LaurieWired does some interesting, if very niche, stuff on C++ programming techniques. I also enjoy some of Dave’s Garage (thinking of his recent video on CAN Bus architecture); I don’t love the generative graphics he sometimes uses but his lecture-style videos are very tightly-written and well-delivered. His interviews with Raymond Chen and Dave Cutler were great as well (and it’s nice to hear about the days before Microsoft became a slop factory).

You might enjoy Cathode Ray Dude; he doesn’t really do general tech videos (they’re more like TechMoan, deep dives down unique rabbit holes), and his release cadence is definitely that of a one-man operation, but I really like his presentation style and depth of research.
