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."

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."

lukehopewell1 writes "Days out from Google's I/O conference, training documents have been issued to resellers all over the world detailing Google's new Nexus tablet. It's a 7-inch device with an optimized Tegra 3 chip inside and it's going to be the first device to run Jelly Bean, the new version of Android, that, among other notable features, will see Google manage device updates. The device will be priced at $US199 and is aimed as a direct competitor to Amazon's Kindle Fire."

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."

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."

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?"

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."

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.)

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?"

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."

Freshly Exhumed writes "Danny Sullivan over at Marketing Land has been tipped over the edge by various colleagues: 'After seeing yet another "hands-on" review of the Microsoft Surface tablet, I thought it would be interesting to shed more light on what exactly the journalists who assembled in Hollywood this week for the Surface launch event actually got to do with the tablets. In short, not a lot. Come along as I explain the hands-off reality of what I saw.' In response to Sullivan's criticisms, TechRadar contributor Mary To Many rebuts that merely touching something that does not operate nor even truly exist equates to an actual hands-on review. So, what do Slashdotters expect a "hands-on" review to reveal and/or include?"

First time accepted submitter scottbee writes "A major New York intellectual property lawfirm has filed a $1m lawsuit against domain squatter/security researcher Wesley Kenzie (aka Securikai). Kenzie registered domain names to collect misaddressed email, and then holding companies to ransom claiming he had found security vulnerabilities and would consult for five figure engagements. Lockheed Martin handled it with a simple UDRP, but the Gioconda Law Group decided instead to file a lawsuit for 'cybersquatting, trademark infringement and unlawful interception of a law firm's private electronic communications in violation of federal laws,' along with a permanent injunction. Kenzie had also tried the same tactic against Rapid7's HDMoore, but was shamed out of the domain names earlier this year."

That Alan Turing committed suicide is widely accepted as fact. Now, an anonymous reader writes, "According to Professor Jack Copeland, director of the The Turing Archive for the History of Computing, 'The coroner [in Turing's case] didn't really investigate the evidence at all, he just jumped to the conclusion that he committed suicide. He seems to have been very biased from the statements in newspapers at the time.' Copeland further said that medical evidence suggested Turing died from inhaling cyanide rather than drinking or ingesting it."

According to this Reuters report, RIM is considering separating its messaging network business from its manufacture of handsets, and either listing the resulting new company separately, or selling it to another firm. According to the article, "Potential buyers would include Amazon and Facebook, it reported, adding that RIM's messaging network could also be sold, or opened up to rivals such as Apple and Google to generate income. An alternative option would be to keep the company together but sell a stake to a larger technology firm such as Microsoft."
