ccktech writes "As reported by NPR and Chemistry world, the journal Science has a paper by David Ehre, Etay Lavert, Meir Lahav, and Igor Lubomirsky [note: abstract online; payment required to read the full paper] of Israel's Weizmann Institute, who have figured out a way to freeze pure water by warming it up. The trick is that pure water has different freezing points depending on the electrical charge of the surface it resides on. They found out that a negatively charged surface causes water to freeze at a lower temperature than a positively charged surface. By putting water on the pyroelectric material Lithium Tantalate, which has a negative charge when cooler but a positive change when warmer; water would remain a liquid down to -17 degrees C., and then freeze when the substrate and water were warmed up and the charge changed to positive, where water freezes at -7 degrees C."

An anonymous reader writes "One of the basic utilities supplied with any operating system is a desktop calculator. These are often simple utilities that are perfectly adequate for basic use. They typically include trigonometric functions, logarithms, factorials, parentheses and a memory function. However, the calculators featured in this article are significantly more sophisticated with the ability to process difficult mathematical functions, to plot graphs in 2D and 3D, and much more. Occasionally, the calculator tool provided with an operating system did not engender any confidence. The classic example being the calculator shipped with Windows 3.1 which could not even reliably subtract two numbers. Rest assured, the calculators listed below are of precision quality."

The Escapist's Shamus Young recently posted an article complaining about the proliferation of distribution platforms and social networks for video games. None of the companies who make these are "quite sure how games will be sold and played ten years from now," he writes, "but they all know they want to be the ones running the community or selling the titles." Young continues, "Remember how these systems usually work: The program sets itself up to run when Windows starts, and it must be running if you want to play the game. If you follow this scheme to its logical conclusion, you'll see that the system tray of every gaming PC would eventually end up clogged with loaders, patchers, helpers, and monitors. Every publisher would have a program for serving up content, connecting players, managing digital licenses, performing patches, and (most importantly) selling stuff. Some people don't mind having 'just one more' program running in the background. But what happens when you have programs from Valve, Stardock, Activision, 2k Games, Take-Two, Codemasters, Microsoft, Eidos, and Ubisoft? Sure, you could disable them. But then when you fire the thing up to play a game, it will want to spend fifteen minutes patching itself and the game before it will let you in. And imagine how fun it would be juggling accounts for all of them."

An anonymous reader writes "For years, Microsoft has allowed Visual Studio users to define arbitrary tab widths, often to the dismay of those viewing the resultant code in other editors. With VS 2010, it appears that they have taken the next step of forcing tab width to be the same as the indent size in code. Two-space tabs anyone?"

Trailrunner7 writes with this snippet from ThreatPost: "Apple's first Mac OS X security update for 2010 is out, providing cover for at least 12 serious vulnerabilities. The update, rated critical, plugs security holes that could lead to code execution vulnerabilities if a Mac user is tricked into opening audio files or surfing to a rigged Web site."

Theosis sends word that an astronomer at the University of Rochester and his colleagues have made the surprise discovery that Alcor, one of the brightest stars in the Big Dipper, is actually two stars; and it is apparently gravitationally bound to the four-star Mizar system, making the whole group a sextuplet. This would make the Mizar-Alcor sextuplet the second-nearest such system known. The discovery is especially surprising because Alcor is one of the most studied stars in the sky. The Mizar-Alcor system has been involved in many "firsts" in the history of astronomy: "Benedetto Castelli, Galileo's protege and collaborator, first observed with a telescope that Mizar was not a single star in 1617, and Galileo observed it a week after hearing about this from Castelli, and noted it in his notebooks... Those two stars, called Mizar A and Mizar B, together with Alcor, in 1857 became the first binary stars ever photographed through a telescope. In 1890, Mizar A was discovered to itself be a binary, being the first binary to be discovered using spectroscopy. In 1908, spectroscopy revealed that Mizar B was also a pair of stars, making the group the first-known quintuple star system."

An anonymous reader writes "A team at NIST (the National Institute of Standards and Technology) used berylium ions, lasers and electrodes to develop a quantum system that performed 160 randomly chosen routines. Other quantum systems to date have only been able to perform single, prescribed tasks. Other researchers say the system could be scaled up. 'The researchers ran each program 900 times. On average, the quantum computer operated accurately 79 percent of the time, the team reported in their paper.'"

Harry writes "For every blockbuster of the mouse world (such as Microsoft and Logitech's big sellers) there have been countless mice that flopped, or never made it to market. Mice shaped like pyramids; mice shaped like Mickey; mice that doubled as numeric keypads or phones. Even one that sat on your steering wheel. I've rounded up some evocative patent drawings on twenty notable examples."

snydeq writes to recommend Peter Wayner's inside look at the frustration iPhone developers face from Apple when attempting to distribute their apps through the iPhone App Store. Wayner's long piece is an extended analogy comparing Apple to the worst of Soviet-era bureaucracy. "Determined simply to dump an HTML version of his book into UIWebView and offer two versions through the App Store, Wayner endures four months of inexplicable silences, mixed messages, and almost whimsical rejections from Apple — the kind of frustration and uncertainty Wayner believes is fast transforming Apple's regulated marketplace into a hotbed of bottom-feeding mediocrity. 'Developers are afraid to risk serious development time on the platform as long as anonymous gatekeepers are able to delay projects by weeks and months with some seemingly random flick of a finger,' Wayner writes of his experience. 'It's one thing to delay a homebrew project like mine, but it's another thing to shut down a team of developers burning real cash. Apple should be worried when real programmers shrug off the rejections by saying, "It's just a hobby."'"

We're emerging from the longest, deepest sunspot drought since 1913 (we discussed its depths here) with the appearance of a robust group of sunspots over the weekend. Recently we discussed a possible explanation for the prolonged minimum. The Fox News article quotes observer Michael Buxton of Ocean Beach, Calif.: "This is the best sunspot I've seen in two years." jamie found a NASA site where you can generate a movie of the recent sunspot's movement — try selecting the first image type and bumping the resolution to 1024. The magnetic field lines are clearly visible.

Midnight Thunder writes "I have spent the past six months working on a software project, and while I can come up with ideas, I just can't seem to sit down in front of the computer to code. I sit there and I just can't concentrate. I don't know whether this is akin to writer's block, but it feels like it. Have any other Slashdotters run into this and if so how did you get out of it? It is bothering me since the project has ground to a halt and I really want to get started again. I am the sole developer on the project, if that makes a difference."

incognito84 writes "The development team responsible for the creation of the freeware game America's Army 3 has been canned, days after the launch of the highly flawed game, which was distributed mostly via Steam. 'The anonymous America's Army 3 developers in touch with Kotaku unsurprisingly didn't sound too pleased with the current situation, venting that "a lot of good people [worked] insanely long hours on this game that was butchered by outside sources.' The game's launch was plagued by massive server authentication issues which inhibited most players from playing it even two days afterward. One of the developers made a post on the official forums saying they were 'effectively stabbed in the back,' and that much of the funding was filtered to the bureaucracy. A patch has been released to address some of the game's issues."

mikesd81 writes "Wired.com reports that you may not know it, but if you have a wireless router, a cordless phone, remote car-door opener, baby monitor or cellphone in your house, the FCC claims the right to enter your home without a warrant at any time of the day or night in order to inspect it. FCC spokesman David Fiske says 'Anything using RF energy — we have the right to inspect it to make sure it is not causing interference.' The FCC claims it derives its warrantless search power from the Communications Act of 1934, though the constitutionality of the claim has gone untested in the courts. 'It is a major stretch beyond case law to assert that authority with respect to a private home, which is at the heart of the Fourth Amendment's protection against unreasonable search and seizure,' says Electronic Frontier Foundation lawyer Lee Tien. 'When it is a private home and when you are talking about an over-powered Wi-Fi antenna — the idea they could just go in is honestly quite bizarre.'"
