On the GSoC mentor list I found:
1 - 2, February, 2014 -- Brussels, Belgium We are very excited to have a table dedicated to GSoC at FOSDEM 2014 at the Université libre de Bruxelles, Campus du Solbosch.
FOSDEM is a free event where you can mingle with 5,000+ of your closest FOSS friends. If you would like to demo/talk about your project in our table at FOSDEM please fill out this form. As space permits we will assign you a 20-30 minutes time slot so you can tell other attendees about your project and experience with GSoC, including a demo if you’d like to. We will send you a confirmation with your assigned time slot by 26 January.
