I've been picking on Microsoft a bit lately, so here's a pointer to something cool that it's doing: helping port Node.js to Windows. Joyent competitor Rackspace is pitching in as well.

Earlier this year at NodeConf, Node.js creator Ryan Dahl said that Windows support was a high priority for the 1.0 release. It's good to see him getting some help.

Last week Microsoft issued a blog post stating that Internet Explorer will not support WebGL because WebGL is inherently insecure. The post was based on research conducted by the firm Context, which showed that WebGL could be used for denial of service attacks or use the GPU to run malicious code. Microsoft complained that WebGL is too reliant on third parties (ie, GPU vendors) to secure the Web experience.

The only problem, according to Chrome developer Gregg Tavares (not speaking on behalf of Google), is that Silverlight 5 has the exact same vulnerability. Microsoft says it has fixed the vulnerability and the fix will appear in the next beta release.

According to a post on the Mozilla Add-Ons Blog, 85% of Firefox 4 users have at least one add-on installed. The average user has five add-ons installed. The figure doesn't include the Personas feature and excludes add-ons bundled with other software that users haven't actively chosen to install.

"We previously estimated that at least a third of Firefox users had chosen to install an add-on, but knew the number was higher than that," wrote Justin Scott, the product manager for add-ons at Mozilla.

File storage and document collaboration software-as-a-service provider Box today announced integration with Google Docs. Box users can now edit documents stored in Box using Google Docs, as well as create Google Docs files within Box folders.

Earlier this year Box announced integration with enterprise content management systems such as SharePoint and Documentum. The company is now positioning itself as a piece of glue between ECM and Google Docs.

The reviews are in. Windows Phone "Mango" is a hit with gadget bloggers. "Mango," the code-name for Microsoft's upcoming release of its mobile operating system Windows Phone, is a big leap forward with a total of around 500 new features. Many of those are addressing real pain points for current users. With Mango, Windows Phone finally gets long sought after features like multi-tasking, conversation views, voice integration, plus several unique tweaks involving Bing, better live tiles, Twitter integration, Facebook Chat and more.

But some of the updates in "Mango" are even more forward-thinking. Windows Phone is pushing users to move beyond apps for some of the core use cases involving smartphones. Meanwhile, it's introducing a new paradigm for recommending applications to the phone's end users.

A Microsoft-approved "jailbreaking" solution for Windows Phone is on its way soon, promises a recent blog post from the creators of ChevronWP7 Labs, a new site for Windows Phone enthusiasts and developers. The service will be provided by longtime Microsoft fans Rafael Rivera, Chris Walsh and Long Zheng in partnership with Microsoft, who, last year, notably decided to embrace its hacking and homebrew community, instead of outlaw it.

Big, or at least unbounded data, continues to have a profound impact on business intelligence, business analytics and data warehousing.

This week we saw a few particular developments in this area, as Endeca and SAP announced the next versions of some key products, and Microsoft CEO Steve Ballmer gave some insight into Microsoft's big data strategy.

According to a new report from Forrester, Windows 7 is now in use on 20% of corporate desktops as of March 2011. Windows XP still holds on to 59.9% of the enterprise desktop world (down from 67.5% a year go). Apple now has an 11% share of the corporate desktop (up from 9.1%). Linux has only 1.4% (it was 1.3% a year before this study).

Meanwhile, Internet Explorer use is declining slightly while Chrome and Safari are on the rise.

Last year we told you about a few plugins for Microsoft Outlook users with Gmail envy. Here's another one for that list: Priority Inbox for Outlook.

This is a third party plugin not associated with either Microsoft or Google that can organize e-mail in a way similar to Priority Inbox feature in Gmail. It costs $19.90 and is available for Outlook 2007 and 2010.

Web developers who want see how their sites will look on the new version of IE 9 Mobile, which will soon ship along with Windows Phone "Mango," the next-generation update to the Windows Phone mobile OS, now have a new tool to do so. Today, Microsoft has launched Mobile Test Drive, a companion to the Internet Explorer Test Drive site for the desktop. The new site features a number of HTML5 and performance demos highlighting IE 9 Mobile's capabilities.
