I've just submitted my proposed OSCON talks to the BBC who will, in turn, submit them to OSCON. In doing that, if either is accepted, the BBC will pick up the travel tab for me.
If you are going to OSCON or would go if you could, would either of the following two talks interest you?
The traits talk is long overdue and far more important, but I need to think of a way to spice it up better and make it more accessible. It's for advanced programmers, but the concept itself is dirt-simple once it "clicks".
