As a Nifty Guest, I gave a total of 3 presentations at Penguicon:
- Transitions in a free / open source software project
- Building community in a free / open source software project
- Linux in the enterprise
Each talk was well-attended. If you'd like to see the slides, click the links above. I'll warn you now, though: many of the slides are very "conceptual", so you may not be able to make sense of them without hearing me talk about them.
