Baldrson writes "If you think you can compress a 100M sample of Wikipedia better than paq8f, then you might want to try winning win some of a (at present) 50,000 Euro purse. Marcus Hutter has announced the Hutter Prize for Lossless Compression of Human Knowledge the intent of which is to incentivize the advancement of AI through the exploitation of Hutter's theory of optimal universal artificial intelligence. The basic theory, for which Hutter provides a proof, is that after any set of observations the optimal move by an AI is find the smallest program that predicts those observations and then assume its environment is controlled by that program. Think of it as Ockham's Razor on steroids. Matt Mahoney provides a writeup of the rationale for the prize including a description of the equivalence of compression and general intelligence."

The Interfacer writes "Cray and the U.S. Department of Energy (DOE) Office of Science announced that Cray has won the contract to install a next-generation supercomputer at the DOE's National Energy Research Scientific Computing Center (NERSC). The systems and multi-year services contract, valued at over $52 million, includes delivery of a Cray massively parallel processor supercomputer, code-named 'Hood.'"

Kalak writes "IBM's motion to limit SCO's claims to those that have specific version, file and line numbers has been granted, in part. At the end of last year, SCO made 294 allegations. IBM asked for dismissal of 198 of them due to lack of this information, 1 SCO withdrew, 1 IBM withdrew from the request, and 185 of them have been dismissed from the case. This leaves 107 of the charges are left to be addressed by means other than lack of specificity (such as public domain, BSD code, who owns it, etc.) As usual, Groklaw, has discussion, as well as the Order and an excellent chart of the history of alleged violations has been created as well."

Roland Piquepaille writes "It's not the first time that animal brain cells have been used in conjunction with nanoparticles. But now, a team of Israeli researchers have grown self-organizing networks of rat brain cells by binding them to carbon nanotubes. In a short article, New Scientist reports that these neural networks are remarkably stable, surviving for almost three months in the lab. These hybrid networks could be used in future biological sensors. For example, they could identify a poison by measuring its effect on such a network of brain cells."

georgewilliamherbert writes "The latest installment of "As the PDF Blackouts Turn" hit today, with a U.S. government apparently releasing a redacted version of their court filing in the Balco grand jury leak case which merely stuck a black line over the text, which remains available in the document. As with prior documents, entering text cut/paste mode in a normal PDF browser such as Acrobat allows a reader to access the concealed text. Previous incidents include an AT&T filing in the NSA case." This works with Xpdf and KPDF, too; for KPDF, use the selection tool (under the Tools menu) around the redacted section, copy to clipboard, then paste into the text-manipulator of your choice.

venkatg writes "Soon after Apple introduced sudden motion sensors in their PowerBooks in early 2005, Amit Singh had shown how these sensors can be used for creative purposes (covered by Slashdot earlier as Having Fun With PowerBook Motion Sensors and PowerBook As A New Kind Of Human Interface Device). This time around Singh discusses 'Experimenting With Light' in a new article whereby by light he means the ambient light sensors and the illuminated backlight keyboard sensors in Apple's laptops. The article shows (source code is included) how one can measure ambient light and do things with it. It also shows things like how to get/set illuminated keyboard brightness and display brightness or do fade transitions of the keyboard lighting. So now that we have all these motion and light sensors under control, is there a MacBook discotheque in the works?"

MSTCrow5429 writes to mention an article published by WorldNetDaily attacking the policies and actions of Google News. The author takes issue with the practice of removing sites that offer very frank discussions about radical Islam and terrorism as "hate speech." Several sites have complained about removal including The Jawa Report, MichNews, and most recently The New Media Journal. In the termination email to The New Media Journal Google cited several stories as objectionable in order to further explain the action.

Mike Barton writes to tell us InfoWorld is reporting IBM has announced that the upcoming version of Lotus Notes, due out this fall, will feature an "ODF-compatible version of OpenOffice embedded in the Notes e-mail application." IBM hopes that this large scale distribution of the ODF standard will help bolster their foothold in the marketplace since "standards live or die on how many people use them"

An anonymous reader writes "Slowing down light used to be considered a neat trick for physics wonks. But researchers in New York now say they've pushed light into reverse. And as if to defy common sense, the backward-moving light travels faster than light." While there's not much use to come of it yet, it will be interesting if Einstein himself is proved wrong.

bariswheel writes "In a paper co-authored by the Microkernel Maestro Andrew Tanenbaum, the fragility of modern kernels are addressed: "Current operating systems have two characteristics that make them unreliable and insecure: They are huge and they have very poor fault isolation. The Linux kernel has more than 2.5 million lines of code; the Windows XP kernel is more than twice as large." Consider this analogy: "Modern ships have multiple compartments within the hull; if one compartment springs a leak, only that one is flooded, not the entire hull. Current operating systems are like ships before compartmentalization was invented: Every leak can sink the ship." Clearly one argument here is security and reliability has surpassed performance in terms of priorities. Let's see if our good friend Linus chimes in here; hopefully we'll have ourselves another friendly conversation."

sfeinstein writes "Power companies using dynamic pricing models to charge more for electricity during hours of peak usage is nothing new. Now, however, one company has decided to take advantage of this by using technology to buy (and store) capacity when rates are low and use that capacity when rates are at their highest." From the article: "The device, called GridPoint Protect, is the size of a small file cabinet and connects to the circuitbreaker panel. (The company also offers a lower-capacity version designed for homes, which costs $10,000.) A built-in computer powered by a Pentium chip will make intelligent purchase decisions, buying when prices are low, then storing the electricity for later use. That will make it possible to run your company during the workday with cheaper electricity that you purchased at 3 A.M."

An anonymous reader writes "The Register is reporting that a new start-up, DRC Computer, has created a reprogrammable co-processor that can slot directly into Opteron sockets. This new product has the potential to boost the Opteron chips well ahead of their Xeon-based competition. From the article: 'Customers can then offload a wide variety of software jobs to the co-processor running in a standard server, instead of buying unique, more expensive types of accelerators from third parties as they have in the past.'"

Spongeform writes "eWeek has an interview with a Microsoft security official admitting to hiding details on software vulnerabilities that are discovered internally. The reason? Microsoft believes that full disclosure of every security-related product change only serves to aid attackers. However, companies using host-based IPS that rely on flaw information to build signatures are basically left at risk because of Microsoft's silent fixes."

RareButSeriousSideEffects writes "Techdirt reports that 'Newest Commissioner Deborah Tate has apparently announced that while she knows its outside the FCC's authority, she's a huge fan of copy protection and hopes to use her new position as a "bully pulpit" on the topic.'"

OSS_ilation writes "While much has been said about Novell or Red Hat as potential targets for Oracle this week, there are some in the Linux community who believe a different distro might deserve the attention of Larry Ellison. That distribution is Ubuntu, and analysts like Burton Group's Richard Monson-Haefel believed that it would be a better fit for Oracle, which is looking only for an OS and not for any of the baggage associated with Novell, like Netware. Ubuntu, with its huge community base and version 6.06 on the way, could be the perfect fit, he said."
