Facebook to roll out fake news tools in Germany

Facebook logos

Facebook is introducing new tools in Germany to help combat the spread of fabricated news stories.

The world's largest social network said it would enable German users to flag potentially false stories.

The stories will then be passed to third-party fact-checkers and if found to be unreliable, will be marked in users' news feeds as "disputed".

It is the first major rollout of the fake news features announced by Facebook in December.

"Last month we announced measures to tackle the challenge of fake news on Facebook," the company said on Sunday in a German-language statement.

"We will put these updates in place in Germany in the coming weeks."

Facebook has been widely criticised after some users complained that fake news had influenced the US presidential election.

German government officials have expressed concern that misinformation on the internet could influence the country's parliamentary election this year.

Last week, the social news site Buzzfeed found Facebook pages were publishing false stories about German Chancellor Angela Merkel, who is seeking re-election.

German Justice Minister Heiko Maas has also repeatedly warned about fake news on Facebook, and called on the firm to respect the country's defamation laws, which are stricter than in the US.

In the UK, MPs are set to question executives from Facebook, Google and Twitter about fake news amid fears it is undermining democracy, according to a report in the Sunday Telegraph.

Under the new measures, users in Germany will be able to select "It's a fake news story" as an option when reporting another user's post.

They can then mark the post as fake news, let the other user know they think it is fake, or block that user.

Facebook will send potentially fake stories to Correctiv, a German non-profit body of investigative journalists, to check the facts.

If they find a story to be false, it will be marked on Facebook as "disputed" and will appear lower in users' news feeds.

Facebook is already working with other fact-checkers in the US to verify news on its platform.

The fact-checkers must sign up to a code of principles to take part. There are currently 43 signatories, including news organisations in several different countries.

Facebook Germany also said it was looking into penalising websites, which tried to mimic major publishers or misled readers into thinking they were a well-known news source.

Last week, the company announced new training and tools that would be made available for journalists on its platform.

On Thursday, BBC News said it would expand its Reality Check series to target false stories or facts being shared widely on social media.

Marissa Mayer not on new Yahoo holding group board

Marissa Mayer

Yahoo says its chief executive Marissa Mayer will not be on the board of a company that emerges from the $4.83bn (£4bn) takeover deal by Verizon.

Yahoo is in the process of selling its email, websites, mobile apps and advertising tools to Verizon.

What is left after that sale will be owned by a holding company to be named Altaba.

Its main assets will be a 15% stake in Chinese e-commerce firm Alibaba and a 35.5% stake in Yahoo Japan.

Five other current members of the Yahoo board also won't be on the board of the new firm.

Ms Mayer is expected to remain with Yahoo's core business.

Verizon's deal for Yahoo's core internet assets came under renewed scrutiny last month after the Yahoo disclosed one of the largest known data breaches in history.

Verizon is examining the impact of the data breach and there is speculation that the deal may not go through.

Google Waymo self-driving minivan tests to start

John Krafcik and a Waymo vehicle

Google's Waymo will launch the first public road tests of its self-driving minivans later this month.

The trials will take place in California and Arizona, according to Waymo chief executive John Krafcik.

Modified Chrysler Pacificas with Waymo-designed sensors were on display at the North American International Auto Show in Detroit, where Mr Krafcik spoke.

One tech analyst said the industry would keenly watch Waymo's performance in the coming months.

Waymo plans to develop self-driving technology and provide it to established carmakers. The company was formally launched by Google in December.

Mr Krafcik said the company had managed to reduce the cost of producing its Lidar laser-based sensor, though did not give details about how, according to Associated Press.

He added that he expected Waymo to have completed three million miles of test-driving by May.

"The Waymo self-driving program is the first true end-to-end integrated solution that we see in the market today," said Arunprasad Nandakumar, a tech analyst with Frost & Sullivan.

"In the coming months, the Waymo minivan will give clearer indications on whether the industry will be able to meet the steep targets that have been publicly announced by various players."

PewDiePie quit plan prompts YouTube reply

PewDiePie

YouTube has denied making changes to its algorithms, after its most popular star said he would delete his channel.

Video gamer Felix Kjellberg, known as PewDiePie, suggested changes to YouTube's algorithms had affected the discoverability of creators' content.

On Tuesday, a Forbes report named the Swedish gamer who now lives in the UK as the highest-earning YouTuber.

YouTube told the BBC it had not made any changes to its "suggested videos" algorithms.

However, other video-makers have reported the same problem, with new videos being viewed fewer times than old content.
Algorithms

The "suggested videos" feed appears when a video is being watched, and recommends more content to watch.

Mr Kjellberg said the feed usually accounted for more than 30% of his video traffic, but in recent weeks it had suddenly fallen to under 1%, signalling an undisclosed algorithm change.

Other criticisms aimed at YouTube included suggestions that:

    channels he had previously subscribed to had been removed from his subscriptions list
    the homepage - which in 2006 used to show videos from channels the user had chosen to subscribe to - was now filled with "recommended" videos viewers were not interested in
    the suggested videos feed favoured click bait and pornography

Film-makers have argued that YouTube has made it more difficult for fans to keep track of their latest uploads, and for new viewers to discover their content, since the platform was acquired by Google.

In a video uploaded on Friday, video gamer Mr Kjellberg said he would delete his channel when it reached 50 million subscribers as a result of his frustration with the platform.

His channel, currently the most-followed on the video-sharing site, is about 200,000 subscribers short of that target.

However, when asked by the BBC, YouTube denied that it had made any changes to its algorithms in recent months.

It added that it had found no evidence that people were being unsubscribed from channels they followed.

A spokeswoman said: "Some creators have expressed concerns around a drop in their subscriber numbers.

"We've done an extensive review and found there have been no decreases in creators' subscriber numbers beyond what normally happens when viewers either unsubscribe from a creator's channel or when YouTube removes spammed subscribers."

Mr Kjellberg is currently producing new episodes of his YouTube-financed series Scare PewDiePie, and on Tuesday topped Forbes' list of highest-paid YouTube stars for the second year in a row.

His PewDiePie gaming channel is likely to reach 50 million subscribers in a matter of days.

Mr Kjellberg suggested at that stage he would "start fresh" with a new channel, although some have taken his claim as light-hearted.

Apple Music attracts 20 million subscribers in 18 months

Eddy CueZane Lowe

Apple Music has said it will continue to tie artists to exclusive deals, as its number of paid subscribers passes 20 million for the first time.

There has been criticism that putting albums behind a streaming paywall harms fans and, ultimately, artists.

"I don't think exclusives or promotions are anything new," Apple Music boss Eddy Cue said.

"They were done in the record business, they were done on iTunes, now they're being done on streaming."

He continued: "The exclusives are relatively short term - it's not something that stays on any one platform. But being able to do unique things with artists is a good thing and I think that'll continue."

Cue said Apple had hosted 70 exclusives over the last year, six of which topped the US Billboard charts, including Drake's Views.

Apple also streamed Chance The Rapper's Coloring Book, which made history on Tuesday by becoming the first album to be nominated for the Grammys without being available in shops or download stores.

However, Universal Music Group chief executive Lucian Grainge recently called for an end to exclusives.

And Kanye West has said streaming companies are engaged in a testosterone-fuelled battle that was ruining the music industry - despite releasing his own album as an exclusive on Jay Z's Tidal service.

Cue told the BBC that exclusives were "not the answer to everything" but they "served their purpose".

One purpose is undoubtedly to attract new customers - and Apple has gained three million new subscribers in the last three months.

The tech company said 60% of its users had not downloaded a song from the iTunes store over the last 12 months, suggesting they were a "whole new audience".

Launched in June 2015, Apple Music has swiftly become the second biggest player in the market - behind Spotify, which now boasts 40 million subscribers.

Their popularity has helped reinvigorate the music industry, which recently saw its first big gain in revenue for 20 years.

The increase was largely due to a 45% increase in streaming revenue, with sites like Apple, Deezer, Tidal and Spotify charging £10 per month for instant access to millions of songs.

Cue and Apple Music DJ Zane Lowe spoke to the BBC as the company revealed its most popular music and apps of 2016.

Zane, what's your view of music in the last 12 months?

Zane Lowe: It's been a mad year, hasn't it? When I think back over the last 12 months, I've turned to music so many times. It's been the consistent bringer of joy in an otherwise fairly emotional year.

A lot of huge superstars have really shown themselves to be just that this year, [with] people like Drake releasing multiple records. And I think Skepta is the number one superstar coming out of the UK in 2016.

Drake is doing huge numbers on streaming - but that means he dominates the charts at the expense of new music. Does that concern you?

ZL: I don't run the charts and I don't have any influence over the charts. What we do is we focus on bringing new music to its audience, and that's always been the equation that matters to us. Where the charts fit in to that, I don't give any huge amount of thought, to be honest with you.

Is it possible to create a star entirely within the Apple Music ecosystem, without TV or magazines or radio play?

Eddy Cue: I think we've shown with somebody like Chance The Rapper that we can bring him into the charts.

ZL: Take Christine and the Queens - she was only recognised in France when we started playing her and all of a sudden she is regarded as one of the breakout artists of the last 12 to 18 months.

It won't come as a surprise when I tell you that I think Beats 1 and Apple Music have played a really valuable role in bringing an artist like Christine to a global audience,.

Most streaming services charge £10 a month - but recently Amazon Unlimited and Electric Jukebox have started experimenting with lower prices. How closely are you monitoring their subscriber numbers?

EC: We watch what all of our competitors are doing. There are a lot of promotions and different ways for people to do things around pricing. But we're looking at ways to help artists get discovered, to make it easier for you to listen to music. All those kinds of things is the focus we have.

You've done well from exclusives this year, but a lot of fans get aggrieved when their favourite artist streams music exclusively on a service they don't subscribe to. Will you continue to pursue those deals?

EC: I don't think exclusives or promotions are anything new. They were done in the record business, they were done in the cassette business, they were done on iTunes and now they're being done on streaming.
The exclusives are relatively short term - it's not something that stays on any one platform. But being able to do unique things with artists is a good thing and I think that'll continue.

If you look at Kanye's latest album The Life Of Pablo, it was pirated hundreds of thousands of times when it was an exclusive on Tidal. Isn't that damaging to the industry?

EC: Again, if done correctly, I think they can serve a purpose. They're not the answer to everything. But when we've done things with Drake, for example, or Frank Ocean, they've worked really well for them and for us.

How important is it to invest in content now that iPhone sales are slowing down?

EC: That's a loaded question! Look, I think we are going to continue to invest in music in a huge way, whether it's new pieces of software, Beats headphones or the audio that we do.

We've just released the greatest-sounding iPhone we've ever done with stereo speakers, so we're committed to audio and the music business in a huge way - along with continuing to invest in all of our hardware business which is doing quite well.

Would you consider upgrading Apple Music to high-fidelity or "lossless" audio?

EC: There's a lot of talk about that - but what we've focused on is making sure we get the best masters.

One of the things we realised early on when we were doing iTunes was that the quality of the songs we were getting sometimes weren't the best - because they weren't coming directly from the master tapes. They had already been pre-processed and all that.

Virgin Media unveils 4K box and large tablet

Virgin V6 box

Virgin Media has launched its first 4K TV set-top box, offering four times the resolution of high definition broadcasts.

The firm also unveiled a large tablet and an online store from which its UK customers will be able to purchase HD, but not 4K, content - it had only sold rentals before.

Its pay-TV rivals BT and Sky already offer 4K services of their own.

One expert suggested Virgin's initial line-up of content might disappoint.

"Virgin Media will hope that this well long overdue move will help boost its declining TV base," said Paolo Pescatore from the technology consultancy CCS Insight.

"For the first time in a while its total TV subscribers grew in the last quarter, reversing a worrying trend seen over the last couple of years.

"But despite claims that the box is future-proof, it lacks premium 4K content such as live sport and on-demand movies, unlike rivals, which is something that it needs to address.

"However, its hands are tied due to the high fees BT Sport and Sky will most likely command [for their content]."

Virgin's chief digital entertainment officer has played down the issue.

"The box is 4K capable and therefore future-proof," David Bouchier told the BBC.

"Do we see a significant demand sitting here in 2016 for a large amount of 4K programming by the majority of our subscriber base? No we don't.

"We would quite happily put the 4K football matches on if we felt that this was something that our customers were saying.

"I'm not saying that it's like 3D [which failed to catch on], but we need to wait and see exactly what people think.

"It's not something that is a must have.

"What is a must-have is six-times recording [where the new box records six shows simultaneously], that's what they really want."

For now, the V6 box also lacks HDR (high-dynamic-range) playback, a technology that allows images to reveal more detail and display a wider range of colours.

But Mr Bouchier said he hoped to add the facility some time next year when the chip-maker Broadcom released new firmware for the processor inside the device.

Virgin is charging a one-off fee of £99.95 for the box, but it does not require subscribers to take out a new contract or pay more per month than otherwise.

Portable screen
TellyTablet 
Virgin has also introduced the TellyTablet, which runs the old Marshmallow version of Android, and is an optional extra purchase.

It features a 14in (35.6cm) touchscreen, making it larger than both Apple and Amazon's biggest tablets, but smaller than Samsung's Galaxy View.

Fitted with four speakers, the new device is being pitched as a way to watch TV around the home.

It contrasts with Sky's approach, which involves offering a small wi-fi equipped box that extends its service to multiple TVs.

The TellyTablet is limited to 1080p HD playback, which has helped keep down its cost.

"It's not a service enhancement that we would have guessed before we heard it because tablet sales have already started slowing," commented Ed Barton from the consultancy Ovum.

"The two things that stood out are that it's big and it's relatively cheap.

"But the question is: how much of an overlap is there between Virgin subscribers and those that want a big £300 tablet? I'm not sure it's going to be huge."

 
Movies in the post
Kids app

Virgin is also adding new services including a Kids app, which brings together cartoons, TV shows, interactive games and picture books in one place.

It is targeted at children aged three-to-six years old and guarantees no advertisements or in-app fees. However, it is limited to the firm's premium subscription options.

The company's new online store will let people buy digital copies of movies shortly after their cinema run, and then be sent a physical disc-based copy when it becomes available.

Mr Bouchier acknowledged that Virgin was adopting a practice pioneered by Sky in April 2015.

"Sky was very successful and within a very short space of time had a bigger market share than iTunes," he said.

"One of the major reasons for that was that it had the DVD-to-the-home as an integral part of the proposition.

"So, we will be one of only two places where you will get the electronic version in your digital locker... and also a DVD in the post."

But Mr Barton said Virgin might find it harder to succeed.
"

What Sky has is its own TV channels on which it has run adverts very aggressively promoting the release of movies in its Store," he explained.

"It worked very well for tent-pole releases, such as the recent Star Wars movie.

"So one wonders what Virgin's marketing and communications will be, as it won't work just by setting the store up."

Snapchat unveils strange vending machine for its sunglasses

snap spectacles bot

Snapchat is now selling smart sunglasses from a smiling yellow vending machine that it just deposited near a beach in California.

Yes, you read that sentence correctly.

Snapchat unveiled a new line of funky sunglasses with a built-in wireless video camera in September, marking its first big move from apps to hardware. At the same time, the company renamed itself Snap Inc.

Now those glasses, called Spectacles, are finally going on sale for $129.99, but there's a catch.

The company is only selling the glasses from unusual anthropomorphic vending machines called Snapbots, which look more than a little bit like Minions.

The first (and so far only) vending machine "landed" near Snapchat's headquarters in Venice Beach on Thursday. Snapchat has created a map for customers to keep track as additional vending machines are added or relocated.

Related: Google Capital is now an investor in Snapchat

It's unclear how many vending machines Snapchat intends to install. Reps for Snapchat did not immediately respond to a request for comment

Some Snapchat fans quickly made the trek to the first vending machine on Thursday morning. By the afternoon, there were Spectacles listed for resale on eBay for as much as $950.
Snapchat's sunglasses have drawn comparisons to Google Glass, another smartglasses product that ultimately flopped after a period of public beta testing. If nothing else, it's clear that Snapchat is following a very different playbook.

Blippar wants your face in its app

Blippar

Ever seen someone across a crowded room and struggled to remember who they are? Well now there's an app which would allow you to fit the face to a name.

Blippar, the augmented reality business, is adding facial recognition to its app. Some will find that cool, others will see it as a creepy invasion of privacy.

At the moment the Blippar app gives you information about all kinds of objects when you point your smartphone's camera at them - it will identify famous paintings for example, or provide advertising content when you point it at a product.

Now the app will also recognise people - in real life or in photos and videos.

Blippar's co-founder Omar Tayeb gave me a demonstration, pointing the app at magazine pictures of Michael Fassbender and Hillary Clinton, then at a TV interview with Boris Johnson. In each case, the app recognised the faces and provided information about them - their social media profiles and Wikipedia entries.

He explained that Blippar had made more than 70,000 "public figures" recognisable by the app. I was rather surprised when he pointed the phone at me to find I was among them.

Users will soon be able to upload their own faces.

Here is where some people will feel uneasy. Do you like the idea that a stranger could come up to you in the street and scan your face to find out more about you? Google decided to ban facial recognition apps from its ill-fated Google Glass device amid concerns about privacy.

In Russia an app that combined a neural network with facial recognition software scanned social media profiles to link names and photos. This was then used to identify women who had appeared in pornographic movies.

But Mr Tayeb says privacy is "baked into" the Blippar app.

"It's a totally opt-in service, the user has full control over what's shown and they're able to deactivate it at any time," he explains.

Anyone who does not want their face stored on Blippar's servers, including those 70,000 public figures, can ask to have it removed.

But what happens if a mischievous friend decides to take a photo of you and put it into the database?

Mr Tayeb says the process of creating a face profile involves you taking moving pictures of your own face and claims the system is sophisticated enough to recognise if someone is trying to register someone else.

Blippar believes it is creating a new form of communication involving the most expressive single feature we possess - our faces.

"It's a social tool, something people can have fun with," says Mr Tayeb.

I'm not entirely clear why people will find facial recognition compelling - though as I get older and more forgetful I can imagine that contact lenses that could tell me exactly who I was talking to would be useful.

Blippar's technology is certainly impressive. But in an era where our every move is watched over by CCTV cameras, the idea of smartphone lenses examining our faces wherever we go may not get the warmest of welcomes.

Online shoppers 'face disruption' from EU payment plans

Woman shopping online

EU proposals to make consumers go through extra security checks for many online payments have come under fire from Visa and other payment companies.

Consumers would need to enter passwords or codes for online transactions above €10 (£8.50), under anti-fraud plans from the European Banking Authority.

The regulator said it was trying to balance security with convenience.

But payment company Visa said the plans could be "catastrophic", and banks and retailers have expressed concerns.

Shoppers would face disruption, particularly during busy periods such as Black Friday - the annual discount day that falls this week.

One-click shopping and automatic app payments would also effectively be blocked for payments of more than €10, experts said.
'Catastrophic'

Visa warned of "serious disruption" from blocking such express checkouts, which it said now accounted for half of European e-commerce sales.

The damage would be worst in the UK, because online shoppers there were the most prolific in Europe and e-commerce was important for economic growth, it said in a statement.

"We do not normally take such a strong position on regulation," Kevin Jenkins, managing director of Visa UK and Ireland, told the BBC.

"It's just that in this particular instance we feel so strongly that the risk of rushing into legislation, which could take you back 10 or 15 years, is catastrophic," he said.
Visa's chief risk officer for Europe, Peter Bayley, also said there was no evidence the inconvenience would reduce fraud.

The changes are under consultation, and if approved, will come into force during 2018, several months before the UK is expected to leave the European Union.

Most of the responses to the consultation focused on the €10 security checks, Tim Richards, a payments expert at Consult Hyperion, said.

"All the UK banks and payment institutions are working on this. They do not think this is something they can ignore," he added.
'Unfriendly'

A MasterCard spokesman said it was concerned the "overly prescriptive approach of how fraud should be reduced" would undermine the regulator's overall goal.

In its consultation response, Paypal said "unfriendly" security checks would affect "almost any digital payment, regardless of the actual risk posed".

Mr Richards said under the plans, payments above €10 would require proof of at least two of the following:

    a possession of the consumer, eg a card or phone
    something known by the consumer, eg a password or code
    a biometric feature of the consumer, eg a fingerprint

The European Banking Authority said it had to make a "difficult trade-off" between a high degree of security in retail payments and customer convenience.

"We are currently in the process of assessing whether the trade-offs we made achieve the right balance and which, if any, changes we will need to make before finalising the technical standard and publishing it at the beginning of next year," it said in a statement.

The changes are part of the European Commission's forthcoming Payment Services Directive 2.

Malware is making ATMs 'spit cash'

money coming out of ATM

A Russian cybersecurity firm has issued a warning about a spate of remotely coordinated attacks on cash machines.

Hacks of banks' centralised systems had made groups of machines issue cash simultaneously, a process known as "touchless jackpotting", said Group IB.

The machines had not been physically tampered with, it said, but "money mules" had waited to grab the cash.

Affected countries are said to include Armenia, Estonia, the Netherlands, Poland, Russia, Spain and the UK.

But the company declined to name any specific banks.

Dmitriy Volkov from Group IB told the BBC a successful attack could net its perpetrators up to $400,000 (£320,000) at a time.

"We have seen such attacks in Russia since 2013," he said.

"The threat is critical. Attackers get access to an internal bank's network and critical information systems. That allows them to rob the bank."

Two cash machine manufacturers, Diebold Nixdorf and NCR Corp, told Reuters they were aware of the threat.

"They are taking this to the next level in being able to attack a large number of machines at once," said senior director Nicholas Billett, from Diebold Nixdorf.

"They know they will be caught fairly quickly, so they stage it in such a way that they can get cash from as many ATMs as they can before they get shut down."
'Follow the money'

A recent report by Europol warned of the rise of cash-machine-related malware, although it said "skimming" - using hardware to steal card information at the machine itself - was still more common.

"The new method is being done by somehow gaining access to the banks' central systems and infecting whole communities of ATMs simultaneously, hence multiplying the amount of money that can be stolen in a short time," said Surrey University's cybersecurity expert Prof Alan Woodward.

Because criminals were collecting the cash in person, it made the crime more difficult to trace, he added.

"The classic way of solving online financial crime is to 'follow the money' - but when you can no longer do this, it is very hard to find out who is behind it, even though the evidence suggests it is a very limited number of groups that have started perpetrating this type of crime."

Smart map aims to avoid 5G dead zones

Ordnance Survey

Next-generation smartphones could avoid signal drop-outs thanks to new data-rich maps being produced by Ordnance Survey.

The detailed 3D models feature buildings, proposed constructions, hills, trees and weather cycles, all of which can interfere with 5G signals.

Researchers will be able to test towers in various locations and instantly see how well they might perform.

One analyst said the tool would help networks provide better coverage.

Map of Bournemouth with red and green colouring

Next-generation 5G networks will offer consumers faster connections and increased bandwidth for activities such as video streaming.

But Ordnance Survey says the higher frequency signals have a shorter range than current 3G and 4G signals, and are more susceptible to interference from "even raindrops and leaves".

The planning tool will use Ordnance Survey's mapping data and high-resolution aerial images to produce its 3D models, while weather data will be provided by the Met Office.

"The character of 5G means the location of cell towers is more sensitive - so it will be very important to fully understand the topography of each area," said Ben Wood, analyst at CCS Insight.

"The better the tools networks have to help site cell towers correctly, the more likely we'll get high quality coverage from the get-go."

Ordnance Survey said its maps were so detailed, they even included vegetation cycles to determine how trees might affect 5G coverage during different seasons.

Parts of Bournemouth have already been modelled using the experimental tool, which Ordnance Survey hopes will be rolled out across the UK.

"It will be a useful tool for companies deploying 5G networks," said Mr Wood. "But there is no alternative to spending the money to install a lot of cell sites."

SpaceX aims to launch internet from space

SpaceX spacecraft

 Private rocket firm SpaceX has applied for government permission to launch satellites that will provide global broadband internet access.

In a filing to the US Federal Communications Commission (FFC), it laid out details about its plans for a 4,425-strong satellite network.

It is one of several companies aiming to deploy satellite-based internet services over the next few years.

SpaceX suffered a setback in September when a rocket exploded.

In a statement, the firm said: "Once fully deployed, the SpaceX system will pass over virtually all parts of the Earth's surface and therefore, in principle, have the ability to provide ubiquitous global service."

The satellites would orbit the planet at altitudes ranging from 714 to 823 miles (1,150 to 1,325 km). That is above the International Space Station but below geostationary satellites.

Analysis - Jonathan Amos, Science correspondent

SpaceX has talked about its telecoms ambitions for a while.

Now, under a deadline to file interest with the FFC, the company has given a more technical glimpse of its proposal.

Some 4,425 satellites (plus spares), operating in 83 orbital planes, at altitudes ranging from 689 miles to 823 miles (1,110 km to 1,325 km).

It is understood SpaceX has some prototype satellites it will launch next year, but the actual constellation will not see the light of day until the turn of the decade.

SpaceX is by no means the only group looking to make a pitch in this market. Established satellite communcations big-hitters such as Intelsat (OneWeb), SES (O3B), Telesat and Boeing are at various stages in their own development plans.

It used to be that "constellation" was a dirty word after the initial attempts at building sat phone networks in the 1990s filed for bankruptcy, unable to pay back huge loans. But the wind has changed.

Connectivity drives the global economy and with the coming "internet of things", there is a feeling that these mega-networks in the sky will prove profitable. Not for all, but perhaps for those able to move quick enough and get their constellations launched. And SpaceX's main business is launching satellites.

Elon Musk, the founder of SpaceX, announced last year that the service would be "larger than anything that has been talked about to date" adding that it would take about $10bn (£8bn) to get it off the ground.

The latest documents did not include costs.

It suggested that the first 800 satellites would be used to expand internet access in the US, including Puerto Rico and the US Virgin islands.

Each satellite, about the size of an average car, not including solar panels, would weigh 850 pounds (386kg), the firm said.

SpaceX rocket launches have been on hold since September following an accident that destroyed a $62m Falcon 9 booster and a $200m Israeli communication satellite. The firm hopes to resume flights next month.

Facebook fake news row: Mark Zuckerberg is a politician now

Mark Zuckerberg

I’ve long suspected that Mark Zuckerberg, who often refers to himself as the “leader” of Facebook, has dreams of high office.

This week, a taster of what that might be like has been knocking at his door in the wake of the US election result.

While Donald Trump’s visit to the White House was an apparently sobering experience about the level of responsibility he’d soon inherit, Zuckerberg has had a brutal political awakening of his own.

Facebook’s “fake news” crisis has had the normally stoic 32-year-old visibly irritated, and that’s because for the first time he is being treated like a politician, rather than just a tech CEO.

With that comes distrust and anger, not to mention disloyalty in the Facebook ranks and what for him must be the growing realisation that it’s impossible to please everyone.

Whether Zuckerberg was right to say fake news had little impact is largely irrelevant. By dismissing it apparently without second thought as “crazy”, he attracted a global pitchfork of people demanding that he at the very least acknowledge the potential role his empire had in Donald Trump’s election win.

That interview, carried out by journalist David Kirkpatrick, also contained one other exchange which should give Zuckerberg some serious food for thought -  and may even represent the biggest threat the network and its leader is yet to face.
Checks and balances

Kirkpatrick first laid out the context.

Facebook, he said, was the most influential commercial enterprise ever created, with unparalleled power that is yet to be fully understood.

Zuckerberg himself is a multi-billionaire in charge of a network that has intricate personal data on 1.8 billion people and counting.

“What are the checks and balances that need to exist for this new kind of entity?” asked Kirkpatrick.

“Do you think about that? At the moment it seems like you are the check and balance.”

Zuckerberg’s answer didn’t come close to addressing the question. He said it was about “listening to what people want”, and continuing to give people “the power to share” and to make “the world more open and connected”.

But is he confident the checks and balances are in place to stop Facebook over-stepping the mark?

“I mean… yeah,” he said, peering out into the audience for support.

Even though I was watching via a live stream, I could tell the room took an awkward turn. Kirkpatrick moved on - but the issue won’t.
The accountability gap

The exchange had touched upon a problem that surely deserves more attention.

There’s an urgent accountability gap between what technology companies do and what the public is allowed to know.

This isn’t about giving up trade secrets. You can inspect KFC’s kitchen without knowing the Colonel’s secret recipe.

It’s about being able to examine the reach and influence of technology companies, where supremely powerful men, and a few women, are able to control without any genuine scrutiny other than what appears every three months on a company earnings sheet (and even that’s unnecessarily cryptic).

Revealing moments like the one Kirkpatrick summoned from the usually robotic Zuckerberg are few and far between. The depressing accepted reality in technology journalism is that if you give a company a hard time, they’ll shut you out.

And that’s because many major technology companies guard their work with barbed wire, and wrap their executives in cotton wool.

Interactions between big tech and the outside world are orchestrated and engineered to the nth degree. On those rare occasions, even the mildest scrutiny about anything other than the new product being flogged that day is swiftly shot down with tech’s unofficial motto.

“Sorry… but that’s not what today is about.”
Unprecedented power

So what, you might think. So what if technology companies want to keep their affairs to themselves -  it’s not a public service or anything.

You might also think that this is a technology journalist throwing his connected toys out of his smart pram -  and for the most part you’d be right, I’m not ashamed to say.

But what Facebook’s challenges over fake news reveal, I think, is that we’re in completely uncharted territory.

Never has any private company had such immediate power over the way we act, feel, think, date, buy, fight - whatever.

And it’s impossible, if you plan on living in the modern world, to avoid Facebook or Google.

Even if you never create a Facebook account, your browsing habits will be logged when you visit pages that contain the Facebook ‘like’ button. Google’s near-$500bn value is made up almost entirely from selling advertising, which is why they’re absolutely everywhere on the internet. It’s the scale that makes the money.

How the internal cogs of these sites work is a complete mystery. My colleague Rory Cellan-Jones’ recent radio documentary into Google summarised that its algorithm was so complex that no single person could possibly grasp how it worked.
At odds

This situation, this imbalance, will surely not be able to last much longer. While technology bosses, Zuckerberg in particular, talk about their “mission” to “connect the world”, we do know that under their watch unacceptable things do take place.

Thanks to whistleblowers and investigative journalists, for instance, we know that Google at one time scooped up private wi-fi data from homes as it carried out its 

Street View trips. We know that Facebook knowingly manipulated News Feeds in an attempt to alter users’ emotions.

You can see how both of those examples could have seemed harmless -  or at least fascinating - to the engineers involved.

But what they demonstrate is that what may seem a bright idea for the tech sites may be directly at odds for what is good for the users themselves.

One person in agreement with this is Zuckerberg, in 2009 at least. That was when Facebook was at around 200m users, and he posted a video message (in a shirt and tie!) saying how he wanted users to have a bigger say in how the site is governed.

A special section -  FB Site Governance - was set up. Check on it today and you’ll see there have been no significant updates since 2012 - other than to tell people about privacy policy changes.

Soft power

Zuckerberg’s political ambitions, if he has them, are off to a very rocky start. The fake news row was a big test, and he handled it poorly -  dragging out the issue in the news agenda for well over a week.

Had he been thinking like a politician, as he now must, things could have gone differently. The new reality for Zuckerberg is that it’s no longer okay to be an awkward tech nerd. Instead he must deal with his users’ concerns with respect, and not call them “crazy”.

There’s a lot in it for him to get things right. Zuckerberg’s global ambitions will live or die on his ability to be an astute political operator. He already played a bad hand in India, where local businesses said he was harming their chances online.

If Facebook is to hit the potential of connecting the unconnected, Zuckerberg will need to think like a world leader and engage in soft power and openness in order to build, or restore, trust.

And he must stop using “increased engagement” as the key metric for Facebook’s success. What’s popular isn’t always good, and what’s good isn’t always popular.

Zuckerberg’s record on dealing with controversy has been pretty solid, and there’s of course no suggestion he has any bad intentions with Facebook.

But this week has demonstrated that it’s simply no longer enough for Zuckerberg to deny an issue and expect people to blindly take his word for it. Even if he is right, he’ll have to learn how to prove it.

Because the message the public appears to have given Zuckerberg, and perhaps all of Silicon Valley, is that when you’re unfathomably powerful, “no comment” is fast becoming not good enough.

Twitter boss sorry over white supremacist ad

Twitter logo

 Twitter chief executive Jack Dorsey has apologised after an advert for a white supremacist group appeared on the social media platform.

The advert promoted an article headlined, "The United States was founded as a white people's republic."

Mr Dorsey tweeted that the firm had "made a mistake" and blamed an automated system.

However, according to reports, Twitter had originally said a screenshot of the advert appeared to be fake.

When the ad was first brought to Twitter's attention by writer and musician Ariana Lenarsky, a spokesperson told the website Motherboard that the screenshot she provided looked "either old or photoshopped".

Ms Lenarsky said she would leave the site until the firm apologised.

"Acknowledgement from [Jack Dorsey] & [Twitter] is great, but it really isn't over," she has now tweeted.

Jack Dorsey's tweet

"We must continue to hold feet to the fire on this stuff."

The Twitter account of the group behind the ad, known as New Order, has now been suspended.

Last year, a right-wing activist claimed he had been able to promote a tweet which began "whites need to stand up for one another" using Twitter's advertising tools to target specific users, reported Slate.

This week Twitter announced new tools for tackling abuse, which includes hate speech, on its platform.

Can machines keep us safe from cyber-attack?

Terminator robot

After robot cars and robot rescue workers, US research agency Darpa is turning its attention to robot hackers.

Best known for its part in bringing the internet into being, the Defence Advanced Research Projects Agency has more recently brought engineers together to tackle what it considers to be "grand challenges".

These competitions try to accelerate research into issues it believes deserve greater attention - they gave rise to serious work on autonomous vehicles and saw the first stumbling steps towards robots that could help in disaster zones.

Next is a Cyber Grand Challenge that aims to develop software smart enough to spot and seal vulnerabilities in other programs before malicious hackers even know they exist.

"Currently, the process of creating a fix for a vulnerability is all people, and it's a process that's reactive and slow," said Mike Walker, head of the Cyber Grand Challenge at Darpa.

This counted as a grand challenge, he said, because of the sheer complexity of modern software and the fundamental difficulty one computer had in understanding what another was doing - a problem first explored by computer pioneer Alan Turing.

He said the need for quick fixes would become more pressing as the world became populated by billions of small, smart net-connected devices - the so-called internet of things.

"The idea is that these devices will be used in such quantities that without automation we just will not be able to field any effective network defence," he said.

The cyber challenge climaxes this week at the Def Con hacker convention, where seven teams will compete to see whose software is the best hacker.
Blowing up

But automated, smart digital defences are not limited to Darpa's cyber arena.

Software clever enough to spot a virus without human aid is already being widely used.

A lot of what anti-virus software did had to be automatic, said Darren Thomson, chief technology officer at Symantec, because of the sheer number of malicious programs the bad guys had created.

There are now thought to be more than 500 million worms, Trojans and other viruses in circulation. Millions more appear every day.

That automation helped, said Mr Thomson, because traditional anti-virus software was really bad at handling any malware it had not seen before.

"Only about 30-40% of all the things we protect people against are caught by these programs," he said.

For the rest, said Mr Thomson, security companies relied on increasingly sophisticated software that could generalise from the malware it did know to spot the malicious code it did not.

Added to this are behavioural systems that keep an eye on programs as they execute and sound the alarm if they do something unexpected.

Some defence systems put programs they are suspicious about in a virtual container and then use different techniques to try to make the code "detonate" and reveal its malicious intent.

"We simulate keystrokes and make it look like it is interacting with users to make the malware believe it's really being used," Mr Thomson said.
Clever code

The rise of big data has also helped spur a step towards security software that can help improve the chances of catching the 60-70% of malicious threats that traditional anti-virus can miss.

"Machine learning helps you look at the core DNA of the malware families rather than the individual cases," said Tomer Weingarten, founder and chief executive of security company SentinelOne.

The approach had emerged from the data science world, said Mr Weingarten, and was proving useful because of the massive amount of data companies quickly gathered when they started to monitor PCs for malicious behaviour.

"There is a lot of data, and a lot of it is repetitive," he said.

"Those are the two things you need to build a very robust learning algorithm that you can teach what's bad and what's good.

"If you want to do something malicious, you have to act, and that is something that will be forever anomalous to the normal patterns."

Automating this anomaly detection is essential because it would be impossible for a human, or even a lot of humans, to do the same in a reasonable amount of time.

And it is not just PCs that are better protected thanks to machine learning.

When it comes to large companies and governments, cyber-thieves are keen to lurk on their internal networks while seeking out the really juicy stuff such as customer databases, designs for new products or details of contract negotiations and bids.

It was another situation in which the machines outstripped their human masters, said Justin Fier, director of cyber-intelligence at security company Dark Trace.

"You can take a large dataset and have the machine learn and then use advanced mathematics to pull out the needle in the haystack that does not belong," he said.

"Sometimes, it will get the subtle anomaly that you might not catch with the human eye."

However, said Mr Fier, it would be wrong to think of machine learning as true AI.

It was a step towards that kind of approach, he said, but regularly needed human intelligence to make the final decision about some of the events the smart software picked out.

And, he said, the usefulness of machine learning might not lie entirely with those who used it for defence.

"We had one incident in which we caught malware that was just watching users and logging their habits," he said.

"We have to assume that it was trying to determine the most suitable way to exfiltrate data without triggering alarms.

"Where the malware starts to use machine learning is when it's going to get really interesting."

Cherry Trail VOYO A1 Plus notebook reviewed

Cherry Trail VOYO A1 Plus notebook reviewed

Review: Lenovo Yoga lookalike on a budget

A couple of months ago, Asian tech sites started talking about a new trend among Chinese tablet manufacturers. Since the tablet market was overheating, manufacturers were looking beyond tablets to ensure growth. Intel’s new 14nm processors were just what they were looking for, as they enabled them to start building inexpensive ultraportable notebooks. Many of them are marketed as “ultrabooks” but unlike proper Ultrabooks, they’re not based on “big core” processors.

At first glance, we thought the Voyo A1 Plus was just another convertible tablet, or 2-in-1. However, on closer inspection it became obvious that the Voyo A1 Plus is a Lenovo Yoga clone, which is why we started referring to it as the “Voyoga”.

The design is nearly identical; from the choice of colours to the 360 degree lid hinges. While this is an unoriginal design to say the least, it worth pointing out that Voyo found a good product to clone. As a result, ergonomics are not a problem, and the device is thin and sleek.

It may look like a Yoga, but the differences under the bonnet are huge. The Voyo is based on Intel’s new Cherry Trail Atom x5-Z8300, and this particular SKU ships with 4GB of RAM and 64GB of eMMC storage. This means it’s quite a bit slower than a proper Yoga, but it’s also quite cheap, with prices starting at about $250

Micro Bit computer becomes a commercial product

Micro Bit

The BBC Micro Bit, the tiny computing device designed to get children coding, is going on sale to the general public.

The device is already being delivered, free, to one million Year 7 children in schools across the UK.

Now it will also be available to buy from the various partners in the project for £12.99.

Commercial availability of the Micro Bit follows the signing of a licensing deal with the device's manufacturer, the Leeds-based company, element 14.

The firm says it will only sell them in batches of 90.

But retailers including Microsoft, the Technology Will Save Us organisation and Sciencescope will offer individual devices.

Facebook copy briefly surfaces in North Korea

Screengrab of StarCon social network

A clone of the Facebook social media site has briefly appeared in North Korea before quickly going offline.

Hosted on the StarCon.net.kp address in North Korea it had many of the features of other social networks.

It is not clear who created StarCon but it is thought to be a test project for a future service to be offered by the nation's telecoms operator.

Soon after being discovered, the site was hacked and it is now not accessible.

The site was spotted by Doug Madory, a researcher at network management firm Dyn, who said it was rare to see any websites hosted in the secretive nation. The site's name suggested it was linked to North Korea's Star telecom service, he said.
Parody account

StarCon was built around a commercial software package called phpDolphin and had many of the features, including newsfeeds, messaging systems and personal spaces, seen on other social sites. However, many of the site's pages were unfinished and were filled with placeholder text.

"I don't believe it was intended to be accessible from outside North Korea," Mr Madory told the BBC.

However, he said, Dyn's mention of StarCon on its Twitter feed led people to set up personal pages on the site and start using it to swap messages.

One of the first accounts created parodied North Korean leader Kim Jong-un. Outsiders created about 300 accounts on StarCon during its brief existence.
