Scaling is a perennial problem. One day you are happily serving 10,000 users and suddenly that pesky CNN picks you on you and you have to deal with a million users. It isn't all about putting the latest hardware, more disk or more RAM. Scaling is a subtle art of discovering pain points in the application and using various Open Source software and technologies to get you to where you want. Read more.

Software programming has come a long way for students and younger children since the days of Logo. Syntax has been replaced with connecting blocks and the triangle turtle has been replaced with custom artwork children create themselves. Now, multi-threading and event processing are easier to teach children than functions, and this session discusses these ideas as well as so the edge of kid code. Read more.
