Theora Ahead of H.264 In Objective PSNR Quality 313

bigmammoth writes "Xiph hackers have been hard at work improving the Theora codec over the past year, with the latest versions gaining on and passing h.264 in objective PSNR quality measurements. From the update: 'Amusingly, it also shows test versions of Thusnelda pulling ahead of h.264 in terms of objective quality as bitrate increases. It's important to note that PSNR is an objective measure that does not exactly represent perceived quality, and PSNR measurements have always been especially kind to Theora. This is also data from a single clip. That said, it's clear that the gap in the fundamental infrastructure has closed substantially before the task of detailed subjective tuning has begun in earnest.' Momentum is building with a major Open Video Conference in June, the impending launch of Firefox 3.5 and excitement about wider adoption in a top-4 web site. It's looking like free video codecs may pose a serious threat to the h.264 bait-and-switch plan to start charging millions for internet streaming of h.264 in 2010."

Ethical Killing Machines 785

ubermiester writes "The New York Times reports on research to develop autonomous battlefield robots that would 'behave more ethically in the battlefield than humans.' The researchers claim that these real-life terminators 'can be designed without an instinct for self-preservation and, as a result, no tendency to lash out in fear. They can be built without anger or recklessness ... and they can be made invulnerable to ... "scenario fulfillment," which causes people to absorb new information more easily if it agrees with their pre-existing ideas.' Based on a recent report stating that 'fewer than half of soldiers and marines serving in Iraq said that noncombatants should be treated with dignity and respect, and 17 percent said all civilians should be treated as insurgents,' this might not be all that dumb an idea."

Web Singletons? 254

tcmb writes "There are an uncounted number of web mail and picture sharing services, there are more than enough web sites for online bookmark management and friend-finding, but as far as I know there is only one Internet Archive. Which are the true web singletons, services that exist only once in this form?" And does anything approach the singular time-wasting abilities of IMDB or Wikipedia?

Journal Journal: Ending Email as we know it

I spent (or was it wasted?) some time the other day reading the comments to the Another Millionaire Spammer Story posted on Friday. I don't think I get too much more spam than anybody else, and I get considerably less than other people, but something about the behavior of these sort of people just drives me nuts.
