Marketers target Men

Marketers are also devoting much more effort to marketing to men—or, as Mr Lindstrom puts it, getting men to shop like women. In 1995 only 53% of American men admitted to shopping for themselves. That figure has risen to 75%. Many are buying traditionally “female” products; marketers created a $27 billion “male grooming” industry from nothing. They bombard men with images that were once reserved for women: think of Abercrombie & Fitch’s buff, topless hunks. (Not all hunks are appealing, however. The firm offered to pay a star of “Jersey Shore”, a crass reality show, not to wear its clothes.)

Bitcoin vs PayPal

Paypal and other online payment services are reliant on existing financial institutions to work. Your account is generally tied to a credit card or a checking/savings account—meaning that whenever you spend money, you're subject to the same restrictions and limitations you would have for using those. So, let's say you had tied your PayPal account to Visa with a $2,000 credit limit. Before making an online purchase in excess of that amount, you'd have to arrange for a credit extension or make changes to the source PayPal was drawing from. Using bitcoins, users can spend as much as they want—as long as they have a sufficient number of coins to cover the charge.

At the same time, because there's no way for a bitcoin account to be frozen, users can transfer funds wherever they like. For example, last year PayPal (as well as Visa and MasterCard blocked users from donating funds to WikiLeaks. Bitcoin donations, however, went through without a hiccup.

The Biggest Biometric Project in World

Massive Biometric Project Gives Millions of Indians an ID
;

The unprecedented scale of Aadhaar’s data will make managing it extraordinarily difficult. One of Nadhamuni’s most important tasks is de-duplication, ensuring that each record in the database is matched to one and only one person. That’s crucial to keep scammers from enrolling multiple times under different names to double-dip on their benefits. To guard against that, the agency needs to check all 10 fingers and both irises of each person against those of everyone else. In a few years, when the database contains 600 million people and is taking in 1 million more per day, Nadhamuni says, they’ll need to run about 14 billion matches per second. “That’s enormous,” he says.

Coping with that load takes more than just adding extra servers. Even Nadhamuni isn’t sure how big the ultimate server farm will be. He isn’t even totally sure how to work it yet. “Technology doesn’t scale that elegantly,” he says. “The problems you have at 100 million are different from problems you have at 500 million.” And Aadhaar won’t know what those problems are until they show up. As the system grows, different components slow down in different ways. There might be programming flaws that delay each request by an amount too tiny to notice when you’re running a small number of queries—but when you get into the millions, those tiny delays add up to a major issue. When the system was first activated, Nadhamuni says, he and his team were querying their database, created with the ubiquitous software MySQL, about 5,000 times a day and getting answers back in a fraction of a second. But when they leaped up to 20,000 queries, the lag time rose dramatically. The engineers eventually figured out that they needed to run more copies of MySQL in parallel; software, not hardware, was the bottleneck. “It’s like you’ve got a car with a Hyundai engine, and up to 30 miles per hour it does fine,” Nadhamuni says. “But when you go faster, the nuts and bolts fall off and you go, whoa, I need a Ferrari engine. But for us, it’s not like there are a dozen engines and we can just pick the fastest one. We are building these engines as we go along.”

Using both fingerprints and irises, of course, makes the task tremendously more complex. But irises are useful to identify the millions of adult Indians whose finger pads have been worn smooth by years of manual labor, and for children under 16, whose fingerprints are still developing. Identifying someone by their fingerprints works only about 95 percent of the time, says R. S. Sharma, the agency’s director general. Using prints plus irises boosts the rate to 99 percent.

That 1 percent error rate sounds pretty good until you consider that in India it means 12 million people could end up with faulty records. And given the fallibility of little-educated technicians in a poor country, the number could be even higher. A small MIT study of data entry on electronic forms by Indian health care workers found an error rate of 4.2 percent. In fact, at one point during my visit to Gagenahalli, Nadhamuni shows me the receipt given to a woman after her enrollment; I point out that it lists her as a man. A tad flustered, Nadhamuni assures me that there are procedures for people to get their records corrected. “Perfect solutions don’t exist,” Nilekani says, “but this is a substantial improvement over the way things are now.”

When two mathematicians, an anthropologist and a criminologist meet

In July the Santa Cruz Police Department began experimenting with an interesting bit of software developed by scientists at Santa Clara University. The researchers behind the software are like an intellectual “Oceans Eleven” team of specialists: two mathematicians, an anthropologist and a criminologist. They’ve combined their cerebral forces to come up with a mathematical model that takes crime data from the past to forecast crimes in the future. The basic math is similar to that used by seismologists to predict aftershocks following an earthquake (also a handy bit of software in southern California).

Large earthquakes are unpredictable, but the aftershocks that follow are not and their occurrence can be predicted with mathematical models. It occurred to Dr. George Mohler, one of the Santa Clara mathematicians, that criminal activity might not be random and that, similar to aftershocks, some crimes might be predicted by other crimes that precede them. The reasoning is based on the assumption that crimes are clustered – it’s what police call ‘hotspots.’ Burglaries will occur in the same area and at the same houses because the vulnerabilities of that area will be known to the burglars. Gang violence is also clustered. A gang shooting will often trigger retaliatory shootings.

Using the aftershocks-inspired algorithms Dr. Mohler and his team came up with a model, then sought to test it. In collaboration with the LAPD they plugged in data on 2,803 residential burglaries occurring within a block of the San Fernando valley 11 miles by 11 miles throughout 2004. For a given day the software calculated the top 5 percent of city blocks most likely to be burglarized. The results convinced the LAPD that, had they been using the program, they could have prevented a quarter of burglaries across the entire test region for that day.

The current, real world test of the software involves generating a map of the city areas most likely to be burglarized, the time of day they are most likely to get hit, and deploying personnel accordingly. The software is recalibrated every day when burglaries from the previous day are added to the dataset. They don’t actually expect to catch people in the act, but to deter more crimes with more effective patrolling. The test that is underway will be evaluated at six months, but already the data is encouraging. Zach Friend, crime analyst for Santa Cruz police, confirmed to the New York Times that the program led to five arrests in July. Even more impressive, compared to July 2010 burglaries, the number of July 2011 burglaries are down 27 percent. Whether or not that trend holds remains to be seen, but so far it appears that being in the wrong place at the right time works.

Honey, the Algorithm did it

And the thing is is that this isn't Google. This isn't information. These aren't financial stats; this is culture. And what you see here, or what you don't really see normally, is that these are the physics of culture. And if these algorithms, like the algorithms on Wall Street, just crashed one day and went awry, how would we know, what would it look like?

Digital Age Literature Analysis

Dan Cohen and Fred Gibbs, the two historians of science at George Mason University who have created the project, have so far charted how frequently more than two dozen words — among them “God,” “love,” “work,” “science” and “industrial” — appear in British book titles from the French Revolution in 1789 to the beginning of World War I in 1914. To Mr. Cohen, the sharply jagged lines that dance across his graphs can be used to test some of the most deeply entrenched beliefs about the Victorians, like their faith in progress and science: “We can finally and truly test these and other fundamental claims that have been at the heart of Victorian studies for generations.”

Mr. Cohen said that he and Mr. Gibbs hoped that their work could serve as a model for how scholars might use the shopping cart of new digital tools to challenge longstanding assumptions and interpretations across the humanities.

The Future of Printing- where Data is the Design Product

Freedom of Creation, based in Amsterdam, designs and prints exotic furniture and other fixtures for hotels and restaurants. It also makes iPhone cases for Apple, eye cream bottles for L’Oreal and jewelry and handbags for sale on its Web site.

Various designers have turned to the company for clothing that interlaces plastic to create form-hugging blouses, while others have requested spiky coverings for lights that look as if they could be the offspring of a sea urchin and a lamp shade.

“The aim was always to bring this to consumers instead of keeping it a secret at NASA and big manufacturers,” said Janne Kyttanen, 36, who founded Freedom of Creation about 10 years ago. “Everyone thought I was a lunatic when we started.”

His company can take risks with “out there” designs since it doesn’t need to print an object until it is ordered, Mr. Kyttanen said. Ikea can worry about mass appeal.

LGM, based in Minturn, Colo., uses a 3-D printing machine to create models of buildings and resorts for architectural firms.

It's easy to learn a language

MyLanguageExchange.com just maintains lists of people who know certain languages and want to learn others. Anyone can search the database, but only gold members, who pay $24 a year, can send e-mail easily to others.

Each person sets up a profile and includes a short description of age, location and what he or she would like to talk about. There is a big demand to practice English, and I found many possible pen pals.

Marie, 40, was born in Spain but lives in France near the Bordeaux region. She wants to improve her English and “perhaps find a job in sales export.” Serge, a Parisian who is retired, studies genealogy and wants to improve his English, Spanish and Swedish.

MyLanguageExchange.com claims it has more than 1.5 million members studying 115 languages.

I find the right partner through what are essentially classified ads. If I wanted to study Luxembourgish, the Germanic tongue of Luxembourg, there were 11 people looking to study English. There are 32 willing people who are fluent in Tswana, a Bantu language generally spoken around Southern Africa, mainly in Botswana. An e-mail or two is all it takes to find a study partner.

Maria, one of 113 people ready to help with Uyghur, which is spoken in western China, says she is also fluent in Mandarin but wants to practice Russian, Hindi and English. It is a big database.

The Facebook Effect

The Facebook Effect: The Inside Story of the Company that is Connecting the World. By David Kirkpatrick

In the early days Mr Zuckerberg comes across as a mixture of programming prodigy and business neophyte (his initial business cards bear the memorable phrase “I’m CEO…bitch!”). But his leadership instincts are commendably sharp. By surrounding himself with experienced advisers, he manages to steer Facebook clear of hurdles that threaten to derail its growth and soon finds himself the object of fawning attention from companies and venture capitalists drooling over the firm’s fast-growing franchise. The pressure on the fledgling entrepreneur is intense. In one scene Mr Zuckerberg retreats to the bathroom of a swank Silicon Valley restaurant and bursts into tears during a stressful negotiation over funding.

But behind the tears is toughness. Facebook’s boss turns down several Croesus-like offers to buy the company in spite of intense lobbying by fellow shareholders who think he should sell. And he pursues his vision of making the world a more open and connected place with single-minded determination. Some of the most interesting passages in “The Facebook Effect” describe how Mr Zuckerberg’s missionary zeal makes him ambivalent towards initiatives that would mint money for Facebook but fail to advance its agenda of “radical transparency”.

It is this zeal—and the company’s habit of suddenly revealing more of a user’s information in unexpected ways—that has repeatedly got it into hot water. Here Mr Kirkpatrick puts his finger on the contradiction between Mr Zuckerberg’s professed belief in the importance of protecting people’s privacy and his deep-seated conviction that people are rapidly losing interest in keeping their personal data hidden.

Freeman Dyson profile

Among Dyson’s gifts is interpretive clarity, a penetrating ability to grasp the method and significance of what many kinds of scientists do. His thoughts about how science works appear in a series of lucid, elegant books for nonspecialists that have made him a trusted arbiter of ideas ranging far beyond physics. Dyson has written more than a dozen books, including “Origins of Life” (1999), which synthesizes recent discoveries by biologists and geologists into an evaluation of the double-origin hypothesis, the possibility that life began twice; “Disturbing the Universe” (1979) tries among other things to reconcile science and humanity. “Weapons and Hope” (1984) is his meditation on the meaning and danger of nuclear weapons that won a National Book Critics Circle Award. Dyson’s books display such masterly control of complex matters that smart young people read him and want to be scientists; older citizens finish his books and feel smart.

Yet even while probing and sifting, Dyson is always whimsically gazing into the beyond. As a boy he sketched plans for English rocket ships that could explore the stars, and then, in midlife, he helped design an American spacecraft to be powered by exploding atomic bombs — a secret Air Force project known as Orion. Dyson remains an armchair astronaut who speculates with glee about the coming of cheap space travel, when families can leave an overcrowded earth to homestead on asteroids and comets, swooping around the universe via solar sail craft. Dyson is convinced that our current “age of computers” will soon give way to “the age of domesticated biotechnology.” Bio-tech, he writes in his book, “Infinite in All Directions” (1988), “offers us the chance to imitate nature’s speed and flexibility,” and he imagines the furniture and art that people will “grow” for themselves, the pet dinosaurs they will “grow” for their children, along with an idiosyncratic menagerie of genetically engineered cousins of the carbon-eating tree: termites to consume derelict automobiles, a potato capable of flourishing on the dry red surfaces of Mars, a collision-avoiding car.

These ideas attract derision similar to Dyson’s essays on climate change, but he is an undeterred octogenarian futurist. “I don’t think of myself predicting things,” he says. “I’m expressing possibilities. Things that could happen. To a large extent it’s a question of how badly people want them to. The purpose of thinking about the future is not to predict it but to raise people’s hopes.” Formed in a heretical and broad-thinking tradition of British public intellectuals, Dyson left behind a brooding England still stricken by two bloody world wars to become an optimistic American immigrant with tremendous faith in the creative imagination’s ability to invent technologies that would overcome any predicament. And according to the physicist and former Caltech president Marvin Goldberger, Dyson is himself the living embodiment of that kind of ingenuity. “You point Freeman at a problem and he’ll solve it,” Goldberger says. “He’s extraordinarily powerful.” Dyson seems to see the world as an interdisciplinary set of problems out there for him to evaluate. Climate change is the big scientific issue of our time, so naturally he finds it irresistible. But to Dyson this is really only one more charged conundrum attracting his interest just as nuclear weapons and rural poverty have. That is to say, he is a great problem-solver who is not convinced that climate change is a great problem.

Dyson is well aware that “most consider me wrong about global warming.” That educated Americans tend to agree with the conclusion about global warming reached earlier this month at the International Scientific Conference on Climate Change in Copenhagen (“inaction is inexcusable”) only increases Dyson’s resistance. Dyson may be an Obama-loving, Bush-loathing liberal who has spent his life opposing American wars and fighting for the protection of natural resources, but he brooks no ideology and has a withering aversion to scientific consensus. The Nobel physics laureate Steven Weinberg admires Dyson’s physics — he says he thinks the Nobel committee fleeced him by not awarding his work on quantum electrodynamics with the prize — but Weinberg parts ways with his sensibility: “I have the sense that when consensus is forming like ice hardening on a lake, Dyson will do his best to chip at the ice.”

Dyson says he doesn’t want his legacy to be defined by climate change, but his dissension from the orthodoxy of global warming is significant because of his stature and his devotion to the integrity of science. Dyson has said he believes that the truths of science are so profoundly concealed that the only thing we can really be sure of is that much of what we expect to happen won’t come to pass. In “Infinite in All Directions,” he writes that nature’s laws “make the universe as interesting as possible.” This also happens to be a fine description of Dyson’s own relationship to science. In the words of Avishai Margalit, a philosopher at the Institute for Advanced Study, “He’s a consistent reminder of another possibility.” When Dyson joins the public conversation about climate change by expressing concern about the “enormous gaps in our knowledge, the sparseness of our observations and the superficiality of our theories,” these reservations come from a place of experience. Whatever else he is, Dyson is the good scientist; he asks the hard questions. He could also be a lonely prophet. Or, as he acknowledges, he could be dead wrong.

The Economist who can predict the future

The New York University political science professor has developed a computerized game theory model that predicts the future of many business and political negotiations and also figures out ways to influence the outcome. Two independent evaluations, one by academics and one by the U.S. Central Intelligence Agency, have both shown that about 90 percent of his predictions have been accurate. Most recently, he has used his mathematical tools to offer approaches for handling the growing nuclear crisis with Iran...

Former CIA analyst Stanley Feder says that he has used Bueno de Mesquita's model well over a thousand times since the early 1980s to make predictions about specific policies. Like others, he has found it to be more than 90 percent accurate. In situations where predictions of the model differed from experts' predictions, the model always turned out to be correct.

"I'm always stunned that it works so well," Bueno de Mesquita says. "This 90 percent is not my assessment."

The main reason that the model generates more reliable predictions than experts do is that "the computer doesn't get bored, it doesn't get tired, and it doesn't forget," he says. In the analysis of nuclear technology development in Iran, for example, experts identified 80 relevant players. Because no individual can keep track of all the possible interactions between so many players, human analysts focus on five or six key players. The lesser players may not have a lot of power, Buena de Mesquita says, but they tend to be knowledgeable enough to influence how key decision-makers understand the issues. His model can keep track of those influences when a human can't.

"Given expert input of data for the variables for such a model, it would not surprise me in the least to see that it would perform well," says Branislav L. Slantchev, a political scientist and game theorist at the University of California at San Diego. Predictions based on game theory can fail in a context where people don't act rationally, but in Buena de Mesquita's work, Slantchev says, rational action mostly means that the players are promoting their own perceived interests as best they can, something humans tend to do.

The New Cold War: Putin's Russia and the Threat to the West
by Edward Lucas

A Book is not a book any more

Philip M. Parker seems to have licked that problem. Mr. Parker has generated more than 200,000 books, as an advanced search on Amazon.com under his publishing company shows, making him, in his own words, “the most published author in the history of the planet.” And he makes money doing it.

Among the books published under his name are “The Official Patient’s Sourcebook on Acne Rosacea” ($24.95 and 168 pages long); “Stickler Syndrome: A Bibliography and Dictionary for Physicians, Patients and Genome Researchers” ($28.95 for 126 pages); and “The 2007-2012 Outlook for Tufted Washable Scatter Rugs, Bathmats and Sets That Measure 6-Feet by 9-Feet or Smaller in India” ($495 for 144 pages).

But these are not conventional books, and it is perhaps more accurate to call Mr. Parker a compiler than an author. Mr. Parker, who is also the chaired professor of management science at Insead (a business school with campuses in Fontainebleau, France, and Singapore), has developed computer algorithms that collect publicly available information on a subject — broad or obscure — and, aided by his 60 to 70 computers and six or seven programmers, he turns the results into books in a range of genres, many of them in the range of 150 pages and printed only when a customer buys one.

If this sounds like cheating to the layman’s ear, it does not to Mr. Parker, who holds some provocative — and apparently profitable — ideas on what constitutes a book. While the most popular of his books may sell hundreds of copies, he said, many have sales in the dozens, often to medical libraries collecting nearly everything he produces. He has extended his technique to crossword puzzles, rudimentary poetry and even to scripts for animated game shows.

And he is laying the groundwork for romance novels generated by new algorithms. “I’ve already set it up,” he said. “There are only so many body parts.”
