See the big belly about 1/4 of the way through the video. Excellent for that reason alone, but really a great overview by Jason Seifer on some finer points of Javascript coding and development philosophy in general.
Some topics covered in the video:

Semantic Markup
Obtrusive Examples <– big belly here
Benefits of coding unobtrusively
Examples, specifically to Rails
Guidelines and assumptions you should make when coding javascript
