Ruby has taken the programming world by storm. With the slow decline of Java and the catalyst of Rails, it has risen to become one of the most popular programming languages, rising to #10 on the TIOBE index and winning their "Programming Language of the Year" award.

This book describes a method for writing concurrent computer programs of high quality. It is written for professional programmers and students who are faced with the complicated task of building reliable computer operating systems or real-time control programs.

The motivations for mastering concurrent programming are both economic and intellectual. Concurrent programming makes it possible to use a computer where many things need attention at the same time--be they people at terminals or temperatures in an industrial plant. It is without doubt the most difficult form of programming.

This book tries to give students of computer science and professional programmers a general understanding of operating systems--the programs that enable people to share computers efficiently.

To make the sharing of a computer tolerable, an operating system must enforce certain rules of behavior on all its users. One would therefore expect the designers of operating systems to do their utmost to make them as simple, efficient, and reliable as possible.

From volume 1 Preface

This book is intended for a one or two semester course in compiling theory at the senior or graduate level. It is a theoretically oriented treatment of a practical subject. Our motivation for making it so is threefold.

In recent years there has been an increasing interest in the art of computer programming, the conceptual tools available for the design of programs, and the prevention of programming oversights and error. The initial outstanding contribution to our understanding of this subject was made by E. W. Dijkstra, whose Notes on Structured Programming form the first and major section of this book.

This book presents the theory of formal languages as a coherent theory and makes explicit its relationship to automata. The book begins with an explanation of the notion of a finite description of a language. The fundamental descriptive device--the grammar--is explained, as well as its three major subclasses--regular, context-free, and context-sensitive grammars. The context-free grammars are treated in detail, and such topics as normal forms, derivation trees, and ambiguity are covered. Four types of automata equivalent to the four types of grammars are described.

Expanding on themes first raised in his tour-de-force, Running Money, Andy Kessler unpacks the entire history of Silicon Valley and Wall Street, from the industrial revolution to computers, communications, money, gold and stock markets. These stories cut [by an unscrupulous editor] from the original manuscript were intended as a Primer on the ways in which new technologies develop from unprofitable curiosities to essential investments.

What sets this book apart from others on logic programming is the breadth of its coverage. The authors have achieved a fine balance between a clear and authoritative treatment of the theory and a practical, problem-solving approach to its applications. This edition introduces major new developments in a continually evolving field and includes such topics as concurrency and equational and constraint logic programming.

The most complicated aspect of large software projects is not the implementation, it is the real world domain that the software serves. Domain Driven Design is a vision and approach for dealing with highly complex domains that is based on making the domain itself the main focus of the project, and maintaining a software model that reflects a deep understanding of the domain. The vision was brought to the world by Eric Evans in his book "Domain Driven Design". Eric's work was based on 20 years of widely accepted best practices in the object community, as well as Eric's own insights.
