Some Chromium colleagues found this useful, so I'm sharing it here too.

3/3 I hope to do a similar video sometime soon showing Pernosco pernos.co/ (a commercial product), which is even more powerful, and what I've been using for most of my debugging lately. My first attempt at a video didn't work out that well, though.

I did do the @_pernosco_ video, posted in this separate thread:
1/5 Last week I mentioned I'd also share a demo of @_pernosco_, which is a debugger whose interface is designed for record-and-replay debugging, although the debugging itself is less about replay than about moving between program states of interest.
