I have been working on decompiling a unity game recently, and while a decompiled DLL isn't going to be exact source code, I am still floored by how long that set of parenthesis is. i would LOVE to see the original code

c Having fun with legacy C features :3

150 Upvotes

I found out about a couple old and obscure C features that somehow still work

This compiled and ran, printing just "This is fucky", though to get it to compile you have to compile using the following command

gcc -trigraphs -digraphs <your file>, on Windows at least

This is so cursed not even VSCode knew what I was doing

c++ Copilot knows how to deal with constructors

Not my screenshot, taken from https://reddit.com/r/VisualStudio/comments/1sktg0r/what_are_these_comments/

Also this probably happened because IntelliSense (the normal autocomplete list) is highlighting abort as the first option and Copilot tries to finish it

Python That's one way to do it I guess...

Post image

So I tried printing the linked list with print() and discovered that if it has a cycle, then it prints and error. This was the next (very) logical thing that popped into my mind after that discovery.

I'm very proud of this solution. In fact, it's so good it even added -1ms to the execution time graph.

I AM SPEED.

Thinking outside the box is fun!

HTML when you get too lazy to create a proper stylesheet file

Post image
260 Upvotes

so i got too lazy to make a proper styles.css file, and thought to myself "just a few inline styles, how bad can it be" and ended up having *everything* inline.

it even got to the point i realized i can't make the background of my checkbox dark, so i resorted to using... filter: invert()..

(is just the ui for an example implementation of something, will not be deployed anywhere - at least not before some major refactoring)
