Right now am listening to a talk about the story of the founding of BSD, and the invention/discovery of "strangers will send you patches", and the development of the contributor, captain, integrator system. And then a description of how to deal with a contributor community.
The previous talk was by Eric Allman about running a company and dealing with investors vs founders.
Before that was by someone from INGRES about "Myths of Open Source".
I missed BrianB's talk, because figuring out how to park here at UC Berkeley took too long.
