Linux is an efficient and reliable Operating System based on the UNIX engine. Its source files are entirely free and everyone can modify and tune them in order to build up the most efficient system for his own computer.
I began my adventure in Linux in the 1997, and then I went on discovering the power, usability and reliability of this new World all by myself. Year by year I've truly accepted the philosophy and I wrote some How-tos to help newbies and other people get accustomed and feel at home with the penguin.
I use Slackware and Arch, as they are the most coherent to the original UNIX.
This leads to no graphical-help, but just deep understanding of how tools work in order to take the most out of them through editing manually the configs.
As someone once said: "When you know Slackware, you know Linux...when you know Ubuntu, all you know is Ubuntu".
