Performance, Games, and Distributed Testing in JavaScript
by John Resig
John Resig presents his mystery topic, which is actually three topics that strike his interest. First up is measuring performance and a quick introduction to benchmarking (and its positives and negatives). 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 John's distributed continuous test framework platform, Test Swarm. It is jam packed with Nirvana and goodness so be sure to watch both parts.

Bending JavaScript to your will, or why testing JavaScript in the browser can drive you crazy
This talk will cover the previously untold story of Selenium's JavaScript internals. You'll learn how Selenium had to trick the browser's single-threaded JavaScript engine into a continuation machine to wait for things like page loads or returned Ajax messages. You'll also learn how Selenium could have used Brendan Eich's Narcissus meta-circular JavaScript interpreter to clean up the mess, and why Narcissus is just really run to play with. (Hint: You can use Narcissus as a code pre-processor to tweak JavaScript into your own little language. Want optional parens on function calls? Done!)
