I doubt many people will know who Fravia is, he is one of the finest hackers I am aware of. Note the term 'hacker' here carries no derogatory meaning, in fact it's a compliment.
He wrote a pile of essays in 90's on reverse-engineering. To some idiots he was a cracker who did nothing but wanted to steal software, but his essays convey much more than just cracking and getting software free. His thoughts on freedom of information, how people are zombie-lized by TV, and the view on information have influenced me fundamentally. I have to agree it was his prowess that I really look up to and eventually driven me to engineering
I learned that he passed away on May 3, 2009 and he left a final page on his webpage here.
