He talks about the location of the meeting (a pub named "The Hope") and some of the notes about his talk. The talk was a modified version of his Test Driven Development talk (given previously at php|tek). He changed it to appeal to people who hadn't really used unit testing in their development to explain why it's important. He includes the bit of sample code he used to illustrate his point - a test designed to ensure that the daily salary was being calculated properly. The presentation can be downloaded here as a PowerPoint file.
