FOSDEM is the Free and Open Source Developers European Meeting, which has been held at the ULB in Brussels for the past few years. This year’s event is on the weekend of the 26th/27th of February. Since the beginning, the EU Mozilla group has had a developers’ room, where we have our own track of Mozilla-related talks and discussions, and there will be one this year too. A schedule is under development.
I’d encourage all European free software hackers, and particularly Mozilla developers to make an effort to come.
