Paint-on Laser Brings Optical Computing Closer 132

holy_calamity writes "New Scientist has a story about a laser made by painting a solution of semiconductor crystals onto glass. It could be used to break the interconnect barrier by having optical interconnects, the interconnect barrier threatens Moore's law unless a faster way of connecting chips is found."

Code for Unbreakable Quantum Encryption 210

An anonymous reader writes "ITO is running a story on NIST's latest quantum encryption key generation. From the article: 'Raw code for "unbreakable" quantum encryption has been generated at record speed over optical fiber at NIST. The work is a step toward using conventional high-speed networks such as broadband Internet and local-area networks to transmit ultra-secure video for applications such as surveillance.'"

OS Virtualization Interview 184

VirtualizationBuff writes "KernelTrap has a fascinating interview with Andrey Savochkin, the lead developer of the OpenVZ server virtualization project. In the interview Savochkin goes into great detail about how virtualization works, and why OpenVZ outshines the competition, comparing it to VServer, Xen and User Mode Linux. Regarding virtualization, Savochkin describes it as the next big step, 'comparable with the step between single-user and multi-user systems.' Savochkin is now focused on getting OpenVZ merged into the mainline Linux kernel."

Philips Patents Technology to Force Ad Viewing 823

An anonymous reader writes "According to New Scientist, Philips has filed a patent for technology to force viewers to watch the ads in a program. Basically they plan to add extra flags to the Multimedia Home Platform that would stop controls from working until the ads are finished." From the article: "Philips' patent acknowledges that this may be 'greatly resented by viewers' who could initially think their equipment has gone wrong. So it suggests the new system could throw up a warning on screen when it is enforcing advert viewing. The patent also suggests that the system could offer viewers the chance to pay a fee interactively to go back to skipping adverts."

Torvalds Creates Patch for Cross-Platform Virus 195

Newsforge is reporting that Linus Torvalds took a few minutes to review the cross-platform proof of concept virus covered yesterday and has proven that the virus does indeed not work with latest kernel version 2.6.16 and even released a patch in order to fix this "problem." From the article: "The reason that the virus is not propagating itself in the latest kernel versions is due to a bug in how GCC handles specific registers in a particular system call. [...] So the virus did a number of strange things to make this show up, but on the other hand the kernel does try to avoid touching user registers, even if we've never really _guaranteed_ that. So the 2.6.16 effect is a mis-feature, even if a _normal_ app would never care. It just happened to bite the infection logic of your virus thing."
