Velocity NY is Coming!

O'Reilly's Velocity Conference is quickly approaching -- it's September 15-17 in beautiful New York. As a follow up to last month's post, I wanted to make sure people knew I had 3 more tickets left to give away to this epic front-end performance conference!
In my last post, I asked for links to awesome performance-related articles. I learned a ton and I hope you did too! This time I'm looking for something a bit more interactive!
