Which European conference is the best equivalent of OSCON?

Question

Looking for a large European developer/software conference, open-source-friendly, programming-language-neutral, platform-neutral, vendor-neutral. Any recommendations?

• apparently there briefly used to be a Euro OSCON (2004-2006? what happened?)
• some good language/app-specific ones like EuroPython, EuroSciPy, DjangoCon
• European BarCamps seem kind of fragmented, esp. for an English-speaking audience
• anything bigger or better? If there isn't anything, I wonder if O'Reilly would resurrect Euro OSCON.

Answer 1

Living in Belgium, I would suggest FOSDEM. Can't compare to other conventions though.

Answer 2

I heard a lot about OggCamp on the Linux Outlaws Podcast.. sounds like it was pretty good, but then I don't know much about OSCON.
