Trillian_1138 writes "C-SPAN, a network in the US dedicated to airing governmental proceedings, has adopted a Creative Commons-style license for all its content. This follows the network claiming Speaker of the House Pelosi's use of C-Span videos on her site violated their copyright. Specifically, 'C-SPAN is introducing a liberalized copyright policy for current, future, and past coverage of any official events sponsored by Congress and any federal agency — about half of all programming offered on the C-SPAN television networks — which will allow non-commercial copying, sharing, and posting of C-SPAN video on the Internet, with attribution.' Here is the press release. The question remains whether videos of governmental proceedings should be public domain by default or whether the attribution requirement is reasonable in the face of easy video copying and distribution."

While participating in amateur rocket launches in Black Rock Desert (the site of Burning Man), Ian Kluft noticed rocks with some oddities. Through the Internet he learned the characteristics of impact craters, then found some clues in photographs and Google Maps. Examining the area, he collected samples of rock with impact patterns and other evidence. He found that previous geological puzzles in the region are well explained as impact structures. Volunteers are finding peculiarities in satellite imagery of the area. Kluft presents his evidence here — "Submitted for Study: Discovery of Possible Impact Crater at Nevada's Black Rock Desert." This is a preliminary, six-week effort intended to bring the site to the attention of geologists. Confirmation will take some time and more elaborate tools than his group has.

Butterspoon tips us to an article in Ars Technica titled "Everything you need to know about IPv6." Perhaps not quite "everything"; the article doesn't try to explain the reasons behind IPv6's meager adoption since its introduction 12 years ago. But it should be regarded as essential reading for anyone overly comfortable with their IPv4 addresses. Quoting: "As of January 1, 2007, 2.4 billion of those [IPv4 addresses] were in (some kind of) use. 1.3 billion were still available and about 170 million new addresses are given out each year. So at this rate, 7.5 years from now, we'll be clean out of IP addresses; faster if the number of addresses used per year goes up. Are you ready for IPv6?"
