    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).

      Oh my god thanks but what if someone had a systemd free system

      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)

      The other day my laptop was sluggish as hell, checked top and turns out Discord and Orca Slicer were maxing out my cores

        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…

    Try realizing ten thousand mesh instances in Blender and watch that sucker eat the rest of your RAM like it’s got a pebble in its shoe.

    I did that on my work PC with 128 GB memory (originally built for esports shit) and it still wasn’t enough.

        It was also supposed to be an all-in-one recording/streaming computer for university events, and they had to use the budget for something. It ended up being used as a proxmox host for a while, then it was handed off to me. Now the most resource-intensive thing it runs is a Windows 11 VM that I torture mercilessly use for experiments. It rarely gets to 10% memory utilization.

            It has an i9 10980, so about 4-5 years old. It was built before I was hired.

    Can’t relate, just upgraded my laptop from 32GB to 64GB since VScode would keep closing due to OOM. What? Oh, no, it’s not vscode’s fault…I keep like 5 Firefox windows with 30+ tabs open, like a fucking maniac… Close them? What do you mean “close” them?

    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.

        Tiny Core Linux is a minimal Linux kernel based operating system focusing on providing a base system using BusyBox and FLTK. It was developed by Robert Shingledecker, who was previously the lead developer of Damn Small Linux.

        Ah, that explains a lot! Didn’t know about TCL.

        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
