Agreed, and he's programming like I do with pointers; no clue, just add/remove * and & until it compiles! Xo

My question is, how does he record the display?!

Also user->name for the love of god!

There's a ton of ways it could be done. Looks like a camera pointed right at a monitor, and a webcam recording him. You can have various display sources and picture in picture looking stuff using an app called OBS ( https://obsproject.com/ ) which also allows you to stream everything, if you feel compelled.

Here's a picture of his setup https://jcs.org/system6c

He talks in the intro video also linked there that he's trying to get a better set up to directly connect into the screen but for now has to deal with looking through the screen on his phone recording the Mac.
