Submission + - Valve Reevaluates Episodic Gaming

Submitted by Dr. Eggman
Dr. Eggman writes: CVG has a recent article on Valve and it's Episodic Game plan. According to the article after the third episode's out, Valve plans to sit down with the community and figure out what's working and what's not. Newell also wants to spend time with Telltale Games and Blizzard, both developers of episodic and episodic-like game content. The question is: monolithic game development like Half-Life 2 or Episodic development like the trilogy. "We just want to sit down with three examples in front of us and talk it over with gamers to find out what they would like us to do next."

Numerically Approximating the Wave Equation? 260

Posted by kdawson from the tools-of-an-arcane-trade dept.
ObsessiveMathsFreak writes "I'm an applied mathematician who has recently needed to obtain good numerical approximations to the classic second-order wave equation, preferably in three space dimensions. A lot of googling has not revealed much on what I had assumed would be a well-studied problem. Most of the standard numerical methods, finite difference/finite element methods, don't seem to work very well in the case of variable wave speed at different points in the domain, which is exactly the case that I need. Are any in this community working on numerically solving wave equation problems? What numerical methods do you use, and which programs do you find best suited to the task? How do you deal with stability issues, boundary/initial values, and other pitfalls? Are there different methods for electromagnetic wave problems? Finally, when the numbers have all been crunched, how do you visualize your hard-earned data?"

Submission + - Most Powerful Star Explosion Observed

Submitted by necro81
necro81 writes: The NY Times is reporting a discovery from a team of researchers about observations of the cataclysmic explosion of a 100- to 200-solar-mass star — the brightest stellar explosion ever observed. The researchers believe that the explosion is similar to the death spasms of the first stars in the universe. Rather than create a black hole, the super-massive star's collapse is believed to have been so energetic as to create unstable electron-positron pairs that tore the star apart before it could collapse into a black hole — seeding the universe with heavier elements.

You Can Oppose Copyright and Support Open Source 378

Posted by kdawson from the point-counterpoint dept.
kfogel writes "I'm submitting 'Supporting Open Source While Opposing Copyright' as a response to Greg Bulmash's piece from yesterday. I think there were a number of flaws and mistaken assumptions in Bulmash's reasoning, and I've tried to address them in this rebuttal, which has undergone review from some colleagues in the copyright-reform community."

Heuristics are bug ridden by definition. If they didn't have bugs, then they'd be algorithms.
