gamecore sounds like a style of music I’d be really into.
(4am thoughts are sometimes intrusive.)
Also if you’re interested in this kind of thing, “operating systems in three easy pieces” was surprisingly good. https://pages.cs.wisc.edu/~remzi/OSTEP/ https://pages.cs.wisc.edu/~remzi/OSTEP/
It’ll teach you all the history behind the OS decisions we take for granted now. I was delighted to learn that early OS’s used to have only one global lock. Sounds silly, but it’s extremely effective — HN does the same.
It has a bunch of chapters presenting these kinds of “games” user programs can play to get an advantage against the schedulers.
Also it’s $10 for instant access to a pdf. I was amazed. Buying a book is always such a hassle, except this time it was 30 seconds.

- twoodfin 4y agoMy understanding is that many OS kernels into the 1980’s didn’t even have a single lock: Because the only thing that could switch the sole—this is assumed to be a uniprocessor—running kernel “thread” was a hardware interrupt, critical sections would be protected by simply disabling interrupts.

Linux without CONFIG_SMP and CONFIG_PREEMPT simply disables interrupts when the code asks for a lock. https://www.kernel.org/doc/htmldocs/kernel-locking/uniprocessor.html https://www.kernel.org/doc/htmldocs/kernel-locking/uniproces...
