The Fascinating Influence of Cyclone
In 2001, Trevor Jim (AT&T Research) and Greg Morrisett (Cornell) launched a joint project to develop a safe dialect of the C programming language, an outgrowth of earlier work on Typed Assembly Language. After five years of hard work and some published papers, the team (including Dan Grossman, Michael Hicks, Nik Swamy, and others) released Cyclone 1.0. And then the developers moved on to other things.
Few have heard of Cyclone and almost no one has used it.
