“Our flat lens opens up a new type of technology,” says principal investigator Federico Capasso. “We’re presenting a new way of making lenses. Instead of creating phase delays as light propagates through the thickness of the material, you can create an instantaneous phase shift right at the surface of the lens. It’s extremely exciting.”" Link to Original Source top
yahyamf (751776) writes "My N900 recently broke and I'm looking for a replacement. The N9 looks great, despite not having a keyboard, but it seems that it will not have as many packages and developer interest as the N900. The iPhone is not an option as a matter of principle. I've never used Android before, and am a bit bewildered by the number of choices. Is there any particular phone the Slashdot crowd would recommend as a worthy replacement for the N900 both in functionality and spirit? Or should I wait for Tizen phones to appear?" top
yahyamf writes "I've been asked to help setup software for managing a small library at a non-profit school in the middle-east for under-privileged children. The library has about 5000 books and will be run mostly by student workers. The requirements are low cost, ease of use and maintenance, and support for Arabic and English. Barcode printing and scanning capabilities would be great as well. I've looked briefly at koha, but is there anything else out there (both hardware and software) slashdotters can recommend?" top
yahyamf (751776) writes "One Chinese company has proposed new buses that are so big they straddle the road, while cars drive beneath them. Designers at Shenzhen Hashi Future Parking Equipment Co., Ltd say that these behemoth buses solve a number of issues in one fell swoop, and would result in fewer traffic jams, less emissions, and faster travel.
These buses are actually being put into pilot use shortly. They should make their debut in Beijingâ½âsÂâs Mentougou district, where work is to commence on the first 186km of track at yearâ½âsÂâs end.
Each of the jumbo buses will measure 4 to 4.5 meters high, with passengers aboard the upper level and other vehicles lower than 2 meters going under. Powered by electricity and solar energy, the bus can carry 1,200 to 1,400 passengers at a time." Link to Original Source top
yahyamf writes "ASUS recently announced that their ASUS TeleSky(TM) telecom adaptor will now be included in some of their motherboards. The TeleSky telecom adaptor converts ordinary house phones into multi-functional Skype phones. With one jack connected to the house phone and the other linked to the ground telephone line, the TeleSky can switch the house phone connection between PSTN and VoIP networks.
While it sounds interesting, how would this compare to the dedicated VOIP adapters available from SIPURA and others?"
