"Convinced" me to quit a shit job. Does that count?

Walked into the office in the afternoon, everyone was kinda panicking
Asked what was going on, well, the ticket system is not working anymore, can't put in any new tickets.
So I started to look for the issue as well, checked the system and... The last tickets' IDs were at ~32k. Ha. Looked into the source code and, sure enough, they used a data type with an upper limit of... 32k. So when trying to get a new ticket ID it just crashed and burned.
Quickly changed the data type and stopped the office panic in around half an hour.
Memorable not because of how tough the bug was, but because of the impact and the simplicity of the fix

Helped a friend who's currently learning programming in Java
Looked at the slides used to teach them and apparently the teacher explains the "static" keyword as "can be accessed from any function of the class"... Which... Isn't at all what static does
At that point they hadn't started with actual OOP stuff, so I kind of get why they didn't explain what it really does, but why the fuck did they just put down a completely wrong definition?! Instead of just saying "yeah you'll just need that keyword for now, I'll explain it later"

Hiring a third party to help us with something...
Third party: yeah okay, we know what we need. Can we get access to your git repo
Me: sure, I'll make sure you'll get it
(To the admins): hey can you get them access to our git server?
Admins: did they sign the personal data processing contract?
Me: oh they won't work with any personal data. It's a dev server and they only need access to the source code. And the usual contracts and NDAs are already done
Admins: well we still need the other one.

... Sure. Why not. Just delays the start of the process for... Like a week and a half until that useless bit of paper has passed through all the necessary departments. Not like time's an issue. Right?

Was fixing a bug and suddenly got an error that the lodash library could not be loaded. Funny, didn't even know the project used that lib. Looked for the reference and the previous dev used _.times instead of a for loop. Ha okay, interesting. Wonder where else this library is used.
Searched the whole project for references, dependencies, whatever, any sign of it. Fucking. Nothing.
Rewrote the _.times part as a simple for loop, then removed the library. The rest of the project still worked perfectly. Took me about a minute and a half.
Who the fuck uses an entire damn library to... Not write a for loop I guess?!

So, first time ranting, sorry if I mess anything up.
When I first started my current job and got introduced to the system we were coding in, something seemed a little fishy to me. Didn't like the system anyway, but at least the language is a compiler language, so it runs quite quickly, right?
In theory, yeah. If the lead dev liked the IDE that came with it. But he has to REALLY fucking hate it, because rather than using it, he codes in plaintext. No syntax highlighting, no auto-indent, nothing. And he's built the entire damn system around doing that. Sadly the compiler is only integrated into the IDE, so what do we do there? Copy the code from the plaintext file to the IDE to compile it there? No no, why would you. The language has a function you can use to compile some code at runtime.
And so he does. Every. Single. Fucking. Script. There's a single main script that runs and finds the correct textfile to then runtime-compile and execute. So we effectively made a compiler language into a massively unoptimized interpreter lang.
I even mentioned that this might be a problem, but I was completely dismissed, so at that point it's not my problem anymore and I have then switched to a different system anyway.
Couple weeks later I heard the same guy complaining that the scripts were running almost the whole night so we'd probably need some better hardware or something.
Well if only there was a really obvious solution that would improve the performance by probably about a factor of 20 or so...
