Virtual Telescope Zooms In On Milky Way Black Hole

septembre 4, 2008 · Filed Under Slashdot · Comment 

FiReaNGeL writes “An international team has obtained the closest views ever of what is believed to be a super-massive black hole at the center of the Milky Way galaxy. The astronomers used radio dishes in Hawaii, Arizona and California to create a virtual telescope more than 2,800 miles across that is capable of seeing details more than 1,000 times finer than the Hubble Space Telescope. The target of the observations was the source known as Sagittarius A* (”A-star”), long thought to mark the position of a black hole whose mass is 4 million times greater than the sun. Though Sagittarius A* was discovered 30 years ago, the new observations for the first time have an angular resolution, or ability to observe small details, that is matched to the size of the event horizon.”

Heavy Rain - Playing a Story

septembre 4, 2008 · Filed Under Slashdot · Comment 

Edge Magazine is running a piece about Heavy Rain, a thriller by Quantic Dream that’s been in development for a few years now. Edge spoke with David Cage, the game’s writer and director, about using graphics technology not simply for breathtaking landscapes or realistic lighting, but to bring the characters to life and make them more believable. Cage walked the folks at Kotaku through a demo, and they provided details on how the controls will work. From Edge: “‘We worked very hard on motion capture, especially facial motion capture,’ explains Cage. ‘As you know, eyes are incredibly hard to do: the minute movements they constantly make mean you can tell whether something is human or not. We created a technology to motion-capture that from actors.’ The shaders applied to the lead character’s eyes and the skin that surrounds them also conspire to nudge Heavy Rain’s characters closer to believability. The ‘deadness’ that so often afflicts such digital mannequins has been significantly chipped away, and we are presented with Madison, a character whose facial features, though attractive in an expectedly unnatural sort of way, also carry blemishes that succeed in breaking down her artificiality.”

$208 Million Petascale Computer Gets Green Light

septembre 4, 2008 · Filed Under Slashdot · Comment 

coondoggie writes “The 200,000 processor core system known as Blue Waters got the green light recently as the University of Illinois at Urbana-Champaign and its National Center for Supercomputing Applications (NCSA) said it has finalized the contract with IBM to build the world’s first sustained petascale computational system. Blue Waters is expected to deliver sustained performance of more than one petaflop on many real-world scientific and engineering applications. A petaflop equals about 1 quadrillion calculations per second. They will be coupled to more than a petabyte of memory and more than 10 petabytes of disk storage. All of that memory and storage will be globally addressable, meaning that processors will be able to share data from a single pool exceptionally quickly, researchers said. Blue Waters, is supported by a $208 million grant from the National Science Foundation and will come online in 2011.”

Physicists Discover “Doubly Strange” Particle

septembre 4, 2008 · Filed Under Slashdot · Comment 

Tsalg writes “Physicists have discovered a new particle made of three quarks, the Omega-sub-b. The particle contains two strange quarks and a bottom quark (s-s-b). It is an exotic relative of the much more common proton and weighs about six times the proton mass. This is probably one of the last noticeable sub-atomic discoveries made somewhere else than at CERN since LHC is about to start the hunt for the Higgs particle that remains elusive even for the experiment that just discovered the Omega-sub-b..”

Huge Arctic Ice Shelf Breaks Off

septembre 4, 2008 · Filed Under Slashdot · Comment 

knarfling writes “CNN is reporting that a chunk of ice shelf nearly the size of Manhattan has broken away from Ellesmere Island in Canada’s northern Arctic. Just last month 21 square miles of ice broke free from the Markham Ice Shelf. Scientists are saying that Ellesmere Island has now lost more than 10 times the ice that was predicted earlier this summer. How long before the fabled Northwest Passage is a reality?”

The 5 Most Laughable Terms of Service On the Net

septembre 4, 2008 · Filed Under Slashdot · Comment 

nicholas.m.carlson writes “According to these five terms of service and EULA, Google owns any content you create using its Chrome browser and can filter your Gmail messages if it likes. Facebook says it can sell its users’ uploaded images as stock photography. YouTube can keep footage of your kids forever, even after you’ve deleted it from the site. And AOL can ban you for using vulgar language on AIM. Funny, right? That’s why Valleywag calls them ‘The 5 most laughable terms of service on the Net.’” Reader dlaudel writes, regarding the previously-mentioned Google EULA for Chrome, “According to Ars Technica, Google’s EULA for Chrome was just copy-and-pasted from its EULA for other services, a practice that is apparently common at Google.”

Dolphin Inspired Mini-sub

septembre 4, 2008 · Filed Under Slashdot · Comment 

What do you get the millionaire in your life who has everything? How about the Seabreacher mini-sub. Described as a dolphin-inspired cross between a jet ski and a submarine, the Seabreacher has a top speed of 45mph above the waves and 20mph below them. The two-man £30,000 craft is 15′ long and its design makes it self-righting. Strangely, this doesn’t come with a laser package.

Chrome Vs. IE 8

septembre 4, 2008 · Filed Under Slashdot · Comment 

snydeq writes “Google Chrome and Internet Explorer 8 herald a new, resource-intensive era in Web browsing, one sure to shift our conception of acceptable minimum system requirements, InfoWorld’s Randall Kennedy concludes in his head-to-head comparison of the recently announced multi-process, tabbed browsers. Whereas single-process browsers such as Firefox aim for lean, efficient browsing experiences, Chrome and IE 8 are all about delivering a robust platform for reliably running multiple Web apps in a tabbed format in answer to the Web’s evolving needs. To do this, Chrome takes a ‘purist’ approach, launching multiple, discrete processes to isolate and protect each tab’s contents. IE 8, on the other hand, goes hybrid, creating multiple instances of the iexplore.exe process without specifically assigning each tab to its own instance. ‘Google’s purist approach will ultimately prove more robust,’ Kennedy argues, ‘but at a cost in terms of resource consumption.’ At what cost? Kennedy’s comparison found Chrome ‘out-bloated’ IE 8, consuming an average of 267MB vs. IE 8’s 211MB. This, and recent indications that IE 8 itself consumes more resources than Vista, surely announce a new, very demanding era in Web-centric computing.”

Criminals Remote-Wiping Cell Phones

septembre 4, 2008 · Filed Under Slashdot · Comment 

An anonymous reader writes “Crafty criminals are increasingly using the remote wipe feature on the Apple iPhone and other business handsets, such as RIM’s BlackBerry, to destroy incriminating evidence, the head of the UK’s Serious Fraud Office Keith Foggon has warned. Foggon told silicon.com that the move away from PCs towards using mobile phones was causing a headache for crime fighters who were struggling to keep up with the fast pace of new handsets and platforms churned out by the mobile industry.”

Privacy Policies Are Great — For PhDs

septembre 4, 2008 · Filed Under Slashdot · Comment 

An anonymous reader writes “Major Internet companies say that they inform their customers about privacy issues through specially written policies. What they don’t say is that more often than not consumers would need college undergraduate educations or higher to easily wade through the verbiage. BNET looked at 20-some-odd privacy policies from Internet companies that received letters from the House about privacy practices. The easiest to read policy came from Yahoo, at a roughly 12th grade level. Most difficult? Insight Communications, which at a level of over 20 years of eduction officially puts it onto IRS Code territory.”

State Cannot Force Removal of SSNs From Privacy Advocate’s Site

août 28, 2008 · Filed Under Slashdot · Comment 

jvatcw brings us a story about Betty Ostergren, who operates a website dedicated to pointing out the social security numbers visible in public records. The purpose of the site is to raise awareness of privacy concerns regarding the personal information shared in Virginia’s governmental websites. Legislation was introduced in Virginia to combat Ostergren’s website, but last Friday a judge shot down the attempt to censor her, writing, “It is difficult to imagine a more archetypal instance of the press informing the public of government operations through government records than Ostergren’s posting of public records to demonstrate the lack of care being taken by government to protect the private information of individuals.”

Case Against Video-sharing Site Dismissed

août 28, 2008 · Filed Under Slashdot · Comment 

NewYorkCountryLawyer writes “A California copyright infringement case brought by an adult video maker against a video sharing web site, Veoh Networks, has been thrown out, based upon the ’safe harbor’ provision of the Digital Millennium Copyright Act (’DMCA’). In a 33-page decision (PDF), the Court concluded that Veoh was covered by the DMCA, and had carried out its duties to comply with takedown notices in a reasonable manner. The Court rejected the plaintiff’s arguments showing possible ways that users could do an end-around, saying that the law requires ‘reasonable’ compliance, rather than perfection, and noted that the DMCA is ‘designed to facilitate the robust development and world-wide expansion of electronic commerce, communications, research, development, and education in the digital age’.”

Black Screens For Unauthorized Copies of Windows

août 28, 2008 · Filed Under Slashdot · Comment 

arcticstoat writes “In a bid to deter people from using pirate versions of Windows XP, Microsoft is now updating its Windows Genuine Advantage (WGA) tool to introduce a few uncomfortable niggles for users of pirated versions of Windows. These include replacing the desktop wallpaper with a black screen every 60 minutes, although you can still replace it with your wallpaper of choice in the intervening period. As well as this, copies of Windows deemed to not be genuine will also have a translucent watermark above the system tray, which Microsoft calls a ‘persistent desktop notification.’”

Rover Exiting Crater To Continue Martian Marathon

août 28, 2008 · Filed Under Slashdot · Comment 

Riding with Robots writes “The robotic geologist Opportunity has nearly reached the rim of Victoria Crater, which it is leaving after a year of exploration inside. Rover handlers decided to abandon attempts to approach the crater’s cliff walls when they saw a power spike similar to the one that preceded a broken wheel on its twin, Spirit. Opportunity is already making do with a stuck robotic arm. The mission’s manager said, ‘Both rovers show signs of aging, but they are both still capable of exciting exploration and scientific discovery.’ Opportunity is set to continue trekking across the Meridiani Plains of Mars, even though its wheels have already seen 10 times the use they were designed for. Meanwhile, Spirit has survived yet another harsh Martian winter to produce another striking panorama.” Adam Korbitz notes other Mars-related news that funding has been approved for the Search for Extra-Terrestrial Genomes (SETG) Project. The project was one of 15 selected to receive funds through a NASA research opportunity program. The stated goal of the proposal is to “develop a PCR detector for in situ analysis on other planets, most immediately, Mars. This instrument is so sensitive it should allow the detection very low levels of microbial life on Mars, and will determine its phylogenetic position by analysis of the DNA sequence of the genes detected in situ.”

New Racing Simulation Distances Itself From Gamers

août 28, 2008 · Filed Under Slashdot · Comment 

waderoush writes “In an unusual move that could alienate a large segment of potential customers, iRacing.com, an online racing simulation company that opened its site to the public on August 26, is calling its system a ‘driver development tool’ that isn’t designed for PC or console gamers. ‘We don’t think of ourselves as a game company,’ says one exec. ‘World of Warcraft has a real appeal…But our system is more serious, frankly. If you are serious about racing, our product is for you, because getting on a [simulated] track with a full field of other drivers and racing against them safely involves as much commitment and time investment as if you went to racing school.’ In fact, to distinguish its system from MMOs, the company has come up with a new acronym to describe its simulation: MMIS, for ‘massively multiparticipant Internet sport.’”
