Lots Of People Really Want Slideout-Keyboard Phones: Where Are They? 46

Posted by timothy
from the could-be-anywhere-really dept.
Bennett Haselton writes: I can't stand switching from a slideout-keyboard phone to a touchscreen phone, and my own informal online survey found a slight majority of people who prefer slideout keyboards even more than I do. Why will no carrier make them available, at any price, except occasionally as the crummiest low-end phones in the store? Bennett's been asking around, of store managers and users, and arrives at even more perplexing questions. Read on, below.

Oracle Offers Custom Intel Chips and Unanticipated Costs 57

Posted by timothy
from the your-fries-come-with-lobster dept.
jfruh (300774) writes "For some time, Intel has been offering custom-tweaked chips to big customers. While most of the companies that have taken them up on this offer, like Facebook and eBay, put the chips into servers meant for internal use, Oracle will now be selling systems running on custom Xeons directly to end users. Those customers need to be careful about how they configure those systems, though: in the new Oracle 12c, the in-memory database option, which costs $23,000 per processor, is turned on by default."

Stanford Team Creates Stable Lithium Anode Using Honeycomb Film 83

Posted by timothy
from the high-voltage dept.
puddingebola (2036796) writes "A team at Stanford has created a stable Lithium anode battery using a carbon honeycomb film. The film is described as a nanosphere layer that allows for the expansion of Lithium during use, and is suitable as a barrier between anode and cathode. Use of a lithium anode improves the coulombic efficiency and could result in longer range batteries for cars." The linked article suggests that the 200-mile-range, $25,000 electric car is a more realistic concept with batteries made with this technology, though some people are more interested in super-capacity phone batteries.

The Oculus Rift DK2: In-Depth Review (and Comparison To DK1) 39

Posted by timothy
from the here-put-this-on-your-face dept.
Benz145 (1869518) writes "The hotly anticipated Oculus Rift DK2 has begun arriving at doorsteps. The DK2s enhancements include optical positional tracking and a higher resolution panel, up from 1280×800 to 1920×1080 (1080p) and moved to a pentile-matrix OLED panel for display duties. This means higher levels of resolvable detail and a much reduced screen door effect. The panel features low persistence of vision, a technology pioneered by Valve that aims to cut motion artefacts by only displaying the latest, most correct display information relative to the user's movements – as users of the DK1 will attest, its LCD panel was heavily prone to smearing, things are now much improved with the DK2."

A Router-Based Dev Board That Isn't a Router 52

Posted by timothy
from the hook-it-to-anything dept.
An anonymous reader writes with a link to an intriguing device highlighted at Hackaday (it's an Indiegogo project, too, if it excites you $90 worth, and seems well on its way to meeting its modest goal): The DPT Board is something that may be of interest to anyone looking to hack up a router for their own connected project or IoT implementation: hardware based on a fairly standard router, loaded up with OpenWRT, with a ton of I/O to connect to anything.

It's called the DPT Board, and it's basically an hugely improved version of the off-the-shelf routers you can pick up through the usual channels. On board are 20 GPIOs, USB host, 16MB Flash, 64MB RAM, two Ethernet ports, on-board 802.11n and a USB host port. This small system on board is pre-installed with OpenWRT, making it relatively easy to connect this small router-like device to LED strips, sensors, or whatever other project you have in mind.

Report: Nuclear Plants Should Focus On Risks Posed By External Events 110

Posted by timothy
from the it-might-be-this-knob-or-maybe-that-one dept.
mdsolar (1045926) writes "Engineers at American nuclear plants have been much better at calculating the risk of an internal problem that would lead to an accident than they have at figuring the probability and consequences of accidents caused by events outside a plant, a report released Thursday by the National Academy of Science said. Accidents that American reactors are designed to withstand, like a major pipe break, are "stylized" and do not reflect the bigger source of risk, which is external, according to the study. That conclusion is one of the major lessons from the Fukushima Daiichi nuclear accident in Japan in 2011, which began after an earthquake at sea caused a tsunami.

Greenpeace: Amazon Fire Burns More Coal and Gas Than It Should 280

Posted by timothy
from the not-enough-greenwashing dept.
Jason Koebler (3528235) writes "The biggest thing that sets the Amazon Fire Phone apart from its Android and Apple competitors probably isn't the clean interface or the unlimited photo storage—it's the dirty power behind it. When Fire users upload their photos and data to Amazon's cloud, they'll be creating a lot more pollution than iPhone owners, Greenpeace says. Apple has made a commitment to running its iCloud on 100 percent clean energy. Amazon, meanwhile, operates the dirtiest servers of any major tech giant that operates its own servers—only 15 percent of its energy comes from clean sources, which is about the default national average." Greenpeace's jaundiced eye is on Amazon more generally; the company's new phone is just an example. Maybe Amazon or some other provider could take a page from some local utilities and let users signal their own preferences with a (surcharged) "clean energy" option.

Household Robot Jibo Nets Over $1 Million On Indiegogo 61

Posted by timothy
from the one-meeeelion-dollars dept.
mikejuk (1801200) writes After seven days the Jibo project has over $1.1 million. What is surprising is that Jibo isn't a complex piece of hardware that will do the dishes and pick up clothes. It doesn't move around at all. It just sits and interacts with the family using a camera, microphones and a voice. It is a social robot, the speciality of the founder, MIT's, Cynthia Breazeal. The idea is that this robot will be your friend, take photos, remind you of appointments, order takeaway and tell the kids a story. If you watch the promo video then you can't help but think that this is all too polished and the real thing will fall flat on its face when delivered. If it does work then worry about the hundreds of kids needing psychiatric counselling — shades of Robbie in I, Robot. Even if it is hopelessly hyped — there is a development system and I want one. It is the early days of the home computer all over again.

muterobert (2927951) writes Paul James goes hands on with one of the first next-gen Oculus Rifts in the wild: "After much hacking (and some kind developer linkage) I stepped into a DK2 enabled version of Technolust and lost myself utterly! The stunning attention to detail, neon on black really lets the OLED panel shine here. In fact, this experience was the closest I think I've ever some to presence in virtual reality thus far. Leaning in to check the myriad retro objects, gawking at the lighting and just generally being blown away by the experience. This game was fabulous on the DK1, it's utterly compelling now."

"Magic Helmet" For F-35 Ready For Delivery 184

Posted by samzenpus
from the watch-your-six-and-stay-frosty dept.
Graculus writes with news that the so called "magic helmets" for the controversial F-35 are ready for action. This week, Lockheed Martin officially took delivery of a key part of the F-35 fighter's combat functionality—the pilot's helmet. The most expensive and complicated piece of headgear ever constructed, the F-35 Gen III Helmet Mounted Display System (HMDS) is one of the multipurpose fighter's most critical systems, and it's essential to delivering a fully combat-ready version of the fighter to the Marine Corps, the Navy, and the Air Force. But it almost didn't make the cut because of software problems and side effects akin to those affecting 3D virtual reality headsets.

Built by Rockwell Collins ESA Vision Systems International (a joint venture between Rockwell Collins and the Israeli defense company Elbit Systems), the HMDS goes way beyond previous augmented reality displays embedded in pilots' helmets. In addition to providing the navigational and targeting information typically shown in a combat aircraft's heads-up display, the HMDS also includes aspects of virtual reality, allowing a pilot to look through the plane. Using a collection of six high-definition video and infrared cameras on the fighter's exterior called the Distributed Aperture System (DAS), the display extends vision a full 360 degrees around the aircraft from within the cockpit. The helmet is also equipped with night vision capabilities via an infrared sensor that projects imagery inside the facemask

from the keyboard-as-cool-as-a-woodie-station-wagon dept.
Plastic, plastic everywhere! Except on most surfaces of the Keyboardio ergonomic keyboard, which started as a 'scratch his itch' project by Jesse Vincent. According to his blurb on the Keyboardio site, Jesse 'has spent the last 20 years writing software like Request Tracker, K-9 Mail, and Perl. He types... a lot. He tried all the keyboards before finally making his own.'

His objective was to make a keyboard he really liked. And he apparently has. This video was shot in June, and Jesse already has a new model prototype under way that Tim Lord says is a notable improvement on the June version he already liked. || Note that the Keyboardio is hackable and open source, so if you think you can improve it, go right ahead.

from the protect-ya-neck dept.
First time accepted submitter Carly Page writes When asked for its response to Edward Snowden's claims that "Dropbox is hostile to privacy", Dropbox told The INQUIRER that users concerned about privacy should add their own encryption. The firm warned however that if users do, not all of the service's features will work. Head of Product at Dropbox for Business Ilya Fushman says: "We have data encrypted on our servers. We think of encryption beyond that as a users choice. If you look at our third-party developer ecosystem you'll find many client-side encryption apps....It's hard to do things like rich document rendering if they're client-side encrypted. Search is also difficult, we can't index the content of files. Finally, we need users to understand that if they use client-side encryption and lose the password, we can't then help them recover those files."

Intel Launches Self-Encrypting SSD 91

Posted by Soulskill
from the masochistic-storage-devices dept.
MojoKid writes: Intel just launched their new SSD 2500 Pro series solid state drive, the follow-up to last year's SSD 1500 Pro series, which targets corporate and small-business clients. The drive shares much of its DNA with some of Intel's consumer-class drives, but the Pro series cranks things up a few notches with support for advanced security and management features, low power states, and an extended management toolset. In terms of performance, the Intel SSD 2500 Pro isn't class-leading in light of many enthusiast-class drives but it's no slouch either. Intel differentiates the 2500 Pro series by adding support for vPro remote-management and hardware-based self-encryption. The 2500 Pro series supports TCG (Trusted Computing Group) Opal 2.0 features and is Microsoft eDrive capable as well. Intel also offers an administration tool for easy management of the drive. With the Intel administration tool, users can reset the PSID (physical presence security ID), though the contents of the drive will be wiped. Sequential reads are rated at up to 540MB/s, sequential writes at up to 480MB/s, with 45K – 80K random read / write IOps.

Researchers Print Electronic Memory On Paper 78

Posted by Unknown Lamer
from the pen-and-paper-computing dept.
MTorrice (2611475) writes Electronics printed on paper promise to be cheap, flexible, and recyclable, and could lead to applications such as smart labels on foods and pharmaceuticals or as wearable medical sensors. Many engineers have managed to print transistors and solar cells on paper, but one key component of a smart device has been missing—memory. Now a group of researchers has developed a method that uses ink-jet technology to print resistive random access memory on an ordinary letter sized piece of paper. The memory is robust: Engineers could bend the device 1,000 times without any loss of performance. The memory is not yet very dense, but could be: "Each silver dot they printed was approximately 50 microns across and separated from its neighbor by 25 microns, so each bit of memory is 100 microns on a side. At that size, a standard 8.5- by 11-inch piece of paper can hold 1 MB of memory. Der-Hsien Lien, the paper's lead author, says existing ultrafine ink-jet technology can produce dots less than 1 micron across, which would allow the same piece of paper to hold 1 gigabyte. Reading and writing the bits takes 100 to 200 microseconds"

Robot With Broken Leg Learns To Walk Again In Under 2 Minutes 69

Posted by Unknown Lamer
from the unstoppable-robot-overlords dept.
KentuckyFC (1144503) writes When animals lose a limb, they learn to hobble remarkably quickly. And yet when robots damage a leg, they become completely incapacitated. That now looks set to the change thanks to a group of robotics engineers who have worked out how to dramatically accelerate the process of learning to walk again when a limb has become damaged. They've tested it on a hexapod robot which finds an efficient new gait in under two minutes (with video), and often faster, when a leg becomes damaged. The problem for robots is that the parameter space of potential gaits is vast. For a robot with six legs and 18 motors, the task of finding an efficient new gait boils down to a search through 36-dimensional space. That's why it usually takes so long. The new approach gets around this by doing much of this calculation in advance, before the robot gets injured. The solutions are then ordered according to the amount of time each leg remains in contact with the ground. That reduces the dimension of the problem from 36 to 6 and so makes it much easier for the robot to search. When a leg becomes damaged, the robot selects new gaits from those that minimize contact with the ground for the damaged limb. It compares several and then chooses the fastest. Voila! The resulting gaits are often innovative, for example, with the robot moving by springing forward. The new approach even found a solution should all the legs become damaged. In that case, the robot flips onto its back and inches forward on its "shoulders."

As odd as it sounds, this minor yet demonstrable harm is what will allow their lawsuit to go forward. A federal judge ruled that the claim "requires a heavily and inherently fact-bound inquiry." That means there's a good chance we're about to get a look into the ins and outs of Google's advertising backbone: what information is shared with whom, and when.

Google Offers a Million Bucks For a Better Inverter 260

An anonymous reader writes: With the Little Box Challenge, Google (and IEEE, and a few other sponsors like Cree and Rohm) is offering a $1 million prize to the team which can "design and build a kW-scale power inverter with the highest power density (at least 50 Watts per cubic inch)." Going from cooler-sized to tablet sized, they say, would make a whole lot of things better, and the prize is reserved for the best performing entrant. "Our testing philosophy is to not look inside the box. You provide us with a box that has 5 wires coming out of it: two DC inputs, two AC outputs and grounding connection and we only monitor what goes into and comes out of those wires, along with the temperature of the outside of your box, over the course of 100 hours of testing. The inverter will be operating in an islanded more—that is, not tied or synced to an external grid. The loads will be dynamically changing throughout the course of the testing, similar to what you may expect to see in a residential setting." The application must be filled out in English, but any serious applicants can sign up "regardless of approach suggested or team background." Registration runs through September.

rtoz writes Researchers from Seoul National University have designed a robotic wheel based on the origami "magic ball pattern," which is a traditional technique used to create folded paper spheres. This robotic wheel can change its radius to create larger wheels to climb over things, and shrink back to a smaller size to squeeze under obstacles. The diameter of the wheels changes automatically to enable the robot to either be strong or speedy. The scientists think their innovation could one day be used for interplanetary rovers as the wheel can be folded up and "inflate" itself.

Linux Needs Resource Management For Complex Workloads 161

storagedude writes: Resource management and allocation for complex workloads has been a need for some time in open systems, but no one has ever followed through on making open systems look and behave like an IBM mainframe, writes Henry Newman at Enterprise Storage Forum. Throwing more hardware at the problem is a costly solution that won't work forever, he notes.

Newman writes: "With next-generation technology like non-volatile memories and PCIe SSDs, there are going to be more resources in addition to the CPU that need to be scheduled to make sure everything fits in memory and does not overflow. I think the time has come for Linux – and likely other operating systems – to develop a more robust framework that can address the needs of future hardware and meet the requirements for scheduling resources. This framework is not going to be easy to develop, but it is needed by everything from databases and MapReduce to simple web queries."
