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 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, no politics, no trolling or ragebaiting.
  • 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
  • This is primarily an English-speaking community. πŸ‡¬πŸ‡§πŸ‡¦πŸ‡ΊπŸ‡ΊπŸ‡Έ
  • Comments written in other languages are allowed.
  • The substance of a post should be comprehensible for people who only speak English.
  • Titles and post bodies written in other languages will be allowed, but only as long as the above rule is observed.
  • 6. (NEW!) Regarding public figuresWe all have our opinions, and certain public figures can be divisive. Keep in mind that this is a community for memes and light-hearted fun, not for airing grievances or leveling accusations.
  • Keep discussions polite and free of disparagement.
  • We are never in possession of all of the facts. Defamatory comments will not be tolerated.
  • Discussions that get too heated will be locked and offending comments removed.
  • Β 

    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 remove France.

    screen shot of memory usage by app, showing Firefox using over 18GB of RAM

    I also don't understand why every chat app needs 1GB of RAM to itself.

    It absolutely will try, it just gets killed by the oom reaper.

    I've used Linux for years and never in my life have I seen anything crash or close because of a oom killer. It's myth for me that it exists. Me looking at my firefox occupying 6GB of the 8GB ram and opening intellij so it becomes full and swap is on 3GB.

    Its not a myth at all. If a software uses too much RAM it has to be killed because otherwise the OS crashes. You can read more about it here: https://linux-mm.org/OOM_Killer

    Here is the source code: https://codebrowser.dev/linux/linux/mm/oom_kill.c.html

    It is just not very tuned for desktop as it will lock up the system and empty every single type of buffer in the kernel before it is actually invoked.

    It depends on the app. For some apps it just kills the app and everything is happy
