First Firefox OS phones arrive Tuesday for developers

A small Spanish company called Geeksphone will begin selling two smartphones on Tuesday that are geared for developers who want to build apps for Firefox OS -- or for that matter, to build Mozilla's open-source browser-based operating system itself.

As previewed earlier this year, Geeksphone has two models, the Keon at 110 euros including VAT ($143) and the Peak at 179 euros ($234) including VAT.

That's a notch cheaper than high-end unlocked smartphones you'll find, like the $574.99 HTC One, an Android phone that just went on sale. But the low price is part of the … Read more

It's about time: RuneScape dumps Java for HTML5

RuneScape, a popular massive online swords-and-sorcery game, is at last dumping Java and becoming a Web app.

Jagex Games Studio released the first RuneScape 3 beta yesterday, embracing HTML5 and related Web standards that offer programmers a more modern option for writing software that runs on a variety of operating systems.

About time, I say. Java had some potential years ago, and it still has its place elsewhere in the computing world. But as a way to extend a browser's abilities, it's history. If the plague of Java security vulnerabilities weren't enough to convince you otherwise, the … Read more

Intel releases Web-based app programming kit

Intel has released its first version of Web-based programming tools to help developers make mobile apps for Android and iOS.

The free software, called Intel XDK, isn't brand new. It's a rebadged version of the AppMobi software that Intel acquired in February. XDK lets people create software that uses the so-called HTML5 foundation, a collection of standards designed to advance the Web beyond static documents toward dynamic applications, then convert those apps so they can be used on mobile devices.

Intel announced the XDK release at its Intel Developer Forum show in Beijing this week. The software is … Read more

Why Mozilla had a change of heart about WebP images

Sure, technology decisions often are the result of personal predilection, political scheming, and inter-company rivalries. But cold hard data still can win the day -- and that's the main reason why Mozilla is reconsidering its earlier decision not to support Google's WebP image format.

Specifically, new data shows that Google isn't just blowing smoke when it promised that using WebP lets Web site operators save precious bytes when it's sending Web-page data to browsers. Smaller file sizes mean that browsers can show Web pages faster, that Web site operators cut bandwidth usage, and that people with … Read more

Mozilla takes a fresh look at Google's WebP image format

Mozilla is taking a new look at the WebP image format it once rejected after some large Web sites encouraged the Firefox developer to take a fresh look and after Google released a freshly upgraded version.

WebP, which derived from the VP8 video compression technology in the WebM project Google launched three years ago, is part of the search giant's effort to speed up the Web. In WebP's case, that speedup comes through use of an image compression technology Google says produces more compact files than either JPEG or PNG.

WebP can be used where both JPEG and … Read more

Mozilla wants you to get your game on -- in your browser

SAN FRANCISCO--If you could play high-end, 3D games in your browser at the same speed as on a console, would you? Here at the annual Game Developers Conference, the maker of Firefox revealed a plan to get you to do just that.

Mozilla's current holy grail is getting the mix of HTML5, JavaScript, and CSS that powers the modern Web to run apps at speeds that rival native code, the operating system-dependent languages underpinning apps on iOS, Android, Windows 8, and other proprietary systems.

The not-so-secret weapon in Mozilla's plan is something called ASM.js, said Director of Engineering Vladimir Vukicevic. "It's a dialect of JavaScript that can optimize [code] much better. It's around two times as fast," he said.… Read more

Google to fix some WebP image format shortcomings

Google is on the cusp of fixing some initial shortcomings of its WebP, an image format it hopes will speed up browsing.

A new version of libwebp, the library that software can use to display and create WebP images, adds support several features, some of which were the subject of criticism when Google announced WebP in 2010:

Metadata handling so people can see camera and exposure information stored in the file with the EXIF and XMP technologies.

ICC (International Color Consortium) color profiles for more accurate color rendering.

Animated WebP images, a new spin on a once-once obscure GIF technology … Read more

Microsoft to developers: This is the 'modern.IE' world

In case you weren't sure, Microsoft wants you to really, really understand that Internet Explorer 10 isn't just any old update to the much-maligned browser. The latest example: "modern.IE," a set of tools to help Web developers that the company announced today.

"It's still too hard to test sites across the different OSes and browsers," Ryan Gavin, Internet Explorer's general manager, said in a phone interview with CNET yesterday. "On our part, we can encourage best practices. We know we can do better here, so we're providing the tools … Read more

OpenCandy brings the bucks to desktop software

LAS VEGAS--If you want to make money off of apps, you must develop for mobile, right? Wrong, says SweetLabs' Chester Ng, who points to his company's success with its OpenCandy project to help developers earn a living.

The problem is both cultural as well as logistical, Ng said in an interview outside the Las Vegas Convention Center. Desktop software, especially on Windows, has a long history of being developed as freeware. But pitching a secondary software purchase to the user during the installation process had been poisoned, he said.

"The problem is that developers don't like the … Read more

Firefox 'porn mode' finally to match competition

Big changes to Firefox's "porn mode" -- the private-browsing feature that turns off recording cookies, history, and temporary files -- landed today in the Firefox Nightly build.

When it reaches the general public a few months from now in Firefox stable, the feature will allow you to run the private-browsing feature in a new window, without closing your regular instance of Firefox. This pulls the browser up to parity with Chrome, Internet Explorer, and Opera. Safari doesn't open private browsing into a separate window.

Firefox's project manager, Asa Dotzler, stated in the blog post announcing … Read more
