Google Engineers Open Source Book Scanner Design

c0lo writes “Engineers from Google’s Books team have released the design plans for a comparatively reasonably priced (about $1500) book scanner on Google Code. Built using a scanner, a vacuum cleaner and various other components, the Linear Book Scanner was developed by engineers during the ’20 percent time’ that Google allocates for personal projects. The license is highly permissive, thus it’s possible the design and building costs can be improved. Any takers?” Adds reader leighklotz: “The Google Tech Talk Video starts with Jeff Breidenbach of the Google Books team, and moves on to Dany Qumsiyeh showing how simple his design is to build. Could it be that the Google Books team has had enough of destroying the library in order to save it? Or maybe the just want to up-stage the Internet Archive’s Scanning Robot. Disclaimer: I worked with Jeff when we were at Xerox (where he did this awesome hack), but this is more awesome because it saves books.” Read more of this story at Slashdot.

Australia's Biggest Telco Sold Routers With Hardcoded Passwords

mask.of.sanity writes “Hardcoded usernames and passwords have been discovered in a recent line of Telstra broadband routers that allow attackers access to customer networks. The flaws meant customer unique passwords could be bypassed to access the device administrative console and LAN.” Read more of this story at Slashdot.

Must-See Video: Real-Time English-to-Mandarin Speech Translation via Microsoft Research

As you might have noticed, we’ve had quite a bit of Asian design coverage lately (with a few more stories to come): between the second annual Beijing Design Week , a trip to Shanghai for Interior Lifestyle China and last week’s design events in Tokyo , we’re hoping to bring you the best of design from the Eastern Hemisphere this fall. Of course, I’ll be the first to admit that our coverage hasn’t been quite as quick as we’d like, largely due to the speed bump of the language barrier. At least two of your friendly Core77 Editors speak passable Mandarin, but when it comes to parsing large amounts of technical information, the process becomes significantly more labor-intensive than your average blogpost… which is precisely why I was interested to learn that Microsoft Research is on the case. In a recent talk in Tianjin, China, Chief Research Officer Rick Rashid (no relation to Karim) presented their latest breakthrough in speech recognition technology, a significant improvement from the 20–25% error of current software. Working with a team from the University of Toronto, Microsoft Research has “reduced the word error rate for speech by over 30% compared to previous methods. This means that rather than having one word in 4 or 5 incorrect, now the error rate is one word in 7 or 8.” An abridged transcript of the talk is available on the Microsoft Next blog if you want to follow along: In the late 1970s a group of researchers at Carnegie Mellon University made a significant breakthrough in speech recognition using a technique called hidden Markov modeling which allowed them to use training data from many speakers to build statistical speech models that were much more robust. As a result, over the last 30 years speech systems have gotten better and better. In the last 10 years the combination of better methods, faster computers and the ability to process dramatically more data has led to many practical uses. Just over two years ago, researchers at Microsoft Research and the University of Toronto made another breakthrough. By using a technique called Deep Neural Networks, which is patterned after human brain behavior, researchers were able to train more discriminative and better speech recognizers than previous methods. Once Rashid has gotten the audience up to speed, he starts discussing how current technology is implemented in extant translation services (5:03). “It happens in two steps,” he explains. “The first takes my words and finds the Chinese equivalents, and while non-trivial, this is the easy part. The second reorders the words to be appropriate for Chinese, an important step for correct translation between languages.” Short though it may be, the talk is a slow build of relatively dry subject matter until Rashid gets to the topic at hand at 6:45: “Now the last step that I want to take is to be able to speak to you in Chinese.” But listening to him talk for those first seven-and-a-half minutes is exactly the point : the software has extrapolated Rashid’s voice from an hour-long speech sample, and it modulates the translated audio based on his English speech patterns . Thus, I recommend watching (or at least listening) to the video from the beginning to get a sense for Rashid’s inflection and timbre… but here’s the payoff: (more…)

US Warships Could Soon Run on Detonated Waves

Every one of the modern US Navy’s 129 ships, and its entire fleet of aircraft, relies on gas turbines for either basic propulsion or to generate electricity for their critical systems—typically both. But as fuel costs continue to rise, these turbines now burn through nearly $2 billion of fuel annually. That’s why the Naval Research Lab is developing a revolutionary new type of engine that could reduce our armada’s energy consumption by as much as 25 percent (and save $400 million a year) even as the Navy transitions to “all electric” propulsion systems.

Solar Panel Breaks "Third of a Sun" Efficiency Barrier

Zothecula writes “Embattled photovoltaic solar power manufacturer Amonix announced on Tuesday that it has broken the solar module efficiency record, becoming the first manufacturer to convert more than a third of incoming light energy into electricity – a goal once branded ‘one third of a sun’ in a Department of Energy initiative. The Amonix module clocked an efficiency rating of 33.5 percent.” Read more of this story at Slashdot.

Increasing Wireless Network Speed By 1000% By Replacing Packets With Algebra

MrSeb writes “A team of researchers from MIT, Caltech, Harvard, and other universities in Europe, have devised a way of boosting the performance of wireless networks by up to 10 times — without increasing transmission power, adding more base stations, or using more wireless spectrum. The researchers’ creation, coded TCP, is a novel way of transmitting data so that lost packets don’t result in higher latency or re-sent data. With coded TCP, blocks of packets are clumped together and then transformed into algebraic equations (PDF) that describe the packets. If part of the message is lost, the receiver can solve the equation to derive the missing data. The process of solving the equations is simple and linear, meaning it doesn’t require much processing on behalf of the router/smartphone/laptop. In testing, the coded TCP resulted in some dramatic improvements. MIT found that campus WiFi (2% packet loss) jumped from 1Mbps to 16Mbps. On a fast-moving train (5% packet loss), the connection speed jumped from 0.5Mbps to 13.5Mbps. Moving forward, coded TCP is expected to have huge repercussions on the performance of LTE and WiFi networks — and the technology has already been commercially licensed to several hardware makers.” Read more of this story at Slashdot.
