First Post

This blog started today because a friend asked "what is /dev/null ?".

So, why start a blog after that question? First of all, there is so much "garbage" information on the Web nowadays. Information that should be redirected to the null device :-P

Secondly, I've started talking with Pedro Gomes about the idea of create a blog with useful geek information. Like useful hacks, informational stuff, programming stuff, etc.

Besides sharing useful information with the world, it is a good repository!

Oh, btw /dev/null it's a virtual file of Unix-like operating systems. This special file discards all the information written to it but can be used for reporting successful writing of data.

It can be used to redirect the unwanted output of a program to it. It's called the black hole in computer jargon.

Psst, if you log in a machine and you don't want that your commands are logged, just redirect .bash_history to the black hole ;-)
