"The O3D team is working on getting O3D integrated into the Chromium build, and we're close to being able to complete our first step towards integration," said programmer Greg Spencer in a mailing list announcement Wednesday about Chromium, the open-source project that underlies Chrome itself. "I'll be making the Windows build of Chromium be dependent upon building O3D as part of the build process."

By helping to pave the way for high-powered Web-based games, the move furthers Google's ambition to speed the transformation of the Web from a static medium into a foundation for applications. Another piece of the work is Google Native Client, which is designed to let Web applications take advantage of a computer's native processing power.

The overall effort has taken on new importance with the announcement of Chrome OS, Google's Chrome-based operating system set to arrive on Netbooks in the second half of 2010. Chrome OS will use Linux under the covers, but the real foundation for Chrome OS applications is the Web, Google has said.

Native Client coming, too
Google plans to build Native Client into Chrome, too.

"We recognize that there is well-justified resistance to installing browser plug-ins. For this reason, we have a strong preference for delivering Native Client pre-installed or built into the browser, and we'll be focusing on that as our main strategy for delivering Native Client to users," said Brad Chen, engineering manager of the Google Native Client effort, in June.

Just offering the technologies is only a first step. Google must convince programmers to learn to use them and convince Web developers to embrace them. That's not simple, especially when few browsers can take advantage of them.

Chrome won't be the only browser to feature the acceleration features, though, because Google is working on plug-in versions, too. By building the technology into Chrome, Google could exert some pressure on others to support it.

Making Native Client and O3D into some kind of standard could help convince programmers the technologies are worth supporting and win over potential rivals. "The support of ratified standards (that Web developers) can use is something that we are extremely supportive of," said Amy Barzdukas, general manager for IE, in an earlier interview.

After years of near-dormancy, development of HTML, the language used to describe Web pages, has hit a feverish pace right now as browser makers try to make the Web into more of an applications platform.

Browser wars are back
Google added new fury to the browser wars when it introduced Chrome in September 2008. Chrome has attained a small but respectable market share of nearly 2 percent, according to research from Net Applications, but it has a long way to go expanding from the technophiles to the mainstream.

Chrome doesn't have the Internet Explorer or Safari advantage of being built into an operating system--though that could change over the years if Chrome OS manages to overcome its challenges and catch on widely. And Mozilla's Firefox took years to achieve its present market share of about 20 percent, making it the top alternative to IE and in widespread enough use that Web developers often choose to make sure their Web sites work with it.

Google has been spending a lot of time reproducing what other browsers already have--plug-ins, bookmark management, print preview, and any number of mundane but useful features. But Google also has been working on innovation, including more robust security and faster performance when running applications written in the JavaScript Web programming language.

Google has high hopes that it'll be able to match the performance of desktop applications with its technology.

"With O3D, we think we'll be able to enable high-quality games, the kind you're accustomed to seeing on consoles, as well as CAD (computer-aided design) applications," Chen said in a May speech. And regarding Native Client, "We want to be within single-digit percentages of what you can do with the best desktop native code," he said.

Google also is participating in a separate 3D Web graphics effort spearheaded by Mozilla and the Khronos Group.

Thunderbird 3 beta 3 is now available to download for Windows, Mac, and Linux users. The beta introduces some significant improvements to the open-source desktop client, from performance to interface.

The new beta is built on Mozilla's Gecko 1.9.1.1 platform, keeping it up to date with the latest changes that affect Firefox. Mozilla also claims that there are more than 500 changes in this version, and hints at more alterations to come by stating in a press release that many of them are ''laying the groundwork for future changes''. On his blog, Chief Technical Officer of Mozilla Messaging Dan Mosedale said that many of the improvements will help support the new global database search engine. Based on these comments, more betas of Thunderbird 3 are expected.

The interface and behavioral changes in this beta are significant and should be easy to spot for longtime 'bird-watchers. The biggest is that Thunderbird now supports e-mail tabs. If you've checked out the highly unstable Shredder version of Thunderbird, or Postbox, a competitor that's based on Thunderbird's own open-source code, you've known that this feature has been due for a while.

Hitting Enter or double-clicking a message will now open it in a new tab and make it your focus. Middle-click an e-mail to open it in a new tab but retain your focus on the current tab--usually the folder pane. You can switch tabs via the hot key combo CTRL+Tab, and the new tab menu button on the right side of the tab bar will help you manage your tabs.

Another new feature is the message summary view, which you can see when you select multiple messages at once. They'll open in the message preview pane. Changes to folders include a Smart Folders mode, which gives users the ability to combine inboxes from multiple accounts, and the new ability to customize column headings on a per-folder basis.

Gmail integration has existed in Thunderbird for a while, but improvements to the feature in this beta include better recognition and integration of Gmail's special folders. These include Sent and Trash, and non-English versions of Gmail. All Mail defaults in Thunderbird to the Archives folder.

The account setup wizard has been overhauled. Reachable under File, then New, Mail, and Account (Quick Setup), Thunderbird now looks to mozillamessaging.com to look for additional information on how to configure the account. Mosedale stressed in his blog that only the domain name from your e-mail address gets sent to Mozilla's servers, and that the entire process falls under the Mozilla's privacy policy. Nevertheless, it's a move that's likely to cause some concern among privacy advocates.

The compact header mode has been deleted, which is sure to annoy those who like using Thunderbird on smaller-form computers like netbooks. Mosedale cited bandwidth issues as well an ongoing need to improve the design and configurability of the feature.

In my own experiences with Thunderbird 3 beta 3 for half a day, users with large inboxes should be careful to note that Thunderbird now adds all your messages to its search archives. This can hamper performance until it's completed. Also note that the calendar extension Lightning isn't compatible with beta 3 unless you're using the nightly build.
