Audi shows off self-driving, self-parking A6 Avant and RS7 Sportback

The future of driving is here, at least for Audi, which demonstrated its self-driving car features on the Audi A6 Avant at the International Consumer Electronics Show this year. Using ultrasonic sensors, radar, and video cameras, the car can allow drivers in heavy traffic to engage an autopilot system that will pilot the car up to 37 mph. Audi also showed off its concept RS7 Sportback, which has the capability for remote control parking for drivers.

Audi's new autonomed cars will erase the pain of driving in traffic jams or squeezing into tight parking spots, in addition to letting drivers feel like a certain famous fictitious secret agent.
In "Tomorrow Never Dies," James Bond eludes his captors by hiding on the back seat of his car and driving it via a remote control located in his mobile phone. When the film came out in 1997, some remarked that it was a little far-fetched, but autonomous and remote-control car technologies have existed for many years, and now, a little more than a decade later, Audi is essentially demonstrating the exact same features -- minus the heat-seeking missiles and smokescreen -- on two of its executive sedans.
Whereas in the Bond film, the technology was designed to protect the dashing secret agent from henchmen working for a maniacal media baron, Audi's systems have been installed in two vehicles, one created to save drivers from the drudgery of gridlocked roads and the other from the stress of trying to park and exit a vehicle.

First publically demonstrated in an Audi A6 Avant as part of this year's International Consumer Electronics Show, when a driver encounters stressful driving conditions such as heavy congestion or major traffic jams, an autopilot system can take over and guide the vehicle with perfect lane discipline at speeds of up to 37mph (60 km/h). Using ultrasonic and radar sensors as well as video cameras, the car can maintain a safe distance from the vehicle in front and reduce speed or apply the brake if necessary. It is also aware of blindspots and of distances relevant to crash barriers and highway markings and can even react cooperatively to other cars attempting to change lane or overtake. All of which allows the driver ultimate peace of mind and a chance to relax when those around him or her are becoming more and more stressed.
Parking a car is one thing, but parking a car in a tight space and then managing to exit it, along with the other passengers, babies, strollers and luggage without bumping doors against walls or even other cars is another.

The Audi RS7 Sportback concept offers remote control parking via smartphone app.
Using the same sensors, the concept Audi RS7 Sportback can not only park itself in any space large enough to accept it, the car can park itself via remote control. Simply stop the car next to the space and get out, then, using a smartphone to connect to the vehicle, order it to park and switch off its ignition. What's more, when it's time to leave, the car can be instructed to autonomously exit the space and pull up alongside the driver and his or her passengers.
When asked how long consumers would have to wait before these features finally make it in to their cars, Audi spokesperson Holly Robinson responded: "From the technical point of view, we are sure that a system as presented in Vegas can be in the market not later than the end of this decade."

N.Korea Tests New Missile Engine Before Nuke Test

                         N.Korea Tests New Missile Engine Before Nuke Test

North Korea conducted combustion testing for the engine of a mobile long-range missile presumed only a day before its third nuclear test last week, it has emerged.

The missile is presumed to be the KN-08, an intercontinental ballistic missile with a range of 5,000 to 6,000 km. It was unveiled in a military parade on nation founder Kim Il-sung's 100th birthday on April 15 last year, but was then largely believed to have been a fake. The engine test suggests it was a little more than that.

A South Korean government official said the North carried out combustion testing at a missile launch site in Tongchang-ri, North Pyongan Province on Feb. 11.

Seoul presumes that the North is still conducting testing to improve the engine, which suggests it'll be difficult for the regime to test-launch a real missile soon.

Since late 2011, the North has conducted several engine combustion tests for long-range rockets or new missiles but most failed until early last year. The North launched space rockets in April and December as an apparent cover to test ICBM technology, claiming their aim was to put peaceful satellites into orbit.

A South Korean military source speculated, "It seems that the North intentionally conducted the test to coincide with the time when a U.S. reconnaissance satellite was monitoring the Tongchang-ri test site, apparently with the aim of improving negotiation leverage.

The KN-08 is estimated to be 18 m long and 2 m in diameter, about 6 m longer in length and 50 cm thicker than the Musudan missile, whose range is 3,000 to 4,000 km and already deployed warfare-ready. The KN-08's range is likely to cover Alaska and Hawaii.

In the parade last year, it was carried on a mobile launch platform made in China, whereas previous long-range rockets are launched from large fixed launch pads. Mobile missiles are threatening because they are harder to pinpoint and destroy.

Some experts wonder whether the North will conduct a full-scale launch of the KN-08 if additional sanctions are imposed by the UN Security Council over the latest nuclear test.

In a statement on Feb. 12, the North's Foreign Ministry said, "If the U.S. makes this situation complex in hostility, we will come up with second and third reactions."

RobotCar - an inexpensive alternative to Google's self-driving cars (w/video)

(Nanowerk News) Taking a different approach to Google's self-driving cars, Oxford University has come up with a new autonomous car, which can drive itself, interact safely with other road users and can use roads efficiently.
RobotCar is a modified Nissan LEAF. Unlike Google's system that uses GPS, RobotCar uses lasers and cameras which are subtly mounted around the vehicle. It also takes up some of the boot space is a computer which performs all the calculations necessary to plan, control speed and avoid obstacles. Externally it's hard to tell this car apart from any other on the road.
Robotcar
The base vehicle is a Nissan LEAF - an all-electric car. The car has an off-the-shelf computer in the boot connected to various cameras and lasers hidden around the car’s body.
The company has not used GPS. It believes, even when GPS is available, it does not offer the accuracy required for robots to make decisions about how and when to move safely. Even if it did, it would say nothing about what is around the robot, and that has a massive impact on autonomous decision-making.
RobotCar, which uses lasers and cameras, constantly monitors the road ahead to look for pedestrians, cars or anything that could pose a danger.
"Currently, the system leverages an array of low-profile stereo cameras and lasers that rings up at about £5,000 (approximately $7,750), but the next goal is to knock the price down to £500, and eventually to a cool £100 (roughly $150)," reports Engadget.
RobotCar constantly monitors the road ahead to look for pedestrians, cars or anything that could pose a danger. If an obstacle is detected the vehicle comes to a controlled stop and waits until the obstacle has moved out of the way. Once clear the car simply accelerates and continues its journey.
There are three computers onboard. The iPad, the LLC (Low Level Controller) and the MVC (Main Vehicle Computer). The iPad runs the user interface and demands constant attention from the LLC. If any of these computers disagree the driver will not be able to start autonomous driving. If at any point there is a problem when the car is in control the human driver is prompted to take control, if they fail to do so the car is automatically brought to a stop.
The whole user experience is provided by an iPad which quickly guides the user through the few checks that are needed to induce autonomy. At any time the driver can take back control of the car by touching the brake - it's exactly like cruise control in an existing vehicle - only this time the car sees obstacles, controls speed and steering.
The company has modified the base Nissan LEAF systems to allow complete fly-by-wire control. Everything from the steering to the indicators can be manipulated by the main vehicle computer in the boot.
RobotCar senses the world in two main ways. The first uses a pair of stereo cameras to assess the road and navigate, much like a human driver's eyes. The second is a little different and uses several lasers mounted around the vehicle. These sensors assess the 3D structure of world and also improve performance at night. The vehicle is all electric. This means no carbon emissions.

Facebook 'bug' bugs Zuckerberg's account, reveals private pics

Facebook 'bug' bugs Zuckerberg's account, reveals private pics

Facebook spam hits Zuckerberg’s account
Facebook spam hits Zuckerberg’s account
New York: A security glitch in Facebook gave users access to Mark Zuckerberg's private pictures, including a few with his girlfriend.
    
The social networking site has repeatedly come under attack for its constantly changing privacy and security features that at times made private information, including photos and comments, publicly available.
    
The security flaw, first exposed by a bodybuilding website, was discovered on Tuesday by Facebook which went into damage control mode after the glitch made it possible to access its founder Zuckerberg's private photos with his girlfriend and friends.
    
Over two dozen photos of Zuckerberg were visible online, including those with his girlfriend Priscilla Chan at his California home, one with President Obama at the White House, some showing him cooking meals, hanging out with friends, playing with his puppy and distributing Halloween candy to kids.
    
In a statement, Facebook said it had discovered a "bug" that allowed anyone to view a limited number of another user's most recently uploaded photos irrespective of the privacy settings for these photos.
    
"This was the result of one of our recent code pushes and was live for a limited period of time. Upon discovering the bug, we immediately disabled the system, and will only return functionality once we can confirm the bug has been fixed."
    
The bug was in the site's tool through which users can report inappropriate and offensive content. A user at the website 'Bodybuilding.com' clicked on a person's profile picture, then reported to Facebook that it contained nudity or was of inappropriate nature.
    
Facebook, with more than 800 million users worldwide, is expected to go public next year, a move that will value the company the college dropout founded in his Harvard dorm at 100 billion dollars.
    
However, as Facebook's popularity skyrocketed, it took some backlash for making users' information accessible to marketing companies and advertisers.
    
Last month, Facebook reached a settlement with the US Federal Trade Commission, which had charged that the company "deceived consumers by telling them they could keep their information on Facebook private, and then repeatedly allowing it to be shared and made public."
    
The settlement states that Facebook is required "to establish and maintain a comprehensive privacy programme.

Zuckerberg weds his long time lady love

New York: Facebook's billionaire founder Mark Zuckerberg updated his relationship status on his social networking site to 'married' - he has tied the knot with his long time girlfriend 27 year old Priscilla Chan in a private ceremony at his California home.
The surprising move came just a day after Facebook went public through one of the largest initial public offerings and its shares began trading on the Nasdaq.
Zuckerberg wrote about the big event in his life on his Facebook timeline, with a status update that read, "Married Priscilla Chan" on May 19.
The ceremony took place in Zuckerberg's backyard at his Palo Alto home in California before fewer than 100 guests yesterday. An accompanying picture shows a smiling Zuckerberg dressed in a simple dark blue suit, white shirt and wearing a tie. Chan is in an elegant sleeveless laced white wedding gown with a veil falling over her shoulders. A string of bulbs are hung in the background which is Zuckerberg's backyard.
The picture got over 131,000 likes within the first 30 minutes of Zuckerberg posting the status update.
The couple met at Harvard and have been together for more than nine years. Chan's Facebook page also had the updated relationship status with the message "married to Mark Zuckerberg."
The marriage capped an extremely eventful week for the couple. Zuckerberg celebrated his 28th birthday on Monday, May 14. Days later Facebook, which was founded by Zuckerberg in 2004 in his Harvard dorm, became went public through an IPO that pegged the value of the world's most popular social network site at 104 billion dollars.
The same week Chan graduated from the University of California, San Francisco. Chan studied medicine and is now a doctor of pediatrician. On her graduation day, Zuckerberg had written on his Facebook page, "I am so proud of you Dr Chan."

Obama pledges new deal for US middle class in state of the union address
President urges Congress to work 'on behalf on the many' while laying out plans to tackle immigration and gun control

Barak Obama has pledged in the annual state of union adress to use his second presidential term to restore "the basic bargain" which built the US into the world's greatest economic power by ensuring prosperity for the great bulk of Americans and not the privileged few.
The president made wide-ranging proposals for investments in schools and infrastructure, and a sharp increase in the minimum wage to ensure that "no one who works full-time should have to live in poverty" as he told Congress that it is this generation's task to return to a time when US governments represented all the people. But he also pledged that his proposals will not add to the US's burgeoning deficit.
"It is our unfinished task to restore the basic bargain that built this country – the idea that if you work hard and meet your responsibilities, you can get ahead, no matter where you come from, what you look like, or who you love," the president said. "It is our unfinished task to make sure that this government works on behalf of the many, and not just the few; that it encourages free enterprise, rewards individual initiative, and opens the doors of opportunity to every child across this great nation of ours."
Obama used the speech to call for fairness and decency in other areas of American political life – from immigration reform and gay rights to legislation to protect women from violence and to reduce the terrible toll in lives claimed by guns.
But it was jobs and the economy that the president built his speech around. He said that after a gruelling recession, the economy has turned around and job numbers are rising. "Together, we have cleared away the rubble of crisis, and can say with renewed confidence that the state of our union is stronger," he said.
But Obama said that many of those who have worked hard to pull America out of the economic crisis have been left behind. "Our economy is adding jobs – but too many people still can't find full-time employment. Corporate profits have rocketed to all-time highs – but for more than a decade, wages and incomes have barely budged," he said.
The president said it was wrong that in such a rich country working people should live hand-to-mouth.
"Tonight, let's declare that in the wealthiest nation on Earth, no one who works full-time should have to live in poverty, and raise the federal minimum wage to $9 an hour. This single step would raise the incomes of millions of working families. It could mean the difference between groceries or the food bank; rent or eviction; scraping by or finally getting ahead. For businesses across the country, it would mean customers with more money in their pockets," he said.
The Republican speaker of the House of Representatives, John Boehner, and members of his party remained seated as Democrats rose to applaud.
In a speech that at times echoed the view of a foregone era that it is for the government to lead when capitalism cannot provide, Obama said he also recognised that there are parts of the US – "factory towns decimated from years of plants packing up, inescapable pockets of poverty, urban and rural" – where finding even a minimum wage job is hard. The president said he will direct money toward providing work "rebuilding vacant homes in run-down neighbourhoods", and targeting "resources at public safety, education, and housing".
He announced a "Fix-It-First" programme to address the most urgent repairs of the US's worn infrastructure "like the nearly 70,000 structurally deficient bridges across the country". But in a recognition of modern political realities, Obama said the private sector must have a role.
"To make sure taxpayers don't shoulder the whole burden, I'm also proposing a Partnership to Rebuild America that attracts private capital to upgrade what our businesses need most: modern ports to move our goods; modern pipelines to withstand a storm; modern schools worthy of our children," he said.
Recognising that many Americans and members of Congress are as worried about the US's rising debt as they are about falling earnings, the president pledged that his proposals would not add to the country's debt.
"Nothing I'm proposing tonight should increase our deficit by a single dime. It's not a bigger government we need, but a smarter government that sets priorities and invests in broad-based growth," he said. Republicans are suspicious of that claim. Newt Gingrich, the former House speaker, said that commitment would sink the president's plans.
In the official Republican response to Obama by Florida senato, Marco Rubio – a Cuban immigrant chosen as his party attempts to reposition itself as more moderate after its defeat in the presidential election and to win back Latino voters driven away by Republican legislation and rhetoric on immigration – accused the president of wanting to further expand government with "tax, borrow and spend" policies. He said Obama was falsely blaming the rich not paying enough tax for the economic recession when it was a "housing crisis created by reckless government policies" that was to blame.
"I don't oppose your plans because I want to protect the rich. I oppose your plans because I want to protect my neighbours," Rubio said of the president. "This opportunity – to make it to the middle class or beyond no matter where you start out in life – it isn't bestowed on us from Washington. It comes from a vibrant free economy where people can risk their own money to open a business."
Obama warned of the devastating effect of about $1tn worth of budget cuts that will automatically kick in this year if no agreement is reached in Congress to reduce the deficit.
"These sudden, harsh, arbitrary cuts would jeopardise our military readiness. They'd devastate priorities like education, energy, and medical research. They would certainly slow our recovery, and cost us hundreds of thousands of jobs," he said.
But the president said that Republican proposals to protect defence spending by cutting education, job training and government health spending even deeper was an "even worse" idea.
Obama said he would agree to reform of Medicare and Medicaid, which provide healthcare to the elderly and very poor, but by changing how the government pays for services.
Instead of cuts to services, the president said that what is required is to make the rich and big business pay their fair share. "To hit the rest of our deficit reduction target, we should do what leaders in both parties have already suggested, and save hundreds of billions of dollars by getting rid of tax loopholes and deductions for the well-off and well-connected. After all, why would we choose to make deeper cuts to education and Medicare just to protect special interest tax breaks? How is that fair? How does that promote growth?" he said.
Obama used the prospect of better educated and better trained workers to press for immigration reform.
"Our economy is stronger when we harness the talents and ingenuity of striving, hopeful immigrants," he said. "Real reform means establishing a responsible pathway to earned citizenship – a path that includes passing a background check, paying taxes and a meaningful penalty, learning English, and going to the back of the line behind the folks trying to come here legally."
But in a gesture to Republicans who want tighter controls to stem the inflow of undocumented aliens, Obama promised tighter control of borders.
Still, Rubio responded by saying that existing laws need to be better applied before the door is opened to more immigrants to remain legally.
