I develop an obsession about something very easily. I usually use a GNU/Linux distribution named Trisquel, which is entirely free as in freedom. I have a cat, from which my HackyCat username comes. I also am an "hacker", which means I do modifications to items. :P
So, about my hobbies... Well, I usually read about free software, read some activist newspaper (notably Anonymous newspaper), pet my cat, try to learn C++ and Python and try to get new project that I usually never finish.
