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.
  • 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, <loves/tolerates/hates> systemd, and wants to interject for a moment. You can stop now.

    Gives a lot of Space for running Virtual machines.

    Also browsers can chew that up fast if you have a lot of tabs, Firefox has managed to do it a few times. At least until I started limiting its RAM to 8GB (best decision ever)

    Limit Firefox to 8GB of RAM .desktop file

    [Desktop Entry]
    Version=1.0
    Name=Firefox RAM limit 8GB
    GenericName=Firefox Ram limit 8GB
    Comment=Limit RAM for Firefox to 8GB;
    Exec=systemd-run --user --scope -p MemoryLimit=8G firefox
    Icon=firefox
    Type=Application
    Terminal=false
    Categories=Utility;Development;
    StartupWMClass=Firefox
    

    (To use it with other apps like Chrome or Electron apps just replace the command at the end, and startup class with the ones from the program you'd like to run. Icon and Name changes are optional but might be desirable so you remember what app it is for).

    Alternatively you can open about:config and limit memory usage there. For example limit in-memory cache.

    EDIT: it seems firefox doesn't allow to set RAM limits yet, only cache sizes

    That's good to know, I don't know how well it would work though I feel like I enabled something about closing background tabs to reduce memory load (it might have been what you said, it might have been something else I don't really remember) and it helped a little bit but it still ended up chewing up a lot of memory.

    Setting the limit though did help immediately. And stop the overconsumption problems, occasionally a couple of tabs crash here and there but it doesn't freeze or worse cause other apps to slow down and freeze. Which did happen before.
