Ajax is no longer an experimental approach to website development, but the key to building browser-based applications that form the cornerstone of Web 2.0. Head First Ajax gives you an up-to-date perspective that lets you see exactly what you can do -- and has been done -- with Ajax. With it, you get a highly practical, in-depth, and mature view of what is now a mature development approach.
Using the unique and highly effective visual format that has turned Head First titles into runaway bestsellers, this book offers a big picture overview to introduce Ajax, and then explores the use of individual Ajax components -- including the JavaScript event model, DOM, XML, JSON, and more -- as it progresses. You'll find plenty of sample applications that illustrate the concepts, along with exercises, quizzes, and other interactive features to help you retain what you've learned.
Head First Ajax covers:
The JavaScript event model
Making Ajax requests with XMLHTTPREQUEST objects
The asynchronous application model
The Document Object Model (DOM)
Manipulating the DOM in JavaScript
Controlling the browser with the Browser Object Model
XHTML Forms
POST Requests
XML Syntax and the XML DOM tree
XML Requests & Responses
JSON -- an alternative to XML
Ajax architecture & patterns
The Prototype Library
The book also discusses the server-side implications of building Ajax applications, and uses a "black box" approach to server-side components.
Head First Ajax is the ideal guide for experienced web developers comfortable with scripting -- particularly those who have completed the exercises in Head First JavaScript -- and for experienced programmers in Java, PHP, and C# who want to learn client-side programming.

Objective-C is an exciting and dynamic approach to C-based object-oriented programming; it's the approach adopted by Apple as the foundation for programming under Mac OS X, a Unix-based operating system gaining wide acceptance among programmers and other technologists. Objective-C is easy to learn and has a simple elegance that is a welcome breath of fresh air after the abstruse and confusing C++. To help you master the fundamentals of this language, you'll want to keep the Objective-C Pocket Reference close at hand. This small book contains a wealth of valuable information to speed you over the learning curve. In this pocket reference, author Andrew Duncan provides a quick and concise introduction to Objective-C for the experienced programmer. In addition to covering the essentials of Objective-C syntax, Andrew also covers important faces of the language such as memory management, the Objective-C runtime, dynamic loading, distributed objects, and exception handling.

The book really shines in its code examples: short, clear and to the point; the author repeatedly shows how something can be done in Perl 5 code and how it's expected to work in Perl 6.
— Joseph Brenner, Slashdot Contributor
The author guides you through creating variables and accessing the data in them. You will find out how to save memory by only using the OO variable types when you need them.
— "Mr. Muskrat," Perl Monks
..after reading Scott Walter's gentle overview, I am actually looking forward to Perl 6 - eagerly anticipating rather than dreading its arrival.
— Anthony Lawrence, http://aplawrence.com
Perl 6 Now: The Core Ideas Illustrated with Perl 5 is perfect for those eager to see where Perl is headed, Perl 5 programmers who want to know that their favorite tricks will still work in some form, and programmers wishing to open their minds to advanced programming topics.
Perl 6 generalizes the language, making it more extensible, eliminating longstanding pitfalls, and adding new concepts. Thanks to some clever people and impressive efforts, many of these new features work in Perl 5, so you can start using them now in production-level code.
The book teaches the basics from a Perl 6 perspective, touching on variable interpolation, datastructure use, object construction, threads, closures, symbol tables, and other core features. It then introduces continuations, coroutines, binding (or aliases), hyper operators that work on lists of data at once, set operators that work on complex datatypes, lightweight multidimensional arrays, strong type checking, autoboxing, precompilation, automatic module dependency installation, and more.
Though Perl 6 changes the fundamental syntax in some areas, Perl 5 code isn't left in the lurch. Thanks to PONIE, code from both versions may coexist in a single program. Youll need to adjust only a few habits and learn a few new things, and this early adopters guide will help you do these things.
This book is about taking over Perl code, whether written by someone else or by yourself at an earlier time. Developers regularly estimate that they spend 60 to 80 percent of their time working with existing code. Many problems of code inheritance are common to all languages, but the nature of the language makes Perl especially tricky. The reason why is that Perl is similar to English - bursting with irregular verbs, consistent only when it's convenient, borrowing terms from other languages, and providing many ways to say the same thing. In fact, Perl developers have a motto with the abbreviation TMTOWTDI: There's More Than One Way To Do It. While this flexibility is one of the language's strengths, it also makes it extremely difficult when you are faced with an existing piece of code. There are millions of lines of Perl code being used all over the Web; much of it was built on an ad hoc basis, the creators never imagining that the code would still be in use months or years later. This book will be the resource all Perl programmers need to understand someone else's code, even when it's bad; repair it; convert it to a better style; upgrade it to the latest version of Perl; maintain it; and find and fix its bugs.
Perl ranks among hackers' favorite languages--there's always another approach to a problem, always optimization to be done, and forever new techniques to try. Perl's a hoot. But the culture of tinkering that surrounds Perl has resulted in a large body of hard-to-understand legacy code. That legacy code has to be maintained, extended, and adapted to new conditions--often without the help of the person who originally created it. Perl Medic considers Perl from the perspective of a programmer looking at code written by someone else and trying to answer the ancient question: "What were they thinking?"
It's a creative approach, and one that makes good reading for someone well-versed in Perl programming (author Peter Scott makes the analogy of becoming fluent in a human language, such as French, then studying its various accents and dialects). He shows, for example, a kludgy piece of code that's meant to catch CGI form uploads, then indicates that the obvious replacement is the CGI.pm module. Elsewhere, Scott shows why symbolic references are bad, and how to avoid them by means of hashes. Some of the value in this book is in the form of documentation of the differences among Perl versions; other useful coverage deals with warnings and strictness control as debugging tools. Read this straight through to improve your own code; use the index to help decipher and improve what someone else has written. --David Wall
Topics covered: How to write good Perl code, read bad Perl code, and convert bad Perl code into good in less time that would be required to write an equivalent replacement program from scratch. Testing, debugging, documenting, replacing custom code with CPAN modules, and embracing features that became available in later versions of Perl are all covered. Overall, the author endorses and generally explains the principles of Extreme Programming (XP) for Perl work.

This is a new kind of JavaScript book. It's not cut'n'paste, it's not a reference, and it's not an exhaustive investigation of the JavaScript language. It is about client-side, web focused, and task-oriented JavaScript. JavaScript is a core skill for web professionals, and as every web professional knows, client-side JavaScript can produce all sorts of glitches and bugs. 'Practical JavaScript for the Usable Web' takes a two pronged approach to learning the JavaScript that you need to get your work done: teaching the core client-side JavaScript that you need to incorporate usable interactivity into your web applications, including many short functional scripts, and building up a complete application with shopping cart functionality. When you have finished working with this book, you'll have a thorough grounding in Client-side JavaScript, and be able to construct your own client-side functionality quickly, easily, and without falling into any of the usability traps that this technology leaves wide open.
This book covers: DHTML for IE4 and NN4 browsers, and the Dom for the latest browsers Usability techniques Working scripts that can be incorporated into your web applications immediately Step-by-step breakdown of JavaScript shopping cart functionality Advanced Data Validation Techniques Book Info Covers DHTML for IE4 and NN4 browsers, and the Dom for the latest browsers. Discusses working scripts that can be incorporated into your web applications immediately. Provides advanced data validation techniques.
From the Publisher This is for readers who are either learning JavaScript from scratch, or who have a little experience - perhaps with DreamWeaver behaviors, or incorporating scripts into their pages. It assumes a though understanding of HTML, and a little CSS experience.
