Perl/Tk is the marriage of the Tk graphical toolkit with Perl, the powerful programming language used primarily for system administration, web programming, and database manipulation. With Perl/Tk, you can build Perl programs with an attractive, intuitive GUI interface with all the power of Perl behind it. Mastering Perl/Tk is the "bible" of Perl/Tk: It's not only a great book for getting started, but the best reference for learning the techniques of experienced Perl/Tk programmers. The first half of the book contains the basics on how to use Perl/Tk, and then branches out into advanced applications with a series of extensive program examples. The result is a book accessible for novices, and invaluable for experienced programmers ready to learn the next step in the elegant and effective use of Perl/Tk.

Written for web developers with basic Perl skills, this book guides new users through the open-source Perl-based Model-View-Controller Catalyst framework using real-world examples and systematic code snippets, covering application design, development, testing, and deployment. If you are excited by Ruby on Rails but prefer the familiarity of Perl, get this book and get started. The way that many web applications are implemented makes development painful and repetitive. Catalyst solves this problem, organizing your web application to design and implement it in a natural, maintainable, and testable way. Its philosophies are Do It Yourself and Don't Repeat Yourself. Everything is written only once; database access and configuration are centralized; you just write actions for each URL in your application and Catalyst handles the details. Catalyst is designed to be reliable; the code is well tested; there are hundreds of production applications, thousands of users, and a thriving community.

This book is intended for anyone who has an interest in useful Perl scripting, in particular on the Windows platform, for the purpose of incident response, and forensic analysis, and application monitoring. While a thorough grounding in scripting languages (or in Perl specifically) is not required, it is helpful in fully and more completely understanding the material and code presented in this book. This book contains information that is useful to consultants who perform incident response and computer forensics, specifically as those activities pertain to MS Windows systems (Windows 2000, XP, 2003, and some Vista). My hope is that not only will consultants (such as myself) find this material valuable, but so will system administrators, law enforcement officers, and students in undergraduate and graduate programs focusing on computer forensics.

Regular expressions, a powerful tool for manipulating text and data, are found in scripting languages, editors, programming environments, and specialized tools. In this book, author Jeffrey Friedl leads you through the steps of crafting a regular expression that gets the job done. He examines a variety of tools and uses them in an extensive array of examples, with a major focus on Perl. 

Regular expressions are a powerful tool for manipulating text and data. If you don't use them yet, you will discover in this book a whole new world of mastery over your data. If you already use them, you'll appreciate this book's unprecedented detail and breadth of coverage. If you think you know all you need to know about regular expressions, this book is a stunning eye-opener. With regular expressions, you can save yourself time and aggravation while dealing with documents, mail messages, log files — you name it — any type of text or data. For example, regular expressions can play a vital role in constructing a World Wide Web CGI script, which can involve text and data of all sorts. Regular expressions are not a tool in and of themselves, but are included as part of a larger utility. The classic example is grep. These days, regular expressions can be found everywhere, such as in:

• Scripting languages (including Perl, Tcl, awk, and Python)
• Editors (including Emacs, vi, and Nisus Writer)
• Programming environments (including Delphi and Visual C++)
