Using CouchDB to create "edgy" web applications that are stored in the database. CouchApps allows you to store not only data in a database like CouchDB, but also full applications, which lends to some rather interesting use cases. Not only do applications then scale up and out, but their ability to revision control themselves comes for free. The CouchApps are pure JavaScript applications that sit on top of the power of CouchDB, and then allow the applications and data to become instantly portable and shareable through replication. This tag team presentation will give you some powerful insight into the concepts of CouchDB and CouchApps.

Stoyan takes a deep dive into web technology and how to optimize it at levels that rarely get touched upon, even at tech conferences. His experience in pipelining, cacheing, image inlining, and smushing at Yahoo! Developer Network is shared with you to take advantage of every possible performance improvement ever known.

Grown tired of the AJAX buzzword blues? Jack Moffitt takes us on a whirlwind tour of Strophe for building beautiful XMPP based applications in pure JavaScript using Bidirectional-streams Over Synchronous HTTP (BOSH) which will most likely be the next evolution of web technologies. The focus concept is the "Real Time Web" and how to actually accomplish low latency rich data applications that put AJAX to shame. With Strophe you can leverage all the goodness of XMPP at the client side. It is a very exciting technology and great deep tech talk from the one of the geniuses behind the brand new Collecta.

John Resig presents his mystery topic, which is actually three topics that strike his interest.

This is followed by JavaScript Games which he unveils some super cool hidden functionality (cheat codes++) on the jQuery web site. This is followed up by the introduction of Johnapos;s distributed continuous test framework platform, Test Swarm. It is jam packed with Nirvana and goodness so be sure to watch both parts.
