The book Halo Effect is an intriguing title that takes a look Bungie's best-selling Halo titles from a number of different angles. Each chapter includes coverage of specific elements; included are descriptions of pro events, a bit on the development process, and the making of the Red vs. Blue series. One of the most interesting chapters takes a look at the science behind the Halo world, talking about the physics and logic behind ringworlds and the hi-tech weaponry seen in the game. Thanks in part to a mini-review of the book on the GameSetWatch site, Gamasutra has been allowed to reprint the entire 'science of Halo' chapter on their website. "A 5,000 kilometer radius would yield a circumference of roughly 31,400 kilometers. If we assume a width-to-radius ratio similar to that of Niven's Ringworld, they would be approximately 5.37 kilometers wide. They are significantly wider, though, at 320 kilometers. The Halos, then, would have a surface area of 10 million square kilometers - slightly larger than the surface area of Canada, and approximately 2 percent of the surface area of Earth. Of course, since we know that there are lakes, seas, and rivers on the Halos, the livable surface area would be fractionally less."

We remain proud of OpenBSD's record of ten years with only two remote holes in the default install. As in our previous releases, 4.1 provides significant improvements, including new features, in nearly all areas of the system."

Diggers are in open revolt against the moderators and are retaliating in clever and inventive ways. At one point, the entire front page comprised only stories that in one way or another were related to the hex number. Digg users quickly pointed to the HD DVD sponsorship of Diggnation, the Digg podcast show. Search digg for HD-DVD song lyrics, coffee mugs, shirts, and more for a small taste of the rebellion." Search Google for a broader picture; at this writing, about 283,000 pages contain the number with hyphens, and just under 10,000 without hyphens. There's a song. Several domain names including variations of the number have been reserved. Update: 05/02 05:44 GMT by J : New blog post from Kevin Rose of Digg to its users: "We hear you."
