You have a lot of questions in a single post and there doesn't seem to be anything wrong with your code, which is out of the scope of SO. Your question might be more suitable at codereview.stackexchange. — Emiel Zuurbier 52 secs ago

I would start with the Learning Perl book. That's the best beginner resource. OP's company should be willing to pay for that if money is an issue. Gabor's perlmaven.com is a very good free resource, although it's not really a class. SO is of course good, and I would also look at Code Review. Post some finished code there and we'll give you constructive feedback. There are also Facebook groups for help, and of course perlmonks. perl-community.de is a German language message board that is quite helpful, too. — simbabque 25 secs ago

Seems like your teacher is a bit frustrated and out of shape if apart from that comment he did not give you any clues. Raw pointers are OK, as long as the ownership is clearly defined. To make it easier, just use unique_ptr and shared_ptr (but careful with that if you have cyclic dependencies). Anyway, there are many other things that might be improved in the code, go for codereview as suggested. — pptaszni 26 secs ago

It ensures that the source code is formatted uniformly across all the codebase, thus saving time during code reviews and eliminating a potential source of tension due to different code style preferences among team members. It also reduces cognitive load when writing the code: often it's very convenient not to indent a piece of code too precisely, knowing that the formatter will take care of that as soon as I build the project. — Vadim Belyaev 43 secs ago

I like to have interfaces hiding implementation details and usually start with one or more basic interfaces. Exposing raw structs leads to coupling the internal representation with what you give your users, making it impossible to change the implementation without breaking the users. I realise this goes against your second link, which seems the default for Go, but it does say "generaly", not "always". Accessing external dependencies would make a valid exception for that in mind mind, but I might be missing something from that codereview link. — pedromss 51 secs ago
DoSomethingAPIClient seems fine to me, but possibly just have 1 method as that's all the users seem to care about. Yes, it goes "agaisnt" the codereview link, but I consider those guidelines, not rules. Just a thought, don't think you'll really find a correct answer here, seems very subjective. — pedromss 50 secs ago

@Jimmy You may very well like the answer. Many beginners want to do something like that. But doing it it is nearly always unnecessary. It is also brittle, hard to maintain, and a potent source of bugs. The advice from the duplicate was to use a dictionary or a list. That is good advice. I know you can't see why this is a duplicate question: it's because it tells you your approach is wrong. But if you present this sort of thing to a code review, you may find your colleagues unsympathetic. — BoarGules 14 secs ago

multiprocessing or multithreading won't make things better there:there are lots of things to improve in this script before thinking about that. And even when it is fixed, it may be that parallelising this brings no further improvements. Maybe you'd be better posting this on codereview.stackexchange.com , another site on stackoverflow's network, since this requires a major rewrite, with several points where one can teach you interesting stuff. — jsbueno 12 secs ago

@CaptainObvious Great diagram, no code!
 
@Duga rolled back
@pacmaninbw the one answer contains "... and I am assuming that your input is also an indexed array of indexed arrays" so that could be updated, and mick might likely do that soon after coming online... the OP notified mick in a comment
 
OK, my bad I guess.
 
I'll keep an eye on it
Thank you very much, some concepts I didn't even knew, like transposition. I've updated the question with a input example if you want to write more. — denies 32 mins ago

@pacmaninbw That's not runtime code - it's an analysis tool to help you choose scaling values and frequencies.
 
@Reinderien Okay, I didn't have a choice in the scaling this time. Any suggestions on how to get the time to as close to 1 second as possible? That's how long the LEDs are supposed to be lit before the toggle. It isn't even close to 1 second now.

Welcome to Stack Overflow. Please read How to Ask, try to identify one specific problem, and then ask a question about it. "Any ideas on what to improve" is out of scope here; we want don't want questions to be subjective (try Code Review for code review) or too open-ended. "it seems there are a few problems with insert and delete method" isn't helpful; what are those problems? How do you test the code? What is supposed to happen when you do that, what actually happens instead, and how is that different? — Karl Knechtel 13 secs ago
