Search - "recursion again"
-
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.8 -
I'm 20, and I consider myself to be as junior as they come. I only started programming seriously in June 2016,and since then, I've been doing mainly Android Work, and making my own servers and backends(using AWS/Firebase nd stuff).
For the first time in life, I was approached by a recruiter for a company on linkedIn. They "stumbled upon" my Github profile and wanted to see if I was interested in an internship opportunity. This company is an early stage start up, by that I mean a dude with an idea calling himself the CEO and a guy who "runs a tech blog" and only knows college level C programming (explaination follows).
So they want me to make the app for their startup. and for that, I ws first asked to solve a couple problems to prove my competence and a "technical interview" followed.
They gave me 3 questions, all textbook, GCD of 2 numbers, binary search and Adding an element to the linked List, code to be written on a piece of paper. As the position was that of an Android Developer, I assumed that Java should be the language of choice. Assumed because when I asked, the 'tech blogger' said, yeah whatever.
But wait, that ain't all, as soon as I was done, Mr. Blogger threw a fit, saying I shouldn't assume and that I must write it in C. I kept my cool (I'm not the most patient person), and wrote the whole thing in C.
He read it, and asked me what I've written and then told me how wrong I was to write 2 extra lines instead of recursion for GCD. I explained that with numbers large enough, we run the risk of getting a stackoverflow and it's best to apply non recursive solution if possible. He just heard stackoverflow and accused me of cheating. I should have left right then, but I don't know why, I apologized and again, in detail explained what was happening to this fucktard. Once this was done, He asked me how, if I had to, I'd use this exact code in my Android App. I told him that Id rather write this in Java/Kotlin since those are the languages native to Android apps. I also said that I'd export these as a Library and use JNI for the task. (I don't actually know how, I figured I can study if I have to).
Here's his reply, "WTF! We don't want to make the app in Java, we will use C (Yeh, not C++, C). and Don't use these fancy TOOLS like JNI or Kotlin in front of me, make a proper application."
By this I was clear that this guy is not fit to be technical lead and that I should leave. I said, "Sir, I don't know how, if even possible, can we make an Android App purely in C. I am sorry, but this job is not for me".
I got up and was about to leave the room, when we said, "Yeah okay, I was just testing you".
Yeah right, the guy's face looked like a howling monkey when I said Library for C, and It has been easier for me to explain code to my 10 year old cousin that this dumbfuck.
He then proceeded to ask me about my availability, and I said that I can at max to 15-20 hours a week since my college schedule is pretty tight. I asked me to get him a prototype in 2 months and also offered me a full time job after I graduate. (That'd be 2 years from now). I said thank you for the offer, but I am still not sure of I am the right person for this job.
He then said, "Oh you will be when I tell you your monthly stipend."
I stopped for a second, because, money.
And then he proceeded to say 2 words which made me walk out without saying a single word.
"One Thousand".
I live in India, 1000 INR translates to roughly $15. I made 25 times that by doing nothing more than add a web view to an activity and render a company's responsive website in it so it looks like an app.
If this wasn't enough, the recruiter later had the audacity to blame me for it and tell me how lucky I am to even get an offer "so good".
Fuck inexperienced assholes trying shit they don't understand and thinking that the other guy is shitsworth.10 -
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 -

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 -
> Advice to new coders
Don't worry over picking language A or B.
Just pick A, use it for a month, then move on to B.
In a normal 3 year college degree you'll try multiple languages, some of which you'll never use again, and they'll each teach you something.
I had classes in Java, C, C++, C#, Prolog, Assembler, F#, JS.
Never used F# again and no one uses Prolog. But they were great for learning recursion and logic.
It's not like you take "a step down a bad path" if you pick a language you're never gonna use again.
You'll also learn new stuff on the job. We have one team that uses Go and one that uses Rust. None of the devs ever studied those languages. They were mostly former Java devs who leaned on the job.2 -
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 -
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
Never again3 -
They should rename computer science at secondary school/a level to "recursion in action"... I really don't enjoy having to learn fundamentals again...

Trying out the new version of fasm, I realize it's good, and conclude I should update my code to work with it as there's small incompatibilities with the syntax.
So, quick flat assembler lesson: the macro system is freaking nuts, but there are limitations on the old version.
One issue, for instance, is recursive macros aren't easily possible. By "easily" I mean without resorting to black magic, of course. Utilizing the arcane power of crack, I can automatically define the same macro multiple times, up to a maximum recursion depth. But it's a flimsy patch, on top of stupid, and also has limitations. New version fixes this.
Another problem is capturing lines of code. It's not impossible, again, but a pain in the ass that requires too much drug-addled wizardry to deal with. Also fixed in new version.
Why would you want to capture lines of code? Well, because I can do this, for instance:
macro parse line {
··match a =+ b , line \{
····add a,b;
··\}
};
You can process lines of code like this. The above is a trivial example that makes no fucking sense, but essentially the assembler allows you define your own syntax, and with sufficient patience, you can use this feature to develop absolutely super fucking humongous galactic unrolls, so it's a fantastic code emitter.
Anyway, the third major issue is `{}` curlies have to be escaped according to the nesting level as seen in the example; this is due to a parser limitation. [#] hashes and [`] backticks, which are used to concatenate and stringify tokens respectively, have to be escaped as well depending on the nesting level at which the token originates. This was also fixed.
There's other minor problems but that gives you sufficient context. What happens is the new version of fasm fixes all of these problems that were either annoying me, forcing me to write much more mystical code than I'd normally agree to, and in some rare cases even limiting me in what I could do...
But "limiting" needs to be contextualized as well: I understand fasm macros well enough to write a virtual machine with them. Wish I was kidding. I called it the Arcane 9 Machine, A9M for short. Here, bitch was the prototype for the VM my fucking compiler uses: https://github.com/Liebranca/forge/...
So how am I """limited""", then? You wouldn't understand. As much as I hate to say it, that which should immediately be called into question, you're gonna have to trust me. There are many further extravagant affronts to humanity that I yearn to commit with absolute impunity, and I will NOT be DENIED.
Point is code can be rewritten in much simpler, shorter, cleaner form.
Logic can be much more intricate and sophisticated.
Recursion is no longer a problem.
Namespaces are now a thing.
Capturing -- and processing -- lines of code is easier than ever...
Nearly every problem I had with fasm is gone with this update: thusly, my power grows rather... exponentially.
And I SWEAR that I will NOT use it for good. I shall be the most corrupt, bloodthirsty, deranged tyrant ever known to this accursed digital landscape of broken souls and forgotten dreams.
*I* will reforge the world with black smoldering flame.
*I* will bury my enemies in ill-and-damned obsidian caskets.
And *I* will feed their armies to a gigantic, ravenous mass grave...
Yes... YES! This is the moment!
PREPARE THE RITUAL ROOM (https://youtube.com/watch/...)
Couriers! Ride towards the homeland! Bring word of our success.
And you, page, fetch me my sombersteel graver...
I shall inscribe the spell into these very walls...
in the ELEVENTH degree!

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
