Next-Generation CAPTCHA Exploits the Semantic Gap 327

Posted by kdawson from the stand-and-identify dept.
captcha_fun writes "Researchers at Penn State have developed a patent-pending image-based CAPTCHA technology for next-generation computer authentication. A user is asked to pass two tests: (1) click the geometric center of an image within a composite image, and (2) annotate an image using a word selected from a list. These images shown to the users have fake colors, textures, and edges, based on a sequence of randomly-generated parameters. Computer vision and recognition algorithms, such as alipr, rely on original colors, textures, and shapes in order to interpret the semantic content of an image. Because of the endowed power of imagination, even without the correct color, texture, and shape information, humans can still pass the tests with ease. Until computers can 'imagine' what is missing from an image, robotic programs will be unable to pass these tests. The system is called IMAGINATION and you can try it out." This sounds promising given how broken current CAPTCHA technology is.

EMI Says Online File Storage Is Illegal 405

Posted by kdawson from the you-will-play-only-what-you-rent-from-us dept.
WiglyWorm writes "MP3tunes CEO Michael Robertson sent out an email to all users of the online music backup and place-shifting service MP3tunes.com, asking them to help publicize EMI's ridiculous and ignorant lawsuit against the company. EMI believes that consumers aren't allowed to store their music files online, and that MP3tunes is violating copyright law by providing a backup service."

Extreme Linux Server Available to North America 188

Posted by ScuttleMonkey from the hot-hardware dept.
jcasman writes "CNet is covering an announcement from Japanese Linux provider Plat'Home on a low-cost, super tough Linux-based server, now available in the US, that can handle extreme heat and cold. 'The OpenMicroServer is kind of an "extreme" use server pushing the boundaries for normal, low-cost hardware. In a 624-day endurance test, the OpenMicroServer performed normally under 122 degree F conditions. The unit also employs a power efficient AMD Alchemy (MIPS) CPU and precise part placement based on thermo-fluid analysis to achieve semi-hermetic construction.'"

Cyber Defense Competition Has A New Champion 66

Posted by ScuttleMonkey from the hack-the-gibson dept.
lisah writes "Several colleges across the country went head-to-head in San Antonio, Texas last weekend at the National Collegiate Cyber Defense Competition to see which team could best protect their networks against attacks. In a modern day version of Steal the Flag, the teams duked it out using identical network setups that included a Cisco router and five servers. In the end, Baker College took the champion's title from last year's winner, Texas A & M University."

Office 2007 Fails OOXML Test With 122,000 Errors 430

Posted by ScuttleMonkey from the money-greases-the-wheels dept.
I Don't Believe in Imaginary Property writes "Groklaw is reporting that some people have decided to compare the OOXML schema to actual Microsoft Office 2007 documents. It won't surprise you to know that Office 2007 failed miserably. If you go by the strict OOXML schema, you get a 17 MiB file containing approximately 122,000 errors, and 'somewhat less' with the transitional OOXML schema. Most of the problems reportedly relate to the serialization/deserialization code. How many other fast-tracked ISO standards have no conforming implementations?"

NASA Wants its MMO Created for Free 217

Posted by ScuttleMonkey from the get-what-you-pay-for dept.
fyc writes "It seems that the educational MMORPG NASA's proposing will no longer have a budget of $3 million. Instead, any prospective development partner is being asked to create and maintain the MMORPG for free under a 'non-reimbursable Space Act Agreement'. It won't be a one-sided agreement, though. From NASA's RFP: 'In exchange for a collaborator's investment to create and manage a NASA-based MMO game for fun and to enhance STEM [science, technology, engineering and mathematics], NASA will consider negotiating brand placement, limited exclusivity and other opportunities.'"

Patent Chief Decries Continued Downward Spiral of Patent Quality 179

Posted by ScuttleMonkey from the dudas-just-wants-his-rug-back dept.
Techdirt is reporting that Jon Dudas, head of the US Patent Office, is lamenting the continuing quality drop in patent submissions. Unfortunately, while this problem is finally getting the attention it deserves, the changes being implemented don't seem to be offering the correct solution. "When you set up a system that rewards people for not actually innovating in the market (but just speculating on paper), then of course, you're going to get more of that activity. When you set up a system that rewards those people to massive levels, well out of proportion with their contribution to any product, then of course you're going to get more of that activity. When you set up a system that gives people a full monopoly right that can be used to set up a toll booth on the natural path of innovation, then of course you're going to get more of that activity. When the cost of getting a patent is so much smaller than the potential payoff of suing others with it, then of course you're going to get more of that activity. The fact that Dudas is just noticing this now, while still pushing for changes that will make the problem worse, is a real problem. Patents were only supposed to be used in special cases. The fact that they've become the norm, rather than the exception, is a problem, and it doesn't seem like anyone is seriously looking into fixing that."

Ben Stein's 'Expelled' - Evolution, Academia and Conformity 1766

Posted by timothy from the ben-stein-is-smarter-than-you dept.
eldavojohn writes "Painting the current scientific community as just as bad as the Spanish Inquisition, an extended trailer of Ben Stein's "Expelled" has a lot of people (at least that I know) talking. It looks like his movie plans to encourage people to speak out if they believe intelligent design or creationism to be correct. In the trailer he even warns you that if you are a scientist you may lose your job by watching 'Expelled.' Backlash to the movie has started popping up and this may force the creationism/evolutionist debate to a whole new level across the big screen and the internet." adholden points out a site called Expelled Exposed, which asserts that 'Expelled' "is simply an anti-science propaganda film aimed at creating controversy where none exists, while promoting poor science education that can and will severely handicap American students."
