Don’t want Amazon boxes sitting on the porch? The company hopes you’ll let a stranger inside to drop them off.  

Amazon said Wednesday it will launch a service called Amazon Key next month that will let people allow the door to be unlocked when they’re not there so packages can be left inside. 

The proposal drew plenty of humorous reactions on social media, as well as concerns about safety or delivery employees being mistaken for intruders. Amazon said the drivers would be well-vetted, while one expert said the company has built up trust with customers and younger customers were more likely to try it out.   

An in-home delivery program also falls in line with Amazon’s strategy of trying to make shopping with it so convenient that consumers don’t think about buying elsewhere. And with the option requiring a specific camera that it sells, the move helps Amazon tie customers even closer to its gadgets as well as the items it delivers. 

Customers who want to use the service would need to be Amazon Prime members and would have to buy a camera and a Wi-Fi-connected lock from the Seattle-based company that starts at $250. Shoppers will then be able to choose in-home delivery as an option in the Amazon app.

When the delivery person shows up, they will knock first and scan the package. Amazon will make sure the person is at the right home and unlock the door. No codes or keys are needed, and the indoor camera will record the in-home delivery. The Amazon Cloud Cam also lets users watch a livestream or recorded video on Amazon’s Fire tablet, Fire TV or its voice-activated Echo devices that have a video screen.

The service is likely to be more of a hit with younger families, said Timothy Carone, an associate teaching professor at University of Notre Dame’s Mendoza College of Business. He said millennials are already comfortable posting photos and their whereabouts on Facebook, Instagram and other social media.

“They’re less concerned about privacy than older generations are,” Carone said.

Walmart is testing a similar service in California’s Silicon Valley, which lets delivery people drop off packages or stock the fridge with groceries bought from Walmart.com. The delivery person is given a one-time code to open the door and Walmart said customers will get an alert on their smartphones when someone enters.

For Amazon, the in-home delivery service helps it enter the fast-growing home security camera market, competing with Google’s Nest cameras, said Martin Garner, a device and internet analyst at CCS Insight. Tying the camera in with the in-home delivery service gives people a reason to buy it, said Garner.

“They’ve been on a mission to do this,” said Garner.

Amazon.com Inc. said in-home delivery will be available Nov. 8 in 37 cities, including Atlanta, Cleveland and Denver. The company says the service is covered by the Amazon Key Happiness Guarantee, which applies to delivery issues, property damage or theft. And Amazon said the deliveries are carried out by drivers who are vetted with background checks and driving record reviews.

The company said the smart lock can also be used to let in out-of-town guests who want to make themselves at home. And in the coming months, it can be used to grant access to housekeepers to scrub the kitchen or dog walkers to take your furry friend for a stroll.

But for package deliveries, you may need to keep your dogs and cats a bit contained: Amazon doesn’t recommend using the in-home delivery service if pets can get to the front door on delivery day.

Facebook is partnering with a developer to build a wind power farm in northeast Nebraska that will supply energy for the company’s planned data center.

The social media giant announced last week that it has partnered with Trade Winds Energy to build the Rattlesnake Creek Wind Project in rural Dixon County.

Facebook plans to use energy from the wind farm to power its upcoming data center in Papillion, a suburb of Omaha. Of the 320 megawatts of power the wind farm will create, 200 of them will be allocated to the data center while the remaining will be available for other buyers.

 

Officials said the project will produce the second-largest wind farm in Nebraska, behind the 400-megawatt Grande Prairie project in Holt County. Officials also said the new wind farm will generate enough energy to power 90,000 homes.

 

Both projects are examples of the state’s rich wind resource being acknowledged, said David Bracht, director of the Nebraska Energy Office.

 

“The wind projects that have been installed [in Nebraska] have shown themselves to be very, very productive,” Bracht said.

 

A new electric rate structure rolled out in January by the Omaha Public Power District means Facebook can power its data center with 100 percent clean energy. The company also aims to get at least 50 percent of its total electricity consumption from clean and renewable energy sources in 2018.

 

Neither Facebook nor Trade Winds provided a timeline or cost for the wind farm.

A university engineering department has developed what amounts to a Tinder app for criminals — a computer program that matches inmates with suitable prisons.

The software, unique in the corrections field, has saved the Pennsylvania Department of Corrections about $3 million in its first year. It’s resulted in fewer prison assaults, shortened wait times for treatment programs by nearly two months, reduced the number of prison transfers and lightened the workload of corrections staff.

Corrections officials marvel that nobody thought of it sooner.

“It’s pretty amazing, and what we’ve seen so far is the outcomes are a lot better,” said Major William Nicklow of the state prison in Camp Hill, who oversaw the project as the prison system’s director of population management.

On Tuesday, the Lehigh University team that developed the software accepted the Wagner Prize, the top international prize in the field of operations research practice.

Their work has dramatically simplified the job of assigning inmates to prisons.

Previously, corrections staff handled prisoner assignments one at a time, a laborious and inefficient process that meant inmates farther down the list were at a disadvantage when it came to placement in high-demand treatment programs.

The software, in contrast, can assign hundreds of inmates simultaneously, taking into account dozens of factors including age and other inmate demographics, criminal history, mental illness, and educational and vocational interests to come up with the most appropriate placement for each inmate. It also identifies gang members as well as inmates most likely to be violent and separates them, reducing the threat at individual prisons.

The software can finish in minutes what it took a staff of seven an entire week to do.

“This very complex problem is mathematically modeled, put in the system and the system is advising where the inmate has to be assigned,” said Tamas Terlaky, one of the program’s developers and a professor in Lehigh’s industrial and systems engineering department. “The benefits are quite obvious.”

Other corrections departments have taken note. At least three other states as well as the federal prison system have made inquiries about the software, Terlaky said.

Americans could see a lot more drones flying around their communities as the result of a Trump administration test program to increase government and commercial use of the unmanned aircraft.

President Donald Trump gave the go-ahead Wednesday, signing a directive intended to increase the number and complexity of drone flights.

The presidential memo would allow exemptions from current safety rules so communities could move ahead with testing of drone operations.

States, communities and tribes selected to participate would devise their own trial programs in partnership with government and industry drone users. The administration anticipates approving at least five applications, but there is no limit on the number of communities that can join.

The Federal Aviation Administration would review each program. The agency would grant waivers, if necessary, to rules that now restrict drone operations. Examples include prohibitions on flights over people, nighttime flights and flights beyond the line of sight of the drone operator.

 

Among the things that could be tested are package deliveries; the reliability and security of data links between pilot and aircraft; and technology to prevent collisions between drones and other aircraft and to detect and counter drones flying in restricted areas.

 

Drone-makers and businesses that want to fly drones have pushed for looser restrictions. Trump discussed the issue with industry leaders at a White House meeting in June.

In the past two years, the FAA has registered over 1 million drones. The majority of them belong to hobbyists. There are now more registered drones than registered manned aircraft in the U.S.

Safety restrictions on drone flights have limited drone use, and U.S. technology companies seeking to test and deploy commercial drones have often done so overseas. For example, Google’s Project Wing is testing drones in Australia, and Amazon is testing drone deliveries in the United Kingdom.

“In order to maintain American leadership in this emerging industry here at home, our country needs a regulatory framework that encourages innovation while ensuring airspace safety,” Michael Kratsios of the White House Office of Science and Technology Policy told reporters in a conference call.

The trial program will collect data on drone operations that will aid the government’s effort to develop a separate air traffic control system for low-flying unmanned aircraft, he said.

The test zones are expected to start going into place in about a year. The program would continue for three years after that.

Safety concerns over drones have risen recently after the collision of a civilian drone and an Army helicopter over Staten Island, New York, and the first verified collision in North America between a drone and a commercial aircraft, in Quebec City, Canada.

The test program doesn’t address complaints by local governments that low-flying drones present safety, privacy and nuisance risks. The FAA says it has the sole authority to regulate the national airspace, but some communities have passed their own restrictions.

Doug Johnson, vice president of technology policy at the Consumer Technology Association, said the test program recognizes that “the federal government cannot manage policymaking and enforcement by itself” and must work with local governments.

“Public-private partnerships like those that would be created by the program are critical to realizing the economic benefits of drones,” he said.

The association, whose members include drone-makers, has estimated 3.4 million drones valued will be sold in the U.S. this year, 40 percent more than last year. Revenue from those sales is estimated at about $1.1 billion.

Apple Inc recently allowed its suppliers to reduce the accuracy of the iPhone X’s facial recognition system to speed up production of the smartphone, Bloomberg News reported on Wednesday, citing people familiar with the situation.

The Face ID system – among the $999 iPhone X’s most talked about features – uses a mathematical model of users’ faces to allow them to sign on to their phones or pay for goods with a steady glance at their phones.

Apple could not immediately be reached for comment outside regular business hours.

Apple has been facing a slew of issues with its latest set of phones that it launched on Sept. 12, with the iPhone 8 and 8 Plus facing muted demand, and news and analyst reports suggesting reduced shipment plans for the iPhone X.

The iPhone X is set to be released on Nov. 3.

Twitter Inc said on Tuesday it would add labels to election-related advertisements and say who is behind each of them, after a threat of regulation from the United States over the lack of disclosure for political spending on social media.

Twitter said in a blog post the company would launch a website so that people could see the identities of the buyers, targeting demographics and total ad spending by election advertisers, as well as information about all ads currently running on Twitter, election-related or otherwise.

Silicon Valley social media firms and the political ads that run on their websites have generally been free of the disclaimers and other regulatory demands that U.S. authorities impose on television, radio and satellite services.

Calls for that to change have grown, however, after Twitter, Facebook Inc and Alphabet Inc’s Google said in recent weeks that Russian operatives used fake names on their platforms to spread divisive messages in the run-up to the 2016 U.S. presidential election.

Russia has denied interfering in the election.

Twitter plans to make changes first in the United States and then roll them out globally.

Changes would appear within Twitter feeds, where election ads would have a label like “promoted by political account,” the company said.

“To make it clear when you are seeing or engaging with an electioneering ad, we will now require that electioneering advertisers identify their campaigns as such,” Bruce Falck, Twitter’s general manager of revenue product, said in the blog post.

Twitter also said it would limit the targeting options for election ads, although it did not say how, and introduce stronger penalties for election advertisers who violate policies.

Democratic U.S. Senator Mark Warner said from his Twitter account that the moves by the company were a “good first step” but he added that Congress should make the disclosures mandatory by approving legislation he is co-sponsoring.

Policing difficult

Separately, Twitter has long been criticized by users and lawmakers as lax in policing fake or abusive accounts. Unlike Facebook, Twitter allows anonymous accounts and automated accounts, or bots, making the service more difficult to police.

Twitter said last month it had suspended about 200 Russia-linked accounts as it investigated online efforts to influence last year’s U.S. election.

The general counsels for Facebook, Google and Twitter are scheduled to testify next week before public hearings of the Senate and House intelligence committees.

Facebook Inc said on Monday it was testing the idea of dividing its News F eed in two, separating commercial posts from personal news in a move that could lead some businesses to increase advertising.

The Facebook News Feed, the centerpiece of the world’s largest social network service, is a streaming series of posts such as photos from friends, updates from family members, advertisements and material from celebrities or other pages that a user has liked.

 

The test, which is occurring in six smaller countries, now  offers two user feeds, according to a statement from the company: one feed focused on friends and family and a second dedicated to the pages that the customer has liked.

The change could force those who run pages, everyone from news outlets to musicians to sports teams, to pay to run advertisements if they want to be seen in the feed that is for friends and family.

The test is taking place in Bolivia, Cambodia, Guatemala, Serbia, Slovakia and Sri Lanka, and it will likely go on for months, Adam Mosseri, the Facebook executive in charge of the News Feed, said in a blog post.

Mosseri said the company has no plans for a global test of the two separate feeds for its 2 billion users.

Facebook also does not currently plan to force commercial pages “to pay for all their distribution,” he said.

Facebook, based in Menlo Park, California, frequently tests changes big and small as it tries to maximize the time people spend scrolling and browsing the network. Sometimes it makes changes permanent, and other times not.

Depending on how people respond, two news feeds could mean that they see fewer links to news stories. News has proved to be a tricky area for Facebook, as hoaxes and false news stories have sometimes spread easily on the network.

The test has already affected website traffic for smaller media outlets in recent days, Slovakian journalist Filip Struharik wrote over the weekend in a post on Medium.

Publishers might need to buy more Facebook ads to be seen, he wrote: “If you want your Facebook page posts to be seen in old newsfeed, you have to pay.”

Amazon said Monday that it received 238 proposals from cities and regions in the United States, Canada and Mexico hoping to be the home of the company’s second headquarters.

The online retailer kicked off its hunt for a second home base in September, promising to bring 50,000 new jobs and spend more than $5 billion on construction. Proposals were due last week, and Amazon made clear that tax breaks and grants would be a big deciding factor on where it chooses to land.

Amazon.com Inc. said the proposals came from 43 U.S. states as well as Washington, D.C., and Puerto Rico, three Mexican states and six Canadian provinces. In a tweet, the company said it was “excited to review each of them.”

Besides looking for financial incentives, Amazon had stipulated that it was seeking to be near a metropolitan area with more than a million people; be able to attract top technical talent; be within 45 minutes of an international airport; have direct access to mass transit; and be able to expand that headquarters to as much as 8 million square feet in the next decade.

Generous tax breaks and other incentives can erode a city’s tax base. For the winner, it could be worth it, since an Amazon headquarters could draw other tech businesses and their well-educated, highly paid employees.

The seven U.S. states that Amazon said did not apply were: Arkansas, Hawaii, Montana, North Dakota, South Dakota, Vermont and Wyoming.

Ahead of the deadline, some cities turned to stunts to try and stand out: Representatives from Tucson, Arizona, sent a 21-foot tall cactus to Amazon’s Seattle headquarters; New York lit the Empire State Building orange to match Amazon’s smile logo.

The company plans to remain in its sprawling Seattle headquarters, and the second one will be “a full equal” to it, founder and CEO Jeff Bezos said in September. Amazon has said that it will announce a decision sometime next year.

Electric cars are steadily gaining ground in the global auto market, but it’s a slow process. Along with their high price, one of the main reasons for the consumers’ reluctance is the scarcity of infrastructure needed for charging the cars’ batteries. VOA’s George Putic looks at efforts to remove one of the obstacles on the road towards the electric future.
…

The bumper sticker on the back of Scott Wilson’s car reads, “This is what the end of gasoline looks like.”

And what does that car look like? A sleek, sci-fi experimental vehicle? A $100,000 Tesla luxury car? 

Nope. It’s just a Kia Soul EV, the battery-powered version of the Korean automaker’s boxy hatchback.

Once the domain of concept cars and hobbyists, electric vehicles are no longer so exotic. And sales are picking up. A record 150,000 of them sold last year in the United States.

“It used to be I knew everyone I saw that was driving an electric car,” said Wilson, the vice president of the Electric Vehicle Association of Greater Washington, D.C. “Now, I don’t.”

There are about to be a lot more strangers in EVs on the roads, many experts say.

Big carmakers, big plans

Volvo says every car it makes in 2019 and beyond will have an electric motor. General Motors says the company “believes in an all-electric future.” Bloomberg New Energy Finance (BNEF) predicts that in just over two decades, EVs will make up more than half of all vehicles sold.

Other analysts have more modest expectations. But even Exxon Mobil sees EVs topping 10 percent of the market by 2040.

Automakers hit a significant milestone in the past year. In December, General Motors launched the Chevrolet Bolt EV, the first car with a price tag under $40,000 and a range of more than 320 kilometers.

Automakers hit a significant milestone in the past year. In December, General Motors launched the Chevrolet Bolt EV, the first car with a price tag under $40,000 and a range of more than 320 kilometers.

That range is “basically double anything else that’s available at a comparable price,” said Chevrolet spokesman Fred Ligouri. Those figures “do wonders for getting beyond” what’s known as range anxiety, potential buyers’ fear of draining the battery before reaching their destination.

One-third of buyers have never owned an electric vehicle before.

“They went from (an) internal combustion engine vehicle right into pure electric,” an encouraging sign, Ligouri said.

The Bolt’s performance has impressed critics as well. Motor Trend magazine named the Bolt the 2017 Car of the Year.

The Bolt beat industry upstart Tesla to the mid-priced market. A modest 15,000 or so have been sold so far. But nearly a half-million people have ordered the Tesla Model 3, the company’s entrant into the mass market, despite long waits and slow production.

“Those are signals that there’s unmet demand for some of these new technologies,” said the World Resources Institute’s Eliot Metzger.

Electrification is cheaper than ever as the price of lithium ion batteries plummets faster than analysts expected. As costs come down, experts are moving up the date when electric vehicles can compete with internal combustion engines on price. BNEF puts that date in the second half of the next decade.

“We’re much further along than most researchers (and) industry insiders would have projected just two or three years ago,” said Nic Lutsey at the International Council on Clean Transportation.

China syndrome

Another reason the industry is moving fast: China.

Officials in the world’s biggest auto market will require carmakers to meet an electric vehicle quota starting in 2019.

Beijing aims to increase EVs’ share of the market from 1 to 2 percent today to around 4 percent in 2020.

“That’s a very large scale up within just several years,” Lutsey noted, but automakers say they can do it.

The push for electric vehicles is part of the government’s plan to clean up the toxic air in China’s major cities. Chinese officials are considering a ban on gas- and diesel-powered cars.

But it’s not just China. Pollution concerns in France, the United Kingdom, and India have officials there considering bans, too.

In the United States, the Trump administration aims to relax vehicle emissions standards, though state policies will likely complicate those efforts.

Without a push from government, experts say electric vehicles will have a hard time making major gains as long as gas prices are relatively low.

But as electric vehicle driver Wilson points out, that can change at any time.

“After the next crisis, when gas is $5 a gallon, then there will be waiting lists for cars like this,” he said.
…

Electric cars have been a futuristic promise for decades. And electric vehicles finally appear poised to enter the mainstream. Major carmakers, from Volvo to General Motors, are proclaiming the future is electric. VOA’s Steve Baragona has a look at how soon that future may arrive.

The FBI hasn’t been able to retrieve data from more than half of the mobile devices it tried to access in less than a year, FBI Director Christopher Wray said Sunday, turning up the heat on a debate between technology companies and law enforcement officials trying to recover encrypted communications.

 

In the first 11 months of the fiscal year, federal agents were unable to access the content of more than 6,900 mobile devices, Wray said in a speech at the International Association of Chiefs of Police conference in Philadelphia.

 

“To put it mildly, this is a huge, huge problem,” Wray said. “It impacts investigations across the board – narcotics, human trafficking, counterterrorism, counterintelligence, gangs, organized crime, child exploitation.”

 

The FBI and other law enforcement officials have long complained about being unable to unlock and recover evidence from cellphones and other devices seized from suspects even if they have a warrant, while technology companies have insisted they must protect customers’ digital privacy.

The long-simmering debate was on display in 2016, when the Justice Department tried to force Apple to unlock an encrypted cellphone used by a gunman in a terrorist attack in San Bernardino, California. The department eventually relented after the FBI said it paid an unidentified vendor who provided a tool to unlock the phone and no longer needed Apple’s assistance, avoiding a court showdown.

The Justice Department under President Donald Trump has suggested it will be aggressive in seeking access to encrypted information from technology companies. But in a recent speech, Deputy Attorney General Rod Rosenstein stopped short of saying exactly what action it might take.

 

“I get it, there’s a balance that needs to be struck between encryption and the importance of giving us the tools we need to keep the public safe,” Wray said.

 

In a wide-ranging speech to hundreds of police leaders from across the globe, Wray also touted the FBI’s partnerships with local and federal law enforcement agencies to combat terrorism and violent crime.

 

“The threats that we face keep accumulating, they are complex, they are varied,” Wray said, describing threats from foreign terror organizations and homegrown extremists.

Wray also decried a potential “blind spot” for intelligence gathering if Congress doesn’t reauthorize an intelligence surveillance law set to expire at the end of the year. The Foreign Intelligence Surveillance Act allows the government to collect information about militants, people suspected of cyber crimes or proliferation of weapons of mass destruction, and other foreign targets outside the United States. Intelligence and law enforcement officials say the act is vital to national security.

 

A section of the act permits the government, under the oversight of the Foreign Intelligence Surveillance Court, to target non-Americans outside the United States.

 

“If it doesn’t get renewed or reauthorized, essentially in the form that it already is, we’re about to get another blind spot,” Wray said.

The Department of Homeland Security and Federal Bureau of Investigation warned in a report distributed by email late on Friday that the nuclear, energy, aviation, water and critical manufacturing industries have been targeted along with government entities in attacks dating back to at least May.

The agencies warned that hackers had succeeded in compromising some targeted networks, but did not identify specific victims or describe any cases of sabotage.

The objective of the attackers is to compromise organizational networks with malicious emails and tainted websites to obtain credentials for accessing computer networks of their targets, the report said.

U.S. authorities have been monitoring the activity for months, which they initially detailed in a confidential June report first reported by Reuters. That document, which was privately distributed to firms at risk of attacks, described a narrower set of activity focusing on the nuclear, energy and critical manufacturing sectors.

Department of Homeland Security spokesman Scott McConnell declined to elaborate on the information in the report or say what prompted the government to go public with the information at this time.

“The technical alert provides recommendations to prevent and mitigate malicious cyber activity targeting multiple sectors and reiterated our commitment to remain vigilant for new threats,” he said.

The FBI declined to comment on the report, which security researchers said described an escalation in targeting of infrastructure in Europe and the United States that had been described in recent reports from private firms, including Symantec Corp.

“This is very aggressive activity,” said Robert Lee, an expert in securing industrial networks.

Lee, chief executive of cyber-security firm Dragos, said the report appears to describe hackers working in the interests of the Russian government, though he declined to elaborate. Dragos is also monitoring other groups targeting infrastructure that appear to be aligned with China, Iran, North Korea, he said.

The hacking described in the government report is unlikely to result in dramatic attacks in the near term, Lee said, but he added that it is still troubling: “We don’t want our adversaries learning enough to be able to do things that are disruptive later.”

The report said that hackers have succeeded in infiltrating some targets, including at least one energy generator, and conducting reconnaissance on their networks. It was accompanied by six technical documents describing malware used in the attacks.

Homeland Security “has confidence that this campaign is still ongoing and threat actors are actively pursuing their objectives over a long-term campaign,” the report said.

The report said the attacker was the same as one described by Symantec in a September report that warned advanced hackers had penetrated the systems controlling operations of some U.S.

and European energy companies.

Symantec researcher Vikram Thakur said in an email that much of the contents of Friday’s report were previously known within the security community.

Cyber-security firm CrowdStrike said the technical indicators described in the report suggested the attacks were the work of a hacking group it calls Berserk Bear, which is affiliated with the Russian Federation and has targeted the energy, financial and transportation industries.

“We have not observed any destructive action by this actor,” CrowdStrike Vice President Adam Meyers said in an email.

Parents of small children have long been hearing about the perils of “screen time.” And with more screens, and new technologies such as Amazon’s Echo speaker, the message is getting louder.

And while plenty of parents are feeling guilty about it, some experts say it might be time to relax a little.

Go ahead and hand your kid a gadget now and then to cook dinner or get some work done. Not all kids can entertain themselves quietly, especially when they are young. Try that, and see how long it takes your toddler to start fishing a banana peel out of the overflowing trash can.

“I know I should limit my kid’s screen time a lot, but there is reality,” said Dorothy Jean Chang, who works for a tech company in New York and has a 2-year-old son. When she needs to work or finds her son awake too early, “it’s the best, easiest way to keep him occupied and quiet.”

Screen time, she says, “definitely happens more often than I like to admit.”

She’s not alone. Common Sense Media, a nonprofit group focused on kids’ use of media and technology, said in a report Thursday that kids ages 8 and younger average about 2 hours and 19 minutes with screens every day at home. That’s about the same as in 2011, though it’s up from an hour and a half in 2013, the last time the survey was conducted, when smartphones were not yet ubiquitous but TV watching was on the decline.

While the overall numbers have held steady in recent years, kids are shifting to mobile devices and other new technologies, just as their parents are. The survey found that kids spend an average of 48 minutes a day on mobile devices, up from 15 minutes in 2013. Kids are also getting exposed to voice-activated assistants, virtual reality and internet-connected toys, for which few guidelines exist because they are so new.

​Mixed message

Some parents and experts worry that screens are taking time away from exercise and learning. But studies are inconclusive. 

The economist Emily Oster said studies have found that kids who watch a lot of TV tend to be poorer, belong to minority groups and have parents with less education, all factors that contribute to higher levels of obesity and lower test scores. For that reason, it’s “difficult to draw strong conclusions about the effects of television from this research,” Oster wrote in 2015.

In fact, the Common Sense survey found that kids whose parents have higher incomes and education spend “substantially less time” with screens than other children. The gap was larger in 2017 than in previous years.

Rules relaxed

For more than a quarter century, the American Academy of Pediatrics held that kids under 2 should not be exposed to screens at all, and older kids should have strict limits. The rules have relaxed, such that video calls with grandma are OK, though “entertainment” television still isn’t. Even so, guidelines still feel out of touch for many parents who use screens of various sizes to preserve their sanity and get things done.

Jen Bjorem, a pediatric speech pathologist in Leawood, Kansas, said that while it’s “quite unrealistic” for many families to totally do away with screen time, balance is key.

“Screen time can be a relief for many parents during times of high stress or just needing a break,” she said.

Moderation

Bjorem recommends using “visual schedules” that toddlers can understand to set limits. Instead of words, these schedules have images — dinner, bed time, reading or TV time, for example. 

Another idea for toddlers? “Sensory bins,” or plastic tubs filled with beads, dry pasta and other stuff kids can play around with and, ideally, be just as absorbed as in mobile app or an episode of “Elmo.”

Of course, some kids will play with these carefully crafted, Pinterest-worthy bins for only a few minutes. Then they might start throwing beans and pasta all over your living room. So you clean up, put away the bins and turn on the TV.

In an interview, Oster said that while screen time “is probably not as good for your kid as high-quality engagement” with parents, such engagement is probably not something we can give our kids all the time anyway.

“Sometimes you just need them to watch a little bit of TV because you have to do something, or you need (it) to be a better parent,” Oster said.

The Group of Seven industrialized nations threw their support behind a new technology industry alliance aimed at detecting and blunting online propaganda, saying Friday it had a “major role” to play in combating extremism on the internet.

G-7 interior ministers meeting in Italy invited representatives from Google, Microsoft, Facebook and Twitter to a session Friday dedicated to the fight against terrorism. In a final communique, the ministers pressed the industry as a whole to do more.

“Internet companies will continue to take a proactive role and ensure decisive action in making their platforms more hostile to terrorism, and will support actions aimed at empowering civil society partners in the development of alternative narratives online,” the statement said.

Social media companies have long seen themselves as neutral platforms for other people to share information, and have traditionally been cautious about taking down objectionable material. But as social media platforms have increasingly been used to recruit jihadis, radicalize young people, share fake news and incite extremism, they have come under pressure from governments to take action.

Facebook, Google, Twitter and YouTube in June created the Global Internet Forum to Combat Terrorism, which got an early boost when British Prime Minister Theresa May used a speech to the U.N. General Assembly to applaud the initiative and demand internet companies develop technology to more quickly identify and remove terrorist content.

The alliance says it is committed to developing new content detection technology, to helping smaller companies combat extremism and to promoting “counter-speech,” content meant to blunt the impact of extremist material.

The G-7 endorsed the aims and pledged to work collaboratively across the industry to counter the “misuse of technology” by terrorist organizations.

Italian Interior Minister Marco Minniti said “a great alliance” had been formed between world governments and major internet providers. While stressing the internet has been an important tool for promoting freedom, “at the same time we all together have agreed that al-Qaida and Islamic State are enemies of our freedoms.”

Several ministers said that while the industry had made progress to quickly remove extremist content, more needed to be done, and faster.

“Our enemies are moving at the speed of a tweet, so we have to counter them just as quickly,” said acting U.S. Homeland Security Secretary Elaine Duke.
