Building on Verify apps, which already protects people when they're installing apps outside of Google Play at the time of installation, we're rolling out a new enhancement which will now continually check devices to make sure that all apps are behaving in a safe manner, even after installation. In the last year, the foundation of this service - Verify apps - has been used more than 4 billion times to check apps at the time of install. This enhancement will take that protection even further, using Android's powerful app scanning system developed by the Android security and Safe Browsing teams.

The Module Developers Kit (MDK) defines the Ara platform for module developers and provides reference implementations for various design features. The Ara platform consists of an on-device packet-switched data network based on the MIPI UniPro protocol stack, a flexible power bus, and an elegant industrial design that mechanically unites the modules with an endoskeleton. Throughout 2014, the Project Ara team will be working on a series of alpha and beta MDK releases. We welcome developer input to the MDK: either through the Ara Module Developers mailing list/forum or at one of the series of Developers Conferences.

It wasn't meant to be this way. Windows XP, now no longer supported, wasn't meant to be popular. For all its popularity and sustained usage, people seem to have forgotten something important about it: it sucked.

The Ars forums are a place for geeks to hang out and chat about tech, and especially in the light of the hostility shown towards Windows 8, we thought it might be fun to take a look at how our forum dwellers reacted when first introduced to Microsoft's ancient operating system.

Fortunately though, Mozilla keeps on trucking, and Firefox OS appears to be constantly improving. The latest version available is 1.3.0, with the latest preview being 1.4. Now, sources from China have gotten their hands on a ton of screenshots and new information regarding Firefox OS 2.0, and we must say, the UI looks quite pretty.

Heartbleed, a long-undiscovered bug in cryptographic software called OpenSSL that secures Web communications, may have left roughly two-thirds of the Web vulnerable to eavesdropping for the past two years. Heartbleed isn't your garden-variety vulnerability, so here's a quick guide to what it is, why it's so serious, and what you can do to keep your data safe.

It's finally here. After 12 years, 6 months, and 12 days on the market, Windows XP has hit its end of life. It will receive its last ever set of patches on Windows Update today, and for the most part, that will be that. Any flaws discovered from now on - and it's inevitable that some will be discovered - will never be publicly patched.

How bad is this going to be? It's probably going to be pretty bad. By some measures, about 28 percent of the Web-using public is still using Windows XP, and these systems are going to be ripe for exploitation.

It looks like the Internet of Things could be the next big computing battleground, and Microsoft seems willing to sacrifice a few battles in order to win that war. Facebook is chasing virtual reality; Google wants home automation, smartwatches, and internet-connected glasses. More than 200 billion devices are likely to be connected to the internet by 2020, a huge example of the way the technology industry will shift and new battles will emerge. Satya Nadella believes the future isn't Windows desktops, Windows tablets, and Windows Phones. It's not Windows everywhere, it's Microsoft everywhere, offering software and services for every device - including an entire world of interconnected devices that have yet to be built.

This map showing the locations of 280 million individual posts on Twitter shows a depressing divide in America: Tweets coming from Manhattan tend to come from iPhones. Tweets coming from Newark, N.J., tend to come from Android phones.

If you live in the New York metro area, you don't need to be told that Manhattan is where the region's rich people live, and the poor live in Newark. Manhattan's median income is $67,000 a year. Newark's is $17,000, according to U.S. Census data.

According to documents obtained exclusively by The Verge, Google is about to launch a renewed assault on your television set called Android TV. Major video app providers are building for the platform right now. Android TV may sound like a semantic difference - after all, Google TV was based on Android - but it's something very different. Android TV is no longer a crazy attempt to turn your TV into a bigger, more powerful smartphone. "Android TV is an entertainment interface, not a computing platform," writes Google. "It's all about finding and enjoying content with the least amount of friction." It will be "cinematic, fun, fluid, and fast."

What does that all mean? It means that Android TV will look and feel a lot more like the rest of the set top boxes on the market, including Apple TV, Amazon's Fire TV, and Roku.

Internal Apple documents from last April shown in court today paint the picture that the company was scrambling to identify and determine ways to compete with devices running Android, as well as keep sales of the iPhone from petering out amid growing competition.

Pages from a 2014 planning document last April, shown during a cross-examination of Apple's marketing chief Phil Schiller, noted that smartphone growth rates were declining, something that could impact iPhone sales. Worse yet, the document said, was growing consumer interest for less expensive, larger-screened smartphones, with a headline on the page reading "consumers want what we don't have."

Folks have been asking about our early Linux efforts and support for Valve's SteamOS and Steam Machines. We have good news for you! The 4.1 source code has initial support for running and packaging games for Linux and SteamOS. We love Linux!

Mozilla prides itself on being held to a different standard and, this past week, we didn't live up to it. We know why people are hurt and angry, and they are right: it's because we haven't stayed true to ourselves.

We didn’t act like you'd expect Mozilla to act. We didn't move fast enough to engage with people once the controversy started. We're sorry. We must do better.

Brendan Eich has chosen to step down from his role as CEO. He's made this decision for Mozilla and our community.

This project is actively developed by the WinJS developers working for Microsoft Open Technologies, in collaboration with the community of open source developers. Together we are dedicated to creating the best possible solution for HTML/JS/CSS application development.
