Book Synopsis Selected Writings on Computing: A personal Perspective by : Edsger W. Dijkstra
Download or read book Selected Writings on Computing: A personal Perspective written by Edsger W. Dijkstra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 381 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis On a Method of Multiprogramming by : W.H.J. Feijen
Download or read book On a Method of Multiprogramming written by W.H.J. Feijen and published by Springer Science & Business Media. This book was released on 1999-06-11 with total page 396 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Book Synopsis Computational Thinking: A Perspective on Computer Science by : Zhiwei Xu
Download or read book Computational Thinking: A Perspective on Computer Science written by Zhiwei Xu and published by Springer Nature. This book was released on 2022-01-01 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: This textbook is intended as a textbook for one-semester, introductory computer science courses aimed at undergraduate students from all disciplines. Self-contained and with no prerequisites, it focuses on elementary knowledge and thinking models. The content has been tested in university classrooms for over six years, and has been used in summer schools to train university and high-school teachers on teaching introductory computer science courses using computational thinking. This book introduces computer science from a computational thinking perspective. In computer science the way of thinking is characterized by three external and eight internal features, including automatic execution, bit-accuracy and abstraction. The book is divided into chapters on logic thinking, algorithmic thinking, systems thinking, and network thinking. It also covers societal impact and responsible computing material – from ICT industry to digital economy, from the wonder of exponentiation to wonder of cyberspace, and from code of conduct to best practices for independent work. The book’s structure encourages active, hands-on learning using the pedagogic tool Bloom's taxonomy to create computational solutions to over 200 problems of varying difficulty. Students solve problems using a combination of thought experiment, programming, and written methods. Only 300 lines of code in total are required to solve most programming problems in this book.
Book Synopsis Computability and Complexity by : Neil D. Jones
Download or read book Computability and Complexity written by Neil D. Jones and published by MIT Press. This book was released on 1997 with total page 494 pages. Available in PDF, EPUB and Kindle. Book excerpt: Computability and complexity theory should be of central concern to practitioners as well as theorists. Unfortunately, however, the field is known for its impenetrability. Neil Jones's goal as an educator and author is to build a bridge between computability and complexity theory and other areas of computer science, especially programming. In a shift away from the Turing machine- and G�del number-oriented classical approaches, Jones uses concepts familiar from programming languages to make computability and complexity more accessible to computer scientists and more applicable to practical programming problems. According to Jones, the fields of computability and complexity theory, as well as programming languages and semantics, have a great deal to offer each other. Computability and complexity theory have a breadth, depth, and generality not often seen in programming languages. The programming language community, meanwhile, has a firm grasp of algorithm design, presentation, and implementation. In addition, programming languages sometimes provide computational models that are more realistic in certain crucial aspects than traditional models. New results in the book include a proof that constant time factors do matter for its programming-oriented model of computation. (In contrast, Turing machines have a counterintuitive "constant speedup" property: that almost any program can be made to run faster, by any amount. Its proof involves techniques irrelevant to practice.) Further results include simple characterizations in programming terms of the central complexity classes PTIME and LOGSPACE, and a new approach to complete problems for NLOGSPACE, PTIME, NPTIME, and PSPACE, uniformly based on Boolean programs.

Book Synopsis Predicate Calculus and Program Semantics by : Edsger W. Dijkstra
Download or read book Predicate Calculus and Program Semantics written by Edsger W. Dijkstra and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Computer Systems by : Randal E.. Bryant
Download or read book Computer Systems written by Randal E.. Bryant and published by . This book was released on 2013-07-23 with total page 962 pages. Available in PDF, EPUB and Kindle. Book excerpt: For Computer Systems, Computer Organization and Architecture courses in CS, EE, and ECE departments. Few students studying computer science or computer engineering will ever have the opportunity to build a computer system. On the other hand, most students will be required to use and program computers on a near daily basis. Computer Systems: A Programmer's Perspective introduces the important and enduring concepts that underlie computer systems by showing how these ideas affect the correctness, performance, and utility of application programs. The text's hands-on approach (including a comprehensive set of labs) helps students understand the under-the-hood operation of a modern computer system and prepares them for future courses in systems topics such as compilers, computer architecture, operating systems, and networking.

Book Synopsis From Naked Ape to Superspecies by : David Suzuki
Download or read book From Naked Ape to Superspecies written by David Suzuki and published by Greystone Books Ltd. This book was released on 2009-07-01 with total page 416 pages. Available in PDF, EPUB and Kindle. Book excerpt: For millennia, we lived in harmony with the Earth, taking only what we required to survive. But in just the past few centuries, we have used our powers to satisfy our obsession with consumption and new technology, without regard for the consequences. And in doing so, we have exploited our surroundings on an unprecedented scale. In this revised and updated edition of From Naked Ape to Superspecies, David Suzuki and Holly Dressel lucidly describe how we have evolved beyond our needs, trampling other species, believing that we can make the Earth work the way we want it to. And they introduce us to the people who are fighting back, those who are resisting the inexorable advance of the "global economy" juggernaut, the people whose voices are difficult to hear over the din of corporate public relations machines. We learn about how human arrogance—demonstrated by our disregard for the small and microscopic species that constitute the Earth’s engine and our reckless use of technological inventions like powerful herbicides or genetically engineered crops—is threatening the health of our children and the safety of our food supply.
Book Synopsis Ladies of the Night by : Gene Simmons
Download or read book Ladies of the Night written by Gene Simmons and published by Phoenix Books. This book was released on 2008 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gene Simmons mega-rock star, businessman, marketing genius and self-proclaimed free spirit follows up his best-selling books Kiss And Make-Up and Sex Money Kiss with Ladies of the Night, an examination of the history of prostitution. Simmons makes the case that men have been stepping out on women since the beginning of time, and that the practice is not about to stop. For that reason alone, Simmons argues that prostitution should be legalized. He argues that prostitution is a victimless crime that could be made safe and become a large source of tax revenues. Simmons, who has never used a lady of the night, believes no one should have to pay for sex, whether it is through prostitutes or marriage. Regardless of where you stand on the issue, Simmons' book is an arresting, informative, humorous and outrageous exploration of the world's oldest profession, drawing on human nature, history, science and public policy.
Book Synopsis Relational Communication by : L. Edna Rogers
Download or read book Relational Communication written by L. Edna Rogers and published by Routledge. This book was released on 2014-03-05 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: Relational Communication: An Interactional Perspective to the Study of Process and Form brings together in one volume a full treatment of the relational communication perspective on the study of relationships. This perspective takes to heart the formative nature of communication by focusing on the codefined patterns of interaction by which members jointly create their relationship. This book provides a strong theoretical foundation to the research approach and also offers a step-by-step guide for carrying out the research procedures. It is a complete guide for the beginner or experienced researcher. The contributed chapters are written by researchers from psychology, clinical psychology, marital and family therapy, as well as marital, health, and organizational communication. Several of the studies on marital interaction are based on both American and Spanish research samples, offering a cross-disciplinary and cross-cultural application of the perspective. Part I opens with a discussion of the theoretical foundation and epistemological grounding of the perspective and then moves on to the observational research methods involved in applying the perspective's interactional approach. Part II presents a set of programmatic research exemplars that describe the application of the relational communication approach in different relational contexts, from marital to organizational settings. Part III offers a reflective overview of the research perspective. This book is appropriate for advanced undergraduate and graduate students, scholars, and researchers in communication. It will also be of interest to professionals, students, teachers and researchers in the fields of marital relations and family study, social and clinical psychology, family therapy, social work, and marital and family counseling programs.
Book Synopsis Fumbling the Future by : Robert C. Alexander
Download or read book Fumbling the Future written by Robert C. Alexander and published by iUniverse. This book was released on 1999-06-01 with total page 278 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ask consumers and users what names they associate with the multibillion dollar personal computer market, and they will answer IBM, Apple, Tandy, or Lotus. The more knowledgable of them will add the likes of Microsoft, Ashton-Tate, Compaq, and Borland. But no one will say Xerox. Fifteen years after it invented personal computing, Xerox still means "copy." Fumbling the Future tells how one of America's leading corporations invented the technology for one of the fastest-growing products of recent times, then miscalculated and mishandled the opportunity to fully exploit it. It is a classic story of how innovation can fare within large corporate structures, the real-life odyssey of what can happen to an idea as it travels from inspiration to implementation. More than anything, Fumbling the Future is a tale of human beings whose talents, hopes, fears, habits, and prejudices determine the fate of our largest organizations and of our best ideas. In an era in which technological creativity and economic change are so critical to the competitiveness of the American economy, Fumbling the Future is a parable for our times.

Book Synopsis Edsger Wybe Dijkstra by : Krzysztof R. Apt
Download or read book Edsger Wybe Dijkstra written by Krzysztof R. Apt and published by Morgan & Claypool. This book was released on 2022-07-14 with total page 576 pages. Available in PDF, EPUB and Kindle. Book excerpt: Edsger Wybe Dijkstra (1930–2002) was one of the most influential researchers in the history of computer science, making fundamental contributions to both the theory and practice of computing. Early in his career, he proposed the single-source shortest path algorithm, now commonly referred to as Dijkstra’s algorithm. He wrote (with Jaap Zonneveld) the first ALGOL 60 compiler, and designed and implemented with his colleagues the influential THE operating system. Dijkstra invented the field of concurrent algorithms, with concepts such as mutual exclusion, deadlock detection, and synchronization. A prolific writer and forceful proponent of the concept of structured programming, he convincingly argued against the use of the Go To statement. In 1972 he was awarded the ACM Turing Award for “fundamental contributions to programming as a high, intellectual challenge; for eloquent insistence and practical demonstration that programs should be composed correctly, not just debugged into correctness; for illuminating perception of problems at the foundations of program design.” Subsequently he invented the concept of self-stabilization relevant to fault-tolerant computing. He also devised an elegant language for nondeterministic programming and its weakest precondition semantics, featured in his influential 1976 book A Discipline of Programming in which he advocated the development of programs in concert with their correctness proofs. In the later stages of his life, he devoted much attention to the development and presentation of mathematical proofs, providing further support to his long-held view that the programming process should be viewed as a mathematical activity. In this unique new book, 31 computer scientists, including five recipients of the Turing Award, present and discuss Dijkstra’s numerous contributions to computing science and assess their impact. Several authors knew Dijkstra as a friend, teacher, lecturer, or colleague. Their biographical essays and tributes provide a fascinating multi-author picture of Dijkstra, from the early days of his career up to the end of his life.
