Yahoo in recycled email privacy row

Written By Unknown on Minggu, 29 September 2013 | 23.22

26 September 2013 Last updated at 07:33 ET By Jane Wakefield Technology reporter

Yahoo email addresses reassigned to a new owner are receiving personal emails intended for the previous owner.

One man told news site Information Week that he had received emails with some highly sensitive information in them.

In June the web firm announced Yahoo addresses and IDs would be reassigned if they had been inactive for a year.

Privacy experts called on Yahoo to address the issue "immediately". Yahoo says it has taken a series of measures to overcome privacy and security fears.

"Before recycling inactive accounts we attempted to reach the account owners [in] multiple ways to notify them that they needed to log in to their account or it would be subject to recycling," a Yahoo representative told the BBC.

"We took many precautions to ensure this was done safely - including deleting any private data from the previous account owner, sending bounce-backs to the senders for at least 30-60 days letting them know the account no longer existed and unsubscribing the accounts from commercial mail."

It is also in the process of rolling out a feature called "Not My Email" where users can report an email that is not intended for them.

The process will come as little comfort to the previous owner of an email account now owned by Tom Jenkins, an IT security professional.

Mr Jenkins told Information Week: "I can gain access to their Pandora account [online radio] but I won't. I can gain access to their Facebook account, but I won't. I know their name, address and phone number. I know where their child goes to school. I know the last four digits of their social security number. I know they had an eye doctor's appointment last week and I was just invited to their friend's wedding."

Other users have revealed that they have also received messages that contain personally identifiable information.

Intimate data

"I recommend logging into your Yahoo account every six months or so in order to ensure that you retain control over it," said security expert Lee Munson.

Privacy experts said that the issues were inevitable.

"These problems were flagged by security and privacy experts a few months ago when Yahoo announced their intention to recycle old emails, and cautioned that Yahoo's plan created significant security and privacy risks. Yahoo downplayed these risks, and ignored critics, but now we see these concerns were legitimate," said Mike Rispoli, spokesman for Privacy International.

"This email recycling scheme, an effort to re-engage old users and attract new ones, is resulting in some of our most intimate data being accessed by someone we don't know and without our knowledge.

"We're talking about account passwords, contacts for friends and families, medical records - this issue needs to be addressed immediately by Yahoo if they care about the privacy of their users and want them to trust the company with sensitive information."

Taxpayers 'ripped off' on broadband

26 September 2013 Last updated at 08:00 ET By Jane Wakefield Technology reporter

The taxpayer is being "ripped off" over the cost of rolling out broadband to rural areas of the UK, MPs have said.

The Commons Public Accounts Committee (PAC) says the government "mismanaged" the project by awarding all 26 rural broadband contracts to BT.

It also said BT had "exploited its quasi-monopoly position" as the main provider.

The government defended the process as fair, while BT said it was "disturbed" by the claims which were "wrong".

'Failed to deliver'

Making sure that those living in the countryside get broadband speeds comparable to those living in towns and cities has long been something the government has grappled with.

Commons Public Accounts Committee chairwoman Margaret Hodge

Public Accounts Committee chairwoman Margaret Hodge said taxpayers had been ''fleeced''

Commercial firms such as Virgin Media and BT see little profit in rolling out services to areas with few people living in them.

So, as an incentive, the government provided a subsidy pot of £230m for firms taking on the task, with an extra £250m available after 2015, and it awarded contracts on a county-by-county basis.

Local authorities are also contributing £730m to the project, bringing the total amount of public funding to £1.2bn.

But only Fujitsu and BT entered the bidding competition, with Fujitsu later withdrawing.

BT has so far been chosen in 26 counties and is expected to win the 18 remaining contracts.

The report by the PAC criticised the government's management of the project: "The Department for Culture, Media and Sport's design of the rural broadband programme has failed to deliver the intended competition for contracts, with the result that BT has strengthened its already strong position in the market."

Continue reading the main story
  • Denmark plans to have 100 megabits per second to all by 2020
  • Estonia wants 100Mbps for everyone by 2015
  • France plans almost universal coverage at 100Mbps by 2020
  • Germany expects to have around 70% coverage at 50Mbps by 2014
  • Greece wants 100% of citizens to have access to 30Mbps by 2020
  • Ireland plans 100Mbps for all by 2020
  • Italy wants to see half of its citizens have access to 100Mbps by 2020
  • The UK's target is 90% coverage by 2017 but at the lower speed of 24Mbps

It said its contract terms were "overly generous" to BT and did not "promote value for money".

It also accused ministers of failing to check whether BT's bids were reasonably priced and said there had been "wildly inaccurate" estimates of costs.

"Local authorities are contributing over £230m more to the programme than the department assumed in its 2011 business case and BT over £200m less, yet BT will ultimately benefit from £1.2bn of public funding," the report said.

Committee chair Margaret Hodge added: "The taxpayer has been ripped off with £1.2bn going to the shareholders of BT.

"If you (the government) had devised it differently, had bigger areas for the contracts so you could spread your costs more, allowed different technologies to be used and insisted on a 100% coverage, we would have found other people in the game and I bet we would have spent less of the taxpayers money."

Media minister Ed Vaizey told BBC Radio 4's Today programme the costs were "not out of control", stressing BT was "putting up more than a third of the costs of rural broadband".

"BT is delivering under our scheme to up to 10,000 homes now; it will deliver to millions of people over the next two years with the best value-for-money, government-sponsored broadband scheme you will pretty much find anywhere in the world."

Culture Minister Ed Vaizey

Culture Minister Ed Vaizey said the broadband programme is ''very good value for money''

He said only BT and Virgin had the infrastructure to roll out the broadband, adding Virgin had not wanted to open their cable up for other companies to use - whereas many companies used BT.

Vodafone said the project would "not deliver value for money nor the rural connectivity that Britain needs", and urged the government to revise the process to encompass wireless 4G.

'Transparent from start'

BT was further criticised in the report for failing to provide local authorities with full information about where exactly it would roll out superfast broadband services, which in turn hampered rivals from drawing up alternatives.

And it was criticised for including a clause in its contract preventing local authorities it dealt with from disclosing the costs involved to other authorities negotiating contracts.

This lack of transparency meant the company "exploited its quasi-monopoly position" to limit access to both the wholesale and retail market "to the detriment of the consumer", concluded the report.

BT said it was disturbed by the report, "which we believe is simply wrong and fails to take on board a point-by-point correction we sent to the committee several weeks ago".

It added: "We have been transparent from the start and willing to invest when others have not.

"It is therefore mystifying that we are being criticised for accepting onerous terms in exchange for public subsidy - terms which drove others away."

It denied it had failed to deliver value for money for the taxpayer and said that, even with the public subsidies, it would take it 15 years to pay back its investment in rural broadband.

"Rolling out fibre is an expensive and complex business," it said.

BT's "point-by-point correction", sent to the committee on 13 August, included 83 comments responding to statements made at a committee meeting a month earlier.

It described many of the comments, on issues from the percentage of households reached to the way the contracts were awarded, as "false" and "misleading".

The report recommended the government should publish BT's detailed rollout plans so other suppliers could offer services to the final 10% of the population that would not be covered under current plans.

It said the DCMS should not spend any more money until "it has developed approaches to secure proper competition and value for money".

In 2011, then Culture Secretary Jeremy Hunt announced 90% of premises in every local authority area of the UK should have access to internet speeds above 24 megabits per second by May 2015, with a minimum of 2Mbps for others.

The process has suffered huge delays and is due to be completed in 2017, nearly two years later than planned.

But, according to Matthew Howett, an advisor at Ovum which examines the commercial impact of technology, the delays were down to the EU's failure to approve the scheme.

He said the "challenges of deploying to the most rural and remote areas of the UK shouldn't be underestimated" and that there were not many providers who could do this.

Gates calls Ctrl+Alt+Del a mistake

26 September 2013 Last updated at 10:50 ET

Bill Gates has described the decision to use Ctrl+Alt+Del as the command needed to log on to a PC as a mistake.

Originally designed to trigger a reboot of a PC, it survives in the Windows 8 operating system as the command to access the task manager toolbar and is still used in older versions to log on.

In an interview, the Microsoft co-founder blamed IBM for the shortcut, saying he had favoured a single button.

The keyboard shortcut was invented by IBM engineer David Bradley.

Originally he had favoured Ctrl+Alt+Esc, but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally so switched to Ctrl+Alt+Del because it was impossible to press with just one hand.

During IBM's 20th anniversary celebrations, he said that while he may have invented it, Bill Gates made it famous.

His involvement in the invention has made him something of a programming hero though- with fans asking him to autograph keyboards at conferences.

Finger strike

The shortcut, also known as the three-finger salute - came to prominence in the early 1990s as a quick fix for the infamous "blue screen of death" on PCs.

But speaking at a fundraising campaign at Harvard University, Mr Gates said he thought that it had been a mistake.

"We could have had a single button, but the guy who did the IBM keyboard design didn't want to give us our single button."

While some loathe the clunky command, others took to news site Reddit to express their fondness for it.

"I feel a single button would be a mistake," said one.

"There's a conscious commitment and in many cases a sense of satisfying sword play in executing the two-handed finger strike of Ctrl-Alt-Del."

Google reveals new search upgrade

Google search expert Amit Singhal outlines his vision

Google has unveiled an upgrade to the way it interprets users' search requests.

The new algorithm, codenamed Hummingbird, is the first major upgrade for three years.

It has already been in use for about a month, and affects about 90% of Google searches.

At a presentation on Thursday, the search giant was short on specifics but said Hummingbird is especially useful for longer and more complex queries.

Google stressed that a new algorithm is important as users expect more natural and conversational interactions with a search engine - for example, using their voice to speak requests into mobile phones, smart watches and other wearable technology.

Hummingbird is focused more on ranking information based on a more intelligent understanding of search requests, unlike its predecessor, Caffeine, which was targeted at better indexing of websites.

We just changed Google's engines mid-flight - again"

End Quote Amit Singhal Senior VP, Google Search

It is more capable of understanding concepts and the relationships between them rather than simply words, which leads to more fluid interactions. In that sense, it is an extension of Google's "Knowledge Graph" concept introduced last year aimed at making interactions more human.

In one example, shown at the presentation, a Google executive showed off a voice search through her mobile phone, asking for pictures of the Eiffel Tower. After the pictures appeared, she then asked how tall it was. After Google correctly spoke back the correct answer, she then asked "show me pictures of the construction" - at which point a list of images appeared.

Big payoffs?

However, one search expert cautioned that it was too early to determine Hummingbird's impact. "For me this is more of a coming out party, rather than making me think 'wow', said Danny Sullivan, founder of Search Engine Land.

"If you've been watching this space, you'd have already seen how they've integrated it into the [predictive search app] Google Now and conversational search.

"To know that they've put this technology further into their index may have some big payoffs but we'll just have to see how it plays out," Mr Sullivan said.

The news was announced at an intimate press event at the Silicon Valley garage where founders Sergei Brin and Larry Page worked on the launch of the search engine, which is fifteen years old on Friday.

At the event, the search behemoth also announced an updated search app on Apple's iOS, as well as a more visible presence for voice search on its home page.

Electronic Arts cans football game

27 September 2013 Last updated at 06:42 ET

Electronic Arts, the US games maker, says it is cancelling its college football game next year amid legal disputes over players' image rights.

The company said it was "evaluating our plan for the future of the franchise".

Student players have been seeking a share of National Collegiate Athletic Association revenues after their likenesses were used in the game.

In May, a court upheld the right of Ryan Hart, a former college player, to sue.

Mr Hart has sued for damages, saying EA should have sought his permission before using his likeness in three versions of the popular game published between 2004 and 2006.

The appeal court decided EA did not do enough to "sufficiently transform" the virtual version of the player.

Compensation

Samuel Keller, another former college football player, has also sued EA for using his likeness in the game.

"We have been stuck in the middle of a dispute between the NCAA and student athletes who seek compensation for playing college football," wrote Cam Weber, general manager of American football at EA Sports, explaining the company's decision.

Mr Weber said the company was "working to settle the lawsuits with the student athletes", and soon after publishing this statement US newspapers reported that EA had settled, but no details were given.

EA launched its most recent version of the game, NCAA Football 14, in July.

"Our decision does not affect our commitment to NCAA Football 14 and the consumers who love playing the game," Mr Weber said.

Miss Teen USA webcam hacker charged

Miss Teen USA

A 19-year-old student has been charged with hacking Miss Teen USA's webcam.

Jader James Abrahams is charged with trying to blackmail Cassidy Wolf into sending him nude photos.

He surrendered to FBI agents and faces up to two years in prison, said FBI spokeswoman Laura Eimiller.

Last month, Ms Wolf told NBC's Today show that she had received an anonymous email in which the sender claimed to have stolen images from the beauty queen's computer camera.

The sender of the email threatened to make the images public unless she would provide nude pictures of herself, Eimiller said.

Miss Teen USA

Ms Wolf, 19, was crowned Miss Teen USA in August.

Abrahams is accused of using malicious software to remotely operate webcams to get nude photos and videos of at least seven women as they changed clothes.

Some of these women he knew personally and others he found by hacking Facebook pages.

Continue reading the main story

I'll tell you this right now! I do not have a heart. However, I do stick to my deals. Also age doesn't mean a thing to me

Jader James Abrahams

The agent who interviewed him claims that Abrahams admitted to controlling 30 to 40 hacked computers and extorting some women.

Abrahams is studying computer science at university. He is currently on bail and only allowed to use his computer, which is being monitored, for coursework.

After getting the nude pictures he would send emails threatening to post them on their hacked social media accounts unless they either sent him more nude photos, a nude video, or logged onto Skype and followed his orders for five minutes.

Court records say that one teenager in Ireland wrote back: "Please remember I'm 17. Have a heart."

They claim Abrahams responded: "I'll tell you this right now! I do not have a heart. However, I do stick to my deals. Also age doesn't mean a thing to me!"

Blackberry loss after sales slump

27 September 2013 Last updated at 09:48 ET

Blackberry has reported a second quarter net loss of $965m (£600m) following a slump in sales.

The company warned investors last week that it would report a loss of up to a billion dollars, due to poor sales of its new smartphones.

It also announced 4,500 job cuts in a bid to stem those losses.

Earlier this week Blackberry agreed to be bought by a consortium led by Fairfax Financial, its biggest shareholder, for $4.7bn (£3bn).

Blackberry said it would continue to explore other options while negotiations with Fairfax continued.

The company's financial problems came to a head this year following disappointing sales of its new Z10 smartphone.

Sales were so poor that Blackberry had to write off $934m in the second quarter to account for the weakness.

Disappointment

Released in January - after many delays - the phone has failed to enthuse consumers.

The firm reported total sales of $1.6bn compared with $3.1bn in the same quarter of 2012, a near 50% fall.

"We are very disappointed with our operational and financial results this quarter and have announced a series of major changes to address the competitive hardware environment and our cost structure," said Thorsten Heins, Blackberry's chief executive.

In the second quarter, Blackberry said it sold 3.7 million Blackberry smartphones. That compares with 7.4 million shipments in the same period of 2012.

To put that into perspective, Apple sold nine million of its new iPhone 5S and 5C models on the opening weekend of sales.

Decay

In a research note, Colin Gillis from the brokers BGC, said the results were "startling weak".

He said the company's plan to focus on corporate customer, might fail.

"While we applaud the decision to focus on retooling the company into a niche enterprise focused business, it seems years too late.

"Just as the consumer business has crumbled, the enterprise business is also in decay in our opinion.

"Given the negative news flow from the company, enterprise customers are likely to shy away from committing to a struggling platform," Mr Gillis said.

Microsoft boss cries at send-off

27 September 2013 Last updated at 09:54 ET

Departing Microsoft boss Steve Ballmer has hosted his last company meeting - bidding a tearful farewell to employees he has worked with for 33 years.

The 57-year-old danced to Michael Jackson's Wanna Be Startin' Somethin', and declared that the company would "change the world again".

More than 13,000 Microsoft employees had queued to be a part of the annual company-wide event.

The firm has not yet announced a replacement chief executive.

Mr Ballmer will retire within the next year and will leave the company in a strategically precarious position as it looks to claw back lost ground in the mobile sector.

While at the helm, he became known for his vigorous and enthusiastic presentations in which he would routinely declare his love for Microsoft and its products.

Dirty Dancing

Microsoft staff took to social media to share details of Mr Ballmer's last appearance as boss at the event described as being more like a "rock concert".

It was held at the 17,000-capacity Key Arena in Seattle, a venue usually used for basketball and ice hockey.

Steve Ballmer at Microsoft corporate event in 2000: "I love this company"

Service engineer Bob Ulrich posted a picture on Twitter of the snaking queue outside the building.

He added: "Must be the year to go to the @Microsoft company meeting. Insane line."

Charles Naut, a project manager at the company, posted an image of the "very moving" speech on Instagram - it showed Mr Ballmer ending his talk by saying, "I've had the time of my life!" as the famous Dirty Dancing song was played out in the arena.

Too slow

The Verge reported that Mr Ballmer had tears streaming down his face as he made his last remarks, telling employees: "We have unbelievable potential in front of us, we have an unbelievable destiny. Only our company and a handful of others are poised to write the future.

"We're going to think big, we're going to bet big."

He took aim at some of the company's rivals, calling Apple "fashionable" and Amazon "cheap". He said Google was focused on "knowing more", while Microsoft was about "doing more".

But it is those rivals that piled the pressure on Mr Ballmer to depart. In one recent meeting with Wall Street investors and analysts, he admitted the company had been too slow expanding into the smartphone market.

"I regret that there was a period in the early 2000s when we were so focused on what we had to do around Windows that we weren't able to redeploy talent to the new device called the phone," Mr Ballmer said.

"That is the thing I regret the most. It would have been better for Windows and our success in other foreign factors."

Yelp says quarter of reviews 'fake'

27 September 2013 Last updated at 12:03 ET

Yelp, the online directory and consumer review site, says a quarter of the reviews it receives could be fake, as businesses increasingly attempt to skew consumers' opinions.

Its automated review filter now "suppresses around 25%" of "suspicious" reviews it receives, the company said.

"Any that are fake will be swiftly filtered out," said a spokesman.

But the company admitted its system was not foolproof, and that some filtered reviews could be genuine.

Last week New York authorities fined 19 firms a total of $350,000 (£218,500) for posting fake reviews on websites.

In a year-long sting operation, the city's attorney-general's office set up a fake yogurt shop in Brooklyn and asked for help from firms offering search engine optimisation (SEO) services that can help boost companies' online presence.

Some of these firms created online profiles and then paid for reviews from freelance writers, some from the Philippines, Bangladesh and Eastern Europe.

Many businesses were also producing their own fake online reviews, the authorities discovered.

The practice is known as "astroturfing", reflecting the fact that such consumer - or grass-root - reviews are not genuine.

Fraudulent

A recent academic report found that the proportion of fake reviews submitted to Yelp had risen from 5% in 2006 to 20% in 2013.

Michael Luca of Harvard Business School and Georgios Zervas of Boston University studied the incidence of fraudulent reviews of Boston restaurants posted to Yelp, including those that had been filtered out.

After analysing more than 310,000 reviews of 3,625 restaurants, they found that negative fake reviews occurred in response to increased competition, while positive fake reviews were used to strengthen a weak reputation or to counteract unflattering reviews.

Fake reviews tend to be extremely positive or negative, they found.

"As crowdsourced information becomes increasingly prevalent, so do incentives for businesses to game the system," the authors concluded.

Yelp, which has more than 100 million unique visitors a month, expressly forbids paid reviews.

About 42 million reviews have been published on Yelp since its launch in 2004.

Valve reveals haptic game controller

27 September 2013 Last updated at 14:32 ET By Dave Lee Technology reporter, BBC News

Games developer and publisher Valve has shown off its Steam Controller, the final part of its strategy to bring its PC-based platform to the living room.

The controller offers two trackpads which provide "haptic" feedback capable of delivering various physical sensations to the player.

Valve said it offers a better way to play games that have traditionally been controlled with a keyboard and mouse.

Gamers have been invited test the device before it goes on sale in 2014.

"Traditional gamepads force us to accept compromises," the company said via its announcement page.

"We've made it a goal to improve upon the resolution and fidelity of input that's possible with those devices.

Continue reading the main story

As innovative and successful a company as Valve certainly is, they're taking some risks here.

Not least their belief that the market they're aiming for is so large. PC games, those distinct to the platform, tend to be focused on more intimate interaction, with the vast complexity of a mouse and keyboard for controls.

It's not a medium that immediately lends itself to a handheld controller from the other side of a room.

It's also worth noting that their idea is not especially novel. Media boxes, and even wheezing PC towers, already sit by a lot of people's televisions, streaming appropriate games from machines in another room, or capable of gaming themselves.

A decent portion of that perceived audience who wants to play PC from afar has likely botched something for themselves. I know I have.

For this to work, Valve is going to have to pitch some really superb tech, running in a small, super-quiet machine, at a very competitive price.

Those are a lot of factors to get right, if they want to seriously compete with the behemoths of sitting room gaming.

"The Steam controller offers a new and, we believe, vastly superior control scheme, all while enabling you to play from the comfort of your sofa."

Research and testing

The controller is the third announcement the company has made this week. On Monday, it outlined plans to create an entire Linux-based operating system for running games, and followed up on Wednesday with details of the Steam Machine, essentially a new type of games console.

The widely-anticipated controller completes what Valve will hope is a strategy that can shift gamers that use traditional PCs - which is seen as a market headed for decline - and coax them into the living room.

However, the biggest challenge the company faces in doing so is in convincing gamers who have spent years playing titles, particularly first-person shooters, by using a combination of keyboard and mouse that a handheld controller can offer a more enjoyable solution.

The company said it had spent a year researching and testing different control methods. It said the haptic feedback offered new possibilities for creating immersive gaming.

"This haptic capability provides a vital channel of information to the player - delivering in-game information about speed, boundaries, thresholds, textures, action confirmations, or any other events about which game designers want players to be aware."

The company is to send out 300 early versions of the controller to people who sign up for beta testing.

Giant owl eyes

Rob Crossley, associate editor of Computer and Video Games, has been following Valve's announcements throughout this week. He has described the latest move as "fearless".

"Controller design standards haven't changed since the first PlayStation... the D-pad, the two sticks... that's evolved only slightly over the last 20 years.

"Sure, it looks a little funny - those two giant owl eyes - but I think that this could lead to a change in the way we look at controllers."

Valve is banking on the trackpads providing the same kind of precision offered by a mouse, Mr Crossley added.

"I think they believe this is their best attempt at trying to map the precision of the mouse onto a gamepad.

"If it does pay off, if they do manage to emulate the mouse on a controller, that opens up whole new genres."

Some had speculated - somewhat hopefully - that Valve would make a surprise announcement about the next instalment in its Half-Life series.

However, there was no mention of the game in any of Valve's announcements - but many now speculate that Half-Life 3 could be a launch title for the new Steam system and controller.

"The natural thinking is surely they will show off Half-Life 3 when SteamOS is launched," said Mr Crossley.

"A lot of people are also saying that it would be exclusive to the Steam Machine - but that would be a very un-Valve-like thing to do. They've always been very open."

Weibo anger 'shared faster than joy'

Written By Unknown on Minggu, 22 September 2013 | 23.22

20 September 2013 Last updated at 04:55 ET By Melissa Hogenboom Science reporter, BBC News

Anger spreads faster online than other emotions such as joy, scientists say.

A team analysed the word choice and emoticons of people's posts on the Chinese social network Weibo and split them into the categories of anger, sadness, joy and disgust.

By analysing the influence messages had with other users, they observed angry sentiments were more rapidly shared.

However, others say this is because angry people tend to have more angry friends.

The study has been published on the Arxiv pre-print server, though it has yet to be subjected to peer review.

The team from Beihang University in Beijing says its work could give insight into how information spreads through social networks, influencing others along the way.

"Users on Weibo tend to repost angry news posted by their friends while deeper explorations still need more investigations," Ke Xu, one of the co-authors, told BBC News.

'Formation of public opinion'

"We mined the reposted angry messages and found that most of them were related to social problems in China or the diplomatic issues between China and foreign countries," he said.

Weibo had become the most convenient channel for people in China to take part in the discussion of social problems and to express their concerns. Reposting information was a "symbolic action" for expressing viewpoints.

"The angry mood delivered through social ties could boost the spread of the corresponding news, and speed up the formation of public opinion and collective behaviour," Prof Xu said.

If you are worked up about something, your followers are to a large extent likely to show the same emotion"

End Quote Thomas Jackson University of Loughborough

The team collected more than 70 million messages from 200,000 users over a six-month period in 2010 to analyse keyword topics and how many times a message was reposted.

Weibo is China's equivalent of Twitter and now has more than 500 million users, who post about 100 million updates a day.

Sadness was not quickly shared, and the authors said it required more detailed exploration to observe the underlying reasons.

Christo Wilson, a US-based researcher at Northeastern University in Boston, Massachusetts, who was not involved with the work, also undertakes analysis of Weibo.

He said that the headline result of the latest study was "slightly sensational as the research does not back this up".

Dr Wilson told BBC News: "The authors show that people who have a particular emotional disposition tend to group together and interact with each other, but whether the information will spread beyond that angry group is difficult to predict.

"The work definitely shows that accounts that tend to post angry stuff tend to group together, but from that you cannot necessarily infer the spread of information. That claim is too strong."

Map mood of nation

Social media networks now enable researchers to analyse immediately what people are saying about a range of topics.

Recently, British scientists developed a computer program that can map the mood of the nation through the use of Twitter.

They found that the emotions people expressed were closely linked to real events and could help identify early threats to public safety.

One of the team members was Thomas Jackson, of the University of Loughborough. He said of the Weibo study that there was already a good body of research showing that negative emotions spread faster than positive ones.

"There are many grades of 'anger' and many ways of expressing it.

"It's pretty natural that, if you are worked up about something, your followers are to a large extent likely to show the same emotion. We normally 'follow' people like ourselves," he told BBC News.

Google revamps logo and search page

19 September 2013 Last updated at 18:23 ET By Leo Kelion Technology reporter

Google has begun rolling out a redesign of its homepage - the world's most visited web address.

The revamp features a flattened, reshaped logo and replaces the previous menu bar with a smaller range of links on the page's right-hand side.

The move comes in the same month that Yahoo's logo and Microsoft's Bing search tool have also been updated.

A Google spokeswoman said that similar changes would now be "slowly rolled out" across its products.

A blog post added that the firm intended to "streamline" users' experience of its services to prevent "distractions".

It is the first change to Google's logo since 2010. Not all users will be able to see the redesign yet.

"This is the season for consumer tech updates and whether you sell a product or it's free everyone wants to look fresh ahead of the Christmas shopping season," said Sarah Rotman Epps, an analyst at the tech consultancy Forrester.

"What they are doing is actually pretty subtle and that's because these software companies depend on user loyalty - they don't want to do anything that would alienate their customers."

Another analyst suggested that cutting down the number of links would encourage people to use Google's social network, Google Plus.

To reveal other products - such as Google Drive storage, YouTube videos or the Android app Play Store - visitors to the firm's search page must now click on an icon made up of small squares.

"I do think that there is a move to try to make Google+ more central to everything its users do," said Carolina Milanesi from the tech advisors Gartner.

"It might be the case that it is not obvious to some people that they need to click on the box to reveal the firm's other services."

Cyber-blackmailers 'abuse hundreds'

20 September 2013 Last updated at 07:22 ET

Hundreds of British children are being blackmailed into performing sex acts online, the Child Exploitation and Online Protection Centre has warned.

Abusers posing online as children talk victims into sexual acts or sharing of images, then threaten to send pictures to the child's family and friends.

Ceop said in 12 cases over two years, 424 children had been blackmailed in this way - 184 of them in the UK.

Deputy chief executive Andy Baker said the abuse "escalates really quickly".

He told BBC Radio 4's Today programme that it could take as little as four minutes "to go from, 'Hi, do you want to get naked?', to self-harming".

Seven victims have killed themselves, including a 17-year-old in the UK.

Another seven seriously self-harmed, of whom six were from the UK.

Mr Baker said: "We're talking about a very small dark percentage of [the internet] and this is what we need to police".

Daniel Perry, from Dunfermline, Fife, took his own life in the summer after blackmailers demanded thousands of pounds having tricked him into thinking he was chatting with a US girl.

'Slave-like acts'

He was told that his video conversations would be spread among friends and family unless he paid cash. Other victims have been told their activities would be shared unless they performed more extreme acts.

Continue reading the main story

Of all the recent developments involving the internet this is one of the most disturbing.

The perpetrators are usually calculating, computer-savvy men aged between 20 and 44; some act alone, others as part of an organised network. Their motives are more than just sexual - they want control, and in some cases money.

The victims are girls and boys, unwittingly drawn into the paedophiles' net by the possibility of friendship or consensual sexual contact.

Adolescents are particularly vulnerable as it's natural for them to explore their emerging sexuality or engage in risky behaviour - but few can imagine the dangers that their innocent internet chat may lead to.

As well as catching the offenders, investigators say children and parents must be made aware of the risks.

In the 12 cases highlighted by Ceop, the abusers came from four continents and in five cases the criminals were based in the UK.

Children as young as eight had been forced to perform "slave-like acts", said Mr Baker. As well as the performance of sex acts, the abuse sometimes involved being forced to self-harm and there had been a few attempts to extort money.

Experts highlighted the accessibility of the English language and foreign abusers' perceptions about the liberal nature of UK society as reasons for the targeting of British children.

Mr Baker said thousands of British children could have been approached in attempts to instigate abuse.

While only a handful of children will respond, thousands are exposed to the risk, he said.

Ceop operations manager Stephanie McCourt said: "First of all it's the English language. They are able to threaten the children if they can communicate to them. English is a really popular universal language.

"Second of all, the offenders have actually said that because they perceive the UK as a very free and open and liberal society, they think that they will have more success in targeting UK children."

The biggest case, known as Operation K, involved 322 children around the world being blackmailed, including 96 in the UK.

The victims were mainly boys aged 11 to 15, who were targeted by a gang from a non-European country. The suspects are due to stand trial in the coming weeks.

Fake profiles

The gang used more than 40 fake online profiles and more than 40 different email addresses to carry out their abuse.

Scott Freeman: "You need to educate your children"

The network of abuse was exposed after a social networking site noticed suspicious activity and a British child told their parents.

Set up in 2006 in affiliation with the Serious Organised Crime Agency, Ceop is a police agency dedicated to protecting children from sexual abuse.

Ceop said warning signs that a child was being subjected to online abuse could include them becoming aggressive, withdrawn, or self-harming.

But in Daniel Perry's case it appears there were no warning signs.

His mother told reporters after his death: "He was a happy laddie, not depressed and the last type of person you would think would take their life... We're a very close family and I just wished he had come to me and said something."

The apprentice mechanic had been having online conversations with someone he believed to be a girl around his own age.

Just before his death, he was warned by the blackmailers that he would be better off dead if he did not transfer the cash. Less than an hour after replying to the message, he fell from the Forth Road Bridge.

Scott Freeman, the founder of cyberbullying charity Cybersmile, told the BBC it was important for parents to educate themselves and their children about the internet - particularly online privacy settings and the procedures available for reporting incidents.

He said: "Don't talk to people you don't know, don't move from the platform onto more private platforms."

Internet providers could do more to tackle abuse, Mr Freeman said, but he added: "We've started to see some of them take responsibility now and they've started to put procedures in place so hopefully things are moving in the right direction."

Abuse can be reported to Ceop online at www.ceop.police.uk, via the NSPCC helpline's on 0800 328 0904, or to police

RSA in NSA algorithm link warning

20 September 2013 Last updated at 07:28 ET

RSA, the internet security firm, has warned customers not to use one of its own encryption algorithms after fears it can be unlocked by the US National Security Agency (NSA).

In an advisory note to its developer customers, RSA said that a default algorithm in one of its toolkits could contain a "back door" that would allow the NSA to decrypt encrypted data.

It "strongly recommends" switching to other random number generators.

RSA is reviewing all its products.

The advice comes in the wake of New York Times allegations that the NSA may have intentionally introduced a flaw into the algorithm - known as Dual Elliptic Curve Deterministic Random Bit Generation - and then tried to get it adopted as a security standard by the US National Institute of Standards and Technology.

Privacy

In the 1990s, the NSA tried to claim the right to unlock all encryption systems, but lost the battle after privacy rights and freedom of speech advocates objected.

The NSA maintains that it needs to be able to decipher encrypted communications to protect the US against terrorism and organised crime.

As the documents leaked by the former government security contractor Edward Snowden have demonstrated, the NSA has been intercepting communications data from all over the world through its Prism surveillance programme.

But it is locked in a continuous battle with cryptographers who are developing increasingly sophisticated security systems.

One of the NSA's tactics has been to persuade leading technology companies, such as Microsoft and Google, to co-operate with the security services in providing access to user data. Privacy rights campaigners have been concerned over how far this co-operation may extend.

Under US law, service providers have to hand over user data to the NSA but are not allowed to publish how many security-related data requests they receive.

A growing number of providers are beginning to stand up to the government and demand more transparency.

For example, the Digital Due Process Coalition, which is calling for reform of the 1986 US Electronic Communications Privacy Act (ECPA), includes companies such as Apple, Google, Facebook, Amazon, Linkedin and Microsoft.

The coalition argues that the ECPA has been outpaced by the rapid rise of the internet and the explosion of digital data.

Stephen Elop to receive $25m pay-off

20 September 2013 Last updated at 07:37 ET

Former Nokia chief executive Stephen Elop, will receive a $25.4m (£16m) pay-off when Microsoft's deal to buy Nokia's handset business goes through.

Under the deal, Mr Elop will receive 18 months of his salary and money from incentive and share schemes.

Mr Elop moved from Microsoft to run Nokia in September 2010 and will return to his former employer when the deal is completed.

Microsoft will fund 70% of his pay-off, which has sparked anger in Finland.

The nation's economy minister, Jan Vapaavuori, reportedly said: "I find it difficult to understand the merits of this bonus."

Earlier this month Microsoft agreed a deal to buy Nokia's mobile phone business for $7.2bn.

The purchase is set to be completed in early 2014, when about 32,000 Nokia employees will transfer to Microsoft.

Nokia shareholders are due to vote on the deal on 19 November.

In information provided for shareholders ahead of that meeting, Nokia explained in detail Mr Elop's compensation.

When the deal with Microsoft was signed on 3 September, Mr Elop agreed to step down as Nokia chief executive and take a new job at Microsoft when the deal is completed.

Due to that change Nokia says that he is entitled to 18 months of his salary and what Nokia describes as a "management short term cash incentive" which combined are worth $5.7m.

He is also entitled to share awards worth $19.7m.

Strategy change

When Mr Elop took charge at Nokia in September 2010 he became the first non-Finn to run the company.

In February 2011, he sent a warning memo to staff describing Nokia as a company standing on a "burning platform" surrounded by innovative competitors who were taking its market share.

Mr Elop decided that the company should abandon its own operating software for smartphones and instead use Microsoft's technology.

The first phones were launched in September 2012, but have failed to reclaim market share from Apple and smartphones running Android software.

Eight held over £1.3m bank heist

20 September 2013 Last updated at 08:42 ET

Eight men have been arrested in connection with a £1.3m theft by a gang who took control of a Barclays Bank computer.

The money was transferred from the branch in Swiss Cottage in north London in April, a Met Police spokesman said.

Searches are being carried out at addresses across London where property including cash, jewellery, drugs and credit cards has been seized.

The raid is being linked to an attempt to steal from Santander last week.

Four men have appeared in court charged with attempting to take control of computers at a Santander branch in Surrey Quays, south-east London.

Det Supt Terry Wilson said the Barclays investigation was being carried out by the same police team.

However he said the latest arrests "are a different level, it's really the top tier of this criminal network that have been arrested".

He added: "This was a highly-organised criminal network with each individual filling a specific role.

"All criminal networks have a head and we very much believe we have now apprehended our 'Mr Big' as part of this operation."

The men, aged between 24 and 47, were arrested on Thursday and Friday.

Following the report of the theft, police found a "keyboard video mouse" (KVM) switch attached to one of the branch's computers.

It had had been placed there by a man purporting to be an IT engineer the day before the theft on 5 April.

Infiltrate and exploit

A KVM switch, which has a 3G router attached, allows a user to control multiple computers. This enabled the gang to remotely transfer funds to other back accounts.

Barclays said it was able to recover a "significant amount" of the stolen money.

One central London premises which has been searched was described by detectives as the "control" centre for the fraudsters.

"Those responsible are significant players within a sophisticated and determined organised criminal network, who used considerable technical abilities and traditional criminal know-how to infiltrate and exploit secure banking systems," Det Insp Mark Raymond of the Met's Central e-Crime Unit said.

Alex Grant from Barclays said: "Barclays has no higher priority than the protection and security of our customers against the actions of would-be fraudsters.

"We identified the fraud and acted swiftly to recover funds on the same day. We can confirm that no customers suffered financial loss as a result of this action."

Vigilante case sex abuser jailed

20 September 2013 Last updated at 12:09 ET
James Stone

Please turn on JavaScript. Media requires JavaScript to play.

Video filmed by Letzgo Hunting showed them confronting James Stone

A child abuser from Nottingham who was confronted by anti-paedophile activists has been jailed for eight years.

Nottingham Crown Court heard James Stone, 24, of Upper Parliament Street, admitted seven offences including sexual activity with a child.

Stone was filmed by a group called Letzgo Hunting after members posed as a schoolgirl during web chats.

But police said the footage played no part in the case and they acted after the victim's mother contacted them.

Letzgo Hunting said they became involved after the 15-year-old girl's mother came to them over grooming concerns.

Posing as a 14 year old, the group swapped messages with Stone in which he admitted engaging in sexual activity with the girl.

'Wanted my mum'

Members then confronted Stone at the pub where he worked.

Police said he admitted posing as a 16-year-old boy in an online chat room in a bid to contact the girl.

Violence wasn't necessary because you had groomed her so well"

End Quote Judge Joan Butler QC

When the conversation moved to instant messaging, he took her to his flat where she was manipulated into performing sexual acts.

Stone pleaded guilty in court to meeting a child following sexual grooming, two counts of sexual assault with a child, one count of sexual activity with a child, two counts of possession of indecent photographs of a child and one count of possessing an extreme pornographic image.

The CPS said that as he admitted his guilt early in the proceedings, no evidence from Letzgo Hunting was presented in court.

Prosecuting, Tina Dempster told the court Stone had asked the girl for sexual photos of herself and when they met in March had led her to believe they would be going to a cinema or restaurant.

She added: "They sat and watched films on his bed before he forced her to perform sexual acts on him.

"The girl said she was scared and too frightened to say too much."

'Hiding in phone'

In interviews the teenager told police: "He hadn't respected me or anything. I felt numb. I didn't know what to do. I was frightened. I just wanted my mum at the time."

In mitigation, Adrian Langdale said Stone had "suffered a trial by public jury in many ways" after video footage of him from Letzgo Hunting was put online.

He added: "Already his name has been made widely public.

"He has been pilloried from the beginning to the end and he has been incarcerated for his own protection because of threats from the group and other individuals."

Sentencing him, Judge Joan Butler QC said Stone had taken advantage of a girl lacking in self-esteem and "went about a campaign of grooming".

"I accept you didn't force her and you didn't use any violence but that wasn't necessary because you had groomed her so well," she said.

"An organisation became involved and got in contact with you and pretended to be young girls. You were grooming them in the same way as you had groomed the complainant in this case."

Speaking after sentencing, police cautioned against vigilante activity.

'Hunting suspended'

A spokesperson for Nottinghamshire Police said: "We're seeing a worrying increase in those who think they can take the law into their own hands when it comes to these types of internet grooming cases.

"Posting videos online of alleged offenders not only risks the safety of that person and their family, but can also compromise any subsequent criminal proceedings."

Det Insp Martin Hillier from Nottinghamshire Police, who led the case, said it was important for people to report offences such as Stone's to the police.

He added: "James Stone not only preyed upon his young victim under the guise of a schoolboy, he did it in the family home and during school time, under the noses of the adults in her life, because James Stone was hiding in her mobile phone.

"He groomed and manipulated her into doing things she would never do, before luring her to his home and taking advantage of her in the very worst way."

Letzgo Hunting previously denied any blame for the death of Gary Cleary, who was found hanged at his Leicestershire home on 13 May after the group gathered evidence he was a sex offender.

On Thursday, Letzgo Hunting put a statement on its Facebook page that it had "suspended all hunting activity" indefinitely.

An Inside Out documentary on Letzgo Hunting will be broadcast on BBC One in the Midlands on Monday 23 September at 19:30 BST.

Microsoft boss admits phone failings

20 September 2013 Last updated at 13:05 ET

Microsoft boss Steve Ballmer, who has announced he will be stepping down, admitted his company was too slow to react to the smartphone era.

The chief executive was talking to an audience of Wall Street investors and analysts.

He blamed a focus on developing its Windows operating system for letting mobile opportunities slip by.

However, he said the company now has significant opportunities in the market.

The firm has recently purchased the mobile phone unit of Nokia, a move that will allow it to speed up development on its Windows Phone platform.

The market is currently dominated by products from Apple, with its iPhone and iPad, and Google's Android platform which is used by many manufacturers such as Samsung and LG to power their devices.

Microsoft, by comparison, is a very distant third.

Surface tension

"I regret that there was a period in the early 2000s when we were so focused on what we had to do around Windows that we weren't able to redeploy talent to the new device called the phone," Mr Ballmer said.

"That is the thing I regret the most. It would have been better for Windows and our success in other foreign factors."

On the plus side, Mr Ballmer said, from the Windows Phone's "almost no share" position the only way was up.

On Monday, the company will unveil the second generation of its Surface tablet.

The first Surface, released in October 2012, has sold poorly.

In July the company said it had written off $900m (£560m) in unsold Surface stock.

Mr Ballmer admitted at the time: "We built a few more devices than we could sell."

It was widely speculated that the failure accelerated Mr Ballmer's departure from the company, which will happen within 12 months. A successor has not yet been announced.

Apple fingerprint ID security fears

20 September 2013 Last updated at 13:28 ET

A senior US senator believes the fingerprint recognition technology featured in Apple's new iPhone 5S raises "substantial privacy questions".

Senator Al Franken, chairman of the influential Senate Judiciary Subcommittee on Privacy, Technology and the Law, has written to Apple boss Tim Cook explaining his security concerns.

After stealing someone's thumbprint, hackers could "impersonate you for the rest of your life," he wrote.

Apple has yet to comment on the letter.

Mr Franken wants answers to a number of questions, such as:

  • whether the fingerprint data stored locally on the mobile phone chip in encrypted form could ever be stolen and converted into digital or visual form that would be usable by hackers or fraudsters
  • whether the iPhone 5S transmits any diagnostic information about the Touch ID system back to Apple or any third parties
  • how well customer fingerprint data will be protected and kept private
  • the exact legal status of such fingerprint data.

Mr Franken has asked Apple to answers his questions within a month of receiving his letter.

Meanwhile, hackers are gearing up to try to crack Apple's Touch ID technology.

The website istouchidhackedyet.com, set up by Nick DePetrillo and Robert Graham, lists a number of people offering rewards - including one for $10,000 from IO Capital, a venture capital company - "to the first person who can reliably and repeatedly break into an iPhone 5S by lifting prints (like from a beer mug)."

Other rewards include a bottle of wine and a book of erotica.

Blackberry to cut 4,500 global jobs

20 September 2013 Last updated at 17:43 ET

Please turn on JavaScript. Media requires JavaScript to play.

The BBC's Michelle Fleury says Blackberry "was once a pioneer" in the smart phone field

Blackberry has announced it is planning to cut 4,500 jobs, or 40% of its worldwide workforce, in an attempt to staunch huge losses.

The smartphone maker said it anticipated a loss of as much as $995m (£621m) when it reports its second-quarter earnings next week.

Shares in the firm closed down 17% after briefly being halted following the announcement.

In August, the Canadian company said it was evaluating a possible sale.

In a statement on Friday, Blackberry's chief executive Thorstein Heins said: "We are implementing the difficult, but necessary operational changes announced today to address our position in a maturing and more competitive industry, and to drive the company toward profitability."

"Going forward, we plan to refocus our offering on our end-to-end solution of hardware, software and services for enterprises and the productive, professional end user."

'Off a cliff'

The company said the losses were primarily attributable to disappointing sales of its new Z10 model smartphone.

Released in January to much fanfare after many delays, the phone has failed to enthuse consumers.

In June, Mr Heins said that the company had shipped only 2.7 million Z10 phones out of 6.8 million total. Many Blackberry users had instead opted to stick with earlier models.

Over the summer, word trickled out the company had hired a series of advisors to help it explore options.

In August, board member Timothy Dattels was appointed to a committee that would consider different business models, including a potential sale.

"We believe that now is the right time to explore strategic alternatives," said Mr Dattels at the time.

Analysts have long indicated that Blackberry's trove of patents could be attractive to potential buyers, but none of the large technology companies have publicly indicated interest.

"The company has sailed off a cliff," BGC technology analyst Colin Gillis told the BBC.

Continue reading the main story

"This is the quarter where Blackberry as you used to know it is no longer."

Mr Gillis said the job cuts and losses today could dampen the enthusiasm of potential buyers and might indicate the company could not find any interested parties.

This week, the company released a new version of its handset, the Z30, which was praised by observers but was nonetheless overshadowed by Apple's launch of its new smartphone products.

"It's not a bad phone," said Mr Gillis.

"I'm sure they'll sell at least one."

Wave power pistons bag Dyson award

Written By Unknown on Minggu, 15 September 2013 | 23.22

12 September 2013 Last updated at 17:02 ET By Mark Ward Technology correspondent, BBC News

A wave power generator that can harvest energy no matter which way the sea is running has won the UK round of James Dyson's engineering award.

The Renewable Wave Power generator seeks to overcome the limitations of some current wave power technologies.

These work best when struck by waves travelling in one direction and are less efficient in more turbulent seas.

The generator uses loosely coupled pistons to reap power from tidal waters that flow unpredictably.

British sea power

The win means that Sam Etherington, who created the generator, gets £2,000 to create a bigger prototype that will undergo tests in water tanks to prove its efficacy.

The engineering graduate studied mechanical design at Brunel University in London, and now lives in the Lake District.

Mr Etherington said some of the inspiration for the design came when he was kite surfing off the coast of Cumbria in seas where waves rarely travelled in a predictable fashion.

To harness the energy that abounds in such restless waters, Mr Etherington came up with a design that uses a long chain of loosely linked enclosed pistons. Energy is generated as the chain of generators flexes in the peaks and troughs of each wave.

"The ocean is a harsh and unpredictable environment," said Mr Etherington. "It is better to work with the forces than to repel them."

He added that the hard part of the development work was finding ways to replicate the chaotic seas that the generator can make best use of. Data taken from buoys moored in the Orkney Islands was used to make waves in a water tank at Lancaster University and prove the prototypes could generate power in such conditions.

Dr David Forehand from the Institute for Energy Systems at Edinburgh said existing tidal and wave power systems used different methods to cope with the ways water can move.

Systems sited in shallow waters benefitted from the fact that waves "refract" as they approached the shore, he said. This meant the wave crests tended to line up parallel to the shore before they break, making it straightforward to harvest some of their energy.

Expensive

By contrast deeper water systems, such as the Pelamis pipe generators, tended to be "loosely moored" so they can swing into the direction of dominant waves.

He added that seas can sometimes have a number of dominant wave directions and Mr Etherington's multi-axis device might be good for such situations.

"The real test for a device is its cost of energy," Dr Forehand said, adding that the complexity of the multi-axis device and its ability to withstand large seas might make it an expensive way to generate power.

The cash award will allow Mr Etherington to conduct more tests and enrol his device in European trials for fledgling tidal power systems.

Mr Etherington's project was one of 63 in the UK selected by the judges on the James Dyson panel to compete for the UK prize.

His project now goes through to the international final where a cash prize of £30,000 is up for grabs.

For this year's competition, engineers in 18 countries have submitted more than 650 entries.

Samsung backs 64-bit smartphones

12 September 2013 Last updated at 19:01 ET By Leo Kelion Technology reporter

Samsung has confirmed its next high-end smartphones will feature 64-bit processors.

The announcement follows the launch of the iPhone 5S, the first handset to include the technology.

Apple boasted its A7 chip offered "desktop-class architecture".

However, experts say most apps are unlikely to see much immediate benefit from the shift from 32-bit tech and that it could introduce compatibility problems in the future.

The Android operating system would need to be updated before Samsung's Galaxy devices could take advantage of a shift to 64-bit.

Faster work

The number of bits in relation to a microprocessor affects the size of the numbers that can be handled by its registers - the tiny bits of memory on the processing chip itself. Those numbers are then used to address RAM (random-access memory).

In the case of 32-bit architecture, the amount of memory than can be addressed is two to the power of 32, in other words 4.3 billion values.

In the case of 64-bit architecture the processor can theoretically address 18,400,000 trillion values.

As a result, operating systems written for 32-bit chips can only access up to 4GB of RAM, but those written for 64-bit processors can, in theory, support up to 16 billion gigabytes of RAM.

Continue reading the main story

When app makers do decide to transition to fully 64-bit, it will create a divide in the market"

End Quote Chris Green Davies Murphy Group

If a program has been written to take advantage of a 64-bit operating system, it should mean the processor can access data that is in this larger memory rather than retrieving it from, for example, the hard disk.

This speeds up the whole processing chain.

However, including more RAM also makes the equipment more expensive and power-hungry.

For that reason, smart-device makers have tended to shy away from taking advantage of 32-bit chips' upper RAM limit.

Samsung's forthcoming Galaxy Note 3 handset goes the furthest, with 3GB of RAM. The device also features a bigger-than-normal 3,200 mAh battery.

Incompatible apps

Samsung Electronic's co-chief executive announced its plan to use 64-bit chips, in an interview with the Korea Times newspaper.

"Not in the shortest time," said Shin Jong-kyun. "But yes, our next smartphones will have 64-bit processing functionality."

However, bearing in mind there will remain many iOS and Android handsets on the market that still rely on 32-bit chips, this may deter developers from taking advantage of the switch in the short-term.

"People who have the old 32-bit processors will not be able to run software that is built specifically for the 64-bit processors because the latter uses a different instruction set," explained Prof Alan Woodward, from the University of Surrey's computing department.

"However, if people write in 32-bit, it will run on many of the 64-bit processors because they still support the old instruction set.

"So, you can get the whole market by writing the app in 32-bits, but you can only get a very small part of the market if you write specifically for 64-bits."

One solution to this is to use what is called a "fat binary", a program containing code tailored to both types of processor. However, apps that do this become bigger and therefore take up more storage space.

Once sales of the new devices do grow, makers of video games and software to create 3D-animations might be among the first to make the switch since their programs are among the most processor-intensive and thus most likely to see the biggest benefit.

One iPhone and Android developer welcomed the move.

"Yes, many apps won't be able to take advantage of 64-bit at the outset," said Stephen Lum from Visual Candy Apps.

"But the beauty of what Apple did is that they said it takes an iOS developer, like me, two hours to convert to 64-bit. That is awesome."

However, one industry watcher warned that the switch might create compatibility problems for devices using older types of chip once developers started releasing apps that only worked on 64-bit processors.

"When app makers do decide to transition to fully 64-bit, it will create a divide in the market," said Chris Green, from the Davies Murphy Group consultancy.

"We saw exactly the same thing happen in the Windows world when software makers moved from 32-bit to purely 64-bit."

Rise of ARM

For now British chip designer ARM may prove the biggest beneficiary.

Smart-device makers are able to offer 64-bit tech because they have licensed the firm's ARMv8 architecture, which it first announced in 2011. The design includes other elements which should also boost processing power.

The news means the company will enjoy bigger fees. ARM's share price has risen about 10% since the start of the week.

Some have speculated that Apple's announcement might foreshadow the US firm ditching Intel chips in its laptops and desktop computers and moving to its own processors.

"Apple's new A7 chip is not powerful enough to be a PC chip, but the architecture is going that way," said Prof Woodward.

"They might be readying themselves. I think this is the beginning of a long road."

Audio pioneer Ray Dolby dies aged 80

12 September 2013 Last updated at 19:59 ET

Ray Dolby, the US engineer who founded Dolby Laboratories and pioneered noise reduction in audio recordings, has died in San Francisco aged 80.

Mr Dolby had suffered from Alzheimer's disease for several years and was diagnosed with leukaemia this summer.

His name became synonymous with home sound systems and cinema, and his work won many awards.

Kevin Yeaman, president of Dolby Laboratories, described Ray Dolby as a "true visionary".

Mr Dolby was born in Portland, Oregon, and grew up in the San Francisco area.

He began his career in the Ampex Corporation, helping to develop early videotape recording systems while he was still a student.

Kevin Yeaman, president of Dolby Laboratories, says Ray Dolby was "committed to excellence"

He then went on to complete his PhD at Cambridge University in England and in 1965 founded Dolby Laboratories in London.

The company grew to be an industry leader in audio technology, cutting background hiss in tape recordings and later bringing out "surround sound".

Mr Dolby moved his company to San Francisco in 1976 and in 1989 was awarded an Oscar for his contributions to cinema. He shared the award with Dolby executive Ioan Allen.

He also received a Grammy award in 1995 and Emmy awards in 1989 and 2005.

Mr Dolby's son, filmmaker and novelist Tom Dolby, said: "Though he was an engineer at heart, my father's achievements in technology grew out of a love of music and the arts.

Twitter plans stock market listing

Rory Cellan-Jones reports on Twitters rise to the stock market

Twitter says it plans to join the stock market in the most hotly anticipated flotation since Facebook's last year.

Referring to the official paperwork needed to join the market, the company tweeted: "We've confidentially submitted an S-1 to the SEC for a planned [initial public offering]."

Investors value Twitter, founded in 2006 by Jack Dorsey, Biz Stone and Evan Williams, at more than $10bn (£6.3bn).

Twitter gave no further details as to the timing or price of the offering.

The microblogging service is on track to post $583m in revenue in 2013, according to advertising consultancy eMarketer, up from $288m in 2012.

Most of Twitter's funding comes from advertising, with companies paying for "promoted tweets" that appear in users' Twitter feeds.

Advertisers are keen to target Twitter's 200 million active users, who send more than 500 million tweets a day.

Twitter's flotation was long expected, but is only likely to increase scrutiny of the company.

In recent months, it has faced criticism for not doing enough to tackle rape threats against prominent women, as well as for not having enough security measures to prevent media accounts from being hijacked. In parts of the Middle East, leaders have also accused it of being a "scourge" and a "threat to national unity" for its role in opposition protests.

The firm will be mindful of the extra scrutiny Facebook endured after its flotation. Twitter users will also be on guard against the idea that pressure from investors could see them made subject to more adverts.

Investors, meanwhile, may be concerned about churn - the idea that people join and then drop out. Innovation may be the answer to that, with Twitter's new music discovery service and ways of viewing conversations with others being possible solutions.

But some analysts believe the risk for Twitter post-flotation is that if the drive for greater advertising revenue leads to increased numbers of adverts in and around the site, they could become intrusive and unpopular with users.

"There's a few issues [such as] how many revenue streams can be developed beyond just advertising, the impact of more people accessing the service via smartphones," said Colin Gillis, a New York-based technology specialist at BGC Partners.

Nearly two-thirds of users access Twitter via mobile devices that have traditionally been difficult for advertisers to reach.

This is one reason why Twitter has acquired MoPub, a mobile-focused advertising exchange, for a reported $350m.

"Twitter was more or less a mobile-first platform from the start and so the company built its experience to work relatively well across devices," Clark Fredriksen of eMarketer told the BBC.

"Ultimately, they did a good job of monetising their mobile user base."

Learning from Facebook

"Twitter is one of the last of the major developed social networks to file [for an initial public offering or IPO] - we've already had Facebook and LinkedIn," said Mr Gillis.

Facebook listed on the stock market in May last year. Although it initially created excitement among investors, its share price performed poorly, before recovering this summer.

The timing of the IPO is likely to be related to renewed activity in stock market flotations. There have been 131 IPOs priced so far in 2013, according to IPO tracking firm Renaissance Capital - a 44% increase on the same period last year.

Activity is climbing back towards the pre-financial crisis levels of 2007, says Renaissance.

Andrew Frank, social media expert at technology research company Gartner, said: "[The IPO] gives its investors a way to get some of the money back that they put into the company at the beginning.

"It gives the employees a similar kind of event to reward them for the success they've had so far. And it gives Twitter itself extra funds to invest in new projects and innovation."

Mr Gillis said it was impossible to say how great the demand for Twitter shares would be until the company released a valuation.

Analysts say Twitter must continue to innovate under the scrutiny of public ownership.

"One of the things they will have to focus on is making sure that they keep their users very actively engaged," Nate Elliott, an analyst at the tech consultancy Forrester, told the BBC.

"One of the things Facebook has done very successfully over the past year-and-a-half has been to show that not only is the number of users growing, but that those users are becoming more active."

'This tweet is going public?'

Twitter's tweet announcing its filing immediately went viral - it was re-tweeted more than 8,000 times within an hour of its posting.

For many users, it seemed apt that the company would use its own platform to announce the news.

"Naturally Twitter announces its IPO via Twitter. What other way?" one read.

Twitter later sent a follow-up tweet, which read simply: "Now, back to work."

Once a company has filed paperwork with US regulators for a planned IPO, it enters a so-called "quiet period" when it is not allowed to speak to the media.

According to the Securities and Exchange Commission's website, a company can file a confidential prospectus for a public share sale if it is classified as an "emerging growth company" with revenue of less than $1bn.

Google Street View car in 'accident'

13 September 2013 Last updated at 08:47 ET By Zoe Kleinman Technology reporter, BBC News

A Google Street View car hit two public transport buses and a truck in the city of Bogor, Indonesia.

Police said the car driver hit the first bus, appeared to "panic" when the bus driver responded angrily, and tried to drive off.

But in doing so the vehicle hit a second bus and then the truck, according to local media reports.

It is unclear whether anybody was hurt at the scene. Google has confirmed that an incident has taken place.

"We take incidents like this very seriously. We're working closely with local authorities to address the situation," Vishnu Mahmud, head of communications for Google in Indonesia, told news agency AFP.

Pictures of the incident were posted to an Indonesian website by an eyewitness.

Donkey

The tech giant has been taking photos of the region for its mapping service since November 2012.

Earlier this year Google denied reports that one of its Street View cars had run over a donkey in Botswana.

Street View photos appeared to show the animal walking by the roadside in one shot and then lying on its side behind the car in another.

"Because of the way our 360-degree imagery is put together, it looked to some that our car had been involved in an unseemly hit-and-run, leaving the humble beast stranded in the road," wrote Kei Kawai, Group Product Manager, Google Maps in a blog post at the time.

"The donkey was lying in the path - perhaps enjoying a dust bath - before moving safely aside as our car drove past.

"I'm pleased to confirm the donkey is alive and well," he added.

'Cyber plot' to steal from Santander

13 September 2013 Last updated at 09:02 ET

Twelve men have been arrested over an "audacious" alleged plot to steal millions of pounds from a bank by remotely taking control of a computer.

A bogus engineer fitted a device called a keyboard video mouse to a machine in the Surrey Quays branch of Santander, south-east London, which would have enabled a gang to download data.

The police arrested the men on suspicion of conspiracy to steal.

End Quote Det Insp Mark Raymond Metropolitan Police

A spokesman said the "significant" plot could have netted millions of pounds.

Santander said a man pretending to be an engineer had tried to fit the device to one of their computers.

Several addresses in Hounslow, Brent, Hillingdon, Westminster, Richmond and Slough were searched and property was seized.

The arrested men, aged between 23 and 50, were detained in London on Thursday and remain in police custody.

'Organised network'

The Metropolitan Police said its "time-critical, dynamic response" had thwarted a "very significant and audacious cyber-enabled offence".

What is a KVM device?

A KVM switch (keyboard video mouse) typically allows a person to control a number of different computers from a distance.

Potentially, a hacker using a KVM can switch between different computers, see what is being displayed on the monitors, and control the computers using a remote keyboard and mouse.

Police have not said yet whether the Santander KVM was connected to internal systems, to be controlled from another part of Santander, or whether the device was connected to the internet.

The force said the operation had helped avoid "multimillion-pound losses" from the branch at the shopping centre.

A KVM (keyboard video mouse) device was fitted to a computer within the bank but was not operational, officers said.

The device, if operational, would have allowed data and contents of the desktop to be downloaded over the network.

Although it is not the first time police have seen the device used, a Met spokesman said it was the first time it had been used by "an organised criminal network".

Det Insp Mark Raymond said: "This was a sophisticated plot that could have led to the loss of a very large amount of money from the bank, and is the most significant case of this kind that we have come across.

"I would like to thank our partners from the industry who have provided valuable assistance throughout this investigation."

'No money risked'

A spokesman for the bank said: "Through this co-operation, Santander was aware of the possibility of the attack connected to the arrests.

"The attempt to fit the device to the computer in the Surrey Quays Branch was undertaken by a bogus maintenance engineer pretending to be from a third party.

"It failed and no money was ever at risk. No member of Santander staff was involved in this attempted fraud."

A bank spokesman added that Santander was aware it was a target and it had been working with the police for three or four months before the bogus engineer attempted to connect the device.

The shutters of the branch in Surrey Quays were down on Friday and several customers were queuing to use the ATMs outside branch to check their accounts.

UK pirates face copyright crackdown

13 September 2013 Last updated at 10:28 ET

Criminals making money from copyright theft are facing a crackdown in the UK.

The City of London Police launched a unit on Friday dedicated to pursuing serious intellectual property crime.

Detectives arrested two men suspected of importing £40,000 worth of counterfeit DVD boxsets in Birmingham on Friday morning.

Police will liaise with international agencies to tackle digital copyright infringement in the physical production and sale of counterfeit goods.

The Police Intellectual Property Crime Unit (Pipcu) will receive £2.56m funding over two years from the UK government body the Intellectual Property Office.

"Our focus will be the professional criminals using intellectual property crime to generate illicit gains," Det Ch Supt Oliver Shaw told the BBC.

The police will use links at national and international level to pursue suspects, building on existing contacts at agencies such as the FBI and the Department of Homeland Security in the US.

Officers trained in online investigations will act on tip-offs from industry groups to identify UK suspects, and will proactively seek out websites offering illegal goods and downloads.

Website control

The 19-strong unit will have the power to seize goods and assets, and will push internet service providers to take down websites selling spurious products.

Legitimate advertisers unwittingly running ads on illegal websites will be informed to stop advertising payments and disrupt revenue to crime gangs.

The team will also investigate the physical production and sale of counterfeit goods, for example, by pursuing criminals making faked brands of car tyres, said Det Ch Supt Shaw.

The two men arrested in Birmingham were suspected of importing and selling thousands of illegally produced DVD boxsets, the Metropolitan Police Service said in a statement.

UK efforts to counter serious copyright crime include the appointment of an intellectual property adviser by Prime Minister David Cameron.

Conservative MP Mike Weatherley, who will advise the prime minister on enforcement, was appointed on Thursday.

Regulator Ofcom published a report on Wednesday that said almost a quarter of UK downloads infringe copyright.

British Gas online services back up

13 September 2013 Last updated at 11:32 ET

Customers of British Gas were unable to log on to their accounts online to pay bills or submit meter readings for several hours on Friday.

A link on the company's website to its official blog also directed people to a blank page.

The energy firm apologised for the service - which was resumed at 15:00 BST - being down.

A spokesperson did not give an explanation for the downtime in a statement sent to the BBC.

"Although the website is accessible, customers are unable to log in to their personal services at the moment. We apologise to our customers and we are working hard to get this resolved as soon as possible," he said.

"We're investigating the reasons as we fix it."

On the UK-based website's customer log-in screen an error message said "important upgrades" were under way, but this was not mentioned on the company's Twitter feed or elsewhere.

British Gas says the website and mobile apps should now be working normally.

Microsoft offers $200 for used iPads

13 September 2013 Last updated at 13:32 ET

Microsoft has launched a US marketing offer for people to exchange "gently used" iPads for Microsoft products such as Surface tablets.

The company is offering at least a $200 token to go towards products such as the Surface RT and the Surface Pro.

Microsoft is far behind Apple in terms of global tablet sales and market share.

One US-based analyst expressed doubts that many people would swap their iPad for a Microsoft product.

"Do I think that many people will take [Microsoft] up on this offer? In a word, no," said Gartner mobile device analyst Van Baker. "The app ecosystem is the problem for Microsoft and this offer doesn't fix that problem."

There was a far greater range of mobile apps available for iPads than for Windows devices, giving Apple a competitive edge, said Mr Baker.

Microsoft has been engaged in an aggressive US marketing campaign to try to tempt Apple iPad users to buy Windows-based tablets.

In May, Microsoft launched an iPad v Windows comparison website, coupled with head-to-head advertising campaigns.

Microsoft has experienced problems trying to sell Surface devices.

In the first quarter of this year, Apple shipped 19.5 million iPads, compared with 900,000 Microsoft tablets.

In the second quarter, Microsoft shipped only 300,000 Surface devices, technology publication CiteWorld said.

Although Microsoft announced a revenue of $853 million on Surface sales in its latest financial regulatory filing, the company took a $900 million loss after failing to shift Surface RT devices.

Microsoft's $200 (£150) gift certificate offer is valid in its bricks and mortar stores. A Surface RT tablet costs $349, and a Surface Pro retails at $799.

Argentine teenage 'superhacker' held

13 September 2013 Last updated at 19:33 ET

Police in Argentina have arrested a 19-year-old man accused of heading a gang of hackers who targeted international money transfer and gambling websites.

Dubbed "the superhacker", the teenager was making $50,000 (£31,500) a month, working from his bedroom in Buenos Aires, police say.

The arrest operation shut down the power to the entire neighbourhood to prevent the deletion of sensitive data.

Police say it took them a year to close in on the teenager.

The young man lived with his father, a computer expert, in Buenos Aires.

In the teenager's room, officials found high-capacity computers.

The hackers allegedly used malware attacks to build up a network of thousands of zombie computers, which were then used to illegally divert money from accounts leaving virtually no trace behind.

The police operation included five raids in the capital and the city of Rosario, about 300km (190 miles) north.

The young man is being accused of three crimes, and if convicted of all, could be sentenced to more than 10 years in prison.

Shops and cafes fight US patent trolls

Written By Unknown on Minggu, 01 September 2013 | 23.22

30 August 2013 Last updated at 09:03 ET

The Internet Association is among a group of US trade bodies behind a new campaign calling for politicians to take action over patent trolls.

Patent trolls take out generalised patents, often on widely available technology, and then demand money from companies who use or offer it.

Shops and restaurants have been targeted for displaying QR codes and online store-locators, say the groups.

The radio and print adverts will appear in 15 US states.

"Patent trolls don't make anything, they just get rich," is a line from the Stop Bad Patents campaign, which claims that businesses can find themselves facing demands for $100,000 (£65,000) to settle - a considerable sum but often cheaper than defending themselves in court.

Its organisers want voters to contact their Congress representatives asking them to "stop bad patents, stop the trolls".

'legalized extortion'

It is a joint initiative between the Internet Association, the National Restaurant Association, the National Retail Federation and the Food Marketing Institute, all of whom say their members are increasingly being targeted.

"Patent trolls use bad patents to bully companies of all sizes, in every economic sector, from coast to coast," said Michael Beckerman, President of The Internet Association.

"This is essentially legalised extortion, forcing hard-working businesses to go to court or write a cheque."

US President Barack Obama has already called on Congress to tackle the problem of people facing legal action over commonly used technology from others who belatedly take out patents on it.

Speaking to the BBC earlier this month, Alan Schoenbaum, general counsel at the cloud computing firm Rackspace, explained that patent trolls are often "entrepreneurs or finance people" rather than genuine inventors of new technology.

"Defending a lawsuit is extremely expensive... they play on that fear that the defendant is going to spend a lot of money to defend itself and it is simply cheaper to pay them off," he said.

However Erich Spangenberg, owner of "patent monetisation" company IP Nav, says the practice of buying patents and asserting that right is already commonplace in other industries.

"Much like an architect can design a building but does not build it, a song-writer can compose a song but doesn't have to sing it, an inventor can get granted a patent and ultimately is not forced to practise it," he responded.

Google exec poached by Chinese rival

29 August 2013 Last updated at 08:35 ET By Dave Lee Technology reporter, BBC News

One of Google's top executives is leaving the company to join up-and-coming Chinese firm Xiaomi.

Hugo Barra was vice president of product management for Google's mobile platform Android, and had been at the company since 2008.

Google confirmed his departure from the company, stating that it wished him well.

"We'll miss him at Google and we're excited that he is staying within the Android ecosystem," a spokesman said.

Lucrative investments

Mr Barra took to social network Google+ to discuss his departure.

"After nearly five and a half years at Google and almost three years as a member of the Android team - the most amazing group of people I've ever worked with in my life - I have decided to start a new career chapter," he wrote.

"In a few weeks, I'll be joining the Xiaomi team in China to help them expand their incredible product portfolio and business globally — as vice president, Xiaomi Global."

Xiaomi is a Beijing-based company that makes smartphones and other consumer electronics. They described the hiring of Mr Barra as "exciting news".

Since releasing its first handset in 2011, the company has enjoyed huge growth - now valued at $10bn (£6.5bn) thanks to two lucrative investment rounds.

Critics have accused the company of lacking in innovation and copying ideas from Western competitors.

Brin split

Mr Barra's departure coincides with reports Google's co-founder Sergey Brin is "living apart" from his wife.

News site All Things Digital wrote that Mr Brin was involved with a female Google employee who had previously had a relationship with Mr Barra.

A source told the BBC the departure was unrelated to personal issues, adding that Mr Barra had been discussing his move with Xiaomi for some time.

Mr Brin, who founded Google with Larry Page, married Anne Wojcicki in 2007. The couple have two children.

She is the chief executive of 23andMe, a biotech firm in which Google has invested $10m (£6.5m).

A spokesman for the couple told Reuters that "they remain good friends and partners" and have not yet legally separated.

Ms Wojcicki's sister, Susan, is also at Google as senior vice president in ads and commerce.

It was in Susan's garage that Mr Brin and Mr Page began their search empire, which is now worth more than $70bn, in 1998.
