A detailed examination of the Pentium's ×3 circuit, explaining its purpose, implementation, and the advanced techniques used to maximize performance.
This webpage discusses the electronic publication of W. Ross Ashby's seminal work 'Introduction to Cybernetics', originally published in 1956. Principia Cybernetica has made this classic text available online, thanks to permissions from the Ashby estate, allowing for wide access. The book is praised for its clear, simple, yet profound insights into cybernetics and systems theory, introducing fundamental concepts like the homeostat, the law of requisite variety, and the principle of self-organization. It's formatted as a PDF for easy reading and printing.
MIT's Tech Square has played a significant role in the evolution of computing, hosting key figures and research from time-shared computing to the World Wide Web.

A command structure for complex information processing1
J. C. Shaw / A. Newell / H. A. Simon / T. O. Ellis
The general-purpose digital computer, by virtue of its large capacity and general-purpose nature, has opened the possibility of research into the nature of complex mechanisms per se. The challenge is obvious: humans carry out information processing of a complexity that is truly baffling. Given the urge to understand either how humans do it, or alternatively, what kinds of mechanisms might accomplish the same tasks, the computer is turned to as a basic research tool. The varieties of complex information processing will be understood when they can be synthesized: when mechanisms can be created that perform the same processes.
