I've been wondering whether it's better for memory pages to be compressed at the hypervisor level, or on the VM level.

I'm leaning toward the VM level, because

1: VMs have better knowledge of memory pressure by the application, and can better decide when to swap pages out to zram. The VM has access to information about memory pages that the hypervisor doesn't have.

2: if pages are compressed on the hypervisor level, the VM doesn't "see" any increased memory available. The host box gains free memory, but the application never sees it to make use of it, it'll just see the same 8GB as it always has, so it never really benefits. This maybe lets you host more VMs on one box, but at the cost of the applications not being as efficient.

Is this a reasonable position? I'm wondering if I'm missing something obvious.

I'm a little choked up.

18 years is a pretty good run for a cat, but yeah.

Interesting comment on a post.

Tldr: Zebra Mussels reach a balance that prevents them from being a totally catastrophic invasive.

"The Department of Government Efficiency, Musk's vehicle. made news by "discovering" the General Services Administration uses tapes, and plans to save $1M by switching to something else (disks, or cloud-based storage)."

Oliv on Steam created a set of very nice maps for TLD zones, including the new Zone of Contamination.

From a Youtube comment:

"Sadly the creator of this mash-up has passed away. His name was Erwin Beekveld and he died on 30th of march 2022 aged 52. Thank you for all the joy you gave us, Erwin. Rest In Peace"

Pour one out for an OG memelord.
