Of course I’m a bit biased because I couldn’t attend other tracks as I was chairing the “Development” track at LSM/RMLL, and because I “selected” the speakers.
I’m really glad to have welcome so many interesting presentations on development questions in libre software projects (or with libre software).
There are much too many interesting bits to mention, and I’m still recovering from the holidays after the conference, but you’ll already find most of the slides attached to the articles (french versions) linked from : http://2009.rmll.info/-Developpement-.html
Some videos will follow sooner or later.
Enjoy !
