If you haven’t seen this site, you should check it out. TED.com is a site containing presentations and information from the TED conferences (Technology, Entertainment, Design). The top representatives from a variety of fields present short (usually less than 20 minutes) talks about their area of expertise. There is a lot of good stuff there. Every talk I have listened to has been excellent, but a couple of my favorites are Why People Believe Strange Things by Michael Shermer and 18 minutes With an Agile Mind by Clifford Stoll.
These talks aren’t specifically database related, but understanding the world and the way people think is important when thinking about how to design anything, including database software and database applications.
