I’ve never lectured with a bell before. You see it in the middle of the picture above, just to the right of my hand. When I mess up in my lecture—and I mess up often—I ring the bell. Udacity’s video editors see the characteristic signature of the bell in the audio track and can zip right to it while they’re editing; they save a little time this way. It takes about eight hours for me to record an hour-long unit. As you might imagine, I ring the bell a lot.
