Community rules (click to expand)

1. Follow the site-wide rules

2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack members of the community for any reason.
  • Leave remarks of "peasantry" to the PCMR community. If you dislike an OS/service/application, attack the thing you dislike, not the individuals who use it. Some people may not have a choice.
  • Bigotry will not be tolerated.
  • These rules are somewhat loosened when the subject is a public figure. Still, do not attack their person or incite harrassment.
    • 3. Post Linux-related content
  • Including Unix and BSD.
  • Non-Linux content is acceptable as long as it makes a reference to Linux. For example, the poorly made mockery of sudo in Windows.
  • No porn. Even if you watch it on a Linux machine.
    • 4. No recent reposts
  • Everybody uses Arch btw, can't quit Vim, and wants to interject for a moment. You can stop now.
    •  

    Please report posts and comments that break these rules!

    Important: never execute code or follow advice that you don't understand or can't verify, especially here. The word of the day is credibility. This is a meme community -- even the most helpful comments might just be shitposts that can damage your system. Be aware, be smart, don't fork-bomb your computer.

    Linux is not a real-time OS*. For a car ECU, something like Speeduino would be a more appropriate choice.

    (* Or wasn't until a week or so ago, at least. https://www.zdnet.com/article/20-years-later-real-time-linux-makes-it-to-the-kernel-really/)

    That’s the joke 😉

    You could certainly do it but let’s hope that fuel injection timings and realtime system response aren’t that important to you.

    Worked with the guy, he was a true kernel monster.

    That's really cool! Do you know of real-world systems using this?

    Know some router platforms that used this and vfio to implement dpdk switching and routing under a Linux control plane.

    Brilliant guys worked on that, think some of the smartnics like Amazon and oracles use it too.
