Just as a side comment: every time you open OBS to get ready for a lecture, do a quick test record and playback of your recording to make sure everything’s working. Since you’re not streaming live, there’s no way to check if it’s all working right until after the lecture when it’s too late. I’ve struggled with my operating system randomly picking my laptop or webcam microphone instead of my usb microphone as “default”

I don’t think Makefile and CMake should count as programming languages in this context. There are a few weird names on the list, but these are high up the list only because they’re glue for C/C++ projects
