oranghutan writes "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."

anthemaniac writes "Researchers for at least two decades have used acoustic levitation to suspend light materials without a container. Wenjun Xie, a materials physicist at Northwestern Polytechnical University in China, has previously used ultrasound fields to levitate globs of iridium and mercury, very heavy materials. Now the scientist has performed the feat with live animals. From the story: 'Xie and his colleagues employed an ultrasound emitter and reflector that generated a sound pressure field between them. The emitter produced roughly 20-millimeter-wavelength sounds, meaning it could in theory levitate objects half that wavelength or less.' Apparently the ants, spiders and ladybugs endured the trick just fine, but the fish didn't do so well due to lack of water."

netbuzz writes, "A fellow teaching himself Seam has come up with a clever Web app called 10 Minute Mail. It gives you a valid e-mail address — instantly — for use in registering at Web sites. Ten minutes later (more if you ask), it's gone. You can read mail and reply to it from the page where you create the throw-away address. Limited utility, yes, but easy and free."

An anonymous reader writes, "Cryptographer David Chaum and his research team have invented a new voting protocol which allows voters to verify that their vote has been correctly cast and counted. This is enabled using a surprisingly low-tech technique of cryptographic secret sharing. The secret — your marked ballot — is split into two halves using a hole punch" You take half home and can verify later via a Web interface how your particular ballot was counted.

We are essentially creating a user-submitted repository of the 'source' speech audio for the creation of Acoustic Models to be used by Speech Recognition Engines. The Speech Audio files will then be 'compiled' into Acoustic Models for use with Open Source Speech Recognition engines such as Sphinx, HTK, CAVS and Julius." Read on for why we need free GPL speech audio.

Krishna Dagli writes to mention an article at the Guardian site about an increasing interest in the possibility of identifying users by their 'clickprint', or online access habits. The article discusses a new paper on online identification written by two American professors. The piece posits that not only is nailing down individual users by their habits useful for advertisers looking to sell products, it may be possible to use this information to flag stolen identities. From the article: "'Our main finding is that even trivial features in an internet session can distinguish users,' Padmanabhan told the Wharton Review. 'People do seem to have individual browsing behaviors.' The duo found that anywhere from three to 16 sessions are needed to identify an individual's clickprint ... In one example, they found that from just seven aggregated sessions they could distinguish between two different surfers with a confidence of 86.7%. Given 51 sessions, the confidence level rose to 99.4%."

Da Massive writes, "Debian GNU/Linux is experimenting with a new project called Dunc-Tank, which is aimed at securing funding to pay two key release managers — Steve Langasek and Andi Barth — in an effort to ensure the forthcoming Debian 4.0, known as etch, is released on time in December." Dunc-Tank is not affiliated with the Debian Project directly, and in fact was controversial on the debian-private list.

ludwigvan968 writes "The University of Texas New Media Initiative in association with Google's Summer of Code program have been working on a project to make sharing files over the internet easier than ever before. Summer of Code intern Evan Wilson just released Project Snakebite, the first fully automatic BitTorrent server. Just as with a normal webserver, you drop files in a folder to share them. Snakebite takes care of generating torrent files and running a tracker and a seeder for each file. Additionally, it builds a user-customizable link page with all of your files. It will even register your Snakebite server with an easy to remember URL for people that can't remember their IP. Snakebite is free and open software and is currently released for Debian. It's fully portable to both Windows and OS X and the developers just need some help packaging it."

An anonymous reader writes "A recent study on spam has revealed that spammers see a return between 4.9% and 6% when selling stocks they have bought low and spammed the world with." From the article: "The researchers say that approximately 730 million spam e-mails are sent every week, 15% of which tout stocks. Other estimates of spam volumes are far higher. The study, by Professor Laura Frieder of Purdue University in the US and Professor Jonathan Zittrain from Oxford University's Internet Institute in the UK, analysed more than 75,000 unsolicited e-mails. All of the messages touting stocks and shares were sent between January 2004 and July 2005."

Lucy V. asks: "My husband works for a firm in New York that receives customer data on CD and DVD. After copying the data to their server, they are required to retain the original media for several months until the job is delivered and the customer has approved the work. It is common for the firm to have 30,000 CD's and DVD's on hand at any one time. They are struggling to find a better storage solution than what they have now as the current setup is awkward and requires quite a bit of space. They are removing the media from the jewel case and slipping them into one of those large notebook style disk holders and then storing the notebook on a shelf. I have spent quite a bit of time doing web searches for CD and DVD storage but nearly all the racks that I find are low capacity ones intended for home use. I have found one vendor called Can-Am that makes a high quality steel drawer system that might fit the bill." Has anyone found (or put together) a storage system that can handle thousands of discs?

Davemania writes "New York Times reports that the Evolution biology subject has disappeared from a list of acceptable fields of study for recipients of a federal education grant for low-income college students. The Education department has described this as a Clerical Mistake but others are skeptical about this. 'Scientists who knew about the omission also said they found the clerical explanation unconvincing, given the furor over challenges by the religious right to the teaching of evolution in public schools. "It's just awfully coincidental," said Steven W. Rissing, an evolutionary biologist at Ohio State University.'" As someone who made use of one of those grants to study Evolutionary Biology, I find this more than a little galling.

olclops writes "It's a big day for astrophysics. After much speculation, scientists now have conclusive proof of dark matter. This result doesn't rule out alternate gravity theories like MOND, but it does mean those theories will have to account for exotic forms of dark matter."
