Perl is a powerful programming language that has grown in popularity since it first appeared in 1988. The first edition of this book, "Programming Perl," hit the shelves in 1990, and was quickly adopted as the undisputed bible of the language. Since then, Perl has grown with the times, and so has this book. "Programming Perl" is not just a book about Perl. It is also a unique introduction to the language and its culture, as one might expect only from its authors. Larry Wall is the inventor of Perl, and provides a unique perspective on the evolution of Perl and its future direction. Tom Christiansen was one of the first champions of the language, and lives and breathes the complexities of Perl internals as few other mortals do. Jon Orwant is the editor of "The Perl Journal," which has brought together the Perl community as a common forum for new developments in Perl. Any Perl book can show the syntax of Perl's functions, but only this one is a comprehensive guide to all the nooks and crannies of the language. Any Perl book can explain typeglobs, pseudohashes, and closures, but only this one shows how they really work. Any Perl book can say that "my" is faster than "local," but only this one explains why. Any Perl book can have a title, but only this book is affectionately known by all Perl programmers as "The Camel." This third edition of "Programming Perl" has been expanded to cover version 5.6 of this maturing language. New topics include threading, the compiler, Unicode, and other new features that have been added since the previous edition.

"Learning Perl", better known as "the Llama book", starts the programmer on the way to mastery. Written by three prominent members of the Perl community who each have several years of experience teaching Perl around the world, this latest edition has been updated to account for all the recent changes to the language up to Perl 5.8. Perl is the language for people who want to get work done. It started as a tool for UNIX system administrators who needed something powerful for small tasks. Since then, Perl has blossomed into a full-featured programming language used for web programming, database manipulation, XML processing, and system administration - on practically all platforms - while remaining the favorite tool for the small daily tasks it was designed for. You might start using Perl because you need it, but you'll continue to use it because you love it. Informed by their years of success at teaching Perl as consultants, the authors have re-engineered the Llama to better match the pace and scope appropriate for readers getting started with Perl, while retaining the detailed discussion, thorough examples, and eclectic wit for which the Llama is famous. The book includes new exercises and solutions so you can practice what you've learned while it's still fresh in your mind. Here are just some of the topics covered: data structures, minimal matching, threading, data parsing, references, objects, modules, and package implementation. If you ask Perl programmers today what book they relied on most when they were learning Perl, you'll find that an overwhelming majority will point to the Llama. With good reason. Other books may teach you to program in Perl, but this book will turn you into a Perl programmer.

《汇编语言程序设计》讲述每种高级语言程序在连接为可执行程序之前，都必须被编译为汇编语言程序，因此对于高级语言程序设计者来说，了解编译器如何生成汇编语言代码十分有用。

《C++程序设计教程》是《C++程序设计教程》的第二版。然而从指导思想、内容结构、写作特点等方面，都以全新的面貌呈现于读者。全书全部重新执笔，代码全部重写，涵盖了基本C++编程方法的全部技术特征。作者在长期的教学、科研实践以及ACM大学生程序设计竞赛培训工作中，总结出了许多难能可贵的教学经验，能使读者快捷而准确地找到编程技术要领，洞穿C++内部实现要害，直击抽象编程本质。与《C++程序设计教程》配套，《C++课程设计指导》、《C++程序设计习题及解答》、《C++程序设计教程详解》和《C++程序设计教程精粹》也将陆续面世。除此之外，还配有C++程序设计教程课件和源代码供读者下载。
