Matt Asay points out a recent update to VLC as they narrow in on a 1.0 release. Already a favorite of many, the open source project has made great strides in recent history towards really solidifying the position as best-in-class. This update, 0.9.9, fixes several display bugs and sees some definite performance improvements. "If you've yet to try VLC, do so. Whether you just want to play media files or also want to convert them, VLC can handle just about anything you throw at it. When all other media players fail, whether on Windows, Linux, or the Mac, VLC will almost always deliver. You can download VLC media player 0.9.9 here. It's open source, but that's not why you'll want to keep using it. You'll use it because it's better than its proprietary peers — by a long stretch.

Ellis D. Tripp writes "DC District Court judge Reggie Walton has finally ruled in the 9-year old court case pitting the model rocketry community against the US Bureau of Alcohol, Tobacco, Firearms and Explosives. The ruling is a 'slam dunk' for the rocketry community, stating that the BATFE ignored scientific evidence and overstepped its bounds by classifying ammonium perchlorate composite propellant (APCP) as an 'explosive.' Effective immediately, the BATFE has no legal jurisdiction over hobby rocket motors, and a federal Low Explosives User's Permit will no longer be needed in order to purchase APCP motors. The full text of the Judge's decision is reproduced at the link."

We recently discussed the perspective that the harrowing of Wall Street was caused by over-reliance on computer models that produced a single number to characterize risk. Wired has a piece profiling David X. Li, the quant behind the formula that enabled the creation of such simple risk models. "For five years, Li's formula, known as a Gaussian copula function, looked like an unambiguously positive breakthrough, a piece of financial technology that allowed hugely complex risks to be modeled with more ease and accuracy than ever before. With his brilliant spark of mathematical legerdemain, Li made it possible for traders to sell vast quantities of new securities, expanding financial markets to unimaginable levels. His method was adopted by everybody from bond investors and Wall Street banks to ratings agencies and regulators. ... [T]he real danger was created not because any given trader adopted it but because every trader did. In financial markets, everybody doing the same thing is the classic recipe for a bubble and inevitable bust."

Glyn Moody writes "The February 2009 Netcraft survey is not the usual 'Apache continues to trounce Microsoft IIS' story: there's a new entrant — from China. 'This majority of this month's growth is down to the appearance of 20 million Chinese sites served by QZHTTP. This web server is used by QQ to serve millions of Qzone sites beneath the qq.com domain.' What exactly is this QZHTTP, and what does it all mean for the world of Web servers?"
