Next week we will be learning how to get things done in an Ajax-y way using jQuery on the app engine. The video below goes over an example from the author's book (which is a good, high-level introduction to using the app engine) so it might be a bit confusing at first. Basically, he is building a chat application where each client uses setTimeout to send back an XHR request every 4 seconds asking for all messages. The client then displays all (maybe some new) messages. I will be doing a different example in class.
