Paolo began programming at the age of 9 with a glorious 8086 and GW-BASIC, then he played a bit with C, ASM and Pascal. He tought himself MFC and Windows programming, to exploit his studies of C++. Always attracted by low-level programming and Assembly, he's beginning to appreciate the joys of templates and STL. At work he changed his mind about Java, discovered Eclipse IDE, and now think it's cool.
He lives in Follonica, Italy.
He has been abroad in the U.S. to work on his final thesis before graduating. For seven months he was playing with airplanes and automatic control at the Unversity of Illinois at Urbana-Champaign.
He graduated in Computer Science Engineering at the University of Pisa, Italy, in December 2003.
