A quote by jwz, from the Unix haters handbook.

Linux works well, if you understand how it works. If you don't understand how it works, you have to hit the documentation until you do. If you want to do something complex, you can read the documentation for a really long time before you can do something you thought ought to be simple (like configuring PPP, for example).

A great way to burn your weekends, if you're a geek.
