Tim Wu writes for the New Yorker about how Netflix uses a ~70/30 combination of data and human judgment to determine their recommendations and what shows/movies to make.
Over the years, however, I’ve started to wonder whether Netflix’s big decisions are truly as data driven as they are purported to be. The company does have more audience data than nearly anyone else (with the possible exception of YouTube), so it has a reason to emphasize its comparative advantage. But, when I was reporting a story, a couple of years ago, about Netflix’s embrace of fandom over mass culture, I began to sense that their biggest bets always seemed ultimately driven by faith in a particular cult creator, like David Fincher (“House of Cards”), Jenji Leslie Kohan (“Orange is the New Black”), Ricky Gervais (“Derek”), John Fusco (“Marco Polo”), or Mitchell Hurwitz (“Arrested Development”). And, while Netflix does not release its viewership numbers, some of the company’s programming, like “Marco Polo,” hasn’t seemed to generate the same audience excitement as, say, “House of Cards.” In short, I do think that there is a sophisticated algorithm at work here — but I think his name is Ted Sarandos.
I presented Sarandos with this theory at a Sundance panel called “How I Learned to Stop Worrying and Trust the Algorithm,” moderated by Jason Hirschhorn, formerly of MySpace. Sarandos, very agreeably, wobbled a bit. “It is important to know which data to ignore,” he conceded, before saying, at the end, “In practice, its probably a seventy-thirty mix.” But which is the seventy and which is the thirty? “Seventy is the data, and thirty is judgment,” he told me later. Then he paused, and said, “But the thirty needs to be on top, if that makes sense.”
This reminds me of the situation in chess, where cyborg human/computer teams can beat computer- or human-only players in chess, although perhaps for not much longer.
Some of you will know that Average is Over contains an extensive discussion of “freestyle chess,” where humans can use any and all tools available — most of all computers and computer programs — to play the best chess game possible. The book also notes that “man plus computer” is a stronger player than “computer alone,” at least provided the human knows what he is doing. You will find a similar claim from Brynjolfsson and McAfee.
Computer chess expert Kenneth W. Regan has compiled extensive data on this question, and you will see that a striking percentage of the best or most accurate chess games of all time have been played by man-machine pairs. Ken’s explanations are a bit dense for those who don’t already know chess, computer chess, Freestyle and its lingo, but yes that is what he finds, click on the links in his link for confirmation. In this list for instance the Freestyle teams do very very well.
I wonder what the human/cyborg split is at Buzzfeed or Facebook? Or at food companies like McDonald’s or Kraft? Or at Goldman Sachs?
AHHHH! Lemur spider! Lemur spider!!!



From the newly launched site for the National Audubon Society, some gorgeous photos of owls from Brad Wilson.
It’s not easy to get owls to mug for the camera. Even in captivity the birds remain aloof, unruffled by the flash and unmoved by attempts to bribe them. Photographer Brad Wilson learned that lesson firsthand after trying to win over owls from the World Bird Sanctuary in St. Louis and The Wildlife Center near Espanola, New Mexico. He spent hours with each bird, trying to capture its direct gaze. “It’s hard to get animals to look at you like humans do,” he says. “That shot became my holy grail.”
I’ve featured Wilson’s animal photography on the site before. Tons more on his site.
The producers of A Most Violent Year, one of the year’s most acclaimed movies, are doing something interesting to promote their film. They’re running a blog that posts all sorts of media and information about NYC in 1981, the year the film is set. Today, they released a short documentary that features interviews with some people who were scraping together lives in NYC circa 1981. It’s worth watching:
Featuring Guardian Angels founder Curtis Sliwa, performance artist and former Warhol Factory fixture Penny Arcade, actress Johnnie Mae, Harlem street-style legend Dapper Dan, auto body shop owner Nick Rosello, and trucking union rep Wayne Walsh.
The trailer for A Most Violent Year is here…I’ve heard good things about this one and hope to catch it soon.

Clive Thompson writes about the newest innovation in junk mail marketing: handwriting robots. That’s right, robots can write letters in longhand with real ballpoint pens and you can’t really tell unless you know what to look for. Here’s a demonstration:
But it turns out that marketers are working diligently to develop forms of mass-generated mail that appear to have been patiently and lovingly hand-written by actual humans. They’re using handwriting robots that wield real pens on paper. These machines cost up to five figures, but produce letters that seem far more “human”. (You can see one of the robots in action in the video adjacent.) This type of robot is likely what penned the address on the junk-mail envelope that fooled me. I saw ink on paper, subconsciously intuited that it had come from a human (because hey, no laser-printing!) and opened it.
Handwriting, it seems, is the next Turing Test.
There is also a company that provided handwritten letters for sale professionals and I don’t know if that or the robot letters are more unusual.

I’ve caught a couple of episodes of CNN’s Anthony Bourdain: Parts Unknown and I’ve been impressed with the show so far. In it, chef/author Anthony Bourdain travels to places off the beaten path and explores the local culture. But it’s not just about food and culture as with his previous shows. In Parts Unknown, Bourdain also delves into local politics and social issues. In Iran, he spoke with journalists about their tenuous relationship with the government (and two of the journalists he spoke with were subsequently arrested). Episodes in the Congo, Myanmar, and Libya are produced with a focus on their oppressive governments, past and present. Even in the Massachusetts episode, he talks about his former heroin addiction and the current addiction of poor whites in the US. Many of the places he visits, we only hear about the leadership and bad things that happen on the news, but Bourdain meets with the locals and finds more similarities amongst cultures than differences. I’d never considered going to visit someplace like Iran, but Parts Unknown has me considering it…what a great people.

In their latest full episode, Radiolab examines the concept of worth, particularly when dealing with things that are more or less priceless (like human life and nature).
This episode, we make three earnest, possibly foolhardy, attempts to put a price on the priceless. We figure out the dollar value for an accidental death, another day of life, and the work of bats and bees as we try to keep our careful calculations from falling apart in the face of the realities of life, and love, and loss.
I have always really liked Radiolab, but it seems like the show has shifted into a different gear with this episode. The subject seemed a bit meatier than their usual stuff, the reporting was close to the story, and the presentation was more straightforward, with fewer of the audio experiments that some found grating. I spent some time driving last weekend and I listened to this episode of Radiolab, an episode of 99% Invisible, and an episode of This American Life, and it occurred to me that as 99% Invisible has been pushing quite effectively into Radiolab’s territory, Radiolab is having to up their game in response, more toward the This American Life end of the spectrum. Well, whatever it is, it’s great seeing these three radio shows (and dozens of others) push each other to excellence.
Being an avid eater and cooker of steak,1 a passage at the end of Tom Junod’s profile of Wylie Dufresne / obit of WD-50 caught my eye:
“That’s why I’m really proud of what we did here,” he said over his cup of sake. “I’m proud of the big things, but I’m also proud of the little things we routinely did well. Do you know what made me most proud in the meal I served you? The Wagyu beef. It was perfectly cooked.”
“The advantage of sous vide,” someone said.
“But it wasn’t sous vide!” Dufresne said. “That’s the thing. It was cooked in a pan. And it had no gray on it! Do you know how hard that is? Do you know how much work that takes? Turning the beef every seven or eight seconds … And so that question you asked me before, about food and music — that’s my answer: a perfect piece of Wagyu beef cooked in a pan that comes out without any gray on it. It might not be ‘When the Levee Breaks,’ but it’s definitely ‘Achilles Last Stand.’”
I couldn’t recall hearing about this fast flipping technique from the many pieces Kenji Lopez-Alt has published about how to and how not to cook steak, so I pinged him on Twitter. He responded with Flip Your Steaks Multiple Times For Better Results.
Let’s start with the premise. Anybody who’s ever grilled in their backyard with an overbearing uncle can tell you that if there’s one rule about steaks that gets bandied about more than others, it’s to not play with your meat once it’s placed on the grill. That is, once steak hits heat, you should at most flip it just once, perhaps rotating it 90 degrees on each side in order to get yourself some nice cross-hatched grill marks.
The idea sort of makes sense at first glance: flipping it only once will give your steak plenty of chance to brown and char properly on each side. But the reality is that flipping a steak repeatedly during cooking — as often as every 30 seconds or so — will produce a crust that is just as good (provided you start with meat with a good, dry surface, as you always should), give you a more evenly cooked interior, and cook in about 30% less time to boot!
It works for burgers too. Thanks, Kenji!
Although honestly, I eat and cook steak a lot less than I used to. Burgers too. A belly full of steak just doesn’t feel that good anymore, gastronomically, gastrointestinally, or environmentally. I’m trying to eat more vegetables and especially seafood. Actually, I’m not really trying…it’s just been working out that way. I still really like steak, but it’s almost become a special occasion food for me, which is probably the way it should from a sustainability standpoint. ↩

Related to my post last November about how the biodiversity of Yosemite Valley was mismanaged, author Michael Crichton shared a story at a 2005 talk about how the National Park Service has grossly mismanaged nature at Yellowstone National Park, resulting in less biodiversity, the disappearance of many natural species from the park, and catastrophic fires. Since this anecdote was part of a longer talk, I’ll quote the whole thing from the transcript.
Long recognized as a scene of great natural beauty, in 1872, Ulysses Grant set aside Yellowstone as the first formal nature preserve in the world. More than two million acres, larger than Delaware and Rhode Island combined. John Muir was very pleased when he visited in 1885, noting that under the care of the Department of the Interior, Yellowstone was protected from, quote, “the blind, ruthless destruction that is going on in adjoining regions.”
Theodore Roosevelt was also pleased in 1903, when as President, he went to Yellowstone for a dedication ceremony. Here he is. This was his third visit. Roosevelt saw a thousand antelope, plentiful cougar, mountain sheep, deer, coyote and many thousands of elk. He wrote at that time, “Our people should see to it that this rich heritage is preserved for their children and their children’s children forever, with its majestic beauty all unmarred.”
But in fact, Yellowstone was not preserved. On the contrary, it was altered beyond repair in a matter of years. By 1934, the Park Service acknowledged that whitetail deer, cougar, lynx, wolf, and possibly wolverine and fisher are gone from the Yellowstone.
What they didn’t say was that the Park Service was solely responsible for the disappearances. Park rangers had been shooting the animals for decades, even though that was illegal since the Lacey Act of 1894. But they thought they knew best. They thought their environmental concerns trumped any mere law.
What actually happened at Yellowstone is a cascade of ego and error, but to understand it, we have to go back to the 1890s. Back then, it was believed that elk were becoming extinct, so these animals were fed and encouraged. Over the next few years, the number of elk in the park exploded. Here you can see them feeding them hand to hand.
Roosevelt had seen a few thousand animals on his visit, and he’d noticed that the elk were more numerous than in his previous visit. Nine years later, in 1912, there were 30,000 elk in Yellowstone. By 1914, there were 35,000.
Things were going very well. Rainbow trout had also been introduced, and although they crowded out the native cutthroats, nobody really worried. Fishing was great. Bears were increasing in numbers, and moose and bison as well.
By 1915, Roosevelt realized the elk had become a problem, and he urged scientific management, which meant culling. His advice was ignored. Instead, the Park Service did everything they could to increase the number of elk. The results were predictable. Antelope and deer began to decline. Overgrazing changed the flora. Aspen and willows were being eaten at a furious rate and did not regenerate. Large animals and small began to disappear from the park.
In an effort to stem the loss, the park rangers began to kill predators, which they did without public knowledge. They eliminated the wolf and the cougar, and they were well on their way to getting rid of the coyote. Then a national scandal broke out. New studies showed that it wasn’t predators that were killing the other animals. It was overgrazing from too many elk. The management policy of killing predators therefore had only made things worse.
Actually, the elk had so decimated the aspen that now, where formerly they were plentiful, now they’re quite rare. Without the aspen, the beaver, which use these trees to make dams, began to disappear from the park. Beaver were essential to the water management of Yellowstone, and without dams, the meadows dried hard in summer and still more animals vanished.
The situation worsened further. It became increasingly inconvenient that all the predators had been killed off by 1930, so in the 1960s, there was a sigh of relief when new sightings by rangers suggested that wolves were returning. Of course, there were rumors all during that time, persistent rumors that the rangers were trucking them in. But in any case, the wolves vanished soon afterward. They needed to eat beaver and other small rodents, and the beaver had gone.
Pretty soon, the Park Service initiated a PR campaign to prove that excessive elk were not responsible for the problems in the park, even though they were. The campaign went on for about a decade, during which time the bighorn sheep virtually disappeared.
Now, we’re in the 1970s, and bears were recognized as a growing problem. They used to be considered fun-loving creatures, and their close association with human beings was encouraged in the park. Here’re people coming to watch bear feedings. There’s a show at a certain hour of the day. And here’s one of my favorites. Setting the table for bears at Lake Camp in Yellowstone Park. You see they’re very well behaved.
But that didn’t actually continue-the good behavior, I mean. There were more bears, and certainly there were many more lawyers, and thus the much-increased threat of litigation, so the rangers moved the grizzlies out. The grizzlies promptly became endangered. Their formerly growing numbers shrank. The Park Service refused to let scientists study them, but once they were declared endangered, the scientists could go back in again.
And by now, we’re about ready to reap the rewards of our 40-year policy of fire suppression, Smokey the Bear and all that. The Indians used to burn forests regularly, and lightning causes natural fires every year. But when these are suppressed, branches fall from the trees to the ground and accumulate over the years to make a dense groundcover such that when there’s a fire, it is a very low, very hot fire that sterilizes the soil. In 1988, Yellowstone burned, and all 1.2 million acres were scorched, and 800,000 acres, one third of the park, burned.
Then having killed the wolves, having tried to sneak them back in, they officially brought the wolves back. And now the local ranchers screamed. The newer reports suggested the wolves seemed to be eating enough of the elk that slowly, the ecology of the park was being restored. Or so it is claimed. It’s been claimed before. And on and on.
The Park Service’s bungling efforts at conservation were covered by Alston Chase in his 1987 book, Playing God in Yellowstone. (via @jhreha)
Update: As Crichton notes above, wolves were reintroduced into Yellowstone in 1995 and their presence started what’s called a trophic cascade. From Wikipedia:
Trophic cascades occur when predators in a food web suppress the abundance or alter traits (e.g., behavior) of their prey, thereby releasing the next lower trophic level from predation (or herbivory if the intermediate trophic level is a herbivore). For example, if the abundance of large piscivorous fish is increased in a lake, the abundance of their prey, zooplanktivorous fish, should decrease, large zooplankton abundance should increase, and phytoplankton biomass should decrease. This theory has stimulated new research in many areas of ecology. Trophic cascades may also be important for understanding the effects of removing top predators from food webs, as humans have done in many places through hunting and fishing activities.
In a TED talk, George Monbiot explains the surprising effects the wolves had on Yellowstone…they even changed the courses of the rivers flowing through the park.
Fascinating. A sort of trickle down ecology. (via @gasperak and several others)

This will really appeal to a certain type of nerd: the complete archives of Popular Electronics magazine in PDF format. Popular Electronics was the most popular magazine about electronics for hobbyists and was published from 1954 to 1982. If you’re interested in this, the rest of the American Radio History site is amazing as well.

Using ice-penetrating radar and ice cores, NASA has been able to map the layers in the Greenland ice sheet.
This new map allows scientists to determine the age of large swaths of Greenland’s ice, extending ice core data for a better picture of the ice sheet’s history. “This new, huge data volume records how the ice sheet evolved and how it’s flowing today,” said Joe MacGregor, a glaciologist at The University of Texas at Austin’s Institute for Geophysics and the study’s lead author.
Greenland’s ice sheet is the second largest mass of ice on Earth, containing enough water to raise ocean levels by about 20 feet. The ice sheet has been losing mass over the past two decades and warming temperatures will mean more losses for Greenland. Scientists are studying ice from different climate periods in the past to better understand how the ice sheet might respond in the future.
One way of studying this distant past is with ice cores. These cylinders of ice drilled from the ice sheet hold evidence of past snow accumulation and temperature and contain impurities like dust and volcanic ash that were carried by snow that accumulated and compacted over hundreds of thousands of years. These layers are visible in ice cores and can be detected with ice-penetrating radar.
Ice-penetrating radar works by sending radar signals into the ice and recording the strength and return time of reflected signals. From those signals, scientists can detect the ice surface, sub-ice bedrock and layers within the ice.
New techniques used in this study allowed scientists to efficiently pick out these layers in radar data. Prior studies had mapped internal layers, but not at the scale made possible by these newer, faster methods. Another major factor in this study was the amount of Greenland IceBridge has measured.
It’s amazing that the detectors and data analysis are sensitive enough to pick out different layers in the ice just from radar. (via @ptak)

Removal of items from US National Parks is illegal (or at least highly frowned upon). In the case of the Petrified Forest National Park in Arizona, the removal of petrified wood has come to be seen by some as unlucky. Bad Luck, Hot Rocks is a book and web site containing “conscience letters” from those who are returning stolen rocks to the park.

In the more than one hundred years since its establishment in 1906, however, some visitors have still been unable to resist the urge to remove wood from the park. Some of these same visitors eventually return their ill gotten souvenirs by mail, accompanied by ‘conscience letters.’ The content of each letter varies, but writers often include stories of misfortune, attributed directly to their stolen petrified wood. Car troubles. Cats with cancer. Deaths of family members. For many, their hope is that by returning these rocks, good fortune will return to their lives. Other common themes include expressions of remorse, requests for forgiveness, and warnings to future visitors.

All day on Saturday, Amazon will be streaming their acclaimed series Transparent for free (US-only probs) in celebration of the show’s wins at the Golden Globes (best TV series and best actor for Jeffrey Tambor). Here’s the press release.
“We’re incredibly proud of everyone involved in the making of Transparent-the team took a risk and it paid off,” said Jeff Bezos, founder and CEO of Amazon.com. “Big kudos and congrats to Jill, Jeffrey, and all the cast and crew.”
Written, directed and executive produced by Emmy-nominee and 2013 Sundance Best Director winner Jill Soloway, Transparent is a 10-episode, half-hour novelistic series that explores family, identity, sex, and love.
Amazon is also offering a Saturday-only discount on 1-yr Amazon Prime subscriptions…$72 instead of the usual $99. I loved Transparent…if you’re not doing anything for 5 hours on Saturday, I recommend hopping on this.
