serutan writes "Using lasers to drive spaceships has been a subject of interest for many years, but making a photonic engine powerful enough for practical use has been elusive. Dr. Young Bae, a California physicist, has built a demonstration photonic laser thruster that produces enough thrust to micro-maneuver a satellite. This would be useful in high-precision formation flying, such as using a fleet of satellites to form a space telescope with a large virtual aperture. Scaled up, a similar engine could speed a spacecraft to Mars in less than a week."

srizah writes to mention that Toshiba plans to launch a 51 GB HD DVD, with a 1 GB advantage over Sony's Blu-ray disc. From the article: Toshiba has submitted a triple-layer, 51GB HD DVD-ROM disc to the standard's overseer in the hope the technology will be adopted as a standard by the end of the year. If approved, it allow the format to exceed the 50GB storage capacity of rival medium Blu-ray Disc. The HD DVD standard currently defines single- and dual-layer discs capable of holding 15GB and 30GB of data, respectively."

don_combatant writes to note that President Bush claimed new powers to search US mail without a warrant. He made this claim in a "signing statement" at the time he signed a postal overhaul bill into law on December 20. The signing statement directly contradicts part of the bill he signed, which explicitly reinforces protections of first-class mail from searches without a court's approval. According to the article, "A top Senate Intelligence Committee aide promised a review of Bush's move."

An anonymous reader writes, "Karl Bode of Broadband Reports takes aim at supposed telecom experts and think tankers who profess to love the 'free market,' but want to ban the country's un-wired towns and cities from offering broadband to their residents. If you didn't know, incumbent providers frequently determine towns and cities unprofitable to serve (fine), but then turn around and lobby for laws that make it illegal to serve themselves (not so fine). They then pay experts to profess their love for a free market and deregulation — unless that regulation helps their bottom line. A simple point: 'Strange how such rabid fans of a free-market wouldn't be interested in allowing market darwinism to play out.'"

arcon5 writes "After several months of silence it was more or less accepted that Microsoft wasn't going to do anything about the firmware hacks that allow Xbox 360s to play backups. Rather surprising, considering the 'inventor' of the hack confirmed in March already that the mods are easily detectable, and the reports that piracy is running rampant in countries like China. It appears that Microsoft is finally taking action against them though, although they may be hitting the wrong persons." Best part of that article is the firmware chip encased in epoxy.

fiorenza writes "Ars Technica spoke with Microsoft concerning the controversial changes in Windows Vista's licensing, and they have learned that Vista will permit one 'significant' hardware change before requiring users to either appeal to Microsoft support or purchase another license. Automatic re-activation online will fail after one use. Microsoft is using a new algorithm to monitor hardware changes and enforce licensing compliance, and the company says that it is more forgiving now than it was with Windows XP."
