“Your time is limited, so don’t waste it living someone else’s life. Don’t be trapped by dogma – which is living with the results of other people’s thinking. Don’t let the noise of other’s opinions drown out your own inner voice. And most important, have the courage to follow your heart and intuition. They somehow already know what you truly want to become. Everything else is secondary.”
Steve Jobs (1955-2011)
Visible Light Communication uses light emitting diodes (LEDs), for the dual role of illumination and data transmission. Using the visible light spectrum, which is free and less crowded than other frequencies, wireless services can be piggy-backed over existing lighting installations. With this leading edge technology, data including video and audio, internet traffic, etc, can be transmitted at high speeds using LED light.
Prof Harald Haas leads the EPSRC-funded D-LIGHT project at the School of Electronics and Engineering at the University of Edinburgh.
Facebook has announced a partnership with Skype to add video chat to the social networking site.
The move is likely to be seen as a shot across the bow of Google, which recently launched a Facebook rival, Google+, also featuring video calling.
This is not the first time Facebook and Skype have teamed up – they already share some instant messaging tools.
Skype is in the process of being bought by Microsoft, which is a major shareholder in Facebook.

Over the past 30 years, designer, writer, and Microsoft researcher Bill Buxton has been collecting input and interactive devices whose design struck him as interesting, useful, or important.
In the process, he has assembled a good collection of the history of pen computing, pointing devices, touch technologies, watches, keyboards, mice, an electronic drum set, a 60-year-old transistor radio whose design inspired the iPod, a Nintendo Power Glove, several Etch-A-Sketches, and even the first so-called “smart” phone – controlled by a touch-screen – first shown in 1993, 14 years before smart phones exploded onto the scene, as well as an illustration of the nature of how new technologies emerge.
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.
IPv6 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.
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
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.
“A practical artificial leaf has been one of the Holy Grails of science for decades. We believe we have done it. And placed in a gallon of water and left in sun, these artificial leaves could provide a home in the developing world with basic electricity for a day,” Daniel Nocera, who led the team, said.
He added: “Our goal is to make each home its own power station. One can envision villages in India and Africa not long from now purchasing an affordable basic power system based on this technology.”
