In September 2010 I gave a talk about Aspect-Oriented Programming at the WebExpo Conference in Prague. The session covered AOP in general as well as its actual use in combination with FLOW3. Although it's been some time ago that it was recorded, I wanted to share the video the WebExpo team took during the conference.
Unfortunately there was no microphone for that particular session but certainly you'll understand the most important parts anyway (you might want to use headphones if you're at a crowded place). Enjoy!
