Can anyone recommend a youtube video of someone using rr effectively? I've used it a few times, and enjoyed it, but I feel limited by my beginner gdb skills. I

  That’s an excellent idea. Debuggers certainly need better documentation, and guided tours are a good way to teach skills. Some of the Mozilla folks did livestreams of their development work on Firefox, including debugging sessions. I haven’t watched any lately, but you might search them out. If they kept it up then they might be using RR now, instead of just GDB. Here’s a demo video for Pernosco: https://robert.ocallahan.org/2019/10/pernosco-demo-video.html https://robert.ocallahan.org/2019/10/pernosco-demo-video.htm... Pernosco is based on RR, but this probably won’t teach you anything about using RR, since the UI is so different. But it was a memorable one because Brendan Gregg produced a really good tutorial for GDB, where he debugged a real problem in a real program (instead of a made–up problem in a program written just to have a made–up problem inserted into it). The Pernosco demo debugs the same problem in the same program, so comparing the two can be quite easy. I would like to see someone the same type of tutorial for RR, and for other debuggers that people like.
