ccruz: In my slides I have a Cuzillion page that shows how an inline script with a 5 second loop blocks the page from rendering:

To show how setTimeout avoids the problem I took the document source from that example and wrapped the 5 second loop in a function called through setTimeout:

You can use the “Now:” time value to see that this second example renders immediately.

Hi Steve,

Your Web 2.0 session was easily one of the most valuable I attended.

I had one lingering question, though. You mentioned that large chunks of inline script will block page rendering and suggested using setTimeout’s to circumvent the problem.

Could you please provide a code sample of this technique in action?

Thanks so much!!

believe I found an anomaly in YSlow. some extensions values in the yslow.js are not being being picked up. I have found the extension values are being defaulted to the values in lint.js, specifically:
pref(”extensions.firebug.yslow.pointsGzip”, 1);
pref(”extensions.firebug.yslow.gzipFileSize”, 700);
What I found was the yslowFirebug.js getPref() would receive a “undefined” type as the nsiPrefBranch type is INVALID (0)

Steve,

That looks really interesting. It’s too bad that I will be attending the MySQL conference just the previous week, or I would try to attend Web 2.0 for your session.

Maybe you could include those new rules into the 2nd edition of your book?
