Programmer Debunks Source Code Shown In Movies and TV Shows
rjmarvin writes "Someone is finally pausing TV shows and movies to figure out if the code shown on screen is accurate or not. British programmer and writer John Graham-Cumming started taking screenshots of source code from movies such as Elysium, Swordfish and Doctor Who, and when it became popular turned the concept into a blog. Source Code in TV and Films posts a new screenshot daily, proving that, for example, Tony Stark's first Iron Man suit was running code from a 1998 programmable Lego brick."

Daily Pot Use Tied To Age of First Psychotic Episode
An anonymous reader writes "Reuters reports, 'In a study of adults who experienced psychosis for the first time, having smoked marijuana daily was linked to an earlier age of onset of the disorder.' ..."This is not a study about the association between cannabis and psychosis, but about the association between specific patterns of cannabis use ... and an earlier onset of psychotic disorders,' Dr. Marta Di Forti, who led the research at the Institute of Psychiatry at Kings College, said in an email. Among more than 400 people in South London admitted to hospitals with a diagnosed psychotic episode, the study team found the heaviest smokers of high-potency cannabis averaged about six years younger than patients who had not been smoking pot. Psychosis is a general term for a loss of reality, and is associated with several psychiatric diseases, including schizophrenia and bipolar disorder. ... "The thorny question is whether they might otherwise have developed the disease or would have not had mental illness. It's a distinction we haven't figured out yet," Compton said. ... It is still unclear whether there are safe levels of use for cannabis, she added. '"

How Chris Christie Could Use the NSA Playbook
Hugh Pickens DOT Com writes "Conor Friedersdorf has written a tongue-in-cheek article in The Atlantic advising New Jersey Governor Chris Christie how he can use the NSA playbook to successfully defend himself of the charges that a senior member of his staff was involved in shutting down George Washington Bridge traffic, a stunt meant to punish the mayor of an affected town for opposing his reelection. Christie's NSA-inspired explanation would include the following points: There are almost 9 million people in New Jersey, and only one was targeted for retribution, an impressively tiny error rate lower than .001 percent; The bridge closure was vital to national security because [redacted]; Since the George Washington Bridge is a potential terrorist target, everything that may or may not have happened near it is a state secret; Going after a political rival is wrong but it's important to put this event in context; Fort Lee Mayor Mark Sokolich was the only target of non-compliant behavior. No other Fort Lee resident was ever targeted for retribution, and any delays that any Fort Lee resident experienced were totally inadvertent and incidental; Finally a panel will be formed to figure out how to restore the public's faith in Chris Christie. "To some readers, these talking points may seem absurd or deliberately misleading," concludes Friedersdorf, "but there isn't any denying that so far they're working okay for the NSA.""

China Tops Europe In R&D Intensity
ananyo writes "By pouring cash into science and technology faster than its economy has expanded, China has for the first time overtaken Europe on a key measure of innovation: the share of its economy devoted to research and development. In 2012, China invested 1.98% of its gross domestic product (GDP) into R&D — just edging out the 28 member states of the European Union, which together managed 1.96%, according to the latest estimates of research intensity, to be released this month by the OECD. The figures show that China's research intensity has tripled since 1998, whereas Europe's has barely increased (see graph). The numbers are dominated by business spending, reflecting China's push in the manufacturing and information- and communication-technology industries."

Steam Controller Hands-on
Ars Technica has posted their impressions from a hands-on session with Valve's new Steam Controller. The controller notably departs from standard practice of relying on two thumbsticks for precise movement, instead replacing them with concave touchpads. From the article: "When used as a kind of virtual trackball, as most games did with the right pad, it was a revelation. When used as a virtual d-pad, as it was on the left pad, it was an exercise in frustration. Let's focus on the right pad first. There's definitely a learning curve to using this side of the pad properly; years of muscle memory had me trying to use it like an analog stick (minus the stick) at first. It only really began to click when I started swiping my thumb over the pad, as I've seen in previous videos (there was no one on hand to really explain the controller to me, so I was left figuring it out on my own, just like a new Steam Machine owner). When I say it "started to click," I mean that literally. The subtle clicking in your hands as you swipe along the pad is an incredible tactile experience, as if there was an actual weighted ball inside the controller that's rolling in the direction you swipe. And like a trackball slowly losing its inertia, the clicking slows its pace after you lift your thumb off the pad, giving important contextual information for the momentum imparted by your swipe." More write-ups are available about the controller from Gamespot, Gizmodo, and Joystiq.

The Math of Gamification
An anonymous reader writes "The Foursquare blog has an interesting post about some of the math they use to evaluate and verify the massive amount of user-generated data that enters their database. They need to figure out the likelihood that any given datapoint accurately represents reality, so they've worked out a complicated formula that will minimize abuse. Quoting: 'By choosing the points based on a user's accuracy, we can intelligently accrue certainty about a proposed update and stop the voting process as soon as the math guarantees the required certainty. ... The parameters are automatically trained and can adapt to changes in the behavior of the userbase. No more long meetings debating how many points to grant to a narrow use case. So far, we've taken a very user-centric view of p-sub-k (this is the accuracy of user k). But we can go well beyond that. For example, p-sub-k could be "the accuracy of user k's vote given that they have been to the venue three times before and work nearby." These clauses can be arbitrarily complicated and estimated from a (logistic) regression of the honeypot performance. The point is that these changes will be based on data and not subjective judgments of how many "points" a user or situation should get."

Object Blocking Giant Tunnel Borer Was an 8" Diameter Pipe
An anonymous reader writes "A few weeks ago we discussed news that a tunnel boring machine measuring 57.5 feet in diameter was halted underneath Seattle after running into a mysterious object. Project engineers have now figured out what the object is: an 8-inch-diameter pipe. In 2002, researchers for another project — the replacement of the Alaskan Way viaduct — drilled down into the ground to take water samples. They used the 115-ft-long pipe as a well casing. As it turns out, this well site was listed in the contract specifications given to all bidders for the tunnel's construction. In addition, the crew manning the machine noticed that it was chewing up pieces of metal, and they removed part of the pipe and kept going. Only later did they realize that significant damage had been done to the machine's cutting face. Officials aren't sure how long repairs will take, or how much they will cost."

Reverse Engineering a Bank's Security Token
An anonymous reader writes "An engineer from Brazil has posted a technical walkthrough of how he was able to reverse engineer his bank's code-generating security token. He found a way to accurately generate his unlock codes with some custom code and an Arduino clone. (Don't worry: his method doesn't give him access to anybody else's codes.) 'Every exception thrown by this piece of code is obfuscated, as well as many of the strings used throughout the code. That is a major roadblock, since exception messages and strings in general are a great way of figuring out what the code is doing when reverse engineering something. Luckily, their developers decided to actually show useful text when a problem occurs and an exception gets thrown, so they wrapped those obfuscated strings with a.a, presumably a decryption routine that returns the original text. That routine is not too straightforward, but it is possible to get a high level understanding of what it is doing.'"

Eye Tracking Coming To Video Games
An anonymous reader writes "Over the past several years, we've had a spate of new input methods for playing video games. Instead of just pushing buttons, now we can wave body parts around, yell at the screen, or even (weakly) control things with our thoughts. Now, we're adding an eye-tracking sensor bar. It's being created by SteelSeries, but it's based on tech from a Swedish company called Tobii, who built similar tech for cars. 'Inside the device there are two cameras and an infrared light source. The infrared light reflects off your pupil and cornea, which is then captured by the two camera sensors. Throw in a healthy serving of Tobii's proprietary image processing algorithms, and a physiological 3D model of the eye, and you can work out the position of the eye and the direction of the gaze with high accuracy. Tobii doesn't seem to put an exact figure on the resolution/accuracy, merely saying that "within less than a centimeter" is possible.' Of course, the biggest question will be how well it works, but it seems like it could be a useful supplement to normal control schemes. I can see how it would be nice to simply flick your eyes to an icon to do something, or to make it easier to dig through your in-game inventory."

Losing Aaron
theodp writes "It's said that you can't fully understand someone until you meet their family. In Janelle Nanos's 'Losing Aaron,' you'll meet Bob Swartz, father of the late Aaron Swartz and adviser to MIT's Media Lab, and get a better understanding of how Aaron's family helped plant the seeds of his idealism. You'll also, sadly, see how MIT — the institution which Bob Swartz long felt stood for compassion and creativity, challenging authority, and pure scientific inquiry — took a self-described stance of 'neutrality' in the aggressive prosecution of his son that ended with Aaron's senseless death last January. 'Clearly I failed,' a tortured Bob Swartz acknowledges. 'There's no question, my son is dead. On the other hand, do I feel that I didn't try hard enough? Yes. Do I feel guilt about not trying hard enough? No. If you understand the distinction I'm trying to make. Could I have done more? Of course I could have done more. Because you can always do more. Did I put everything in that I possibly could? Did I work as hard pretty much as I knew how? Yes. Do I wish I did more? Yes. But I don't go home at night and say, "Well, you didn't care." Because I did. I cared about it more than anything else. And I don't go home at night and say, "I didn't try." Because I tried. Everything I could figure out. But I failed.'"

Reducing Climate Change Uncertainty By Figuring Out Clouds
Most climate scientists agree that the Earth's climate is getting warmer, but models predicting the severity of the temperature rise span a (relatively) broad range. One big reason for this is the difficulty in modeling things like cloud cover and how different air masses mix and move around each other. "Specifically, they have differences in how water-rich air at the bottom of the atmosphere gets mixed with the layers immediately above it. In some cases, this mixing increases rapidly as the temperature rises, effectively drying out the lower atmosphere and suppressing cloud formation there. This in turn would enhance the warming effect. In others, the increase in mixing is more gradual, limiting the impact of warming on clouds. The former produces a higher climate sensitivity; the latter a lower one. ... So, the authors turned to the atmosphere, using data to determine the relative importance of these processes (abstract). In the end, they find that the models that dry out the lower atmosphere more quickly are likely to get the process right. And, in these models, the mixing increases the drying rate in the lower atmosphere by about five to seven percent for each Kelvin the Earth's temperature increases. In contrast, the rate of evaporation, which adds moisture to the lower atmosphere, only increases by two percent for each Kelvin. Thus, the lower atmosphere dries out, cloud formation there is suppressed, and the planet warms even further. How much more will it warm? Quite a bit."

No Question: Snowden Was 2013's Most Influential Tech Figure
Nerval's Lobster writes "Lots of CEOs, entrepreneurs, and developers made headlines in 2013—but in hindsight, Edward Snowden will likely stand as this year's most influential figure in technology. In June, Snowden began feeding top-secret documents detailing the National Security Agency's surveillance programs to The Guardian and other newspapers. Much of that information, downloaded by Snowden while he served as a system administrator at an NSA outpost in Hawaii, suggested that the U.S. government swept up massive amounts of information on ordinary Americans as part of its broader operations. Whatever one's feelings on the debate over privacy and security, it's undeniable that Snowden's documents have increased general awareness of online vulnerability; but whether that's sparked an increased use of countermeasures—including encryption tools—is another matter entirely. On the developer side of things, when you consider the sheer amount of money, time, and code that'll be invested over the next few years in encryption and encryption-breaking, it's clear that Snowden's influence will be felt for quite some time to come—even if the man himself is trapped in Russian exile."

Brain Function "Boosted For Days After Reading a Novel"
cold fjord writes "The Independent reports, 'Being pulled into the world of a gripping novel can trigger actual, measurable changes in the brain that linger for at least five days after reading ... The new research, carried out at Emory University ... found that reading a good book may cause heightened connectivity in the brain and neurological changes that persist in a similar way to muscle memory. The changes were registered in the left temporal cortex, an area of the brain associated with receptivity for language, as well as the primary sensory motor region of the brain. Neurons of this region have been associated with tricking the mind into thinking it is doing something it is not, a phenomenon known as grounded cognition — for example, just thinking about running, can activate the neurons associated with the physical act of running. "The neural changes that we found associated with physical sensation and movement systems suggest that reading a novel can transport you into the body of the protagonist," said neuroscientist Professor Gregory Berns, lead author of the study. "We already knew that good stories can put you in someone else's shoes in a figurative sense. Now we're seeing that something may also be happening biologically."'"

The Rise of Hoax News
Hugh Pickens DOT Com writes "Reporter Luke O'Neil writes that 2013 was journalism's year of bungles: the New Jersey waitress who received a homophobic comment on the receipt from a party she had served; Samsung paying Apple $1 billion in nickels; former NSA chief Michael Hayden's assassination; #CutForBieber; Nelson Mandela's death pic; that eagle snatching a child off the ground on YouTube; Jimmy Kimmel's 'twerk fail' video; and Sarah Palin taking a job with Al-Jazeera America (an obviously satirical story that even suckered in The Washington Post). All these stories had one thing in common: They seemed too tidily packaged, too neat, 'too good to check,' as they used to say, to actually be true. 'Any number of reporters or editors at any of the hundreds of sites that posted these Platonic ideals of shareability could've told you that they smelled, but in the ongoing decimation of the publishing industry, fact-checking has been outsourced to the readers,' writes O'Neil. 'This is not a glitch in the system. It is the system. Readers are gullible, the media is feckless, garbage is circulated around, and everyone goes to bed happy and fed.' O'Neil says that the stories he's written this year that took the least amount of time and effort usually did the most traffic while his more in-depth, reported pieces didn't stand a chance against riffs on things predestined to go viral. That's the secret that Upworthy, BuzzFeed, MailOnline, Viral Nova, and their dozens of knockoffs have figured out: You don't need to write anymore—just write a good headline and point. 'As Big Viral gets bigger, traditional media organizations are scrambling to keep pace,' concludes O'Neil. 'We the media have betrayed your trust, and the general public has taken our self-sanctioned lowering of standards as tacit permission to lower their own.'"

90 Percent of Businesses Say IP Is "Not Important"
langelgjm writes "In 2009, the National Science Foundation teamed up with the Census Bureau to ask U.S. businesses how important intellectual property was to them. Now, after three years of surveys, the results are in. Astonishingly, it turns out that when asked, 90 percent of businesses say intellectual property is 'not important'. While some very large businesses and specific sectors indicate that patents, copyrights, and trademarks are important, overall, the figures are shockingly low. What's more, the survey's results have received hardly any press. It appears that formal intellectual property protection is far less important to the vast majority of U.S. businesses than some federal agencies, such as the patent office, are willing to admit."

How Asimov's Three Laws Ran Out of Steam
An anonymous reader writes "It looks like AI-powered weapons systems could soon be outlawed before they're even built. While discussing whether robots should be allowed to kill might like an obscure debate, robots (and artificial intelligence) are playing ever-larger roles in society and we are figuring out piecemeal what is acceptable and what isn't. If killer robots are immoral, then what about the other uses we've got planned for androids? Asimov's three laws don't seem to cut it, as this story explains: 'As we consider the ethical implications of having robots in our society, it becomes obvious that robots themselves are not where responsibility lies.'"

BitTorrent Unveils Secure Chat To Counter 'NSA Dragnet Surveillance'
Hugh Pickens DOT Com writes "Jacob Kastrenakes reports on The Verge that as part a response to the NSA's wide-reaching surveillance programs, BitTorrent is unveiling a secure messaging service that will use public key encryption, forward secrecy, and a distributed hash table so that chats will be individually encrypted and won't be stored on some company's server. 'It's become increasingly clear that we need to devote hackathons, hours and resources to developing a messaging app that protects user privacy,' says Christian Averill, BitTorrent's director of communications. Because most current chat services rely on central servers to facilitate the exchange of messages, 'they're vulnerable: to hackers, to NSA dragnet surveillance sweeps.' BitTorrent chat aims to avoid those vulnerabilities through its encryption methods and decentralized infrastructure. Rather than checking in with one specific server, users of BitTorrent chat will collectively help each other figure out where to route messages to. In order to get started chatting, you'll just need to give someone else your public key — effectively your identifier. Exchanging public keys doesn't sound like the simplest way to begin a chat, but Averill says that BitTorrent hopes to make it easy enough for anyone interested. 'What we're going to do is to make sure there are options for how this is set up,' says Averill. 'This way it will appeal to the more privacy conscious consumer as well as the less technically inclined.' For now, it remains in a private testing phase that interested users can apply for access to. There's no word on when it'll be open to everyone, but with all of the recent surveillance revelations, it's easy to imagine that some people will be eager to get started."

Using Supercomputers To Find a Bacterial "Off" Switch
Nerval's Lobster writes "The comparatively recent addition of supercomputing to the toolbox of biomedical research may already have paid off in a big way: Researchers have used a bio-specialized supercomputer to identify a molecular 'switch' that might be used to turn off bad behavior by pathogens. They're now trying to figure out what to do with that discovery by running even bigger tests on the world's second-most-powerful supercomputer. The 'switch' is a pair of amino acids called Phe396 that helps control the ability of the E. coli bacteria to move under its own power. Phe396 sits on a chemoreceptor that extends through the cell wall, so it can pass information about changes in the local environment to proteins on the inside of the cell. Its role was discovered by a team of researchers from the University of Tennessee and the ORNL Joint Institute for Computational Sciences using a specialized supercomputer called Anton, which was built specifically to simulate biomolecular interactions among proteins and other molecules to give researchers a better way to study details of how molecules interact. 'For decades proteins have been viewed as static molecules, and almost everything we know about them comes from static images, such as those produced with X-ray crystallography,' according to Igor Zhulin, a researcher at ORNL and professor of microbiology at UT, in whose lab the discovery was made. 'But signaling is a dynamic process, which is difficult to fully understand using only snapshots.'"

Bots Now Account For 61% of Net Traffic
codeusirae writes "A study by Incapsula suggests 61.5% of all website traffic is now generated by bots. The security firm said that was a 21% rise on last year's figure of 51%. From the article: 'Some of these automated software tools are malicious - stealing data or posting ads for scams in comment sections. But the firm said the biggest growth in traffic was for 'good' bots. These are tools used by search engines to crawl websites in order to index their content, by analytics companies to provide feedback about how a site is performing, and by others to carry out other specific tasks - such as helping the Internet Archive preserve content before it is deleted.'"

US Issues 30-Year Eagle-Killing Permits To Wind Industry
Hugh Pickens DOT Com writes "Lindsay Abrams reports at Salon that the Obama administration is offering wind farms 30 years of leeway to kill and harm bald and golden eagles. The new regulations, which were requested by the wind industry, will provide companies that seek a permit with legal protection, preventing them from having to pay penalties for eagle deaths (PDF). An investigation by the Associated Press earlier this year documented the illegal killing of eagles around wind farms, the Obama administration's reluctance to prosecute such cases and its willingness to help keep the scope of the eagle deaths secret. President Obama has championed the pollution-free energy, nearly doubling America's wind power in his first term as a way to tackle global warming. Scientists say wind farms in 10 states have killed at least 85 eagles since 1997, with most deaths occurring between 2008 and 2012, as the industry was greatly expanding. Most deaths — 79 — were golden eagles that struck wind turbines. However the scientists said their figure is likely to be 'substantially' underestimated, since companies report eagle deaths voluntarily and only a fraction of those included in their total were discovered during searches for dead birds by wind-energy companies. The National Audubon Society said it would challenge the decision."
