rev_media writes: The Real ID acts mandates all states to begin issuing federal IDs to all citizens by 2008. Costs could be as much at $14 billion, but only 40 million are currently allocated. Several states have passed legislation expressly forbidding participation in the program, while others seem to be all for it. The IDs will be required for access to all federal areas including flights, state parks and federal buildings. People in states refusing to comply will need to show passports even for domestic flights.

The small size of nanoscale crystals results in the conversion of this energy into electrons instead of heat. Solar cells made of silicon nanocrystals could theoretically reach more than 40% efficiency, compared to 20% efficiency of the best conventional silicon solar cells.
An article in the Tech Review goes into more detail."

dch writes: In my office I am known as the Linux zealot. A co-worker of mine came up with an idea to pit Linux against Windows. We decided that we would do clean installs of Windows and Linux on several boxes and see how much of the hardware works with out having to install extra drivers or any other software. As an exercise before we do anything I was wondering how many drivers does Windows XP come with vs Linux, with out installing anything else? I found www.linux-drivers.org, however I was wanting just a list of all hardware supported by Linux. And is there any site that will list want drivers come with Windows Xp?
