Google I/O 2009: Advanced Techniques, AJAX API Playground
In this session, learn advanced Javascript, why App Engine is so easy to develop on, protecting from XSRF vulnerabilities, cutting the load time of your app in half, and hear about general client-side web app techniques. These lessons are taught in the context of the design and development of the AJAX API Playground (http://code.google.com/apis/ajax/playground/), a tool which can help developers learn about and experiment with many of Google's APIs.
