The proposed solution, arrived at by the Internet Society of China (affiliated with the ministry of information) would allow bloggers to use a pseudonym when blogging as long as they used their real name when registering."

Johnny X writes "Weird Al Yankovic recently said he makes far less money when you buy from iTunes than when you buy an actual CD. This guy did the math and showed that Weird Al could be losing up to 85% of his record sales income due to the 'weird' ways the record companies compute digital sales. Are all artists getting the shaft like this?"

hamilton76 writes to tell us that researchers at Carnegie Mellon have found a way to allow computers to extrapolate 3 dimensional models from 2 dimensional pictures. From the article: "Using machine learning techniques, Robotics Institute researchers Alexei Efros and Martial Hebert, along with graduate student Derek Hoiem, have taught computers how to spot the visual cues that differentiate between vertical surfaces and horizontal surfaces in photographs of outdoor scenes. They've even developed a program that allows the computer to automatically generate 3-D reconstructions of scenes based on a single image. [...] Identifying vertical and horizontal surfaces and the orientation of those surfaces provides much of the information necessary for understanding the geometric context of an entire scene. Only about three percent of surfaces in a typical photo are at an angle, they have found."

A few quick updates on some recent Slashdot stories in Slashback tonight. We have some additional information on the ever-interesting hundred-dollar laptop, the ongoing flap over the trademarking of 'Web 2.0' for conferences, and the shutdown of the Pirate Bay site. Read on for details.

John Callaham writes "On the eve of its release, Valve's Doug Lombardi tells FiringSquad why Half-Life 2 Episode One, their first chapter in their episodic first-person shooter, will be worth the $20." From the article: "From the creation standpoint, it's much easier to develop the story and plot via Episodic releases, as the focus is tighter by default. And since each of the HL2 Episodes are being created by a single development team, the story flow will be more cohesive as it's the work of a single body and not the collaboration of separate teams attempting to merge the different chapters after years of working separately. We are, however, keeping a very close eye on the overall story flow as we advance folks from City 17 to the adventures that lie outside the City in Episodes Two and Three."

GenieGenieGenie writes "AP is running a story about Webroot's Spy Sweeper, specifically about the competition it's facing from Vista's bundled anti-spyware. Webroot's CEO David Moll maintains that 'The taking of a second-best product in this space [i.e. Vista's Defender, f.k.a. AntiSpyware] is akin to locking half the doors in your house,' but others seem to think that if Moll doesn't want his company to become a second Netscape, it would 'ultimately [...] need to offer more than just an anti-spyware package.' The interesting issue here is whether this need for broadening the offer would be the case also for other leading companies subject to similar 'bundled-with' competition."

NewsForge (Also owned by VA) is running a short writeup on how to put MediaWiki to work for your organization. The writeup includes several addition tools that could be helpful in rounding out the overall package. From the article: " Imagine how useful it would be to have an online knowledge base that can easily be updated created by key people within your organization. That's the promise of a wiki -- a Web application that 'allows users to easily add, remove, or otherwise edit all content, very quickly and easily,' as Wikipedia, perhaps the best-known wiki, puts it. Why not bring the benefits of a wiki to your organization?"

Nyerp writes "Researchers are using naval logs dating back as far as 1590 to arrive at better estimates of the decline of Earth's magnetic field. The results suggest that there may be a reversal of earth's magnetic field in about 2000 years." Also worth noting, our ancestors have lived through a number of polar reversals, and we're still here, so no need to fret!
