Comment I doubt it is for *chips* themselves (Score 3, Interesting) 90

TFA is a bit light on details, but (having heard of GaN before), it is good at handling large voltages/currents, and they are probably talking about more efficient power supplies (saving 20%, apparently), not replacing Si in logic chips. Or maybe integrating power conversion onto processor die itself, but the latter is still made of good old CMOS. Currently, from what I've heard, a good chunk of pins on your processor are used to supply power -- if you think of it, 30W processor with 3V bias needs to get 10A of current.

US Military Stepping Up Use of Directed Energy Weapons 83

An anonymous reader writes: At a conference on Tuesday, U.S. officials explained that all branches of the military would be increasing their use of lasers and other directed energy weapons. Lieutenant General William Etter said, "Directed energy brings the dawn of an entirely new era in defense." The Navy's laser deployment test has gone well, and they're working on a new prototype laser in the 100-150 kilowatt range. "[Navy Secretary Ray] Mabus said Iran and other countries were already using lasers to target ships and commercial airliners, and the U.S. military needed to accelerate often cumbersome acquisition processes to ensure that it stayed ahead of potential foes."

But knowing to not shoot selfies of yourself being a total jackass is something that can make some sense a lot earlier than 18. If some 15 year old can know enough not to drop his pants in front of his grandmother or in front of his classroom at school, he already has what it takes to know not to do it online.

Mod this up. (I've already posted in the thread, so I can't.)

Yes because total control of the commons worked SOOO well for the Soviet Union and their satellites. Governments with total common ownership are responsible for the worst ecological catastrophies in history. Even today, China, with total control of their energy industry, has the worst air pollution in the world.

Face it, the idea that command and control is the only way is a total lie. An open and free market for technological innovation will save the environment, not mimicking failed God damned central planning from last century.

You could look into Lustre, although it would change your hardware configuration a bit (its not a SAN) Depending on your configuration and desired redundancy, this will affect costs a bit (i.e.. more luster nodes).

You could by a traditional SAN and tie it all together with fibre, though you'd need a clustered file system like Stornext, or another commercial CFS, or even GFS if you prefer open source. This would help solve your traversal of the system as a regular directory structure issue.

Best bet for backup would be to a robot tape library of some sort. There is some work being done on dynamic backup of data in Luster systems in the HPC space, but its not very mature. CFS systems like Sternest have methods in place for automatically backing up data on the filesystem.
