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"Read Replies (0)

Microsoft has released their latest earnings report
, and it's not as bleak as last week's news
might have you suspect. Quoting Forbes
: Microsoft reported $23.38 billion of revenue for the fourth quarter, up 17.5% from the same period last year. Net income, however, came in at $4.6 billion, down from last year and behind Wall Street analysts' consensus estimate, both about $5 billion. At 55 cents earnings per share were down 4 cents and a nickel short of the Street’s call. For the full year, revenue clocked in at $86.8 billion an 11.5% increase from a year earlier. Net income was $22.1 billion and earnings per share were $2.63.
They took a hit from finalizing the acquisition of Nokia's handset division (not unexpected). The cloud services side of the business appears to be growing, while traditional software sales have stagnated. The layoffs will cost Microsoft between $1.1 and $1.6 billion
over the first half of next year.Read Replies (0)

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."Read Replies (0)

An anonymous reader writes: Amazon's Fire Phone launches later this week, and the reviews have started to come in. The hardware: "There's nothing terribly special about the Fire Phone's hardware, but there's very little to turn you off either." "The nice-looking IPS display in the Fire Phone gets bright enough for outdoor viewing, and it has nice viewing angles—a necessity for a phone that's meant to be tilted around and looked at from every which way." "An indistinct slab of glass and plastic, the Fire Phone looks more like a minimalist prototype than a finished product."
Software: "Firefly can recognize lots of things, but it's incredibly, hilariously inconsistent." "Firefly is the one Fire Phone feature you'll want on any phone you're currently using. Let's hope that it gets enough developer support that it isn't just a link to Amazon's storefronts." "First, and to be absolutely clear, Dynamic Perspective will impress you the first time you see it, and Amazon is pretty good at showing it off. ... But if there's some cool, useful functionality to be had from super-aggressive, super-accurate face tracking, the Fire Phone doesn't have it." Conclusion: "Smartphones are for work, for life. They're not toys, they're tools. Amazon doesn't understand that, and the Fire Phone doesn't reflect it."Read Replies (0)

writes: The disastrous March 22 landslide that killed 43 people in the rural Washington state community of Oso involved the "remobilization" of a 2006 landslide on the same hillside, a new federally sponsored geological study concludes. The research indicates the landslide, the deadliest in U.S. history, happened in two major stages. The first stage remobilized the 2006 slide, including part of an adjacent forested slope from an ancient slide, and was made up largely or entirely of deposits from previous landslides. The first stage ultimately moved more than six-tenths of a mile across the north fork of the Stillaguamish River and caused nearly all the destruction in the Steelhead Haven neighborhood. The second stage started several minutes later and consisted of ancient landslide and glacial deposits. That material moved into the space vacated by the first stage and moved rapidly until it reached the trailing edge of the first stage, the study found. "Perhaps the most striking finding is that, while the Oso landslide was a rare geologic occurrence, it was not extraordinary," said Joseph Wartman, a University of Washington associate professor of civil and environmental engineering and a team leader for the study.Read Replies (0)

sends this quote from Ars:No company has lobbied more fiercely against network neutrality than Verizon, which filed the lawsuit that overturned the FCC's rules prohibiting ISPs from blocking and discriminating against Web content. But the absence of net neutrality rules isn't just good for Verizon—it's also good for the blind, deaf, and disabled, Verizon claims. That's what Verizon lobbyists said in talks with congressional staffers, according to a Mother Jones report last month. "Three Hill sources tell Mother Jones that Verizon lobbyists have cited the needs of blind, deaf, and disabled people to try to convince congressional staffers and their bosses to get on board with the fast lane idea," the report said. With "fast lanes," Web services—including those designed for the blind, deaf, and disabled—could be prioritized in exchange for payment. Now, advocacy groups for deaf people have filed comments with the FCC saying they don't agree with Verizon's position."Read Replies (0)

writes:The EFF has released an experimental router firmware designed make it easy to deploy open (password-less) access points in a secure manner. The EFF's firmware is based on the CeroWRT fork of OpenWRT, but appears to remove some of its more advanced routing features.
The EFF is asking for help to further develop the firmware. They want the open access point to co-exist on the same router as your typical private and secured access point. They want the owner to be able to share bandwidth, but with a cap, so guests don't degrade service for the owner. They're also looking to develop a network queueing, a minimalist web UI, and an auto-update mechanism. The EFF has also released the beta version of a plug-in called Privacy Badger

writes A presentation on a low-budget method to unmask users of a popular online privacy tool Tor will no longer go ahead at the Black Hat security conference early next month. The talk was nixed by the legal counsel with Carnegie Mellon's Software Engineering Institute after a finding that materials from researcher Alexander Volynkin were not approved for public release, according to a notice on the conference's website.
Tor project leader Roger Dingledine said, "I think I have a handle on what they did, and how to fix it. ... Based on our current plans, we'll be putting out a fix that relays can apply
that should close the particular bug they found. The bug is a nice bug, but it isn't the end of the world." Tor's developers were "informally" shown materials about the bug

An anonymous reader writes: Brianna Wu, leader of a game development studio, has an article exposing the constant harassment of women in the games industry. She says, "I'm not writing this piece to evoke your sympathy. I'm writing to share with you what prominent, successful women in the industry experience, in their own words." She goes through the individual stories of several women targeted by this vitriol, and tries to figure out why it happens. Quoting: "We live in a society that's sexist in ways it doesn't understand. One of the consequences is that men are extremely sensitive to being criticized by women. ... This is why women are socialized to carefully dance around these issues, disagreeing with men in an extremely gentle manner. Not because women are nicer creatures than men. But because our very survival can depend on it. ... Growing a thicker skin isn't the answer, nor is it a proper response. Listening, and making the industry safer for the existence of visible women is the best, and only, way forward."Read Replies (0)
