An anonymous reader writes "Dissipation of contrails with a powerful microwave beam aligned behind aircraft engines is being touted as a possible solution to help address air transport's effects on the climate. 'The remote heating of condensation nuclei could be achieved by applying electromagnetic radiation, such as microwaves,' says Cranfield University's Frank Noppel. 'Depending on assumptions made, calculation shows that the power required for such a device could be as little as 0.1% of the engine power.'"

Vigile writes "Today during a press briefing at AMD's offices in Austin, TX the company showed off some upcoming technology that should be available sometime early in 2009. What was most impressive was the overclocked speeds of the pending Phenom II X4 45nm processors. On air cooling AMD showed the quad-core CPU running at nearly 4.0 GHz while with much more extreme liquid nitrogen cooling help the same CPU reached over 6.0 GHz! It looks like AMD's newest processor might finally once again compete with the best from Intel, including its recent Core i7 CPUs."

roncosmos writes "Science News has up a feature on the first use of sound recording in a presidential campaign. In 1908, for the first time, presidential candidates recorded their voices on wax cylinders. Their voices could be brought into the home for 35 cents, equivalent to about $8 now. In that pre-radio era, this was the only way, short of hearing a speech at a whistle stop, that you could hear the candidates. The story includes audio recordings from the 1908 candidates, William Jennings Bryan and William Howard Taft. Bryan's speech, on bank failures, seems sadly prescient now. Taft's, on the progress of the Negro, sounds condescending to modern ears but was progressive at the time. There are great images from the campaign; lots of fun."

jammag writes "Open source advocate Bruce Perens writes in Datamation about a major court victory for open source: 'An appeals court has erased most of the doubt around Open Source licensing, permanently, in a decision that was extremely favorable toward projects like GNU, Creative Commons, Wikipedia, and Linux.' The case, Jacobsen v. Katzer, revolved around free software coded by Bob Jacobsen that Katzer used in a proprietary application and then patented. When Katzer started sending invoices to Jacobsen (for what was essentially Jacobsen's own work), Jacobsen took the case to court and scored a victory that — for the first time — lays down a legal foundation for the protection of open source developers. The case hasn't generated as many headlines as it should."

Tsunayoshi writes "My son volunteered me to give a presentation on what I do for a living for career day at his elementary school. I need to come up with a roughly 20-minute presentation to be given to 4-5 different classrooms. I am a systems administrator, primarily Unix/Linux and enterprise NAS/SAN storage, working for an aerospace company. I was thinking something along the lines of explaining how some everyday things they experience (websites, telephone systems, etc.) all depend on servers, and those servers are maintained by systems administrators. I was also going to talk about what I do specifically, which is maintain the computer systems that allow the really smart rocket scientists to get things into space. Am I on the right track? Can anyone suggest some good (and cheap/easy to make) visual aids?"

asoduk writes to tell us that a new world record has been set for the most efficient photovoltaic device. Topping the scale at 40.8% efficiency, the new solar cell differs significantly from the previous record holder. "Instead of using a germanium wafer as the bottom junction of the device, the new design uses compositions of gallium indium phosphide and gallium indium arsenide to split the solar spectrum into three equal parts that are absorbed by each of the cell's three junctions for higher potential efficiencies. This is accomplished by growing the solar cell on a gallium arsenide wafer, flipping it over, then removing the wafer. The resulting device is extremely thin and light and represents a new class of solar cells with advantages in performance, design, operation and cost."

This past weekend, Trixter — a self-proclaimed IBM PC historian — picked up some old software for his archive. What he didn't count on was a couple of additional Avantage titles that had never been released into the wild. If this weren't enough of a find, one of these titles provided Trixter with an interesting puzzle: the diskette for Mental Blocks is apparently hand-formatted to work on both C64 and IBM (on a single side, not the "flippy disks" of old). Quite an interesting little piece of history.

Smivs writes "The BBC reports that Earth's most ancient rocks, with an age of 4.28 billion years, have been found on the shore of Hudson Bay, Canada. Writing in Science journal, a team reports finding that a sample of Nuvvuagittuq greenstone is 250 million years older than any rocks known. It may even hold evidence of activity by ancient life forms. If so, it would be the earliest evidence of life on Earth — but co-author Don Francis cautioned that this had not been established. 'The rocks contain a very special chemical signature — one that can only be found in rocks which are very, very old,' he said."

ashitaka writes "KDDI has announced that they will be launching a 1Gbps Internet service to single-family home and condo users in October. The service is supposedly synchronous, with 1Gbps in both directions, although the article implies that speeds will vary with location. Cost will be 5,985 yen/month (about US$56.50) for the basic Internet and IP phone service. This is intended to compete with NTT, who currently control over 70% of the Japanese FTTH market."

An anonymous reader writes "So, you thought you did well to support the fledgling music industry by purchasing your tracks legally from the Wal-Mart store? Well, forget about moving these tracks to a new PC! Since they started selling DRM-free tracks last year, there's no money to be made in maintaining the DRM support systems, and in fact, support is being shut down. Make sure you circumvent the restrictions by burning the tracks to an old-fashioned CD before Wal-mart 'will no longer be able to assist with digital rights management issues for protected WMA files purchased from Walmart.com.' Support ends October 9th."

Anti-Globalism writes with this excerpt from CNet: "Google's vision of tomorrow's wireless network is in stark contrast to how wireless operators do business today, setting the two sides on a possible collision course. Earlier this week, the search giant filed a patent application with the US Patent Office describing its vision of an open wireless network where smartphones aren't tied to any single cell phone network. In Google's open wireless world, phones and other wireless devices would search for the strongest, fastest connection at the most competitive price. Essentially, wireless operators' networks would be reduced to 'dumb pipes.'" The full patent application is available as well. Google founder Larry Page recently asked the FCC to free up portions of the broadcast spectrum for this purpose.

Lucas123 writes "California's Secretary of State, Debra Bowen, was among a group of e-voting experts at MIT yesterday who said the nation's electronic voting systems are still not secure and many run on faulty software. Among the suggestions offered to fix the problem: use open source software, stop delivering e-voting machines to polling places weeks in advance of an election, and keep a paper trail for auditing purposes. Bowen also believes that a ubiquitous Internet voting system could not work without the use of a national ID card system."

I Don't Believe in Imaginary Property writes "The Senate has passed the PRO-IP Act. While they stripped out the provision to have the DoJ act as copyright cops, it still contains increased penalties for infringement, civil forfeiture provisions, and creates an 'IP czar' to coordinate enforcement. Even though the civil forfeiture provisions are ostensibly intended for use against commercial piracy outfits, history indicates that they will probably get used against individuals at some point. Worse, because they left out the only part of the bill that Bush threatened to veto, it is expected to pass. It is going back to the House where they're expected to pass it on Saturday, after which the President will probably sign it. So, if you want to contact your representative, hurry." An anonymous reader notes that DefectiveByDesign.Org is mobilizing to fight this legislation. The Senate vote was unanimous. We've been following the progress of this bill for quite some time.

Gamasutra did an in-depth interview with Yoshi Ono, producer of Street Fighter IV, about trying to bring the series back to the quality and popularity of the '90s. Ono also talks about broadening the market to include casual players, who were slowly driven away from the game by the increased focus on competitive play. Quoting: "If you think about chess for instance, a kid and a grandfather can play the same game, with the same ruleset, and understand what's going on. I think through our competitive spirit back then; we were always out to out-complicate each other, and make our systems deeper and deeper. It was ok then because there was a wide player base who understood how to play these games, but that's not true anymore. What we're trying to do with Street Fighter IV is bring them back in. There's not a whole lot of other fighting games out there to compare it to, but hopefully, if we play our cards right and get people back in to the genre, we can blossom the genre itself again and spread things out and get it back to the way it was."
