The U.S. military says it is evaluating its policies after a global map of fitness activity drew attention to possible security concerns regarding locations of overseas bases and soldier movements.
Strava published its so-called heat map of user activity in November showing the routes millions of users walked, ran and biked, with the most frequent routes showing up in brighter colors. The company says it excluded activities that users marked as private or ones that took place in areas people did not want to make public.
The activities were tracked using GPS-enabled devices from manufacturers like Fitbit, Garmin and Polar, and even with the exclusions, Strava said its map included 1 billion activities between 2015 and September 2017.
The Washington Post reported on the heat map and its implications, highlighting a Twitter post by Australian student Nathan Ruser who shared the link to the Strava site Saturday.
“It looks very pretty, but not amazing for Op-Sec [operational security]. US Bases are clearly identifiable and mappable,” Ruser wrote.
The map shows the most activity in places like the United States, Western Europe, Japan and Brazil. In Iraq, Syria and Afghanistan, activities show up bright against otherwise dark terrain, including in multiple places where the U.S. military is known to have bases or be active.
The devices that transmit the data can be used in several ways, including for example a short run or keeping track of the steps a person takes throughout the day. The result can be lines on the heat map showing loops around the perimeter of a military installation where people exercise or showing where they move from place to place throughout the facility, or elsewhere.
“DoD takes matter like these very seriously and is reviewing the situation to determine if any additional training or guidance is required, and if any additional policy must be developed to ensure the continued safety of DoD personnel at home and abroad,” Department of Defense spokeswoman Maj. Audricia Harris said.

New York State Attorney General Eric Schneiderman has launched an investigation of a firm that allegedly sold millions of fake followers to social media users.
The company, Devumi, sold more than 200 million fake followers, or bots, to celebrities, sports stars, and politicians, The New York Times reported.
“Impersonation and deception are illegal under New York law,” Schneiderman tweeted. “We are opening an investigation into Devumi and its apparent sale of bots using stolen identities.”
The Times reported that at least 55,000 of the bot accounts names, pictures, hometowns and other details taken from people on Twitter. The information was stolen from people in every U.S. state as well as dozens of countries, The Times said.
“The growing prevalence of bots means that real voices are too often drowned out in public conversation,” Schneiderman said. “Those who can pay the most for followers can buy their way to apparent influence.”
On social media, high follower numbers means greater influence and visibility, which can impact public opinion and offer lucrative financial deals for the account holders.
On its website, Devumi offers customers the chance to buy up to 500,000 followers for social media sites including Twitter, YouTube, LinkedIn, Pinterest and Vimeo, with prices starting at as little as $12.

Tokyo-based cryptocurrency exchange Coincheck Inc said Sunday it would return about 46.3 billion yen ($425 million) of the virtual money it lost to hackers two days ago in one of the biggest-ever thefts of digital money.
That amounts to nearly 90 percent of the 58 billion yen worth of NEM coins the company lost in an attack Friday that forced it to suspend withdrawals of all cryptocurrencies except bitcoin.
Coincheck said in a statement it would repay the roughly 260,000 owners of NEM coins in Japanese yen, though it was still working on timing and method.
Theft and security
The theft underscores security and regulatory concerns about bitcoin and other virtual currencies even as a global boom in them shows little signs of fizzling.
Two sources with direct knowledge of the matter said Japan’s Financial Services Agency (FSA) sent a notice to the country’s roughly 30 firms that operate virtual currency exchanges to warn of further possible cyber-attacks, urging them to step up security.
The financial watchdog is also considering administrative punishment for Coincheck under the financial settlements law, one of the sources said.
Japan started to require cryptocurrency exchange operators to register with the government in April 2017. Pre-existing operators such as Coincheck have been allowed to continue offering services while awaiting approval. Coincheck’s application, submitted in September, is still pending.
Coincheck told a late-Friday news conference that its NEM coins were stored in a “hot wallet” instead of the more secure “cold wallet,” outside the internet. Asked why, company President Koichiro Wada cited technical difficulties and a shortage of staff capable of dealing with them.
Shades of Mt. Gox
In 2014, Tokyo-based Mt. Gox, which once handled 80 percent of the world’s bitcoin trades, filed for bankruptcy after losing around half a billion dollars worth of bitcoins. More recently, South Korean cryptocurrency exchange Youbit last month shut down and filed for bankruptcy after being hacked twice last year.
World leaders meeting in Davos last week issued fresh warnings about the dangers of cryptocurrencies, with U.S. Treasury Secretary Steven Mnuchin relating Washington’s concern about the money being used for illicit activity.

Melinda Gates has launched a high-level international commission to spark new thinking on how developing countries can best harness new technologies to reduce poverty. The wife of Microsoft founder and philanthropist Bill Gates spoke at the launch of the commission in Nairobi on Thursday.
The 11-member commission aims to promote use of technology to fight poverty across Africa and provide opportunities for the poor.
Melinda Gates, co-founder of the Bill and Melinda Gates Foundation, said the newly launched commission would create opportunities for everyone.
“Let us unleash the opportunity here of all the amazing entrepreneurs, because they are the ones. The markets then will scale these great ideas and so we want to make sure that part of this world we are thinking about everybody, not just the people in the capital cities,” she said.
The commission will be co-chaired by Mrs. Gates, former Indonesian finance minister Sri Mulyani Indrawati and Zimbabwean philanthropist Strive Masiywa.
The team with the help of researchers will deliberate new ideas like robotics, 3D printing, nanotechnology and blockchain to reduce poverty. They will also push for policy recommendations to help government navigate the ever changing technology.
According to the United Nations, half of the world poorest people live in Africa, and by 2030 about 400 million people in Africa will be poor.
The United Nations estimates 10 million people in Africa every year enter the job market. Experts note the continent needs more economic growth and employment to bring poverty down.
Strive Masiyiwa, who is founder of Econet Group, a telecommunications company, says Africa will have to create a better environment to benefit from the opportunities presented by technology.
“If we create the right incentives, we can begin to create African venture capitalists who support entrepreneurs on the ground, but they will require incentives, the entrepreneurs themselves need support we need to open our markets constantly deregulate. Deregulation must be a continuous process,” says Masiyiwa.
The everyday use of technology has spread in Africa, marked by an increase in mobile money marking and greater use of the internet.
But some experts question whether this progress has enhanced economic growth and improved people’s lives.

The young woman, new to the grind of Chinese factory life, knew the man who called himself Kalen only by the photo on his chat profile. It showed him with a pressed smile holding a paper cup in a swank skyscraper somewhere late at night.
Yu Chunyan and her friends didn’t know what to make of him. Some thought his eyes were shifty. Others said he looked handsome in a heroic sort of way.
Yu was among the doubters. The daughter of factory workers, Yu paid her way through college by working in factories herself. She and thousands of other students had toiled through the summer of 2016 assembling iPhones at a supplier for Apple Inc., but they hadn’t been paid their full wages.
Kalen was offering to help – and asking nothing in return.
This struck Yu as suspicious. If there was one thing she had learned in her 23 years it was this: “There’s no free lunch.”
Disputes like these often don’t go well for workers in China. But over the years, suicides and sweatshop scandals have pushed some companies, like Apple, to reconsider their approach to workplace fairness.
Today, a growing number of brands, including Apple, Nike Inc., Gap Inc., Levi Strauss & Co., and the H&M Group prioritize transparency and take public responsibility for conditions throughout their global supply chains. Labor rights groups like the one Kalen worked for, China Labor Watch, can play a useful watchdog role for these companies, by helping them understand what’s really going on at their suppliers.
But not everyone has embraced this new approach.
When China Labor Watch confronted Ivanka Trump’s brand with charges of labor abuses at its Chinese suppliers, her company refused to engage. It made no public effort to investigate the allegations: forced overtime, pay as low as $1 an hour, and crude verbal and physical abuse – including one incident in which a man was hit in the head with the sharp end of a high-heeled shoe.
Ivanka Trump, who still owns but no longer closely manages her namesake brand, stayed silent. Neither she nor her brand would comment for this story.
Unlike Apple, her brand doesn’t publish the identities of its manufacturers. In fact, its supply chains have only grown more opaque since the first daughter took on her White House role.
But as the summer of 2016 was ending, Yu Chunyan had no idea she was about to get an education in geopolitics and corporate social responsibility. She wanted one thing only: her wages. And she saw one way to get them: The stranger with the odd English name.
Kalen and China Labor Watch would link Yu not just to Apple, but ultimately, to the daughter of the President of the United States. Their intersecting stories highlight the contrasting approaches Apple and Ivanka Trump’s brand have taken to workplace fairness – and the impact those decisions have had on the ground in China.
It would take Yu more than a year to discover who Kalen really was.
No help came
When Yu was still a baby, her parents went to work at a factory in one of the southern boomtowns of Guangdong province. As a child, entire years passed without a visit from her mother or father.
This was an ordinary enough fate in China, and Yu grew up bouncing between her grandparents’ homes in central China’s Henan province.
The first extraordinary thing that happened to Yu was her high school entrance exam. She aced it, despite her middling grades, scoring even higher than the known overachievers in class.
The shock of her accomplishment gave Yu a soaring sense of her own potential. She raced to tell her mother.
“Oh,” was her mother’s stony response.
Yu’s test score opened the possibility, unsettling to her parents, that she would not marry young, produce grandchildren and start earning money for the family.
Her parents regarded aspiration warily: Excellence would only lead to inflated expectations. Just the sort of thing, her parents feared, that could crush a person. Better to remain where you are, bound by a certain, riskless horizon.
Yu did not agree. “As long as I want something, I will get it,” she decided.
Her parents let her stay in school, but if Yu wanted to go to college, she would have to pay her own way.
And so she did. She enrolled in a college in Henan province. Ultimately, she wanted to do something creative, like design; in the meantime factory jobs weren’t a bad way to make money.
In July 2016, Yu took her place on the assembly line at Jabil Inc.’s Green Point factory in Wuxi, a city near Shanghai. She spent her 12-hour shift snapping the back cover of the iPhone 7 into a mold and passing it down the line.
“It seems simple,” Yu said. “But if you work the whole day doing this your hands will be really tired. Normally, it’s a job for a man.”
Her group’s production quota kept going up, climbing from 2,000 to 50,000 units a day, Yu said. She got dizzy. Her hands hurt. She thought: “When will it be over?”
In August 2016, she quit, ignoring admonitions that her pay would be docked 500 yuan ($79, at today’s rates) for leaving early.
Yu made the 12-hour train trip back to school in Henan and on Sept. 10, her final paycheck hit her bank account. It was an ugly surprise. She was 1,100 yuan short of the 4,930 yuan she expected. Her salary was supposed to cover her tuition. Now it didn’t.
“I was furious,” she said. “I thought that no matter what I would get my money back.”
She called the factory and the labor broker who had gotten her the job only to be informed of a range of surprising fees, some legitimate, others not.
Yu called the labor union at Green Point for help. “Useless,” she said. She called the local labor bureau, but no one picked up.
On Chinese social media, Yu found a chorus of despair as other students – the children of farmers, factory and construction workers – vented about being stiffed on WeChat, QQ and Weibo.
“Everyone had an attitude like, ‘Well, it has nothing to do with me,'” said Zhuang Huaqian, an electrical engineering student at Hunan University of Technology, who spent the summer assembling iPhones in a moon suit of dust-free clothing.
The head of one of the labor brokers in the dispute, Ding Yan, said his company had done nothing wrong. “Wages are our bottom line. We will never underpay them,” he said. “I wouldn’t risk this brand.”
Frustrated, the students took their case to the press. A few articles appeared detailing their complaints, but Yu and another student said postings began to disappear. Were they being censored, they wondered?
The local government published an article on an official Weibo account that said authorities acted swiftly and more than 2,100 students had been repaid. The post included complaint hotlines workers could call.
Chen Jianbin, head of Wuxi’s labor security supervision unit, said his team had to sort through verbal contracts, informal intermediaries and fake complaints apparently lodged by people paid to smear competing labor agencies.
“We were trying our best to help,” said Chen. “Those students’ lives were not easy.”
But many students hadn’t gotten their money back.
Beneath their fury was growing desperation. Every lever of redress they had tried failed them. They had appealed for help to forces they thought they could believe in – society, the government – but no help came.
‘The world is full of good people’
There was, however, one guy, who did offer help. He called himself Kalen.
Kalen had worked in a phone factory himself, 13 years earlier, polishing cheap landline phones for a Chinese brand at a factory in Shenzhen. Back then, he didn’t realize he was being underpaid until he wandered into the office of a local labor rights group one day and learned that he wasn’t earning the legal minimum wage.
That knowledge electrified him. He devoured books about labor rights in the group’s reading room as he prepared his case. Two months later, he won 3,000 yuan in back pay through a local arbitration panel.
Kalen wondered how many other workers out there were like him, ignorant of their rights. He quit his factory job and dedicated himself to teaching workers how to use China’s laws to protect themselves.
Kalen brought his evidence-based approach to China Labor Watch, a group many of the students had never heard of before. He told them about the group’s past work with Apple suppliers and taught them how to calculate what they were owed. He admonished them to be honest as he gathered details about working hours and pay from over 200 workers.
“Seek truth from facts,” he wrote them on QQ.
In September, China Labor Watch asked Apple to intervene. The company sent a local team to investigate, reporting that 2,501 students had received back wages.
But many said they still hadn’t been fully paid.
When Kalen asked for a volunteer to write a letter to Apple, Yu was torn: Could she get kicked out of school for speaking out?
“It was so hard for me to make this money,” she said. “As long as there was a little bit of hope left I wanted to try.” She stayed up past midnight writing down everything that had happened.
On Sept. 28, Li emailed Yu’s letter to Apple.
Five days later, Apple wrote back: It had done further investigation and would ensure workers got paid for their day of training and extra work during meal breaks.
“Jabil invested hundreds of hours of staff time to contact approximately 17,000 employees,” Eric Austermann, Jabil’s vice-president of social and environmental responsibility wrote in an email to AP. “Although often lacking an email address, phone number, or other standard contact information, Jabil located all but about 5 percent of these employees, all of whom have been paid in full.”
The workers received over 2.7 million yuan ($426,000, at today’s rates), according to Jabil Green Point and an October 2017 email from Apple to China Labor Watch.
Apple declined to the comment on the case.
The students’ payments came in a few hundred or thousand yuan at a time. This was money for school, for food, a way to stay out of debt. By the end of October, Yu had gotten back everything she was owed.
She was impressed. She amended the letter she had written for Kalen, turning it into a testimonial and a statement of personal intent. China Labor Watch posted it on its website.
“Due to this experience, I am confident that the world is full of good people, people who make selfless contributions,” Yu wrote. “I wish to join a public interest organization. I wish to help others.”
But China was changing. Hundreds of human rights lawyers and activists had been swept up in a crackdown against perceived threats to the ruling Communist Party. Those with foreign ties, like China Labor Watch, were viewed with particular suspicion.
Yu had yet to grasp the perils of her growing idealism.
It could have been me
After Chinese New Year, Yu moved to Shanghai, a city she had only seen in pictures, to take a job at an interior design company. In March 2017, five months after she’d received her back pay from the factory, Yu reconnected with Kalen on WeChat.
Kalen told her China Labor Watch might need people to work undercover.
China Labor Watch was closing in on factories that made Ivanka Trump merchandise, including Ganzhou Huajian International Shoe City Co.
But the thought of returning to the grind of factory life was more than she could stomach.
“I needed to push myself forward,” she said. She wanted to learn English, dress better, lose weight.
China Labor Watch ultimately sent two men to work undercover. The group obtained a video of a manager berating a worker for apparently arranging shoes in the wrong order.
“If I see them f—ing messed up again,” the manager yells, “I’ll beat you right here.” Another worker was left with blood dripping from his head after a manager hit him with the sharp end of a high heeled shoe, according to three eyewitnesses who spoke to the AP.
The Huajian Group, which runs the factory in Ganzhou, denied all the allegations as “completely not true to the facts, taken out of context, exaggerated.” In April, China Labor Watch laid out its initial findings in a letter to Ivanka Trump at the White House.
She did not respond.
Over the years, Samsung Electronics Co. Ltd., Gap Inc., Target Corp., Wal-Mart Stores Inc. and other companies took China Labor Watch seriously enough to respond to criticisms or meet Li in person, according to emails and meeting notes reviewed by AP. Walt Disney Co. severed its relationship with at least one supplier after China Labor Watch exposed poor working conditions.
“We did an investigation on Apple because Apple is a big American company,” Li said. “If Apple changes, the other companies will follow. Now Ivanka is the most famous person among all these companies. If she can change, the other companies will too.”
But that plan backfired.
At the end of May, three China Labor Watch investigators were arrested, accused of illegally using secret cameras and listening devices.
One of them was investigator Hua Haifeng. Police had warned Hua to drop the Huajian investigation, but he pushed ahead anyway, Li said.
A wiry man not easily moved to alarm, Hua seemed to accept fear as the cost of his decision to live his life as an expression of his values.
In more than a decade working on labor rights in China, Hua had helped thousands of workers get back money they were owed, all the while half-wondering when he’d be forced to stop.
Now that he had, Hua, 36, was cut off from his wife and two young children.
Inside the Ganzhou City Detention Center, Hua shared a toothbrush with strangers. Locked in a cell so crowded there weren’t enough wooden boards to sleep on, Hua stretched out at night on a concrete floor next to a bucket that served as the toilet for around 20 men. The men added water and soap, hoping the bubbles might somehow take the stench out of human waste. It didn’t work.
It was the first time in China Labor Watch’s 17-year history that its investigators had been arrested. Police raided the group’s Shenzhen office and carried away computers and documents, Li said.
From his office in New York, Li worked frantically to get the men out of jail. He was convinced the shift in fortune was due to the target of their inquiry: a brand owned by the daughter of the U.S. president. But he had no proof.
Ivanka Trump – and her brand – said nothing about the arrests.
Where is Kalen?
Days after the arrest, Yu Chunyan took a new job at a design company in Shanghai, but something lingered from her experience at the Green Point factory. “I’d prefer work that can help more people,” she said.
She got a friend request from China Labor Watch’s Li Qiang. She messaged Kalen to check Li out.
Kalen never replied. She wondered what had happened to him.
On June 5, the U.S. State Department called for the immediate release of the three China Labor Watch investigators.
China’s Ministry of Foreign Affairs responded that other nations “have no right to interfere with our judicial sovereignty.” State-owned media reported that the trio had tried to steal trade secrets and sell them overseas.
Li Qiang wrote to Ivanka Trump at the White House on June 6, describing what he called “extreme working conditions” in her supply chain. “Your words and deeds can make a difference in these workers’ lives,” he wrote.
He got no reply.
Her brand has called its supply chain integrity “a top priority,” but also maintains that its suppliers are overseen by licensees – companies it contracts with to make tons of Ivanka Trump handbags, shoes and clothes.
The brand said its shoes had not been produced at the Huajian factory since March, though China Labor Watch obtained an April production schedule for nearly 1,000 pairs of Ivanka Trump shoes due in May.
In late June, after 30 days in jail, the three China Labor Watch investigators were released on bail. Hua carried his son in his arms as he walked out of a police station in Ganzhou.
Hua declined to be interviewed for this story. His lawyer said police ordered him not to speak with the media. His bail conditions dictated that he must check in weekly with police and cannot travel without permission. That, plus the cloud of criminal suspicion that clung to him in his small hometown, made it hard to get a job.
In July, Hua asked police for permission to take a family vacation in the Wudang mountains, three hours away. After articles came out in the foreign press quoting Hua, half a dozen plainclothes policemen appeared at a restaurant where Hua was having dinner with his family and tapped him on the shoulder. The next morning they escorted him home, leaving his wife, Deng Guilian, to wander through Taoist temples alone with the kids.
With her husband out of work, Deng got a job selling drinks and snacks at a local karaoke parlor from 6 p.m. until 2 a.m. After her shift, she heads to a nearby dormitory where she and a female co-worker share a bed with a Snoopy headboard.
She gets three days off a month to see her four-year-old son, Bo Bo, and seven-year-old daughter, Chen Chen.
“They seem accustomed to not having their mom,” Deng said, flashing an uneasy smile.
Each Monday morning after dropping his kids at school, Hua makes the short drive past weedy lots and a factory spewing thick white smoke to check in with the local police in Nanzhang County.
At first they lectured him: Change careers. Don’t speak out. Live a normal life. Now, he usually just signs his name, his wife said, but it is clear that missteps can quickly draw the wrath of local authorities.
Police in Nanzhang County, Ganzhou city and Jiangxi province did not respond to requests for comment.
In October, Li Qiang again wrote to Ivanka Trump and her brand.
He said he got no response.
Ivanka Trump’s actions show “that she does not care about these workers who are making her products, and is only concerned with making profits,” Li said in an email. “As a public figure, she has the ability and resources to not only work on labor conditions at her own brand’s factories, but also to help improve labor conditions of the global supply chain as a whole. However, she did not use her influence to do these things.”
An ordinary person
Shortly after 6 p.m. on an October evening, Yu Chunyan left her office and walked through Shanghai’s former French Concession, the wealthy heart of China’s most prosperous city. She passed rows of thick plane trees, black against a darkening sky, and stepped into a discreet tea house.
Yu slid open the wooden door of a private room and peeked inside with a wide, nervous smile at the AP journalists she had agreed to meet. A chunky, colorless sweater hung off her body and her stocking feet poked out of white sandals despite the cold.
Yu slipped off her shoes and took a seat at the sunken table, doing her best to avoid the list of fancy teas glowing from a scrollable iPad menu. She began to talk about Kalen, and pulled out her phone to flip to their exchanges on WeChat.
There, in his tiny profile photo, was a familiar face.
“Do you know him?” she asked, surprised.
AP had been writing about him for months.
Kalen was Hua Haifeng.
Yu had no idea that her Kalen was the same Hua Haifeng who had been arrested while investigating Ivanka Trump suppliers. She listened, still and silent, to news of interrogations and surveillance, his son’s sudden nightmares, the jail and the bucket of urine.
Her eyes welled. Elegant cakes lay untouched in front of her.
An hour later, she sent a WeChat message to Kalen.
“Do you have to take risks to work in your industry?” she asked.
Risks depend on politics, he wrote her, and the conditions of the country you live in. “From the beginning, I expected something like this could happen,” he told her. “So it’s not about bad luck. It was going to happen sooner or later.”
“If you had another chance, would you do the same thing?” she asked.
“Yes,” he answered. Hua told Yu that he had to live a life that embodied his values. He tried to be encouraging. “I am not saying that everyone has to pay that high a price.”
But Yu had a sense that Hua had run up against forces neither of them could fully grasp, much less defeat. In her mind, she was recalibrating the risks of idealism.
“I wouldn’t be able to do it,” Yu said.
In late November, she left Shanghai to go back and live with her parents.
“I want to be an ordinary person,” she said. “I don’t want to get involved with controversial things.”

Scientists and NASA officials who spearheaded development of a space-based missile defense system in the 1980s are urging its revival to counter emerging nuclear threats from North Korea and other rogue states.
False alarms over a North Korean missile attack on Hawaii this month indicate how Pyongyang’s nuclear capability has taken center stage as America’s main security concern since the North Korean government’s recent testing of ICBMs capable of reaching the United States.
The controversial U.S. Space Defense Initiative (SDI), started under President Ronald Reagan, was often ridiculed as “Star Wars” by critics in the U.S. Congress and media who balked at its high cost.
Many also questioned its effectiveness against the Soviet Union’s massive and sophisticated nuclear arsenal.
Back on the drawing board?
The program never got past the drawing board and was largely abandoned at the end of the Cold War.
“Everybody lost interest in SDI when the Soviet Union collapsed, but vast technological advances over the past 30 years and the emerging nuclear threat from North Korea revive its need and feasibility,” says Robert Scheder, a systems analyst with the RAND Corp. who designed the original model for space-based defense.
He conducted early simulations with a weapon system consisting of orbiting rockets equipped with sensor technology designed to intercept attacking missiles at the “boost phase,” or immediately after launch, before they can release decoys and countermeasures.
But there were significant technological shortcomings.
The fleet of satellite interceptor systems, also known as Brilliant Pebbles or Smart Rocks, could not entirely neutralize a Russian first strike involving thousands of nuclear warheads, according to Scheder.
They could, however, provide fail-safe protection against the threat now posed by North Korea, which can only launch a maximum of three or four missiles at a time, he told VOA in an interview from his home in Spain.
Critics: It’s still lacking
Thomas Roberts, a critic of space-based defense at the Center for Strategic and International Studies in Washington, says that even a small salvo of missiles could penetrate the space shield.
“The enemy can first launch a decoy to make a gap through the interceptor shield and then launch a salvo through that gap, which the Pentagon cannot close fast enough,” Roberts said.
At least 1,600 killer satellites would be needed to fully cover the Earth, costing defense dollars that could be just as effectively spent in deploying more conventional interceptor missiles and launching more satellites to track, surveil and identify incoming enemy missiles.
The calculated $100 billion cost for placing thousands of Brilliant Pebbles in orbit would have absorbed the entire U.S. defense budget in the 1980s.
“But the much smaller size of satellites and advances in miniaturization technology would limit the cost substantially in today’s terms,” Scheder said.
Commercially available space technology currently produced by Tesla and other contractors would also lower development costs and shorten deployment time, according to NASA experts.
The former SDI director, retired U.S. Air Force General James Abrahamson, has placed the current cost of Brilliant Pebbles at $20 billion.
Roberts said it would be at least $70 billion.
Congressional interest
SDI was shelved by President Bill Clinton and plans to revive it under successor George W. Bush were sidelined as counterterrorism and land wars in Afghanistan and Iraq took priority following the 9/11 terror attacks.
Growing concern with North Korea has moved the U.S. Congress to request new funding for space weapons research, according to a recent letter from the House Armed Services Committee to the White House.
The 2018 National Defense Authorization Act signed by President Donald Trump last month mandates the Missile Defense Agency to “begin research on space-based interceptors and re-establish the space test bed for demonstrating the relevant technologies.”
Abrahamson has said that the land-based anti-ballistic missile Terminal High Altitude Area Defense system, or THAAD, that currently employs Patriot surface-to-air batteries, cannot provide guaranteed protection against a rogue attack.
Simulations have shown that THAAD and the Navy’s AEGIS system have a 50 percent probability of intercepting ICBMs at terminal phases when they re-enter the atmosphere.
“They are tactical weapons designed to protect points in a set piece battle scenario,” Scheder said. But effective protection for entire countries or regions under threat by unstable regimes like Kim Jung Un’s can only be provided by satellite-operated area defense.
Questions remain
Critics of space-based weapons point to the possibility of satellite error in detecting a hostile launch.
Brilliant Pebbles impactors might also disintegrate upon re-entering the atmosphere in pursuit of an attacking missile before hitting it.
SDI proponents say that triangulations among Earth-based systems, mother satellites at upper orbits, and smart rocks at low orbit need to be tightened.
Scheder also says that the Smart Rock is a solid impactor designed to destroy a rocket with no explosive charge, so its collateral damage would be limited.
“An ICBM has about a 20-minute trajectory through space in which it’s vulnerable to a Smart Rock,” Scheder said. “Once it’s re-entered the atmosphere, land-based missiles have only seconds in which to hit it.”
Some weapon systems conceived for SDI, like laser or electromagnetic guns, could not provide adequate protection, according to the RAND expert.
Missiles can be painted to deflect laser rays and the heavy lift required for electromagnetic guns would complicate their placement in space.
There is a theoretical danger that a rogue nation or group with highly developed cyber war capacity could hack into a Brilliant Pebbles network and direct it against the U.S. or its allies.
But difficulties in countering a U.S. space shield could convince rogue powers of the futility of costly nuclear programs, according to Scheder.
He credits “Star Wars” with the Soviet Union’s decision to fold its arms race.

A federal jury in Wisconsin on Wednesday convicted a Chinese wind turbine company of stealing trade secrets, which nearly destroyed a U.S. manufacturer.
China’s Sinovel Wind Group does business in the United States.
“The theft of ideas and ingenuity is not a business dispute. It’s a crime and will be prosecuted as such,” U.S. Attorney Scott Blader said.
According to the government’s case against Sinovel, the company had an $800 million contract for products and services from Wisconsin-based American Superconductor (AMSC).
It said Sinovel conspired in 2011 with two company managers and a former AMSC employee to use computers in Austria to steal wind turbine technology and trade secrets from AMSC and install them on Sinovel turbines.
Sinovel never paid AMSC the $800 million.
Federal prosecutors said Sinovel’s crime cost AMSC dearly; investors dumped more than $1 billion in AMSC stock and about 700 workers lost their jobs, more than half of the company’s global workforce.
Sinovel will be sentenced in June.

The U.S. National Transportation Safety Board has opened an investigation in an accident involving a Tesla car that may have been operating under its semi-autonomous Autopilot system.
The board sent two investigators to Culver City, California, to learn whether the Autopilot was on and if so, how the car’s sensors failed to detect a firetruck stopped on a highway near Los Angeles on Monday.
This is the second time the safety agency will look in to a crash involving Tesla’s Autopilot feature.
In September, the NTSB determined that while the technology played a major role in the May 2016 fatal crash in Florida, the blame fell on driver errors, including overreliance on technology by an inattentive Tesla driver.
The California driver said the Autopilot mode was engaged when the car struck the firetruck while traveling 104 kilometers per hour (65 mph). “Amazingly there were no injuries! Please stay alert while driving!,” the Culver City firefighters union said in a tweet.
Tesla wouldn’t say if Autopilot was working at the time of the Culver City crash, but said in a statement Monday that drivers must stay attentive when it’s in use. The company would not comment on the investigation.

Apple’s next major update of its mobile software will include an option that will enable owners of older iPhones to turn off a feature that slows the device to prevent aging batteries from shutting down.
The free upgrade announced Wednesday will be released this spring.
The additional controls are meant to appease iPhone owners outraged since Apple acknowledged last month that its recent software updates had been secretly slowing down older iPhones when their batteries weakened.
Many people believed Apple was purposefully undermining the performance of older iPhones to drive sales of its newer and more expensive devices. Apple insisted it was simply trying to extend the lives of older iPhones, but issued an apology last month and promised to replace batteries in affected devices at a discounted price of $50.
Despite Apple’s contrition, the company is still facing an investigation by French authorities, a series of questions from U.S. Senate and a spate of consumer lawsuits alleging misconduct.
Besides giving people more control over the operation of older iPhones, the upcoming update dubbed iOS 11.3 will also show how well the device’s battery is holding up. Apple had promised to add a battery gauge when it apologized to consumers last month.
Other features coming in the next update will include the ability to look at personal medical histories in Apple’s health app, more tricks in its augmented reality toolkit and more animated emojis that work with the facial recognition technology in the iPhone X.

The International Telecommunication Union reports hundreds of millions of people in the world’s poorest countries now have access to the Internet and mobile devices.
It is increasingly difficult to function in this modern digital world without access to the Internet, a smart phone or other digital device. A new report by the International Telecommunication Union finds e-banking, e-commerce and other actions in cyberspace are no longer just the purview of the rich world.
It says all 47 of the world’s Least Developed Countries are making huge strides in increasing their Internet access. The ITU says more than 60 percent of LDC populations are covered by a 3G network, referring to a third generation or advanced wireless mobile telecommunication technology.
It notes by the end of last year, about 700 million people in LDCs had subscriptions to mobile phones, with 80 percent of their populations living within range of a mobile cellular network. Given this progress, the ITU reports LDCs are on track toward achieving the U.N. Sustainable Development Goal on universal and affordable Internet access by 2020.
ITU spokeswoman Jennifer Ferguson-Mitchell tells VOA having access to the Internet and mobile phones has a positive impact on peoples’ lives. She says digital connectivity can provide valuable knowledge and information to populations around the world.
“It gives farmers access to information on crops, when to plant their crops, weather patterns that are happening. It provides access to online education to communities,” she said. “It can make micro and small and medium sized enterprises be able to compete with larger businesses.”
The lTU says universal and affordable Internet access can help LDCs leap-frog in areas such as education, health, government services, trade and can trigger new business opportunities. While this is positive, the report identifies lack of digital skills as a key barrier to Information Communication Technology and Internet use in LDCs.
The report calls on policy makers, industry leaders, and educators to work together to increase digital skills across the Least Developed Countries.

Virtual reality allows the user to enter a different world through sight and sound. Several researchers and companies are adding a third element to the virtual experience: the sense of touch.
Researchers in haptics, meaning the feeling of touch, are incorporating this sense into virtual reality with real-world applications.
French company Go Touch VR created a device called VRtouch that straps onto the fingertips. The device applies varying pressure to the fingertips that correlates to what the user is seeing, touching and lifting in the virtual world.
“That will open enormous possibilities,” said Eric Vezzoli, co-founder of Go Touch VR.
Applications for the touch device include allowing users to undergo training in a safe virtual environment.
WATCH: Virtual reality with touch
Vezzoli said strapping three of the VR touch devices on each hand — the thumb, forefinger and middle finger — are ideal.
“We can use up to six fingers. Why? Because three fingers are enough to manipulate light objects. For example, if you’re writing, you use just three fingers. But (in) VR, there’s no mass, there’s no weight. So, just three fingers is just enough,” Vezzoli said.
Training in virtual reality with the sense of touch may include surgical preparation in a medical procedure or learning in an industrial setting. A different application can be found in the advertising world.
“You can, for example, visit an apartment — virtual apartment. You can open a cabinet. You can touch the bed — feel its softness, and that generates a physical connection with the buyer that can increase the chance of sale,” said Vezzoli.
The company’s clients include the carmaker BMW. Go Touch VR hopes its haptic device will interest content producers, major corporations and the military, as virtual reality is more widely used in the real world.

Seven years ago, a computer beat two human quizmasters on a Jeopardy challenge. Ever since, the tech industry has been training its machines even harder to make them better at amassing knowledge and answering questions.
And it’s worked, at least up to a point. Just don’t expect artificial intelligence to spit out a literary analysis of Leo Tolstoy’s War and Peace any time soon.
Research teams at Microsoft and Chinese tech company Alibaba reached what they described as a milestone earlier this month when their AI systems outperformed the estimated human score on a reading comprehension test. It was the latest demonstration of rapid advances that have improved search engines and voice assistants and that are finding broader applications in health care and other fields.
The answers they got wrong — and the test itself — also highlight the limitations of computer intelligence and the difficulty of comparing it directly to human intelligence.
Error! Error!
“We are still a long way from computers being able to read and comprehend general text in the same way that humans can,” said Kevin Scott, Microsoft’s chief technology officer, in a LinkedIn post that also commended the achievement by the company’s Beijing-based researchers.
The test developed at Stanford University demonstrated that, in at least some circumstances, computers can beat humans at quickly “reading” hundreds of Wikipedia entries and coming up with accurate answers to questions about Genghis Khan’s reign or the Apollo space program.
The computers, however, also made mistakes that many people wouldn’t have.
Microsoft, for instance, fumbled an easy football question about which member of the NFL’s Carolina Panthers got the most interceptions in the 2015 season (the correct answer was Kurt Coleman, not Josh Norman). A person’s careful reading of the Wikipedia passage would have discovered the right answer, but the computer tripped up on the word “most” and didn’t understand that seven is bigger than four.
“You need some very simple reasoning here, but the machine cannot get it,” said Jianfeng Gao, of Microsoft’s AI research division.
Human vs. machine
It’s not uncommon for machine-learning competitions to pit the cognitive abilities of computers against humans. Machines first bested people in an image-recognition competition in 2015 and a speech recognition competition last year, although they’re still easily tricked. Computers have also vanquished humans at chess, Pac-Man and the strategy game Go.
And since IBM’s Jeopardy victory in 2011, the tech industry has shifted its efforts to data-intensive methods that seek to not just find factoids, but better comprehend the meaning of multi-sentence passages.
Like the other tests, the Stanford Question Answering Dataset, nicknamed Squad, attracted a rivalry among research institutions and tech firms — with Google, Facebook, Tencent, Samsung and Salesforce also giving it a try.
“Academics love competitions,” said Pranav Rajpurkar, the Stanford doctoral student who helped develop the test. “All these companies and institutions are trying to establish themselves as the leader in AI.”
Limits of understanding
The tech industry’s collection and digitization of huge troves of data, combined with new sets of algorithms and more powerful computing, has helped inject new energy into a machine-learning field that’s been around for more than half a century. But computers are still “far off” from truly understanding what they’re reading, said Michael Littman, a Brown University computer science professor who has tasked computers to solve crossword puzzles.
Computers are getting better at the statistical intuition that allows them to scan text and find what seems relevant, but they still struggle with the logical reasoning that comes naturally to people. (And they are often hopeless when it comes to deciphering the subtle wink-and-nod trickery of a clever puzzle.) Many of the common ways of measuring artificial intelligence are in some ways teaching to the test, Littman said.
“It strikes me for the kind of problem that they’re solving that it’s not possible to do better than people, because people are defining what’s correct,” Littman said of the Stanford benchmark. “The impressive thing here is they met human performance, not that they’ve exceeded it.”

It seems like a game everyone wins: Some of China’s biggest tech companies, looking to hook in new consumers, are using cash prizes to draw millions of contenders to mobile-based online quiz shows.
Up to 6 million people at a time log into the free, live games on their smartphones to answer a series of rapid-fire questions in an elimination battle, with those remaining sharing the prize money.
Over the weekend, search engine giant Baidu and video game maker NetEase launched their own online shows, joining news feed platform Toutiao, Alibaba Group Holding Ltd-owned UCWeb and Wang Sicong, the scion of Chinese billionaire Wang Jianlin.
But how they will cash in on the games and stay on the right side of government censors might prove to be a tricky question.
The trivia games have drawn some controversy, heightened by a broader crackdown on online content during the last year under President Xi Jinping, from livestreams and blogs to a campaign against internet addiction.
This month, one quiz show, “Millions Winner,” backed by internet security company Qihoo 360, apologized after it was chastised by a regulator for listing Taiwan and Hong Kong, over which China claims sovereignty, as independent countries in a question.
How firms will monetize the craze is also not yet clear, though some companies, such as online retailer JD.com, have already jumped on the trend, sponsoring shows to help raise their profiles. Many of the games show ads to players during the shows.
“If you ask me why I do this, to be honest, I don’t really know if I can make money,” Zhou Hongyi, chairman of Qihoo, said at an event where he presented a contestant with a 1 million yuan ($156,115.84) prize check two weeks ago. “But from a user’s perspective, I think this is really fun.”
The quiz mania underlines the fierce appetite of China’s consumers for internet entertainment, a trend helping drive billions of dollars of investment into digital news portals, online gaming, internet advertising and television content.
“I heard about this game from a friend who won 1,700 yuan in one day. I immediately decided to join up myself,” Wang Ting, a 26-year-old graduate student in Qingdao, told Reuters. She now spends three hours each day on her phone playing the games.
Uncertain future
Questions, read by a live host, might include: “From which country were pineapples imported to China in the 16th century?” “In which dynasty was the lamb hot pot invented?” or “How many fingers does Mickey Mouse have?”
Contestants get 10 seconds — a time frame designed cut out cheating — to select the correct answer from a choice of three.
Winnings can be up to 3 million yuan per game, but are often split between many winners.
Toutiao parent Bytedance said that “millions of our users” had taken part in its live quiz “Million Dollar Hero” since the show launched at the start of January. It also has a tougher “Hero Game” with harder questions and bigger prizes.
“We’ve been running for just two weeks, so it’s still in the very early stages, but it’s encouraging to see how the game has taken off across the country, and with all age groups,” the company said in a statement to Reuters.
Toutiao, a highly popular news feed app, was valued at around $20 billion in a fundraising last year, sources close to the company told Reuters.
Raymond Wang, managing partner at Beijing law firm Anli Partners, said the shows were a “relatively low-cost way to get to users,” but cautioned there were political and technical risks.
Wang Ran, a prominent investor and head of Beijing-based private investment bank CEC Capital Group, posed a question on his WeChat account about the future of the online quiz show trend.
“A) Growing numbers will jump into the market. B) Someone will win 10 million yuan in one go. C) Authorities will strictly crack down on it. 10 seconds. Go!”

Facebook took a hard look in the mirror with a post Monday questioning the impact of social media on democracies worldwide and saying it has a “moral duty” to understand how it is being used.
Over the past 18 months, the company has faced growing criticism for its limited understanding of how misinformation campaigns and governments are using its service to suppress democracy and make people afraid to speak out.
“I wish I could guarantee that the positives are destined to outweigh the negatives, but I can’t,” wrote Samidh Chakrabarti, Facebook’s product manager of civic engagement.
Since the 2016 U.S. presidential election, Facebook has been looking more critically at how it is being used. Some of what it found raises questions about company’s long-standing position that social media is a force for good in people’s lives.
In December, in a post titled “Is Spending Time on Social Media Bad for Us?” the company wrote about its potential negative effects on people.
The self-criticism campaign extended to Facebook CEO Mark Zuckerberg’s personal goals. Each year he publicly resolves to reach one personal goal, which in the past included learning Mandarin, reading more books and running a mile every day.
This year, Zuckerberg said his goal is to fix some of the tough issues facing Facebook, including “defending against interference by nation states.”
Foreign Interference
During the 2016 U.S. election, Russian-based organizations were able to reach 126 million people in the U.S. with 80,000 posts, essentially using social media as “an information weapon,” wrote Chakrabarti. The company made a series of changes to make politics on its site more transparent, he wrote.
False News
Facebook is trying to combat misinformation campaigns by making it easier to report fake news and to provide more context to the news sources people see on Facebook.
“Even with these countermeasures, the battle will never end,” Chakrabarti wrote.
One of the harder problems to tackle, he said, are so-called “filter bubbles,” people only seeing news and opinion pieces from one point of view. Critics say some social media sites show people only stories they are likely to agree with, which polarizes public opinion.
One obvious solution – showing people the opposite point of view – doesn’t necessarily work, he wrote. Seeing contrarian articles makes people dig in even more to their point of view and create more polarizations, according to many social scientists, Chakrabarti said.
A different approach is showing people additional articles related to the one they are reading.
Reaction to Facebook’s introspection was mixed with some praising the company for looking at its blind spots. But not everyone applauded.
“Facebook is seriously asking this question years too late,” tweeted Jillian York, director for international freedom of expression for the Electronic Frontier Foundation.
