Refactoring has proven its value in a wide range of development projects--helping software professionals improve system designs, maintainability, extensibility, and performance. Now, for the first time, leading agile methodologist Scott Ambler and renowned consultant Pramodkumar Sadalage introduce powerful refactoring techniques specifically designed for database systems. Ambler and Sadalage demonstrate how small changes to table structures, data, stored procedures, and triggers can significantly enhance virtually any database design--without changing semantics. You'll learn how to evolve database schemas in step with source code--and become far more effective in projects relying on iterative, agile methodologies. This comprehensive guide and reference helps you overcome the practical obstacles to refactoring real-world databases by covering every fundamental concept underlying database refactoring. Using start-to-finish examples, the authors walk you through refactoring simple standalone database applications as well as sophisticated multi-application scenarios. You'll master every task involved in refactoring database schemas, and discover best practices for deploying refactorings in even the most complex production environments. The second half of this book systematically covers five major categories of database refactorings. You'll learn how to use refactoring to enhance database structure, data quality, and referential integrity; and how to refactor both architectures and methods. This book provides an extensive set of examples built with Oracle and Java and easily adaptable for other languages, such as C#, C++, or VB.NET, and other databases, such as DB2, SQL Server, MySQL, and Sybase. Using this book's techniques and examples, you can reduce waste, rework, risk, and cost--and build database systems capable of evolving smoothly, far into the future.

Architects look at thousands of buildings during their training, and study critiques of those buildings written by masters. In contrast, most software developers only ever get to know a handful of large programs well—usually programs they wrote themselves—and never study the great programs of history. As a result, they repeat one another's mistakes rather than building on one another's successes.
Our goal is to change that. In these two books, the authors of four dozen open source applications explain how their software is structured, and why. What are each program's major components? How do they interact? And what did their builders learn during their development? In answering these questions, the contributors to these books provide unique insights into how they think.
If you are a junior developer, and want to learn how your more experienced colleagues think, these books are the place to start. If you are an intermediate or senior developer, and want to see how your peers have solved hard design problems, these books can help you too.

当代软件技术领域最重要的著作，中文版首次出版！
《大教堂与集市》是开源运动的《圣经》，颠覆了传统的软件开发思路，影响了整个软件开发领域。作者Eric S. Raymond是开源运动的旗手、黑客文化第一理论家，他讲述了开源运动中惊心动魄的故事，提出了大量充满智慧的观念和经过检验的知识，给所有软件开发人员带来启迪。本书囊括了作者最著名的“五部曲”，并经过作者的全面更新，增加了大量注释，提高了可读性，是经典收藏。
开源运动对软件业和互联网带来了巨大影响，本书作为开源运动的独立宣言，其影响力远远超出编程领域，如果想在互联网时代做生意，这本书是必读经典。
详细内容：
本书是开源运动的独立宣言，它清晰、透彻和准确地描述了开源运动的理论与实际应用，对开源软件运动的成功和Linux操作系统的广泛采用，都起到了至关重要的作用。
作者Eric S. Raymond是开源运动和黑客文化的元老级人物，他是INTERCAL编程语言的主要创作者之一，是Fetchmail程序的作者，并为EMACS编辑器作出过贡献。1997年以后，他成为开放源代码运动的主要理论家，以及开放源代码促进会的主要创办人之一。
作者观察到，在互联网世界里，有一种与传统软件开发模式（大教堂模式）截然不同的全新的模式：集市模式。大教堂模式是封闭的、垂直的、集中式的开发模式，反映一种由权利关系所预先控制的层级制度；而集市模式则是并行的、点对点的、动态的多人协同开发模式，开发者之间通常仅仅靠互联网联系，在这种貌似混乱而无序的开发环境中，居然产生了质量极高和极具效率与生命力的软件，产生了诸如Linux这种世界级的操作系统，这是怎么做到的呢？
作者通过亲自实践，研究了这种模式的成功原因和主要特点，给出了19条软件开发的真知灼见，解释了黑客愿意无偿贡献自己代码的动机，研究了开源软件的经济动力和盈利机制，并预测了软件业将必然面临的根本性变革。
作者在书中对“黑客”（hacker）这一通常被误用的称呼做了正名，指出黑客并不是计算机犯罪分子，而是醉心于软件和网络的编程高手，是乐于分享和喜欢突破极限的问题解决专家、天才发明家和艺术家。对于想要成为一名黑客的读者，作者指出了黑客应具备的基本态度、黑客和骇客的本质区别、黑客应有的格调和如何掌握黑客的基本技能，作者指出：黑客文化靠声誉运转，只有当其他黑客一致称你为黑客时，你才是黑客。
本书囊括了作者被业界称为“五部曲”的核心著作：“黑客圈简史”（A Brief History of Hackerdom）、“大教堂和大集市”（The Cathedral and the Bazaar）、“如何成为一名黑客”（How To Become A Hacker）、“开拓心智层”（Homesteading the Noosphere）和“魔法锅”（The Magic Cauldron）。其中最著名的当属“大教堂和大集市”。本书在开源运动中的地位相当于基督教的《圣经》，用黑客们的话说，这是“黑客藏经阁”的第一收藏。
本书并不只是在讲开源和黑客，所有关心软件开发和IT发展的人，都应该花些时间通读全书，书中给出了大量充满智慧的观念和有趣的知识，如命令体系、礼物文化、以少成多、内部市场、竞次、反公地模型、委员会设计、同侪声誉、模因工程、SNAFU现象、进化不利条件、软件业是服务行业、组织结构决定产品结构、准入门槛越低稳定性越高、程序员是资产而非成本等，这些内容一定会给你带来新的启示和思考。

Java 11版本包含一个全新的垃圾收集器ZGC，它由Oracle开发，承诺在数TB的堆上具有非常低的暂停时间。ZGC是2017年Oracle公司贡献给OpenJDK社区的，正式成为OpenJDK的开源项目。ZGC 所针对的是这些在未来普遍存在的大容量内存：TB 级别的堆容量，具有很低的停顿时间（小于 10 毫秒），对整体应用性能的影响也很小（对吞吐量的影响低于 15％）。ZGC 所采用的机制也可以在未来进行扩展，以支持一些令人兴奋的特性，如多层堆（用于热对象的 DRAM 和用于低频访问对象的 NVMe 闪存）
或压缩堆。
本书详细介绍ZGC涉及的基本概念和运行原理，以及调优方法。主要内容共9章，主要
内容有：垃圾回收器概述、ZGC内存管理、ZGC线程、ZGC垃圾回收算法的设计、ZGC日
志解读、ZGC参数和基准测试、ZGC的编译调试、ZGC特性总结和展望、ZGC的编译调试、Shenandoah简介等。

Netflix cofounder Reed Hastings reveals for the first time the unorthodox culture behind one of the world's most innovative, imaginative, and successful companies
There's never before been a company like Netflix. Not only because it has led a revolution in the entertainment industries; or because it generates billions of dollars in annual revenue; or even because it is watched by hundreds of millions of people in nearly 200 countries. When Reed Hastings co-founded Netflix, he developed a set of counterintuitive and radical management principles, defying all tradition and expectation, which would allow the company to reinvent itself over and over on the way to becoming one of the most loved brands in the world.
Rejecting the conventional wisdom under which other companies operate, Reed set new standards, valuing people over process, emphasizing innovation over efficiency, and giving employees context, not controls. At Netflix, adequate performance gets a generous severance and hard work is irrelevant. At Netflix, you don't try to please your boss, you give candid feedback instead. At Netflix, employees never need approval, and the company always pays top of market. When Hastings and his team first devised these principles, the implications were unknown and untested, but over just a short period of time they have led to unprecedented flexibility, speed, and boldness. The culture of freedom and responsibility has allowed the company to constantly grow and change as the world, and its members' needs, have also transformed.
Here for the first time, Hastings and Erin Meyer, bestselling author of The Culture Map and one of the world's most influential business thinkers, dive deep into the controversial philosophies at the heart of the Netflix psyche, which have generated results that are the envy of the business world. Drawing on hundreds of interviews with current and past Netflix employees from around the globe and never-before-told stories of trial and error from his own career, No Rules Rules is the full, fascinating, and untold story of a unique company making its mark on the world.
