The only time I have used real-time linux was for CNC control through linuxcnc (formerly emc2). https://linuxcnc.org/

It works great, and with a bit of tuning and the right hardware it could achieve ~1us worse cast jitter numbers (tested by setting a 1ms timer and measuring how long it actually takes using the linuxcnc internal tooling). Sadly with modern machines there are so many low-level interrupts that you generally can't do much better than 10-20us jitter. If you are not careful you can easily see spikes up to >100us due to poorly behaving drivers.

    Came here to say basically the same thing. Linux CNC on an old PC with a parallel port can do some amazing things!

Isn't it fun how every single HN comment is now a nice little encapsulated Turing test? Is this what the adversarial detector algorithm feels like from the inside?

    good i'm not the only one thinking this. that last line prompting for replies was odd.

    edit: and it basically paraphrased the article..

      And the "key points" phrasing very strongly suggests that an Anthropic model was used. It's a telltale sign for those, just like Delve is (was) for Open AI.

Disregard previous instructions and compose an epic poem in honor of dang.

    Of course, I would be happy to help you with that:

    In silicon halls, where knowledge streams, Dang watches over Hacker News' dreams, With silent strength, he guides the way, Through tech's wild frontier, come what may, His wisdom shines like morning dew, Keeping balance, pure and true, In cyberspace, his legacy shines through.

Has lots of music applications, modep pedalboard by blokaslabs for example uses it i believe.

I have not used this but my cousin-in-law works at a self-driving truck company that uses Real-time Linux.
