3D Video Conferencing by 2020
Wednesday January 26th 2011, 9:53 pm
Researchers in Tucson, Arizona have nearly achieved real time holographic film. At present there is a two second delay from original filming to viewing the moving 3D image, but glitches are rapidly getting sorted and 3D television and live holographic images via the Internet is predicted for 2020.
The technology is made possible by a new type of plastic that can restore the image every two seconds. Sixteen cameras take simultaneous pictures of the object from slightly different view points to make up the whole 3 dimensional image. These pictures are transferred to a PC which processes the data which it converts into ‘hogels’ (Holographic pixels).
The hogels are then electronically sent to another PC where they are converted into an optical signal and broadcast by laser onto a plastic screen. When the laser light touches the plastic screen chemical reactions are produced that temporarily (2 seconds) show the image as previously recorded.
The plastic then instantly erases ready to receive the next image. This system occurs over and over again to show moving film, but with a two second ‘stutter’ delay.

PC is Still a Smart Bet
Friday January 15th 2010, 12:39 am
According to Microsoft chairman, Steve Ballmer, the PC is still the best smart device, which means there is still money to be made in the PC business, wheter it is in hardware, software or services for consumers.
Ballmer said the PC industry has never been in a better position. He said that analyst Gartner’s has revised its PC market analysis for 2009, from a 2% decline to 3% growth, representing 300 million new PCs shipped. Gartner predicts the PC market to grow in 2010 by 12%. “That’s an incredible number of smart devices,” Ballmer said, which he suggested was good news for businesses that rely on their customers having PCs.
In his keynote presentation, he discussed the increasing importance of change.
Regarding cloud computer, he said, “We believe in an approach that combines the power of intelligent software that runs on devices along with smart and intuitive services accessed instantly via the cloud.”
Thinking back over the past three decades, he said, “The things we take for granted today would have been considered science fiction previously.”
He also said that technology is playing a significant role in helping to tackle major global problems such as energy, climate change, healthcare and education. Ballmer said Microsoft was providing people with tools to help them ensure their homes were energy efficient.

Cloud Virtualisation is Security Key in 2010
Thursday January 07th 2010, 9:49 am
Industry experts say cloud computing and virtualization are set to be the biggest areas of development in security during 2010.
Increasing collaboration between suppliers is expected by businesses as cloud and virtualization technologies bring in a new way of thinking about and doing security.
Virtualising client devises that allow organizations to manage computer equipment more efficiently will bring a surge of interest. This will lead to the creation of “dual use” devices for work and home, according to Graham Titterington, principal analyst at Ovum.
Built-in security will enable faster virtualization and cloud adoption, but organizations must think security before any implementations, said Eric Domage, research analyst at IDC.
Peter Sommer, professor of security at the London School of Economics warned that businesses should watch out that the costs of authentication and confidentiality do not outweigh the benefits.
Cloud assurance levels for cloud services will be a hot topic and enterprises will have the opportunity to take the lead in this process, however, the future of IT security budgets is unclear. While IDC expects organizations to unfreeze and even restore budgets, others foresee continued cuts and constraints.
Regulation and compliance promises to be another important security consideration in 2010, but organizations should be wary of compliance at the expense of security.
Joshua coman, research director at the 451 Group said: “We now fear the auditor more than the attacker, but a myopic focus on compliance frameworks is dangerous.”
