This is great and very useful to me! What source are you getting the channels from? And how do you choose which channel goes in?

As an amateur YouTuber myself, this is disconcerting. A real video takes quite a lot of effort to do properly, especially if you try to aim for depth. The guy is obviously smart, b…

As a (tenured) academic myself, I fully understand the flexibility (and the lack thereof). A staff of 50-100 sounds like a true nightmare. I've experienced classes of ~500 students…

It is unfortunate when a talented teacher, as the OP seems to be, turn to industry for (significantly) more money, but this seems to be the way the market works pretty much everywh…
