Carl and I talked about cairo code and community. The slides are now available here.
In the spirit of cairo talks for the past five years we wrote our own presentation tool. We wanted to be able to be able to have arbitrary cairo drawing in the slides without having to make SVG/PNG out of them first, so we spent 24 hours writing the tool in PyGTK and the final hour before the talk to populate the slides. Anyway, the code is available as a git tree here, or just browse it here. I think it's pretty cool and I'll be polishing and using it for other talks in the future.
One interesting aspect of writing the above tool is that Carl and I totally understood what people mean when they say cairo is slow. Got a lot to do. Stay tuned...
