Submission + - Lockeed "Skunk Works" Announces Fusion Power Demo in Five Years (fusenet.eu)

Required Snark writes:

At the recent Google “Solve for X” conference on February 7, Lockheed Martin's long-term R&D department (“Skunk Works”) announced they are working on a compact fusion reactor. With what seems a 4th generation prototype called "T4", the aerospace giant says to have developed a high beta configuration, which allows a compact reactor design and faster development timeline.

Public reactions describe the announcement of their activities on nuclear fusion remarkable, because Lockheed Martin doesn't usually make public announcements about Skunkwork projects unless they have a high degree of confidence in their chances of success. The developement timeline indicates plans to have a prototype 100-megawatt nuclear fusion machine of Lockheed Martin tested in 2017, and that a fully operational machine should be grid-ready ten years from now.

Some of the properties reported from the presentation:

  • A self-tuning feedback mechanism whereby the magnetic field increases the farther out that the plasma goes
  • Novel magnetic field configuration that has very few open field lines compared to tokamak design
  • Very "good arch curvature" of the field lines The system has a beta of about 1
  • System is working with D-T fuel

Although the presentation is short on details, Lockheed Skunk Words has a phenomenal track record, and they are putting their reputation of the line when they make this kind of announcement at a high profile Google event. A video of the presentation is here.

Submission + - Draft IPCC report suggests that climate uncertainties have significantly grown (dailymail.co.uk)

schwit1 writes: The new IPCC draft admits that the climate has not warmed as predicted and that the climate field does not know why.

They recognize the global warming ‘pause’ first reported by The Mail on Sunday last year is real – and concede that their computer models did not predict it. But they cannot explain why world average temperatures have not shown any statistically significant increase since 1997.

They admit large parts of the world were as warm as they are now for decades at a time between 950 and 1250 AD – centuries before the Industrial Revolution, and when the population and CO2 levels were both much lower.

The IPCC admits that while computer models forecast a decline in Antarctic sea ice, it has actually grown to a new record high. Again, the IPCC cannot say why.

A forecast in the 2007 report that hurricanes would become more intense has simply been dropped, without mention. This year has been one of the quietest hurricane seasons in history and the US is currently enjoying its longest-ever period – almost eight years – without a single hurricane of Category 3 or above making landfall.

Submission + - Linux 3.10 officially released (paritynews.com)

hypnosec writes: Linux 3.10 kernel has been officially released on Sunday evening which makes the 3.10-rc7 the last release candidate of the latest kernel which yields the biggest changes in years. Linus Torvalds was thinking of releasing another rc but, went against the idea and went ahead with official Linux 3.10 commit as anticipated last week. Torvalds notes in the announcement that releases since Linux 3.9 haven’t been prone to problems and 3.10 is no different. However, he added that this release could have gone either but, there was no specific reason for another rc and break the normal pattern of "rc7 is the last rc before the release."
Data Storage

Submission + - 60TB Disk Drives Could Be Reality In 2016 (computerworld.com)

CWmike writes: "The maximum areal densities of hard disk drives are expected to more than double by 2016, according to IHS iSuppli. Hard drive company Seagate has also predicted a doubling of drive density, and now IHS iSuppli is confirming what the vendor community already knew. Leading the way for greater disk density will be technologies such as heat-assisted magnetic recording (HAMR), which Seagate patented in 2006. Seagate has already said it will be able to produce a 60TB 3.5-in. hard drive by 2016. Laptop drives could reach 10TB to 20TB in the same time frame, IHS iSuppli stated. It said areal densities are projected to climb to a maximum 1,800 Gbits per square inch per platter by 2016, up from 744 Gbits per square inch in 2011. Areal density equals bit density, or bits of information per inch of a track multiplied by tracks per inch on a drive platter. From 2011 to 2016, the five-year compound annual growth rate for HDD areal densities will be equivalent to 19%, IHS iSuppli wrote in its report. This year, hard drive areal densities are estimated to reach 780Gbits per square inch per platter, and then rise to 900Gbits per square inch next year. '"The rise in areal density will pave the way for continued growth of the [hard disk drive] industry,' said Fang Zhang, an analyst for storage systems at IHS."

Submission + - New ReRam silicon chip - 100 times fast as Flash (phys.org)

bricko writes: "Dr Tony Kenyon, UCL Electronic and Electrical Engineering, said: "Our ReRAM memory chips need just a thousandth of the energy and are around a hundred times faster than standard Flash memory chips. The fact that the device can operate in ambient conditions and has a continuously variable resistance opens up a huge range of potential applications.

ReRAM chips promise significantly greater memory storage than current technology, such as the Flash memory used on USB sticks, and require much less energy and space and are also being studied for their computing capabilities."

Submission + - How Companies Learn Your Secrets

Hugh Pickens writes writes: "For decades, Target has collected vast amounts of data on every person who regularly walks into one of its stores. Now the NY Times Magazine reports on how companies like Target to identify those unique moments in consumers’ lives when their shopping habits become particularly flexible and the right advertisement or coupon can cause them to begin spending in new ways. Among life events, none are more important than the arrival of a baby and new parents are a retailer’s holy grail so in 2002, marketers at Target asked statisticians to answer an odd question: “If we wanted to figure out if a customer is pregnant, even if she didn’t want us to know, can you do that?" Specifically, the marketers said they wanted to send specially designed ads to women in their second trimester, which is when most expectant mothers begin buying all sorts of new things, like prenatal vitamins and maternity clothing. “We knew that if we could identify them in their second trimester, there’s a good chance we could capture them for years,” says statistician Andrew Pole. “As soon as we get them buying diapers from us, they’re going to start buying everything else too." As Pole’s computers crawled through the data, he was able to identify about 25 products that, when analyzed together, allowed him to assign each shopper a “pregnancy prediction” score and he soon had a list of tens of thousands of women who were most likely pregnant. About a year after Pole created his pregnancy-prediction model, a man walked into a Target outside Minneapolis and demanded to see the manager. He was clutching coupons that had been sent to his daughter, and he was angry. “My daughter got this in the mail!” he said. “She’s still in high school, and you’re sending her coupons for baby clothes and cribs? Are you trying to encourage her to get pregnant?” The manager apologized and then called a few days later to apologize again but the father was somewhat abashed. “It turns out there’s been some activities in my house I haven’t been completely aware of. She’s due in August. I owe you an apology.”"
Cellphones

Submission + - FCC: No More 'Robocalls' Unless You Agree (cnn.com)

suraj.sun writes: The FCC approved new rules Wednesday to further limit automatically dialed or prerecorded calls know as "robocalls" and automated text messages. Under the new requirements, telemarketers will have to get permission in writing before placing an automated call to a consumer. Previously, companies that had an established business relationship with a particular consumer could call them without permission.

Information calls, such as school closing information and flight cancellations, are an exception. They can be made to land-line phones without written permission. Text messages and calls to cell phones are subject to stricter rules. "Any type of phone call or text to a wireless device needs written consent," the FCC official added.

tsu doh nimh writes: A Wikileaks-style war of attrition between two competing rogue Internet pharmacy gangs has exposed some of the biggest spammers on the planet. Brian Krebs uncovers fascinating information about a hacker named "GeRa" who is supposedly behind the Grum botnet, which is currently sending about one out of every three spam emails worldwide. The story also points to several possible real-identities behind the Internet's largest spam machine.
Games

Submission + - GOG.com: numbers, controversy, outlooks and great (kingofgng.com)

KingofGnG writes: The latest weeks have probably been among the most turbulent ones in the brief history of Good Old Games: the retrogaming store has caused controversy, released “new” classic titles of the PC gaming past and has preannounced an important novelty for the product type that will soon be available on its virtual shelves. The digital delivery service created by the Polish publisher CD Projekt is in a sense victim of its own success, and of the ample trust granted by its users as an alternative channel for on-line videogame purchases.

Submission + - White House Petition to Investigate Dodd for Bribe (whitehouse.gov)

Walkingshark writes: "Chris Dodd's recent statements complaining that the congressmen the RIAA and MPAA bribed aren't staying bribed has spawned a firestorm of anger on the internet. Among the bits of fallout: a petition on the White Houses "We the People" site to investigate him, the RIAA, and the MPAA for bribery! This petition gained more than 5000 signatures in 24 hours and is still growing.

When the petition reaches 25,000 signatures the White House is obligated to respond to it in an official capacity. At that point, one way or another they will have to go on record either supporting the RIAA and MPAA or pushing them under the bus. Either way, it should be quite enlightening to see what their response is."

Submission + - Obama nominates RIAA lawyer for Solicitor General (wired.com) 1

tripleevenfall writes: Barack Obama nominated former Recording Industry Association of America lawyer Donald Verrilli Jr. on Monday to serve as the nation’s solicitor general. The solicitor general is charged with defending the government before the Supreme Court, and files friend-of-the court briefs in cases in which the government believes there is a significant legal issue. The office also determines which cases it will bring to the Supreme Court for review.

Verrilli is best known for leading the recording industry’s legal charge against music- and movie-sharing site Grokster, which ultimately led to Grokster’s demise. Until recently, Verrilli also was leading Viacom’s ongoing and flailing $1 billion copyright-infringement fight against YouTube.

Submission + - Study Analyzes Recent Grad's Unemployment by Major

Hugh Pickens writes writes: "Michelle Singletary writes that a new report from the Georgetown Center on Education and the Workforce called “Hard Times: College Majors, Unemployment and Earnings: Not All College Degrees Are Created Equal” analyzes unemployment by major and shows that not enough students — and their families who are also taking on student loans — are asking what their college major is worth in the workforce. "Too many students aren’t sure what job they could get after four, five or even six years of studying a certain major and racking up education loans," writes Singletary. "Many aren’t getting on-the-job training while they are in school or during their semester or summer breaks. As a result, questions about employment opportunities or what type of job they have the skills to attain are met with blank stares or the typical, “'I don’t know.'" The reports found that the unemployment rate for recent graduates is highest in architecture (13.9 percent) because of the collapse of the construction and home-building industry and not surprisingly, unemployment rates are generally higher in non-technical majors (PDF), such as the arts (11.1 percent), humanities and liberal arts (9.4 percent), social science (8.9 percent) and law and public policy (8.1 percent). "I wouldn’t want to discourage people from pursuing a career they love, even if the pay isn’t very high. However, that choice should be made with the understanding of which job opportunities might be available and weighing what you can expect to earn annually against the cost of taking on debt to finance your education.""
