unix.. unix.. unix.. Beside my eternal love for the kernel, I spent my time wondering in old cities, places, and enjoy very much archeology, history, old castle, sociology, theology and psychology. Beside my passion for Linux, I spend my free time, providing support and writing code for the Open Source Community... I have developed a few apps, API codes and wrote few articles... Beside all, I am also a book worm, a wannabee photograph (well i try :p), a random imaginative cook and a very intuitive, sociable person :) and oh yes! I play the drums :)
