I use Alpine Linux. It’s exceptionally stable, great for pretty much any device and is best for small VPS with limited space/ram. Nice package manager too, but it is limited in packages.
It works great for me since I only use docker containers, but some things outside docker may require something like Debian instead.
Jesus, even before I read the article it read like the U.S wants to emulate disinformation campaigns others are using. The irony of three letter agencies condemning AI campaigns while the Pentagon is going “We want that”, is insane but its to be expected I guess.
