What is Linux?

Linux is an open source operating system (OS). An operating system is the software that directly manages a system’s hardware and resources, like CPU, memory, and storage. The OS sits between applications and hardware and makes the connections between all of your software and the physical resources that do the work.

Wilma again

I have ongoing issues with the Linux Mint installation on the laptop I use for software development and blogging.

You may recall I tried upgrading to version 22 (code name: Wilma), encountered a graphics regression, and had to revert the upgrade using TimeShift. Since then, my Linux experience hasn't been quite right. While troubleshooting an issue, I uninstalled Python; this broke APT, causing routine software updates to fail.

Yesterday I created a new partition on the HDD and attempted a clean install of Wilma there. After several tries, I suspect that my largest USB thumb drive (NXT brand, purchased in January 2024) suffers from data corruption.

Believe it or not, my 2nd-largest thumb drive is too small to hold the 2.9 GByte ISO image, so this morning I'm off to buy a new thumb drive.

Seeking IT post

Sadly, the contract for @fordprfct has come to an end, and he has to find new work. (although 4 years for what was supposed to be a 1 year contract isn't bad - and they jumped through hoops to keep him when his former contracting company was rejected.) I've seen through his coworkers' reactions, he's VERY good at what he does. Jobhunting is much more unpleasant. He works remotely, and I'm hoping someone might know of an opening for him, so here's what he does. I can tell you, he picks up new software challenges like a cat going after tuna.

Hello, Xia!

Today I upgraded my Linux Mint desktop from Wilma (version 22) to Xia (version 22.1). The upgrade itself went very smoothly. After it was done, however, I decided to rename the mount point for my home directory ... because the old (autogenerated) name was ridiculously long and awkward.

The rename didn't go smoothly. I broke the Xia install so badly that I couldn't log in. Luckily I still have a bootable partition with Virginia (version 21.3) installed. I booted Virginia and used it to repair my mistake.

According to Wikipedia, "Xia" is a surname and the name of several dynasties. Unlike all the other Linux Mint codenames, it doesn't seem to be a feminine given name. I guess the release manager goofed!

Linux distros - what is the difference, which one should I choose?

Caution, VERY long post.

With more and more simmers looking into linux lately, I've been seeing the same questions over and over again: Which distro should I choose? Is distro xyz newbie-friendly? Does this program work on that distro?

So I thought I'd explain the concept of "distros" and clear some of that up.

What are the key differences between distros?

Linux distros are NOT different operating systems (they're all still linux!) and the differences between them aren't actually as big as you think.

Update philosophy: Some distros, like Ubuntu, (supposedly) focus more on stability than being up-to-date. These distros will release one big update once every year or every other year and they are thoroughly tested. However, because the updates are so huge, they inevitably tend to break stuff anyway. On the other end of the spectrum are so-called "rolling release" distros like Arch. They don't do big annual updates, but instead release smaller updates very frequently. They are what's called "bleeding edge" - if there is something new out there, they will be the first ones to get it. This can of course impact stability, but on the other hand, stuff gets improved and fixed very fast. Third, there are also "middle of the road" distros like Fedora, which kind of do... both. Fedora gets big version updates like Ubuntu, but they happen more frequently and are comparably smaller, thus being both stable and reasonably up-to-date.

Package manager: Different distros come with different package managers (APT on ubuntu, DNF on Fedora, etc.). Package managers keep track of all the installed programs on your PC and allow you to update/install/remove programs. You'll often work with the package manager in the terminal: For example, if you want to install lutris on Fedora, you'd type in "sudo dnf install lutris" ("sudo" stands for "super user do", it's the equivalent of administrator rights on Windows). Different package managers come with different pros and cons.

Core utilities and programs: 99% of distros use the same stuff in the background (you don’t even directly interact with it, e.g. background process managing). The 1% that do NOT use the same stuff are obscure distros like VoidLinux, Artix, Alpine, Gentoo, Devuan. If you are not a Linux expert, AVOID THOSE AT ALL COST.

Installation process: Some distros are easier to install than others. Arch is infamous for being a bit difficult to install, but at the same time, its documentation is unparalleled. If you have patience and good reading comprehension, installing arch would literally teach you all you ever need to know about Linux. If you want to go an easier and safer route for now, anything with an installer like Mint or Fedora would suit you better.

Community: Pick a distro with an active community and lots of good documentation! You’ll need help. If you are looking at derivatives (e.g. ZorinOS, which is based on Ubuntu which is based on Debian), ask yourself: Does this derivative give you enough benefits to potentially give up community support of the larger distro it is based on? Usually, the answer is no.

Okay, but what EDITION of this distro should I choose?

"Editions" or “spins” usually refer to variations of the same distro with different desktop environments. The three most common ones you should know are GNOME, KDE Plasma and Cinnamon.

GNOME's UI is more similar to MacOS,  but not exactly the same.

KDE Plasma looks and feels a lot like Windows' UI, but with more customization options.

Cinnamon is also pretty windows-y, but more restricted in terms of customization and generally deemed to be "stuck in 2010". 

Mint vs. Pop!_OS vs. Fedora

Currently, the most popular distros within the Sims community seem to be Mint and Fedora (and Pop!_OS to some extent). They are praised for being "beginner friendly". So what's the difference between them?

Both Mint and Pop!_OS are based on Ubuntu, whereas Fedora is a "standalone" upstream distro, meaning it is not based on another distro.

Personally, I recommend Fedora over Mint and Pop!_OS for several reasons. To name only a few:

I mentioned above that Ubuntu's update philosophy tends to break things once a big update rolls around every two years. Since both Mint and Pop!_OS are based on Ubuntu, they are also affected by this.

Ubuntu, Mint and Pop!_OS like to modify their stuff regularly for theming/branding purposes, but this ALSO tends to break things. It is apparently so bad that there is an initiative to stop this.

Pop!_OS uses the GNOME desktop environment, which I would not recommend if you are switching from Windows. Mint offers Cinnamon, which is visually and technically outdated (they use the x11 windowing system standard from 1984), but still beloved by a lot of people. Fedora offers the more modern KDE Plasma.

Personal observation: Most simmers I've encountered who had severe issues with setting up Linux went with an Ubuntu-based distro. There's just something about it that's fucked up, man.

And this doesn't even get into the whole Snaps vs. Flatpak controvery, but I will skip this for brevity.

Does SimPE (or any other program) work on this distro?

If it works on Fedora, then it works on Mint/Ubuntu/Arch/etc., and vice versa. This is all just a question of having the necessary dependencies installed and installing the program itself properly. Some distros may have certain prerequisites pre-installed, while others don't, but you can always just install those yourself. Like I said, different distros are NOT different operating systems. It's all still Linux and you can ultimately customize it however you want.

In short: Yeah, all Sims 2-related programs work. Yes, ReShade too. It ultimately doesn't really matter what distro you use as long as it is not part of the obscure 1% I mentioned above.

A little piece of advice

Whatever distro you end up choosing: get used to googling stuff and practice reading comprehension! There are numerous forums, discord servers and subreddits where you can ask people for help. Generally speaking, the linux community is very open to helping newbies. HOWEVER, they are not as tolerant to nagging and laziness as the Sims community tends to be. Show initiative, use google search & common sense, try things out before screaming for help and be detailed and respectful when explaining your problems. They appreciate that. Also, use the arch wiki even if you do not use Arch Linux – most of it is applicable to other distros as well.
