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.

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.

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.

Download or read book Working Effectively with Legacy Code written by Michael Feathers and published by Prentice Hall Professional. This book was released on 2004-09-22 with total page 457 pages. Available in PDF, EPUB and Kindle. Book excerpt: Get more out of your legacy systems: more performance, functionality, reliability, and manageability Is your code easy to change? Can you get nearly instantaneous feedback when you do change it? Do you understand it? If the answer to any of these questions is no, you have legacy code, and it is draining time and money away from your development efforts. In this book, Michael Feathers offers start-to-finish strategies for working more effectively with large, untested legacy code bases. This book draws on material Michael created for his renowned Object Mentor seminars: techniques Michael has used in mentoring to help hundreds of developers, technical managers, and testers bring their legacy systems under control. The topics covered include Understanding the mechanics of software change: adding features, fixing bugs, improving design, optimizing performance Getting legacy code into a test harness Writing tests that protect you against introducing new problems Techniques that can be used with any language or platform—with examples in Java, C++, C, and C# Accurately identifying where code changes need to be made Coping with legacy systems that aren't object-oriented Handling applications that don't seem to have any structure This book also includes a catalog of twenty-four dependency-breaking techniques that help you work with program elements in isolation and make safer changes.

Download or read book Believe in People written by Charles Koch and published by St. Martin's Press. This book was released on 2020-11-17 with total page 272 pages. Available in PDF, EPUB and Kindle. Book excerpt: A surprising take on how you can help tackle the really big problems in society–from one of America’s most successful entrepreneurs. People are looking for a better way. Towering barriers are holding millions of people back, and the institutions that should help everyone rise are not doing the job. Crumbling communities. One-size fits all education. Businesses that rig the economy. Public policy that stifles opportunity and emboldens the extremes. As a result, this country is quickly heading toward a two-tiered society. Today’s challenges call for nothing short of a paradigm shift – away from a top-down approach that sees people as problems to be managed, toward bottom-up solutions that empower everyone to realize their potential and foster a more inclusive society. Such a shift starts by asking: What would it mean to truly believe in people? Businessman and philanthropist Charles Koch has devoted his life to answering that question. Learn what he’s discovered during his 60-year career to help you apply the principles of empowerment in your life, in your business, and in society. By learning from the social movements and applying the principles that have enabled social progress throughout history, Koch has achieved more than he dreamed possible – building one of the world’s most successful companies and founding Stand Together, one of America’s most innovative philanthropic communities. Stand Together CEO Brian Hooks and Koch show how the only way to solve the really big problems – from poverty and addiction to harmful business practices and destructive public policy – is for each and every one of us to find and take action in our unique role as part of the solution. Full of compelling examples of what works – including several first-person accounts from individuals whose lives have been transformed – Koch and Hooks’ refreshing approach promotes partnership instead of partisanship and speaks to people from different perspectives and all walks of life. They show that no injustice is too tough to overcome if you share a deep belief in people, are willing to unite with anyone to do right, and work to empower others from the bottom up.

Download or read book Discourses and Selected Writings written by Epictetus and published by Penguin UK. This book was released on 2008-08-28 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contains The Discourses/Fragments/Enchiridion 'I must die. But must I die bawling?' Epictetus, a Greek Stoic and freed slave, ran a thriving philosophy school in Nicopolis in the early second century AD. His animated discussions were celebrated for their rhetorical wizardry and were written down by Arrian, his most famous pupil. The Discourses argue that happiness lies in learning to perceive exactly what is in our power to change and what is not, and in embracing our fate to live in harmony with god and nature. In this personal, practical guide to the ethics of Stoicism and moral self-improvement, Epictetus tackles questions of freedom and imprisonment, illness and fear, family, friendship and love. Translated and Edited with an Introduction by Robert Dobbin

Download or read book Start with Why written by Simon Sinek and published by Penguin. This book was released on 2011-12-27 with total page 257 pages. Available in PDF, EPUB and Kindle. Book excerpt: The inspirational bestseller that ignited a movement and asked us to find our WHY Discover the book that is captivating millions on TikTok and that served as the basis for one of the most popular TED Talks of all time—with more than 56 million views and counting. Over a decade ago, Simon Sinek started a movement that inspired millions to demand purpose at work, to ask what was the WHY of their organization. Since then, millions have been touched by the power of his ideas, and these ideas remain as relevant and timely as ever. START WITH WHY asks (and answers) the questions: why are some people and organizations more innovative, more influential, and more profitable than others? Why do some command greater loyalty from customers and employees alike? Even among the successful, why are so few able to repeat their success over and over? People like Martin Luther King Jr., Steve Jobs, and the Wright Brothers had little in common, but they all started with WHY. They realized that people won't truly buy into a product, service, movement, or idea until they understand the WHY behind it. START WITH WHY shows that the leaders who have had the greatest influence in the world all think, act and communicate the same way—and it's the opposite of what everyone else does. Sinek calls this powerful idea The Golden Circle, and it provides a framework upon which organizations can be built, movements can be led, and people can be inspired. And it all starts with WHY.

Download or read book Principles of Abstract Interpretation written by Patrick Cousot and published by MIT Press. This book was released on 2021-09-21 with total page 833 pages. Available in PDF, EPUB and Kindle. Book excerpt: Introduction to abstract interpretation, with examples of applications to the semantics, specification, verification, and static analysis of computer programs. Formal methods are mathematically rigorous techniques for the specification, development, manipulation, and verification of safe, robust, and secure software and hardware systems. Abstract interpretation is a unifying theory of formal methods that proposes a general methodology for proving the correctness of computing systems, based on their semantics. The concepts of abstract interpretation underlie such software tools as compilers, type systems, and security protocol analyzers. This book provides an introduction to the theory and practice of abstract interpretation, offering examples of applications to semantics, specification, verification, and static analysis of programming languages with emphasis on calculational design. The book covers all necessary computer science and mathematical concepts--including most of the logic, order, linear, fixpoint, and discrete mathematics frequently used in computer science--in separate chapters before they are used in the text. Each chapter offers exercises and selected solutions. Chapter topics include syntax, parsing, trace semantics, properties and their abstraction, fixpoints and their abstractions, reachability semantics, abstract domain and abstract interpreter, specification and verification, effective fixpoint approximation, relational static analysis, and symbolic static analysis. The main applications covered include program semantics, program specification and verification, program dynamic and static analysis of numerical properties and of such symbolic properties as dataflow analysis, software model checking, pointer analysis, dependency, and typing (both for forward and backward analysis), and their combinations. Principles of Abstract Interpretation is suitable for classroom use at the graduate level and as a reference for researchers and practitioners.

Download or read book Constructivity and Computability in Historical and Philosophical Perspective written by Jacques Dubucs and published by Springer. This book was released on 2014-08-27 with total page 223 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ranging from Alan Turing’s seminal 1936 paper to the latest work on Kolmogorov complexity and linear logic, this comprehensive new work clarifies the relationship between computability on the one hand and constructivity on the other. The authors argue that even though constructivists have largely shed Brouwer’s solipsistic attitude to logic, there remain points of disagreement to this day. Focusing on the growing pains computability experienced as it was forced to address the demands of rapidly expanding applications, the content maps the developments following Turing’s ground-breaking linkage of computation and the machine, the resulting birth of complexity theory, the innovations of Kolmogorov complexity and resolving the dissonances between proof theoretical semantics and canonical proof feasibility. Finally, it explores one of the most fundamental questions concerning the interface between constructivity and computability: whether the theory of recursive functions is needed for a rigorous development of constructive mathematics. This volume contributes to the unity of science by overcoming disunities rather than offering an overarching framework. It posits that computability’s adoption of a classical, ontological point of view kept these imperatives separated. In studying the relationship between the two, it is a vital step forward in overcoming the disagreements and misunderstandings which stand in the way of a unifying view of logic.
