DuracellFan writes "Intel recently released its PowerTOP utility, which builds on work done by kernel developers to make the Linux kernel power-efficient. PowerTOP gives a snapshot of what apps are consuming the most power. The PowerTOP website also hosts patches for several Linux apps and the kernel. In the article, which also details PowerTOP, lead-developer, Arjan van de Ven of Intel, says that PowerTOP could soon show which applications keep the disk busy."
Why Linux Sucks (batteries)

An anonymous reader writes "Last July Dave Jones entertained the audience at the Ottawa Linux Symposium with a talk titled
Why Userspace Sucks in
which he described many hyperactive applications performing needless busywork.
Now Arjan van de Ven has come up with a tool named powertop that points the finger directly at which applications and device drivers are draining your laptop battery by waking the CPU from idle hundreds of times per second.
Low power states on modern processors can save significant amounts of power, but only if the cpu stays in the low power state for long enough to amortize the energy used to get into and out of the low power state. Powertop reports the total number of times the cpu is woken each second, the average time spent in each C-state, and the top ten offenders who wake the CPU from its slumbers.
Keith Packard reported that by using this tool to fix or eliminate the worst offenders he increased his battery life from four hours to almost seven!"

YouTube, MySpace banned on DoD computers

vivaoporto writes "The U.S. Department of Defense said it will block worldwide access to 13 websites including MySpace and YouTube Today from the unclassified defense Department Internet(NIPRNet), according to media reports.
The ban, which takes place immediately, actually was imposed in February and was not prompted by any event or study, according to Army Col. Gary Keck, a Defense Department spokesman. He confirmed that bandwidth was the issue and said the decision is "not about content."
The new policy takes effect as the military has, ironically, aggressively turned to YouTube as a means of broadcasting what it considers to be the more positive aspects of its work in Iraq and Afghanistan as a way of countering what it considers to be negative news coverage.
The sites blocked by the Defense Department: MySpace, YouTube, Metacafe, IFilm, StupidVideos, FileCabi, BlackPlanet, hi5, Photobucket, Pandora, MTV, 1.fm and Live365."
