I haven’t been to OSCON (O’Reilly Open Source Convention) in years, so I’m glad to see that more and more presenters are making their slides available online. It isn’t the same as being there, but it is better than nothing.
The Javascript Boot Camp Tutorial has slides and source code available. I just finished a quick run through of the PDF slides, very cool. These slides are a great intro into Javascript. I think I’ll keep a copy around for reference later.
