holy_calamity writes "Technology Review has an in depth profile of the team at Facebook tasked with figuring out what can be learned from all our data. The Data Science Team mine that information trove both in the name of scientific research into the patterns of human behavior and to advance Facebook's understanding of its users. Facebook's ad business gets the most public attention, but the company's data mining technology may have a greater effect on its destiny — and users lives."

sciencehabit writes "The Curiosity rover will definitely find evidence of an advanced civilization if it lands safely on Mars. That's because rock samples the rover drills are likely to be contaminated with bits of Teflon from the rover's machinery, NASA announced during a press teleconference. The bits of Teflon can then mix with the sample, which will be vaporized for analysis. The problem for the scientists is that Teflon is two-thirds carbon — the same element they are looking for on Mars." Fortunately, this problem isn't a showstopper: "...there are still mitigation steps to take if SAM's analysis is potentially compromised. Contaminant production appears to be stronger in the drill's percussion mode, when it pounds powerfully and rapidly on Martian rock. So ratcheting the percussion down, or switching over to the more gentle rotary mode, may make the issue more manageable. If that doesn't work, the MSL team could just take the drill out of commission, solely scooping soil instead of also boring into rock. Curiosity could still access the interior of some Martian rocks by rolling over them with its wheels, Grotzinger said. But all in all, he's confident that the team will figure things out in the next month or two."

Snirt writes "The Nobel Committee has chosen to lower this year's Nobel prize winnings by two million kronor ($283,030) due to turbulence in the current economic climate. The prize now stands at 8 million kronor, down from the 10 million of 2011. 'The reason behind this decision is that the financial markets are really unstable and there are reasons to suspect that this turbulence will continue for a while still,' said Lars Heikensten, head of the Nobel Committee, to the TT news agency. 'Long term, we aim to raise the figure, even though we think that the Nobel Prize's value should lie in the prize itself and not the prize money,' he said. While Heikensten admits that it was a 'tough decision' to cut the prize money, he told the news agency that it's not the first time the prize sum has been altered, adding that it has been lowered and raised several times over the past few years."

New submitter SouthSeaDragon writes "I'm a computer professional who has performed most of the functions that could be expected over a 39 year career, including hardware maintenance and repair, sitting on a 800 support line, developing a help desk application from the ground up (terminal-based), writing a software manual, plus developing and teaching software courses. In recent years, I've worked for computer software vendors doing pre-sales support generally for infrastructure products including applications, app servers, integration with Java based messaging and ESB product and most recently a Business Rules product. I was laid off recently due to a restructuring and am now trying to figure out the next phase. With the WIA displaced worker grants now available I am attempting to figure out what training would be good to pursue. I am hearing that 'the Cloud' is the next big thing, but I'm also looking into increasing my development skills with a current language. I wonder what the readers might suggest for new directions."

carmendrahl writes "The peacock mantis shrimp, a crustacean which is neither a mantis nor a shrimp, has hammer-like clubs for smashing the shells of its prey. They're so strong that regular glass aquariums can't hold them. But what's interested researchers for some time is how the clubs stand up to all that stress. Now, a team has figured out why: the mantis shrimp club's molecular structure is set up to resist fractures. That discovery could lead to stronger and lighter car frames or body armor."

An anonymous reader writes "The Atlantic has an article discussing how 18- to 35-year-old males are losing their place as the most important demographic for tech adoption. 'Let me break out the categories where women are leading tech adoption: internet usage, mobile phone voice usage, mobile phone location-based services, text messaging, Skype, every social networking site aside from LinkedIn, all Internet-enabled devices, e-readers, health-care devices, and GPS. Also, because women still are the primary caretakers of children in many places, guess who controls which gadgets the young male and female members of the family get to purchase or even use?' The article points out that most of the tech industry hasn't figured this out yet — perhaps in part to a dearth of women running these companies."

MikeatWired writes "OpenLogic announced on Thursday that it will provide CentOS Linux — and service-level agreement (SLA) support — through Microsoft's new Windows Azure gallery. Yesterday, Microsoft announced support for Linux instances on its cloud service, among other cloud news, in what Wired Enterprise's Cade Metz dubbed an Amazonian facelift. OpenLogic's Steven Grandchamp writes in a blog post that for 'enterprise developers and IT folks who are multi-source and multi-platform, today's announcement is good news. The Windows and Linux worlds take one step towards each other.' However, Grandchamp notes that despite Microsoft 'maturing its views on open source' with 'significant work' with Node.js, Hadoop, and Samba, the open source community 'will meet [Linux on Azure] with overall wariness and skepticism.' 'Some will view this with hope and a positive step; others will continue to be cynical,' he writes. 'For me, it's part of a larger overall process that continues to signal open source coming of age. What major vendor doesn't have an open source story now? It's such an ingrained part of development, from legacy to mobile to cloud, that we can't live without and we are figuring out how to love living with it.'"

LilaG writes "Who hasn't marveled at the ability of water bugs to skate along the surface of lakes and ponds? Now materials scientists in China have taken a cue from water striders and created a device that can coast along the surface between oil and water. The tricky part was figuring out how to make an oil-repelling surface that worked underwater. It came down to coating copper wires with copper oxide microstructures that look like flowers made up of nanopetals. Scientists think such coatings could enable robots that clean up oil spills, bug-proof car windshields, and ship hulls that don't build up barnacles."

jfruh writes "Booth babes," promotional models paid to showcase products, are ubiquitous figures at tech trade shows. Ever wonder what they think of their jobs? Well, it may not surprise you to learn that standing up for eight hours in heels isn't much fun. Some enjoy the work, while others don't enjoy being the subject of stares. And one model adds that 'The industry is now moving towards making models show more skin.'"

An anonymous reader writes "U.S. Magistrate Judge Stephen Smith estimates in a new paper (PDF) that 30,000 secret surveillance orders are approved each year in U.S. courts. 'Though such orders have judicial oversight, few emerge from any sort of adversarial proceeding and many are never unsealed at all.' Smith writes, 'To put this figure in context, magistrate judges in one year generated a volume of secret electronic surveillance cases more than thirty times the annual number of FISA cases; in fact, this volume of ECPA cases is greater than the combined yearly total of all antitrust, employment discrimination, environmental, copyright, patent, trademark, and securities cases filed in federal court.' He also adds a warning: 'Lack of transparency in judicial proceedings has long been recognized as a threat to the rule of law and roundly condemned in ringing phrases by many Supreme Court opinions.'"

benfrog writes "New York City comptroller John Liu has accused HP of overcharging New York City $163 million on upgrades to its 911 system. According to a statement put out by Liu, an audit of the project revealed that HP did not perform up to spec on the contract between April 2005 and April 2008 and did not bill the city correctly for time and materials on its portion of the contract to upgrade the 911 system. According to Liu's reading, the contract was supposed to cost no more than $378 million over five years, but in January the city projected it would have already spent $307m by mid-April and had to award Northrop-Grumman an additional $286m to do a second part of the original contract, ballooning the cost to $632m, and Liu's office is now estimating that cost overruns beyond this could be as high as an additional $362m. NYC's deputy mayor for operations was quoted defending the contract."

SicariusMan writes "The age old question: do Guinness and other stouts' bubbles really sink, or is it an optical illusion? Well, some mathematicians have figured it out." Full paper via arXiv; From the article: "To analyze the effect of different glass shapes, the mathematicians modeled Guinness beer containing randomly distributed bubbles in both a pint glass and an anti-pint glass (i.e., an upside-down pint). An elongated swirling vortex forms in both glasses, but in the anti-pint glass the vortex rotates in the opposite direction, causing an upward flow of fluid and bubbles near the wall of the glass."

Fluffeh writes "The folks that push 'Anti-Piracy' and 'Copying is Stealing' seem to often request that Google pre-screens content going up on YouTube and of course expect Google to cover the costs. No-one ever really asks the question how much it would cost, but some nicely laid out math by a curious mind points to a pretty hefty figure indeed. Starting with who to employ, their salary expectations and how many people it would take to cover the 72 hours of content uploaded every minute, the numbers start to get pretty large, pretty quickly. US$37 billion a year. Now compare that to Google's revenue for last year."

An anonymous reader writes "A fortnight ago the Bitcoin financial website Bitcoinica was hacked and the hacker stole $87,000 worth of Bitcoins. At the time the owner promised that all users would have their Bitcoins and US dollars returned in full, but one of the site developers has just confirmed that they have no database backups and are having difficulty figuring out what everyone's account balance should actually be. A failure of epic proportions for a site holding such large amounts of money."

pigrabbitbear writes "Who's driving a lot of neuro research? The military. Much of it is health related, like figuring out how to make prosthetics work more seamlessly and helping diagnose brain injuries. But the military's involvement highlights the basic ethical quandary of neurological development: When our brains pretty much define who we are, what happens when you start adding tech in there? And what happens when you take it away? Jonathan Moreno is quite possibly the top bioethicist in the country, and along with Michael Tennison, recently penned a fascinating essay on the role and ethics of using neuroscience for national security. He also recently updated his book Mind Wars, a seminal look into the military's work with the brain. In this interview he discusses brain implants, drones, and what will happen when military tech hits the civilian world."

An anonymous reader writes "First we had a superhydrophobic spray that meant no dirt or sweat could stick to your clothes. Then a hydrophobic nanocoating was created for circuit boards to make them water resistant. Now MIT has gone a step further and solved one of the ongoing problems of using condiments: they've figured out how to make a food-safe superhydrophobic coating for food packaging. It means ketchup and mayonnaise will no longer be stuck to the insides of the bottle, and therefore there will no longer be any waste. What's amusing is this seems to be a happy accident. The MIT team was actually investigating slippery coatings to stop gas and oil lines clogging as well as how to stop a surface from having ice form on it. Now their lab is filled with condiments for continued testing of their food-safe version."

pacopico writes "Businessweek reports that DARPA will pay for the creation of two new TechShops in Washington D.C. and Pittsburgh. The $3.5 million deal includes 2,000 TechShop memberships for military veterans and will have DARPA employees performing top secret work at night. 'The project is called iFab. For a month, a given factory might use dozens of machines to make parts for helicopters. Then you reboot the software controlling the machines, and out come the parts for the drive train system in a tank. The Darpa workers at TechShop will try to figure out which tools and methods can be used to rewire factories in this fashion.' Maker mayhem."

mikejuk writes "A team from Microsoft Research has taken the lead in the MinuteSort data sorting test using a specially-devised technology: Flat DataCenter Storage. The figures are impressive — 1401 gigabytes in 60 seconds, using 1033 disks across 250 machines. Not only is this three times as much as the previous record, but also, it uses only one sixth of the hardware resources, according to a blog post about the test from Microsoft. One thing that's interesting about the success is the technology used. While solutions such as Hadoop and MapReduce are traditionally used for working with large data sets, Microsoft Research created its own technology called the 'Flat Datacenter Storage,' or FDS for short. This isn't just academic research, of course. The team from Microsoft Research has already been working with the Bing team to help Bing accelerate its search results, and there are plans to use it in other Microsoft technologies."

An anonymous reader writes "It looks simple. I've got a laptop and a USB HDD for backups. With rsync, I only move changes to the USB HDD for subsequent backups. I'd like to move these changes to a more portable USB stick when I'm away, then sync again to the USB HDD when I get home. I figured with the normality of the pieces and the situation, there'd be an app for that, but no luck yet. I'm guessing one could make a hardlink parallel-backup on the laptop at the same time as the USB HDD backup. Then use find to detect changes between it and the actual filesystem when it's time to backup to the USB stick. But there would need to be a way to preserve paths, and a way communicate deletions. So how about it? I'm joe-user with Ubuntu. I even use grsync for rsync. After several evenings of trying to figure this out, all I've got is a much better understanding of what hardlinks are and are not. What do the smart kids do? Three common pieces of hardware, and a simple-looking task."

An anonymous reader writes "More than 1,000 UK government staff have been caught snooping on citizen data — including criminal records, social security, and medical records. From the article: 'The U.K. government is haemorrhaging data — private and confidential citizen data — from medical records to social security details, and even criminal records, according to figures obtained through Freedom of Information requests. Just shy of 1,000 civil servants working at the Department for Work and Pensions (DWP), were disciplined for accessing personal social security records. The Department for Health (DoH), which operates the U.K.’s National Health Service and more importantly all U.K. medical records, saw more than 150 breaches occur over a 13-month period.'"
