Internet game provides breakthrough in predicting the spread of epidemics
Thursday, February 2, 2006, 02:09 PM - Games
Searching for a way to model the modern spread of disease became the focus of discussions among the co-authors: Theo Geisel, director of the Max Planck Institute for Dynamics and Self Organization and professor at the University of Goettingen; Dirk Brockmann, a postdoctoral fellow at the Max Plank Institute for Dynamics and Self Organization; and Hufnagel. Following a conference in Montreal, Brockmann met with a friend in Vermont, a cabinetmaker, who showed him the internet game for tracking the movement of dollar bills, located at www.wheresgeorge.com. Participants can register a dollar bill, of any denomination, and monitor its geographic circulation.
The physicists were intrigued: Like viruses, money is transported by people from place to place. They found that the human movements follow what are known as universal scaling laws (from local to regional to long-distance scales). Using the game data, they developed a powerful mathematical theory that describes the observed movements of travelers amazingly well over distances from just a few kilometers to a few thousand. The study represents a major breakthrough for the mathematical modeling of the spread of epidemics.

FAIRYLAND was in turmoil. During a tech rehearsal for the October 2004 Off Off Broadway production of "Tam Lin" — a play about a clash between mortal and immortal worlds — a real-life clash threatened to derail the show. Exactly what happened has become, literally, a federal case, and the sides agree on very few details. Did the playwright, Nancy McClernan, insist that the director's staging was incompetent? Did the director, Edward Einhorn, refuse to alter it? Did the producer, Jonathan X. Flagg, smash some furniture on the set? One thing's clear: the morning after the tech rehearsal, after two months of unpaid work, Mr. Einhorn was fired.
Please learn how everything could have been different if only some people had given away a few dollars on time. Around $3M.

Protecting stuff comes from fear. Believing that someone is out to take it, raises the question of what led you to the conclusion that whatever it is has such a potential for destroying your way of life? And since you have reached this conclusion, where did the idea come from to put it on the web?

Hollywood to Google (on video over IP): don't take it away from me!

Major article from the consultant office i2 Partners War of the Worlds: Hollywood Opts Out of the 'Google Economy':
Hollywood believes large-scale broadband video distribution would only destroy proven value, fail to provide alternative value, and alter a business model that is still far from being in decline. With near-total control of the most valuable program libraries and the business models governing their distribution, a shift towards broadband media will come largely on Hollywood’s terms and at an incremental pace.

The new GPL (beta)

The Free Software Foundation has finally released the draft for the third version of the famous GPL license. As Neco points out there is:
1. This website lists a wdiff -the find-the-seven-differences tool- between the old and the prospective new version.
2. Uwe Hermann also linked a wiki and a comment site where users can give feedback.
3. There is also a rationale document which explains the changes and the contents.

the apple fairytale of the twice-as-fast Intel chip

DesScorp writes "In Tom Yager's Enterprise Mac column at InfoWorld, he says that "Apple has bought itself another controversy, and once again, needlessly". In a nutshell, he says Apple used multi-processor benchmarks to skew performance comparisons between the new Intel Macs and the PowerPC versions.
Apple uses SPEC*_rate2000 tests as a foundation for claims that Intel-based Macs outperform PowerPC G4 and G5 by a factor of 2 to 5. Well, yeah. A dual-core anything outperforms a single-core anything else by a factor of 2 to 5 in benchmark tests that make use of multiple threads or processes, tests crafted specifically for the purpose of stressing SMP-based systems.
Now please, all at once: dooooodgy...
