Groklaw Shifts Gears, Now Stressing Preservation 123

dan of the north notes a change of direction at Groklaw. Pamela Jones (PJ) writes: "I think we need to use this time to perfect our work and ensure Groklaw's preservation. It will require shutting down the daily articles and News Picks, at least for the forseeable future, but I'm convinced it's important to do it. One of the core purposes of Groklaw has always been to create a reliable record for historians and law schools to use our materials to teach and inform. ... I choose to make sure our work as fully reliable, comprehensive and, to the degree humanly possible, permanent. ... Groklaw's collection of materials is really valuable. I'd like to ensure that it survives. ... We've covered the SCO litigations since May of 2003, and it's the only complete record of this important phase in IT history."

Dr. Dobb's Journal Going Web-Only 233

paleshadows writes "The first issue of Dr. Dobb's Journal (DDJ) was published in January 1976. A few days ago, Herb Sutter (the chair of the ISO C++ committee and a long-time DDJ columnist) announced through his latest blog post that, 'as of January 2009, Dr. Dobb's Journal is permanently suspending print publication and going web-only.' This follows an earlier announcement that PC Magazine is to become digital-only, too, as of February 2009. To those of us who enjoy reading such stuff away from the computer these are bad news, as there seems to be no other major technical programmers' magazines left standing."

Are My Ideas Being Stolen? If So, What Then? 508

BinaryGrind writes "I just got started taking Computer Science classes at my local university and after reading Universities Patenting More Student Ideas I felt I needed to ask: How do I tell if any of my projects while attending classes will be co-opted by my professors or the university itself and taken away from me? Is there anything I can do to prevent it from happening? What do I need to do to protect myself? Are there schools out there that won't take my work away from me if I discover TheNextBigThing(TM)? If it does happen is there anything I can do to fight back? The school I'm attending is Southern Utah University. Since it's not a big university, I don't believe it has a big research and development department or anything of that ilk. I'm mostly wanting to cover my bases and not have my work stolen from me."

FreeBSD 7.1 Released 324

Sol-Invictus writes "The FreeBSD Release Engineering Team is pleased to announce the availability of FreeBSD 7.1-RELEASE. This is the second release from the 7-STABLE branch which improves on the functionality of FreeBSD 7.0 and introduces some new features. Some of the highlights: The ULE scheduler is now the default in GENERIC kernels for amd64 and i386 architectures. The ULE scheduler significantly improves performance on multicore systems for many workloads. Support for using DTrace inside the kernel has been imported from OpenSolaris. DTrace is a comprehensive dynamic tracing framework. A new and much-improved NFS Lock Manager (NLM) client. Boot loader changes allow, among other things, booting from USB devices and booting from GPT-labeled devices. KDE updated to 3.5.10, GNOME updated to 2.22.3. DVD-sized media for the amd64 and i386 architectures."

How the City Hurts Your Brain 439

Hugh Pickens writes "The city has always been an engine of intellectual life and the 'concentration of social interactions' is largely responsible for urban creativity and innovation. But now scientists are finding that being in an urban environment impairs our basic mental processes. After spending a few minutes on a crowded city street, the brain is less able to hold things in memory and suffers from reduced self-control. 'The mind is a limited machine,' says psychologist Marc Berman. 'And we're beginning to understand the different ways that a city can exceed those limitations.' Consider everything your brain has to keep track of as you walk down a busy city street. A city is so overstuffed with stimuli that we need to redirect our attention constantly so that we aren't distracted by irrelevant things. This sort of controlled perception — we are telling the mind what to pay attention to — takes energy and effort. Natural settings don't require the same amount of cognitive effort. A study at the University of Michigan found memory performance and attention spans improved by 20 percent after people spent an hour interacting with nature. 'It's not an accident that Central Park is in the middle of Manhattan,' says Berman. 'They needed to put a park there.'"

Setting a Learning Curve In MMOs 156

Ten Ton Hammer has an article looking at the learning curves of modern MMOs. Many of the more popular games, such as World of Warcraft, go to great lengths to make learning the game easy for new players. Others, such as EVE Online, have had success with a less forgiving introduction. But to what extent do the most fundamental game mechanics limit the more complex end-game play? "The current trend in MMOG's appears to be make the game so easy and interest-grabbing right out of the gate that even a person with the attention span of a monkey chewing on a flyswatter will be able to keep up and get into the swing of things. Depth of game mechanics is still possible with a system like this, but it needs to be introduced not only clearly, but later in the game, after a player has played enough to be hooked and is willing to put in some extra time to learn about the more intricate game mechanics available to them."

Carefully Timed Jerks Could Power Space Elevator 270

Hugh Pickens writes "BBC has an interesting article on the long-standing issue of how to power the 'climber' that would ascend a space elevator into space. Previous ideas have included delivering microwave or laser power to the climber beamed from the Earth's surface, but now European Space Agency ground station engineer Age-Raymond Riise has demonstrated a device that could provide a "lift into space" for cheaper space missions along a 100,000-km long tether anchored to the Earth. Riise demonstrated sending power mechanically by providing carefully timed jerks of the cable at its base with a broomstick to represent the cable held in tension, an electric sander to provide a rhythmic vibration to the bottom of the stick, and three brushes representing the climber with their bristles pointing downwards allowing the climber assembly to slide upward along the broomstick as it moved slightly downward, but grip it as it moved slightly upward. 'It would be possible to make a suspension system that completely decouples the cabin where the passengers are,' says Riise. 'For them it would be a linear movement with very little disturbance.' Riise says that he has been approached by commercial elevator companies, who are researching new ideas for elevators in superscrapers where the simplicity of the approach makes it attractive when compared to other ideas for powering lifts, such as compressed air."

A Hacker's Audacious Plan To Rule the Underground 313

An anonymous reader writes "Wired has the inside story of Max Butler, a former white hat hacker who joined the underground following a jail stint for hacking the Pentagon. His most ambitious hack was a hostile takeover of the major underground carding boards where stolen credit card and identity data are bought and sold. The attack made his own site, CardersMarket, the largest crime forum in the world, with 6,000 users. But it also made the feds determined to catch him, since one of the sites he hacked, DarkMarket.ws, was secretly a sting operation run by the FBI."

Distributed "Nuclear Batteries" the New Infrastructure Answer? 611

thepacketmaster writes "The Star reports about a new power generation model using smaller distributed power generators located closer to the consumer. This saves money on power generation lines and creates an infrastructure that can be more easily expanded with smaller incremental steps, compared to bigger centralized power generation projects. The generators in line for this are green sources, but Hyperion Power Generation, NuScale, Adams Atomic Engines (and some other companies) are offering small nuclear reactors to plug into this type of infrastructure. The generator from Hyperion is about the size of a garden shed, and uses older technology that is not capable of creating nuclear warheads, and supposedly self-regulating so it won't go critical. They envision burying reactors near the consumers for 5-10 years, digging them back up and recycling them. Since they are so low maintenance and self-contained, they are calling them nuclear batteries."

Ubuntu Kung Fu Screenshot-sm 253

Lorin Ricker writes "Back in the dark ages of windows-based GUIs, corresponding to my own wandering VMS evangelical days, I became enamored of a series of books jauntily entitled Xxx Annoyances (from O'Reilly & Assocs.), where "Xxx" could be anything from "Windows 95", "Word", "Excel" or nearly piece of software which Microsoft produced. These were, if not the first, certainly among the most successful of the "tips & tricks" books that have become popular and useful to scads of hobbyists, ordinary users, hackers and, yes, even professionals in various IT pursuits. I was attracted, even a bit addicted, to these if only because they offered to try to make some useful sense out of the bewildering design choices, deficiencies and bugs that I'd find rampant in Windows and its application repertory. Then I found Keir Thomas, who has been writing about Linux for more than a decade. His new "tips" book entitled, Ubuntu Kung Fu — Tips & Tools for Exploring Using, and Tuning Linux, and published by Pragmatic Bookshelf, is wonderful. Having only recently wandered into the light of Linux, open source software, and Ubuntu in particular, this book comes as a welcome infusion to my addiction." Read below for the rest of Lorin's review.

New Method To Revolutionize DNA Sequencing 239

An anonymous reader writes "A new method of DNA sequencing published this week in Science identifies incorporation of single bases by fluorescence. This has been shown to increase read lengths from 20 bases (454 sequencing) to >4000 bases, with a 99.3% accuracy. Single molecule reading can reduce costs and increase the rate at which reads can be performed. 'So far, the team has built a chip housing 3000 ZMWs [waveguides], which the company hopes will hit the market in 2010. By 2013, it aims to squeeze a million ZMWs [waveguides] onto a single chip and observe DNA being assembled in each simultaneously. Company founder Stephen Turner estimates that such a chip would be able to sequence an entire human genome in under half an hour to 99.999 per cent accuracy for under $1000.'"

LG High-Def TVs To Stream Netflix Videos 190

DJAdapt writes to tell us that LG has launched a new line of high definition TVs that will be capable of streaming Netflix videos with no additional hardware. This is just another in a long line of expansions from the once DVD rental service, which has expanded to the Roku set top box, Xbox 360, PC, Mac, and Linux platforms recently. "Piping movies directly to TV sets is the natural evolution of the video streaming service, said Reed Hastings, the chief executive of Netflix. "The TV symbolizes the ultimate destination," he said. That idea -- shared by Sony Corp., which already streams feature films and TV shows directly to its Bravia televisions -- is still in its early stages. Netflix's streaming service taps a library of 12,000 titles, while the company's DVD menu numbers more than 100,000 titles. Hastings expects that gap will "definitely narrow" over time, but he noted that DVDs maintain an advantage over streaming, which is that "they are very profitable" for film studios."

The Perils of Simplifying Risk To a Single Number 286

A few weeks back we discussed the perspective that the economic meltdown could be viewed as a global computer crash. In the NYTimes magazine, Joe Nocera writes in much more depth about one aspect of the over-reliance on computer models in the ongoing unpleasantness: the use of a single number to assess risk. Reader theodp writes: "Relying on Value at Risk (VaR) and other mathematical models to manage risk was a no-brainer for the Wall Street crowd, at least until it became obvious that the risks taken by the largest banks and investment firms were so excessive and foolhardy that they threatened to bring down the financial system itself. Nocera explores the age-old debate between those who assert that the best decisions are based on quantification and numbers, and those who base their decisions on more subjective degrees of belief about the uncertain future. Reliance on models created a 'false sense of security among senior managers and watchdogs,' argues Nassim Nicholas Taleb, who likens VaR to 'an air bag that works all the time, except when you have a car accident.'"

The Exact Cause of the Zune Meltdown 465

An anonymous reader writes "The Zune 30 failure became national news when it happened just three days ago. The source code for the bad driver leaked soon after, and now, someone has come up with a very detailed explanation for where the code was bad as well as a number of solutions to deal with it. From a coding/QA standpoint, one has to wonder how this bug was missed if the quality assurance team wasn't slacking off. Worse yet: this bug affects every Windows CE device carrying this driver."
