Powering the real-time web with Python: PubSubHubbub on App Engine
Presented by Brett Slatkin
PubSubHubbub is an open protocol that turns Atom and RSS feeds into real-time streams. I built the reference Hub run by Google using Python and App Engine. In this talk you will learn how I made the real-time system work: An intro to the protocol, asynchronous processing on App Engine, fault-tolerance, and scalability.
