An anonymous reader writes "Viewable with Tor installed, search engine DuckDuckGo has erected a hidden service for secure, encrypted searches through the Tor network. While past attempts at hidden service search engines failed due to uptime or quality issues, DuckDuckGo marks the first time a real company operating a public search engine has offered a solid search engine as a hidden service for Tor users."

Ignorant Aardvark writes "Xiph.org just released the first installment in its video series 'A Digital Video Primer For Geeks,' which covers digital audio and video fundamentals. The first video covers basic concepts of how digital audio and video are encoded, and does so in an understandable fashion. The video is hosted by Monty, the founder of Xiph.org (the people who brought you Ogg), and explains a lot of concepts (FourCC codes, YUV color space, gamma, etc.) that many watchers of digital video have long been exposed to, but don't quite understand themselves. The intent of the video series (in addition to general education) is to spur interest in digital encoding and get more free software hackers involved in digital audio/video."

DrgnDancer sends in an NPR piece on recent efforts to control so-called "information weapons" on the Internet. What's interesting is that the term "information weapon," as defined by many of the countries trying to limit them, doesn't mean what you would think. It's closer to the old Soviet term "ideological aggression." "At a UN disarmament conference in 2008, Sergei Korotkov of the Russian Defense Ministry argued that anytime a government promotes ideas on the Internet with the goal of subverting another country's government — even in the name of democratic reform — it should qualify as 'aggression.' And that, in turn, would make it illegal under the UN Charter. 'Practically any information operation conducted by a state or a number of states against another state would be qualified as an interference into internal affairs,' Korotkov said through an interpreter. 'So any good cause, like [the] promotion of democracy, cannot be used as a justification for such actions.' The Russians, and a lot of other countries such as Iran and China, apparently consider the free exchange of information to be an information technology threat. One that must be managed by treaty."

Bruce Perens writes "Codec2 is an Open Source digital voice codec for low-bandwidth applications, in its first Alpha release. Currently it can encode 3.75 seconds of clear speech in 1050 bytes, and there are opportunities to code in additional compression that will further reduce its bandwidth. The main developer is David Rowe, who also worked on Speex. Originally designed for Amateur Radio, both via sound-card software modems on HF radio and as an alternative to the proprietary voice codec presently used in D-STAR, the codec is probably also useful for telephony at a fraction of current bandwidths. The algorithm is based on papers from the 1980s, and is intended to be unencumbered by valid unexpired patent claims. The license is LGPL2. The project is seeking developers for testing in applications, algorithmic improvement, conversion to fixed-point, and coding to be more suitable for embedded systems."

eldavojohn writes "Google, already the largest search engine in the United States, went instant a few weeks ago. MIT's Tech Review asks why Google went instant and is skeptical that users actually look at search results before they finish typing their query. Othar Hansson, Google's lead on the initiative, informs them otherwise and claims that Google's traffic monitors didn't even blink at the extra data being sent across — primarily because of its insignificance next to streaming one video on YouTube. Hansson also reveals that Google's search engine is no longer stateless and therefore takes up a little more memory in their server hives. The Tech Review claims that 'sources at the company say Google Instant's impact on ad sales was a primary focus in testing the service. Google only gets paid for an advertisement, or sponsored link, when a user clicks on the ad, and ads are targeted to specific searches. By displaying a search's ads onscreen a couple of seconds sooner, the frequency of users clicking on those ads could only go up.' So money seemed to be the prime motivator and the article also coyly notes that the average length of time a user spends between typing in any two characters is 300 milliseconds — much too fast for old JavaScript engines. Of course, you might recall Google's efforts to change all that with JavaScript speed wars. Do you find Google Instant to be useful in any way, or does it strike you as just more ad gravity for your mouse?"

An anonymous reader writes "Running 64-bit Linux? Haven't updated yet? You're probably being rooted as I type this. CVE-2010-3081, this week's second high-profile local root exploit in the Linux kernel, is compromising machines left and right. Almost all 64-bit machines are affected, and 'Ac1db1tch3z' (classy) published code to let any local user get a root shell. Ac1db1tch3z's exploit is more malicious than usual because it leaves a backdoor behind for itself to exploit later even if the hole is patched. Luckily, there's a tool you can run to see if you've already been exploited, courtesy of security company Ksplice, which beat most of the Linux vendors with a 'rebootless' version of the patch."

theodp writes "This week's NY Times Magazine — a special issue on education and technology — is tailor-made for the Slashdot crowd. For the cover story, Sarah Corbett explores the games-and-education movement, which she notes is alive and well at Quest to Learn, a NYC middle-school that aims to make school nothing less than 'a big, delicious video game.' Elsewhere in the issue, Paul Boutin writes about Microsoft's efforts to inspire The 8-Year-Old Programmer with its Kodu Project, and Nicholas Carlson reports on Columbia University's efforts to mix journalism and hard-core computer science with its unique dual-degree master's in journalism and CS. There's also an accompanying timeline that nicely illustrates how learning machines have progressed from the Horn-Book to the iPad."

Trailrunner7 writes "A pair of security researchers have implemented an attack that exploits the way that ASP.NET Web applications handle encrypted session cookies, a weakness that could enable an attacker to hijack users' online banking sessions and cause other severe problems in vulnerable applications. Experts say that the bug, which will be discussed in detail at the Ekoparty conference in Argentina this week, affects millions of Web applications."

destinyland writes "An online music site has raised over $13,000 to hire a full orchestra to record royalty-free classical music. ('"Although the actual symphonies are long out of copyright, there is separate protection for every individual performance by an orchestra," notes one technology site.') MusOpen has reached their fundraising goal for both the orchestra and a recording facility, and will now record the complete symphonies of Beethoven, Brahms, Sibelius and Tchaikovsky. And because their fundraising deadline doesn't end until Tuesday, they've promised to add additional recordings for every additional $1,000 raised."

An anonymous reader writes "With its new Caffeine search indexing system, Google has moved away from its MapReduce distributed number crunching platform in favor of a setup that mirrors database programming. The index is stored in Google's BigTable distributed database, and Caffeine allows for incremental changes to the database itself. The system also uses an update to the Google File System codenamed 'Colossus.'"

An anonymous reader wrote to tell us a federal appeals court ruled today that the first sale doctrine is "unavailable to those who are only licensed to use their copies of copyrighted works." This reverses a 2008 decision from the Autodesk case, in which a man was selling used copies of AutoCAD that were not currently installed on any computers. Autodesk objected to the sales because their license agreement did not permit the transfer of ownership. Today's ruling (PDF) upholds Autodesk's claims: "We hold today that a software user is a licensee rather than an owner of a copy where the copyright owner (1) specifies that the user is granted a license; (2) significantly restricts the user’s ability to transfer the software; and (3) imposes notable use restrictions. Applying our holding to Autodesk’s [software license agreement], we conclude that CTA was a licensee rather than an owner of copies of Release 14 and thus was not entitled to invoke the first sale doctrine or the essential step defense. "

An anonymous reader writes "European Parliament today adopted Written Declaration 12/2010 which basically tells the Commission to all but drop the negotiations. From the article: 'Citizens from all around Europe helped to raise awareness about ACTA among Members of the European Parliament (MEPs) by collecting, one by one, more than 369 [of the MEPs'] signatures. With Written Declaration 12/20103, the European Parliament as a whole takes a firm position to oppose the un-democratic process of the Anti-Counterfeiting Trade Agreement (ACTA), and its content harmful to fundamental freedoms and the Internet ecosystem.'"

cortex writes with an excerpt from the L.A. Times: "In a first step toward helping severely paralyzed people communicate more easily, Utah researchers have shown that it is possible to translate recorded brain waves into words, using a grid of electrodes placed directly on the brain. ... The device could benefit people who have been paralyzed by stroke, Lou Gehrig's disease or trauma and are 'locked in' — aware but unable to communicate except, perhaps, by blinking an eyelid or arduously moving a cursor to pick out letters or words from a list. ... Some researchers have been attempting to 'read' speech centers in the brain using electrodes placed on the scalp. But such electrodes 'are so far away from the electrical activity that it gets blurred out,' [University of Utah bioengineer Bradley] Greger said. ... He and his colleagues instead use arrays of tiny microelectrodes that are placed in contact with the brain, but not implanted. In the current study, they used two arrays, each with 16 microelectrodes."

I'm Not There (1956) writes "Sociologist Clifford Nass is talking about how people think of their computers as something like human beings. In one of his experiments, Nass found that people are more willing to 'help' computers when the computer helped them previously: 'When people were then asked to help optimize the screen resolution on a computer where the program had been "helpful," they were much more likely to do so than with the less helpful version.' He also found that people evaluating software's performance were more forgiving if the evaluation was done on the same computer the software was tested on. Nass has recently published the book The Man Who Lied to His Laptop, in which he 'uses our interactions with machines to investigate how human relationships could be improved.'"

eldavojohn writes "For decades, Stanford has been working on a different kind of Wikipedia. It might even be considered closer to a peer-reviewed journal, since you have get submissions past a 120 person group of leading philosophers around the world, not to mention Stanford's administration. It has several layers of approval, but the authoritative model produces high quality content — even if it only amounts to 1,200 articles. Content you can read straight through to find everything pertinent — not hop around following link after link like the regular Wikipedia. You might question the need for this, but one of the originators says, 'Our model is authoritative. [Wikipedia's] model is one an academic isn't going to be attracted to. If you are a young academic, who might spend six months preparing a great article on Thomas Aquinas, you're not going to publish in a place where anyone can come along and change this.' The site has articles covering topics from Quantum Computing to technical luminaries like Kurt Friedrich Gödel and Alan Turing. The principal editor said, 'It's the natural thing to do. I'm surprised no one is doing it for the other disciplines.'"
