It takes a lot of energy for computing systems or data centers to patch up critical errors, but what if we devoted less power to fixing less urgent issues? That's the basic idea behind EnerJ -- a new power-saving system that could cut a chip's energy consumption by 90 percent, simply by prioritizing critical problems over those that are less threatening. Unlike, say, liquid cooling techniques, the University of Washington's framework focuses exclusively on the programming side of the equation and revolves around two interlocking pieces of code: one that handles crucial, precision-based tasks (e.g., password encryption), and another designed to deal with processes that can continue to function, even when facing small errors. The system's software would separate the two codes, meaning that energy from one section of the chip would never be used to fix a major problem that the other should address, while allowing engineers to more efficiently allocate voltage to each regi...

Angry Birds was designed to be played on a device that fits in your pocket, so playing the game projected on a wall doesn't exactly feel natural. Throw a life-size slingshot into the mix, though, and things really get zany. The slingshot was on hand at the University of Queensland (Australia) last night, and had apparently been "months in the making." Details are scant, so we're not sure exactly how the slingshot communicates with the game, but however it works, it appears able to do its thing fairly well -- with only a brief delay after release. This slingshot appearance may be a one-time deal, so if you want to try flicking the bird on the big screen, Angry Birds for Chrome (and a mouse) may be your best option for now.

Android 2.3 hit the web for Droid X owners earlier this week, but that update previously required a tethered, manual install. As of today, the update is available over the air, so cable-free purists can finally start cooking with Gingerbread on their Droid X handsets. We first saw 2.3 popping up on the device in March, but if you opted out of rooting your handset for an early look at the new OS, you can now get your feet wet with speedy navigation, a customizable dock, and an overhauled camera app.

Ideally, we'd do our smartphone software shopping free from the specter of malicious apps masquerading as useful ones. This past weekend, however, 26 apps in theAndroid Market were discovered to be packing pernicious code called Droid Dream Light. Apparently, the dastardly devs who made the malware took existing apps and modified them to send details (including IMEI and IMSI info) about the infected handset to a remote server upon receiving a call. The code can also download and cue new package installations, but it needs user approval to do so. Google promptly pulled the offending apps, but their appearance serves as another reminder to be careful when downloading software on your smartphone -- prudence demands minding your app permissions, lest your little green bot start stealing your personal info.

Well, this was inevitable. After Sprint's website snafu outing its Android 2.3 intentions for the EVO 4G, we've received evidence that points to June 6th as its release date. Better yet, if you're willing to manually check for its availability, you might even find a happy surprise this Friday. In addition to Gingerbread, users will find SMS and Gmail fixes, along with a tweak to the phone's power management software. Hopefully you've got WiMAX, because this update is coming over-the-air. Should everything go according to plan, users will have less than a week to say goodbye to Froyo. It's a trusty companion for sure, but that spicy aroma is quite enticing. Hit the break for some corroborating clues.

It's been nearly twenty years since Linus Torvalds let loose Linux on an unsuspecting world, and yesterday he finally updated the open source OS kernel to version 3.0. This third iteration, currently named 3.0.0-rc1, comes 15 years after 2.0 first hit the web and brings driver support for Microsoft Kinect -- a move that should have visions of sugar plum fairies (or maybe just Android avatars) dancing in hackers' heads. Also included is code optimized for AMD's Fusion and Intel's Ivy and Sandy Bridgesilicon, and some updated graphics drivers, too. Despite these tasty new treats, Torvalds is quick to point out that this new release is an evolutionary change and unleashing the big three-oh was all about moving into a third decade of distribution, not about overhauling the OS. There's still work to be done, as it is a release candidate in need of refinement, but curious coders can grab the latest Linux at the Kernel.org  source link be...

Still bothering with that unofficial 2.3 update for your comparatively monstrous Droid X? Good news, eager beaver; right on cue, the bona fide Gingerbread update is rolling out to select Droid X owners this weekend, and if you aren't lucky enough to be included in the initial soak test, you can take matters into your own hands by visiting the source links below. Per usual, we'd caution against a manual install for those who aren't familiar with the process, particularly since the masses should receive it as the week forges on. Naturally, the v2.3.3 changes are subtle (at least in comparison to the changes seen in the leap from Eclair to Froyo), but hey -- an update's an update. Droid-Life (1) ,  (2) ,  Android Central

'Tis a sad day in the world of Google... at least for developers who use any of a handful of ill-fated APIs. As the search giant's API list has grown in recent months, it's making the decision to cull a few in the effort of "spring cleaning." In fact, a grand total of seven new APIs were launched during Google I/Oalone, but it looks as if the end is nigh for the Blog Search API, Books Data API, Image Search API, News Search API, Patent Search API, Safe Browsing API (v1 only), Translate API, Transliterate API, Video Search API and Virtual Keyboard API. Of those, Wave is most unsurprising, but Translate likely hurts the most -- particularly for jetsetters who relied on those baked-in services to wrap their heads around various tongues. According to Goog, the Translate API has been officially deprecated "due to the substantial economic burden caused by extensive abuse." A pretty ominous phrase, to be sure, and further proof that a few rotten apples can rui...

Last month we asked for a "funny pages" display in Google's next release of Maps that shows a thick dotted line depicting where we've traveled, but it appears the folks at El Goog had a different agenda in mind for version 5.5. This time around, we see a few redesigns as well as some streamlined Latitude features. First, check-ins and ratings have now been added to the Places page, giving you one extra point of access; you also now have the option of changing your home or work address within your Latitude Location History, in case you ever move or just like to roam from place to place. Last but not least, Google Maps 5.5 for Android also offers reorganized transit station pages that now list off upcoming departures, transit lines serving that particular station, and links to other stops nearby. Though not a substantial upgrade from previous versions, it's still impressive that Google pushed it out less than a month after 5.4. The new update is available as a free...

Yes, it's another store within a store at Amazon, this time a Mac Download Store. While software downloads certainly aren't anything new for the online retailer, the Mac store does actually boast a wider variety of titles than Amazon's Windows download section, including games like  Dragon Age: Origins and  Civilization V , and applications like Microsoft Office and Adobe Photoshop Elements. All told, there's more than 250 titles currently available -- not exactly a rival to Apple's own Mac App Store, but a more than respectable start. Of course, no store launch is complete without a sale, and Amazon has kicked things off with two: a free download of Airport Mania, and $5 off your first paid download. Hit up the source link below to check it out. Amazon

We've heard an awful lot about a Windows tablet OS this past year, with stirrings of a 2012 launch -- heck, even Steve Ballmer's fanned the flames of speculation -- and now the rumor mill's been set in motion with word of an impending preview expected next week. According to  Bloomberg , three sources have confirmed Microsoft's plan to flaunt the much-anticipated UI, possibly at upcoming appearances at AllThingsD and Computex. The showcase is supposedly set to run the touchscreen-enabled software on a Tegra-equipped machine. We'd previously reported on stirrings of a June demo. Considering all the evidence that's stacked up over the past few months, we'd say 2012 is looking like a rather practical target. Business Insider Bloomberg

We've been hearing rumors for a while that Twitter was looking to make TweetDeck a member of its flock, and now, the blue bird crew has made it official.  All Things D  reports that the deal was done for between $40 to 50 million, and that TweetDeck CEO Iain Dodsworth will stay on to run the platform. In its official announcement, Twitter said it will continue to "invest in the TweetDeck that users know and love" -- time will tell if the new boss birdie is a boon or bane for the popular tweet tracking app. Twitter

We're still waiting to get our first big bite of the full Mango experience after this morning's liveblog, but we were able to get a quick hands-on with a few of the apps making use of the operating system's new features. Chief among them is the History Channel app, which is making use of the augmented reality features that have been enabled. Using the internal gyro and accelerometer the device was able to overlay landmarks, which with a tap can be added to the phones home screen -- you know, in case you really want to know what's up at the Brooklyn Bridge. We also got a look at the updated Weather Channel app, which will not identify cloud types using any augmented reality trickery, but will give you quick and easy access to what's up -- and about to start falling. Check out the pics below, and get ready for a video after the break. Weather Channel and History Channel apps for Windows Phone Mango (hands-on)

We're done listening, it's time to start doing. Microsoft had a number of Windows Phone Mango devices scattered about after this morning's intimate event concluded. So we grabbed one, went somewhere quiet, and got a little more intimate with the operating system itself, checking out the new hubs, groups, and Bing Vision search that should make cross-shopping a whole lot easier. Join us, won't you, to see what Mango is -- and what it isn't. Windows Phone Mango hands-on! First of all, Mango is  not  necessarily Windows Phone 7.1. Microsoft simply had to get the SDK ready to go and, well, they "had to call it something." So, 7.1 is that something, a number applied to the SDK that we have a feeling will stick to the OS as well, but Microsoft is still far from carving that version into stone. We also got a little more information about the Dell situation, that simply the company wasn't quite ready to commit to being on the Mango bandwagon. So, don...

Back in January, Gearbox Software released a  Duke Nukem Forever  trailer, and our inner 13 year-old -- only a lascivious gleam in his father's eye when the game was first announced! -- thrilled to its potty humor, gratuitous violence, and mosaic-obscured lady parts. We were skeptical about the promised May release date, since  DNF  has long been gaming's answer to  Chinese Democracy , and sure enough that got bumped to June 10 (international) and 14 (North America). But now the game has gone gold, meaning real-life physical copies, rather than just one of gaming's longest running vaporware jokes. No confirmation that the game will ship via unicorn, but for more details devour the press release after the break. Joystiq

Google recently rolled out the beta release of Chrome 12, and now Cr-48 owners are getting a matching version of Chrome OS. This latest version, 0.12.433.48, brings bug fixes, Flash 10.2.158.22, a file manager context menu, and some spiffy new icons and avatars to its browser-based UI. We grabbed the update on our own Google-fied laptops and got some pics of the beta's new bits for your viewing pleasure. We're still getting acquainted with all of the changes, so if you've also copped the new Chrome OS let us know how it's treating you in the comments. Chrome OS 12 update Google

Android, as Andy Rubin (no relation) has pointed out on multiple occasions, plays a game of numbers. And at Google I/O, the company carrying on its development shared some large ones: 100 million activated devices with 400,000 being added each day. However, like in many games, different players can catch up or overtake each other at different points. Just ask Nokia and RIM. To stay on top, operating system vendors implement strategies that lock consumers in. The more money consumers sink into iPhone apps, for example, the more incentive they have to stay with that platform; the same is true for accessories that use Apple's 30-pin dock connector that has been around since the third-generation iPod. With Android having become the lead operating system for every smartphone company that licenses its OS with the notable exception of Nokia (which nearly did), Google showed that it's intent not just on moving Android into other devices with sufficient computing hors...
