1,024 is \textit{not} a thousand, and 1,048,576 is \textit{not} a million. For my entire life, we've just walked right past this and pretended that we didn't notice. Doing science stuff? \textit{kilo} is a 1,000 and \textit{mega} is a million. Doing computer stuff? Then \textit{kilo} means 1,000\textit{ish} and \textit{mega} means a million\textit{ish}. Move along now, nothing to see here.
That discrepancy should bug you. It bugs me, but I also have bills to pay, so when someone asks ``\textit{how much} does it bug you?'' my honest answer is that I've worked hard to not let it bug me all that much.

Unfortunately, when you bought a computer in those days you got exactly that in the box: a computer. There was no monitor, there was no disk drive, there was no printer. You just got a computer in a box with a power supply. I had scrimped and saved forever to buy this, and had fortunately also managed to save enough for a monitor, which in those days was a big, heavy cathode-ray tube device (CRT, for short). One of the selling points of the C-64 was that it was portable. You could just pick it up and take it with you. (It seems like all computers in the movies back in the day either took up entire rooms or buildings---think Hal-9000 in \textit{2001: A Space Odyssey}---or were something you could carry in your hand---think the tricorders in \textit{Star Trek}. We've never managed a happy medium.) The monitor, however, was anything \textit{but} portable. It was heavy, it was bulky, and it was fragile. Slam a lid closed on a modern laptop and everything will probably be fine. Knock a CRT off the table and it's toast. If it lands on your foot, you'll probably end up in the emergency room.

The second computer I ever owned was a Commodore 128. Whereas its predecessor only had 64 kb of memory, the C-128, as we called it, had a whopping 128 kb of memory—twice the memory for nearly the same price. While the C-64 could only run in the 1 Mhz\footnote{megahertz—a measure of a computer's computing speed} mode, the C-128 could run in 1 Mhz mode or 2 Mhz mode, but such were the demands on its resources that running in 2 Mhz mode meant the screen would go blank—it simply didn't have the power to process that fast and display that processing on the screen at the same time. For comparison, I just pulled up a cheap Lenovo laptop on Best Buy's website that has an Intel i3 processor with 8 GB of memory and a 256 GB solid state drive and is on sale for \$389. It has a clock speed of three \textit{gigahertz}.

Unlike the C-64, which was round and bulky, the C-128 was slim and sleek. In fact, one of its selling points was its portability, and I recall seeing a brochure where a college student is walking around campus with one under his arm. What they left out of that illustration, of course, is his friend dragging a little red wagon with a terribly heavy CRT monitor in it, along with an incredibly heavy power source. They were portable in theory, but not in any practical manner. But compared to a mainframe that took up an entire room or building, it was light years ahead of its time. And I \textit{felt} like that, too, like this computer was going to take me places where I would be light years ahead of where I was then.\footnote{It didn't, because you need so much more than just a computer to get ahead. You need resources, you need people who believe in what you're doing and support you, and you need people who can point you in the direction of the next step. If you don't have those things, you're not a visionary with a bright future ahead of him, you're just a nerd with a computer.}

Like I said, the laptop I am using now has 8 GB of memory, which is a lot more than 128 kb of memory. But how much more? It's difficult for most people to visualize numbers, especially when they are orders of magnitude apart, and looking at raw numbers doesn't give our brains much to latch onto. We need to \textit{visualize} these numbers, which is why I used money earlier. But because I like math and most people like food, let's visualize these numbers a different way: through food.\footnote{A\&W once tried to launch a $\nicefrac{1}{3}$ pound burger to compete with McDonald's quarter-pounder, the idea being you get more meat for the same price. But it didn't sell because people thought a third of a pound was less than a fourth of a pound. (Again, the metric system for the fucking win.) They could get $4>3$, but they couldn't understand $\nicefrac{1}{4}<\nicefrac{1}{3}$.

Now it's the other way around: technology manipulates you and you \textbf{can't} shut it off. Websites (I'm thinking of Amazon here, as they are the best at it, but plenty of other websites do this as well) now \textit{tell} you what you want to buy. You can buy things on subscription so that you don't have to think any more.\footnote{It can be devilishly tricky to actually unsubscribe from some of these things, to the point where it's easier just to absorb the expense (we can always get the kids vaccinated \textit{next} year) and just decide that this is how we live now.} Streaming services control what you watch or listen to. No longer can you just walk into a record store or a video store and get what you actually want. No longer will people experience the serendipity of walking into a store and finding a movie or album that becomes a huge part of their life. (I've discovered some of my favorite books that way. I truly believe certain objects just call to you.\footnote{I know that's kind of woo-woo, and I am not into a lot of woo-woo stuff.

You can also execute bash scripts as well. In addition to a local backup on an external drive, I also backup the directories in my home drive to a remote storage location. To make life easy, I created a script (called, naturally, \texttt{backup.sh}) in each of those directories to back them up. To execute those backup scripts, I just need to go to that directory, open the directory in a terminal and type \texttt{./backup.sh}.
The problem here is that a lot of times, I'm not even in those directories when I'm saving files to them. I'm somewhere else. And to open the directory in my GUI and then open it in a terminal, or to open a terminal and then navigate to that directory, is a little \textit{too} much when I want to run that backup script.

Second, these words are highly contextual. What does ``beginner'' even mean? Someone who's just sat down to a computer for the first time in their life? Or someone who's been working on computers since they were ten years old, but are just now beginning to learn LaTeX? These words are easier to define in other areas, such as sports or music, where you have to learn to skate before you can play hockey, and you have to learn scales and chords before you can play music.\footnote{Although I am not an expert in either of these things, and maybe it is possible to learn hockey and music without learning how to skate or learning scales and chords first.

Third, people may self-select out of things.

But I can't think of a better phrase.} They were \textit{occassionally} intimidated by certain things, but for the most part, they were eager to learn as much as they could.

The class was extremely inexpensive, but it was rarely ever full, which made me wonder why more people didn't take this class. There are two answers here. First, this was the early 90s and a lot of people didn't even have computers at home, so what would be the point for them? (You don't need a car if you have no place to go.) Second, a lot of people were terribly intimidated by computers, because they thought you had to be really smart to use them. So they self-selected out of something they were perfectly capable of learning because they thought it was too advanced for them.\footnote{People are really afraid of making mistakes and looking stupid, but that's a by-product of our public education industrial complex. You can't learn \textit{anything} without making mistakes. In fact, people who are truly experts about things often point out that they learn as much or more from their mistakes than they do from their successes. But we have turned making mistakes into something to be ashamed of, rather than something which will help us learn and understand things. Fuck that attitude. Go forth and make mistakes.

I've been with Ubuntu for a while now, and generally get pretty excited about new releases. Ubuntu 22.04 was no different. Until I installed it, that is.

First, they have removed Python2. If you have any applications which depend on Python2, such as PDF Booklet,\footnote{Which is what I use to make the physical form of this zine. See \href{https://pdfbooklet.sourceforge.io/wordpress/}{\texttt{https://pdfbooklet.so\\urceforge.io/wordpress/}} for more information.} those tools are now unusable. And despite numerous attempts to reinstall Python2 just to make this one app work, I have thus far been unsuccessful.
Second, there is this weird problem with saving files from \textit{any} browser. You can pick a folder to download to, and from that point on in your session, this is the only folder you can download items to. Sure, you can migrate to a different folder and try to download there, and it looks like you're actually saving your file there, but nothing gets downloaded. You can look at the folder and at your download history and quite plainly see that there is nothing there.\footnote{See \href{https://askubuntu.com/questions/1406265/ubuntu-22-04-firefox-does-not-download-file-to-desktop}{\texttt{https://askubuntu.com/questions/1406265/ubuntu-22-04-firefox-does-not-download-file-to-desktop}} and \href{https://askubuntu.com/questions/1406674/cant-download-files-after-upgrade-to-22-04}{\texttt{https://askubuntu.com/questions/1406674/cant-download-files-after-upgrade-to-22-04}}} As it turns out, if you click on the \textit{filename} in the save dialogue box (and therefore give it focus), then you can change where you download the file to.
This is an odd bug to allow to get through, as for the longest time the question ``What does everyone use Internet Explorer for?'' was answered by ``To download Firefox.'' I guess you can always use Ubuntu to download a version of Linux which is not plagued by such obvious mistakes.

Third, the default video player (Totem) cannot play .mp4 files.\footnote{See \href{https://askubuntu.com/questions/1406254/after-installing-ubuntu-22-04-the-default-video-player-is-unable-to-play-any-vi}{\texttt{https://askubuntu.com/questions/1406254/after-installing-ubuntu-22-04-the-default-video-player-is-unable-to-play-any-vi}}.} Yes, I know that .mp4 is not strictly open source (as some of the codecs are patented) and I also know that you can install these codecs with \texttt{\$ sudo apt install ubuntu-restricted-extras}, but if you have a phone, or a video camera, they probably record video as .mp4 files, and it would be nice if you could see view them on your computer.
Fourth, the new screen capture tool in the Gnome desktop is an absolute disaster. It requires you to go through a ``screenshot portal'' each and every time you create a screenshot, \textit{regardless} of which screenshot tool you use. It's ridiculous, as I (and many other users) already had a workflow for screenshots, and this is not acceptable in an open-source operating system (which actually makes me wonder how ``open-source'' open-source software actually is). Of course, people are upset, because this is a solution in search of a problem to solve. I have no idea why \textit{anybody} thought this was a good feature to include. And of course, the developers have closed off any discussion of this topic.\footnote{See \href{https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/1970}{\texttt{https://gitlab.gnome.org/GNOME/gnome-shell/-/merge\_requests/1970}}, \href{https://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4895}{\texttt{https \\://gitlab.gnome.org/GNOME/gnome-shell/-/issues/4895}}, and \href{https://github.com/flatpak/xdg-desktop-portal/issues/649}{\texttt{https://github.com/fl \\ atpak/xdg-desktop-portal/issues/649}}.} Listen, if people complain, you should listen to them.
