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."

eggegick writes "My wife has taken a number of college courses over the last three years and many of the classes used on-line materials rather than books. The problem was these required IE along with Java, Active X and/or various plug-ins (the names of which escapes me), and occasionally I'd have to tweak our firewall to allow these apps to run. I don't think any of these training apps would work with Firefox. All of this made me cringe from a security point of view. Myself, I use Firefox, No-Script, our external firewall and common sense when using the web. I have a very old Windows 2000 machine that I keep up to date. To my knowledge, I've never had a virus or malware problem. Her computer is a relatively new XP machine, and at this point she feels her computer has something wrong. But now she prefers to use my old machine instead of hers since it seems to be more responsive. We plan to run the recovery disk on hers. Assuming the college course work applications were part of the cause, what recommendations do any of you have for running this kind of software? Is there a VMware solution that would work — that is, have a Windows image that is used temporarily for the course work and then discarded at the end of the semester (and how do you create such an image, and what does it cost?)."

snydeq writes "For the past several months, Microsoft has engaged in an extended public mea culpa about Vista, holding a series of press interviews to explain how the company's Vista mistakes changed the development process of Windows 7. Chief among these changes was the determination to 'define a feature set early on' and only share that feature set with partners and customers when the company is confident they will be incorporated into the final OS. And to solve PC-compatibility issues, Microsoft has said all versions of Windows 7 will run even on low-cost netbooks. Moreover, Microsoft reiterated that the beta of Windows 7 that is now available is already feature-complete, although its final release to business customers isn't expected until November." As a data point for how well this has all worked out in practice, reader The other A.N.Other recommends a ZDNet article describing rough benchmarks for three versions of Windows 7 against Vista and XP. In particular, Win-7 build 7048 (64-bit) vs. Win-7 build 7000 (32-bit and 64-bit) vs. Vista SP1 vs. XP SP3 were tested on both high-end and low-end hardware. The conclusions: Windows 7 is, overall, faster than both Vista and XP. As Windows 7 progresses, it's getting faster (or at least the 64-bit editions are). On a higher-spec system, 64-bit is best. On a lower-spec system, 32-bit is best.

snitch writes "Last week Mozilla released Bespin, their web-based framework for code editing, and only a few days later Boris Bokowski and Simon Kaegi implemented an Eclipse-based Bespin server using headless Eclipse plug-ins. With the presentation of the web-based Eclipse workbench at EclipseCon and the release of products like Heroku, a web-based IDE and hosting environment for RoR apps, it seems that web-based IDEs might soon become mainstream."

An anonymous reader writes "Tuxradar did some benchmarks comparing Firefox's Windows and Linux JavaScript performance. 'We did some simple JavaScript benchmarks of Firefox 3.0 using Windows and Linux to see how it performed across the platforms — and the results are pretty bleak for Linux.' Later on, they tried Wine. 'The end result: Firefox from Mozilla or from Fedora has almost nil speed difference, and Firefox running on Wine is faster than native Firefox.'"

snydeq writes "The number of bugs in technical documentation for Microsoft communication protocols continues to grow, according to court documents filed for ongoing antitrust oversight of the company in the US. Problems with the technical documentation — which includes 1,660 identified bugs as of Dec. 31, up from 1,196 bugs on Nov. 30 — remain the major complaint from lawyers representing the group of 19 states that joined the US Department of Justice's antitrust lawsuit against Microsoft. Lawyers for the states have complained repeatedly that technical documentation issues are opening faster than Microsoft can close them. Nearly 800 Microsoft employees are working on the more than 20,000 pages of technical documentation, according to the court documents filed Wednesday."
