The 2012 edition of the Linux Plumbers Conference concluded recently. I was there, running the virtualization microconference. The format of LPC sessions is to have discussions around current as well as future projects. The key words are ‘discussion’ (not talks — slides are optional!) and ‘current’ and ‘future’ projects — not discussing work that’s already done; rather discussing unsolved problems or new ideas. LPC is a great platform for getting people involved in various subsystems across the entire OS stack in one place, so any sticky problems tend to get resolved by discussing issues face-to-face.
