Mozilla Announces Platform-Independent App Store
A marketplace with apps for a variety of platforms. That's the vision of a new Mozilla Marketplace, announced Thursday by the non-profit maker of the Firefox browser.The apps available in the new Marketplace will not be platform-specific, as those in Apple's iTunes App Store or Google's Android Market are. Rather, it will feature apps that use open Web technologies, such as HTML5, JavaScript, CSS and Mozilla-proposed Application Programming Interfaces (APIs) for rich media apps. The organization said that users will be able to purchase an app once, and then use it on any HTML5-enabled device, across operating systems.
'Biggest Playing Field Imaginable' "We are enabling the Web to be the marketplace, giving developers the opportunity to play on the biggest playing field imaginable," said Mozilla Chief of Innovation Todd Simpson, in a statement. In Mozilla's approach, the Web itself becomes the platform.
The "write once, deploy everywhere" vision has been tried more than once before, such as with Java-coded client applications and Web-based hosted applications. Mozilla said that its approach will provide open and flexible billing options, and that the use of Web standards will "massively reduce the cost of creating, versioning and maintaining applications."
Both Apple and Google have been backers of HTML5 technologies, but have so far avoided creating a venue for apps to run on others' platforms.
The Marketplace is one component of the new Mozilla Web App platform. It will be open for developers' submissions at the Mobile World Congress in Barcelona next week, and will be accessible to consumers and businesses later this year. Categories will include games, media, music, productivity and other areas.
The other two major components are proposed APIs, and a new identity system. The APIs will be submitted to the W3C standards body for approval, and the identity system is intended to tie apps to...

In praise of ... second sleep | Editorial
Sleep cycle runs over four hours, so why do we panic at failing to forcibly bolt two cycles together into an eight-hour slumber?
You know the feeling. You stir in the dark, head buzzing first with thoughts about the day ahead, thoughts which soon yield to despair about getting through it after rest has been cut brutally short. Such anxiety may seem part of the human condition, but in fact it's a poisonous product of the relatively recent fluorescent turn taken by western societies. Everybody knows the sleep cycle runs over four hours, so why do we panic at failing to forcibly bolt two cycles together into an eight-hour slumber? Craig Koslofsky, a historian who illuminated the whole idea of the night on a recent World Service broadcast, has established that in pre-street-lit days the custom was to rise after just four hours – not for fretful wakefulness, but for prayer, talk or indeed sex – before a second sleep. "Regenerate man finds no time so fit to raise his soul to Heaven, as when he awakes at mid-night," wrote one scribe of "Mid-Night Thoughts" in 1682. Would that it still were so.

22:51A new study released by Canalys Thursday demonstrates that the world's most popular iPhone apps are being priced significantly lower in Apple's iTunes App Store than the top paid Android apps in Android Market.
In the United States, for example, the average price of Android Market's top 100 is $3.74 per Android app, vs. $1.47 per iPhone app in the iTunes App Store.
Though it is a plus for developers to apparently be able to charge more for their apps on Android, the reality is that fewer people are willing to purchase apps on Android than on iOS today, said Rachel Lashford, managing director for mobile and Asia-Pacific at Canalys.
"Developers and publishers need to balance the iOS volume opportunity with a potentially greater value per download opportunity on Android -- where more apps command higher price points," Lashford said.
Though selling more apps at higher prices is the Holy Grail for developers, achieving big volumes on Android is no small challenge, Lashford said.
"More aggressive price competition around Android apps would help to encourage more consumers to make their first app purchases, drive greater download volumes, and ultimately be good for the vibrancy of the app ecosystem," Lashford said.
A Much Bigger Audience to Monetize There are several key factors that are likely influencing the mobile app price discrepancy between Android Market and the iTunes App Store, said Al Hilwa, director of applications software development at IDC. For example, the early market leads that Apple gained when it launched its iconic iPhone and iPad should not be overlooked.
Developers price their apps "based on the volumes they anticipate to sell," Hilwa said. "The bigger the demonstrable audience to monetize over, the lower and more competitively you can set a price."
What's more, Apple has not only captured "the upper end of the user-base" but also...
