About this Site
Moore’s Law defines the history of technology. It held that the number of circuits etched on a given piece of silicon could double every 18 months as far as its author, Intel co-founder Gordon Moore, could see. Moore’s Law has spawned constant revolutions since then, not just in computing but in communications, in science, in a host of areas. Moore’s Law applies to radios, and to optical fiber, but there are some areas where it doesn’t apply. In this blog we’ll take a daily look at new implications of Moore’s Law in real time, as it rolls forward to create our future.

Google's Biggest Achievement

Posted by Dana Blankenhorn

ZDNet has revealed Google's biggest technical achievement.

PCs crash, and Google deals with it.

Martin LaMonica got this from Urs Hoelzle, a vice president of engineering and of operations during the recent EclipseCon.

A key is its Google File System, designed to assume that a failure can happen at any time. Thus data is replicated in three places, and there is a "master" machine that can locate copies.

Here's the money quote. "If you can expect failures, then this is what makes cheap commodity PCs viable for Internet services."

Thus, Linux' biggest success story runs on proprietary software. Ironic, huh?
