News for nerds, stuff that matters
Google's Computing Power Refines Translationgollum123 sends an excerpt from the NY Times on how Google has taken a lead in language translation, in one of the company's few unqualified successes as it attempts to broaden is offerings beyond search. "...Google's quick rise to the top echelons of the translation business is a reminder of what can happen when Google unleashes its brute-force computing power on complex problems. The network of data centers that it built for Web searches may now be, when lashed together, the world's largest computer. Google is using that machine to push the limits on translation technology. Last month, for example, it said it was working to combine its translation tool with image analysis, allowing a person to, say, take a cellphone photo of a menu in German and get an instant English translation. ...in the mid-1990s, researchers began favoring a so-called statistical approach. They found that if they fed the computer thousands or millions of passages and their human-generated translations, it could learn to make accurate guesses about how to translate new texts. It turns out that this technique, which requires huge amounts of data and lots of computing horsepower, is right up Google's alley. ...Google's service is good enough to convey the essence of a news article, and it has become a quick source for translations for millions of people."

Cisco Introduces a 322 Tbit/sec. RouterCWmike writes "Today Cisco Systems introduced its next-generation Internet core router, the CRS-3, with about three times the capacity of its current platform. 'The Internet will scale faster than any of us anticipate,' Cisco's John Chambers said while announcing the product. At full scale, the CRS-3 has a capacity of 322Tbit/sec., roughly three times that of the CRS-1, introduced in 2004. It also has more than 12 times the capacity of its nearest competitor, Chambers said. The CRS-3 will help the Internet evolve from a messaging to an entertainment and media platform, with video emerging as the 'killer app,' Chambers said. Using a CRS-3, every person in China, which has a population just over 1.3 billion, could participate in a video phone call at the same time. (Or you could pump nearly one Library of Congress per second through the device, or give everyone in San Fransisco a 1Gbps internet connection.) AT&T said it has been using the CRS-3 to test 100Gbit/sec. data links in tests on a commercial fiber route in Florida and Louisiana."

Cybercrooks Surpassed Old School Bankrobbers In '09krebsonsecurity writes "Organized cyber-criminal gangs stole $25 million in the 3rd quarter alone last year, by pilfering the online bank accounts of small to midsized businesses, the FDIC reported last week. In contrast, traditional bank robbers hauled just $9.4 million in 1,184 bank robberies during that same period, according to an analysis of FBI bank crime statistics by krebsonsecurity.com. From that story: 'The federal government sure publishes a lot more information about physical bank robberies than it makes available about online stick-ups. Indeed, the FBI's bank crime stats are extraordinarily detailed. For example, they can tell you that in the 3rd quarter of last year, bank robbers were more likely to hold up their local branch between the hours of 9 a.m. and 11 a.m. on a Wednesday than at any other time or day of the week; they can tell you the number of tear gas and dye packs taken with the loot, the number of security cameras activated, the number of food stamps taken, even what percentage of suspected perpetrators had illegal drug habits at the time of the robberies. About the only thing the stats don't tell you is what brand of jeans the perpetrators were wearing and whether the getaway car had cool vanity plates. What do we get about e-crime statistics from the federal government? One guy from the FDIC giving a speech at the RSA conference."
