Science Of Software Product Lines

de Don Batory

~~42,22€~~ 38,00€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 This text is about compositional programming, where programs are constructed by composing prewritten software building blocks. Three modern compositional paradigms are covered, listed in order of decreasing emphasis:A Software Product Line is a design for a family of programs. Each program is composed from predefined increments of program functionality. The Linux Kernel is the largest known product line whose family size exceeds 102000 distinct programs.Model Driven Engineering is a general-purpose engineering methodology to support system design, analysis, construction, and evolution. Software designs are expressed as models. Transformations are composed to convert models into other models for analysis, to produce documentation and/or source.Streaming Applications are dataflow graphs whose nodes (called boxes) are computations with input and output data streams; boxes are wired/composed together to produce a custom program (aka software circuit). Examples are Unix pipe-and-filters and distributed stream processing.The book is aimed at both practitioners and advanced students, assuming some familiarity with programming in Java. It draws on the author’s unique personal insights from over four decades of experience as an academic at a leading research university as well as a hands-on developer of software tools. Written in an engaging style, the text highlights important contributions toward principled software engineering and composable designs made by researchers in diverse areas such as formal methods, programming languages, software system development, testing and deployment, databases, and networks. Parts of the book can be read and enjoyed as a historical narrative, while others can be studied more deeply to reflect on open research challenges and opportunities. In a world where AI and machine learning offer seductive yet untapped opportunities to generate software automatically, this book is a reminder of how and why the mathematical foundations of software construction still matter.

Formal Verification Of Just-In-Time Compilation

de Aurèle Barrière

~~58,25€~~ 52,43€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 This book outlines a methodology to develop formally verified Just-in-Time compilers. Just-in-Time compilation is a technique to execute programs, where execution is interleaved with optimizations of the program itself. These compilers often produce fast executions, so much so that their use has grown greatly for dynamic programming languages. Most modern web browsers today use Just-in-Time compilation to speed up the execution of the JavaScript programs they execute.However, the techniques used in Just-in-Time compilers can be particularly complex. This complexity can be a source of bugs and vulnerabilities. How can you make sure that your Just-in-Time compiler is bug-free? For traditional ahead-of-time compilers, many techniques have been developed to prevent compilation bugs. One such technique is formally verified compilation, where the compiler itself comes with proof that the semantics of the compiled program correspond to the semantics of the source program. But Just-in-Time compilers are more recent, less understood, and have been the target of far fewer verification efforts.To bring formal verification to Just-in-Time compilation, the book identifies a set of specific verification challenges and presents novel solutions for each of them. Such challenges include dynamic optimizations, speculative optimizations, deoptimizations, and the interleaving of interpretation and machine code generation. The author repurposes proof techniques from formally verified ahead-of-time compilers like CompCert. Following this methodology, readers can develop Just-in-Time compilers and formally prove that they behave as prescribed by the semantics of the program they execute. All proofs within the book have been mechanized in the Coq proof assistant.

Seymour Cray Era Of Supercomputers - From Fast Machines To Fast Codes

de Boelie Elzen e Donald Mackenzie

~~38,68€~~ 34,81€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 This book describes the development and use of supercomputers in the period 1960-1996, a time that can be called the Seymour Cray Era. For more than three decades, Cray’s computer designs were seen as the yardstick against which all other efforts were measured. Initially, this yardstick was sheer computing speed. However, the supercomputer world gradually became more complex and other factors became equally important.The initial development of supercomputers was commissioned and financed by the Los Alamos and Lawrence Livermore National Laboratories, which had huge computational needs in connection with nuclear weapons development. The computers designed by Cray satisfied those needs, while these computers were also sold to a few dozen other big research organizations and weather agencies. From the 1980s, a variety of companies started to compete with the Cray designs by offering supercomputers that used a new architectural approach, MPP: massively parallel processing. This new architecture, based on using tens of thousands of relatively simple microprocessors, subsequently began to dominate high-performance computing and marked the end of the Seymour Cray Era.This book is important reading for anyone working in the area of high-performance computing, providing essential historical context for the work of a legendary pioneer and the computers he became famous for designing. It will also be valuable to students of computing history and, more generally, to readers interested in the history of science and technology. For advanced students, the book illustrates how innovation in its very essence is a socio-technical process: not just a matter of developing the "best technology," but also of making appropriate choices concerning the interaction of human and technical factors in product design.

Indistinguishability Obfuscation From Well-Studied Assumptions

de Aayush Jain

~~58,25€~~ 52,43€ 10% IMEDIATO

DISPONIBILIDADE IMEDIATA

 Software obfuscation is used in cryptography to transform source code to make it unintelligible without altering what it computes. As a software security mechanism, it is essential that software obfuscation have a firm mathematical foundation.The research described in this book, for which the author won the ACM Dissertation Award, establishes the feasibility of mathematically rigorous software obfuscation from well-studied hardness conjectures. The mathematical object that the author constructs, indistinguishability obfuscation, is considered a theoretical "master tool" in the context of cryptography: not only in helping to achieve long-desired cryptographic goals such as functional encryption, but also in expanding the scope of the field of cryptography itself. For example, indistinguishability obfuscation aids in goals related to software security that were previously entirely in the domain of software engineering.

DISPONIBILIDADE IMEDIATA

 In the last decade, deep learning and word embeddings have made significant impacts on information retrieval (IR) by adding techniques based in neural networks and language models. At the same time, certain search modalities such as neural IR and conversational search have become more popular. This book, written by international academic and industry experts, brings the field up to date with detailed discussions of these new approaches and techniques. The book is organized in three sections: Foundations, Adaptations and Concerns, and Verticals.Under Foundations, we address topics that form the basic structure of any modern IR system, including recommender systems. These new techniques are developed to augment indexing, retrieval, and ranking. Neural IR, recommender systems, evaluation, query-driven functionality, and knowledge graphs are covered in this section.IR systems need to adapt to specific user characteristics and preferences, and techniques that were considered too niche a few years ago are now a matter of system design consideration. The Adaptations and Concerns section covers the following topics: conversational search, cross-language retrieval, temporal extraction and retrieval, bias in retrieval systems, and privacy in search.While web search engines are the most popular information access point, there are cases where specific verticals provide a better experience in terms of content and relevance. The Verticals section describes eCommerce, professional search, personal collections, music retrieval, and biomedicine as examples.

DISPONIBILIDADE IMEDIATA

 There are significant financial and legal implications for ensuring design correctness and safety in autonomous systems. This book introduces new verification and synthesis algorithms to provide certifiable trusts for real-world autonomous systems. On the theoretical front, the techniques are armed with soundness, precision, and relative completeness guarantees. On the experimental side, this book shows that techniques can be successfully applied on a sequence of real-world problems, including a suite of Toyota engine control modules verified for the first time, satellite control systems, and autonomous driving and ADAS-based maneuvers.Insights throughout the book provide a level of assurance that can be provided by formal methods for today’s autonomous systems. Verification and synthesis for typical models of real-world autonomous systems are challenging due to their high dimensionality, nonlinearities, and nondeterministic and hybrid nature. In addressing these challenges, several chapters present data-driven algorithmic verification via reachability analysis of complex hybrid systems as well as controller synthesis for dynamic systems under disturbance.The book includes the first algorithm for over-approximating reach sets of general nonlinear models with locally optimal tightness guarantees as well as algorithms to find correct-by-construction controllers for nonlinear dynamical systems. It is written for researchers in the corporate world, academia, government, and practitioners in autonomous systems.

de Manish Raghavan

63,55€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book demonstrates the need for and the value of interdisciplinary research in addressing important societal challenges associated with the widespread use of algorithmic decision-making. Algorithms are increasingly being used to make decisions in various domains such as criminal justice, medicine, and employment. While algorithmic tools have the potential to make decision-making more accurate, consistent, and transparent, they pose serious challenges to societal interests. For example, they can perpetuate discrimination, cause representational harm, and deny opportunities.The Societal Impacts of Algorithmic Decision-Making presents several contributions to the growing body of literature that seeks to respond to these challenges, drawing on techniques and insights from computer science, economics, and law. The author develops tools and frameworks to characterize the impacts of decision-making and incorporates models of behavior to reason about decision-making in complex environments. These technical insights are leveraged to deepen the qualitative understanding of the impacts of algorithms on problem domains including employment and lending.The social harms of algorithmic decision-making are far from being solved. While easy solutions are not presented here, there are actionable insights for those who seek to deploy algorithms responsibly. The research presented within this book will hopefully contribute to broader efforts to safeguard societal values while still taking advantage of the promise of algorithmic decision-making.

On Monotonicity Testing And The 2-To-2 Games Conjecture

de Dor Minzer

50,20€ + 10% EM CARTÃO

DISPONIBILIDADE IMEDIATA

 This book discusses two questions in Complexity Theory: the Monotonicity Testing problem and the 2-to-2 Games Conjecture.Monotonicity testing is a problem from the field of property testing, first considered by Goldreich et al. in 2000. The input of the algorithm is a function, and the goal is to design a tester that makes as few queries to the function as possible, accepts monotone functions and rejects far-from monotone functions with a probability close to 1.The first result of this book is an essentially optimal algorithm for this problem. The analysis of the algorithm heavily relies on a novel, directed, and robust analogue of a Boolean isoperimetric inequality of Talagrand from 1993.The probabilistically checkable proofs (PCP) theorem is one of the cornerstones of modern theoretical computer science. One area in which PCPs are essential is the area of hardness of approximation. Therein, the goal is to prove that some optimization problems are hard to solve, even approximately. Many hardness of approximation results were proved using the PCP theorem; however, for some problems optimal results were not obtained. This book touches on some of these problems, and in particular the 2-to-2 games problem and the vertex cover problem.The second result of this book is a proof of the 2-to-2 games conjecture (with imperfect completeness), which implies new hardness of approximation results for problems such as vertex cover and independent set. It also serves as strong evidence towards the unique games conjecture, a notorious related open problem in theoretical computer science. At the core of the proof is a characterization of small sets of vertices in Grassmann graphs whose edge expansion is bounded away from 1.

Ever since, diverse prophecies of computing have continually emerged, through to the present day.As computing spread beyond the US and UK, such prophecies emerged from strikingly different economic, political, and cultural conditions. This volume explores how these expectations differed, assesses unexpected commonalities, and suggests ways to understand the divergences and convergences.This book examines thirteen countries, based on source material in ten different languages—the effort of an international team of scholars. In addition to analyses of debates, political changes, and popular speculations, we also show a wide range of pictorial representations of "the future with computers."

 Set theory, logic, discrete mathematics, and fundamental algorithms (along with their correctness and complexity analysis) will always remain useful for computing professionals and need to be understood by students who want to succeed. This textbook explains a number of those fundamental algorithms to programming students in a concise, yet precise, manner. The book includes the background material needed to understand the explanations and to develop such explanations for other algorithms. The author demonstrates that clarity and simplicity are achieved not by avoiding formalism, but by using it properly.The book is self-contained, assuming only a background in high school mathematics and elementary program writing skills. It does not assume familiarity with any specific programming language. Starting with basic concepts of sets, functions, relations, logic, and proof techniques including induction, the necessary mathematical framework for reasoning about the correctness, termination and efficiency of programs is introduced with examples at each stage. The book contains the systematic development, from appropriate theories, of a variety of fundamental algorithms related to search, sorting, matching, graph-related problems, recursive programming methodology and dynamic programming techniques, culminating in parallel recursive structures.
