Discovered pro tip of my life :
Never trust your code

Achievements unlocked :
Successfully running C++ GPU accelerated offscreen rendering engine with texture loading code having faulty validation bug over a year on production for more than 1.5M daily Android active users without any issues.

History : Recently I was writing a new rendering engineering that uses our GPU pipeline engine.. and our prototype android app benchmark test always fails with black rendering frame detection assertion.

Practice:
Spend more than a month to debug a GPU pipeline system based on directed acyclic graph based rendering algorithm.

New abilities added :
Able to debug OpenGL ES code on Android using print statement placed in source code using binary search.

But why?
I was aware of the issue over a month and just ignored it thinking it's a driver bug in my android device.. but when the api was used by one of Android dev, he reported the same issue. In the same day at night 2:59AM ....

Satan came to me and told me that " ok listen man, here is what I am gonna do with you today, your new code will be going production in a week, and the renderer will give you just one black frame after random time, and after today 3AM, your code will not show GL Errors if you debug or trace. Buhahahaha ahhaha haahha..... Puffff"

And he was gone..
Thanks satan for not killing me.. I will not trust stable production code anymore enevn though every line is documented and peer reviewed.

I have a guy sitting next to me in class. We were working on the same project. It's about rewriting a functioning mergesort algorithm in C and doing a presentation about that topic.

Now... the thing is that I was ill on that specific day when we got that project assigned. And he didn't tell me it either. I asked the whole class.
They just said that there was nothing special about that day. These fuckers.

Anyway...
Thé following week we had the same lesson again. Actually there were more than both of us. We were a group of 5 dudes.
3 of them barely have anything to do with programming at all. They just learn for the exams and have bad grades in programming.

Luckily, they already wrote the functioning sorting algorithm.
Since that is the case, I chose to review it to get deeper into that topic.

There were comments in English (we live in Germany) and these comments were written in a different style. My classmates would never comment in such a way.
It was a modified version copied from the internet. The whole source code.
The variables had names like j,k,b,u and so on. It was perfectly obfuscated.

Yesterday, I wasn't at college either.
I had to show up to a given time at a government bureau. They have been working on that project that day. So, I decided to ask them via a messenger, if they can give me the newest presentation files after 1 pm.

They said that they barely have anything to present. They would like to improvise they said.

"Fuck you all" I thought.
I'm done with these fucking illiterate humans.
I hope they all die in hell with satan having a ride on them. Stabbing them from behind right into their assholes and eating their ball sacks (if they have any).

Today is the presentation.
That's when I decided not to drive there during these specific lessons.

Oh man, I found the names for the different number bases past 36! I should expand my base converter!

That doesn’t... look right...

Ah, because these ones require the use of encoding algorithms.

NOPE NOPE NOPE NOPE

Planned release today, one of my co-worker's laptop's hard drive died in the morning.

And you guys say Satan is not real :/

So I got my sister a new PC and being the thrifty (and masochistic) fuck I am, I thought I'd build it myself. I built the PC yesterday (side note: Stick to backplate coolers, Push-Pin is the bane of my existence, patience and fingers) and wanted to install Windows today.
I shit you not, I ran this godforsaken spawn of Satan of 'Windows Media Creator Tool' no less than 5 times with different USB sticks, different Ports, turned off AV and FW and as Administrator but stuff ain't working. After ~30min of downloading Windows each time, it always told me in usual Windows manner "Something went wrong", because who needs decent error messages anyway...
