Proposal: A New Standard for Encloseable Small Computers

Jan 16th, 2021

Monitors are getting big. Computers are getting small. I think I’ve mentioned this idea before: a cavity in a monitor big enough to hold a Raspberry Pi, with the monitor providing power, video display, and a couple of USB ports for connecting peripherals like mice, keyboards, and thumb drives. Several of my Dell monitors have a coaxial power jack intended for speaker bars, and a USB hub as well. I’ve opened up a couple of those monitors to replace bad electrolytics, and as with most computer hardware, a lot of that internal volume is dead space.

The idea of a display with an internal computer has long been realized in TVs, many of which come with Android computers inside. That said, I’ve found them more a nuisance than useful, especially since I can’t inspect and don’t control the software. These days I outsource TV computing to a Windows 10 Intel NUC sitting on the TV cabinet behind the TV.

The top model of the Raspberry Pi 4, with 8 GB RAM, is basically as powerful as a lot of intermediate desktops, with more than enough crunch for typical office work; Web, word processing, spreadsheets, etc. With the Debian-based Raspberry Pi OS (formerly Raspbian) and its suite of open-source applications, you’ve got a desktop PC. More recently, the company has released the Raspberry Pi 400, which is a custom 4GB RPi 4 built into a keyboard, with I/O brought out the back edge. (In truth, I’d rather have it built into a display, as I am extremely fussy about my keyboards.) Computers within keyboards have a long history, going back to (I think) the now-forgotten Sol-20 or perhaps the Exidy Sorcerer. (Both appeared in 1978.)

What I want is breadth, which means the ability to install any of the modern small single-board computers, like the Beaglebone and its many peers. Breadth requires standardization, both in the monitor and in the computer. And if a standard existed, it could be implemented in monitors, keyboards, printers, standalone cases, robot chassis, and anything else that might be useful with a tiny computer in its tummy.

A standard would require both physical and electrical elements. Electrical design would be necessary to bring video, networking, and USB outside the enclosure, whatever the enclosure is. (I reject the bottom-feeder option of just leaving a hole in the back of the enclosure to bring out conventional cables.) This means the boards themselves would have to be designed to mate with the enclosure. What I’m envisioning is something with a card slot in it, and a slot spec for video, network, i2s, and USB connections. (GPIO might not be available through the slot.) The boards themselves would have slot connectors along one edge, designed to the standard. The redesigned boards could be smaller and thinner (and cheaper) without the need for conventional video, network, audio, and USB jacks. (Network connectors are increasingly unnecessary now that many boards have on-board WiFi and Bluetooth antennas.) Picture something like the Raspberry Pi Zero with edge connectors for I/O.

Defining such a standard would be a minor exercise in electrical engineering. The big challenge would be getting a standards body like ANSI interested in adopting it. The Raspberry Pi Foundation has the engineering chops, obviously, and once a standard has been created and proven out, groups like IEEE or ANSI might be more inclined to adopt it and make it “official.”

I understand that this might “fork” the small-board computing market between GPIO boards and non-GPIO boards. Leaving the GPIO pads on the opposite edge of the board is of course possible, and would allow the board to be enclosed or out in the open, or inside some other sort of enclosure that leaves room for GPIO connections. A big part of the draw of the small boards is the ability to add hardware functionality in a “hat” that plugs into the GPIO bus, and I don’t want to minimize that. I think that there’s a market for non-GPIO boards that vanish inside some larger device or enclosure that provides jacks for connections to the outside world. The Raspberry Pi 400 is an excellent example of this, with GPIO header access as well. What I’m proposing is a standard that would allow a single enclosure device to be available to any board designed to the standard.

Ok, it would be hard–for small values of hard. That doesn’t mean it wouldn’t be well worth doing.

The Question That Nobody’s Asking

Jan 13th, 2021
by Jeff Duntemann.
28 comments

I’ve been scratching my head a lot lately, and I need to stop before I wear through my scalp. (My natural armor has been mostly gone for thirty-five years.) It’s a natural, nay obvious question, which I’m putting in bold and giving its own paragraph:

If masks prevent SARS-CoV-2 infections, where did the current explosion of cases and deaths come from?

Take a look at the screenshot below. This is from the Arizona Department of Health Services’ COVID-19 dashboard. The graph is deaths by date of death for the entire state of Arizona. The curve starts heading toward the sky during the last week in October.

AZCovidDeathsGraph-500 wide.png

Maricopa County, where we live, issued a mask mandate on June 19, 2020. That was right about when the first near-vertical slope in the graph began. It took a few weeks for the mandate to catch on, but by August 1, it was pretty much universal. That’s about when the curve started to fall. There was a certain amount of crowing that the mask mandate had brought the pandemic under control in the state.

Then the end of October happened.

Now, I’ve been watching not only whether people are wearing masks in retail outlets and offices (they are) but also what kinds of masks and how they’re being worn. Over time, the masks are getting better. I’m actually seeing KN95 masks with some frequency, and it’s been a couple of weeks since I’ve seen a useless “train robber” bandana mask anywhere. Mask adherence in the state is at 90%, which aligns with what I’ve seen, if perhaps on the low side. That’s a mighty high rate.

So again, my question: With mask adherence at 90%, why is the curve still so high? Note that the graph is of the days deaths happen, not when they are reported. Death reports are not all received by the state on the days deaths happen, and reports from rural areas can take a week or more to get to AzDHS. What looks like a falling curve at the right edge of the graph may simply be due to lag time in reporting.

There is certainly some inflation of death counts due to the problem of “with COVID but not of COVID.” Some. I don’t think that kind of confusion can cause the numbers we’re seeing here. And it’s inevitable that a certain amount of fraud happens; I’ve seen the news stories describing gunshot suicides, car accidents, and victims of alcohol poisoning described as COVID-19 deaths–some without a positive test for the virus. However, if there had been enough fraud to cause this explosion in deaths, somebody somewhere would have said something.

Wouldn’t they?

Ok. Although I’m open to other theories, I think it’s significant that something happened in the last week of October: Arizona temperatures crashed hard. We had a long, lingering summer here. Mid-October was still giving us 90+ degree days. That went down into the 60s and 70s in a big hurry.

It’s long been known that viral respiratory diseases become much more prevalent in cold weather. Why this should happen isn’t known with certainty. One theory is that influenza and corona viruses have a coating that becomes more rugged in colder temps, giving the virus a longer survival time in air and even in sun. Dry weather favors viruses for reasons that, again, are far from clear.

Well, in Arizona we have dry weather in spades, year-round. Cold, not so much. In fact, a typical winter’s day here is probably about the same temp as a typical summer’s day in North Dakota. Given the uncertainty about what causes viruses to infect more readily in winter, could it be a conjunction of cooler (than usual) temps and extreme dryness? Or (and I like this one better) is there something about the effect of a fall in temperatures (the delta, not the absolute temps) on the human body that gives the virus free rein?

That’s the only theory I have that I haven’t already shot down. It wasn’t Thanksgiving gatherings; the curve took off close to a month before Thanksgiving. And for all that, I consider it pretty thin gruel. It’s dry here probably 340 days a year. It’s even drier in summer than winter.

The theory that people spend more time indoors than outdoors in winter doesn’t apply in Arizona. The reverse is largely the case: When it’s 110 degrees outside, most people stay indoors, or maybe stand up to their necks in the pool. Winter is when people jog, bike, hike, and work outdoors, getting lots of fresh air and plenty of sun (and thus crucial Vitamin D) on their faces, arms, and legs.

Again, where the hell did that near-vertical runup in deaths come from?

I’ll tell you where it didn’t come from: People ditching their masks. The fact that mask compliance is at 90+% during an explosion in COVID-19 deaths screams out something a lot of people don’t want to hear: Masks don’t prevent infection. If they did, the increase would have been a lot more gradual, and probably a lot lower in magnitude.

Let me put it in short, simple words: Masks have been sold as a means of stopping the spread of SARS-CoV-2. They’ve been sold hard. Mask skeptics get called a whole lot of dirty words, even though we wear masks as a courtesy to the rule of law. Faced with a graph like the one the State of Arizona itself puts out, what are we supposed to think?

The graph says something else, perhaps a little more quietly: There are no COVID-19 experts. We still have very little understanding of how this thing spreads and (especially) why it hits some people so devastatingly hard, and others barely at all. When our (often self-appointed) experts told us to put on masks, we put on masks. And then the graph went through the roof.

I wish I had answers. I don’t. Why two peaks instead of one? What had been going on between the end of July and the end of September? Were we doing something right? If so, what? And what did we start doing wrong in late October?

Nobody knows. Read that again: Nobody knows.

If I figure it out, you’ll read about it here.

Just-So Stories

Jan 12th, 2021
by Jeff Duntemann.
No comments yet

Here come the just-so stories. I ran into one some weeks ago that reminded me of the category. Most people think of Just-So stories as fables about animals, as Kipling wrote, especially fables about animal origins; e.g., how the leopard got his spots.

But that’s mostly because of Kipling. Wiktionary’s definition of a just-so story is “a story that cannot be proven or disproven, used as an explanation of a current state of affairs.” In most cases that’s true. In broader and more modern terms, a just-so story is an urban legend with a moral admonishing people to obey some stated principle or face the (scary) consequences. You’ve all probably seen your share, though you probably didn’t think of them as “just-so stories.” Still, that’s what they are.

Here’s the story I heard: A woman described having some unstated number of people over for Thanksgiving dinner. It was held outside, in Arizona. Some (unstated number) wore masks. The 13 others did not. The people who wore masks did not catch SARS-CoV-2. All the rest did.

I assume she thought she was doing a public service by frightening people into wearing masks all the time, everywhere. I don’t think she was ready for the response she got: People called her a fake, a yarn-spinner…a liar. The reason is fairly simple: The story is too pat. All the people who refused to wear masks got sick. None of the people who did wear masks got sick. And this was during a dinner held outdoors.

Is this possible? Of course. Is it likely? No, if you know anything at all about COVID-19. Was the dinner indoors? No. Were the dinner guests all older people? No. (The older people wore masks.) Young people may test positive for the virus, but they rarely show symptoms and almost never become seriously ill. And with even the slightest breeze, exhaled viruses are dispersed in seconds.

Yet, it was…just so. Medical privacy laws make such stories conveniently unverifiable.

I don’t want to pile on her too hard here, and thus won’t post a link. (I also don’t want to give her any more exposure than she’s already gotten.) The point I’m making is that urban legends are still very much with us, and unverifiable stories should be treated as such: useless at best and misleading at worst. The best way to fight urban legends is not to spread them. The second-best way is to (politely) state in the comments (if there is a comments section) that the story is an urban legend and not be trusted. The story may well have been “just so” in the teller’s imagination. In the real world, well…probably not.

  • I’ve mentioned this before in several places, but I will mention it again here and probably more than once again before it happens: On December 21, Jupiter and Saturn will be only one tenth of a degree apart. That’s one fifth the diameter of the full Moon. I’ve never seen two planets that close, and I’ve been looking at the sky now for 63 years.
  • As I mentioned in a recent entry, I’m putting my big 10″ Newtonian scope back together for the first time in close to 20 years. Most of the work lay in building a new base. (Termites ate the original, which I cobbled together out of scrap wood when I was 16.) The base is finished. The rest should be easy. With some luck I’ll get it all together and do a star test tonight. If my stars are in alignment, it’ll work. But hey, all stars are my stars, so I can’t lose!
  • While listening to Peter Hollens songs on YouTube, I stumbled across a remarkable women’s vocal ensemble: Brigham Young University’s Noteworthy. They’ve posted a number of videos, and all of them are amazing in terms of pure vocal harmony. Nothing I’ve seen tops their cover of “When You Believe” from the animated film Prince of Egypt. It’s the best song out of a very good bunch, and those ladies nailed it for all time.
  • I suspect that by now you’ve probably heard, but SF legend and former Analog editor Ben Bova died on November 30, of COVID-19 complications. He was 88. Ben taught for a week when I attended Clarion East 1973, and he was spectacular.
  • And as though that weren’t bad enough, Chuck Yaeger died this past Monday, December 7. Yaeger, to me, almost defines the word “badass.” He shot down 13 German warcraft during WW2, five of them on one mission. He rode the Bell X-1 to the sound barrier and beyond, and piloted the X-15 to the edge of space. He fought Death to a draw that lasted 97 years. Godspeed, General Yaeger.

RIP BEA

Dec 2nd, 2020
by Jeff Duntemann.

BookExpo America (BEA) and BookCon are folding. The shows’ organizers are blaming the shutdown on SARS-CoV-2, but the mask slips a little when they add, “The pandemic arrived at a time in the life cycle of BookExpo and BookCon where we were already examining the restructure of our events to best meet our community’s needs.” That’s corporate doubletalk for “The shows were both in trouble before the virus, and the virus was a plausible excuse to shut them down.”
I used to go to BEA every year. (I’ve never been to BookCon, which is a sort of combined fan and publisher gathering in NYC, targeted at consumers and mostly about fiction.) BEA was useful in a number of ways, not least of which was to see how our competitors were doing in the ’90s. I kept going for a few years after Coriolis folded, just to keep a finger on the pulse of the industry and spot trends. That pulse has been harder and harder to find in recent years. Ginormous publishing conglomerates are merging. This generally means that the smaller one is in trouble, and the bigger one wants their cash flow. Penguin Random House is buying Simon & Schuster, assuming antitrust challenges don’t emerge. What used to be The Big 5 is about to become The Big 4.
Two (related) things seem to me as behind publisher consolidation and the loss of big trade shows like BEA:
  1. The large publishers never wanted ebooks and don’t know how to deal with them.
  2. Independent publishing (indie) is catching on in a very big way.

The business model of traditional book publishing is complex, and weird. (Weird, even to me, and I worked in it for fifteen years.) The biggest single problem is that large and very large presses are fixated on hardcovers. This fixation goes back a very long way, and cooks down to the notion that hardcovers are books, and everything else (primarily ebooks and paperbacks) are secondary markets that depend on hardcovers to exist at all. It’s true that if you go back to the 1800s, vitually all books were hardcovers. Granted, there are exceptions: I have a paperback edition of Oliver Twist from 1882, which indicates that cheap books on cheap paper were there in the shadows all along, but were all too often slandered as “dime novels” that corrupted young minds. The money and prestige were in hardcovers.

Paperback originals emerged as a force in the 1950s, roughly concurrent with the emergence of the mass-market paperback (MMPB.) Because early MMPBs were reprints of hardcover editions, the notion of paperbacks as a secondary market was logical. When paperback originals emerged, larger presses used them to build the audience for their hardcovers, and to a lesser extent, a midlist from which promising new authors could be promoted to hardcover. Hardcover pricing was what kept the doors open and paychecks going out. Secondary markets were gravy.

Various forces are now turning the hardcover-centric business model on its ear. The single most important force here is not simply the ebook, but the fact that you can read ebooks on smartphones. Ebooks were dismissed early on because “nobody’s going to buy an expensive gadget just to read books on.” Well, dedicated ebook readers are no longer necessary. I have a Kindle Paperwhite because it’s easier on my eyes, but I’ve read plenty of books on my Galaxy Tab S3 and three different smartphones. Today, everybody has a smartphone, which means that everybody can read ebooks. It’s no longer a niche market.

This scares the crap out of traditional publishers. They have kept the cover prices of ebooks close to (or in some crazy cases higher than) hardcover prices, insisting that it costs just as much to create an ebook as it does to create a hardcover, dodging the truth that it’s all about physical inventory, returns, and unit cost. The unit cost of an ebook is zero. Inventory and returns no longer exist.

The second most important force is, of course, Amazon, home of The World’s Richest Man. Amazon did not create the notion of ebooks or ebook readers, but the Kindle Store allowed the emergence of independent publishing, more on which shortly. And the smartphone, in turn, created the market for the Kindle Store.

Amazon has systematically undermined the hardcover price point by allowing a nearly frictionless market for hardcovers that were read once and then sold through associate accounts for a third the cover price–or less–of the same book new. Amazon Prime created all-you-can-slurp shipping, and with improvements in logistics allows a book to be ordered in the morning and delivered in late afternoon. Why bother fighting traffic to get down to the last Barnes & Noble in town, when you can get the book just as fast (and more easily) with a few taps on your smartphone? (Yes, I’ll miss bookstores. But I won’t miss tchotchke stores.)

And last but by no means least, we have indie publishing. There are a number of platforms on which ebooks may be published, but realistically, it’s Amazon plus debris. They have wisely combined ebook and POD print book publishing into one entity. (90% or more of my sales are ebooks.) The system is straightforward enough to allow anybody with half a brain to publish their own books and short items on the Kindle store.

This means that a great deal of what is published isn’t worth looking at. We all worried a lot about that. But as it happened, people are discovering ebooks they same way they discovered print books in the old days: By word-of-mouth, which these days includes word-of-Web. Discovery sites like Goodreads help a great deal, as do Web forums with a topic focus. Amazon’s reviews are generally good, though you have to read a lot of them and average things out in your mind. Some people are hard to please, and others please way too easily. All that said, I’m very surprised at how few Kindle ebooks I have bought and then hated. Sure, some were better than others. But I did an odd kind of crosstime quality spot-check on marginal ebooks and SFF MMPBs from 50-55 years ago. Pull a passage from a 55-year-old no-name SF potboiler (easier now that the pages are coming loose as you turn them) and compare it to a no-name ebook SF potboiler you took a chance on for $2.99 based on Amazon reviews. The Amazon book wins almost every time. Why? Automated discovery, via reviews and recommendations. All we had to go on 50 years ago was the back cover, and a quick flip through the pages. Now we can be as fussy as we like, or at least as fussy as we have time for.

The bottom line on ebooks is that with automated discovery and online recommendations, you no longer need traditional publishing at all. I’ve bought some ebooks from the few traditional publishers (like Baen) who embrace them. But at least 75% of the SFF I’ve read in the last year has been from indie authors. Some books were better than others. Remarkably, all but a couple that I took chances on were worth reading.

I’ll miss BEA–a little. I had fun there and met some interesting people. I will not miss hardcover culture and its attendant weirdness. If the Big 5, er, 4 can’t shed that weirdness, the reading public will shed them, sooner than later.

In the meantime, it’s a marvelous time to be a reader–and an even better time to be a writer.

  • Wow. The magazine that gave us “The Case for Killing Granny” is now saying that our public health officials have overcounted COVID-19 deaths by counting any person dying with COVID-19 as dying of it–including suicides and, sheesh, car accident victims. This has been known for some time, but I give the otherwise dopey Newsweek credit for admitting that government isn’t always right.
  • More on how we count COVID-19 deaths: Johns Hopkins published a paper suggesting that we are overcounting COVID deaths and undercounting deaths from other causes like heart disease. By misclassifying deaths as from COVID, we undercount deaths from other causes. The authors of the paper suggest that this means COVID-19’s impact on US deaths is far less than commonly stated. Johns Hopkins has predictably deleted the article, but there’s an archived copy on The Wayback Machine. Well worth a read–and possibly worth saving the original Johns Hopkins article to local disk in case threats of legal action force Wayback to take their copy down.
  • A new paper posits that UVB in sunlight stimulates the production of antimicrobial peptides (AMPs) in the skin, especially cathelicidin (LL-37). LL-37 has several roles, but it has been shown to inhibit the action of the influenza virus in humans. AMP action involves Vitamin D, but the D3 found in OTC supplements does not appear to work with it. My serum D3 tested toward the top of the recommended level several months ago, but it’s hard to know how much of that was produced in my skin in this (outrageously) sunny place, and how much came to me in pills.
  • David Prowse, who played Darth Vader in the original Star Wars movies, died yesterday, at 85. He was 6’6″ and was given the choice of playing either Vader or Chewbacca. He chose Vader because “you always remember the bad guy.” (Well, true. But nobody’s going to forget Chewie, either.) Click through to it: The photo of gentle giant Prowse with six little girls in a UK safety program is priceless.
  • Somebody did a test on the startup time required for programs written in various languages, including nearly all of the ones I’m familiar with. (At least those that weren’t Xerox in-house experiments.) FreePascal 3.0.2 and 3.0.4 beat all the others, hands down, not even close. I don’t know enough about compiler internals to tell how one gets that kind of startup performance, but you sure as hell do not get it with C# or Java.
  • I should add that if you’re on Twitter and work in Pascal, you must follow @SciPasTips.
  • Bummer: The Arecibo radio telescope will be scrapped. Stuff is breaking in the basic structure of the mechanism that just can’t be swapped in without rebuilding practically the whole thing. That reflector comprises eighteen acres. It’s been in operation for 57 years. Wait! I have an idea! Let’s build an even bigger one…in space! (Yes, I’m pretty sure Heinlein thought of it first.)
  • As far as I’m concerned, this kid wins the Best Halloween Costume Award not only for 2020, but for the rest of time.

Bringing the 10″ Scope Back to Life

Nov 29th, 2020
by Jeff Duntemann.

Joe Lill and 10 Inch Newt - 3-8-1970 - Cropped.jpg

When I was 14, I took an opportunity and started out on a very large project: A friend of mine bought an Edmund Scientific mirror-making kit, decided he didn’t have the time to pursue it, and sold it to me. The kit included a 10″ Pyrex mirror blank, a plate glass tool blank, and all the abrasives needed to grind and polish it. I did most of the grinding in my basement, using a defunct round wringer washer as a grinding station. I followed the instructions in the kit, along with whatever I could find in the library, and though it took a couple of months, in time I had a Pyrex blank with a smooth curve, focusing at about 67 inches. My goal was 70, so I came pretty close, and in truth, 67″ would make for a shorter and somewhat lighter tube.

Now, grinding is only half the job. Polishing the ground mirror surface took sophisticated methods to gauge the accuracy of the curve, which has to be a parabola to focus items at infinity (like stars) to a sharp image. I decided I was over my head, and did the sensible thing: I enrolled in a class at the Adler Planetarium on Chicago’s lakefront, which took up most of the summer that I turned 15. They had an optical shop in the basement that included the required Focault tester, plus a superb teacher, Ken Wolf, who helped me get the polishing done and mirror curve accurate. They were also able to aluminize it, and by that fall, I had a 10″ F6.7 parabolic telescope mirror accurate to 1/25 wave, which was bogglingly accurate for a first shot by a 15-year-old.

The rest of the scope took another two years and change to complete. A friend’s father made me a tube out of sheet aluminum. I built a tube saddle out of scrap wood and hardware-store aluminum stock. I had no tools more sophisticated than my dad’s circular saw and saber saw. And that was for woodworking–for metal I did it all with a hacksaw and files. I had some help from my high school machine shop teacher, who dug up a piece of iron that he said was hull metal from a scrapped battleship. He cut it to size on the big bandsaw for me. I spent many study hall hours in his shop on one of the lathes, boring out 2″ pipe fittings and making numerous small parts. I owe Mr. Brinkmann a huge debt of gratitude. Without his help and the use of his machines, I could not have finished the scope.

It was going to be a big scope, and a much heavier one than the 8″ Newtonian I had built from a Sam Brown book the summer I turned 14. I turned my attention to building a base. There was a lot of scrap lumber in the crawlspace. I had the notion of building a cement form out of scrap lumber and pouring a solid triangular concrete shape 36″ on a side with bolts embedded in the top for the battleship-metal mount.

So I built me a cement form.

Whoops. Doing some math and library research showed me that the concrete base would weigh at least 400 pounds. Yes, I could make it–but once I made it, I had no idea how I would move it. So I was left with a scrap lumber cement form…

I.D.E.A!

FirstDateSketchTelescope - 325 Wide.jpgThe form was made entirely from 2″ dimensional lumber, from 2X4s to a scrap of 2X12. I could carry it around with only a little puffing. So I would use the cement form as the telescope base.

A lot more work and allowance money would go into the telescope before I finished it–more or less–in the fall of 1969. On an early date with a pretty 16-year-old girl I had met in church, I told her about the project and drew a picture of it on her little spiral notebook. (See left. She enjoyed talking about science. So did I. She married me in October 1976, and our flag still flies.)

I used that scope a lot, even though it was bulky and heavy and awkward to cart around. In 2000, I (finally!) poured a concrete base for it at our house at the north end of Scottsdale. (See below.) I bought a large plastic trash can to put over the scope to keep the weather off it, and enjoyed it tremendously. Well, we moved to Colorado in 2003. When I went behind the garage to fetch out the now-retired wood base, I discovered that the local termites had been feasting for a couple of years, and there was nothing much left.

I haven’t had the 10″ assembled since. And it’s now about damned time to get to work.

10 inch with Michael Abrash - 2001 - 500 Wide.jpg

I’ve spent a couple of weekends messing with it. Yesterday I bolted the aluminum tang to the base, and although there will be some refinements, what you see below is pretty much what you’ll see when it’s in service.

New 10 inch wood base 1- 500 Wide.jpg

The equatorial head is still workable, though tremendously heavy. I hope to build a new one out of aluminum. In the meantime, I see no reason why I can’t have it up and working by the time of the Great Conjunction of Jupiter and Saturn on December 21. The two giant planets will appear just 6.1 arc-minutes apart, close enough to see in the same eyepiece field, and closer in the sky than they’ve been since 1623. A conjunction of this sort is said by some to be the Christmas Star that the Three Wise men followed to Bethlehem. Miss that? No way!

More on the 10″ scope project as it happens.

I’m Still Here

Nov 28th, 2020

I’m still here–and still healthy. One of my correspondents asked in an email if I had stopped writing on Contra because I’d caught the virus. I haven’t. Motivation and energy are an issue, with both in somewhat short supply. That said, the truth is that Contra is mostly for long-form essays, and I’ve been stumped for concepts recently. I don’t want to talk about the election. There’s nothing I could say that others haven’t said a zillion times. And the pandemic is depressing enough. Politics would put me into a coma.

There are other issues that I’m sure I could talk about, and I’m pondering one now, which I hope to post in the next few days. And I need to do an Odd Lots. What I need to do most of all, however, is stop waiting for a 3,000-word entry to occur to me. Personal energy might allow me to get the ideas, but it might not allow me to produce the copy.

So what I may do here is go back to short subjects for awhile. I may duplicate entries posted here on MeWe or possibly Facebook. I’m annoyed at Facebook for blocking a link to a news item because Facebook doesn’t like the site. They didn’t say the item itself was false or misleading. They just said that the site wasn’t trustworthy. Well–who’s trusting the New York Times these days? Mostly people who agree with them. Is that the future? All media becoming hyperpartisan and excluding links to sites for strictly ideological reasons? That’s pretty depressing too.

And that’s why I created an account on MeWe. Unlike Facebook, they don’t have enough subscribers to allow them to alienate 49% of their readers with stupid ideological posturing. The list of things they won’t allow is short and sensible: Nudity/porn, threats of violence, impersonating other people, etc. It does not pass judgment on legal content. It doesn’t sell ads or track users. It’s American-owned. Its business model depends, like so many others, on selling premium accounts. Whether that’s enough to keep them afloat over the long haul is debatable. But for now, with millions of disgruntled Facebook users flooding in, its future looks tolerably bright.

This entry is just to reassure you that I haven’t abandoned Contra. I’m going to spend a good part of the afternoon writing and queueing up some shorter entries that I will post in coming days. That’s what I did when I created Contra (and its predecessor, VDM Diary) 22 years ago. So everything old is new again…except maybe bell-bottoms and BASICA.

The Odd Lots Project

Every so often someone sends me an email to ask, “Is there any place I could find your story ‘Our Lady of the Endless Sky’? I read it years ago and it was a really good story. I’d like to read it again.” Swap in the title of any of several other stories or idea pieces that I published in PC Techniques / Visual Developer what seems now like decades ago–because it is. Some of my idea pieces and humor from the magazine are already up, linked in an archive page that you can find here.

Still, it’s only a few of them, mostly because for those few I still had the original word processor files. Most of those files have been lost. All that remains are the magazines themselves.

Five or six years ago I sketched out an idea for a book containing some of the old BEGIN / END / The Vision Thing / Breakpoint pieces, plus some of my better Contra entries. For almost four years I was occupied with my new novel Dreamhealer. (The paperback edition is now for sale on Amazon, so that project is finally complete.) With Dreamhealer out of the way, a week or so ago I started building a TOC and searching out files for as many pieces as I still have. Some had to be scanned and OCRed from the magazines. Some were buried in odd folders in my data drive. All of them needed cleaning up. Quite a few I have only in WordPerfect format. Fortunately I can convert these using a handy utility called QuickView Plus. The Contra entries are copy’n’paste.

I work on it when time permits. I now have 45,000 words in the master Word file. My target is 75,000 words. There’s still plenty of scanning and OCRing to do, plus introductions to put all this ancient stuff in context.

The book will have seven sections:

  1. Essays and Editorials
  2. From Contrapositive Diary
  3. Poetry (maybe)
  4. Parody
  5. Memoir
  6. None of the Above.

The Poetry section may not happen. I’ve only written three poems in my life that I would show to the general public. Two of them are e.e.cummings pastiche and one Robert Frost pastiche. When God was handing out poetry genes I was standing in the Whimsical Tutorials line. (Fortunately, it was a short line.)

One thing that won’t be included in Odd Lots is “STORMY vs. the Tornadoes,” which appears in my AI SF collection Souls in Silicon . There are a few items that fall in the forbidden zone between fiction and nonfiction, which is what the “None of the Above” section will capture.

I will publish it in both Kindle ebook format and trade paperback. I don’t have a timetable yet, but in nice round numbers I’d like to see it laid out and ready to publish by the end of the year. When I flesh out the TOC a little more, I’ll post it here, and if you remember something that you liked but don’t see in the TOC, let me know in the comments.

The biggest task for now is simply reviewing Contra to remind myself what I’ve done. This is a challenge, as I’ve been publishing Contra now for 22 years and have about 5,000 entries. I’m working on that. So stay tuned. This will be fun. I don’t expect to sell thousands of copies. Mostly what I want to do is put a lot of my mostly-forgotten work back in the public eye. This’ll do it.
