MIT Researchers Develop Wireless Trackpad For Your Thumbnail 19

itwbennett writes: Called NailO, the prototype trackpad is similar to the stick-on nails sometimes used as a fashion accessory. It attaches to the user's thumb and can be controlled by running a finger over its surface. The processor, battery, sensing chip and Bluetooth radio are included on a circuit board that sits under the capacitive trackpad. The two are connected via a small ribbon cable, which means the trackpad is not quite as thin as a stick-on nail, but reducing the size is one of the aims of the researchers.

Video Embedded Linux Takes to the Skies (Video) 26

This is an interview with Clay McClure. He makes his living designing 'custom Linux software solutions for technology start-ups in Atlanta and the San Francisco Bay area.' He also works on Embedded Linux for autonomous drones. Here's a link to slides from a talk he gave on exactly that topic: Flying Penguins - Embedded Linux Applications for autonomous UAVs, and that's far from all he has to say about making Linux-controlled drones. However, for some reason Timothy and Clay didn't talk about using drones for target practice. Perhaps they can discuss that another time.

NOTE: We urge you to read the transcript of this interview even if you prefer watching videos; it contains material we left out of the video due to sound problems.

The Crazy-Tiny Next Generation of Computers 104

An anonymous reader writes University of Michigan professors are about to release the design files for a one-cubic-millimeter computer, or mote. They have finally reached a goal set in 1997, when UC Berkeley professor Kristopher Pister coined the term "smart dust" and envisioned computers blanketing the Earth. Such motes are likely to play a key role in the much-ballyhooed Internet of Things. From the article: "When Prabal Dutta accidentally drops a computer, nothing breaks. There’s no crash. The only sound you might hear is a prolonged groan. That’s because these computers are just one cubic millimeter in size, and once they hit the floor, they’re gone. 'We just lose them,' Dutta says. 'It’s worse than jewelry.' To drive the point home, Dutta, an assistant professor of electrical engineering at the University of Michigan, emails me a photo of 50 of these computers. They barely fill a thimble halfway to its brim."

Researchers Design a Self-Powered Digital Camera 85

Jason Koebler writes: Researchers at Columbia University have designed a fully electric digital camera that powers itself using ambient light. Put in a well-lit room, it would work indefinitely. The camera's image sensor does double duty. It measures the light needed to make the photograph, and it also takes excess light and uses it to power a capacitor (it has no battery) that runs the camera (PDF). The research team says the technology can be used to create self-powered cameras that can live on the internet of things.

Samsung SSD On a Tiny M.2 Stick Is Capable of Read Speeds Over 2GB/sec 72

MojoKid writes: Samsung has just announced its new SM951-NVMe SSD, the industry's first NVMe SSD to employ an M.2 form-factor. Samsung says the new gumstick style drive is capable of sequential read and write speeds of 2,260 MB/sec and 1,600 MB/sec respectively. Comparable SATA-based M.2 SSDs typically can only push read/write speeds of 540 MB/sec and 500 MB/sec, while most standard PCIe versions muster just north of 1GB/sec. The Samsung SM951-NVMe's performance is actually very comparable to the Intel SSD 750 Series PCIe x4 card but should help kick notebook performance up a notch in this common platform configuration.

New Samsung SSD 840 EVO Read Performance Fix Coming Later This Month 72

An anonymous reader writes: The Samsung SSD 840 EVO read performance bug has been on the table for over six months now. Initially Samsung acknowledged the issue fairly quickly and provided a fix only a month after the news hit the mainstream tech media, but reports of read performance degradation surfaced again a few weeks after the fix had been released, making it clear that the first fix didn't solve the issue for all users. Two months ago Samsung announced that a new fix is in the works and last week Samsung sent out the new firmware along with Magician 4.6 for testing, which will be available to the public later this month.

Fifty Years of Moore's Law 101

HughPickens.com writes: IEEE is running a special report on "50 Years of Moore's Law" that considers "the gift that keeps on giving" from different points of view. Chris Mack begins by arguing that nothing about Moore's Law was inevitable. "Instead, it's a testament to hard work, human ingenuity, and the incentives of a free market. Moore's prediction may have started out as a fairly simple observation of a young industry. But over time it became an expectation and self-fulfilling prophecy—an ongoing act of creation by engineers and companies that saw the benefits of Moore's Law and did their best to keep it going, or else risk falling behind the competition."

Andrew "bunnie" Huang argues that Moore's Law is slowing and will someday stop, but the death of Moore's Law will spur innovation. "Someday in the foreseeable future, you will not be able to buy a better computer next year," writes Huang. "Under such a regime, you'll probably want to purchase things that are more nicely made to begin with. The idea of an "heirloom laptop" may sound preposterous today, but someday we may perceive our computers as cherished and useful looms to hand down to our children, much as some people today regard wristwatches or antique furniture."

Vaclav Smil writes about "Moore's Curse" and argues that there is a dark side to the revolution in electronics for it has had the unintended effect of raising expectations for technical progress. "We are assured that rapid progress will soon bring self-driving electric cars, hypersonic airplanes, individually tailored cancer cures, and instant three-dimensional printing of hearts and kidneys. We are even told it will pave the world's transition from fossil fuels to renewable energies," writes Smil. "But the doubling time for transistor density is no guide to technical progress generally. Modern life depends on many processes that improve rather slowly, not least the production of food and energy and the transportation of people and goods."

Finally, Cyrus Mody tackles the question: what kind of thing is Moore's Law? "Moore's Law is a human construct. As with legislation, though, most of us have little and only indirect say in its construction," writes Mody. "Everyone, both the producers and consumers of microelectronics, takes steps needed to maintain Moore's Law, yet everyone's experience is that they are subject to it."

Sharp Announces 4K Smartphone Display 152

An anonymous reader writes: Japanese electronics giant Sharp has announced production of 5.5" displays with 4K (3840 x 2160) resolution. They'll hit the market next year. The display will have a pixel density of 806 PPI. It's not known yet which smartphone makers will build devices with these screens. The displays cost significantly more than a more typical 1080p or 1440p display, so they'll probably only make it into high-end phones. On the other hand, this will help to drive down prices for lower-resolution displays, so it could indirectly benefit everybody.

Killer Robots In Plato's Cave 91

Lasrick writes Mark Gubrud writes about the fuzzy definitions used to differentiate autonomous lethal weapons from those classified as semi-autonomous: "After all, if the only criterion is that a human nominates the target, then even The Terminator...might qualify as semi-autonomous." Gubrud wants a ban against autonomous hunter-killer weapons like the Long-Range Anti-Ship Missile and the canceled Low-Cost Autonomous Attack System, and vague definitions surrounding autonomous and semi-autonomous weapons that will allow weapons that should be classified as autonomous but aren't. Existing definitions draw a "distinction without a difference" and "will not hold against the advance of technology." Gubrud prefers a definition that reduces autonomy to a simple operational fact, an approach he calls "autonomy without mystery." In the end, Gubrud writes, "Where one draws the line is less important than that it is drawn somewhere. If the international community can agree on this, then the remaining details become a matter of common interest and old-fashioned horse trading."

Transforming Robot Gets Stuck In Fukushima Nuclear Reactor 99

An anonymous reader writes with more bad news for the people still dealing with the Fukushima nuclear accident. "The ability to change shape hasn't saved a robot probe from getting stuck inside a crippled Japanese nuclear reactor. Tokyo Electric Power will likely leave the probe inside the reactor housing at the Fukushima Dai-ichi complex north of Tokyo after it stopped moving. On Friday, the utility sent a robot for the first time into the primary containment vessel (PCV) of reactor No. 1 at the plant, which was heavily damaged by the 2011 earthquake and tsunami in northern Japan. 'The robot got stuck at a point two-thirds of its way inside the PCV and we are investigating the cause,' a Tokyo Electric spokesman said via email. The machine became stuck on Friday after traveling to 14 of 18 planned checkpoints."

Report: Chinese Government Plans To Put 3D Printers In All Elementary Schools 99

InfiniteZero writes The Chinese government has a new plan to install a 3D printer in each of its approximately 400,000 elementary schools over the next two years. Education is probably one of the areas that will benefit the most from 3D printers in the long run. The problem though is getting the machines into the schools in the first place. With prices generally ranging from $400 to $3,000 for typical desktop 3D printers, they are not cheap, and with budgets within many school districts running dry, both in the United States and overseas, the unfortunate fact is that many schools simply can’t afford them, not to mention the materials and time it takes to train teachers to use them.

Ask Slashdot: Best Medium For Storing Data To Survive a Fire (or Other Disaster) 446

First time accepted submitter aka_bigred writes Every year as I file my taxes, I replicate my most important financial data (a couple GB of data) to store an offline copy in my fire-rated home safe. This gets me thinking about what the most reliable data media would be to keep in my fire-rated home safe.

CDs/DVDs/tapes could easily melt or warp rendering them useless, so I'm very hesitant to use them. I've seen more exotic solutions that let you print your digital data to paper an optically re-import it later should you ever need it, but it seems overly cumbersome and error prone should it be damaged or fire scorched. That leaves my best options being either a classic magnetic platter drive, or some sort of solid state storage, like SD cards, USB flash drives, or a small SSD. The problem is, I can't decide which would survive better if ever exposed to extreme temperatures, or water damage should my house burn down.

Most people would just suggest to store it in "the cloud", but I'm naturally averse to doing so because that means someone else is responsible for my data and I could lose it to hackers, the entity going out of business, etc. Once it leaves my home, I no longer fully control it, which is unacceptable. My thought being "they can't hack/steal what they can't physically access." What medium do other Slashdot users use to store their most important data (under say 5GB worth) in an at-home safe to protect it from fire?

Google Battles For Better Batteries 44

An anonymous reader writes: The Wall Street Journal reports that Google's X research lab has joined the quest for better batteries. The company has at least 20 projects that depend on batteries, from Google Glass to self-driving cars and drones. Thus, it makes sense for them to try developing new battery technology. "At Google, Dr. Bhardwaj's group is trying to advance current lithium-ion technology and the cutting-edge solid-state batteries for consumer devices. ... In a February presentation to an industry conference, Dr. Bhardwaj described how solid-state, thin-film batteries could be used in smartphones and other mobile devices that are thinner, bendable, wearable and even implantable in the human body. ... For the contact lens, the technology is safer because it doesn't use flammable electrolyte liquid, Dr. Bhardwaj's presentation explained."

LG Split Screen Software Compromises System Security 187

jones_supa writes: The Korean electronics company LG ships a split screen tool with their ultra wide displays. It allows users to slice the Windows desktop into multiple segments. However, installing the software seriously compromises security of the particular workstation. The developers required administrator access for the software, but apparently they hacked their way out. The installer silently disables User Account Control, and enables a policy to start all applications as Administrator. In the article there is also a video presentation of the setup procedure. It is safe to say that no one should be running this software in its current form.

Finding an Optimal Keyboard Layout For Swype 140

New submitter Analog24 writes: The QWERTY keyboard was not designed with modern touchscreen usage in mind, especially when it comes to swype texting. A recent study attempted to optimize the standard keyboard layout to minimize the number of swype errors. The result was a new layout that reduces the rate of swipe interpretation mistakes by 50.1% compared to the QWERTY keyboard.
