The Ruby Programming Language is the authoritative guide to Ruby and provides comprehensive coverage of versions 1.8 and 1.9 of the language. It was written (and illustrated!) by an all-star team: David Flanagan, bestselling author of programming language "bibles" (including JavaScript: The Definitive Guide and Java in a Nutshell) and committer to the Ruby Subversion repository. Yukihiro "Matz" Matsumoto, creator, designer and lead developer of Ruby and author of Ruby in a Nutshell, which has been expanded and revised to become this book. why the lucky stiff, artist and Ruby programmer extraordinaire. This book begins with a quick-start tutorial to the language, and then explains the language in detail from the bottom up: from lexical and syntactic structure to datatypes to expressions and statements and on through methods, blocks, lambdas, closures, classes and modules. The book also includes a long and thorough introduction to the rich API of the Ruby platform, demonstrating -- with heavily-commented example code -- Ruby's facilities for text processing, numeric manipulation, collections, input/output, networking, and concurrency. An entire chapter is devoted to Ruby's metaprogramming capabilities. The Ruby Programming Language documents the Ruby language definitively but without the formality of a language specification. It is written for experienced programmers who are new to Ruby, and for current Ruby programmers who want to challenge their understanding and increase their mastery of the language.

JavaScript ist eine mächtige, objektorientierte Skriptsprache, deren Code in HTML-Seiten eingebettet und vom Browser interpretiert und ausgeführt wird. Richtig eingesetzt, eignet sie sich aber auch für die Programmierung komplexer Anwendungen und hat im Zusammenhang mit HTML5 noch einmal an Bedeutung gewonnen. Diese Kurzreferenz ist ein Auszug aus der überarbeiteten und ergänzten Neuauflage von JavaScript – Das umfassende Referenzwerk, 6. Auflage, der JavaScript-Bibel schlechthin. JavaScript kurz & gut befasst sich in den ersten neun Kapiteln mit der neuesten Version des Sprachkerns (ECMAScript 5) und behandelt die Syntax der Sprache, Typen, Werte, Variablen, Operatoren und Anweisungen sowie Objekte, Arrays, Funktionen und Klassen. All dies ist nicht nur für die Verwendung von JavaScript in Webbrowsern, sondern auch beim Einsatz von Node auf der Serverseite relevant. In den folgenden fünf Kapiteln geht es um die Host-Umgebung des Webbrowsers. Es wird erklärt, wie Sie clientseitiges JavaScript für die Erstellung dynamischer Webseiten und -applikationen verwenden und mit JavaScript auf die HTML5-APIs zugreifen. Diese Kapitel liefern Informationen zu den wichtigsten Elementen von clientseitigem JavaScript: Fenster, Dokumente, Elemente, Stile, Events, Netzwerke und Speicherung.

Rails is a robust, flexible development platform that lets you build complex websites quickly. Major websites like GitHub, Hulu, and Twitter have run Rails under the hood, and if you know just enough HTML and CSS to be dangerous, Rails Crash Course will teach you to harness Rails for your own projects and create web applications that are fast, stable, and secure. In Part I, you’ll learn Ruby and Rails fundamentals and then dive straight into models, controllers, views, and deployment. As you work through the basics, you’ll learn how to: * Craft persistent models with Active Record * Build view templates with Embedded Ruby * Use Git to roll back to previous versions of your code base * Deploy applications to Heroku In Part II, you’ll take your skills to the next level as you build a social networking app with more advanced Ruby tools, such as modules and metaprogramming, and advanced data modeling techniques within Rails’s Active Record. You’ll learn how to: * Implement an authentication system to identify authorized users * Write your own automated tests and refactor your code with confidence * Maximize performance with the asset pipeline and turbolinks * Secure your app against SQL injection and cross-site scripting * Set up a server and deploy applications with Capistrano Each chapter is packed with hands-on examples and exercises to reinforce what you’ve learned. Whether you’re completely new to Ruby or you’ve been mucking around for a bit, Rails Crash Course will take you from the basics to shipping your first Rails application, fast.

While most books written about Rails cater to programmers looking for information on data structures, Learning Rails targets web developers whose programming experience is tied directly to the Web. Rather than begin with the inner layers of a Rails web application--the models and controllers--this unique book approaches Rails development from the outer layer: the application interface. You'll learn how to create something visible with Rails before reaching the more difficult database models and controller code. With Learning Rails, you can start from the foundations of web design you already know, and then move more deeply into Ruby, objects, and database structures. This book will help you: Present web content by building an application with a basic view and a simple controller, while learning Ruby along the way Build forms and process their results, progressing from the simple to the more complex Connect forms to models by setting up a database, and use Rails' ActiveRecord to create code that maps to database structures Use Rails scaffolding to build applications from a view-centric perspective Add common web application elements such as sessions, cookies, and authentication Build applications that combine data from multiple tables Create simple but dynamic interfaces with Rails and Ajax Once you complete Learning Rails, you'll be comfortable working with the Rails web framework, and you'll be well on your way to becoming a Rails guru.

This PDF will show you how your small business or enterprise can publish its APIs (application programming interface) to a developer community just like the behemoths of the Internet--Google, Yahoo!, eBay, and Amazon. These giants already offer their APIs to other programmers and allow for add-on services and mash-ups to develop from them--but until recently, the capability for most enterprises to do the same was limited by a myriad of competing standards and a lack of easy-to-use tools to accomplish the task. Ruby on Rails levels the playing field for companies by simplifying the process of building web services and documenting APIs. Now with Rails, enterprise-quality tools are available for all developers. In this document, we'll look at how Ruby on Rails makes building web service clients and servers simple and fun. Along the way, we'll give working examples and code details so you can see just how everything works.

Founders at Work recounts the early struggles for independence and acceptance of many of modern technology’s giants, through personal interviews that are at times hilarious, at times painful, and always inspiring. As human-interest stories they will interest the same audience that enjoys reading about the Google founders in PEOPLE magazine. These stories are exceptionally interesting, because they're about the early stages, when the founders were younger and inexperienced. Most readers know startup founders only as confident millionaires. As novices trying to find their way by trial and error, they're more human, and easier for the reader to identify with.
