Submission + - Contributors Leaving Wikipedia in Record Numbers

Hugh Pickens writes: "CNET reports that the volunteers who create Wikipedia's pages, check facts and adapt the site are abandoning Wikipedia in unprecedented numbers with tens of thousands of editors going “dead” — no longer actively contributing and updating the site — a trend many experts believe could threaten Wikipedia’s future. In the first three months of 2009 the English-language version of Wikipedia suffered a net loss of 49,000 contributors, compared with a loss of about 4,900 during the same period in 2008. “If you don’t have enough people to take care of the project it could vanish quickly," says Felipe Ortega at the Universidad Rey Juan Carlos in Madrid who created a computer system to analyze the editing history of more than three million active Wikipedia contributors in ten different languages. "We’re not in that situation yet. But eventually, if the negative trends follow, we could be in that situation.” Contributors are becoming disenchanted with the process of adding to the site which is becoming increasingly difficult says Andrew Dalby, author of The World and Wikipedia: How We are Editing Reality and a regular editor of the site. “There is an increase of bureaucracy and rules. Wikipedia grew because of the lack of rules. That has been forgotten. The rules are regarded as irritating and useless by many contributors.” Arguments over various articles have also taken their toll. "Many people are getting burnt out when they have to debate about the contents of certain articles again and again," adds Ortega."

Submission + - Amazing Software Turns Cheap Webcam Into Instant 3 (wired.com)

tugfoigel writes: It is called ProFORMA, or Probabilistic Feature-based On-line Rapid Model Acquisition, but it is way cooler than it sounds. The software, written by a team headed by Qi Pan, a student at the Department of Engineering at Cambridge University in England, turns a regular, cheap webcam into a 3D scanner.

Normally, scanning in 3D requires purpose-made gear and time. ProFORMA lets you rotate any object in front of the camera and it scans it in real time, building a fully 3D texture mapped model as fast as you can turn an object. Even more impressive is what happens after the scan: The camera continues to track the object in space and matches its movement instantly with the on-screen model.

Submission + - Diamonds Deliver Speed Boost To Quantum Computers (gizmag.com)

ElectricSteve writes: Scientists at UC Santa Barbara have made important advances in the field of spintronics by demonstrating the ability to electrically manipulate, at room temperatures, the quantum states of electrons trapped in the atomic structural defects of diamond crystals. Despite previous indications to the contrary, such quantum states can be manipulated very quickly, even at gigahertz frequencies, paving the way to significantly faster quantum computing.

Submission + - DroboPro 8-Bay In-depth: Hardware RAID at its Best 1

Vigile writes: Everyone seems to love Drobo storage products, especially the new additions to their line, but some remain hesitant to move to an external solution using a non-standard RAID level. PC Perspective's destroyer of SSD's took a crack at the DroboPro, doing his best to trip it up, and exploring all of its features in detail. As it turns out the DroboPro got the better of the tester and was able to survive all sorts of simulated destruction including yanking out the power cord during streaming writes to the unit. The unfortunate part is that the DroboPro is limited to iSCSI, Firewire, USB and eSATA connections for a steep $1495 retail price.

Major IE8 Flaw Makes "Safe" Sites Unsafe 83

After this weekend's report of a dangerous flaw in IE (which Microsoft confirmed today), intrudere points out an exclusive report in The Register on a new hole in IE8 that could allow an attacker to pull off cross-site scripting attacks on Web sites that ought, by rights, to be safe from XSS. This is according to two anonymous sources, who told El Reg that Microsoft had been notified of the vulnerability a few months ago.

New Theory of Gravity Decouples Space & Time 575

eldavojohn writes "Petr Horava, a physicist at the University of California in Berkeley, has a new theory about gravity and spacetime. At high energies, it actually snips any ties between space and time, yet at low energies devolves to equivalence with the theory of General Relativity, which binds them together. The theory is gaining popularity with physicists because it fits some observations better than Einstein's or Newton's solutions. It better predicts the movement of the planets (in an idealized case) and has a potential to create the illusion of dark matter. Another physicist calculated that under Horava Gravity, our universe would experience not a Big Bang but a Big Bounce — and the new theory reproduces the ripples from such an event in a way that matches measurements of the cosmic microwave background."

WHO Raises Swine Flu Threat Level 557

Solarch writes "Late in the afternoon on Wednesday, the WHO raised the pandemic threat level for H1N1 "swine flu" to 5. Global media outlets(such as CNN, Fox News, and the BBC) preempted normal broadcast coverage and immediately published stories on their websites. To clarify, the WHO's elevation is mainly a sign to governments that the virus is spreading quickly and that steps should be taken on a governmental level to stage supplies and medicines to combat a possible pandemic. Unfortunately, broadcast coverage focused on phrases like 'pandemic imminent' (CNN marquee). In other news, patient zero, the medical term for the initial human vector of a disease, has been tentatively identified in Mexico."

Biotech Company To Patent Pigs 285

Anonymous Swine writes "Monsanto, a US based multinational biotech company, is causing a stir by its plan to patent pig-breeding techniques including the claim on animals born by the techniques. 'Agricultural experts are scrambling to assess how these patents might affect the market, while consumer activists warn that if the company is granted pig-related patents, on top of its tight rein on key feed and food crops, its control over agriculture could be unprecedented. "We're afraid that Monsanto and other big companies are getting control of the world's genetic resources," said Christoph Then, a patent expert with Greenpeace in Germany. The patent applications, filed with the World Intellectual Property Organization, are broad in scope, and are expected to take several years and numerous rewrites before approval.'"

Computer Spies Breach $300B Fighter-Jet Project 330

suraj.sun writes "Computer spies have broken into the Pentagon's $300 billion Joint Strike Fighter project — the Defense Department's costliest weapons program ever — according to current and former government officials familiar with the attacks. Similar incidents have also breached the Air Force's air-traffic-control system in recent months, these people say. In the case of the fighter-jet program, the intruders were able to copy and siphon off several terabytes of data related to design and electronics systems, officials say, potentially making it easier to defend against the craft."

Physicists Propose New Kind of Quantum Tunneling 163

KentuckyFC writes to tell us that scientists from the UK and Germany are proposing a third kind of quantum tunneling. They propose that a quantum particle is capable of changing into a pair of "virtual particles" capable of passing through a potential barrier before changing back. The supposition also provides some interesting methods of possibly testing string theory. So many interesting and useful possibilities, I guess that just means it will be debunked faster than other scientific theories.

Vatican To Build 100 Megawatt Solar Power Plant 447

Karim Y. writes "The Vatican is going solar in a big way. The tiny state recently announced that it intends to spend 660 million dollars to create what will effectively be Europe's largest solar power plant. This massive 100 megawatt photovoltaic installation will provide enough energy to make the Vatican the first solar powered nation state in the world! 'The 100 megawatts unleashed by the station will supply about 40,000 households. That will far outstrip demand by Pope Benedict XVI and the 900 inhabitants of the 0.2 square-mile country nestled across Rome's Tiber River. The plant will cover nine times the needs of Vatican Radio, whose transmission tower is strong enough to reach 35 countries including Asia.'"

Where's Your Coding Happy Place? 508

jammag writes "Cranking out code — your very best code — requires being in the optimal environment, muses developer Eric Spiegel. He explores the pitfalls and joys of the usual locales, cubicle, home, the beach. He claims he's done his best coding on an airplane. In the end, though, he suggests that the best environment is a matter of the environment inside yourself, your internal mood — and to hell with the cubicle or wherever. You have to be focused on quality, regardless of the idiot clients. It's all inside your mind. Where's your coding happy place?"
