2. Be civil
  • Understand the difference between a joke and an insult.
  • Do not harrass or attack users for any reason. This includes using blanket terms, like "every user of thing".
  • Don't get baited into back-and-forth insults. We are not animals.
  • 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.
    • 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, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.
    • 5. πŸ‡¬πŸ‡§ Language/язык/Sprache

    Are Linux users really working in the kernel all that much? I’ve been doing support for Linux sysadmins for a decade and not once have I needed to touch the kernel.

    [–] Xatolos@reddthat.com 6 points 1 week ago (1 children)

    I mis-phrased that, sorry. In the Android case, you can't access a lot of networking functionality and other lower level access functions.

    Running ifconfig responses with:

    Warning: cannot open /proc/net/dev (Permission denied). Limited output.

    Even though it is based on Linux, and has access to the ifconfig app, it's not really something you can do. There are other things to consider like that. While you could try to give yourself root access, it's messy and not something that's really easy or encouraged.

    In macOS's case, it's Unix to a point, but try installing NVIDIA cards in them (for CUDA cores). There are Unix drivers for Nvidia cards, for x86 and ARM, but even thought it's Unix, it still won't work.

    How about running native Vulcan? It's a major API for 3D graphics. It has a Unix driver, but still can't work on macOS. Best that can be done is workarounds, but that's not native and has issues.

    There is Unix support for these, but macOS isn't really Unix underneath.

    Okay, that makes more sense. Though the amount of trouble I've heard Linux folks have with Nvidia stuff shouldn't mean that it's not Linux. Just that Nvidia sucks.

    Also, Vulkan seems to have a ton of support for Apple Silicon.

    And finally, Mac OS has been certified Unix 03 since 2009 except for version 10.7

    [–] Xatolos@reddthat.com 1 points 1 week ago

    Vulkan has hacked in support, but not official support. It's like saying that because I can hack in Flash on macOS, that must mean that it has tons of support. Two different things.

    And macOS is Unix certified, but that doesn't make it Unix (I know, it's complicated...) To help show this, EulerOS (from Huawei) is a Linux OS.

    EulerOS is a high-security, highly scalable, high-performance, open enterprise Linux operating system

    Its was also Unix 03 certified, just like macOS. Even though it's Linux, not Unix.
