For those of you who don't read Slashdot (probably nobody here), apparently Intel has created a site devoted to
energy-saving in Linux, which may be useful to those running Linux on laptops who want to get more out of their battery. The downloads site includes some utilities to find out what applications are causing the most power consumption, a kernel modification to help with CPU energy savings, and some other goodies. People from Slashdot claimed that this is no different than Intel's
PowerTop utility for Linux, only redesigned and with a snappier marketing sell.
It doesn't sound like it's incredibly useful, but it can probably help in a few ways.
