Using stand-alone reset timers in mobiles

Many of the most popular mobile devices have made the transition from being a predominately hardware based 'gadget' which provides a set of pre-defined tasks to an open ended platform for customizable software applications.
The transition has allowed mobile devices to act much more like PCs, offering end users a customizable feature set. In transitioning from a closed solution, where the hardware and software and all of the various device features are tied together, tested and verified by the manufacturer, to an open platform that must support any combination of third party software 'apps,' the likelihood of devices 'hanging' is much greater.

To support this flexibility, the system hardware also has become more complicated, with dedicated processors for multimedia, communications and power management, where each of these processors must also inter-operate flawlessly. In a new twist on an existing phrase used to describe PCs, the mobile device world has begun to refer to device lock-up as the 'white screen of death' (WSOD). In most cases the end user must resort to removing the battery to force a system reboot to resume device operation. Mobile device manufacturers are well aware of the inconvenience this causes their users and have asked their chip suppliers to provide solutions.

iPhone alarms hit by New Year glitch

A glitch on Apple's iPhone has stopped its built-in alarm clock going off, leaving many people oversleeping on the first two days of the New Year.

Angry bloggers and tweeters complained that they had been late for work, and were risking missing planes and trains.

Apple has acknowledged the problem and says it will be fixed by 3 January.

The reason has not been given but the glitch appears to affect single alarm settings on the Iphone 4 and earlier models with software updates.

A similar problem hit the iPhone alarm when the clocks went back in November, again causing many users to be late for work or for transport arrangements.

"We're aware of an issue related to non-repeating alarms set for January 1 or 2," Apple spokeswoman Natalie Harrison said in a statement quoted by Macworld.

"Customers can set recurring alarms for those dates and all alarms will work properly beginning January 3."

More than 1.7m people around the world had bought iPhone 4 handsets by June 2010, in what was the company's most successful product launch.

Google TV faces hurdles

Google's foray into Internet television is not going quite as planned.

Google plans to rework the software for Google TV before more manufacturers bring devices to market with that programming installed, reported US media recently. That's after critics savaged the first take of the system.

Google TV is designed to operate on special televisions or set-top boxes. Japanese company Sony and Swiss computer peripherals manufacturer Logitech are already using the technology.

The goal of Google TV is to meld television and the Internet. Viewers would be able to access Google's Chrome browser directly from their television. Hundreds of TV channels would similarly be accessible and searchable on TVs and online.

At the Consumer Electronics Show in Las Vegas in January, companies like Toshiba, LG and Sharp were prepared to present the first devices with the Google TV option. But Google has now asked them to hold off while it reworks the programme, reported the New York Times and Wall Street Journal.

It's not the first setback for Google TV. Media companies have not been willing to allow their content to be used by the system, since they fear it could hurt standard, ad-based broadcasting, as has already been the case with online libraries like Netflix or Hulu, which offer both movies and television series.

Changes in video games prompt optimism for 2011

Video game makers leave behind a year of slow sales in 2010, but are hopeful that a new generation of games for tablet computers, mobile phones and Web social networks will spur a return to growth in 2011.

The explosion of mobile games like "Infinity Blade" on iPhone and "Angry Birds" on Android smartphones has lured new consumers into playing games. At the same time, video game company Zynga has turned social network FaceBook into a hugely successful platform with hits like "Farmville" (55 million monthly players) and "CityVille" (44 million and counting).

"Before we were figuring out how to make social games, now we are mastering the art of making social games," said Mark Skaggs, vice president of product development at Zynga.

He said the next generation of FaceBook games will have "deeper gameplay, more polish, and be much more and better social experiences."

North American sales of video game hardware, software and accessories are expected to reach $20.9 billion for 2010 by the time all sales are totaled after the holidays. That figure is down four percent from 2009, according to Jesse Divnich, vice president of Electronic Entertainment Design and Research.

Yet, despite the economic slump that continues to impact gamers' disposable income, industry players expect 2011 to bring a wave of new revenue from items such as downloadable content, mobile games, and in-game micro-transactions.

Adding the new sources of revenue, Arvind Bhatia, senior research analyst at Sterne Agee, sees U.S. and European game sales up 5 percent for 2010 and another 5 percent for 2011.

Hotmail users report missing e-mails

Some users of Microsoft Hotmail are starting off the new year scrambling to get back e-mails of old. A chorus of frantic users has posted complaints on Microsoft's online forum that all of their messages have disappeared.

``Please help me get them back,'' wrote one user under the moniker 'Zacgore' in a post dated Saturday. ``All my kids' info and pictures are in there!''

Others complain that the majority of the e-mail in their inboxes was sent to their deleted mail folders instead. It is unclear from the posts how widespread the problem is. The free Web-based e-mail service is the world's most used with about 360 million users, according to comScore Inc.

Windows Live support technicians have said in numerous threads that the Hotmail team is aware of the problem and working on a fix.

``At this point it appears to be a limited issue, and Microsoft is working with individual users who are impacted. We apologize for any inconvenience to our customers,'' Microsoft spokeswoman Catherine Brooker said in statement Saturday. She declined to disclose what caused the glitch.

Microsoft's forum contains 476 pages of complaints about lost and deleted e-mails that date back to early November.

More repairs ordered for Discovery fuel tank

Cape Canaveral: NASA ordered additional repairs to space shuttle Discovery after more cracks were discovered in the ship's fuel tank, but the flight remains targeted for early February, officials said.

The shuttle's cargo run to the International Space Station, one of the final missions before the United States ends the 30-year-old shuttle program, has been on hold since November 5 when a hydrogen fuel leak scuttled a launch attempt. Technicians later found a 21-inch- (53-cm) long crack in the foam insulation that covers the tank, a potential debris hazard for launching.
Further investigation revealed underlying cracking in structural supports, the cause of which has not been determined.

X-rays of the backside of the tank, completed this week, showed additional cracks in three more of the aluminum lithium tank support structures, Kennedy Space Center spokesman Allard Buetel said late on Thursday.

Those cracks will be repaired while managers consider if additional modifications to the tank will be needed, work that could delay the scheduled February 3 launch to later in the month.

The shuttle fuel tanks have been a top safety issue for NASA since the 2003 Columbia accident, which killed seven astronauts. A piece of foam insulation broke off Columbia's tank during launch and smashed into the ship's wing. The damage caused the shuttle to break apart as it flew through the atmosphere for landing 16 days later. NASA redesigned the tanks after the accident and developed new in-flight inspection procedures.

NASA is ending its space shuttle program in 2011 after two or three more missions to complete the space station, a USD 100 billion project of 16 nations that has been under construction 220 miles above the planet since 1998. Russia already has taken over the job of transporting crew members to and from the outpost -- at a cost of USD 51 million a seat -- in anticipation of the shuttles' retirement.

NASA is also investing in commercial companies with the hope that private industry will be ready to provide launch services for astronauts by about 2015.

Microsoft plans new Windows operating system for mobile devices

Microsoft is working on a new Windows system for mobile devices like tablet computers, according to reports.

The system would focus on devices using energy-saving chips designed by the British company ARM. Many of ARM's chips are currently used in both the iPad and iPhone from Apple.

Now Windows will reportedly offer versions of its Windows CE and Windows Phone 7 systems that run on ARM chips. Its standard Desktop Windows system will be designed for x-86 architecture chips from Intel and AMD .

Microsoft head Steve Ballmer is expected to present the new systems in January at the Consumer Electronics Show in Las Vegas. The new systems should support chips from both ARM, Intel and AMD. Quallcomm, Texas Instruments and Samsung all produce chips with ARM designs.

Microsoft competitor Apple currently dominates the tablet computer market, selling 7.5 million of its iPads between its debut in April and the end of September. Market researcher Strategy Analytics estimates that Apple currently holds 95 per cent of the tablet computer market.

However, tablet computers running Google's Android operating system are expected to eat into that lead in the near future.

An alliance with ARM could help Microsoft catch up in the mobile devices market. Microsoft official Achim Berg has noted that, since the introduction of its smartphone software, Windows Phone 7, 1.5 million Windows mobiles have been sold, meeting expectations.

Physicists create supernova in a jar

University of Toronto and Rutgers University physicists have mimicked the explosion of a supernova in miniature.

A supernova is an exploding star. In a certain type of supernova, the detonation starts with a flame ball buried deep inside a white dwarf. The flame ball is much lighter than its surroundings, so it rises rapidly making a plume topped with an accelerating smoke ring.

"We created a smaller version of this process by triggering a special chemical reaction in a closed container that generates similar plumes and vortex rings," said Stephen Morris, a University of Toronto physics professor.

Autocatalytic chemical reactions release heat and change the composition of a solution, which can create buoyancy forces that can stir the liquid, leading to more reaction and a runaway explosive process.

"A supernova is a dramatic example of this kind of self-sustaining explosion in which gravity and buoyancy forces are important effects. We wanted to see what the liquid motion would look like in such a self-stirred chemical reaction," said Michael Rogers, who led the experiment.

"It is extremely difficult to observe the inside of a real exploding star light years away so this experiment is an important window into the complex fluid motions that accompany such an event," explained Morris.

Skype could be designated illegal in China

The popular Internet telephone service Skype could be dealt a major setback in one of the world's largest markets as the Chinese government cracks down on what it called illegal Internet telephone providers.

A Chinese government circular from the powerful Ministry of Information and Industry Technology called for a crackdown "on illegal VoIP (voice over Internet protocol) telephone services" and said it was collecting evidence for legal cases against them. It did not name any phone companies.

Skype was still available in China on Friday evening through its joint venture partner TOM Online.

Skype had not yet been contacted by Chinese government officials, a Skype spokesman said on Friday in the United States.

The timing of a ban in one of the world's fastest growing markets could dampen investor enthusiasm for Skype as it prepares a 2011 initial public offering. The Luxembourg-based company, which has about 124 million users worldwide, is expected to be valued at about USD 1 billion in the IPO.

The Chinese move appeared to be aimed at protecting three government-controlled phone carriers -- China Telecom, China Unicom and China Mobile -- that provide the bulk of China's telephone services.

The South China Morning Post quoted an unidentified ministry official on Thursday as saying VoIP services could only be provided by the big three Chinese operators.

China has been known to play hardball with foreign businesses. After a months-long stand-off over censorship, China finally gave Google approval in July to keep operating its Chinese search page.

Skype has 20 million users in Asia Pacific, or 16 percent of the company's total users as of the end of June, according to a US regulatory filing. The filing did not break out China's user numbers and a Skype spokesman in the United States said he did not know how many Chinese users it had.

No single country other than the United States represented more than 7 percent of Skype's average monthly user, according to the filing.

The latest news is another setback after Skype's global service outage last week, which cast doubts on the reliability of the service.

In 2005, Skype was blocked in parts of China as the government sought to ban phone calls made over the Internet.

Skype, partly owned by web retailer eBay Inc, has been growing in popularity among Chinese users and businesses to make cheap or free international phone calls over the Internet.

"Nearly 1 in 6 people in the world live in China, and a great many of them rely on Skype to connect with families and friends, run businesses, and call people around the world," wrote Skype's Josh Silverman in an October blog post about Chinese privacy.

The Chinese circular, dated December 10, did not say what amounted to illegal services and did not name any VoIP providers it considered to be breaking the law.

Representatives of the ministry and the ministry's office gathering information for the campaign did not answer telephone calls on Friday.

Representatives of China Telecom and China Unicom did not answer phone calls on Friday. A spokeswoman for China Mobile, reached in Beijing, referred calls to the firm's Hong Kong office. Attempts to reach the Hong Kong office were not successful.

VoIP calls allow users to make international calls for much less than commercial providers, or even for free if both parties are using VoIP. Many businesses that use VoIP services to cut down on their international telephone costs could lose access to the cheaper alternative.
