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.

    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.

    This site says Linux calls cached RAM "free" but in my screen shot it's definitely being shown as "used". I guess this is a choice of this app?

    Most likely, try running htop or top (can't remember which is which) in a terminal.

    [–] Dave@lemmy.nz 3 points 16 hours ago (2 children)

    Well top currently shows:

    MiB Mem :  64076.1 total,   2630.3 free,  51614.1 used,  34046.9 buff/cache     
    MiB Swap:   4096.0 total,      2.3 free,   4093.7 used.  12462.0 avail Mem 
    

    While the "Mission Center" app shows:

    67GB RAM total, 54GB RAM in use. 12GB available. 29GB cached.

    Subtract cached and free from total to get actual usage Htop shows visually though with cached as yellow or so I think you are using about 30 gb ram.

    Honestly, apart from firefox, what are you running? Does that include vms? I have 8GiB ram(7.1 usable) and uses like 1.8gb on idle and about 5-6.5gb on my personal highest usage

    [–] Dave@lemmy.nz 1 points 41 minutes ago

    No VMs. The RAM usage kept climbing until I was crashed out to the login screen and lost everything that was open. It seemed to be a particular website that gobbled RAM.
