Editorial Pointers

Silicon-based technology has dominated the computing field since its inception, but changes are afoot. In recent years a swell of new computing paradigms have emerged, and while all are very different and all in their infancy, all are decidedly silicon-free. This month’s special section examines the current state of several of these non-traditional computing paradigms, […]

A team of roboticists are using the lessons of 1930s physiologist Nikolai Bernstein to build the world’s fastest walking robot. BBC News reports Runbot, a self-learning, dynamic robot, is helping scientists unravel the mystery of walking. The small, bipod robot can move at speeds of more than three leg lengths per second, slightly slower than […]

Two points seemed to be missing from Abbe Mowshowitz’s and Nanda Kumar’s "Viewpoint" "Public vs. Private Interest on the Internet" (July 2007). For one, while they quoted Edward Whitacre’s (in)famous comment about Google, Vonage, and other content providers not paying AT&T for access, they failed to point out the fallacy of Whitacre’s argument, something that, […]

Evolving the ACM Journal Distribution Program

ACM’s Digital Library (DL) has become an enormously effective mechanism for the distribution of research articles and related material in the field of computing. The DL’s wide availability and associated facilities have greatly reduced the need, and demand, for producing research publications in print. Thus, ACM has been working to position its publications program to […]

Research and Advances Beyond silicon: new computing paradigms Sep 1 2007

The meaning and implementation of the term "computing" has changed greatly since ACM was first organized 60 years ago. This special section presents overview articles collectively called "non-silicon-based new computing paradigms." Although these paradigms often differ from one another significantly, there are three common characteristics: the techniques are not based on the traditional silicon-based integrated circuit technology; the basic computing elements have been physically implemented, meaning they are not just theory; and many of them aim at miniaturization, often on the order of 1--100 nanometers. Here, the term "computing" is employed in a very broad sense.
