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!

    Also, anyone who says “try this, it’s neat”:

    :(){ :|:& };:

    Don’t. It’ll lock up your computer. The markdown is adding code to the above. Ignore the “amp;”. It’s just an ampersand.

    Also anyone who tells you run level 6 is the best one…

    Don’t. It’ll set you in a boot loop.

    Basically, Google whatever someone suggests to you just to verify they’re not being a dick. I would say spend a bunch of time in the command line interface (CLI). There’s nothing wrong with the GUI desktop, but the real power of Linux is in the CLI because you can do so much with it. It’ll also get you on the road to scripting, if you’d like. That unleashes the power even more by making your Linux box so cool stuff on its own. Then learn the power of cron tables (crontab) so that you can schedule your computer to do cool things on its own.

    Good luck and have fun!

    A fork bomb no longer works on modern distros which use systemd btw, since systemd imposes limits on the user and system cgroups (IIRC, a user can't have more than ~10,000 tasks or something).

    If you are low on memory, a fork bomb still works

    I can confirm that it crashed my laptop running fedora 36 (this was a while ago lol)

    Just tested and confirm it doesn't work on Fedora 38. When you run it, you get an error saying:

    bash: fork: retry: Resource temporarily unavailable.

    It still does the loop, but doesn't slow down the system or anything, and you can easily close the terminal window.

    As I said before, systemd imposes cgroup limits per user so fork bombs no longer work.
