The creator of Handmade Hero[0] has regular C++ streams on YouTube[1].
Jonathan Blow (creator of Braid and The Witness) sometimes streams[2] development of his language, Jai. He does write some C++ when he digs into compiler internals, but it's mostly in Jai.
I've been interested in checking out Handmade Hero, but haven't yet found the time to start looking at it. One thing I would like to know though is what game they're actually making. Now that it's been going on for some time, is there a video somewhere of what kind of game is being made?
You might want to check his YouTubee stream[0]. He's currently finishing the lighting engine; if you browse through his latest video, you will occasionally see how the scene looks like.

Personally, I trawled twitch for a while looking for someone working with C++.
Does anyone have recommendations?
