Push notifications for web applications can change the way web applications behave - Real time updates, chat services, stock alerts, etc.

Welcome Websockets, node.js, backbone.js and Redis pubsub for different ways to push notifications. This talk is about how we use all these in Ruby. I will also briefly touch upon Pusher.com - the online API that can do this on production sites without any setup required! A Live demo is in the offing!
