Scientists Claim Breakthrough On Holographic Display 123

SpuriousLogic writes to tell us that University of Arizona researchers claim to have broken a barrier in holographic technology by creating an updatable, three-dimensional display with memory. While the existing model is only able to update once every couple of minutes, and isn't particularly suited for 3d images, it is certainly a step in the right direction. "Peyghambarian is also optimistic that the technology could reach the market within five to ten years. He said progress towards a final product should be made much more quickly now that a rewriting method had been found. However, it is fair to say not everyone is as positive about this prospect as Peyghambarian. Lecturer in Electronic Engineering at Bangor University in Wales, Dr Justin Lawrence, told CNN small steps were always being made on technology like 3D holograms, but, he couldn't see it being ready for the market in the next ten years."

Moving Beyond Passwords For Security 235

Naturalist writes with an excerpt from a New York Times story about the need for a more secure method for identification than the password-based system almost everyone currently uses. The article also discusses the weaknesses of the OpenID initiative to simplify the process. "The solution urged by the experts is to abandon passwords -- and to move to a fundamentally different model, one in which humans play little or no part in logging on. Instead, machines have a cryptographically encoded conversation to establish both parties' authenticity, using digital keys that we, as users, have no need to see. ...OpenID offers, at best, a little convenience, and ignores the security vulnerability inherent in the process of typing a password into someone else's Web site. Nevertheless, every few months another brand-name company announces that it has become the newest OpenID signatory."

Hektor_Troy writes: The New York Times' foreign-affairs columnist Thomas L. Friedman has written an op-ed column comparing energy policies between Denmark and the United States in which he wonders why Denmark, ranked 28th in the world by GDP, has been able to not only prosper with their high energy prices, when the US (dwarfing Denmark's GDP 44 times over) seems unable to cope properly under rising oil prices. Interesting point — Denmark's prime minister's idea of handling the rising oil prices is to raise taxes on it even more to make more people seek out alternatives.
