Whither Moore's Law; Introducing Koomey's Law 105

Joining the ranks of accepted submitters, Beorytis writes "MIT Technology review reports on a recent paper by Stanford professor Dr. Jon Koomey, which claims to show that the energy efficiency of computing doubles every 1.5 years. Note that efficiency is considered in terms of a fixed computing load, a point soon to be lost on the mainstream press. Also interesting is a graph in a related blog post that really highlights the meaning of the 'fixed computing load' assumption by plotting computations per kWh vs. time. An early hobbyist computer, the Altair 8800 sits right near the Cray-1 supercomputer of the same era."

Is SSD Density About To Hit a Wall? 208

Zombie Puggle writes "Enterprise Storage Forum has an article contending that solid state disks will stay stuck at 20-25nm unless the materials and techniques used to design Flash drives changes, and soon. 'Anything smaller and the data protection and data corruption issues become so great that either the performance is abysmal, the data retention period doesn't meet JEDEC standards, or the cost increases. Though engineers are working on performance and density improvements via new technologies (they're also trying to drive costs down), these are fairly new techniques and are not likely to make it into devices for a while."

IP Traffic To 'Double' Every Two Years 128

Stony Stevenson writes "Web traffic volumes will almost double every two years from 2007 to 2012, driven by video and web 2.0 applications, according to a report from Cisco Systems. Cisco's Visual Networking Index (PDF) predicts that visual networking will account for 90 percent of the traffic coursing through the world's IP networks by 2012. The upward trend is not only driven by consumer demand for YouTube clips and IPTV, according to the report, as business use of video conferencing will grow at 35 percent CAGR over the same period." I left the apostrophes around the word "double" in the title because the linked site has them, but for the life of me I can't figure out why.
