Even bad code can function. But if code isn’t clean, it can bring a development organization to its knees. Every year, countless hours and significant resources are lost because of poorly written code. But it doesn’t have to be that way.Noted software expert Robert C. Martin, presents a revolutionary paradigm with Clean Code: A Handbook of Agile Software Craftsmanship. Martin, who has helped bring agile principles from a practitioner’s point of view to tens of thousands of programmers, has teamed up with his colleagues from Object Mentor to distill their best agile practice of cleaning code “on the fly” into a book that will instill within you the values of software craftsman, and make you a better programmer―but only if you work at it.What kind of work will you be doing? You’ll be reading code―lots of code. And you will be challenged to think about what’s right about that code, and what’s wrong with it. More importantly you will be challenged to reassess your professional values and your commitment to your craft.Clean Codeis divided into three parts. The first describes the principles, patterns, and practices of writing clean code. The second part consists of several case studies of increasing complexity. Each case study is an exercise in cleaning up code―of transforming a code base that has some problems into one that is sound and efficient. The third part is the payoff: a single chapter containing a list of heuristics and “smells” gathered while creating the case studies. The result is a knowledge base that describes the way we think when we write, read, and clean code.Readers will come away from this book understandingHow to tell the difference between good and bad code How to write good code and how to transform bad code into good code How to create good names, good functions, good objects, and good classes How to format code for maximum readability How to implement complete error handling without obscuring code logic How to unit test and practice test-driven development What “smells” and heuristics can help you identify bad code This book is a must for any developer, software engineer, project manager, team lead, or systems analyst with an interest in producing better code.

A newer edition of this book is now available; click on "See all formats and editions" above for details.This book addresses the topic of software design: how to decompose complex software systems into modules (such as classes and methods) that can be implemented relatively independently. The book first introduces the fundamental problem in software design, which is managing complexity. It then discusses philosophical issues about how to approach the software design process, and it presents a collection of design principles to apply during software design. The book also introduces a set of red flags that identify design problems. You can apply the ideas in this book to minimize the complexity of large software systems, so that you can write software more quickly and cheaply.

Refactoring is about improving the design of existing code. It is the process of changing a software system in such a way that it does not alter the external behavior of the code, yet improves its internal structure. With refactoring you can even take a bad design and rework it into a good one. This book offers a thorough discussion of the principles of refactoring, including where to spot opportunities for refactoring, and how to set up the required tests. There is also a catalog of more than 40 proven refactorings with details as to when and why to use the refactoring, step by step instructions for implementing it, and an example illustrating how it works The book is written using Java as its principle language, but the ideas are applicable to any OO language.

“In this second edition of Extreme Programming Explained, Kent Beck organizes and presents five years’ worth of experiences, growth, and change revolving around XP. If you are seriously interested in understanding how you and your team can start down the path of improvement with XP, you must read this book.”― Francesco Cirillo, Chief Executive Officer, XPLabs S.R.L. “The first edition of this book told us what XP was―it changed the way many of us think about software development. This second edition takes it farther and gives us a lot more of the ‘why’ of XP, the motivations and the principles behind the practices. This is great stuff. Armed with the ‘what’ and the ‘why,’ we can now all set out to confidently work on the ‘how’: how to run our projects better, and how to get agile techniques adopted in our organizations.”― Dave Thomas, The Pragmatic Programmers LLC “This book is dynamite! It was revolutionary when it first appeared a few years ago, and this new edition is equally profound. For those who insist on cookbook checklists, there’s an excellent chapter on ‘primary practices,’ but I urge you to begin by truly contemplating the meaning of the opening sentence in the first chapter of Kent Beck’s book: ‘XP is about social change.’ You should do whatever it takes to ensure that every IT professional and every IT manager―all the way up to the CIO―has a copy of Extreme Programming Explained on his or her desk.”― Ed Yourdon, author and consultant “XP is a powerful set of concepts for simplifying the process of software design, development, and testing. It is about minimalism and incrementalism, which are especially useful principles when tackling complex problems that require a balance of creativity and discipline.”― Michael A. Cusumano, Professor, MIT Sloan School of Management, and author of The Business of Software “ Extreme Programming Explained is the work of a talented and passionate craftsman. Kent Beck has brought together a compelling collection of ideas about programming and management that deserves your full attention. My only beef is that our profession has gotten to a point where such common-sense ideas are labeled ‘extreme.’...”― Lou Mazzucchelli, Fellow, Cutter Business Technology Council “If your organization is ready for a change in the way it develops software, there’s the slow incremental approach, fixing things one by one, or the fast track, jumping feet first into Extreme Programming. Do not be frightened by the name, it is not that extreme at all. It is mostly good old recipes and common sense, nicely integrated together, getting rid of all the fat that has accumulated over the years.”― Philippe Kruchten, UBC, Vancouver, British Columbia “Sometimes revolutionaries get left behind as the movement they started takes on a life of its own. In this book, Kent Beck shows that he remains ahead of the curve, leading XP to its next level. Incorporating five years of feedback, this book takes a fresh look at what it takes to develop better software in less time and for less money. There are no silver bullets here, just a set of practical principles that, when used wisely, can lead to dramatic improvements in software development productivity.”― Mary Poppendieck, author of Lean Software Development: An Agile Toolkit “Kent Beck has revised his classic book based on five more years of applying and teaching XP. He shows how the path to XP is both

What is it about the top tech product companies such as Amazon, Apple, Google, Netflix and Tesla that enables their record of consistent innovation?Most people think it’s because these companies are somehow able to find and attract a level of talent that makes this innovation possible. But the real advantage these companies have is not so much who they hire, but rather how they enable their people to work together to solve hard problems and create extraordinary products.As legendary Silicon Valley coach--and coach to the founders of several of today’s leading tech companies--Bill Campbell said, “Leadership is about recognizing that there's a greatness in everyone, and your job is to create an environment where that greatness can emerge.”The goal of EMPOWERED is to provide you, as a leader of product management, product design, or engineering, with everything you’ll need to create just such an environment.As partners at The Silicon Valley Product Group, Marty Cagan and Chris Jones have long worked to reveal the best practices of the most consistently innovative companies in the world. A natural companion to the bestseller INSPIRED, EMPOWERED tackles head-on the reason why most companies fail to truly leverage the potential of their people to innovate: product leadership.The book covers: what it means to be an empowered product team, and how this is different from the “feature teams” used by most companies to build technology products recruiting and coaching the members of product teams, first to competence, and then to reach their potential creating an inspiring product vision along with an insights-driven product strategy translating that strategy into action by empowering teams with specific objectives―problems to solve―rather than features to build redefining the relationship of the product teams to the rest of the company detailing the changes necessary to effectively and successfully transform your organization to truly empowered product teamsEMPOWERED puts decades of lessons learned from the best leaders of the top technology companies in your hand as a guide. It shows you how to become the leader your team and company needs to not only survive but thrive.

What’s so special about design patterns?At any given moment, someone struggles with the same software design problems you have. And, chances are, someone else has already solved your problem. This edition of Head First Design Patterns―now updated for Java 8―shows you the tried-and-true, road-tested patterns used by developers to create functional, elegant, reusable, and flexible software. By the time you finish this book, you’ll be able to take advantage of the best design practices and experiences of those who have fought the beast of software design and triumphed.What’s so special about this book?We think your time is too valuable to spend struggling with new concepts. Using the latest research in cognitive science and learning theory to craft a multi-sensory learning experience, Head First Design Patterns uses a visually rich format designed for the way your brain works, not a text-heavy approach that puts you to sleep.

Increase profitability, elevate work culture, and exceed productivity goals through DevOps practices.More than ever, the effective management of technology is critical for business competitiveness. For decades, technology leaders have struggled to balance agility, reliability, and security. The consequences of failure have never been greater―whether it's the healthcare.gov debacle, cardholder data breaches, or missing the boat with Big Data in the cloud.And yet, high performers using DevOps principles, such as Google, Amazon, Facebook, Etsy, and Netflix, are routinely and reliably deploying code into production hundreds, or even thousands, of times per day.Following in the footsteps of The Phoenix Project, The DevOps Handbook shows leaders how to replicate these incredible outcomes, by showing how to integrate Product Management, Development, QA, IT Operations, and Information Security to elevate your company and win in the marketplace.

You need to get value from your software project. You need it "free, now, and perfect." We can't get you there, but we can help you get to "cheaper, sooner, and better." This book leads you from the desire for value down to the specific activities that help good Agile projects deliver better software sooner, and at a lower cost. Using simple sketches and a few words, the author invites you to follow his path of learning and understanding from a half century of software development and from his engagement with Agile methods from their very beginning.The book describes software development, starting from our natural desire to get something of value. Each topic is described with a picture and a few paragraphs. You're invited to think about each topic; to take it in. You'll think about how each step into the process leads to the next. You'll begin to see why Agile methods ask for what they do, and you'll learn why a shallow implementation of Agile can lead to only limited improvement.This is not a detailed map, nor a step-by-step set of instructions for building the perfect project. There is no map or instructions that will do that for you.You need to build your own project, making it a bit more perfect every day. To do that effectively, you need to build up an understanding of the whole process.This book points out the milestones on your journey of understanding the nature of software development done well. It takes you to a location, describes it briefly, and leaves you to explore and fill in your own understanding.What You Need:You'll need your Standard Issue Brain, a bit of curiosity, and a desire to build your own understanding rather than have someone else's detailed ideas poured into your head.

The New York Times best-selling team leadership handbook for modern executives, managers, and organizationsAfter her first two weeks observing the problems at DecisionTech, Kathryn Petersen, its new CEO, had more than a few moments when she wondered if she should have taken the job. But Kathryn knew there was little chance she would have turned it down. After all, retirement had made her antsy, and nothing excited her more than a challenge.

She must unite a team in such disarray that it threatens to derail the entire company.Equal parts leadership fable and business handbook, this definitive source on teamwork by Patrick Lencioni reveals the five behavioral tendencies that go to the heart of why even the best teams struggle. He offers a powerful model and step-by-step guide for overcoming those dysfunctions and getting every one rowing in the same direction.Today, the lessons in The Five Dysfunctions of a Team are more relevant than ever. This special anniversary edition celebrates one of the best-selling business books of all time with a new foreword from the author that reflects on its legacy and lessons.

The classic guide to how computers work, updated with new chapters and interactive graphics"For me, Code was a revelation. It was the first book about programming that spoke to me. It started with a story, and it built up, layer by layer, analogy by analogy, until I understood not just the Code, but the System. Code is a book that is as much about Systems Thinking and abstractions as it is about code and programming. Code teaches us how many unseen layers there are between the computer systems that we as users look at every day and the magical silicon rocks that we infused with lightning and taught to think."- Scott Hanselman, Partner Program Director, Microsoft, and host of HanselminutesComputers are everywhere, most obviously in our laptops and smartphones, but also our cars, televisions, microwave ovens, alarm clocks, robot vacuum cleaners, and other smart appliances. Have you ever wondered what goes on inside these devices to make our lives easier but occasionally more infuriating?For more than 20 years, readers have delighted in Charles Petzold's illuminating story of the secret inner life of computers, and now he has revised it for this new age of computing. Cleverly illustrated and easy to understand, this is the book that cracks the mystery. You'll discover what flashlights, black cats, seesaws, and the ride of Paul Revere can teach you about computing, and how human ingenuity and our compulsion to communicate have shaped every electronic device we use.This new expanded edition explores more deeply the bit-by-bit and gate-by-gate construction of the heart of every smart device, the central processing unit that combines the simplest of basic operations to perform the most complex of feats. Petzold's companion website, CodeHiddenLanguage.com, uses animated graphics of key circuits in the book to make computers even easier to comprehend.In addition to substantially revised and updated content, new chapters include: Chapter 18: Let's Build a Clock! Chapter 21: The Arithmetic Logic Unit Chapter 22: Registers and Busses Chapter 23: CPU Control Signals Chapter 24: Jumps, Loops, and Calls Chapter 28: The World BrainFrom the simple ticking of clocks to the worldwide hum of the internet, Code reveals the essence of the digital revolution.
