How Close Are We To Engineering the Climate? 319

merbs writes The scientists had whipped themselves into a frenzy. Gathered in a stuffy conference room in the bowels of a hotel in Berlin, scores of respected climate researchers were arguing about a one-page document that had tentatively been christened the "Berlin Declaration." It proposed ground rules for conducting experiments to explore how we might artificially cool the Earth—planet hacking, basically. This is the story of scientists' first major international meeting to tackle geoengineering. It’s most commonly called geoengineering. Think Bond-villain-caliber schemes but with better intentions. It’s a highly controversial field that studies ideas like launching high-flying jets to dust the skies with sulfur in order to block out a small fraction of the solar rays entering the atmosphere, or sending a fleet of drones across the ocean to spray seawater into clouds to make them brighter and thus reflect more sunlight. Those are two of the most discussed proposals for using technology to chill the planet and combat climate change, and each would ostensibly cost a few billion dollars a year—peanuts in the scheme of the global economy. We’re about to see the dawn of the first real-world experiments designed to test ideas like these, but first, the scientists wanted to agree on a code of ethics—how to move forward without alarming the public or breaking any laws.

Automation May Make Toll Roads More Common 585

bfwebster writes "Here in Denver, we have E-470, a toll section of the 470 beltway, that uses the usual transponder attached to your windshield. Fair enough, and I make use of it, particularly in driving to the airport. But they've just implemented new technology on E-470 that allows anyone to drive through the automated toll gates. If you don't have a transponder, it takes a photo of your license plate and sends a monthly bill to your house. As a result, the company that runs E-470 plans to close all human-staffed toll booths by mid-summer. And as an article in this morning's Rocky Mountain News notes, 'Such a system could be deployed on other roads, including some that motorists now use free. The result: a new source of money for highways and bridges badly in need of repair.' You can bet that legislators, mayors, and city councilpersons everywhere will see this as an even-better source of income than red-light cameras. You've been warned."

New Report On NSA Released Today 81

daveschroeder writes "George Washington University has today released a three-volume history of NSA activities during the Cold War (major highlights). Written by agency historian Thomas R. Johnson, the 1,000-page report, 'Cryptology During the Cold War, 1945-1989,' details some of the agency's successes and failures, its conflict with other intelligence agencies, and the questionable legal ground on which early American cryptologists worked. The report remained classified for years, until Johnson mentioned it to Matthew Aid, an intelligence historian, at an intelligence conference. Two years later, an abstract and the three current volumes of the report are now available (PDF) from GWU and the National Security Archive. Aid, author of the forthcoming history 'The Secret Sentry: The Top Secret History of the National Security Agency,' says Johnson's study shows 'refreshing openness and honesty, acknowledging both the NSA's impressive successes and abject failures during the Cold War.' A fourth volume remains classified. Johnson says in an audio interview: 'If you are performing an operation that violates a statute like FISA, it's going to come out. It always comes out.'" And reader sampas zooms in on a section in Document 6 about the growth of NSA's IT: their first Cray purchase in 1976, the growth of circuits between facilities, and internal feuds over centralized IT development vs. programmers-in-departments. "A young systems engineer named [redacted] was urging NSA to look at some technology that had been developed by the Defense Advanced Research Projects Agency (DARPA). In 1969 DARPA had developed a computer internetting system called ARPANET... NSA quickly adopted the DARPA solution. The project was called platform."

OpenOffice.org 3.0 Is Officially Here 284

SNate writes "After a grinding three-year development cycle, the OpenOffice.org team has finally squeezed out a new release. New features include support for the controversial Microsoft OOXML file format, multi-page views in Writer, and PDF import via an extension. Linux Format has an overview of the new release, asking the question: is it really worth the 3.0 label?"

Homeland Security's Space-Based Spying Goes Live 289

BountyX writes "While America's attention has shifted to the economic meltdown and the presidential race between corporate favorites John McCain and Barack Obama, The Wall Street Journal reported Wednesday that the Department of Homeland Security's (DHS) National Applications Office (NAO) 'will proceed with the first phase of a controversial satellite-surveillance program, even though an independent review found the department hasn't yet ensured the program will comply with privacy laws.' NAO will coordinate how domestic law enforcement and 'disaster relief' agencies such as FEMA use satellite imagery intelligence (IMINT) generated by US spy satellites. Based on available evidence, hard to come by since these programs are classified 'above top secret,' the technological power of these military assets are truly terrifying."

Google News Removes Belgian Newspaper 381

CaVi writes "Following a judicial action (link in French) by the 'French-speaking Belgian Association of the press,' Google.be has removed all the French-speaking press sites from its index, as can be seen by doing a search. The court order to Google is posted at Chilling Effects. In summary, the editors want a cut of the profit that Google News makes using their information. No such deal exists for the moment. Google has been ordered to remove all references, or pay one million Euros per day if it doesn't comply. Net effect: they removed all link to the sites, from Google News, but also from Google's search. Will Google become irrelevant in Belgian, and be replaced by MSN? Or will the newspapers, which gain from commercials, and thus net traffic, change their position when they'll see the drop in traffic that it is causing?" There's also a link to a Dutch news article on the subject; one of the key issues was evidently that some of what Google was carrying was no longer available on the newspaper's website itself, so rather then linking to the newspaper, Google was displaying it on their own.
