First time accepted submitter vigna writes "The Laboratory for Web Algorithmics of the Università degli studi di Milano together with the Data and Web Science Group of the University of Mannheim have put together the first entirely open ranking of more than 100 million sites of the Web. The ranking is based on classic and easily explainable centrality measures applied to a host graph, and it is entirely open — all data and all software used is publicly available. Just in case you wonder, the number one site is YouTube, the second Wikipedia, and the third Twitter." They are using the Common Crawl data (first released in November 2011). Pages are ranked using harmonic centrality with raw Indegree centrality, Katz's index, and PageRank provided for comparison. More information about the web graph is available in a pre-print paper that will be presented at the World Wide Web Conference in April.

Daniel_Stuckey writes "A business park in North Korea will soon have (limited) access to the Internet, according to news reports. The Register wrote that an industrial park in the Kaesong Industrial Region will house Internet-connected PCs by the first half of this year. The Daily NK explained that the first step to connectivity will be an Internet cafe with 20 computers but afterward company offices will also be connected. They quoted a spokesperson from the Ministry of Unification — a department of the South Korean government that works on unifying the two Koreas — as saying, 'We are planning to launch the basic level of Internet services at the Kaesong Industrial Complex starting in the first half of this year,' and adding, 'Officials and employees in the North's border city will be able to use most of the online services now available in South Korea.'"

alphadogg writes "The exclusive relationship of ICANN with the U.S. must end, said the European Union's digital agenda chief on Wednesday. California-based ICANN is responsible for the assignment of top-level domains and has a long-standing operating agreement with the U.S. However, following the revelations by Edward Snowden of widespread surveillance of the Internet by the National Security Agency, many countries have questioned the arrangement. The historical relationship, noted in ICANN's Affirmation of Commitments, is outdated and the governance of the Internet must become more global, said the E.U. Digital Agenda Commissioner Neelie Kroes. Kroes was presenting the European Commission's new policy on Internet governance, which rejects any United Nations or governmental takeover of Internet governance and calls for a move to globalize ICANN."

Hugh Pickens DOT Com writes "Discovery News reports that the death cap mushroom is now an invasive species on every continent except Antarctica. It is spreading along the East and West Coasts of the U.S. and appears to be moving south into Mexico. 'When someone eats Amanita phalloides, she typically won't experience symptoms for at least six and sometimes as many as 24 hours,' says Cat Adams. 'Eventually she'll suffer from abdominal cramps, vomiting, and severely dehydrating diarrhea. This delay means her symptoms might not be associated with mushrooms, and she may be diagnosed with a more benign illness like stomach flu. To make matters worse, if the patient is somewhat hydrated, her symptoms may lessen and she will enter the so-called honeymoon phase.' Without proper, prompt treatment, the victim can experience rapid organ failure, coma, and death. But good news is on the way. S. Todd Mitchell of Dominican Hospital in Santa Cruz, California has treated more than 60 patients with a drug derived from milk thistle. The patients who have started the drug on time (within 96 hours of ingesting the mushroom) and who have still had kidney function intact have all survived. 'When administered intravenously, the compound sits on and blocks the receptors that bring amatoxin into the liver, thus corralling the amatoxins into the blood stream so the kidneys can expel them faster,' says Adams. Still, Mitchell cautions against the 'regular look"'of deadly mushrooms. 'They smell very good and when they're cooked, many patients have described them as the most delicious mushrooms they've ever eaten.'"

jfbilodeau sends word of a massive new trove of fossils located in Canada, which scientists say will rival the acclaimed Burgess Shale fossil bed. The rock formation inside which both fossil sites were found is roughly 505 million years old (abstract). The fossils provide insight into the Cambrian explosion, a time that brought the rapid appearance and diversification of many animal forms. "In just two weeks, the research team collected more than 3,000 fossils representing 55 species. Fifteen of these species are new to science." Paleontologist Jean-Bernard Caron said, "The rate at which we are finding animals — many of which are new — is astonishing, and there is a high possibility that we'll eventually find more species here than at the original Yoho National Park site, and potentially more than from anywhere else in the world." The fossils at the new site are about 100,000 years younger and are better preserved than those at the renowned Burgess shale site.

This site's "Your Rights Online" section, sadly, has never suffered for material. The revelations we've seen over the last year-and-change, though, of widespread spying on U.S. citizens, government spying in the E.U. on international conferences, the UK's use of malware against citizens, and the use of modern technology to oppress government protesters in the middle east and elsewhere shows how persistent it is. It's been a banner year on that front, and the banner says "You are being spied on, online and off." A broad coalition of organizations is calling today "The Day We Fight Back" against the growing culture of heads-they-win, tails-you-lose surveillance, but all involved know this is not a one-day struggle. (Read more, below.) THREE REASONS TO HATE MASS SURVEILLANCE:

1) Because the Internet is nearly everywhere, it means the spying it makes possible has spread to match its footprint. 30 years ago, "on the internet" really was novel, because the public Internet simply wasn't. There were a few big military and academic sites around the world, and the concepts that make today's internet work were already embodied in running systems, but there was little reason for individuals to care about privacy invasion, or having their systems crippled by government malware, because their systems and their privacy weren't at issue. There wasn't a World Wide Web as a portal to nearly every resource online, no "Cloud," and no Blue Coat. Now, not only can individuals get on the internet, but the meaning of that phrase has moved, fast, over the last decade: now, getting on the internet is just a fact of modern life, a banal, automated background fact of the way we stay in touch with friends, deal with bills, find entertainment, get directions, and work. Online surveillance of all the signals we emit and receive (over home internet links, over cellular networks, on landline telephones, even on postcards) might be minimized and waved away as the collection of "mere" metadata, but in reality, if you're reading these words online, and even if you're doing your best to read them anonymously, it means you've almost certainly got a collection of data about you online already.

2) Because "online surveillance" is a slippery slope, and it will only get slipperier. Remember the Clipper chip's hardware-based encryption escrow scheme? Who and how often you email, chat with online, or call on the phone is the tip of the iceberg. Robert Bork didn't like having his video watching habits spied on, and that was before Netflix and competitors made the sorting and stacking of movie-watching habits not only possible but an never-ending exercise in deep data analysis. Maybe you don't care in particular about what the NSA, FBI, or anyone else thinks of your taste in entertainment, but you might prefer them to stay out not only of the information revealed by your current online activity, but also out of whatever things are revealed by future developments. Right now, a relatively small part of the online population uses crypto-currency like Bitcoin; a decade from now, it seems likely to be even more widespread than Netflix is today. Do you want your transactions to be public record, or even public-servant record? Beyond that, the era of ubiquitous, automated surveillance doesn't need you to mail an angry letter, or declare allegiance to an unpopular cause online: Just walking around means sooner rather than later you're likely to be captured on camera.

Access to your medical records almost certainly will be online, too, even more than it already is. Online and offline lives will only get blurrier: Your GPS (and increasingly, that means your phone, too) knows where you've been, and your should-be-private Google Maps page knows where you might have considered going. (Couple that with the cavalier attitude that dominates rules about data that you carry in your phone, laptop or USB data sticks, if you cross, or even come near, the U.S. border.) Think about the meta-data (or what the government might characterize that way) that your reading and viewing habits, your prescription medicine needs, your airline tickets, and your Amazon wishlist could reveal, and whether you'd want everyone's digital dossier to be up for ad-hoc scrutiny in 10 years any more than it already is. You don't want the equivalent of the TSA viewing rooms (for your own good, of course) attached to every stream of online communication.

3) Because you're paying for it. How much you're paying is hard to say, because of black budgets, overlapping programs, and the sheer number of systems that are or could be used to make widespread surveillance the new normal, but the mystery price tag starts out high. If you're an American, or an EU citizen, at least you can be grateful that you're likely only being spied on, rather than actively harmed in other ways; in other countries, the outcome can be far grimmer. How much do you want to pay to build an infrastructure for constantly surveilling yourself, your friends, and your family? Especially one that fails so miserably at even its stated aims?

THREE WAYS TO FIGHT IT:

The good news is, while you can't stop the entire octopus, you're not required to be a full-time victim of online surveillance or the offline surveillance that it seems to normalize. Instead, you can take some simple steps that at least fog the glass a bit. Readers will no doubt suggest better technologies and practices, but here's a short list to start with:

1) Encryption, more often and in more contexts. Encrypted hard drives are now easy to buy off the shelf, or to implement with software per-user. Use encryption when it makes sense, for documents, emails, file systems, or browsing; the more you do, the more normal this becomes — if it's perfectly normal to carry data encrypted, no matter how innocuous, it's hard for merely possessing encrypted data to be vilified. TrueCrypt might not be impregnable, but neither are the opaque envelopes you might put in a physical mailbox: making it harder to spy on you even in small ways beats indifference. Good news: not every layer of security takes much effort for you to take advantage of: Mozilla's move to HTTPS Everywhere is an example, as is the option that many OSes are embracing to offer the user full-disk or per-directory encryption.

2) Avoid standing in front of the biggest targets. If you don't yet, use an operating system like Linux or one of the modern BSDs, at least part of the time. The SCADA vulnerabilities exploited to cripple a key part of Iran's nuclear program exploited a well-known hole in a widespread operating system, and the same can be said of many attacks blandly characterized as "Advanced Persistent Threats." Even a cheap, adjunct laptop running an up-to-date Linux or OpenBSD could make you safer for some tasks online; cheaper yet, you can run an entire Linux system from a USB drive, and yank it when you're through. That doesn't stop a mid-stream listener (which is a very hard problem), but a compartmentalized system like that means you can do your online banking or anything else and be less vulnerable to common malware. (Besides, it's fun!)

3) Tell companies, politicians (for instance, by voting for or against), and the people around you, that you object to being spied on. You can't prevent malicious individuals, governments, (or Google, or Yelp, or your Facebook friends) from looking at some of the data that you emit; you might feel perfectly satisfied with lots of the transactions you take part in freely. But you can minimize the worst consequences by being mindful of what you do or don't mind putting out there, and spreading the word when you find abuses of trust that compromise your privacy.

Online spying didn't pop into existence with Edward Snowden's revelations about mass data gathering by the NSA on U.S. citizens. For Americans, having our communications tapped by government agents (even if by a government that has remained far more benign than have many others) extends as long as the history of the country; likewise for Europeans and others all over the world. It's much easier, now, though, for those agents to put an ear to your wall or an eye on your correspondence than it's ever been before. For those in many countries, taking practical steps to reduce your exposure is a sensible move for more than just aesthetic or philosophical reasons, though, and luckily the range of options for preserving privacy and private communications have advanced right along with the growth of the technologies that threaten them.

KentuckyFC writes "Arbitrage is a way of making profit by exploiting price differences for the same asset. In capital markets, traders aggressively seek out and exploit these market 'inefficiencies.' Now one data scientist says it's possible to do the same with metro fares and has studied the fare-arbitrage potential of San Francisco's subway system, BART (Bay Area Rapid Transit). The idea is to swap tickets with another commuter during your journey to reduce the amount you both pay. BART has 44 stations which allows 946 different journeys and 446,985 unique pairs of trips. Of these, over 60,000 have arbitrage potential and commuters can save at least $1 on 4,666 of them. But there are good reasons why cities might want to maintain price differences for certain journeys — to encourage people to live in certain areas, for example. What's more, it's possible to imagine a pair of commuters who each travel from one side of a city to the other at considerable cost. But by swapping tickets in the city center, they could both pay for a short commute in each others' suburbs. But is that fair to other commuters?"

jeditobe writes with this announcement from the ReactOS home page: "The ReactOS Project is pleased to announce the release of version 0.3.16. A little under a year has passed since the previous release and a significant amount of progress has been made. More than 400 bugs were eliminated. Some of the most significant include completion of the CSRSS rewrite and the first stages of a shell32 rewrite. 0.3.16 is in many ways a prelude to several new features that will provide a noticeable enhancement to user visible functionality. A preview can be seen in the form of theme support, which while disabled by default can be turned on to demonstrate the Lautus theme developed by community member Maciej Janiszewki. Another user visible change is a new network card driver for the RTL8139, allowing ReactOS to support newer versions of QEMU out of the box." You can download release images here.

fsterman writes "What do you get when you cross physical one-way-functions, a distributed and secure datastore, with physical Bitcoins?

Whatever your thoughts on bitcoin, it's interesting to think about the infrastructure and production cost of the tokens we use as money more generally.

Hugh Pickens DOT Com writes "Bob Sutton reports that in 2012 Adobe moved from yearly performance rankings to frequent "check-ins" where managers provide employees targeted coaching and advice. There is no prescribed format or frequency for these conversations, and managers don't complete any forms or use any technologies to guide or document what happens during such conversations. They are simply expected to have regular check-ins to convey what is expected of employees, give and get feedback, and help employees with their growth and development plans. 'The aim is to give people information when they need it rather than months after teachable moments have passed,' writes Sutton. Donna Morris, Adobe's senior vice president for People and Places, says her team calculated that annual reviews required 80,000 hours of time from the 2000 managers at Adobe each year, the equivalent of 40 full-time employees. After all that effort, internal surveys revealed that employees felt less inspired and motivated afterwards—and turnover increased. According to Sutton, Adobe's bold move seems to be working. Surveys indicates that most Adobe managers and employees find the new system to be less cumbersome and more effective than the old stack-ranking system where managers must divide employees into groups — for example, maybe 15 percent of people can be assigned the highest rating. 'That goes against our core value of being genuine,' says Ellie Gates, director of management effectiveness at Adobe. 'Our goal should be to inspire people to do their best work.' Since the new system was implemented, voluntary attrition has decreased substantially, while involuntary departures have increased by 50% because the new system requires executives and managers to have regular 'tough discussions' with employees who are struggling with performance issues—rather than putting them off until the next performance review cycle comes around. 'It is reducing unnecessary cognitive load, while at the same time, nudging managers to engage more often and more candidly with direct reports to help them develop their skills and plan their careers,' concludes Sutton. 'It also bolsters accountability because managers have far more responsibility for setting employee compensation than under the old system.'"

KentuckyFC writes "Black holes form when a large star runs out of fuel and collapses under its own weight. Since there is no known force that can stop this collapse, astrophysicists have always assumed that it forms a singularity, a region of space that is infinitely dense. Now cosmologists think quantum gravity might prevent this complete collapse after all. They say that the same force that stops an electron spiraling into a nucleus might also cause the collapsing star to 'bounce' at scales of around 10^-14cm. They're calling this new state a 'Planck star' and say its lifetime would match that of the black hole itself as it evaporates. That raises the possibility that the shrinking event horizon would eventually meet the expanding Planck star, which emerges with a sudden blast of gamma rays. That radiation would allow any information trapped in the black hole to escape, solving the infamous information paradox. If they're right, these gamma rays may already have been detected by space-based telescopes meaning that the evidence is already there for any enterprising astronomer to tease apart."

First time accepted submitter joe5 writes "Like what Elon Musk has done and want to go all Etsy and build your own electric car? That's apparently now possible now thanks to the OSVehicle Tabby — dubbed the first "Open source vehicle" (memo: it may be cool, but it ain't the first). The OSV guys are taking pre-orders for the Tabby starter kit, with both the two-seater or four-seater configurations going for €500. Then you click to add options. (Note: seats is an "option" so that's the level of luxury you are dealing with here.) When the transaction's complete, OSV sends the parts to your home and you can download the plans and start building. Since the Tabby is open source, OSVehicle will also look to a community of owners and tinkerers for suggestions and recommendations."

Do you remember the worries about getting different health care software systems to work with each other as health care providers starting moving away from paper? It's still a problem, but Joanne Rohde's company, Axial Exchange, is working to cure that problem not only as an entrepreneur but also because she has personal reasons to see health care providers communicate better with each other. In a 2012 interview for Huffington Post, she said, "While I was working for Red Hat, I got very sick... I ultimately had to go to 10 doctors to be diagnosed. Going from doctor to doctor, I could not believe I had to start over each time. No one actually talks to each other I became convinced that if I had had all the information, I probably would have been able to figure it out faster." In fact, Joanne got so sick that she quit her job as Red Hat COO after four years with the company. Once she started getting decent treatment for her Fybromyalgia and started getting better, she decided to apply open source principles to health care IT -- and to start a new company to do it. Opensource.com talked with Joanne in September 2013, and in January 2014 she talked with Health Care Finance News for an article titled Patients key to reducing readmissions. A phrase Joanne seems to be using a lot lately is "patient engagement," which has become a major part of Axial Exchange's work to improve communications not only between different health care providers but also between those providers and their patients.

An anonymous reader writes "NBC News reports that, during a 2012 NSA conference called SIGDEV, GCHQ's Joint Threat Research Intelligence Group bragged about using Distributed Denial of Service (DDoS) attacks against members of Anonymous during an operation called Rolling Thunder in 2011 (there is evidence that says it was a SYN flood, so technically it was a simple DoS attack). Regular citizens would face 10 years in prison and enormous fines for committing a DoS / DDoS attack. The same applies if they encouraged or assisted in one. But if you work in the government, it seems like you're an exception to the rule."

An anonymous reader writes "For decades, the focus of auto safety has primarily been on surviving the traumatic impact of crashes through features like air bags and seat belts. But now the focus has shifted to avoiding crashes by developing technology to make future vehicles 'smart' enough to detect and respond to threats, such as an oncoming vehicle. The technology, known as 'vehicle-to-vehicle,' or "V2V," lets cars 'talk' to each other and exchange safety data, such as speed and position. If a nearby car abruptly changes lanes and moves into another car's blind spot, the car would be alerted. Federal transportation officials did not announce when the new regulations would go into effect but said they hope to propose the new V2V rules before President Barack Obama leaves office in January 2017." Combine this with remote kill-switches or pulse guns, Amber-alert scrolling signs, proliferating cameras, automatic plate recognition and unstoppable text messages from on high for some not-so-distant driving dystopia.

Nate the greatest writes "Whether it's EA and SimCity, the Sony rootkit scandal, or Ubisoft, we've all read numerous stories about companies using DRM in stupid ways that harm their customers, and now we can add Adobe to the list. Adobe has just announced a new timeline for adoption of their recently launched 'hardened' DRM, and it's going to take your breath away. In a video posted to Youtube, Adobe reps have stated that Adobe expects all of their ebook partners to start adopting the new DRM in March. This is the same DRM that was launched only a few weeks ago and is already causing problems, but that hasn't stopped Adobe. They also expect all the stores that use Adobe's DRM to sell ebooks (as well as the ebook app and ebook reader developers) to have fully adopted the new ebook DRM by July 2014. That's when Adobe plans to end support for the old DRM (which everyone is using now). Given the dozens and dozens of different ebook readers released over the past few years, including models from companies that have gone under, this is going to present a significant problem for a lot of readers. Few, if any, will be updated in time to meet Adobe's deadline, and that's going to leave many readers unable to buy DRMed ebooks."

When we think about NPR (National Public Radio) most of us think of A Prairie Home Companion or another favorite radio show. But NPR also has a research component, NPR Labs, that they say "is the nation's only not-for-profit broadcast technology research and development center." The video (below) is an interview with NPR person Maryfran Tyler about their pilot program designed "to demonstrate the delivery of emergency alerts to people who are deaf or hard-of-hearing in the Gulf Coast states through local public radio stations and the Public Radio Satellite System (PRSS®)." NPR also says, "This is the first effort to deliver real-time accessibility-targeted emergency messages, such as weather alerts, via radio broadcast texts."

Nerval's Lobster writes "Which football team will win the Super Bowl this weekend? That's a multi-million-dollar question, given the amount of cash people will bet on either the Seattle Seahawks or the Denver Broncos to win. Fortunately, Wolfram Alpha (the self-billed "computational knowledge engine") can analyze the historical statistics for both teams and throw out some potentially useful numbers. Developed by Stephen Wolfram and based his Wolfram Research's Mathematica analytical platform, Wolfram Alpha is an altogether different search engine from Bing or Google, which generally return pages of blue hyperlinks in response to queries. Instead of multiple results leading to still other Webpages, Wolfram Alpha usually returns set of definitive, numerical answers. (A lengthy rundown of the engine's capabilities is found on its 'About' page.) So how does Wolfram's engine, which features sophisticated algorithms chewing through trillions of pieces of data, break down the potentials for Sunday's game? Out of the 38 times the two teams have met on the field, the Broncos have triumphed 25 times (versus 12 wins for the Seahawks), scoring 98 total touchdowns to the Seahawks' 84. It's definitely advantage Broncos, in that sense. But the teams' percentages are fairly close with regard to total yardage, penalties, penalty yards, and other metrics, although the Seahawks have managed to nab more interceptions (47, versus the Broncos' 37). But while Wolfram Alpha can crunch all the historical data it wants, and that data can suggest one team will likely triumph over another, there's always the likelihood that something random—a freak injury, or a tweak to the player lineup—can change the course of the game in ways that nobody can anticipate. Also, given how player and coaching rosters vary from year to year, the teams taking the field can change radically between meetings." EA has correctly predicted eight of the last ten Super Bowl winners using the latest Madden game.

swellconvivialguy writes "Fifty-five years ago, nine young Russians died under suspicious circumstances during a winter hiking trip in the Ural mountains. Despite an exhaustive investigation and the recovery of the group's journals and photographs, the deaths remained unexplained, blamed on 'an unknown compelling force.' Now American film and television producer Donnie Eichar believes he has solved the mystery of the Dyatlov Pass Incident. Working in conjunction with scientists at the National Oceanic and Atmospheric Administration in Boulder, CO, Eichar developed a theory that the hikers died because they panicked in the face of infrasound produced by a Kármán vortex street."

Hugh Pickens DOT Com writes: "Up until now, acoustic waves traveling between two points in space always exhibited a basic symmetry summed up with the phrase, 'if you can hear, you can also be heard.' Not anymore; Tia Ghose reports at Live Science that a team at UT Austin has created a 'nonreciprocal acoustic circulator,' the first step that could lead to the sound equivalent of a one-way mirror. All waves — whether visible light, sound, radio or otherwise — have a physical property known as time reversal symmetry — a wave sent one way can always be sent back. For radio waves, researchers figured out how to break this rule using magnetic materials that set electrons spinning in one direction. The resulting radio waves detect the difference in the material in one direction versus the other, preventing reverse transmission. To accomplish the feat with sound waves, the team created a cavity loaded with tiny CPU fans that spin the air with a specific velocity. The air is spinning in one direction, so the flow of air 'feels' different to the wave in one direction versus the other, preventing backward transmission. As a result, sound waves can go in, but they can't go the other way. The result is one-directional sound. With such a device, people can hear someone talking, but they themselves cannot be heard. The findings will likely lead to many useful applications, says Sebastien Guenneau. 'I would be surprised if sound industries do not pick up this idea. This could have great applications in sound insulation of motorways, music studios, submarines and airplanes.'"

Hugh Pickens DOT Com writes: "Benedict Carey writes in the NYT that the idea that the brain slows with age is one of the strongest in all of psychology. But a new paper suggests that older adults' performance on cognitive tests reflects the predictable consequences of learning on information-processing, and not cognitive decline. A team of linguistic researchers from the University of Tübingen in Germany used advanced learning models to search enormous databases of words and phrases. Since educated older people generally know more words than younger people, simply by virtue of having been around longer, the experiment simulates what an older brain has to do to retrieve a word. When the researchers incorporated that difference into the models, the aging 'deficits' largely disappeared. That is to say, the larger the library you have in your head, the longer it usually takes to find a particular word (or pair). 'What shocked me, to be honest, is that for the first half of the time we were doing this project, I totally bought into the idea of age-related cognitive decline in healthy adults,' says lead author Michael Ramscar but the simulations 'fit so well to human data that it slowly forced me to entertain this idea that I didn't need to invoke decline at all.' The new report will very likely add to a growing skepticism about how steep age-related decline really is. Scientists who study thinking and memory often make a broad distinction between 'fluid' and 'crystallized' intelligence. The former includes short-term memory, like holding a phone number in mind, analytical reasoning, and the ability to tune out distractions, like ambient conversation. The latter is accumulated knowledge, vocabulary and expertise. 'In essence, what Ramscar's group is arguing is that an increase in crystallized intelligence can account for a decrease in fluid intelligence,' says Zach Hambrick, In the meantime the new digital-era challenge to 'cognitive decline' can serve as a ready-made explanation for blank moments, whether senior or otherwise (PDF). 'It's not that you're slow,' says Carey. 'It's that you know so much.'"

cartechboy writes "We all talk about the Tesla Model S and Nissan Leaf as if electric cars are brand-new. In fact, electric cars were around long before you were alive, or your father, or maybe even your grandfather. It turns out that the very first Porsche ever built was an electric car--way back in 1898. It wasn't called a Porsche, but an 'Egger-Lohner electric vehicle, C.2 Phaeton model'--or P1 for short. Designed by Ferdinand Porsche when he was just 22 years old, it has a rear electric drive unit producing all of 3 horsepower--and an overdrive mode to boost that to a frightening 5 hp! It had an impressive range of 49 miles, not that much less than many of today's plug-in cars. Porsche recently recovered the P1 from a warehouse--where it has supposedly sat untouched since 1902--and plans to display it in original, unrestored condition at the Porsche Museum in Zuffenhausen, Germany."

First time accepted submitter Kreuzfeld writes "For many years, astronomers have suspected that brown dwarfs — 'failed stars' with masses between those of planets and stars — have cloudy atmospheres. Our recent paper in Nature presents the first global, 2D map of the patchy clouds in the atmosphere of a brown dwarf: our neighbor, the 6.5 light-years-distant Luhman 16B. Eventually, astronomers will use this technique to make weather movies of global cloud patterns on brown dwarfs and extrasolar planets."

Hugh Pickens DOT Com writes "The human body did not evolve to live in space, and the longest any human has been off Earth is 437 days. Some problems, like the brittling of bone, may have been overcome already. Others have been identified — for example, astronauts have trouble eating and sleeping enough — and NASA is working to understand and solve them. But Kenneth Chang reports in the NY Times that there are some health problems that still elude doctors more than 50 years after the first spaceflight. The biggest hurdle remains radiation. Without the protective cocoon of Earth's magnetic field and atmosphere, astronauts receive substantially higher doses of radiation, heightening the chances that they will die of cancer. Another problem identified just five years ago is that the eyeballs of at least some astronauts became somewhat squashed. 'It is now a recognized occupational hazard of spaceflight,' says Dr. Barratt. 'We uncovered something that has been right under our noses forever.' NASA officials often talk about the 'unknown unknowns,' the unforeseen problems that catch them by surprise. The eye issue caught them by surprise, and they are happy it did not happen in the middle of a mission to Mars. Another problem is the lack of gravity jumbles the body's neurovestibular system (PDF) that tells people which way is up. When returning to the pull of gravity, astronauts can become dizzy, something that Mark Kelly took note of as he piloted the space shuttle to a landing. 'If you tilt your head a little left or right, it feels like you're going end over end.' Beyond the body, there is also the mind. The first six months of Scott Kelly's one-year mission are expected to be no different from his first trip to the space station. Dr. Gary E. Beven, a NASA psychiatrist, says he is interested in whether anything changes in the next six months. 'We're going to be looking for any significant changes in mood, in sleep, in irritability, in cognition.' In a Russian experiment in 2010 and 2011, six men agreed to be sealed up in a mock spaceship simulating a 17-month Mars mission. Four of the six developed disorders, and the crew became less active as the experiment progressed. 'I think that's just an example of what could potentially happen during a Mars mission, but with much greater consequence,' says Dr. Beven. 'Those subtle changes in group cohesion could cause major problems.'"

McGruber writes "Like the Mac, the IBM PC Junior first went on sale in late January 1984. That is where the similarities end — the PC Junior became the biggest PC dud of all time. Back on May 17, 1984, the NY Times reported that the PC Junior 'is too expensive for casual home users, but, at the same time, is not nearly powerful enough for serious computer users who can afford a more capable machine.' The article also quoted Peter Norton, then still a human programmer who had not yet morphed into a Brand, who said that the PC Junior 'may well be targeted at a gray area in the market that just does not exist.'' IBM cancelled the machine in March 1985, after only selling 270,000 of them. While it was a commercial flop, the machine is still liked by some. Michael Brutman's PCJr page attempts to preserve the history and technical information of the IBM PCjr and YouTube has a video of a PC Junior running a demo."

eggboard writes "Henk Rogers was a Dutchman who arrived in Japan in the 1980s following a girlfriend (later, his wife). An inveterate D&D player, he became enthralled with the NEC-8801, and nearly killed himself trying to create a D&D-like world that he released as The Black Onyx. No one initially knew what to make of it, and the game sold slowly at first. Through savvy pricing, packaging, and press attention, sales grew, and the game jumpstarted RPGs in Japan. Rogers got left behind, though, as Dragon Quest and Final Fantasy hit a local nerve better than his efforts. 'I also realized that I didn't quite understand the Japanese aesthetic and way. These games were quite different to mine, and just struck a more effective cultural chord.' Rogers went on to license Tetris to Nintendo, though, so he did just fine."

cartechboy writes "Motorsports used to be about lots of horsepower, torque, and big engines. In recent years there's been a shift to downsizing engines, using less fuel, and even using alternative energy such as clean diesel and hybrid powertrains. Today Nissan unveiled a 400-horsepower 1.5-liter three-cylinder turbocharged engine that weighs only 88 pounds. This engine will be part of the advanced plug-in hybrid drivetrain that will power the ZEOD RC electrified race car that will run in the 2015 LMP1 class during the race season. Nissan says the driver of the ZEOD RC will be able to switch between electric power and gasoline power with the batteries being recharged via regenerative braking. Even more impressive, according to Nissan, for every hour the ZEOD RC races, the car will be able to run one lap of the Le Mans' 8.5-mile Circuit de la Sarthe on electric power alone. If true, that will make it the first race car in history to complete a lap during a formal race with absolutely zero emissions. If this all works, we could be witnessing the future of motorsports unfold before our eyes later this year when the ZEOD RC (video) makes its race debut at this year's Le Mans 24 Hours in June."

An anonymous reader writes "Tor Mail was an anonymized email service run over Tor. It was operated by a company called Freedom Hosting, which was shut down by the FBI last August. The owner was arrested for 'enabling child porn,' and the Tor Mail servers suddenly began hosting FBI malware that attempted to de-anonymize users. Now, Wired reports on a new court filing which indicates that the FBI was also able to grab Tor Mail's entire email database. 'The filings show the FBI built its case in part by executing a search warrant on a Gmail account used by the counterfeiters, where they found that orders for forged cards were being sent to a TorMail e-mail account: "platplus@tormail.net." Acting on that lead in September, the FBI obtained a search warrant for the TorMail account, and then accessed it from the bureau's own copy of "data and information from the TorMail e-mail server, including the content of TorMail e-mail accounts," according to the complaint (PDF) sworn out by U.S. Postal Inspector Eric Malecki.'"

Hugh Pickens DOT Com writes "Yale Law School professors Amy Chua, the self-proclaimed 'Tiger Mom,' and her husband Jed Rubenfeld write in the NYT that it may be taboo to say it, but certain ethnic, religious and national-origin groups are doing strikingly better than Americans overall and Chua and Rubenfeld claim to have identified the three factors that account some group's upward mobility. 'It turns out that for all their diversity, the strikingly successful groups in America today share three traits that, together, propel success,' write Chua and Rubenfeld. 'The first is a superiority complex — a deep-seated belief in their exceptionality. The second appears to be the opposite — insecurity, a feeling that you or what you've done is not good enough. The third is impulse control.' Ironically, each element of the Triple Package violates a core tenet of contemporary American thinking. For example, that insecurity should be a lever of success is anathema in American culture. Feelings of inadequacy are cause for concern or even therapy and parents deliberately instilling insecurity in their children is almost unthinkable. Yet insecurity runs deep in every one of America's rising groups; and consciously or unconsciously, they tend to instill it in their children. Being an outsider in a society — and America's most successful groups are all outsiders in one way or another — is a source of insecurity in itself. Immigrants worry about whether they can survive in a strange land, often communicating a sense of life's precariousness to their children. Hence the common credo: They can take away your home or business, but never your education, so study harder. 'The United States itself was born a Triple Package nation, with an outsized belief in its own exceptionality, a goading desire to prove itself to aristocratic Europe and a Puritan inheritance of impulse control,' conclude Chua and Rubenfeld adding that prosperity and power had their predictable effect, eroding the insecurity and self-restraint that led to them. 'Thus the trials of recent years — the unwon wars, the financial collapse, the rise of China — have, perversely, had a beneficial effect: the return of insecurity...America has always been at its best when it has had to overcome adversity and prove its mettle on the world stage. For better and worse, it has that opportunity again today.'"

Rydia writes "Since it first released, I have been in love with my Nokia N900, and it has satisfied all my needs for a mobile with a high degree of control and utility. Sadly, the little guy is showing his age, both in battery life (even with the powersaving kernel options enabled), and performing in general has been left far, far in the dust by phones that are now considered quite old. The time has come to find its successor, but after a thorough search of smartphone options, I can't find any handset that offers everything for the power user that the N900 did (much less a hardware keyboard). I'd like to avoid supporting Google/Android, but there don't seem to be many options. Have any other techies found a replacement for their N900?"

N-Ice.org typically waits until a stable release has been around for a minute to implement the changes into its online client (which is as yet unavailable as a binary for Linux; it varies only slightly from the official release and non-Windows users are able to interface with it no problem), but there are exciting developments coming down the pipe for OpenTTD.

This report [Note: video, with sound] is from the BBC: 'The groundbreaking intelligence work carried out at Bletchley Park during the second world war was credited with bringing forward the end of the conflict. In 2011 the site was awarded a £4.6m grant from the Heritage Lottery Fund (HLF). But Bletchley is currently in the throes of a bitter dispute, between owners who want to create a brand new visitors centre, and volunteers who have been working on the site for years.'"

theodp writes "Valleywag reports on legendary Silicon Valley venture capitalist Tom Perkins' WSJ op-ed on class tensions, in which the KPCB founder and former HP and News Corp. board member likens criticism of the techno-affluent and their transformation of San Francisco to one of the most horrific events in Western history. 'I would call attention to the parallels of Nazi Germany to its war on its "one percent," namely its Jews, to the progressive war on the American one percent, namely the "rich,"' Perkins writes. 'There is outraged public reaction to the Google buses carrying technology workers from the city to the peninsula high-tech companies which employ them. We have outrage over the rising real-estate prices which these "techno geeks" can pay...This is a very dangerous drift in our American thinking. Kristallnacht was unthinkable in 1930; is its descendent 'progressive' radicalism unthinkable now?"'"

First time accepted submitter inqrorken writes "During the recent cold snap, New England utilities turned to an unconventional fuel: jet fuel. Due to high demand for heating, natural gas supplies dropped and prices skyrocketed to $140/mmBtu and prompting the Mid-Atlantic RTO to call on demand response in the region. With 50% of installed generation capacity natural-gas fired, one utility took the step of running its jet fuel-based turbines for a record 15 hours."

theodp writes "Back in 2010, Bill Gates Sr. made the case for I-1098, an initiative for a WA state income tax that Gates argued was needed to address K-12 funding inequity, which he claimed was forcing businesses "to import technically-trained employees, while our own people are shut out of highly paid careers." Opposed by the deep-pocketed, high-tech studded Defeat 1098, the initiative was defeated. Four years later, some of the same high-tech leaders who records show funded Defeat 1098 — including Microsoft CEO Steve Ballmer ($425K), Microsoft General Counsel Brad Smith ($10K), Code.org founder Hadi Partovi ($10K), Amazon CEO Jeff Bezos ($100K), Microsoft Corporation ($75K) — have gotten behind groups like Mark Zuckerberg's FWD.us and Code.org, which are singing a similar Chicken Little tune, telling lawmakers that U.S. students will continue to be shut out of highly paid computer science careers without additional K-12 funding, and the U.S. will lose its competitive edge unless tech is permitted to import even more technically-trained employees. In a departure from Gates' income-tax based solution, Microsoft and Code.org argue that the-problem-is-the-solution, proposing that tech visa fees be used to fund K-12 CS programs. To 'accept that computer science classes are only available to the privileged few,' writes Code.org, 'seems un-American'. So, as some of the nation's biggest K-12 school systems turn to Code.org for CS education programs, should they expect the funding to come from taxes, H-1B tech visa fees, or the-kindness-of-wealthy-strangers philanthropy?"

An anonymous reader writes "Ten years ago today, six and half months after launch, the NASA Jet Propulsion Laboratory's six-wheeled, solar-powered Opportunity rover landed on the surface of Mars, tumbling into a previously unknown feature now referred to as the 'Eagle Crater'. Opportunity and its twin Rover Spirit, which had arrived three weeks earlier, proceeded to crawl over and through plains, craters, and sand dunes, collecting and analyzing soil and rock samples, and taking panoramic photos of their surroundings, blowing orders of magnitude past the original projected 90 day mission timeframe. Spirit's mission drew to a close after it became irretrievably bogged down in soft soil in 2009; scientists lost contact with the rover in early 2010. Meanwhile, Opportunity is still going strong, with scientists announcing new evidence this past week of an ancient mild watery environment conducive to microbial life. Several web sites have mined the NASA archives to assemble tributes commemorating 10 years of work from Opportunity: Time, space.com, Information Week/Techweb. There's also a bricks-and-mortar tribute; the Smithsonian National Air and Space Museum in Washington, DC has just opened an exhibit featuring photos sent by the two rovers."

First time accepted submitter jwpeterson writes "Like chess and go, pentago is a two player, deterministic, perfect knowledge, zero sum game: there is no random or hidden state, and the goal of the two players is to make the other player lose (or at least tie). Unlike chess and go, pentago is small enough for a computer to play perfectly: with symmetries removed, there are a mere 3,009,081,623,421,558 (3e15) possible positions. Thus, with the help of several hours on 98304 threads of Edison, a Cray supercomputer at NERSC, pentago is now strongly solved. 'Strongly' means that perfect play is efficiently computable for any position. For example, the first player wins."
