Data is at the center of many challenges in system design today. Difficult issues need to be figured out, such as scalability, consistency, reliability, efficiency, and maintainability. In addition, we have an overwhelming variety of tools, including relational databases, NoSQL datastores, stream or batch processors, and message brokers. What are the right choices for your application? How do you make sense of all these buzzwords?In this practical and comprehensive guide, author Martin Kleppmann helps you navigate this diverse landscape by examining the pros and cons of various technologies for processing and storing data. Software keeps changing, but the fundamental principles remain the same. With this book, software engineers and architects will learn how to apply those ideas in practice, and how to make full use of data in modern applications. Peer under the hood of the systems you already use, and learn how to use and operate them more effectively Make informed decisions by identifying the strengths and weaknesses of different tools Navigate the trade-offs around consistency, scalability, fault tolerance, and complexity Understand the distributed systems research upon which modern databases are built Peek behind the scenes of major online services, and learn from their architectures

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.

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.

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.

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.
