Well, it's a start. As soon as they find a way to refresh the state at a regular frequency we'll be able to store (not just transmit) information with light. I hope it involves the use of tiny, tiny mirrors. =P
Aviran was one of many readers to submit news of a just-announced development in the ongoing quest to develop a working invisibility cloak, writing: "Scientists say they are a step closer to developing materials that could render people and objects invisible. Researchers have demonstrated for the first time they were able to cloak three-dimensional objects using artificially engineered materials that redirect light around the objects. Previously, they only have been able to cloak very thin two-dimensional objects" Reader bensafrickingenius adds a link to coverage at the Times Online, and notes that "the world's two leading scientific journals, Science and Nature, are expected to report the results this week." Tjeerd adds a link to a Reuters' story carried by Scientific American.
mikesd81 writes "Engadget reports Apple has readied a blacklisting system which allows the company to remotely disable applications on your device. It seems the new 2.x firmware contains a URL which points to a page containing a list of 'unauthorized' apps — a move which suggests that the device makes occasional contact with Apple's servers to see if anything is amiss on your phone. Jonathan Zdziarski, the man who discovered this, explains, 'This suggests that the iPhone calls home once in a while to find out what applications it should turn off. At the moment, no apps have been blacklisted, but by all appearances, this has been added to disable applications that the user has already downloaded and paid for, if Apple so chooses to shut them down. I discovered this doing a forensic examination of an iPhone 3G. It appears to be tucked away in a configuration file deep inside CoreLocation.'" Update: 08/11 13:07 GMT by T : Reader gadgetopia writes with a small story at IT Wire, citing an interview in the Wall Street Journal, in which this remote kill-switch is "confirmed by Steve Jobs himself."
Da Massive writes with this excerpt from ComputerWorld: "For a technology that has been in stable release since May 22, 2000, PHP 4 has finally reached the end of its official life. With the release of PHP 4.4.9, official support has ended and the final security patch for the platform issued. ...With eight years of legacy code out there, it is likely that there are going to be a fairly large number of systems that will not migrate to PHP 5 in the near future, and a reasonable proportion of those that will not make the migration at all. For those who are not able to migrate their systems to the new version of PHP, noted PHP security expert Stefan Esser will continue to provide third party security patching for the PHP 4 line through his Suhosin product."
Hugh Pickens brings news that scientists from Penn State have developed a new method for heat-transfer that may replace the common compressor-based system used in household appliances. Quoting: "Zhang's approach uses the change from disorganized to organized that occurs in some polarpolymers when placed in an electric field. The natural state of these materials is disorganized with the various molecules randomly positioned. When electricity is applied, the molecules become highly ordered and the material gives off heat and becomes colder. When the electricity is turned off, the material reverts to its disordered state and absorbs heat. The researchers report a change in temperature for the material of about 22.6 degrees Fahrenheit... Repeated randomizing and ordering of the material combined with an appropriate heat exchanger could provide a wide range of heating and cooling temperatures."
avatar4d writes "Networkworld is reporting about a warballooning operation (similar to wardriving) that was disallowed by the management at the Riviera Hotel in Las Vegas, but was covertly launched anyway. The team found approximately 370 networks, and about a third of those were unsecured. In addition to that, the project managed to show how trusting the local law enforcement agencies really were: 'Near the end of the operation, a Las Vegas Metropolitan Police cruiser drove by the parking lot to see what was going on. Hill and his team waved. The police officers waved back and drove off.'"
