Network Programming with Perl

"Network programming"--the term had a distinct meaning once, but now it begs the question, "Is there another kind?" That's why Lincoln Stein's Network Programming with Perl is valuable. It shows how one of the world's top Perl authorities brings the language to bear on problems that require communication among computers, showing that you may not have to resort to Java as soon as you may have thought to meet a networking requirement. What's more, Stein doesn't assume you have a lot of Perl expertise. An intermediate-level familiarity with the language should enable you to understand the examples in the book and follow its classic code-and-commentary structure.

Stein presents full, working scripts, calling attention to particularly interesting lines and passages by repeating them in the text. If a program makes use of an unusual or previously undiscussed function (and lots of them do, because one of the author's missions is to introduce the contents of specialized libraries), its syntax and legal parameters will be documented and a concise statement of its behavior provided. The example programs are the best part of this book, though. As the problems get more complicated, it's fun to watch Stein solve them with efficient, attractive code. Unless you're a really experienced professional, you'll be able to study the examples in this book and learn a lot. --David Wall
