Fifth of Android Apps Expose Private Data 286

Posted by CmdrTaco from the that's-why-i-only-use-lynx dept.
WrongSizeGlass writes "CNET is reporting that a fifth of Android apps expose private data. The Android market threat report details the security issues uncovered. Dozens of apps were found to have the same type of access to sensitive information as known spyware does, including access to the content of e-mail and text messages, phone call information, and device location. 5% of the apps were found to have the ability to make calls, and 2% can send text messages, without the mobile user doing anything."

DIY Synthetic Aperture Radar 118

Posted by kdawson from the be-the-first-on-your-block dept.
An anonymous reader lets us know about a DIY synthetic aperture radar built for $240 in parts (give or take). Here's PDF slideware from the Ph.D. student's research. "Using a discarded garage door opener, an old cordless drill, and a collection of surplus microwave parts, a high resolution X-band linear rail synthetic aperture radar (SAR) imaging system was developed for approximately $240 material cost. Entry into the field of radar cross section measurements or SAR algorithm development is often difficult due to the cost of high-end precision pulsed IF or other precision radar test instruments."

Quantum Dots Could Double Solar Energy Efficiency 112

Posted by kdawson from the hot-enough-for-ya dept.
dptalia notes the recent publication in Science of research demonstrating a way to use hot electrons in solar cells, resulting in an overall energy conversion efficiency of 66%. Here is the abstract in Science; access to the full article requires a subscription. "A team of University of Minnesota-led researchers has cleared a major hurdle in the drive to build solar cells with potential efficiencies up to twice as high as current levels, which rarely exceed 30 percent. ... Tisdale and his colleagues demonstrated that quantum dots — made not of silicon but of another semiconductor called lead selenide — could indeed be made to surrender their 'hot' electrons before they cooled. The electrons were pulled away by titanium dioxide, another common inexpensive and abundant semiconductor material that behaves like a wire."

Ranking Soccer Players By Following the Bouncing Ball 142

Posted by timothy from the well-it-ain't-baseball dept.
sciencehabit excerpts from an interesting report on statistics for soccer, in the stats-obsessed world of sports: "Only a handful of soccer ranking systems exist, most of which rely on limited information: the number of goals scored in a match, the number of goals assisted, and some indices of a match's difficulty and importance. ... So researchers turned to an unlikely source: social networks. Applying the kinds of mathematical techniques used to map Facebook friends and other networks, the team created software that can trace the ball's flow from player to player. As the program follows the ball, it assigns points for precise passing and for passes that ultimately lead to a shot at the goal. Whether the shot succeeds doesn't matter. Only the ball's flow toward the goal and each player's role in getting it there factors into the program's point system, which then calculates a skill index for each team and player."

Apple's "iKey" Wants To Unlock All Doors 383

Posted by kdawson from the get-yours-at-ikea dept.
Pickens writes "The Telegraph reports that Apple is developing technology, already being nicknamed the 'iKey,' which will allow users to gain access to their office and unlock their car or front door with a single electronic device like an iPhone. Users would simply have to enter a PIN and wave the device over an electronic pad fitted beside a door to open it. 'The device can communicate with an external device to open a lock. By way of example, the electronic device may be a model of an iPhone,' says the newly released patent application. 'The external device may be any suitable electronic device such as a portable media player, personal data assistant or electronic lock that may be used to access a door, car, house, or other physical area.' The technology behind the invention is known as Near Field Communication; it allows electronic devices to transmit information when in proximity. 'If true, it's a very big deal. As well as opening doors and unlocking your car, it could also turn your iPhone into an electronic wallet and ID card,' says Leander Kahney, a consumer technology expert. 'The trouble is that the technology hasn't gone completely mainstream. If Apple were to adopt the technology, they would likely set the standard, and that would drive widespread adoption as everyone scrambles to make their systems iPhone-friendly.'"

ailnlv writes "Days on Earth just got shorter. The recent earthquake in Chile shifted the planet's axis by about 8 cm and shortened days by 1.26 microseconds 'The changes can be modeled, though they're difficult to detect physically given their small size. ...

Aurora Attack — Resistance Is Futile, Pretty Much 268

Posted by kdawson from the big-leagues dept.
eldavojohn writes "Do you have branch offices in China? iSec has published a new report (PDF) outlining the severity of the attacks on Google.cn, allegedly by the Chinese government, dubbed 'Aurora' attacks. Up to 100 companies were victims, and some are speculating that resistance to such attacks is futile. The report lays out the shape of the attacks — which were customized per-company based on installed vulnerable software and antivirus protection: '1. The attacker socially engineers a victim, often in an overseas office, to visit a malicious website. 2. This website uses a browser vulnerability to load custom malware on the initial victim's machine. 3. The malware calls out to a control server, likely identified by a dynamic DNS address. 4. The attacker escalates his privilege on the corporate Windows network, using cached or local administrator credentials. 5. The attacker attempts to access an Active Directory server to obtain the password database, which can be cracked onsite or offsite. 6. The attacker uses cracked credentials to obtain VPN access, or creates a fake user in the VPN access server. 7. At this point, the attack varies based upon the victim. The attacker may steal administrator credentials to access production systems, obtain source code from a source repository, access data hosted at the victim, or explore Intranet sites for valuable intellectual property.' The report also has pages of recommendations as well as lessons learned, which any systems administrator — even those inside the US — should read and take note of."

Newborns' Blood Used To Build Secret DNA Database 263

Posted by kdawson from the texas-baby-blood-spots dept.
Kanel notes a summary up at New Scientist of an investigation by a Texas newspaper revealing that Texas health officials had secretly transferred hundreds of newborn babies' blood samples to the federal government to build a DNA database. Here's the (long and detailed) article in the Texas Tribune. From New Scientist: "The Texas Department of State Health Services routinely collected blood samples from newborns to screen for a variety of health conditions, before throwing the samples out. But beginning in 2002, the DSHS contracted Texas A&M University to store blood samples for potential use in medical research. These accumulated at rate of 800,000 per year. The DSHS did not obtain permission from parents, who sued the DSHS, which settled in November 2009. Now the Tribune reveals that wasn't the end of the matter. As it turns out, between 2003 and 2007, the DSHS also gave 800 anonymized blood samples to the Armed Forces DNA Identification Laboratory to help create a national mitochondrial DNA database. This came to light after repeated open records requests filed by the Tribune turned up documents detailing the mtDNA program. Apparently, these samples were part of a larger program to build a national, perhaps international, DNA database that could be used to track down missing persons and solve cold cases."

Best Man Rigs Newlyweds' Bed To Tweet During Sex 272

Posted by samzenpus from the nice-feed dept.
When an UK man was asked to be the best man at a friend's wedding he agreed that he would not pull any pranks before or during the ceremony. Now the groom wishes he had extended the agreement to after the blessed occasion as well. The best man snuck into the newlyweds' house while they were away on their honeymoon and placed a pressure-sensitive device under their mattress. The device now automatically tweets when the couple have sex. The updates include the length of activity and how vigorous the act was on a scale of 1-10.

Exactly! Some managerial responsibility is in order. It's complete IDIOCY to not have a well-defined password management system in place & even more stupid to not have a series of contingencies in order. After all, THIS IS A FUCKING CIVIC INFRASTRUCTURE WE ARE TALKING ABOUT! For his part, Childs should not have even wanted to be the sole keeper of the passwords, although brilliant for job security, I guess. The fact that there was no oversight (i.e. no one smart enough to know what the fuck was going on) is just plain scary. Even scarier is that the guy has wasted part of his life in prison for it. seriously-wtf?!

Swarm — a New Approach To Distributed Computation 80

Posted by timothy from the or-old-approach-to dept.
An anonymous reader writes "Ian Clarke, creator of Freenet, has been working on a new open source project called Swarm. The concept is to allow a computer program to be distributed across multiple computers in a manner almost completely transparent to the programmer. The system observes the program executing and figures out how the workload should be distributed for maximum efficiency. Swarm is implemented in Scala. Its at an early-prototype stage, and Ian has created a good 36 minute video explaining the concept and the current implementation."

Is "Good Enough" the Future of Technology? 350

Posted by Soulskill from the seems-to-work-for-the-movie-industry dept.
himitsu writes "In an article titled 'The Good Enough Revolution: When Cheap and Simple Is Just Fine,' Wired claims that the future of technology, warfare and medicine will be filled with 'good enough' solutions; situations where feature-rich and expensive products are replaced with bare-bones infrastructures and solutions. 'We now favor flexibility over high fidelity, convenience over features, quick and dirty over slow and polished. Having it here and now is more important than having it perfect. These changes run so deep and wide, they're actually altering what we mean when we describe a product as "high-quality."'"

A Planet That Orbits Its Star the Wrong Way 257

Posted by timothy from the didn't-get-the-memo dept.
Smivs writes "BBC News is reporting that astronomers have discovered the first planet that orbits in the opposite direction to the spin of its star. Planets form out of the same swirling gas cloud that creates a star, so they are expected to orbit in the same direction that the star rotates. The new planet is thought to have been flung into its 'retrograde' orbit by a close encounter with either another planet or with a passing star. The work has been submitted to the Astrophysical Journal for publication. Co-author Coel Hellier, from Keele University in Staffordshire, UK, said planets with retrograde orbits were thought to be rare. 'With everything [in the star system] swirling around the same way and the star spinning the same way, you have to do quite a lot to it to make it go in the opposite direction.' Professor Hellier said a near-collision was probably responsible for this planet's unusual orbit. 'If you have a near-collision, then you'll have a large gravitational slingshot from that interaction,' he explained. 'This is the likeliest explanation. But it might be possible you can do it by gradually perturbing the orbit through the influence of a second planet. So far, we haven't found any evidence of a second planet there.'"
