    That’s how I got a free netbook. The netbook had 32GB flash with windows and office occupying 27+GB. Then windows wanted to do an update - with an 8+GB file. Spot the problem. And windows can get quite annoying with updates. As the netbook could not be expanded, and attempts to redirect the update to a USB stick did not work, a newer netbook was bought, and I got the old one. Linux plus libreoffice plus a bunch of extras happily sat in 4GB…

    i mean, some games (cough cough factorio cough cough) manage to use up about 25GB of ram on my system, so it’s nice to have a buffer. now, my 64GB may be considered a bit overkill but i call it future proofing

        Is Orca that resource intensive? I’m running it in a container with KasmVNC and have never really checked out the resource usage. Admittedly it’s on one of my local servers in another room. I guess it’s how large your projects are too.

        Edit: maybe it’s just my small projects

        What’s the benefit of running Discord’s app instead of just using it as a PWA? A PWA would reuse your existing browser and its session.

            Oh that’s a good point. I totally forgot that Discord has voice features. don’t use Discord often, and when I do, it’s just for text chat. Unfortunately some open source apps I use use Discord for communicating with the developers.

        Firefox unloads old tabs when restarting the browser, so most of those are more like temporary bookmarks.

        Don’t think I’ve ever seen someone open 300 tabs in one session or on Chromium…

    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.

        It might be harder for them but there are similar tools that they could use to limit it. One I’ve seen people use is firejail, a tool designed for sandboxing processes and applications.

        I’ve personally never tried it myself though so I can’t attest to how well it works, either for this purpose or sandboxing in general.

      Does it kill Firefox if it tries to go over the limit? I think I tried this once and if there is a memory leak it just closes itself (which is batter than hogging the whole system, bit still)

        No, it just limits the amount of RAM that Firefox (or whatever other application you launch with these parameters) will see.

        A few Firefox tabs may crash occasionally as a side effect. And obviously if Firefox eats up all of the 8GB it’s allocated it may crash itself though usually it doesn’t and tabs will crash before the browser crashes.

          I can confirm this, the first time I tried it out I accidentally set it to 1 GB, Firefox could only see that amount of memory. Though limiting Firefox to only 1GB its a very bad idea and it can cause it to crash it’s not because it’s trying to go over though it’s just because it ran out of memory.

          8GB is what I would consider the safe minimum for web browsing. If you said it lower you’ll have performance losses. Setting it higher though will only chew up valuable System RAM by inactive tabs.

        At my last WFH job my daily setup was firefox, sublime text, slack (electron app), github desktop (also electron), and 3 terminals, one running a local dev server. It all ran fine.

      it’s almost like the ram usage depends on the software / services you need to run /s

    I’ve seen builds of the Linux kernel that comfortably fits in my on-die CPU caches.

    So it would just be a picture of an empty sofa.

      There are mid range CPUs with 128MB of L3 cache now. A Linux distro like Tiny Core could fit entirely in cache.

        Hm? Do you mean a link to builds that are this small? My midrange Intel i5-12600K (I’m a working man, doc…) L3 cache is 20,971,520 bytes. My Linux Mint (basically Ubuntu kernel) vmlinuz right now is only 14,952,840 bytes. Sure, that’s a compressed kernel image not uncompressed, but consider this is a generic kernel built to run most desktops applications very comfortably and with wide hardware support. It’s not too hard to imagine fitting an uncompressed kernel into the same amount of space. Does that help to show they’re roughly on the same order of magnitude?

        Ten years old kernels could be 2 MB.

      My ARM board from 2010 has 256MB of memory. It runs an old 3.1 kernel (not attached to internet) , new kernels won’t fit/load. But on that I have OpenMediaVault running SAMBA shares and mindlna to serve music. It isn’t even using 50% of the 256MB

      Yeah. Firefox will gladly make itself comfy in my 32Gb… It’s annoying because just because 80% of RAM is “used” doesn’t mean it is really.

        this; every time the ublock origin absolutists insist that everyone must use Firefox or die I just wonder if they never open more than one or two tabs anyway. hell, a sufficiently complex web app running in a single tab can make FF choke

          You got it wrong actually. Firefox is not really actively using all the ram. It’s more like reserving it. The system does that too. When the actual used RAM gets low, Firefox releases some of this unused RAM.

          tell me you have no idea how firefox and ram reserving work without saying you have no idea how firefox and ram reserving work

          jokes aside, if the system needs the ram reserved by firefox, the system will get it. it is just faster to rserve ram that is expected to maybe be needed
