Software Carpentry in Three and a Half Minutes
I had a chance to give a quick pitch for Software Carpentry yesterday, which I’ve since recorded and posted to our web site. I hope it’s a useful overview of what we’re trying to do and why; I’d be very grateful for ideas about improving it.
Note: a newer version of the pitch, titled “Software Carpentry in Ninety Seconds“, is now available.

A couple minor points:
The running water (was it raining?) in the background in the audio track is a little distracting.
At 1:20 the grammar in the slide is a little awkward (“Dramatically improvement in productivitiy”), you had it fine in the audio though: “Dramatic improvement in productivity”.
