this world: those who understand recursion and those who don’t understand that there are two types of people in this world

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....

My own programming language (still WIP). I got SO excited when I found recursion worked, I even got the simplest factorial recursive function wrong. And then again, once arrays worked, bubble sort it was. I shit you not, once I saw all the numbers printed in order, I had to stand up and walk or I would have jumped out of the chair in excitement.
In case someone is interested, I use LLVM for the backend.4 -

Was joking with my sister about who has more steps. She had done more steps so far, so I said that I would walk 20 times around the McDonald's, where we were going to eat. She replied that she would walk 50 times around it, so I said that I would walk 2 times more around it than she would. She then said, that she would go once more around it. In the end, I explained recursion and infinite loops to her. Her comment was "großer Blödsinn" (German) -> "big bullshit".4

A dev team has been spending the past couple of weeks working on a 'generic rule engine' to validate a marketing process. The “Buy 5, get 10% off” kind of promotions.
The UI has all the great bits, drop-downs, various data lookups, etc etc..
What the dev is storing the database is the actual string representation FieldA=“Buy 5, get 10% off” that is “built” from the UI.
Might be OK, but now they want to apply that string to an actual order. Extract ‘5’, the word ‘Buy’ to apply to the purchase quantity rule, ‘10%’ and the word ‘off’ to subtract from the total.
Dev asked me:
Dev: “How can I use reflection to parse the string and determine what are integers, decimals, and percents?”
Me: “That sounds complicated. Why would you do that?”
Dev: “It’s only a string. Parsing it was easy. First we need to know how to extract numbers and be able to compare them.”
Me: “I’ve seen the data structures, wouldn’t it be easier to serialize the objects to JSON and store the string in the database? When you deserialize, you won’t have to parse or do any kind of reflection. You should try to keep the rule behavior as simple as possible. Developing your own tokenizer that relies on reflection and hoping the UI doesn’t change isn’t going to be reliable.”
Dev: “Tokens!...yea…tokens…that’s what we want. I’ll come up with a tokenizing algorithm that can utilize recursion and reflection to extract all the comparable data structures.”
Me: “Wow…uh…no, don’t do that. The UI already has to map the data, just make it easy on yourself and serialize that object. It’s like one line of code to serialize and deserialize.”
Dev: “I don’t know…sounds like magic. Using tokens seems like the more straightforward O-O approach. Thanks anyway.”
I probably getting too old to keep up with these kids, I have no idea what the frack he was talking about. Not sure if they are too smart or I’m too stupid/lazy. Either way, I keeping my name as far away from that project as possible.4 -

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 -
What the hell was I thinking at when I wrote this nice interface wrapper...

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 -
I had a coworker that was a real asshole. I noticed that often, during git merges, he removed part of the code I wrote.
So I had to spend a lot of time copying and pasting my code from git history in order to restore it.
I complained about that but he answered it happened by mistake. In reality that happened so often that he had to done it deliberately.
Btw, I did a little revenge. One day I discovered he didn't feel very comfortable using recursion. Thereafter, every time I needed a small loop I created a recursive function doing the same thing.
Fortunately, after some months I found a better job. I hope he is still debugging that code.4 -
Crazy code.
You know when you come across some code, where you think: “I kinda see what you were going for, but it’s still hella dumb though...” right?
Currently doing some work on an F# backend, and the dev clearly knew enough of the language, but their code makes me question a lot.
The problem is simple: use a third party tool to generate images of each page in a pdf.
Said tool supports:
1. Querying the number of pages
2. Getting all pages as separate images in a single invocation
Can you guess how the dev solved it?
They’ve recursively incremented a page number, called the external tool to grab the image of that page.
“But how does it know when it’s run out of pages?” I hear you ask.
Simple. Catch the inevitable exception, and check against a hardcoded string literal to see whether it says “must be before the end of the document”.
I shit you not.
I nearly had an actual seizure when I was debugging some semi-related code and ended up in this wonderland of fuckery.
The recursion and pattern matching was flawless though, yet the tool’s website clearly states the supported functionality.
The whole thing feels like they tried to do it the right way, but couldn’t be bothered / couldn’t get it right, so they ended up creating this insane bit of madness.5 -
Top 3 times:

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 -

Felt like a real badass in middle school when I made my first .bat script that would recursively open itself. Took only two words. Four if you wanted exponential recursion rather than linear. And I came up with it by myself.
Cheesiest thing ever, but I really loved freaking people out by opening it and just watch windows grind to a halt as it would run out of ram opening thousands of terminal windows. Hell, it still gives me a kick today when I show it to people the first time :D7 -

Despite common sense, I think technology is not making our lives easier. It's just build chaos on top of chaos.
Take server-side programming for instance.
First you have to find someone to host your thing, or a PaaS provider. Then you have to figure out how much RAM and storage you need, which OS you're going to use. And then there's Docker (which will run on top of a VM on AWS or GCP anyway, making even less sense). And then there's the server technology: nginx, Apache (and many many more; if, that is, you're using a server at all). And then there are firewalls, proxies, SSL. And then you go back to the start, because you have to check if your hosting provider will support the OS or Docker or your server. (I smell infinite recursion here.)
Each of these moving parts come with their own can of worms in terms of configuration and security. A whole bible to read if you want to have the slightest clue about what you're doing.
And then there's the programming language to use and its accompanying frameworks. Can they replace the server technology? Should you? Will they conflict with each other and open yet another backdoor into your system? Is it supported by your hosting provider? (Did I mention an infinite recursion somewhere?)
And then there's the database. Does it have a port to the language/framework of your choosing? Why does it expose an web interface? Is it supposed to replace your server? And why are its security features optional again? (Just so I have to test both the insecure and the secure environments?)
And you haven't written a single line of code yet, mind you.4 -
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 ?

I'm absolutely loving the fact that my university is making me take their intro to programming course this fall when I've taken 5 programming classes in high school and already have intro to programming credits from a different university. Did I mention that I passed the AP Computer Science exam before taking even more courses? Do they not understand that I do in fact understand how to use recursion(the most advanced topic in their intro course) and don't need to spend a semester relearning what I already know? For Christ's sake they don't even get into OOP in that course.3

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

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!2 -
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.

Today I wrote the most epic code.
The kind that breaks your brain, but when you're done with it you know it's time to go home and kick back coz you've done good.
It used recursion, did backflips to avoid unnecessary db calls, featured no code repitition. Hell I even commented the business rules it was following in there to explain what was happening.

My Gripe With Implicit Returns
In my experience I've found that wherever possible code should be WYSIWYG in terms of the effects per statement. Intent and the effects thereof should always be explicit per statement, not implicit, otherwise effects not intended will eventually slip in, and be missed.
It's hard to catch, and fix the effects of a statement intent where the statement in question is *implicit* because the effect is a *byproduct* of another statement.
Worse still, this sort of design encourages 'pyramid coding recursion hell', where some users will first decompose their program into respective scopes, and then return and compose them..atomically as possible, meaning execution flow becomes distorted, run time state becomes dependent not on obvious plain-at-sight code, but on the run time state itself. This I've found is a symptom of people who have spent too much time with LISP or other eye-stabbingly fucky abominations. Finally implicit returns encourage a form of thinking where programmers attempt to write code that 'just works' without thinking about how it *looks* or reads. The problem with opaque-programming is that while it may or may not be effortless, much more time is spent in reading, debugging, understanding, and maintaining code than is spent writing it--which is obviously problematic if we have a bunch of invisible returns everywhere, which requires new developers reading it to stop each and every time to decide whether to mentally 'insert' a return statement.
This really isn't a rant, as much as an old bitter gripe from the guy that got stuck with the job of debugging. And admittedly I've admired lisp from afar, but I didn't want to catch the "everything is functional, DOWN WITH THE STATE" fever, I'm no radical.
Just god damn, think of the future programmer who may have to read your code eventually.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.
... or is that just me? ...2 -
I just watched a video where a guy used a homemade band saw made of wood to make another homemade band saw made of wood. This is the very definition of recursion, amirite?3

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 -
My university had a Programming Fundamentals course in the first semester and we got assigned this grumpy lady who demanded respect and would always claim she was the best at programming among her colleagues, had an obnoxiously snobbish tone and had a habit of forcing unneeded nonsensical sarcasm everytime one of us stepped up to ask her a question.
She taught C++ and I'm not saying she didn't know her stuff or anything; I respected her regardless (because she was my teacher), but she would mix up C classes in and insist that that was the right way to do it and had no consistent programming style.
Once she got so fed up with our class that just to prove her point that we're all dumb and worthless (she hated us a lot, yeah) that she started explaining binary trees and recursion out of the blue and gave us assignments for them... even though they weren't going to be covered that week. It soon became a shitfest, to be honest.
But on the plus side, because I didn't wanna listen to her lectures I pulled two all-nighters and covered the semester's worth of C++ and started napping in a corner in her class. She never had personal beef with me so I was thankful for that but her being the way she was helped me learn C++ with more motivation and vigor than I normally would have and also let me earn some change because my classmates couldn't understand her classes and wanted me to explain whatever she covered. -
I regret ever picking my CS major every time I stare at my VS Debugger and am stuck reading the values stored in a List<Int>. Why, List<Int>, as the backing for my shortest path, do you not have the proper values after I walk my tree.
I have lovingly set up my Priority Queue. I have followed the class notes and lectures.
Oh why, my List, have your forsaken me?
Oh.
It's a recursion bug. I'm not updating nodes properly.
I'm a dumb ass.2 -
When I first met the Logo turtle I was hooked. Then learned Pascal. Saw recursion and my brain exploded. 23 years and still love it every day 🐢

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 -

Week 1 day 3 and 4.
I didn't feel like I did a whole lot yesterday so I just pushed it into today. In the past I tried to program for hours everyday and expect to keep up my stamina for it but it didn't work so this time I'll just take days off every now and then and see if that works at all. Yesterday was one of those, the only thing I did was watch some videos on OOP and practice some more with OOP and recursion.
As far as today goes I started sketching our the ideas for my own personal app I hope to develop once I get the skill set. I tried to focus on looking at it not just from the perspective of a developer but also a user and a marketer to see vialibity and such but I have a LONG time to go before I can get my idea rolling. I decided to push starting the actual course until tomorrow because Ina small questionnaire before you go into it it asks if you're familliar with threading and networking, which I am not. So that was my main focus today, expanding my base Java skill set. If any Android Devs can give from their experience want I need to know I would love that but other than that I feel pretty good about what I did today. -
they say i was a natural at programming. i like it, i understand problems easily and im able to find a solution for it. but so was math, and chemistry. basically anything that has problem solving so i wasn't into programming that much.
until i joined my first competition. man that was an eye opener. we had a deadlock tie with the other team, and there was this one problem that was a tie breaker. sure enough we both was able to solve it. but the judges ruled in our favor because of one thing, i used recursion! man that was fun. the looks on their faces.
and i was hooked on that euphoric feeling. that was my drug. now , a decade or so later, im still addicted to that drug -
*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. -
An old sysadmin configured the idrac interface of a company VMware server to get the IP address trough DHCP. Of course, without a valid IP, the server doesn't start. For you, where was hosted the VM with the DHCP server?1

It was one of those "I need more coffee days"..
I was writing some checking function called "check" (now to clarify my company is not coding oop style so no classes etc.) And as I went on I included another file for some functions and what not. Pretty normal stuff right? Right. In that file I required there also was a function called "check".
Guess who tried to use the "check" function of the imported file in the "check" function?! Right! A Fucking genius aka. me!!
So I tried to figure out why the page wouldn't load and why the server was starting to lag more and more.
After killing all the apache tasks three times i finally realized what I did.
Took me 10 minutes to figure out that i was causing endless recursion. That day wasn't my best and clearly not filled with enough coffee.
PS: yes I know oop would have probably eliminated the possibility for this but I'm just adapting to the coding style of my company as I can't really change things since I'm just an intern.1 -
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
-
"String reverse with recursion" - I know it's a small thing for seasoned coders but back when I was starting It opened tons of possibilities.
-
self refrencing tables awesome concept but it pisses me off that mysql doesnt support "select with" query i had to think about writing recusive functions that builds a tree of n level i must say im kinda proud :p

I just found this in the code I'm working on:
function checkDateValidity() {
function checkDateValidity() {
...
}
}
Obviously a bad copy/paste. Not even sure how it was working before; it probably wasn't.1 -
Me: *watches programming video on Y-Combinator*
Also Me: "why the heck are they talking about recursion and not funding startups?"2 -
We are dependent on dependency injection and package management... which also comes with a lot of dependencies installed by another package manager1
-
Yeah it's just me.
*when your recursion function suddenly worked and you still can't figure out why it worked...*
Guess I need to improve on my algorithms more. Just can't wrap my head around even a quite simple recursion. I'm certain this won't last long. -
val true : bool = isFrustrated(me : Human)
1) Honestly fuck SML. Who's goddamn idea was it to make a useless fucking programming language that does absolutely nothing relevant unless you're trying to learn recursion. Who's fucking idea was it to not be able to even have side effects. And who gives a shit if you can explicitly declare the type of variables on every single fucking line that's what comments are for if you really need it. All this is aside from the fact that nobody ever has been like "OH UNMUTABLE TYPES? WOW IM SO HAPPY THIS IS SO USEFUL". At this point I feel like SML is basically a DFA - ABSOLUTELY FUCKING USELESS
2) Aside from that, who's idea was it to duplicate two classes. There's 15-122 (Principles of Imperative Computation) and 15-150 (Principles of Functional Programming). So far the ONLY fucking thing different is we learned about work and span in 15-150 - OTHER THAN THAT ITS LIKE TAKING THE EXACT SAME COURSE. BUT AGAIN. So then I have to fucking sit in lecture and pay attention for that tiny bit of information that is new amongst the giant cesspool of information that isn't. BECAUSE I ALREADY LEARNED IT.
Oh and did I mention that both classes are required to graduate as a CS major? Fuck me.
Thanks devRant for helping <3
Edit: We are 4 weeks into the semester so you'd expect we'd have gotten into the new stuff by now right????5 -
Imagine you have a dream about dreaming about unfinished code that triggers recursion, because it is unfinished and that is why you are dreaming about it.

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
😣7 -
Sometime I feel, god forget to write proper toggle command for me.
For others it is random, for me it is static. One sad life. Only hope is system run out of memory because it is recursion with no ending.
here is the dev-rant
After fucking with Laravel Passport for 3 days, I finally manage to find a way to do multi auth.
Yeah! dude I am the guy who is going to write a tutorial for that. So, you must -- this rant.1 -
Recursion: Good or bad? I mean, it's very few lines, efficient and pretty but can be so damn hard for others to read and debug.3
-
Apparently my superpower is writing exponential time algorithms to solve puzzles and games. If you need someone to write a recursive DFS to solve your shitty word search, hit me up.

Seems like latex does not like recursion. Defined a command as itseld by accident and got lots of strange error. Will there be a time where i can accept that copy-pasting code only generates problem?
-
well... Fuck you ackermann and your damn interesting function!
Spent three hours searching for an error in rasoning but well... Who'd have guessed...
FUCK! I need to get my stuff done... Fuck!
