coop0030 writes "Open source hardware company Adafruit has announced a new tiny wearable electronics platform board called the Gemma. The Gemma is a tiny, 1-inch diameter and 4-mm thick package. It's powered by an Attiny85 and programmable with an Arduino IDE over USB. There are three available I/O pins, one of which is also an analog input and two of which can do PWM output. Gemma is currently wrapping up development, but should be available soon."

Zothecula writes "Given that most real-life superheroes don't have the budget of Tony Stark or Bruce Wayne, you would assume that their gadgetry wouldn't be quite on par with what we're used to seeing in the movies. German cyber weapons hobbyist Patrick Priebe, however, has built his own working laser gauntlet... just like the one made famous by a certain Iron Man."
kkleiner writes "No longer will they say, 'He's going to end up flipping burgers.' Now, robots are taking even these ignobly esteemed jobs. San Francisco based Momentum Machines makes a robot called the Alpha that can churn out 360 gourmet burgers per hour. The company plans on launching the first ever burger restaurant chain with a cook staff made entirely of robots. You think Americans are obese right now? Just wait."
mynamestolen writes "In order to read paper-based books many visually impaired people want to attach a webcam to a computer and attach the computer to a TV. Some Electronic Magnifiers are purpose-built to provide a similar solution. Different organisations around the world (such as in the UK) have help pages. But I have not been able to find a guide to set up my own system. So I'm asking Slashdot readers how to go about it. What is the best camera to use if I want to hold the camera in my hand and point it at book or magazine? What parameters should I adjust, either in the software or on the camera? Depth of view, refresh rates, contrast, color balance and resolution might be key problems. My system is Linux and getting drivers for a good camera might also be a problem."
Nerval's Lobster writes "For quite some time Mozilla has been working on Firefox OS, a lightweight mobile OS built in HTML5. Now it's whipped the curtain back from the first developer preview phones. The developer preview phones are unlocked, requiring the user insert their own SIM card. If those specs seem a little underpowered compared to other smartphones on the market, it's because Firefox OS is intended for lower-end smartphones; target markets include developing countries such as Brazil and China. (The first developer preview phones will be available in February.) The Firefox OS (once known as 'Boot to Gecko') is based on a handful of open APIs. The actual interface is highly reminiscent of Google Android and Apple iOS, with grids of icons linked to applications." The specs really aren't that bad; reader sfcrazy points out that they include the usual features baked into medium- and high-end phones these days: Wifi N, light and proximity sensors, and an accelerometer (though no mention of NFC).
Nerval's Lobster writes "Last week, Facebook announced Graph Search, a system for searching the social network's vast collection of users, photos, and 'Liked' interests. But how will Facebook power it? The Disaggregated Rack, which will separate compute, RAM, storage, and caching functions in order to remain flexible in the face of Graph Search's changing needs. By breaking up resources and scaling them independently of each other, Facebook can scale without needing to constantly open up new servers and upgrade new hardware."
Will the Open Compute Project’s Common Slot specification and Facebook’s Group Hug board commoditize the data center hardware market even further? Analyst opinions vary widely, indicating that time and additional development work may be necessary before any sort of consensus is reached. At the Open Compute Summit last week, Frank Frankovsky, director of hardware design and supply chain operations at Facebook, announced both the Open Slot specification and Facebook’s prototype Open Slot board, known as “Group Hug.” Group Hug’s premise is simple: disaggregate the CPU in a way that allows virtually any processor to be linked to the motherboard. This has never been done before with a CPU, which has traditionally required its own socket, its own chipset, and thus its own motherboard. Group Hug is designed to accommodate CPUs from AMD, Intel, and even ARM vendors such as Applied Micro and Calxeda.
Zothecula writes "Scientists based at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have set a new efficiency record for thin-film copper indium gallium (di)selenid (or CIGS) based solar cells on flexible polymer foils, reaching an efficiency of 20.4 percent. This is an increase from a previous record of 18.7 percent set by the team back in 2011."
Kim Dotcom's new "Mega" cloud service appears to be a hit. According to Dotcom over 1 million have signed up for their free 50 gigabytes of storage. Although that is about 1% of the Dropbox user base, it's not a bad start. From the article: "Mega quickly jumped up to around 100,000 users within an hour or so of the site's official launch. A few hours after that, Mega had ballooned up to approximately a quarter of a million users. Demand was great enough to knock Mega offline for a number of users attempting to either connect up or sign up for new accounts, and Mega's availability remains spotty as of this articles' writing."
hypnosec writes "Stephen Hawking's ability to communicate has been deteriorating over the years and as it stands, he is only able to communicate at the rate of 1 word per minute. Intel CTO Justin Rattner has revealed that they are working on an interface that will boost the scientist's speech to up to 10 words per minute. Beyond twitching his cheek, Hawking is also capable of other voluntary facial expressions which can be tapped to achieve faster communications with the help of a better character interface and a better word predictor."
hydrofix writes "The Wikimedia Foundation is preparing for the transition of its main technical operations to a new data center in Ashburn, Virginia. This is intended to improve the technical performance and reliability of all Wikimedia sites, including Wikipedia. The current target windows for the migration are January 22nd, 23rd and 24th, 2013, from 17:00 to 01:00 UTC. Since 2004, Wikimedia sites have been hosted in the main data center in Tampa, Florida, a location chosen for its proximity to Jimmy Wales at the time. In 2009, the Wikimedia Foundation's Technical Operations team started to look for other locations with better network connectivity and more clement weather. Located in the Washington, D.C. metropolitan area, Ashburn offers faster and more reliable connectivity than Tampa, and usually fewer hurricanes."
An anonymous reader writes "After months of hype riding the coattails of the MegaUpload controversy, Kim Dotcom's new cloud storage site, Mega, is finally going live. After being available to early adopters briefly, it's now open to the public with 50GB of free storage and end-to-end encryption. Several outlets have posted early hands-on reports for the service, including Ars Technica and The Next Web. In an interview, Dotcom spoke about how Mega's encryption scheme benefits both the users and the company: 'The Mega business plan will be a distributed model, with hundreds of companies large and small, around the world, hosting files. A hosting company can be huge or it can own just two or three servers Dotcom says—just as long as it's located outside the U.S. "Each file will be kept with at least two different hosters, [in] at least two different locations," said Dotcom. "That's a great added benefit for us because you can work with the smallest, most unreliable [hosting] companies. It doesn't matter because they can't do anything with that data." More than 1000 hosts answered a request for expressions of interest on the Mega home page. Dotcom says several hundred will be active partners within months.' On top of that, the way it's designed will protect Mega from legal problems: 'It's all about the plausible deniability. Mega doesn't know what you're uploading. ... Mega isn't so much securing your files for you as it is securing itself from your files. If Mega just takes down all the DMCAed links, it will have a 100 percent copyrighted material takedown record as far as its own knowledge is concerned. It literally can't know about cases that aren't actively pointed out to it, complete with file decryption keys.'"
New submitter Hesh writes "Ibex, the first cross-platform VR desktop of its kind, was previously released for Linux, and has finally been updated to work on Mac OS X Mountain Lion. Running at a silky smooth 60fps, it is nearing final release and awaiting delivery of the developer Oculus Rift kits for final integration testing. A Windows version may be released in time. The source can be found on bitbucket for the Linux version and iPhone orientation sensor client while the Mac source is to follow soon at the same location."
An anonymous reader writes "3D printing is on its way toward becoming ubiquitous. Of course, if you have such a printer and want to print something, you need raw materials — the plastic filament that's fed into the machine. It's also likely that while you're learning the ropes, you'll print a bunch of terrible attempts at objects, and end up having to throw them out. Now, Wired is reporting on a device aiming to solve both of those problems. Tyler McNaney's 'Filabot' will break down failed projects as well as many other plastic items from traditional manufacturers, turning them into a filament you can then feed through a 3D printer. 'So far the plastics that work are HDPE, LDPE, ABS, NYLON. More to come on the different types that work.' McNaney sees it as a 'closed-loop recycling system on your desk.' The Filabot's Kickstarter campaign succeeded easily in 2012, and now he and his team are getting ready to launch."
An anonymous reader writes "Wired reports on a research paper from Google employees about the future of authentication on the web. 'Along with many in the industry, we feel passwords and simple bearer tokens such as cookies are no longer sufficient to keep users safe,' the authors write. Their plan involves authenticating just once, to a single device, and then using that to unlock all of your other accounts. "We'd like your smartphone or smartcard-embedded finger ring to authorize a new computer via a tap on the computer, even in situations in which your phone might be without cellular connectivity." Recognizing that this isn't something they can accomplish on their own, they've gone ahead and created a device-based authentication protocol that is 'independent of Google, requires no special software to work — aside from a web browser that supports the login standard — and which prevents web sites from using this technology to track users.'"
