"Every programming language has its quirks. This lively book reveals oddities of the Java programming language through entertaining and thought-provoking programming puzzles." --Guy Steele, Sun Fellow and coauthor of The Java(t) Language Specification "I laughed, I cried, I threw up (my hands in admiration)." --Tim Peierls, president, Prior Artisans LLC, and member of the JSR 166 Expert Group How well do you really know Java? Are you a code sleuth? Have you ever spent days chasing a bug caused by a trap or pitfall in Java or its libraries? Do you like brainteasers? Then this is the book for you! In the tradition of Effective Java(t), Bloch and Gafter dive deep into the subtleties of the Java programming language and its core libraries. Illustrated with visually stunning optical illusions, Java(t) Puzzlers features 95 diabolical puzzles that educate and entertain. Anyone with a working knowledge of Java will understand the puzzles, but even the most seasoned veteran will find them challenging. Most of the puzzles take the form of a short program whose behavior isn't what it seems. Can you figure out what it does? Puzzles are grouped loosely according to the features they use, and detailed solutions follow each puzzle. The solutions go well beyond a simple explanation of the program's behavior--they show you how to avoid the underlying traps and pitfalls for good. A handy catalog of traps and pitfalls at the back of the book provides a concise taxonomy for future reference. Solve these puzzles and you'll never again fall prey to the counterintuitive or obscure behaviors that can fool even the most experienced programmers.

您知道吗？许多身体不适都和不健康的饮食方式有关——不断悄悄增加的体重减不下来、血压过高、容易疲劳、工作中容易犯困、注意力不能持续集中……这些困扰我们的疾病和身体不适，九成以上都是由“血糖值”过高或数值的急剧升降造成的。
不科学的饮食方式，正在让越来越多的人陷入“肥胖→衰老→患病”的怪圈。那么，正确的饮食方式是什么？如何科学地控糖、减肥，从而保持健康、延缓衰老、远离疾病呢？
这本风靡日本的科学饮食教科书将给你答案——从医38年的医学博士牧田善二先生基于多年的深耕研究、丰富的临床经验和最新的统计数据，揭开了造成肥胖、衰老和疾病的秘密，总结出了68项健康饮食的具体措施，帮助我们科学管理饮食、改善生活习惯、守护好自己和家人的身体健康，调整身心，找回活力！

细节决定成败，思路清晰、言简意赅的代码让程序员一目了然；而格式凌乱、拖沓冗长的代码让程序员一头雾水。除了可以正确运行以外，优秀的代码必须具备良好的可读性，编写的代码要使其他人能在最短的时间内理解才行。本书旨在强调代码对人的友好性和可读性。
本书关注编码的细节，总结了很多提高代码可读性的小技巧，看似都微不足道，但是对于整个软件系统的开发而言，它们与宏观的架构决策、设计思想、指导原则同样重要。编码不仅仅只是一种技术，也是一门艺术，编写可读性高的代码尤其如此。如果你要成为一位优秀的程序员，要想开发出高质量的软件系统，必须从细处着手，做到内外兼修，本书将为你提供有效的指导。

"In most fields the great work is done early on. The paintings made between 1430 and 1500 are still unsurpassed. Shakespeare appeared just as professional theater was being born, and pushed the medium so far that every playwright since has had to live in his shadow. Albrecht Durer did the same thing with engraving, and Jane Austen with the novel.

为什么微软公司的管理层晚上睡觉的时候会担心一个长发的、名叫Richard Stallman的反叛高手？为什么世界最聪明的程序员都尊敬地将此人称为“St.Ignucius”?这样一个倔强的、少年老成的男孩是如何迷恋于开发出能打败软件巨人的优秀产品的？本书就将跟随着这位古怪天才的革命之路，看看他如何从一个孤僻的开才到流浪十年，最终成为受人尊敬又饱受非议的改革者。通过全方位地接触Stallman、他的家庭、追随他的程序高手和业界勾勒了了一位改变了世界的自由斗士的肖像。没有人会对这位备受争议的自由软件基金会的创始人无动于衷。作为优秀的程序员，MacArthur天才奖获得者，自称自闭症边缘人士，Stallman是这场通过彻底改变软件游戏规则来击败微软件的斗争中的开路先锋。对于Stallman来说，自由软件只是一种精神上的需要。自从1980年遇到非免费的打印机软件开始，他就将自己的一生投入到消灭私有代码的斗争中去。在救世主意愿的驱使下，再加上他世界级的编程水准，以及不可思议的号召力，Stallman的自由运动获得了每一位程序员的支持。1983年，Stallman发布了GNU Maniffesto，发起了一个大胆的项目，目的是开发出一种免费的用于替代Unix操作系统的产品。而且他在他自己的软件许可（即GPL，General Public License）中插入copyleft一词，从而他向传统的知识产权系统发起了挑战。微软公司的首席技术官员Craig Mundie称此举是“对独立商用软件构成的根本性破坏。”这本煽动性的编年史以一种新的视角让其崇拜者和反对者重新认识这位神秘的高科技罗宾汉，让读者重新理解他当初要重塑软件产业未来的诺言。资深自由作者Sam Williams花了很多年的时间来研究高技术产业的未来，特别关注了软件开发问题。他为Upside Today和BeOpen.com等出版物撰写固定的专栏。他还是Arguing A.I.:The Battle for Twenty-First Century Science一书的作者。

Mozilla is not just a browser. Mozilla is also a framework that allows developers to create cross-platform applications. This framework is made up of JavaScript, CSS (Cascading Style Sheets), and Mozilla's XUL (XML-based User-interface Language) as well as the Gecko rendering engine, XBL (eXtensible Binding Language), XPCOM (Mozilla's component model), and several other components. This volume explains how applications are created with Mozilla and provides step-by-step information about how you can create your own programs using Mozilla's powerful cross-platform development framework. This book also shows examples of many different types of existing applications to demonstrate some of the possibilities of Mozilla application development. One of Mozilla's biggest advantages for a developer is that Mozilla-based applications are cross-platform, meaning programs work the same on Windows as they do on Linux or the Mac OS. Working through the book, you are introduced to the Mozilla development environment and after installing Mozilla, you quickly learn to create simple applications. After the initial satisfaction of developing your own portable applications, the book branches into topics on modular development and packaging your application. In order to build more complex applications, coverage of XUL, JavaScript, and CSS allow you to discover how to customize and build out your application shell. The second half of the book explores more advanced topics including UI enhancement, localization, and remote distribution. Mozilla 1.0 was released on June 5th, 2002, after more than four years of development as an open source project. This book has been written so that all of the information and examples will work with this release and any of the 1.0.x maintenance releases. In addition to Netscape's Mozilla-based browsers (Netscape 6.x and 7.x), the Mozilla framework has been used to create other browsers such as Galeon and Chimera, and chat clients such as ChatZilla and JabberZilla. Developers have also used Mozilla to create games, development tools, browser enhancements, as well as all sorts of other types of applications.

On the World Wide Web, speed and efficiency are vital. Users have little patience for slow web pages, while network administrators want to make the most of their available bandwidth. A properly designed web cache reduces network traffic and improves access times to popular web sites--a boon to network administrators and web users alike. Web Caching hands you all the technical information you need to design, deploy, and operate an effective web caching service. It starts with the basics of how web caching works, from the HTTP headers that govern cachability to cache validation and replacement algorithms. Topics covered in this book include:
Designing an effective cache solution
Configuring web browsers to use a cache
Setting up a collection of caches that can talk to each other
Configuring an interception cache or proxy
Monitoring and fine-tuning the performance of a cache
Configuring web servers to cooperate with web caches
Benchmarking cache products
The book also covers the important political aspects of web caching, including privacy, intellectual property, and security issues. Internet service providers, large corporations, or educational institutions--in short, any network that provides connectivity to a wide variety of users--can reap enormous benefit from running a well-tuned web caching service. Web Caching shows you how to do it right.

Slow websites infuriate users. Lots of people can visit your web site or use your web application - but you have to be prepared for those visitors, or they won't come back. Your sites need to be built to withstand the problems success creates. "Building Scalable Web Sites" looks at a variety of techniques for creating sites which can keep users cheerful even when there are thousands or millions of them. Flickr.com developer, Cal Henderson, explains how to build sites so that large numbers of visitors can enjoy them. Henderson examines techniques that go beyond sheer speed, exploring how to coordinate developers, support international users, and integrate with other services from email to SOAP to RSS to the APIs exposed by many Ajax-based web applications. This book uncovers the secrets that you need to know for back-end scaling, architecture and failover so your websites can handle countless requests. You'll learn how to take the "poor man's web technologies" - Linux, Apache, MySQL and PHP or other scripting languages - and scale them to compete with established "store bought" enterprise web technologies. Toward the end of the book, you'll discover techniques for keeping web applications running with event monitoring and long-term statistical tracking for capacity planning. If you're about to build your first dynamic website, then "Building Scalable Web Sites" isn't for you. But if you're an advanced developer who's ready to realize the cost and performance benefits of a comprehensive approach to scalable applications, then let your fingers do the walking through this convenient guide.
