In university we were taught C programming. We started with simple things like loops and stuff. After a while the topic processes, threads & stuff came up and of course we were instructed to use that.

In the computer lab there where only thin clients so everything actually ran on the server.

A good friend of mine - not know what was about to happen - entered:

while (true) {
    fork();
}

Astoundingly it took a whole minute until the server froze. 🤣
That was the same server most of the school stuff ran on. So nearly everything went down. 😂
He got scolded by the sysadmin the next day but nothing serious happened.

I'd scold the sysadmin instead for not cofiguring critical systems in a secure way. Ulimit exists for a reason.

What does that command do?

Creates a new process. So, it would create an infinite amount of processes filling RAM.
