John Resig on Advanced Javascript to Improve your Web App (opens in new tab)

so now we can dynamically load content chunks to the dom... and the server can determine if the request was made by jquery.

dude, web development is getting impossible... there's just wayyy to much to keep in mind. especially while trying to utilize all the css3 and html5 features.

you could just optimize 1 site forever.

Excellent talk by Resig. Plenty of concrete practices rather than the vague bullet points you usually get in a talk.

The part about dropping IE6 not impacting jQuery is interesting. I personally get burned by IE7 when using jQuery much more often than IE6. Which also makes me sad, because he's right about IE7 shipping bundled with IE8 and also right about IE8 is going to be around for quite a long while. Sigh.
