4G' Sony Tablet P coming to AT&T on March 4th for $400

Sony's odd, dual-screened, folding Tablet P is finally getting a "4G" version here the US, courtesy of AT&T. In this case, those 4G speeds are being "delivered" by an HSPA+ radio, a fact that carrier managed to bury in the PR. The Honeycomb device will be bringing its unique set of 5.5-inch screens to Ma Bell starting March 4th for the rather steep price of $400 with a two year contract. If you don't want to sign your soul over you can pick one up unsubsidized for $550, which is still quite a bit less than the cost of importing one of its £500 UK siblings.

Join us for Microsoft's Windows 8 press conference tomorrow at 9:30am EST!

If you're Microsoft and in the process of overhauling Windows so that it's equally at home on PCs and tablets, it would make sense to unveil a semi-final version at the world's premier wireless show. That's exactly what's going to happen tomorrow, when the company's executive team takes the stage here in Barcelona to show off all the changes it's made to Win8 since we got hands-on with the Developer Preview five months ago. Though we still won't know tomorrow what the final version will look like, we'll have a much firmer idea, as this will be the first version available to the general Windows-using populace. So what does Redmond have up its sleeve? Will the Windows Store open for business? A first look at some native touch-friendly apps? And what's to become of the Start button? Bookmark this page and come back tomorrow at 9:30am EST (3:30pm local time), when we'll be firing off up-to-the-minute updates. See you then!

what is the lunar eclipse

Introduction

An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer.

Totality solar eclipse
The term eclipse is most often used to describe either a solar eclipse, when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the shadow of Earth. However, it can also refer to such events beyond the Earth-Moon system: for example, a planet moving into the shadow cast by one of its moons, a moon passing into the shadow cast by its host planet, or a moon passing into the shadow of another moon. A binary star system can also produce eclipses if the plane of their orbit intersects the position of the observer.



Lunar eclipses occur when the Moon passes through the Earth's shadow. Since this occurs only when the Moon is on the far side of the Earth from the Sun, lunar eclipses only occur when there is a full moon. Unlike a solar eclipse, an eclipse of the Moon can be observed from nearly an entire hemisphere. For this reason it is much more common to observe a lunar eclipse from a given location. A lunar eclipse also lasts longer, taking several hours to complete, with totality itself usually averaging anywhere from about 30 minutes to over an hour.

The progression of a lunar eclipse.
There are three types of lunar eclipses: penumbral, when the Moon crosses only the Earth's penumbra; partial, when the Moon crosses partially into the Earth's umbra; and total, when the Moon circles entirely within the Earth's umbra. Total lunar eclipses pass through all three phases. Even during a total lunar eclipse, however, the Moon is not completely dark. Sunlight refracted through the Earth's atmosphere intersects the umbra and provides a faint illumination. Much as in a sunset, the atmosphere tends to scatter light with shorter wavelengths, so the illumination of the Moon by refracted light has a red hue, thus the phrase 'Blood Moon' is often found in descriptions of such lunar events as far back as eclipses are recorded.

Doodle Defense game uses Kinect to turn white boards into displays, dry-erase markers into weapons

Tower defense games have been done in damn near every way possible: on consoles, mobile apps, and online flash-based games. However, there's a new Kickstarter project, called Doodle Defense, that's putting a new spin on that simple gaming idea using some open source algorithms, a whiteboard, computer, Kinect and a projector. The game works by projecting the battlefield and bad guys on the whiteboard, while users can draw in obstacles using a black marker and towers of varied attack abilities in red, green, and blue. Kinect tracks where your drawings are onscreen, and reroutes the invaders accordingly, while also keeping track of how much ink you have left to use. Check out the video after the break to see the game in action

Auraslate opens Android tablets up to developers, welcomes mischief

HTC aside, not every manufacturer is willing, ready and committed to opening up its device portfolio to the idle hands of hackers. Which is why Auraslate, a recently launched start-up, is stepping in to fill that void, instituting a sea change in how devs translate their unsanctioned software concepts into actual end user products. To do this, the humble outfit's offering up 7- and 10-inch Android tablets that range in price from $139 to $270 and come loaded up with an ARM Cortex A9 CPU, 4GB storage and a Gorilla Glass-coated capacitive touchscreen. Prospective haxxors can choose between two configurations available on the site: an Advance Development Kit which includes a source code disk and a cheaper Novice option. For the money, you'll get that aforementioned hardware, peripherals (usb plug, power adapter), as well as access to Aura's forums and ROM refreshes, although ICS is limited to its top shelf Lifepad 1026. So if you're tired of damning the Man with every OEM-issued, security-patching update and just want to be left to your coding best, it might be wise to bask in this company's glow.

Samsung's new SD cards look too good to hide inside a DSLR

We've never been too fussed with how our storage looks -- it's rare that our SD cards linger too long outside the camera anyway. However, for you genius-level aesthetes who demand your internals are as beautiful as your externals, Samsung's got your back. It's releasing a line of SD and microSD cards with a stylish brushed metal body in silver or black that, frankly, looks shinier than whatever they'll be nestled inside. Just like Ryan Gosling, the cards are both pretty and pretty tough -- able to withstand 24 hours in water, 3,200 pounds of pressure or being left in an MRI machine with a power of 10,000 gauss, which we're always doing. After the interval, we've got pricing and stats for each unit (speed improves greatly if you plump for a 4GB card or higher) plus a little PR paperwork.

Amazon's second-gen, possibly larger Kindle Fire to set off at end of Q2?

Still anticipating the Kindle Fire's successor? Well, here's some gossip from the Far East for you Bezos fans. According to the well-connected China Times of Taiwan, it's been informed by parts suppliers that Amazon's next tablet does not yet have a finalized specification, though it hinted that a 10-inch OEM device from Foxconn could be a potential candidate. Amazon's chain of manufacturers -- including Quanta, ACES, Prime View, Singatron, CviLux and the newly added Foxconn -- is allegedly scheduled to supply sample parts in March, followed by mass production (assembled by Quanta and Foxconn, naturally) in May or June before releasing to market by the end of Q2.

Additionally, China Times understands that as an attempt to further reduce manufacturing costs, Amazon will also be personally picking and approving parts; as opposed to the olden days where Quanta took full care of the first Kindle Fire. This is surely a bad sign for Quanta in the short run, but hey, cheaper tablets sell well. The real question is: do people actually want a larger Kindle Fire? We're a tad skeptical at this point.

Microsoft reveals Windows 8's new logo: 'It's a window... not a flag'

Microsoft is making plenty of big changes with its Windows 8 operating system, and that has now also extended to a new logo. As explained by Microsoft's Sam Moreau in a post on the official Windows blog, the logo was created with the help of the design agency Pentagram, which posed a simple question when it began on the project: "your name is Windows. Why are you a flag?" That discussion eventually led to the four-paned window you see above, which not only looks more like a window than the previous logos, but clearly echoes the company's new Metro design language. Microsoft also notes that the logo is "authentically digital," and says it will welcome you with a slight tilt and change color based on your desktop.

Google's Dart lands in Chromium tech preview

Leaves weren't the only things flying around Mountain View last Autumn if you remember, Google also unleashed its Dart programming language. Now, developers can get their hands on a tech preview version of Chromium, with the Dart virtual machine baked right in. There are Mac and Linux binaries available today, but no details about other platforms (ahem Windows) at this time. The preview lets you run your programs directly on the Dart VM, skipping the separate compilation stage. While it's just for developers at the minute, there are plans to include this in standard Chrome releases in the future.

Google Screenwise panel will pay you to track your every move online

Don't mind letting Google watch your every click while browsing the web? Awesome, because the folks in Mountain View want to pay you for letting them do just that. The company is recruiting panelists for a project it's calling Screenwise, a program that will give the internet behemoth more insight into how the general public uses the interwebs day in and day out. Once you opt in, you'll receive a $5 gift card code to Amazon and for up to a year, you'll get additional spending money every three months. But how will The Goog track your mouse clicks? Just before getting paid, you'll have to download a browser extension that will keep an eye on things and send your data back to the mothership. If you're looking to make a little more dough, Ars Technica reports that you'll be able to opt for a more lucrative hardware monitoring option. Here, you'll have to install the Screenwise Data Collector (pictured above) on your home network; however, the pay out is an initial Benjamin and $20 for every month you participate. Sound like something you'd want in on? Hit the source link below to be notified when registration opens.

Sony promises eight more NEX E-mount lenses by the end of 2013, doesn't elaborate

Have you been holding out on that NEX purchase because of the currently limited E-mount lens selection? Well, Sony's got some good news for you -- there will soon be eight additional lenses to choose from (for a total of 15), with all models making it into circulation by the end of 2013. That's still no match for the hundreds of optics available for Canon or Nikon DSLRs, but you'll at least be able to build a collection that covers (almost) all of your bases. Sony hasn't detailed any of these upcoming models, but the company's chart above lists a few categories, including a High Performance Standard Zoom in the pricey Zeiss category, along with High-magnification, Standard, Wide Angle and Mid-magnification Zooms. There will also be a trio of prime lenses, including a Large Aperture Standard lens, a Middle Telephoto and a "Snap" (pancake) optic. We're just as anxious as you to find out exactly what Sony has in mind for each of these categories, but you should at least take some comfort in knowing that the E-mount collection is far from complete.

Google Chrome update brings speedier browsing, enhanced security, joy

The week isn't quite over yet, but it's already shaping up to be a busy one for Google Chrome. After finally bringing its browser to Android on Tuesday, Google yesterday announced an update for the original desktop version, promising faster browsing and enhanced security. More specifically, this new Stable release features a revamped omnibox that will now pre-render pages as a user types in a URL or search query, allowing for faster load times. Google has also tweaked its Safe Browsing feature, which will now automatically scan downloaded files for malware, with an especially sharp focus on any ".exe." or ".msi" files. To determine the safety of a given file, the browser will compare it against a list of publishers and files known to be safe. If it doesn't show up there, Chrome will then consult Google for more information. If the file proves suspicious, it'll warn the user and recommend deleting it. Google added that it's working on an update for its Chrome OS, as well, promising a new image editor and Verizon 3G activation portal, though there's no word yet on when that might roll out.
