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.

    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.

    can't it be done with a security key, like yubikey or similar?

    I think Heads (osresearch.net) uses security keys as a kind of substitute TPM, however that only works if you replace your - supported - PCs firmware with it.
    I don't know too much about how this works in particular, so I can't really compare it. safeboot.dev recommends Heads where possible, which I understand is partly due to safeboot relying on proprietary firmware implementations, while Heads uses libre software for the most part. Sadly the Heads firmware only supports older models/CPUs, which afaik don't receive (all) microcode updates, including one which weakens the IOMMU.
