diegocgteleline.es writes "Valerie Aurora, a Linux file system developer and ex-ZFS designer, has posted an article with great insight on how Btrfs, the file system that will replace Ext4, was created and how it works. Quoting: 'When it comes to file systems, it's hard to tell truth from rumor from vile slander: the code is so complex, the personalities are so exaggerated, and the users are so angry when they lose their data. You can't even settle things with a battle of the benchmarks: file system workloads vary so wildly that you can make a plausible argument for why any benchmark is either totally irrelevant or crucially important. ... we'll take a behind-the-scenes look at the design and development of Btrfs on many levels — technical, political, personal — and trace it from its origins at a workshop to its current position as Linus's root file system.'"

katarn writes "General Fusion is a startup proposing they can create commercially viable fusion using acoustic shock waves, triggered by 220 precisely controlled pneumatic pistons. Their approach is based on a US Naval research concept called 'Linus' and old research done by General Atomics. They feel we now have the high-speed, digital processing capable of pulling off this feat, where decades ago the technology was not available. I think we can hold off on the 'vaporware' claims for a bit; everyone is aware of the horrible track record for turning fusion concepts into reality, but they don't claim to be the first with the idea or that there are not substantial challenges in the way. If nothing else, it is a fascinating concept." Los Alamos National Laboratory has further details on this type of fusion, and longtime LANL researcher Ronald Kirkpatrick did an external assessment (PDF) of General Fusion's plans. Popular Science had a lengthy story about the company a while back. The reason they're back in the headlines now is that they've secured enough funding to begin work on a prototype reactor.

Dr_Ken writes to mention recent coverage of a Harvard Cyber-Law study on Techdirt that analyzes the uses of copyright in the academic world. Some are claiming that the applications of copyright in academia are stifling and that we should perhaps go so far as to abolish copyright in the academic world entirely. "I've even heard of academics who had to redo pretty much the identical experiment because they couldn't even cite their own earlier results for fear of a copyright claim. It leads to wacky situations where academics either ignore the fact that the journals they published in hold the copyright on their work, or they're forced to jump through hoops to retain certain rights. That's bad for everyone."

snydeq writes "Fatal Exception's Neil McAllister questions whether Scheme, a dialect of Lisp taught as part of many first-year CS curricula and considered by some to be the 'latin of programming,' is really the best first language for a young programmer. As he sees it, the essentially write-only Scheme requires you to bore down into the source code just to figure out what a Scheme program is trying to do — excellent for teaching programming but 'lousy for a 15-year-old trying to figure out how to make a computer do stuff on his own.' And though the 'hacker ethic' may in fact be harming today's developers, McAllister still suggests we encourage the young to 'develop the innate curiosity and love of programming that lies at the heart of any really brilliant programmer' by simply encouraging them to fool around with whatever produces the most gratifying results. After all, as Jeff Atwood puts it, 'what we do is craftmanship, not engineering,' and inventing effective software solutions takes insight, inspiration, deduction, and often a sprinkling of luck. 'If that means coding in Visual Basic, so be it. Scheme can come later.'"

Hugh Pickens writes "A science-savvy robot called Adam has successfully developed and tested its first scientific hypothesis, discovering that certain genes in baker's yeast code for specific enzymes which encourage biochemical reactions in yeast, then ran an experiment with its lab hardware to test its predictions, and analyzed the results, all without human intervention. Adam was equipped with a database on genes that are known to be present in bacteria, mice and people, so it knew roughly where it should search in the genetic material for the lysine gene in baker's yeast, Saccharomyces cerevisiae. Ross King, a computer scientist and biologist at Aberystwyth University, first created a computer that could generate hypotheses and perform experiments five years ago. 'This is one of the first systems to get [artificial intelligence] to try and control laboratory automation,' King says. '[Current robots] tend to do one thing or a sequence of things. The complexity of Adam is that it has cycles.' Adam has cost roughly $1 million to develop and the software that drives Adam's thought process sits on three computers, allowing Adam to investigate a thousand experiments a day and still keep track of all the results better than humans can. King's group has also created another robot scientist called Eve dedicated to screening chemical compounds for new pharmaceutical drugs that could combat diseases such as malaria.

Houston 2600 writes "Chicago could rake in 'at least $200 million' a year — and wipe out the entire projected deficit for 2009 — by using its vast network of redlight and surveillance cameras to hunt down uninsured motorists, aldermen were told today. The system pitched to the City Council's Transportation Committee by Michigan-based InsureNet would work only if insurance companies were somehow compelled to report the names and license plates of insured motorists. That's already happening daily in 13 states, but not here."

Z80xxc! writes "FIRST (For Inspiration and Recognition of Science and Technology) has officially announced the 2009 FIRST Robotics Competition. This competition, started by inventor Dean Kamen, encourages high-school students to design and build robots to compete with and against other FRC teams. The competition overview video is available from NASA. This year's competition is called 'Lunacy.' The game consists of a series of 135-second face-offs during which the student-designed robots must pick up 9-inch game balls and deposit them in trailers hitched to the opposing teams' robots. The game field is coated with regolith, a slick polymer material, and special wheels are used to create a low-traction interaction with the crater's surface. Together, these combine to simulate the one-sixth gravity on the surface of the moon. For any readers who are interested in participating, FRC teams can always use more adult mentors."

Meshach writes "Ars Technica has an interesting run-down on the major open source victories of 2008. Some, like Firefox 3, we can probably mostly agree on. Others — KDE 4 comes to mind — will be more controversial. And Mono 2? What else should be on the list?"

An anonymous reader writes "ZDNet's Adrian Kingsley-Hughes tested the latest Win7 build against XP and Vista and came to a surprising conclusion: Win7 performs better than the other 2 OSs in the vast majority of the 23 tasks tested. Even installation. 'Rather than publish a series of benchmark results for the three operating systems (something which Microsoft frowns upon for beta builds, not to mention the fact that the final numbers only really matter for the release candidate and RTM builds), I've decided to put Windows 7, Vista and XP head-to-head in a series of real-world tests...'" This review shows only a 1-2-3 ranking for each test, so there's no sense of the quantitative level of improvement.

dj writes "NASA has designed a mission to map the boundary of the solar system. The mission is called IBEX (Interstellar Boundary Explorer) and it is ready to launch. The data collected by IBEX will allow scientists to understand the interaction between our Sun and the galaxy for the first time. Understanding this interaction will help us protect future astronauts from the danger of galactic cosmic rays." The IBEX Launch Blog will go active "about 2 hours before launch scheduled for 1:48 p.m. EDT," and the Southwest Research Institute will be running webcasts of the event. The IBEX fact sheet provides more details about the mission (PDF). IBEX will reach space via a Pegasus rocket launched from an L-1011 "Stargazer" carrier plane. You can see the launch countdown schedule at NASA's site.

PatrickByrne writes "This is The Register's world-class investigative piece concerning one aspect of the meltdown on Wall Street ('naked short selling') and how the criminals engaged a journalist to distort Wikipedia to confuse the discourse. The article explicitly and formally accuses a well-known US financial journalist, Gary Weiss, of lying about his efforts to distort a Wikipedia page under assumed names, and accuses the Powers That Be in Wikipedia (right up to and including Jimbo Wales) of complicity in protecting Weiss. This is not another story about a 15-year-old farm kid in Iowa pretending to be a professor. This is like the worst Chomskian view of Elites manipulating mass opinion. But it is all documented." We discussed the alleged Wikipedia manipulation when The Register first wrote about it last December. The submitter is the CEO of Overstock.com and a major player in this drama from the beginning.

Forbes is running a story examining the possibility of Google becoming a games publisher. The launch of their Google Lively 3D world and the acquisition of in-game advertiser AdScape has analysts speculating on whether Google will use its enormous reach to tap into the lucrative games market. "Google also has several existing technologies that could be used to create games. Imagine a flight simulator that uses Google Earth as a backdrop or tracking a spy in a major city via Google Maps' street view. While there would still be significant work required to create a game using these tools, the underlying technology is already fundamentally finished."

Lucas123 writes "After Iran's first attempt to launch a satellite on Sunday fell noticeably short of the Earth's atmosphere (though Iran claimed it made it into orbit), government officials stated they intend to put a man into space within 10 years. The long-range ballistic technology used to put satellites into space can also be used for launching weapons. Iran says it has no intention to use the technology for launching nuclear warheads."
