SAN FRANCISCO -- Google long has been a firm believer that JavaScript, the programming language used to build Web apps such as Google Maps and Gmail, could shoulder a much heavier computing load.

But even as the company continues to push JavaScript's abilities with Chrome's V8 engine, some at the company believe JavaScript is pushing up against its limits. For that reason, Google developed its Dart programming language, and at the Google I/O developer show here, the company made the case for Dart.

"The ultimate goal is to get Dart into Chrome. I hope you all … Read more

SAN FRANCISCO -- Google would like to endow Chrome with Microsoft's technology for letting Web applications deal with input from mice, pens, and touch screens.

Developers of the Google browser said at the company's Google I/O show here Thursday that Microsoft's Pointer Events approach -- built into IE10, Windows 8, and Windows Phone 8, and being standardized at the World Wide Web Consortium -- has some real advantages.

"We're going to start landing some experimental support in Blink for Pointer Events," said Chrome programmer Rick Byers. Blink is the open-source browser engine at … Read more

SAN FRANCISCO -- By now Street View is a routine part of online mapping. But people might not be so familiar with how Google actually gets the data for its 360-degree panoramic views of the world.

Street View imagery launched in 2007 with photos taken by cameras perched on cars. That's still the mainstay of the project, but there's much more to it now, and Google was showing off its methods at its Google I/O 2013 developer show here this week.

Exhibits included not just a car, but also a snowmobile, tricycle, backpack, trolley, and self-propelled underwater … Read more

SAN FRANCISCO -- Google is nearly done with its VP9 video technology, and it wants the world to use it.

At its Google I/O conference Wednesday, company employees made the case for the royalty-free, open-source technology as a higher-quality alternative to today's dominant video codec, H.264. Moving to VP9 -- available now in testing on Chrome and YouTube -- will save bandwidth costs.

"If you adopt VP9, as you can very quickly, you'll have tremendous advantages over anyone else out there using H.264 or VP8, (its predecessor)," said VP9 engineer Ronald Bultje in … Read more

SAN FRANCISCO -- Everybody knows that YouTube is growing, but Google revealed on Wednesday just how big it's gotten.

Matt Frost, senior business product manager for the Chrome Web Media Team, listed these statistics at the Google I/O show for developers:

• More than 1 billion monthly users;

• More than 4 billion video views per day;

• More than 6 billion hours of video watched per month;

• More than 72 hours of video uploaded each minute

• And 25 percent of consumption is with mobile devices.

In addition, Frost said that HD video is "becoming dominant."

That's obviously … Read more

Google released Go 1.1 Monday, promising faster software for programmers who use the language.

"We have made optimizations in the compiler and linker, garbage collector, goroutine scheduler, map implementation, and parts of the standard library," said Andrew Gerrand in a blog post. "It is likely that your Go code will run noticeably faster when built with Go 1.1."

Google made the announcement just before the Google I/O show in San Francisco. The company plans to detail Go at the developer-oriented conference, including a session on writing Go programs on Google App Engine, a … Read more

With newer technologies such as Android and more recently Glass, the scope of Google I/O has expanded dramatically since the first show in 2008. But Google, born on the Web, is keeping the browser at the heart of the show.

Five years ago, Google wanted to advance what Web-based software could do. The company could take steps such as improving interfaces to its own online services so developers could build better sites, and it promoted the Gears browser plug-in designed to beef up browser abilities with features like offline app support and the ability.

Two things make that different … Read more

Mozilla has a deal for programmers: We'll supply the phones if you supply the apps.

In an effort to ensure there will be good Firefox OS apps in the Firefox Marketplace, Mozilla is offering developer phones to programmers who have compelling ideas for software. In a blog post Thursday, Mozilla employee Havi Hoffman tried to drum up interest:

If you can show you've got a great app idea and the skill to build it, we'd love to see your apps in the Marketplace when the Firefox OS launch begins later this summer. And to sweeten the deal, … Read more

Performance improvements over the last year mean Web pages measured by the Google Analytics service load significantly faster for people using mobile devices.

The pages load 30 percent faster for mobile browsers now than they did a year ago, Steve Souders, Google's head performance engineer, said in a presentation earlier. And for desktop browser users, the pages load 3.5 percent faster.

Mobile Web performance -- often impaired by big Web pages, slower networks, and limited processors -- can be irritating. The slower a Web page responds, the less people use it, and that's a problem for a … Read more
