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!

    And funnily enough, the kernel doesn't follow the unix philosophy either as far as I know.

    I have heard that before in a joke setting, I would love to hear genuine arguments for and against it.

    The debate is as old as Linux itself, and well documented.

    It doesn't seem to be a debate. "Microkernels are better" "yes but I don't have the time for it" but thanks

    At a high level, microkernels push as much as possible into userspace, and monolithic kernels keep drivers in kernel space

    There are arguments for each e.g. a buggy driver can’t write into the memory space of another driver as easily in a micro kernel, however it’s running in the same security level as userspace code. People will make arguments for both sides of which is more secure

    Monolithic kernels also tended to be more performant at the time, as you didn’t have to context switch between ring 0 and ring 1 in the CPU to perform driver calls - we also regularly share memory directly between drivers

    These days pretty much all kernels have moved to a hybrid kernel, as neither a truly monolithic kernel nor a truly micro kernel works outside of theoretical debates

    Thanks! I will look into
