From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Recommendations for after installing Linux (Mint) coming from Windows for best practices for a casual user ? (kbin.earth)

I finally bit the bullet and I'm giving Linux a second try, installed with dual boot a few days ago and making Linux Mint my default from now on.

There are a lot of guides and tips about the before and during the transition but not for after, so I was hoping to find some here.

Some example questions but I would like to hear any other things that come to mind:

I read that with Mint if you have a decent computer you don't need to do a swap partition? So I skipped that, but I'm not sure if I'd want to modify that swap file to make it bigger, is that just for giving extra ram if my hardware one is full? Because I have 48GB of ram and if I look into my System Monitor it says Swap is not available.

Was looking at this other post, and the article shared (about Linux security) seems so daunting, it's a lot. How much of it do I have to learn as a casual user that's not interested in meddling with the system much? Is the default firewall good enough to protect me from my own self to at least some degree? I was fine with just Windows Defender and not being too stupid about what I download and what links I click.

I was also reading about how where you install your programs or save your data matters, like in particular partitions or folders, is that just like hardcore min-maxing that's unnecessary for the average user that doesn't care to wait half a second extra or is it actually relevant? I'm just putting stuff in my Home folder.

Connected to the last two points: in that Linux Hardening Guide lemmy post I shared the TL;DR includes "Move as much activity outside the core maximum privilege OS as possible"... how do I do that? is that why people have separate partitions?

Downloaded the App Center (Snap Store) and I was surprised there was even a file saying to not allow it... why is that? Is it not recommended? Is it better to download stuff directly from their websites instead?

I would also add that the more you modify the system (PPAs, packages not installed via the package manager, nonstandard partition layouts) decreases the stability of your system and makes it harder to get back to your current system state if something goes wrong. I like to think about it like balancing a tower of blocks as a kid. Mint is the first block, and is very stable, but each additional block makes the system less and less stable. Mint itself is really stable, but if you do weird stuff the Mint devs can't do anything about it, which puts you in a bad position until you really know what you're doing.

The Snap store is intentionally left out by Mint, because they don't like how Ubuntu manages it. This means that even though the Ubuntu version Mint is based on supports Snap, there's no guarantee that snaps will work with the same stability which .deb/apt and flatpak packages will, because it hasn't been tested in Mint. I would advise against using it.
