Perhaps you've taken on a larger project than the ones you're used to. Or you want to add a user interface or a networking component. Or you need to do more complicated error trapping.Whether your knowledge of Perl is casual or deep, this book will make you a more accomplished programmer. Here you can learn the complex techniques for production-ready Perl programs. This book explains methods for manipulating data and objects that may have looked like magic before. Furthermore, it sets Perl in the context of a larger environment, giving you the background you need for dealing with networks, databases, and GUIs. The discussion of internals helps you program more efficiently and embed Perl within C or C within Perl.Major topics covered include:Practical use of packages and classes (object-oriented programming) Complex data structures Persistence (e.g., using a database) Networking Graphical interfaces, using the Tk toolkit Interaction with C language functions Embedding and extending the Perl interpreterIn addition, the book patiently explains all sorts of language details you've always wanted to know more about, such as the use of references, trapping errors through the eval operator, non-blocking I/O, when closures are helpful, and using ties to trigger actions when data is accessed. You will emerge from this book a better hacker, and a proud master of Perl.

    Actually, it's computer sense--C programming. After digesting C For Dummies, 2nd Edition, you'll understand it. C programs are fast, concise and versatile. They let you boss your computer around for a change. So turn on your computer, get a free compiler and editor (the book tells you where), pull up a chair, and get going. You won't have to go far (page 13) to find your first program example. You'll do short, totally manageable, hands-on exercises to help you make sense of:All 32 keywords in the C language (that's right--just 32 words) The functions--several dozen of them Terms like printf(), scanf(), gets (), and puts () String variables, numeric variables, and constants Looping and implementation Floating-point values In case those terms are almost as intimidating as the idea of programming, be reassured that C For Dummies was written by Dan Gookin, bestselling author of DOS For Dummies, the book that started the whole library. So instead of using expletives and getting headaches, you'll be using newly acquired skills and getting occasional chuckles as you discover how to:Design and develop programs Add comments (like post-it-notes to yourself) as you go Link code to create executable programs Debug and deploy your programs Use lint, a common tool to examine and optimize your code A helpful, tear-out cheat sheet is a quick reference for comparison symbols, conversion characters, mathematical doodads, C numeric data types, and more. C For Dummies takes the mystery out of programming and gets you into it quickly and painlessly.

    Restructured into six parts, this new edition covers a wide spectrum of software processes from initial requirements solicitation through design and development.

    Sipser's candid, crystal-clear style allows students at every level to understand and enjoy this field. His innovative "proof idea" sections explain profound concepts in plain English. The new edition incorporates many improvements students and professors have suggested over the years, and offers updated, classroom-tested problem sets at the end of each chapter.

    Includes many useful applications.

    PHP is a server-side, HTML-embedded scripting language. It is an open source technology, rapidly gaining popularity as a scripting language for people running dynamic websites. One of its major attractions over Perl, JavaScript and other scripting languages is that PHP has a built-in database integration layer and seamless IP connectivity, with LDAP and TCP as well as the IMAP mail interface. Features; Real world, practical experience and techniques From installation and configuration of the PHP engine to advanced dynamic application design Definitive coverage of core PHP language and database addressing: MySQL is covered in depth. Practical e-commerce and business scripting including database application development, together with PHP and XML applications. LDAP connectivity addressed.

    The aim of The Node Beginner Book is to get you started with developing applications for Node.js, teaching you everything you need to know about advanced JavaScript along the way on 59 pages.

    The proven success of database design treatment is sustained and further improved in this revision. The proven Parts organizations streamline the chapter coverage, so it is an ideal choice for your classroom. Each Part opens with a new business vignette, which provides real world examples to engage your students. The new edition includes updates in every chapter as well as added exercises and cases. There are new chapters such as Advanced Modeling Concepts, Database Performance Tuning and Query Optimization, and Database Connectivity and Web Development. In the seventh edition you will find examples of database usage, which highlights eBAY for compelling context. In our new Query Optimization chapter, we cover database performance tuning concepts, index selectivity and SQL coding practices. There is added EERD coverage such as clusters and subtype discriminator attributes. With the authors' strong writing style and outstanding balance of theory and practice, this is just a small sampling of the improvements we have made to the new edition of Database Systems: Design, Implementation, and Management by Peter Rob and Carlos Coronel.

    sed, awk, and regular expressions allow programmers and system administrators to automate editing tasks that need to be performed on one or more files, to simplify the task of performing the same edits on multiple files, and to write conversion programs.The sed & awk Pocket Reference is a companion volume to sed & awk, Second Edition, Unix in a Nutshell, Third Edition, and Effective awk Programming, Third Edition.

    You need to stay current on the relevant Web specifications, like HTML, CSS, DOM, and ECMAScript. You also need to know how the latest Web browsers from Netscape and Microsoft actually implement these standards, since browser implementations of the standards are less than perfect. Right now, you're forced to keep multiple reference books open on your desk (or multiple browser windows open on your screen), just to develop a simple dynamic Web page that works properly under both Navigator and Internet Explorer.Dynamic HTML: The Definitive Reference changes all that. This book is an indispensable compendium for Web content developers. It contains everything you need to create functional cross-platform Web applications, including:A complete reference for all of the HTML tags, CSS style attributes, browser document objects, and JavaScript objects supported by the various standards and the latest versions of Navigator and Internet Explorer. Browser compatibility is emphasized throughout; the reference pages clearly indicate browser support for every entity. Handy cross-reference indexes that make it easy to find interrelated HTML tags, style attributes, and document objects. An advanced introduction to creating dynamic Web content that addresses the cross-platform compromises inherent in Web page design today. If you have some experience with basic Web page creation, but are new to the world of dynamic content, Dynamic HTML: The Definitive Reference will jump-start your development efforts. If you are an experienced Web programmer, you'll find the browser-compatibility information invaluable. This book is the only DHTML reference that a Web developer needs.Dynamic HTML: The Definitive Reference is designed to work in conjunction with HTML: The Definitive Guide and JavaScript: The Definitive Guide. HTML: The Definitive Guide teaches you about every element of HTML in detail, with explanations of how each element works and how it interacts with other elements, as well as numerous examples. JavaScript: The Definitive Guide provides a thorough description of the JavaScript language, complete with sophisticated examples that show you how to handle common Web application tasks. Together, these three books provide a complete library for Web content developers.
