It was a good day for the WebKit browser engine yesterday when Opera Software adopted it in place of its in-house Presto. But yesterday's developments also became an opportunity for a high-profile JavaScript programmer to lodge criticisms about WebKit.

"Each release of Chrome or Safari generates excitement about new bleeding-edge features; nobody seems to worry about the stuff that's already (still!) broken," complained Dave Methvin, president of the jQuery foundation and a member of the core programming team that builds the widely used Web programming tool, in a blog post.

"jQuery Core has more lines … Read more

It might have been a smart strategic move for Opera Software to move to the WebKit browser engine and scrap its own Presto, but some think it's a step backward for the development of the Web overall.

"A switch to Webkit might benefit Opera. It's just not going to benefit the open Web," Mozilla's Robert O'Callahan said today in comments on his blog about Opera's Presto change-o. "This will strengthen the WebKit mobile monoculture and make it even harder for us to promote Web standards over 'coding to Webkit.'"

Opera Software, an independent voice in the browser market since the 1990s, will dramatically change its strategy this year by adopting the WebKit browser engine used by Safari and Chrome.

The Norwegian company announced the move today and said it will show off the first fruits of the work with a WebKit-based version of its Android browser at the Mobile World Congress show in less than two weeks. But the company will move to WebKit for its desktop browser, too.

A browser engine processes the Web page instructions written in HTML, JavaScript, and CSS then renders the results on screens. … Read more

A small Spanish startup called GeeksPhone has started selling phones that let developers get a taste of Mozilla's new Firefox OS.

GeeksPhone announced two 3G phones for the browser-based operating system, the lower-end Keon and higher-end Peak. The phones, while geared for programmers rather than mainstream customers, make Mozilla's open-source mobile OS a lot more real, since programmers will be able to develop apps as well as to debug and advance the underlying operating system.

Firefox OS is Mozilla's ambitious attempt to build an operating system that brings more openness to the walled gardens of Apple's … Read more

Mozilla's browser-based smartphone operating system has grown up a notch, winning over partners such as Sprint and ZTE and picking up the marketing-friendly name of Firefox OS.

In addition, Mozilla has announced several partners, a necessity for making a bunch of software into something people actually use: only a very small number of people have the skills and interest to install a mobile-phone OS.

Carrier Telefonica and chipmaker Qualcomm already were partners that emerged when Mozilla announced B2G at Mobile World Congress earlier this year. They'd said to expect phones by the end of 2012 then, but now … Read more

NEW ORLEANS--Mozilla may not be the first thing you think of when it comes to mobile technology, but that may change early next year. Its mobile operating system code-named Boot to Gecko is developing rapidly, but it will face challenges both technical and tech cultural.

Judging from my colleague Stephen Shankland's take on how Boot to Gecko performed at its public unveiling in February, Mozilla has definitely made progress with the phone. The build I used was installed on a Samsung Galaxy S II.

The interface appears to be a mix of traditional iOS-style app icons, and Windows Phone-style … Read more

It's been a busy year at the home of Firefox, as Mozilla went public with major developments meant to change the Web, but it's about to get much busier as it looks to make those initiatives a reality. A key step forward will be to unify its development schedules under a project named Kilimanjaro.

Oh, and it wants to have Kilimanjaro bagged by September of this year. The related bugs blocking Kilimanjaro have all been marked as "highest priority."

Damon Sicore, vice president of engineering at Mozilla, explained in a forum post that Kilimanjaro is about … Read more

UMass is not the first institution to look to the gecko and its remarkable powers of adhesion. A team from Berkeley announced a gecko-inspired nonskid surface back in 2006. "I can list maybe 20 other people" heading up similar work, says UMass researcher Al Crosby.

Most of that work, however, has focused on the hair on the bottom of the gecko's feet. Called setae, these hairs are only part of the reason why the gecko, among other species, can use adhesion to move along walls and ceilings.

"In order for something this large to use adhesion," Crosby says, "its tendons are stitched right into its skin. And so you have the tendon, which is very stiff tissue, connected to the skin and the setae. That direct connection is critical. Without that, the gecko could not use adhesion. This direct integration is what we ended up mimicking in Geckskin.… Read more

Mozilla's Marketplace has begun accepting app submissions, looking toward the ultimate goal of building a standalone operating system for the open Web.

As part of the company's Boot to Gecko project, these apps would allow for cross-device and multi-operating system integration, which means anchoring the apps to the user and not to the device or platform.

"Using HTML, CSS and JavaScript, a developer can build an app using responsive design, and that app can offer the same look and feel as a device-native app, without having to rewrite for every desired target platform," Joe Stagner, Mozilla'… Read more
