It's okay to teach a little tmux, a little notebooks, and a little AWS each lesson, rather than the course be topic by topic. I agree with your point that it's a better way to teach material in a course, because it allows you to get people started doing things.
My point was that within a lesson, you should separate topics, because people don't handle the topic switches well when trying to listen -- it's basically just a cache/stack smash. Diversions are distracting, even when materials are interwoven in the course.
