An anonymous reader writes "gNewSense, the fully-free GNU/Linux distribution sponsored by the FSF, has released a 2.1 live CD (torrent). Since the last release, more non-free binary blobs have been removed, new artwork has been added and lots of other improvements have been made. It's also two years since the first edition of gNewSense, and in that time an impressive ten live CDs have been released! gNewSense 2.1 DeltaH is based on Ubuntu Hardy, and removes non-free software that other distributions don't." I wonder if gNewSense can be easily installed on an OLPC XO the way several other distros can.

Riding with Robots writes "As previously reported, the robotic spacecraft Cassini recently flew through the mysterious geyser plumes at Saturn's icy moon Enceladus. Today, NASA released the preliminary results of the flyby, including some intriguing findings, such as organic materials 20 times denser than expected and relatively high temperatures along the fissures where the geysers emanate. 'These spectacular new data will really help us understand what powers the geysers. The surprisingly high temperatures make it more likely that there's liquid water not far below the surface,' said one mission scientist."

simoniker writes "In a new weblog post on Dobbs Code Talk, Intel's James Reinders discusses the growth of concurrency in programming, suggesting that '...programming for multi-core is catching the imagination of programmers more in Japan, China, Russia, and India than in Europe and the United States.' He also comments: 'We see a significantly HIGHER interest in jumping on a parallelism from programmers with under 15 years experience, verses programmers with more than 15 years.' Any anecdotal evidence for or against from this community?"

Kinescope writes "The motion picture industry has said that its profits are at risk due to piracy, but a record-setting 2007 box office has some wondering if the industry is crying 'wolf.' Last year, the US box office totaled $9.63 billion, a 5.4% increase over 2006. 'Piracy is so bad, according to the MPAA, that we need special legislation to target the dastardly college pirates who are destroying the business. It's so bad that Weekly Reader subscribers will learn about the $7 billion a year "lost" to Internet piracy. It's so bad that the MPAA wants ISPs to ignore years of common carrier law and the promises of "safe harbor" and start filtering their traffic, looking for copyright violations. The real world isn't quite this simple, of course. It turns out that the MPAA's college numbers were off by a factor of three, a revelation that came after years of hiding the study's methodology but continuing to lobby Congress with its numbers.'"

Several readers sent us the story of three high school sophomores in Racine, Wisconsin who were just notified that a celestial body they had discovered during a science project has been verified as an asteroid. The students at Racine's Prairie School will be given the opportunity to name the asteroid in about four years. They used a telescope in New Mexico, belonging to a college in Michigan, that they controlled over the Net.

DancingFountain writes "If you have taken a college chemistry class, you may have seen this fantastic demonstration. When two clear liquids are mixed, they immediately turn yellow, and then undulate back and forth between blue-black and yellow in a mesmerizing display. Wired Science explains that the reaction, which was developed by two high school science teachers, has been rigorously studied but not fully explained."

kramed8 writes "As a student myself, after reading the recent 'Slam' article on Java I really began to be concerned with the path of my education. I am currently attending a small Canadian University as a 3rd year Computer Science and Business student set to graduate next year. What seems to have troubled me from reading the article and user comments is that I do not feel as confident as I want to be in C, ASM and other related low-level programming topics. I was taught C++ in my introductory courses, with subsequent classes using C# or Java. My education has not been particularly difficult or time consuming to get good grades, so I have spent my free time dabbling in topics and languages that interest me (ie Multiple GUI Toolkits, Python, Linux). How can I spend my free time in the next year to prepare to enter the work place with a proper toolbox of skills? From what I have been told, there are more jobs for Java and Data Warehouse development teams compared to lower-level programmers. As an undergrad, what skills should I be trying to attain now to further my employability in the future?"

An anonymous reader writes "Mobile phones with built-in mini projectors will launch later this year, according to 3M, which gave PC Pro a hands-on demonstration of the technology at CES 2008. The projector has a brightness of around 8-10 lumens, and is capable of displaying an image of up to 50 in., although 3M's spokesperson Greg Roberts told us that, with perfect lighting conditions, it's possible to squeeze a 60-in. screen out of the projector."

An anonymous reader brings us this article from Wired about a new method to produce fuel with the help of concentrated sunlight and carbon dioxide. The process "reverses" combustion, breaking down the CO2 into carbon monoxide, which is then used as a building block for hydrocarbons. Quoting: "The Sandia team envisions a day when CR5s are installed in large numbers at coal-fired power plants. Each of them could reclaim 45 pounds of carbon dioxide from the air daily and produce enough carbon monoxide to make 2.5 gallons of fuel. Coupling the CR5 with CO2 reclamation and sequestration technology, which several scientists already are pursuing, could make liquid hydrocarbons a renewable fuel."

DaMan writes "ZDNet takes Firefox 3.0 beta 2 for a spin and draws some conclusions that should be sweet music to Mozilla's ears. "Beta 2 feels snappier and far more responsive than beta 1 (or Firefox 2.0 for that matter) and I can feel the difference on all the systems that I've tried it on — from a lowly Sempron system to my quad-core monsters. No matter what you want doing — opening a new tab, moving tabs, opening up Find, zooming in and out of the page, bookmarking — it all happens swiftly and smoothly. What surprises me about the Firefox 3.0 beta is how many memory leaks that Mozilla have fixed. Complaints of memory leaks with Firefox 2.0 were met with an attitude of "Leaks? What leaks?" Considering that there have been more than 300 leaks plugged, it's obvious that past versions leaked like sieves.""

I Don't Believe in Imaginary Property writes "HP and Staples are facing an anti-trust lawsuit over replacement printer cartridges. According to the lawsuit, HP paid Staples $100 million to refuse to stock competing ink cartridges. HP could make that back in short order when you consider that printer ink can cost $8,000 per gallon and certain printers deceive users to waste as much as 64% of their ink."

Smivs writes "The BBC reports that an ocean may not be the source of the jets emanating from Saturn's moon Enceladus. Controversial research questions the moon's promise as a target in the search for life beyond Earth. A chemical analysis of Enceladus, led by University of Colorado planetary scientist Nick Schneider, failed to detect sodium, an element scientists say should be present in any body of water that has been in contact with rock for billions of years. Spectral analysis with the Keck Telescope found no sodium in the plumes or in the vapor in orbit around the moon. At stake is whether Saturn's moon could support alien life and is thus a worthy target for a NASA exploratory mission to detect it. Such a mission to Enceladus is one of four currently under review for further development."

Jamie noted that ruby on rails 2.0 is done. In addition to upgrade and installation instructions, the article lists a number of the more interesting new features in the release which appears to be quite extensive.

coondoggie writes "A new open source mathematics program is looking to push aside commercial software commonly used in mathematics education, in large government laboratories and in math-intensive research. The program's backers say the software, called Sage, can do anything from mapping a 12-dimensional object to calculating rainfall patterns under global warming."
