The second volume in the Write Great Code series supplies the critical information that today's computer science students don't often get from college and university courses: How to carefully choose their high-level language statements to produce efficient code. Write Great Code, Volume 2: Thinking Low-Level, Writing High-Level, teaches software engineers how compilers translate high-level language statements and data structures into machine code. Armed with this knowledge, a software engineer can make an informed choice concerning the use of those high-level structures to help the compiler produce far better machine code--all without having to give up the productivity and portability benefits of using a high-level language.

各位程序员一定希望自己编写的代码是能让老板赞赏、满意的代码；是能让客户乐意掏钱购买的代码；是能让使用者顺利使用的代码；是能让同行欣赏赞誉的代码；是能让自己引以为豪的卓越代码。本书作者为希望能编写出卓越代码的人提供了自己积累的关于卓越编程的真知灼见。它弥补了计算机科学和工程课程中被忽略的一个部分——底层细节，而这正是构建卓越代码的基石。具体内容包括：计算机数据表示法，二进制数学运算与位运算，内存组织与内存访问，数据类型及其表示，布尔逻辑与数字设计，CPU体系结构，CPU指令集的体系结构，内存体系与内存组织，计算机系统如何与外界通信等。...

《Ruby元编程》以案例形式循序渐进讲解Ruby对象模型原理和高级应用技巧，堪称动态语言的设计模式。书中讲述的各种Ruby编程模式，完全可以应用于其他动态语言（甚至静态语言）。本书不仅适合Ruby程序员阅读，也适合对动态编程 语言和面向对象编程感兴趣的读者阅读。所有对程序设计理论感兴趣的人都能从中获益。Ruby之父松本行弘作序推荐。

Unlike high-level languages such as Java and C++, assembly language is much closer to the machine code that actually runs computers; it's used to create programs or modules that are very fast and efficient, as well as in hacking exploits and reverse engineering Covering assembly language in the Pentium microprocessor environment, this code-intensive guide shows programmers how to create stand-alone assembly language programs as well as how to incorporate assembly language libraries or routines into existing high-level applications Demonstrates how to manipulate data, incorporate advanced functions and libraries, and maximize application performance Examples use C as a high-level language, Linux as the development environment, and GNU tools for assembling, compiling, linking, and debugging

本书详细地讨论了如何编写健壮高效的代码以及模块设计技术。本书采用了自问自答的语言风格，它讨论了实际程序设计中普遍存在的，又非常不易察觉的问题，并且进行了深刻的分析，提出了具有广泛意义的解决方案。本书值得每个想成为优秀c++程序员的人阅读。我相信，任何c++程序员都会在本书的阅读过程中有许多收获，甚至有一种醍醐灌顶，恍然大悟的收获和喜悦。

这不仅仅是一本关于Perl的书籍，更是一本独一无二的开发者自己介绍该语言及其文化的书籍。Larry Wall是Perl的开发者，他就这种语言的未来发展方向提出了自己的看法。Tom Christiansen是最早的几个拥护者之一，也是少数几个在错综复杂的中游刃有余的人之一。Jon Orwant是《Perl Journal》的主编，该杂志把Perl社区组合成了一个共同的论坛，以进行Perl新的开发。
