Journal Journal: Who owns your online profile

Writing for PC World, Katherine Noyes reports that companies are monitoring their employees online profiles at LinkedIn and Facebook. If I understood the report correctly, the monitoring software has the power to block user changes to their profiles. As a self-employed person I am not immediately affected, but am certainly not ethusiastic. I don't think that this will

Submission + - New Imaging Technique Explains Unconsciousness (manchester.ac.uk)

smitty777 writes: A new imaging technique called fEITER (for functional Electrical Impedance Tomography by Evoked Response) attempts to explain the process of slipping into unconsciousness. The fEITER is a portable device that creates 3D imagery based on evoked potentials measured hundreds of times a second.

The interesting finding from these studies is that unconsciousness appears to result from a buildup of inhibitor neurons. From the article: “Our findings suggest that unconsciousness may be the increase of inhibitory assemblies across the brain’s cortex. These findings lend support to Greenfield’s hypothesis of neural assemblies forming consciousness.”

Submission + - cheap swarm robot (ieee.org)

An anonymous reader writes: hey're fairly simple little robots about the size of a quarter that can move around on vibrating legs, blink their lights, and communicate with each other. On an individual basis, this isn't particularly impressive, but Kilobots aren't designed to be used on an individual basis. Costing a mere $14 each and buildable in about five minutes, you don't just get yourself one single Kilobot. Or ten. Or a hundred. They're designed to swarm in the thousands,

Submission + - Military Drone attacks are not "hostile" (huffingtonpost.com)

sanzibar writes: Not satisfied with the legal conclusion of the DOJ, the Obama administration finds other in-house lawyers willing to declare a bomb dropped from a drone is not "hostile".

The strange conclusion has big implications in determining the Presidents compliance with the law. If drone strikes are in fact hostile and he continues his Libyan campaign past Sunday, he may very well be breaking the law.

Submission + - First exploit on quantum cryptography confirmed (physicsworld.com)

Vadim Makarov writes: "The Physics World reports researchers demonstrating a full eavesdropper on a quantum key distribution link. Unlike conventional exploits for security vulnerabilities that are often just a piece of software, spying on quantum cryptography required a box full of optics and mixed-signal electronics. Details are published in Nature Communications, and as a free preprint. The vulnerability was known before, but this is the first actual working exploit with secret-key recording confirmed. Patching this loophole is in progress.

Disclaimer: I am one of the researchers who worked on this."

Dead Space Wants To Scare You 195

Kotaku recently ran a story questioning whether the survival-horror genre still exists, and how Dead Space may or may not fit into it. With reviews for the game starting to come in, Ars Technica reports that the game is, indeed, both scary and good. Gamespy wrote up a Dead Space survival guide, and Gamasutra has a lengthy interview with the game's senior producer. In the production of the game, the developers studied things like car wrecks and war scenes to increase the level of realism. They also want the game's sounds to terrify players, including appropriately timed silence. The launch trailer is also available, though it does contain spoilers.

CERN Releases Analysis of LHC Incident 149

sash writes "From the fresh press release: 'Investigations at CERN following a large helium leak into sector 3-4 of the Large Hadron Collider tunnel have confirmed that cause of the incident was a faulty electrical connection between two of the accelerator's magnets. This resulted in mechanical damage and release of helium from the magnet cold mass into the tunnel. Proper safety procedures were in force, the safety systems performed as expected, and no one was put at risk. Sufficient spare components are in hand to ensure that the LHC is able to restart in 2009, and measures to prevent a similar incident in the future are being put in place.'"

Defining Progression Within Games 55

GameSetWatch is running a piece discussing some of the ways in which gameplay can progress from simple to complex. The author talks about how acquiring items, new abilities, or just increasing the player's overall effectiveness can make it difficult for game designers to keep their content balanced and interesting. Quoting: "What do I mean by progression? There are at least two distinct types of progression in computer games, which I'll label player progression, and character progression (narrative progression is arguably a third). Player progression is the increasing aptitude of the player in mastering the game: whether through learning and understanding the technical rules of the game (surface play) or the implications of those rules (deep play). ... Character progression is the unlocking of additional rules of play, or altering the existing rules, by choices or actions within the game."

Paul Krugman Awarded Nobel Prize For Economics 425

zogger writes in his journal, "The guy who put together the concept of geographical location combined with cheap transportation leading to 'like trades with like' and the rise of superindustrial trading blocs has won the Nobel economics science prize. He's a bigtime critic of a lot of this administration's policies, and is unabashedly an FDR-economy styled fella. Here is his blog at the NYTimes." Reader yoyoq adds that Krugman's career choice was inspired by reading Asimov's Foundation series at a young age.

Submission + - How FairPlay Works: Apple's iTunes DRM Dilemma

An anonymous reader writes: Understanding how Apple's FairPlay DRM works helps to answer a lot of questions: why it hasn't been replaced with an open, interoperable DRM that anyone can use, why Apple isn't broadly licensing FairPlay, and why the company hasn't jumped to add DRM-free content from indie artists to iTunes.

Submission + - UW scientists unlock major number theory puzzle

Jake's Mom writes: "From the University of Wisconsin — UW scientists unlock major number theory puzzle.

"Mathematicians have finally laid to rest the legendary mystery surrounding an elusive group of numerical expressions known as the "mock theta functions."

Number theorists have struggled to understand the functions ever since the great Indian mathematician Srinivasa Ramanujan first alluded to them in a letter written on his deathbed, in 1920.

Now, using mathematical techniques that emerged well after Ramanujan's death, two number theorists at the University of Wisconsin-Madison have pieced together an explanatory framework that for the first time illustrates what mock theta functions are, and exactly how to derive them."

Bloggers Immune From Suits Against Commenters 142

An anonymous reader writes "Suppose a commenter posts a libelous comment here at Slashdot. Can Slashdot and its owners be sued for defamation? A federal appeals court just held that no, they cannot. The court noted that a federal law was designed to ensure that 'within broad limits, message board operators would not be held responsible for the postings made by others on that board,' adding that, were the law otherwise, it would have an 'obvious chilling effect' on blogger speech."

British Government Slashes Scientific Research 168

asobala writes "The British Government has slashed the funding of scientific Research Councils by £68 million. The Research Councils most affected by this include the Engineering and Physical Sciences Research Council, which has been hit by a £29 million reduction in funding, and the Medical Research Council, which is seeing a £10.7 million reduction in funding. The response of the BBSRC biological research council announces that the council will have to cut 20 new grants and reduce expenditure on new equipment."

Submission + - The ghost of the Newton haunts Apple's iPhone

PetManimal writes: "David Haskin has looked back at why the Newton failed to succeed in the early PDA market, and warns that Apple may be setting itself up for a similar failure with the iPhone. The iPhone appears to have a revolutionary interface, and the product has generated tons of interest from the Mac community — just like the Newton did, back in the 1990s. But the iPhone also shares with the Newton a hefty starting price — $500 for the iPhone, vs. $700 (in 1993 dollars) for the Newton. And Joe Public may not be so keen on the cost, as recent survey data suggests (see Slashdot discussion). Moreover, Haskin notes that the iPhone will have to deal with two additional factors that were not issues for the Newton: Competition, and wireless service providers: 'Besides overcharging for iPhone, Apple faces significant competition, something it didn't face in 1993 when it launched Newton. And you can bet that competition from the likes of Samsung and LG will both be good (although probably not as good as iPhone) and most assuredly cheaper. It's also becoming clear that Apple may be suffering from excessive hubris. That is evident by its strong demands on its partner in the U.S., Cingular/AT&T. The demands, including a slice of the cellular revenues and control of the sales channel, were so strong that Verizon Wireless turned the deal down. I'm more convinced than ever that, after an initial frenzy of publicity and sales to early adopters, iPhone sales will be unspectacular. If Apple doesn't respond quickly by lowering the price and making nice to AT&T, which surely will be ticked off, iPhone may well become Apple's next Newton. Remember that two years after Newton was introduced, a smaller, cheaper PDA appeared — the Palm Pilot — which truly did rock the world.'"
