    Abstract: 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

    Abstract: 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...

    Keywords: Tk toolkit ; Perl (Computer program language) ; Electronic books ; local
    Abstract: 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.

    Keywords: Electronic mail systems ; Internet programming ; Electronic books ; local
    Abstract: The Internet's "killer app" is not the World Wide Web or Push technologies: it is humble electronic mail. More people use email than any other Internet application. As the number of email users swells, and as email takes on an ever greater role in personal and business communication, Internet mail protocols have become not just an enabling technology for messaging, but a programming interface on top of which core applications are built. Programming Internet Email unmasks the Internet Mail System and shows how a loose federation of connected networks have combined to form the world's largest and most heavily trafficked message system. Programming Internet Email tames the Internet's most popular messaging service. For programmers building applications on top of email capabilities, and power users trying to get under the hood of their own email systems, Programming Internet Email stands out as an essential guide and reference book. In typical O'Reilly fashion, Programming Internet Email covers the topic with nineteen tightly written chapters and five useful appendixes.Following a thorough introduction to the Internet Mail System, the book is divided into five parts: Part I covers email formats, from basic text messages to the guts of MIME. Secure email message formats (OpenPGP and S/MIME), mailbox formats and other commonly used formats are detailed in this reference section. Part II describes Internet email protocols: SMTP and ESMTP, POP3 and IMAP4. Each protocol is covered in detail to expose the Internet Mail System's inner workings. Part III provides a solid API reference for programmers working in Perl and Java. Class references are given for commonly used Perl modules that relate to email and the Java Mail API. Part IV provides clear and concise examples of how to incorporate email capabilities into your applications. Examples are given in both Perl and Java. Part V covers the future of email on the Internet. Means and methods for controlling spam email and newly proposed Internet mail protocols are discussed. Appendixes to Programming Internet Email provide a host of explanatory information and useful references for the programmer and avid user alike, including a comprehensive list of Internet RFCs relating to email, MIME types and a list of email related URLs. Programming Internet Email will answer all of your questions about mail and extend your abilities into this most popular messaging frontier.

    Abstract: The Swing classes eliminate Java's biggest weakness: its relatively primitive user interface toolkit. Swing provides many new components and containers that allow you to build sophisticated user interfaces, far beyond what was possible with AWT. The old components have been greatly improved, and there are many new components, like trees, tables, and even text editors. It also adds several completely new features to Java's user interface capabilities: drag-and-drop, undo, and the ability to develop your own "look and feel," or the ability to choose between several standard looks. The Swing components are all "lightweight," and therefore provide more uniform behavior across platforms, making it easier to test your software. All these new features mean that there's a lot to learn. Swing is undoubtedly way ahead of AWT -- or, for that matter, any widely available user interface toolkit -- but it's also a lot more complicated. It's still easy to do simple things. But once you've seen what's possible, you won't want to do the simple things. Java Swing gives you in-depth coverage of everything you need to know to take full advantage of Swing, providing detailed descriptions of every class and interface in the key Swing packages. It shows you how to use all of the new components, allowing you to build state-of-the-art user interfaces. It also discusses how the components implement the MVC (Model View Controller) architecture, so you can understand how the components are designed and subclass them intelligently. Finally, it shows how to create your own "look and feel." Throughout, Java Swing focuses on giving you the context you need to understand what you're doing. It's more than documentation; Java Swing helps you develop code quickly and effectively. Whether you're a serious Java developer, or just trying to find out what Java can do, you'll find Java Swing an indispensable guide.

    Keywords: Lingo (Computer program language) ; Electronic books ; local
    Abstract: Macromedia Director 6 is the premiere authoring tool for delivering interactive content on both the Internet and the desktop. It is the dominant multimedia package for Windows 95/NT, Windows 3.1, and the Macintosh. A quarter million developers use Director(R) to incorporate animation and audio into dynamic Web pages, and to create engaging interactive corporate presentations, multimedia advertising, entertainment CD-ROMs, Enhanced music CDs, and even DVDs. Lingo is Director's powerful scripting language. This companion book to Director in a Nutshell is an essential tool for both new and experienced Lingo programmers seeking a deeper knowledge of the language. Bruce Epstein is the author of both these books and brings years of hands-on experience with Director and Lingo. The book includes numerous useful Lingo examples. Exhaustively tested, this book corrects many errors found in Macromedia's Lingo documentation and repeated verbatim in most third-party books. Extremely comprehensive, this book details dozens of misdocumented and undocumented Lingo keywords that are omitted from Macromedia's manuals and third-party books. Lingo in a Nutshell caters to the huge pool of Director users attempting to bridge the Lingo gap, yet provides the details for the experienced Linguist that are lacking in other Lingo books. In typical nutshell style (clear, concise, deep and narrow) this book explores the syntax, structure and commands of the Lingo language. The detailed chapters describe messages, events, scripts, handlers, variables, lists, file I/O, Behaviors, child objects, Xtras, and more. This book teaches you to troubleshoot and debug common Lingo errors. Lingo in a Nutshell is the book for which both Director users and power Lingo programmers have been yearning. The book extensively covers topics not found in other Lingo books: Cross-platform Lingo differences Lingo internals for experienced programmers Events, messages, and scripts Timers, tempos, cue points, and synchronization Data types and expressions Math, numerical expressions, geometry, and trigonometry Coordinates, alignment, and registration point Lingo in a Nutshell is the most concise and compete guide available. It is a high-end handbook at a low-end price. An essential desktop reference for every Director user.

    Keywords: Cryptography ; Java (Computer program language) ; Electronic books ; local
    Abstract: Cryptography, the science of secret writing, is the biggest, baddest security tool in the application programmer's arsenal. Cryptography provides three services that are crucial in secure programming. These include a cryptographic cipher that protects the secrecy of your data; cryptographic certificates, which prove identity (authentication); and digital signatures, which ensure your data has not been damaged or tampered with.This book covers cryptographic programming in Java. Java 1.1 and Java 1.2 provide extensive support for cryptography with an elegant architecture, the Java Cryptography Architecture (JCA). Another set of classes, the Java Cryptography Extension (JCE), provides additional cryptographic functionality. This book covers the JCA and the JCE from top to bottom, describing the use of the cryptographic classes as well as their innards.The book is designed for moderately experienced Java programmers who want to learn how to build cryptography into their applications. No prior knowledge of cryptography is assumed. The book is peppered with useful examples, ranging from simple demonstrations in the first chapter to full-blown applications in later chapters.Topics include: The Java Cryptography Architecture (JCA) The Java Cryptography Extension (JCE) Cryptographic providers The Sun key management tools Message digests, digital signatures, and certificates (X509v3) Block and stream ciphers Implementations of the ElGamal signature and cipher algorithms A network talk application that encrypts all data sent over the network An email application that encrypts its messages Covers JDK 1.2 and JCE 1.2.

    Keywords: Expect ; Interactive computer systems ; Tcl (Computer program language) ; Electronic books ; local
    Abstract: Expect is quickly becoming a part of every UNIX user's toolbox. It allows you to automate Telnet, FTP, passwd, rlogin, and hundreds of other applications that normally require human interaction. Using Expect to automate these applications will allow you to speed up tasks and, in many cases, solve new problems that you never would have even considered before.For example, you can use Expect to test interactive programs with no changes to their interfaces. Or wrap interactive programs with Motif-like front-ends to control applications by buttons, scrollbars, and other graphic elements with no recompilation of the original programs. You don't even need the source code! Expect works with remote applications, too. Use it to tie together Internet applications including Telnet, Archie, FTP, Gopher, and Mosaic.Don Libes is the creator of Expect as well as the author of this book. In Exploring Expect , he provides a comprehensive tutorial on all of Expect's features, allowing you to put it immediately to work on your problems. In a down-to-earth and humorous style, he provides numerous examples of challenging real-world applications and how they can be automated using Expect to save you time and money.Expect is the first of a new breed of programs based on Tcl, the Tool Command Language that is rocking the computer science community. This book provides an introduction to Tcl and describes how Expect applies Tcl's power to the new field of interaction automation. Whether your interest is in Expect or interaction automation or you simply want to learn about Tcl and see how it has been used in real software, you will find Exploring Expect a treasure trove of easy-to-understand and valuable information.
