Read HN all day looking at all the interesting ideas people are posting! C'mon you know this is what you're going to do anyway. Just kidding. But, hopefully we don't see you back here till Monday w/ some more wisdom and knowledge to drop on us all.

Just to add to the mix. How about TED Lectures, youtube around for old Feynman or Steve Jobs videos, check out OpenCourseWare or any of those online learning sites and make a dent in an interesting course. Catch up w/ friends on the phone.

I also second the jQuery, Python, Django, Google App Engine, and Processing crews.

Hope your ankle gets better soon!
