Colleague: "Python is slow..too much slow."

Then I look at the code:

Eight nested for loops, inside two of them, two function calls and three list comprehension. That function has 2 nested loops and two "objects.all()" Django method, plus a list comprehension too..

Yep, Python is slow.

I've seen people do more than 4 as well though

A substring problem? Here, have 3 nested for loops 😏😏

Please for the love of god name your variables in a sensible way! How the FUCK am I supposed to read your shitcode if you decide to write 6 (!!!) nested loops with variables each named by exactly one character. With no comments whatsoever!

I would rather crack password hashes than this nonsense.

Going to forums asking for help as to why my nested for loop wasn't working correctly after the first loop only to realise I was using the variable i for both loops...

Felt like an absolute twat

Oh boy 😂

Having to review an offshore C++ codebase made in Romania that the company I worked for they bought to control a wifi module on a complex RF mobile tech device that I can't legally give more details on.

If I could legally post this masterpiece, or should I say masterpiece-of-shit, all of you C++ dev would instantly get AIDS and all the existing types of cancer upon browsing it for 2 minutes.

It's laughably bad and unmaintainable. One of my colleague called it "the perfect example of human obfuscation" and it fits perfectly.

Think of a 100k LoC main function with nested loops and ifs with random sleep values, 1000 values of hardcoded 32 bits arrays declared globally in the first 10k lines for unknown reasons. Comments in Romanian mixed with english. Somehow, this shit works by some miracle.

The worst intern you can think of, while being piss drunk, could do better and it's no joke.

just started an AI project (yes I know, very descriptive). should i have 20 nested for loops???

I used a goto. Couldn't figure out how to solve it with loops, due to nested switch, if, for..

FUCK

Have you ever worked with people that constantly asks you what to do? People who are in the same spot as you, I mean.

- Hey, you should start debugging this while I finish this menu

The other day, I customer of ours asked me to try to improve the performance of an application of his in a particular method. The method in question taking more than 5 minutes.
I took a look at what it did in the profiler, and it shocked me. More than 100k selects to the database, to retrieve 116 records...
I took a look at the code... Scores of selects in nested loops inside other nested loops inside of... That seemed normal to them...
At the end after we improved it's performance it took 3 seconds...
What shocks me the most is that the customer is a developer himself, really knowledgeable and has an order of magnitude more experience than I do. Am I too anti "worthless database round-trips"? Is that normal? :S

If this isn't the worst thing.

I was asked to develop a WordPress plugin as an intern developer and I've been on it since last week. I got stuck when i finally had the loops running but couldn't find a way to format the output without overwriting the existing values on each iteration.

For the last one week I've been showing the progress on my code to the CTO and this is how it has been.

Me: Hello. Everything is coming along fine, I have most of the functions running properly, do you mind looking into the algorithm?

CTO: Oh not at all, let's see what you got. Omg great code for an intern. I think you should add a new variable there and maybe clean up that function over there because it's deprecated now and yeah HaHa, Great work.

Me: Thanks xD I'll have it finished latest next week.

CTO: Oh great. I can't wait to see what you'd have by next week so we can install it on our WordPress.

*Next finally week comes and I'm done with the code.

Me: Hello, I'm done with the entire code! Want to take a look? The plugin works just exactly as described.

*CTO takes a look

CTO: Omg?

Me: Omg?

CTO: This is completely bad programming practice, so you are running 4 nested loops that all send queries to our data base and make changes to data. This would have a very drastic effect on the server considering the traffic we get.

Me: But you saw this exact code last week and said it was okay, I only changed some CSS since the last time.

CTO: Omg, we can't accept this, you have to develop it again from the scratch without using those loops and queries.

Me: What? Okay, fine. Any hints?

CTO: Yes.

Me: What?

CTO: Just start. That's the greatest hint I could ever give. And also, always have a plan before you begin.

Me: Yeah, thanks for those. It's the first time I'm hearing them and they would totally be applicable to building this thing.

My loop checked a variable, then the next 5 nested loops checked it again, then started over. It was a hard coded variable I forgot about.

I just made my code OCD

I had the oppertunity to join a non profit organization to help them automate stuff instead of serving the army. One of their core applications got rewritten like a year ago from a terrible and very old Symfony stack to Laravel / React.

The guys who were in charge for the rewrite didn't really adapt the mindset of either MVC for Laravel nor the component idea behind React. There are a few controllers in the backend, but they sometimes have functions defined which would clearly belong in a model or service class. They rarely defined relationships on models, instead they're joining the tables together for the same effect. The frontend rendering mostly happens in for loops over the returned array from the API instead of breaking things down into little components. This ends in components which have sometimes over 1000 lines with super-nested logic in it.

But I did find my favorite piece of code today in of the controllers. Some many questions ...

Fuck NodeJS. I don't want you to be asynchronous sometimes. My gahwd I need like 3 deep nested loops just to get you to make a request and compile a damn JSON of requests.

I'm learning Golang goodbye forever node.

A long long time ago ( 2007 I think ) I worked for a company that made landing sites, so basically an email campaign would go out, users would be sent to a 1 page website with a form to capture their data, ready to be spammed even more. You know how it was back then.

So I worked with a guy who we had just hired, I didn't do the hiring but his CV checked out, so I gave him one of my tasks. Now most pages were made with js and html, with a PHP backend ( called with Ajax). Now this guy didn't know PHP so I was like all good, ASP works too at the end of the day we don't judge, we do like 2 or 3 of these a day and never look at them again. So he goes of and does is thing.

3 weeks later, the customer calls up to me they still haven't received their landing page. Ok so he probably forgot to email the customer np, I tell him to double check he has emailed the customer. Another week goes by end the customer calls back, same problem. At this point I'm getting worried, because we're days away from the deadline and it was originally my task.

So I go back to the guy and I tell him I want that landing page so I can send it myself, half thinking to myself that we had a freeloader, that guy that comes in to companies for 3 weeks, doesn't work, but still cashes his pay. But no, this was much worse.

So he tells me he has finished yet. I ask him why, what's the blocker ? You had 4 weeks to tell me you were blocked and couldn't progress. And his answer was simply, because I wasn't blocked I have been working on it this whole time. So I tell him to zip his project up and email it to me. We didn't do SVN or git back then, simply wasn't worth it. So he comes back to me and says the email server is telling him attachments can't be bigger then 50mb. At this point I'm thinking he didn't properly sized the art or something, so I give him a flash drive to put it on.

When I then open the flash drive, the archive is 300mb, thinking to myself, the images weren't even that big to begin with.
So I open it up, and I don't even find any images, just a single asp page. About 500mb. When I opened that up and it finally loaded, I saw the most horrendous things ever.

The first 500 lines was just initializing empty vars. Then there was some code that created an empty form with an onChange event that submits the form. After that.. it was just non stop nested if's. No loops, no while, for, foreach, NO elseif's, just nested if's, for every possible combination of the state the form could be in. Abou 5000 of them, in a single file. To make matters worse, all the form ( and page ) layout was hardcoded in the if's. Includes inline css, base64 encoded images, nothing but as dynamic, based on the length of the form he changes the layout, added more background etc. He cut the images up for every possible size of the page and included them in the code.

I showed it to my boss, he fired the guy on the spot. I redid the work from scratch, in under 4 hours. Send it to the client. they had no ammends to make, happy as Larry. Whish I kept the code somewhere.

Morale of the story, allways do a coding test on interviews, even if small things just to sanity check.

Actual production code:
while(1):
//A few lines of code here with a conditional break.
while(1):
//More code.

Have you ever just had nested infinite loops...

This is so annoying, I had 9 diff. jobs the past 2 years and this is my 10th and if this doesn't change I might reconsider my options again.

I came to work at a company that pays me like a Junior and treats me as an intern. My 20yo "boss" who acts as a project owner/lead dev doesn't want to learn anything new and sees any improvement as a waste of money. The problem is he thinks hes a great programmer but he doesn't know shit. Im mainly working on the Laravel installation because "I claimed I know Laravel". And its absolute garbage. They haven't used a single Laravel features besides routes and everything else is vanilla PHP. They write for loops that loop through $_REQUEST to remove a single character. Write 100 deep nested ifs and they abuse Elasticsearch to the point ES crashes because the program is using 1000 deep multidimensional arrays. Its only a webshop...

Everytime I try to make a suggestion like making the master branch protected, doing code reviews etc etc I get shut down because they are autistic and don't want anything to change.

Please, stop using `i`, `j` and `k` in loops... specially if they are nested, help the fellow programmer after you

I've worked with few incompetent people till now, but one guy who stands out is my peer who is a "Lead Developer".

First of all he knows nothing!! Even Jon Snow knows something, but this guy knows absolutely nothing. And on top of that he has a hard ass attitude. Never sticks to coding standards, pushes unwanted configuration files to Git, uses too many nested loops even when not even a single one is required.

And when I suggest him something, he starts giving these lame ass reasons and tries to avoid my comments. Then I say, "good luck with that buddy" and move on!!

So i have been learning c++ for more than 2 years now and i the most useful thing that i have ever created is command rine program in Windows that iterates over all the files on a drive and deletes those with a specified extension. So yeah life is pretty bummed up right now.
So i was thinking why not start by contributing to some of the open source projects.
Therefore i went onto github to find something to work with. However the list gontained either projects in languages other than c++ ( i have been trying to learn those) or based on machine learning.
So i thought why not get on devrant and find some people who are willing to work on some projects with me and in the process teach me some stuff. Therefore here i am asking you guys to collaborate with me as i am now sick and tired of making stupid patterns using nested loops.
PS: I am now 18 and in second semester of college pursuing a b.tech in cse

Has anyone else noticed that all arduino code eventually turns into a tower of nested for loops?

Started out with python, while meaning to learn javascript.

I am now competent in python. Im still not sure how it happened.

Started python because I got tired with doing repetative calculations by hand. I think I had like a phobia of problem solving with nested loops. any time I thought a problem would require nesting, especially more than one nested loop, I would just avoid doing it, or end up doing it by hand.

Wrote so many goddamn loops though in the process of exploring graphs, doing things by hand seems like a nuisance. Thinking in loops has its own zen or something.

Now I just need to get over my fear of json-based CLI-enabled configuration-over-convention.

This is probably a standard pattern/algorithm, but I feel pretty good about myself figuring this out.

I was doing a programming challenge and found myself with 2 lists of integer points (x,y). I needed to see where the points converged and identify those locations. Of course I started with a brute force approach and did nested loops to find these locations. This was taking WAY TOO LONG. These lists were 200K each. So checking with naive looping is 200K * 200K operations. Which is a lot.

Then I thought, well I am checking equality, so I will create a third map. The index to the map will be the point, and the data will be an integer. I then go through each list once incrementing the integer for each point that exists in each respective list. Any point with a value greater than 1 is a point convergence.

Like I said, this has got to be a standard thing, so can someone tell me what algorithm this is? I am not sure how to search for this.
I am fuzzy on complexity notation but I think the complexity started at n^2 and was reduced to n. Each list is cycled over once.

People in this discussion will refer to my classmates doing their project we were allowed to choose like 3 months ago and back then I already told them they won't ever manage to make it work in time.

People: "yo could you help real fast"
Me: "aaah not again but okay why not"
People: "here's the code"
Me: "the fuck is this? What is it supposed to do?"
People: "ummm it should doooo eeeerrr... Like this and .... Yeah we don't know. The output should look like that but it doesn't"
Me: "the fuck did you even try to do. That'll never work. And I told you the same thing like 3 months ago when you just chose the project. Just go and use some random math lib you find"
People: "kkkk"

Their code seriously made no sense at all. Parsing substring within like 5 nested loops and like 20vars called "s1" and "theString" and what not.

Too many people seem to think that "goto" in C is the worst thing you could do. It's an abomination, never use it! (Not something I've seen here per se, just generally around)

Challenge:
Break out of a loop inside a loop without using goto, and make it look pretty. Seriously, I don't think it can be done, and goto just makes it so clean!

To the people that mistake i and j in nested loops: Have you considered giving these different names?

Exercise do the pyramid of * and I looked up how to do it but so many people are able to do it without looking it up I dont know why shit to do with nested for loops makes me feel so dumb.

I know it's not a big deal to not know how to do every single thing but I'm always even stuck on the smallest exercises that apparently more people can do than not. Like how am I supposed to have thought about that or figured that out. How am I supposed to learn all this shit. Like for example just look up a list of basic exercises and I cant do any of them. I'm not good at this and its stressing me out because how will I get better or hell even a job if I cant solve these simple problems? How am I supposed to get better at solving these simple problems? I cant just keep looking at the fucking solution because that wont stick or teach me anything

Most stupid thing to rant about by far

Ugh, fuck man. I had planned an extremely general function for printing a truth table for a given proposition for a course, with a little functional programming thrown in. Instead, we are just supposed to show all 2^8 possible truth tables for 3 variables. That's eight nested loops with a hardcoded string that you inject the 8 values in.

I feel so disappointed

I know that when a deadline is present, things like cyclomatic complexity might be something that is a left aside. But I hate so much having to troubleshoot a method with 15 levels deep of nested if, try-catch, loops... Fuck!

Last week I had a meeting to get us all on the same page for today's prep meeting... Tomorrow we have the actual meeting to be followed two hours later by the meeting review meeting... Culminating in decisions that drive the direction of a set of upcoming meetings... Which will all have prep meetings and some have further review meetings...

I'm so excited...

I have no specific story to tell (for now. Will post ke if i remember one) but i have had tons of CS teachers that are shit. From ones who don't know shit to ones who are so bad as a human being i am sure thrte are hundreds of people out there to kill them. I have had multiple teachers where all they did was read out a book and we'd have o site everything they read. Whole fucking semester. And not just one person or once. M-U-L-T-I-P-L-E TIMES AND TEACHERS. then I ve had ones who would rejection my code even if it's better, is right, can andle more edge cases, most likely magnitfrs of times faster and isn an eye sore with just effig if-else on op of if-else nested within if-else with many for loops. Then there are those who want you to do just what they want and expect you to not have a life of your own. Those who blatantly abuse their powers. Those who couldn't care less. Those who are not that bad a teacher but their attitude and style just makes you want to leave. There's one currently who wants a group of 4 people in second year to develop a full blown industry level application in mere 3 weeks. AND WE ARE HAVING OUR THEORY PAPRRS INBETWEEN FOR 2 EFFING WEEKS. So that's just like a month. Fortunately I have a group that's good enough that I can have them do the testing and filling up the documentation​ (did I mention that he needs full documentatiin for software plus a report on how our development process) and have them work on presentation (yup. We need to present this thing) all for just 50 marks. 1 uni credit. Our system still gives 80% weightage to pure theory. Plus the practical part is somewhat theory too.

Our HOD wants us *insists*forces** to stay back at college and work on projects (which is nice but what he ments is use the shitty outdated books from early 2000s to study something). Now I'd be happy to stay back if college provided decent internet (I am not asking for gigabit speeds. Even 1-2Mbps would work) and place to sit. But nope, our college non-teaching staff is eager to send us out of their department and by extention college building. There is literally nowhere you can sit. Plus yup, there is no internet and nowhere for you to plug your laptop in. That's a moot point anyway because they don't want you to use your laptop in college library or anywhere anyways. Plus you don't get much of mobile data too because of the building design. Those work only near windows. Why would I be at college if I can get a 50+Mbps down, area to sit, snacks, port to charge all at home. And you'd say we should talk with him about this – well it's not his issue is all he has to say.

Well, such is life in Indian colleges. And my college/uni is one of the better ones.

MySejahtera is not a good appliaction at all! They just use Sqlite or Shared Preferences in the app for keeping the data local. (Just local?) As soon as you clear cache or data, The user no longer exist! Like wtf ?

So I decompile the app and review the source code, the code is not even properly obfuscated(That's why I can read it). There's a part of the code on a for loop went

```
for (int i = 3; i < array.length(); i++)
{
for (int j = 2; i > array.length() *2; j ++ )
{
onScan();
}
}
```

Which is unacceptable!

First , why nested for loops?

Second, instead of declare 'array.length()' multiple times why not declared it global for once?

No wonder the initial state of the app is buggy as hell.

The Code Abyss Beckons! 🤯

Hey fellow devs, brace yourselves for a wild ride into the chaotic realm of code confessions and debugging dramas! 🎢💻

So, here I am, standing at the precipice of my latest coding adventure, armed with a keyboard and a questionable amount of caffeine. 🚨☕

Today's quest involves unraveling the mysteries of a legacy code that seems to have been written in a language only decipherable by ancient coding sages. 😱📜

As I navigate through the nested loops of confusion and dance with the dragons of runtime errors, I can't help but wonder: Is this what the Matrix feels like for developers? 🕵️‍♂️💊

In the midst of my debugging odyssey, I stumbled upon a comment in the code that simply said, "// Abandon hope, all ye who enter here." 🏴‍☠️📛 Well, isn't that reassuring?

And then there's the moment when you finally fix that elusive bug, and you feel like you've just tamed a mythical creature. 🦄✨ Victory dance, anyone? 💃🕺

But let's not forget the rubber duck sitting on my desk, patiently listening to my monologues about algorithms and existential coding crises. 🦆🗣️

So, dear coding comrades, how's your journey through the code abyss going? Any epic wins or facepalming fails to share? Let the rants flow like a river of improperly closed tags! 🌊🚫

May your semicolons be where they should and your documentation be ever truthful. Happy coding, and may your merge conflicts be swift and painless! 🌈🤞

I had spent all night writing a series of nested loops, my dream was me circling in an old above ground pool like I would as a child. We used to try to make a whirlpool by trying to run along the wall.
