I'm a free software enthusiast, and have been using GNU/Linux since Debian 2.2 "potato" (2000). I started contributing back to Debian in early 2007, and I finally became Debian Developer on November 08, 2009.
I'm also an OpenStreetMap contributor. I mapped almost all my city (Mazara del Vallo), and the most part of the Province of Trapani. I also mapped random areas around Sicily. All this using a Transystem iBlue 747-A+. If you need a GPS datalogger, get it. It's not expensive although being fairly accurate. Since the end of 2011, I also use a Samsung Galaxy Mini and its integrated GPS unit.
If you need to contact me, you can send an e-mail (you'll find it at this page), or you can find me on IRC (OFTC/Freenode) as hanska or dapal.
I'm available for GPG keysigning. I'm usually in Mazara del Vallo, but I also travel a lot due to my work, but usually always in the western side of Sicily. Just contact me to know where I am. In any case, here are my GPG keys, 0x1392B174 and 0x79467018. One day or the other I'll completely move to the latter key, since it's more secure.
