VerDeTerre··on Medieval medicine under the spotlight in major new project
This was an example of the dubious kind of parapsychology experiment conducted during the period. I'm sure there were true believers, but I think healthy skepticism probably prevented people from pursuing it too seriously, even when positive results were reported.

> People back at shore would dip the bandages from a wound inflicted on a dog, which would supposedly cause the dog on board to yelp.

That kind of morbid experimentation was apparently still in fashion during the Cold War:

> Dr. Pavel Naumov … conducted animal biocommunication studies between a submerged Soviet Navy submarine and a shore research station; these tests involved a mother rabbit and her newborn litter and occurred around 1956 … . When the submarine was submerged, assistants killed the rabbits one by one. At each precise moment of death, the mother rabbit's brain produced detectable and recordable reactions.

VerDeTerre··on VanMoof’s team of ‘bike hunters’ appears to succeed where the city doesn’t
This is the way to go if you have the option. If you need to keep the bike outside but have a reliable designated area, you may want to consider leaving a heavy chain and padlock on site. If you don't have to carry it with you, you can invest in extra robustness.

If you're talking about trips in addition to the commute to the office, the considerations really depend on the location. The sturdier the lock the better, but in many cases, a superior lock out of view could be considered worse security than a lesser lock with more eyes on.

You'd be well-advised to secure, in addition to the frame, components like wheels and seat, especially if they're quick release. For that, a lighter cable (maybe even one with a built-in combo lock) might suffice as deterrent, but again, it depends. Some of our opportunistic friends seem to be more interested in wheels than frames.

VerDeTerre··on Arecibo telescope, on the brink of collapse, will be dismantled
I would not have guessed the scale. The article says the instrument platform weighs 900 tons, which is amazing to imagine. At first, I wondered if they could use a helicopter to bring it down safely, but it's like two or three 747s on a tight rope.
VerDeTerre··on Researchers fear that vaccines might not be as effective in people who are obese
Your first-hand experience isn't universally applicable. Many people live in food deserts or don't have access to reliable cooking facilities. And physical exercise costs time, which for many is lost to long commutes.

As you indicate, though, healthy food isn't intrinsically expensive. That means it shouldn't be an intractable problem.

VerDeTerre··on Why Are Plants Green? To Reduce the Noise in Photosynthesis
I had heard of the similar Purple Earth Hypothesis[1] wherein organisms with photosynthesis based on retinal arose in the oceans early on. Chlorophyll-based life developed deeper and took advantage of the red and blue light that filtered through.

The hypothesis seems pretty speculative, but maybe it's compatible with this new research, which could explain why green plants came to dominate despite retinal being simpler.

VerDeTerre··on Whole Earth Software Catalog (1984)
I've donated in the past, but with the recent copyright debacle, I'm less inclined to—not so much because I think they're clearly on the wrong side of the law (though I do believe so), but more because it seems like such an obvious and potentially catastrophic misjudgment. I'm fine with information activism, even if I'm not totally on board with the full program, but not at the expense of endangering the core mission. I don't think their actions will yield a valuable test case, so I'd prefer to see them instead work towards copyright reform in a more measured manner. I'll probably continue to support them because it's such an amazing resource and so many people are doing great work, but the leadership does not, at this time, have my confidence.
VerDeTerre··on Don't rinse with water straight after toothbrushing
Fluoridation is by no means universal in the US—around 69.2% of public water in 2006, according to Wikipedia[1]. In some areas, resistance is strong and cuts across diverse political orientations. Portland's 2012 attempt to fluoridate, for example, drew opposition on the basis of libertarianism, environmentalism and science skepticism.

VerDeTerre··on Amazon Prime video gives amateur how-to’s, conspiracy theories a stage
Or, to belabor the disease analogy, an opportunistic infection. Distrust makes it easier for otherwise fringe sources to spread beyond what would be expected in a healthy media environment.
VerDeTerre··on No Spice More Superior: Pepper
While I suspect that's largely true, I was intrigued by the article about "The Great Sushi Craze of 1905" that appeared a few years ago (http://eccentricculinary.com/the-great-sushi-craze-of-1905-p..., https://news.ycombinator.com/item?id=10003510). It offers a minor counterpoint and also suggests access to and curiosity about foreign cuisines can wax and wane.
VerDeTerre··on Clothing Britain’s Spies During World War II
As I understand it, when the Germans occupied Paris, they saw it as a key prize and were keen to keep its culture alive, at least superficially. There was a fair amount of prestige in sending home something refined. Imagine--if the city lost its luster, the perfume and garments the soldiers sent home to their sweethearts wouldn't seem quite so special! The fashion industry continued to operate, with styles changing seasonally, another thing besides regional differences for the SOE to contend with. Only a spy would sport last month's hairstyle!

It also meant an opportunity for Section F members operating in France. At home in Britain, clothing was rationed, but as recounted in "Carve Her Name With Pride" (about Violette Szabo), "Out shopping by herself the next day, she went to Molyneux, the famous couturier in the Rue Royale, which, despite the German occupation, was still carrying on.... Here she bought, as her bill dated April 28th, 1944, shows, three dresses and one very attractive jersey. The bill, made out to Mademoiselle C. Leroy, states that one of the dresses was of black crêpe de chine--it was draped with a lace neckline and cost 8500 francs.... Another of the dresses is set down as 'en écossais': it was a red plaid dress. The third was of silk print. The jersey, described as a golf jersey, was yellow in colour. The total bill, with a purchase tax of 11 per cent, a municipal tax, and a 'Taxe au profit du secours national' of 5 per cent, came in all to over £200."

It's strange to think that between blowing up bridges (probably not literally in the case of spies in the city), the agents could go on a shopping spree in Paris's posher establishments.

VerDeTerre··on Smallest crew required for a multigenerational trip to Proxima Centauri
This analysis assumes conventional reproduction, which is probably just as interesting in the context of general population studies; when it comes to dealing with the issues in space travel, however, there would be a number of options for dealing with genetic diversity (possibly even without relying on any significant advances in biotech). For example, you could send along a large sample of genetic material (gametes or fertilized eggs, for instance) taken from a broader swath of the population. In that case, I'd be curious about the sociological and psychological consequences of a group in which children might never be genetically related to their parents.

A more science-fictiony approach might be to simulate genetic combinations and synthesize resulting embryos. You could start with the actual parents, pairing their genes with a database of outside contributions for an arbitrary number of generations. In effect, you could give birth to a distant descendent.

I think the fertility issues could present bigger challenge, possibly requiring a technological assist. And when the simulated catastrophe hits, I suppose it's time to spin up the spare incubators and get ready for some sleepless "nights".

On a side note, I thought it was amusing their inbreeding calculations included identical twins. Maybe that was just to establish a theoretical limit.

VerDeTerre··on The Meta-Problem of Consciousness [pdf]
I’ve had the same thought, inspired by similar incredulity. I wonder if there’s a feeling that anything short of strict physicalism is just a flavor of dualism. Better a philosophical zombie than a philosophical ghost?
VerDeTerre··on Ebay shuts down Half.com
I don't think it's entirely a matter of Half.com becoming obsolete because of changes to eBay; I suspect they lost out to Amazon Marketplace, which provides basically the same service with (I'd assume) a larger reach. I would often check both sites and see the same listings by the same sellers.
VerDeTerre··on Judge orders tech company to release Web user data from anti-Trump website
In effect, it did happen. A number of American citizens were prosecuted and convicted under the Federalist-supported Sedition Act of 1798, which included the following:

"And be it farther enacted, That if any person shall write, print, utter or publish, or shall cause or procure to be written, printed, uttered or published, or shall knowingly and willingly assist or aid in writing, printing, uttering or publishing any false, scandalous and malicious writing or writings against the government of the United States, or either house of the Congress of the United States, or the President of the United States, with intent to defame the said government, or either house of the said Congress, or the said President, or to bring them, or either of them, into contempt or disrepute; or to excite against them, or either or any of them, the hatred of the good people of the United States, or to stir up sedition within the United States, or to excite any unlawful combinations therein, for opposing or resisting any law of the United States, or any act of the President of the United States, done in pursuance of any such law, or of the powers in him vested by the constitution of the United States, or to resist, oppose, or defeat any such law or act, or to aid, encourage or abet any hostile designs of any foreign nation against United States, their people or government, then such person, being thereof convicted before any court of the United States having jurisdiction thereof, shall be punished by a fine not exceeding two thousand dollars, and by imprisonment not exceeding two years."

VerDeTerre··on Jane Austen, on the money
With irony in vogue but subtlety out of fashion, absurdity treads a fine line. A line no wider, even, than the itsy-bitsy Mississippi.
VerDeTerre··on Jane Austen, on the money
Of the former quotation, I at first thought, "How terrifically jejune." Then, naturally, I wondered how reading P&P became a recurring annoyance for him. Was it simply for self-indulgent infuriation? In the end, I am left simply to lament: all those readings, and he never learned to appreciate satire.

Sounds like Alfred Bester's "Adam and No Eve" from 1941. It's included in https://www.amazon.com/Virtual-Unrealities-Fiction-Alfred-Be...
