I bought a domain to illustrate my point:https://shouldiusethreads.com

@sir what about hyperthreading?

@sir what about hyperthreading? Does that breach the "no threads" rule?

@nergal it gets more complicated when you start talking about kernels and hardware. The answer is still "no", but with more caveats.

@sir I feel as though at least some of QEMUs use of threads in justified. I'm less certain of our use of coroutines 😉

@sir You should link all these pages using vanity domains on another page for ease of reference, like the git send-email and git rebase one.

@sir It could maybe even be worth mentioning that shared memory is a thing, so you don't even need to give up performance if you're doing something like image processing where there's a ton of shared state - just explicitly put that state in shm.The advantage of threads though is cross platform support (Windows can't multiprocess) and that a multiprocessing event loop system is way more code than `#pragma omp parallel for`.

@sir A lot of application use multithreading where coroutines would be enough and make the execution non-deterministic for no good reason. Yet, unfortunately, there are CPU bound tasks where the cost of spawning processes and doing messaging is too high and that makes threads useful. I blame languages for not abstracting the concurrency problem better.

@sir You seem to do that a lot, what with useplaintext.email and git-send-email.io. What's the reasoning for spreading stuff across many domains?

@sir Awesome! now everytime i use the "threading" module on python i will remember your site, i may end up not using threads and link the domain at the top as a reason of it.

@sir 1. what a good reason to buy a domain! :-)2. I thought it was about "threads" in the Fediverse/Mastodon (spoiler: it's not)

@mort @sir Shared memory across threads completely kills the cache though
