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.

Blizzard brings US northeast to a halt

NEW YORK: Planes, cars and trains came to a standstill across the densely populated US northeast Friday in the face of a blizzard raging from New York to Boston.

The storm was forecast to bring the heaviest snow so far this winter along the New England coast, threatening power and transport links for tens of millions of people.

By late Friday, New York, one of the world's busiest air travel hubs, was cut off from the skies as snow and wind led airlines to suspend all operations at LaGuardia, Newark Liberty and John F Kennedy International airports.

Tom Bosco, general manager of LaGuardia, told NY1 television that the airport was "battling" the storm and would strive to remain open even after the airlines shut down for the night.

He estimated that if a foot of snow fell -- the worst case scenario forecasted for New York -- flights would resume "probably by mid-morning."

The heaviest impact of the storm was expected overnight in and around Boston, and Governor Deval Patrick temporarily ordered all normal traffic off Massachusetts roads, with the threat of up to a year in jail for violators.

"There are a number of exemptions for... emergency workers and the like. Please exercise caution and use common sense," Patrick said at his emergency centre in Framingham.

In Connecticut, Governor Dannel Malloy issued a "ban on motor vehicle travel on limited access highways" to free up emergency services traffic.

Rhode Island, where some of America's most exclusive summer homes are located, also instituted driving restrictions.

In addition to the road and air snarl-ups, the rail service Amtrak said trains from New York northbound and also to the capital Washington, DC, were being suspended.

The storm came a little over three months after Hurricane Sandy devastated swathes of New York and New Jersey, killing 132 people and causing damage worth some $71.4 billion.

Snow began in light flurries across the region early Friday, but thickened and by Saturday was expected to leave depths of between half and one foot in New York and as much as two feet in Boston.

The National Weather Service warned that "in addition to the heavy snowfall, wind gusts of up to hurricane force are possible, especially near the coast. This will result in blizzard conditions with drifting and blowing snow."

On Friday night travel "will be extremely hazardous, if not impossible," the National Weather Service said.

Among the more glamorous victims of the travel upsets was designer Marc Jacobs, who said he had to reschedule his two shows at New York Fashion Week due to "the snow storm in the US and production problems."

New York Mayor Michael Bloomberg, who came under withering criticism for the city's flat-footed response to a blizzard in 2010, said residents should stock up with vital supplies and prepare for the worst.

"Stay off the city streets, stay out of your cars," he said at a news conference. "Staying off the streets will make it easier for city workers to clear the streets of snow."

New York's four zoos also announced they were closing for the duration of the storm.

"You can't take nature too lightly. Hopefully it won't be anything too drastic," Bloomberg said.

The good news was that the storm's peak was due as the weekend began, meaning far fewer people would be on the roads. Forecasters said the system should blow through on Saturday, with milder temperatures to follow.

Locals were comparing the coming storm to the ferocious Blizzard of 1978, which killed 100 people and buried Boston in more than 27 inches (68 centimetres) of snow and Providence, Rhode Island in nearly 28 inches (71 centimetres).

During that storm, people were forced to abandon cars stuck on highways and made their way around Boston on cross-country skis and snowshoes.

Dining can be a delicate thing. Finding the right balance of flavors and ingredients can be tricky, but the meal is only half the story. Surrounding whatever food is on the plate, of course, is the environment. The setting could be anything from the soft glow of a candlelight dinner to the bright glare of a midday meal. Or, it could be any number of options dialed up from the range hood. Yes, that oft-overlooked thing above the stovetop.

The color of meal-making can now be controlled with the Arkea range hood made by the European firm Faber. The striking hood makes a big first impression with its stark, spherical design. However, it's when the lights go dim that the kitchen accessory really shines. Hidden inside, there lies a series of LEDs capable of illuminating the kitchen in the lighting scheme of your choice.

From energetic red to cool violet (as well as what lies between), the kitchen hood is designed to make an impression. It's not fearful of utility, however; the range hood makes sure it can get the job done, no matter the presentation. Featuring operation via remote control, the range hood can be raised or lowered at the press of a button. In addition to its ability to vent steam and smoke away from the stovetop, the hood features four white spotlights to illuminate the actual cooking area. No matter what happens to end up on the plate, with the range hood's combination of style and functionality, it will certainly form a complete meal.

From Our Vault: Busy Postman on Break, 1951

The United States Post Office announced this week that it intends to stop Saturday letter delivery beginning in August, 32 years after Congress mandated a sixth day of mail service.

First class mail volume has been dropping by about five billion pieces annually since 2007. And the USPS operated almost $16 billion dollars in the red in 2012.

In the 1950s, when this photo was taken, the federal agency was more flush with money. Five hundred thousand employees carried 54 billion items when National Geographic magazine published the article "Everyone's Servant, the Post Office" in July of 1954. Mail volume had doubled since the previous decade, and was growing at a rate of about seven percent a year.

This photo from 1951 didn't make it into that article, landing instead in the National Geographic image archive. Working during the postal boom years, this mailman delivering to houses in Hays, Kansas, likely didn't have time to notice the slight.

National Geographic photographer John E. Fletcher explained the mailman's decision to lunch in a mailbox in a note on the back of the photo.

"He told me that a new regulation from the Washington headquarters of the U.S. Post Office required that postmen while on delivery at noontime must stop and have their lunch at the spot, rather than taking time off to go home and eat," Fletcher wrote.

"This mailman told me that each day his wife would drive to this particular corner and meet him and hand him his lunch box," he continued. "The most convenient spot that he could find to eat his lunch was to open a storage mail box, get himself comfortably seated, and eat his lunch right on the street corner."

Editor's note: This is the first in a series of pieces that looks at the news through the lens of the National Geographic photo archives.

'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.

Winter Storm to Hit Northeast With Winds and Snow Watch Video

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.

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, 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.

Microsoft wins latest round in Motorola patent case

SAN FRANCISCO: A federal judge on Thursday tossed out more than a dozen patent infringement claims filed against Microsoft by Google-owned Motorola Mobility.

US District Court Judge James Robart, in Microsoft's home state of Washington, sided with the software colossus, dismissing 13 claims of infringement on a trio of Motorola patents involving digital video encoding and decoding, according to court records.

The Motorola patents were evidently not specific enough regarding the computer code involved, according to the documents.

The decision significantly narrowed the case.

If the remaining claims survive a similar legal challenge, Microsoft would likely be entitled to pay a reasonable rate to license what is considered a "standards-essential" technology, according to intellectual property specialist Florian Mueller, of FossPatents.com.

FAA approves Boeing test flights of grounded 787 Dreamliner

Boeing was granted permission today to conduct test flights of its 787 Dreamliner as the aircraft maker tries to determine the cause of battery fires that have kept the fleet of planes grounded around the world.

The test flights will be subject to a number of restrictions, the Federal Aviation Administration said today, including limiting the flights to specific airspace over unpopulated areas. Other conditions include pre-flight testing and inspections, and in-flight monitoring.

"The traveling public's safety is our highest priority," the FAA said in a statement. "These test flights will be an important part of our efforts to ensure the safety of passengers and return these aircraft to service."

The Seattle-based aircraft builder said it hopes to resume flight test activities soon using its fifth flight test airplane, although it didn't say how many flights were planned.

"While our work to determine the cause of the recent battery incidents continues in coordination with appropriate regulatory authorities and investigation agencies, we are confident that 787 is safe to operate for this flight test activity," the company said in a statement. "As additional precautions, we have implemented additional operating practices for test flights, including a one-time preflight inspection of the batteries, monitoring of specific battery related status messages, and a recurring battery inspection."

The FAA ordered airlines to ground their fleets of the much-hyped Dreamliner last month after a series of fires involving the aircraft's lithium-ion batteries. The action came on the heels of Japanese carriers All Nippon Airways and Japan Airlines grounding their 787s after a battery fire forced the evacuation of an ANA flight.

A similar incident occurred January 7 when a JAL 787 on the ground at Boston's Logan International Airport caught fire. In response, the FAA announced it would conduct a comprehensive review of the aircraft, which features innovative use of composite materials.

The National Transportation Safety Board announced today it had traced the JAL battery fire to a single cell that short circuited and then spread to other cells. The safety board further said it will focus on the design and certification requirements of the battery system.

The NTSB said a Boeing risk assessment conducted during the plane's certification process found that the likelihood of a battery smoke emission event would occur on the 787 less than once in every 10 million flight hours.

Noting that there have already been two incidents in less than 100,000 flight hours, NTSB Chairman Deborah A.P. Hersman said in a statement that "the failure rate was higher than predicted as part of the certification process and the possibility that a short circuit in a single cell could propagate to adjacent cells and result in smoke and fire must be reconsidered."

Asteroid to Make Closest Flyby in History

Talk about too close for comfort. In a rare cosmic encounter, an asteroid will barnstorm Earth next week, missing our planet by a mere 17,200 miles (27,700 kilometers).

Designated 2012 DA14, the space rock is approximately 150 feet (45 meters) across, and astronomers are certain it will zip harmlessly past our planet on February 15—but not before making history. It will pass within the orbits of many communications satellites, making it the closest flyby on record. (Read about one of the largest asteroids to fly by Earth.)

"This is indeed a remarkably close approach for an asteroid this size," said Paul Chodas, a research scientist at NASA's Jet Propulsion Laboratory Near Earth Object (NEO) program office in Pasadena, California.

"We estimate that an asteroid of this size passes this close to the Earth only once every few decades."

The giant rock—half a football field wide—was first spotted by observers at the La Sagra Observatory in southern Spain a year ago, soon after it had just finished making a much more distant pass of the Earth at 2.6 million miles (4.3 million kilometers) away.

This time around however, on February15 at 2:24 pm EST, the asteroid will be passing uncomfortably close—ten times closer than the orbit of the moon—flying over the eastern Indian Ocean near Sumatra (map). (Watch: "Moon 101.")

Future Impact?

Chodas and his team have been keeping a close eye on the cosmic intruder, and orbital calculations of its trajectory show that there is no chance for impact.

But the researchers have not yet ruled out future chances of a collision. This is because asteroids of this size are too faint to be detected until they come quite close to the Earth, said Chodas.

"There is still a tiny chance that it might hit us on some future passage by the Earth; for example there is [a] 1-in-200,000 chance that it could hit us in the year 2080," he said.

"But even that tiny chance will probably go away within the week, as the asteroid's orbit gets tracked with greater and greater accuracy and we can eliminate that possibility."

Earth collision with an object of this size is expected to occur every 1,200 years on average, said Donald Yeomans, NEO program manager, at a NASA news conference this week.

DA14 has been getting closer and closer to Earth for quite a while—but this is the asteroid's closest approach in the past hundred years. And it probably won't get this close again for at least another century, added Yeomans.

While no Earth impact is possible next week, DA14 will pass 5,000 miles inside the ring of orbiting geosynchronous weather and communications satellites; so all eyes are watching the space rock's exact trajectory. (Learn about the history of satellites.)

"It's highly unlikely they will be threatened, but NASA is working with satellite providers, making them aware of the asteroid's pass," said Yeomans.

Packing a Punch

Experts say an impact from an object this size would have the explosive power of a few megatons of TNT, causing localized destruction—similar to what occurred in Siberia in 1908.

In what's known as the "Tunguska event," an asteroid is thought to have created an airburst explosion which flattened about 750 square miles (1,200 square kilometers) of a remote forested region in what is now northern Russia (map).

In comparison, an impact from an asteroid with a diameter of about half a mile (one kilometer) could temporarily change global climate and kill millions of people if it hit a populated area.

Timothy Spahr, director of the Minor Planet Center at Cambridge, Massachusetts, said that while small objects like DA14 could hit Earth once a millennia or so, the largest and most destructive impacts have already been catalogued.

"Objects of the size that caused the extinction of the dinosaurs have all been discovered," said Spahr. (Learn about what really happened to the dinosaurs.)

A survey of nearly 9,500 near-Earth objects half a mile (one kilometer) in diameter is nearly complete. Asteroid hunters expect to complete nearly half of a survey of asteroids several hundred feet in diameter in the coming years.

"With the existing assets we have, discovering asteroids rapidly and routinely, I continue to expect the world to be safe from impacts in the future," added Spahr.

Alleged Cop-Killer Has Calif. Region on Edge

The truck owned and driven by suspected cop killer Christopher Dorner during his alleged rampage through the Los Angeles area was found deserted and in flames on the side of Bear Mountain, Calif., this afternoon.

Heavily armed SWAT team members descended onto Bear Mountain from a helicopter manned with snipers today to investigate the fire. The San Bernadino Sheriff's Department confirmed the car was Dorner's.

Dorner, a former Los Angeles police officer and Navy reservist, is believed to have killed one police officer and injured two others early this morning in Riverside, Calif. He is also accused of killing two civilians on Sunday after releasing a scathing "manifesto" alleging grievances committed by the police department while he worked for it and warning of coming violence toward cops.

Read More About Chris Dorner's Allegations Against the LAPD

Heavily armed officers spent much of Thursday searching for signs of Dorner, investigating multiple false leads into his whereabouts and broadcasting his license plate and vehicle description across the California Highway System.

Around 3:45 p.m. ET, police responded to Bear Mountain, where two fires were reported, and set up a staging area in the parking lot of a ski resort. They did not immediately investigate the fires, but sent a small team of heavily armed officers up in the helicopter to descend down the mountain toward the fire.

The officers, carrying machine guns and searching the mountain for any sign of Dorner, eventually made it to the vehicle and identified it as belonging to Dorner. They have not yet found Dorner.

Late this afternoon, CNN announced that Dorner had sent a package containing his manifesto and a DVD to its offices.

PHOTOS: Former LAPD Officer Suspected in Shootings

Police officers across Southern California were on the defensive today, scaling back their public exposure, no longer responding to "barking-dog calls" and donning tactical gear outdoors.

Police departments have stationed officers in tactical gear outside police departments, stopped answering low-level calls and pulled motorcycle patrols off the road in order to protect officers who might be targets of Dorner's alleged rampage.

"We've made certain modifications of our deployments, our deviations today, and I want to leave it at that, and also to our responses," said Chief Sergio Diaz of the police department in Riverside, Calif., where the officers were shot. "We are concentrating on calls for service that are of a high priority, threats to public safety, we're not going to go on barking dog calls today."

Sgt. Rudy Lopez of the Los Angeles Police Department said Dorner is "believed to be armed and extremely dangerous."

Early Thursday morning, before they believe he shot at any police officers, Dorner allegedly went to a yacht club near San Diego, where police say he attempted to steal a boat and flee to Mexico.

He aborted the attempted theft when the boat's propeller became entangled in a rope, law enforcement officials said. It was then that he is believed to have headed to Riverside, where he allegedly shot two police officers.

"He pointed a handgun at the victim [at the yacht club] and demanded the boat," said Lt. David Rohowits of the San Diego Police Department.

Police say the rifle marksman shot at four officers in two incidents overnight, hitting three of them: one in Corona, Calif., and the two in Riverside, Calif.
