My wife went to do some work for a charity. They "got her the best computer available". It was a poor mangled MacBook whose better days were somewhere in the dawn of the last decade.
She tries to type anything... and only gibberish appears on screen.

She comes to me, absolutely me puzzled. I try to type anything... gibberish. I boot up in safe mode, everything is OK.

I look around for system configs... there is a custom keyboard mapping enabled by default.
We check the weird stains on the keyboard... they are regular and in all keys. Like if there used to be adhesive stickers on the keys, and those stickers were later removed.

I boot up again... and type "q". It becomes "a". I type "w". It becomes "b". I dread typing "e". Sure as bug, it becomes "c".
By the love of byte, someone asked for a custom keyboard layout... IN FUCKING ALPHABETICAL ORDER.

It was easy enough to change the layout after that, but the weirdness continues: my wife asked around, and apparently the laptop used to belong to some old dude... who was convinced there were characters missing from his keyboard. Apparently he could never find them in a regular QWERTY layout.

I wish I could give some encouraging words for the kid who came up with the solution. Working around technophobes is a drying art, that needs to be rewarded.

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 :)

I think we should have nicknames for people who never went to school for coding/developing, here are some names I'm thinking:
"Analog Junkies"
"Tech Illiterates"
"Manual Laborers"
"Tech Relics"
"Old-School Luddites"
"Digital Dunces"
"Technophobes"
"Non-Techies"
"Primitive Users"
Let me know if you have any other ideas
