Yes, lmz <https://news.ycombinator.com/user?id=lmz> pointed out that I had mixed up Dave Plummer and Dave Cutler. There are actually multiple videos that Dave Plummer has done with Dave Cutler, which I found very interesting.

Reminds me of Coders At Work, by Peter Seibel, which I read right around the time that I decided to get deeper into software. Being able to read or hear about the process that went on in someone's head while developing something so major was and is still impressive, and motivating.
