Distributed.net Finds Optimal 25-Mark Golomb Ruler 265

kpearson writes "Distributed.net's 8-year-old OGR-25 distributed computing project has just proven conclusively that the predicted shortest 25-mark Golomb ruler is optimal. 'The total length of the ruler is 480, with marks at positions: 0 12 29 39 72 91 146 157 160 161 166 191 207 214 258 290 316 354 372 394 396 431 459 467 480. (This ruler may alternatively be expressed in terms of the distance between those positions, which is how dnetc displays them: 12-17-10-33-19-...).' 124,387 people participated in the project and two people found the shortest ruler, one on October 10, 2007 and the other on March 24, 2008."

Half of American Doctors Often Prescribe Placebos 238

damn_registrars writes "'Half of all American doctors responding to a nationwide survey say they regularly prescribe placebos to patients. The results trouble medical ethicists, who say more research is needed to determine whether doctors must deceive patients in order for placebos to work.' The study just quoted goes on to say that the drugs most often used as placebo are headache pills, vitamins, and antibiotics. Studies on doctors in Europe and New Zealand have found similar results."

What Normal Users Can Expect From Ubuntu 8.10 511

notthatwillsmith writes "With Ubuntu 8.10 due to be released in just a few days, Maximum PC pored through all the enhancements, updates, and new features that are bundled into the release of Intrepid Ibex and separated out the new features that are most exciting for Linux desktop users. Things to be excited about? With new versions of GNOME and X.Org, there's quite a bit, ranging from the context-sensitive Deskbar search to an audio and video compatible SIP client to the new Network Manager (manage wired, Wi-Fi, VPN, and cellular broadband connections in one place)."

Security Flaw In Android Web Browser 59

r writes "The New York Times reports on a security flaw discovered in the new Android phones. The article is light on details, but it hints at a security hole in the browser, allowing for trojans to install themselves in the same security partition as the browser: 'The risk in the Google design, according to Mr. Miller, who is a principal security analyst at Independent Security Evaluators in Baltimore, lies in the danger from within the Web browser partition in the phone. It would be possible, for example, for an intruder to install software that would capture keystrokes entered by the user when surfing to other Web sites. That would make it possible to steal identity information or passwords.'"

Packs of Robots Will Hunt Down Uncooperative Humans 395

Ostracus writes "The latest request from the Pentagon jars the senses. At least, it did mine. They are looking for contractors to 'develop a software/hardware suite that would enable a multi-robot team, together with a human operator, to search for and detect a non-cooperative human subject. The main research task will involve determining the movements of the robot team through the environment to maximize the opportunity to find the subject ... Typical robots for this type of activity are expected to weigh less than 100 Kg and the team would have three to five robots.'" To be fair, they plan to use the Multi-Robot Pursuit System for less nefarious-sounding purposes as well. They note that the robots would "have potential commercialization within search and rescue, fire fighting, reconnaissance, and automated biological, chemical and radiation sensing with mobile platforms."

In UK, Broadband Limits Confuse Nine In Ten Users 217

Mark Jackson writes "ISPreview reports that 86% of UK broadband users don't understand the usage limits on their service, and nearly one million have reached or exceeded their ISPs limit in the last year. This is important because 56% of major providers are prepared to disconnect those who 'abuse' the service. However, it also shows how damaging bad marketing can be, with 6.2M people believing they have an 'unlimited' service with no restrictions. The UK Advertising Standards Authority is also blamed for making the problem worse by allowing providers to describe their services as unlimited even if there is a usage cap, as long as it is detailed in the small print. However, consumers are none the wiser with over 10 million broadband customers never reading their usage agreements and a further 1.8M not knowing whether they have read it or not. Unsurprisingly 7.5M do not even know their download limit, which is understandable when so few providers clarify it."

Amazon Beefs Up Its Cloud Ahead of MS Announcement 89

Amazon has announced several major improvements to its EC2 service for cloud computing. The service is now in production (no longer beta); it offers a service-level agreement; and Windows and SQL Server are available in beta form. ZDNet points out that all this news is intended to take some wind out of Microsoft's sails as MS is expected to introduce its own cloud services next week at its Professional Developers Conference.

1000-mph Car Planned 380

Smivs notes a BBC report on a British team planning a 1000-mph record-breaking car. The previous land-speed record broke the sound barrier. The proposed vehicle will get from 0 to 1,050 mph in 40 seconds. "RAF pilot Andy Green made history in 1997 when he drove the Thrust SSC jet-powered vehicle at 763 mph (1,228 km/h). Now he intends to get behind the wheel of a car that is capable of reaching 1,000 mph (1,610 km/h). Known as Bloodhound, the new car will be powered by a rocket bolted to a Typhoon-Eurofighter jet engine. The team-members have been working on the concept for the past 18 months and expect to be ready to make their new record attempt in 2011."

Open Source Hardware, For Fun and For Profit 122

ptorrone writes "Lots of open source hardware articles making the rounds this week, first up — Wired has an excellent piece on the Arduino project, an open source electronics prototyping platform, its founders and business model (they have sold over 50,000 units). And next up MIT's Tech Review has a profile on a few open source hardware businesses including NYC based Adafruit Industries best known for projects like the open source synth (x0x0b0x) and 'fun' projects like the Wave Bubble, the open source cell phone/wifi/GPS/RF jammer."

Researchers Find Problems With RFID Passport Cards 172

An anonymous reader writes "Researchers at the University of Washington have found that RFID tags used in two new types of border-crossing documents in the US are vulnerable to snooping and copying. The information in these tags could be copied on to another, off-the-shelf tag, which might be used to impersonate the legitimate holder of the card." You can also read the summary of the researchers' report.

Australia Developing Massive Electric Vehicle Grid 260

blairerickson writes "A US firm Thursday unveiled plans to build a massive one-billion-dollar charging network to power electric cars in Australia as it seeks cleaner and cheaper options to petrol. Better Place, which has built plug-in stations for electric vehicles in Israel and Denmark, has joined forces with Australian power company AGL and finance group Macquarie Capital to create an Australian network. Under the plan, the three cities will each have a network of between 200,000 and 250,000 charge stations by 2012 where drivers can plug in and power up their electric cars. The points would probably be at homes and businesses, car parks and shopping centres. In addition, 150 switch stations will be built in each city and on major freeways, where electric batteries can be automatically replaced in drive-in stations similar to a car wash." I hope they're talking to the car companies about the necessary standardization it would take to make this work, too.

Bioshock 2 Trailer Released, Platform Information Revealed 85

arcticstoat writes "If you've played Bioshock, you'll know it can be a tough choice deciding whether you're going to kill the cute (yet evil looking) Little Sisters and extract their ADAM, or let them live. Your choice even affects whether you're given one of three possible endings of the game, and their story will now continue to be told in the sequel. 2K Games has just released a trailer for the new game, showing what appears to be a grown up Little Sister, still clutching a toy, while the city structure of Rapture springs up around her. No gameplay is shown, but it does give a hint as to what the game will be about, and it looks as though the game may take you onto dry land." Gamespot initially confirmed the trailer's authenticity after it was leaked last week. A representative from 2K Games also mentioned Bioshock 2 was "destined for the PlayStation 3, Xbox 360 and Windows PC platforms."
Censorship

Australian Government Censorship 'Worse Than Iran' 516

An anonymous reader writes "The Australian Government's plan to Censor the Internet is producing problems for ISPs, with filters causing speeds to drop by up to 86% and falsely blocking 10% of safe sites. The Government Minister in charge of the censorship plan, Conservative Stephen Conroy, has been accused of bullying ISP employees critical of his plan: 'If people equate freedom of speech with watching child pornography, then the Rudd Labor Government is going to disagree.'" Read on for more, including an interesting approach to demonstrating the inevitable collision of automated censorship with common sense.

Open-Source DRM Ready To Take On Big Guns 520

Barence writes "An open-source digital rights management (DRM) scheme says it's ready to supplant Apple and Microsoft as the world's leading copy protection solution. Marlin, which is backed by companies such as Sony and Samsung, has just announced a new partner program that aims to drive the DRM system into more consumer devices. 'It works in a way that doesn't hold consumers hostage,' Talal Shamoon told PC Pro. 'It allows you to protect and share content in the home, in a way that people own the content, not the devices.' When asked about the biggest problem of DRM — that customers hate it — he argued that 'the biggest problem with DRM is people have implemented it badly. Make DRM invisible and people will use it.'"

Microsoft Working For Samba Interoperability 221

JP writes "Andrew Bartlett of Samba fame has written a document describing their recent collaboration with Microsoft's Active Directory team. In brief, it would seem that the sky is falling, as Microsoft's engineers seem to be really committed to making Samba fully interoperable with AD. They have organized interoperability fests and have knowledgeable engineers answering technical questions without legal or marketing drones getting in the way. However according to Andrew the Samba AD team is currently very short on manpower, so if you have network experience, now is the time to get coding."
