After reading a lot about interesting stuff happening at this years FOSDEM, I decided very short term to go there. The FOSDEM in Brussels is probably one of the biggest (if not the biggest at all) meetings of free software developers. Unlike similar events (like several Linuxtag-events in Germany), it's focus is mainly on developers, so the talks are more high level.
My impressions from FOSDEM so far: There are much more people compared when I was here a few years ago, so it seems the number of free software developers is inceasing (which is great). The interest focus seems to be to extend free software to other areas. Embedded devices, the BIOS, open hardware (lot's of interest in 3D-printers).
Yesterday morning, there was a quite interesting talk by Richard Clayton about Phishing, Scam etc. with lots of statistics and info about the supposed business models behind it. Afterwards I had a nice chat with some developers from OpenInkpot. There was a big interest in the Coreboot-talk, so I (and many others) just didn't get in because it was full.
Later Gentoo-developer Petteri Räty gave a talk about "How to be a good upstream" and I'd suggest every free software developer to have a look on that (I'll put the link here later).
I've just attended a rather interesting talk about 3D-printers like RepRap and MakerBot.
