    Perl Debugged By Peter Scott, Ed Wright Publisher : Addison Wesley Pub Date : March 01, 2001 ISBN : 0-201-70054-9 Table of • Pages : 288 Contents "This book was a joy to read. It covered all sorts of techniques for debugging, including 'defensive' paradigms that will eliminate bugs in the first place. As coach of the USA Programming Team, I find the most difficult thing to teach is debugging. This is the first text I've even heard of that attacks the problem. It does a fine job. Please encourage these guys to write more." -Rob Kolstad Perl Debugged provides the expertise and solutions developers require for coding better, faster, and more reliably in Perl. Focusing on debugging, the most vexing aspect of programming in Perl, this example-rich reference and how-to guide minimizes development, troubleshooting, and maintenance time resulting in the creation of elegant and error-free Perl code. Designed for the novice to intermediate software developer, Perl Debugged will save the programmer time and frustration in debugging Perl programs. Based on the authors' extensive experience with the language, this book guides developers through the entire programming process, tackling the benefits, plights, and pitfalls of Perl programming. Beginning with a guided tour of the Perl documentation, the book progresses to debugging, testing, and performance issues, and also devotes a chapter to CGI programming in Perl. Throughout the book, the authors espouse defensible paradigms for improving the accuracy and performance of Perl code. In addition, Perl Debugged includes Scott and Wright's "Perls of Wisdom" which summarize key ideas from each of the chapters, and an appendix containing a comprehensive listing of Perl debugger commands.

With this book you’ll learn by experience while you tackle an exciting series of varied but always practical programming projects. What is an eclectic programmer, you ask? He or she is an inquisitive thinker Practical who likes to play around with new concepts, a person who is project-oriented and enjoys coding, a person who doesn’t mind some technical depth folded in with creative excursions, and a person who is always looking for fresh ideas. This book is a little different from other computer books. It is meant to be entertaining, exciting, and intellectually challenging. Inside you’ll find a collec- tion of diverse projects, ranging from the creative to the practical, written as a nod to all the great Rubyists I’ve been privileged to know. Each chapter dives into Ruby Projects new topics and approaches meant to exercise your programming muscles. You’ll start by building a cross-platform music environment, progress to drawing animations using scalable vector graphics, and then move on to prac- tical problem solving using simulation. In addition, you’ll implement your own turn-based strategy game and build a Mac-native RubyCocoa interface to it.

Perhaps the cooking metaphor is one such, at least in this case. The only problem I have with it is a personal one - I feel a bit like Betty Crocker's mother. The work in question is so monumental that anything I could say here would be either redundant or irrelevant. However, that never stopped me before. Cooking is perhaps the humblest of the arts; but to me humility is a strength, not a weakness.
