Since the summer of 1973, when I became a Burroughs Research Fellow, my life has been very different from what it had been before. The daily routine changed: instead of going to the University each day, where I used to spend most of my time in the company of others, I now went there only one day a week and was most of the time -that is, when not travelling!- alone in my study. In my solitude, mail and the written word in general became more and more important. The circumstance that my employer and I had the Atlantic Ocean between us was a further incentive to keep a fairly complete record of what I was doing. The public part of that output found its place in what became known as "the EWD series", which can be viewed as a form of scientific correspondence, possible since the advent of the copier. (That same copier makes it hard to estimate its actual distribution: I myself made about two dozen copies of my texts, but their recipients were welcome to act as further nodes of the distribution tree. ) The decision to publish a se1ection from the EWD series in book form was at first highly embarrassing, but as the months went by I got used to the idea. As soon as some guiding principles had been adopted -preferably not published elsewhere, as varied and as representative as possible, etc.

I have always been fascinated with engineering. From Roman bridges and jumbo jets to steam engines and CD players, it is the privilege of the en gineer to combine scientific insights and technical possibilities into useful and elegant products. Engineers get a great deal of satisfaction from the usefulness and beauty of their designs. Some of these designs have a major impact on our daily lives, others enable further scientific insights or shift limits of technology. The successful engineer is familiar with the scientific basis of the field and the technology of the components, and has an eye for the envisioned applications. For example, to build an airplane, one had better understand the physics of motion, the structural properties of alu minum, and the size of passengers. And the physics of motion requires a mastery of mathematics, in particular calculus. Computers are a marvel of modern engineering. They come in a wide variety and their range of applications seems endless. One of the charac teristics that makes computers different from other engineering products is their programmability. Dishwashers have some limited programming capa is not the key part of the device. Their essential part is some bility, but it enclosed space where the dishes are stored and flushed with hot water. Computers are embedded in many different environments, but in their case the programming capability is the essential part. All computers are programmed in more or less the same way.

Here, the authors propose a method for the formal development of parallel programs - or multiprograms as they prefer to call them. They accomplish this with a minimum of formal gear, i.e. with the predicate calculus and the well- established theory of Owicki and Gries. They show that the Owicki/Gries theory can be effectively put to work for the formal development of multiprograms, regardless of whether these algorithms are distributed or not.

This classroom-tested textbook presents an active-learning approach to the foundational concepts of software design. These concepts are then applied to a case study, and reinforced through practice exercises, with the option to follow either a structured design or object-oriented design paradigm. The text applies an incremental and iterative software development approach, emphasizing the use of design characteristics and modeling techniques as a way to represent higher levels of design abstraction, and promoting the model-view-controller (MVC) architecture. Topics and features: provides a case study to illustrate the various concepts discussed throughout the book, offering an in-depth look at the pros and cons of different software designs; includes discussion questions and hands-on exercises that extend the case study and apply the concepts to other problem domains; presents a review of program design fundamentals to reinforce understanding of the basic concepts; focuses on a bottom-up approach to describing software design concepts; introduces the characteristics of a good software design, emphasizing the model-view-controller as an underlying architectural principle; describes software design from both object-oriented and structured perspectives; examines additional topics on human-computer interaction design, quality assurance, secure design, design patterns, and persistent data storage design; discusses design concepts that may be applied to many types of software development projects; suggests a template for a software design document, and offers ideas for further learning. Students of computer science and software engineering will find this textbook to be indispensable for advanced undergraduate courses on programming and software design. Prior background knowledge and experience of programming is required, but familiarity in software design is not assumed.

This booklet presents a reasonably self-contained theory of predicate trans former semantics. Predicate transformers were introduced by one of us (EWD) as a means for defining programming language semantics in a way that would directly support the systematic development of programs from their formal specifications. They met their original goal, but as time went on and program derivation became a more and more formal activity, their informal introduction and the fact that many of their properties had never been proved became more and more unsatisfactory. And so did the original exclusion of unbounded nondeterminacy. In 1982 we started to remedy these shortcomings. This little monograph is a result of that work. A possible -and even likely- criticism is that anyone sufficiently versed in lattice theory can easily derive all of our results himself. That criticism would be correct but somewhat beside the point. The first remark is that the average book on lattice theory is several times fatter (and probably less self contained) than this booklet. The second remark is that the predicate transformer semantics provided only one of the reasons for going through the pains of publication.

From the man who is practically synonymous with the form of the modern personal essay comes a delightful collection of prose, poems, and never-before-published pieces that span his career as an essayist, novelist, poet, film critic, father, son, and husband. Organized in six parts (Childhood; Youth; Early Marriage and Bachelorhood; Teaching and Work; Fiction; Politics, Religion, Movies, Books, Cities; The Style of Middle Age) Getting Personal tells two stories: the development of Lopate's career as a writer and the story of his life.

This book presents a unified collection of concepts, tools, and techniques that constitute the most important technology available for the design and implementation of information systems. The framework for this integration goal is the one offered by the relational model of data, its applications, and implementations in multiuser and distributed environments. This book attempts to develop an integrated methodology for the relational approach and various research and practical developments related to that approach.
