Full audio/video recordings of the conference for the 2005 Drupal Conference (@ FOSDEM, Feb 26, 2005) are now available.

Also, there are some more notes floating around:

• Availability, Scalability, and Security of Drupal – interesting benchmarks on MySQL local socket vs remote access perf
• Theme Development presentation
• Content Construction Kit
