KentuckyFC (1144503) writes "The origin of the heat generated inside the Earth is one of the great mysteries of geophysics. Researchers know that almost all this heat is generated by the decay of radioactive elements such as potassium-40, thorium-232 and uranium-238. But what they don't know is how these elements are distributed inside the planet and how much heat each contributes. In the next few years, they hope to get some answers thanks to the emerging science of antineutrino geophysics. Since radioactive decay produces antineutrinos, an experiment that measures these particles coming out of the Earth should provide a detailed picture of the distribution of the elements within it.

But there's a problem. Nuclear reactors also produce copious numbers of antineutrinos and these can swamp the signal from inside the Earth. What's needed is a map showing the distribution of reactor antineutrinos so that geophysicists can choose the best places to put their experiments. Just such a map is exactly what a team of nuclear physicists has now produced. The map shows that planned experiments in Hawaii and Curacao, off the coast of Venezuela, are in excellent locations and that Japan has recently become a much better site thanks to the shut down of the country's nuclear industry following the 2011 Tohoku earthquake. But a European experiment currently being planned in south-east France doesn't come off so well."

An anonymous reader writes with good news for advocates of Full Disclosure of security vulnerabilities. A week ago, the venerable full-disclosure list was shut down; now, a successor has arisen run by fyodor. From the announcement email: "As an F-D subscriber and occasional poster myself, I was as shocked as you all last week when John Cartwright threw in the towel and shuttered the list. Now I don't blame him one bit. He performed a thankless job admirably for 12 years and deserves some time off. But I, for one, already miss Full Disclosure. So I decided to make a new list today which is a successor in name and spirit. Like the old one, it uses Mailman and is being archived by my Seclists.org site as well as numerous other archives around the world. This list is a fresh start, so the old userbase won't automatically transfer over. And I haven't added any of you either, because it is your choice. ... I hope you'll join us and resume posting your security info and advisories. If not now, then someday."

An anonymous reader writes: "Scientists at the Nanyang Technological University have developed a solar cell that not only converts sunlight into electricity but also emits light as electricity passes through it. Tuning the composition of the solar cell enables it to emit different wavelengths of light (abstract), and because it is only about 1 micrometer thick, the material is semi-translucent and therefore could potentially be used in windows. The solar cell is comprised of the semiconducting mineral perovskite, which has been studied as a replacement for silicon in solar panels since 2009. Perovskite solar cells are not yet as efficient at energy conversion as silicon solar cells, but gains in this area of development coupled with cheaper manufacturing costs (10-20 cents per watt projected as opposed to 75 cents per watt with silicon solar panels and 50 cents per watt with fossil fuels) make perovskite a popular subject matter in the solar cell industry."

Hugh Pickens DOT Com (2995471) writes "Tolkien was often criticized by his academic colleagues for wasting time on fiction, even though that fiction has probably done more to popularize medieval literature than the work of 100 scholars. Now John Garth reports that HarperCollins plans to publish Tolkien's long-awaited 1926 translation of the oldest surviving Old English epic poem about Beowulf, a hero of the Geats, who kills the monster Grendel with his bare hands and Grendel's mother with a sword of a giant that he found in her lair. Verlyn Flieger, identifies Beowulf as representing one of the two poles of Tolkien's imagination: the darker half, in which we all face eventual defeat – a complete contrast to the sudden joyous upturn of hope that he also expresses so superbly. 'In truth,' writes Garth, 'it is his ability to move between the two attitudes that really lends him emotional power as a writer.' Tolkien pushed the monsters to the forefront arguing that they 'represent the impermanence of human life, the mortal enemy that can strike at the heart of everything we hold dear, the force against which we need to muster all our strength – even if ultimately we may lose the fight.' Without the monsters, the peculiarly northern courage of Beowulf and his men is meaningless. Tolkien, veteran of the Somme, knew that it was not. 'It will be fascinating to see how [Tolkien] exercised his literary, historical and linguistic expertise on the poem,' concludes Garth adding that Tolkien was the arch-revivalist of literary medievalism, who made it seem so relevant to the modern world. 'I can't wait to see his version of the first English epic.'"

Twitter has only just turned eight years old, but in that time it's become so pervasive that some of its conventions have spread beyond Twitter itself, and its character limit seems almost like a natural law. Now, Buzzfeed reports that some Twitter-isms may be about to change: based on screenshots of interfaces in alpha testing, it seems that hashtags and "at" replies may be on the chopping block, or (based on some updates made to the story) at least made less visible for some readers.

Hugh Pickens DOT Com (2995471) writes "The NYT reports that US intelligence analysts studying satellite photos of Iranian military installations say that Iran is building a mock-up of an American nuclear-powered aircraft carrier with the same distinctive shape and style of the Navy's Nimitz-class carriers, as well as the Nimitz's number 68 neatly painted in white near the bow. Mock aircraft can be seen on the flight deck. The mock-up, which American officials described as more like a barge than a warship, has no nuclear propulsion system and is only about two-thirds the length of a typical 1,100-foot-long Navy carrier. Intelligence officials do not believe that Iran is capable of building an actual aircraft carrier. "Based on our observations, this is not a functioning aircraft carrier; it's a large barge built to look like an aircraft carrier," says Cmdr. Jason Salata. "We're not sure what Iran hopes to gain by building this. If it is a big propaganda piece, to what end?" Navy intelligence analysts surmise that the vessel, which Fifth Fleet wags have nicknamed the Target Barge, is something that Iran could tow to sea, anchor and blow up — while filming the whole thing to make a propaganda point, if, say, the talks with the Western powers over Iran's nuclear program go south. "It is not surprising that Iranian military forces might use a variety of tactics — including military deception tactics — to strategically communicate and possibly demonstrate their resolve in the region," said an American official who has closely followed the construction of the mock-up. The story has set off chatter about how weird and dumb Iran is for building this giant toy boat but according to Marcy Wheeler if you compare Iran's barge with America's troubled F-35 program you end up with an even bigger propaganda prop. "I'm not all that sure what distinguishes the F-35 except the cost: Surely Iran hasn't spent the equivalent of a trillion dollars — which is what we'll spend on the F-35 when it's all said and done — to build its fake boat," writes Wheeler. "So which country is crazier: Iran, for building a fake boat, or the US for funding a never-ending jet program?""

Bennett Haselton writes this week with a dissection of the effects of one well-known, long-known problem with so-called Internet filters. "The New Braunfels Republican Women, the Weston Community Children's Association, and the Rotary Club of Midland, Ontario are among the sites categorized as 'pornography' by Blue Coat, a California-based Internet blocking software company. While the product may not be much worse than other Internet filtering programs in that regard, it reinforces the point that miscategorization of sites as 'pornographic' is a routine occurrence in the industry, and not just limited to a handful of broken products." Read on below for the rest.

On Monday I released a blog post through the Citizen Lab at the University of Toronto, listing some of the sites that we had found to be blocked by Blue Coat's Internet filtering program. Previously we had released a similar report on sites that were miscategorized as "pornography" by Smartfilter. We ran some of the same URL lists through both programs, and found that some unfortunate sites were even blocked as "pornography" by both products, including Barenboim-Said (a youth orchestra featuring musicians from Israel, Palestine, and different Arab nations), and the aforementioned New Braunfels Republican Women.

The full list of sites we said were "miscategorized" is at the end of the Citizen Lab blog post. As far as I know we didn't miss any porn hidden on any of the sites that were in the list. The closest we came was a photo on performancespace.org/ showing what appears to be a model taking one for the team by lying on the floor of a grungy art exhibit. There was also the other borderline case of http://safe-sex.org/, which does include articles on topics like "Safe Sex with Expensive London Escorts." But Blue Coat's own working definition of 'pornography' defines it as "Sites that contain sexually explicit material for the purpose of arousing a sexual or prurient interest," and the articles on Safe-Sex.org do not appear intended to arouse ("The heartwarming fact about having safe sex with expensive London escorts is that they usually present a clean bill of health to clients."), so it gets counted as a miscategorization. The overwhelming majority of miscategorized sites were completely G-rated fare like the Kiddie Kollege Nursery School (which, by the way, would probably have grounds for a lawsuit against Blue Coat, if parents trying to access their website were greeted with a message that it had been blocked for containing "pornography").

Anyone can play the parlor game of examining blocked websites looking for signs of what caused them to be blocked. Is the website of the New Braunfels Republican Women blocked by both Blue Coat and Smartfilter because it has the word "women" in the title? (Tempting to thing so, but unlikely, since there are so many other sites with "women" in the name which were not blocked by either product.) One of the blocked websites, http://www.foundations4betterliving.org/, until recently contained statistics such as "A growing variety of sexual behaviour is being practiced by teens 15- to 19-year-old... 53% admit to masturbating; 49% have participated in oral sex; 11% have had anal sex," all of which you could read on their front page while Bette Midler's 'From A Distance' auto-played in the background. (I was hoping to introduce you to that sublime experience, but unfortunately the domain apparently expired right after the report was published. When you list 150 domain names in a report, that's bound to happen with some of them.) And there's neobit.org/, the homepage of a manufacturer of emulators for dongles. While many Americans probably heard the term for the first time when Amy Poehler asked the Best Buy salesman "Can I use a dongle with this? Does it make you uncomfortable when I use the word 'dongle'?", the eggheads at Blue Coat should know what a dongle actually is. 'Dongle' has never been generally accepted anatomical slang, one rogue entry at the Urban Dictionary notwithstanding.

On the other hand, most websites in the report are not only not pornographic, they don't even seem to contain any content that could have triggered an accidental block. So it's quite possible that Blue Coat simply blocks a certain number of sites as a result of some pseudo-random process, and just by chance, some of those sites happen to contain content which looks like it might have caused the block, but the content actually had nothing to do with it.

Still, that leaves open the question of why so many sites turned up blocked by both Blue Coat and Smartfilter. Out of about 150 sites miscategorized by Smartfilter and about 150 sites miscategorized by Blue Coat, 8 sites showed up on both lists, or about 6%. (That group of 8 is listed in the middle of the blog post, beginning with balticsail.org.) Now if either Smartfilter or Blue Coat were blocking non-pornographic sites completely at random, then the percentage of overlap should be about the same as the percentage of non-pornographic sites that the product blocks generally. (For example: Suppose Blue Coat blocked 1% of non-pornographic sites completely at random. Out of 150 non-pornographic sites blocked by Smartfilter, we would therefore expect 1% of them -- about 1 or 2 sites -- to also be blocked by Blue Coat.) But despite the huge number of errors made by both products, neither of them comes close to blocking 6% of all non-pornographic websites as "pornography"; the percentage of overlap is much higher than we would expect if the blocking were random.

So this suggests that some factor is at work that caused the 8 sites in that list to be more likely than average to be blocked, such that they ended up blocked by both products. Did any of the domain names used to be registered to a porn site? It seems hard to imagine that balticsail.org or barenboimsaidusa.org/ could have ever been in demand as domain names used to advertise porn. moriah.org/ sounds like it possibly could have been (many domain names consisting solely of female first names are registered to porn sites), but according to the Wayback Machine, the a previous owner was a Christian band, before the domain expired and was bought by its present-day owner, a Jewish boarding school. Perhaps the IP addresses of these sites used to be held by porn companies, but then why would the products block the sites by their domain name as well? So I really don't know.

The good news is that, unlike Smartfilter, at least Blue Coat's blacklist doesn't appear to be used by any countries for nationwide Internet censorship. Citizen Lab had previously discovered installations of Blue Coat Internet blocking software in 19 "countries of interest" with poor human rights records, but none of them appeared to be set up to filter Internet traffic in and out of the country. In the one country where the product was being used for statewide Internet filtering, the United Arab Emirates, the Blue Coat software was being used in conjunction with Smartfilter's blacklist, so the sites that are mis-blocked by Blue Coat are not blocked in that country (unless of course they also happen to be mis-blocked by Smartfilter).

For the time being, it is not against U.S. law for a company to sell Internet censoring software to foreign governments, even with the knowledge that the tools are being used to restrict freedom of speech in a manner that would be considered a human rights violation by international standards, so both companies have made it a core part of their business.

What a bunch of dongles.

alokmenghrajani (2602135) writes with news of Facebook's new Open Source language, Hack. Quoting: "Today we're releasing Hack, a programming language we developed for HHVM that interoperates seamlessly with PHP. Hack reconciles the fast development cycle of PHP with the discipline provided by static typing, while adding many features commonly found in other modern programming languages. ... Traditionally, dynamically typed languages allow for rapid development but sacrifice the ability to catch errors early and introspect code quickly, particularly on larger codebases. Conversely, statically typed languages provide more of a safety net, but often at the cost of quick iteration. We believed there had to be a sweet spot. ... Hack has deep roots in PHP. In fact, most PHP files are already valid Hack files. ... Our principal addition is static typing. We have developed a system to annotate function signatures and class members with type information; our type checking algorithm infers the rest. Type checking is incremental, such that even within a single file some code can be converted to Hack while the rest remains dynamically typed. ... If a function parameter or class member does not have an explicit type annotation, the type checker considers its type to be dynamic, and it does not check the type of that value." In addition to static typing, they've introduced proper closures that capture the lexical environment, generics, collections, and array shapes. The Hack website has more details. There's a fairly complete language manual, tools to infer types in PHP source and annotate the code, and source available under the PHP license.

Rambo Tribble (1273454) writes "Coronal mass ejections, with severity comparable to the 1859 Carrington event, missed Earth by only 9 days in 2012, according to researchers.

From the Reuters article, 'Had it hit Earth, it probably would have been like the big one in 1859, but the effect today, with our modern technologies, would have been tremendous.' The potential global cost for such damage is pegged at $2.6 trillion."

Bismillah (993337) writes "The re-routing of Google's public DNS servers last weekend was yet another example of how easy it is to 'steal the Internet' by abusing today's trust-based networks. Problem is, ISPs don't seem to care about that, or securing DNS which is another attack vector that doesn't require compromising end users' systems. Why isn't more done to secure routing and DNS then?" The route announcement was likely unintentional. The chief scientist at APNIC noted that implementing RPKI would solve the problem, but far too few ISPs bother with it.

sciencehabit writes "For millions of years, nine species of large, flightless birds known as moas (Dinornithiformes) thrived in New Zealand. Then, about 600 years ago, they abruptly went extinct. Their die-off coincided with the arrival of the first humans on the islands in the late 13th century, and scientists have long wondered what role hunting by Homo sapiens played in the moas' decline. Did we alone drive the giant birds over the brink, or were they already on their way out thanks to disease and volcanic eruptions? Now, a new genetic study of moa fossils points to humankind as the sole perpetrator of the birds' extinction. The study adds to an ongoing debate about whether past peoples lived and hunted animals in a sustainable manner or were largely to blame for the extermination of numerous species."

KentuckyFC writes "Imaging is undergoing a quiet revolution at the moment thanks to various new techniques for extracting data from images. Now physicists have worked out how to create an image of an object hidden behind a translucent material using little more than an ordinary smartphone and some clever data processing. The team placed objects behind materials that scatter light such as onion skin, frosted glass and chicken breast tissue. They photographed them using a Nokia Lumina 1020 smartphone, with a 41 megapixel sensor. To the naked eye, the resulting images look like random speckle. But by treating the data from each pixel separately and looking for correlations between pixels, the team was able to produce images of the hidden objects. They even photographed light scattered off a white wall and recovered an image of the reflected scene--a technique that effectively looks round corners. The new technique has applications in areas such as surveillance and medical imaging."

theodp writes "Over at Slate, Sons of Anarchy creator Kurt Sutter argues that Google's anti-copyright stance is just a way to devalue content, which is bad for artists and bad for consumers.

'Everyone is aware that Google has done amazing things to revolutionize our Internet experience,' writes Sutter. 'And I'm sure Mr. and Mrs. Google are very nice people. But the big G doesn't contribute anything to the work of creatives. Not a minute of effort or a dime of financing.

And then, when Hollywood tries to impede that thievery, it's presented to the masses as a desperate attempt to hold on to antiquated copyright laws that will kill your digital buzz. It's so absurd that Google is still presenting itself as the lovable geek who's the friend of the young everyman. Don't kid yourself, kids: Google is the establishment. It is a multibillion-dollar information portal that makes dough off of every click on its page and every data byte it streams. Do you really think Google gives a s**t about free speech or your inalienable right to access unfettered content? Nope. You're just another revenue resource Google can access to create more traffic and more data streams.

Hugh Pickens DOT Com writes "Benedict Carey reports at the NYT that the uncertainties surrounding Malaysia Airlines Flight 370's disappearance are enormous, but naval strategists have been unraveling lost-at-sea mysteries as far back as the U-boat battles of World War II, and perhaps most dramatically in 1968, when an intelligence team found the submarine Scorpion, which sank in the North Atlantic after losing contact under equally baffling circumstances. "The same approach we used with Scorpion could be applied in this case and should be," says John P. Craven who helped pioneer the use of Bayesian search techniques to locate objects lost at sea. "But you need to begin with the right people." The approach is a kind of crowdsourcing, but not one in which volunteers pored over satellite images, like they have in search of Flight 370. "That effort is akin to good Samaritans combing a forest for a lost child without knowing for certain that the child is there," writes Carey.

Instead, forecasters draw on expertise from diverse but relevant areas — in the case of finding a submarine, say, submarine command, ocean salvage, and oceanography experts, as well as physicists and engineers. Each would make an educated guess as to where the ship is, based on different scenarios: the sub was attacked; a torpedo activated onboard; a battery exploded. Craven's work was instrumental in the Navy's search for the missing hydrogen bomb that had been lost in the Mediterranean Sea, off the coast of Spain in 1966 and this is how Craven located the Scorpion. "I knew these guys and I gave probability scores to each scenario they came up with," says Craven. The men bet bottles of Chivas Regal to keep matters interesting, and after some statistical analysis, Craven zeroed in on a point about 400 miles from the Azores, near the Sargasso Sea. The sub was found about 200 yards away.

In the case of the downed Malaysian plane, forecasters might bring in climate and ocean scientists, engineers who worked on building the plane's components and commercial pilots familiar with the route. Those specialists would then make judgments based on the scenarios already discussed as possible causes for the disappearance of Flight 370: terrorism, pilot error, sudden depressurization and engine failure. Sound-detection technology in and around the Indian Ocean may aid this forecasting. The sound of the airliner's fall — if it hit the water — might already have been picked up by submarines watching each other. "In that case the information would be classified," says former submarine commander Alfred Scott McLare, "and we wouldn't know anything until it was released through back channels somehow.""

Daniel_Stuckey writes "With funding from the Bill and Melinda Gates Foundation's Reinvent the Toilet challenge, [a] team has developed a toilet that uses concentrated solar power to scorch and disinfect human waste, turning feces into a useful byproduct called biochar ... a sanitary charcoal material that is good for soils and agriculture. By converting solid waste to biochar (liquid waste is diverted elsewhere, as it's easier to deal with), the toilet thus allows for sanitary waste disposal without huge infrastructure investments. The toilet itself, called the Sol-Char, is a fascinating bit of engineering. In order to sanitize waste without the help of massive treatment facilities, Linden's team instead designed the toilet to scorch waste in a chamber heated by fiber optic cables that pipe in heat from solar collectors on the toilet's roof. 'A solar concentrator has all this light focused in on one centimeter. It'd be fine if we could bring everyone's fecal waste up to that one point, like burning it with a magnifying glass,' Linden said. 'But that's not practical, so we were thinking of other ways to concentrate that light.'"

An anonymous reader writes "Smithsonian Magazine has an article about one of the non-obvious effects of the Chernobyl nuclear meltdown: dead organisms are not decomposing correctly. 'According to a new study (abstract) published in Oecologia, decomposers—organisms such as microbes, fungi and some types of insects that drive the process of decay—have also suffered from the contamination. These creatures are responsible for an essential component of any ecosystem: recycling organic matter back into the soil. Issues with such a basic-level process, the authors of the study think, could have compounding effects for the entire ecosystem.' The scientists took bags of fallen leaves to various areas around Chernobyl and found that locations with more radiation caused the leaves to retain more than half of their original weight after almost a year.

For the first time, it looks as if momentum has built up to the point where people have heard about Pi Day. There are even attempts to sell you Pi-related items as if it was a real holiday. But there is always some one to spoil the party so what ever you do to celebrate don't miss Vi Hart's Anti-Pi Rant video." Thus begins the yearly debate over Pi Day vs. Tau Day (June 28). Phil Plait has a post defending Pi Day's honor, and MIT isn't holding back their Pi Day celebrations. Large-scale celebration of Pi Day began in 1988, mostly through the efforts of physicists Larry Shaw and Ron Hipschmann at the San Francisco Exploratorium. The Exploratorium still runs Pi Day events 26 years later, including Pi-themed processions and pie for dessert. In 2009, Pi Day became semi-official through a vote by the House of Representatives. (They did a better job with Pi than did Indiana, who almost legislated it to be 3.2.)

The best way to celebrate Pi Day is to get together with some friends and talk math over a pie. You could even go for a pizza pie, since a pizza with radius 'z' and height 'a' has volume = pi * z * z * a. If you'd care for a game, head over to the Pi Day Challenge, which features a series of pi-related logic puzzles. Or just spend the day learning about pi.

Cool pi facts: Pi is currently known to about 10 billion decimal places. You can calculate pi using the Fibonacci sequence. A few years ago, Steven Rochen mapped the digits of pi to musical notes and turned it into a violin solo (video). Others have made music from pi as well. Mankind didn't know the first hundred digits of pi until the year 1701. How many digits of pi can you recite? The record for memorization currently stands at 67890 digits. The record for reciting pi while juggling three balls is just under 10,000.

Hugh Pickens DOT Com writes "Kate Murphy reports at the NYT about a growing number of so-called agrihoods, residential developments where a working farm is the central feature, in the same way that other communities may cluster around a golf course, pool or fitness center. At least a dozen projects across the country are thriving, enlisting thousands of home buyers who crave access to open space, verdant fields and fresh food. 'I hear from developers all the time about this,' says Ed McMahon. 'They've figured out that unlike a golf course, which costs millions to build and millions to maintain, they can provide green space that actually earns a profit.'

Agritopia, outside Phoenix, has sixteen acres of certified organic farmland, with row crops (artichokes to zucchini), fruit trees (citrus, nectarine, peach, apple, olive and date) and livestock (chickens and sheep). Fences gripped by grapevines and blackberry bushes separate the farm from the community's 452 single-family homes, each with a wide front porch and sidewalks close enough to encourage conversation. The hub of neighborhood life is a small square overlooking the farm, with a coffeehouse, farm-to-table restaurant and honor-system farm stand. The square is also where residents line up on Wednesday evenings to claim their bulging boxes of just-harvested produce, eggs and honey, which come with a $100-a-month membership in the community-supported agriculture, or CSA, program.

'Wednesday is the highlight of my week,' says Ben Wyffels. 'To be able to walk down the street with my kids and get fresh, healthy food is amazing.' Because the Agritopia farm is self-sustaining, no fees are charged to support it, other than the cost of buying produce at the farm stand or joining the CSA. Agritopia was among the first agrihoods — like Serenbe in Chattahoochee Hills, Ga.; Prairie Crossing in Grayslake, Ill.; South Village in South Burlington, Vt.; and Hidden Springs in Boise, Idaho. 'The interest is so great, we're kind of terrified trying to catch up with all the calls,' says Quint Redmond adding that in addition to developers, he hears from homeowners' associations and golf course operators who want to transform their costly-to-maintain green spaces into revenue-generating farms. Driving the demand, Redmond says, are the local-food movement and the aspirations of many Americans to be gentlemen (or gentlewomen) farmers. 'Everybody wants to be Thomas Jefferson these days.'" The city of Detroit is planning a 26.9-acre urban farm project on one of its vacant high school properties. Produce from the project will be included in meals for students in the district and later to the larger community.

RSA holds big-time annual security conferences. The 2014 U.S. edition had 25,000 attendees, Stephen Colbert as the closing keynote speaker, and a major controversy (and some anger) from potential speakers and attendees over RSA's reputed $10 million contract with NSA to make sure the company's encryption software had back doors the secretive agency could use to spy on people and companies that use RSA software. This is part of a story that might be called The Snowden Revelations if it is made into a movie, but right now it's still controversial, and enough of a bombshell in the IT security industry that F-Secure's Mikko Hyppönen decided not to speak at this year's U.S. RSA conference, followed by Bruce Schneier, DEFCON founder Jeff Moss, Princeton professor Ed Felten, and other security luminaries.

And so, TrustyCon -- the Trustworthy Technology Conference -- was born. It was a sellout, with 400 people attending at $50 a head, and another 300 on a waiting list who couldn't get in. Slashdot's Tim Lord managed to get in, and got to speak briefly with several people there, including one of the TrustyCon organizers, Joel Wallenstrom. These were crude interviews, done on a "catch as catch can" basis, and the sound in them is poor. (Google sent a camera crew and shot over seven hours of the conference speakers, which you can watch on YouTube if you want to view TrustyCon presentations in good HD with great sound.). Will there be another TrustyCon next year? According to The Register, "The conference organizers said that, at this point, the plan is to hold another get-together next year, but that a final decision will be made closer to the time."

theodp writes "'I want to explain why Common Core is among the most important education ideas in years,' wrote Bill Gates in a USA Today op-ed last month that challenged the "dangerous misconceptions" of those who oppose the initiative (pretty confident for a guy who conceded there wasn't much to show for his earlier $5B education reform effort!). 'The Gates Foundation helped fund this process,' acknowledged Gates in quite an understatement of his influence. Receiving $6.5M in Gates Grants was Student Achievement Partners, whose founder David Coleman was dubbed the 'Architect of the Common Core.' So it's not too surprising that at last week's SXSWedu, Coleman — now President and CEO of The College Board (no stranger to Gates money itself) — announced a dramatic overhaul of the SAT that includes a new emphasis on evidence-based reading and writing and evidence analysis, which the AJC's Maureen Downey calls 'reflective of the approach of the Common Core State Standards.'" (Read more, below.) "And over at The Atlantic, Lindsey Tepe reports that the Common Core is driving the changes to the SAT. "Neither Coleman nor the national media," writes Tepe, "have really honed in on how the standards are driving the College Board-as well as the ACT-to change their product." In conjunction with the redesigned SAT, The College Board also announced it would exclusively team with Khan Academy (KA) to make comprehensive, best-in-class SAT prep materials open and free in an effort to level the playing field between those who can and can't afford test prep services. In a conversation with KA founder Sal Khan — aka Bill Gates' favorite teacher and a beneficiary of $10+ million in Gates Foundation grants (much earmarked for Common Core) — Coleman stressed that Khan Academy and CollegeBoard will be the only places in the world that students will be able to encounter free materials for the exam that are "focused on the core of the math and literacy that matters most." "There will be no other such partnerships", Coleman reiterated. Game, set, and match, Gates?"

KentuckyFC writes "The 13th century thinker Robert Grosseteste is sometimes credited with predicting the Big Bang theory of cosmological expansion some eight centuries ahead of modern cosmologists. His theory, written in about 1225, is that the Universe began with a Big Bang-like explosion in which light expands in all directions giving matter its three-dimensional form. The expansion eventually stops when matter reaches a minimum density and this sets the boundary of the Universe. The boundary itself emits light towards the center of the universe and this interacts with matter, causing other nested spheres to form, corresponding to the fixed stars, the elements of earth, fire, water and so on. Now a team of physicists and experts on medieval philosophy have translated Grosseteste's theory into the modern language of mathematics and simulated it on computer. They say Grosseteste's theory produces universes of remarkable complexity but that only a tiny fraction of the parameter space corresponds to a universe of nested spheres like the one he predicted. What's interesting is that modern cosmologists face exactly the same problem. Their models predict many different kinds of universes and have to be fine-tuned to fit the universe we actually live in. 'The sensitivity to initial conditions resonates with contemporary cosmological discussion and reveals a subtlety of the medieval model which historians of science could never have deduced from the text alone,' conclude the team."

cold fjord writes "Phys.org reports, "Alan Turing's accomplishments in computer science are well known, but lesser known is his impact on biology and chemistry. In his only paper on biology (PDF), Turing proposed a theory of morphogenesis, or how identical copies of a single cell differentiate, for example, into an organism with arms and legs, a head and tail. Now, 60 years after Turing's death, researchers from Brandeis University and the University of Pittsburgh have provided the first experimental evidence that validates Turing's theory in cell-like structures. The team published their findings in the Proceedings of the National Academy of Sciences on Monday, March 10.""

phmadore writes "10Gbps cables are what are commonly used in large server centers today, but very soon, according to Ars, 800Gbps cables will be available from Intel. From the article: 'The new cables are based on Intel's Silicon Photonics technology that pushes 25Gbps across each fiber. Last year, Intel demonstrated speeds of 100Gbps in each direction, using eight fibers. A new connector that goes by the name "MXC" holds up to 64 fibers ... The fiber technology also maintains its maximum speed over much greater distances than copper, sending 800Gbps at lengths up to 300 meters, Intel photonics technology lab director Mario Paniccia told Ars. Eventually, the industry could boost the per-line rate from 25Gbps to 50Gbps, doubling the overall throughput without adding fibers, he said.'"

jones_supa writes "A bit surprisingly, Valve Software has uploaded their Direct3D to OpenGL translation layer onto GitHub as open source. It is provided as-is and with no support, under the MIT license allowing you to do pretty much anything with it. Taken directly from the DOTA2 source tree, the translation layer supports limited subset of D3D 9.0c, bytecode-level HLSL to GLSL translator, and some SM3 support. It will require some tinkering to get it to compile, and there is some hardcoded Source-specific stuff included. The project might bring some value to developers who are planning to port their product from Windows to Linux."

There's been some positive news in the last year (and the last few) for American cellphone customers: certainly there's more visible competition for their business among the largest players in the market. Nonetheless, the Wall Street Journal reports that while more competition may translate into some more attractive service bundles, flexibility in phone options, or smoother customer service, it doesn't actually mean that the customers are on average reaping one of the benefits that competition might be expected to provide: lower price. Instead, the bills for customers on the major wireless providers have actually gone up, if not dramatically, in recent months — which means U.S. cell service remains much more expensive than it is in many other countries. The article could stand a sidebar on MVNOs and other low-cost options, though -- I switched to one of these from AT&T, and now pay just under $40 for one version of the new normal of unlimited talk and text, plus quite limited (1GB) data, but still using AT&T towers. Has your own cost to talk gone up or down?

Rubin added, 'Competition is good for the consumer and if somebody has an idea for a feature or a piece of functionality in their platform and Android doesn't do it, great. I think it's good to have the benefit of choice, but in the end I don't think the world needs another platform.' But now, CNET and Digitimes report that Google is holding up the Asus Transformer Book Duet TD300 (specs), a laptop-tablet hybrid that can instantly switch between Android and Windows 8.1. A source familiar with the Asus Duet told CNET that Google is the one that has not favored the idea, while Microsoft has not, to date, been actively opposed to the idea. 'If true,' reports Apple Insider, 'it may not be the first time Google has helped to quash such a product.' South Korean electronics giant Samsung quietly canceled plans for its hybrid Ativ Q tablet last year, and Digitimes notes that Asus may not be the only company to bow to Google's wishes."

Hugh Pickens DOT Com writes "Marcus Stern and Sebastian Jones report on Bloomberg that as federal regulators continue investigating why tank cars on three trains carrying North Dakota crude oil have exploded in the past eight months, energy experts say part of the problem might be that some producers are deliberately leaving too much propane in their product, making the oil riskier to transport by rail. Sweet light crude from the Bakken Shale formation has long been known to be especially rich in volatile natural gas liquids like propane and while there's no way to completely eliminate natural gas liquids from crude, well operators are supposed to use separators at the wellhead to strip out gases before shipping the oil. The worry is that some producers are adjusting the pressure settings to leave in substantial amounts of natural gas liquids and purposefully selling their crude "fluffed up" with propane to maximize their profits." (Read more, below.) "'There is a strong suspicion that a number of producers are cheating. They generally want to simply fill up the barrel and sell it—and there are some who are not overly worried about quality,' says Alan J. Troner. 'I suspect that some are cheating and this is a suspicion that at least some refiners share.' As an oil train shakes, rattles and rolls toward the refinery, the propane begins to separate from the liquid and turning into gas. If one of those cars ruptures, the propane gas inside will likely make contact with outside air. If the gas is ignited—perhaps by a spark thrown off when the car rips open or maybe a spark thrown up from steel wheels scraping over steel tracks—the car can explode. Then the burning car can act like a blowtorch on the tanker next to it and at that point, railcars can explode in domino fashion. The Pipeline and Hazardous Materials Safety Administration (PHMSA) recently issued a safety alert that recent derailments and resulting fires indicate that the type of crude oil being transported from the Bakken region may be more flammable than traditional heavy crude oil. 'It's typical of this type of oil. So it's not surprising. There's no mystery to it especially if it were in a tanker not meant to carry that type of fluid,' says Ramanan Krishnamoorti referring to the much-criticized DOT-111, a black, torpedo-shaped railcar designed in the 1960s that has become the workhorse of the crude-rail industry. Washington doesn't appear to be in a rush to address the problem. On January 23, investigators at the US National Transportation Safety Board made broad recommendations that would have big consequences: They said crude oil should meet the same restrictions as toxic chemicals, which must be routed on tracks away from population centers. 'The large-scale shipment of crude oil by rail simply didn't exist 10 years ago, and our safety regulations need to catch up,' says NTSB Chairman Deborah Hersman. 'While this energy boom is good for business, the people and the environment along rail corridors must be protected from harm.'"

Hugh Pickens DOT Com writes "Dick Ahlstrom reports that Irish researchers have discovered a previously unknown model of the universe written in 1931 by physicist Albert Einstein that had been misfiled and effectively "lost" until its discovery last August while researchers been searching through a collection of Einstein's papers put online by the Hebrew University in Jerusalem. "I was looking through drafts, but then slowly realised it was a draft of something very different," says Dr O'Raifeartaigh. "I nearly fell off my chair. It was hidden in perfect plain sight. This particular manuscript was misfiled as a draft of something else." Read more, below. "In his paper, radically different from his previously known models of the universe, Einstein speculated the expanding universe could remain unchanged and in a " steady state" because new matter was being continuously created from space. "It is what Einstein is attempting to do that would surprise most historians, because nobody had known this idea. It was later proposed by Fred Hoyle in 1948 and became controversial in the 1950s, the steady state model of the cosmos," says O'Raifeartaigh. Hoyle argued that space could be expanding eternally and keeping a roughly constant density. It could do this by continually adding new matter, with elementary particles spontaneously popping up from space. Particles would then coalesce to form galaxies and stars, and these would appear at just the right rate to take up the extra room created by the expansion of space. Hoyle's Universe was always infinite, so its size did not change as it expanded. It was in a 'steady state'. "This finding confirms that Hoyle was not a crank," says Simon Mitton. "If only Hoyle had known, he would certainly have used it to punch his opponents." Although Hoyle's model was eventually ruled out by astronomical observations, it was at least mathematically consistent, tweaking the equations of Einstein's general theory of relativity to provide a possible mechanism for the spontaneous generation of matter. Einstein's paper attracted no attention because Einstein abandoned it after he spotted a mistake and then didn't publish it but the fact that Einstein experimented with the steady-state concept demonstrates Einstein's continued resistance to the idea of a Big Bang, which he at first found "abominable", even though other theoreticians had shown it to be a natural consequence of his general theory of relativity."

Daniel Dvorkin writes "When I first started studying bioinformatics almost fifteen years ago (!) what drew me to the field was the promise that we might soon be able to provide effective, personalized treatments for a wide variety of diseases. There have been some successes along the way, like genetic tests for warfarin dosage, but for the most part our gains in understanding of basic biology haven't been matched by clinical advances. Now it looks like that is at long last about to change, and it's about time.

Too many people suffer and die from too many diseases that we more or less understand, but can't effectively treat. I hated it when I worked in hands-on patient care, and I hate it now in the lab. We are, finally, getting there."

KentuckyFC writes "The way memes evolve on Facebook is startlingly similar to the way genes evolve on Earth. That's conclusion of a team of researchers who have analyzed the evolution of thousands of memes that have appeared more than 460 million times on Facebook. The memes are ideas like: 'No one should die because they cannot afford health care and no one should go broke because they get sick. If you agree please post this as your status for the rest of the day,' which has been copied 470,000 times. However, the meme quickly mutated. A version that included the phrase '[Your Name] thinks that' appeared 60,000 times. And humorous versions appeared too: 'No one should be without beer because they cannot afford one.'

The team analyzed how often variants appeared and how different they were to the original to get a measure of each meme's evolution. It turns out that this evolution follows the same mathematical evolution, called the Yule Process, that genes follow. And there are other similarities too. There is a small but clear preference for variants that are shorter than the original memes. That's analogous to bacteria favoring small genomes because they allow fast replication. And the same advantageous sequences can appear in many different memes, probably transferred by a single individual from one meme to another. This process is analogous to lateral gene transfer in bacteria. There are some differences too. Evolution is a blind process in biology but not in social media there can be a conscious effort to create mutations that will spread more effectively. This leads to some memes evolving with very high replication rates that are not described by the Yule process. The team says the results should provide greater insight into the nature of information transfer in social networks. It also raises the interesting question of how far evolution might go when given a little time to play with memes."

cartechboy writes "Math watch time: For many traffic analysts, INRIX is considered the gold-standard. This week the company says traffic congestion surged in 2013 and grew over three times as fast as the American economy. The bad news: If true, this reverses two consecutive years of traffic declines with a six percent increase in 2013. (GDP, by comparison, grew 1.9 percent last year.) The analysts then theorize links between economic growth and traffic congestion, which makes sense on the surface. (As the economy improves, more jobs are created, so more commuters on the roads) But INRIX's theory creates as many questions as it answers. For example, the U.S. GDP has been steadily growing since 2009. So why did congestion decline in 2011 and 2012?"

Shag writes "Type Ia supernovae are used as cosmological 'standard candles' to measure distance because of their strong similarity to one another. This has made possible, for example, the research into universal expansion that led to the Nobel-winning discovery of 'dark energy.' For years, astrophysicists believed white dwarves exploded when they accreted enough mass from companion stars to reach a limit of 1.38 times the mass of our Sun. A decade ago, the 'Champagne supernova' (SN 2003fg) was so bright astrophysicists concluded the limit had been exceeded by two white dwarves colliding. Now a new paper (PDF) from the Nearby Supernova Factory collaboration suggests that type Ia supernovae occur at a wider range of stellar masses. Fortunately, there appears to be a calculable correlation between mass and light-curve width, so they can still fill the 'standard candle' role, and research based on them is probably still valid. (I took data for the paper, but am not an author.)"
