Proud moment today when I actually made an hsv to rgb conversion algorithm by following a formula rather than copying code from stack overflow

I spent three hours coding some algorithm and then looked it up on Stack Overflow out of curiosity. Big surprise. Someone did the exact same thing but more effeciently, and had all the code in his answer on SO.
Ughhhhhhhh 😓4 -
There is NOTHING more satisfying than having an algorithm suddenly click while you are in the shower.

This spring I was working on a library for an algorithm class at uni with some friends and one of the algorithm was extremely slow, we were using Python to study graphs of roads on a map and a medium example took about 6-7h of commission to finish (I never actually waited for so long, so maybe more).
I got so pissed of for that code that I left the lab and went to eat. Once I got back I rewrote just the god-damned data structure we were using and the time got down to 300ms. Milliseconds!
Lessons learned:
- If you're pissed go take a walk and when you'll come back it will be much easier;
- Don't generalize to much a library, the data structure I write before was optimized for a different kind of usage and complete garbage for that last one;
- Never fucking use frozen sets in Python unless you really need them, they're so fricking slow!3 -
I just experienced the opposite of rant.
I spent 1 entire day ranting about a algorithm I couldn't write with no issues, it occupied all my mind and got me pissed of.
And today, I rewrote it entirely, and it works perfectly everywhere.
I was like : "No it can't work here. Oh ok", "And here's the bug ! No ? Nice.", "Don't tell me it'll work here. I'm a God".
That's why I love being a dev :D
Thank you, you freaking problem I had !7 -
Juste design a new algorithm to evaluate the chance of a project (any kind of project) will exceed the budget (time of cost). This algorithm been proven to be right almost all the time.

Let's see the coder in you.
If I give input: 1 output: 2
If I give input: 2 output:1
Only these two test cases needed.
You should not use control structures such as if,else,for,while,switch etc. (The answer is simple) (Don't cheat)

Spent two days debugging my algo to figure it was a problem with the colors they picked and my logic was fucking flawless!
Sweetest feeling ever :D
I'm sort of color blind so I never check colors and I'm really straight about it with everyone: I don't pick colors.
Its a rant with a happy ending :)6 -

An overflow in C, the program was writing 16 Bytes in an array of length 10 due to some mistake.
The problem was this ended up overwriting another place in the memory that was used by another algorithm to perform calculations... So we thought that the algorithm was buggy all along.2 -

"Change your algorithm"
Answers like this are why Stack Overflow almost becomes worthless when asking questions. I asked for some clarification why my code, which reads some files and outputs another, was hitting System.OutOfMemory exceptions. And that was the response I got.
"Change your algorithm"
How? In what manner should I be seeking to change my algorithm? OBVIOUSLY I SHOULD CHANGE MY ALGORITHM YOU WASTE OF OXYGEN. That was a given by the exception my program threw!
I swear to god, SO has got to be one of the most unwelcoming, condescending sites on the internet.4 -
I finally finished my implementation of a suffix array construction algorithm! 😄
It takes about 30 mins to process 1GB of text and uses all available RAM, but it works! 🎉
Now I can optimize it, the original algorithm is 3x faster.

me: *codes for a few hours*

A funny story I just remember while my code is compiling :
Back in high school, in Math, we were taught how algorithm works, and we made some exercises with practical examples.
I didn't know anything about it back then, so was curious. Was pretty fun, but one day, my teacher said that a IF is a loop. I said "no, this is a test" but she keeps saying that it was a loop, ignoring me (I dunno if she actually heard me) and no one actually noticed it as she repeated it several times (while I was saying that it's not). I just gave up trying to say it's wrong.8 -
Hardest thing about software development to me is estimation of time needed to complete. There should be an algorithm that knows to estimate better than me, shouldn't it? Like google maps navigation knows precisely in advance when I will arrive somewhere taking a car or a train, perhaps they could do my development estimates for me?9

concerned parent: if all your friends jumped off a bridge would you follow them?

It was my thesis defense and I've made a pretty complex algorithm of sorting out data to their respective tables. One panelist told me that it is not an algorithm but just a collection of for loops and if statements. An algorithm should contain mathematical equations he said. I facepalmed during the course of interrogation.

So during a test I was to write an algo of binary search tree traversal and I got a zero....Why? Cause I wrote a recursive algorithm and also because I wrote "English" instead of pseudocode, which she thought is called algorithm and on showing her the exact same recursive Algo on various websites and books, she just declared all of them wrong1

Facebook's algorithm is so bad that I can't believe that. In the past few days I marked ~20 posts from the same person with the same/similar content as "Hide post - see fewer posts like this". And now, not that I see fewer of these posts, they are literally throwing all such posts of that person to my feed. I know that I can unfollow this person but I don't want to. I just want to filter out these specific posts (they are all the same, some link, image of an old black and white photo and some description).5

I think God is a developer. I have to say a most impressive feat, even for God, is the idiot algorithm. It has persisted through millennia of attempts to remove it, but it just keeps refining itself. While it's incredibly brief, its functions are yet to find an environment in which they cannot operate. It's full adaptable to any task, impressively modular, and self replicating.
No matter how what problem you present it with the idiot algorithm can always find a solution. It never leaves well enough alone. It can even give you an answer before everything is fully processed!4 -
One of my favorite things to do in Secondary School was to go around telling people I had written a program that uses the 'Doomsday Algorithm' which sounded really cool and always scared those who didn't understand it.
Truth is, the 'Doomsday Algorithm' is just an Algorithm that used to determine the Day of the Week of a given date.
I wrote this when I was 13/14 years old and I'm still super proud of it today.... well I mean I probably would be if I could read my own code.1 -
So in my last post I was angry that I didnt know many algorithms or how to make one, so you guys inspired me to learn about them and I found a course I'm gonna take about algorithms and such. I'm incorporating it into my learning schedule so let's hope this leads to me not being stupid.3

Looks like I got dislike-banned as well... eventhough I only used it where appropriate.
I understand that our almighty gods dfox and trogus implemented this to fight bots and mischievous downvote cunts, but why not inform the user affected by it?
I fucking hate these silent bans, just like Twatter and YouTwat do it... you feel like you posted something but in reality it disappears and you're not even aware of it.
Man, nowadays a lot of people behave like bots thus I can't blame The Algorithm™...3 -
which *git* diff algorithm is your default and why?
## default (myers)
The basic greedy diff algorithm. Currently, this is the default. if you don't know whart you are using, this is it (and it sucks)
## minimal
Spend extra time to make sure the smallest possible diff is produced.
##patience
Use "patience diff" algorithm when generating patches.
## histogram
This algorithm extends the patience algorithm to "support low-occurrence common elements".4 -
I’m really liking the Algorithm Design Manual so far, except for the fact that there’s not a glossary somewhere for “random mathematical symbols you have probably never had to deal with but we will use in psuedocode examples”1

We had to finish a student project, our project leader had done some work on the project before and his algorithm to detect an event was complete bullcrap.
I took it in my hands to rewrite the algorithm with the risk that it doesn‘t work and i hadn‘t done any work i could show, which would result in a bad grade.
Luckily my algorithm worked better in orders of magnitude and we managed to deliver on time -

No idea about my score -
Few days back, I developed an app for a client where users can buy textile designs online.
The designs to be uploaded on the server must be square to display correctly on the app. so I had to make them square manually (by either pattern repetition or by filling extra space).
I was like "fuck me!", 800 design image to make it square and each takes like 1 and half minute. I did uploaded 30 to 40 images and then...
I got really frustrated and I was lazy to make more designs square anymore.. So I developed an algorithm that would identify the type of design and then it automatically makes it square by self decision.
so that was my little anti-laziness for my big laziness. -

Another GeeksForGeeks rant
Wisecrack got me a bit interested in primes (just a passing interest). I looked up their python implementation of "Sieve of Atkin". Wow, is it bad.
First of all, they use PascalCase instead of underscore_natation so that's points off right there.
Their function takes a limit as a parameter (pretty obviously).
Their program breaks if you pass a prime number as a limit. That's right, if you give it a 2, it breaks. Pretty pathetic.
Reading the comments, their Java implementation is wrong too.
For fucks sake guys, if you're going to have an algorithm blog at least write good algorithms.6 -

Maybe the twitter developers getting laid off should join spotify in their quest for a simple shuffle algorithm that they failed to develop or maybe just are not allowed to ship due to corrupt company politics?
As Spotify's algorithm sucks from a listener's perspective (major music industry might like it though), I have to rely 100% on curated playlists, and without shuffle, I have to listen in the exact order that they were made. Why not? We did the same when we put actual records on a record player. Who needs shuffle? Who needs streaming anyway? I'm gonna get a pair of turntables or just listen to MP3 files again!
There is a "new idea" thread in the spotify community forum started in 2020 (following up on an earlier 2012 suggestion), a feature request for the "option to have a true shuffle" that already has 70+ pages, tagged as trending in 2021 with the friendly stalling message:
As this idea has gathered a fair amount of votes, we've discussed it with the relevant team once again. We actually want to take a closer look at what you're experiencing and get some of you in touch with our devs.
Good luck everyone. If I still use Spotify in 2023, I can probably repost the very same status again one year later when the app will still lack a simple shuffle option, no?

I am a cs student at first class. Obviously we take an algorithm lesson. However, despite we have learned all things related to OOP , we didn't even learn switch case statement not even bubble sort algorithm or anything related to the algorithms. Because of that in my free time I learn this stuff individually. I know we will learn these things in the second class but it doesn't make sense to program anything without knowing them because you need to use them. You can use standard library but that doesn't mean you don't need to know how that works.
