The crashes are in the middle of browsers (both Firefox and chrome embedded in Spotify), if you try a simple mprime stress test (from the AUR mprime-bin) does it crash too?
I use paru and the default is “paru” with no parameter for the upgrade. But I am on your team here: I have to Google everysingletime the -Q params for all the queries and I have been using arch for almost 2 decades now: “who owns this file?” “what are the deps of this package?” “Which packages are installed?” “Which packages I explicitly installed vs dependencies?” Not a single one of them is intuitive to query with the pacman command line for some reason.
For me: Gentoo is a meta distro, you are the distro maintainer then the power user of that specific distro you created for yourself which can definitely be fun. Arch is more like: let’s give you one instance of a Gentoo distro when you are tired of being the distro maintainer.
The rust one is called bottom (btm) see the other thread :). When you already have a rust environment it is just at a cargo install away which is convenient.
