In June of last year Linus Torvalds held a Q&A session at the Aalto Center for Entrepreneurship. It's a far reaching and interesting talk. Torvalds talks about tool building, the beginning of Linux, how the project is run, why Linux has conquered every domain except the desktop, and many other topics.
Torvalds is an interesting guy and famously blunt in his assessments of people and things. This is the video where Torvalds gives his famous characterization of NVidia as the worst hardware company in the history of Linux. It's at about the 50 minutes point if you can't wait.
The video is about an hour and four minutes so plan accordingly. It's long but worth your time. I found it fascinating.
