That invisibility cloak Harry Potter throws around himself to hide in plain sight soon may be fact, rather than fiction. Researchers at the University of Texas in Austin have demonstrated one — sort of. The researchers hid an 18 cm cylindrical tube from microwaves by putting it in a shell of plasmonic metamaterial. Metamaterials are artificial materials engineered to have properties that may not occur in nature. Plasmonic metamaterials are negative index metamaterials, meaning they are, in essence, invisible at a certain frequency range.

Vignette differentiates itself from other Android-based camera apps by adding cross-process, tilt-shift, double exposure and other sophisticated effects like infrared, as opposed to the general toy camera and retro effects commonly found. The paid version of Vignette adds full resolution to the mix. I had been using the free version for some months and loved the app, but was disappointed with the resolution delivered, when I discovered that you had to buy the full version to utilize the full resolution of your phone. The full version has exceeded my expectations.

Symantec is sounding the alarm for users of its pcAnywhere remote access software following threats from a hacker. In some cases, said the security software maker, they might want to turn off and disable the application entirely. The hacker, who goes by the handle “YamaTough,” might be a member of the hacker collective Anonymous. The hacker claimed last week to have released pcAnywhere source code to the wild, where it could be exploited by malicious hackers.

Slingbox lets you watch your television remotely. The Slingbox hardware device captures the source image and audio at your home and squirts it into the Internet. Proprietary software is used to replicate a television-like experience on laptops or other devices like smartphones. Hardware-based infrared transmitters create remote control commands and viewing can take place within the home’s network, or globally across the Internet, including mobile data networks.
Google will consolidate about 60 of its privacy policies across its products in March, creating one overarching policy and leaving only about another 10 unchanged for legal and other reasons. The company is also changing its terms of service. It may combine information on Google account holders across all the company’s services the account holder uses. This will provide a simpler, more intuitive Google experience and also let the company serve users better, it claims.
WikiLeaks founder Julian Assange has plans to host a new TV show called “The World Tomorrow.” The half-hour weekly episodes are scheduled to begin airing in mid-March on Russia’s English-language RT channel. It will reach some 60 million global viewers.
Assange sees the series as a vehicle to discuss the issues of the day with the people who are shaping the future “in a deeper and clearer way than has been done before.” It can be assumed, though, that Assange and Wikileaks have goals that go beyond discussions of pressing issues.
Encrypting data on your computer may protect you from hackers and thieves, but it won’t protect you from crime investigators. That was the finding of a federal district court in Colorado Monday in a case involving a woman who refused to decrypt the files on her laptop for government prosecutors. The woman, Romona Fricosu, of Peyton, Colo., denied prosecutors’ demand to decrypt the files on the grounds that doing so would violate her Fifth Amendment rights. She argued that forcing her to use her password to decrypt the files was tantamount to self-incrimination, which is prohibited by the constitution.
