Bay Area To Install Electric Vehicle Grid 388

Mike writes "Recently San Francisco, San Jose, and Oakland unveiled a massive concerted effort to become the electric vehicle capitol of the United States. The Bay Area will be partnering with Better Place to create an essential electric vehicle infrastructure, marking a huge step towards the acceptance of electric vehicles as a viable alternative to those that run on fossil fuels." Inhabitat.com has some conceptual illustrations and a map showing EV infrastructure, such as battery exchange stations, stretching from Sacramento to San Diego — though this is far more extensive than the Bay Area program actually announced, which alone is estimated to cost $1 billion.

Submission + - What is preventing FLOSS Nvidia 3D Drivers? 1

Slithe writes: What information is Nvidia not providing that would allow one to write FLOSS drivers for Nvidia cards? I am not an expert on this topic, so this is why I am asking Slashdot. A modern graphics card is basically a piece of hardware that can do matrix and vector operations very quickly, and modern graphics cards are programmable with shaders. I know that Nvidia graphics cards use the GPU assembly language, whose instructions are available and form the basis of writing shaders. I also know that X.Org has an open-source Nvidia driver for basic (i.e. not 2d or 3d accelerated) operation of the graphics card. Could someone take the Mesa OpenGL library and write a shader or set of shaders for every OpenGL function that the card should accelerate? What am I not seeing that would allow this to work?
