In my college days i was designing a bootloader for avr microcontroller , i had the idea to flash code wirelessly to avr over bluetooth and also cross compile the compiler for android device so that you can code on android, every thing went well just one thing didn't, i saw that code of certain size is executing properly , greater than that size gives me wired outputs so i have to dump hex from the avr (that is flashed the by bootloader) and compaire it with the original hex of code it got messy as you can see, most fun part of this bug is that error can be anywhere cross compiler may be fucked up , the bootloader may be fucked up , or it may be my bluetooth module , after 14 hours of staring at the hex code i figured out the mess in bootloader instruction that was changing the page address for flashing .
when it worked it was 3am in night i literally burst into tears of joy next day bought myself a cake to celebrate6 -
Do you ever feel like a mad scientist when you are just sitting there in front of your computer, it is 3am and your code finally compiles?1

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. -

That moment when you're so engrossed in your project that you lose track of time. You begin to SEE code irl, not just on screens. Things like hunger, environment and a sense of time fade away. That feeling when the code just works, but better when it doesn't and you figure out a smart fix. Oh gosh ill pay to feel like that all day.
I wrote a shitty layout for an android side project. It haunted me. I could still SEE the shitty xml long after the pc was shut down. I had a nightmare about it and woke up sweating, and all I could see was xml. Fkin xml man. I redid the layout at 3am and boy was i so satisfied.
I think that was just the tetrix effect taking its toll on me.
I always got screwed by parents for being on that machine all day, back in school. But none of that matters now. I can now feel the code running in my veins and flowing into the machine. I can now feel my heart throbbing at the sight of such beauty. They ask how i manage my social life. I say everything goes well until i start a side project, that's when social life gets fucked hard. I think I'm gonna die one day after performing the final commit.5 -
Had to make a change in an ugly codebase. For this I had to change a config value which was duplicated three times in the code base. So I wanted to refactor the code so that the config was in one place.
I worked on this for two days and it was starting to look good. On the third day when I started to work on this I realized that I couldn't start the server anymore. Looking through version control I figure out that my co-worker had stayed till 3am last night to work on the change I was supposed to make.
I had to spend all morning undoing his commits. Once I was done refactoring the actual change took me ten minutes.
Why the fuck would you stay until the middle of the night to work on someone else's task?!
Could have just asked how it was coming along if I wasn't working fast enough for him.2
