Work Rant, again.

Working on a project, it has a messages feature.
Currently it supports text messages and images.

The guy before me had to leave, so I was put in charge on this project, to develop it.. all alone...

Project Manager : "Please add PDF support to messages"

Me : "Sure its an easy task".

1 day later:
-Starts working on that feature
-PDF files can now be sent.
-Looks at the sent messages-
-Message is there but I... I cant see the PDF file-

Hmmmm...
Moments later I discover the entire system is non-modular... hard-coded images only support.
Fuck me.

Real Linux fuck up coming up.

Be me.
Working on a project.

Accidentally used sudo with git pull, every file now is only accessible for root users.

Thinking to myself.. okay I'll just do chmod 777 to the current directory

Forgot how to use chmod
At first something like
Sudo chmod ./ 777

Not working
Maybe
Sudo chmod / 777

Not working
Remembering that it's the other way around

sudo chmod 777 /

Now... I fucked up. I forgot the dot, and for a sec I forgot that '/' means root directory and not current like './' does.

Few moments later the permission system of Ubuntu is utterly fucked. Everything is not working.

Need sudo in order to fix everything but sudo isn't working.

Few hours of crying later,I solved it thanks to some nice ppl online helping stupid people like me who used that command...😂

-Writes an algorithm that randomly generates a dungeon for my RPG game I'm writing in C++ with SFML library-

after 6hours of reading papers about algorithms, writing an algorithm myself, at 4 am I decided to give up and re try tomorrow and fix all of the problems, but all that I had in mind is, what the fuck did i just write here.. I'm sure the next day me will not understand what the hell is going on-

Work rant :

I once had a code review and remembered I forgot to comment my code and said sorry I forgot to comment it out.

The reply I got?
Don't worry, here we say your code should be readable enough and no comments are required.

Im still amazed, like... Even if the code is readable, fuck this I need a tl;Dr comment for the long ass fucking code... What the fuck

Work story.
We have this system that's being used nation-wide and basically there's a control panel for management (it's a website)) and an app for the regular users.

I just migrated and replaced the guy before me, I'm basically the only one on the project.

The code for the website is a mess, the servers are sometimes slow, and few security problems here and there.

Project Lead comes up to me and says that few of our clients that use the website are saying it works really slowly.
I start by analyzing the networking, and found shocking things.
First of all, let's say there's a messaging option, and the management teams that are our clients can have each a lot of groups, which all have messaging.

Upon first load, ALL OF THE IMAGES, FROM ALL GROUPS, ARE PRE LOADED. It can get up to few hundred photos being preloaded upon first load, which can explain the slow loading.
After discovering that, I discovered that the Administration control panel, which only my project lead can access, with sends heavy requests to the server and loads heavy assets, is loaded every time to every single client, generating heavy stress on our server and slowing everything down.

I tell that to my project lead and say that that's what causing the slow downs, I coded a fix that currently sits and is not being merged to the master branch to be deployed, and somehow I need to find a way to fix the slowness which all comes down to the heavy requests and slow connection with servers... And they won't merge my fix that fixes the loading of the administration panel so the stress on the servers could go down, and everything will be sped up....
Ah damnit.. sometimes I don't understand it..
