\section{College, 1986}
\subsection{1986}
I went away to college in the fall of 1986. Personal computers were, as always, very much on my mind, but I still only owned a Commodore 128. We were still typing papers on electric typewriters at that point, and the height of that technology was correction paper.\footnote{This was a very convenient alternative to a product called "Liquid Paper" (also called "whiteout") which was essentially paper-colored paint in a small bottle with a brush in the cap. When you made a mistake, you shook the bottle and brushed a very thin layer over the mistake. You then waited for the whiteout to dry, backed up, and typed the correct letter. The fluid contained a lot of solvent, and as this was the time of the Satanic Panic, parents were warned that their kids could be huffing whiteout. As you used the product, more and more of the solvent evaporated out of the bottle, until it eventually became a gloopy, chalky mess, meaning you could only use half of what was in the bottle—it was not very efficient. With correction paper, you just backed up to the mistake, put a bit of correction paper on top of the paper, typed the mistake again, removed the correction paper, backed up, and typed the correct letter. It was much neater, had no terrible fumes, and you didn't have Fundies chasing you down the street accusing you of being a devil-worshiping drug addict because you had a bottle of correction fluid in your pocket. (Liquid Paper was invented by Bette Nesmith Graham, who also happened to be the mother of Mike Nesmith of the Monkees. The world is much smaller than we think it is.)}

We did have computers available to us, however. Our college owned two mainframe systems: a DEC-10 and a VAX 9000. As I remember, you had to go down to the basement of the science building to use them, where they had a room filled with VT100 terminals.
I wish for the life of me that I could remember this experience better. The ``computer room '' (nobody thought of it as a ``lab''—it would be many years before I heard that term applied to it) looked a lot like what one might think: a windowless basement room with concrete block walls, tile floors, fluorescent lights buzzing away angrily overhead, and lots and lots of terminals.\footnote{There is a pdf of the VT100 manual available at \href{https://vt100.net/dec/ek-vt100-tm-002.pdf}{\texttt{https://vt100.net/dec/ek-vt100-tm-002.pdf}}.

People didn't really know much about these two mainframe systems, although I remember hearing the few computer people who were around praising the VAX as being far superior to the DEC-10.\footnote{A bit of internet research confirms this—the VAX line of mainframes was intended as a replacement for the DEC line of mainframes.} Everything was from the command line. If you saved a file\footnote{I tried for a few weeks to type up some of my notes from class, but quickly realized that this was pointless, as I couldn't take the digital files with me.} and wanted to print it, you had to send it to the print queue, and then go to a different room in the building where the line printer was located.
At this point, it was possible that your printout was ready. But it was also entirely possible that it wouldn't be ready. Everything was printed on unperforated continuous feed paper that was 15 inches wide.\footnote{See the Wikipedia entry on ``'continuous stationery'' to see what I'm talking about.} The problem was someone had to be there to tear off your printout after it was completed—the printers had no way of doing this automatically—take it out of the printer's tray, figure out that it belonged to you, label it with your name, and set it on a shelf for you to pick up later.

And if nobody was there, the printer just kept printing, and someone would have to separate possibly dozens of different print jobs. If your print job was small, it was entirely possible that the person responsible would miss it and it would end up stuck on the end of someone else's print job. If the printer ran out of paper and nobody was there to replace it, your file just went into the printer memory (or somewhere into the ether if the printer's memory was full) until the paper was refilled. Printing anything was a big investment of time and energy (not to mention hope) and I will gladly take the occasional printer jam over that experience any day.

The only other remarkable thing I remember about that early college experience is that everybody had to take a basic computer course. This was a single, university-level course that all freshmen had to take.

I hate these sorts of things.
I get the point—computers are going to be a thing in everybody's lives, so lets make sure all our future graduates have a solid background in them. The problem is that information technology moves at a pretty rapid pace, and college students have a wide variety of backgrounds and career plans, and as a result, it's difficult to create a course like this that is in any way useful to every single student who takes it.
And I found that I knew much of the material anyway. It was held in a large lecture hall, and there wasn't really any point for the instructor to hold up a hard drive in her hand and announce ``This is a hard drive''—unless you were in the first ten rows, she could have been holding up a brick. I'm sure that what she said after that sentence was informative, but I'm also sure I already knew it.

Sometime during the third week we had an entire lecture about modems (``\textit{modem} stands for \textit{modulator-demodulator}'' I remember hearing before I dozed off\footnote{Which is true, but means absolutely nothing to anyone who just wants to get on the internet. Modems were designed to transmit digital data over analog telephone lines, and they accomplished this by \textit{modulating} a carrier wave to carry digital information before sending it, and \textit{demodulating} a received carrier wave to recreate the original digital information. I don't miss 4,800 bps speeds, but I do miss that modem login sound. Apparently other people do as well, because you can hear it at \href{https://www.youtube.com/watch?v=gsNaR6FRuO0}{\texttt{https://www.youtube.com/watch?v=gsNaR6FRuO0}}}) and I decided to just stop attending class. I showed up for the exams, rushed through them, got a C in the course, and decided to never take another computer course ever again.
I should mention that I went to college with the goal of becoming high school biology teacher. Over time, I realized how valuable this computer course was to me, because it made me realize that no matter who you are or where you are in life, any class should be valuable to you in some way. (This is a lesson that the modern educational-industrial complex has not, and will never, absorb.)

\section{Teaching Computers}
I graduated from college with a B.S. in Biology and a teaching certificate. I could not find a job teaching biology—as it turns out, biology teachers are a dime a dozen\footnote{This was a huge surprise to me, because all through college, whenever I told someone I was a biology major, they seemed really impressed and said something like "oh gosh, biology—that's really hard." But note—these were non-science people. If you want to study science, but don't want anything too hard, apparently biology is the default.} and chemistry teachers are about ten bucks a dozen, and if you majored in physics with a goal of teaching high school science, you would have your choice of any teaching position you wanted.

Of course at this time (the early 90s), lots of people still wanted to be teachers, unlike now, because teachers still garnered respect from the public, parents, and administrators, and teaching jobs were hard to come by, also unlike now. So I started substitute teaching and doing whatever I could to pay the bills.

So I started substitute teaching and doing whatever I could to pay the bills.
I eventually managed to find a job at my old high school teaching what used to be called ``night school''\footnote{I have no idea what this is now called, or if it is even still a thing.} and what is still called ``community education''. But names are only labels and are usually irrelevant. My night school students had dropped out of a traditional high school education and were now in search of a GED\footnote{General Equivalency Degree—aka ``high school diploma in a box''.} to help their job prospects. I was there to teach them just enough Earth Science to enable them to pass the science portion of the GED exam.\footnote{There is so much that I could say here, but it is completely irrelevant to our current purpose and so belongs to an entirely different zine.}

This meant that telling someone how to print a file meant that I ended up saying something like ``move your mouse\footnote{i.e., cursor. To someone who is new to computers, the two are one.} to the upper left-hand corner, find the `File' menu and click on it, and then go about half way down until you see the word `Print' and click on it.''
And this worked. My students were not familiar with a ``File'' menu, but they were familiar with the concepts of ``up,'' ``down,'' ``right,'' and ``left''. This led me to realize something that I had not been taught in college—you have to work with students where they are, rather than where you wish they were. You can't play the ``if only'' game. (``If only my students knew where the File menu is…'')

It's a symbol font, so when it comes to music, what it offers is rudimentary: you can add an eighth note (\eighthnote), a quarter note (\quarternote), a half note (\halfnote), a whole note (\fullnote), or two joined eighth notes (\twonotes). In math mode, you can also add a natural symbol ($\natural$), a flat symbol ($\flat$), or a sharp symbol ($\sharp$).

\LaTeX{} has a couple of different environments that are useful for typesetting math (\texttt{align} and \texttt{array}, but they get a little beyond what I want to cover here.\footnote{Maybe in a later issue?

We are in Late Stage Capitalism. That is, we have reached a stage of capitalism which is unsustainable on this planet alone. The entire point of capitalism is ``growth'' but when you are limited to an existence on a single planet that has no trade with other planets, that growth is limited by the amount of whatever resources that planet has. And when those resources run out—or it becomes impossible to make a profit by exploiting them—capitalism will collapse, and it will very like take billions of us with it.

These resources have always been \textit{physical} resources—food, wood, coal, oil, rare-earth elements, and the labor of the working classes to extract and process them.
Because those resources are finite, we've seen capitalism go off in other directions to find other resources to exploit. This explains why rich white guys with entirely too much time on their hands want to ride their penis-rockets into space—because asteroids are out there and they're just full of iron, cobalt, and other metals just waiting to be mined.

This explains why rich white guys with entirely too much time on their hands want to ride their penis-rockets into space—because asteroids are out there and they're just full of iron, cobalt, and other metals just waiting to be mined and turned into cell phones.
But we've also seen capitalism go in a hitherto new direction: the digital direction. Capitalism is no longer interested in just mining iron or coal; it's also interested in mining \textit{data}. Data, it seems, is the one resource we can never run out of.\footnote{When I worked in retail, I was always told to push the extended warranties whenever I could. This was partly because the profit margin on them was incredibly high (extended warranties are basically a legal scam because there are so many terms and conditions you'll never be able to cash in) and ``they're the one inventory item we never run out of.''}
The primary kind of data they want is information about what we are interested in: what we want to buy, because if they know what we are interested in, they can then sell that information to advertising platforms who will slug your user experience full of advertisements for those exact things.

As a result, when you think ``I could really go for a sandwich right about now'' you automatically think of the nearest Evil International Sandwich Shop and not the local mom-and-pop sandwich shop, simply because you saw an ad for the EISS, and when it comes to both hunger and money, your big huge mammalian brain depends on that little tiny reptilian bit at its core.

As I write this, the release of Ubuntu 24.04 is less than a year away. Unlike the release of Ubuntu 22.04, I am not in the least bit excited. And I will \textbf{not} be upgrading immediately, if at all. (Ubuntu 22.04 has ten years of security releases,\footnote{See \href{https://ubuntu.com/about/release-cycle}{\texttt{https://ubuntu.com/about/release-cycle}} for more information.} so I will be good for a while.)
I do have a spare machine that I can experiment with Ubuntu 24.04 on. The main problem is that I don't have a lot of time.\footnote{If I did, you'd be reading issue \#12 of this zine, rather than issue \#3.} So yeah, I can install Ubuntu 24.04 and ooh and aah over whatever is new and shiny (and I admit, ``new and shiny'' was a big part of the reason I was so eager to update to 22.04---I'm a human and our eyes are quite naturally drawn to ``new and shiny''). But I don't have the needed time to fully experiment with it and determine if it is suitable to my needs (which range from ``needs to be perfect'' to ``needs to be just the right amount of shitty'') or if it's another disaster-in-waiting.

This is a problem because that \texttt{paper\_cutter.jpg} image is 136kb in size and that \texttt{c128.jpg} image is 2.3 mb in size. Because these get included in \LaTeX{}, which then handles the scaling, the resulting pdf file is rather bloated, which is the exact opposite of what you want when you are distributing something via the internet.
Because I am scaling the paper cutter image by 0.5, the resulting file size should be about a fourth of that, or 34 kb.

\section{What I learned About \LaTeX{} While Creating Something Else}
For reasons I don't understand I went down an internet rabbit hole reading about the book \textit{Flatland}, by Edwin A. Abbott. This is a book I had purchased years ago in my youth (thank you, Dover Thrift Editions!) but had never gotten around to reading. I found a copy in \LaTeX{} at \href{https://github.com/Ivesvdf/flatland}{\texttt{https://github.com/Ivesvdf/flatland}}. It was old---twelve years old, in fact---and it was set up as a single-sided A4 document. If you've been following this journey this far, you know that I'm pretty fond of booklets, and that I'm in North America, so everything has to be lettersize paper.\footnote{As an American citizen, I am bound by the U.S. Constitution to both completely disavow the metric system and be utterly confused by it, and to decry it as terribly confusing despite the fact that is based on dividing and multiplying by the number 10. This is part of our constitutional duty to vehemently oppose anything which makes sense and also makes life better, such as universal health care. I don't know, something about eagles and gravy and guns.}

\LaTeX{} was designed to write documents; as such, its ability to fine-tune certain document parameters, such as line-spacing, is fairly limited out of the box.\footnote{As it should be! Remember, the Unix Principle is to do one thing and do it well, not to be a Swiss army knife.} But if you need something, chances are that someone else has needed it before you and created a package that will do just that.
