The Little Racket That Changed Tennis

Friday, September 10th, 2010

Kristina Dell calls it the little racket that changed tennis:

Today, thin is in. Skinny grips and lighter frames that carry more weight in the head rather than the shaft help baseliners generate more racket-head speed so they can use their wrists and forearms to roll through their shots. Updated polyester strings only add to the effect, as players finish their swings with their rackets up around their ears to get crazy amounts of spin.

“If you give Nadal a heavy racket with a big grip, it’s impossible to do what he does,” said Roman Prokes, part of the team of U.S. Open stringers handling Mr. Nadal’s sticks.
[...]
Aside from treating his rackets kindly, what Mr. Nadal does is put a lot of action on the ball. A maneuverable frame lets him execute his signature lefty forehand: instead of following through over his right shoulder, Mr. Nadal snaps his racket back after hitting the ball. (Kind of like a ping-pong player.) The result is a hyper-rotating spin with the ball jumping high off the court.

Rafa’s racket weighs a flimsy 10.6 ounces unstrung, plus an extra 0.4 ounce he adds to the head, for a total of 11.5 ounces with strings, practically pixie dust in the hands of a 6-foot-1 hulking guy. By contrast, the 5-foot-10, 128-pound Caroline Wozniacki, the U.S. Open’s top seeded woman, plays with the same Babolat Aeropro Drive as Mr. Nadal; her frame is just two ounces lighter than Mr. Nadal’s.

If Mr. Nadal picked up Mr. Sampras’s old racket today, his shots would probably hit the fence. The hefty, unforgiving Pro Staff Original Mr. Sampras used en route to 14 Grand Slam titles is 12.6 ounces unstrung. It was already cumbersome, but Mr. Sampras added lead tape to get more power and control, for a total mass of almost 14 ounces with strings. To manage it, he used a grip with a circumference of 4 5/8 inches.

Mr. Nadal’s svelte handle is but a toothpick in comparison: 4¼ inches around, a size smaller than the grip Ms. Wozniacki and many women use. “A 4 3/8 grip was considered a ladies racket,” said Mr. Prokes, “but now across the board players have gone to small grip sizes, at least one size smaller or more.”

What an NFL Training Camp Is Really Like

Friday, September 10th, 2010

Nate Jackson explains what an NFL training camp is really likehell, basically — starting with the obvious point that it hurts:

In a strictly physical analysis, training camp brutalizes the body. The N.F.L. is home to the strongest, most explosive athletes on the planet. Being hit over and over again by these men is a painful ordeal, not so much as it’s happening, but after the fact: after practice, late at night, early in the morning. Morning is the worst.

About three or four days into training camp is when the soreness starts to peak, and it sticks around for about a week and a half until your body starts to desensitize itself to misery. During my six seasons with the Denver Broncos, there were days when getting out of bed was so difficult I was sure there was no way I could practice. Of course I was wrong. I found a way to get it done. Football players learn how to push down the pain and make a play. But it hurts later. It hurts a lot.

Then people yell at you:

The verbal haranguing isn’t exclusive to the field. In meetings every day and night, it continues. The decibel level decreases, but it’s no less biting. Every play of every practice is watched on film by the whole team that same day. [...] Being called out in meetings and having everyone in the room watching you fail in slow motion — often with a laser pointer on your two-dimensional body — is demoralizing, and only intensifies the pain. This scrutiny is well intentioned, but often falls flat from overkill, the message trampled by the messenger.

And then there are the cuts:

Realistically, of the 80 guys on each roster, 15 are already cut. Coaches have a pretty good idea of what the final roster will look like. There’s a little bit of wiggle room in the middle of the depth chart. At every position, there are usually two guys competing for one spot. [...] But this is in the middle of the depth chart, meaning that if a team is carrying 10 receivers in camp, receivers Nos. 5 and 6 are battling for a job. Nos. 7 through 10 are camp bodies, there to bolster the numbers, to take punishment, to give veterans an occasional rest, to serve as verbal punching bags for position coaches trying to make a point.

This happens at every position, even quarterback. Players see this happening to them, and there is nothing they can do about it. At the bottom of the depth chart, guys get very few quality “reps” — repetitions, turns to play in practice. Coaches often encourage these players, saying things like, “Don’t count your reps, make your reps count!” But reality sets in. For many, this will be the last football they will ever play.

America’s weirdest government monopoly

Thursday, September 9th, 2010

The Economist calls it America’s weirdest government monopoly. I don’t know about that, but this analysis does seem a bit weird:

Ever since the end of prohibition in 1934, to buy a bottle of Kentucky bourbon in the state of Virginia, you’ve had to go to a government-run ABC (Alcoholic Beverage Control) store. Republican Governor Bob McDonnell is trying to privatise the system, but is running into opposition in the legislature, because the state liquor monopoly is an important source of government revenue. (Just like in Soviet Russia!) The state makes at least $230m a year from the ABC stores, $110m from taxes and $120m in profit. For a sell-off plan to stay revenue-neutral, it would have to sharply raise taxes on alcohol, including a new tax on alcoholic drinks in restaurants and bars. Mr McDonnell says the sell-off of licenses to wholesalers and retailers would net a one-time revenue of $300m to $500m, which could be invested in transportation infrastructure. But legislators don’t think he’s driving a hard enough bargain.

“If you want more milk, you don’t sell the cow,” said [Democratic delegate Albert] Pollard, the great-grandson of the governor who created the ABC system, John Garland Pollard, who served from 1930-34.

“Any business person knows you ought to sell a business for five to seven times the yearly earnings,” Pollard said, meaning the state should be taking in more than $1 billion in franchise fees. “I don’t see that kind of return there.”

Some experts think it’s impossible for the state to make as much from taxes as it does from its sales monopoly, the Washington Post‘s Rosalind Helderman reported last month. Maryland has liquor prices nearly as high as Virginia’s, but made just $25m in excise taxes last year. A study by the Distilled Spirits Council of the United States found liquor taxes in Virginia would have to reach five times the average in privatised states to keep the revenue stream at current levels.

If the state makes $230m a year from the ABC stores — $110m from taxes and $120m in profit — then it should be able to do one of two things:

  1. It could double the excise tax on liquor. Normally this would drive up the price of liquor and reduce the quantity demanded — and thus tax revenues would not double — but in this case the state is already charging monopoly prices and making monopoly profits. This would simply shift money from state-store profits to state tax revenue — which would leave the state’s finances intact but would leave the about-to-be-privatized liquor stores with low profit potential. They thus would not sell for a high multiple of their current monopoly earnings.
  2. It could leave taxes as they are and sell off the profitable liquor stores. The liquor stores are currently quite profitable and might sell at a decent multiple of earnings — but they’d really sell at a premium if the state credibly promised to restrict liquor licenses. Then buying a store would mean buying a low-risk stream of cash flows — which would be worth far more than five to seven times earnings.

So, if you’re a politician, you threaten to hike excise taxes, sell state stores to your cronies at depressed prices, wisely come to see that excise taxes are regressive and thus bad, and then decide to restrict liquor store licenses instead, to make sure the scourge of liquor does not run wild — and to drive the value of those newly private liquor stores back up.

Early man butchered and ate the brains of children as part of his everyday diet

Thursday, September 9th, 2010

Early man butchered and ate the brains of children as part of his everyday diet, a new study of fossil bones in Spain suggests:

Among the bones of bison, deer, wild sheep and other animals, scientists discovered the butchered remains of at least 11 human children and adolescents.

The bones also displayed signs of having been smashed to get the nutritious marrow inside and there was evidence that the victims’ brains may also have been eaten.

Striek marks on the bone at the base of the skull also indicated that the humans had been decapitated according to the study’s co-author José Maria Bermúdez de Castro.

Bermudez de Castro, of the National Research Center on Human Evolution in Burgos, Spain, told National Geographic: ‘Probably then they cut the skull for extracting the brain. The brain is good for food.’
Scientists believe that early man ate fellow humans both to fulfill his nutritional needs and to kill off neighbouring enemy tribes.

Bones of humans that had been eaten spanned a period of around hundred thousand years, indicating that the practice was not just confined to times when food was scarce.

And the fact that the bones were discarded with those of other animals suggests that there was no religious significance to the practice.

Giant hay bale kills former ELO cellist

Thursday, September 9th, 2010

A giant bale of hay has killed a founding member of the Electric Light Orchestra (ELO) after it tumbled down a hill and crashed into his van:

Cellist Mike Edwards, 62, died after the 600 kg (1,323 lb) bale rolled down a steep field in Devon, southern England, smashed through a hedge and careered on to the road.

He died instantly in the freak accident on Friday afternoon.

Police said they used photographs and YouTube footage to identify Edwards and are investigating whether the bale may have fallen from a tractor working on farmland near the road.

Edwards, who played with the band between 1972 and 1975, is believed to have swerved into another vehicle as the bale crushed his cab.

Here he is playing casually just last year:

Microwave-Powered Rocket Ascends without Fuel

Thursday, September 9th, 2010

Traditional chemical rockets are 90 percent fuel by weight:

In the beginning of the 20th century, it occurred to Russian rocket scientist Konstantin Tsiolkovsky that there was another way: by keeping the energy source on the ground and beaming the required power to a rocket, it could be launched with very little fuel on board.

With the invention of the maser, or microwave laser, scientists were granted a tool to realize Tsiolkovsky’s dream. So in the 1970′s they began to model just what it would take. Some were optimistic about its potential to decrease the cost of going to orbit by orders of magnitude, but the bottom line is that, for a lack of funding, the technology never took off.

The Japanese recently demonstrated (another) prototype microwave-powered rocket:

The latest demonstration used a Gyrotron — essentially a maser — at the Naka Fusion Institute of the Japan Atomic Energy Agency. (This super high-powered microwave beam emitter was originally developed as part of Japan’s contribution to ITER, the international effort to create a workable fusion reactor.)

Using this beam, the scientists were able to send pulses of microwave energy into the bottom of their hollow 126 gram rocket model, heating the air within to 10,000 degrees Celsius and resulting in its rapid expansion. The result is a little boom, “like thunder,” they report.
[...]
The rocket traveled 1.2 meters into the air — the world record for such a craft is 72 meters and 12.7 seconds of flight, accomplished in 2001.

Advance in Quest for HIV Vaccine

Wednesday, September 8th, 2010

U.S. government scientists say they have discovered three powerful antibodies, the strongest of which neutralizes 91% of HIV strains:

They are now deploying the technique used to find those antibodies to identify antibodies to influenza viruses.

The HIV antibodies were discovered in the cells of a 60-year-old African-American gay man, known in the scientific literature as Donor 45, whose body made the antibodies naturally. The trick for scientists now is to develop a vaccine or other methods to make anyone’s body produce them as well.

The Real Stuff White People Like

The Fastest Helicopter on Earth

Wednesday, September 8th, 2010

Thomas Lawrence, a technical fellow at Sikorsky, made a career of peculiar projects before successfully developing the fastest helicopter on Earth, the X2:

First he helped design an airship lifted by four conjoined helicopters. Next came the XH-59A, a futile effort to break the helicopter speed record. He then focused on the X-Wing, an aircraft that could take off like a helicopter but switched midair to fly like a fixed-wing airplane. None succeeded. Before turning to the very successful X2, Lawrence says, “I wasn’t sure what my career path was.”

The X2 has unofficially reached 435 km/h, and should soon officially break the 400 km/hr record set by a modified Westland Lynx. A typical helicopter can reach 270 km/h — with some difficulty:

Compared with the fixed wings of an airplane, a helicopter’s rotating blades make for a much more complicated design. Each blade must withstand the forces of rotation, which can amount to many times the weight of the aircraft on each blade. A helicopter also needs a powerful engine and a large transmission to reduce the engine’s rotation rate to something appropriate for the large rotors. For example, a U.S. Army UH-60 Black Hawk engine’s output of 20 900 revolutions per minute turns the main rotor only 258 times per minute, a ratio of 81 to 1.

But here’s the catch. When a helicopter flies forward, the rotor blades experience a dramatic variation in airspeed. That’s easy to see if you imagine a miniature version of yourself perched on the tip of a helicopter rotor blade. If the helicopter were hovering, you’d feel a constant 800-km/h wind in your face as the rotor spun around. If the helicopter were to fly forward, you would note that the wind was stronger on what’s called the advancing side, when the rotor was moving in the same direction as the helicopter, but that it would be noticeably weaker when the rotor was on the retreating side. By the time the helicopter reached 150 km/h, you would feel a wind speed of 950 km/h on the advancing side, versus 650 km/h on the retreating side. The relative speed of the wind on the retreating side gets lower and lower the faster the aircraft flies. At 300 km/h, the wind on the advancing side would reach 1100 km/h, while the wind on the opposite side would be 500 km/h.

Eventually, the helicopter would reach a point at which the difference between the lift on the advancing and retreating sides of the rotor could not be balanced and the vehicle wouldn’t be able to maintain level flight. To complicate matters further, portions of the tip of a fast-flying helicopter’s advancing blade can exceed the speed of sound, producing shock waves that cause large vibrations and generate considerable noise. For these reasons, most helicopters just don’t like to go fast.

There’s more than one way to skin a cat:

In the 1950s, aircraft designers began to look at other configurations to achieve vertical takeoff and landing and reach forward speeds greater than 450 km/h. One approach was to design an aircraft whose thrust could be tilted vertically for takeoff and landing and horizontally for forward flight, during which time the vehicle would produce its lift from fixed wings. Some, such as the Bell X-22, used tilting ducted fans, while others used tilting propellers—for example, the Vought-Hiller-Ryan XC-142A and Canadair CL-84. Some had tilting jet engines, like the EWR VJ 101C. All handled poorly when hovering and produced downward air velocities high enough to blow a house down and uproot trees.

A more successful variation on this theme is the tilt-rotor, which uses helicopter-like rotor blades instead of ducted fans or propellers, with the axis of rotation switching from vertical to horizontal after takeoff. But this dual use is awkward: The rotors are too small for the aircraft to hover efficiently and larger than optimal for forward flight. The complicated tilting mechanism and excessive amount of power it requires also make the tilt-rotor option costly and complex.

Another approach to high-speed vertical takeoff used specially designed lift engines that worked only during takeoff and landing. These heavy engines produced large thrust for vertical takeoff and landing; in forward flight they were shut down and covered by doors. One such vehicle, the Dassault Mirage IIIV, was able to reach Mach 2, twice the speed of sound. Unfortunately, if you were on your roof waiting to be rescued, such an aircraft might not only fail to retrieve you, it could set your house on fire.
Aircraft engineers have also tried out jet engines with adjustable exhaust nozzles. The Hawker Siddeley Kestrel, which first flew in 1960, could aim its thrust in different directions, making the aircraft quite agile in forward flight and able to take off and land vertically. But the exhaust was again too hot and fast for the helicopter to be suitable for rescue purposes.

What we at Sikorsky settled on almost four decades ago was a design we called the Advancing Blade Concept. It uses two counterrotating rigid rotors that spin around the same axis, which is why they are known as coaxial rotors. In forward flight, each rotor produces a surfeit of lift on its advancing side, freeing the retreating side from having to do any heavy lifting, all while maintaining good balance. Sikorsky patented the concept in 1964, but considerable engineering was needed to actually get something like this in the air.

Terra-Forming Ascension Island

Tuesday, September 7th, 2010

When Charles Darwin set sail aboard HMS Beagle for Ascension Island from the nearby volcanic island of St. Helena, the locals set his expectations quite low:

“We know we live on a rock, but the poor people of Ascension live on a cinder.”

Seven years later, Darwin’s friend, botanist Joseph Hooker, called in on Ascension Island after sailing around Antarctica aboard HMS Erebus and Terror — and started terra-forming the island.:

Ascension was a strategic base for the Royal Navy. Originally set up to keep a watchful eye on the exiled emperor Napoleon on nearby St Helena, it was a thriving waystation at the time of Hooker’s visit.

However, the big problem that impeded further expansion of this imperial outpost was the supply of fresh water.

Ascension was an arid island, buffeted by dry trade winds from southern Africa. Devoid of trees at the time of Darwin and Hooker’s visits, the little rain that did fall quickly evaporated away.

Egged on by Darwin, in 1847 Hooker advised the Royal Navy to set in motion an elaborate plan. With the help of Kew Gardens – where Hooker’s father was director – shipments of trees were to be sent to Ascension.

The idea was breathtakingly simple. Trees would capture more rain, reduce evaporation and create rich, loamy soils. The “cinder” would become a garden.

So, beginning in 1850 and continuing year after year, ships started to come. Each deposited a motley assortment of plants from botanical gardens in Europe, South Africa and Argentina.

Soon, on the highest peak at 859m (2,817ft), great changes were afoot. By the late 1870s, eucalyptus, Norfolk Island pine, bamboo, and banana had all run riot.

Oliver Sacks on Vision

Tuesday, September 7th, 2010

Steve Silberman interviews Oliver Sacks (Awakenings, The Man Who Mistook His Wife for a Hat, and An Anthropologist on Mars), on his new book, The Mind’s Eye, and his recovery from cancer of the eye:

Silberman: In the book, you go on to describe some fascinating experiments you performed on your own vision, where you observed your brain “filling in” the blank spots in your visual field with patterns and hallucinations. The naive view of our visual system is that it works like a camera, passively receiving sense impressions and compiling them in the brain into a more or less accurate picture of the world. But the work of researchers like V.S. Ramachandran and many others has led us to understand that vision is a highly active and even speculative process, with the brain making guesses and predictions about what the eyes can’t see.

In the course of your illness, you discovered that your brain would generate elaborate patterns, even clouds or leaves, to hide the blank space in your vision caused by the tumor. You’ve always been interested in the brain’s generative visual activity — whether caused by illness or psychedelics — and wrote about it at length in your first book, Migraine. But what did you learn from these experiences about how the brain creates a seemingly seamless world out of fragmentary sense impressions?

Sacks: In general terms, I learned that the brain is always busy. In particular, if a sensory input — whether it be vision or hearing or kinesthesia — is taken away, there will be some sort of compensation, and the cortical systems involved in those representations will become hyperactive. This first became clear to me when I spoke to various blind people. One man, for example, who had lost his sight when he was about 20, said that when he read Braille, he didn’t feel it in his fingers, he saw it. And there’s nice evidence that the occipital areas of the brain, and the inferotemporal areas — visual areas — are excited in that sort of situation.

For myself, I was very struck by this “filling in” business. The first thing that struck me was when I was in hospital and I could pay more attention to these things — perhaps too much attention. But the scotoma in my vision, the blind area, was almost like a window looking into a landscape. I could see movement, and people, and buildings in it — things like those my brain concocts while I’m falling asleep or before a migraine. But this seemed to be going on continuously.

And then there was an episode that very much startled me. Kate was in the room at the time too. I was washing my hands, and then for some reason I closed my left eye, and I continued to see the wash basin, the commode next to it, and the mirror very, very clearly — so clearly, in fact, that my first thought was that the dressing over the right eye must be transparent. But it was a huge, thick, opaque dressing. This was something quite different from an after-image. It was more like a strange persistence or perseveration of vision. The image wasn’t being erased in the usual way.

But this sort of thing really only hit me after I had been lasered in June of ’07 and lost my central vision. Then the night I took off the bandage, I saw this great black amoeba — this thing shaped like Australia — but when I looked up at the ceiling, it immediately disappeared. It turned white and became camouflaged by taking on the color of its surroundings. I then found that I could fill it in with simple patterns, like the repeating geometric pattern on my carpet.

Then I discovered another phenomenon which astounded me. Later that month, I went to Iceland for a friend’s wedding. Coming back on the plane, it was very hot, so I took off my shoes and socks. I liked playing with the scotoma, moving it around and putting things “into” it, so I used it to amputate my leg mid-shin. But then I started wiggling my toes, and gradually there was a strange, pinkish, protoplasmic extension around the stump of my leg. This formed itself into the shape of a foot with wiggling toes, and followed all my movements exactly. It didn’t look quite real — it had no skin texture or whatever — but it really was an astounding phenomenon, and made me feel that the visual area had become hypersensitive to other inputs, such as proprioceptive input or some sort of motor afferent.

I also had — and still have — almost continuous hallucinations of a low order: geometric things, especially broken letters, some of them like English letters, some like Hebrew letters, some like Greek, some runes, and some a bit like numbers. They tend to have straight lines rather than curves, but they rarely form actual words. This is not something I said in the book, but if I smoke a little pot, they sometimes become words. And they tend to be in black and white — but when I smoke a little pot, they’re in color.

Mass mysticism, moving with modern arms

Monday, September 6th, 2010

As Hilaire du Berrier explains in Background to Betrayal, Vietnam had a number of factions vying for power, not just Communists and anti-Communists. The Cao Dai sect stands out as even more colorful than the Robin Hood-like Binh Xuyen bandits of the swamps:

As for the Cao Dai, it was French General de la Tour who approved bringing into the war against Ho chi Minh the private army of the Cao Dai pope.

The Vietminh were like water; they were everywhere and nowhere. The country was their sponge, and de la Tour decided to wrest a cleared space from the fluid enemy. De la Tour had informers by the thousands. The intelligence service of the French army spent piastres by the millions. Information was exchanged and traded on a regular market, but most of it was false. The truth was too dangerous. Leaks invariably led to the honest informer’s getting his throat cut.

So in 1948 the same Cao Dai forces that had in 1945 embarked on a massacre of the French at the behest of the Japanese were brought into the fight as allies against the Vietminh.

In 1945 the Japanese had armed the Cao Dai and moved their flying columns into Saigon when defeat became inevitable. Cao Dai leaders never doubted for a minute that if all the foreigners in Cochin China [Southern Vietnam] had their throats cut, the country would fall to them. The screams that punctuated that frightful night in the spring of 1945 in Saigon will never be forgotten by the Europeans who survived it.

Yet the Cao Dai pope seemed such a gentle little man when one sipped tepid champagne with him at ten in the morning! He was known as His Holiness, Pope Pham cong Tac. Beside him, in immense dignity with his flowing beard, sat the Bao Dao, defender of the faith, the last time the author visited them in their place of exile in Pnom Penh, Cambodia.

The world of the little Vietnamese is inhabited by strange spirits. Everywhere about him is a sense of mystery, and before the mystery his impulse is to band together with other Vietnamese to from a brotherhood bound by inner secrets expressed in obscure symbols. Because the all-seeing eye became one of the symbols of the Cao Dai sect, students of occult societies have attempted to link Vietnam’s powerful sect with older orders and offshoots of the Illuminati. Actually, to do so is to accord it a genealogy it does not have.

The men who sat around Ngo van Chieu’s table in 1919 while he communicated with the spirits by means of the “corbeille à bec,” a primitive, beak-shaped gadget holding a pencil which in the hands of the adept communicated the daily message, were minor functionaries with at least rudimentary French educations. Victor Hugo was the literary giant of their class, so it was only natural that he should communicate with them. The symbol of the all-seeing eye was familiar to them. They had read of the Grand Orient lodge of the Free Masonry in their French history.

Long before the master with whom they were in contact identified himself on Christmas Eve of 1925 as “Cao Dai, the Pure August One, the Oldest of the Buddhas, Sakyamuni and Jesus Christ,” Chieu had plundered the Grand Orient of its symbol, without any deep knowledge of that secret lodge or any other.

When Chieu got back to Saigon his first important convert was a hard-drinking, wildly gambling reprobate named Le van Trung, who overnight threw himself into Cao Daism with such fervor that he seized its direction from Chieu. Trung became the sect’s first pope. Till his death, or “disincarnation” in Cao Dai phraseology, in 1934, the sect never ceased to expand. Then came Pham cong Tac, the former customs official.

Asia was in a state of flux. The nha-que, the toiling little man of Asia’s human anthills, was rejecting many of his old superstitions. And Pope Pham cong Tac was a genius at administration. His discipline and leadership hardened the organization. Disjointed bands had protected the sect against incursions by Vietminh guerrillas and the French. Pham con Tac welded them into an army, the only army outside the Vietminh that possessed all the elements necessary for a crusade: a mysticism, an ideal, a large following, a cohesive organization and courageous fighters. In sum, an instrument of domination.

And Cao Dai ambitions were boundless. To push ahead, to gain more strength, to possess more followers, to control more ground, to acquire more wealth, by duplicity, treachery, brutality or religion, was their aim.

Political organizations were suppressed by the French police, but police were powerless against a religion. Under Pope Pham cong Tac the Cao Dai followers bled the Japanese for money as a special auxiliary force. Prince Cong De, a cousin of Bao Dai, was brought back from Japan to serve as a puppet, and the Cao Dai were hired to acclaim him. Without a qualm they swung over to Cong De as long as the money lasted. From the Japanese they swung to the Vietminh, till the Vietminh threatened the Cao Dai pope; then they became the allies of the French, and their holy see of Tay Ninh, with it great Cao Dai temple, became a pillar in the anti-Vietminh struggle.

Delirious bands, impervious to danger and fighting as though under a hypnotic spell, out-fought the chidois (sectors) of the Vietminh wherever they found them. Soldiers of the pope were suicides from the moment they started. They killed, and died as they killed, as though life were of no importance. If the French suffered an ambush, word was sent to the Cao Dai pope and a flying brigade cleared the area. What they did with their prisoners the French never knew. Some were herded back in columns, closely guarded lest the Vietminh try to liberate them. At the end of each column marched security officers. Between vehicles moved the shock troops. In the center came mortar bearers, accompanied by their ammunition coolies. Pushed on by bayonets were the prisoners, assassination squads of the Vietminh. The villages they had terrorized henceforth belonged to the Cao Dai.

On either side of the route of march, phantoms moved through the brush, scouts by the hundreds armed only with a hand grenade to protect the flanks and alert the column in the event of attack. Along the road an efficient alarm system operated.

It was mass mysticism, moving with modern arms. When a French general could not find the enemy he had only to call on the Cao Dai pope. A lying brigade would be dispatched, and in three months they would have a fort, the Vietminh would be gone — wiped out to a man. The nha-ques, the country people, converted to Cao Daism, would be working as spies or toiling as Cao Dai slaves to feed and serve the new organization.

Each time a Vietminh drive threatened a pacified area, France’s General de la Tour had only to give the Cao Dai a bit more money, a few more machine guns, and Vietminh implantation was succeeded by that of the Cao Dai.

In the end the general realized that in areas where the Vietminh had been, a new problem presented itself. Every youngster playing beside a road, every workman in a field, the woman selling produce or weaving a basket, the decrepit beggar lying beside a tree — every human being, no matter how young or old, how weak or humble — was against the Vietminh but also against the French. When the general staff realized this, the delicate game of balance and counterbalance started.

The Cao Dai sect recognizes three saints: Sun Yat-sen, Victor Hugo, and Nguyen Binh Khiem.

5 foods it’s cheaper to grow

Sunday, September 5th, 2010

William Alexander did the math and realized that his garden tomatoes were costing him $64 to grow:

The title says it all, but the dirty details reveal he spent $16,565 building the perfect garden and $735 maintaining it for one year. Amortizing the initial costs over 20 years, adding this year’s expenses and dividing the result among all his produce, he figured his 19 Brandywine tomatoes cost $64 apiece.

Here are five crops that are cheaper to grow than to buy at the store:

  • Fruit trees. If you really want a return on your garden investment, plant fruit trees. Alexander planted one $14 peach tree, and it gives him more than 200 pounds of peaches every year. Yes, he sprays it every year with about $3 worth of fungicide and pesticides. (The sprayer cost $30.) In the Hudson Valley, he doesn’t have to water fruit trees. At $1 per pound for the peaches, in the first year that he got a full crop, he had a 1,400% return (or a mere 339% if you throw in the cost of the sprayer and a few years’ worth of spray). Try getting a return like that on Wall Street. It took Alexander five years to get a full crop, so it does require patience.
  • Lettuce. Can’t wait five years for results? Try lettuce. You’ll be eating the thinnings in two or three weeks. From a $2 package of mixed lettuce seed, you can have lettuce for months. A bag of spring greens costs about $3 at a store, so you recoup your investment with the first picking. Lettuce bolts — goes to seed — during the summer heat, so plant again in the fall.
  • Herbs. These can give you the fastest payback of all. Buy a pot of parsley or mint and you can nibble on leaves on the way home. A parsley plant costs about the same amount as a bunch of cut parsley from the produce department. Parsley in a pot, kept out of reach of slugs, will provide fresh herbs all summer and can be brought inside in the fall. Thyme, rosemary, sage and other herbs come back on their own year after year in moderate climates.
  • Vine vegetables. These are the most prolific crop producers by far. Zucchini and cucumbers are notorious. Put an 88-cent zucchini plant in your garden and, if cutworms don’t get it, it will try to take over the neighborhood. In most parts of the country, you can grow more zucchini from one plant than you’ll ever eat. The Alexanders grow a couple of cucumber plants, from which they make a dozen jars of pickles. They never buy pickles.
  • Bell peppers. You can pay $1.50 for one pepper, or you can use your $1.50 to buy one pepper plant that can produce six peppers or more. But first make sure peppers will grow in your part of the country.

Here are five more that are better left to the real farmers:

  • Potatoes. Homegrown spuds are great, but by midsummer, farmers are almost giving them away. Alexander says, “For the $30 I spent on seed potatoes this year I could probably buy 100 pounds of white potatoes in August (and trust me, my harvest won’t be anywhere near 100 pounds).”
  • Carrots. Carrots are popular, but they grow slowly and are fussy about soil conditions. Carrots in grocery stores are cheap and taste about the same.
  • Celery. This vegetable doesn’t like sand or clay, requires plenty of water and grows slowly. Steve Solomon, in “Gardening When It Counts,” says he considers regular celery one of the “difficult” vegetables to grow. He recommends easier-to-grow Chinese, or cutting, celery.
  • Asparagus. Solomon also considers it to be difficult. If you’re looking for a fast payback in the garden, asparagus is not for you. Asparagus requires the right mulch at the right time and weed-free beds. (It’s doomed at my house!) You might get some asparagus the second year, but it can take several years to get a real crop.
  • Wheat. You can buy a 50-pound bag of whole-wheat flour for $62. Other grains and dried beans can also be purchased more easily than they can be grown. Alexander grew almost 20 pounds of wheat from two packets of seed that cost next to nothing — except about 40 hours of backbreaking, never-again labor. Don’t try to compete with thousand-acre farms with combines.

America’s African Rifles

Saturday, September 4th, 2010

Robert Kaplan calls them America’s African Rifles, native troops in Niger trained by American Marines:

Baker’s men had just begun training three platoons’ worth of host-country soldiers, individually selected by their commanders for talent and motivation. Nothing fancy here. The initial training cycle consisted of the fundamentals of good soldiery: shooting, land navigation, and basic medicine. Liberty demands authority; without minimal order there can be no freedom. If Niger’s civilian government was going to survive and protect its borders against transnational terrorists, military professionalization was crucial — and it started in part with Baker’s Marines.

I spent my first days at Tondibiah on the rifle range, watching Nigerien troops being trained by four Marines: Gunnery Sergeant Eric Coughlin, of Shohola, Pennsylvania; Staff Sergeant Stephen Long, of Irmo, South Carolina; Staff Sergeant Bobby Rivera, of the Bronx, New York; and Sergeant Chris Singley, of Milledgeville, Georgia. All were in their thirties except Singley, who was twenty-five.

I have spent enough time with Marines around the world to know that these four had to be an impressive bunch. Noncoms are the heart and soul of the Marine Corps, which may have the most powered-down command structure of any Western military force. Battlefield expertise and leadership depend on sergeants’ leading corporals, who in turn lead lance corporals. Without advanced training one doesn’t get to be a sergeant — particularly a staff sergeant, who commands a platoon of two dozen men, or a gunnery sergeant, the exalted go-to guy in every unit. These Marines were experts: Coughlin was a specialist in military mountaineering, Long in marksmanship, and Singley in riverine operations. As for Rivera, he was a member of Force Recon — something of a Marine equivalent to the Navy SEALs and the Army’s Delta Force. Rivera and Singley were on loan from the Special Operations Training Group, at Camp Lejeune. Because training Third World armies was for decades a Special Forces affair, the deployment to Chad and Niger constituted an opportunity for the Marines to show what they could do, and the Corps had therefore sent some of its best. (Indeed, a few months later Singley — the youngest and least experienced of the four — would be the senior adviser to an Iraqi army unit on the outskirts of Fallujah.)

It was dark and pouring rain at 6:00 A.M., when we set out for the range. First we halted at the Nigerien barracks to collect the trainees. When we arrived, twenty-three of them were standing in formation, singing a traditional morning melody for their commander. After they finished, they climbed in a silent, orderly manner into the backs of our pickups. A few minutes later, when we got to the firing range, they marched out onto the field and began setting up the targets; then they lined up single file, their field caps in their hands as the rain fell on their heads. After prying open the Chinese-made sardine cans of 7.62mm ammunition for the Nigeriens’ AK-47s, Coughlin and the three other sergeants dumped the rounds into the trainees’ field caps. “Wait till the end of the day,” Long told me. “They’ll actually pick up the brass cartridges on the field without being told to — and not to sell, either. They bring their own medical equipment to the range. The Chadians weren’t like this.” The Nigeriens, I noticed also, displayed real muzzle awareness: when not shooting they kept their rifles pointed at the ground, and never once dropped them in the dirt. The Filipino and Colombian soldiers I had observed hadn’t been nearly as disciplined.

The Nigerien military had participated in messy, violent peacekeeping missions in Cote D’Ivoire, Sierra Leone, Liberia, Burundi, the Congo, and Haiti. It was a military that formed its own elite social class, with officers sending their young sons to cadet schools. Its soldiers had proved their willingness to die in defense of not only their own but also U.S. interests: on several occasions Nigerien units had hotly pursued Salafist extremists across the border into neighboring countries.

Waiting around, watching the host-country troops load their ammo into the magazines, I mentioned to Staff Sergeant Long that coups, being a feature of modernization, tend to happen when a military is more institutionally advanced than its civilian authority. Long, a stocky, red-haired thirty-two-year-old with piercing eyes, who had been tagged for me by Major Baker as one of the brightest Marines in the unit, broke in about the Filipino military and the inefficiency and corruption of successive civilian regimes in the Philippines. His insights were impressive. As Baker’s remarks about Chad and Niger had shown, Marines suck up knowledge wherever they can. And because their personal experiences are so different from those of journalists and academics, their company is invigorating in an intellectual sense.

Dawn came, and for a time the rain held off the heat. I inserted my earplugs and joined the Americans and the Nigeriens as they walked out onto the 300-yard range. It was good to be on a rifle range again. In 2003 and early 2004 I had taken a crawl-walk-run approach to following the U.S. military. I observed Army Special Forces training host-country troops in Colombia and the Philippines, and then accompanied them on presence patrols and armed assaults in Afghanistan; I observed Marines in training and pulling guard duty in Djibouti, and then accompanied them during urban combat in Iraq. This approach required regularly going back to the basics, just as soldiers themselves always do; the circular monotony of military life is fundamental to any experience of it. When Special Forces and Marine battalions return from deployments overseas to Fort Bragg, North Carolina, or Camp Pendleton, California, they return to the rifle range. With the training of indigenous troops at the heart of imperialism, and the rifle range at the heart of such training in our era, the range is truly the center of it all.

“Every time you fire, a bad guy should bleed!” Sergeant Rivera yelled. “Aim for the high center torso. Any hit is good. Don’t worry about carving up the bull’s-eye. This isn’t target shooting. It’s about fighting with a gun.” He spoke with a Bronx accent, his voice at once loud, grating, and intimate. Because Rivera was a specialist in weaponry and the related field of close-quarters combat, Coughlin — who, as Gunny, technically outranked him — deferred to him.

A Nigerien major, Moussa Salou Barmou, translated Rivera’s commands into French and Hausa for his soldiers. Major Moussa had trained with the U.S. Army at Fort Benning, Georgia, and with the Ivorians, the Cameroonians, and the Pakistanis. “I didn’t know what real combat was about until Fort Benning,” he told me. “The Americans have the money to simulate war in training, unlike other armies. But I wish the Americans could see how the rebels settle in our border towns in the desert and marry local girls so that they become invisible, so that you don’t know who you have to fight.” Because Major Moussa outranked the Marine noncoms, each made sure to address him as “Sir.”

Rivera went on. The Nigeriens were only fifteen yards out from the targets — paper silhouettes of soldiers aiming their guns. “You will all fire a controlled pair followed by a hammer,” he explained. “A controlled pair is two slow shots. A hammer is two fast ones. Shooting a hammer, the rifle will recoil twice. You won’t have time to readjust, meaning with a fucked-up body position you will miss the target at least once. And that” — he was now shouting — “is unacceptable!”

Rivera demonstrated, repeating and yelling everything, sometimes mixing English with French in his Bronx accent: “En position. Levez la sécurité. Feu! Avancez.” Meanwhile, Coughlin, Long, and Singley worked quietly with individual soldiers. Major Moussa did his part, in one case shoving his knee behind that of one of his soldiers to ease him into the correct body position. I remembered a young Filipino lieutenant who constantly had to be told by an American noncom to pay attention to his own troops. That wasn’t necessary here.

Rivera now made them repeat the drill from twenty-five yards out, this time while changing magazines: “Don’t bend down. Just let the magazine drop. Minimize your movements or you’re gonna fucking die.” He demonstrated shooting and changing magazines while closing the distance from twenty-five to fifteen yards. The impressive thing was what wasn’t happening: there were no wasted movements. “Notice,” he said, “I’m not fast. I’m just smooth. It’s not about speed but about efficiency.”

Later he taught them how to unjam their AK-47s while also changing magazines and closing the distance with the enemy. “This isn’t target practice!” he kept shouting. “This is about killing people!” During the entire morning Rivera only once checked the targets to see how accurately the soldiers were shooting. As long as they were hitting the silhouettes or just the paper, he was happy. He wanted them to be comfortable handling a rifle on the move in combat. He knew from assaults on mud-walled compounds in Afghanistan during the first weeks of the U.S.-led invasion there, in 2001, that survival was less a matter of a perfect shot than of getting a spare magazine quickly out of a side pocket.

Rivera liked the fact that the targets were man-shaped silhouettes rather than concentric circles. “If you’re aiming at a bull’s-eye, you’re being programmed to shoot paper. If you’re aiming at a silhouette, you’re being programmed to kill motherfuckers.”

“Standing is the most unstable platform for firing a rifle,” he went on. “That’s why fifty yards out is the farthest we will ever shoot standing up. At a hundred yards I’ll drop to the prone in two seconds, but then I’ll methodically put two in his chest so the motherfucker will die before he can find his iron sights. That way I’ll live. And I wanna live, because back in America there are a lot of women that love me.” Major Moussa translated, and his soldiers laughed loudly.

When Quality Doesn’t Matter

Friday, September 3rd, 2010

Back when the Web was young, Paul Graham demonstrated a new algorithm to Yahoo’s Jerry Yang, one that ranked search results by user behavior and differentiated between clicks and clicks leading to purchases.  Yang didn’t seem to care, and this confused Graham:

I was showing him technology that extracted the maximum value from search traffic, and he didn’t care? I couldn’t tell whether I was explaining it badly, or he was just very poker faced.

I didn’t realize the answer till later, after I went to work at Yahoo. It was neither of my guesses. The reason Yahoo didn’t care about a technique that extracted the full value of traffic was that advertisers were already overpaying for it. If they merely extracted the actual value, they’d have made less.

This, Eric Falkenstain notes, is just one example of when quality doesn’t matter:

There are many stories about real-estate brokers setting up shop in the early aughts, not caring about whether homebuyers would actually pay their mortgage because it did not matter. This was a signal that rot was rampant. Basically, if quality doesn’t matter, and there’s free entry, there’s a bubble.

When people have positions that don’t do what they say they do, and make a lot of money, there are myriad bad effects. Once when I was a risk manager, I remember showing a swaps book trader a more efficient way for him to hedge his portfolio. As I had to calculate his value-at-risk I had all the data to demonstrate conclusively my superior algorithm. He found this annoying. As a market maker, his Sharpe was already well above 10, so decreasing his value-at-risk by 20% did not really matter. Like Graham’s encounter, I discovered it was all marketing.

The problem with this situation is that when you really understand the game, you have to never talk about it, which is easiest to do if you really don’t understand it. So, the best brokers or brokers-who-call-themselves-traders are blithely ignorant, because they don’t generate ‘tells’ that make everyone engaging in the game uncomfortable. When they talk about trade ideas that are totally unfounded, they can’t be convincing if aware of its lack of statistical evidence, or how their qualifications make everything said meaningless (this could lead to a retracement). Once you swallow the red pill, you can’t go back to enjoying the Matrix.

Similarly in the corporate borg, especially in places like the new Office of Minority and Women Inclusion that is now mandated to be part of each of our 30(!) financial regulatory bodies. As true discrimination is about as rare as a Klan rally, this is all just a sop to the Indian-like ethnic group spoils system the US is becoming (are there really any bankers who hate minorities enough to forgo extra profits?). So, the Chief Diversity officer’s real role is not to rid financial discrimination, but rather to spout cliches about diversity, and put a pretext on the patronage daisy-chain that led to the 2008 housing crisis. However, if you really understood this, you would go crazy, so earnest dolts plague the aristocracy because the dupes actually believe their job is about what it says it’s about.
