    Kurzfassung: The Perl Journal ( TPJ ) did something most print journals aspire to, but few succeed. Within a remarkable short time, TPJ acquired a cult-following and became the voice of the Perl community. Every serious Perl programmer subscribed to it, and every notable Perl guru jumped at the opportunity to write for it. Back issues were swapped like trading cards. No longer in print format, TPJ remains the quintessential spirit of Perl--a publication for and by Perl programmers who see fun and beauty in an admittedly quirky little language. Games, Diversions, and Perl Culture is the third volume of The Best of the Perl Journal , compiled and re-edited by the original editor and publisher of The Perl Journal , Jon Orwant. In this series, we've taken the very best (and still relevant) articles published in TPJ over its 5 years of publication and immortalized them into three volumes.The 47 articles included in this volume are simply some of the best Perl articles ever written on the subjects of games, diversions, and the unique culture of this close-knit community, by some of the best Perl authors and coders. Games, Diversions & Perl Culture focuses on entertaining topics that make Perl users such fanatics about the language. You'll find all of the playful features TPJ offered over the years, including the Obfuscated Perl Contests, Perl Quiz Shows, humor articles, and renowned one-line recipes. The book also contains a panoply of quirky applications of Perl, including genetic algorithms, home automation, music programming, and an entire section on natural language processing.This anthology is an unmatched compendium of Perl lore.

    Kurzfassung: In its first five years of existence, The Perl Journal (TPJ) became the voice of the Perl community. Every serious Perl programmer subscribed to it, and every notable Perl guru jumped at the opportunity to write for it. TPJ explained critical Perl topics and demonstrated Perl's utility for fields as diverse as astronomy, biology, economics, AI, and games. Back issues were hoarded, or swapped like trading cards. No longer in print format, The Perl Journal remains a proud and timeless achievement of Perl during one of its most exciting periods of development. Web, Graphics & Perl/Tk is the second volume of The Best of the Perl Journal , compiled and re-edited by the original editor and publisher of The Perl Journal , Jon Orwant. In this series, we've taken the very best (and still relevant) articles published in TPJ over its five years of publication and immortalized them into three volumes. The forty articles included in this volume are simply some of the best Perl articles ever written on the subjects of graphics, the Web, and Perl/Tk, by some of the best Perl authors and coders. Much of Perl's success is due to its capabilities for developing web sites; the Web section covers popular topics such as CGI programs, mod_perl, spidering, HTML parsing, security, and content management. The Graphics section is a grab bag of techniques, ranging from simple graph generation to ray tracing and real-time video digitizing. The Perl/Tk section shows you how to use the popular Perl/Tk toolkit for developing graphical applications that work on both Unix/Linux and Windows without a single change. Written by twenty-three of the most prominent and prolific members of the closely-knit Perl community, including Lincoln Stein, Mark-Jason Dominus, Alligator Descartes, and Dan Brian, this anthology does what no other book can, giving unique insight into the real-life applications and powerful techniques made possible by Perl.

    Kurzfassung: Many programmers would love to use Perl for projects that involve heavy lifting, but miss the many traditional algorithms that textbooks teach for other languages. Computer scientists have identified many techniques that a wide range of programs need, such as: Fuzzy pattern matching for text (identify misspellings!) Finding correlations in data Game-playing algorithms Predicting phenomena such as Web traffic Polynomial and spline fitting Using algorithms explained in this book, you too can carry out traditional programming tasks in a high-powered, efficient, easy-to-maintain manner with Perl.This book assumes a basic understanding of Perl syntax and functions, but not necessarily any background in computer science. The authors explain in a readable fashion the reasons for using various classic programming techniques, the kind of applications that use them, and -- most important -- how to code these algorithms in Perl.If you are an amateur programmer, this book will fill you in on the essential algorithms you need to solve problems like an expert. If you have already learned algorithms in other languages, you will be surprised at how much different (and often easier) it is to implement them in Perl. And yes, the book even has the obligatory fractal display program.There have been dozens of books on programming algorithms, some of them excellent, but never before has there been one that uses Perl. The authors include the editor of The Perl Journal and master librarian of CPAN; all are contributors to CPAN and have archived much of the code in this book there. "This book was so exciting I lost sleep reading it." Tom Christiansen

    Kurzfassung: From access counters and log-report graphs to scientific plots and on-the-fly animated GIFs, graphics scripting is within the grasp of most Web authors. It is a little documented field, however, and the many valuable free libraries and tools available on the Internet remain under-utilized. Programming Web Graphics with Perl & GNU Software is aimed at intermediate and advanced Web users who want to use CGI scripts to generate dynamic graphic content. It will also help to demystify the manipulation of graphics formats for newcomers to the Web. Programming Web Graphics with Perl & GNU Software takes a practical, resource-like approach to the content. It is not a book about design or aesthetics of Web graphics; its focus is on programming or, more accurately, scripting programs that manipulate graphics file to be published on the Web. Most of the examples in the book use Perl as a scripting language, though the concepts are applicable to any programming language. However, several powerful Perl modules for generating graphics (GD, PerlMagick, GIFgraph) should help position Perl as a major contender for your Web graphics applications. Most of the topics covered in the book are applicable to any platform (NT, Linux, Un*x, MaxOS), with the exception of the chapter detailing the Gnu Image Manipulation Program (a free Adobe Photoshop-like application), which requires a connection to an X server. The focus is always on free software, when it is available. This book covers the following: a tour through the most popular Web graphics file formats by implementing parsers for GIF, JPEG, and PNG files descriptions of the PNG, JPEG, and giflib libraries, as well as many other free and proprietary libraries and SDKs extensive documentation and examples using the Perl graphics modules GD and GIFgraph, and the Perl interface to the powerful ImageMagick libraries documentation on the Gnu Image Manipulation Program (GIMP) and the Perl interface that lets you easily script plug-ins or interface to the GIMP via the Web the creation of image maps from data extracted from a database the implementation of several new Perl modules for the creation of neatly formatted PostScript files details on interfacing to a fax gateway reusable recipes for many popular applications such as Web counters and Web cams the creation of animated GIFs on-the-fly One of the key ingredients to the success of the Web is that anyone who wanted to could participate in publishing to the wo...

    Kurzfassung: Learning Perl/Tk is a tutorial for Perl/Tk, the extension to Perl for creating graphical user interfaces. With Tk, Perl programs can be window-based rather than command-line based, with buttons, entry fields, listboxes, menus, and scrollbars. Originally developed for the Tcl language, the Perl port of the Tk toolkit liberates Perl programmers from the world of command-line options, STDIN, and STDOUT, allowing them to build graphical, event-driven applications for both Windows and UNIX. This book is aimed at Perl novices and experts alike. It explains the reasoning behind event-driven applications and drills in guidelines on how to best design graphical applications. It teaches how to implement and configure each of the Perl/Tk graphical elements step-by-step. Special attention is given to the geometry managers, which are needed to position each button, menu, label and listbox in the window frame. Although this book does not teach basic Perl, anyone who has written even the simplest Perl program should be able to learn Tk from this book. The writing is breezy and informal, and gets right to the point of what you need to know and why. The book is rife with illustrations that demonstrate how each element is drawn and how its configuration options affect its presentation. Learning Perl/Tk is for every Perl programmer who would like to implement simple, easy-to-use graphical interfaces.
