Euler's Partition Function Theory Finished 117

Posted by Soulskill on Friday January 21, 2011 @05:29PM from the that-was-quick dept.

universegeek writes "Mathematician Ken Ono, from Emory, has solved a 250-year-old problem: how to exactly and explicitly generate partition numbers. Ono and colleagues were able to finally do this by realizing that the pattern of partition numbers is fractal (PDF). This pattern allowed them to find a finite, algebraic formula, which is like striking oil in mathematics."

Gamer Plays Doom For the First Time 362

Posted by Soulskill on Monday August 09, 2010 @10:42PM from the new-is-relative dept.

sfraggle writes "Kotaku has an interesting review of Doom (the original!) by Stephen Totilo, a gamer and FPS player who, until a few days ago, had gone through the game's 17-year history without playing it. He describes some of his first impressions, the surprises that he encountered, and how the game compares to modern FPSes. Quoting: 'Virtual shotgun armed, I was finally going to play Doom for real. A second later, I understood the allure the video game weapon has had. In Doom the shotgun feels mighty, at least partially I believe because they make first-timers like me wait for it. The creators make us sweat until we have it in hand. But once we have the shotgun, its big shots and its slow, fetishized reload are the floored-accelerator-pedal stuff of macho fantasy. The shotgun is, in all senses, instant puberty, which is to say, delicately, that to obtain it is to have the assumed added potency that a boy believes a man possesses vis a vis a world on which he'd like to have some impact. The shotgun is the punch in the face the once-scrawny boy on the beach gives the bully when he returns a muscled linebacker.'"

Two Unpatched Flaws Show Up In Apple iOS 171

Posted by samzenpus on Wednesday August 04, 2010 @07:55PM from the rotten-apple dept.

Trailrunner7 writes "The technique that the Jailbreakme.com Web site is using to bypass the iPhone's security mechanisms and enable users to run unapproved apps on their phones involves exploiting two separate vulnerabilities. One of the vulnerabilities is a memory-corruption flaw that affects the way that Apple's mobile devices, including the iPad and iPod Touch, display PDFs. The second weakness is a problem in the Apple iOS kernel that gives an attacker higher privileges once his code is on a targeted device, enabling him to break out of the iOS sandbox. The combination of the two vulnerabilities — both of which are unpatched at the moment — gives an attacker the ability to run remote code on the device and evade the security protections on the iPhone, iPad or iPod Touch. The technique became public earlier this week when the Jailbreakme.com site began hosting a set of specially crafted PDF files designed to help users jailbreak their Apple devices and load apps other than the ones approved by Apple and offered in its official App Store."

Cassandra and Voldemort Benchmarked 45

Posted by timothy on Saturday May 08, 2010 @02:02PM from the rifling-the-file-cabinet dept.

kreide33 writes "Key/Value storage systems are gaining in popularity, much because of features such as easy scalability and automatic replication. However, there are several to choose from and performance is an important deciding factor. This article compares the performance of two of the most well-known projects, Cassandra and Voldemort, using several different mixes of access types, and compares both throughput and latency."

Games Workshop Sues Warhammer Online Fansite 182

Posted by Soulskill on Saturday May 08, 2010 @12:53PM from the don't-anger-your-base-again dept.

chalkyj writes "WarhammerAlliance.com (run for the last five years as one of the leading fansites for the MMORPG Warhammer Online) is being sued by Games Workshop for the use of the 'Warhammer' name, 'cybersquatting' and 'unfair competition.' This lawsuit is yet another in Games Workshop's disturbing pattern of suing their fans and hobbyists, this time going after a legitimate fansite for their MMORPG franchise. The full complaint (PDF) has been posted online."

St. Louis Museum Offers Thrills, Chills, and Lawsuits 140

Posted by samzenpus on Monday May 03, 2010 @02:53PM from the everything-fun-is-dangerous dept.

theodp writes "Despite the whiff of danger, or perhaps because of it, the WSJ reports that the City Museum is one of St. Louis's most popular attractions. Housed in a 10-story brick building, the City Museum shows none of the restraint or quiet typical of most museums. It boasts a five-story jungle gym with two real-life jets kids can climb on, an enclosed Monster Slide that drops riders the length of three staircases, and a rooftop Ferris wheel. Sure, there are the occasional severed fingers and skull fractures, but museum founder Bob Cassilly contends that it is as safe as it can be without being a bore. 'They [lawyers] are taking the fun out of life,' says Cassilly, adding that 'when you have millions of people do something, something's going to happen no matter what you do.'"

Japanese Researchers Make Plastic Out of Water 117

Posted by timothy on Friday April 30, 2010 @07:22PM from the what's-kanji-for-boffin? dept.

greenrainbow writes with this excerpt from Inhabit: "The material shown in the picture above is just ice, right? Look again. Elastic water, a new substance invented by researchers at Tokyo University, is a jelly-like substance made up of 95% water along with two grams of clay and a small amount of organic materials. As is, the all-natural substance is perfect for medical procedures, because it's made of water, poses no harm to people, and is perfect for mending tissue. And, if the research team can increase the density of this exciting new substance, it could be used in place of our current oil-based plastics for a host of other things."

EA Shutting Down Video Game Servers Prematurely 341

Posted by Soulskill on Wednesday January 06, 2010 @07:42AM from the sixty-dollar-yearly-fee dept.

Spacezilla writes "EA is dropping the bomb on a number of their video game servers, shutting down the online fun for many of their Xbox 360, PC and PlayStation 3 games. Not only is the inclusion of PS3 and Xbox 360 titles odd, the date the games were released is even more surprising. Yes, Madden 07 and 08 are included in the shutdown... but Madden 09 on all consoles as well?"

Alaskan Blob Is an Algae Bloom 130

Posted by timothy on Monday July 20, 2009 @10:11AM from the no-sixes-here-just-a-couple-of-nines dept.

Bryan Gividen writes "Time.com is running a story on the previously unidentified blob floating off of the coast of Alaska. The article states that the blob is an algae bloom — far less sinister (or exciting) than any The Thing or The Blob comparison that was jokingly made. From the article: '"It's sort of like a swimming pool that hasn't been cleaned in a while." The blob, Konar said, is a microalgae made up of 'billions and billions of individuals.'"

Is Battery-Free 2-Factor ID Secure? 180

Posted by timothy on Monday July 20, 2009 @09:50AM from the go-ahead-do-your-worst dept.

An anonymous reader writes "There was a television program in Australia last week about Matthew Walker's visual battery-less two-factor authentication system called PassWindow. Essentially, you hold the clear plastic window up to the apparently random pattern on the screen of your computer, revealing a one-time PIN to type in for authentication. The plastic window has many advantages: difficult to copy or view over the shoulder, etc. Because there is no electronics, chip or battery, the PassWindow is extremely cheap to manufacture, giving it a big advantage over other two-factor authentication systems. However, I don't know about the security of the system. The apparently random pattern of lines in the PassWindow is analogous to a one-time pad, using a different subset of the one-time pad every time a PIN is needed. Is this a useful level of security for logging in to a bank account?"

Tiniest Lamp Spans Quantum, Classical Physics 59

Posted by kdawson on Friday May 01, 2009 @10:21AM from the just-small-enough dept.

Urchin writes "Physicists in California have made the smallest ever incandescent lamp using a carbon nanotube as the filament. The nanotube is so small it behaves as a quantum mechanical system but it's just large enough that the classical physics rules of thermodynamics should apply. Analyzing the light emitted from the tiny light will give the team a better picture of what happens in the twilight zone between the quantum and classical worlds." The New Scientist article doesn't mention the researchers' surprise, as the abstract does: "Remarkably, the heat equation and Planck's law together give a precise, quantitative description of the light intensity as a function of input power, even though the nanotube's small size places it outside the thermodynamic limit."

Comment Damned Tech Illiterates (Score 1) 853

Whatever the merits of Sodomsky's tastes, what got me was this portion of the court's opinion: "[T]he playing of videos already in the computer was a manner of ensuring that the burner was functioning properly." It's hard to tell who's the bigger idiot here, the CC employee for thinking that playing files off the hard drive would verify the operation of a DVD drive, or the court for accepting that kind of crap!
