UNIX is basically a simple operating system, but you have to be a genius to understand the simplicity
I use GNU/Linux Debian as operating system for my PC's.
I use Debian because it covers all my needs, and gives me the functionality I want to have over an operating system. It let's me modify it and build it from the scratch. But the thing I really love about Debian is it's social contract.
I decided to maintain a blog about Debian and Linux in general.It has over 120 posts with useful tips, tutorials, recommendations and reviews.
