Temporarily Locked on Top.
About six months ago, it suddenly became the case that you had to do something every 90 days to update your SSL Certificate, or else anyone logging onto your web page got redirected to a warning that yours is an insecure site.
It took several occurrences before it dawned on my dim reptilian intelligence that this unhappy state of affairs was going to keep happening and steps needed to be taken to avoid it. When I looked into it, my hosting company explained that I could switch to a different hosting plan on a different server for a few bucks more per month.
Sure, I said, Let’s do that.
Well, they took their time, and moved NYM on Thanksgiving Day. Chaos ensued. Connecting to NYM commonly produced 103 — Bandwidth Exceeded errors, and trying to upload a post crashed WordPress.
It turned out that they offered me a plan with hardly any bandwidth, completely inadequate for NYM’s traffic. And changing servers resulted in several plugins acting up and causing everything to crash.
I used to get great support from Hostica, but this time I was left hanging with no responses. So I pulled the plug on Hostica.
I moved over to a new hosting company, which it turns out, amusingly, is in Lithuania. (I’m of Lithuanian descent, you see.)
Things are not entirely different. I’ve been discovering that, nowadays, these hosting companies all seem to expect to you go to their site and fiddle with the mechanics of it all yourself. Since the need arises once every five years or so, one’s personal familiarity with all this is lacking.
So… the migration has been done, and NYM’s new Name Server Address has finally propagated (It can take 48 hours). It is not crashing so far. And I set up SSL so you should not get warnings. The only problem is that I seem to have lost a couple of days recent postings.
More surprises may be in store, but I think the worst is over.
Sigh, I used to be hosted by this religious fanatic nerd in Texas. I could just phone Ed, and Ed would fix whatever. Unfortunately, somebody hired Ed for a real IT job and part of the deal included Ed giving up moonlighting as a hosting service.
UPDATE: I just found that I’ve got the blog from yesterday sitting on an open browser page, so now I can just, laboriously, reload all the missing postings.

Cell Mate Chastity Cage (Short Model).
A $189 Chinese Bluetooth Chastity Ring designed for Domination games, or mere assured fidelity, has been shown to be vulnerable to hacking, and can be permanently locked by third parties, requiring the use of an angle grinder or other heavy power tool to cut the device off. A drastic solution, to say the least.
Additionally, its security flaws allow the hacker to steal the user’s passwords, birthday, location, and other sensitive data.

The moth and fly embroideries are as elaborate and astonishing as the naturalistic trout fly imitations devised by the late Bill Blades. Cf. William Blades, Fishing Flies and Fly-Tying, 1951.

Interior of the Pantheon in Rome.
In his excellent King Arthur’s Wars: The Anglo-Saxon Conquest of England (2016), retired British officer Jim Storr (now teaching at the Norwegian Military Academy in Oslo) puts the astonishing Roman technological achievements into perspective.
Roman engineers… were astonishingly skillful. In the years just before the birth of Christ they built an underground tunnel to bring water to Bologna in Italy. The tunnel was 20 kilometres long. Hundreds of years earlier they had drained the Pontine marshes south east of Rome. In the second century A.D. they brought water to a city in what is now Syria from a source over 130 kilometres away. It had an average gradient of just 3 centimetres’ fall in every kilometre. Many kilometers of it still exist today. In several cities in Europe, Roman aqueducts still provide water from several kilometres away. The world-famous Trevi fountain in Rome is supplied by the Virgo aqueduct, 22 kilometres long and built in 19 BC. The Pantheon in Rome was built in about 126 A.D. It is the world’s first large mass-concrete dome building. It is over 40 metres high and is visited by thousands of tourists, in complete safety, every day: almost 2000 years later.
Roman engineers were not just good builders. They were also world-class surveyors. If you walk south from London Bridge today, you soon reach Kennington Park Road (the A3). As you look along it you are looking in the precise direction of the east gate of Chichester, 59.84 Roman miles from the end of London Bridge. The surveyors who first laid out that road, probably in the first century A.D., knew precisely which direction Chichester lay in. There are two major rows of hills (the North and South Downs) in between.
In about 155 A.D. Roman surveyors re-aligned a section of 82 kilometres of frontier defenses in southern Germany. The southernmost 29 kilometres ran over several heavily wooded ridges, yet none of the forts (a Roman mile apart, with turrets in between) is off the direct line between start and finish by more than 1.9 metres. That is a deviation of less than five minutes of arc (five sixtieth of a degree). The accuracy which Roman surveyors achieved was phenomenal. It was only bettered with the invention of surveying instruments with magnifying optics (such as the theodolite) in the 17th century. Yet, as far as is known, Roman surveyors did not even have an instrument for observing and copying angles directly (such as a protractor). However, by about the year 500 or so, nobody could even build in stone, let alone lay out aqueducts or build in concrete. Concrete only came back into use in the late 18th century.

New Apple Mac Pro and the 6K Pro Display XDR display.
Stephen Green approves of Apple’s new stratospherically-priced Pro computing equipment (even if he can’t afford that $999 stand).
At Apple’s annual World Wide Developer Conference (WWDC) earlier this week, the company announced its forthcoming modular Mac Pro, and its impressive accessory, the Pro Display XDR reference-class monitor. I watched the big keynote on Monday, and if the crowd winced when the Mac Pro’s starting price of $5,999 was revealed, you couldn’t tell. The auditorium full of developers maybe shifted in their seats a bit when they were told that the Pro Display would cost $4,999, but in the end they understood that a monitor with its specs is a game-changer for pros, because it goes toe-to-toe with the $40,000 (that’s right: forty-thousand dollars) displays Hollywood studios rely on.
But there were unhappy gasps when they heard that the XDR’s optional stand — and it is admittedly an impressive bit of engineering — would retail for $999. Sitting here at home, even I gasped a bit. The whole thing was just so much that it got Engadget’s Devindra Hardawar to opine that a “$999 monitor stand is everything wrong with Apple today.”
Au contraire, a $999 monitor stand is everything right with Apple today. And no, I’m not being facetious, or day-drinking any more than I usually might.
With its industrial-ugly purity of form, its over-engineered ergonomic perfection, (jeez, I’m sounding like a Jony Ive promotional clip) and its indefensible price tag, this stand represents Apple’s re-commitment to the actual professional user community which the company has all-but-ignored in recent years. And it doesn’t just sit there and hold your monitor for you. The pro stand attaches to the XDR monitor without screws, but with the simple click of some magnets. From there, the stand makes the giant screen infinitely adjustable (and rotatable) with the gentle push of one finger, yet won’t budge when you don’t want it too. It’s a real piece of work.
Here’s the thing. The new Mac Pro and XDR monitor aren’t for you. They aren’t for me. They likely aren’t for anyone you know, and maybe not for anyone the people you know, know. They’re for video/audio/design professionals for whom a $50,000 (or more) workstation setup is a just a typical cost of operations. …
The prosumer in me is, in a way, just as disappointed as those folks at the WWDC who’d been hoping to buy tomorrow’s Mac Pro at yesterday’s prices. What we’ll settle for is getting prosumer performance at what used to be consumer prices.
As for that optional $999 stand, those who actually need it won’t ask the price — and can afford not to. Besides, it’s nice to see Apple finally put the Pro back in Mac Pro, even if there will never be another one on my desktop.

What could possibly be better for state surveillance and control? (Logic Magazine)
This summer I spent a month in Beijing. Iâ€™d last lived in China in 2016, and I was relieved to find my favorite noodle shops in their usual niches. But this time round, navigating the city felt inexplicably different. The cabs I tried to hail passed me by. On the subway, other riders jostled past me, swiping their phones at the turnstiles as I fumbled with my ticket. When I tried to sneak into the cafeteria in Renmin University for a cheap lunch, clutching my grubby backpack, I made it past the guards only to be stopped at the cash registerâ€”apart from student cards, the only form of payment accepted was Alipay.
It gradually dawned on me that that was why Beijing felt like a different city from the one I knew: in the two years since Iâ€™d left, the whole city had switched over to mobile payments on China-specific platforms to which I, a foreigner, had no access. These days in Beijing, the green and blue logos of mobile payment providers WeChat Pay and Alipay appear everywhere, from breakfast stalls to five-star hotels.
Just about every foreigner whoâ€™s visited China in the last ten years comments on the dizzying speed at which physical infrastructure is built. When I first moved to Shanghai in 2012, I worked in the cityâ€™s financial district, home to a skyscraper nicknamed the â€œbottle openerâ€: according to Wikipedia, itâ€™s the worldâ€™s tallest building with a hole in it. But these days, Chinaâ€™s part in the race to build the worldâ€™s tallest building appears to be waning. Chinaâ€™s much-vaunted speed in infrastructure building has more recently been directed at the digital rather than the physical world.

Nicholas Phillips, at Quillette, delivers up a hearty serving of old-fashioned curmudgeonly skepticism of the benignity of all technological change. No Robotic Communism for him!
When forecasting the future, perhaps the only thing that can be trusted is the emergence of unprecedented, unpredictable events that violate past trends. On the eve of the 2008 subprime mortgage crisis, none of the models used to forecast house prices accounted for the possibility of a price collapseâ€”for the simple reason that no such collapse had ever happened. Price data was historical, and extrapolating that history into the future rendered us blind to the possibility that something ahistorical might happen. Or as Pessimists Archive unwittingly put it: the possibility that â€œthis time itâ€™s different.â€
But techno-optimists take the exercise a step further, by using data about one thing to forecast the future of an entirely different thing. This moves us from the flawed to the absurd. For instance, when techno-optimists compare anxiety over driverless cars to the protests of the horse-and-buggy industry over the automobile, they ignore the ways that driverless cars implicate fundamentally different problems than did automobiles. Driverless cars stand ready to collect immense amounts of personal data about the habits of their passengers, and their networked structure creates serious national security risks. What could the successful debut of the automobile in the early 20th century possibly tell us about that?
The political philosopher Gerald Gaus argues that the less precedent there is for some practice working, the less reason there is to prefer it. In the case of new technologies that implicate brand-new problems, the data we have about the success of past technologies is simply irrelevant. History gives us no reason to prefer a world in which, for example, most manual work is automated. Itâ€™s never happened before.
We draw spurious historical analogies precisely because itâ€™s easy. If we can say that Change A is just like Change B, which went fine, it allows us to avoid grappling with the actual qualities of Change A. Argument by analogy displaces argument on the merits. Itâ€™s far more convenient to assert that past change was good, present change is just like past change, therefore present change is good too.
Unfortunately, by any objective measure, most new things are bad. People are positively brimming with awful ideas. Ninety percent of startups and 70 percent of small businesses fail. Just 56 percent of patent applications are granted, and over 90 percent of those patents never make any money. Each year, 30,000 new consumer products are brought to market, and 95 percent of them fail. Those innovations that do succeed tend to be the result of an iterative process of trial-and-error involving scores of bad ideas that lead to a single good one, which finally triumphs. Even evolution itself follows this pattern: the vast majority of genetic mutations confer no advantage or are actively harmful. Skepticism towards new ideas turns out to be remarkably well-warranted.
The need for skepticism towards change is just as great when the innovation is social or political. For generations, many progressives embraced Marxism and thought its triumph inevitable. Future generations would view us as foolish for resisting itâ€”just like Thoreau and the telegraph. But it turned out that Marxism was a terrible idea, and resisting it an excellent one. It had that in common with virtually every other utopian ideal in the history of social thought. Humans struggle to identify where precisely the arc of history is pointing.
Techno-optimists would likely prefer to put aside failed products and ideologies and consider instead those innovations that have already proven successful. Weâ€™re talking about the iPhone, after all. Is popular adoption of an innovation reason enough to suspend skepticism? Noâ€”we turn out to be quite bad at predicting the full impact of even our most successful ideas. Adding lead to gasoline made automobile transportation more efficient, but it caused widespread brain damage and may have been responsible for the 20th century crime boom. Freon in refrigerators punched a hole in the ozone and had to be banned by international compact. Fossil fuels, one of the most successful product innovations in history, are experiencing what might politely be called a re-evaluation.
Another massively successful innovation undergoing a re-evaluation of its own is the internet itself. Optimists promised emancipation: knowledge would be democratized and civil discourse would flourish. Now, we understand that the internet is also a highly effective system of control. Incentives to commodify personal information have resulted in more and more of our daily lives becoming subject to data collection, transforming our economy into a surveillance ecosystem. This renders our conduct â€œvisibleâ€ to states, which can punish us for itâ€”as China is doing now through its dystopian â€œsocial creditâ€ system. The whole thing could turn out to be a terrible mistakeâ€”we donâ€™t know, because weâ€™ve never had to solve this problem before. The fact that we previously solved the problem of the telegraph is irrelevant. One could probably fill a podcastâ€”call it the â€œOptimistsâ€™ Archiveâ€â€”with inappropriately rosy predictions about the wonders of new technology.
We are engaged in a giant social experiment. For 99 percent of the time humans have lived in settled societies, life in each generation was essentially like life in the generation before. Stasis, not change, was the rule. Now, for the first time, we live differently, and the gap between the generations grows wider as the pace of change grows faster. Can this continue indefinitely? We have no precedent for that working. Analogies to history are analogies to nothing at all. We might as well analogize the driverless car to the hand-ax.
Instead of empty analogies, the only way to survive change is to have a vigorous debate about the merits of our new ideasâ€”precisely the kind of debate that techno-optimists want to foreclose by appealing to history. We might ask instead: what does this new thing do to us? Do we understand enough to answer that question? If not, on what basis does our confidence rest? Debate on the merits is essential to distinguishing good ideas from bad ones. And for that, you need the people that techno-optimists most loathe: conservatives.

Slate has the story.
When Kurt Luther walked into Pittsburghâ€™s Heinz History Center in 2013 to attend an exhibition about Pennsylvania during the Civil War, he didnâ€™t expect to be greeted by his great-great-great-uncle. A computer scientist and Civil War enthusiast, Luther had been drawn to researching his own familyâ€™s connection to the conflict, gradually piecing together information over years and years. But his searches had always failed to turn up a photograph, and Luther was ready to give up on the possibility of ever seeing his ancestorsâ€™ faces. It was only through sheer happenstance that, walking through the History Center that day, Luther had spotted an album of portraits of the men of Company E, 134th Pennsylvaniaâ€“â€“his great-great-great-uncleâ€™s unit. Laying eyes on his relativeâ€™s face for the first time, he later wrote, felt like â€œclosing a gap of 150 years.â€
Five years later, Luther launched Civil War Photo Sleuth, a web platform dedicated to closing the gap a little further. Together with Ron Coddington (editor of the magazine Military Images), Paul Quigley (director of the Virginia Center for Civil War Studies), and a group of student researchers at Virginia Tech, Luther crafted a free and easy-to-use website that applies facial recognition to the multitude of anonymous portraits that survive from the conflict, in the hopes of identifying the sitter. When a user uploads a photograph, the software maps up to 27 distinct â€œfacial landmarks.â€ Users are further able to refine their searches by adding filters for uniform details that could offer clues about rank. (Three chevrons and a star, for instance, indicates a rank of ordnance sergeant for both the Union and Confederate armies, while shoulder straps with an eagle were worn by Union colonels.) From there, the program cross-references the photo with the other images in CWPSâ€™s growing database. The final search results present an array of possible matches (and possible names) for consideration.
It’s all the facial fungus that makes it hard.
