Intel Tools Driving Multi-Core Chip Development

Parallel Studio is intended to work with Microsoft Visual Studio for development of Windows applications intended to run on servers with multicore CPUs.

Intel this week said it has combined its parallel programming design tool, Composer, with an Inspector tool and an Amplifier tool to produce Intel Parallel Studio for C and C++ programmers.

Intel Parallel Studio is intended to work with Microsoft Visual Studio for development of Windows applications intended to run on servers with multicore CPUs. Four-core CPUs are currently in production, with six and eight core lines expected before the end of the year from Intel and Advanced Micro Devices.

With Intel Parallel Studio, Windows application programmers will be able to generate applications that run in parallel segments, or different processes running simultaneously, on Intel multicore chips. Each core is capable of processing two threads in Intel's latest Xeon 5500 chips, so a two-way, quad-core server (eight cores total) could process 16 threads or 16 separate parts of a single program concurrently, if it's been designed for parallel processing.

Such techniques promise to bring about a large increase in speed of execution, said James Reinders, director of the software developer products business at Intel.

"Applications are only just starting to appear that are optimized to make best use of these [multicore] systems," he said in an announcement yesterday of Parallel Studio's availability.

Parallel Composer provides C and C++ compilers, code libraries, and an extension to the Visual Studio debugger to allow it to debug parallelized applications. Composer also provides an Intel API, OpenMP, through which a program may connect to the parallel processing capabilities built into Intel chips.

Parallel Inspector provides analysis of newly written code, checking for threading and memory errors. It uses dynamic instrumentation so code may be reviewed and tested as its written, without test builds or complete system recompiles being run. The inspections are done inside Visual Studio's development environment.

Parallel Amplifier is an intuitive performance analyzer -- it doesn't need to know the details of the chip architecture. It can identify bottlenecks in threaded Windows applications and allow further tuning of the application.

Continuing to use tools "designed for single-core processor systems will not yield good results," Reinders warned.

Intel is one of the vendors working with the U.S. Air Force to convert an Air Force Space Command Project from a mainframe to a Xeon processor environment. Other vendors involved in the project include Rogue Wave and Mitre, a federally funded research center.

The Intel parallel processing toolset was announced at Intel's Swindon, United Kingdom, development lab Wednesday. It's available through Intel resellers listed on Intel's site. Parallel Studio is priced at $799. Each tool is available as a standalone product for $399.

World’s largest solar telescope

The world’s largest solar telescope, which can capture the Sun’s magnetic field better than other telescopes, is now operational.

The new 1.6-meter clear aperture solar telescope, the largest of its kind in the world, is housed at the New Jersey Institute of Technology in Newark, New Jersey, US.

“We are already seeing images offering a better understanding of the Sun,” said NJIT Distinguished Professor of Physics Philip R. Goode.

“With this instrument, we should be able to have a better understanding of dynamic storms and space weather, which can have dramatic effects on Earth,” he added.

Earlier this month, researchers achieved what is called first scientific light.

This means the telescope is operational. To achieve its full powers, at least three more years of work will be needed to bring on-line ever-more sophisticated hardware for observing the Sun.

Nevertheless, Goode and the BBSO (Big Bear Solar Observatory) research team were able to extract a few unique images and one is shown.

The photos clearly illustrate the before-and-after capabilities of the old versus new telescope.

“Our prized first image shows the Sun’s ever-present, turbulent granular field with its largest granules being about the size of Alaska,” Goode said.

“The small, bright points in the dark lanes are less than 50 miles across and are the smallest-scale magnetic structures on the Sun,” he added.

According to Goode, if one looks closely at the “after” photo, you will see a string of pearls.

“Each pearl is a cross-section of an intense, single fiber of the Sun’s magnetic field – the basic building block of the solar magnetism,” he said.

Goode added that the Sun is now in a state of prolonged magnetic inactivity, perhaps the longest such time in a century.

“The new telescope is ideal for studying the Sun as it rises from this strange state of quietude,” he said.

The new instrument has three times the aperture of the old telescope.

It represents a significant advance in high-resolution observations of the Sun, since it has the largest aperture of any solar telescope in existence, said Goode.

The new telescope will be used in joint observation campaigns with NASA satellites to optimize the scientific output of all observations of the Sun.

Soon, ‘hands-free’ video games

The ultimate computer game that banishes handheld controls and allows players’ gestures to dictate the action on screen is to be launched by Microsoft.

The Microsoft Xbox 360 uses 3-D camera technology, and is aimed at challenging the dominance of the Nintendo Wii.

Allowing users to kick a virtual football, drive a car or practise dance moves with a computer-generated partner simply by monitoring an individual’s movements, the entertainment system will become a must-have for any child or even a youngster.

The Microsoft camera, which is the first to be able to sense 3-D motion, is based on technology developed by 3DV Systems, an Israeli company recently acquired by Microsoft. It uses infrared light to detect real-life gestures and the players’ distance from the camera. This information is then converted into a related movement on screen.

A source close to the Microsoft project said: “By taking away the controls altogether the game becomes so easy to operate that even your grandmother can master it.”

The company refused to comment.

Videogames get more physical as recession bites

With the recession cutting out some family vacations, gym memberships, and personal trainers, a rash of new videogames designed to let people workout in their living room are hitting the shelves.

Electronic Arts has just released "EA Sports Active" for the Nintendo Wii which comes with a resistance band and a leg strap that lets players perform aerobic activities like virtual roller blading, jogging, or lunging.

"With today's economy, people can't always afford gym memberships and personal trainers," said Alison Sweeney, host of NBC's "Biggest Loser" reality TV series.

"EA calls this game a "trainer in a box" and it really is. The game teaches you the right way to work out."

The game has a built-in journal to track food intake and encourage an active lifestyle, including away from the Wii.

The trend of incorporating exercise into virtual entertainment will be showcased at next week's E3 Expo in Los Angeles, the largest videogame trade show in North America.

Sega has a new Wii game, "Daisy Fuentes Pilates" hosted by the former MTV personality, Namco Bandai has "Active Life: Extreme Challenge" for Wii, and Nintendo has "Wii Sports Resort."

Activision's "Tony Hawk: Ride" for Xbox 360 and PlayStation 3 adds physical play to the mix with a motion-sensor skateboard controller that translates gamers' physical moves into virtual tricks.

Exercise games have become an established genre for game publishers.

Konami Digital Entertainment introduced active games to the world with its "Dance Dance Revolution" game, which has sold over 11 million copies its 2001 launch.

Nintendo encouraged physical interaction with its Wii console and games like "Wii Sports" then took virtual exercise to another level last May with the "Wii Fit" which has sold over 14 million units worldwide, introducing gamers to yoga and mini-game workouts.

"Aside from the "Dance Dance Revolution" games, there have only been a handful of fitness games and, until the "Wii Fit" launched, none was particularly successful," said Michael Pachter, videogame analyst, Wedbush Morgan Securities.

He predicted strong sales for "EA Sports Active" and Sega's "Daisy Fuentes' Pilates."

Nintendo's Wii and "Wii Fit" have not only introduced more men to exercise but also paved a new avenue for female gamers.

"I've gotten e-mails from plenty of women who tell me that "Wii Fit" has helped them become more active, and it's clear that these women were not gamers to begin with," said Kristin Kalning.

Daisy Fuentes, the Cuban-born actress and model, said her pilates games that will be released this summer isn't exclusive to women.

"Pilates is able to equally cater to both men and women, especially for beginners. Since it was developed by a man and for a man's body, it focuses on many important aspects of men's fitness," she said.

"I'm excited for everyone to have the chance to feel what it's really like to experience the true feeling of skateboarding," said Hawk in a statement.

Facebook receives $200 mn investment from Russian firm

Social networking site Facebook has received a USD 200 million investment from Digital Sky Technologies, an internet investment group, in exchange for a 1.96 per cent stake in the company.

Digital Sky Technologies (DST), which has significant stake in Eastern European and Russian internet businesses, has picked up 1.96 per cent in Facebook, valuing the enterprise at USD 10 billion, the company said in a statement.

In addition, DST has indicated plans for an offer to buy at least USD 100 million of Facebook shares from existing shareholders to facilitate liquidity for current and former employees' vested shares in the company.

However, consistent with Facebook's practice with other recent investors, DST would not be represented on the Facebook board or hold special observer rights, the statement added.

"This investment demonstrates Facebook's ongoing success at creating a global network for people to share and connect," Facebook CEO Mark Zuckerberg said.

"A number of firms approached us, but DST stood out because of the global perspective they bring-– backed up by the impressive growth and financial achievements of their internet investments," Zuckerberg added.

DST's main assets account for over 70 per cent of all page views in Russian-speaking internet and its social networks are market leaders in more than 13 countries.

Microsoft to launch new Zune later this year

Microsoft Corp plans to launch a new version of its Zune portable media player later this year in the United States, incorporating high-definition video, touch screen technology and Wi-Fi connection.

Microsoft said on Tuesday the new Zune, its answer to Apple Inc's popular iPod digital music player, will also come with an Internet browser and a built-in HD radio receiver that offers higher-quality sound than traditional radio.

It did not give a price or a specific date except to say it was due in the fall.

The company added new features to Zune's music service last year, enabling users to download music wirelessly and buy songs they hear on the device's built-in FM radio.

Europe's fastest supercomputer unveiled in Germany

A new supercomputer with the power of 50,000 home PCs -- the fastest in Europe and the third worldwide -- was unveiled on Tuesday in Germany.

The "Jugene," capable of 1,000,000,000,000,000 calculations per second, ranks behind the "Roadrunner" and "Jaguar" computers in the United States, said Kosta Schinarakis from the Juelich research centre, where the computer is located.

Jugene will be used for a wide variety of operations, including research on fuel cells for electric cars, weather forecasting and the origins of the universe, the centre said.

The machine is no ordinary PC, requiring 295,000 processors located in 72 lockers each the size of a telephone box.

A memory device that may store data for 1 bn yrs

Scientists have come up with a new computer memory device that can store thousands of times more data than conventional silicon chips and that too for more than one billion years.

Packing more digital images, music, and other data onto silicon chips in USB drives and smart phones is like squeezing more strawberries into the same size supermarket carton.

The denser you pack, the quicker it spoils. The 10 to 100 gigabits of data per square inch on today's memory cards has an estimated life expectancy of only 10 to 30 years.

The electronics industry needs much greater data densities for tomorrow's iPods, smart phones, and other devices.

Now, Alex Zettl and colleagues have described the development of an experimental memory device consisting of an iron nanoparticle (1/50,000 the width of a human hair) enclosed in a hollow carbon nanotube.

In the presence of electricity, the nanoparticle can be shuttled back and forth with great precision.

This creates a programmable memory system that, like a silicon chip, can record digital information and play it back using conventional computer hardware.

In lab and theoretical studies, the researchers showed that the device had a storage capacity as high as 1 terabyte per square inch (a trillion bits of information) and temperature-stability in excess of one billion years.

The study is scheduled for publication in the June 10 issue of ACS'' Nano Letters, a monthly journal.

‘X-shooter’ to shed new light on gamma-ray bursts

ESO’s (European Southern Observatory’s) Very Large Telescope has been equipped with an instrument called a X-shooter, which can record the entire spectrum of a celestial object in one shot with high sensitivity, and will be particularly useful for the study of distant exploding objects called gamma-ray bursts.

“X-shooter offers a capability that is unique among astronomical instruments installed at large telescopes,” said Sandro D’Odorico, who coordinated the Europe-wide consortium of scientists and engineers that built this remarkable instrument.

“Until now, different instruments at different telescopes and multiple observations were needed to cover this kind of wavelength range, making it very difficult to compare data, which, even though from the same object, could have been taken at different times and under different sky conditions,” she added.

X-shooter collects the full spectrum from the ultraviolet (300 nm) to the near-infrared (2400 nm) in parallel, capturing up to half of all the light from an object that passes through the atmosphere and the various elements of the telescope.

“All in all, X-shooter can save us a factor of three or more in terms of precious telescope time and opens a new window of opportunity for the study of many, still poorly understood, celestial sources,” said D’Odorico.

The name of the 2.5-ton instrument was chosen to stress its capacity to capture data highly efficiently from a source whose nature and energy distribution are not known in advance of the observation.

This property is particularly crucial in the study of gamma-ray bursts, the most energetic explosions known to occur in the Universe.

Until now, a rough estimate of the distance of the target was needed, so as to know which instrument to use for a detailed study.

Thanks to X-shooter, astronomers won’t have to go through this first observing step.

This is particularly relevant for gamma-ray bursts, which fade away very quickly and where being fast is the key to understanding the nature of these elusive cosmic sources.

“I am very confident that X-shooter will discover the most distant gamma-ray bursts in the Universe, or in other words, the first objects that formed in the young Universe,” said Francois Hammer, who leads the French efforts in X-shooter.

Red Hat sues Switzerland

Red Hat has sued the Swiss Government for adopting Microsoft products without any public bidding process.

In a post on the Red Hat blog, the company outlines its appeal, together with 17 other companies, to a Swiss federal court to overturn a three-year contract issued to Microsoft by the Swiss Federal Bureau for Building and Logistics.

Red Hat claims the contract is worth £8 million a year, but was given to Microsoft without any public bidding process. The Swiss bureau reportedly argued when challenged that there was no alternative to Microsoft products.

However, the open-source company has countered this argument by pointing out that it already supplies technology to other Swiss organisations.

According to the blog, the case "raises important issues of openness in government and of a level playing field for open source and other competitors of Microsoft. Red Hat is seeking a public bidding process that allows for consideration of the technical and commercial advantages of open source software products."

Microsoft has yet to offer a statement on the case.

Windows 7 Starter gets strict specification list

Microsoft will limit Windows 7 Starter to netbooks running single-core processors with screens no larger than 10.2in, according to reports.

Microsoft will demand netbook makers restrict Windows 7 Starter edition to machines with no more than 1GB of RAM, a maximum hard drive size of 250GB, or a solid-state drive no larger than 64GB, and a single-core processor no faster than 2GHz, according to TechARP.

Alongside, the strict limit on cores, Microsoft will also stipulate that processors have a power draw of less than 15W, not including in-built graphics.

Such restrictions could prove problematic as netbooks increasingly grow closer to their laptop cousins, especially with Intel's dual-core Atoms, though the chip giant has restricted the sale of those processors to nettop makers to date.

The restrictions are similar to those imposed on netbook makers looking to utilise Windows XP. However, in that instance, Microsoft allowed the operating system to be used on 12.1in screens and didn't determine a maximum power draw.

Rumours also suggest that Microsoft is considering scrapping the three app limit on Windows 7 Starter edition. The limit would have meant that netbook users could only run three applications at a time, severely hampering the usability of the device.

With ex-Google exec, AOL seeks another fresh start

Shortly before taking over as head of AOL in April, Tim Armstrong ripped out some office doors.

The doors — made of glass and requiring a company key card to pass through — stood in AOL's New York headquarters, separating the offices of executives like former CEO Randy Falco and his No. 2, Ron Grant, from the rank and file.

The doors' departure is emblematic of a shift under way at AOL. Armstrong, 38, was recently hired away from Google Inc. and asked to give the long-suffering Internet unit of Time Warner Inc. yet another shot at salvaging its future after what seems like a lost decade.

If nothing else, Armstrong's arrival has thrilled employees who were unhappy under his predecessors, who were widely considered out of touch and out of place.

But Armstrong's more approachable style won't be enough to restore AOL's luster. AOL's legacy business, its dial-up Internet service, continues to dwindle while its newer online advertising service is not yet picking up all the slack. AOL's operations still make money, but that profit has been falling.

Armstrong's ability to find the right formula could be especially put to the test if Time Warner formally separates itself from AOL by spinning the Internet division off into a standalone business, as the company is exploring. That move would finally undo the $147 billion deal in which AOL bought Time Warner in 2001, which became one of the worst corporate combinations in history.

AOL would not make Armstrong available for comment. But current and former employees said his open management style, which he tried to show by taking out the doors, already has marked a stark change from Falco and Grant, who had snippy nicknames at AOL like "Rondy," a combination of their first names.

Falco and Grant joined AOL in late 2006 as part of a surprising management change by Time Warner that ousted AOL's then-CEO, Jonathan Miller. Falco had been president and chief operating officer at NBC Universal Television Group, while Grant came from Time Warner, where he was senior vice president of operations.

Falco was a terrific media executive but he didn't have Internet experience, and Grant was talented but had not managed large teams of people, said Ted Leonsis, an executive who retired from AOL in late 2006.

"You had two very good executives who were perhaps miscast at that time," Leonsis said.

In contrast, Armstrong is steeped in the Internet. At Google he was a senior vice president in charge of the company's North and South American advertising operations.

"For what they need going forward, I think that somebody from the Internet, with Internet credibility, was a good idea," Falco said in an interview.

Falco defended his tenure at AOL by noting that he had the tough job of cutting costs — $2 billion was slashed, with 2,500 layoffs, in his tenure — something that "never makes employees happy." He also refuted the idea that he wasn't communicative, saying he met weekly with employees in small and large groups.

Leonsis experienced the stir surrounding Armstrong's arrival firsthand. Shortly after his appointment was announced, Armstrong invited Leonsis and AOL co-founder Steve Case to join him at an all-hands meeting at AOL's former headquarters in Dulles, Va. The atmosphere at the meeting was "like a religious revival," Leonsis said.

This all may bode well for employee morale, but it doesn't mean AOL's business prospects have improved.

The dial-up Internet service was AOL's backbone when the company, then known as America Online, bought Time Warner in 2001. At its peak, in 2002, AOL had 26.7 million dial-up subscribers. Even as recently as 2006, dial-up was a $5.78 billion business for AOL.

But consumers have flocked to speedier offerings. Last year AOL's Internet access revenue was down to $1.93 billion, and now AOL counts just 6.3 million dial-up subscribers.

Meanwhile, other Internet destinations have eclipsed AOL's free Web site, too.

In hopes of staunching the defection of users to competitors like Google and Yahoo Inc., in 2004 AOL began shifting from its origins as a "walled garden" with subscriber-only content to an online destination where most of its news, music videos and other features were free, and supported by ads. AOL beefed up the freebies in 2006 by giving away AOL.com e-mail accounts and software that consumers had previously paid for.

Along with this, AOL realigned itself around three core businesses meant to bring in revenue from online advertising: Platform-A, which sells ads for AOL sites like celebrity gossip blog TMZ and for third-party sites; MediaGlow, which includes numerous Web sites and blogs such as Moviefone and Engadget; and People Networks, which houses the AIM instant messaging service and other social media properties.

The transition has been bumpy. After several strong quarters early in the shift to free content, AOL's online advertising growth slowed and then reversed.

Advertising revenue totaled $1.89 billion in 2006 and rose to $2.23 billion in 2007, but dropped to $2.10 billion in 2008. And then ad revenue fell 20 percent in the first quarter of this year.

While the economy hasn't helped, Platform-A has suffered from lots of turnover in its short life span. The unit, which was formed in 2007 and includes several online ad companies AOL has acquired over the years, had three leaders under Falco and Grant. Now Armstrong has brought in a fourth person to oversee Platform-A: Jeff Levick, a longtime colleague from Google.

Armstrong's challenge will be to figure out a better way to make money off the busy traffic AOL's Web sites gather.

AOL's various online properties averaged 106 million unique U.S. visitors each month during the first quarter, according to comScore Media Metrix. That ranked AOL fourth; Google, Yahoo and Microsoft Corp. were first, second and third.

"The fact that it has a large audience and makes money means wise leadership should be able to extract value from it," said John Buckley, who left as AOL's head of media relations shortly after former CEO Miller departed.

But AOL was the only member of this Web top four to see a year-over-year drop in traffic in the first three months of the year. It had averaged 110 million visitors in the first quarter of 2008.

And while AOL's operating income totaled $150 million in the first quarter, that was a 47 percent fall from the year-ago quarter.

Armstrong has "some serious work ahead of him," said Kevin Lee, CEO of search marketing firm Didit.

For now, Armstrong is concentrating on figuring out what, exactly, AOL's focus should be. He is spending his initial months visiting AOL's 7,000 employees around the world, scrutinizing AOL's products and garnering feedback that will be used to form a strategic plan.

AOL launched an internal survey in early May, hoping to get comments on what the company's goals should be. In an e-mail to the staff, Armstrong said AOL needed a mission that is reflected in its products.

"We have a huge advantage in this effort because we touch so many consumers each day, and they will take notice of our renewed focus and energy," he wrote.

Within a week, 1,000 people responded to the survey. If nothing else, Armstrong is finding out what happens when you take out doors.

Pope2You website puts pontiff on the social networking site Facebook

Pope Benedict has entered the world of social networking sites and smartphones with a Vatican portal that includes Facebook and iPhone applications.

The Pope2You website was launched Thursday and allows Facebook users to send virtual postcards with photos of Benedict and excerpts from his messages.

An application for iPhone and iPod Touch gives surfers video and audio news on the Pope's travels and speeches, as well as on Catholic events worldwide.

The new portal is the latest update in the Vatican's efforts to broaden the Pope's audience and reach out to young people.

Earlier this year, Benedict got his own YouTube channel, which is now also linked to the portal.

While wary of the potential pitfalls of new media, the 82-year-old Benedict has also encouraged young Catholics to use the Internet to spread the church's message.

On Wednesday he told pilgrims gathered for his weekly audience that young people should use the Internet to build a better world through bonds of friendship and solidarity, adding that the digital world can help make the Gospel known.

For Rev. Paolo Padrini, a technologically savvy Italian priest who led the Pope2You project, giving Benedict a presence on the world's largest online social network was in keeping with the church's centuries-old communications strategy.

"The walls of our churches are painted by the greatest artists of all time," Padrini said. "This means that the church has always invested in the culture of each period, using the best instruments available to communicate with people."

Padrini, 36, works in the small of village of Stazzano in northern Italy and routinely chats online with his 2,500 parishioners. He was also behind another Vatican foray on the web: iBreviary, an application that brought the book of daily prayers used by priests onto iPhones.

Padrini said the new project aimed to put the focus on the church by creating a Facebook application rather than a personal profile for Benedict like those made for stars and world political leaders, including U.S. President Barack Obama.

"The Pope is not a Hollywood star who signs autographs," Padrini told The Associated Press in a telephone interview Friday. "We don't follow a concept of leadership; the Pope has always made it clear that he is a servant of the church."

Some top clergymen do have profiles on Facebook, including Crescenzio Cardinal Sepe, the archbishop of Naples.

The Pope2You portal is run by the Vatican's Pontifical Council for Social Communications and is available in English, French, German, Italian and Spanish. It was launched ahead of the church's World Communications Day on Sunday.

Padrini didn't know if the Pope had been informed of the website, but said the initiative was consistent with the message the pontiff had prepared for World Communications Day.

Addressing the "digital generation," Benedict praises new media for helping people keep in touch and creating new friendships and communities worldwide.

But he also warns that social networking can become "obsessive," isolating individuals from real-life interaction.

"It would be sad if our desire to sustain and develop online friendships were to be at the cost of our availability to engage with our families, our neighbours and those we meet in the daily reality of our places of work, education and recreation," Benedict says in the message.

YouTube infested with hundreds of porn videos

Video-sharing website YouTube has come under attack with hundreds of pornographic videos being uploaded onto its site.

The sexually explicit videos and inappropriate material were uploaded under the names of famous teenage celebrities like Hannah Montana and Jonas Brothers.

Many of the videos uploaded first started with footage of children's videos, and then continued on to adults performing graphic sex acts.

In one video titled ''Jonas Brother Live On Stage'', a user posted a comment saying: "I'm 12 years old and what is this?"

Under other uploaded videos, online users posted comments such as: "Take the tags off, you''ll get us caught."

Another said: "Your gonna kill us all!"

The raid on the website has shown how easy it is to upload porn onto a site, which is viewed by millions of people on a daily basis.

And as the videos were being uploaded, many viewers added them to their favourites and rated them highly.

One of the users believed to have uploaded the pornographic material videos was 21-year-old Flonty from Germany.

"I did it because YouTube keeps deleting music. It was part of a 4Chan raid," the BBC quoted him as saying.

4Chan is a bulletin board focusing on Japanese manga and anime, but some of its more extreme sections have been described on online message boards as "sick" and "horrifying stuff".

"Anything and everything can, and usually does, happen here. We have our very own unique culture, and there is no group quite like us anywhere out there," he said.

Flonty was asked if he was concerned that children could freely watch such inappropriate material on YouTube.

"Children will find inappropriate material around the internet anyway," he replied.

"This kind of raid showed how easy it is to upload porn to a website that millions of people browse on a daily basis," he added.

YouTube owner Google said that it was aware and addressing the problem.

"We are aware of the slew of pornographic videos that were uploaded," Google spokesman Scott Rubin said.

"We are addressing them as we would any video that violates our community guidelines.

"In addition, any account we discover that has been set up specifically to attack YouTube will be disabled," he added.

Cell phone viruses poised to reach epidemic proportions

Unlike computer viral epidemics, no major outbreaks of mobile phone viral infection have been reported to date. Ever wondered why?

Well, Albert-Laszlo Barabasi, director of the Center for Complex Network Research at Northeastern University, says that it is because a highly fragmented market share has effectively hindered outbreaks thus far.

He warns that cell phone viruses will pose a serious threat once a single mobile operating system's market share grows sufficiently large, and that that may not be far off considering the 150 percent annual growth rate of smart phones.

"We haven't had a problem so far because only phones with operating systems, so-called ''smart phones'', are susceptible to viral infection," said Marta Gonzalez, one of the authors of a study report published in the journal Science.

"Once a single operating system becomes common, we could potentially see outbreaks of epidemic proportion because a mobile phone virus can spread by two mechanisms: a Bluetooth virus can infect all Bluetooth-activated phones in a 10-30 meter radius, while Multimedia Messaging System (MMS) virus, like many computer viruses, spreads using the address book of the device. Not surprisingly, hybrid viruses, which can infect via both routes, pose the most significant danger," Gonzalez added.

The experts reckon that Bluetooth viruses eventually start infecting all susceptible handsets.

Given that human behavioural patterns have been restricting the spread of such infections thus far, the experts believe that there should be sufficient time to deploy countermeasures like antiviral software to prevent major Bluetooth outbreaks.

Although human behavioural patterns do not restrict the spread of MMS viruses, they are still constrained because the number of susceptible devices is currently much smaller.

The experts say that the unprecedented challenges will surface once people become increasingly connected.

They think that studies categorized as computational social science are necessary to understand group behaviour and organization, assess potential threats, and develop solutions to the issues faced by our ever-changing society.

Acer Android phone coming 2009

Acer has confirmed that it will launch a smartphone running on the Android operating system this year.

Acer, the world's third largest PC maker, says it plans to sell around 10 new smartphone models this year, with nine of them running Windows Mobile 6.5.

Acer only entered the smartphone market in 2008, following the acquisition of Taiwan's portable device-maker Eten Information Systems.

Acer aims to take 6% to 7% of the smartphone market by 2012-2013, boosted by volume growth of cheap smartphones.

Gartner says it expects the smartphone market to surge 27% in 2009, even as the overall phone market shrinks. Acer says it's likely more PC makers, such as Dell, will look to move into the smartphone market as PC sales plummet.

"For a handset maker to move into the PC business, I'd say it was almost impossible," says the head of Acer's phone unit. "One way is acquisition, another way is, if you're willing, to invest massively and lose a lot of money for a long time."

"If you do not have large volume then you're at such a handicap it's very hard to compensate."

Mozilla straps on Jetpack

Mozilla Labs has begun demonstrating a new API that could drastically simplify the way add-ons are created for Firefox.

Dubbed Jetpack, the API allows developers to create adds-ons using web technologies including HTML, CSS and JavaScript.

According to Mozilla, the big advantage of add-ons created in Jetpack is that they won't break every time the browser gets a major overhaul - at a stroke removing one of Firefox's biggest annoyances.

Jetpack features can also be installed, toggled off and on, and debugged without needing to restart the browser. The switch to web technologies also means that add-ons can easily be ported to other Mozilla projects, such as Thunderbird, Songbird and its mobile browser, Fennec.

There's no doubt that the 12,000+ add-ons are one of the biggest draws of Firefox and by turning to web technologies, Mozila's hoping to entice more developers to create add-ons.

"We want to grow our community of developers by orders of magnitude through making add-on creation much more accessible, and yet more powerful by developing it as an extensible platform for innovation itself. Many useful Jetpack Feature's can be written in under a dozen lines of code," says Mozilla developer Aza Raskin on the company blog.

"Jetpack will be an exploration in using web technologies to enhance the browser with the goal of allowing anyone who can build a website to participate in making the web a better place to work, communicate and play."

There's already a few sample add-ons created in Jetpack to play with, including a simple ad blocker program and Gmail notification extension.

A new type of disc that stores 10,000 times more data than current DVDs

A new type of disc that stores 10,000 times more data than current DVDs has been unveiled by Australia researchers.

The revolutionary disc could be on the market within a decade, researchers reported in the journal Nature.

The discs store 1.6 terabytes of data, pipping the capacity of current DVD and Blu-ray discs which hold up to 50 gigabytes.

A standard DVD recorder uses light of a single wavelength to ''burn'' data onto the surface of the disc, reports ABC Online.

Researchers from Swinburne University of Technology in Melbourne found that by adding gold nanorods to the disc they were able to increase its capacity.

The nanorods react to light according to their shape – thus allowing researchers to record information using light of different wavelengths, or colours, on the same location on the disc.

The researchers also used polarisation, the angle of the light''s electric field, to record data.

"The polarisation can be rotated 360 degrees," says paper co-author Dr James Chon.

"So for example, we were able to record at zero degree polarisation. Then on top of that, we were able to record another layer of information at 90 degrees polarisation, without them interfering with each other," he added.

Professor Min Gu, Director of the Centre for Micro-Photonics at Swinburne, who was also involved in the research, said: "We have created a new recording device that can respond to different colour and different polarisation. By using these properties we can use more of the disc."

In their paper, the researchers were able to record three layers of information, using three different wavelengths and two polarisations.

Since publication, the authors have recorded 10 layers, and they believe it is possible to record 100 layers onto a single disc.

New software makes iPhones spreadsheet-friendly

US software developer MeLLmo has released a free application that turns iPhones into powerful tools for analyzing spreadsheets and reports, enhancing the appeal of Apple mobile devices to businesses.

The application, named RoamBi, intuitively imitates the way business reports are read and then presents results in graphics adapted to iPhones touch-screen size and capabilities, said MeLLmo chief executive Santiago Becerra.

"We are leading the way in more interactive visual reports that will power people to be more productive and make the iPhone more attractive to business," Becerra said as he demonstrated RoamBi for AFP in San Francisco.

Corporations such as Kraft Foods, Oracle and Genentech have deployed iPhones on a large scale, but those companies are exceptions in a work mobile telephone market dominated by BlackBerry, a device made by Canada-based Research In Motion.

"I can't talk to a vendor today without the iPhone coming up," said Sean Ryan, a software analyst at the market research and analysis firm International Data Corporation (IDC).

"It is ever present in people's minds and applications like RoamBi could drive more enterprise usage."

Becerra said he and other MeLLmo founders were "mesmerized" by iPhone graphics capabilities and its potential as a revolutionary technology platform.

"Mobile phones have been effective at connecting people to people any time or any place, but they have not been successful at connecting people to information," Becerra said.

"Trying to consume information on mobile devices is a painful experience; it's like trying to read a spreadsheet through a straw. You have the information, but making sense of it is hard."

RoamBi mimics the way readers' eyes navigate spread sheets or data laden business reports and then summarizes information in interactive pie or bar charts or graphs.

Applications such as RoamBi promise to help iPhones make inroads in the business market, but BlackBerry is firmly entrenched with a system built to let companies protect data and manage devices, Ryan said.

Analysts say that business leaders are reluctant to adopt iPhones because there is no platform that gives managers technical support for networks of smart phones that their employees are using.

Company managers also want tools like those used on Blackberries to regulate smart phone capabilities, such as downloading Internet files, watching videos, and taking photographs.

"The BlackBerry did come into the enterprise the way the iPhone has: executives wanted a shiny new toy," Ryan said. "The iPhone is so fun and compelling that executives want to have it and get it supported on some level."

A RoamBi Publisher that converts spreadsheet data and sends it to iPhones is hosted online as a service. RoamBi is also part of an AppExchange offered by software-as-a-service star Salesforce.com.

Basic RoamBi service is free. The year-old company plans to soon offer a premium RoamBi version on a subscription basis and sell a version of the software that can be installed in company servers.

Battery that runs on air unveiled

British scientists have unveiled a revolutionary battery that runs on air. By sucking in oxygen that reacts with carbon inside, the super-cell recharges itself.

The invention will pave the way for a new generation of electric cars, inventors at Scotland’s University of St Andrews said.

The battery uses technology called stair — St Andrews Air — that lasts ten times longer than conventional ones and is also lighter and cheaper.

Mini versions could power laptops, mobile phones and iPods.

Chemistry professor Peter Bruce, who’s leading the 1.5-million pound project to develop the battery, said: “The key is to use oxygen in the air as a re-agent, rather than carry the necessary chemicals around inside the battery.

“Our results so far have far exceeded our expectations.”

Lasers to “talk” to submarines in future

Navy physicists have announced that lasers, which can create loud bangs under the sea, might someday replace sonar for sending messages to submarines.

Conventional sonar mapping uses pulses of sound, which require towed arrays of speakers and receivers.

“You have to pull (the array) with a vessel,” said Ted Jones, a plasma physicist with the US Naval Research Laboratory in Washington, DC. “It’s slow and expensive. It might take hours or even days to search a large area,” he added.

The new technique, which is a 21st-century form of Morse code, uses self-focusing laser beams to superheat BB-size quantities of water up to 70 feet (20 meters) beneath the waves.

“The result is a little piston of steam that expands at supersonic speeds, creating an underwater bang loud enough to be heard miles away,” Jones said.

The laser pings could also be used for any of the other things normally done with sonar, such as searching for underwater objects or mapping the seabed.

To conduct a search, users could disperse passive-sonar buoys, which are designed to listen but not transmit.

Then an airplane could fly overhead, beaming laser-generated pings across the search region.

“You could quickly do a sonar search over a large area,” Jones said.

In designing the new technique, the biggest challenge was getting the laser beam to focus its energy on a small enough area to generate the pop.

“One trick is to make the beam more intense at its core, so the middle section of the beam heats the water fastest,” Jones said.

That heat causes the light around the core to bend inward until the beam focuses into a tiny point.

At the same time, the laser is made up of different wavelengths of light, which travel through water at slightly different speeds.

“If you put the slowest first and fastest at the end, it will quickly build up energy at the focal point until the superheated water goes bang,” Jones said.

According to Robert J. Sawyer, a Canadian science fiction writer, one advantage of using a laser beam to communicate with submarines is that the beam would be difficult to intercept above ground.

Apple warns of electrical shocks from iPod, iPhone

Technology giant Apple has warned of possible small and quick electrical shocks from the headphones while using iPods and iPhones.

According to the company, people could experience the electrical shock when they are using headphones to listen to these devices in areas where the air is very dry.

"It's possible to receive a small and quick electrical (static) shock from your ear buds while listening to iPod or iPhone," Apple said in a statement posted on its website.

The possible static shock could be experienced in iPod, iPhone and their accessories.

"When using headphones in areas where the air is very dry, it is easy to build up static electricity and possible for your ear to receive a small electrostatic discharge from the headphones.

"Receiving a static shock from a pair of ear buds does not necessarily indicate an issue with the iPod, iPhone, or ear buds," the statement noted.

iPod is a high-end music player while iPhone is a touch screen phone with advanced features.

Apple pointed out that this condition is not limited to Apple hardware and static can potentially build up on almost any hardware and could be discharged using any brand of ear buds.

Apple said that the condition is similar to dragging one's feet across a carpet and receiving a static shock by touching a door knob. Instead of the static charge building up on one's body, the charge accumulates on the devices that the ear buds are connected to.

Likewise, the firm pointed out that instead of the static build up discharging through your finger when you touch a door knob, it discharges through the ear buds.

The technology major has also suggested ways to minimise the risks of static discharge such as avoiding the use of headphones in "extremely dry environments or touch a grounded unpainted metal objects before inserting the headphones".

Google adds automatic translation to Gmail

Google added automatic translation technology to Gmail on Tuesday, allowing users of its email service to translate messages in another language with a single mouse click.

The Mountain View, California-based Internet giant said it had integrated its Google Translate program into Gmail, allowing automatic translation of messages in several dozen languages.

"When you receive an email in a language other than your own, Gmail will help you translate it into a language you can understand," Google said in a post on the company blog.

"If all parties are using Gmail, you can have entire conversations in multiple languages with each participant reading the messages in whatever language is most comfortable for them," Google said.

Google has already made Google Translate available to provide automatic translations of entire Web pages or blogs.

Facebook barring unusual name accounts

Alicia Istanbul woke up one recent Wednesday to find herself locked out of the Facebook account she opened in 2007, one the networking site suddenly deemed fake.

The stay-at-home mom was cut off not only from her 330 friends, including many she had no other way of contacting, but also from the pages she had set up for the jewellery design business she runs from her Atlanta-area home. Although Istanbul understands why Facebook insists on having real people behind real names, she wonders why the online hangout didn't simply ask before acting.

Facebook's effort to purge its site of fake accounts, in the process knocking out some real people with unusual names, marks yet another challenge for the 5-year-old social network. As Facebook becomes a bigger part of the lives of its more than 200 million users, the Palo Alto, California-based company is finding that the huge diversity and the vast size of its audience are making it increasingly difficult to enforce rules it set when its membership was smaller and more homogenous.

Facebook spokesman Barry Schnitt acknowledged that Facebook does make mistakes on occasion, and he apologized for "any inconvenience". But he said situations like Istanbul's are very rare, and most accounts that are disabled for being fake really are.

DisplayLink arrives on Linux

The DisplayLink technology which allows users to connect multiple monitors over USB is coming to Linux.

DisplayLink uses lossless compression technology to allow people to connect additional displays to their machines, without the need for a heavy-duty graphics card.

Currently, the technology is hampered by the USB 2 standard which means there isn't enough bandwith for intensive applications such as fullscreen video, or gaming. However, the technology is ideal for people who simply want a second monitor for browsing, or keeping watch on an email client.

At the moment DisplayLink devices only work with PCs and Macs, however, the company has now released an open-source implementation of the software under the GNU Lesser General Public License.

This should enable Linux developers to create X Servers, drivers and other Linux applications that will allow their favoured distros to discover and connect with DisplayLink-enabled devices.

To encourage development of DisplayLink on Linux, the company has also signed up with Novell which will build DisplayLink drivers into future versions of SUSE Linux Enterprise.

Dell: Windows 7 is too expensive

A Dell marketing executive claims that Microsoft is hiking up the cost of Windows 7 licences, pushing the next-generation operating system out of the reach of some users.

Microsoft is yet to release official pricing details for Windows 7. But Dell's director of product management, Darrel Ward, says Microsoft is charging PC manufacturers more for Windows 7 than it did for Vista, which could have a knock-on effect for new PC sales.


"If there's one thing that may influence adoption, make things slower or cause customers to pause, it's that generally the ASPs [average selling price] of the operating systems are higher than they were for Vista and XP," he tells.



"In tough economic times, I think it's naive to believe that you can increase your prices on average and then still see a strong swell than if you held prices flat or even lowered them. I can tell you that the licensing tiers at retail are more expensive than they were for Vista."

Ward predicts some organisations will have to think twice before rolling out Windows 7, despite its many advantages over Vista. "Schools and government agencies may not be able to afford [the additional cost]," he says. "Some of the smaller businesses may not be able to enjoy the software as soon as they'd like."

The Dell man is concerned the price hikes could slow the momentum that is building behind Windows 7. "When Vista came out we didn't have the motivation to do the types of services that we're doing now. We didn't have the clear customer demand for such services," Ward says.

"We do have a visible number of customers, large and small, who are actually waiting for Windows 7 and who have already put plans in place to target the transition to Windows 7, they're asking Dell for help. That demand and this opportunity is stronger than it has been in the past."

Microsoft was unavailable for comment at the time of publication.

Karmic Koala Ubuntu makes first appearance

Canonical has released the first alpha of Karmic Koala, the operating system destined to become Ubuntu 9.10.

The alpha was introduced by Canonical in typically ebullient fashion as "the absolute latest and greatest software the Open-Source Community has to offer," though this was somewhat undermined by the developer notes which claim "Karmic is not encouraged for anyone needing a stable system or anyone who is not comfortable running into occasional, even frequent breakage."

Anybody still ready to take the plunge will find early stage changes are few, with the headline-grabbing user-nterface overhaul destined to come much later in development.

In the meantime, users can play with the latest Gnome 2.27.1 development release, which has greater support for webcams and new options for adjusting brightness, contrast, saturation, and hue. There's also a startling list of bug fixes.

Alpha 1 also bundles the Linux 2.6.30 kernel, bringing the usual host of compatibility improvements and performance tweaks. It also remerges the latest changes from the unstable Debian release.

Canonical is also touting changes to the Intel video driver architecture, which should address some of the performance problems reported in Ubuntu 9.04, released last month.

Ubuntu 9.10 will switch from the current EXA acceleration method to UXA. It's faster, though not as stable, explaining the reluctance to use it as the default. The changes should also "dramatically" speed up the suspend and resume time.

The Alpha 1 release is available in Ubuntu, Kubuntu and Xubuntu versions. The stable version of Karmic Koala is scheduled for release 29 October.

Soft and tough fibres closely resembling biological tissue created

A group of Australian and Korean researchers have successfully used a robust network of DNA strands and carbon nanotubes to create supersoft sponge-like material whose mechanical properties closely resemble those of biological soft tissues.

Lead researchers Geoffrey M Spinks and Seon Jeong Kim consider their team’s work to be a significant advance because it takes scientists a step closer to synthetically making implant materials that will closely emulate their natural counterparts—such as tendons, muscles, arteries, and skin or other organs.

Because many biological tissues are regularly subjected to intense mechanical loads, it is also important that the implant material have comparable elasticity in order to avoid inflammation. At the same time, the material must be very strong and resilient, or it may give out.

The researchers say that the materials they have made are as elastic as the softest natural tissues, while simultaneously derive great strength from the robust DNA links used for their creation.

They further reveal that an additional advantage is the electrical conductivity of the new material, which can thus also be used in electrodes for mechanical actuators, energy storage, and sensors.

A research paper describing this work has been published in the journal Angewandte Chemie.

Hackers target 200 mn Facebook users

Nearly 200 million users of popular social networking site Facebook were targeted by hackers, with internet fraudsters stealing the passwords of many members, says a media report.

"Facebook's 200 million users have been targeted by hackers in the latest 'phishing' scam to hit the social networking website,".

Quoting a Facebook spokesman, the report said that internet fraudsters stole the passwords of a number of members on Thursday in a successful attack.

"These brought up fake Facebook log-on pages which requested the visitors re-enter their user names and passwords. Anyone who did so effectively handed the conmen the keys to their profile," the daily noted in a report published online today.

However, it is not clear how many accounts have been compromised.

Attributing to Facebook, the report said the social networking site was working to block those taken over by the hackers and minimise the fallout.

"All references to the fake domains – which include www.151.im, www.121.im and www.123.im – have been deleted from the website," it added.

According to the daily, Facebook's security team believes the hackers intended to wait until they had garnered a large number of details before taking over the accounts to spam other members with adverts for fake pharmaceuticals and other products.

The report said social networks are particularly vulnerable to phishing attacks – which can also be used to steal users' identities. This is because members tend to be less suspicious of messages apparently sent by their friends than they are of unsolicited emails, it added.

Samsung unveils Mini Notebook and Notebook range

South Korean consumer electronics major Samsung on Thursday expanded its portfolio in the notebook segment by introducing four new models under its existing N and advanced R series.

"The very positive acceptance (of the mobile PC segment) has encouraged us to further enhance our Mini Notebook offerings. We are looking at Mini Notebook segment as clear growth driver for our mobile computing business going forward," Samsung India Electronics Director-IT Business Ranjit Yadav.

The mini notebook range has four variants -- N110, NC20, N120 and N310. "The new range of mini notebooks and notebooks comes with features like LED backlit displays for brighter pictures and lower power consumption and powered USB, Samsung utility softwares, spill-proof keyboard, SRS surround sound solutions in select models," Yadav said.

"Seventy five per cent of the components going into notebooks are being manufactured in-house by Samsung," he said.

N310 Mini Notebook is one of the lightest in its class, small enough to carry in a handbag. "We expect Mini Notebooks to constitute 40-45 percent of our total Notebook sales this year," Yadav said.

Meet the robot that asks directions

German roboticists have made a mobile robot that rolls up to any humans nearby, and asks for directions to reach its destination.

The breakthrough from the Technical University of Munich is the first time that such a robot has been designed that can be properly let loose in the real world, such as city roads.

Martin Buss, who led the team behind this advance, revealed that they dumped the robot called Autonomous City Explorer (ACE) outside the university, and instructed it to find its way to the Marienplatz in the centre of Munich, some 1.5 kilometres away.

He further revealed that the robot lacked an inbuilt map of Munich or a GPS system, and just like a lost human in a similar situation, all it could do was ask for directions.

ACE uses cameras and software to detect humans nearby, based on their motion and upright posture. A speaker working in sync with the animated mouth is used to get the person's attention, and to ask them to touch the screen if they want to help.

Willing guides are then asked to point the robot in the correct direction, with the response being analysed by posture recognition software.

Once the direction is set, the robot says "thank you" before trundling off.

Pointing, rather than telling the robot where to go, avoids confusion caused by the fact that the robot and the facing pedestrian each have a different sense of left and right.

Buss revealed that during the experiment, though ACE interacted with 38 people over a period of nearly five hours, it eventually reached its destination.

Only once was ACE given the wrong directions, and it had to finally stop due to obstacles. Afterwards, it asked someone else for help, who put it back on course.

"In theory the robot has to continue on its incorrect path until it needs new information, this is why we are currently working on a system to check the information from humans for plausibility," Andrea Bauer as saying.

Impressed with the study, Paul Newman, a roboticist at the University of Oxford in the UK, said: "It's absolutely the way to go."

He says that navigating a changing environment can be a complicated cognitive task, and "invoking humans when appropriate" could be a relatively simple way for robots to meet the challenge.

A report describing ACE has been published in the International journal of Social Robotics.

Facebook tops 10 most popular online brands poll in UK

A survey on the most popular online brands in the UK has revealed that Facebook tops that chart, accounting for 13 per cent of all UK internet time last month.

As per Nielsen Online, which tracked the top 10 most popular online brands, this equated to the UK users spending one in every eight minutes on the site.

The amount of UK time spent on Facebook increased by 3.8 billion minutes in April 2009 if compared with April 2008, when UK users spent 2.4 billion minutes on Facebook.

Second on the list came Windows Live, the new name for Hotmail, which includes Microsoft's email and instant messaging tools, with users spending 4.5 billion minutes on the site, accounting for a 9.2 percent share of the total time spent on the internet by UK users in April.

Google came in third, with users spending 2.6 billion minutes on the search site, occupying 5.3 percent share of total Internet time.

The top 10 web brands accounted for 45 percent of the total UK Internet time. Consequently the other 7,625 brands tracked by Nielsen Online, have to fight for the remaining 55 per cent of time Britons spend online.

"The Internet is a complex and varied ecosystem and I think most people would be surprised by just how much time is accounted for by a relatively few brands who, in turn, are increasing their share of the pie," the Telegraph quoted a Nielsen Online spokesperson as saying.

In April 2009, the average Briton spent 22 hours 20 minutes online or using internet-related applications.

This represents a 34 percent increase on a year ago when the figure was 16 hours 36 minutes.

New electric bike adds style and speed to virtue

Most motorcyclists are happy enough to go green, except when it comes to the bikes they ride.

Pollution-free electric scooters and bicycles have been available for a while but nothing on the market so far has come close to providing what bikers would regard as a ride with the style and performance they crave.

The Zero, an electric motorcycle from California with enough speed to embarrass other vehicles at the traffic lights, may be about to change that.

Neal Saiki, the founder and inventor of Zero motorcycles, has produced the Zero S, an electric street bike with sharp styling and even sharper acceleration.

"People have waited decades for these things to be practical," he told as he launched the new bike in Europe, where he hopes to make half his sales.

"We make every part of the bike. It's very light, half the weight of a normal motorcycle."

A quick spin round the streets of east London's Isle of Dogs confirmed what Saiki meant.

The bike is quick, nimble and easy to ride. With its frame constructed of aircraft-grade aluminium and other high quality components, it's also an attractive-looking machine.

"We've had people put their motorcycles in their living rooms," Saiki said.

If most electric vehicles are the motoring equivalent of muesli, this bike is more like a martini.

It runs almost silently, which can be a little alarming. I came up behind a small group of people on bicycles, who had no idea I was there until I sped past them.

One of the Zero's limitations is its range. It will do between 40 and 60 miles on a single electric charge.

This of course cuts out long trips, although most owners will probably stay in town, where it excels, and keep topping the battery up regularly so they are not embarrassed by having to push the bike to the nearest electrical outlet.

When the bike is plugged into the mains, charging it up equates to about one penny a mile in running costs, which is certainly cheaper than fuelling up a petrol-driven bike.

Sadly, what is not cheaper is the price. The Zero S costs 9,000 pounds ($13,500), or about twice what its petrol-powered equivalent might cost.
