I had a great time at QCon New York last week. It was my first time there and my first time speaking too. The audience was engaged and had great questions. I did a book-signing at the Pearson booth and it was fun meeting readers (and future readers) of our books.
Videos of all talks will be available soon. For now you can view the slides. You should also check out the talk by David Fullerton, VP of Engineering of Stack Exchange (my boss's boss) who gave a great talk titled "Scaling Stack Overflow: Keeping it Vertical by Obsessing Over Performance"
Hope to see you next year!
