“de facto” literally means that it wasn’t decided.

Using “All” is the best way to find those. How else are you really supposed to?

This is why i think subject tagging for communities makes a lot of sense. I want to remove anime, k-pop, video games, sports, region-specific, tv/movie, “anarchy”/“everything sucks” and plenty of other entire categories from my “All” feed, but blocking is a never-ending effort.

I think a lot of modern kernels are “tickless” - they don’t use a timeslice timer, and only context switch on IO interrupt, process yield, or when timeouts are specifically requested (including capping cpu-bound processes). https://en.m.wikipedia.org/wiki/Tickless_kernel
