Amazon unveils Kindle Fire tablet

Amazon has unveiled a colour tablet computer called the Kindle Fire.

The $199 (�130) device will run a modified version of Google's Android operating system.

Until now, the company has limited itself to making black and white e-readers, designed for consuming books and magazines.

As well as targeting Apple's iPad, Amazon is likely to have its sights on rival bookseller US Barnes & Noble, which already has a colour tablet.

The Kindle Fire will enter a hugely competitive market, dominated by Apple's iPad.

Amazon will be hoping to leverage both the strength of the Kindle brand, built up over three generations of its popular e-book reader, and its ability to serve up content such as music and video.

In recent years, the company has begun offering downloadable music for sale, and also has a streaming video-on-demand service in the United States. Those, combined with its mobile application store, give it a more sophisticated content "ecosystem" than most of its rivals.

Lower priced

Digital content has already proved itself to be a money-spinner for Amazon.

Although the company has never released official sales figures for the Kindle, it did state - in December 2010 - that it was now selling more electronic copies of books than paper copies.

Its US rival, Barnes & Noble, has also enjoyed success with its Nook devices.

In October 2010, the company unveiled the Nook Color, which also runs a version of Android, albeit with lower hardware specs than many fully featured tablets.

While the Nook Color is largely focused on book and magazine reading, some users have managed to unlock its wider functionality and install third-party apps.

The Kindle Fire's $199 (�130) price tag undercuts the Nook Color by $50 (�30) and is significantly cheaper than more powerful tablets from Apple, Samsung, Motorola and others.

It is due to go on sale on 15 November in the US, although global release dates are currently unavailable.

Google boosts Silicon Roundabout

Google is to provide office space and assistance to new technology companies in London's "Silicon Roundabout".

The company has leased a seven-storey building in the Old Street area, where many start-up firms are based.

Prime Minister David Cameron has signalled his desire to turn the area into "one of the world's great technology centres".

About 300 companies are now working in the area, according to Tech City, the body set up to promote the initiative.

Google said that the building, in Bonhill Street, would host "a range of activities, such as speaker series, hackathons, training workshops and product demonstrations" in addition to providing workspace for new companies.

The California-based company stressed that it was not moving its UK headquarters - currently in central London - to the area.

Many millionaires

Eric Van Der Kleij, chief executive of the Tech City Investment Organisation, said that partnering established technology companies with fresh talent could be beneficial to both parties.

Google's Innovation Hub may be a "creative space" - but there's no sign that its researchers will be spending any time there creating anything new.

To be fair, the company's press release stresses that is just the first stage in making its commitment to Tech City a reality.

So, yes, it's a good day for east London's technology ambitions.

But if the vision outlined by the prime minister is to be realised, then the area will need to see companies like Google, Intel and Cisco fill the lofts and warehouses around the Silicon Roundabout with engineers as well as events organisers.

<!-- pullout-links-->

"What [companies like Google] do by having a firm footing in the community is provide a channel for innovation, to partner with them and potentially even sell to them," he told BBC News.

"It accelerates the process of the entrepreneur doing a tech startup, selling for a lot of money, creating a lot of millionaires within their organisation and creating recyclable wealth - then going out to do more innovation."

Large corporations have been lending support to young entrepreneurs in the area for some time.

The nearby Tech Hub project, which offers accommodation and business support, is supported by Google, media group Pearson and software firm BlueVia.

Telecoms companies, including BR and Virgin Media are also making the area a priority for installing ultra-fast broadband connections.

The Silicon Roundabout initiative has been championed by the prime minister as a model for developing the UK's knowledge economy.

Speaking in November 2010, David Cameron said that it was possible to learn lessons from Silicon Valley in the US.

"Go with the grain of what is already there. Don't interfere so much that you smother. But do help out wherever you can.

"Help to create the right framework, so it's easier for new companies to start up, for venture capital firms to invest, for innovations to flourish, for businesses to grow," said the prime minister.

Google expects its new East London Facility to open in 2012, following a major refurbishment.

US to probe HTC&#39;s Apple complaint

A US trade watchdog will investigate a claim by Taiwanese phone firm HTC that its rival Apple has infringed its patents.

HTC filed the complaint with the US International Trade Commission (USITC) in August.

It is one of three that HTC has filed against Apple.

Apple has also accused HTC of copying its technology, and other global companies are also involved in what is being called a global patent war.

Korea's Samsung is currently fighting Apple in a number of European courts, as well as Australia.

In HTC's claim, which the US International Trade Commission (USITC) will investigate, the Taiwanese firm alleges that Apple has infringed its patents in smart phones, tablet computers and computers.

HTC is seeking to block the import of Apple products into the US.

Three pleads for spectrum share

Mobile firm Three has warned that it may begin running out of capacity in urban areas by the end of next year if spectrum auctions do not go ahead.

Networks increasingly face congestion as the demand for data soars.

Auctions to free up space for next generation mobile services are earmarked for mid-2012 although Three said that the timetable was "already slipping".

It said it was vital the firm got its fair share of new spectrum.

It also warned that its rivals may attempt to delay the process.

"There is a huge financial incentive for rival operators to delay the auction. We are worried that the other three will attempt to squeeze us out of the market," said Three chief executive David Dyson at a press briefing in London.

Ofcom is due to re-evaluate the fees operators pay for 2G spectrum once the auction is complete.

"The more that is bid for new spectrum the more operators will pay in fees for existing spectrum. They will only start paying the fees from the end of the auction so there is an incentive to delay it," explained Ovum analyst Matthew Howett.

Spectrum allocation in the UK is hugely complex. Historically O2 and Vodafone own all the UK's 2G airwaves because they were the only operators in the market when that spectrum was handed out.

While other European countries have reallocated their 2G spectrum among newer players that hasn't happened in the UK.

Earlier this year Ofcom agreed to allow O2 and Vodafone to re-use parts of the 2G network for 3G services.

While it eased capacity issues for them, it led Three to complain that the playing field for mobile operators was becoming increasingly uneven.

As a sweetener, Ofcom said that it would impose a cap on the amount of spectrum companies could win at the auction to ensure 3 remained a key player in the market.

"It has made it clear that it wants Three in the market and that it values Three's disruptive influence," said Mr Howett.

Rivals are not happy and have threatened legal action over the caps.

"They argue that it is legal state aid," said Mr Howett.

O2 is awaiting the final details of how the auction will work - expected from Ofcom in November - but did not rule out the possibility of further challenges.

"We are focused on a constructive and ongoing dialogue with Ofcom on its proposals. Even if some further consultation is required, it won't delay the availability of 4G, as the spectrum itself will not be available until 2013. The key is to get the auction right," said an O2 spokesperson.

The 4G auctions will sell off spectrum in the 800MHz and 2.6GHz bandwidths.

The first has been freed up by the switchover to digital TV and is particularly valuable to operators because its low frequency means it can cover larger areas and penetrate buildings.

Three currently has the poorest in-building coverage of all the operators.

The huge demand for data has been putting the squeeze on all networks, particularly Three, and the 2.6GHz band will help ease such issues.

Mr Dyson admitted that capacity in large urban areas such as London would begin to run out by the end of next year but he remains confident it won't affect customers.

"I believe the auction will go ahead next year and therefore congestion will not happen," he said.

"We have been assured by the government and Ofcom that distortions will be rebalanced when the auction happens," he said.

But he added that the timetable for the auction process was already slipping.

"Ofcom originally planed to come back to industry with its plans in September or October but that is now likely to be the end of the year or the beginning of the next," he said.

But Mr Howett remains convinced the delays will not affect the auction.

"It is a hugely ambitious timetable, trying to do in 18 months what took three years for 3G, but most are optimistic it can still be met," he said.

Whether rivals will take the legal action they have threatened remains to be seen but pressure will be put on them to push ahead with the process.

"Jeremy Hunt has said that he doesn't want it to be delayed and they will have him breathing down their necks saying 'don't get in the way'", said Mr Howett.

As part of its push to make data more available, Three is dropping the price of its popular all-you-can-eat data plan to �18 a month.

&#39;Smart&#39; window to save energy

A new type of "smart" window that switches from summer to winter mode has been made by South Korean scientists.

The window darkens when the outside air temperatures soar, and becomes transparent when it gets cold in order to capture free heat from the sun.

Similar windows already exist, but the researchers say their method allows for an almost instantenous switch from opaque to transparent.

This may help save more energy, the team writes in the journal ACS Nano.

"This type of light control system may provide a new option for saving on heating, cooling and lighting costs through managing the light transmitted into the interior of a house," said the scientists.

"Smart windows can prevent the inside of a building from becoming overheated by reflecting away a large fraction of the incident sunlight in summer.

"Alternatively, they can help keep a room warm by absorbing the sun's heat in winter."

New approach

The existing technology uses charged particles called ions sandwiched between panes of glass.

Electric current is then applied to switch the window from opaque to clear and back.

"Start Quote

[If] you're allowing light in much quicker, this can reduce the amount of heat loss out of houses or increase the cooling in summer"

End Quote Dr Steven Morris Technology Strategy Board

But Ho Sun Lim from Korea Electronics Technology Institute, Jeong Ho Cho and Jooyong Kim from Soongsil University decided on a different approach.

They used a special polymer, a different sort of charged particles known as counterions and solvents such as methanol.

The report states that the result was a glass that was a lot cheaper to manufacture and much less toxic than those currently available on the market.

The window is able to switch from 100% opaque to almost completely clear in a matter of seconds, said the authors.

Instantaneous switch

Although "dimming" windows already exist, it is often necessary to switch them from winter to summer mode and back manually, using additional equipment such as home-automation panels.

"Until now, the numerous technologies developed not only have been chemically unstable, prohibiting their use in long-term switching applications but have been accompanied by the use of expensive special equipment and complicated harsh processing conditions," stated the report.

Dr Stephen Morris from the UK's Technology Strategy Board said that if the new method allows the window to switch from opaque to transparent and back pretty much instantaneously, then it is going to be a real benefit in terms of energy savings.

"That would mean that you're allowing light in much quicker - and this can reduce the amount of heat loss out of houses or increase the cooling in summer," he said.

Harvard site in Syria hack attack

Harvard University has had its website hacked in what appears to be a "sophisticated" Syrian-related attack.

Along with a picture of Syrian president, Bashar al-Assad, the hacked home page showed a message saying the "Syrian Electronic Army Were Here".

A further message made terror threats against the United States and criticised its opposition to the Assad regime.

Harvard said this has been the work of a "sophisticated individual or group".

"The university's homepage was compromised by an outside party this morning. We took down the site for several hours in order to restore it. The attack appears to have been the work of a sophisticated individual or group," said a Harvard spokesman.

The website was hacked on Monday morning by what appeared to be sympathisers of President Assad of Syria, with a picture of the president in military uniform appearing in front of a Syrian flag.

This was linked to another image of Syrian national colours, with a message accusing the United States of involvement in the uprisings against President Assad.

Violence threat

It told readers: "This site has been breached to spread our message even if illegally."

The message, claimed on this webpage as coming from the Syrian Cyber Army, accused the United States of supporting a "policy of killing" in Syria.

In fragmented English, it also carried a threat of violent attack.

"Do you support the war on Syria? If you are you, as well as the following Syria's population of 23 million people. This means 23 million mobile bomb. Imagine what we could do."

A Harvard spokesman suggested there had been a pattern of a growing number of such electronic attacks.

"Recent months have seen a rise in frequency and sophistication of these attacks, with hacking groups increasingly on the offensive and targeting news media, government and education websites," said a Harvard spokesman.

"We are analysing this event and will use the findings to improve our security practices for an environment that is seeing escalating threats."

India imposes text message limit

The telecoms regulator in India has put a cap on the number of text messages which can be sent from a mobile phone.

Under the new rules, no-one will be able to send more than 100 texts in a day, officials say.

The ruling is expected to be a big relief for millions of mobile phone users who have to deal with dozens of unsolicited text messages every day.

India has made several attempts in the past to rein in tele-marketing firms who bombard mobile phone users.

A BBC correspondent in Delhi says all the earlier attempts to deal with unwanted commercial messages and calls have been unsuccessful.

Subscribers can currently register their numbers with a "national do not call" list by sending a message to 1909.

In December, India announced plans to impose heavier fines on tele-marketing firms who called or sent text messages to those registered on a "national do not call" list.

The Telecom Regulatory Authority of India (Trai) also barred commercial calls or messages between 9pm and 9am.

But the messages continue to be received late at night, sometimes even at 3am, our correspondent adds.

Many people have complained that they feel harassed by calls and text messages from tele-marketers trying to sell everything from credit cards to real estate to "slim sauna belts for weight loss".

Trai officials say the number of unsolicited commercial calls have come down drastically since the "do not call" registry was launched in 2007, but the number of text messages went up exponentially.

The daily cap of 100 messages per phone is expected to deal with the problem, they say.

India has the fastest growing mobile phone market in the world, with more than 700 million subscribers.

Virtual monkeys write Shakespeare

A few million virtual monkeys are close to re-creating the complete works of Shakespeare by randomly mashing keys on virtual typewriters.

A running total of how well they are doing shows that the re-creation is 99.990% complete.

The first single work to be completed was the poem A Lover's Complaint.

Set up by programmer Jesse Anderson the project co-ordinates the virtual monkeys sitting on Amazon's EC2 cloud computing system via a home PC.

Mr Anderson said he started the project as a way to get to know the Hadoop programming tool better and to put Amazon's web services to the test.

It is also a practical test of the thought experiment that wonders whether an infinite number of monkeys pounding on an infinite number of typewriters would be able to produce Shakespeare's works by accident.

Mr Anderson's virtual monkeys are small computer programs uploaded to Amazon servers. These coded apes regularly pump out random sequences of text.

Each sequence is nine characters long and each is checked to see if that string of characters appears anywhere in the works of Shakespeare. If not, it is discarded. If it does match then progress has been made towards re-creating the works of the Bard.

To get a sense of the scale of the project, there are about 5.5 trillion different combinations of any nine characters from the English alphabet.

Mr Anderson's monkeys are generating random nine-character strings to try to produce all these strings and thereby find those that appear in Shakespeare's works.

Mr Anderson kicked off the project on 21 August using Amazon's cloud computers. Each day of virtual monkey keyboard mashing processing cost $19.20 (�12.40).

The project has been moved to a home PC to speed up text string generation and to cut the cost. To make the task even easier the text being sampled has had all the spaces and punctuation removed.

Mathematicians said the constraints Mr Anderson introduced to the project mean he will complete it in a reasonable amount of time.

"If he's running an evolutionary approach, holding on to successful guesses, then he'll get there," said Tim Harford, popular science writer and presenter of the BBC's radio show about numbers More or Less.

And without those constraints?

"Not a chance," said Dr Ian Stewart, emeritus professor of mathematics at the University of Warwick.

His calculations suggest it would take far, far longer than the age of the Universe for monkeys to completely randomly produce a flawless copy of the 3,695,990 or so characters in the works.

"Along the way there would be untold numbers of attempts with one character wrong; even more with two wrong, and so on." he said. "Almost all other books, being shorter, would appear (countless times) before Shakespeare did."

Earlier experiments have shown how difficult the task is. Wikipedia mentions a 2003 project that used computer programs to simulate a lot of monkeys randomly typing.

After the equivalent of billions and billions and billions of monkey years the simulated apes had only produced part of a line from Henry IV, Part 2.

Also in 2003, Paignton Zoo carried out a practical test by putting a keyboard connected to a PC into the cage of six crested macaques. After a month the monkeys had produced five pages of the letter "S" and had broken the keyboard.

Warning about cost of rogue apps

The premium rate regulator has uncovered two cases of smartphone apps charging users without their knowledge or consent.

Now the regulator, Phonepayplus, has issued plans for more protection for consumers from rogue traders in the industry.

In one case an app automatically sent and received text messages that could cost the user �4.50 each.

It was shut down by the regulator.

Now Phonepayplus has started consultation on proposals that consumers' consent to charge is clearer, password requirements are strengthened to prevent children buying items, and there is more explanation of the cost of virtual credit.

"We need to be nimble and flexible in our approach. We know that the best regulation is one that works collaboratively with industry to pre-empt problems that harm consumers and damage markets," said Paul Whiteing, Phonepayplus chief executive.

"We will not hesitate to use our robust sanctioning powers to drive out rogue providers who could damage a vital part of the UK's growing and innovative digital and creative economies."

Via sues Apple in US over chips

Taiwanese chip designer Via is suing Apple claiming the US firm has infringed patents it owns.

Via said the disputed ideas were used in Apple TV, the iPod, iPad and iPhone and the software they run on.

The patents involve the ways chips in these products use, transfer and manipulate data.

Via has filed a complaint with both an American district court and the US International Trade Commission.

The company's boss Wen-Chi Chen said the firm was "determined to protect our interests and the interests of our stockholders" in a statement about the lawsuit.

The legal action is widely believed to be connected to an ongoing dispute between Apple and Taiwanese smartphone maker HTC. Mr Chen is married to HTC's chairwoman Cher Wang, who co-founded both businesses.

Earlier rounds in the legal fight between the two saw Apple rack up a win as the HTC was found to have infringed two Apple patents. HTC has said it plans to appeal against that ruling.

HTC has filed three separate lawsuits against Apple over patents used in mobiles and tablets.

Apple has yet to issue a statement about the Via lawsuit.

The latest action is one of many patent spats in which Apple is involved. The company has taken action itself against Samsung in the US, Europe, Australia and South Korea. These have led to a ban on the sale of the Galaxy Tab 10.1 in Germany and bans on three smartphones in Holland.

In retaliation, Samsung has taken Apple to court in France and has counter-sued in the Netherlands.
