This was during my 3rd semester when I was outside my dorm room finishing my Java assignment. Suddenly this kitty jumped from nowhere and sat near my laptop seeing those buggy Java codes. Then I started to pet him as he sat on my keypad. After this incident, he came outside my dorm room every other night waiting for me to pet him. He was one good friend that I got during that semester. I really miss him now.

What if a code, running a factory, making dev ducks, was buggy? Would these ducks cause more bugs in our codes?

Is it OK to punch a game dev who codes stupid numeric bugs?

So my wife got into Stardew Valley, that admittedly awesome comfort game farming simulator.
She went pretty far in the game, and found some item that was supposed to highly increase the damage she could inflict onto cute little monster thingies.
It didn't work as intended.
Since equipping the piece of shit all her hits did 0 damage. She tossed the item away but the problem persisted. And on and on...
She took to the googles to try and find some explanation, and apparently that is a fairly common bug for mobile devs.
Then she called in the big guns (that is how I'm calling myself in this case, you will see why).

Apparently there is some buggy piece of shitcode somewhere in the game with a numerical insecure routine that overflows the attack modifier. I.e. if it was supposed to increase from 1.990 to 2.010, it actually went all the way down to -0.4.
She was lucky her attacks weren't increasing the monsters' HP.

We found a forum post where some dude said that he managed to edit the game save file and reset the negative-value attack increase modifier variable. Seems easy enough at first, but my wife uses iOS. Nothing is ever so straightforward with apple stuff.

We did get to the save file, she emailed it to me (the file has no extension and no line breaks in it, so we facepalm'd on a couple attempts at editing it directly).
I finally manage to get it into my personal 11-yo laptop... that won't open a single line file that big.

Cue the python terminal. Easy enough to read the file into a string var and search for the buggy XML tag. Edit the value and overwrite into a new file. Send it back to her by email. Figure out how to overwrite the file in iOS.

Some tense moments while the game reloads... and it works!!!! Got some serious hubby goodwill points here.
Srsly, this troubleshoot process is not for technophobes. It is out of reach to pretty much every non-techy user.

And now back to the original question: If I ever manage to find the kid who coded a game-breaking numerically unsafe routine and shipped it as if every test in the planet had waved it bye-bye, can I punch them? Or maybe buy them a beer, let's see how I get to cash that hubby goodwill tonight :)

What are your best practices for debugging buggy codes?
