"The WSJ reports that widespread disruptions to Google in China over the weekend, halting use of everything from Google's search engine to its Gmail email service to its Google Play mobile-applications store, underscore the uncertainty surrounding Beijing's effort to control the flow of information into the country, as well as the risks that effort poses to the government's efforts to draw global businesses. The source of the disruptions couldn't be determined, but Internet experts pointed to China's Internet censorship efforts, which have been ratcheted up ahead of the 18th Party Congress. 'There appears to be a throttling under way of Web access,' says David Wolf, citing recent articles in foreign media about corruption and wealth in China spurred by the party congress and the fall of former party star Bo Xilai, 'that's their primary concern, people getting news either through Google or through its services.' Beijing risks a backlash if it were to block Google outright on a long-term basis, says Wolf and such a move could put Beijing in violation of its free-trade commitment under the World Trade Organization and make China a less-attractive place to do business. 'If China insists in the medium and long term of creating another Great Firewall between the China cloud and the rest of the world, China will be an increasingly untenable place to do business.'"

"Wired is reporting that the Stuxnet worm was apparently designed to subtly interfere with uranium enrichment by periodically speeding or slowing specific frequency converter drives spinning between 807Hz and 1210Hz. The goal was not to cause a major malfunction (which would be quickly noticed), but rather to degrade the quality of the enriched uranium to the point where much of it wouldn't be useful in atomic weapons. Statistics from 2009 show that the number of enriched centrifuges operational in Iran mysteriously declined from about 4,700 to about 3,900 at around the time the worm was spreading in Iran."

"When I was very young, my dad took me on a trip to his parents' farm. He wanted to show me 'The Crater.' We walked a long way through second generation hardwoods and finally stood on the rim of a hole that has no equal in this area. As I grew up, I became more interested in The Crater, and would always tell friends about it. It is roughly 1,200 feet across and 120 feet deep, and has a strange vibe about it. When you walk up to it, you feel like something really big happened here. Either the mother of all caves is down there, or a large object smashed into this place a long, long time ago. I bought aerial photos when I was twelve and later sent images from GIS to a geologist at a local university. He pretty much laughed me out of his office, saying that it was a sinkhole. He did wish me luck, however. It may be sinkhole. Who knows? Last week I borrowed a metal detector and went poking around, and have found the strangest shrapnel pieces I have ever seen. They are composed of a metal that reacts strongly to acids. The largest piece so far reacted with tap water and dish-washing detergent. My second trip today yielded lots of strange new pieces of metal, and hopefully, one day the truth will be known. Backyard science is so much fun. And who knows; if it is indeed a cave, maybe Cerberus resides there."

"A research and development group down under is working to develop an advanced video surveillance system for ports around the world that uses video superimposed onto a 3D map. With 16-megapixel high-definition cameras on a distributed (cabled) network and a proprietary system written in a variety of languages (C++, Python, SQL, etc.), the group from NICTA is aiming to allow security teams at the Port of Brisbane — which is 110km long — to monitor shipping movements, cargo and people. By scrolling along a 3D map, the security teams can click on a location and then get a real-time video feed superimposed onto the map. Authorities from around the world with the right permissions can then access the same system. The main difference from regular surveillance systems is the ability to switch views without having to know camera numbers/locations and the one screen view."
