LA Microsoft Store not mobbed, but Surface has a following

The Surface Pro

LOS ANGELES -- The launch of the Surface Pro at the Microsoft Store in LA's Century City was a relatively low-key affair compared with the debut of the Surface RT.

When I arrived just after 10 a.m. there was a small line (see photo). That said, both versions -- 64GB and 128GB -- of the
Surface Pro had sold out immediately.

Of course, no one would say how many units were set aside for first-day sales, and the lines didn't exactly snake around the Westfield Century City mall. So, it wasn't like a Depression-era run on a bank.

And back in October the lines were longer and the atmosphere a bit more frenzied when the Surface RT launched.

On Saturday, there was a small line outside the Century City Microsoft Store near Beverly Hills. The Surface Pro sold out immediately at the store.

But like the RT rollout, there was a fixation on and interest in the product not unlike what's found at an Apple event. I saw more than a few customers glued to the device for 30 minutes or even an hour.

In other words, Surface has a following. An analogy I would use is the Chevy Volt. Recently in LA, the Chevy Volt is gaining ground, driven by a small but growing (and fervent) customer base.

And Microsoft Store sales reps know what they're talking about. A patient, focused rep gave me a long, hands-on explanation of the
Windows 8 touch interface and demonstrated a new touch-enabled paint app, among other apps.

Finally, note that there are other enticing touch-screen Windows 8 devices at the store, including the 2.3-pound Acer Aspire S7 and the HP Spectre XT TouchSmart. And that's good for Windows 8 overall.

The Surface Pro isn't the only cool Windows 8 device on sale at the Microsoft Store. The 11.6-inch Acer Aspire S7 touch-screen laptop is a tempting alternative to the Pro.

Mars Rover Curiosity Completes First Full Drill

For the first time in history, humans have drilled a hole into rock on Mars and are collecting the powdered results for analysis, NASA announced Saturday.

After weeks of intensive planning, the Mars rover Curiosity undertook its first full drill on Friday, with NASA receiving images on Saturday showing that the procedure was a success.

Curiosity drilled a hole that is a modest 2.5 inches (6.35 centimeters) deep and .6 inches (1.52 centimeters) wide but that holds the promise of potentially great discoveries. (Watch video of the Mars rover Curiosity.)

"The most advanced planetary robot ever designed now is a fully operating analytical laboratory on Mars," John Grunsfeld, NASA associate administrator for the agency's Science Mission Directorate, said in a statement on Saturday.

"This is the biggest milestone accomplishment for the Curiosity team since the sky-crane landing last August."

The site of the much-anticipated penetration is a flat section of Mars rock that shows signs of having been underwater in its past.

Called Yellowknife Bay, it's the kind of environment where organic materials—the building block of life—might have been deposited and preserved long ago, at a time when Mars was far wetter and warmer than it is today.

The contents of the drilling are now being transferred into the rover's internal collection system, where the samples will be sieved down to size and scoured to minimize the presence of contamination from Earth. (Watch video of Curiosity's "Seven Minutes of Terror.")

Then the sample will be distributed to the two instruments most capable of determining what the rocks contain.

The first is the Sample Analysis on Mars (SAM), which has two ovens that can heat the powdered rock to almost 2000°F (1093°C) and release the rock's elements and compounds in a gaseous form.

The gases will then be analyzed by instruments that can identify precisely what they are, and when they might have been deposited. Scientists are looking for carbon-based organics believed to be essential for any potentially past life on Mars.

Powder will also go to the Chemistry and Mineralogy (CheMin) instrument for a related analysis that looks especially at the presence of minerals—especially those that can only be formed in the presence of water.

Louise Jandura, chief engineer for Curiosity's sample system at NASA's Jet Propulsion Laboratory, said that designing and testing a drill that can grab hold of Martian rock and commence first a percussive shallow drilling and then dig a deeper hole was difficult.

The drill, which is at the end of a 7-foot arm, is capable of about 100 discrete maneuvers.

"To get to the point of making this hole in a rock on Mars, we made eight drills and bored more than 1,200 holes in 20 types of rock on Earth," Jandura said in a statement.

Results from the SAM and CheMin analyses are not expected for several days to weeks.

After Blizzard, Northeast Begins to Dig Out

The Northeast began the arduous process of cleaning up after a fierce storm swept through the region leaving behind up to three feet of snow in some areas.

By early this morning, 650,000 homes and businesses were without power and at least five deaths were being blamed on the storm: three in Canada, one in New York and one in Connecticut, The Associated Press reported.

The storm dumped snow from New Jersey to Maine, affecting more than 25 million people, with more than two feet falling in areas of Massachusetts, Rhode Island and New Hampshire. The Postal Service closed post offices and suspended mail delivery today in New England.

As the storm waned, officials in the hardest hit areas cautioned residents to remain indoors and off the roads to ease the clean-up.

Massachusetts was hard hit by the storm, with more than two feet of snow in Boston and even more in coastal areas. State police and national guard troops helped rescue more than 50 stranded motorists and even helped deliver a baby girl, according to Massachusetts Gov. Deval Patrick.

Patrick enacted the first statewide driving ban since the 1978 blizzard, which left 27 inches of snow and killed dozens. The ban was to be lifted at 4 p.m. today, the governor said.

However, Patrick cautioned residents to act with extreme caution even after the ban is over.

"Stay inside and be patient," Patrick said.

In Massachusetts a boy reportedly died of carbon monoxide poisoning as he helped his father shovel snow on Saturday, according to ABCNews.com affiliate WCVB-TV in Boston.

For residents along the coast, the waning snowfall didn't mean the end of the storm. Storm surges along the Massachusetts coastline forced some residents out of their homes Saturday morning.

"We've got 20-foot waves crashing and flooding some homes," Bob Connors on Plum Island told WCVB. "We have power and heat and all that. We just have a very angry ocean. In my 33 years, I've never seen the seas this high."

In Connecticut, Gov. Dannel Malloy declared a state of emergency and closed all roads in the state. The state police responded to more than 1,600 calls over the last 24 hours and the governor called up an additional 270 National Guard members.

"If you're not an emergency personnel that's required to be somewhere, stay home," Malloy said.

Overnight, snow fell at a rate of up to five to six inches per hour in parts of Connecticut. In Milford, more than 38 inches of snow had fallen by this morning.

In Fairfield, Conn. firefighters and police officers on the day shift were unable to make it to work, so the overnight shift remained on duty.

The wind and snow started affecting the region during the Friday night commute.

In Cumberland, Maine, the conditions led to a 19-car pile-up and in New York, hundreds of commuters were stranded on the snowy Long Island Expressway. Police and firefighters were still working to free motorists early this morning.

"The biggest problem that we're having is that people are not staying on the main portion or the middle section of the roadway and veering to the shoulders, which are not plowed," said Lt. Daniel Meyer from the Suffolk County Police Highway Patrol.

In New York, authorities are digging out hundreds of cars that got stuck overnight on the Long Island Expressway.

Bob Griffith of Syosset, N.Y., said he tried leave early to escape the storm, but instead ended up stuck in the snow by the side of the road.

"I tried to play it smart in that I started early in the day, when it was raining," said Griffith. "But the weather beat us to the punch."

Suffolk County Executive Steven Bellone said the snow had wreaked havoc on the roadways.

"I saw state plows stuck on the side of the road. I've never seen anything like this before," Bellone said.

However, some New York residents, who survived the wrath of Hurricane Sandy, were rattled by having to face another large and potentially dangerous storm system with hurricane force winds and flooding.

"How many storms of the century can you have in six months?" said Larry Racioppo, a resident of the hard hit Rockaway neighborhood in Queens, New York.

In New York, a little more than 11 inches fell in the city.

By this morning, New York Mayor Michael Bloomberg said nearly all of the primary roads had been plowed and the department of sanitation anticipated that all roads would be plowed by the end of the day.

"It looks like we dodged a bullet, but keep in mind winter is not over," said Bloomberg.

Data-wiping algorithm cleans your cellphone

Paul Marks, chief technology correspondent

Mailing your cellphone to a recycling company might make you a few pounds, but it can leave you at risk of identity theft. The deletion techniques recycling companies use are meant for hard discs, and so don't work on the solid-state flash memory used in mobile phones. That means personal data like banking info, texts, contacts and pictures can end up in the hands of, well, anyone the phone ends up with.  

To remedy the problem, British company BlackBelt Smartphone Defence of Skelmersdale, Lancashire claims to have developed a software algorithm that can securely delete data on cellphone memory chips. The trouble with data in a flash memory chip is that it is protected by an on-chip protection algorithm called the wear leveller. This hard-coded routine does its best to ensure the chip's lifetime is maximised so that each memory cell's ability to store charge is not worn out.

"The problem is that the wear-levelling algorithm ends up working
against the data wiping technique used for hard drives, which tries to
overwrite all the data,"
says the company's Ken Garner.

What the firm has done is write their own algorithm, called BlackBelt DataWipe, that works with,
rather than against, the leveller routine to render data
irrecoverable. "It is like having a shredder for personally identifiable
data," says Garner.

However, they don't yet know if their method is proof against sophisticated, nation-state level attacks - which might use electron microscopes
to read the last vestiges of the zeros and ones on a memory chip. "I imagine
if you're GCHQ you'll probably have technology that could get around
this and recover it in some way," says Garner.

Venezuela devalues currency 32% against US dollar

CARACAS: Venezuela said Friday it is devaluing its currency by 32 per cent against the dollar on the orders of cancer-stricken President Hugo Chavez, in part to trim a bloated budget deficit.

The bolivar will go from 4.3 to 6.3 to the dollar at the official exchange rate. The move was announced at a press conference by Planning and Finance Minister Jorge Giordani. He said it will take effect on Wednesday.

The goal is to "minimize expenditure and maximize results." One effect of a devaluation is to make a country's exports cheaper and thus more enticing to buyers.

But another effect is to cut the deficit, which in Venezuela last year was estimated to be nearly 10 per cent of GDP.

The economy grew 5.5 per cent last year and inflation was 20 per cent. That was down seven points from the previous year and hit the government target, but was still the highest official inflation rate in Latin America.

Venezuela is South America's largest oil exporter and has the world's largest proven reserves. Its oil transactions are dollar-denominated, so the bolivar-value of those sales will now be higher, boosting state revenues on paper.

The change had been widely expected by analysts and business leaders since last year. This is Venezuela's fifth currency devaluation in a decade.

But a side effect of the new one will be higher inflation, economists warned.

Giordani said the government would honour dollar purchase requests made before January 15 requests at the old exchange rate.

Chavez is convalescing in Cuba, where he underwent a fourth round of cancer surgery on December 11.

Vice President Nicolas Maduro, who visited Chavez this week, said at the same press conference Friday that Chavez is concerned about the Venezuelan economy and called for a "major effort" to maintain its pace of growth.

Chavez established currency controls in 2003 and the government sets the rate to curb capital flight.

But the existence of a strong black market for the dollar shows the continuing desire for hard currency.

Economist Jesus Casique warned the devaluation would have a major inflationary side effect and the government should not see it as the main tool for trimming the deficit.

Rather, it should take other steps such as clearing away red tape that makes it hard for business to obtain dollars and encouraging Venezuelan non-oil exports.

"The measure should come hand in hand with others," Casique said.

Out on the street, there was little enthusiasm for the devaluation.

"This is bad news," said businessman Jorge Martinez, walking past the Venezuelan central bank with his wife. "We have been number-crunching because in a month we are going to travel to Spain, and now we do not have enough money."

Yelp CEO takes $1 salary

Add Jeremy Stoppelman, chief executive of business reviews site Yelp, to the list of CEOs who are willing to work for $1.

Stoppelman will take a $1 base salary for 2013, according to information in Yelp's 8-K document filed today with the Securities and Exchange Commission. The itsy-bitsy take-home pay makes Stoppelman just like Steve Jobs and Mark Zuckerberg, who have also preferred to work for just a buck.

Both Stoppelman and Chief Operating Officer Geoff Donaker reduced their base salaries to $1 for 2013. Stoppelman's 2012 salary was $300,000, according to public documents. The Yelp CEO made $220,000 in 2009, 2010, and 2011.

Of course, Stoppelman isn't working for free. Far from it. The chief executive's real payment for 2013 consists of 665,000 options that will vest at different rates.

One twenty-fourth of the 90,000 options Stoppelman was granted will vest each month for the next two years, which works out to be a relatively generous vesting schedule. When all 90,000 of those shares vest in 2 years, they'll be worth around $2 million, should Yelp's stock price remain stable.

Yelp's value, however, is a huge variable as share prices have bounced around between $14 and $32 a share since the company's initial public offering 11 months ago. Just this week, the reviews business bummed out investors when it reported a net loss of $5.3 million for the fourth quarter. Yelp's share price took an instant hit but recovered to close today at $21.85 a share.

  Most of the electrically charged gas, imaged in extreme ultraviolet light, was unsuccessful in its escape attempt and fell back into the sun.

  Filaments form when magnetic field lines push out of the sun in loops, holding dense gas above the surface of the sun. (Read about a huge solar filament that erupted in August 2012.)

'Stay Home': Northeast Shuts Down as Blizzard Hits

A blizzard of possibly historic proportions began battering the Northeast today, and could bring more than two feet of snow and strong winds that could shut down densely populated cities such as Boston and New York City.

A storm from the west joined forces with one from the south to form a nor'easter that will sit and spin just off the East Coast, affecting more than 43 million Americans. Wind gusts were forecast to reach 50 to 60 mph from Philadelphia to Boston.

Cape Cod, Mass., could possibly see 75 mph gusts. Boston and other parts of New England could see more than two feet of snow by Saturday.

The storm showed the potential for such ferocity that Massachusetts Gov. Deval Patrick declared a state of emergency Friday afternoon and signed an executive order banning vehicular traffic on roads in his state effective at 4 p.m. ET. It was believed that the last time the state enacted such a ban was during the blizzard of 1978. Violating the ban could result in a penalty of up to a year in jail and a $500 fine.

"[It] could definitely be a historic winter storm for the Northeast," said Adrienne Leptich of the National Weather Service in Upton, N.Y. "We're looking at very strong wind and heavy snow and we're also looking for some coastal flooding."

Airlines began shutting down operations Friday afternoon at major airports in the New York area as well as in Boston, Portland, Maine, Providence, R.I., and other Northeastern airports. By early evening Friday, more than 4,300 flights had been cancelled on Friday and Saturday, according to FlightAware. Airlines hoped to resume flights by Saturday afternoon, though normal schedules were not expected until Sunday.

The snow fell heavily Friday afternoon in New York City and 12 to 14 inches were expected. Mayor Michael Bloomberg said clearing the roads was his main concern, and the city readied 1,700 snow plows and 250,000 tons of salt to clear the streets.

New York City was expecting up to 14 inches of snow, which started falling early this morning, though the heaviest amounts were expected to fall at night and into Saturday. Wind gusts of 55 mph were expected in New York City.

"Stay off the city streets. Stay out of your cars and stay at home while the worst of the storm is on us," Bloomberg said Friday.

Connecticut Gov. Dannel P. Malloy declared a state of emergency, deploying National Guard troops across the state to assist in rescues and other emergencies. Schools and state courthouses were closed, and all flights after 1:30 p.m. at Bradley Airport, north of Hartford, Conn., were cancelled. The state's largest utility companies planned for the possibility that 30 percent of customers -- more than 400,000 homes and businesses -- would lose power.

Malloy also directed drivers to stay off the state's major highways.

"Please stay off of 95, 91, 84, Merritt Parkway and any other limited-access road in the state," he said Friday evening.

PHOTOS: Northeast Braces for Snowstorm

Boston, Providence, R.I., Hartford, Conn., and other New England cities canceled school today.

"Stay off the streets of our city. Basically, stay home," Boston Mayor Tom Menino warned Thursday.

On Friday, Menino applauded the public's response.

"I'm very pleased with the compliance with the snow emergency," he said. "You drive down some of the roadways, you don't see one car."

As of 4:30 p.m. Friday, according to the Department of Defense, 837 National Guard soldiers and airmen under state control had been activated in Connecticut, Massachusetts and New York in anticipation of the storm -- 552 in Massachusetts, 235 in Connecticut and 50 in New York. The extra hands were helping with roadways, transportation, making wellness checks on residents and other emergency services.

Beach erosion and coastal flooding is possible from New Jersey to Long Island, N.Y., and into New England coastal areas. Some waves off the coast could reach more than 20 feet.

Blizzard warnings were posted for parts of New Jersey and New York's Long Island, as well as portions of Massachusetts, Rhode Island and Connecticut, including Hartford, New Haven, Conn., and Providence. The warnings extended into New Hampshire and Maine.

To the south, Philadelphia was looking at a possible 4 to 6 inches of snow.

In anticipation of the storm, Amtrak said its Northeast trains would stop running this afternoon.

Robot inquisition keeps witnesses on the right track

MEMORY is a strange thing. Just using the verb "smash" in a question about a car crash instead of "bump" or "hit" causes witnesses to remember higher speeds and more serious damage. Known as the misinformation effect, it is a serious problem for police trying to gather accurate accounts of a potential crime. There's a way around it, however: get a robot to ask the questions.

Cindy Bethel at Mississippi State University in Starkville and her team showed 100 "witnesses" a slide show in which a man steals money and a calculator from a drawer, under the pretext of fixing a chair. The witnesses were then split into four groups and asked about what they had seen, either by a person or by a small NAO robot, controlled in a Wizard of Oz set-up by an unseen human.

Two groups - one with a human and one a robot interviewer - were asked identical questions that introduced false information about the crime, mentioning objects that were not in the scene, then asking about them later. When posed by humans, the questions caused the witnesses' recall accuracy to drop by 40 per cent - compared with those that did not receive misinformation - as they remembered objects that were never there. But misinformation presented by the NAO robot didn't have an effect.

"It was a very big surprise," says Bethel. "They just were not affected by what the robot was saying. The scripts were identical. We even told the human interviewers to be as robotic as possible." The results will be presented at the Human-Robot Interaction conference in Tokyo next month.

Bilge Mutlu, director of the Human-Computer Interaction Laboratory at the University of Wisconsin-Madison, suggests that robots may avoid triggering the misinformation effect simply because we are not familiar with them and so do not pick up on behavioural cues, which we do with people. "We have good, strong mental models of humans, but we don't have good models of robots," he says.

The misinformation effect doesn't only effect adults; children are particularly susceptible, explains the psychologist on the project, Deborah Eakin. Bethel's ultimate goal is to use robots to help gather testimony from children, who tend to pick up on cues contained in questions. "It's a huge problem," Bethel says.

At the Starkville Police Department, a 10-minute drive from the university, officers want to use such a robotic interviewer to gather more reliable evidence from witnesses. The police work hard to avoid triggering the misinformation effect, says officer Mark Ballard, but even an investigator with the best intentions can let biases slip into the questions they ask a witness.

Children must usually be taken to a certified forensic child psychologist to be interviewed, something which can be difficult if the interviewer works in another jurisdiction. "You might eliminate that if you've got a robot that's certified for forensics investigations, and it's tough to argue that the robot brings any memories or theories with it from its background," says Ballard.

The study is "very interesting, very intriguing", says Selma Sabanovic, a roboticist at Indiana University. She is interested to see what happens as Bethel repeats the experiment with different robot shapes and sizes. She also poses a slightly darker question: "How would you design a robot to elicit the kind of information you want?"

This article appeared in print under the headline "The robot inquisition"

It's all about how you say it

When providing new information, rather than helping people recall events (see main story), a robot's rhetoric and body language can make a big difference to how well it gets its message across.

Bilge Mutlu of the University of Wisconsin-Madison had two robots compete to guide humans through a virtual city. He found that the robot which used rhetorical language drew more people to follow it. For example, the robot saying "this zoo will teach you about different parts of the world" did less well than one saying "visiting this zoo feels like travelling the world, without buying a plane ticket". The work will be presented at the Human-Robot Interaction conference in Tokyo next month.

Tennis: No Serena, no Sharapova in tweaked Fed Cup

PARIS: The 2013 Fed Cup World Group gets underway on Saturday with the tournament missing marquee names Serena Williams and Maria Sharapova and with a late format tweak aimed at boosting the event's appeal.

Both Williams and Sharapova featured in the 2012 Fed Cup, partly to meet Olympic Games qualifying criteria, but will not be involved when the United States tackle Italy and Russia welcome Japan this weekend.

Williams, who has played just six ties since 1999, has a back injury while Sharapova, whose Fed Cup record stretches to a meagre three appearances since her 2008 debut, was left out of the Russian squad.

Their absences have cut the number of players from the top 10 competing in the four World Group One ties to just three -- number seven Sara Errani of Italy, eighth-ranked Petra Kvitova of the Czech Republic and number nine Samantha Stosur of Australia.

Wary of the growing demands placed on time and physical endurance by the professional tour, the International Tennis Federation (ITF) announced on Thursday changes concerning dead rubbers in the tournament.

Under the new policy, if a tie is decided after the third singles rubber, the fourth singles rubber will not be played and the dead doubles rubber will be played instead.

However if the tie is only decided after the fourth singles rubber, the dead doubles rubber will still be played with a match tiebreak (first to 10 points) replacing the third set.

"The enhancement of the dead rubber policy came in response to requests from players, captains and National Associations following its successful introduction in Davis Cup," said ITF executive vice-president Juan Margets.

"This is part of the ITF's continued effort to make Fed Cup more player friendly, while maintaining a good spectator experience on the Sunday."

Former Wimbledon champion Kvitova leads defending champions Czech Republic against Australia in Ostrava where she will be playing her 14th Fed Cup tie since 2007.

However, she has struggled this season, a shock second round exit at the Australian Open followed by a quarter-final loss in Paris last week where she was second seed.

"My results are not exactly what I want them to be, but I still believe it will be OK. I know I can play tennis, and I like Fed Cup," said the 22-year-old.

In the absence of the Williams sisters, as well as Australian Open semi-finalist Sloane Stephens, the 17-time champions US will be led by world number 21 Varvara Lepchencko when they face Italy in Rimini.

Italy, with Errani and world number 16 Roberta Vinci likely to play singles and doubles, beat the US in the 2009 and 2010 finals.

Even without Sharapova, Russia, the four-time winners, should be too strong for Japan in Moscow.

Maria Kirilenko, at 13, Ekaterina Makarova, the world number 20, Anastasia Pavlyuchenkova, the 31st-ranked player and number 32 Elena Vesnina, are all higher up the WTA pecking order than Japan's top singles player Ayumi Morita, the world 57.

In Nis, 2012 runners-up Serbia, who are likely to be without world number 14 and former French Open champion Ana Ivanovic with a shoulder injury, tackle Slovakia.
