hansamurai writes "After being asked about the App Store's recent ban on 'sexy apps,' Steve Jobs responded, 'We do believe we have a moral responsibility to keep porn off the iPhone. Folks who want porn can buy an Android phone. You know, there's a porn store for Android, you can download nothing but porn. You can download porn, your kids can download porn. That's a place we don't want to go, so we're not going to go there.' Apps such as Playboy's and the Sports Illustrated Swimsuit Edition are still available on the App Store, however, as they come from 'more reputable companies.'"

An anonymous reader writes "Two researchers say they have found a way to exploit weaknesses in the mobile telecom system to legally spy on people by figuring out the private cell phone number of anyone they want, tracking their whereabouts, and listening to their voice mail."

An anonymous reader writes "An interesting article yesterday about the unmasking of the recent creator of the controversial and iconic Obama/Joker image that has been popping up around Los Angeles with the word Socialism under it. The Los Angeles Times has identified the images' creator as Firas Alkhateeb. Even more interesting though is the fact that after getting over 20,000 hits on the image at Flickr, Flickr removed the image from Alkateeb's photostream, citing 'copyright' concerns. The image in question is clearly both an independent derivative work and unquestionably a parody of the President and Time Magazine which would be covered under fair use. It has appeared on many other sites without issue on the Internet." According to the same reader, "Flickr also recently nuked a user's entire photostream over negative comments on President Obama's official photostream."

Hugh Pickens writes "The NY Times reports that it is possible to fabricate blood and saliva samples containing DNA from a person other than the donor, and even to construct a sample of DNA to match someone's profile without obtaining any tissue from that person — if you have access to their DNA profile in a database. This undermines the credibility of what has been considered the gold standard of proof in criminal cases. 'You can just engineer a crime scene,' said Dan Frumkin, lead author of the paper. 'Any biology undergraduate could perform this.' The scientists fabricated DNA samples in two ways. One requires a real, if tiny, DNA sample, perhaps from a strand of hair or a drinking cup. They amplified the tiny sample into a large quantity of DNA using a standard technique called whole genome amplification. The other technique relies on DNA profiles, stored in law enforcement databases as a series of numbers and letters corresponding to variations at 13 spots in a person's genome. The scientists cloned tiny DNA snippets representing the common variants at each spot, creating a library of such snippets. To prepare a phony DNA sample matching any profile, they just mixed the proper snippets together. Tania Simoncelli, science adviser to the American Civil Liberties Union, says the findings were worrisome. 'DNA is a lot easier to plant at a crime scene than fingerprints,' says Simoncelli. 'We're creating a criminal justice system that is increasingly relying on this technology.'"

Al writes "NASA recently finished testing a miniature nuclear reactor that would provide power for an astronaut base on the Moon or Mars. The reactor combines a small fission system with a Stirling engine to make a 'safe, reliable, and efficient' way to produce electricity. The system being tested at NASA's Glenn Research Center can produce 2.3 kilowatts and could be ready for launch by 2020, NASA officials say. The reactor ought to provide much more power than solar panels but could prove controversial with the public concerned about launching a nuclear power source and placing it on the Moon or another planet."

Peace Corps Online writes "Concrete accounts for more than 5 percent of human-caused carbon dioxide emissions annually, mostly because cement, the active ingredient in concrete, is made by baking limestone and clay powders under intense heat that is generally produced by the burning of fossil fuels. Now Scientific American reports that British start-up company Novacem has developed a 'carbon-negative' cement that absorbs more carbon dioxide than it emits over its life cycle. The trick is to make cement from magnesium silicates rather than calcium carbonate, or limestone, since this material does not emit CO2 in manufacture and absorbs the greenhouse gas as it ages. 'The building and construction industry knows it has got to do radical things to reduce its carbon footprint and cement companies understand there is not a lot they can do without a technology breakthrough,' says Novacem Chairman Stuart Evans. Novacem estimates that for every ton of Portland cement replaced by its product, around three-quarters of a ton of CO2 is saved, turning the cement industry from a big emitter to a big absorber of carbon. Major cement makers have been working hard to reduce CO2 emissions by investing in modern kilns and using as little carbon-heavy fuel as possible, but reductions to date have been limited. Novacem has raised $1.7M to start a pilot plant that should be up and running in northern England in 2011."

The Slashdolt writes "After a stern criticism from Linus, the long-time kernel hacker Alan Cox has decided to walk away as the maintainer of the TTY subsystem of the Linux Kernel, stating '...I've had enough. If you think that problem is easy to fix you fix it. Have fun. I've zapped the tty merge queue so anyone with patches for the tty layer can send them to the new maintainer.'" A response to a subsequent post on the list makes it quite clear that he is serious.

Nguyen Van Chau, head of Ho Chi Minh City's Health Department, has revealed that many sick passengers who flew to Ho Chi Minh City used fever reducers to fool temperature scanners at the airport. The government has confirmed 26 people infected with H1N1 flu, 23 of whom came by air after traveling in the United States or Australia. State media reports that the discovery of these scanner cheaters led to the detection of several infected cases later.

Anonymous writes "Engineering students at Duke University have taken advantage of the accelerometers in emerging cell phones to create an application that permits users to write short notes in the air with their phone, and have that note automatically sent to an e-mail address. The 'PhonePoint Pen' can be held just like a pen, and words can be written on an imaginary whiteboard. With this application a user could take a picture with a phone camera, and annotating it immediately with a short caption. Duke Computer Engineering Professor Romit Roy Choudhury said that his research group is envisioning mobile phones as just not a communication device, but a much broader platform for social sensing and human-computer interaction. Such interactivity has also emerged in the work of other research groups, such as MIT's Sixth Sense project, Dartmouth's MetroSense project, and Microsoft Research's NeriCell project, to name a few."

Al writes "An engineer from Nokia's UK research labs says that the company is developing technology that can harvest ambient electromagnetic radiation to keep a cellphone going. The researcher says that his group is working towards a prototype that could harvest up to 50 milliwatts of power — enough to slowly recharge a phone that is switched off. He says current prototypes can harvest 3 to 5 milliwatts. It will require a wideband receiver capable of capturing signals from between 500 megahertz and 10 gigahertz — a range that encompasses many different radio communication signals. Other researchers have developed devices that can harvest more modest power from select frequencies. A team from Intel previously developed a compact sensor capable of drawing 6 microwatts from a 1.0-megawatt TV antenna 4.1 kilometers away."

An anonymous reader writes "The Chinese government has sponsored the development of a censorware package called 'Green Dam Youth Escort'; basically a PC-resident IP blocker that gets regular updates of banned sites from a central government site. There are now plans afoot to mandate that all new PCs sold in China be shipped with this software. The rationale behind this is to 'stop the poisoning of children's minds.'"

TheFrunj writes "Blizzard's games, such as World of Warcraft and StarCraft, are perhaps known for their breathtaking cinematics as much as for their gameplay. The process behind these cinematics is complex, involving an entire modeling and coding team — they even needed to make their own physics engine! AtomicMPC has the full story behind these incredible videos. Quoting: 'Storyboards become animated storyboards (thanks to a storyboard team who are also trained animators) complete with temporary music to help set the tone and get the pacing right. Then the animators and modeling team get involved, creating a rough 3D version of the final animation. While the modeling team works on characters and environments, the animators work with very low polygon characters and as the models are refined and updated the animations are refined. This is also where production technicians get involved, supporting the more technical developments like hair and skeletal systems for the characters. And then the effects team kicks into gear. '"
