Design of a Primitive Nanofactory
This 86-page paper, published in October 2003, was written by the Director of Research at the Center for Responsible Nanotechnology. He proposes "an architecture for combining large numbers of programmable mechanochemical fabricators into a manufacturing system, or nanofactory, capable of producing a wide range of human-scale products." Rather than calling for the development of entirely new technologies, the author attempts to describe a system that can be built with current engineering practic

Rewind, Repair, Replay: Three R's to Dependability
One of the most important features in current software applications is the undo command, which allows users to revert to previous states in their documents. A relatively unexplored concept involves system undo, a method of restoring settings in a system that were accidentally changed by the operator. This research paper discusses "a model of undo that matches the needs of human error recovery and retroactive repair." The authors begin by explaining the growing importance of such a mechanism and
