Comment Dark Matter- does it collect in stars? Discuss (Score 1) 412

If dark matter is only affected (effected?) by gravity, would it tend to collect in massive bodies like planets, stars and black holes? Would that mean the gravitational constant could change locally depending on the amount of locally available dark matter? Could this have something to do with the shrinking mass of the standard kilogram?

NVIDIA Shows Off "Optimus" Switchable Graphics For Notebooks 102

Posted by Soulskill on Tuesday February 09, 2010 @01:49PM from the that's-some-prime-namespace dept.

Vigile writes "Transformers jokes aside, NVIDIA's newest technology offering hopes to radically change the way notebook computers are built and how customers use them. The promise of both extended battery life and high performance mobile computing has seemed like a pipe dream, and even the most recent updates to 'switchable graphics' left much to be desired in terms of the user experience. Having both an integrated and discrete graphics chip in your notebook does little good if you never switch between the two. Optimus allows the system to seamlessly and instantly change between IGP and discrete NVIDIA GPUs based on the task being run, including games, GPU encoding or Flash video playback. Using new software and hardware technology, notebooks using Optimus can power on and pass control to the GPU in a matter of 300ms and power both the GPU and PCIe lanes completely off when not in use. This can be done without being forced to reboot or even close out your applications, making it a hands-free solution for the customer."

Submission + - SCO blames Linux for bankruptcy filing 4

Submitted by Stony Stevenson on Monday September 17, 2007 @07:03PM

Stony Stevenson writes: SCO Group CEO Darl McBride says competition from the open source Linux operating system was a major reason why the company was forced to file for Chapter 11 bankruptcy protection on Friday.

In a court filing in support of SCO's bankruptcy petition, McBride noted that SCO's sales of Unix-based products "have been declining over the past several years." The slump, McBride said, "has been primarily attributable to significant competition from alternative operating systems, including Linux."

McBride listed IBM, Red Hat, Microsoft, and Sun Microsystems as distributors of Linux or other software that is "aggressively taking market share away from Unix."
