-Titulo Original : Peopleware Productive Projects And Teams-Fabricante : Addison-Wesley Professional-Descripcion Original: Few books in computing have had as profound an influence on software management as Peopleware. The unique insight of this longtime best seller is that the major issues of software development are human, not technical. They’re not easy issues; but solve them, and you’ll maximize your chances of success. “Peopleware has long been one of my two favorite books on software engineering. Its underlying strength is its base of immense real experience, much of it quantified. Many, many varied projects have been reflected on and distilled; but what we are given is not just lifeless distillate, but vivid examples from which we share the authors’ inductions. Their premise is right: most software project problems are sociological, not technological. The insights on team jelling and work environment have changed my thinking and teaching. The third edition adds strength to strength.” Frederick P. Brooks, Jr., Kenan Professor of Computer Science, University of North Carolina at Chapel Hill, Author of The Mythical Man-Month and The Design of Design“Peopleware is the one book that everyone who runs a software team needs to read and reread once a year. In the quarter century since the first edition appeared, it has become more important, not less, to think about the social and human issues in software develop¿ment. This is the only way we’re going to make more humane, productive workplaces. Buy it, read it, and keep a stock on hand in the office supply closet.” Joel Spolsky, Co-founder, Stack Overflow“When a book about a field as volatile as software design and use extends to a third edition, you can be sure that the authors write of deep principle, of the fundamental causes for what we readers experience, and not of the surface that everyone recognizes. And to bring people, actual human beings, into the mix! How excellent. How rare. The authors have made this third edition, with its additions, entirely terrific.” Lee Devin and Rob Austin, Co-authors of The Soul of Design and Artful Making For this third edition, the authors have added six new chapters and updated the text throughout, bringing it in line with today’s development environments and challenges. For example, the book now discusses pathologies of leadership that hadn’t previously been judged to be pathological; an evolving culture of meetings; hybrid teams made up of people from seemingly incompatible generations; and a growing awareness that some of our most common tools are more like anchors than propellers. Anyone who needs to manage a software project or software organization will find invaluable advice throughout the book.

-Titulo Original : Sysml Distilled A Brief Guide To The Systems Modeling Language-Fabricante : Addison-Wesley Professional-Descripcion Original: The Systems Modeling Language (SysML) extends UML with powerful systems engineering capabilities for modeling a wider spectrum of systems and capturing all aspects of a system’s design. SysML Distilled is the first clear, concise guide for everyone who wants to start creating effective SysML models. (Drawing on his pioneering experience at Lockheed Martin and NASA, Lenny Delligatti illuminates SysML’s core components and provides practical advice to help you create good models and good designs. Delligatti begins with an easy-to-understand overview of Model-Based Systems Engineering (MBSE) and an explanation of how SysML enables effective system specification, analysis, design, optimization, verification, and validation. Next, he shows how to use all nine types of SysML diagrams, even if you have no previous experience with modeling languages. A case study running through the text demonstrates the use of SysML in modeling a complex, real-world sociotechnical system. Modeled after Martin Fowler’s classic UML Distilled, Delligatti’s indispensable guide quickly teaches you what you need to know to get started and helps you deepen your knowledge incrementally as the need arises. Like SysML itself, the book is method independent and is designed to support whatever processes, procedures, and tools you already use. Coverage Includes Why SysML was created and the business case for using it Quickly putting SysML to practical use What to know before you start a SysML modeling project Essential concepts that apply to all SysML diagrams SysML diagram elements and relationships Diagramming block definitions, internal structures, use cases, activities, interactions, state machines, constraints, requirements, and packages Using allocations to define mappings among elements across a model SysML notation tables, version changes, and sources for more information Review “In keeping with the outstanding tradition of Addison-Wesley’s technical publications, Lenny Delligatti’s SysML Distilled does not disappoint. Lenny has done a masterful job of capturing the spirit of OMG SysML as a practical, standards-based modeling language to help systems engineers address growing system complexity. This book is loaded with matter-of-fact insights, starting with basic MBSE concepts to distinguishing the subtle differences between use cases and scenarios to illumination on namespaces and SysML packages, and even speaks to some of the more esoteric SysML semantics such as token flows.” -Jeff Estefan, Principal Engineer, NASA’s Jet Propulsion Laboratory “The power of a modeling language, such as SysML, is that it facilitates communication not only within systems engineering but across disciplines and across the development life cycle. Many languages have the potential to increase communication, but without an effective guide, they can fall short of that objective. In SysML Distilled, Lenny Delligatti combines just the right amount of technology with a common-sense approach to utilizing SysML toward achieving that communication. Having worked in systems and software engineering across many domains for the last 30 years, and having taught computer languages, UML, and SysML to many organizations and within the college setting, I find Lenny’s book an invaluable resource. He presents the concepts clearly and provides useful and pragmatic examples to get you off the ground quickly and enables you to be an effective modeler.” -Thomas W. Fargnoli, Lead Member of the Engineering Staff, Lockheed Martin “This book provides an excellent introduction to SysML. Lenny Delligatti’s explanations are concise and easy to understand; the examples well thought out and interesting.” -Susanne Sherba, Senior Lecturer, Department of Computer Science, University of Denver “Lenny hits the thin line between a reference book for SysML to look up elements and an entertaining book that could be read in its entirety to learn the language.

-Titulo Original : Concrete Mathematics A Foundation For Computer Science (2nd Edition)-Fabricante : Addison-Wesley Professional-Descripcion Original: This book introduces the mathematics that supports advanced computer programming and the analysis of algorithms. The primary aim of its well-known authors is to provide a solid and relevant base of mathematical skills - the skills needed to solve complex problems, to evaluate horrendous sums, and to discover subtle patterns in data. It is an indispensable text and reference not only for computer scientists - the authors themselves rely heavily on it! - but for serious users of mathematics in virtually every discipline. Concrete Mathematics is a blending of CONtinuous and disCRETE mathematics. More concretely, the authors explain, it is the controlled manipulation of mathematical formulas, using a collection of techniques for solving problems. The subject matter is primarily an expansion of the Mathematical Preliminaries section in Knuths classic Art of Computer Programming, but the style of presentation is more leisurely, and individual topics are covered more deeply. Several new topics have been added, and the most significant ideas have been traced to their historical roots. The book includes more than 500 exercises, divided into six categories. Complete answers are provided for all exercises, except research problems, making the book particularly valuable for self-study. Major topics include: Sums Recurrences Integer functions Elementary number theory Binomial coefficients Generating functions Discrete probability Asymptotic methods This second edition includes important new material about mechanical summation. In response to the widespread use of the first edition as a reference book, the bibliography and index have also been expanded, and additional nontrivial improvements can be found on almost every page. Readers will appreciate the informal style of Concrete Mathematics. Particularly enjoyable are the marginal graffiti contributed by students who have taken courses based on this material. The authors want to convey not only the importance of the techniques presented, but some of the fun in learning and using them.

-Titulo Original : Modern C Design Generic Programming And Design Patterns Applied-Fabricante : Addison-Wesley Professional-Descripcion Original: In Modern C Design, Andrei Alexandrescu opens new vistas for C programmers. Displaying extraordinary creativity and programming virtuosity, Alexandrescu offers a cutting-edge approach to design that unites design patterns, generic programming, and C, enabling programmers to achieve expressive, flexible, and highly reusable code. This book introduces the concept of generic components reusable design templates that produce boilerplate code for compiler consumption all within C. Generic components enable an easier and more seamless transition from design to application code, generate code that better expresses the original design intention, and support the reuse of design structures with minimal recoding. The author describes the specific C techniques and features that are used in building generic components and goes on to implement industrial strength generic components for real-world applications. Recurring issues that C developers face in their day-to-day activity are discussed in depth and implemented in a generic way. These include: Policy-based design for flexibility Partial template specialization Typelists powerful type manipulation structures Patterns such as Visitor, Singleton, Command, and Factories Multi-method engines For each generic component, the book presents the fundamental problems and design options, and finally implements a generic solution. From the Inside Flap You might be holding this book in a bookstore, asking yourself whether you should buy it. Or maybe you are in your employers library, wondering whether you should invest time in reading it. I know you dont have time, so Ill cut to the chase. If you have ever asked yourself how to write higher-level programs in C, how to cope with the avalanche of irrelevant details that plague even the cleanest design, or how to build reusable components that you dont have to hack into each time you take them to your next application, then this book is for you. Imagine the following scenario. You come from a design meeting with a couple of printed diagrams, scribbled with your annotations. Okay, the event type passed between these objects is not char anymore; its int. You change one line of code. The smart pointers to Widget are too slow; they should go unchecked. You change one line of code. The object factory needs to support the new Gadget class just added by another department. You change one line of code. You changed the design. Compile. Link. Done. Well, there is something wrong with this scenario, isnt there? A much more likely scenario is this: You come from the meeting in a hurry because you have a pile of work to do. You fire a global search. You perform surgery on code. You add code. You introduce bugs. You remove the bugs . . . thats the way a programmers job is, right? Although this book cannot possibly promise you the first scenario, it is nonetheless a resolute step in that direction. It tries to present C as a newly discovered language for software architects. Traditionally, code is the most detailed and intricate aspect of a software system. Historically, in spite of various levels of language support for design methodologies (such as object orientation), a significant gap persisted between the blueprints of a program and its code because the code must take care of the ultimate details of the implementation and of many ancillary tasks. The intent of the design is, more often than not, dissolved in a sea of quirks. This book presents a collection of reusable design artifacts, called generic components, together with the techniques that make them possible. These generic components bring their users the well-known benefits of libraries, but in the broader space of system architecture. The coding techniques and the implementations provided focus on tasks and issues that traditionally fall in the area of design, activities usually done before coding. Because of their high level, ge...

-Titulo Original : Accelerated C Practical Programming By Example-Fabricante : Addison-Wesley Professional-Descripcion Original: This is a first-rate introductory book that takes a practical approach to solving problems using C. It covers a much wider scope of C programming than other introductory books Ive seen, and in a surprisingly compact format. - Dag Bruck, founding member of the ANSI/ISO C committee The authors present a clear, cogent introduction to C programming in a way that gets the student writing nontrivial programs immediately. - Stephen Clamage, Sun Microsystems, Inc., and chair of the ANSI C committee Anyone reading just this one book and working through the examples and exercises will have the same skills as many professional programmers. - Jeffrey D. Oldham, Stanford University Why is Accelerated C so effective? Because it: *Starts with the most useful concepts rather than the most primitive ones: You can begin writing programs immediately. *Describes real problems and solutions, not just language features: You see not only what each feature is, but also how to use it. * Covers the language and standard library together: You can use the library right from the start. The authors proved this approach in their professional-education course at Stanford University, where student Review If you dont have a lot of time, but still want to learn the latest in C, you dont have to learn C first. You might learn more by digging into current language features and classes from the very beginning. Thats the approach thats offered by Accelerated C, a text that delves into more advanced C features like templates and Standard Template Library (STL) collection classes early on. This book arguably can get a motivated beginning programmer into C more quickly than other available tutorials. What separates this title from the rest of the pack is that it jumps right in with samples that take advantage of the Standard C of today--from streams to built-in container classes, such as vectors and linked lists. Early examples are more complex than in other books, but the thoroughness and relaxed pace of the explanations will bring the novice up to speed. (Although it ships at a slender 350 pages, Accelerated C is packed with samples, tips, and example problems; about 10 per chapter.) After a tour of basic C, the book looks at more advanced C features, such as templates, including built-in support for containers. Besides tapping the strength of Standard C, you also will learn to design with your own templates. (Other tutorials would defer this material until later on.) The authors have tested the approach in the book in their own teaching, and honed a set of worthwhile examples that will help anyone get familiar with these powerful language features. All examples make use of the command line and console (without GUI programs), but the advantage is that this code should run on any of todays operating systems and compilers. Later sections cover the basics of class design, which include good coverage of operator overloading and inheritance. With its innovative approach to teaching the language, Accelerated C will challenge readers in the right way. It suggests that you dont need to learn C to be productive in C. Written in an approachable style, it deserves a close look from any C novice. --Richard Dragan Topics covered: Introduction to C Console I/O with stream classes Basic string handling Loop and flow-control statements Arrays Using functions and methods Using Standard Template Library (STL) containers (vectors, linked lists, and maps) Iterators Sorting and generic functions Basic class design Pointers and arrays File I/O Memory-management techniques, including statically and dynamically allocated memory Adding stream support to custom classes Conversion operators Operator overloading Friend functions Inheritance Polymorphism and virtual functions Handle idioms for classes, including reference counting Quick reference to the C language Fro...

-Titulo Original : Deep Learning Illustrated A Visual, Interactive Guide To Artificial Intelligence (addison-wesley Data & Analytics Series)-Fabricante : Addison-Wesley Professional-Descripcion Original: Deep learning is one of today’s hottest fields. This approach to machine learning is achieving breakthrough results in some of today’s highest profile applications, in organizations ranging from Google to Tesla, to Apple. Thousands of technical professionals and students want to start leveraging its power, but previous books on deep learning have often been non-intuitive, inaccessible, and dry. In Deep Learning Illustrated, three world-class instructors and practitioners present a uniquely visual, intuitive, and accessible high-level introduction to the techniques and applications of deep learning. Packed with vibrant, full-color illustrations, it abstracts away much of the complexity of building deep learning models, making the field more fun to learn, and accessible to a far wider audience. Part I’s high-level overview explains what Deep Learning is, why it has become so ubiquitous, and how it relates to concepts and terminology such as Artificial Intelligence, Machine Learning, Artificial Neural Networks, and Reinforcement Learning. These opening chapters are replete with vivid illustrations, easy-to-grasp analogies, and character-focused narratives. Building on this foundation, the authors then offer a practical reference and tutorial for applying a wide spectrum of proven deep learning techniques. Essential theory is covered with as little mathematics as possible, and illuminated with hands-on Python code. Theory is supported with practical “run-throughs” available in accompanying Jupyter notebooks, delivering a pragmatic understanding of all major deep learning approaches and their applications: machine vision, natural language processing, image generation, and videogaming. To help readers accomplish more in less time, the authors feature several of today’s most widely-used and innovative deep learning libraries, including TensorFlow and its high-level API, Keras; PyTorch, and the recently-released high-level Coach, a TensorFlow API that abstracts away the complexity typically associated with building Deep Reinforcement Learning algorithms.

-Titulo Original : Writing Effective Use Cases-Fabricante : Addison-Wesley Professional-Descripcion Original: Use cases have never been this easy to understand -- or this easy to create! In Writing Effective Use Cases, Alistair Cockburn offers a hands-on, soup-to-nuts guide to use case development, based on the proven concepts he has refined through years of research, development, and seminar presentations. Cockburn begins by answering the most basic questions facing anyone interested in use cases: What does a use case look like? When do I write one? Next, he introduces each key element of use cases: actors, stakeholders, design scope, goal levels, scenarios, and more. Writing Effective Use Cases contains detailed guidelines, formats, and project standards for creating use cases -- as well as a detailed chapter on style, containing specific dos and donts. Cockburn shows how use cases fit together with requirements gathering, business processing reengineering, and other key issues facing software professionals. The book includes practice exercises with solutions, as well as a detailed appendix on how to use these techniques with UML. For all application developers, object technology practitioners, software system designers, architects, and analysts. Review Alistair Cockburns Writing Effective Use Cases is an approachable, informative, and very intelligent treatment of an essential topic of software design. Use cases describe how actors interact with computer systems and are essential to software-modeling requirements. For anyone who designs software, this title offers some real insight into writing use cases that are clear and correct and lead to better and less costly software. The focus of this text is on use cases that are written, as opposed to modeled in UML. This book may change your mind about the advantages of writing step-by-step descriptions of the way users (or actors) interact with systems. Besides being an exceptionally clear writer, the author has plenty to say about what works and what doesnt when it comes to creating use cases. There are several standout bits of expertise on display here, including excellent techniques for finding the right scope for use cases. (The book uses a color scheme in which blue indicates a sea-level use case thats just right, while higher-level use cases are white, and overly detailed ones are indigo. Cockburn also provides notational symbols to document these levels of detail within a design.) This book contains numerous tips on the writing style for use cases and plenty of practical advice for managing projects that require a large number of use cases. One particular strength lies in the numerous actual use cases (many with impressive detail) that are borrowed from real-world projects, and demonstrate both good and bad practices. Even though the author expresses a preference for the format of use cases, he presents a variety of styles, including UML graphical versions. The explanation of how use cases fit into the rest of the software engineering process is especially good. The book concludes with several dozen concrete tips for writing better use cases. Software engineering books often get bogged down in theory. Not so in Writing Effective Use Cases, a slender volume with a practical focus, a concise presentation style, and something truly valuable to say. This book will benefit most anyone who designs software for a living. --Richard Dragan Topics covered: Introduction to use cases Requirements Usage narratives Actors and goals Stakeholders Graphical models for use cases Scope for use cases (enterprise-level through nuts-and-bolts use cases) Primary and supporting actors Goal levels: user goals, summary level, and subfunctions Preconditions, triggers, and guarantees Main success scenarios Extensions for describing failures Formats for use cases (including fully dressed one- and two-column formats) Use case templates for five common project types Managing use cases for large projects CRUD use cases Business-process...

-Titulo Original : Agile Software Requirements Lean Requirements Practices For Teams, Programs, And The Enterprise (agile Software Development Series)-Fabricante : Addison-Wesley Professional-Descripcion Original: “We need better approaches to understanding and managing software requirements, and Dean provides them in this book. He draws ideas from three very useful intellectual pools: classical management practices, Agile methods, and lean product development. By combining the strengths of these three approaches, he has produced something that works better than any one in isolation.” -From the Foreword by Don Reinertsen, President of Reinertsen & Associates; author of Managing the Design Factory; and leading expert on rapid product development Effective requirements discovery and analysis is a critical best practice for serious application development. Until now, however, requirements and Agile methods have rarely coexisted peacefully. For many enterprises considering Agile approaches, the absence of effective and scalable Agile requirements processes has been a showstopper for Agile adoption. In Agile Software Requirements, Dean Leffingwell shows exactly how to create effective requirements in Agile environments. Part I presents the “big picture” of Agile requirements in the enterprise, and describes an overall process model for Agile requirements at the project team, program, and portfolio levels Part II describes a simple and lightweight, yet comprehensive model that Agile project teams can use to manage requirements Part III shows how to develop Agile requirements for complex systems that require the cooperation of multiple teams Part IV guides enterprises in developing Agile requirements for ever-larger “systems of systems,” application suites, and product portfolios This book will help you leverage the benefits of Agile without sacrificing the value of effective requirements discovery and analysis. You’ll find proven solutions you can apply right now-whether you’re a software developer or tester, executive, project/program manager, architect, or team leader. Review Praise for Agile Software Requirements “In my opinion, there is no book out there that more artfully addresses the specific needs of agile teams, programs, and portfolios all in one. I believe this book is an organizational necessity for any enterprise.” -Sarah Edrie, Director of Quality Engineering, Harvard Business School “Agile Software Requirements and Mr. Leffingwell’s teachings have been very influential and inspiring to our organization. They have allowed us to make critical cultural changes to the way we approach software development by following the framework he’s outlined here. It has been an extraordinary experience.” -Chris Chapman, Software Development Manager, Discount Tire “This book supplies empirical wisdom connected with strong and very well-structured theory of succeeding with software projects of different scales. People new to agile, practitioners, or accomplished agilists-we all were waiting for such a book.” -Oleksandr (Alex) Yakyma, Agile Consultant, enter-Agile “This book presents practical and proven agile approaches for managing software requirements for a team, collaborating teams of teams, and all across the enterprise. However, this is not only a great book on agile requirements engineering; rather, Leffingwell describes the bigger picture of how the enterprise can achieve the benefits of business agility by implementing lean product development flow. His ‘Big Picture’ of agile requirements is an excellent reference for any organization pursuing an intrinsically lean software development operational mode. Best of all, we’ve applied many of these principles and practices at Nokia (and even helped create some of them), and therefore we know they work. -Juha-Markus Aalto, Agile Change Program Manager, Nokia Corporation “This pragmatic, easy-to-understand, yet thought-provoking book provides a hands-on guide to addressing a key problem that enterprises face: How to make requirements practices work effectively in large-scale agile environments.

-Titulo Original : Domain-driven Design Tackling Complexity In The Heart Of Software-Fabricante : Addison-Wesley Professional-Descripcion Original: From the Back Cover “Eric Evans has written a fantastic book on how you can make the design of your software match your mental model of the problem domain you are addressing. “His book is very compatible with XP. It is not about drawing pictures of a domain; it is about how you think of it, the language you use to talk about it, and how you organize your software to reflect your improving understanding of it. Eric thinks that learning about your problem domain is as likely to happen at the end of your project as at the beginning, and so refactoring is a big part of his technique. “The book is a fun read. Eric has lots of interesting stories, and he has a way with words. I see this book as essential reading for software developers it is a future classic.” Ralph Johnson, author of Design Patterns “If you don’t think you are getting value from your investment in object-oriented programming, this book will tell you what you’ve forgotten to do.“Eric Evans convincingly argues for the importance of domain modeling as the central focus of development and provides a solid framework and set of techniques for accomplishing it. This is timeless wisdom, and will hold up long after the methodologies du jour have gone out of fashion.” Dave Collins, author of Designing Object-Oriented User Interfaces “Eric weaves real-world experience modeling and building business applications into a practical, useful book. Written from the perspective of a trusted practitioner, Eric’s descriptions of ubiquitous language, the benefits of sharing models with users, object life-cycle management, logical and physical application structuring, and the process and results of deep refactoring are major contributions to our field.” Luke Hohmann, author of Beyond Software Architecture This book belongs on the shelf of every thoughtful software developer.--Kent BeckWhat Eric has managed to capture is a part of the design process that experienced object designers have always used, but that we have been singularly unsuccessful as a group in conveying to the rest of the industry. Weve given away bits and pieces of this knowledge...but weve never organized and systematized the principles of building domain logic. This book is important.--Kyle Brown, author of Enterprise Java™ Programming with IBM® WebSphere®The software development community widely acknowledges that domain modeling is central to software design. Through domain models, software developers are able to express rich functionality and translate it into a software implementation that truly serves the needs of its users. But despite its obvious importance, there are few practical resources that explain how to incorporate effective domain modeling into the software development process.Domain-Driven Design fills that need. This is not a book about specific technologies. It offers readers a systematic approach to domain-driven design, presenting an extensive set of design best practices, experience-based techniques, and fundamental principles that facilitate the development of software projects facing complex domains. Intertwining design and development practice, this book incorporates numerous examples based on actual projects to illustrate the application of domain-driven design to real-world software development.Readers learn how to use a domain model to make a complex development effort more focused and dynamic. A core of best practices and standard patterns provides a common language for the development team. A shift in emphasis--refactoring not just the code but the model underlying the code--in combination with the frequent iterations of Agile development leads to deeper insight into domains and enhanced communication between domain expert and programmer. Domain-Driven Design then builds on this foundation, and addresses modeling and design for complex systems and larger organizations.Specific topics covered include:Getting all team members to speak the same languageConnectin...

This ones a keeper.” --Robert C. Martin “If you want to be an expert in the state of the art in TDD, you need to understand the ideas in this book.”--Michael Feathers Test-Driven Development (TDD) is now an established technique for delivering better software faster. TDD is based on a simple idea: Write tests for your code before you write the code itself. However, this simple idea takes skill and judgment to do well. Now theres a practical guide to TDD that takes you beyond the basic concepts. Drawing on a decade of experience building real-world systems, two TDD pioneers show how to let tests guide your development and “grow” software that is coherent, reliable, and maintainable. Steve Freeman and Nat Pryce describe the processes they use, the design principles they strive to achieve, and some of the tools that help them get the job done. Through an extended worked example, you’ll learn how TDD works at multiple levels, using tests to drive the features and the object-oriented structure of the code, and using Mock Objects to discover and then describe relationships between objects. Along the way, the book systematically addresses challenges that development teams encounter with TDD--from integrating TDD into your processes to testing your most difficult features. Coverage includes * Implementing TDD effectively: getting started, and maintaining your momentum throughout the project* Creating cleaner, more expressive, more sustainable code* Using tests to stay relentlessly focused on sustaining quality * Understanding how TDD, Mock Objects, and Object-Oriented Design come together in the context of a real software development project* Using Mock Objects to guide object-oriented designs* Succeeding where TDD is difficult: managing complex test data, and testing persistence and concurrency From the Back Cover Foreword by Kent Beck The authors of this book have led a revolution in the craft of programming by controlling the environment in which software grows.” --Ward Cunningham “At last, a book suffused with code that exposes the deep symbiosis between TDD and OOD.

-Titulo Original : Implementing Domain-driven Design-Fabricante : Addison-Wesley Professional-Descripcion Original: “For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Implementing Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last couple decades.” -Randy Stafford, Architect At-Large, Oracle Coherence Product Development “This book is a must-read for anybody looking to put DDD into practice.”-Udi Dahan, Founder of NServiceBus Implementing Domain-Driven Design presents a top-down approach to understanding domain-driven design (DDD) in a way that fluently connects strategic patterns to fundamental tactical programming tools. Vaughn Vernon couples guided approaches to implementation with modern architectures, highlighting the importance and value of focusing on the business domain while balancing technical considerations. Building on Eric Evans’ seminal book, Domain-Driven Design, the author presents practical DDD techniques through examples from familiar domains. Each principle is backed up by realistic Java examples-all applicable to C# developers-and all content is tied together by a single case study: the delivery of a large-scale Scrum-based SaaS system for a multitenant environment. The author takes you far beyond “DDD-lite” approaches that embrace DDD solely as a technical toolset, and shows you how to fully leverage DDD’s “strategic design patterns” using Bounded Context, Context Maps, and the Ubiquitous Language. Using these techniques and examples, you can reduce time to market and improve quality, as you build software that is more flexible, more scalable, and more tightly aligned to business goals. Coverage includesGetting started the right way with DDD, so you can rapidly gain value from itUsing DDD within diverse architectures, including Hexagonal, SOA, REST, CQRS, Event-Driven, and Fabric/Grid-BasedAppropriately designing and applying Entities-and learning when to use Value Objects insteadMastering DDD’s powerful new Domain Events techniqueDesigning Repositories for ORM, NoSQL, and other databases Review “With Implementing Domain-Driven Design, Vaughn has made an important contribution not only to the literature of the Domain-Driven Design community, but also to the literature of the broader enterprise application architecture field. In key chapters on Architecture and Repositories, for example, Vaughn shows how DDD fits with the expanding array of architecture styles and persistence technologies for enterprise applications including SOA and REST, NoSQL and data grids that has emerged in the decade since Eric Evans’ seminal book was first published. And, fittingly, Vaughn illuminates the blocking and tackling of DDD the implementation of entities, value objects, aggregates, services, events, factories, and repositories with plentiful examples and valuable insights drawn from decades of practical experience. In a word, I would describe this book as thorough. For software developers of all experience levels looking to improve their results, and design and implement domain-driven enterprise applications consistently with the best current state of professional practice, Implementing Domain-Driven Design will impart a treasure trove of knowledge hard won within the DDD and enterprise application architecture communities over the last couple decades.” Randy Stafford, Architect At-Large, Oracle Coherence Product Development “Domain-Driven Design is a powerful set of thinking tools that can have a profound impact on how effective a team can be at building software-intensive systems. The thing is that many developers got lost at times when applying these thinking tools and really needed more concrete guidance. In this book, Vaughn provides the missing links between theory and practice. In addition to shedding light on many of the misundersto...

-Titulo Original : Art Of Computer Programming, The Combinatorial Algorithms, Volume 4b-Fabricante : Addison-Wesley Professional-Descripcion Original: The Art of Computer Programming is Knuths multivolume analysis of algorithms. With the addition of this new volume, it continues to be the definitive description of classical computer science. Volume 4B, the sequel to Volume 4A, extends Knuths exploration of combinatorial algorithms. These algorithms are of keen interest to software designers because . . . a single good idea can save years or even centuries of computer time. The book begins with coverage of Backtrack Programming, together with a set of data structures whose links perform delightful dances and are ideally suited to this domain. New techniques for important applications such as optimum partitioning and layout are thereby developed. Knuths writing is playful, and he includes dozens of puzzles to illustrate the algorithms and techniques, ranging from popular classics like edge-matching to more recent crazes like sudoku. Recreational mathematicians and computer scientists will not be disappointed! In the second half of the book, Knuth addresses Satisfiability, one of the most fundamental problems in all of computer science. Innovative techniques developed at the beginning of the twenty-first century have led to game-changing applications, for such things as optimum scheduling, circuit design, and hardware verification. Thanks to these tools, computers are able to solve practical problems involving millions of variables that only a few years ago were regarded as hopeless. The Mathematical Preliminaries Redux section of the book is a special treat, which presents basic techniques of probability theory that have become prominent since the original preliminaries were discussed in Volume 1. As in every volume of this remarkable series, the book includes hundreds of exercises that employ Knuths ingenious rating system, making it easy for readers of varying degrees of mathematical training to find challenges suitable to them. Detailed answers are provided to facilitate self-study. Professor Donald E. Knuth has always loved to solve problems. In Volume 4B he now promotes two brand new and practical general problem solvers, namely (0) the Dancing Links Backtracking and (1) the SAT Solver. To use them, a problem is defined declaratively (0) as a set of options, or (1) in Boolean formulae. Todays laptop computers, heavily armoured with very high speed processors and ultra large amounts of memory, are able to run either solver for problems having big input data. Each section of Volume 4B contains a multitudinous number of tough exercises which help make understanding surer. Happy reading! --Eiiti Wada, an elder computer scientist, UTokyo Donald Knuth may very well be a great master of the analysis of algorithms, but more than that, he is an incredible and tireless storyteller who always strikes the perfect balance between theory, practice, and fun. [Volume 4B, Combinatorial Algorithms, Part 2] dives deep into the fascinating exploration of search spaces (which is quite like looking for a needle in a haystack or, even harder, to prove the absence of a needle in a haystack), where actions performed while moving forward must be meticulously undone when backtracking. It introduces us to the beauty of dancing links for removing and restoring the cells of a matrix in a dance which is both simple to implement and very efficient. --Christine Solnon, Department of Computer Science, INSA Lyon Register your book for convenient access to downloads, updates, and/or corrections as they become available. Review Satisfiability solving is one of the most important computer technology advances in the last two decades. Now, with the help of it, we can find solutions for unbelievably large (say 2^1000000) combinations. Donald Knuths new volume explains the theories, algorithms, and applications of satisfiability solving, together with his famous search algorithm, Dancing Links. If you have a difficult combinatorial problem and want to solve it with a comp...

-Titulo Original : Mythical Man-month, The Essays On Software Engineering, Anniversary Edition-Fabricante : Addison-Wesley Professional-Descripcion Original: Review The classic book on the human elements of software engineering. Software tools and development environments may have changed in the 21 years since the first edition of this book, but the peculiarly nonlinear economies of scale in collaborative work and the nature of individuals and groups has not changed an epsilon. If you write code or depend upon those who do, get this book as soon as possible -- from Books, your library, or anyone else. You (and/or your colleagues) will be forever grateful. Very Highest Recommendation. Few books on software project management have been as influential and timeless as The Mythical Man-Month. With a blend of software engineering facts and thought-provoking opinions, Fred Brooks offers insight for anyone managing complex projects. These essays draw from his experience as project manager for the IBM System/360 computer family and then for OS/360, its massive software system. Now, 20 years after the initial publication of his book, Brooks has revisited his original ideas and added new thoughts and advice, both for readers already familiar with his work and for readers discovering it for the first time. The added chapters contain (1) a crisp condensation of all the propositions asserted in the original book, including Brooks central argument in The Mythical Man-Month: that large programming projects suffer management problems different from small ones due to the division of labor; that the conceptual integrity of the product is therefore critical; and that it is difficult but possible to achieve this unity; (2) Brooks view of these propositions a generation later; (3) a reprint of his classic 1986 paper No Silver Bullet; and (4) todays thoughts on the 1986 assertion, There will be no silver bullet within ten years. From the Inside Flap To my surprise and delight, The Mythical Man-Month continues to be popular after twenty years. Over 250,000 copies are in print. People often ask which of the opinions and recommendations set forth in 1975 I still hold, and which have changed, and how. Whereas I have from time to time addressed that question in lectures, I have long wanted to essay it in writing. Peter Gordon, now a Publishing Partner at Addison-Wesley, has been working with me patiently and helpfully since 1980. He proposed that we prepare an Anniversary Edition. We decided not to revise the original, but to reprint it untouched (except for trivial corrections) and to augment it with more current thoughts. Chapter 16 reprints No Silver Bullet: Essence and Accidents of Software Engineering, a 1986 IFIPS paper that grew out of my experience chairing a Defense Science Board study on military software. My co-authors of that study, and our executive secretary, Robert L. Patrick, were invaluable in bringing me back into touch with real-world large software projects. The paper was reprinted in 1987 in the IEEE Computer magazine, which gave it wide circulation. No Silver Bullet proved provocative. It predicted that a decade would not see any programming technique which would by itself bring an order-of-magnitude improvement in software productivity. The decade has a year to run; my prediction seems safe. NSB has stimulated more and more spirited discussion in the literature than has The Mythical Man-Month. Chapter 17, therefore, comments on some of the published critique and updates the opinions set forth in 1986. In preparing my retrospective and update of The Mythical Man-Month, I was struck by how few of the propositions asserted in it have been critiqued, proven, or disproven by ongoing software engineering research and experience. It proved useful to me now to catalog those propositions in raw form, stripped of supporting arguments and data. In hopes that these bald statements will invite arguments and facts to prove, disprove, update, or refine those propositions, I have included this outline as Chapter 18. Chapter 19 is the updati...

-Titulo Original : Java Concurrency In Practice-Fabricante : Addison-Wesley Professional-Descripcion Original: I was fortunate indeed to have worked with a fantastic team on the design and implementation of the concurrency features added to the Java platform in Java 5.0 and Java 6. Now this same team provides the best explanation yet of these new features, and of concurrency in general. Concurrency is no longer a subject for advanced users only. Every Java developer should read this book. --Martin Buchholz JDK Concurrency Czar, Sun Microsystems For the past 30 years, computer performance has been driven by Moores Law; from now on, it will be driven by Amdahls Law. Writing code that effectively exploits multiple processors can be very challenging. Java Concurrency in Practice provides you with the concepts and techniques needed to write safe and scalable Java programs for todays--and tomorrows--systems. --Doron Rajwan Research Scientist, Intel Corp This is the book you need if youre writing--or designing, or debugging, or maintaining, or contemplating--multithreaded Java programs. If youve ever had to synchronize a method and you werent sure why, you owe it to yourself and your users to read this book, cover to cover. --Ted Neward Author of Effective Enterprise Java Brian addresses the fundamental issues and complexities of concurrency with uncommon clarity. This book is a must-read for anyone who uses threads and cares about performance. --Kirk Pepperdine CTO, JavaPerformanceTuning.com This book covers a very deep and subtle topic in a very clear and concise way, making it the perfect Java Concurrency reference manual. Each page is filled with the problems (and solutions!) that programmers struggle with every day. Effectively exploiting concurrency is becoming more and more important now that Moores Law is delivering more cores but not faster cores, and this book will show you how to do it. --Dr. Cliff Click Senior Software Engineer, Azul Systems I have a strong interest in concurrency, and have probably written more thread deadlocks and made more synchronization mistakes than most programmers. Brians book is the most readable on the topic of threading and concurrency in Java, and deals with this difficult subject with a wonderful hands-on approach. This is a book I am recommending to all my readers of The Java Specialists Newsletter, because it is interesting, useful, and relevant to the problems facing Java developers today. --Dr. Heinz Kabutz The Java Specialists Newsletter Ive focused a career on simplifying simple problems, but this book ambitiously and effectively works to simplify a complex but critical subject: concurrency. Java Concurrency in Practice is revolutionary in its approach, smooth and easy in style, and timely in its delivery--its destined to be a very important book. --Bruce Tate Author of Beyond Java Java Concurrency in Practice is an invaluable compilation of threading know-how for Java developers. I found reading this book intellectually exciting, in part because it is an excellent introduction to Javas concurrency API, but mostly because it captures in a thorough and accessible way expert knowledge on threading not easily found elsewhere. --Bill Venners Author of Inside the Java Virtual Machine Threads are a fundamental part of the Java platform. As multicore processors become the norm, using concurrency effectively becomes essential for building high-performance applications. Java SE 5 and 6 are a huge step forward for the development of concurrent applications, with improvements to the Java Virtual Machine to support high-performance, highly scalable concurrent classes and a rich set of new concurrency building blocks. In Java Concurrency in Practice, the creators of these new facilities explain not only how they work and how to use them, but also the motivation and design patterns behind them. However, developing, testing, and debugging multithreaded programs can still be very difficult; it is all too easy to create concurrent programs that appear to work, but fail when it matters most: in production, under heavy load. Java Concurrency in Practice arms readers with both the theoretical underpinnings and concrete techniques for building reliable, scalable, maintainable concurrent applications. Rather than simply offering an inventory of concurrency APIs and mechanisms, it provides design rules, patterns, and mental models that make it easier to build concurrent programs that are both correct and performant. This book covers: Basic concepts of concurrency and thread safety Techniques for building and composing thread-safe classes Using the concurrency building blocks in java.util.concurrent Performance optimization dos and donts Testing concurrent programs Advanced topics such as atomic variables, nonblocking algorithms, and the Java Memory Mode...
