Google Chrome users rejoice, extensions support to be added soon

Browser extensions support is one of the biggest reasons Firefox has become so popular and is also the most requested feature by users of the Google Chrome browser. Thus it is not surprising the search giant would want to add support for them and in fact they have already laid out a plan for the feature.

Particularly Google claims user created extensions should solve three problems in Chrome: the addition of features that have specific or limited appeal, it would make life easier for users coming from other browsers that support extensions “they can’t live without,” and it will allow partners who want to create their own Chrome bundle to add specific features.

The company is not offering a timeline for the extension system but are making it a priority, to the point of specifically mentioning a bunch of popular Firefox extensions they would like to support: Stumble Upon, Delicious Toolbar, FlashGot, ForecastFox, the Skype extension and even AdBlock – despite of the fact Google relies heavily on advertising to generate the bulk of their revenues, they also seem to want this option to be available in their browser.

Microsoft admits NXE update breaking Xbox 360 sound

Microsoft is recovering from a bit of an embarrassment recently, as they have now admitted that a botched update for the Xbox 360 is what caused some people to completely lose audio on their systems. The update included a change to HDCP, which has been identified as the source of the problem.

Some workarounds included using analog audio temporarily, which was a workable solution for those who had devices capable of taking analog input. A more crude workaround was to pull the hard drive from the system, preventing the updated software from loading, which is certainly an unacceptable solution to a problem caused by an update to HDCP. Microsoft hasn't mentioned anything about how many users were affected only that it was a "very small number."

The Coming Wireless Revolution

Gadgets that operate over television frequencies promise to transform the wireless landscape.

If you believe some radio researchers and engineers, within the next couple of years, high-bandwidth, far-reaching wireless Internet signals will soon blanket the nation. Thanks to a decision by the Federal Communications Commission (FCC) last week, megahertz frequency bands that were previously allocated to television broadcasters will be opened to other device manufacturers. The frequency liberation means that future wireless gadgets will be able to blast tens of megabits per second of data over hundreds of kilometers. They will cover previously unreachable parts of the country with Internet signals, enable faster Web browsing on mobile devices, and even make in-car Internet and car-to-car wireless communication more realistic.

The FCC announcement essentially lets wireless take advantage of unused frequencies in between channels used by broadcast television, so-called white spaces. "The announcement that the FCC will allow white-space devices has a lot of people feeling like this is a beginning of a wireless revolution," says Anant Sahai, a professor of electrical engineering and computer science at the University of California, Berkeley.

For years, researchers have been toying with radios that are smart enough to hop from one frequency to another, leaving occupied channels undisturbed--an approach known as cognitive radio. But until the FCC made its announcement, cognitive-radio research was a purely academic pursuit. "You could do all the research you wanted on it," Sahai says, "but it was still illegal."

With the FCC decision, however, researchers and companies finally have the opportunity to turn prototypes into products, knowing that the gadgets could hit the market in the next couple of years. Companies including Motorola, Phillips, and Microsoft have all tested prototypes with mixed results and hope to have robust white-space devices soon.

Motorola is one of the first companies to have developed a white-space radio device that meets the basic requirements of the FCC. The device is smart enough to find and operate on free frequencies in its vicinity while controlling the strength of signals to keep them from interfering with those from other devices using nearby frequencies.

There are still lingering concerns over interference, however. This is one of the main reasons why white spaces have been off limits until now. Broadcast companies, which fund a huge lobby in Washington, were not keen on sharing their airwaves, and musicians were concerned that future white-space devices would interfere with performances using wireless microphones.

Motorola's radio finds occupied frequencies by accessing a database of registered television stations and wireless devices within its vicinity, which it determines by using GPS. Steve Sharkey, Motorola's policy director, notes that the device has a secondary way of finding free signals that involves just "listening" to the airwaves and scoping out free space. Sharkey believes that combining both methods will provide the best results.

Motorola's early tests show that there's still work to be done. During an FCC trial in October, Motorola's device, which is about the size of a suitcase and can currently only receive signals, was able to find some but not all of the allocated frequencies in its vicinity. "These aren't ready to go," admits Sharkey. "They are more developmental devices, and the idea of the test is to demonstrate the basic technologies and help the FCC understand all the interactions [between transmissions]."

While eventually it may be possible to shrink down a white-space radio to the size of a cell phone, Sharkey says that Motorola is more focused on bypassing wired Internet technology by providing broadband to rural areas and providing point-to-point wireless antennas.

Other companies are more reticent to talk about their white-space plans, but Jake Ward, spokesperson for the Wireless Innovation Alliance, a consortium of companies that helped convince the FCC to open up white spaces, says that these companies have a wide range of motives. For example, computer manufacturers such as Dell may want to build broadband wireless Internet cards that are faster and have more range than existing ones do. Software companies like Microsoft could be interested in building software and applications for new devices. And an Internet giant like Google may simply want to push Internet coverage to increase the number of people who see Google ads. "Each company has its own interests," Ward says, "but the underlying principle is that higher connectivity is better for everybody."

Ward describes one white-space application as "mind blowing": sending high-definition television signals from one room to another within a house. "You have a TiVo, a DVD player, a cable box, and three high-definition TVs," he says. "Using a white-space device, you could beam those signals anywhere, to any TV."

Of course, technical and policy challenges still remain. "Right now, a device capable of moving around to different frequencies at will is very expensive," notes UC Berkeley's Sahai. But he suspects that economies of scale will lead to affordable devices within the next couple of years. Additionally, he says, regulations need to be established to ensure that devices consistently avoid causing interference. Ultimately, however, Sahai sees no shortage of demand for the wireless spectrum. "If you build it better and faster and easy to deploy, then the applications will come," he says.

Firefox on Your Cell Phone

With the iPhone, Apple showed how to surf the Web on the small screen. Now, it seems, a modern version of the browser wars of the 1990s could be shaping up, with the battleground being the mobile phone. And there's a new list of contenders: Safari on the iPhone, Internet Explorer Mobile for Windows Mobile, RIM's BlackBerry Web browser, and a version of Chrome for Google's Android phones. Within the next few months, there will be a new entry: a scaled-down, sped-up version of Firefox, called Fennec.

Last week, Mozilla, the nonprofit organization behind Firefox, released an "alpha" version of Fennec, just as the desktop version of its browser reached 20 percent of the market for the first time. This early release lets programmers play with the interface, catch bugs, and write add-on features, says Jay Sullivan, vice president of mobile at Mozilla. Fennec (named for a type of small fox) is hardly consumer ready: it currently operates only on the somewhat bulky Nokia N810 Internet tablet, and there are plenty of bugs and interface challenges to iron out, says Sullivan. But by the first part of 2009, Fennec could be ready to run on consumer phones.

So far, says Sullivan, the feedback from the developers toying with Fennec has been positive. Early tests of the browser show its JavaScript performance, a measure of speed, will be competitive with the Android and mobile Safari JavaScript performance, Sullivan says.

But Mozilla still faces the challenge of distributing Fennec. Apple, Microsoft, and Google all have direct channels for distribution--operating systems for Internet-enabled phones. But Mozilla's path will require securing deals with other manufacturers and operating-system makers to ensure compatibility. While it's easy to upload software on a desktop computer, handset makers and cellular providers tightly control the software that can run on their handsets. For instance, Apple has kept other third-party Web browsers off the iPhone App Store.

Despite these challenges, Sullivan hopes that the novel look and feel of Fennec will boost its popularity. In conjunction with user-interface designers at Mozilla Labs, the Fennec team built a mobile browser so that its controls can be easily accessed but disappear when users don't need them. One of the main goals, Sullivan says, was to "give over the entire screen of the device to the Web content, removing all user-interface controls entirely." Using a touch-screen interface, a user drags her finger to the right to reveal open tabs, and to the left to reveal controls such as the back button and the address bar.

In addition, Mozilla designers have incorporated what they call the Awesome Bar--the smart address bar from the desktop version of Firefox that guesses which page a user wants when she types a letter or two, based on her bookmarks and browsing history. This feature has enhanced Fennec, says Sullivan, because typing on the browser is especially awkward. So Fennec's Awesome Bar also infers when a person is typing keywords for a Web search.

Moreover, Fennec will be able to work with a Firefox research project called Weave that allows a person to remotely access his desktop Web-browsing history, bookmarks, and other preferences. "One of my goals with Fennec is to leverage the number of Firefox users we have on the desktop," Sullivan says.

Future versions of the phone might even include a haptic interface, Sullivan says, meaning that the phone would vibrate, for example, when a user touches a button on its screen. "In the future, I think there's some stuff there to make interactions feel more natural," he adds, "to provide a sense of confirmation when you've clicked a button or when you're doing a drag-and-drop function." Voice control might be further off into the future, however. "I don't know if the technology is quite there yet," Sullivan says. "And we also need to be sensitive to licensing issues, as the most popular speech engines aren't necessarily royalty-free."

"I think Fennec has a good chance," says Jeffrey Hammond, mobile analyst at Forrester Research. "The first question you have to ask is what platforms we expect to see in the mobile space, and from a smart-phone perspective, I think it's a reasonable assumption that RIM, Windows Mobile, Symbian, iPhone OS, and Android all have a lot of momentum right now." However, Hammond suspects that Fennec could find a footing on the Symbian operating system, which powers Nokia devices.

Mozilla's Sullivan says that Fennec can't run on Android right now because the Android Marketplace, where phone software can be downloaded, only accepts programs written in Java. If Android were supportive of applications that could run directly on the operating system without needing to be written in Java, Sullivan says, "then it's interesting for us. We'll have to see which direction Google goes with that."

Hammond also believes that Fennec's performance could make it attractive for makers of mobile operating systems. The browser's combination of speed and small size could be crucial to its success, he says. "Speed is one reason why we've seen Firefox gain share in the enterprise, versus Internet Explorer," Hammond says. Because of that, he adds, "I think Fennec has a good chance of gaining share."

Sharing the Browser

Software lets workers collaborate online by clicking together.

Online collaboration often consists of little more than forwarding links or snippets from a Web page to a friend or colleague with a few comments dropped in. IBM is hoping to change this by letting people share the browser itself. This is the idea behind Blue Spruce, an experimental browser project that IBM hopes may change the way many people use the Web.

David Boloker, CTO of emerging Internet technology at IBM's software group in Boston, says that Blue Spruce is a logical progression for the browser. After spending several years researching mashups--applications built by bolting together several smaller pieces of software--Boloker and his colleagues realized that many of the same tools could be used to build a tool for collaborative Web browsing.

The browser in front of him shows the result. It features real-time video of Boloker and a colleague in one corner, a streaming video news clip in the center, and real-time stock data at the bottom. Both Boloker and his colleagues can control the page using separate cursors. And, using a special feature, any changes that they make to the page show up in a different color.

Blue Spruce is not, in fact, a completely new browser; it's just a clever way of linking together existing browsers (the current prototype works with a modified version of Apple's Safari). After logging in to the Blue Spruce server, several users can interact with Web pages and applications while the Blue Spruce software makes that server think that it's dealing with a single browser. Anything that a user does on the shared page is sent to the Blue Spruce server, which sends the change down to other participants.

"We really started focusing on asking, 'How do I take that browser container and extend it much further than has ever been done before?'" Boloker says. Instead of having to forward a Web link via e-mail or instant message, Boloker's group wanted to create a system that would let people share information online as easily as if they were sitting in front of the same desk. "We're trying to replicate face-to-face interaction," Boloker says. He adds that this goes beyond Web conferencing because it allows multiple users to interact with pages and Web applications, rather than letting just one user take control.

IBM hopes that Blue Spruce can prove useful for many business workers. For example, financial analysts might start the morning by navigating to a shared Blue Spruce Web page, where they analyze news stories and changes in the stock market together. If the users don't want to share an entire Web page, the project also has a "huddle" mode that lets them create shared work spaces that contain only limited information.

Although Blue Spruce currently works with only one browser, it is built with broader compatibility in mind. It uses the Web markup language HTML 5, which enables its real-time video and audio feeds without additional software. This is an unfinished standard, but it should eventually be adopted by other browsers. The demonstration system is also built on top of the WebKit, a rendering engine used by both Apple's Safari browser and Google's Chrome browser that includes some features of HTML 5. Until all browsers support HTML 5, Boloker says, his group will make Blue Spruce work by building add-ons.

Clay Shirky, an adjunct professor in New York University's interactive telecommunications program and author of the book Here Comes Everybody, says that the project is most significant in that it shows that IBM has identified the Web as a powerful business platform. "IBM, the great seller of Big Iron and custom software, has decided that simplicity plus ubiquity is a better strategy for them," Shirky says. By moving the work environment into the browser, he says, the company is acknowledging a fact of modern computing: people need tools that will be easy to use no matter what operating system they run or what programs they have, and the browser may be the best way to provide them.

Although Blue Spruce is still a research project, Boloker says that IBM plans to test it early next year with companies in the financial and health-care industries. Assuming all goes well, he says, IBM will expand to six test customers later in 2009.

One Account to Rule Them All

A new service combines many ways of communicating.

Thanks to the constant advance of communications technology, there are now more ways than ever to reach the people you know. But this doesn't necessarily mean that life's more convenient. Checking every account for new messages can be tedious and time consuming, and nowadays many people have multiple telephone numbers, e-mail addresses, and instant-messaging accounts--even several social-networking identities. TelCentris, a company based in San Diego, hopes to untangle this mess by providing VoxOx, a single piece of software that can be used to communicate with contacts in a wide variety of ways.

Unifying communications tools is hardly a new idea. Over the years, several popular instant-messaging clients have been developed to let users from one network chat with those from others. And as cell-phone use has grown, companies like Grand Central (now owned by Google) and Ribbit (now owned by BT) have focused on bringing together multiple phone numbers. The idea has proved especially popular in the business world, with companies such as IBM building products that combine a variety of communications tools--voice mail, IM, Web conferencing--with business applications like Lotus Notes.

VoxOx continues this trend but offers a more exhaustive list of services. It allows users to send e-mail and instant messages, send text messages, host video conferences, make phone calls, post messages to social networks, and even share files--all from the same place.

Rebecca Swensen, a research analyst with IDC, says that the product is interesting and ambitious. She cautions that "they're still working out the kinks in terms of how to make it easy to use." Swensen also questions whether consumers will be willing to put in the effort required to configure a service like this. Although ultimately, the service might make one's life a little easier, she says, it's a fairly big commitment to start using a new service, and to get all contacts loaded in and sorted out.

Michael Faught, chief financial officer with VoxOx, says that the service is, initially at least, aimed at younger users who "are confronted with this chaotic world of many kinds of communication tools." Faught sees social networks as compounding the problem and says that there's no simple, efficient solution.

A preview release of VoxOx was launched last week and can be downloaded for free for both Windows and Mac computers. After signing up for an account, a user is given a free VoxOx phone number and configures the rest of the service by providing usernames and passwords for compatible IM, e-mail, and social-networking accounts. VoxOx pulls in these contacts, allowing the user to scroll through a composite list and select whom to talk to and how. In some ways, VoxOx functions like a powerful instant-messaging application. Whether messages are sent as texts, instant messages, or e-mails, the conversation pops up onscreen like an IM. A user gets two free hours of calling time within the United States and Canada when she signs up, and has the option to pay for more minutes or earn them by watching ads.

VoxOx can afford to hand out phone numbers for free because it is owned by TelCentris, a communications company with existing infrastructure, says CEO Bryan Hertz. The center of the company's technology, Hertz adds, is a hub that includes support for a wide variety of communications protocols, which can be extended to include many more. "For every type of communications protocol that's an open standard, we either support it already or are integrating it into the platform," he says.

Hertz believes that the real power of the service is its ability to unify different mediums--for example, when a VoxOx user creates a three-way conference call, adding one person on a mobile phone and another on a VoIP call. However, the company acknowledges that there are bugs to be worked out. Some users have reported problems making and receiving calls, while others have posted requests on the company's forums for support for Linux and Facebook Chat. Hertz says that the company is now focused on responding to this feedback and plans to introduce more features and support soon. The company also plans to launch a version of the application for business users in early 2009.

Expanding the Mobile Web

An announcement by Adobe and ARM will let phones see more of the Web.

While it's true that more and more phones can surf the Web, it's also true that many mobile phones have only a limited ability to show much of the Web's best content. Videos that run in Adobe Flash Players, such as those by the New York Times, CNN, and Technology Review, and Flash-heavy websites simply don't work on many phones due to the software being incompatible with hardware. Today, in an effort to bring more of the Web to mobile devices, Adobe and microchip maker ARM, which powers 90 percent of mobile phones worldwide, have announced a collaboration to ensure that Adobe's software runs well on future ARM devices.

Specifically, the companies say that Adobe's Flash Player 10 and AIR (a platform for building complex Web applications) will be compatible and optimized for the ARM chips available in 2009. While ARM is used in a huge number of mobile phones, the announcement has broader implications: the chips are also used in set-top boxes, mobile Internet devices, personal media players, and automotive platforms.

The experience of publishing and viewing content on a PC is "near frictionless," says Anup Murarka, director of technical marketing of mobile devices at Adobe. "But when we get into devices like set-top boxes and phones, you run into a lot of roadblocks." While Murarka doesn't think all of the roadblocks will vanish immediately, he believes that the Adobe and ARM collaboration can help make it easier for people to post videos from their PCs or mobiles and access them anywhere.

To be sure, the agreement won't improve the Web on all devices. One big exception is Apple's iPhone. Steve Jobs has historically eschewed Adobe's Flash for the iPhone because the existing mobile version of Adobe's player, called Flash Lite, runs too slowly on the gadget. But for a vast majority of phones, the collaboration could make a difference to users. Murarka explains that the two companies worked together to optimize the software and hardware in three different ways.

First, the compiler used in Flash Player 10, which converts program code into microchip instructions, has been written to work smoothly with the ARMv6 and ARMv7 chip. This means that the software understands how these chips transport data and can tap into the right part of the chips at the right time, speeding up applications.

A second improvement, says Murarka, is that some ARM chips have been built with graphics subprocessors--pieces of silicon that are specifically designed to handle the heavy lifting of graphics rendering. Desktop versions of Flash, he says, don't use graphics processors, but the new version of Flash will take advantage of the graphics subprocessor, making graphics rendering more efficient on mobile devices and also saving battery power.

Third, the software that Adobe uses to compress and decompress videos will be optimized to run on ARM's chips. Today, content providers have to make sure that Flash videos are encoded in a specific way, in order to run on some mobile devices. This is how YouTube videos can play on the iPhone. "Flash now delivers over 80 percent of Web video," Murarka says. "By working with ARM, we can optimize that so that content that exists in video or audio form will be compatible with more devices."

A broader implication of this initiative is that both the hardware and software companies are providing the tools that programmers need to build content that works across devices, says Michael Gartenberg, vice president of mobile strategy at Jupitermedia, a research firm based in Connecticut. "The problem is [that] developers face a fragmented [mobile] landscape," he says. "And Adobe, by trying to get this content architecture on multiple handsets, is trying to make it easier for developers."

Earlier this year, Adobe announced the Open Screen Project, a collaboration with Nokia, Sony Ericsson, Qualcomm, and others aimed at standardizing Flash on mobile devices. The project led to Adobe removing licensing fees, which lets developers integrate Adobe Flash Player and Adobe AIR into any device or application without paying a fee. Many industry watchers saw the move as a reaction to Microsoft's release of Silverlight, a Flash competitor.

The announced Adobe and ARM partnership is "about the ability to get Open Screen Project onto handsets," says Gartenberg. "You've got the ARM folks supporting the technology, which is the critical first step."
