Increasing hazards to navigation in the East China Sea
It’s odd that all the increased collisions seem to involve Chinese vessels:
Sci-fi genius Robert Heinlein warned readers never to attribute to villainy behavior that was adequately explained by stupidity. In other words, he believed malice should be the explanation of last resort for puzzling conduct on the part of people or groups of people; it shouldn’t be the default. Better to hunt for more benign explanations first. With apologies to Heinlein, I would amend his “razor,” or heuristic, slightly. It’s too narrow. There are other candidates than stupidity or purposeful villainy to account for misconduct. Factors like incompetence, bureaucratic inertia, and sheer accident form — and sometimes deform — human thought and action. They belong on the stupidity side of Heinlein’s ledger.
How about this: Never attribute to villainy behavior that can be adequately explained by human failings. That preserves the essence of Heinlein’s razor while widening its scope to fit reality.
Let’s use his revised heuristic to evaluate the Sino-Japanese collision. It’s certainly possible the mishap came about by accident. It took place at night, in crowded waters. If the U.S. Navy collisions of 2017 taught us nothing else, it’s that the crews of even frontline warships can suffer from a host of maladies, from overwork to shoddy personnel practices to doctrinal or training shortfalls. No amount of high technology — whether it’s Aegis radar or satellite navigation — can altogether forestall human error. It may be that the Japanese crew, the Chinese crew, or both blundered around in the dark and came to grief. By Heinlein’s lights that’s the generous and proper assumption until the facts become known. If they do.
Nevertheless, a silent corollary has to be appended to Heinlein’s razor: But don’t rule out villainy, either.
Especially when it comes to the Chinese Communist Party (CCP). For decades Beijing has made militiamen embedded in the Chinese fishing fleet an arm of maritime strategy. The maritime militia is an irregular adjunct to regular naval forces, including the People’s Liberation Army Navy (PLA Navy) and especially the musclebound China Coast Guard fielded over the past decade. Beijing touted the militia’s combat prowess as long ago as 1974, when Chinese naval forces wrested a tottering South Vietnam’s holdings in the Paracel Islands from it in a brief but bloody sea battle. Militia craft backed by the coast guard have been a fixture in the South China Sea ever since 2009, when Beijing declared “indisputable sovereignty” over the vast majority of that body of water — including seas allocated to its neighbors by treaty. The irregular force went into overdrive in 2012 during the standoff with the Philippine Navy and Coast Guard at Scarborough Shoal, deep within the Philippines’ exclusive economic zone. Fishing craft flood the zone in CCP-claimed waters and dare local coast guards or navies to repulse them. If the locals resist, the China Coast Guard backs up the militia. PLA regular forces provide a backstop should things go awry.

Published 9 Apr 2020Understanding joinery can be confusing, especially is this so when industry confuses the issues by introducing terms like dowel joint, biscuit joint and domino joint.
I hope that we can all see to it that the art of true joinery remains as both the industry and the non-industry standard that preserves the skilled work of artisans working these three joints into their projects. I also hope that this video helps everyone to understand why there is a difference.

James J. Hill, US railroading’s premier “market entrepreneur”
Dane Stuhlsatz outlines the story of US federal government subsidies and other interventions into the 19th century railroad industry and the one tycoon who avoided the lure:
Burton W. Folsom, Jr. outlined this story in his book, The Myth of the Robber Barons, identifying two models of entrepreneurship; the “political entrepreneurism” of lines like the Union Pacific and Central Pacific versus the “market entrepreneurism” of James J. Hill and his Great Northern Railway.
As Folsom details, the former chased government largesse, ultimately in exchange for loss of control of their business, while the latter chased profits through prudent business decisions. Hill’s success juxtaposed with UP’s and CP’s failure is due in no small part to his steadfast refusal to accept any federal subsidies. In short, UP’s and CP’s government subsidized incentives were vastly different from Hill’s profit driven incentives, which lead to vastly different outcomes.
Federal subsidies incentivized speed, not efficiency. The subsidies were paid in the form of both land grants and direct payments. For each mile of track laid, the UP and CP would receive 20 acres of land and either $16,000 (for track on flat land), $32,000 (for track on hilly terrain), or $48,000 (on mountainous terrain). This incentive for speed resulted in winding, inefficient, routes built with inferior materials, ultimately culminating in a federal price tag of 44,000,000 acres and $61,000,000 (astronomical sums in the 1860s-70s). Despite all this federal assistance, shortly after the golden spike was driven on May 10, 1869 at Promontory Summit, Utah, the UP and CP were nearly bankrupt and required further assistance to stay afloat.
The lines which were born and brought up on federal aid needed federal aid to continue. This led to the passage of the Thurman Law in 1874 which forced UP to pay 25% of its earnings a year to pay its federal debt.
UP’s profitability decisions were also subject to government approval. Branch lines — smaller lines off the main line into rural communities — which could have helped UP’s bottom line, were often not approved by federal bureaucrats. Additionally, the federal Bureau of Railroad Accounts required constant checking of UP’s books. All these measures stifled the ingenuity that UP so desperately needed to make its line profitable. UP quickly found out that the power to subsidize was the power to destroy.
Hill’s line on the other hand was methodically surveyed and built, on the shortest routes possible, with the least gradient possible, and using the best steel and other materials on the market at the time. Rather than political largess, Hill made his decisions based on profit and loss. But, for all the efficiency that Hill built into his line — he was able to transport across the country faster, cheaper, and with less maintenance costs than could the UP and CP — arguably the most important aspect for the viability of his business was the freedom to conduct business untethered by the strings that accompanied government subsidies.
While Hill was free to build when and where he wanted so long as he reached voluntary agreements with landowners, consumers, and employees, UP was tied up in red tape. As Hill’s line grew evermore profitable and reliable for customers, the UP and CP struggled along on federal aid, until they ultimately went bankrupt in 1893.
For his part, Hill’s line was the only transcontinental railroad to never go bankrupt.

QotD: Foucault’s “Ship of Fools”
And so, Foucault tells us, in the fifteenth century there is a sudden emergence of a complex of artistic and philosophical themes linking madmen, the sea, and the terrible mysteries of the world. These culminate in the “Ship Of Fools”:
Renaissance men developed a delightful, yet horrible way of dealing with their mad denizens: they were put on a ship and entrusted to mariners because folly, water, and sea, as everyone then knew, had an affinity for each other. Thus, “Ships of Fools” crisscrossed the seas and canals of Europe with their comic and pathetic cargo of souls. Some of them found pleasure and even a cure in the changing surroundings, in the isolation of being cast off, while others withdrew further, became worse, or died alone and away from their families. The cities and villages which had thus rid themselves of their crazed and crazy, could now take pleasure in watching the exciting sideshow when a ship full of foreign lunatics would dock at their harbors.
This was such a great piece of historical trivia that I was shocked I’d never heard it before. Some quick research revealed the reason: it is completely, 100% false. Apparently Foucault looked at an allegorical painting by Hieronymus Bosch, decided it definitely existed in real life, and concocted the rest from his imagination.
Foucault apologists try to rescue this, say that he was just being poetic in some way. He wasn’t. Page 8 in my copy: “Of all these romantic or satiric vessels, the Narrenschiff [Ship Of Fools] is the only one that had a real existence — for they did exist, these boats that conveyed their insane cargo from town to town.” He really, really doubled down on this point. As far as I can tell, this is just as bad a failing of scholarship as it sounds – and surprising, since everything else about the book gives the impression of Foucault as an incredibly knowledgeable and wide-ranging scholar.
