If you like this kind of post, you might like this “htop explained” post.
the end struck me - a picture of an os book. I wonder if students these days retain their books after college, or do they get returned as a rental?
I wonder if these btop fixes got into the standard ports collection? Or even upstream?
I like the command for viewing the ARC cache size, never knew that. It's only 2GB on my system (of 64GB RAM).
Great job on getting the fixes merged!
Interesting post, it made me wonder. At one time FreeBSD swap usage/logic was far better than what Linux did. Is that still the case ?

ZFS cache. The end.
User installs an unfamiliar server OS with an enterprise filesystem and is stunned when it works differently. I fail to see a teachable moment here.
This is why I use Linux. :>
Poor FreeBSD folks though. After so many years trying to present themselves as better alternative, the road just got steeper ...

I don’t understand the part about using heuristics and deciding what counts as used memory…
Used memory for the system is always total minus available.
Heuristics? I would hope that the system knows precisely what is using every single byte of physical and virtual memory. Is this a reporting problem? Why do we have to settle for heuristics and not the exact number?
As for the “unauthorized” sign:
Book publishers used to print India/SEA-only editions of books only sold in those countries, significantly cheaper than in the US or Europe. Then a Thai guy realized that this would be a good business opportunity: buy cheaper books and then import them to the US. Wiley brought him to court, went to the SCOTUS, Wiley lost the case. So they ended up printing cheaper edition books.

Mind you "price discrimination" like this still exist in the digital world where locality is easier to be enforced. For example Steam has extensive regional pricing across countries so the same game can be significantly cheaper in Russia, India, Brazil etc. compared to US or EU
