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.

    That'd be over 1TB with zram on

    This comment is how I learned about zram. Just one question, when is it used?

    [–] [email protected] 4 points 8 months ago* (last edited 8 months ago)

    Fedora enables it on all systems with <4GB (maybe a bit less I forget). It’s trivial to enable/disable it and see if its helpful for your usage.

    Yep. I just looked it up.

    I assumed it was like windows page file but it's ramdisk.

    Depends on config, ArchWiki recommends optmizing some sysctl values to take advantage of it

    it generally starts kicking in after >60% RAM usage even with this config
