drag2share: HotelTonight app now lets you preview room availability seven days ahead

Source: http://www.engadget.com/2014/04/15/hoteltonight/

HotelTonight's namesake feature is also holding it back: You can only book a room beginning at 9AM on the day of check-in. If you're planning to arrive during a major event, say, in Los Angeles during E3 or Rio during Carnival, landing without a confirmed room can add to the already stressful travel process. But the folks at HotelTonight have a good idea of whether or not you'll be able to find a room, and the team's now ready to share that info with you. Now, when you open up the iOS app, Look Ahead will let you preview room pricing and availability for the next seven days. The app will even give you a heads up if there's an event in town, so you can be aware of higher than normal rates, or opt to change your plans to avoid the crowds. Look Ahead is available today in Chicago, Dallas, Las Vegas, Los Angeles, Miami, New York, San Diego, San Francisco and Washington, DC. You'll need to have an iPhone to take advantage, but expect the feature to hit Android soon.

drag2share: Google's Project Ara wants to revolutionize the smartphone industry within a year

Source: http://www.engadget.com/2014/04/15/project-ara-modular-smartphone/

The night before Google's Advanced Technology and Projects (ATAP) division was supposed to show off the one and only functional Project Ara prototype to a room full of eager developers, someone dropped the phone and broke the display. At any other product reveal, this worst-case scenario would be a nightmare come true. Not to Google: The company made lemonade out of a lemon by turning it into a selling point for the modular smartphone. A year from now, painful situations like this can be easily fixed by simply buying a new display and swapping out the broken one.

Not that last night's fiasco would've made much of a difference. Attendees at this week's Project Ara developer conference wouldn't have been able to boot up the prototype and play around with it like any typical smartphone -- in this case, "functional" is not the same as "functioning" -- but at least it would've made for a better presentation. Regardless of how it looked, however, we were able to briefly handle the Project Ara prototype and some of its first modules. To be clear, this is an extremely early model and there's a long way to go before it sees the light of day, but it at least allows us to get a good glimpse of what's to come over the next year as Ara continues to prepare for launch.

Project Ara brings the modular smartphone from concept to a reality; it almost seems like it should've made a cameo in The Lego Movie. The Ara consists of a metal endoskeleton, which is essentially the spine of the phone, and slots for replaceable components known as modules, which look a lot like tiles. (If you're reminded of Windows Phone when looking at the back, you won't be the first.) These tiled modules can include anything that makes your phone tick (processor, RAM, WiFi, power jack, baseband, display and battery, for instance), as well as plenty of other features like your camera, speakers and storage space. Each module will connect to the other working parts through capacitive interconnects, which are essentially wireless pads that are smaller than standard pins. Electropermanent magnets not only hold modules in place, but they also act as a toggle switch, which allows you to easily turn that element on and off. As you might already imagine, all modules can be swapped out at your convenience. ATAP plans to feature Ara in three different sizes, ranging from a smaller six-module option to a large-screened model with more modules.

At first blush, it almost sounds like this project only appeals to the same consumers that enjoy building their own computers from scratch, but ATAP insists that it'll transform emerging markets -- more specifically, the 5 billion people on Earth who own feature phones, but cannot afford to get anything more expensive. Today, the division announced that it's planning to ship a "Grey Phone," which is simply a prepackaged device that comes with only a screen, processor and WiFi module. From there, users can easily add and take away components as they see fit. It'll be relatively cheap -- the product would cost Google $50 to make, though retail price hasn't been determined yet -- and users on a tight budget can easily add or upgrade modules whenever they can afford to do so.

Longevity is another huge factor; whereas most smartphones today can barely make it through a two-year contract, Ara is meant to last for several years. This means it'll likely be much less expensive over the long run, and fewer phones will wind up in dumpsters.

According to ATAP, a device like Ara will also bring power of choice to consumer hands. Buying a smartphone often feels like a gamble -- a matter of sacrificing some features in favor of others. With Ara, you'll finally be able to determine exactly what kind of stuff you want in your phone. In essence, it sounds like Google's hoping to "disrupt" the traditional phone makers like Samsung, HTC and LG (as well as carriers), since the average consumer wouldn't need to go through those companies to buy a phone anymore.

When it comes to what kind of modules would be available, the sky's the limit. ATAP has already begun offering a development kit to anyone who wants to put together modules of their own, so there are plenty of possible use cases. One example shown was a pulse oximeter, featured in a long module that extended beyond the rest of the phone's chassis; there was a thick camera module that could easily be swapped out with different kinds of lenses; and we even listened to developers as they floated the idea of a credit card reader similar to a Square dongle. As of this week, it's now up to these partners and devs to explore the space and figure out how to make Ara successful.

This all sounds fine and dandy, but it doesn't come without a setback or two. Despite ATAP's efforts, it's still larger, heavier and thicker than your run-of-the-mill smartphone, and there are some concerns with battery efficiency (although the ability to hot-swap batteries certainly helps). Naturally, the team understands that such matters could be a turnoff for potential buyers, so they hope to resolve these issues by the time the next prototype comes around later this year.

Project Ara is halfway through a two-year mission. The deadline is a driving motivation for the handful of full-time employees and contractors involved in the project, as the expected timeframe was brought up several times during today's conference. There isn't any time for delays, which makes this project even more exciting -- if it's going to happen, it has to be ready to go this time next year. Not only is ATAP facing a ticking clock, but it's also doing so with a pretty hefty to-do list: It has to entice developers, conduct demonstrations at convincing scales and get consumers interested in taking a chance on a brand-new type of smartphone. It's not going to be easy, but the journey will be fascinating to watch.

drag2share: Here's the software that helps Edward Snowden avoid the NSA

Source: http://www.engadget.com/2014/04/15/edward-snowden-software-choice/

Edward Snowden

Edward Snowden hasn't escaped the NSA's watchful eyes purely by exploiting lax security -- he also uses the right software. We now know that he communicates with the media using Tails, a customized version of Linux that makes it easy to use Tor's anonymity network and other tools that keep data private. The software loads from external drives and doesn't store anything locally, so it's relatively trivial for Snowden and his contacts to discuss leaks without leaving a trace.

The underlying technology isn't completely original, and it's not perfect; Tails' open source code and anonymous developer base help resist pressure to include spy-friendly back doors, but there are still potential security holes. Users also have to be careful with their choices of internet services while using Tails, as the wrong ones could give the whole game away. Even with those concerns in mind, the software is a big help to Snowden, journalists and others that want to keep their conversations under wraps with a minimum of effort.

drag2share: Sony has a 4K TV for every budget (that's at least $2,099)

Source: http://www.engadget.com/2014/04/15/sony-2014-4k-tv-pricing/

Sony 4K TV

Sony has nailed down the final launch details for its newest 4K Bravia TVs, and surprise -- they just might be affordable this year. The "entry-level" XBR-X850B series will start at a relatively frugal $2,099 for a 49-inch model, with prices peaking at $5,499 for a 70-inch set. If you've got a bit more cash and want upgrades to both audio and wall mounting, the XBR-X900B line starts at $3,999 for a 55-inch set and scales up to $8,999 for a 79-inch variant. There's still a couple of models for the money-is-no-object crowd, of course. The improved LED lighting of the 65-inch XBR-X950B will set you back $7,999, while the display's 85-inch sibling costs an eye-watering $24,999. All of the 4K sets ship in June.

The company also hasn't forgotten about those with earlier Bravia sets. It's releasing an updated version of its 4K media player, the FMP-X10, this summer. There's no pricing just yet, but it has 1TB of storage for downloaded Video Unlimited movies and supports the same 4K Netflix movies as newer Bravia TVs. The previous model sold for $699, although Sony has bundled it with sets for free or at a discount -- whatever the new one costs, you may not have to pay full price.

drag2share: With This Robotics Program Thriving In Public Schools, It's 'Cool To Make Mistakes Again'

Source: http://www.businessinsider.com/teq-nao-robots-in-public-schools-2014-4

Joe Dixon is Chief Learning Officer of Teq, a professional development company for teachers that aims to "champion the continued evolution of the modern classroom." Lately that means getting lots of robots into the hands of schoolkids.

Specifically, Teq is bring the NAO robot, a small humanoid from Aldebaran Robotics, into the classroom for educational applications. The bot is already in widespread use as a development platform for roboticists, and Teq leads weeklong school programs geared for students of all ages in getting the robot to do interesting things.

"NAO represents the ability to bring error back into the classroom," said Dixon. "In the 1930s, educational reformer John Dewey said, 'Failure is instructive. The person who really thinks learns quite as much from his failures as from his successes.' Robots make it cool to make mistakes again."

Teq's program has students using the NAO robot's various sensors for navigation, face and voice recognition, and pre-programming specific movements. Despite having sensors and electronics that are about as sophisticated as you can get right now, Dixon says it's "amazingly simple at its base level."

Students are not writing lines and lines of intimidating computer code, but are instead building programs from a "block" language. This enables them to make the robot do useful things without the students' needing to learn super-specific computer syntax. These prewritten "blocks" can be modified and arranged so that NAO can dance, participate in a class' story time, and even help kids with autism interact with other people. But above all, learning elementary robotics teaches kids to think in terms of order and process.

"The robots provide instant feedback and the students don't get upset when something goes wrong, but they instead say, 'What happened?' This gives them the opportunity to make hundreds of mistakes in minutes," Dixon said.

Young er children are encouraged to think about what they'd like their robots to do. They often answer that it should make their bed or help their moms around the house.

Older kids will interact with the robots more directly, feeding it prewritten blocks of code to get it to do things.

Regardless of age, kids seem to love their robots.
