Huck Finn caged

From Nicholas Carr’s “Sivilized” (Rough Type: 27 June 2009):

Michael Chabon, in an elegiac essay in the new edition of the New York Review of Books, rues the loss of the “Wilderness of Childhood” – the unparented, unfenced, only partially mapped territory that was once the scene of youth.

Huck Finn, now fully under the thumb of Miss Watson and the Widow Douglas, spends his unscheduled time wandering the fabricated landscapes of World of Warcraft, seeking adventure.

Various confidence scams, tricks, & frauds

From “List of confidence tricks” (Wikipedia: 3 July 2009):

Get-rich-quick schemes

Get-rich-quick schemes are extremely varied. For example, fake franchises, real estate “sure things”, get-rich-quick books, wealth-building seminars, self-help gurus, sure-fire inventions, useless products, chain letters, fortune tellers, quack doctors, miracle pharmaceuticals, Nigerian money scams, charms and talismans are all used to separate the mark from his money. Variations include the pyramid scheme, Ponzi scheme and Matrix sale.

Count Victor Lustig sold the “money-printing machine” which could copy $100 bills. The client, sensing huge profits, would buy the machines for a high price (usually over $30,000). Over the next twelve hours, the machine would produce just two more $100 bills, but after that it produced only blank paper, as its supply of hidden $100 bills would have become exhausted. This type of scheme is also called the “money box” scheme.

The wire game, as depicted in the movie The Sting, trades on the promise of insider knowledge to beat a gamble, stock trade or other monetary action. In the wire game, a “mob” composed of dozens of grifters simulates a “wire store”, i.e., a place where results from horse races are received by telegram and posted on a large board, while also being read aloud by an announcer. The griftee is given secret foreknowledge of the race results minutes before the race is broadcast, and is therefore able to place a sure bet at the wire store. In reality, of course, the con artists who set up the wire store are the providers of the inside information, and the mark eventually is led to place a large bet, thinking it to be a sure win. At this point, some mistake is made, which actually makes the bet a loss. …

Salting or to salt the mine are terms for a scam in which gems or gold ore are planted in a mine or on the landscape, duping the greedy mark into purchasing shares in a worthless or non-existent mining company.[2] During the Gold Rush, scammers would load shotguns with gold dust and shoot into the sides of the mine to give the appearance of a rich ore, thus “salting the mine”. …

The Spanish Prisoner scam – and its modern variant, the advance fee fraud or Nigerian scam – take advantage of the victim’s greed. The basic premise involves enlisting the mark to aid in retrieving some stolen money from its hiding place. The victim sometimes believes he can cheat the con artists out of their money, but anyone trying this has already fallen for the essential con by believing that the money is there to steal (see also Black money scam). …

Many conmen employ extra tricks to keep the victim from going to the police. A common ploy of investment scammers is to encourage a mark to use money concealed from tax authorities. The mark cannot go to the authorities without revealing that he or she has committed tax fraud. Many swindles involve a minor element of crime or some other misdeed. The mark is made to think that he or she will gain money by helping fraudsters get huge sums out of a country (the classic Nigerian scam); hence marks cannot go to the police without revealing that they planned to commit a crime themselves.

Gold brick scams

Gold brick scams involve selling a tangible item for more than it is worth; named after selling the victim an allegedly golden ingot which turns out to be gold-coated lead.

Pig-in-a-poke originated in the late Middle Ages. The con entails a sale of a (suckling) “pig” in a “poke” (bag). The bag ostensibly contains a live healthy little pig, but actually contains a cat (not particularly prized as a source of meat, and at any rate, quite unlikely to grow to be a large hog). If one buys a “pig in a poke” without looking in the bag (a colloquial expression in the English language, meaning “to be a sucker”), the person has bought something of less value than was assumed, and has learned firsthand the lesson caveat emptor.

The Thai gem scam involves layers of con men and helpers who tell a tourist in Bangkok of an opportunity to earn money by buying duty-free jewelry and having it shipped back to the tourist’s home country. The mark is driven around the city in a tuk-tuk operated by one of the con men, who ensures that the mark meets one helper after another, until the mark is persuaded to buy the jewelry from a store also operated by the swindlers. The gems are real but significantly overpriced. This scam has been operating for 20 years in Bangkok, and is said to be protected by Thai police and politicians. A similar scam usually runs in parallel for custom-made suits.

Extortion or false-injury tricks

The badger game extortion is often perpetrated on married men. The mark is deliberately coerced into a compromising position, a supposed affair for example, then threatened with public exposure of his acts unless blackmail money is paid.

The Melon Drop is a scam in which the scammer will intentionally bump into the mark and drop a package containing (already broken) glass. He will blame the damage on the clumsiness of the mark, and demand money in compensation. This con arose when artists discovered that the Japanese paid large sums of money for watermelons. The scammer would go to a supermarket to buy a cheap watermelon, then bump into a Japanese tourist and set a high price.

Gambling tricks

Three-card Monte, ‘Find The Queen’, the “Three-card Trick”, or “Follow The Lady”, is (except for the props) essentially the same as the probably centuries-older shell game or thimblerig. The trickster shows three playing cards to the audience, one of which is a queen (the “lady”), then places the cards face-down, shuffles them around and invites the audience to bet on which one is the queen. At first the audience is skeptical, so the shill places a bet and the scammer allows him to win. In one variation of the game, the shill will (apparently surreptitiously) peek at the lady, ensuring that the mark also sees the card. This is sometimes enough to entice the audience to place bets, but the trickster uses sleight of hand to ensure that they always lose, unless the conman decides to let them win, hoping to lure them into betting much more. The mark loses whenever the dealer chooses to make him lose. This con appears in the Eric Garcia novel Matchstick Men and is featured in the movie Edmond.

A variation on this scam exists in Barcelona, Spain, but with the addition of a pickpocket. The dealer and shill behave in an overtly obvious manner, attracting a larger audience. When the pickpocket succeeds in stealing from a member of the audience, he signals the dealer. The dealer then shouts the word “aqua”, and the three split up. The audience is left believing that “aqua” is a code word indicating the police are coming, and that the performance was a failed scam.

In the Football Picks Scam the scammer sends out tip sheet stating a game will go one way to 100 potential victims and the other way to another 100. The next week, the 100 or so who received the correct answer are divided into two groups and fed another pick. This is repeated until a small population have (apparently) received a series of supernaturally perfect picks, then the final pick is offered for sale. Despite being well-known (it was even described completely on an episode of The Simpsons and used by Derren Brown in “The System”), this scam is run almost continuously in different forms by different operators. The sports picks can also be replaced with securities, or any other random process, in an alternative form. This scam has also been called the inverted pyramid scheme, because of the steadily decreasing population of victims at each stage.

Visitors to Las Vegas or other gambling towns often encounter the Barred Winner scam, a form of advance fee fraud performed in person. The artist will approach his mark outside a casino with a stack or bag of high-value casino chips and say that he just won big, but the casino accused him of cheating and threw him out without letting him redeem the chips. The artist asks the mark to go in and cash the chips for him. The artist will often offer a percentage of the winnings to the mark for his trouble. But, when the mark agrees, the artist feigns suspicion and asks the mark to put up something of value “for insurance”. The mark agrees, hands over jewelry, a credit card or their wallet, then goes in to cash the chips. When the mark arrives at the cashier, they are informed the chips are fake. The artist, by this time, is long gone with the mark’s valuables.

False reward tricks

The glim-dropper requires several accomplices, one of whom must be a one-eyed man. One grifter goes into a store and pretends he has lost his glass eye. Everyone looks around, but the eye cannot be found. He declares that he will pay a thousand-dollar reward for the return of his eye, leaving contact information. The next day, an accomplice enters the store and pretends to find the eye. The storekeeper (the intended griftee), thinking of the reward, offers to take it and return it to its owner. The finder insists he will return it himself, and demands the owner’s address. Thinking he will lose all chance of the reward, the storekeeper offers a hundred dollars for the eye. The finder bargains him up to $250, and departs.…

The fiddle game uses the pigeon drop technique. A pair of con men work together, one going into an expensive restaurant in shabby clothes, eating, and claiming to have left his wallet at home, which is nearby. As collateral, the con man leaves his only worldly possession, the violin that provides his livelihood. After he leaves, the second con man swoops in, offers an outrageously large amount (for example $50,000) for such a rare instrument, then looks at his watch and runs off to an appointment, leaving his card for the mark to call him when the fiddle-owner returns. The mark’s greed comes into play when the “poor man” comes back, having gotten the money to pay for his meal and redeem his violin. The mark, thinking he has an offer on the table, then buys the violin from the fiddle player (who “reluctantly” sells it eventually for, say, $5,000). The result is the two conmen are $5,000 richer (less the cost of the violin), and the mark is left with a cheap instrument.

Other confidence tricks and techniques

The Landlord Scam advertises an apartment for rent at an attractive price. The con artist, usually someone who is house-sitting or has a short-term sublet at the unit, takes a deposit and first/last month’s rent from every person who views the suite. When move-in day arrives, the con artist is of course gone, and the apartment belongs to none of the angry people carrying boxes.

Change raising is a common short con and involves an offer to change an amount of money with someone, while at the same time taking change or bills back and forth to confuse the person as to how much money is actually being changed. The most common form, “the Short Count”, has been featured prominently in several movies about grifting, notably Nueve Reinas, The Grifters and Paper Moon. A con artist shopping at, say a gas station, is given 80 cents in change because he lacks two dimes to complete the sale (say the sale cost is $19.20 and the con man has a 20 dollar bill). He goes out to his car and returns a short time later, with 20 cents. He returns them, saying that he found the rest of the change to make a dollar, and asking for a bill so he will not have to carry coins. The confused store clerk agrees, exchanging a dollar for the 20 cents the conman returned. In essence, the mark makes change twice.

Beijing tea scam is a famous scam in and around Beijing. The artists (usually female and working in pairs) will approach tourists and try to make friends. After chatting, they will suggest a trip to see a tea ceremony, claiming that they have never been to one before. The tourist is never shown a menu, but assumes that this is how things are done in China. After the ceremony, the bill is presented to the tourist, charging upwards of $100 per head. The artists will then hand over their bills, and the tourists are obliged to follow suit.

All about freezing to death

Ice mask, C.T. Madigan / photograph by Frank Hurley

From Peter Stark’s “As Freezing Persons Recollect the Snow–First Chill–Then Stupor–Then the Letting Go” (Outside: January 1997):

There is no precise core temperature at which the human body perishes from cold. At Dachau’s cold-water immersion baths, Nazi doctors calculated death to arrive at around 77 degrees Fahrenheit. The lowest recorded core temperature in a surviving adult is 60.8 degrees. For a child it’s lower: In 1994, a two-year-old girl in Saskatchewan wandered out of her house into a minus-40 night. She was found near her doorstep the next morning, limbs frozen solid, her core temperature 57 degrees. She lived.

The cold remains a mystery, more prone to fell men than women, more lethal to the thin and well muscled than to those with avoirdupois, and least forgiving to the arrogant and the unaware.

Were you a Norwegian fisherman or Inuit hunter, both of whom frequently work gloveless in the cold, your chilled hands would open their surface capillaries periodically to allow surges of warm blood to pass into them and maintain their flexibility. This phenomenon, known as the hunter’s response, can elevate a 35-degree skin temperature to 50 degrees within seven or eight minutes.

Other human adaptations to the cold are more mysterious. Tibetan Buddhist monks can raise the skin temperature of their hands and feet by 15 degrees through meditation. Australian aborigines, who once slept on the ground, unclothed, on near-freezing nights, would slip into a light hypothermic state, suppressing shivering until the rising sun rewarmed them.

The exertion that warmed you on the way uphill now works against you: Your exercise-dilated capillaries carry the excess heat of your core to your skin, and your wet clothing dispels it rapidly into the night. The lack of insulating fat over your muscles allows the cold to creep that much closer to your warm blood.

Your temperature begins to plummet. Within 17 minutes it reaches the normal 98.6. Then it slips below.

At 97 degrees, hunched over in your slow search, the muscles along your neck and shoulders tighten in what’s known as pre-shivering muscle tone. Sensors have signaled the temperature control center in your hypothalamus, which in turn has ordered the constriction of the entire web of surface capillaries. Your hands and feet begin to ache with cold.

At 95, you’ve entered the zone of mild hypothermia. You’re now trembling violently as your body attains its maximum shivering response, an involuntary condition in which your muscles contract rapidly to generate additional body heat.

And after this long stop, the skiing itself has become more difficult. By the time you push off downhill, your muscles have cooled and tightened so dramatically that they no longer contract easily, and once contracted, they won’t relax. You’re locked into an ungainly, spread-armed, weak-kneed snowplow.

As you sink back into the snow, shaken, your heat begins to drain away at an alarming rate, your head alone accounting for 50 percent of the loss. The pain of the cold soon pierces your ears so sharply that you root about in the snow until you find your hat and mash it back onto your head.

But even that little activity has been exhausting. You know you should find your glove as well, and yet you’re becoming too weary to feel any urgency. You decide to have a short rest before going on.

An hour passes. at one point, a stray thought says you should start being scared, but fear is a concept that floats somewhere beyond your immediate reach, like that numb hand lying naked in the snow. You’ve slid into the temperature range at which cold renders the enzymes in your brain less efficient. With every one-degree drop in body temperature below 95, your cerebral metabolic rate falls off by 3 to 5 percent. When your core temperature reaches 93, amnesia nibbles at your consciousness.

In the minus-35-degree air, your core temperature falls about one degree every 30 to 40 minutes, your body heat leaching out into the soft, enveloping snow. Apathy at 91 degrees. Stupor at 90.

You’ve now crossed the boundary into profound hypothermia. By the time your core temperature has fallen to 88 degrees, your body has abandoned the urge to warm itself by shivering. Your blood is thickening like crankcase oil in a cold engine. Your oxygen consumption, a measure of your metabolic rate, has fallen by more than a quarter. Your kidneys, however, work overtime to process the fluid overload that occurred when the blood vessels in your extremities constricted and squeezed fluids toward your center. You feel a powerful urge to urinate, the only thing you feel at all.

By 87 degrees you’ve lost the ability to recognize a familiar face, should one suddenly appear from the woods.

At 86 degrees, your heart, its electrical impulses hampered by chilled nerve tissues, becomes arrhythmic. It now pumps less than two-thirds the normal amount of blood. The lack of oxygen and the slowing metabolism of your brain, meanwhile, begin to trigger visual and auditory hallucinations.

At 85 degrees, those freezing to death, in a strange, anguished paroxysm, often rip off their clothes. This phenomenon, known as paradoxical undressing, is common enough that urban hypothermia victims are sometimes initially diagnosed as victims of sexual assault. Though researchers are uncertain of the cause, the most logical explanation is that shortly before loss of consciousness, the constricted blood vessels near the body’s surface suddenly dilate and produce a sensation of extreme heat against the skin.

There’s an adage about hypothermia: “You aren’t dead until you’re warm and dead.”

At about 6:00 the next morning, his friends, having discovered the stalled Jeep, find him, still huddled inches from the buried log, his gloveless hand shoved into his armpit. The flesh of his limbs is waxy and stiff as old putty, his pulse nonexistent, his pupils unresponsive to light. Dead.

But those who understand cold know that even as it deadens, it offers perverse salvation. Heat is a presence: the rapid vibrating of molecules. Cold is an absence: the damping of the vibrations. At absolute zero, minus 459.67 degrees Fahrenheit, molecular motion ceases altogether. It is this slowing that converts gases to liquids, liquids to solids, and renders solids harder. It slows bacterial growth and chemical reactions. In the human body, cold shuts down metabolism. The lungs take in less oxygen, the heart pumps less blood. Under normal temperatures, this would produce brain damage. But the chilled brain, having slowed its own metabolism, needs far less oxygen-rich blood and can, under the right circumstances, survive intact.

Setting her ear to his chest, one of his rescuers listens intently. Seconds pass. Then, faintly, she hears a tiny sound–a single thump, so slight that it might be the sound of her own blood. She presses her ear harder to the cold flesh. Another faint thump, then another.

The slowing that accompanies freezing is, in its way, so beneficial that it is even induced at times. Cardiologists today often use deep chilling to slow a patient’s metabolism in preparation for heart or brain surgery. In this state of near suspension, the patient’s blood flows slowly, his heart rarely beats–or in the case of those on heart-lung machines, doesn’t beat at all; death seems near. But carefully monitored, a patient can remain in this cold stasis, undamaged, for hours.

In fact, many hypothermia victims die each year in the process of being rescued. In “rewarming shock,” the constricted capillaries reopen almost all at once, causing a sudden drop in blood pressure. The slightest movement can send a victim’s heart muscle into wild spasms of ventricular fibrillation. In 1980, 16 shipwrecked Danish fishermen were hauled to safety after an hour and a half in the frigid North Sea. They then walked across the deck of the rescue ship, stepped below for a hot drink, and dropped dead, all 16 of them.

The doctor rapidly issues orders to his staff: intravenous administration of warm saline, the bag first heated in the microwave to 110 degrees. Elevating the core temperature of an average-size male one degree requires adding about 60 kilocalories of heat. A kilocalorie is the amount of heat needed to raise the temperature of one liter of water one degree Celsius. Since a quart of hot soup at 140 degrees offers about 30 kilocalories, the patient curled on the table would need to consume 40 quarts of chicken broth to push his core temperature up to normal. Even the warm saline, infused directly into his blood, will add only 30 kilocalories.

Ideally, the doctor would have access to a cardiopulmonary bypass machine, with which he could pump out the victim’s blood, rewarm and oxygenate it, and pump it back in again, safely raising the core temperature as much as one degree every three minutes. But such machines are rarely available outside major urban hospitals.

You’d nod if you could. But you can’t move. All you can feel is throbbing discomfort everywhere. Glancing down to where the pain is most biting, you notice blisters filled with clear fluid dotting your fingers, once gloveless in the snow. During the long, cold hours the tissue froze and ice crystals formed in the tiny spaces between your cells, sucking water from them, blocking the blood supply. You stare at them absently.

“I think they’ll be fine,” a voice from overhead says. “The damage looks superficial. We expect that the blisters will break in a week or so, and the tissue should revive after that.”

If not, you know that your fingers will eventually turn black, the color of bloodless, dead tissue. And then they will be amputated.

You’ve seen that in the infinite reaches of the universe, heat is as glorious and ephemeral as the light of the stars. Heat exists only where matter exists, where particles can vibrate and jump. In the infinite winter of space, heat is tiny; it is the cold that is huge.

Outline for an Unpublished Linux Textbook

Back in 2004 or so, I was asked to write an outline for a college textbook that would be used in courses on Linux. I happily complied, producing the outline you can see on my website. The editor on the project loved the outline & showed it several professors to get their reactions, which were uniformly positive, with one prof reporting back that (& I’m paraphrasing here) “It was like this author read my mind, as this is exactly the book I’d like to use in my course!” Sadly, the book was never written, because the editor’s boss didn’t like the fact that I didn’t have a PhD in Computer Science. I thought that to be a silly reason then, & I think it’s a silly reason to reject the book now.

However, their loss is your gain. Here’s the outline for the book. Yes, it’s sadly outdated. Yes, it focuses quite a bit on SUSE, but that was what the publisher wanted. Yes, Linux has come a LONG way since I wrote this outline. But I still think it’s a damn good job, and you may find it interesting for historical reasons. So, enjoy!

Give CLEAR your info, watch CLEAR lose your info

From “Missing SFO Laptop With Sensitive Data Found” (CBS5: 5 August 2008):

The company that runs a fast-pass security prescreening program at San Francisco International Airport said Tuesday that it found a laptop containing the personal information of 33,000 people more than a week after it apparently went missing.

The Transportation Security Administration announced late Monday that it had suspended new enrollments to the program, known as Clear, after the unencrypted computer was reported stolen at SFO.

The laptop was found Tuesday morning in the same company office where it supposedly had gone missing on July 26, said spokeswoman Allison Beer.

“It was not in an obvious location,” said Beer, who said an investigation was under way to determine whether the computer was actually stolen or had just been misplaced.

The laptop contained personal information on applicants to the program, including names, address and birth dates, and in some cases driver’s license, passport or green card numbers, the company said.

The laptop did not contain Social Security numbers, credit card numbers or fingerprint or iris images used to verify identities at the checkpoints, Beer said.

In a statement, the company said the information on the laptop, which was originally reported stolen from its locked office, “is secured by two levels of password protection.” Beer called the fact that the personal information itself was not encrypted “a mistake” that the company would fix.

Gottman on relationships

From THE MATHEMATICS OF LOVE: A Talk with John Gottman (Edge: 14 April 2004):

So far, his surmise is that “respect and affection are essential to all relationships working and contempt destroys them. It may differ from culture to culture how to communicate respect, and how to communicate affection, and how not to do it, but I think we’ll find that those are universal things”.

Another puzzle I’m working on is just what happens when a baby enters a relationship. Our study shows that the majority (67%) of couples have a precipitous drop in relationship happiness in the first 3 years of their first baby’s life. That’s tragic in terms of the climate of inter-parental hostility and depression that the baby grows up in. That affective climate between parents is the real cradle that holds the baby. And for the majority of families that cradle is unsafe for babies.

So far I believe we’re going to find that respect and affection are essential to all relationships working and contempt destroys them. It may differ from culture to culture how to communicate respect, and how to communicate affection, and how not to do it, but I think we’ll find that those are universal things.

Bob Levenson and I were very surprised when, in 1983, we found that we could actually predict, with over 90 percent accuracy, what was going to happen to a relationship over a three-year period just by examining their physiology and behavior during a conflict discussion, and later just from an interview about how the couple viewed their past. 90% accuracy!

That was surprising to us. It seemed that people either started in a mean-spirited way, a critical way, started talking about a disagreement, started talking about a problem as just a symptom of their partner’s inadequate character, which made their partner defensive and escalated the conflict, and people started getting mean and insulting to one another. That predicted the relationship was going to fall apart. 96% of the time the way the conflict discussion started in the first 3 minutes determined how it would go for the rest of the discussion. And four years later it was like no time had passed, their interaction style was almost identical. Also 69% of the time they were talking about the same issues, which we realized then were “perpetual issues” that they would never solve. These were basic personality differences that never went away. She was more extroverted or she was more of an explorer or he was more punctual or frugal.

Some couples were caught by the web of these perpetual issues and made each other miserable, they were “grid locked” like bumper-to-bumper traffic with these issues, while other couples had similar issues but coped with them and had a “dialogue” that even contained laughter and affection. It seemed that relationships last to the extent that you select someone whose annoying personality traits don’t send you into emotional orbit. Once again conventional wisdom was wrong. The big issue wasn’t helping couples resolve their conflicts, but moving them from gridlock to dialogue. And the secret of how to do that turned out to be having each person talk about their dream within the conflict and bringing Viktor Frankl’s existential logotherapy into the marital boxing ring. Once people talked about what they wished for and hoped for in this gridlock conflict and the narrative of why this was so important to them, in 86% of the cases they would move from gridlock to dialogue. Again a new door opened. Not all marital conflicts are the same. You can’t teach people a set of skills and just apply them to every issue. Some issues are deeper, they have more meaning. And then it turned out that the very issues that cause the most pain and alienation can also be the greatest sources of intimacy and connection.

Another surprise: we followed couples for as long as 20 years, and we found that there was another kind of couple that didn’t really show up on the radar; they looked fine, they weren’t mean, they didn’t escalate the conflict — but about 16 to 22 years after the wedding they started divorcing. They were often the pillars of their community. They seemed very calm and in control of their lives, and then suddenly they break up. Everyone is shocked and horrified. But we could look back at our early tapes and see the warning signs we had never seen before. Those people were people who just didn’t have very much positive connection. There wasn’t very much affection — and also especially humor — between them.

…These sorts of emotionally disconnected relationships were another important dimension of failed relationships. We learned through them that the quality of the friendship and intimacy affects the nature of conflict in a very big way.

One of the major things we found is that honoring your partner’s dreams is absolutely critical. A lot of times people have incompatible dreams — or they don’t want to honor their partner’s dreams, or they don’t want to yield power, they don’t want to share power. So that explains a lot of times why they don’t really belong together.

Psycho-physiology is an important part of this research. It’s something that Bob Levenson brought to the search initially, and then I got trained in psycho-physiology as well. And the reason we’re interested in what was happening in the body is that there’s an intimate connection between what’s happening to the autonomic nervous system and what happening in the brain, and how well people can take in information — how well they can just process information — for example, just being able to listen to your partner — that is much harder when your heart rate is above the intrinsic rate of the heart, which is around a hundred to a hundred and five beats a minute for most people with a healthy heart.

At that point we know, from Loren Rowling’s work, that people start secreting adrenalin, and then they get into a state of diffuse physiological arousal (or DPA) , so their heart is beating faster, it’s contracting harder, the arteries start getting constricted, blood is drawn away from the periphery into the trunk, the blood supply shuts down to the gut and the kidney, and all kinds of other things are happening — people are sweating, and things are happening in the brain that create a tunnel vision, one in which they perceive everything as a threat and they react as if they have been put in great danger by this conversation.

Because men are different. Men have a lot of trouble when they reach a state of vigilance, when they think there’s real danger, they have a lot of trouble calming down. and there’s probably an evolutionary history to that. Because it functioned very well for our hominid ancestors, anthropologists think, for men to stay physiologically aroused and vigilant, in cooperative hunting and protecting the tribe, which was a role that males had very early in our evolutionary history. Whereas women had the opposite sort of role, in terms of survival of the species, those women reproduced more effectively who had the milk-let-down reflex, which only happens when oxytocin is secreted in the brain, it only happens when women — as any woman knows who’s been breast-feeding, you have to be able to calm down and relax. But oxytocin is also the hormone of affiliation. So women have developed this sort of social order, caring for one another, helping one another, and affiliating, that also allows them to really calm down and have the milk let-down reflex. And so — it’s one of nature’s jokes. Women can calm down, men can’t; they stay aroused and vigilant.

Physiology becomes really critical in this whole thing. A provocative finding from Alyson Shapiro’s recent dissertation is that if we take a look at how a couple argues when the woman is in the sixth month of pregnancy, we can predict over half the variation in the baby, the three-month-old baby’s vagal tone, which is the ability of the vagus nerve, the major nerve of the parasympathetic branch of the autonomic nervous system, which is responsible for establishing calm and focusing attention. That vagus nerve in the baby is eventually going to be working well if the parents, during pregnancy, are fighting with each other constructively. That takes us into fetal development, a whole new realm of inquiry.

You have to study gay and Lesbian couples who are committed to each other as well as heterosexual couples who are committed to each other, and try and match things as much as you can, like how long they’ve been together, and the quality of their relationship. And we’ve done that, and we find that there are two gender differences that really hold up.

One is that if a man presents an issue, to either a man he’s in love with or a woman he’s in love with, the man is angrier presenting the issue. And we find that when a woman receives an issue, either from a woman she loves or a man she loves, she is much more sad than a man would be receiving that same issue. It’s about anger and sadness. Why? Remember, Bowlby taught us that attachment and loss and grief are part of the same system. So women are finely tuned to attaching and connecting and to sadness and loss and grief, while men are attuned to defend, stay vigilant, attack, to anger. My friend Levenson did an acoustic startle study (that’s where you shoot of a blank pistol behind someone’s head when they least expect it). Men had a bigger heart rate reactivity and took longer to recover, which we would expect, but what even more interesting is that when you asked people what they were feeling, women were scared and men were angry.

So that’s probably why those two differences have held up. Physiologically people find over and over again in heterosexual relationships — and this hasn’t been studied yet in gay and Lesbian relationships — that men have a lower flash point for increasing heart-rate arousal, and it takes them longer to recover. And not only that, but when men are trying to recover, and calm down, they can’t do it very well because they keep naturally rehearsing thoughts of righteous indignation and feeling like an innocent victim. They maintain their own vigilance and arousal with these thoughts, mostly of getting even, whereas women really can distract themselves and calm down physiologically from being angered or being upset about something. If women could affiliate and secrete oxytocin when they felt afraid, they’s even calm down faster, probably.

The future of security

From Bruce Schneier’s “Security in Ten Years” (Crypto-Gram: 15 December 2007):

Bruce Schneier: … The nature of the attacks will be different: the targets, tactics and results. Security is both a trade-off and an arms race, a balance between attacker and defender, and changes in technology upset that balance. Technology might make one particular tactic more effective, or one particular security technology cheaper and more ubiquitous. Or a new emergent application might become a favored target.

By 2017, people and organizations won’t be buying computers and connectivity the way they are today. The world will be dominated by telcos, large ISPs and systems integration companies, and computing will look a lot like a utility. Companies will be selling services, not products: email services, application services, entertainment services. We’re starting to see this trend today, and it’s going to take off in the next 10 years. Where this affects security is that by 2017, people and organizations won’t have a lot of control over their security. Everything will be handled at the ISPs and in the backbone. The free-wheeling days of general-use PCs will be largely over. Think of the iPhone model: You get what Apple decides to give you, and if you try to hack your phone, they can disable it remotely. We techie geeks won’t like it, but it’s the future. The Internet is all about commerce, and commerce won’t survive any other way.

Marcus Ranum: … Another trend I see getting worse is government IT know-how. At the rate outsourcing has been brain-draining the federal workforce, by 2017 there won’t be a single government employee who knows how to do anything with a computer except run PowerPoint and Web surf. Joking aside, the result is that the government’s critical infrastructure will be almost entirely managed from the outside. The strategic implications of such a shift have scared me for a long time; it amounts to a loss of control over data, resources and communications.

Bruce Schneier: … I’m reminded of the post-9/11 anti-terrorist hysteria — we’ve confused security with control, and instead of building systems for real security, we’re building systems of control. Think of ID checks everywhere, the no-fly list, warrantless eavesdropping, broad surveillance, data mining, and all the systems to check up on scuba divers, private pilots, peace activists and other groups of people. These give us negligible security, but put a whole lot of control in the government’s hands.

That’s the problem with any system that relies on control: Once you figure out how to hack the control system, you’re pretty much golden. So instead of a zillion pesky worms, by 2017 we’re going to see fewer but worse super worms that sail past our defenses.

How it feels to drown, get decapitated, get electrocuted, and more

From Anna Gosline’s “Death special: How does it feel to die?” (New Scientist: 13 October 2007):

Death comes in many guises, but one way or another it is usually a lack of oxygen to the brain that delivers the coup de grâce. Whether as a result of a heart attack, drowning or suffocation, for example, people ultimately die because their neurons are deprived of oxygen, leading to cessation of electrical activity in the brain – the modern definition of biological death.

If the flow of freshly oxygenated blood to the brain is stopped, through whatever mechanism, people tend to have about 10 seconds before losing consciousness. They may take many more minutes to die, though, with the exact mode of death affecting the subtleties of the final experience.

Drowning

Typically, when a victim realises that they cannot keep their head above water they tend to panic, leading to the classic “surface struggle”. They gasp for air at the surface and hold their breath as they bob beneath, says Tipton. Struggling to breathe, they can’t call for help. Their bodies are upright, arms weakly grasping, as if trying to climb a non-existent ladder from the sea. Studies with New York lifeguards in the 1950s and 1960s found that this stage lasts just 20 to 60 seconds.

When victims eventually submerge, they hold their breath for as long as possible, typically 30 to 90 seconds. After that, they inhale some water, splutter, cough and inhale more. Water in the lungs blocks gas exchange in delicate tissues, while inhaling water also triggers the airway to seal shut – a reflex called a laryngospasm. “There is a feeling of tearing and a burning sensation in the chest as water goes down into the airway. Then that sort of slips into a feeling of calmness and tranquility,” says Tipton, describing reports from survivors.

That calmness represents the beginnings of the loss of consciousness from oxygen deprivation, which eventually results in the heart stopping and brain death.

Heart attack

The most common symptom is, of course, chest pain: a tightness, pressure or squeezing, often described as an “elephant on my chest”, which may be lasting or come and go. This is the heart muscle struggling and dying from oxygen deprivation. Pain can radiate to the jaw, throat, back, belly and arms. Other signs and symptoms include shortness of breath, nausea and cold sweats.

Most victims delay before seeking assistance, waiting an average of 2 to 6 hours. Women are the worst, probably because they are more likely to experience less well-known symptoms, such as breathlessness, back or jaw pain, or nausea, says JoAnn Manson, an epidemiologist at Harvard Medical School.

Even small heart attacks can play havoc with the electrical impulses that control heart muscle contraction, effectively stopping it. In about 10 seconds the person loses consciousness, and minutes later they are dead.

Bleeding to death

People can bleed to death in seconds if the aorta, the major blood vessel leading from the heart, is completely severed, for example, after a severe fall or car accident.

Death could creep up much more slowly if a smaller vein or artery is nicked – even taking hours. Such victims would experience several stages of haemorrhagic shock. The average adult has 5 litres of blood. Losses of around 750 millilitres generally cause few symptoms. Anyone losing 1.5 litres – either through an external wound or internal bleeding – feels weak, thirsty and anxious, and would be breathing fast. By 2 litres, people experience dizziness, confusion and then eventual unconsciousness.

Fire

Long the fate of witches and heretics, burning to death is torture. Hot smoke and flames singe eyebrows and hair and burn the throat and airways, making it hard to breathe. Burns inflict immediate and intense pain through stimulation of the nociceptors – the pain nerves in the skin. To make matters worse, burns also trigger a rapid inflammatory response, which boosts sensitivity to pain in the injured tissues and surrounding areas.

Most people who die in fires do not in fact die from burns. The most common cause of death is inhaling toxic gases – carbon monoxide, carbon dioxide and even hydrogen cyanide – together with the suffocating lack of oxygen. One study of fire deaths in Norway from 1996 found that almost 75 per cent of the 286 people autopsied had died from carbon monoxide poisoning.

Depending on the size of the fire and how close you are to it, concentrations of carbon monoxide could start to cause headache and drowsiness in minutes, eventually leading to unconsciousness. According to the US National Fire Protection Association, 40 per cent of the victims of fatal home fires are knocked out by fumes before they can even wake up.

Decaptitation

Beheading, if somewhat gruesome, can be one of the quickest and least painful ways to die – so long as the executioner is skilled, his blade sharp, and the condemned sits still.

Quick it may be, but consciousness is nevertheless believed to continue after the spinal chord is severed. A study in rats in 1991 found that it takes 2.7 seconds for the brain to consume the oxygen from the blood in the head; the equivalent figure for humans has been calculated at 7 seconds.

It took the axeman three attempts to sever the head of Mary Queen of Scots in 1587. He had to finish the job with a knife.

Decades earlier in 1541, Margaret Pole, the Countess of Salisbury, was executed at the Tower of London. She was dragged to the block, but refused to lay her head down. The inexperienced axe man made a gash in her shoulder rather than her neck. According to some reports, she leapt from the block and was chased by the executioner, who struck 11 times before she died.

Electrocution

In accidental electrocutions, usually involving low, household current, the most common cause of death is arrhythmia, stopping the heart dead. Unconsciousness ensues after the standard 10 seconds, says Richard Trohman, a cardiologist at Rush University in Chicago. One study of electrocution deaths in Montreal, Canada found that 92 per cent had probably died from arrhythmia.

Higher currents can produce nearly immediate unconsciousness.

Fall from a height

A high fall is certainly among the speediest ways to die: terminal velocity (no pun intended) is about 200 kilometres per hour, achieved from a height of about 145 metres or more. A study of deadly falls in Hamburg, Germany, found that 75 per cent of victims died in the first few seconds or minutes after landing.

The exact cause of death varies, depending on the landing surface and the person’s posture. People are especially unlikely to arrive at the hospital alive if they land on their head – more common for shorter (under 10 metres) and higher (over 25 metres) falls. A 1981 analysis of 100 suicidal jumps from the Golden Gate Bridge in San Francisco – height: 75 metres, velocity on impact with the water: 120 kilometres per hour – found numerous causes of instantaneous death including massive lung bruising, collapsed lungs, exploded hearts or damage to major blood vessels and lungs through broken ribs.

Survivors of great falls often report the sensation of time slowing down. The natural reaction is to struggle to maintain a feet-first landing, resulting in fractures to the leg bones, lower spinal column and life-threatening broken pelvises. The impact travelling up through the body can also burst the aorta and heart chambers. Yet this is probably still the safest way to land, despite the force being concentrated in a small area: the feet and legs form a “crumple zone” which provides some protection to the major internal organs.

Some experienced climbers or skydivers who have survived a fall report feeling focused, alert and driven to ensure they landed in the best way possible: relaxed, legs bent and, where possible, ready to roll.

Hanging

Suicides and old-fashioned “short drop” executions cause death by strangulation; the rope puts pressure on the windpipe and the arteries to the brain. This can cause unconsciousness in 10 seconds, but it takes longer if the noose is incorrectly sited. Witnesses of public hangings often reported victims “dancing” in pain at the end of the rope, struggling violently as they asphyxiated. Death only ensues after many minutes, as shown by the numerous people being resuscitated after being cut down – even after 15 minutes.

When public executions were outlawed in Britain in 1868, hangmen looked for a less performance-oriented approach. They eventually adopted the “long-drop” method, using a lengthier rope so the victim reached a speed that broke their necks. It had to be tailored to the victim’s weight, however, as too great a force could rip the head clean off, a professionally embarrassing outcome for the hangman.

Despite the public boasting of several prominent executioners in late 19th-century Britain, a 1992 analysis of the remains of 34 prisoners found that in only about half of cases was the cause of death wholly or partly due to spinal trauma. Just one-fifth showed the classic “hangman’s fracture” between the second and third cervical vertebrae. The others died in part from asphyxiation.

Lethal injection

Michael Spence, an anthropologist at the University of Western Ontario in London, Canada, has found similar results in US victims. He concluded, however, that even if asphyxiation played a role, the trauma of the drop would have rapidly rendered all of them unconscious. “What the hangmen were looking for was quick cessation of activity,” he says. “And they knew enough about their craft to ensure that happened. The thing they feared most was decapitation.”
Lethal injection

US-government approved, but is it really painless?

Lethal injection was designed in Oklahoma in 1977 as a humane alternative to the electric chair. The state medical examiner and chair of anaesthesiology settled on a series of three drug injections. First comes the anaesthetic thiopental to speed away any feelings of pain, followed by a paralytic agent called pancuronium to stop breathing. Finally potassium chloride is injected, which stops the heart almost instantly.

Each drug is supposed to be administered in a lethal dose, a redundancy to ensure speedy and humane death. However, eyewitnesses have reported inmates convulsing, heaving and attempting to sit up during the procedure, suggesting the cocktail is not always completely effective.

Explosive decompression

In real life there has been just one fatal space depressurisation accident. This occurred on the Russian Soyuz-11 mission in 1971, when a seal leaked upon re-entry into the Earth’s atmosphere; upon landing all three flight crew were found dead from asphyxiation.

Most of our knowledge of depressurisation comes from animal experiments and the experiences of pilots in accidents at very high altitudes. When the external air pressure suddenly drops, the air in the lungs expands, tearing the fragile gas exchange tissues. This is especially damaging if the victim neglects to exhale prior to decompression or tries to hold their breath. Oxygen begins to escape from the blood and lungs.

Experiments on dogs in the 1950s showed that 30 to 40 seconds after the pressure drops, their bodies began to swell as the water in tissues vaporised, though the tight seal of their skin prevented them from “bursting”. The heart rate rises initially, then plummets. Bubbles of water vapour form in the blood and travel through the circulatory system, obstructing blood flow. After about a minute, blood effectively stops circulating.

Human survivors of rapid decompression accidents include pilots whose planes lost pressure, or in one case a NASA technician who accidentally depressurised his flight suit inside a vacuum chamber. They often report an initial pain, like being hit in the chest, and may remember feeling air escape from their lungs and the inability to inhale. Time to the loss of consciousness was generally less than 15 seconds.

Hallucinating the presence of the dead

From Vaughan Bell’s “Ghost Stories: Visits from the Deceased” (Scientific American: 2 December 2008):

The dead stay with us, that much is clear. They remain in our hearts and minds, of course, but for many people they also linger in our senses—as sights, sounds, smells, touches or presences. Grief hallucinations are a normal reaction to bereavement but are rarely discussed, because people fear they might be considered insane or mentally destabilised by their loss. As a society we tend to associate hallucinations with things like drugs and mental illness, but we now know that hallucinations are common in sober healthy people and that they are more likely during times of stress.

Mourning seems to be a time when hallucinations are particularly common, to the point where feeling the presence of the deceased is the norm rather than the exception. One study, by the researcher Agneta Grimby at the University of Goteborg, found that over 80 percent of elderly people experience hallucinations associated with their dead partner one month after bereavement, as if their perception had yet to catch up with the knowledge of their beloved’s passing. As a marker of how vivid such visions can seem, almost a third of the people reported that they spoke in response to their experiences. In other words, these weren’t just peripheral illusions: they could evoke the very essence of the deceased.

Occasionally, these hallucinations are heart-rending. A 2002 case report by German researchers described how a middle aged woman, grieving her daughter’s death from a heroin overdose, regularly saw the young girl and sometimes heard her say “Mamma, Mamma!” and “It’s so cold.” Thankfully, these distressing experiences tend to be rare, and most people who experience hallucinations during bereavement find them comforting, as if they were re-connecting with something of the positive from the person’s life. Perhaps this reconnecting is reflected in the fact that the intensity of grief has been found to predict the number of pleasant hallucinations, as has the happiness of the marriage to the person who passed away.

There are hints that the type of grief hallucinations might also differ across cultures. Anthropologists have told us a great deal about how the ceremonies, beliefs and the social rituals of death differ greatly across the world, but we have few clues about how these different approaches affect how people experience the dead after they have gone.

Why American car companies are in trouble

From Paul Ingrassia’s “How Detroit Drove Into a Ditch” (The Wall Street Journal: 25 October 2008):

This situation doesn’t stem from the recent meltdown in banking and the markets. GM, Ford and Chrysler have been losing billions since 2005, when the U.S. economy was still healthy. The financial crisis does, however, greatly exacerbate Detroit’s woes. As car sales plunge — both in the U.S. and in Detroit’s once-booming overseas markets — it’s becoming nearly impossible for the companies to cut costs fast enough to keep pace with the evaporation of their revenue. All three companies, once the very symbol of American economic might, need new capital, but their options for raising it are limited.

In all this lies a tale of hubris, missed opportunities, disastrous decisions and flawed leadership of almost biblical proportions. In fact, for the last 30 years Detroit has gone astray, repented, gone astray and repented again in a cycle not unlike the Israelites in the Book of Exodus.

Detroit failed to grasp — or at least to address — the fundamental nature of its Japanese competition. Japan’s car companies, and more recently the Germans and Koreans, gained a competitive advantage largely by forging an alliance with American workers.

Detroit, meanwhile, has remained mired in mutual mistrust with the United Auto Workers union. While the suspicion has abated somewhat in recent years, it never has disappeared — which is why Detroit’s factories remain vastly more cumbersome to manage than the factories of foreign car companies in the U.S.

Two incidents in 1936 and 1937 formed this lasting labor-management divide: the sit-down strike at GM’s factories in Flint, Mich., and the Battle of the Overpass in Detroit, in which Ford goons beat up union organizers. But the United Auto Workers prevailed, and as the GM-Ford-Chrysler oligopoly emerged in the 1940s, the union gained a labor monopoly in American auto factories. As costs increased, the companies routinely passed them on to U.S. consumers, who had virtually no alternatives in buying cars.

Nissan, Toyota and other Japanese car companies soon started building factories in America, followed by German and Korean auto makers. There are now 16 foreign-owned assembly plants in the U.S., and many more that build engines, transmissions and other components.

Several years ago Ford even considered dropping cars altogether because they weren’t profitable, and focusing entirely on trucks. Then in 2005, Hurricane Katrina and growing oil demand from China and India sent gasoline prices soaring and SUV sales plunging. GM lost $10.6 billion that year. Ford topped that by losing $12.7 billion in 2006. Last summer Daimler gave up on Chrysler, selling it to private-equity powerhouse Cerberus for about one-fourth of what it had paid to buy Chrysler. Last fall the UAW approved significant wage and benefit concessions, but they won’t kick in until 2010. That might be too late. GM lost $15.5 billion in this year’s second quarter, Ford lost $8.7 billion, and further losses are coming. (Closely held Chrysler, of course, doesn’t report financial results.)

The growth in data & the problem of storage

From Technology Review‘s “The Fading Memory of the State“:

Tom Hawk, general manager for enterprise storage at IBM, says that in the next three years, humanity will generate more data–from websites to digital photos and video–than it generated in the previous 1,000 years. … In 1996, companies spent 11 percent of their IT budgets on storage, but that figure will likely double to 22 percent in 2007, according to International Technology Group of Los Altos, CA.

… the Pentagon generates tens of millions of images from personnel files each year; the Clinton White House generated 38 million e-mail messages (and the current Bush White House is expected to generate triple that number); and the 2000 census returns were converted into more than 600 million TIFF-format image files, some 40 terabytes of data. A single patent application can contain a million pages, plus complex files like 3-D models of proteins or CAD drawings of aircraft parts. All told, NARA expects to receive 347 petabytes … of electronic records by 2022.

Currently, the Archives holds only a trivial number of electronic records. Stored on steel racks in NARA’s [National Archives and Records Administration] 11-year-old facility in College Park, the digital collection adds up to just five terabytes. Most of it consists of magnetic tapes of varying ages, many of them holding a mere 200 megabytes apiece–about the size of 10 high-resolution digital photographs.
