Computers: Google tablets seen overtaking iPad in five years

Posted by echa 9:54 PM, under | No comments

TABLET computers
HELSINKI - TABLET computers running Google's Android software will catch up with Apple's iPad and surpass it in 2016, research firm Informa said on Wednesday.

Informa said it expects Apple's current 75 per cent market share to fall to 39 per cent in 2015, when Android market share will grow to 38 per cent.

'From 2013, as cheaper and more advanced Android tablets enter the market, we forecast that sales will pick up considerably, eventually surpassing iPad sales in 2016,' analyst David McQueen said in a statement.

Samsung Electronics Galaxy Tab has been the best-selling Android tablet so far, but also other vendors including Motorola Mobility use it on their devices.

'We have seen a huge explosion in the tablet market in recent years, driven primarily by the iPad, and we estimate that the market will go from strength to strength, growing from under 20 million tablets sold in 2010, to over 230 million in 2015,' Mr McQueen said. -- REUTERS

Gadget: iPhone app brings Roman London to life

iPhone app brings Roman London to life
Apple sold 9.25 million iPads over the last quarter, almost 20 times the number of Motorola's Xooms.


Motorola announced dismal device sales in its earnings report on Thursday, with tablets faring near the worst among the company's products.

The company shipped 11 million mobile devices over the past three months, according to the quarterly statement. Yet only 440,000 of those were tablet devices.

In other words, the Motorola Xoom Android tablet flopped big time.

Out of the remaining 10.56 million devices shipped, 4.4 million of those were smartphones. That number of course pales in comparison to Apple's 20-plus million iPhones sold last quarter, and even to the 5 million Samsung Galaxy S2 smartphones sold in the first three months of the phone's release. Especially considering that's 4.4 million across all of Motorola's device models.

It's a quarter of rough numbers for the company, which of course is facing competition on all sides.

For perspective's sake, compare the 440,000 Xoom tablets with Apple's numbers this quarter: The Cupertino giant sold 9.25 million iPads over the last quarter, almost 20 times the number of Motorola's Xooms.

And it's important to note that when Motorola says 440,000 units "shipped," that signifies the number of devices sold to retail stores, not to customers. It's difficult to determine how many actual sales to customers occurred without further detail.

And even if the iPad weren't doing so well, the Xoom is still competing with the myriad Android tablets available from other hardware manufacturers.

Still, it's not all doom and gloom for the U.S.-based mobile device manufacturer. Smartphone sales are up from 2.7 million during the same time period last year, which is nothing to scoff at.

But with the majority of phone sales being "dumbphones" -- or relatively low-end cellular devices -- the company's strategy of relying heavily on smartphone sales as a strength has yet to pan out.

With any luck, the company will be able to turn things around as more smartphone devices debut in the fall.

Motorola CEO Sanjay Jha announced that the Droid Bionic -- a highly anticipated dual-core smartphone which was pushed back to the drawing board for further improvements -- will debut some time in September.

Tech Mobile: New wave of location-based apps mark a 'paradigm shift'

New wave of location-based apps mark a 'paradigm shift'
Trover uses GPS to figure out where you are and show you things other users have thought were interesting.


As location-based apps go, Foursquare or Gowalla will work just fine if you're looking for the spot where all your buddies are having a beer.

But what if they discovered an awesome, out-of-the-way spot six months ago? Or, better yet, what if you didn't even know you were looking for a watering hole until your phone told you there's one around the corner you shouldn't miss?

As the novelty of the simple check-in fades, and the abilities of GPS-based location technology expand, some new mobile apps -- call them "discovery apps" -- are looking to parlay mobile "noise" into useful, place-based tips.

"It feels like the paradigm shift in the late '90s when Google came along," said Babak Pahlavan, CEO of Cleversense, which released the app Alfred this month.

"There's an information overload -- to find something useful for you is a very daunting task. It's time for a new shift; it's time to make sense of it and make it useful for you."

Alfred has been called "Pandora for the real world." Users feed it information about their favorite places (mainly restaurants, bars and coffee shops). Then, theoretically, Alfred -- a mustachioed robot butler -- can suggest similar spots that are nearby, no matter where you are.

The free app, currently on Apple's iOS system, with Android and Windows Phone versions in the works, was rolled out this month and took top honors in the "Startup Idol" contest at the Fortune Brainstorm Tech conference in Aspen, Colorado.

The app, which was two years in the making, uses a Web-crawling algorithm to pull the information together and, according to Pahlavan, recognized the difference between positive and negative chatter about a place.

"There's so much information on the Web, but it's all scattered," he said. "You almost need an assistant or chaperone to go out and find things to figure out what matters to you."

If Cleversense's app relies on software, Trover, co-created by the founder of travel site Expedia, is fueled by other folks and their cell phones.

Unveiled Thursday after three months in trial mode, Trover is a photography app. But its similarities to hot tools like Instagram or Hipstamatic end there.

Instead, it's about documenting your discoveries, from a cool statue to an out-of-the-way restaurant to the best spot to view the surrounding scenery.

Rich Barton, the Expedia founder and a Microsoft alum who also founded real-estate site Zillow, said he and Trover CEO Jason Karas are both avid travelers.

New wave of location-based apps mark a 'paradigm shift'
"Alfred" makes suggestions based on a Web-crawling algorithm that took two years to create.


"And we've been brainstorming for years to figure out a way that we could carry with us, as we went, all our friends' recommendations on what to do, where to go and what to see," he said.

"Wouldn't it be great if we had a little voice whispering, 'Take a right there' ... or 'Hey, you're passing the best gelato place in Rome.' "

Using GPS on a smartphone (currently just the iPhone, but with an Android version in the works), the app shows users photos that other people have taken in the area.

Apps like Yelp! already let users search for restaurants or other destinations. But Trover's founders say their app does something else.

"People that are using Trover now ... say Trover has become part of the rotation of apps that they use -- Trover combined with Yelp! and Foursquare and Instagram," Karas said.

"With Trover, it's really a different kind of experience. It's really built more around exploration than targeted search. As you travel around a neighborhood, you can have these serendipitous kinds of experiences."

Used Friday at CNN's Atlanta offices, the app rendered images of folks standing beside the giant CNN logo, spots in Centennial Olympic Park, concert footage from nearby venue The Tabernacle and even a buffalo head on the wall of a Ted's Montana Grill restaurant.

With about 70,000 users who've found the app despite it being in stealth mode, the founders have already seen it used in an unexpected way: by street artists and their fans.

"That's two groups that have never really been able to get together, and they're getting together on Trover," Barton said. Users can, of course, create their own "troves" by taking and uploading pictures of their own.

Trover and Alfred aren't the only new apps geared, at least in part, to place-based discovery.

Broadcastr lets people upload audio files to an interactive map. Crowdbeacon lets users send questions to nearby users and tap into comments from other mobile apps about surrounding locations.

"With these new (GPS) sensors, it's all new data," Pahlavan said. "It's about making sense out of it for you, and these new technologies that are forming are about taking all these data points and aggregating it to make it more useful for you."

Tech Biz: Yahoo and Alibaba reach deal over Alipay

Yahoo and Alibaba reach deal over Alipay 
Alibaba CEO Jack Ma

NEW YORK -- Yahoo has finally come to an agreement with Chinese Internet giant Alibaba in a months-long battle over the ownership of payment site Alipay.

Yahoo (YHOO, Fortune 500) owns about 40% of Alibaba, which itself owns Yahoo China -- as well as three massive Chinese properties including Alipay. That stake is one of Yahoo's bright spots, so investors weren't pleased when uncertainty developed over Alipay.

Back in May, Yahoo disclosed to the SEC that Alibaba had transferred 100% of its ownership of its e-commerce site, Alipay, to a new company controlled by Alibaba CEO Jack Ma.

Yahoo scrambled to clean up the mess with a statement saying it was not made aware of the asset transfer until March 31 -- and that it "occurred without the knowledge or approval of the Alibaba Group board of directors or shareholders."

Alibaba disputed those claims, saying the transfer was discussed at several board meetings as long as three years ago.

Yahoo shares plunged over that week as the news continued to develop. Investors wondered why Yahoo was so out of the loop, and they questioned whether the company could retain its relationship with Alibaba.

A few weeks later, at Yahoo's analyst day, executives declined to answer most questions about Alibaba. Yahoo CEO Carol Bartz said several times that Yahoo "had an agreement with Alipay that none of us were going to discuss the past, and we're sticking to that."

Then, at Yahoo's annual shareholder day in June, stakeholders slammed the company for its handling of the Alibaba situation.

The announcement of the deal seemed to please investors early Friday, as Yahoo shares rose 6% in premarket trade. But the stock reversed course once the market opened and was down 2% in late morning trading as the broader market fell following a weak GDP report.

Terms of the deal: Under the terms of the deal, which also includes Japanese Internet firm and Alibaba investor Softbank, Alibaba will receive between $2 billion and $6 billion for an initial public offering of Alipay or any other type of Alipay liquidation.

In addition, Alibaba Group will license some technology services and intellectual property to Alipay. In return, Alipay will pay royalties to Alibaba.

The deal is expected to close by the end of 2011 and must be approved by regulators.

JPMorgan analyst Doug Anmuth said in a note to clients Friday that he is retaining his "neutral" rating on Yahoo.

"The agreement provides a definitive range of outcomes for the eventual monetization of Alipay, while also clearing an overhang on [Yahoo] stock," he wrote.

Anmuth noted that there is "very little visibility" into a timeline for an Alipay IPO, but as a major stakeholder Yahoo "can force a liquidity event after 10 years."

The Alipay battle is hardly the first time Ma, the Alibaba CEO, and Bartz have butted heads. In September, Alibaba offered to buy back Yahoo's stake for about $11 billion. Yahoo declined. To top of page

Tech Biz: List of smartphone losers gets longer

List of smartphone losers gets longer 

NEW YORK -- In the smartphone market, it's a great time to be Apple and Samsung. Nokia and Motorola? Not so much.

Last quarter, Apple (AAPL, Fortune 500) became the world's largest smartphone manufacturer for the first time, and Samsung moved up one spot to No. 2, according to a Strategy Analytics study released Friday.

They displaced Nokia, which had held the top position for more than a decade. It's a stunning achievement, particularly for Apple, which entered the market just four years ago and sells just two devices: The iPhone 4 and the iPhone 3GS.

Samsung smartphone shipments grew 520% over the past year, Strategy Analytics said. That growth was especially strong due to its Galaxy S II line of smartphones, which have proven popular abroad but haven't yet made it to the United States. The devices are expected to start selling here this quarter, and strong U.S. sales might help it overtake the top position.

Of course, Apple is also expected to unveil its next version of the iPhone in September, so Steve Jobs & Co. will likely remain a moving target.

For smartphone makers not named Apple and Samsung, last quarter was a very different story.

Nokia (NOK) retained its position of the top overall cell phone manufacturer, even though sales fell more than 20% over last year, according to an IDC survey released late Thursday. But Samsung is closing in fast. That could spell trouble for Nokia, because Samsung is performing well in traditional Nokia strongholds in which the Finnish phone giant is currently struggling: Europe and China.

The fact that smartphone sales are slumping for Nokia isn't a surprise: The company is transitioning away from developing and selling its own, underperforming mobile operating system called Symbian in favor of Microsoft's (MSFT, Fortune 500) Windows Phone 7 OS.

But Windows Phone sales have so far been underwhelming, and it remains to be seen whether the Nokia-Microsoft marriage will be mutually beneficial. It's a huge risk for Nokia to take, considering smartphones have become the biggest growth engine for the overall cell phone market over the past several quarters.

"The shrinking feature phone market is having the greatest impact on some of the world's largest suppliers of mobile phones," said Kevin Restivo, senior research analyst at IDC. "Stalwarts such as Nokia are losing share in the feature phone category."

Still, Nokia should be glad that it's not Motorola Mobility (MMI) or Research In Motion (RIMM).

Motorola announced Thursday afternoon that it lost $56 million last quarter and disappointed Wall Street analysts by saying results for its current quarter would be weaker than expected.

The company said its tepid outlook was due to delays in rolling out its new 4G smartphones and lower-than-expected profitability in its tablet business.

Motorola sold just 440,000 Xoom tablets in the quarter. The Xoom, which was the first of Google's (GOOG, Fortune 500) Android Honeycomb tablets, was expected by many analysts to be the first true test for the iPad. It hasn't been: Apple sold 9.25 million iPads last quarter.

Meanwhile BlackBerry maker RIM laid off 10% of its workforce last week in order to cut costs and focus its strategy.

RIM was once the leader of the smartphone market in North America, but sales have been waning recently as many other device makers have introduced devices with broader appeal. To top of page

Innovation: Apple now has more cash than the U.S. government

Posted by echa 8:44 PM, under | No comments

Apple now has more cash than the U.S. government
The world's most highly valued tech company now has more cash on hand than the U.S. Treasury.


Maybe the cash-strapped U.S. government should start selling iPads.

According to the latest statement from the U.S. Treasury, the government had an operating cash balance Wednesday of $73.8 billion. That's still a lot of money, but it's less than what Steve Jobs has lying around.

Tech juggernaut Apple had a whopping $76.2 billion in cash and marketable securities at the end of June, according to its last earnings report. Unlike the U.S. government, which is scrambling to avoid defaulting on its debt, Apple takes in more money than it spends.

This symbolic feat -- the world's most highly valued tech company surpassing the fiscal strength of the world's most powerful nation -- is just the latest pinnacle for Apple, which has been on an unprecedented roll.

 
U.S. debt: How did we get here?

Its Macs, iPhones and iPads remain hot sellers, its stock has surged past $400 a share and Apple just became the world's largest smartphone vendor by volume.

There's been a lot of speculation about what Apple might buy with its piles of cash -- Facebook and Sony being two of the more high-profile examples -- but the company doesn't seem to be in any hurry to make a move.

"We don't let the cash burn a hole in the pocket or make stupid acquisitions," CEO Jobs said last fall. "We'd like to continue to keep our powder dry because we think there are one or more strategic opportunities in the future."

Offering Uncle Sam a short-term loan is probably not one of them.

iPhone rumors, Nintendo 3DS, goats
Tech Check: Doug Gross, Brandon Griggs and Stephanie Goldberg discuss iPhones, the Nintendo 3DS -- and goats.


This week, on the Tech Check podcast, Doug Gross, Brandon Griggs and Stephanie Goldberg break down and discuss the latest iPhone 5 rumor (as well as the Apple rumor phenomenon itself).

The newest buzz came when a U.K. tech site posted what they said was a design for Apple's iPhone 5. Which, of course, doesn't exist yet. But, you know. Rumors are rumors.

(In fairness, a recent survey suggested that folks are plenty excited about the as-yet unannounced phone and would consider buying it despite the fact it doesn't exist).

We also break down what Nintendo's announcement that they'll be slashing the price of their handheld 3DS game system might mean.

Sales have been disappointing for the video game giant. Will the new price bolster sales, as has happened for e-readers, or be a sign of a fast slide to oblivion?

Our Reader Comments of the Week are about Apple. And goats. And Darth Vader. Seriously. You just have to listen.

And we hand out the Tech Fail of the Weekfor a tweet in the wake of Amy Winehouse's death that puts a new face on crass commercialism.

Web: Congress gathering debt-crisis feedback via Facebook

Posted by echa 8:30 PM, under | No comments

Congress gathering debt-crisis feedback via Facebook
All House Speaker John Boehner's Facebook posts in the past two weeks have articulated his positions on the debt crisis.


As members of Congress navigate the shifting political sands of the debt-ceiling crisis, many of them are turning to a digital platform more associated with sharing personal updates and funny videos about cats: Facebook.

In recent days, lawmakers have swarmed the popular social network to post videos outlining their positions, conduct opinion polls, reach new constituents and ask for feedback.

"Over the past week, our team has seen a marked increase in the number of members of Congress speaking directly to constituents through their official Facebook pages," said Andrew Noyes, manager of public policy communications for Facebook.

The number of posts including video or radio snippets also has increased over the past week as lawmakers seek to engage their followers in new ways, Noyes added. As more members speak in front of C-SPAN's cameras, he said, "we fully expect to see the pace of these postings pick up."

All of House Speaker John Boehner's Facebook posts in the past two weeks have articulated his positions on the debt crisis. It's not clear whether they're nudging the needle of public opinion, but they are sparking dialogue: A message by Boehner on Monday drew more than 15,000 comments.

Meanwhile, congressional Democrats have used Facebook to rally opposition to Boehner's debt-ceiling bill. Democratic Whip Steny Hoyer, D-Maryland, posted a C-SPAN clip of his comments from the House floor, while Sen. Mark Udall, D-Colorado, asked Facebook users to sign his online petition urging Congress to adopt a "sensible" bipartisan solution.

Observers say politicians have embraced social media platforms such as Facebook and Twitter because they allow them to communicate directly with constituents without having their messages altered.

"You can convey emotion in a Facebook update or a YouTube video. It offers an authenticity," said Brad Fitch, president of the Congressional Management Foundation, a nonpartisan group dedicated to improving citizen engagement with Congress.

"They [lawmakers] aren't letting the dialogue be created by someone else. They're creating the dialogue," Fitch said. "And they are very excited about avoiding the pesky media."

You can convey emotion in a Facebook update or a YouTube video. It offers an authenticity.
--Brad Fitch

Some members of Congress are addicted to the instantaneous feedback they receive on Facebook and Twitter, Fitch said.

"Politicians long for public reaction, and they long to be loved," he said.

Members of Congress also use Facebook and Twitter to quickly rebut published reports or opponents' claims they disagree with.

One challenge of communicating through unfiltered social media -- especially on hot-button political issues -- is that comments can degenerate into name-calling or worse. On Friday Rep. Bobby Schilling, R-Illinois, had to remind his Facebook fans that profane, threatening or inappropriate comments would be deleted.

So does all this social-media messaging by Congress really influence public opinion?

Probably not, says Nick Judd, assistant editor of the Personal Democracy Forum, a website about the intersection of politics and technology.

"It seems that while the population of Americans on social media is large and growing, folks who talk politics on social media are already polarized. You could think of it a little bit like being at a large party where the political junkies are huddled up in a back corner, talking amongst themselves," he said.

"How much gets from that group to their apolitical friends, I don't know -- but one prevailing theory now is that Facebook in particular makes it hard to breach that barrier." Judd cited a recent book, Eli Pariser's "The Filter Bubble," which argues that Facebook tends to surround users with like-minded friends and shield them from opposing views.

That's not stopping politicians from turning to the social network to get their message out. A recent survey of congressional staffers by the Congressional Management Foundation found that nearly 75% think Facebook is "somewhat or very important" for communicating their members' views, followed closely by YouTube and less so by Twitter.

"Facebook has become a critical channel for government communication," Noyes said. "Politicians are only getting more creative with social media as the the debate over the debt ceiling and other crucial public-policy issues continue."

Gadgets: I'm stuck in a DVR time warp, and I like it

Posted by echa 8:25 PM, under | No comments

I'm stuck in a DVR time warp, and I like it
Every summer, I start descending the scroll-list of stuff we have recorded on our nearly full DVR.


Hey, do me a favor. Don't tell me how the royal wedding of Prince William and Kate Middleton ends. I haven't watched it yet. I'm assuming the deal was sealed?

Every summer, after most of the TV shows my wife and I watch end their regular-season runs, I start descending the scroll-list of stuff we have recorded on our nearly full DVR.

The digital video recorder's hard drive, which holds about 30 hours of HD-quality programming (much more if it's not HD), is stuffed with old stand-up comedy specials we never watched, never-to-be-deleted cartoons for the kids, a handful of current programs that air in the summer like "Louie" and "Children's Hospital," and some movies we didn't care about enough to rent but which were worth recording when they aired on cable.

But the bulk of what's there right now, in these hot summer months of reruns and reality shows, are very, very old programs that were easy to cast aside in the fall and spring.

I make it my mission to catch up in the summer on a lot of that programming, deleting as I go, clearing up space before our other shows start up again in August and September.

There's that royal wedding, which was recorded in the wee hours of a Friday months ago. I hear it was kind of a big deal. I would hope so: It takes up a whopping six HD hours on our DVR. I'm beginning to have my doubts that it will ever be watched, but I'm also curious about those interesting hats I heard so much about and that kiss on the balcony I missed.

Maybe it's worth experiencing something even if everyone else who gushed over it at the time has moved on.

In that way, all those neglected programs on the DVR are a bit like a time portal, a way of experiencing life as it was (at least on TV) weeks, months or years ago.

Among my DVR's contents are about half a season of "Saturday Night Live." The "Weekend Update" segment, viewed now, reminds me how obsessed the country was with former Delaware Senate candidate Christine O' Donnell. Was it witchcraft everyone was fired up about? The jokes would seem to suggest as much. Huh. I'd forgotten all about that.

And those easy punchlines from last year about Amy Winehouse's drug use don't seem that funny any more. (Were they really funny at the time? I may never know.)

There's three full seasons of "Breaking Bad" on the DVR that I promised myself I'd catch up on before Season 4 started this month. That didn't happen -- I'm still in the middle of Season 2 -- but a pleasant bonus has been imagining how viewers reacted at the time the episodes originally aired.

I can go online and find the Internet record of recaps, reviews and even archived tweets about each episode.

I might miss the thrill of being part of the discussion of a buzzed-about show while it's airing (also on our DVR: the full first seasons of "Game of Thrones" and "Boardwalk Empire"), but I can watch at my own pace, marathoning through two or three episodes at a time, as you might with a DVD set.

For old episodes of shows like "The Office" and "Modern Family," which we let stack up when time was short, there's the pleasure of also seeing commercials for movies that arrived, bombed at the box office, hastily moved on to a DVD afterlife and which we can now probably catch on HBO.

And there are the sometimes-tragic ads for new TV shows that have already been cancelled after a short run. So long, "The Cape" and "Mad Love," shows we never even knew had arrived.

Maybe our household is unusual and other DVR owners don't have such squirrel-like tendencies, storing up a stockpile of TV for the barren months. But given that we're a nation of hoarders (as I learned from another DVR'd show, "Hoarders"), and that about 40.5 million homes have digital video recorders, according to research firm Magnaglobal, I bet we're not that unique.

I bet there are a lot of people reliving the past, time-shifting into another era.

According to a report from the Nielsen Co. from late last year, 88% of DVR owners watch their recorded shows within three days of recording.

That leaves 12% of us who regularly engage in lengthier time warping, reliving the TV past with a sage knowledge of the present. The only downside: The onus is on us to be ever-vigilant in avoiding spoilers for the programs we've yet to watch.

Web: Are Internet Explorer users dumb?

Are Internet Explorer users dumb?
A survey used tests offered through Web searches or in online ads to measure the IQ of browser users


Are users of other Web browsers smarter than the people who use Microsoft's Internet Explorer?

A new survey doesn't quite say so. But it sure as heck suggests it.

The survey by AptiQuant, a Vancouver-based Web consulting company, gave more than 100,000 participants an IQ test, while monitoring which browser they used to take the test.

The result? Internet Explorer users scored lower than average, while Chrome, Firefox and Safari users were slightly above average.

And users of the more obscure Camino and Opera browsers, as well as those using Explorer with Chrome Frame (a plug-in designed to let users view emerging HTML5 content), had what AptiQuaint called "exceptionally higher" IQ levels.

Those numbers, it should be noted, probably aren't very scientific. The field of test-takers was self-selecting -- people who chose, on their own, to take an IQ test instead of a scientifically selected study group. They found the test through Web searches or ads the company placed online.

The report suggests that people using Explorer, the built-in, default browser for Windows-based computers, may be more resistant to change. A similar study in 2006 showed users on the then-current IE browser scored above average.

Internet Explorer is the world's most popular browser, with about a 43% share, according to StatCounter. Firefox has just under 30%, and Google's Chrome has 19%, according to a report from May.

Users of Internet Explorer 6, released in 2001, scored the lowest on the tests, at just over 80. Users of Opera, the Norway-based browser, scored the highest at well over 120. (What AptiQuant called its complete results included a bar graph showing the scores, but didn't appear to have text giving the exact numbers.)

IQ scores have a "population mean" of 100.

If this all smacks of a little good, old-fashioned Microsoft hate, the language the company uses in its report doesn't do much to downplay that.

"It is common knowledge that Internet Explorer Versions 6.0 to 8.0 are highly incompatible with modern web standards. In order to make websites work properly on these browsers, web developers have to spend a lot of unnecessary effort ...," said the report from AptiQuant, which offers online tools for employers to measure employee, and potential employee, aptitude.

"Now that we have a statistical pattern on the continuous usage of incompatible browsers, better steps can be taken to eradicate this nuisance."

What do you think? Cheap shot or telling results? Let us know in the comments.

Apple manufacturer to replace some of workforce with robots
Foxconn currently has 10,000 robots; in the next year, this number should jump to 300,000.


Foxconn, a company that manufacturers parts used in Apple's iPhone and iPad, said it aims to replace workers with 1 million robots in the next three years, Xinhuanet reports.

The robots will be assigned simple tasks currently done by human workers, such as welding and assembling parts. Foxconn currently has 10,000 robots; in the next year, this number should jump to 300,000 and up to one million in the next three years.

With the move, the company aims to cut labor expenses and improve efficiency, Foxconn CEO Terry Gou said at a workers' dance party on Friday.

Foxconn has a massive operation in China with about 1 million workers. The company caught the headlines after a string of suicides which prompted HP, Apple, Sony and other companies to launch an investigation into Foxconn's business practices.

More recently, an explosion in Foxconn's Chengdu plant in China left two people dead and 16 injured.

Tech Mobile: Wireless contracts yield better customer service, survey says

Posted by echa 6:45 PM, under | No comments

Wireless contracts yield better customer service, survey says
Among major carriers that offer cell-phone contracts, Verizon Wireless earned the highest ranking in the customer-care survey


Few people would say they actually enjoy contacting their wireless carrier for customer service. But if you have a contract for your cell phone, you'll probably get slightly better service, according to a new survey from J.D. Power and Associates.

This survey of U.S. consumers measures overall customer-care performance on a 1,000-point scale. Cell phone users who sign a contract for wireless service gave an average rating of 761 points for their customer-care experience, in contrast to an average 738 points for no-contract and prepaid users.

Why the difference? It's mostly about hold time. Noncontract customers reported holding 5.5 minutes on average before speaking to a live representative, just over a minute longer than the average wait for contract customers.

Kirk Parsons, J.D. Power's senior director of wireless services, said that when customer care reps can access more customer information, hold times drop.

"Full-service providers generally have access to existing account information that helps identify the customer immediately once contact is made," he said.

But the quality of interactions also counts. On this front, noncontract wireless customers reported being considerably less satisfied with representatives' knowledge of their plans -- and with their seemingly apathetic attitude.

Among the major carriers that offer cell phone contracts, Verizon Wireless received J.D. Power's highest ranking, followed closely by T-Mobile. (Recently Verizon has been touting how one of its customer-care representatives helped a customer get help during a life-threatening emergency.)

AT&T and Sprint tied for the bottom ranking -- which may not bode well for current T-Mobile customers if the planned AT&T acquisition of T-Mobile ends up happening.

Among noncontract providers, Boost Mobile received the highest ranking and Virgin Mobile and Net10 the lowest.

Smartphone owners tend to need more customer service. According to the survey, 48% of smartphone owners have contacted their carrier with an issue in the last six months, compared to 35% of other cell phone users. Since the vast majority of U.S. smartphones come with carrier contracts, then maybe it's not so surprising that 40% of calls from contract customers concerned phone malfunctions or repairs.

In terms of customer service, smartphone users and feature phone users reported nearly identical average levels of overall satisfaction.

There's a dark side to this story. Recently the Wall Street Journal reported that even though the U.S. wireless industry is booming, it has also been shedding U.S. jobs (especially customer service jobs) at a fast clip.

According to WSJ: "In May, on the heels of a record year for industry revenue, employment at U.S. wireless carriers hit a 12-year low of 166,600, according to U.S. Labor Department figures. ... That's about 20,000 fewer jobs than when the recession ended in June 2009 and 2,000 fewer than a year ago.

"While the industry's revenue has grown 28% since 2006, when wireless employment peaked at 207,000 workers, its mostly nonunion work force has shrunk about 20%."

And: "The number of customer-service workers at wireless carriers dropped to 33,580 last year from 55,930 in 2007, according to the Labor Department.

" 'It used to be you had to scale your customer-care resources linearly with the number of customers you had,' said Dan Hays, a telecom consultant. 'We don't do that anymore.' "

Tech Biz: Twitter lands major new funding round

Posted by echa 6:41 PM, under | No comments

Twitter
Twitter has landed a major influx of cash to help it expand: The five-year-old social media company said Monday that it has just wrapped up a "significant" funding round led by venture firm DST Global.

Twitter didn't disclose how much it raised. However, Twitter amended its certificate of incorporation forms late last week to authorize the issuance of up to 25 million new shares, priced at just over $16 per share. That would let the company raise around $400 million in new funding, according to venture capital data provider VC Experts, which obtained a copy of the amended incorporation forms.

But the actual amount Twitter raised from investors could be higher, if it follows the latest tech trend of letting existing shareholders -- such as employees and early investors -- sell some of their shares to investors during a company financing round. Facebook, Groupon and Zynga -- which are also backed by DST Global -- all went that route in their later investment rounds.

"Twitter is one of the few companies that has truly changed the world," DST Global founder Yuri Milner told AllThingsD, which reported that the new round values Twitter at $8 billion. "Twitter's astonishing growth is a testament to how important it is becoming to more people every day, and why we couldn't pass up the chance to be a bigger part of its future."

Twitter, based in San Francisco, said it will use the additional funding to hire more employees, grow internationally and "aggressively innovate."

Founded in 2006, Twitter has expanded rapidly in the past year, increasing its staff from 250 to more than 500 employees. On Monday the company opened its second office, launching a New York City outpost.

Prior to its latest funding round, Twitter had already raised more than $350 million from investors -- but the company is widely believed to be unprofitable. Its most recent financing round was in December, when it raised an estimated $200 million from a group led by Kleiner Perkins.

Since then, the fast-growing company has made a number of management changes. Co-founders Ev Williams and Biz Stone stepped away from the daily operations of Twitter to focus on a new venture, while previously exiled co-founder Jack Dorsey returned to lead Twitter's product strategy. Twitter also acquired a string of companies developing around its platform as part of its expansion effort. To top of page

News: Some small businesses overwhelmed by daily deal rush

Posted by echa 6:36 PM, under | No comments


When the owner of the Hillbrook Inn went looking for ways to boost business, she turned to a new and increasingly popular tool: daily deal sites like LivingSocial and Groupon.

The 10-guestroom bed and breakfast near Charles Town, West Virginia, listed a one-night stay on LivingSocial in March for half off the usual rate. Owner Carissa Zanella and her staff weren't waiting long for responses.

"It was a mad rush," said Zanella. "We had two computers and three phones and employees waiting to answer. We were answering nonstop, to the point that we had messages backed up on our machine."

The Hillbrook Inn's experience is not unique. As daily deal sties continue to grow in popularity, businesses are turning to them as a way to bring in new clients. At the same time, however, some merchants feel overwhelmed by the rush for discounts and are questioning whether the bottom-line boost is worth the logistics headache.

Once Zanella's surge of new bookings subsided, it was clear to her that she wasn't fully prepared for the sudden rush of interest. Before the deal ran, Zanella found herself questioning whether it was going to be worth it. Now, she said she believes LivingSocial should provide small businesses with more information on what to expect.

"I don't feel they gave us enough information on that," she said. "It happens so fast. I expected people to call, but I did not expect buyers to not look at our website before they purchased the deal."

The inn sold 498 one-night stays in the six days the deal was listed. But as people kept calling, its cramped, two-desk office began shrinking under the growing paperwork. Rooms began to fill up, and hopeful vacationers were told the Hillbrook was booked solid on the date they wanted to redeem their voucher.

Marie Griffin, communications director for LivingSocial, said the company does try to manage merchants' expectations.

"Once we have crafted that deal, we essentially give them a little welcome kit," she said. "What that welcome kit does is help prepare them for what will happen once the deal runs."

Griffin said the kit includes tips on how to prepare websites and phone systems, along with different options for accepting the LivingSocial vouchers. It also suggests businesses have a meeting with staff and prepare them for the spike in interest.

"You may need to bring in extra help," Griffin said. "You are going to have higher call volume, higher traffic to your website."

But not all merchants have a staff waiting to handle the rush in calls. Laura West is owner of BellaWest Eco-Friendly Salon and runs the appointment-only business in Alexandria, Virginia, by herself. A month after she offered discounted services on Groupon, she said the phone still rings off the hook and the e-mails haven't stopped.

In all, West sold 276 half-price haircuts, a number that she said is pushing her to the limit. West was hoping to sell 400 haircuts through Groupon, but in retrospect said, "If I had sold 400, it would have crushed my business."

West said it's the last deal she'll do with Groupon, but not because of the rush in business. West said the Groupon sales representatives were unprofessional and she was rushed into finalizing the deal.

"I was having second thoughts if I wanted to run it and I was taking my time. Next thing you know, she (the Groupon representative) sends an e-mail saying, 'This is how it is going to run.' "

Groupon spokesperson Julie Mossler disputed West's claims.

"Deals do not run on Groupon without 100% approval from the business owner, from deal structure to fine print to editorial content. We have a very specific editorial voice that our consumers trust, devoid of words like 'best' and instead pointing to third-party reviews," she said.

"It can be unnerving for a business to 'hand over the keys' to their writeup, but ultimately they understand that it benefits us both."

West said she is worried that her discounted rates, coupled with the cut that Groupon takes, won't leave enough profit to make the deal worthwhile. LivingSocial and Groupon do not disclose the size of their fee, but some merchants reported it was between 30% and 50%.

Groupon's chief rival, LivingSocial, was founded two years ago in Washington. In that time, it has grown rapidly, expanding into more than 250 markets in 12 countries. The company values itself between $10 billion and $15 billion.

The market for daily deal coupon sites continues to grow. Groupon has filed for an initial public offering of $3 billion, valuing the company at $30 billion. Internet stalwarts like Facebook and Google have begun offering users daily discounts, too. And a recent report by Local Offer Network said more than 320 daily deal sites operate in the United States.

To date, LivingSocial said it has helped sell more than 400,000 stays at hotels, motels and inns across the United States. While Griffin did acknowledge some merchants had been stretched by the rush, she also said, "We have had a great response from large properties, as well as bed and breakfasts, saying that they brought in a whole new demographic."

Not all establishments have been overwhelmed like the Hillbrook Inn. On July 13, LivingSocial listed a two-night stay at the 1890 Caroline House in Fredericksburg, Virginia. A day after the listing, Bonnie DeLelys, the owner of the inn, said the surge in business was welcome.

"We have two people at the desk, so I think we are handling it well," she said. "But the phone has been ringing, just boom, boom, boom." She said LivingSocial prepared her well for what to expect.

In total, the 1890 Caroline House sold 225 packages, a number DeLelys said she was very happy with.

Many merchants may not make much money on the initial deal. Instead, they hope to be introduced to new return customers who will make up in the long term for the short-term losses.

Some research shows that merchants may not reach that goal, however.

A Rice University study reported that 19.9% of deal users returned after using a deal. "By their very nature, daily deal promotions appear to be limited in their abilities to attract free-spending consumers and to convert deal users into repeat buyers with the propensity to be relational with, and loyal to, the business afterwards," wrote Utpal Dholakia, an associate professor of management at Rice.

LivingSocial said they regularly have merchants return to do deals again.

The Hillbrook Inn said it is still feeling a bump in business months after the deal was listed. With repeat customers already coming back for longer stays, Zanella said that while she was skeptical before listing with LivingSocial, she is pleased with the results. She's even working with the digital-coupon company to offer another deal in the near future.

Communications: Picking up Signals from Television Viewers

Posted by echa 4:26 PM, under | No comments


 
Talking about TV: Bluefin Signals, above, gives a fine-grained view of how much audiences are responding to television content through social media.

Bluefin Labs aims to measure the connections between social media and television shows.

Bluefin Labs wants to know not how many people are watching a TV show, but what they're saying about it. This week, the company, based in Cambridge, Massachusetts, launched its first product: Bluefin Signals, a tool for monitoring and analyzing audience reaction to TV shows, which it collects by simultaneously monitoring television and social media feeds.

Bluefin has spent the past three years building up the infrastructure, algorithms, and computing power needed to process the enormous quantities of data generated by social media sites including Twitter and Facebook. Currently, the platform processes more than three billion public comments each month.

For years, the success of a television show has been assessed using an estimate of the number of people watching a show provided by Nielsen, a company that gathers information using set-top boxes and diaries. But advertisers and producers increasingly also want to know who's talking about a show, and what they're saying. Bluefin Signals is designed to measure this side of an audience's reaction using social media.

Bluefin faces competition from a growing field of startups, including Netbase and Viralheat, which also mine social networks for reactions to products and media. Other companies, such as GetGlue and Tunerfish, are building social networks around television content, and gathering data in the process. Bluefin executives say that the massive amount of data they collect and analyze sets their product apart. The most serious potential competition could ultimately come from Nielsen. The ratings giant has not yet announced a strategy for monitoring social media, but it is working on connecting its existing data to social media analysis.

Bluefin tracks which shows are scheduled to be shown on TV and also uses analyzes broadcast and cable television feeds from all over the United States frame by frame using fingerprinting to confirm that a particular show or advertisement is on screen. The company simultaneously crawls through social media feeds for mentions of television shows, and links those mentions to specific shows and commercials.

Many advertisers and television networks already monitor Twitter, Facebook, and other similar sites to learn how a show's audience received it. But executives struggle to understand the implications—if a show gets 2,000 mentions on social networks, is that number was impressive or small compared to similar shows? "That's one of the core problems we're looking to solve for people doing this type of analysis," says Tom Thai, vice president of business development at Bluefin. "Not only give them the numbers, but also the universe of context."

Bluefin Signals provides two main ways of measuring an audience's reaction. The first, called Response Level, tallies up the number of people commenting on a given show. It converts this to a 10-point scale so that people can assess that number in relation to other shows aired at other times. The second, Response Share, determines how much attention a show got while it was on the air. Bluefin found that the NBA finals got about 45 percent of the response to television on social media on the night of May 24, compared with only 6.1 percent for American Idol. Bluefin Signals allows users to get a finer look at the data, by comparing shows within the same genre.

Thai says Bluefin's product is most useful for assessing whether less popular shows are a good advertising buy. Many of these have similar audience numbers, so social media response could make certain shows stand out. He adds that eventually Bluefin can even reveal which shows get the best response to particular types of advertisements on social media.

A product like Bluefin's could help fill in some key gaps for advertisers, says Jon Kleinberg, a professor of computer science at Cornell University who studies the social and information networks that underpin the Web and online media. "One thing that has made advertising work very powerfully in domains such as Internet search is that you know a lot about the person receiving the ad--what they're doing at the moment, through their query or other activities on the site, and sometimes what they've done in the past as well," Kleinberg says. "For other domains--broadcast media such as TV, for example--it's traditionally been harder to form a picture of the ad's recipients, at the moment they receive it." Bluefin has the opportunity to "fill in the missing details" by measuring and reporting how audiences react to broadcast content in real time.

Bluefin is studying other fine-grained data, such as the success of commercials when paired with particular shows, and it plans to release additional products and features that make use of this sort of data.

Web: A Network for Wild Experimentation

Dark fibers: Researchers will use dormant networking resources—which extend through the areas indicated on this map—to perform a variety of experiments.

ESNet and Internet2 have built a networking test bed for ideas that are too disruptive for the networks that people actually use.

In a few unused back alleys of the Internet, researchers are testing radical new ways of transferring information, often at speeds almost unimaginable to the home Internet user.

Internet2, a consortium devoted to developing advanced networking applications and technologies, and the Energy Sciences Network (ESNet), which provides powerful data connections for scientists at national laboratories, universities, and research institutes, are putting together experimental networks on top of dormant networking resources known as "dark fiber." While the researchers say it will be years before the advances reach individuals and businesses, they think the work will ultimately ensure that the Internet functions smoothly in the future. For example, the experimental networks could allow researchers to update protocols, anticipate security needs, try out better hardware, and look at ways of making networks more energy-efficient.

The organizations worked together on two prototype networks. One transfers data at a mind-boggling 100 gigabits per second. (Google made waves last year by announcing its plan to build a one-gigabit-per-second network for a chosen community.) The second is intended for riskier experiments into network architecture. Researchers want to find protocols that transfer data faster and more reliably, try out innovative network hardware, and experiment with ways to handle difficult security scenarios. In other words, they want to do the type of work that could cause problems for regular traffic if it were done on any sort of shared network.

"When you want to do something disruptive, when you want to try something really radical, you can't do that on a network that people are trying to actually use," says Robert Vietzke, Internet2's director of network services. At the same time, it is useful to test these ideas on real network infrastructure. In the past, he says, researchers would buy spools of fiber, install them in their labs, and try to emulate a national network. Using dark fiber lets them test ideas at larger scales, and bring in real traffic (without disrupting it). This makes it much easier to go from experiment to prototype to actual deployment.

Dark fiber refers to fiber-optic cables that are currently lying unused. "With the dot-com bust, this fiber became available at fire-sale prices," says Steve Cotter, department head for ESNet. Though the price of dark fiber had risen again in recent years, Cotter says, the economic downturn has made it cheap again. ESNet and Internet2 took the opportunity to lease fiber for the next 20 years.

For the 100-gigabit-per-second network, ESNet and Internet2 added equipment and software to allow the network to function. The experimental test bed, however, which is a separate network, gets left dark—open to whatever equipment or protocols researchers want to bring to it.

As an example, Cotter says, it's well known that the current protocols for transferring information over the Internet, such as TCP/IP, are creaking with age. The decades-old protocols break down in very-high-bandwidth situations in particular. Cotter expects researchers to test new alternatives.

The dark-fiber test bed provides a way to test new hardware, such as devices like optical routers, which combine optical and electronic components. It could also be useful for security researchers. "It's very hard to do 'deep-packet inspection' at 100 Gbps," says Cotter, referring to a technique typically used to check for malicious network traffic. He adds that it's important to anticipate what could happen if spammers or malicious hackers got access to very high bandwidth, and develop ways to defend against that.

Cotter also believes the new networks "open up a whole new area of research" into the power efficiency of network devices. He wants to collect data on real-time power consumption and correlate it with traffic patterns to see when the network itself is becoming an energy guzzler. Data centers have received a lot of attention for the energy they consume, Cotter says, but the energy used to move data around the world is also important.

Lachlan Andrew, an ARC Future Fellow at the Centre for Advanced Internet Architectures at Swinburne University of Technology, says the 100-gigabit-per-second network "will be very useful for people testing end-to-end 'application layer' protocols." That network won't do much for researchers who want to investigate the deep structure of the network or the hardware used to operate it, but it will be good for those who want to test software in high-bandwidth conditions, Andrew says.

The dark-fiber network, on the other hand, lets researchers investigate networks at any level they want. However, it requires researchers to install their own equipment at many points inside the network to "light up the fiber." Andrew says that's a great opportunity for electrical engineers working on networking hardware, but might be an expensive prospect for others.

The new networks "will provide an environment that is realistic, truly state-of-the-art, and flexible for experimentation," says Steven Low, a professor of computer science and electrical engineering at Caltech who researches network architecture. "Such an environment will be critical for cutting-edge applied networking research."

Vietzke says construction of both the 100-gigabit-per-second network and the dark-fiber research test bed are well underway. The first stage will be completed by the end of the year. The next stage, which will extend the network to new locations, will be completed within a year.

It's not clear exactly what will come out of access to the networks, and Vietzke says that's half the point. "I don't think you could have imagined that the bandwidth-rich environment [typically available at universities and research centers] could have transformed global politics, commerce, and economics as much as it has in recent years," he says. He points not only to scientific advances but to dorm-room inventions such as Facebook and Napster. There's every reason, he says, to expect the next generation of the Internet to be just as disruptive.

Communications: Would an iPhone 'Assistant' Really Help?

Communications: Would an iPhone 'Assistant' Really Help?

Apple may be building the technology into iOS. But can it succeed where others have failed?

Are we on the cusp of an era of ubiquitous "virtual personal assistants"? If Steve Jobs has his way, we just might be.

Back in the spring of 2010, Apple acquired Siri, a company that produced an app that described itself in just those terms. Now, clues dug up recently by 9to5Mac, a site dedicated to scrutinizing all things Apple, suggest that Apple may be ready to introduce Siri-like features in the next version of iOS, its operating system for the iPhone, iPod touch, and iPad.

If Apple is indeed about to launch a personal assistant, it could help set the iPhone apart from other smart phones in the market. Android's voice-command system is considered one of its chief advantages over the iPhone, but a Siri-derived personal assistant would add more voice functionality, eliminating Android's advantage. But it will be a gamble, as other efforts to foist a personal assistant upon computer users have backfired badly. Remember Clippy, the animated paper clip that would pop up every time you tried to write a letter in Microsoft Word?

In a screenshot that 9to5Mac turned up, apparently from the menu on an iPhone "test unit," one button reads "Assistant"; another reads "Speaker," suggesting that the assistant can talk back, if you want it to; and a tab reading "MyInfo" suggests that the assistant will be able to use data on your phone such as address book contacts and location to help find the information you want. 9to5Mac further claims to have plumbed the depths of an iOS software development kit and found lines of code that correspond to the features in the screenshot.

Siri's original app, which licensed voice recognition technology from Nuance, a company based in Burlington, Massachusetts, enabled users to perform searches and make appointments or reservations using voice commands. It worked remarkably well for these simple tasks. (You can see a video of it in action here.)

Work on Siri began about eight years ago, when DARPA funded a massive AI initiative called CALO (Cognitive Assistant that Learns and Organizes). The idea, says Norman Winarsky, vice president of ventures at SRI, based in Menlo Park, California, the prime contractor for CALO, was to develop a virtual personal assistant as good as the character of Radar O'Reilly on the TV show M*A*S*H. "Radar always knew what the captain wanted before the captain knew what the captain wanted," says Winarsky.

As the CALO program wound down, SRI recognized a massive market opportunity in the research it had been doing. Over a period of a few years, SRI built the company Siri and launched an app.

Apple scooped up the company less than three months after the Siri app launched. Since then, we've all been held in suspense. Once Apple acquires a company, says Winarsky, "they go into radio silence, and believe me, they don't share with SRI or anybody" as to just what their plans are.

But, even if Apple is ready to offer a virtual personal assistant to every iPhone 5 buyer, does that mean every iPhone 5 buyer is ready for a virtual personal assistant? Not if it doesn't at least outperform Clippy.

Jason Hong, an associate professor at Carnegie Mellon University and a member of its Human-Computer Interaction Institute, says Microsoft Word's Clippy failed for two reasons: he was intrusive, interrupting you when you had already begun a task, and he simply wasn't very smart, often failing to understand your intentions, when you bothered to indulge him, that is. Hong found an explanation at a talk given by Eric Horvitz, the Microsoft researcher who worked on some of the AI behind Clippy. "They had to lobotomize all the machine learning they used, to make it primitive enough to run fast and in real time" on your desktop, says Hong.

Now, though, smart phones are blisteringly fast, and complex processing can be outsourced to the cloud, which means we can fully leverage the fruits of AI research even from relatively simple hardware. What's more, adds Hong, Siri is crucially "driven by what the user is explicitly asking"—it doesn't pop up officiously, like that insufferable paper clip.

Winarsky is betting that virtual personal assistants will be ubiquitous, and widely accepted, sooner than many expect. Looking beyond the restaurant reservations that Siri handled so well, Winarsky foresees an era when virtual personal assistants offer advice and recommendations on a range of topics. Eventually, he says, the technology will be folded into the desktop and the Web, and it will make people rich. "Within 10 years," he says, "we will see the value associated with virtual personal assistants throughout our marketplace to be in the many tens of billions—and [it] optimally might reach the 100-billion-dollar level."

The biggest stumbling block ahead might just be how willing people are to be heard constantly issuing commands in carefully enunciated English into their iPhones. "I used to play a game of guessing whether people I saw talking to themselves were drunk, crazy, or on the phone," says Hong. "And sometimes it was pretty hard to tell."

In that sense, the most important feature visible on the leaked 9to5Mac screenshot may well be the button labeled "OFF."

Communications: Ultrafine Location Fixes

Posted by echa 4:04 PM, under | No comments

Small ground-based transmitters that mimic GPS satellites help receivers find their position with high accuracy.

The GPS technology that allows cell phones and other devices to pinpoint their location to within a few meters has made possible new services ranging from location-aware social networks to self-driving cars. A new location technology accurate to a few centimeters will refine those services and unlock another wave of novel ideas, claims Australian company Locata. The company's technology can work alongside GPS to provide superaccurate positioning or fill in the gaps in places where GPS signals are blocked.

Locata's technology involves installing a network of "LocataLites"--devices about the size of a hardback book--in several known locations across an area. These devices function like grounded versions of GPS satellites, sending out signals that receivers use to get a location fix. LocataLites transmit signals using the same frequency as Wi-Fi, and they can each cover several kilometers. "We introduce a local constellation that works like the one in space," says Nunzio Gambale, one of Locata's two cofounders. "It's just much cheaper and more accurate."

The technology will be used to track aircraft on the U.S. Air Force's White Sands Missile Range in New Mexico, where an upgraded system will soon cover an area of 6,474 square kilometers. The Boddington gold mine in Western Australia is using Locata's technology to position digging and drilling equipment with high accuracy. It is a convenient alternative to manually surveying the insides of the deep opencast mine, the walls of which block GPS signals. The same effect often weakens or blocks GPS signals in urban environments. Locata's technology is also attractive for any city wanting to offer its own "location hotspot" to fix that, says Gambale.

Next month, Locata will release information that will allow other companies to manufacture receivers, a move intended to see the technology added to devices that already use GPS signals. "It's like the early days of GPS," says Gambale. "The real explosion will happen when there are chip-scale receivers that can fit into your pocket."

Ultimately, this could mean smart phones that know their location with remarkable accuracy, enabling apps such as augmented reality to be much more powerful. Before that, however, construction sites, warehouses, and factories will likely benefit. Tracking goods and machines with high accuracy can enable greater use of robotics and automation, says Gambale.

Locata's technology was enabled by a cheaper alternative to the atomic clock found inside every GPS satellite. Each satellite uses its clock to timestamp the signal it sends back to Earth. A receiver can use that timestamp to calculate its distance from a satellite, based on the time it took for the signal to travel. Repeating this trick with several satellites reveals a gadget's position through triangulation.

Locata's satellite mimics are built with timing chips much less accurate than an atomic clock. That's possible because they only keep in sync with one another, not to an external standard, says Gambale. LocataLites do this by listening to each other's signals. Each LocataLite adjusts the timing of its outgoing signal based on the timing of the signals it picks up from other LocataLites, creating a feedback loop that ensures all the signals are in sync. "All the clocks drift together," says Gambale, and all the signals are synchronized to within two nanoseconds.

"Synchronizing this kind of device is a big research task," says Per Enge, professor and leader of the GPS research lab at Stanford University. His group is working on similar devices known as pseudolites that will be deployed across the U.S. by the Federal Aviation Authority to boost the reliability of GPS and to protect signals against jamming or natural interference. The goal is to make it possible for civilian aircraft to rely on GPS more heavily so they can use more sophisticated autopilots that help cut fuel use.

Enge says it is likely that these pseudolites will rely on time signals sent over the Internet, using a new protocol that enables high accuracy. Some may tune in to time signals broadcast by Iridium communications satellites, which are in lower orbits than GPS satellites and so yield stronger signals back on Earth.

Locata's approach of using feedback among its devices sounds "valid," Enge says, although those at the edge of a network might be more likely to lose their timing if they cannot correlate with as many of their fellows as those nearer the center.

Gambale hopes Locata's technology could also aid aviation, and he says he has conducted test flights in Australia using the technology. However, civil aviation adopts new technology very cautiously due to the need for absolute safety. "Locata will make their money from construction and agriculture," says Enge.

Communications: New Tool Keeps Censors in the Dark

Communications: New Tool Keeps Censors in the Dark 

Anti-censorship software would make it harder for censors to track—and block—undesirable communications.

A new approach to overcoming state-level Internet censorship relies, ironically enough, on a technique that security experts have frequently associated with government surveillance.

Current anti-censorship technologies, including the services Tor and Dynaweb, direct connections to restricted websites through a network of encrypted proxy servers, with the aim of hiding who's visiting such sites from censors. But the censors are constantly searching for and blocking these proxies. A new scheme, called Telex, makes it harder for censors to block communications by disguising traffic destined for restricted sites as traffic meant for popular, uncensored websites. It does this by employing the same method of analyzing packets of data that censors often use.

"To route around state-level Internet censorship, people have relied on proxy servers outside of the country doing the censorship," says J. Alex Halderman, assistant professor of electrical engineering and computer science at the University of Michigan. "The difficulty there is, you have to communicate to those people where the proxies are, and it's very hard to do that without also letting the government censors figure out where the proxies are."

The Telex system has two major components: "stations" at dozens of Internet service providers (ISPs)—the stations connect traffic from inside nations that censor to the rest of the Internet—and the Telex client software program that runs on the computers of people who want to avoid censorship.

To disguise the destination of the traffic the user wants to send, Telex employs a form of cryptography called "steganography," which is the practice of hiding secret messages within readable messages.

The Telex client software starts by making an outgoing connection to a nonblocked website, encrypting the traffic in the same way that an e-commerce or online banking site does (the address in the browser bar begins with https:// instead of http://). The identity of the censored site is then encoded in a special string, or "tag," that's embedded in the encrypted request. A Telex station at an ISP can examine incoming traffic and detect the presence of these tags, providing it has the right encryption key. The tag would be indistinguishable from random gibberish without the key.

When the Telex station detects an incoming request that includes a tag, it redirects that connection to the site specified in the encrypted message. This behavior resembles a controversial technology called "deep packet inspection" (DPI), which governments and ISPs have used for censorship and for blocking or throttling certain types of Internet traffic, such as peer-to-peer file-sharing.

"DPI has been used notoriously as a means of censorship, but Telex uses DPI in a completely different way," Halderman says. "We're basically turning the concept on its head to create something that's a really powerful anti-censorship tool."

Halderman says the design is such that it doesn't matter if the location of ISPs employing Telex stations are known to the censors. "The key thing is that we want to put the stations at enough points in the Internet so that blocking all the routes that go through those would be tantamount to making the Internet unavailable," he says. "The vision is that if we deploy Telex widely enough, it can make connecting to the Internet for a government that might want to do censorship an all-or-nothing proposition. Either you live with the fact that people can get to sites you want to censor, or you effectively pull the plug entirely."

In a paper on Telex submitted to the Usenix Security Symposium this month, Halderman and others describe in detail how their system would resist attacks by censors.

"We've gotten a lot of comment from people who don't understand the system, who are pointing out ways they believe the system could be defeated, but in almost every case, it's something we've thought about and addressed in the paper," he says, adding that the system was designed to adapt to increasingly sophisticated censorship methods.

"Censored users today have moderate success using normal proxy servers, but what we're seeing is that major countries involved in censorship are adapting quite quickly to that," Halderman says. "For example, China has gotten very effective in blocking Tor, and Iran has also made some quite sophisticated countermeasures against Tor."

Bruce Schneier, a cryptography expert and chief security technology officer at BT, calls Telex "well thought-out and designed," but says the system would not work without widespread adoption by ISPs around the world.

"There are two ways to deploy this system: ask nicely, or make it a law [for ISPs to implement it]," Schneier says. "It would be great if the governments of the world backed this idea, because in general this sort of thing is why you don't see these technologies widely adopted. No one is willing to pay for them, and no one is going to support them otherwise."

The researchers are working to expand a test Telex network that they've been using for months to surf the Web, and even to watch YouTube videos. They note that the test system works with "acceptable stability and little noticeable performance degradation," and that it performed well in the face of some unexpected stress testing. A researcher accidentally misconfigured one of the Telex stations to act as an open Internet proxy; it wasn't long before the system was being used by outsiders hoping to hide their identities.
