Using an evolutionary algorithm and the ears of you the general public, we've been evolving a four bar loop that started out as pretty dismal primordial auditory soup and now after >27k ratings and 200 generations is sounding pretty good. Given that the only ingredients are sine waves, we're impressed. We got some coverage in the New Scientist CultureLab blog but now things have gone quiet and we'd really appreciate some Slashdotter idle time. We recently upped the maximum 'genome size' and we think that the music is already benefiting from the change."

A feature at Gamasutra examines one of the foundations of many MMORPGs — the idea that class roles within such a game fall into three basic categories: tank, healer, and damage dealer. The article evaluates the pros and cons of such an arrangement and takes a look at some alternatives. "Eliminating specialized roles means that we do away with boxing a class into a single role. Without Tanks, each class would have features that would help them participate in and survive many different encounters like heavy armor, strong avoidance, or some class or magical abilities that allow them to disengage from direct combat. Without specialized DPS, all classes should be able to do damage in order to defeat enemies. Some classes might specialize in damage type, like area of effect (AoE) damage; others might be able to exploit enemy weaknesses, and some might just be good at swinging a sharpened bit of metal in the right direction at a rapid rate. This design isn't just about having each class able to fill any trinity role. MMO combat would feel more dynamic in this system. Every player would have to react to combat events and defend against attacks."

dido writes "Princeton University geology Professor Kenneth Deffeyes has been studying world petroleum production data and has come to the conclusion that the world hit peak oil last December 16, 2005. If he is correct, total world oil production will never surpass what was produced last December. From the article: 'Compared to 2004, world oil production was up 0.8 percent in 2005, nowhere near enough to compensate for a demand rise of roughly 3 percent. The high prices did not bring much additional oil out of the ground. Most oil-producing countries are in decline."

Oil -- and energy in general -- has long been a big topic among Slashdot readers. Predictions about The End of the Age of Oil (about which, claims the subtitle, this book provides "all you need to know") certainly are not new -- and if civilization lasts long enough, one day they'll prove true. It's nice to consider that automobiles aren't necessarily tied to petroleum, but mine certainly runs on 87 octane gasoline, and there aren't enough turkey guts or grease to power everything that we use petro-fuels for right now (though places like Iceland are trying hard to tap other sources). Current gas prices (in the U.S. at any rate) are higher than they have been in a decade or so, but in constant dollars, gasoline prices have certainly been worse. How much to panic, and when? Read on below for Arthur Smith (apsmith)'s brief review of David Goodstein's Out of Gas for a rather gloomy look at the future of oil-based energy.
