Silicon valley & technology news. Technology is the application of conceptual knowledge to achieve practical goals, especially in a reproducible way. The word technology can also mean the products resulting from such efforts, including both tangible tools such as utensils or machines, and intangible ones such as software. Technology plays a critical role in science, engineering, and everyday life

Twitter Doubles Character Limit to 280 for (Nearly) Everyone

Twitter says it’s ending its iconic 140-character limit — and giving nearly everyone 280 characters.

 

Users tweeting in Chinese, Japanese and Korean will still have the original limit. That’s because writing in those languages uses fewer characters.

 

The company says 9 percent of tweets written in English hit the 140-character limit. People end up spending more time editing tweets or don’t send them out at all. Twitter hopes that the expanded limit will get more people tweeting more, helping its lackluster user growth. Twitter has been testing the new limit for weeks and is starting to roll it out Tuesday.

 

The company has been slowly easing restrictions to let people cram more characters into a tweet. It stopped counting polls, photos, videos and other things toward the limit. Even before it did so, users found creative ways to get around the limit. This includes multi-part tweets and screenshots of blocks of text.

 

Twitter’s character limit was created so that tweets could fit into a single text message, back when many people were using texts to receive tweets. But now, most people use Twitter through its mobile app; the 140-character limit is no longer a technical constraint but nostalgia.

In Silicon Valley, the Homeless Illustrate a Growing Divide

In the same affluent, suburban city where Google built its headquarters, Tes Saldana lives in a crowded but tidy camper she parks on the street.

She concedes it’s “not a very nice living situation,” but it also is not unusual. Until authorities told them to move, more than a dozen other RVs filled with people who can’t afford rent joined Saldana on a tree-lined street in Mountain View, parked between a Target and a luxury apartment complex.

Homeless advocates and city officials say it’s outrageous that in the shadow of a booming tech economy – where young millionaires dine on $15 wood-grilled avocado and think nothing of paying $1,000 for an iPhone X – thousands of families can’t afford a home. Many of the homeless work regular jobs, in some cases serving the very people whose sky-high net worth is the reason housing has become unaffordable for so many.

Across the street from Saldana’s camper, for example, two-bedroom units in the apartment complex start at $3,840, including concierge service. That’s more than she brings home, even in a good month.

Saldana and her three adult sons, who live with her, have looked for less rustic accommodations, but rents are $3,000 a month or more, and most of the available housing is distant. She said it makes more sense to stay in the camper near their jobs and try to save for a brighter future, even if a recent city crackdown chased them from their parking spot.

“We still need to eat,” said Saldana, 51. “I still want to bring my kids, once in a while, to a movie, to eat out.”

She cooks and serves food at two hotels in nearby Palo Alto, jobs that keep her going most days from 5 in the morning until 10 at night. Two of her sons, all in their 20s, work at a bakery and pay $700 toward the RV each month. They’re all very much aware of the economic disparity in Silicon Valley.

“How about for us people who are serving these tech people?” Saldana said. “We don’t get the same paycheck that they do.”

It’s all part of a growing crisis along the West Coast, where many cities and counties have seen a surge in the number of people living on the streets over the past two years. Counts taken earlier this year show 168,000 homeless people in California, Oregon and Washington – 20,000 more than were counted just two years ago.

The booming economy, fueled by the tech sector, and decades of under-building have led to an historic shortage of affordable housing. It has upended the stereotypical view of people out on the streets as unemployed: They are retail clerks, plumbers, janitors – even teachers – who go to work, sleep where they can and buy gym memberships for a place to shower.

The surge in homelessness has prompted at least 10 local governments along the West Coast to declare states of emergency, and cities from San Diego to Seattle are struggling to come up with immediate and long-range solutions.

San Francisco is well-known for homeless tent encampments. But the homeless problem has now spread throughout Silicon Valley, where the disparity between the rich and everyone else is glaring.

There is no firm estimate on the number of people who live in vehicles in Silicon Valley, but the problem is pervasive and apparent to anyone who sees RVs lining thoroughfares; not as visible are the cars tucked away at night in parking lots. Advocates for the homeless say it will only get worse unless more affordable housing is built.

The median rent in the San Jose metro area is $3,500 a month, yet the median wage is $12 an hour in food service and $19 an hour in health care support, an amount that won’t even cover housing costs. The minimum annual salary needed to live comfortably in San Jose is $87,000, according to a study by personal finance website GoBankingRates.

So dilapidated RVs line the eastern edge of Stanford University in Palo Alto, and officials in neighboring Mountain View have mapped out more than a dozen areas where campers tend to cluster, some of them about a mile from Google headquarters.

On a recent evening, Benito Hernandez returned to a crammed RV in Mountain View after laying flagstones for a home in Atherton, where Zillow pegs the median value of a house at $6.5 million. He rents the RV for $1,000 a month and lives there with his pregnant wife and children.

The family was evicted two years ago from an apartment where the rent kept going up, nearing $3,000 a month.

“After that, I lost everything,” said Hernandez, 33, who works as a landscaper and roofer.

He says his wife “is a little bit sad because she says, ‘You’re working very hard but don’t have credit to get an apartment.’ I tell her, ‘Just wait, maybe a half-year more, and I’ll get my credit back.'”

The plight of the Hernandez family points out one of the confounding problems of the homeless surge along the West Coast.

“This is not a crisis of unemployment that’s leading to poverty around here,” said Tom Myers, executive director of Community Services Agency, a nonprofit based in Mountain View. “People are working.”

Mountain View, a city of 80,000 which also is home to Mozilla and 23andMe, has committed more than $1 million over two years for homeless services, including money for an outreach case manager and a police officer to help people who live in vehicles. At last count, there were people living in more than 330 vehicles throughout the city.

Mayor Ken Rosenberg is proud of the city’s response to the crisis – focusing not on penalties but on providing services. Yet he’s also worried that the peace won’t last as RVs crowd into bike lanes and over-taxed streets.

Last week, Mountain View officials posted signs banning vehicles more than 6 feet high on some parts of the street where Saldana, Hernandez and others living in RVs were parked, saying they were creating a traffic hazard. The average RV is well over that height.

That follows similar moves over the summer by Palo Alto, which started cracking down on RVs and other vehicles that exceed the 72-hour limit on a busy stretch of El Camino Real.

In San Jose, officials recently approved an ordinance pushed by an interfaith group called the Winter Faith Collaborative to allow places of assembly – including gyms and churches – to shelter homeless people year-round.

Ellen Tara James-Penney, a 54-year-old lecturer at San Jose State University, parks her old Volvo at one of those safe haven churches, Grace Baptist Church, and eats in its dining hall. She is paid $28,000 a year to teach four English classes and is carrying $143,000 in student debt after earning two degrees.

She grades papers and prepares lessons in the Volvo. At night, she leans back the driver’s seat and prepares for sleep, one of two dogs, Hank, by her side. Her husband, Jim, who is too tall for the car, sleeps outside in a tent cot with their other dog, Buddy.

The Bay Area native remembers the time a class was studying John Steinbeck, when another student said that she was sick of hearing about the homeless.

“And I said, ‘Watch your mouth. You’re looking at one.’ Then you could have heard a pin drop,” she said. “It’s quite easy to judge when you have a house to live in or you have meds when you’re depressed and health care.”

In response to growing wealth inequities, unions, civil rights groups and community organizations formed Silicon Valley Rising about three years ago. They demand better pay and benefits for the low-income earners who make the region run.

SEIU United Service Workers West, for example, organized roughly 3,000 security guards who work for companies that contract with Facebook, Google and Caltrain, the mass transit system that connects Silicon Valley with San Francisco.

One of those workers is Albert Brown III, a 46-year-old security officer who recently signed a lease for half of a $3,400 two-bedroom unit in Half Moon Bay, about 13 miles from his job.

He can barely afford the rent on his $16-an-hour salary, even with overtime, but the car that doubled as his home needed a pricey repair and he found a landlord willing to overlook his lousy credit. Still, Brown worries he won’t be able to keep up with his payments.

His feet have been hurting. What if a doctor tells him to rest for a few days or a week?

“I can’t miss a minute. If I miss a minute or a shift? No way, man. A week? Forget it, it’s over. It’s all downhill from there,” he said.

“It’s a sad choice. I have to decide whether to be homeless or penniless, right?”

Indonesia Threatens to Block WhatsApp Messaging Over Obscene Content

Indonesia on Monday vowed to block Facebook’s WhatsApp Messenger within 48 hours if the service did not ensure that obscene Graphics Interchange Format (GIF) images were removed.

WhatsApp, which is widely used in Indonesia, the world’s most populous Muslim-majority nation, said message encryption prevented it from monitoring the animated graphics files, known as GIFs, that are available on the app through third-party services.

WhatsApp said in a statement on Monday that it asked the government instead to work with those providers, which integrate their technology into WhatsApp to allow users to enter keywords to search for GIFs.

Indonesia’s internet is partly censored, with access blocked to websites providing criticism of Islam, dating services and sex education, according to research published in May by Tor Project, a nonprofit maker of Web browsing tools.

Semuel Pangerapan, a director general at Indonesia’s communications and informatics ministry, said WhatsApp would be blocked within 48 hours unless the images supplied by third parties were taken off the service.

“Yes, true. They have to follow the rules of the host,” Pangerapan said of the proposed block.

The ministry had sent three letters to WhatsApp over the issue, he said.

“They have responded, but asked us to speak directly to the third party. The GIFs appeared in their apps. Why do we have to be the one speaking to the third party? They are supposed to be the ones managing it,” said Pangerapan.

Third party responds

Tenor Inc, one of the third parties, said it was attempting to release a “fix.” Giphy, another provider, did not respond to requests to comment.

Jennifer Kutz, a Tenor spokesperson, said in a statement that the company is working “to address the content issues raised by the Indonesian government within the next 48 hours.”

Kutz said the company “regularly” works with “local entities to make sure our content reflects the cultural mores and legal requirements.”

She declined to identify the proposed fix or existing regions with content restrictions. Tenor allows integrators of its service to block potentially objectionable image results or a defined list of search terms.

“In the case of WhatsApp, we’re taking on this responsibility,” Kutz said in an email.

Giphy, a New York City company that also works with WhatsApp, offers its partners a feature for filtering inappropriate images.

Indonesia’s warning did not appear to target Gboard, a keyboard app developed by Google that provides comparable GIF search results but must be installed separately from WhatsApp on most devices.

Past battles

Indonesia had 69 million monthly active Facebook users as of the first quarter of 2014, ranking the country fourth globally after the United States, India and Brazil, company data showed.

Some reaction on Indonesian social media to the threatened block was skeptical.

“While you’re at it, why don’t you block Twitter too, (and) if necessary all browsers in the Playstore, because it’s way easier to search for porn there than on WhatsApp,” wrote one Twitter user, with the handle @jnessy.

The country’s regulators have reached settlements with several technology companies after threatening to shut them down. In August, Indonesia announced it would block Giphy’s website for showing gambling-related ads. Access soon was restored after it agreed to cooperate with regulators.

Bans similarly were rescinded in recent years on social media websites such as Vimeo and Tumblr and the chat app Telegram, which regulators had said was “full of radicals and terrorist propaganda.”

The Indonesian Consumers Foundation (YLKI) had urged the communications ministry to block pornographic GIF images accessible via emoticons, complaining that children could easily reach them, according to news website kompas.com. Terms of use for WhatsApp, Tenor and Giphy say users must be 13 years old.

Snapchat Outage Prompts Complaints on Twitter

Snapchat faced a worldwide outage for at least four hours on Monday, prompting a flood of complaints on rival mobile application Twitter a day before posting its third quarterly earnings as a public company.

“We’re aware of the issue and working on a fix,” Snapchat said on its support Twitter account, recommending that users stay logged on. 

Many users tweeted about being unable to sign on after logging off the app, which is popular among people under 30 for posting pictures that are automatically deleted within 24 hours.

Twitter user @bradleykeegan11 wrote, “(Snapchat)Won’t let me log in and keeps saying ‘could not connect’.”

A spokesman for the Snap Inc unit did not immediately respond to a query about the size and cause of the outage.

Snapchat had at least a couple of technical issues in October, according to its Twitter support page.

Snap, which went public in May, is scheduled to report third quarter earnings on Tuesday. Its stock closed down 2.8 percent at $14.83 on Monday, below its initial public offering price of $17.

Stephen Hawking Says Technology Could End Poverty But Urges Caution

Technology can hopefully reverse some of the harm caused to the planet by  industrialisation and help end disease and poverty, but artificial intelligence (AI) needs to be controlled, physicist Stephen Hawking said on Monday.

Hawking, a British cosmologist who was diagnosed with motor neuron disease aged 21, said technology could transform every aspect of life but cautioned that artificial intelligence poses new challenges.

He said artificial intelligence and robots are already threatening millions of jobs — but this new revolution could be used to help society and for the good of the world such as alleviating poverty and disease.

“The rise of AI could be the worst or the best thing that has happened for humanity,” Hawking said via telepresence at opening night of the 2017 Web Summit in Lisbon that is attended by about 60,000 people.

“We simply need to be aware of the dangers, identify them, employ the best possible practice and management and prepare for its consequences well in advance.”

Hawking’s comments come during an escalating debate about the pro and cons of artificial intelligence, a term used to describe machines with a computer code that learns as it goes.

Silicon Valley entrepreneur Elon Musk, who is chief executive of electric car maker Tesla Inc and rocket company SpaceX, has warned that AI is a threat to humankind’s existence.

But Microsoft co-founder Bill Gates, in a rare interview recently, told the WSJ Magazine that there was nothing to panic about.

Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

“We need to take learning beyond a theoretical discussion of how AI should be, and take action to make sure we plan for how it can be,” said Hawking, who communicates via a cheek muscle linked to a sensor and computerized voice system.

“You all have the potential to push the boundaries of what is accepted, or expected, and to think big. We stand on the threshold of a brave new world. It is an exciting — if precarious — place to be and you are the pioneers,” he said.

 

 

Supreme Court Rejects Samsung Appeal in Apple Patents Case

The Supreme Court has rejected Samsung’s appeal of court rulings that it impermissibly copied features of Apple’s iPhone.

The justices on Monday left in place rulings in favor of Apple involving its patents for smartphone features that include auto-correct and a slide that unlocks the device.

In 2014, a jury awarded Apple $120 million in damages for Samsung’s infringement of the patents.

The case is part of a series of disputes between the technology rivals that began in 2011. Last year, the high court ruled in favor of Samsung in a legal fight over the similar appearances of the two companies’ smartphones.

Will Formula Racing Switch to Electric Cars?

As private and public transportation slowly shifts to electric propulsion, fans of Formula One car racing wonder whether the thrill of roaring turbocharged engines and the smell of burning car tires will someday be replaced by the subdued sleep-inducing whine of electric motors. But Formula E cars keep gathering fans and creating support for alternative power sources. VOA’s George Putic reports.

Old Tech Increasingly Causing Health, Environmental Troubles

A growing amount of the waste in the world is out-of-date electronics. And inside all of our devices are a lot of valuable metals, and also some dangerously toxic ones.

Afghanistan Blocks Social Media Services

Authorities in Afghanistan are temporarily blocking WhatsApp and Telegram social media services in the country, citing security concerns, officials confirmed Friday.

An official at the Afghan Telecommunications Regulatory Authority, ATRA, told VOA the social media tools will be suspended for 20 days. The decision follows a request from state security institutions.

The official, who spoke on condition of anonymity, said a formal announcement is expected Saturday.

ATRA has ordered telecom companies to shut down the services November 1, according to a copy of official instructions appearing in Afghan media.

Social media users have complained of technical problems while using the two services in recent days.

The controversial move has sparked criticism of the Afghan government, and it is being slammed as an illegal act and an attack on freedom of expression.

The outage prompted the telecom regulator to issue a statement Friday, saying the ban is meant to test “a new kind of technology” in the wake of users’ complaints.

It went on to defend the restriction, saying WhatsApp and Telegram are merely voice and messaging services and their temporary suspension does not violate the civil rights of Afghans. The government is committed to freedom of expression, the ministry added.

Afghan journalists and activists on Twitter dismissed the statement.

“This seems to be the beginning of government censorship. If it’s not resisted soon the gov’t will block FB & twitter,” wrote Habib Khan Totakhil on Twitter.

“Gov’t fails to deliver security, now it seeks to hide its incompetence by imposing ban on messaging platforms. Totalitarianism?,” said the Afghan journalist.

“#Censorship is against what freedom we stood for in #Afghanistan post 2001. Gains shouldn’t go to waste,” tweeted activist Nasrat Khalid.

An estimated 6 million people in war-torn Afghanistan can access internet-based services. The growth of media and social media activism have been among the few success stories Afghanistan has seen in the post-Taliban era.

Classifying numbers

The restrictions on social media come as the Taliban intensifies attacks on Afghan security forces, inflicting heavy casualties.

The insurgent group also relies heavily on WhatsApp, Telegram, Twitter and Facebook to publicize its battlefield gains.

The Afghan government has lately barred the United States military from releasing casualty numbers, force strength, operation readiness, attrition figures and performance assessments of the Afghan National Defense and Security Forces.

The U.S. Special Inspector General for Afghanistan Reconstruction, John Sopko, while briefing members of Congress on Wednesday, severely criticized the classification move. He maintained American taxpayers have a right to know how their money is being spent.

“The Taliban know this [Afghan casualties], they know who was killed. They know all about that. The Afghans know about it, the U.S. military knows about it. The only people who wouldn’t know are the [American] people who are paying for it,” Sopko noted.

The United States has spent nearly $120 billion on reconstruction programs in Afghanistan since 2002. More than 60 percent of the money has been used to build Afghan security forces.

Researchers Working for the End of the Internal Combustion Automobile

Twitter Employee, on Last Day, Deactivates Trump Account

U.S. President Donald Trump’s @realdonaldtrump Twitter account was deactivated by a Twitter Inc employee whose last day at the company was Thursday, and the account was down for 11 minutes before it was restored, the social media company said.

“We have learned that this was done by a Twitter customer-support employee who did this on the employee’s last day. We are conducting a full internal review,” Twitter said in a tweet.

“We are continuing to investigate and are taking steps to prevent this from happening again,” the company said in an earlier tweet.

A Twitter representative declined to comment further.

The White House did not respond immediately to a request for comment.

Trump has made extensive use of messages on Twitter to attack his opponents and promote his policies both during the 2016 presidential campaign and since taking office in January.

He has 41.7 million followers on Twitter.

His first tweet after Thursday’s outage:

In a similar incident last November, Twitter Chief Executive Officer Jack Dorsey’s account was briefly suspended as a result of what he said was an internal mistake.

Malaysia Investigating Reported Leak of 46 Million Mobile Users Data

Malaysia is investigating an alleged attempt to sell the data of more than 46 million mobile phone subscribers online after a major data breach, Communications and Multimedia Minister Salleh Said Keruak said on Wednesday.

The massive data breach was first reported last month by Lowyat.net, a local technology news website, which said it had received a tip-off that someone was trying to sell huge databases of personal information on its forums.

Salleh said the country’s internet regulator, the Malaysian Communications and Multimedia Commission (MCMC), was looking into the matter with the police.

“We have identified several potential sources of the leak and we should be able to complete the probe soon,” Salleh told reporters at parliament.

The leaked data was being sold for an undisclosed amount of Bitcoin, a digital currency, Lowyat.net said on Monday.

It included lists of mobile phone numbers, identification card numbers, home addresses, and SIM card data of 46.2 million customers from at least 12 Malaysian mobile phone operators.

Malaysia’s population is just around 32 million, but many have several mobile numbers. The lists are also believed to include inactive numbers and temporary ones bought by visiting foreigners, local daily The Star reported.

MCMC’s chief operating officer Mazlan Ismail said on Tuesday the regulator had met with local telecommunications companies to seek their cooperation in the probe, according to state news agency Bernama.

The data also includes private information of more than 80,000 individuals leaked from the records of the Malaysian Medical Council, the Malaysian Medical Association, and the Malaysian Dental Association, Lowyat.net said.

New Fingerprint Technology Solves Mysteries, Brings Closure to Families of Deceased

But a new FBI database aims to share as much information despite the few clues available. Arash Arabasadi reports.

US Social Media Giants Pledge to Combat Foreign Disinformation

Attorneys for Twitter, Facebook and Google on Tuesday told U.S. lawmakers that Russian entities used their platforms to sow discord and disinformation during the 2016 U.S. presidential campaign, but downplayed the magnitude of those efforts.

“Foreign actors used fake accounts to place ads in Facebook and Instagram that reached millions of Americans over a two-year period,” Facebook General Counsel Colin Stretch said, testifying before a Senate Judiciary subcommittee. “Many of these ads and posts are inflammatory. Some are downright offensive.”

Sean Edgett, Twitter’s acting general counsel, said the company studied all tweets posted from Sept. 1 to Nov. 15, 2016, and found that election-related content posted by automated Russian troll accounts “was comparatively small.” He said the Russian troll accounts made up “around 1/100th of a percent of total Twitter accounts” during the time studied.

“Twitter believes that any activity of that kind — regardless of magnitude — is unacceptable and we agree we must do better to prevent it,” he said.

Twitter has taken action against the suspected Russian trolls, suspending 2,752 accounts and implementing new dedicated teams “to enhance the quality of the information our users see,” Edgett said.

Facebook, meanwhile, said it would hire more people to vet and, when necessary, remove content, and verify and publish the identities of election advertisers.

Watch: Social media companies to fight disinformation

Bipartisan legislation has been introduced in the Senate requiring some of the very steps technology giants say they are implementing on their own.

“These platforms are being used by people who wish us harm and wish to undercut our way of life,” said Republican Senator Lindsey Graham of South Carolina.

“It shouldn’t be news to anyone that Russia interfered in the election,” said California Democratic Senator Dianne Feinstein. “What is really staggering and hard to fully comprehend is how easily and successfully they turned modern technologies to their advantage.”

The social media attorneys said Russian trolling campaigns consistently sought to rile up Americans, first in a way damaging to Democratic presidential nominee Hillary Clinton. After the election, they said, Russian efforts appeared aimed at sowing doubts about the legitimacy of Republican Donald Trump’s victory at the polls — a point seized upon by Republican Senator Chuck Grassley of Iowa.

“Russia does not have loyalty to a political party in the United States; their goal is to divide us and discredit our democracy,” Grassley said.

Representatives from the same social media companies testify Wednesday before the House and Senate Intelligence Committees.

Vietnam Tech Startups Seek Next Phase

There’s a short but not-so-simple question facing Vietnam’s technology startup fans: Now, what?

The communist country was not immune to the startup craze that swept the globe, but much of the early period was spent talking about tech and all the local potential. In what could be called the next phase of the craze, Vietnam now hopes to go beyond just talking. The focus now is on getting entrepreneurs to deliver on their pitches and meet concrete benchmarks, whether that’s to turn a profit, expand overseas, or find “exits” for their businesses, such as through acquisitions.

At a basic level, Vietnam has what’s needed to be a place prime for startups. Citizens have high literacy rates and math proficiency, which eases the path to creating an army of programmers for the economy. The country also has a balance that combines, on the one hand, a large consumer market on par with those of Thailand and the Philippines, and on the other hand, a lower level of development with high growth rates on par with those of Laos and Cambodia. And the low cost of things like wages and Internet plans allows people to establish companies at minimal expense.

But these are only ingredients, not, so far, action toward a modern culture of enterprise.

“Vietnam usually does copy-paste,” said Lam Tran, CEO of the startup WisePass, adding that locals should move past the model of copying a business idea from a foreign country and pasting it into the domestic market. “We don’t know how to internationalize.”

WisePass, an app that connects monthly subscribers to bar and restaurant deals, launched in Ho Chi Minh City with plans to cover seven countries in the near future.

Taking advantage of cross-border ties is one effective, increasingly popular strategy, startup aficionados say. For one thing, Vietnam has a huge postwar diaspora, known as Viet Kieu, who help connect the Southeast Asian country to investors, advisers, and developers abroad. For another, the tech scene inside the border is more cosmopolitan than ever.

To give one example, the Vietnam Innovative Startup Accelerator (VIISA) has invested in 11 companies for the second batch of what it calls “graduates.” All have domestic links, but have partners operating in locales as disparate as Ukraine, South Korea and France.

Sangyeop Kang, investment officer at VIISA partner Hanwha Investment, said he’s “delighted about the diversity” of this sophomore batch.

“The foreign teams were able to expand their business in Vietnam, while helping Vietnamese companies with global insights,” Kang said. “This is a step forward for the ecosystem.”

In a sign of official interest, the government has a carve-out for startups in its Law on Supporting Small and Medium-Sized Enterprises, which will take effect Jan. 1. The law offers young companies support with co-working spaces, technical equipment, intellectual property training, and low interest rates, among other things.

To do more than copy and paste, new businesses are contemplating how to outfit themselves for Vietnam. The startup But Chi Mau, for instance, makes games that tap into the unquenchable thirst for education, while MarketOi deploys motorbike drivers to let customers customize their food deliveries.

“The question is how to differentiate ourselves,” MarketOi founder Germain Blanchet said, before proceeding to answer that question: “This is with flexibility.”

U. of Michigan Expert Puts Bird-like Robot Through Its Paces

A rare bird has landed at the University of Michigan: a two-legged robot named “Cassie” that researchers hope could be the forerunner of a machine that one day will aid search-and-rescue efforts.

 

Cassie — whose name is derived from the cassowary, a flightless bird similar to an ostrich — stands upright on legs with backward-facing knees. The biped that weighs about 66 pounds (29.94 kilograms) may not have feathers or a head, but she is attached to a short torso that holds motors, computers and batteries and is able to walk unassisted on rough and uneven terrain.

 

Cassie, which stands a bit over 3.25 feet (1 meter) at full leg extension, was built by Albany, Oregon-based Agility Robotics and purchased by Michigan researchers using grant money from the National Science Foundation and Toyota Research Institute. Although other institutions have acquired similar models, Michigan’s team is excited to use its version to put Michigan Robotics’ cutting-edge programming to the test, said Jessy Grizzle, director of Michigan Robotics.

“This stuff makes our old math look like child’s play,” Grizzle said.

 

Although there is considerable excitement about Cassie and the potential she represents, certain real-world applications are still a bit out of reach.

 

Search-and-rescue “is a hard problem and serves as a template for ‘unsolved problems in robotics,’ which is one of the reasons you see it pop up so much when robotics companies talk about applications,” said Agility Robotics CEO Damion Shelton, who added that it is “difficult to even speculate” when a robot could be used for such a purpose.

 

Other applications will be launched sooner, according to Shelton, who said a robot capable of walking around the perimeter of an industrial site taking 3-D scans is no more than two years away from becoming reality.

 

For now, Grizzle and some of his students are putting Cassie through her paces on and around Michigan’s Ann Arbor campus. During a recent a stroll on a pedestrian walkway, Cassie ambled on a grassy, sloped surface, then took a serious tumble and did a face-plant on the concrete.

 

“Well, I think that’s the end” of the test, Grizzle said, as Cassie lay in a heap on the ground, slightly nicked and scratched but no worse for wear.

 

The programs Grizzle and his students tested “are version 1.0,” he said.

 

“They are simple algorithms to make sure that we understand the robot. We will now focus on implementing our super-cool latest stuff,” Grizzle said.

World Economic Forum: Silicon Valley Must Stem IS Violent Content

The World Economic Forum’s human rights council report issued on Monday, warns that tech companies might risk tougher regulations by governments to limit freedom of speech if they do not stem the publishing of violent content by Islamic State and the spread of misinformation.

The report urged tech companies to employ thorough monitoring on their services, and “assume a more active self-governance rule,” recommending that tech firms must apply more rigorous rules.

This report comes before the three tech giants Facebook, Twitter and Google, testify before a U.S. congressional committee in November about using their platforms for spreading political misinformation during the 2016 presidential elections.

The use of tech platforms and tools has helped the Islamic State spread its agenda and attract recruits. Digital propaganda motivated more than 30,000 people to journey thousands of miles to join IS, according to a report published by Wired, a magazine published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics.

“ISIS’s supporters embraced new social media platforms and encrypted communications tools to compensate for law enforcement and platform owner actions against ISIS since June 2014,” the Institute for the Study of War said in its report “The Virtual  Caliphate.”

Silicon Valley tech companies convened last August with representatives from the tech industry, government and non-governmental organizations in the first Global Internet Forum to Counter Terrorism. The forum was formed by Facebook, Microsoft, Twitter and YouTube.

The meeting focused on how participating parties can cooperate to block the spread of terrorism and violent extremism using tech platforms and services.

In the past year, social media companies edited and updated their user guidelines to address such sensitive topics as extremism and terrorism, death, war and sexual abuse.

In August 2016, Twitter announced that it suspended 360,000 accounts for violating the company’s prohibition on violent threats and the promotion of terrorism. Twitter added that although there is no “one magic algorithm for identifying terrorist content on the internet, they will continue to utilize other forms of technology and expanded its partnerships with organizations working to counter violent extremism (CVE) online.”

Last August, Google’s YouTube announced joining efforts with more than 15 additional expert NGOs and institutions to help the company better identify content that is being used to radicalize and recruit extremists.

“We’ll soon be applying tougher treatment to videos that aren’t illegal but have been flagged by users as potential violations of our policies on hate speech and violent extremism,” YouTube said.

In a speech for the Global Coalition on March 22 in Washington D.C., Secretary of State Rex Tillerson said: “We must break ISIS’s ability to spread its message and recruit new followers online. A digital caliphate must not flourish in the place of a physical one.”

“We must fight ISIS online as aggressively as we would on the ground,” Tillerson said.

Radio Pollution Creates Space Shield for Satellites

People are big polluters, on the land, in the sea and even in outer space, that can include anything from a hammer that floats away from the space station, to radiation from a nuclear weapons test in the atmosphere.

“This can range from little chips of paint all the way up to spent rocket bodies and things like that,” said Dan Baker, director of the Laboratory of Atmosphere and Space Physics at the University of Colorado, Boulder. “We’ve been trying to figure out how can we most effectively eliminate this debris without causing more of a problem.”

Space debris travels so fast, even an orbiting chip of paint can poke a hole in a satellite. But Baker says something tinier, and natural, is a bigger hazard: It’s the highly charged “killer electrons” of the magnetized zone above the earth called The Van Allen Belts.

“We’ve observed them to cause very significant problems for spacecraft,” Baker said.

Electro-magnetic planetary blanket

The doughnut-shaped Van Allen Belts around our planet protect life on earth from solar winds and cosmic rays. But their highly energetic charged particles can damage the circuitry in space stations, weather satellites and other machines that travel through that region of space.

Baker notes that “killer electrons” can also come from some human activities, like the atmospheric testing of nuclear weapons.

“Back in the 1950s and especially in the 1960s, there were nuclear explosions that put huge amounts of radiation into space that caused many satellites to ‘die’ because of radiation damage,” he said. “And if that were to happen today, we know that there are over 1,400 satellites operating in space around the earth and all of those could be subject to very severe consequences.”

Most nations adhere to treaties that prohibit atmospheric weapon testing. But Baker says that’s no guarantee.

“What is worrisome to us from a political standpoint today is that there are nations, for example, North Korea and others, that may be thinking once again, and who may not be adherent to such treaties, that this might be an interesting way to mess with modern technology,” Baker said.

Mysterious space shield

Radiation particles in the Van Allen Belts already “mess” with modern technology. So when satellites must spend time in that region, they are built with thicker materials. That armor makes them heavier, and more expensive. Fortunately, spacecraft and satellites that orbit just under the Van Allen Belts don’t need this heavy shielding. Baker says that’s because, at the lower edge of the Van Allen Belts, the killer electrons abruptly stop.

He compares it to the shields that protected Captain Kirk’s ship, the Enterprise, from phasers and asteroids on Star Trek.

Scientists have known for years that something here on the earth creates an invisible bubble that clears killer electrons from the lower edge of the Van Allen Belts. Just what makes that shield has been a mystery.

But recently, Baker’s teams figured out its source. The “bubble maker” is very low frequency radio transmissions, also known as VLF. Militaries use VLF to communicate with submarines underwater. It turns out those radio waves also travel up, through the atmosphere, to the Van Allen Belts.

“So the VLF bubble is made up of these intense waves. These waves act to sort of scatter and scrub the inner part of the Van Allen Belts,” Baker said, admitting, “I would prefer that we not be messing with nature. However, in this particular case I would say that there is some evidence that this is beneficial.”

John Bonnell, a researcher at the University of California Berkeley’s Space Sciences Lab, agrees that VLF “pollution” is probably benign, and he points to the high-energy radiation emitted by lightning bolts as evidence.

“We’ve had natural clearing of the radiation Belts with lightning, for as long as we’ve had lightning. So in essence, you’ve had a long-running experiment that you can look at and say, ‘Well, if we’re going to do things on sort of a sporadic basis, whereas lightning’s been doing it daily for hundreds of millions of years, the likelihood of there being a bad side effect is pretty minimal,'” he said.

Bonnell says that discovering a man-made way to clear killer electrons from the Van Allen Belt does not mean we will soon create “shields up” devices that use magnetics or radio transmissions. At least, he says, we’re not making them yet.

“It’s a fascinating possibility and it’s a fascinating technology that could enable us in the future, to explore more of the solar system with people, with robots. And so it’s definitely something that people pick away at slowly over time,” he said.

Bonnell says scientists, engineers and astronomers have teamed up to make amazing discoveries about how to study, and travel through, outer space. And while the future shape of space exploration is a mystery, our new understanding about the man-made “pollution” that shields satellites may be an important part of it.
