davecb writes "Paul E. McKenney, one of the Linux RCU implementors, addresses the problem of synchronization using structured deferral on, what else, Mr Schrödinger's famous cat. Courtesy of deferral/procrastination, the cat can be both alive and dead at the same time. 'In this example, Schrödinger would like to construct an in-memory database to keep track of the animals in his zoo. Births would of course result in insertions into this database, while deaths would result in deletions. The database is also queried by those interested in the health and welfare of Schrödinger's animals. Schrödinger has numerous short-lived animals such as mice, resulting in high update rates. In addition, there is a surprising level of interest in the health of Schrödinger's cat, so much so that Schrödinger sometimes wonders whether his mice are responsible for most of these queries. Regardless of their source, the database must handle the large volume of cat-related queries without suffering from excessive levels of contention. Both accesses and updates are typically quite short, involving accessing or mutating an in-memory data structure, and therefore synchronization overhead cannot be ignored.'"
An anonymous reader sends news of a study which found that "two out of five medical students have an unconscious bias against obese people." The study, published in the Journal of Academic Medicine (abstract) examined med students from many different cultural and geographical backgrounds. "The researchers used a computer program called the Weight Implicit Association Test (IAT) to measures students’ unconscious preferences for 'fat' or 'thin' individuals. Students also answered a survey assessing their conscious weight-related preferences. The authors determined if the students were aware of their bias by seeing if their IAT results matched their stated preferences. Overall, 39 percent of medical students had a moderate to strong unconscious anti-fat bias as compared to 17 percent who had a moderate to strong anti-thin bias. Less than 25 percent of students were aware of their biases. 'Because anti-fat stigma is so prevalent and a significant barrier to the treatment of obesity, teaching medical students to recognize and mitigate this bias is crucial to improving the care for the two-thirds of American adults who are now overweight or obese,' Miller said. 'Medical schools should address weight bias as part of a comprehensive obesity curriculum.'"
An anonymous reader writes "Twilio's Jon Gottfried has written an article about the lessons he's learned after six months of developing software for Google Glass. He has some insightful points: 'I expected it to be very similar to building mobile applications for Android. In fact, I began learning to build Android applications in preparation. My efforts were for naught, because the Mirror API is a RESTful web service. This means that developing applications for Glass is actually more similar to building a website than it is to building an Android application.' He also talks about how this fits in with the future of technology: 'I would argue that Google took the only option available to them. The only truly scalable products of the future will be developer platforms. Facebook, Twitter, Twilio, Google, Apple, Microsoft, Arduino – all of these products have been successful in large part by embracing and empowering their developer communities. No company is omniscient enough to imagine every potential use of their products. This gives developers an immense amount of power to define the success or failure of an entire product line.'"
An anonymous reader writes "A very recent paper in the prestigious biology journal Cell — 'Human Embryonic Stem Cells Derived by Somatic Cell Nuclear Transfer' (openly accessible) — reports the novel creation of human embryonic stem cells from somatic nuclei. It has received massive media coverage and is surely penciled in as a strong candidate for scientific publication of the year. It does however have several examples of image reuse that have been pointed out by a submission on PubPeer. In the paper, it is recorded that the journal Cell accepted this paper just 4 days after submission. Perhaps, under the circumstances, the pre-publication peer review had to be a little hasty? At least at PubPeer, while conducting post publication review, we can take as long as necessary to make up for that lost time. 'In 2004 scientists led by Woo Suk Hwang of Seoul National University claimed to have produced human embryonic stem cells through the same technique used by the Oregon team. Their paper, published in Science, turned out to contain fabricated data. That came to light when scientists figured out that some of the images in the paper were copied or manipulated.''"
An anonymous reader writes "As we in the U.S. settle in for Memorial Day weekend, this article points out how our cultural addiction to technology is making it less of a vacation than it used to be. 'The average smartphone user checks his or her device 150 times per day, or about once every six minutes. Meanwhile, government data from 2011 says 35 percent of us work on weekends, and those who do average five hours of labor, often without compensation — or even a thank you. The other 65 percent were probably too busy to answer surveyors' questions.' Even for those of us who don't have any work to do over the weekend, we'll probably end up reading all of our work-related emails as they roll in, and take time out of our day to think about what's going on — to the detriment of our weekend activities: 'A study at the University of California, San Francisco, found that new experiences fail to become long-term memories unless brains have downtime for review.' I imagine it's even worse for your average Slashdotter, who's likely plugged in to more technology at home and at work. How can we make our employers understand that downtime needs to remain downtime? 'It took labor unions 100 years to fight for nights and weekends off, some say, while smartphones took them away in about three years.'"
New submitter home-electro.com writes "In the era of total CAD and CAM, is it even possible to come up with a fundamentally flawed design ? Turns out, yes. This a fascinating engineering SNAFU. Spain's newly built submarine is 100 tons too heavy, which means it is unable to float. 'Unfortunately for the Spainards, Quartz reports that they have already sunk the equivalent of $680 million into the Isaac Peral, and a total of $3 billion into the entire quartet of S-80 class submarines. If Spain hopes to salvage its submarines, it must either find some weight that can be trimmed from the current design or lengthen the ship to accommodate the excess weight, The Local notes. Though the latter option is more feasible, it is expected to cost Spain an extra $9.7 million per meter.'"
An anonymous reader writes "Now that both Sony and Microsoft have announced their next-gen consoles, and we've gotten solid information about their hardware, technology, and features, Eurogamer asks whether Nintendo's struggling Wii U will be able to hold its own once the new competition arrives. 'Wii U has tanked — there's no other way to put it — with even the release of traditional big-hitters like Dragon Quest 10 failing to make a dent in the Japanese market. If you believe certain analysts, April saw things getting even worse in the U.S. with the Wii U shifting under 40,000 units, easily outsold by the 360 and PS3 — and, even more embarrassingly, the Wii.' If the Wii U doesn't see a miraculous turnaround, Nintendo may be left with the difficult choice of whether to port its software to competing consoles. It'll also serve as a bellwether to see if the big gamer complaint about the new Sony and Microsoft consoles — that they're only partly about games — is honest. 'At a time when the goal of its competitors is to own the living room, the extent of Nintendo's ambition is simply to be in it — a dedicated games console, and no more.'"
00_NOP writes "'Universal Credit' — the plan to consolidate all Britain's welfare payments into one — is the world's biggest 'agile' software development project. It is now close to collapse, the British government admitted yesterday. The failure, if and when it comes, could cost billions and have dire social consequences. 'Some steps have been taken to try to rescue the project. The back end – the benefits calculation – has reportedly been shifted to a "waterfall" development process – which offers some assurances that the government at least takes its fiduciary duties seriously as it should mean no code will be deployed that has not been finished. The front end – the bit used by humans – is still meant to be “agile” – which makes some sense, but where is the testing? Agile is supposed to be about openness between developer and client and we – the taxpayers – are the clients: why can’t we see what our money is paying for?'"
An anonymous reader writes "Google has sent letters to app developers registered in Argentina saying they won't be able to accept payments on developers' behalf after June 27th. 'The change applies to both paid apps and apps that use in-app purchases. The move appears to be related to new, restrictive regulations the Argentine government has imposed on currency exchanges.' According to the Telegraph, 'The new regulations required anyone wanting to change Argentine pesos into another currency to submit an online request for permission to AFIP, the Argentine equivalent of HM Revenue & Customs. To submit the request, however, you first needed to get a PIN from AFIP, either online or in person. Having finally obtained your number, submitted your online request and printed out your permission slip, you could then present it at the bank or official cambio and buy your dollars. Well, that was the theory. In practice, the result was chaos. ... damming the flood has come at a huge cost to the economy, especially since the currency restrictions were coupled with another set of regulations that effectively imposed a near-total ban on any imported goods.'"

An anonymous reader writes "When it comes to spotting malware, signature-based detection, heuristics and cloud-based recognition and information sharing used by many antivirus solutions today work well up a certain point, but the polymorphic malware still gives them a run for their money. At the annual AusCert conference held this week in Australia a doctorate candidate from Deakin University in Melbourne has presented the result of his research and work that just might be the solution to this problem. Security researcher Silvio Cesare had noticed that malware code consists of small "structures" that remain the same even after moderate changes to its code. He created Simseer, a free online service that performs automated analysis on submitted malware samples and tells and shows you just how similar they are to other submitted specimens. It scores the similarity between malware (any kind of software, really), and it charts the results and visualizes program relationships as an evolutionary tree."
An anonymous reader writes "While everyone was glued to the Xbox One announcement, Nvidia GeForce GTX 780 launch, and Intel's pre-Haswell frenzy, it seems that AMD's launch was overlooked. On Wednesday, AMD launched its latest line of mobile APUs, codenamed Temash, Kabini, and Richland. Temash is targeted towards smaller touchscreen-based devices such as tablets and the various Windows 8 hybrid devices, and comes in dual-core A4 and A6 flavors. Kabini chips are intended for the low-end notebook market, and come in quad-core A4 and A6 models along with a dual-core E2. Richland includes quad-core A8 and A10 models, and is meant for higher-end notebooks — MSI is already on-board for the A10-5750M in their GX series of gaming notebooks. All three new APUs feature AMD HD 8000-series graphics. Tom's Hardware got a prototype notebook featuring the new quad-core A4-5000 with Radeon HD 8300 graphics, and benchmarked it versus a Pentium B960-based Acer Aspire V3 and a Core-i3-based HP Pavillion Sleekbook 15. While Kabini proves more efficient, and features more powerful graphics than the Pentium, it comes up short in CPU-heavy tasks. What's more, the Core-i3 matches the A4-5000 in power efficiency while its HD 4000 graphics completely outpace the APU."
An anonymous reader writes with this excerpt from PC Mag's SecurityWatch: "We've pointed out some problems with Twitter's new two-factor authentication. For example, since just one phone number can be associated with an account, Twitter's two-factor authentication won't work for organizations like the Associated Press, The Onion, or The Guardian. They were hacked; they could still be hacked again in the same way. However, security experts indicate that the problem is worse than that, a lot worse."

DeviceGuru writes "BeagleBoard.org has begun shipping its faster, cheaper BeagleBone Black SBC with a new Linux 3.8 kernel, supporting Device Tree technology for more streamlined ARM development. The $45 BeagleBone Black runs Linux or Android on a 1GHz TI Sitara AM3359 SOC, doubles the RAM to 512MB of its predecessor, and adds a micro-HDMI port. The updated kernel gives the BeagleBone Black access to a new Direct Rendering Manager (DRM) display driver architecture, as well as full support for the Device Tree data structure introduced to streamline ARM development in Linux 3.7. The project was hesitant to move up to such a recent kernel, but decided it was time to bite the bullet and support the Device Tree. By doing the hard work of switching to Device Tree now, BeagleBoard.org and its developer community can save a lot of configuration and maintenance headaches down the line, says BeagleBoard.org co-founder Jason Kridner. Fortunately, a modified 3.2 kernel 'coming soon' should provide the necessary bridge from the old cape driver architecture to the new one."

Earlier this year we discussed a petition on the White House's 'We The People' site asking the administration to adopt the metric system as the standard system of measurement in the U.S. Today, the administration issued a disappointing response. Simply put: they're not going to do anything about it. They frame their response as a matter of preserving a citizen's choice to adopt whatever measurement system he wants. Quoting Patrick D. Gallagher of the National Institute of Standards and Technology: "... contrary to what many people may think, the U.S. uses the metric system now to define all basic units used in commerce and trade. At the same time, if the metric system and U.S. customary system are languages of measurement, then the United States is truly a bilingual nation. ... Ultimately, the use of metric in this country is a choice and we would encourage Americans to continue to make the best choice for themselves and for the purpose at hand and to continue to learn how to move seamlessly between both systems. In our voluntary system, it is the consumers who have the power to make this choice. So if you like, "speak" metric at home by setting your digital scales to kilograms and your thermometers to Celsius. Cook in metric with liters and grams and set your GPS to kilometers. ... So choose to live your life in metric if you want, and thank you for signing on."
sciencehabit writes "Physicists have, for the first time, been able to image the quantum workings of electrons in hydrogen atoms, an advance that could open the door to a deeper understanding of the quantum world (abstract). Building on a 1981 proposal by three Russian theorists and more recent work that brought that proposal into the realm of possibility, the team first fired two lasers at hydrogen atoms inside a chamber, kicking off electrons at speeds and directions that depended on their underlying wave functions. A strong electric field inside the chamber guided the electrons to positions on a planar detector that depended on their initial velocities rather than on their initial positions. So the distribution of electrons striking the detector matched the wave function the electrons had at the moment they left their hydrogen nuclei behind. There may be practical applications in the future—a commentary accompanying the paper suggests that the method could aid in the development of technologies such as molecular wires, atom-thick conductors that could help shrink electronic devices—but that their result concerns 'extremely fundamental' physics that might be just as valuable for developing quantum intuition in the next generation of physicists."
New submitter kwyjibo87 writes "The World Health Organization (WHO) publicly expressed dismay yesterday concerning news that intellectual property claims were hindering research on a deadly new emerging virus. Novel coronavirus (nCoV), a member of the same viral genus as the causative agent of SARS, has claimed the lives of 22 people (out of 44 reported infected) and left both researchers and health officials scrambling to develop effective diagnostic tests in addition to possible medications and vaccines against nCoV. Now, however, claims of intellectual property on the new virus are hindering research on nCoV according to the WHO, delaying advancements on tools to prevent further spread of the infection. Stories of intellectual property rights in science hindering advancements in research, particularly in clinical applications, are nothing new; the U.S. Supreme Court recently heard arguments on the validity of patents on the BRCA1/2 genes and has yet to issue a decision. The issue of sharing scientific information in order to promote faster research on emerging pathogens is not limited to intellectual property — a recent article in the journal Nature highlighted a case where Chinese researchers risked having their research scooped after uploading viral sequences to a public database designed aid global scientific collaboration."
