Content Description

《Perl高效编程(第2版)》是Perl 编程领域的“圣经级”著作。它提供了一百多个详实的应用案例,足以涵盖编程过程中经常遇到的方方面面,由此详细阐释出各种高效且简洁的写法。
《Perl高效编程(第2版)》第1 版曾畅销十年之久,而在第2 版中不仅修正了前版存在的一些问题,更与时俱进地引入了许多Perl 领域的新主题,使内容更加完善丰富,也更具实用性。
Author Description

Joseph N. Hall 一个自学成才的“电脑神童”,靠着玩TI公司的可编程计算器和带4KB内存的Radio Shack TRS-80 Model 1出道。他从14岁起就开始教别人用电脑,早在1984年就开始了职业编程生涯。他开始接触Unix和C语言是1987年,接触Perl则是1993年。

Joshua A. McAdams一直以在谷歌工作为荣。作为最近五年来非常活跃的Perl社区成员,他是Perlcast(www.perlcast.com)的创办者,主持了两届芝加哥YAPC::NA,同时也是Chicago.pm的召集人,他在全球的Perl会议上发表了不少演讲,另外,他还是一名CPAN的作者,并持续为The Perl Review和Perl Advent Calendar供稿。

brian d foy 《Perl语言入门(第5版)》以及Intermediate Perl的合著者,也是《精通Perl》的作者。他发起了第一个Perl用户组——New York Perl Mongers;作为The Perl Review的出版人,还维护着一部分Perl核心文档。另外,他也是一名Perl讲师,常常在聚会上发言。

盛春大二开始自学Perl编程,在通读完《Perl 5详解》后利用暑期打工的机会,专职于Perl语言的CGI开发。毕业后的工作也一直以Perl语言作为主要开发工具,目前就职于思科IronPort的邮件及Web安全部门,负责中文反垃圾邮件规则的开发和维护以及内部工具和报告的开发。早年曾为PerlChina筹建社区站点,翻译过数篇技术文章。2007年和蒋永清合作翻译《Perl Testing程序高手秘笈》,2009年与蒋永清、王晖合作翻译《Perl 语言入门(第5版)》,2010年再度合作,翻译了即将出版的《使用Perl实现系统管理自动化》以及这本《Perl高效编程》。此外,在2009年还主持翻译了开源图书《Pro Git》。

王晖《Perl 语言入门(第5版)》及《使用Perl实现系统管理自动化》的合译者。接触到Perl是在2000年,很快喜欢上了这门语言和它的社区,熟悉Linux/ Unix,在盛春的影响下成为Mac用户,目前和盛春一样服务于IronPort 的邮件及Web安全部门,大部分工作都是在FreeBSD下使用Perl来完成的,包括数据分析、采集、系统管理及Web应用等。希望国内能有更多的Perl爱好者及基于Perl的应用出现。

张东亮2004年接触并喜欢上了Perl,对正则表达式相逢恨晚。建有个人博客“我爱正则表达式”,专用来记录Perl等脚本语言中正则表达式的学习心得和应用技巧。目前服务于IronPort的邮件及Web安全部门,负责维护反垃圾邮件/反病毒系统和内部网络的建设。


蒋永清1997年在一台收银机上开始了Linux的自学,2002年夏开始接触 Perl编程,2003年开始参与PerlChina技术论坛。2004年至2009年完成了数十篇技术文章和两本Perl书籍的翻译。2010年起在北京从事互联网维护工作,随后翻译完成了另外两本Perl书籍。目前和家人、孩子、朋友一起在北京生活。
