Ask HN: High Quality Screencasts

Over the years I've learned a great deal from high quality screen casts. When focused on iOS, Swift Talk and Point Free have given me real gold nuggets of knowledge. Recently I've started making my way through the content on Destroy All Software, which though somewhat vintage, still holds its own and transcends Ruby/Rails. What sets these apart for me is the incidental learning that comes from watching deeply experienced engineers at work.

My question is, irrespective of platform, are there others in that calibre that you would recommend in 2020?
