An anonymous reader writes "James Cameron is an engineer working on the OLPC project, specifically testing the wireless network capabilities of the OLPC XO laptop. Cameron lives in a small town called Tooraweenah in a remote region of the Australian outback. There is little noise in the spectrum in the area, so it's perfect for testing the wireless networking capabilities of the XO as it mirrors the kind of rural, spacious environment the XO is intended to be deployed in. Cameron breaks down exactly how the OLPC XO's mesh networking works, including the cheap US$35 solar powered mesh nodes that can be mounted on top of a tree to further the network's reach. Testing in the Australian outback, Cameron discovered that the range of the XO could go up to 1.6km 'quite easily' at 1.5m above ground. 'Assuming a range of 1.6km holds true, (the mathematical formula for area of a circle) Pi R squared tells us one well placed mesh node will cover up to eight square kilometers.' The article also includes numerous pictures of the mesh nodes and testing of the XO."

sspringer writes to let us know about Sun's continuing push to support scripting languages other than Java on its Java virtual machine. Sun just hired two key Python developers: Ted Leung, a long-time Python developer at the Open Source Applications Foundation, and Frank Wierzbicki, who is lead implementer of the Jython project. They will both work on Jython, which enables Python to run on the JVM. Last month Sun's CEO said the company wants to "take the J off the JVM and just make it a VM."

Rancid Altoid was one of a large number of readers to tell us that "Former U.S. President Gerald Ford, who was swept into office after the Watergate scandal and later pardoned Richard Nixon, died at age 93, his widow said on Tuesday."

Exter-C asks: "2006 was the year that a large amount of people started to talk Ubuntu as a possible contender for the Enterprise Linux desktop. There are several key issues that have to be raised: Is Ubuntu/Canonical really capable of maintaining Dapper Drake (6.06 LTS) for 5 years? I know this is not a new question but the evidence after 6 months seems to be negative. A case in point is the 4-5+ day delay for critical updates to packages like Firefox. Given that such a large percentage of people use their desktop systems on the web critical, browser vulnerabilities seem to be one of the core pieces of a secure desktop environment (user stupidity excluded). Can Ubuntu/Canonical really compete with the likes of Red Hat, who had patches available (RHSA-2006:0758) the day that the updates came out?"

SlinkySausage writes "Trojan horses masquerading as 'cracks for Vista' are starting to appear on pirate boards. More worrying though, Microsoft has confirmed that Vista's image-based install process is designed to allow third-party software to be slipstreamed into the installation DVD. Great for corporate deployment of Vista with software pre-installed, but also a huge benefit for malware writers, who can distribute Vista images with deeply-rooted malware."

theodp writes "Meet the point-and-click police. Newsweek reports that a growing number of ordinary officers are working a new beat, turning to MySpace to collect clues and crack offline cases. Most of the nabbed wrongdoers have been victims of their own hubris, like the two boys who uploaded video of themselves firebombing an abandoned airplane hangar earlier this month."

theodp writes "The NY Times reports on Geoff Goodfellow, possibly the real inventor of wireless e-mail, who says NTP was concerned that his earlier work might undermine its patent claims and went to some lengths to ensure that it did not, including gagging Goodfellow during the RIM lawsuit. Not only did high-school dropout Goodfellow - who hung out as a teen in the lab of Doug Englebart - describe wireless e-Mail in 1982, he implemented it in the early 1990's."

Pluvius writes "A recent post on GameSpot's Rumor Control blog suggests that there may be a chance for a new entry in the classic Star Control series in the foreseeable future. It would be developed by Toys for Bob, the creator of the first two games in the series, and it is implied that the company already holds the rights for the franchise. Quoting from the article: 'But maybe, just maybe, if enough of you people out there send [Alex Ness, producer] e-mails requesting that Toys For Bob do a legitimate sequel to Star Control 2, I'll be able to show them to [Toys For Bob parent company] Activision, along with a loaded handgun, and they will finally be convinced to roll the dice on this thing.'"

An anonymous reader writes to mention a piece on the Harvard Business School site talking about Lessons from the Browser Wars; specifically, what can be learned about first-mover advantages and the upsurge in Firefox use? From the article: "As a tool for exploring how standards are set when new technologies hit the market, the browser wars exhibit many features we like to study: competition between two viable alternatives, rapidly improving technologies, the ability of firms to use strategic levers such as market power and channels of distribution, growth in demand leading to diffusion of the new technology through the population, and uncertainty. Thus, this is one example from which we can generalize lessons regarding the outcome of diffusion of innovation into a market."

Dave Knott writes "The journal Nature will be publishing a report on an African catfish that hunts its prey on land. The fish wriggles out of the swamps to catch land-based prey. From the article: 'The eel catfish, Channallabes apus, catches unsuspecting victims by arching upwards and descending upon prey, trapping an insect against the ground before sucking it up. The same trick may have been used by the very first vertebrates to venture onto land, the researchers speculate.' There is a video of the fish in action."

theodp writes to mention a C|Net article about Chinese President Hu Jintao's historic first visit to the U.S.. The catch is that his first dinner won't be at the White House. It will be at Bill Gates' manse. From the article: "The approximately 100-person guest list is a who's who of the U.S. Pacific Northwest power elite, including Starbucks Chairman Howard Schultz and Washington state Gov. Christine Gregoire, said event organizers. The guests will undergo strict security checks before entering Gates' lodge-style, 66,000-square-foot home overlooking Lake Washington with a reported seven bedrooms, six kitchens, 24 bathrooms, a domed library, a reception hall and an artificial estuary stocked with salmon and trout. Gates and Gregoire are expected to introduce and welcome Hu, who will then offer a toast in front of the gathering."

DahBaker writes to mention a News.com story about an ingenious way to de-ice a surface. From the article: "Dartmouth College engineering professor Victor Petrenko, not to be confused with one of the Champions on Ice, has devised a way to use a burst of electricity to remove ice caked on walls or windows. For surfaces coated with a special film, the jolt gets rid of ice in less than a second, far less time than it takes to hack at it with an ice scraper. While drivers might find easy-cleaning windshields convenient, the technology--called thin-film pulse electrothermal de-icing, or PETD--could have significant economic impact if widely deployed. It could, for example, cut the costs of repairing power lines downed by ice storms and keep plane windshields frost-free, decreasing fuel consumption."

vegthura asks: "I have several coworkers that insist that logging into servers is an acceptable practice. They claim it's just easier than using sudo and it's just as safe - you know you're root so what else do you need? And why bother logging in as you if you're just going to use sudo to run commands with root privileges anyway? Everything I've ever read has been the exact opposite philosophy. There is very little you need to be root to do, if anything in practice, and using sudo lets you only use the power of root for when you really need it. So, die hard unix geeks, you've got root... do you use it or stick to sudo?"

An anonymous reader writes "A European version of the DARPA Grand Challenge is being held in Germany next month. Instead of a race through the desert, the EU challenge is split into three events. Urban, non-urban, and landmine detection will be the 'courses', with multiple winners in each event. Interestingly Sebastian Thrun, winner of last year's Challenge, has been forbidden from taking part despite being a European citizen." From the article: "The trials will take place in and around Hammelburg, a mockup of a town used by the German military for training exercises. In the non-urban course the robots will have to contend with a one-kilometer route containing ditches, barbed wire fences, cattle guards, fires, narrow underpasses, and inclines of up to 40 degrees. The urban and landmine 500-meter trials will require the robots to negotiate doorways, stairs, partially collapsed buildings, and poor visibility from smoke or partial lighting. Along the way, they will also have to search for designated objects and report their findings back to base."
