Space Is Just a Little Bit Closer Than Expected 130

Posted by timothy from the winter-shrinkage dept.
SpuriousLogic points out a BBC story which begins "The upper reaches of Earth's atmosphere are much lower than expected, a US Air Force satellite has found. Currently, the ionosphere — a layer of charged particles that envelopes the planet — is at an altitude of about 420km, some 200km lower than expected. The behaviour of the ionosphere is important because disturbances in its structure can upset satellite communications and radar."

With Lawsuit Settled, Hackers Working With MBTA 90

Posted by ScuttleMonkey from the how-it-should-be dept.
narramissic writes "The three MIT students who were sued earlier this year by the Massachusetts Bay Transit Authority for planning to show at Defcon how they had had reverse engineered the magnetic stripe tickets and smartcards said Monday that they are now working to make the Boston transit system more secure. 'I'm really glad to have it behind me. I think this is really what should have happened from the start,' said Zack Anderson, one of the students sued by the MBTA."

Why Use Virtual Memory In Modern Systems? 983

Posted by timothy from the virtually-useless dept.
Cyberhwk writes "I have a system with Windows Vista Ultimate (64-bit) installed on it, and it has 4GB of RAM. However when I've been watching system performance, my system seems to divide the work between the physical RAM and the virtual memory, so I have 2GB of data in the virtual memory and another 2GB in the physical memory. Is there a reason why my system should even be using the virtual memory anymore? I would think the computer would run better if it based everything off of RAM instead of virtual memory. Any thoughts on this matter or could you explain why the system is acting this way?"

Talk-Powered Cell Phones Won't Need Batteries 197

Posted by samzenpus from the talk-charging dept.
alphadogg writes "It's possible that in the future conversations on your cell phone could generate enough electrical power to run the phone, without batteries. That's one possible outcome of recent work by a team of Texas researchers, who appear to have discovered that by building a certain type of piezoelectric material to a specific thickness (about 21 nanometers, compared to a typical human hair of 100,000 nanometers), you can boost its energy production by 100 percent. And the technology could power not just phones, but a whole range of low-power mobile devices and sensors. The breakthrough is an example of 'energy harvesting' that can convert one kind of energy, such as vibrations or solar rays, into electricity."

Replacing Metal Detectors With Brain Scans 327

Posted by kdawson from the what-is-it-you-intend dept.
Zordak writes "CNN has up a story about several Israeli firms that want to replace metal detectors at airports with biometric readings. For example, with funding from TSA and DHS, 'WeCU ([creepily] pronounced "We See You") Technologies, employs a combination of infra-red technology, remote sensors and imagers, and flashing of subliminal images, such as a photo of Osama bin Laden. Developers say the combination of these technologies can detect a person's reaction to certain stimuli by reading body temperature, heart rate and respiration — signals a terrorist unwittingly emits before he plans to commit an attack.' Sensors may be embedded in the carpet, seats, and check-in screens. The stated goal is to read a passenger's 'intention' in a manner that is 'more fair, more effective and less expensive' than traditional profiling. But not to worry! WeCU's CEO says, 'We don't want you to feel that you are being interrogated.' And you may get through security in 20 to 30 seconds."

Lessig, Zittrain, Barlow To Square Off Against RIAA 288

Posted by timothy from the ensemble-cast dept.
NewYorkCountryLawyer writes "The RIAA's case in Boston against a 24-year-old grad student, SONY BMG Music v. Tenenbaum, in which Prof. Charles Nesson of Harvard Law School, along with members of his CyberLaw class, are representing the defendant, may shape up as a showdown between the Electronic Frontier and Big Music. The defendant's witness list includes names such as those of Prof. Lawrence Lessig (Author of 'Free Culture'), John Perry Barlow (former songwriter of The Grateful Dead and cofounder of the Electronic Frontier Foundation), Prof. Johan Pouwelse (Scientific Director of P2P-Next), Prof. Jonathan Zittrain (Author of 'The Future of the Internet — And How to Stop It'), Professors Wendy Seltzer, Terry Fisher, and John Palfrey, and others. The RIAA requested, and was granted, an adjournment of the trial, from its previously scheduled December 1st date, to March 30, 2009. (The RIAA lawyers have been asking for adjournments a lot lately, asking for an adjournment in UMG v. Lindor the other day because they were so busy preparing for the Tenenbaum December 1st trial ... I guess when you're running on hot air, you sometimes run out of steam)."

Ender in Exile Screenshot-sm 507

Posted by samzenpus from the read-all-about-it dept.
stoolpigeon writes "Orson Scott Card's work Ender's Game began as a novelette, which he says he wrote as a means of leading up to the full story he had developed, Speaker for the Dead. Ender's Game was published as a full novel in 1985, and won the Hugo and Nebula awards (as did Speaker for the Dead in '86 and '87). I think it is safe to say that Ender's Game is ensconced in its position as a science fiction classic. Now, 23 years later, Card has finished the first direct sequel to Ender's Game in his new novel Ender in Exile." Keep reading for the rest of JR's review.

I'm also trying to figure out how a solar wind shield (a few keV) would do anything for cosmic ray particles (GeV, anyone?)

I trust the folks at RAL to be doing good work. I think the real news here is in the size of the protected area: magnetic fields deflecting charged particles is hardly new. Their trial is billed as a metre across, whereas the solar wind DeBye length is on the order of 10m. So they're dealing with scales smaller than a typical plasma treatment. I'll have to read the actual article to be sure.

MI6 Terror Photos, Data Accidentally Sold On Ebay 317

Posted by timothy from the that's-ar15-for-ordinary-citizens dept.
Barence writes "In what's turning out to be a bad week for security in the UK, confidential MI6 documents, fingerprints and photos relating to suspected Al-Qaeda terrorists have been found in the memory of the second-hand Nikon Coolpix camera, which was bought on eBay for only £17. The buyer immediately went to the police, who initially treated it as a joke; when they realised he was serious, they swooped on his home and seized his camera and PC. Remember, this is the same MI6 which plans to recruit new members via Facebook, a userbase not exactly famous for its dedication to privacy, security and discretion. The news comes on the back of yesterday's embarrassment over a local council whose VPN device ended up on eBay with confidential login details left on it."

State of Kentucky Seizes Control of 141 Domain Names 505

Posted by timothy from the when-the-state-is-an-avaricious-prig dept.
ashmodai9 writes "In a rather interesting (read: insane) decision, a district judge in the State of Kentucky has awarded control of 141 online gambling domain names to the governor of the state. Most of these are hosted offshore, and very few are registered under US domain name registrars, let alone registrars in the State of Kentucky (are there any?). You can check out the press release here, and confirm that the Commonwealth of Kentucky does in fact now 'own' these domain names by performing a WHOIS search on any of the domains listed here."

Nuclear Decay May Vary With Earth-Sun Distance 418

Posted by kdawson from the not-so-fast-there dept.
KentuckyFC writes "We've long thought that nuclear decay rates are constant regardless of ambient conditions (except in a few special cases where beta decay can be influenced by powerful electric fields). So that makes it hard to explain two puzzling experiments from the 1980s that found periodic variations over many years in the decay rates of silicon-32 and radium-226. Now a new analysis of the raw data says that changes in the decay rate are synchronized with each other and with Earth's distance from the sun. The physicists behind this work offer two theories to explain why this might be happening (abstract). First, some theorists think the sun produces a field that changes the value of the fine structure constant on Earth as its distance from the sun varies. That would certainly affect the rate of nuclear decay. Another idea is that the effect is caused by some kind of interaction with the neutrino flux from the sun's interior which also varies with distance. Take your pick. What makes the whole story even more intriguing is that for years physicists have disagreed over the decay rates of several isotopes such as titanium-44, silicon-32, and cesium-137. Perhaps they took their data at different times of the year?"

Full Immersion Cooling Comes To Desktop PCs 192

Posted by timothy from the please-don't-drink-the-flourinert dept.
mr_sifter writes "After three years of research and around £100,000 of R&D costs, UK-based Armari has unveiled its XCP prototype. It's a full immersion liquid cooled PC which supports standard ATX components. Unlike conventional liquid cooled PCs, the components are all easy to swap in and out as they're swimming in liquid, rather than under waterblocks. It also looks amazing, pumping around 70KG of electrically inert cooling fluid (salvaged from an old Cray) around its military grade perspex shell."

The Duke Is Finally Back, For Real 309

Posted by kdawson from the better-be-good dept.
After the first announcement on 1997-04-27 and over eleven years of fresh start after fresh start, Duke Nukem Forever finally comes to your system. At least if your system is an Xbox 360. Jon Siegler, the webmaster of 3D Realms, confirms this on their site: "As has been reported around the net today, we can confirm that the game has indeed passed final certification with Microsoft on Friday the 15th of August (on our first try, no less). That means the game is done — it is now in the hands of Microsoft." Update: 08/19 10:47 GMT by T : Several readers have written with a correction: this announcement is actually about Duke Nukem 3D, rather than Duke Nukem Forever.

Tracking Near-Earth Meteors With a 1.1 Petabyte Database 72

Posted by Soulskill from the outer-space-and-computing-make-for-big-numbers dept.
Lucas123 writes "The latest and most ambitious attempt to detect 'near-Earth objects' (NEOs) is the Panoramic Survey Telescope and Rapid Response System, or Pan-STARRS. When it's fully operational several years from now, it will have four telescopes, each with a 1.4-gigapixel camera. The system is expected to be able to track virtually all NEOs larger than 300 meters in diameter as well as many smaller ones. Rather than turning to an expensive supercomputer equipped with hundreds or thousands of processors, Pan-STARRS will use a cluster of 50 PC servers connected to 1.1 petabytes of disk storage via fast Infiniband networking gear."
