• Formal Methods, Verification and Some Computing History: Interview with Wolfram Schulte at ICSE 2011 for Microsoft Channel 9. I was sitting too close to the camera (I won't make that mistake again), so I present a rather disturbing image of bulging teeth and eyes. You can avoid distress by just listening to the sound track: here's a direct link to the mp3 audio
• After Dinner Speech at the Marktoberdorf Summer School, August 2010. This was recorded by one of the students. I weave parodies of the other lectures into an account of an interesting aviation incident (see this also), but I'm afraid the jokes might not work if you hadn't heard those lectures. I guess you had to be there.
