Why is systemd-oomd still a thing
Personally I thought https://github.com/hakavlad/nohang worked pretty well, and it'll also notify the user if it's about to start killing things, but I haven't bothered to install it in fedora. I did tweak the systemd-oomd config to be less aggressive though.

Arch linux randomly freezes, especially when playing a youtube video or performing other video-related workload
SOLUTION: After struggling with this nightmarish unpredictable kernel panic for two weeks, I confirmed nohang is capable of stopping this problem for real.

How do i install packages in ZORIN OS
I'm trying to install this app called " nohang" for memory problems. https://github.com/hakavlad/nohang i wasn't sure which type zorin is based on.

Am I doing RAM wrong?
Thanks. Looking into this as well. Further digging in this sub over the past couple days have brought up earlyoom as well as https://github.com/hakavlad/nohang as interesting things to pursue.

Distro with best ram management on 8gb of memory?
Sounds like the complaints indicated on nohang's repo. I also have low memory. nohang and zram make mine work better than macs/wins with higher memory.

The case of the programs that were launched with impossible command line options
Oh that’s a known problem. There are many patch sets floating around that fix it by triggering the OOM killer when the system is thrashing: https://github.com/hakavlad/le9-patch
I’ve never ran into this specific problem back when I was daily driving desktop Linux, but I did run into 1000 similar ones that needed bandaid solutions. It’s death of a thousand cuts: https://news.ycombinator.com/item?id=28490753

Help me out here, why does Windows 10 handle my low memory situation better than Linux (so far)? How do I fix it?
I actually do use the Zen kernel already. If you are already using the zen kernel , make sure to use the latest one which has le9 patches , imho this patch can Improve user experience in tight memory situations. Check this https://github.com/hakavlad/le9-patch, saw many people praise this , but ymmv. Best of luck

Moving Google Toward the Mainline
- Limit the amount of thrashing or protect some pages from being reclaimed. This has been proposed by Google first and several other people since then, but AFAIK it has never been implemented in the mainline kernel.
Regarding the latter solution, there is a patchset called le9-patch[1] that is included in some alternative Linux kernels and it should be relatively safe to use.

nohang: A sophisticated low memory handler for Linux
Patch i was talking about le9-patch. it's only a proof of concept with very rough edges, but consider it isn't written by an experienced kernel developer with deep knowledge of memory subsystem.
