The other day, I saw a "person" with a gibberish name posting stuff in shout chat...except it was a bunch of garbage characters. Eventually, out of curiosity, I pasted the chat message into a hex editor.

It was that garbage filler that's used on unallocated memory. Compiler and OS programmers often make it so that when reserved memory is no longer reserved, it's filled automatically with recognizable junk for debugging purposes. Stuff like 0xDEADBEEF.

I haven't laughed that hard in awhile. I guess I really am a nerd.
