How the Militarization of the Internet is Changing Warfare 204

Posted by samzenpus from the you've-got-war-mail dept.
puddingebola writes in with a link to a New York Times article about how the militarization of the internet is changing contemporary warfare. "The decision by the United States and Israel to develop and then deploy the Stuxnet computer worm against an Iranian nuclear facility late in George W. Bush's presidency marked a significant and dangerous turning point in the gradual militarization of the Internet. Washington has begun to cross the Rubicon. If it continues, contemporary warfare will change fundamentally as we move into hazardous and uncharted territory. It is one thing to write viruses and lock them away safely for future use should circumstances dictate it. It is quite another to deploy them in peacetime. Stuxnet has effectively fired the starting gun in a new arms race that is very likely to lead to the spread of similar and still more powerful offensive cyber-weaponry across the Internet. Unlike nuclear or chemical weapons, however, countries are developing cyber-weapons outside any regulatory framework."

Gamera II Team Smashes Previous Best Human-Powered Helicopter Flight Time 118

Posted by samzenpus from the pedal-faster dept.
Zothecula writes "For over 30 years, the $250,000 for the American Helicopter Society's Igor I. Sikorsky Human Powered Helicopter Competition prize has looked decidedly secure, but Gamera II has changed all that. Last week, Clark School of Engineering team pilots came close to breaking one of the competition's major milestones. Ph.D. candidate from Kyle Gluesenkamp from the School's mechanical engineering department, hand-cranking and pedaling like his life depended on it, managed to keep the huge quad-rotor craft aloft for 50 seconds, an impressive new world record that's currently awaiting validation by the National Aeronautic Association (NAA)." We previously covered their attempt to break the record last May.

Jimmy Wales Calls UK Government To Halt O'Dwyer Extradition 94

Posted by samzenpus from the keeping-it-in-house dept.
judgecorp writes "Wikipedia founder Jimmy Wales has called on the UK government to stop the extradition of Richard O'Dwyer. O'Dwyer was accused of infringing copyright with his site TVShack, but charges were dismissed in the UK. Wales has set up a petition and calls this the start of a new 'Internet war' following the successful opposition to SOPA earlier this year."

Are We Failing To Prepare Children For Leadership In the US? 754

Posted by samzenpus from the growing-up-fast dept.
Vulcan195 writes "Would you let your three-year-old play with a real saw? You would if you were a parent in Switzerland. Suzanne Lucas (a U.S. mom residing in Switzerland) writes about the contrasts between the U.S. and Swiss ways of instilling wisdom. She writes: 'Every Friday, whether rain, shine, snow, or heat, my three-year-old goes into the forest for four hours with 10 other school children. In addition to playing with saws and files, they roast their own hot dogs over an open fire. If a child drops a hot dog, the teacher picks it up, brushes the dirt off, and hands it back.' She suggests that such kids grow up and lead the ones who were coddled (e.g. U.S. kids) during their early years."

"Twisted" OAM Beams Carry 2.5 Terabits Per Second 142

Posted by samzenpus from the greased-lightning dept.
MrSeb writes "American and Israeli researchers have used twisted, vortex beams to transmit data at 2.5 terabits per second. As far as I can discern, this is the fastest wireless network ever created — by some margin. These twisted signals use orbital angular momentum (OAM) to cram much more data into a single stream, without using more spectrum. In current state-of-the-art transmission protocols (WiFi, LTE, COFDM), we only modulate the spin angular momentum (SAM) of radio waves, not the OAM. If you picture the Earth, SAM is our planet spinning on its axis, while OAM is our movement around the Sun. Basically, the breakthrough here is that researchers have created a wireless network protocol that uses both OAM and SAM. In this case, Alan Willner and fellow researchers from the University of Southern California, NASA's Jet Propulsion Laboratory, and Tel Aviv University, twisted together eight ~300Gbps visible light data streams using OAM. For the networking nerds, Willner's OAM link has a spectral efficiency of 95.7 bits per hertz; LTE maxes out at 16.32 bits/Hz; 802.11n is 2.4 bits/Hz. Digital TV (DVB-T) is just 0.55 bits/Hz. In short, this might just be exactly what our congested wireless spectrum needs."

Tech Manufacturing Is a Disaster Waiting To Happen 224

Posted by timothy from the to-be-fair-so-is-everything-else dept.
Hugh Pickens writes "Peter Cochrane writes that since globalization took hold, geographic diversity has become distorted along with the resilience of supply so we now have a concentration of limited sourcing and manufacture in the supply chain in just one geographic region, south-east Asia, amounting to a major disaster just waiting to happen. 'Examples of a growing supply-chain brittleness include manufacturers temporarily denuded of LCD screens, memory chips and batteries by fires, a tsunami, and industrial problems,' writes Cochrane. 'With only a few plants located in south-east Asia, we are running the gauntlet of man-made and natural disasters.' Today, PCs, laptops, tablets and smartphones are produced by just 10 dominant contract manufacturers, spearheaded by Foxconn of Taiwan — which manufactures for Apple, Dell, HP, Acer, Sony, Nokia, Intel, Cisco, Nintendo and Amazon among others. The bad news is that many of the 10 big players in the IT field are not making good profits, so economic pressure could result in the 10 becoming seven."

Sonic.net's CEO On Why ISPs Should Only Keep User Logs Two Weeks 190

Posted by timothy from the privacy-has-value dept.
Sparrowvsrevolution writes "Dane Jasper's tiny Internet service provider Sonic.net briefly took the national spotlight last October, when it contested a Department of Justice order that it secretly hand over the data of privacy activist and WikiLeaks associate Jacob Appelbaum. But Sonic.net has actually been quietly implementing a much more fundamental privacy measure: For the past eighteen months it's only kept logs of user data for two weeks before deletion, compared with 18 to 36 months at Verizon, AT&T, Comcast, Time Warner and other ISPs. In a lengthy Q&A, he explains how he came to the decision to limit logging after a series of shakedowns by copyright lawyers attempting to embarrass users who had downloaded porn films, and he argues that it's time all ISPs adopt the two-week rule."

Ask Slashdot: Jobs For Geeks In the Business/Financial World? 181

Posted by timothy from the do-your-best-gordon-gecko-impression dept.
First time accepted submitter menphix writes "Hi there! I'm a software engineer in the bay area. I will be moving to Hong Kong where my wife works shortly. I understand that there will be a lot less opportunities to work for software companies there than in the bay area, but they do have a lot of business/financial companies in HK: investment banking, private equity, hedge funds, you name it! So I'm thinking maybe it'll be easier if I transition to work for those companies. Since I got my B.S. and M.S. both in computer science, I have no idea what those 'Wall Street jobs' are like, so I'm just wondering what you guys know about jobs in the business/financial world for geeks? Has anybody made the jump before?"

Nintendo's Big-Screen 3DS XL Meets Lukewarm Reception 192

Posted by timothy from the will-need-a-new-set-of-pants dept.
MojoKid writes "Nintendo took the wraps off its new, super-sized 3DS XL handheld on Friday, but reactions have been anything but enthusiastic. The new DS offers a larger set of screens (4.88 inches top / 4.18" bottom), better battery life, and will ship with a copy of New Super Marios 2 but it's launching into a very different market than what the original DS XL faced in 2009. The 3DS XL's battery improvements aren't just icing on the cake — they're seen as remedying a critical problem with the current handheld. It also won't support the second circle pad added by the Circle Pad Pro, which implies Nintendo is ready to kill that peripheral altogether. The other major problem is that a larger screen isn't really what the 3DS needed in order to be more successful."

jfruh writes "AT&T's video library is a treasure trove of future-looking films from the past, and this one is no exception. Combining what might be the first on-film use of the phrase 'information superhighway' with predictions of Siri-like services and sweet '80s computer graphics, this offers a valuable look at how close we came to our past's future."

MemSQL Makers Say They've Created the Fastest Database On the Planet 377

Posted by timothy from the before-you-even-think-it dept.
mikejuk writes "Two former Facebook developers have created a new database that they say is the world's fastest and it is MySQL compatible. According to Eric Frenkiel and Nikita Shamgunov, MemSQL, the database they have developed over the past year, is thirty times faster than conventional disk-based databases. MemSQL has put together a video showing MySQL versus MemSQL carrying out a sequence of queries, in which MySQL performs at around 3,500 queries per second, while MemSQL achieves around 80,000 queries per second. The documentation says that MemSQL writes back to disk/SSD as soon as the transaction is acknowledged in memory, and that using a combination of write-ahead logging and snapshotting ensures your data is secure. There is a free version but so far how much a full version will cost isn't given." (See also this article at SlashBI.)

Teaching Natural Sciences To Social Science Students? 265

Posted by timothy from the use-lots-of-food-and-rent-analogies dept.
An anonymous reader writes "As a calculus professor for a small undergraduate institution, I normally lecture students who are majoring in the natural (or 'hard') sciences, such as mathematics, physics, and computer science. In fact, I have done so for almost thirteen years. However, for the first time this fall semester, we have a shortage of professors on our hands. As a result of this, I have been asked to teach a general education statistics class. Such classes are a major requirement for the large psychology student body we have here. I have never lectured social science students in any mathematics-related classes. My question to the Slashdot community is as follows: What are your experiences with teaching natural science classes to social science students? How is the experience the same or different in comparison to natural science students who may be more adept to the nuances of mathematics and other similar fields?"

Georgia Apple Store Refuses To Sell iPad To Iranian-American Teen 1116

Posted by timothy from the cultural-profiling dept.
pdclarry writes "An Iranian-American teenager was told by an Apple store employee that they could not sell her an iPad because it would violate U.S. trade restrictions. She returned to the store with a camera crew from a local TV station and was again turned down. Apparently an Apple employee heard her speaking Farsi. As he was also of Iranian extraction he recognized the language and used this as a basis for refusal."
