colinneagle writes "A blog post contending that Microsoft's decision to match Apple's iPad pricing on its Surface tablet will hurt its chances in the market has brought out some negative comments from readers who seem to like the Surface tablet. I was kind of surprised by this, as I and other bloggers seem to agree that making the fully keyboard-equipped Surface tablet roughly $120 more expensive than the iPad kind of negates the purpose — to build steam by appealing to those in the market for a cheaper tablet. Also, I've yet to see an argument that justifies pricing the Surface competitively with the iPad, so I figured I would bring the question to Slashdot: Is Microsoft's pricing for the Surface tablet justified?"

derekmead writes "New evidence that the giant impact hypothesis is correct: A paper published today in Nature shares findings of a chemical analysis of Moon rocks that shows fractional differences between the makeup of the Earth and Moon that most likely were caused by the collision between Earth and a Mars-sized planet around 4.5 billion years ago. Although the two are quite similar, it's been previously shown that Moon rocks lack volatile elements, which suggests they may have evaporated during the incredibly intense heat and pressure created during an impact event. But if the hypothesis that light elements actually evaporated from Moon rocks during their formation is correct, you'd expect to find evidence of elements being layered by mass — heavier elements would condense first, and so on. That process is known as isotopic fractionation — a concept central to carbon dating — and the Washington University team's results suggest they found exactly that (abstract). They compared the blend of zinc isotopes in Moon rocks and Earth samples, and found that the Moon rocks held slightly higher proportions of heavier zinc isotopes. If the Moon was indeed once part of Earth — which has been shown by extensive modeling (PDF) — the difference in the balance of zinc profiles would most likely be explained by lighter zinc isotopes evaporating away following a collision."

beaverdownunder writes "A former police officer in the Australian state of Victoria has called on law enforcement to prosecute creators of hate pages on social media following Facebook's decision to close down a page mocking Jill Meagher, the 29-year-old Melbourne woman abducted and killed last month. Susan McLean, who spent 27 years with Victoria Police before launching her cyber safety consultancy three years ago, said police have the ability to prosecute the creators of pages that are in breach of Australian laws but appear to be unwilling to use it. 'There have been many cases in the UK where these people have been hunted down and charged and jailed. We need to do that in Australia.' Under section 474.17 of the Commonwealth Crimes Act, it is an offense to use 'a carriage service to menace, harass or cause offense,' punishable by three years in jail."

Frequent contributor Bennett Haselton writes: After I sent 10 new proxy sites to my (confirmed-opt-in) mailing list, two of them ended up on one of Spamhaus's blacklists, and as a result, all 10 domains were disabled by the domain registrar, so the sites disappeared from the Web. Did you even know this could happen?"

concealment writes with news that Amazon's Jeff Bezos has called for new legislation from governments to end abuse of the patent system. He said, 'Patents are supposed to encourage innovation and we're starting to be in a world where they might start to stifle innovation. Governments may need to look at the patent system and see if those laws need to be modified because I don't think some of these battles are healthy for society.' His comments are from an interview with the UK's Metro. Bezos was also optimistic about the future of the private space industry: "If private companies can start to generate profits from this kind of activity then you’ll start to see the flywheel spin more rapidly and we’ll make more progress, because I really do think we want to live in a civilization where millions of people are living and working in space."

Dupple sends this quote from MIT's Technology Review: "Computerized hospital equipment is increasingly vulnerable to malware infections, according to participants in a recent government panel. These infections can clog patient-monitoring equipment and other software systems, at times rendering the devices temporarily inoperable. While no injuries have been reported, the malware problem at hospitals is clearly rising nationwide, says Kevin Fu, a leading expert on medical-device security and a computer scientist at the University of Michigan and the University of Massachusetts, Amherst, who took part in the panel discussion. [He said], 'Conventional malware is rampant in hospitals because of medical devices using unpatched operating systems. There's little recourse for hospitals when a manufacturer refuses to allow OS updates or security patches.' ... Despite FDA guidance issued in 2009 to hospitals and manufacturers—encouraging them to work together and stressing that eliminating security risks does not always require regulatory review—many manufacturers interpret the fine print in other ways and don't offer updates, Fu says. And such reporting is not required unless a patient is harmed."

Hugh Pickens writes "The Christian Science Monitor reports that scientists are planning a new route for NASA's New Horizons space probe as it approaches a potentially perilous path toward Pluto through a possible set of rings that may create dangerous debris zones for the NASA spacecraft. New Horizons is currently about 1,000 days away and 730 million miles from closest approach to Pluto but given that New Horizons is currently zooming away from the sun at more than 33,500 mph, 'a collision with a single pebble, or even a millimeter-sized grain, could cripple or destroy New Horizons,' says project scientist Hal Weaver. 'We need to steer clear of any debris zones around Pluto.' Researchers are making plans to avoid these hazards if New Horizons needs to. 'We are now exploring nine other options, "bail-out trajectories,"' says principal investigator Alan Stern. New Horizon's current plan would take it about halfway between Pluto and the orbit of its largest moon, Charon. Four of the bail-out trajectories would still take the spacecraft between Pluto and Charon's orbit. The other alternatives would take New Horizons much further away from Pluto, past the orbits of its known moons. 'If you fly twice as far away, your camera does half as well; if it's 10 times as far, it does one-tenth as well,' says Stern. 'Still, half a loaf is better than no loaf. Sending New Horizons on a suicide mission does no one any good. We're very much of the mind to accomplish as much as we can, and not losing it all recklessly. Better to turn an A+ to an A- than get an F by overreaching.'"

I recently sat down with Chris DiBona to talk about the 15th anniversary of Slashdot. In addition to discussing the joys of heading an email campaign against spamming politicians, and the perils of throwing a co-worker's phone into a bucket, even if you think that bucket is empty, we talked about the growth of Google Summer of Code. Below you'll find his story of how a conversation about trying to get kids to be more active with computers in the summer has led to the release of 55 million lines of code.

Via the H comes news of a possible remote attack vector using the protocol handler installed by Valve's Steam platform: "During installation, it registers the steam:// URL protocol which is capable of connecting to game servers and launching games ... In the simplest case, an attacker can use this to interfere with the parameters that are submitted to the program. For example, the Source engine's command line allows users to select a specific log file and add items to it. The ReVuln researchers say that they successfully used this attack vector to infect a system (PDF) via a batch file that they had created in the autostart folder. ... In the even more popular Unreal engine, the researchers also found a way to inject and execute arbitrary code. Potential attackers would, of course, first have to establish which games are installed on the target computer. "

Ollabelle writes "David Bernstein, a nonprofit executive who lives in Gaithersburg, Md., has two sons, ages 7 and 15. He has previously written about how schools fail students with Attention Deficit Hyperactivity Disorder. Now he turns his attention to mandated curriculum in public schools, and argues that his sons shouldn't be forced to take any science class." From the article: "There’s a concept in economics called 'opportunity costs,' which you may not have learned about because you were taking chemistry instead of economics. Opportunity costs are the sacrifices we make when we choose one alternative over another. ... When you force my son to take chemistry (and several other subjects, this is not only about chemistry), you are not allowing him that same time to take a public speaking course, which he could be really good at, or music, or political science, or creative writing, or HTML coding for websites."

Zothecula writes "Video game developers are always looking for new ways to give players a more immersive experience. But with several motion-controlled systems widely available and a viable virtual reality headset in the works, what else could be done to make games seem more realistic? Sony may have an unexpected answer with a recent patent that describes a controller that changes temperature between hot and cold to match in-game actions. With the controller giving 'temperature feedback,' the idea is that players would be able to more closely feel what their character feels, from getting hit with a fireball to traveling through a blizzard."

An anonymous reader writes "Boxee has announced the game-changing Boxee TV, offering live streaming TV via two on-board tuners and an industry-first 'No Limit' DVR service that allows users to record as much TV content as they want, and access it from virtually anywhere. The problem is that the unit, which records directly to the cloud, does not allow recording to a local drive, meaning users are stuck with Boxee for as long as they want to access their stored content — potentially hundreds or thousands of hours – to the tune of $14.99 per month until Boxee ups the ante. CEPro.com suggests, 'I suspect Boxee is offering unlimited storage to make users especially beholden to them. The more content you have, the less likely you are to drop the service.'"
