Subject: Linux + bash and a silver fork

Well, as has been said when you realize the truth that there is no spoon,
but instead there'll be a
bunch of forks instead, at least in linux on bash shell, tested ubuntu and
RHEL this far.

By throwing a nice piece of line code as a command in bash shell (normal
user) you can pretty much
crash the whole server cause denial of service by giving a command in bash:

:() { :&:; } ;:

Almost as the ascii would be smiling..
