Premade AppImage or self-contained binary, I’ll usually drop it into ~/.local/bin.

Something I have to compile, I’ll usually do in a dockerfile tracked in my dotfiles repo.

Only thing I’ve compiled from source on my host in the last year is https://github.com/werman/noise-suppression-for-voice.

Could just be my use cases now compared to 10 years ago, but I’ve just found I’m rarely compiling these days on the host system. At least the configure-make-install or ninja variety. I’m sure I install a package here or there that does it in the background. Numpy comes to mind or an AUR package with Arch.
