At TechEd this year, I gave what can only be described as an overly ambitious talk given I only had 45 minutes:
Coding4Fun: The Secrets to Programming YouTube, iTunes, Microsoft Zune, Windows Vista Peer-to-Peer APIs, and Even World of Warcraft
I say overly ambitious as YouTube, Vista P2P, and Warcraft could easily have been dedicated 75 minute sessions so covering all of them enough to be meaningful in 45 minutes was....a challenge. As promised, here's a quick recap of my slides and code. The full slide deck can be found here, and thanks everyone for showing up!
