Although the number of commercial Java games is still small compared to those written in C or C++, the market is expanding rapidly. Recent updates to Java make it faster and easier to create powerful gaming applications-particularly Java 3D-is fueling an explosive growth in Java games. Java games like Puzzle Pirates, Chrome, Star Wars Galaxies, Runescape, Alien Flux, Kingdom of Wars, Law and Order II, Roboforge, Tom Clancy's Politika, and scores of others have earned awards and become bestsellers. Java developers new to graphics and game programming, as well as game developers new to Java 3D, will find Killer Game Programming in Java invaluable. This new book is a practical introduction to the latest Java graphics and game programming technologies and techniques. It is the first book to thoroughly cover Java's 3D capabilities for all types of graphics and game development projects. Killer Game Programming in Java is a comprehensive guide to everything you need to know to program cool, testosterone-drenched Java games. It will give you reusable techniques to create everything from fast, full-screen action games to multiplayer 3D games. In addition to the most thorough coverage of Java 3D available, Killer Game Programming in Java also clearly details the older, better-known 2D APIs, 3D sprites, animated 3D sprites, first-person shooter programming, sound, fractals, and networked games. Killer Game Programming in Java is a must-have for anyone who wants to create adrenaline-fueled games in Java.

大数运算是加密和安全领域必不可少的一部分，要想实现它，既需要相应的数学理论知识，又需要一定的编程技巧。对于每一个初学者，要想掌握它，必定要花费大量时间查阅数学书本和c语言教程（也可能是别的语言）。本书作者为了方便初学者学习及业内人士使用，开发了一个免费的大数运算库，即LibTomMath项目。结合LibTomMath库，由浅入深对各种大数运算的算法进行了阐述。对每一种运算一般都列出多种算法，并对其性能进行比较。本书适合于对算法、IT安全、加密领域感兴趣的读者阅读。

《Python高级编程》通过大量的实例，介绍了Python语言的最佳实践和敏捷开发方法，并涉及整个软件生命周期的高级主题，诸如持续集成、版本控制系统、包的发行和分发、开发模式、文档编写等。《Python高级编程》首先介绍如何设置最优的开发环境，然后以Python敏捷开发方法为线索，阐述如何将已被验证的面向对象原则应用到设计中。这些内容为开发人员和项目管理人员提供了整个软件工程中的许多高级概念以及专家级的建议，其中有些内容的意义甚至超出了Python语言本身

本书通过编写一个个小巧、有趣的游戏来教授Python编程，并且采用直接展示了游戏的源代码，通过实例来解释编程的原理的方式。全书共21章，14个游戏程序和示例贯穿其中，介绍了Python基础知识、数据类型、函数、流程控制、程序调试、流程图设计、字符串操作、列表和字典、图形和动画、碰撞检测、声音和图像等方方面面的程序设计知识。本书可以帮助读者在轻松有趣的过程中，掌握Python游戏编程的基本技能。
