Just thought I would pass on details of this event. Its a free event in Brussels and has lectures coving security.
"FOSDEM (Free and Open Source Development European Meeting) is a
European event centered around Free and Open Source software
development. It is aimed at developers and all interested in the Free
and Open Source news in the world. Its goals are to enable developers
to meet and to promote the awareness and use of free and open source
software.
It takes place every year in February at the Université Libre de
Bruxelles (ULB), situated in the southeast of Brussels, and easily
reachable by public transport from the central station."
