Huh, I never actually gave any thought to how the SysRq key works. Interesting thing to learn after all these decades, heh

Unix internals is a great book! If you haven't had an occasion to read it, I can't recommend it highly enough. Similar to design of the BSD operating system, it goes into the internal data structures, but most importantly the rationale

I actually don't know nearly enough about OS design, and I've been toying with the idea of learning more for like 20 years now but never manage to get around to it. How's that book hold up, considering it was (apparently?) published in '96? I'd assume a lot of the basics are still the same, and since it's a book about the "evolution" of UNIX the historical parts will still be interesting in any case

I love abusing sigusr1 and 2. Absolutely no confusion or shooting myself in the foot in 3 months when I forget what I did... No sir
Dude(ette): You're following them around and bordering on harassment. Chill.
Yeah you're really showing them how you have the moral high ground by following them to other posts and harassing them there... ???
