If you are an open source developer and want to share your insights then Foss Camp is the place to be Friday and Saturday - Dec 5 and 6. It will be held at Google's Crittenden Lane Campus.
Based on O'Reilly's invitation only FooCamp (Web Link) where the agenda is made up at the start of the conference, login at Web Link.
Folk want to talk about systems administration, mobile, Ubuntu servers, CinePaint and more. Ubuntu is Linux with apps and is a serious competitor to Microsoft Windows, with Office (use Open Office), Adobe Photoshop (use Gimp) and more.
It should be lots of fun.
