Google is on the verge of launching a Web site to showcase its extensions to customize what its browser can do.

The company's latest developer preview edition, Chrome 4.0.249.0, promotes the feature on its opening screen and its new-tab page. "New! Google Chrome now has extensions and bookmark sync," the page reads, offering a link to a site that's not public yet, https://chrome.google.com/extensions. (Bookmark sync is already available.)

Extensions and support for Mac OS X and Linux are the headline features of Chrome 4.0. It's available as a beta for Windows, with Mac OS X and Linux beta availability expected in early December. According to the Chromium development calendar, the beta is planned for December 8 release and the stable release of Chrome 4.0 is due January 12.

A number of third-party galleries for Chrome extensions already are available, but programmers for the project have said on mailing lists that a Google site is planned. Earlier this year, Google shipped a version of Chrome that pointed to a collection of visual themes before the Chrome themes gallery was actually live to the public.

Extensions are a key asset of one Chrome competitor, Mozilla's Firefox; extensions permit people to customize the browser and add new features without burdening the overall project. Firefox is getting a new extensions framework, Jetpack, starting with version 3.7 due in the first half of 2010, and Mozilla has just launched its own Jetpack gallery.

Google plans to release a Mac beta of Chrome in early December, judging by some chatter on a mailing list for the browser.

Chrome 4.0 is available today as a beta version for Windows but only as a rougher developer-preview version on Linux and Mac OS X. The standout feature of the new version is customization through extensions, a technology that long has been a core asset of another open-source browser, Firefox.

Google has been moving to a new extensions presentation technology called Browser Actions that let people interact with extensions through a small button toward the upper right of the browser window. "We've noticed that many of you have updated your extensions to take advantage of the new UI. We'd like to encourage the rest of you to do so as well," said Nick Baum, a Google Chrome product manager, in a mailing list posting.

But here's the hitch: Browser Actions only work on Windows and Linux right now. That means those building extensions will leave Mac Chrome users behind for a time. But in telling those developers they won't have long to wait, Baum mentioned the deadline for the beta version.

"The earlier you switch, the more time you will have to polish your experience for our Beta launch in early December," he said.

And Google is on the case for adding Browser Actions to the Mac version of Chrome.

"We realize this means dropping Mac support for a couple of weeks, but we already have people working on that," Baum said. "If you prioritize the Windows and Linux versions, we'll bring you cross-platform parity as soon as we can!"

It's been said that information technology is a fashion industry--that we just keep following the latest hype and fads. Oracle CEO Larry Ellison last year referred to cloud computing this way.

Ellison loves this dig, and he uses it least once every technology generation. He's not alone. I, however, disagree with the entire curmudgeon corps' "It's just hype!" attitude.

While it's true that we in IT have our fashions, just like any field of human endeavor, we're generally pretty practical. It's hard to see either IT's executives or its technicians as highly subject to the whims of style or flights of fancy. The truth is closer to the notion that we're an evolving industry--one constantly struggling to find better ways.

It's not easy to grapple with the fantastic, relentless progress afforded by Moore's Law (on the supply side), nor the constant demand for more capacity, capability, and integration (on the demand side).

In a few short decades, IT has undergone a massive shift from an engineering-oriented support role to driving the beating heart of the global economy. IT is now central to large swaths of all human activity.

As new technologies and strategies come online--whether network computing, open source, agile development, service-oriented architecture (SOA), cloud computing, virtualization, or whatever--we seek to employ them to improve our outcomes.

There's always a bit of experimentation and a bit of hype involved in the early days. Indeed, without that willingness to "try it out" and a strong shot of enthusiasm on the side, we wouldn't be advancing as well as we are. That's not just hype you're hearing; it's also the will to progress. And for the most part, the recipe works.

Most of the major new approaches touted over the past few decades have become workaday parts of the IT landscape. Most apps, for example, are now "client-server" in design. Linux and other open-source engines run much of the Internet. SOA is how enterprise IT is designed.

The same Web services that Ellison derided years ago now underpin much of e-commerce, as well as high-interactivity Web 2.0 services such as Google Maps. And virtualization and orchestration--frequently discounted at the top of this decade--are now fundamentally changing how data centers are operated.

Indeed, when one of these previously experimental, previously hyped approaches recede from view, it's usually not because they've failed but because they've succeeded so well that we don't need to talk about them anymore. They've been burned into the way we do IT.

Each wave of technology builds on the last, incorporating its best parts, weeding out what didn't work, and often re-emphasizing themes that had appeared years before but weren't quite workable at that time--though often using different names. The utility computing, grid, and application service providers of years past, for example, have become the software as a service (SaaS, or more generally, ITaaS) and cloud computing of today.

So when something new comes your way--a new approach, a new strategy, a new way of looking at or doing IT--by all means, be skeptical. Try it out in careful, measured ways. But do try it out--and have enthusiasm for those new things. That's how we advance.

With all the hubbub about Snow Leopard and Windows 7, there's another operating system out there you may not have noticed that's getting a significant update: Ubuntu Linux.

Ubuntu backer Canonical plans to release its "Karmic Koala" version on Thursday, and both the desktop and server versions of the open-source operating system take significant steps toward cloud computing. The concept of moving work away from the computer in front of you and into the network does have some merit, but cloud computing is today's fashionable buzzword, and Canonical Chief Executive Mark Shuttleworth is sensitive to its overuse.

"What frustrates me is the term 'cloud' has come to mean anything with an Internet connection, including some stuff that really looks familiar like internal IT," said Shuttleworth in an interview. It's fair to say that in Ubuntu's case, though, it's not a stretch.

Built into the server version of Ubuntu 9.10 is Ubuntu Enterprise Cloud, technology built atop the Eucalyptus software package. Amazon Web Services (AWS), a collection of computing infrastructure accessible over the Net on a pay-as-you-go basis, is among today's most significant cloud-computing efforts, and Eucalyptus implements many of its functions so companies can build their own "private clouds" using the same services.

And in the desktop version of Ubuntu, the cloud connection is a service called Ubuntu One, which lets Ubuntu users synchronize files stored on different machines and back them up on the central service. Storage space of 2GB is free, and 50GB costs $10 per month.

The Ubuntu software itself is free; Canonical sells Ubuntu support services.

The Opera 10 browser is now ready to download for Windows, and Mac, and Linux, three months after the beta first emerged (hands-on Opera 10 beta review).

If you've been keeping up with the beta updates, the final build of the cross-platform browser shouldn't surprise you. Opera Turbo, the browser's much-publicized compression engine for slow-poke connections, remains a feature highlight. Opera claims that Opera Turbo runs the browser up to eight times faster on suffering connections than do competing browsers.

The refreshed user interface is also noteworthy. Joining the new default skin (changed from version 9.6), are changes to tab bar behavior. The conventional tabs double as thumbnail images. Double-click the thin gray bar below the tabs (indicated by dots) or click and drag to expand open tabs into preview windows that you can navigate by clicking among them.

Other enhancements include an expanded Speed Dial (a feature that has later been adopted and adapted in Google's Chrome browser) that shows more commonly visited Web pages than in previous Opera browsers. You're also able to customize it with a background picture. You'll see that spell check will be applicable to any text field (for 51 languages), and that Opera's incorporated e-mail client takes a page from Google's books by threading e-mail conversations.

Developers get access to a newer version of Opera Dragonfly, the publisher's online development tools, but everyone can benefit from the speedier rendering engine that, according to Opera, makes version 10 up to 40 percent faster than version 9.6--before switching on Turbo's compression.

Despite all the additions that Opera hopes will keep Opera 10 competitive, there are still two notable omissions for this final release. The first is Opera Unite, which uses your browser as a Web server for sharing your content with others. The second is the Carakan JavaScript engine that promises to process JavaScript about 2.5 times as fast as the engine used in Opera 10 alpha.

Google has begun work on a 64-bit version of Chrome for Linux, a move likely to whip Linux loyalists into a lather of excitement.

"The V8 team did some amazing work this quarter building a working 64-bit port. After a handful of changes on the Chromium side, I've had Chromium Linux building on 64-bit for the last few weeks," said Chrome engineer Dean McNamee in a mailing list message Thursday.

V8 is Chrome's engine for running programs written in the JavaScript language common on the Web. Chromium is the open-source project behind Google's branded and supported Chrome browser, and McNamee shared instructions for programmers to build 64-bit Chromium.

Virtually all PCs today come with 64-bit processors from Intel or Advanced Micro Devices, but for desktop computing, 32-bit operating systems and software are common. The transition to 64-bit software is well under way--notably with Linux and Mac OS X--but the change isn't simple. In the browser world, for example, it can be problematic running a 64-bit browser with a 32-bit plug-in such as Adobe Systems' Flash, Microsoft's Silverlight, or Sun Microsystems' Java.

One of the things that has been most-surprising about the advent of Netbooks is that it has become less about the hardware as much as how mainstream operating systems and applications have had to adapt to fit within their confines. In the earlier generations of these machines, operating systems like Windows Vista just didn't cut the mustard, which is why most Netbooks you can buy right now are either running Windows XP or a variant of Linux.

While that is certain to change with the release of Windows 7 in late October, which runs leaner and meaner than Vista ever did (and could even come on a thumb drive), Microsoft's stumble opened things up for other operating systems to come in and fill the gap. Many consumers have more of a choice than ever with alternate operating systems that are becoming easier to install and use on these smaller machines.

One of those, called Jolicloud is launching in beta in the next few months. Created by Tariq Krim, who founded and later left widget-based start page Netvibes, the alternate OS has been designed for Web workers, or people who do most of their work (or play) on Web applications and services.

I've been giving it a thorough run-though over the past few days and have come away impressed at what it's trying to do. Some bits and pieces are definitely still beta, but the underlying approach of making Web sites and software applications feel the same, as well as introducing users to new ones to use is really innovative.

How it works

Jolicloud centers on a directory of applications that can be sorted by genre, release date, and popularity. To download or remove them from your computer, you just click on their icon and it does the rest. Jolicloud groups both Web apps and software programs under the same name umbrella, and both are added and removed from your system in the same manner. There's also a normal add and remove programs tool just like you get in Windows, but it's easier to do it from Jolicloud's rounded and simplistic interface.

To install or uninstall "applications" you can head to Jolicloud's online directory.

Jolicloud is designed to let users hop back and forth between apps that all use the entire screen. Apps you have open stay in a top menu bar and can be switched back and forth just by clicking on them. Alt+tab works too.

Interestingly enough, you don't actually launch any downloaded app from the directory screen. Instead... Read more

Apparently, organizing the world's information and making it universally accessible and useful will require a new operating system.

Google has long worked on expanding its reach beyond mere Internet search. And as many had suspected, it confirmed late Tuesday night that it plans to develop a lightweight operating system based on Linux and Web standards for personal computers.

Why? Well, Google's standard response to any question about why it's working on something other than search is to declare that any product that helps people get on the Web, and enjoy their experience on the Web, benefits Google's advertising customers in that more Web users equals more Google searches.

Yet, Chrome OS represents something more. There's a competitive impact that can't be ignored, no matter how often Google insists that it's in this world to do good rather than inflict pain on other corporations.

Few details were available Wednesday concerning one of the most important and ambitious projects Google has ever undertaken. Sources familiar with the Chrome OS project say Google engineers have only been working on the project in earnest since the beginning of the year, so there's likely a lot that still needs to be ironed out.

Chrome OS is the byproduct of Google thinking it can do better than Windows, Mac OS X, the various flavors of Linux, and even its own Android operating system. It's long been obvious that the world has changed from a personal computing model built for individuals working offline or businesspeople sharing files across a workplace to one where the consumer/business lines have blurred and people are expected to be online anywhere and everywhere.

Accompanying that shift has been the decreasing importance of processing power and operating system complexity. For years, the dirty secret of the computer industry has been that most people don't use nearly the amount of headroom provided to them by modern microprocessors and operating systems.

After all, if you're searching the Web, sending e-mail, typing up documents, touching up photos, and updating your Facebook status--hardly an uncommon usage model--you're more concerned with speed and battery life than raw power. Those still playing Doom or editing video will always need something more robust, but most people do spend an awful lot of time in the browser and have embraced smartphones and Netbooks as a way of staying online on the go.

Google's general idea seems to be twofold. First, it wants to make it easier for regular people to use a computer by making an operating system that is fast, secure, and lightweight enough to run on portable devices.

Sources familiar with Google's plans for the Chrome OS said that the company is working on a new method of "windowing," or switching between multiple applications. Google also believes that the whole idea of storing your files and applications in folders is an archaic way of organizing your data, and plans to unveil a new user interface that handles things a little differently.

Secondly, Google believes that through the use of Web standards like HTML 5--promoted heavily during its recent Google I/O conference as the development platform of the future--software development on a browser-based OS will be easily understood by developers reared in the Web 2.0 era.

This is not a new idea. Palm is betting its future on such a strategy, having introduced WebOS on the Palm Pre as a Web-friendly development environment based on a browser engine running atop Linux. Sound familiar?

Google's Chrome OS could be running on Netbooks such as these by the second half of 2010.

Google brings much more to bear than Palm, however. It has an entire suite of Web applications and services that already form much of what you want a computer to do: send e-mail, compose documents, edit photos, and, of course, browse the Web.

But why does Google think it needs two operating systems to address this evolving usage model? Much of the language used to introduce Chrome OS could have been pulled from a blog post two years ago introducing Android, Google's lightweight Linux-based open-source smartphone operating system.

Just a few months ago Google's Andy Rubin declared Android to be "a revolution" that would help Google conquer the write-once, run-anywhere goal that has eluded the non-Microsoft software community for so many years. And Google executives have endorsed the concept of other companies building things other than phones based on Android.

However, Android appears to now occupy a different role in Google's thinking. According to Tuesday night's blog post, "Android was designed from the beginning to work across a variety of devices from phones to set-top boxes to netbooks. Google Chrome OS is being created for people who spend most of their time on the web, and is being designed to power computers ranging from small netbooks to full-size desktop systems."

As noted, there are an awful lot of details that still need to surface before we can glean Google's true intent with Chrome OS, not to mention the potential impact. Google said it plans to release the code for Chrome OS later this year, with the expectation that devices based on the OS could arrive in the second half of 2010.

But one thing is for sure: Google's ambitions are boundless. The company is proposing to do nothing less than rewrite the rules that govern personal computing.

Wednesday's two big technology stories--Google's Chrome-based operating system and cyberattacks against U.S. and South Korean government Web sites are oddly related. The stories are connected because if Google does well at gaining market share for its browser, we could see fewer successful attacks. Or maybe we'll see more attacks.

The reason hackers succeeded in launching denial-of-service attacks against government computers in the U.S. and South Korea is because they were able to enlist an army of "zombie" computers to carry out the attack. And what do those computers likely have in common? The vast majority of them likely run Microsoft Windows.

Whether Windows is inherently less secure than Mac OS X or Linux is debatable, but one thing is for sure--it's more popular and therefore a more attractive target to hackers. Indeed with nearly 90 percent of the world's PCs running Windows, it's something of a "single point of failure." Figure out how to infect Windows PCs and you can stage a very successful attack.

Linux--which is the underpinning of Google Chrome--is not entirely exempt from malicious software but historically Linux machines are less likely to be infected. So it stands to reason that the more machines running non-Windows software, the safer we'll all be.

But there's another side to this story. The Chrome OS will be far more Web-centric than Windows, which means that many--if not most--of its applications will be running over the Internet. What's more, people's data will be stored "in the cloud," much of it on servers run by Google. So while Google may help reduce Microsoft's potential as a single point of failure, it increases its own. If hackers were successful in launching an attack on Google, that would affect not only people's ability to use Google apps, but the integrity of their data.

Although there weren't any reported data breaches, there was a day in May of this year when Google sites were partially inaccessible as a result of a technical glitch. On that day, millions of people were unable to use Google services, including Google Docs and Spreadsheets. Say what you want about Microsoft, but even if the company totally shut down its Web operations, its operating system and PC applications would still run.

Personally, I'm a big believer in competition and like cloud computing, so I welcome Google's entry into the operating system arena. But like almost anything worthwhile, it's not without risk.
