Gadgetwise Blog: How to Beat Some Facebook Scammers

You’ve probably seen those wildly popular Facebook postings that entice you to share something — like a photo of a bear sneaking up on a man — with the instructions, “Press Like and type the number 1 and see what happens.” These posts often list hundreds of thousands of responses.

If you’ve tried it, here’s what you saw happen: nothing. Behind the scenes something is happening, though. With each click, a scammer gets a little closer to cashing in.

The most thorough explanation I’ve seen of how this deception works comes from Daylan Pearce, whose job title is Search Lead at Next Digital, described as Australia’s largest independent digital agency, in Melbourne.

Somewhat simplified, here’s how it works. There is a thriving business in selling Facebook pages. The idea is that a page builds an audience, then essentially sells that audience to someone else. It’s a practice Facebook opposes, but has limited control over.

If a company can buy that audience, its “edge rank” will increase. Edge rank — a term people like Mr. Pearce use, but which Facebook doesn’t officially acknowledge — measures how often someone’s posts show up in other people’s news feeds. “So,” Mr. Pearce said, “a page that has 50,000 likes will have greater exposure on people’s news feeds than a page with only 10,000.”

Edge rank is based on several factors, chief among them affinity, weight and decay, Mr. Pearce said. Affinity is largely based on the number of likes. Weight is based on what accompanies those likes. “A ‘like’ isn’t worth as much as a comment and a comment isn’t worth as much as a ‘share,’” he said.

Decay relates to the age of the post. More views, likes and shares over more time increases edge rank.

Facebook did not quarrel with the basics of Mr. Pearce’s explanation, but said it’s more complicated.

These scam posts are designed to do three things. Get you to like, comment and share the post. It’s a recipe to make it go viral, which takes care of decay.

To hook you, the posts make an intriguing promise, or ask you to support a worthy cause – “like this and share it if you know of someone who has suffered from cancer.”

While you can’t stop people from such postings, you can keep them off your page and reduce the potential profit. You lower their edge rank when you report or at least hide the post.

To do that, hold your cursor over the post and an arrow should appear in the upper right corner. Click it and a drop-down menu offers you the option of hiding or reporting the post.

The more often you report or hide these kinds of posts, the less often they will show up in your news feed.

Bits Blog: One on One: Sugata Mitra, 2013 TED Prize Winner

Are teachers keeping students from learning in the digital age? Sugata Mitra, a professor of educational technology at Newcastle University, believes so. Dr. Mitra is best known for an experiment in which he carved a hole from his research center in Delhi into an adjacent slum, placing a freely accessible computer there for children to use.

The children quickly taught themselves basic computer skills. The “hole in the wall” experiment, as it is known, led Dr. Mitra to develop the idea of learning environments in which teachers would merely be supervisors as children taught themselves by working together at computer terminals. On Tuesday Dr. Mitra was given the 2013 TED Prize, which grants him $1 million to build a learning laboratory based on this principle.

Q.

What did you learn from the original “hole in the wall” experiment?

A.

The first thing to point out is that it was done 14 years ago, at a time when few children in India had access to computers. I noticed the rich parents saying that their sons and daughters must be gifted, because they were so good with computers. And since we know that gifted kids are not born only to rich parents, why would there not be similar children in the slums? I was curious to see what would happen if I gave an Internet-connected computer to the kind of kids who never had one.

We noticed that they learned how to surf within hours. It was a bit of a surprise. Long story short, they would teach themselves whatever they had to to use the computer, such was the attraction of the machine.

Q.

What does this mean for education?

A.

In those days, the main question was what does it mean for training, because back then people were trained to use computers. So I said it looks like we don’t have to do that.

But I got curious about the fact that the children were teaching themselves a smattering of English. So I started doing a whole range of experiments, and I found that if you left them alone, working in groups, they could learn almost anything once they’ve gotten used to the fact that you can research on the Internet. This was done between 2000 and 2006.

I came to England in 2006, and the schools said, why aren’t you doing it here? So I did, and I realized that what I’ve got has nothing to do with poor children. It probably is just a new way in which children learn in this new environment. It needs two things. First, broadband. That’s fine, everybody loves that. The second thing is, it needs the teacher to stand back.

At first I thought that the children were learning in spite of the teacher not interfering. But I changed my opinion, and realized this was happening because the teacher was not interfering. At that point, I didn’t become entirely popular with teachers. But I explained to them that the job has changed. You ask the right kind of question, then you stand back and let the learning happen.

Q.

Do schools need to be radically changed to implement this, or is this a technique that fits into the current structure of schools?

A.

At the moment I pitch it as a technique that you can bring into your schools. But that’s not the real story, which is that the current schooling system is a leftover from the Victorian age of empire. In that world, there were no computers, no telegraphs and data was carried around on ships. This meant that the pillars of education were reading, writing and arithmetic. That age is gone. The system was wonderfully engineered, but we don’t need it anymore; we need something else. But you can’t just say that without saying how you do it.

What I’m doing is I’m putting my foot in the door by saying here’s a new way. Try it. If you’re happy with it, then I’ll say let’s look at the curriculum top to bottom. If we can convert the curriculum into big questions, if we can turn assessment into peer assessment, then neurophysiology tells us that learning gets enhanced. Finally, if you add admiration — what I call the grandmother’s method, where you stand behind and encourage them. Put all of this together and you get a new way to do schooling.

Q.

So it seems that you’re saying we don’t need teachers at all.

A.

We need teachers to do different things. The teacher has to ask the question, and tell the children what they have learned. She comes in at the two ends, a cap at the end and a starter at the beginning.

Teachers are not supposed to be repositories of information which they dish out. That is from an age when there were no other repositories of information, other than books or teachers, neither of which were portable. A lot of my big task is retraining these teachers. Now they have to watch as children learn.

Q.

Is there a problem with this in that it will serve the good students well, but leave those who need more coaching behind?

A.

Well, yes, to some extent. But there are some interesting things about children working in groups if those groups are self-made. Once you let children do that, the system has a self-correcting ability. Having said that, will there be good students and bad students? Of course.

Q.

Does this work for all levels of instruction?

A.

It doesn’t work the same way with adolescents, and definitely not with adults. With 8- to 12-year-olds, that’s the age where big questions turn them on.

Q.

What are your specific plans with the prize?

A.

In order to see if this sort of self-organized learning environment is suitable I need to have one in which I have some control over and can do measurements with. So I want to build one of these learning spaces somewhere.

It will be totally automatic, completely controlled from the cloud. There will be a supervisor, but that person is not going to be a computer expert or a teacher in anything. She — and it will probably be a she — will be there only for health and safety requirements.

The rest of the school, if we call it a school, is a facility that I can hand over to a mediator from the cloud. She logs in from her home, wherever her home is, and she’s able to control everything inside, the lights, the air-conditioning, you name it. Then there are four mediators who Skype in and use the pedagogical method. That’s going to take a lot of work.

The second bit is that schools all over the world have been using this method. We need to do a massive multiplication, and TED is going to help me do that. I am going to try to put that into homes; get your children and their friends together. Then, every time they do it, I’ll ask them to collect data and send it to a Web site. If I succeed, in two years I’ll have massive data from all over the world. By that time I’ll be done building the facility and I’ll be ready to build a new model.

Q.

Where do you think this school will be?

A.

I’d like to do it in India, because I’d know how to get it done. There will be less of a learning curve, I know who the contractors are, and I know how not to get cheated. So I’d like to do it there, but it’s not set in stone.

Bits Blog: Yahoo Issues a Statement on Work-at-Home Ban

In a front-page article in The New York Times on Tuesday morning, Catherine Rampell and I wrote about Yahoo’s new policy banning employees from working remotely. The company declined to comment for that article, but on Tuesday afternoon, it issued a statement about the ban against work-at-home arrangements.

“This isn’t a broad industry view on working from home,” the statement said. “This is about what is right for Yahoo right now.”

A company spokeswoman declined to elaborate on the statement, saying, “We don’t discuss internal matters.”

But based on information from several Yahoo employees, what that statement means is that Marissa Mayer, Yahoo’s new chief executive, is in crisis mode, and she believes the policy is necessary to get Yahoo back into shape.

The employees spoke anonymously because they are not allowed to discuss internal matters.

The company also seems to be trying to distance itself from the broader national debate over workplace flexibility, and from criticism that the new policy is disruptive for employees who have family responsibilities outside work.

The work ethic at Yahoo among some workers has deteriorated over time, the Yahoo employees said, and requiring people to show up is a way to keep an eye on them and re-energize the troops. If some of the least productive workers leave as a result, the thinking goes, all the better.

Some employees have abused the former policy permitting work at home to the point of founding start-ups while being on salary at Yahoo, said the Yahoo employees and others who have worked at the company.

Several business analysts said that if work-at-home arrangements don’t work, it is generally a management problem.

Yahoo’s culture and employee morale have dissolved as it has fallen behind hotter tech companies. And, business analysts say, those are two things that are difficult to repair without having employees present in the same place.

Still, Ms. Mayer has said many times that one of her top priorities for the company is to recruit the most talented engineers and other employees. Even if requiring people to show up is the only way to repair Yahoo’s culture, it could result in losing valuable employees.

And even if Yahoo’s broader work-at-home policy needed revision, the internal memo announcing the new policy struck some as tone-deaf by implying that employees should avoid staying at home even once in a while when there are extenuating circumstances.

“For the rest of us who occasionally have to stay home for the cable guy, please use your best judgment in the spirit of collaboration,” it said.

Bits Blog: Visa Teams Up With Samsung on Mobile Payments

The idea of paying for things with a phone is still foreign to most people, but now Visa and Samsung Electronics are working together to make mobile payments easier.

The companies on Monday said that many new Samsung phones would incorporate Visa’s payments software, called payWave. The software will come preloaded on all Samsung phones that have near-field communications technology, which allows users to tap their phones against a payment terminal to exchange information. Samsung’s popular Galaxy smartphones include near-field capabilities. Teri Daley, a Samsung spokeswoman, said Samsung’s next Galaxy smartphone, the Galaxy S IV, would be introduced March 14.

With this technology in place, the Visa payments app could potentially replace a customer’s Visa card. Outside companies, like retailers, could also choose to build the payment system into their apps.

In the past year several companies have announced different approaches to mobile payments, but the technology has not caught on with American consumers. Analysts say that is in part due to the fact that businesses have not proved that paying with a wallet is more convenient than using cash or a credit card. But it is also because the tech companies, banks and carriers are competing to have their own system gain dominance, rather than working together.

For example, after Square formed a partnership with Starbucks to accept mobile payments, other retailers like 7-Eleven, Best Buy and Wal-Mart formed an alliance to make their own mobile payments network. AT&T, Verizon Wireless and T-Mobile USA have formed their own mobile payments network called ISIS, while Sprint offers its own wallet system.

“Which is going to be the winner or loser?” said Eden Zoller, an analyst at Ovum, a research firm. “It’s not clear at the moment. It’s quite confusing that there’s Isis, PayPal, PayPal mobile app, Square and others. Which ones should users adopt?”

A partnership between such major companies has the potential to break this pattern — or just to add to the complexity of an already fractured market. Visa executives say there needs to be tighter collaboration between companies providing mobile payments, and the mobile wallet is still three to five years away from mainstream adoption.

But Jim McCarthy, Visa’s global head of product, said in an interview that working with Samsung, one of the world’s largest phone makers, was a big step to helping mobile payments gain traction, given Samsung’s reach and the fact that consumers will not have to choose which payments app to download.

Disruptions: Disruptions: Google Flu Trends Shows Problems of Big Data Without Context

Several years ago, Google, aware of how many of us were sneezing and coughing, created a fancy equation on its Web site to figure out just how many people had influenza. The math works like this: people’s location + flu-related search queries on Google + some really smart algorithms = the number of people with the flu in the United States.

So how did the algorithms fare this wretched winter? According to Google Flu Trends, at the flu season’s peak in mid-January, nearly 11 percent of the United States population had influenza.

Yikes! Take vitamins. Don’t leave the house. Wash your hands. Wash them again!

But wait. According to an article in the science journal Nature, Google’s disease-hunting algorithms were wrong: their results were double the actual estimates by the Centers for Disease Control and Prevention, which put the coughing and sniffling peak at 6 percent of the population.

Kelly Mason, a public affairs spokeswoman for Google, said the company’s Flu Trends site was meant to be only one source in addition to the C.D.C. and other flu surveillance methods. “We review and potentially update our model each season,” she said.

Scientists have a theory about what went wrong, as well.

“Several researchers suggest that the problems may be due to widespread media coverage of this year’s severe U.S. flu season,” Declan Butler wrote in Nature. Then add social media, which helped news of the flu spread quicker than the virus itself.

In other words, Google’s algorithm was looking only at the numbers, not at the context of the search results.

In today’s digitally connected world, data is everywhere: in our phones, search queries, friendships, dating profiles, cars, food, reading habits. Almost everything we touch is part of a larger data set. But the people and companies that interpret the data may fail to apply background and outside conditions to the numbers they capture.

“Data inherently has all of the foibles of being human,” said Mark Hansen, director of the David and Helen Gurley Brown Institute for Media Innovation at Columbia University. “Data is not a magic force in society; it’s an extension of us.”

Society has encountered similar situations for centuries. In the 1600s, Dr. Hansen said, an early census was recorded in England as the Great Plague of London killed tens of thousands of Britons. To calculate the spread of the disease, officials started recording every christening and death in the city. And although this helped quantify the mortality rate, it also created other problems. There was now an astounding collection of statistical information for scientists to review and understand, but it took time to develop systems that could accurately assess the information.

Now, as we enter a world of big data, we have to learn how to apply context to these numbers.

Dr. Hansen said the problem of data without context could be summed up in a quote from the playwright Eugène Ionesco: “Of course, not everything is unsayable in words, only the living truth.”

I experienced this firsthand in the spring of 2010, when I was an adjunct professor at New York University teaching graduate students in the Interactive Telecommunications Program.

I created a class called “Telling Stories With Data, Sensors and Humans,” with the goal of determining whether sensors and data could become reporters and collect information. Students built little electronic contraptions with $30 computers called Arduinos, and attached several sensors, including ones that could detect light, noise and movement.

We wondered if we could use these sensors to determine whether students used the elevators more than the stairs, and whether that changed throughout the day. (Esoteric, sure, but a perfect example of a computer sitting there taking notes, rather than a human.)

We set up the sensors in some elevators and stairwells at N.Y.U. and waited. To our delighted surprise, the data we collected told a story, and it seemed that our experiment had worked.

As I left campus that evening, one of the N.Y.U. security guards who had seen students setting up the computers in the elevators asked how our experiment had gone. I explained that we had found that students seemed to use the elevators in the morning, perhaps because they were tired from staying up late, and switch to the stairs at night, when they became energized.

“Oh, no, they don’t,” the security guard told me, laughing as he assured me that lazy college students used the elevators whenever possible. “One of the elevators broke down a few evenings last week, so they had no choice but to use the stairs.”

Bits: Online Gambling Heats Up

The two big casino states, Nevada and New Jersey, are racing into online gambling as a way of protecting their turf. They will in essence become laboratories for what is and is not feasible in Internet wagering.

Nevada legislators, who previously authorized online poker, hurriedly passed a new bill this week that allows the state to enter into deals with other states to essentially pool their gambling populations. “This is the day we usher Nevada into the next frontier of gaming,” Brian Sandoval, Nevada’s governor, said on Thursday as he signed the bill.

In the year since online poker became a theoretical possibility in Nevada, no company has yet offered it. One problem: It’s too small a market, especially in a state where it is not exactly hard to gamble the old-fashioned way — by plunking your body down in a casino or, for that matter, just about anywhere else.

“We don’t have a universe of players,” Pete Ernaut, a Nevada political consultant, told The Las Vegas Review-Journal. “So for us, what we get to offer to a state like California or Texas is that we have the most mature regulatory infrastructure. We have the most mature financial, auditing and collection capabilities, much greater than some of those states, and they have the players.”

Meanwhile, New Jersey is also barreling ahead. Chris Christie, the governor, is likely to sign a revised bill permitting a variety of online gambling as soon as next week. All online ventures will be under the tight control of the Atlantic City casinos. Delaware, the smallest of the three states that are moving ahead with online gambling, also has ambitious plans.

In a harbinger of the new age, gamblers at the Borgata casino in Atlantic City will, as USA Today put it, “be able to lose their shirts without wearing one.” Gamblers staying in one of the casino’s 2,000 rooms can now place their bets right there without venturing onto the casino floor. From there it is only a small step to just staying home and gambling from the hammock.

Internet companies that make online games are watching all this with considerable interest. “Is 2013 going to be a game-changer?” asked Paul Thelen of Big Fish Studios, which began offering a gambling app in Britain last fall. “No. But in 2014, it starts getting interesting.”

In a Slight Shift, North Korea Widens Internet Access, but Just for Visitors





HONG KONG — North Korea will finally allow Internet searches on mobile devices. But if you’re a North Korean, you’re out of luck — only foreigners will get this privilege.




Cracking the door open slightly to wider Internet use, the government will allow a company called Koryolink to give foreigners access to 3G mobile Internet service by next Friday, according to The Associated Press, which has a bureau in the North.


The North Korean police state is famously cloistered, a means for the government to keep news of the world from its impoverished people. Only the most elite North Koreans have been allowed access to the Internet, and even they are watched. And although many North Koreans are allowed to have cellphones, sanctioned phones cannot call outside the country.


Foreigners were only recently allowed to use cellphones in the country. Previously, most had to surrender their phones with customs agents.


But it is unlikely that the small opening will compromise the North’s tight control of its people; the relatively few foreigners who travel to North Korea — a group that includes tourists and occasional journalists — are assigned government minders.


The decision, announced Friday, to allow foreigners Internet access comes a month after Google’s chairman, Eric E. Schmidt, visited Pyongyang, the North’s capital. While there he prodded officials on allowing Internet access, noting how easy it would be to set up through the expanding 3G network of Koryolink, a joint venture of North Korean and Egyptian telecommunications corporations. Presumably, Mr. Schmidt’s appeal was directed at giving North Koreans such capability.


“As the world becomes increasingly connected, their decision to be virtually isolated is very much going to affect their physical world, their economic growth and so forth,” Mr. Schmidt told reporters following his visit. “We made that alternative very, very clear.”


North Koreans will get some benefit from the 3G service, as they will be allowed to text and make video calls, The Associated Press said. They can also view newspaper reports — but the news service mentioned only one source: Rodong Sinmun, the North’s main Communist Party newspaper.

DealBook: In Dell’s Waning Cash Flows, Signs of Concern

The proposed Dell buyout may be motivated more by fear than greed.

Dell’s founder, Michael S. Dell, and the investment firm Silver Lake are offering to take the company private in a $24.4 billion deal. One interpretation of the offer is that savvy investors, using cheap loans, see a nice opportunity to unlock the value from a company that has fallen out of favor with stock investors. The fact that large shareholders are opposed to the deal, thinking it is priced too low, supports the idea that Dell is a diamond in the rough.

But there is an opposite interpretation: The buyout is a last-ditch effort to revive the company. To some, taking Dell private is what’s necessary to implement the sort of bold measures that could prevent the steady decline of a company that has been left behind in many of its markets. And like many acts of desperation, the risks are high that going private will fail.

This viewpoint starts with Dell’s cash flows. How much actual money a company makes each quarter is always an important metric. It’s especially critical at firms that go private in leveraged buyout deals. Once private, Dell would have a lot more debt – and it would need divert more cash to service it.

Going private may allow the company to slash costs, which preserves cash. But management may also feel liberated to spend more on initiatives it feels enthusiastic about, which would use up cash initially. In a botched buyout, management’s plans fail to produce results and a dangerous cash crunch occurs.

And there are some signs that Dell’s cash flows are weakening going into the deal.

The cash flow metric that matters is called free cash flow, which takes the money generated by Dell’s operations and then subtracts what the company spends on capital expenditures. Through the end of its latest fiscal year, which ended in February, Dell’s free cash flows were $2.77 billion. That is well below the $4.85 billion reported in the prior fiscal year. And the recent cash flows may have gotten a boost from financial moves that might be hard to repeat. In the most recent quarter, Dell generated a lot of cash from taking longer to pay its suppliers.

It’s easy to paint a grim picture from these numbers. A privately held Dell might have an extra $700 million to $1 billion of extra interest a year, which could in theory take annual free cash flows below $2 billion. That provides little margin for safety if Dell’s operations run into serious trouble, even if the company does decide to dip into its large pool of overseas cash.

But there are some reasons to believe this analysis is overly pessimistic.

First, the cash flow numbers probably don’t fully factor in how much cash can be generated by Dell’s recent acquisitions. Just as a couple of items helped bolster cash flows in recent quarters, others used up a lot cash, and may not do so in the future. For instance, Dell had a $450 million cash drain in the last fiscal year just from the “deferred income taxes” line. That could be the result of a one-off action rather than a recurring trend.

With all its acquisitions contributing, optimists might contend that Dell can produce $3.5 billion of free cash flow a year. If investors paid seven times that, the company would be valued at the $24 billion, which is where it is valued today on the stock market. Other shareholders think Dell is worth a lot more than $24 billion, and has the cash flows to justify it.

But right now, Dell’s cash flows are weakening. And if they continue to wane, Mr. Dell may soon have a tough job ahead of him. He may already know that — looking at those cash flows.

Tool Kit: Some Premium Headphones Amplify Celebrities Over Sound





If you are planning a $200 splurge on premium headphones — as millions of people are this year — who will give you the most for your money? Maybe a rapper like Dr. Dre, 50 Cent, Nick Cannon or Ludacris?




Or will you get better sound with headphones branded by rockers like Motörhead or inspired by the reggae artist Bob Marley?


Maybe headphones associated with the sports stars Tim Tebow and Michael Phelps or the reality television star Nicole Polizzi, better known as Snooki, produce even better sound?


This is how headphones are marketed these days — affinity headphones, if you will. The sequins, rhinestones, feathers and faux leopard print on Ms. Polizzi’s $60 headphones attract buyers as much as their sound quality does. Headphones are in high demand. The Consumer Electronics Association estimates 79 million were sold last year, and it predicts 10 percent more than that will be sold this year. But the category of headphones costing more than $100 is growing even faster — 64 percent, according to market analysts at the NPD Group.


That is wonderful news for retailers who feel their profit margins squeezed on laptops, televisions and most other electronic products. “Retailers can make more on a high-end pair of headphones than they can make selling a smartphone in many instances,” said Ross Rubin of Reticle Research, a consumer electronics research firm.


Knowing what’s behind the marketing can help a consumer avoid the hype when choosing a product. Headphone designers estimate the cost of making a “fashion headset” selling for $200 is as low as $14. “I would have guessed $20 to $22,“ said Tim Hickman, whose California Headphone Company and Fanny Wang Headphone Company brands are made in China.


“When you look at a $300 Beats headphone, how much does it cost to tool the enclosure, how much does it cost to stamp the thing out?” said John Chen, director of sales for the audio manufacturer Grado Labs. “Stamping it out is pennies.”


“I wish that were true,” said Noel Lee, founder of Monster Products, which until December produced Beats by Dr. Dre headphones. “I’m going to say it’s in the $40 and up range to make a quality product.” (Monster also makes those $80 HDMI cables at electronics stores, the ones that cost much less at Monoprice.com.)


The growth in pricey headphones is yoked to the growth of tablets and phones. IPods and other media players come with basic earphones, but the expanded menu of music and video apps now available encourage people to replace those with higher-quality headphones.


“What is really pushing premium headphones is not just the growth in mobile smartphones and tablets, but video and music services like Netflix and Spotify, that make people want a better listening device,” said Benjamin Arnold, a consumer electronics industry analyst for NPD. “It’s serious consumption rather than 30-second YouTube clips.”


The rush into premium headphones was set off in 2008 by the Beats by Dr. Dre brand, which marketed headphones like Air Jordan basketball shoes. (HTC, the Taiwanese cellphone maker, was once the majority shareholder of the Beats venture and still owns a 25 percent interest.) Headphones had traditionally been sold on technical specs like frequency response, but Beats created appealing designs in an array of colors. It also tweaked the headphones with brain-rattling bass.


Monster lost the rights to make the Beats, but has introduced 12 of its own headphones, none with a celebrity name on the brand, although some have celebrity endorsers. NPD found that celebrity endorsement was extremely or very important to 30 percent of consumers, and was the top factor driving purchases of headphones costing more than $100. Consumers say they want sound quality, but brand counts heavily too.


“Basically good-enough sound is good enough if everything else is in line, like brand and color,” Mr. Arnold said. “You see young people walking around the mall with them around their necks. They aren’t even on their ears.”


Not all headphones work on the same economics as the fashion brands. Classic brands like AKG, Shure, Audio-Technica, Grado and Klipsch still market based on realistic sound and value. With no celebrity endorsers to share profits and a nearly unlimited shelf life, because the style doesn’t change with fashion, the marketing model is different.


This article has been revised to reflect the following correction:

Correction: February 21, 2013

An earlier version of this article misstated the ownership stake of HTC, the Taiwanese cellphone maker, in the Beats venture. It is 25 percent, not a majority.

F.C.C. Moves to Ease Wireless Congestion


WASHINGTON — The Federal Communications Commission on Wednesday took a step to relieve growing congestion on Wi-Fi networks in hotels, airports and homes, where Americans increasingly use multiple data-hungry tablets, smartphones and other devices for wireless communications.


The commission proposed making a large chunk of high-frequency airwaves, or spectrum, available for use by unlicensed devices, including Wi-Fi routers like those that many Americans use in their homes.


The agency’s five commissioners also expressed hopes that the new airwaves would unleash new innovations, just as unlicensed spectrum in the past has made possible such devices as cordless phones, garage door openers and television remote controls.


After a public comment period, the commissioners will try to issue final rules and regulations, a process that could take a year or more. But all of the commissioners expressed hope that the new airwaves could be put to use without unnecessary delay.


Possible roadblocks do exist, however, mainly because some of the airwaves proposed for the new applications are already in use by private organizations and government agencies, including the United States military.


Congress has mandated that the F.C.C. undertake the expansion of unlicensed spectrum, and the Obama administration has urged the freeing up or sharing of airwaves currently allocated to the federal government.


But various government agencies, including a division of the Commerce Department, have warned against allowing consumer uses to interfere with current applications.


Lawrence E. Strickling, assistant commerce secretary for communications and information, said in a letter to the commission that the Pentagon, the Department of Homeland Security and NASA use parts of the same airwaves for communication between aircraft and ground stations. Those communications enable activities like drug interdiction, combat search and rescue, and border surveillance.


Julius Genachowski, the F.C.C. chairman, said he was confident that the commission’s engineers would be able to work with the affected government and private entities to solve interference problems.


“It’s very important for the country that we all lean into this in a problem-solving way,” Mr. Genachowski said. “This is not a new challenge for the commission to address.”


While “it will require significant consultation with stakeholders” to avoid problems, he added, “consultation can’t be an excuse for inaction or delay.”


The commission also voted unanimously to approve a new regulation allowing consumers and companies to use approved and licensed signal boosters to amplify signals between wireless devices, like cellphones, and the wireless networks on which they operate.


Those boosters, millions of which are currently used in ungoverned applications, help consumers and businesses improve coverage where cell signals are weak. Boosters are also used by public safety departments to extend wireless access in tunnels, subways and garages.


The order, which takes effect March 1, creates two classes of signal boosters, for use by consumers and businesses, each with distinct requirements to minimize interference with wireless networks.

Disruptions: Disruptions: 3-D Printing Is on the Fast Track

Will the future be printed in 3-D?

At first glance, looking at past predictions about the future of technology, prognosticators got a whole lot wrong. The Web is a garbage dump of inaccurate guesses about the year 2000, 2010 and beyond. Flying cars, robotic maids and jet packs still are nowhere near a reality.

Yet the prediction that 3-D printers will become a part of our daily lives is happening much sooner than anyone anticipated. These printers can produce objects, even rather intricate ones, by printing thin layer after layer of plastic, metal, ceramics or other materials. And the products they make can be highly customized.

Last week, President Obama cited this nascent technology during his State of the Union address — as if everyone already knew what the technology was.

He expressed hope that it was a way to rejuvenate American manufacturing. “A once-shuttered warehouse is now a state-of-the art lab where new workers are mastering the 3-D printing that has the potential to revolutionize the way we make almost everything,” Mr. Obama said. He has pushed new technologies before, like solar and wind power, as remedies for our nation’s problems, and those attempts have only revived the debate about the limitations of government industrial policy.

But this one shows more promise. The question is, can the United States get a foothold in manufacturing one 3-D printer at a time?

Hod Lipson, an associate professor and the director of the Creative Machines Lab at Cornell, said “3-D printing is worming its way into almost every industry, from entertainment, to food, to bio- and medical-applications.”

It won’t necessarily directly create manufacturing jobs, except perhaps for the printers themselves. Dr. Lipson, the co-author of “Fabricated: The New World of 3D Printing,” said that the technology “is not going to simply replace existing manufacturing anytime soon.” But he said he believed that it would give rise to new businesses. “The bigger opportunity in the U.S. is that it opens and creates new business models that are based on this idea of customization.”

In addition to the lab that the president mentioned, a federally financed manufacturing innovation institute in Youngstown, Ohio, schools are embracing the technology. The University of Virginia has been working to introduce 3-D printers into some programs from kindergarten through 12th grade in Charlottesville to prepare students for a new future in manufacturing.

“We have 3-D printers in classrooms, and in one example, we’re teaching kids how to design and print catapults that they then analyze for efficiency,” said Glen L. Bull, professor and co-director of the Center for Technology and Teacher Education. “We believe that every school in America could have a 3-D printer in the classroom in the next few years.”

The education system may want to speed things up. The time between predictions for 3-D printers and the reality of what they can accomplish is compressing rapidly.

For example, in 2010, researchers at the University of Southern California said that another decade would pass before we could build a home using a 3-D printer. Yet last week, Softkill Design, a London architecture collective, announced that it planned to make the first such home — which it will assemble in a single day — later this year. The home isn’t that pretty, and will look more like a calcified spider web than a cozy house, but it will show it can be done. The price of 3-D printers has also dropped sharply over the last two years, with machines that once cost $20,000, now at $1,000 or less. That’s partly because Chinese companies are driving down prices. Yes, China sees the opportunity in these things, even though the technology may undermine some of its manufacturing advantages.

“When it costs you the same amount of manufacturing effort to make advanced robotic parts as it does to manufacture a paperweight, that really changes things in a profound way,” Dr. Lipson said.

This leaves us with one more question about the future: When will these 3-D printers be able to make us flying cars, robotic maids and jet packs?

Rise of Drones in U.S. Spurs Efforts to Limit Uses


Colin Diltz/The Seattle Times, via Associated Press


A Seattle police officer, Jim Britt, with a drone in October. Seattle later banned use of the devices.







They can record video images and produce heat maps. They can be used to track fleeing criminals, stranded hikers — or just as easily, political protesters. And for strapped police departments, they are more affordable than helicopters.




Drones are becoming a darling of law enforcement authorities across the country. But they have given rise to fears of government surveillance, in many cases even before they take to the skies. And that has prompted local and state lawmakers from Seattle to Tallahassee to outline how they can be used by police or to ground them altogether.


Although surveillance technologies have become ubiquitous in American life, like license plate readers or cameras for catching speeders, drones have evoked unusual discomfort in the public consciousness.


“To me, it’s Big Brother in the sky,” said Dave Norris, a city councilman in Charlottesville, Va., which this month became the first city in the country to restrict the use of drones. “I don’t mean to sound conspiratorial about it, but these drones are coming, and we need to put some safeguards in place so they are not abused.”


In Charlottesville, police officers are prohibited from using in criminal cases any evidence obtained by drones, also known as unmanned aerial vehicles. Never mind that the city police department does not have a drone, nor has it suggested buying one. The police are not barred from using drones for other efforts, like search and rescue.


Mr. Norris said the advent of new policing technologies poses new policy dilemmas for his city.


Charlottesville permits the police to install cameras temporarily in areas known for drug dealing, but it has rebuffed a police request to install cameras along its downtown shopping corridor. It has also chosen not to install cameras at traffic lights to intercept speeding cars, as is common elsewhere.


“Drones are capable of taking surveillance to a whole new level,” Mr. Norris said.


Last week, the Seattle Police Department agreed to return its two still-unused drones to the manufacturer after Mayor Michael McGinn answered public protests by banning their use. On Thursday, the Alameda County Board of Supervisors in Oakland, Calif., listened to the county sheriff’s proposal to use federal money to buy a four-pound drone to help his officers track suspected criminals — and then listened to raucous opposition from the antidrone lobby, including a group that uses the Twitter handle @N.O.M.B.Y., short for Not Over My Back Yard.


This week, members of Congress introduced a bill that would prohibit drones from conducting what it called “targeted surveillance” of individuals and property without a warrant.


A federal law enacted last year paved the way for drones to be used commercially and made it easier for government agencies to obtain them. The Department of Homeland Security offered grants to help local law enforcement buy them. Drone manufacturers began to market small, lightweight devices specifically for policing. Drones are already used to monitor movement on the United States’ borders and by a handful of police departments, and emergency services agencies around the country are just beginning to explore their uses.


The Federal Aviation Administration has received about 80 requests, including some from police and other government agencies, for clearance to fly drones, according to a Freedom of Information Act request filed by the Electronic Frontier Foundation, which seeks to limit their use for police surveillance.


Law enforcement authorities say drones can be a cost-effective technology to help with a host of policing efforts, like locating bombs, finding lost children, monitoring weather and wildlife or assisting rescue workers in natural disasters.


“In this time of austerity, we are always looking for sensible and cost-effective methods to improve public safety,” said Capt. Tom Madigan of the Alameda County Sheriff’s Department. “We are not looking at military-grade Predator drones. They are not armed.”


For now, drones for civilian use run on relatively small batteries and fly short distances. In principle, various sensors, including cameras, can be attached to them. But there is no consensus in law on how the data collected can be used, shared or stored.


This article has been revised to reflect the following correction:

Correction: February 18, 2013

An earlier version of this article rendered incorrectly part of the name of the federal department that offered grants to local law enforcement agencies to purchase drones. It is the Department of Homeland Security, not Services.

Bits Blog: Facebook Says Hackers Breached Its Computers

Facebook admitted that it was breached by sophisticated hackers in recent weeks, two weeks after Twitter made a similar admission. Both Facebook and Twitter were breached through a well-publicized vulnerability in Oracle’s Java software.

In a blog post late Friday afternoon, Facebook said it was attacked when a handful of its employees visited a compromised site for mobile developers. Simply by visiting the site, their computers were infected with malware. The company said that as soon as it discovered the malware, it cleaned up the infected machines and tipped off law enforcement.

“We have found no evidence that Facebook user data was compromised,” Facebook said.

On Feb. 1, Twitter said hackers had breached its systems and potentially accessed the data of 250,000 Twitter users. The company suggested at that time that it was one of several companies and organizations to be have been similarly attacked.

Facebook has known about its own breach for at least a month, according to people close to the investigation, but it was unclear why the company waited this long to announce it. Fred Wolens, a Facebook spokesman, declined to comment.

Like Twitter, Facebook said it believed that it was one of several organizations that were targeted by the same group of attackers.

“Facebook was not alone in this attack,” the company said in its blog post. “It is clear that others were attacked and infiltrated recently as well.”

The attacks add to the mounting evidence that hackers were able to use the security hole in Oracle’s Java software to steal information from a broad range of companies. Java, a widely used programming language, is installed on more than three billion devices. It has long been hounded by security problems.

Last month, after a security researcher exposed a serious vulnerability in the software, the Department of Homeland Security issued a rare alert that warned users to disable Java on their computers. The vulnerability was particularly disconcerting because it let attackers download a malicious program onto its victims’ machines without any prompting. Users did not even have to click on a malicious link for their computers to be infected. The program simply downloaded itself.

After Oracle initially patched the security hole in January, the Department of Homeland Security said that the fix was not sufficient and recommended that, unless “absolutely necessary”, users should disable it on their computers completely. Oracle did not issue another fix until Feb. 1.

Social networks are a prime target for hackers, who look to use people’s personal data and social connections in what are known as “spearphishing” attacks. In this type of attack, a target is sent an e-mail, ostensibly from a connection, containing a malicious link or attachment. Once the link is clicked or attachment opened, attackers take control of a user’s computer. If the infected computer is inside a company’s system, the attackers are able to gain a foothold. In many cases, they then extract passwords and gain access to sensitive data.

Facebook said in its blog post that the updated patch addressed the vulnerability that allowed hackers to access its employees’ computers.

Hackers have been attacking organizations inside the United States at an alarming rate. The number of attacks reported by government agencies last year topped 48,500 — a ninefold jump from the 5,500 attacks reported in 2006, according to the Government Accountability Office.

In the last month alone, The New York Times, The Wall Street Journal and The Washington Post all confirmed that they were targets of sophisticated hackers. But security experts say that these attacks are just the tip of the iceberg.

A common saying among security experts is that there are now only two types of American companies: Those that have been hacked and those that don’t know they’ve been hacked.

Bits Blog: Former BlackBerry C.E.O. Sold All Company Shares

Jim Balsillie, the former co-chief executive and co-chairman of BlackBerry, has sold all of his shares in the struggling company, a regulatory filing indicated on Thursday.

Mr. Balsillie’s arrival at what was then called Research in Motion in 1992 and his personal investment of $125,000 saved the company in its early days. But Mr. Balsillie’s latest investment move means that he will not gain if the new line of BlackBerry 10 phones revive the company’s fortunes.

A filing with the Securities and Exchange Commission, dated Thursday, showed that Mr. Balsillie held no shares in the company as of the end of December. Mr. Balsillie owned up to 33 percent of the company, now called BlackBerry, before it became publicly traded and he reported holding 5.1 percent of its shares in a previous filing.

When asked about Mr. Balsillie’s pullout, Kris Thompson, a longtime BlackBerry analyst at National Bank Financial, replied: “Who cares?” BlackBerry’s shares initially slipped 7.5 percent to $12.94 in Nasdaq trading Thursday, but had recovered later in the morning.

Following a protracted and severe decline in BlackBerry’s stock price and American market share, Mr. Balsillie stepped down as both co-chief executive and co-chairman along with Mike Lazaridis in January 2012. While Mr. Lazaridis remains on the BlackBerry board as the company’s vice chairman, Mr. Balsillie resigned as a director in March.

A separate securities filing issued on Thursday indicated that Mr. Lazaridis, who co-founded the company, still holds 5.7 percent of BlackBerry’s stock.

Mr. Balsillie could not immediately be reached for comment. Adam Emery, a spokesman for BlackBerry, said the company does not “comment on holdings of individual shareholders.”

Earlier this week Mr. Thompson, the analyst, issued a report that praised many of the features on the new BlackBerry 10 phones but concluded that they will not significantly rebuild the company’s market share. He cited an impending wave of new products from larger competitors and the general lack of desirable and high quality apps for BlackBerry 10.

While Mr. Lazaridis handled the technology side of the company, Mr. Balsillie, an accountant, is widely credited with putting BlackBerry on the stable financial footing that ultimately allowed it to develop the BlackBerry device. He also played a pivotal role in convincing skeptical wireless carriers to carry the company’s first wireless e-mail devices on their networks.

Both men, however, were widely criticized for not responding more effectively and swiftly to the arrival of Apple’s iPhone and phones using Google’s Android operating system. Those smartphones now overwhelmingly dominate a market that BlackBerry created and was once leading.

At various times, Mr. Balsillie and Mr. Lazaridis have sold substantial stakes in BlackBerry to fund educational institutions in Waterloo, Ontario, the company’s hometown.

Media Decoder Blog: Indian Music Service, Taking Page From Spotify, Goes Pro

Western music fans have no shortage of digital music services to choose from, and that abundance is spreading around the world. Apple’s iTunes is now in 119 countries, and others are racing to plant their digital flags everywhere. This week, for example, Spotify opened in Italy, Poland and Portugal, bringing its reach to 23 countries.

But just as interesting, and in the long run perhaps as significant to competition, is the rise of services that serve regional markets intensely. One is Saavn, a Spotify-like streaming service that specializes in Indian music, and has garnered 10.5 million monthly users with advertising-supported free listening. This week it will announce that it has taken another page from Spotify’s book, by offering a premium version at $4 a month that eliminates the ads, lets users listen to songs offline and will eventually add other features like higher quality audio.

Saavn, which has offices in New York, India and Mountain View, Calif., has a catalog of 1.1 million songs in nine languages and is available in more than 200 countries, with about 70 percent of its consumption within India, said Rishi Malhotra, one of its founders. Like Spotify, iHeartRadio and other Western services, it is an official partner of Facebook. About 80 percent of its use is on mobile devices, Mr. Malhotra said, and when the premium service, Saavn Pro, is opened in March, it will at first be available only for Apple devices.

The pricing is significantly lower than Western services. “We wanted to make it globally acceptable,” said Mr. Malhotra, who is based in New York. “The $10 price point that you see from a lot of music services we use here is way out of reach from what would fly in India or a lot of other emerging markets.”

Saavn believes it can succeed in India not only through its catalog of Bollywood hits, but through technological touches that may be meaningful only to Indian listeners. One example is the ability to search for a Bollywood song based on the actor who lip-synchs it — often more memorable to fans than the “playback” singer who actually provided the voice.

If successful, Saavn Pro could give the company an advantage in India’s quickly developing digital music market, which already has a handful of streaming services, like Dhingana, as well as a strong presence in downloads from Nokia. Yet that market is still tiny for a country of India’s size and overall media spending. According to the International Federation of the Phonographic Industry, recorded music had only $141 million in trade (or wholesale) value in 2011. A recent report by Ernst & Young said that music and radio combined count for only 2.4 percent of India’s media and entertainment spending, which for 2011 it estimated at $18 billion.

Part of the reason for music’s small proportion of India’s media economy is that popular music in India is dominated by the film industry. But a greater reason is piracy; the federation estimates that 55 percent of Internet users in India go to unlicensed music services on a monthly basis. That is slowly starting to change, music executives say, as courts there crack down on infringement and legitimate digital services proliferate. Apple’s iTunes opened there in December, and Nokia says it sells 1.4 million songs a day at its download store in India.

And Indian record companies are approaching digital business without the baggage that has been complicating deals with Western labels and services for more than a decade, Mr. Malhotra added.

“The labels in India are not reluctant about digital,” he said. “It’s not like they are protecting against some established, older revenue stream. It’s all found revenue for them.”

Tool Kit: How to Make Your Video Go Viral





It would take 72 hours to watch all the videos uploaded to YouTube every minute by would-be commentators, comedians, cosmetologists and various other content creators all hoping for a breakout hit.




And, let’s be honest, most of it is cringe-worthy.


While the vagaries of taste and timing determine which videos go viral and which YouTube channels develop large and loyal followings, it’s easier to tell which videos will make viewers feel as if they can’t click away fast enough.


It boils down to narcissism. If you’re an aspiring video blogger, remember, it’s not about you, it’s about who is watching you. . Be conscious and considerate of your audience and its needs, rather than getting mired in your own egotism or insecurity. (It’s good advice for life but essential to making quality video.)


Of course you want to have a decent camera. “If you have an iPhone or Android phone, you pretty much do,” said Eddie Codel, a video consultant in San Francisco, who produces content mostly for corporate clients. A hand-held video camera is nice and offers more features and flexibility, but your smartphone is fine.


The only additional equipment you might consider is a separate lavaliere or lapel microphone ($100-$200) for clearer audio. And if there isn’t enough ambient light to illuminate your face, spring for a clamp lamp ($10-$20) that you can find at most hardware stores. No one wants to watch you talking in the dark like someone in a witness protection program. For a flattering glow, Mr. Codel suggested putting wax paper in front of the lamp to diffuse the light.


O.K., so now you’re ready to perform — and you are always performing when the camera is rolling. “If you can’t communicate in an interesting, entertaining, energetic way — I don’t care how much education you have, how brilliant you are, how many degrees you have — it’s going to be painful to watch you,” said Karen Melamed, a television producer and online video consultant in Los Angeles. “Dr. Phil is not on TV because he’s the best therapist in the world, and Paula Deen is not the best chef in the world. They are good performers.”


That’s not to say you have to have an outsize personality or acting experience. But you do need to be comfortable in front of the camera, which is no easy feat. “There’s something sort of horrifying and anxiety-producing about shooting when you are alone,” said Ze Frank, who has more than 126,000 subscribers to his YouTube channel and whose quirky videos can attract as many as 20 million views.


The camera lens is a dark, bottomless void that doesn’t provide the feedback you get in normal face-to-face conversation, like a nod, a raised eyebrow and utterances like “hmmm” and “aah.” Lacking that, people tend to focus more on themselves and, in their self-consciousness, become either bland and monotone (as interesting as a lecture on the Hawley-Smoot Tariff) or hyper-excited and agitated (as annoying as a used-car commercial).


Mr. Frank, who lives in Los Angeles, said he tended to “over-gesticulate and mug too aggressively to the camera” when he first started posting Web videos in 2006. Now he has another person in the room operating the camera. “It’s wonderful to have someone else there to tell you if you are falling a little flat or that look was so cheesy it’s just ridiculous,” Mr. Frank said. Buzzfeed bought his channel last year, and he is now the company’s executive vice president for video, while continuing to create his own content.


If you don’t have the money to hire a camera operator or a willing friend to watch you record, just imagine you are talking to your typical viewer. “Your only concern should be how it’s going to benefit who is watching,” said Eileen Winnick, a media consultant and former actress whose past clients include the celebrity chefs Ina Garten and Bobby Flay. “When you do that, you take the focus off yourself and put it into what you want to get across, which changes the way you communicate,” she said.


You don’t even necessarily have to be on camera. John Mitzewich, of the YouTube channel “Food Wishes,” never appears in his cooking tutorials, which can attract as many as two million views. All you see are his hands at work in his San Francisco kitchen.


“It’s not, ‘Here I am, check out my personality.’ It’s, ‘Let’s make this thing,’ ” said Mr. Mitzewich, whose clever voice-over might compare peaking egg whites to “a voluptuous woman under a white cotton sheet.” Allrecipes.com bought his channel, which has 308,000 subscribers, last year, but he continues to have creative control. “The whole ‘follow your bliss’ thing totally works out,” he said.


Online video is different from television or film in that the audience is often watching on a small screen (laptop, tablet or smartphone). Viewers are up close, leaning in and may also be interacting with the content by posting comments, so it feels more intimate. “The viewer wants to be spoken to as a friend would talk to them,” said Ben Relles, head of programming strategy for YouTube, a division of Google. “They view these channels as friendships.”


As a result, they gravitate toward creators who seem genuine and responsive, such as Charlie McDonnell, a musician and professed nerd with soulful eyes, who has 1.8 million subscribers to the video blog, or vlog, he films in his London apartment. Or Jenna Marbles, who has attracted almost six million subscribers by her Tourette-like revelations of whatever is on her peculiar and profane mind.


Moreover, viewers appreciate content that they can’t get elsewhere. Creators are successful when they tap into “narrow but deep niches,” said Steve Woolf, senior vice president for content at Blip, a curated Web video site.


Paul Klusman, an engineer in Wichita, Kan., gained fame from his cat videos, in which he talks comically yet earnestly about the pleasures (companionship) and pains (kitty constipation) of cat ownership. The first video he made, “Engineer’s Guide to Cats,” was rejected by a short-film festival. But when he posted it on YouTube in 2008, it went viral with almost six million views and several marriage proposals.


He now has more than 33,000 subscribers with whom he regularly communicates (and sometimes dates). “I’m not a YouTube superstar, but I’m on the map,” said Mr. Klusman, who added that he also earns a nice supplemental income through advertising on his channel but “not enough for me to want to live on.”


While Mr. Klusman’s videos can be as long as seven minutes, most online media specialists say it’s better to crisply edit videos down to two to four minutes. That means getting rid of any vanity shots and self-indulgent rambling. “You want to be clean and concise, and if you don’t grab viewers in the first 15 seconds, they’re gone and aren’t coming back,” said Ms. Melamed, the producer and consultant. You don’t need fancy editing software either. Programs like iMovie and Windows Movie Maker, which come standard on many computers, are adequate.


A last bit of advice is to be consistent in churning out content. Post at least weekly if your vlog is topical. If you are more interested in building a library of content such as tutorials, the time between postings can be longer.


“Be patient and realize you are probably going to be a bit terrible in the beginning,” Mr. Frank said. “If you don’t end up making a living at it, there are other reasons to create online media. It’s certainly a validation of life.”

DealBook Column: Relationship Science Plans Database of Names and Connections

It sounds like a Rolodex for the 1 percent: two million deal makers, power brokers and business executives — not only their names, but in many cases the names of their spouses and children and associates, their political donations, their charity work and more — all at a banker’s fingertips.

Such is the promise of a new company called Relationship Science.

Never heard of it? Until recently, neither had I. But a few months ago, whispers began that this young company was assembling a vast trove of information about big names in corporate America. What really piqued my interest was that bankrolling this start-up were some Wall Street heavyweights, including Henry R. Kravis, Ronald O. Perelman, Kenneth G. Langone, Joseph R. Perella, Stanley F. Druckenmiller and Andrew Tisch.

It turns out that over the last two years, with a staff of more than 800 people, mostly in India, Relationship Science has been quietly building what it hopes will be the ultimate business Who’s Who. If it succeeds, it could radically change the way Wall Street does business.

That’s a big if, of course. There are plenty of other databases out there. And there’s always Google. Normally I wouldn’t write about a technology company, but I kept hearing chatter about it from people on Wall Street.

Then I got a glimpse of this new system. Forget six degrees of Kevin Bacon. This is six degrees of Henry Kravis.

Here’s how it works: Let’s say a banker wants to get in touch with Mr. Kravis, the private equity deal maker, but doesn’t know him personally. The banker can type Mr. Kravis’s name into a Relationship Science search bar, and the system will scan personal contacts for people the banker knows who also know Mr. Kravis, or perhaps secondary or tertiary connections.

The system shows how the searcher is connected — perhaps a friend, or a friend of a friend, is on a charitable board — and also grades the quality of those connections by identifying them as “strong,” “average” or “weak.” You will be surprised at the many ways the database finds connections.

The major innovation is that, unlike Facebook or LinkedIn, it doesn’t matter if people have signed up for the service. Many business leaders aren’t on Facebook or LinkedIn, but Relationship Science doesn’t rely on user-generated content. It just scrapes the Web.

Relationship Science is the brainchild of Neal Goldman, a co-founder of CapitalIQ, a financial database service that is used by many Wall Street firms. Mr. Goldman sold CapitalIQ, which has 4,200 clients worldwide, to McGraw-Hill in 2004 for more than $200 million. That may explain why he was able to easily round up about $60 million in funds for Relationship Science from many boldface names in finance. He raised the first $6 million in three days.

“I knew there had to be a better way,” Mr. Goldman said about the way people search out others. Most people use Google to learn about people and ask friends and colleagues if they or someone they know can provide an introduction.

Relationship Science essentially does this automatically. It will even show you every connection you have to a specific company or organization.

“We live in a service economy,” Mr. Goldman said. “Building relationships is the most important part for selling and growing.”

Kenneth Langone, a financier and co-founder in Home Depot, said that when he saw a demonstration of the system he nearly fell off his chair. He used an unprintable four-letter word.

“My life is all about networking,” said Mr. Langone, who was so enthusiastic he became an investor and recently joined the board of Relationship Science. “How many times do I say, ‘How do I get to this guy?’ It is scary how much it helps.”

Mr. Goldman’s version of networking isn’t for everyone. His company charges $3,000 a year for a person to have access to the site. (That might sound expensive, but by Wall Street standards, it’s not.)

Price aside, the possibility that this system could lead to a deal or to a new wealth management client means it just might pay for itself.

“If you get one extra deal, the price is irrelevant,” Mr. Goldman said.

Apparently, his sales pitch is working. Already, some big financial firms have signed up for the service, which is still in a test phase. Investment bankers, wealth managers, private equity and venture capital investors have been trying to arrange meetings to see it, egged on, no doubt, by many of Mr. Goldman’s well-heeled investors. Even some development offices of charities have taken an interest.

The system I had a peek at was still a bit buggy. In some cases, it was missing information; in other cases the information was outdated. In still other instances, the program missed connections. For example, it didn’t seem to notice that Lloyd C. Blankfein, the chief executive of Goldman Sachs, should obviously know a certain senior partner at Goldman.

But the promise is there, if the initial kinks are worked out. I discovered I had paths I never knew existed to certain people or companies. (Mr. Goldman should market his product to reporters, too.)

One of the most vexing and perhaps unusual choices Mr. Goldman seems to have made with Relationship Science is to omit what would be truly valuable information: phone numbers and e-mail addresses.

Mr. Goldman explained the decision. “This isn’t about spamming people.” He said supplying phone numbers wouldn’t offer any value because people don’t like being cold-called, which he said was the antithesis of the purpose of his database.

Ultimately, he said, as valuable as the technology can be in discovering the path to a relationship, an artful introduction is what really counts.

“We bring the science,” he said. “You bring the art.”

Disruptions: Disruptions: Apple Is Said to Be Developing a Curved-Glass Smart Watch

Dick Tracy had one. As did Inspector Gadget and James Bond. A watch that doubled as a computer, two-way radio, mapping device or television.

Though such a device has been lost to science fiction comics and spy movies of the era before smartphones, the smart watch might soon become a reality, in the form of a curved glass device made by Apple.

In its headquarters in Cupertino, Calif., Apple is experimenting with wristwatch-like devices made of curved glass, according to people familiar with the company’s explorations, who spoke on the condition that they not be named because they are not allowed to publicly discuss unreleased products. Such a watch would operate on Apple’s iOS platform, two people said, and stand apart from competitors based on the company’s understanding of how such glass can curve around the human body.

Apple declined to comment on its plans. But the exploration of such a watch leaves open lots of exciting questions: If the company does release such a product, what would it look like? Would it include Siri, the voice assistant? Would it have a version of Apple’s map software, offering real-time directions to people walking down the street? Could it receive text messages? Could it monitor a user’s health or daily activity? How much will it cost? Could Timothy D. Cook, Apple’s chief executive, be wearing one right now, whispering sweet nothings to his wrist?

Such a watch could also be used to make mobile payments, with Apple’s Passbook payment software.

Although it would take Dick Tracy to find the answers to those questions, and it’s uncertain when Apple might unveil such a device, it’s clear that Apple has the technology.

Last year, Corning, the maker of the ultra-tough Gorilla Glass that is used in the iPhone, announced that it had solved the difficult engineering challenge of creating bendable glass, called Willow Glass, that can flop as easily as a piece of paper in the wind without breaking.

Pete Bocko, the chief technology officer for Corning Glass Technologies, who worked on Willow Glass, said via telephone that the company had been developing the thin, flexible glass for more than a decade, and that the technology had finally arrived.

“You can certainly make it wrap around a cylindrical object and that could be someone’s wrist,” Mr. Bocko said. “Right now, if I tried to make something that looked like a watch, that could be done using this flexible glass.”

But Mr. Bocko warns that it is still quite an engineering feat to create a foldable device. “The human body moves in unpredictable ways,” he said. “It’s one of the toughest mechanical challenges.”

To add to the excitement of an Apple watch, late last year the Chinese gadget site Tech.163 reported that the company had begun development of a watch featuring Bluetooth and a 1.5-inch display.

“Apple’s certainly made a lot of hiring in that area,” said Sarah Rotman Epps, a Forrester analyst who specializes in wearable computing and smartphones. “Apple is already in the wearable space through its ecosystem partners that make accessories that connect to the iPhone,” she said, adding: “This makes Apple potentially the biggest player of the wearables market in a sort of invisible way.”

“Over the long term wearable computing is inevitable for Apple; devices are diversifying and the human body is a rich canvas for the computer,” Ms. Epps said. “But I’m not sure how close we are to a new piece of Apple hardware that is worn on the body.”

Investors would most likely embrace an iWatch, with some already saying that wearable computing could replace the smartphone over the next decade.

“We believe technology could progress to a point where consumers have a tablet plus wearable computers, like watches or glasses, that enable simple things like voice calls, texting, quick searches, navigation,” Gene Munster, an analyst at Piper Jaffray, said in a report last month. “These devices are likely to be cheaper than an iPhone and could ultimately be Apple’s best answer to addressing emerging markets.”

Mr. Cook is clearly interested in wearables. In the past he has been seen wearing a Nike FuelBand, which tracks a user’s daily exertion. The FuelBand data is shared wirelessly with an iPhone app.

Bob Mansfield, Apple’s senior vice president for technologies, who previously ran hardware engineering, has also been particularly interested in wearables, an Apple employee said. Mr. Mansfield is engrossed by devices that connect to the iPhone, through Bluetooth, sharing information back and forth from the human body to the phone, including the Nike FuelBand and Jawbone Up.

If smartphones do become smart watches and smart glasses, Apple seems to have the technology to make standout wearable computers.

Last year the company filed patents for displays that sit over the eye and stream information to the retina. Given that the iPod Nano is about the size of an overfed ant, the company clearly knows how to make small devices, too.

But, maybe there are other devices coming before wearables. Apple has long been rumored to be working on a television-like experience. And, there is the possibility of an Apple car.

In a meeting in his office before he died, Steven P. Jobs, Apple’s co-founder and former chief executive, told John Markoff of The New York Times that if he had more energy, he would have liked to take on Detroit with an Apple car.

In August, during the company’s patent trial with Samsung, Philip W. Schiller, Apple’s senior vice president for worldwide product marketing, said on the stand that Apple had explored making “crazy stuff” before development of the iPhone and iPad, including a camera or a car. While Apple continues its experiments with wearables, its biggest competitor, Google, is pressing ahead with plans to make wearable computers mainstream.

According to a Google executive who spoke on the condition that he not be named, the company hopes its wearable glasses, with a display that sits above the eye, will account for 3 percent of revenue by 2015. Olympus is also working on wearable computers.

Google is holding private workshops in San Francisco and New York for developers to start building applications for its glasses. At the event in San Francisco last week, Hosain Rahman, chief executive of Jawbone, the maker of the Up, a wrist device that tracks people’s energy and sleep, said that “a decade from now we won’t be able to imagine life without the wearables that we use to access information, unlock our doors, pay for goods and most importantly track our health.”

Reviewing Three Brands of Tax Preparation Software





TAX preparation is moving to the cloud.




The makers of the better-known tax prep programs — TurboTax, H&R Block at Home and TaxAct — say that many customers, particularly younger ones, prefer Web-based programs to old-fashioned, desktop versions. Web-based programs — techies call this cloud computing — reside on remote servers that customers access via their browsers. They offer the convenience of working on a return from any Internet-connected computer and having that return stored on the software makers’ secure servers.


After spending several days running my family’s tax information through Web and desktop offerings, I learned that I’m old-school. For a decade, I’ve completed our return on my Mac desktop, and I prefer that. Desktop programs may be costlier and, in some ways, clunkier — you must buy them on CD or download them — but they also offer more flexibility.


A single purchase, for example, lets you prepare and file multiple returns, as you might want to do if you’re part of a same-sex couple or if you help family members or friends with their taxes. And you can more easily jump back and forth between the tax return and the interviews the programs use to gather information. That lets you check entries as you make them, as my wife, a C.P.A., insists upon. What you lose in convenience, you gain in control.


Each of the tax preparation programs, whether desktop or online, has strengths and shortcomings. TurboTax is the easiest to use, importing lots of financial information with just a few clicks. H&R Block promises the most reassuring help — its staff will represent you at no extra charge if you’re audited. TaxAct offers the best price. A look at each provider’s offerings shows where it excelled and stumbled in preparing my family’s 2012 return.


TurboTax


TurboTax’s maker, Intuit, has its roots in technology, not taxes, and its facility with bits and bytes shows in its wares. Its desktop and online programs make doing taxes as simple as such a time-eating task can be. If you end up cursing come tax time, the target will be the I.R.S., not your software.


I downloaded the desktop version of TurboTax Premier for $89.99 — though I learned later that I could have paid $10 less if I’d bought it on CD at my local Staples. The download took only a few seconds, as did the import of information from our 2011 return. All of the unchanged data from 2011 — names, addresses, federal ID numbers, even descriptions of business expenses — popped into the right places on the 2012 forms. Even the names of the charities we support carried over. The software also imported my wife’s W-2 and all of the information on our investments from Vanguard, T. Rowe Price and Fidelity. All I had to do was key in details for a few local banks and update the amounts we’d given to charity.


The online version of TurboTax, by contrast, didn’t import as much. My attempt to transfer our 2011 return failed, and an import from one of the fund companies went awry. I inherited an I.R.A., and the money is invested in about a half-dozen funds. Instead of creating an entry for a single 1099-R, the program created a half-dozen, which I had to combine.


Otherwise, the online program looked and worked much the same way as the desktop software. I didn’t have to pay to try it because TurboTax, like H&R Block and TaxAct, doesn’t require online users to pay until they file their returns. Had I filed with the online version of TurboTax Premier, I would have paid $49.99 for a single federal return — the price as it was discounted at the time. But TurboTax says it could rise to as much as $74.99, its list price, before April 15.


 


TurboTax upgraded its assistance features for this year’s tax filing season — a welcome improvement. In the past, I’d found some help links hard to locate and navigate. When I wanted to pose a question to a tax expert, I had to dig around. But not anymore. When I had a question about recording tax-exempt interest, I clicked on the help link, and TurboTax offered a choice between a call and an online chat. Within seconds, I was e-chatting with Marilyn G., and she pointed me to the right spot on the return. We were done in less than five minutes, and I paid nothing extra. I’ve had a tougher time buying jeans online. (All three companies also provide extensive tax-law explanations embedded in their programs.)
