Submission + - HP reverses course on PCs (

tverbeek writes: Not to be outdone by Netflix's bumpercar strategic planning, HP's current CEO has announced that they will not be divesting themselves of their Personal System Group, which makes some of the world's bestselling laptops and desktops. No word on what this means (if anything) for the fate of WebOS and its mobile devices.

Submission + - Re-programming the thermostat (

OzPeter writes: As reported in WA Today, Tony Fadell of iPod fame has been using Nest Labs to design and build a thermostat that learns how you live in your house by following how you manually change the temperature. Once you have taught it how to behave (How the Nest learning Thermostat learns), it then can schedule temperature changes that suit your lifestyle, and help you cut down on energy costs.

Submission + - Airplanes Cause Accidental Cloud Seeding (

An anonymous reader writes: A new study by a team of US researchers found that commercial and private jetliners may be contributing to a form of accidental cloud seeding. When an airplane flies through a cloud, its propellers cause the expansion and cooling of the air behind them which can cause water droplets to spontaneously cool and crystals to form. The aircraft sets off a chain reaction in the cloud that can continue on for hours after the plane has passed by. The researchers also discovered that this phenomenon is more common near the poles, where many of Earth’s weather monitoring systems are, and it could be skewing data that research teams are gathering in those areas.

Submission + - Smallest Electric Plane Breaks Speed Record (

MikeChino writes: The mighty Cri-Cri micro plane just broke the electric plane speed record at the Paris Air Show. The plane first took to the skies last September when it drew a lot of attention for its petite size and impressive flying capabilities. Now the developers and pilot can add “world’s fastest” to the list as they hit 283 kilometers per hour, running on only electricity and two 35-horsepower engines.

Submission + - Controlling WiFi radio 'nap-time' saves power (

alphadogg writes: A Duke University grad student has come up with a way to double, or more, battery life in Wi-Fi devices, without any changes needed on the device itself. Essentially, the technique regulates how long and when client radios sleep, so that data transfers can be scheduled more efficiently. In a test using eight laptops and nine Nexus One Android-based smartphones on an 802.11n network, the researchers found that the scheduling technique, dubbed SleepWell, resulted in energy reductions of 38% to 51% across a variety of online applications, including YouTube, Pandora and Internet radio, and TCP bulk data transfers. What’s more, they found that as the quality of radio links degrades, the relative energy gains are even higher.

Submission + - WoW Free to Play: Preemptive Strike vs. Star Wars? ( 2

donniebaseball23 writes: World of Warcraft Starter Edition was unveiled earlier this week, revealing Blizzard's new scheme to hook players into WoW if they're not already playing the hugely popular MMO. The new edition allows players to try the game for free until they've reached level 20, and it could be seen as a strategic move to counter growing competition in the MMO space, especially BioWare's upcoming Star Wars: The Old Republic. Wedbush Securities analyst Michael Pachter told IndustryGamers, "I absolutely think it's a pre-emptive move against the Star Wars launch. They aren't giving away anything to existing subscribers (except for the Burning Crusade expansion), and it's a great hook to attract new subscribers. People new to MMOs will have to think about whether to buy Star Wars or WoW, it's actually a brilliant strategic move."

Submission + - Google Loses Bedrock Suit, All Linux May Infringe (

blair1q writes: cnet reports that Google has lost the lawsuit brought by Bedrock, is infringing on Patent 5,893,120 "Methods and apparatus for information storage and retrieval using a hashing technique with external chaining and on-the-fly removal of expired data," and has exposed the Linux kernel, in which the infringing code reportedly appears, to liability for patent-license fees. RedHat also participated in the suit, arguing that the patent was invalid, but the court decided otherwise.

Submission + - Mars Orbiter Finds Buried Dry Ice Lake (

RedEaredSlider writes: NASA's Mars Reconnaissance Orbiter has found a giant buried deposit of dry ice, which could be evidence that Mars once had a thicker atmosphere and was able to have more water on its surface.

The orbiter's ground-penetrating radar found the dry ice, which is frozen carbon dioxide, near the planet's south pole. The scientists think that when Mars' axial tilt increases, the carbon dioxide turns into a gas, thickening the atmosphere. The result would be more intense dust storms, but also a wider range of areas where liquid water could exist.


Submission + - 6 Upcoming Dual-Core Android Smartphones (

i4u writes: This year has seen the explosive birth of a new kind of mobile device. Dual-core superphones are almost impossibly powerful compared to even the immediate previous generation of handsets. There's a reason the Atrix launched with a laptop dock as a key feature. 'Mobile' doesn't mean 'underpowered' anymore. If you want more out of your smartphone, you want one of these six behemoths.

But which?


Submission + - European Copyright Term Extension Review a go? (

An anonymous reader writes: Earlier Slashdot reported on Denmark's sudden and unexpected about-face regarding the proposed European copyright term extension on musical recordings from 50 to 70 years. Pirate Party MEP Christian Engström quickly reacted drumming up (online) media attention to this issue. Today he announced the 40 signatures he needed to put the proposal back for review by the current European Parliament. It's now up to the European public to influence their politicians.

Submission + - Microsoft, Nokia Finally Sign Definitive Agreement (

An anonymous reader writes: Microsoft and Nokia today announced the signing of a definitive agreement regarding their global mobile ecosystem partnership. Two months ago, Nokia announced that it was choosing Microsoft's Windows Phone as its primary smartphone platform but that the two companies still need to work out the details of the deal. A lot has happened since then, but apparently the agreement was completed ahead of schedule, according to the duo.

There are three points that we think are worth pointing out separately. We already know that Microsoft and Nokia will work together to reach out to developers, but the two have agreed to make Windows Phone developer registration free for all Nokia developers. There are also plans to open a new Nokia-branded global application store that leverages the Windows Phone Marketplace infrastructure so that developers can publish and distribute applications through a single developer portal to consumers that use Windows Phone, Symbian, and Series 40 devices. Lastly, Nokia will contribute its expertise in operator billing to ensure participants in the Windows Phone ecosystem can take advantage of Nokia's billing agreements with 112 operators in 36 markets.


Submission + - Smart Windows Embed Free Solar Panels (

An anonymous reader writes: Using a cheap plastic solar-cell formulation--protected inside standard double-pane glass--all the windows of the world could soon become solar panels, according to MIT: 'All the windows in every building in the world should be generating electricity for use on-the-spot to minimize electric bills, according to Massachusetts Institute of Technology. To do that, researchers there have demonstrated transparent solar cells that harvest the heat of the sun while allowing the visible light to pass through.'

Within three years, MIT estimates that its 'smart windows' will be available for new construction and within a decade as pull-down window shades that can be retrofit over existing windows. Sign me up!

Submission + - Reports 100k Subscribers (

An anonymous reader writes: Despite Slashdot (and much of the internet) ridiculing the New York Times for its archaic and overpriced paywall, the newspaper has reported an excess of one hundred thousand subscribers so far. Even as loopholes are offered, the New York Times has some support which they will need as print revenues dwindle (falling a staggering 57.6 percent during the year's first quarter).

Do not underestimate the value of print statements for debugging.
