An artificial leaf invented to solve the power crisis

Scientists have created the world’s first practical artificial leaf that can turn sunlight and water into energy, which they claim could pave the way for a cheaper source of power.
A team at Massachusetts Institute of Technology (MIT) says that the artificial leaf from silicon, electronics and various catalysts which spur chemical reactions within the device, can use sunlight to break water into hydrogen and oxygen which can then be used to create electricity in a separate fuel cell.

An important step toward realizing the dream of an inexpensive and simple “artificial leaf,” a device to harness solar energy by splitting water molecules, has been accomplished by two separate teams of researchers at MIT

IPV6... Are you Ready?

As IPv6 is around the corner and set to grow in the coming few years, are you ready for it yet?
Find out using this test if your network are ready for IPv6.
IPv6IPv6 is an IP address standard designed to replace the current IPv4 protocol, which has been in use since the 1980s for routing Internet traffic. The new protocol has been available for several years now and supports several magnitudes more address spaces than IPv4, while also providing better security and reliability.
For more than 30 years, 32-bit addresses have served us well,but the growth of the Internet has mandated a need for more addresses than is possible with IPv4. IPv6 allows for vastly more addresses. IPv6 is the only long-term solution,  it has not yet been widely deployed. With IPv4 addresses expected to run out in 2011, only 0.2% of Internet users have native IPv6 connectivity.

Microsoft shows off new operating system

Microsoft Corp showed off a version of the software company's next operating system, highlighting touchscreen features that would work well on a tablet computer, at the All Things Digital technology conference on Wednesday.
The head of Microsoft's Windows unit, Steven Sinofsky, said the product did not yet have a name, and did not say when it would be released.
In a demonstration at the D9 conference in Palos Verdes, California, a Microsoft employee showed a starting page that resembles Microsoft's latest phone software, with live 'tiles' manipulated by pressing and swiping the screen.
The demonstration shows Microsoft is making progress toward running its operating system on tablets which may be able to rival Apple Inc's iPad, launched 14 months ago.
The demo comes five months after Sinofsky showed off a very crude version of the new Windows system working on ARM Holdings chips on at the Consumer Electronics Show in January.
