The Revolution in Photography


When a set of online teasers for a new camera called the Lytro appeared earlier this year, you could have been forgiven for seeing the invention as just another gimmick. The camera’s attention-grabbing feature is a kind of after-the-fact autofocus: with a click, any blurry portion in a picture can be snapped into sharpness—another step in the march of idiot-proof photography.

In fact, such image correction is merely a side effect of what is genuinely different about the technology. The Lytro, scheduled to reach buyers early next year, creates a wholly new kind of visual object, one that both exemplifies and exploits the way images are consumed in the digital era.

The underlying technique is called “light-field photography.” A traditional camera, of course, captures light reflected off its subject through a lens and onto a flat surface. Proper focus is important to ensure that the image you get is the precise slice of visual reality you want. But “computational photography,” pioneered by Marc Levoy of Stanford University and others, takes a different approach, essentially using hundreds of cameras to capture all the visual information in a scene and processing the results into a many-layered digital object. One of Levoy’s former students, Ren Ng, added the twist that resulted in the Lytro: instead of using multiple cameras, he integrated hundreds of micro lenses into a single device.

The upshot is a photograph that’s less a slice of visual information than a cube, from which you can choose whichever layer would make the most pleasing two-dimensional image for printing and framing. But you can also leave the picture as it is—a three-dimensional capture suitable for digital display or distribution—and let others do the fiddling. Rather than a definitive, static image, a light-field visual object is intrinsically interactive.

In the pictorial examples the Lytro company has released online, this flexibility comes across as a fun novelty: you can focus on the Empire State Building in the distance, or the raindrop-splattered window in the foreground. But the implications are more profound. “It’s fair to say that this technology is a game changer,” says Richard Koci Hernandez, a photographer and assistant professor of new media at the University of California at Berkeley. The company gave Hernandez a Lytro prototype to beta test, and he argues that it represents as important a breakthrough as auto-focus itself, or even the great shift to digital photography.

Imagine, he suggests, a photojournalist covering a presidential speech whose audience includes a clutch of protesters. Using a traditional camera, he says, “I could easily set my controls so that what’s in focus is just the president, with the background blurred. Or I could do the opposite, and focus on the protesters.” A Lytro capture, by contrast, will include both focal points, and many others. Distribute that image, he continues, and “the viewer can choose—I don’t want to sound professorial—but can choose the truth.”

Battlefield Main Street

[ed. Lots of links in this article to support the author's thesis that police forces across the country are becoming more reactive and militarized.  This might have something to do with it: Pentagon's 1033 program gave away over $500 million of leftover military gear to law enforcement agencies in 2011.]

In February of last year, video surfaced of a marijuana raid in Columbia, Mo. During the raid on Jonathan Whitworth and his family, police took down the door with a battering ram, then within seconds shot and killed one of Whitworth's dogs and wounded the other. They didn't find enough pot in the house to charge Whitworth with even a misdemeanor. (He was, however, charged with misdemeanor possession of drug paraphernalia when police found a pipe.) The disturbing video went viral in May 2010, triggering outrage around the world. On Fox News, conservative columnist Charles Krauthammer and Bill O'Reilly cautioned not to judge the entire drug war by the video, which they characterized as an isolated incident.

In fact, very little about the raid that was isolated or unusual. For the most part, it was carried out the same way drug warrants are served some 150 times per day in the United States. The battering ram, the execution of Whitworth's dog, the fact that police weren't aware Whitworth's 7-year-old child was in the home before they riddled the place with bullets, the fact that they found only a small amount of pot, likely for personal use -- all are common in drug raids. The only thing unusual was that the raid was recorded by police, then released to the public after an open records request by the Columbia Daily Tribune. It was as if much of the country was seeing for the first time the violence with which the drug war is actually fought. And they didn't like what they saw.

That video came to mind with the outrage and public debate over the now-infamous pepper-spraying of Occupy protesters at the University of California-Davis protest earlier this month. The incident was just one of a number of high-profile uses of force amid crackdowns on Occupy protesters across the country, including one in Oakland in which the skull of Iraq War veteran Scott Olsen was fractured by a tear gas canister, and in New York, where NYPD Officer Anthony Bologna pepper-sprayed protesters who had been penned in by police fencing.

But America's police departments have been moving toward more aggressive, force-first, militaristic tactics and their accompanying mindset for 30 years. It's just that, with the exception of protests at the occasional free trade or World Bank summit, the tactics haven't generally been used on mostly white, mostly college-educated kids armed with cellphone cameras and a media platform.

Police militarization is now an ingrained part of American culture. SWAT teams are featured in countless cop reality shows, and wrong-door raids are the subject of "The Simpsons" bits and search engine commercials. Tough-on-crime sheriffs now sport tanks and hardware more equipped for battle in a war zone than policing city streets. Seemingly benign agencies such as state alcohol control boards and the federal Department of Education can now enforce laws and regulations not with fines and clipboards, but with volatile raids by paramilitary police teams.

Hubert Sumlin 1931–2011


Hubert Sumlin, the guitarist whose slashing solos and innovative ideas galvanized the blues of Howlin’ Wolf and inspired rock guitar players like Jimmy Page, Robbie Robertson and Eric Clapton, died on Sunday in Wayne, N.J. He was 80.

Mr. Sumlin began appearing on Howlin’ Wolf’s recordings in 1953, first as a rhythm guitarist and then, beginning in 1955, on lead guitar. Mr. Sumlin’s eerie guitar counterpart to Howlin’ Wolf’s unearthly moaning on the 1956 hit “Smokestack Lightnin’ ” has lately been featured in a television commercial for Viagra. He also played lead on “Back Door Man,” “Spoonful” and “The Red Rooster,” all written and arranged by the Chicago blues trailblazer Willie Dixon.

“Dixon’s often astute novelty lyrics and shrewd arrangements were topped off by Sumlin’s imaginative, angular, taut attack, frequent glisses, maniacally wide vibrato and percussive chords, all drawn with an exaggerated brush,” the producer Dick Shurman observed of Mr. Sumlin’s relentlessly inventive playing in his liner notes to a 1991 boxed set of Howlin’ Wolf’s work for Chess Records.

“Back Door Man,” “Spoonful” and “The Red Rooster” were later made even more famous in versions released, respectively, by the Doors, Cream and the Rolling Stones. All three originally appeared on Howlin’ Wolf’s 1962 LP “Howlin’ Wolf,” which the critic Greil Marcus called “the finest of all Chicago blues albums,” largely because of Mr. Sumlin’s contribution.

Though at times tempestuous, Mr. Sumlin’s partnership with Howlin’ Wolf lasted until the singer’s death in 1976. Mr. Sumlin’s intuitive, empathetic accompaniment typically spurred his mentor to unpredictable and frenzied heights.

An Evolution Toward a Programmable Universe


[ed. NY Times special on the Future of Computing.]

Over the next 10 years, the physical world will become ever more overlaid with devices for sending and receiving information.

Already billions of processors are embedded in our smartphones, cars, appliances and buildings and the environment. These sensors can send out streams of data about their surroundings, and more and more it is anonymously transmitted to remote data centers — the “clouds” of Google, Amazon, Microsoft, Yahoo and Apple.

From these vast clouds, the companies can power apps that are “spatially aware.” For instance, Google Maps now draws on data in the cloud to sample the location and movement of cellphones in cars, producing a real-time picture of traffic congestion.

Smart electric grids are measuring our homes’ use of power; active people are tracking their heart rates; and hundreds of millions of us are uploading geo-tagged data to Flickr, Yelp, Facebook and Google Plus. As we look 10 years ahead, the fastest supercomputer (the “exascale” machine) will be composed of one billion processors, and the clouds will most likely grow to this scale as well, creating a distributed planetary computer of enormous power.

Such computational power, co-located with the gigantic storage that holds the data from all the incoming data streams, will enable faster-than-real-time simulations of many aspects of our physical world. As Mike Liebhold and his colleagues at the Institute for the Future have discussed, computing will have evolved from merely sensing local information to analyzing it to being able to control it. In this evolution, the world gradually becomes programmable.

China’s Dam Frenzy

China’s frenzied dam-building hit a wall recently in Burma (Myanmar), where the government’s bold decision to halt a controversial Chinese-led dam project helped to ease the path to the first visit by a US secretary of state to that country in more than a half-century.

The now-stalled $3.6 billion Myitsone Dam, located at the headwaters of Burma’s largest river, the Irrawaddy, was designed to pump electricity exclusively into China’s power grid, despite the fact that Burma suffers daily power outages. The State-Owned Assets Supervision and Administration Commission of China’s State Council hailed Myitsone as a model overseas project serving Chinese interests. The Burmese decision thus shocked China’s government, which had begun treating Burma as a reliable client state (one where it still has significant interests, including the ongoing construction of a multibillion-dollar oil and natural-gas pipeline).

Despite that setback, China remains the world’s biggest dam builder at home and abroad. Indeed, no country in history has built more dams than China, which boasts more dams than the rest of the world combined.

Before the Communists came to power in 1949, China had only 22 dams of any significant size. Now the country has more than half of the world’s roughly 50,000 large dams, defined as having a height of at least 15 meters, or a storage capacity of more than three million cubic meters. Thus, China has completed, on average, at least one large dam per day since 1949. If dams of all sizes are counted, China’s total surpasses 85,000.
According to the United Nations Food and Agriculture Organization, China’s dams had the capacity to store 562.4 cubic kilometers of water in 2005, or 20% of the country’s total renewable water resources. Since then, China has built scores of new dams, including the world’s largest: the Three Gorges Dam on the Yangtze River.

Mind Tricks

[ed. Hat tip to Boing Boing for pointing out this Reddit stream on "mind tricks" for everyday life.  Here are a few examples:]

You know that awkward moment when you and a stranger are walking towards each other but need to get past each other and you get confused and end up doing a left to right dance? Not for me! When I walk through large crowds of people, to avoid walking into anyone, I simply stare at my destination. I look no one in the eyes. People actually will watch your eyes and they avoid the direction you are going. If I look into people's eyes as we are walking into each other, we are sure to collide. You have to let people know where you intend to go with your eyes. It always works for me, try it!

If you're trying to find something, try looking right to left as opposed to left to right. Your eyes tend to skim over things if you search in the direction you are used to reading in, so skim the opposite way. It takes me a bit more effort to do this, but I notice more details.

If you're in a crowded social group, restaurant, bar, party etc... and you want to know if someone is checking you out try this: Turn sideways from them (they will be either 90 degrees right or left of you), then very obviously, look at your watch (even if you don't wear one, lift your wrist) then point at your watch and nod thoughtfully. Over acting is perfectly acceptable. If they are keeping tabs on you, even peripherally, they will have a sudden urge to know the time and will either look at their own watch, cell phone, or casually look at the various obvious places where someone would put a clock.

The door-in-the-face technique. The general idea is that you ask someone for a huge favor which you're relatively confident they'll say no to. Then you ask them for a small favor. Subjects who initially refuse the huge favor have a much higher compliance rate on the small favor than if you just ask directly for the small favor or if you present both at once. If they end up saying yes to the huge favor, that's also good.

If you ask a question, and receive only a partial answer, respond with polite silence. Simply wait. A more complete answer will usually follow.

There's something in sales called the Sullivan Nod. Basically when you're asking someone something, nod up and down while you're asking. Their mirror neurons start firing and they begin nodding and agreeing with you subconsciously. 60% of the time it works every time.

Cat-Butt Coffee: A Critical Review


Kopi Luwak is the most expensive coffee in the world. At my local specialty coffee bean store, it sells for $420 per pound—or $10 for a 10 oz. brewed cup.

Kopi Luwak is very different from that cheap, gauche coffee you and I drink every day. This is because each hand-harvested bean of Kopi Luwak has been artisanally shat out of the digestive system of a small Indonesian pseudo-cat.

Yesterday, my husband and I split a cup of Kopi Luwak in an attempt to figure out whether having cat butt all over your coffee beans really did noticeably improve the flavor, or whether this was all just an elaborate practical joke on the part of Indonesian farmers.

The Asian Palm Civet is not really a cat, per se. It's a viverrid, a family of animals not found in North America. Viverrids belong to the same suborder as cats, so they are related. But, if you're not from Asian or African tropics, these animals will probably look a little weird to you. Imagine what might happen if the bastard love child of a ferret and a lemur had babies with your house cat. That's an Asian Palm Civet.

And Asian Palm Civets, as it turns out, really like to eat the fruits off of coffee plants. Although the civet can digest the fruit itself, the same can not be said for the bean at the center. Coffee beans pass through the civet whole. But they don't leave unchanged. Enzymes in the civet digestive tract break down proteins in the coffee beans. We know this because researchers at the University of Guelph actually did a detailed analysis in 2002, comparing Kopi Luwak and normal Columbian coffee beans. (You will be pleased to note that the same study confirmed that Kopi Luwak is safe to drink.)

Civets poop out coffee beans. This can happen on farms, or in the wild. Either way, once the pooping is done, somebody comes along to harvest the "processed" beans, cleans them, and roasts them. And then you have Kopi Luwak.

Here are the two things you need to know about the taste of Kopi Luwak:

• There is a difference in flavor. Kopi Luwak is noticeably not bitter. Swallow a sip, and it's like you just drank some water. There's no sting or heavy flavor left in the back of your throat. That makes sense. Proteins are part of what is responsible for the bitterness of coffee. Kopi Luwak beans have fewer whole proteins than normal beans. So they're less bitter, but still taste good. As my husband put it, "Everything that is wrong with cheap gas station coffee is right about this."

• That difference is totally not worth the price. Again, to quote my husband, "If I were a Russian oligarch or an investment banker or something, and $420 a pound represented a much smaller amount of my time worked, I'd probably drink this. As it is, not worth it."*

Cat-butt coffee: The coffee of the 1%?

Interestingly, Wikipedia tells me that Kopi Luwak originated during Dutch colonization of Indonesia, when Indonesians were banned from drinking any of the coffee they worked to grow and harvest. Instead, they gathered beans from civet poop and brewed that. And they talked about how great this cat-butt coffee was. Eventually, the Dutch colonists got curious, tried it for themselves, and then pretty much took it over. That's how Kopi Luwak became a luxury item. It's been expensive since the 19th century.

Of course, that history also lends a little more evidence to the theory that, somewhere, Indonesian farmers are having a good, long chuckle.

Monday Night Lights

How Jon Gruden became America’s football coach

Jon Gruden has one of the most recognizable faces in professional football, partly because he hasn’t worn a helmet since 1985, when he began his transformation from feckless college quarterback to triumphant professional coach. In 1998, he was named the head coach of the Oakland Raiders; in 2003, at thirty-nine, he won the Super Bowl with the Tampa Bay Buccaneers. Sports Illustrated chronicled his “spectacular” rise, and People anointed him one of the “beautiful people,” although his appearance was more impish than debonair—he was known as Chucky, because of his devilish squint, which made him resemble the psychotic doll from the horror movie “Child’s Play.”

In 2009, after a particularly disappointing season, the Buccaneers fired him, but, instead of moving on, he stayed put, and prospered. Gruden, who is now forty-eight, remained in Tampa, with his wife and three sons. He rented an office in a local strip mall, where he began presiding over irregular gatherings of a group that he calls the Fired Football Coaches Association. (He keeps boxes of F.F.C.A. visors and T-shirts in the bathroom, stacked in the shower stall.) Gruden’s office contains one of the country’s greatest collections of football videotapes, sorted according to a complicated taxonomy of his own devising. He says, “You want to talk about two-minute offense? Ball security? Nickel jam? Red-zone touchdown passes? Quarterback fundamentals? Read options? Three-down nickel blitzes? Checkdowns? Wildcats? I got it all down here.”  (...)

Gruden wakes up early, at three-seventeen (an arbitrary alarm-clock setting that stuck), and on a recent Thursday morning he arrived at the F.F.C.A. at around three-forty-five, pulling his white Mercedes into the empty lot. He wanted to learn everything he could about the New England Patriots and the Kansas City Chiefs, who were playing in the following Monday’s game. Gruden spent the morning examining “melts,” video compilations that allow him to view every play from just about every angle.

He is fit and reflexively physical, with a habit, common to coaches, of accentuating his statements with pokes, taps, and gentle shoves. But he has trained himself to sit still for hours, holding a professional-grade remote control called a Cowboy clicker, watching plays forward and backward, at full speed and in slow motion. He works in silence, except for his own occasional remarks. Every week, as he gets to know the two teams, he quickly comes to view their achievements and blunders as his own. “That wasn’t very good,” he murmured, after one uninspired Chiefs sequence. “That wasn’t our best effort. Wonder what happened.” Then he hit rewind and watched the play again.

There is no rational way to explain the amount of time that Gruden invests in each “Monday Night Football” broadcast: he spends days memorizing the names, numbers, and tendencies of all fifty-three players on both teams, even though little of this information makes it onto the broadcast. Once he has a sense of each team, he starts editing, creating a series of four-minute demonstration reels, known as “cutups,” to share with his producers and fellow-broadcasters, partly so they can create highlight clips for the show, and partly so that he can be sure they know what he’s talking about. When he is finished compiling a cutup, he sits with the Cowboy clicker in his left hand and a mouse in his right hand, so that he can run back and forth over the plays and draw emphatic arrows and circles, while he records an audio commentary track. These commentaries, for internal use only, are both loopier and more technical than what’s broadcast on “Monday Night Football.”

Turn On, Tune In and Get Better?

Hallucinogens and other street drugs are increasingly being studied for legitimate therapeutic uses, such as helping patients deal with post-traumatic stress disorder, addiction, chronic pain, depression and even terminal illness.

Janeen Delany describes herself as an "old hippie" who's smoked plenty of marijuana. But she never really dabbled in hallucinogens — until two years ago, at the age of 59.

A diagnosis of incurable leukemia had knocked the optimism out of the retired plant nurserywoman living in Phoenix. So she signed up for a clinical trial to test whether psilocybin — the active ingredient in "magic mushrooms" — could help with depression or anxiety following a grim diagnosis.

Delaney swallowed a blue capsule of psilocybin in a cozy office atJohns Hopkins University in Baltimore. She donned a blindfold, a cuff and a headset playing classical music. With two researchers at her side, she embarked on a six-hour journey into altered consciousness that she calls "the single most life-changing experience I've ever had."

What a long, strange trip it's been. In the 1960s and '70s, a rebellious generation embraced hallucinogens and a wide array of street drugs to "turn on, tune in and drop out." Almost half a century later, magic mushrooms, Ecstasy and ketamine are being studied for legitimate therapeutic uses. Scientists believe these agents have the potential to help patients with post-traumatic stress disorder, drug or alcohol addiction, unremitting pain or depression and the existential anxiety of terminal illness.

"Scientifically, these compounds are way too important not to study," said Johns Hopkins psychopharmacologist Roland Griffiths, who conducted the psilocybin trial.

In their next incarnation, these drugs may help the psychologically wounded tune in to their darkest feelings and memories and turn therapy sessions into heightened opportunities to learn and heal.

"We're trying to break a social mind-set saying these are strictly drugs of abuse," said Rick Doblin, a public policy expert who founded the Multidisciplinary Assn. for Psychedelic Studies in 1986 to encourage research on therapeutic uses for medical marijuana and hallucinogens. "It's not the drug but how the drug is used that matters."

Regulators and medical researchers remain wary. But among at least some experts at the National Institutes of Health and the Food and Drug Administration, the shift in attitude "has been dramatic," Doblin said.

Are Urban Bicyclists Elite Snobs?


In March, New Yorker columnist John Cassidy blogged about the city’s new bike lanes. He was annoyed that they made it harder for him to drive his Jaguar around Manhattan, and bemoaned the city’s bicyclists as a privileged, insular aristocracy, a “faddist minority intent on foisting its bipedalist views on a disinterested or actively reluctant populace.”

The Internet pounced. Cassidy’s blog posts usually get around a dozen comments. This one got 109, and not all were adoring fans. “The most tone-deaf, philistine commentary I’ve ever seen in these pages,” read one. “Honestly, if you love driving so much, please move to the Midwest,” another suggested. “Philistine and desultory drivel.”

Welcome to the new urban order: the Jag-driving New Yorker columnist is a philistine better suited to the suburbs of Wichita. Meanwhile, the city’s bicyclists are an entitled, imperial cabal cruising around on Trek Bellville three-speeds, an insidious locus of unchecked power and influence. How is this possible? As the blog Bike Snob NYC put it, someday in the future, “humanity will marvel that there was once an age in which a mode of transportation as inexpensive and accessible as the bicycle was considered ‘elitist.’”

Urban bicyclists have an image problem. They’ve become stereotyped as pretentious, aloof jackasses, and a lot of this has to do with the changes taking place in cities right now. During the last decade, dozens of urban cores were inundated by young, well-educated newcomers. Places like Philadelphia, Boston, Chicago and Washington added tens of thousands of these new residents. And one thing’s for sure: These kids really like bikes. An analysis by Atlantic Cities showed that bicycle ridership in these cities soared during this period. In some cases, it more than doubled.

Getting Far, Far Away From It All


On a Friday morning in October — Oct. 21, to be exact — Mark Trippetti, an advertising consultant from Williamsburg, Brooklyn, surrendered his laptop and iPhone to storage at a remote mountainside center in southern Colorado and prepared to drop out of human contact for a month.

The previous week he had begun the withdrawal process, leaving word with clients, cutting back his use of technology and giving up caffeine. Before checking out completely, he made one final call to his girlfriend, Jee Chang.

By careful design, Mr. Trippetti would not see or communicate with anyone until Nov. 20. At his spartan cabin he would rise each day at 3 a.m., sip from a thermos of tea that he had made the night before and move straight from his mattress to a cushion for three and a half hours of meditation and mantra recitation.

His days would be built around that, plus chores, repeated reading of some 200 pages of sadhana text and his own thoughts. Worldly necessities like food would be dropped periodically by the retreat center’s staff at the end of a path, 75 yards away, to avoid his glimpsing another human being. Bedtime was 10 p.m.

The silent, solo retreat, known as a lerung, is part of the practice of Tibetan Buddhism, a path that Mr. Trippetti, 54, a former advertising executive at J. Walter Thompson and Young & Rubicam, has been following for six years. He says that the effect on him has been profound.

“Going into a retreat is really about breaking down the constructs of ‘you,’ ” he said. “The whole idea is for you to take a very close look at the you you have become in your mind. The you you are in your real mind isn’t necessarily the real you.”

The idea of going for more than an hour or two without checking some sort of device for a text or e-mail, never mind face-to-face interaction, is unfathomable to many people in the professional world Mr. Trippetti inhabits. But there are overworked, overcommitted professionals in big cities like New York who periodically do just that.
