alt Hacker NewsI don't understand why the default way to show RAM usage on Linux isn't to simply show "In Use vs. Available".
I don't care how much cache is being used and I can't really do anything about it even if I did.

atop (one of the many variants of top) reports numbers for "free", "available", and "cache" in its total systems report. As long as "available" is high, I don't worry about the RAM.
Cache is super important though. Not having enough memory for cache will tank your system performance, even if you have a ton of "available" memory
