I’m hoping that’s just because I installed them on the same disk though.

No. It does not matter where they are installed.

Usually Grub successfully finds all distros installed. I guess that it fails because of some Atomic distro differences. If you use Grub from Fedora Atomic, it should also find a “normal” distro.

What is it and why should we care?

Absolutely wrong. Only the manual (I mean official documentation, not a “howto” in someone’s blog) can provide you a complete and up-to date information.

RTFM

It depends on what you mean by “local private network”. Probably, you need samba.

It doesn’t hide what’s under the hood and permits to fix/modify it. Yes, I’m a nerd.

I have no idea. It depends on your locale on mac.

You probably need to pass the iocharset mount option.

I almost never use xargs. The most common case for it is find, but it is easier to use its -exec option. Also, with find your example is incorrect. You forgot that file names can contain special characters, the newline character in particular. That’s why you need to pass -print0 option to find and -0 option to xargs.

Antivirus wont protect you if you run everything you find in the interhet. You need to be smart enough to avoid cracking. But if you are smart enough, you don’t need an antivirus.

Have you tried NetBSD?

Debian.

Your family will hate you if you’ll change their distro and DE every time you visit them. Distro hopping is normal for the first couple of years, but do it on your own machine.

Why custom? There’s 6.17 in trixie-backports.

I mean not much difference in hardware support.

Ubuntu is the wrong choice for any server.

In general, I agree. But I don’t want do participate in holy wars.

Don’t expect much difference between Debian and Ubuntu. I guess you just need to install a newer kernel package from backports.

What does dpkg --print-foreign-architectures say?

What are passwordless solutions in Windows for remote access, disk/filesystem encryption, keyrings?

BTW in all that cases a password can be replaced with a hardware token, for instance. It is just the simplest, most widely used and one of the less secure options.

Install updates regularly. Don’t install software from unofficial sources. If you see a recommendation like run curl something | sudo bash, ignore it. And, in general, don’t run anything as root unless you understand what you are doing and why this cannot be done without root privileges.

Most of what you enumerated is not a terminal emulator job. There is tmux for multiplexing, search and persistent sessions, for instance. And if you want image rendering, what a hell you use TUI for this? GUI programs can also be controlled with keyboard.
