Here are links to some of the talks/presentations/etc I've given. There's a page for each talk with links to slides, video and/or audio. More recent talks are listed first.
This isn't currently a complete archive, but if there's a particular talk you'd like to get hold of slides for, feel free to prod me with as many details as you can remember about the talk, and I'll see if I can locate the slides. I'd also love to hear if you know about slides, video, audio, etc out there on the web which aren't linked.
