Written for novice to intermediate Rails developers, Rails Recipes: Rails 3 Edition is packed with solutions to 70 of the most vexing problems you’re likely to face on the job. From building custom forms and powering pages with JQuery to integrating with legacy databases, it’s all here. Each recipe has been updated to reflect the latest features of Rails 3.1 and each lays out a distinctive solution to a problem you may be facing today or could well encounter tomorrow. In addition, you’ll find half the book is stocked with new eye-opening solutions to such common problems as how to extend Rails, test and deploy your sites, or add a web service to your actions. And each recipe not only lays out a succinct solution, but explains its rationale and the technologies that make it work.

Loaded with the insights of a Rails community leader, members of the Rails core team and other experts, this is the book you’ll want to have at your side as you craft your next project.

Book Description

Working in the View layer requires a breadth of knowledge and attention to detail unlike anywhere else in Rails. One wrong move can result in brittle, complex views that stop future development in its tracks. This book will help you break free from tangles of logic and markup in your views as you pick up the practical skills you need to implement your user interface cleanly and maintainably.

You’ll discover how to build up solid, sustainable layouts and popular interface elements with semantic HTML5 and CSS3, and when you can responsibly generate markup and use advanced presenters… all without leaving the designers on your team out in the cold. Widen your appeal with responsive design, and discover how new progressive enhancement techniques can take you beyond the “weakest link” approach of the past. Master the asset pipeline introduced in Rails 3.1 and use Sass and Coffeescript to make your interface code shorter and more enjoyable.

You’ll create elegant, well-structured views that are a joy to build on. You’ll appreciate its comprehensive, objective guidance in a realm full of subjective opinions.

What You Need:
All examples in the book assume Rails 3.1 or later and Ruby 1.9.x are installed. Detailed information on how to install these for Windows, Mac OS X and Linux is included in the book.

Book Description

Learn from legendary Japanese Ruby hacker Masatoshi Seki in this first English-language book on his own Distributed Ruby library. You’ll find out about distributed computing, advanced Ruby concepts and techniques, and the philosophy of the Ruby way—straight from the source.

dRuby has been part of the Ruby standard library for more than a decade, yet few know the true power of the gem. Completely written in Ruby, dRuby enables you to communicate between distributed Ruby processes as if there were no boundaries between processes. This is one of the few books that covers distributed and parallel programming for Ruby developers.

The dRuby Book has been completely updated and expanded from its Japanese version, with three new chapters written by Masatoshi-san. You’ll find out about the design concepts of the dRuby library, and walk through step-by-step tutorial examples. By building various distributed applications, you’ll master distributed programming as well as advanced Ruby techniques such as multithreading, object references, garbage collection, and security. Then you’ll graduate to advanced techniques for using dRuby with Masatoshi-san’s other libraries, such as eRuby and Rinda—the Ruby version of the Linda distributed tuplespace system. In the three new chapters, you’ll see how to integrate dRuby and eRuby, get a thorough grounding in parallel programming concepts with Rinda, and create a full text search system using Drip.

Step by step, you’ll gain mastery of dRuby and distributed computing. Download Now »

Book Description

Creating robust software requires the use of efficient algorithms, but programmers seldom think about them until a problem occurs. Algorithms in a Nutshell describes a large number of existing algorithms for solving a variety of problems, and helps you select and implement the right algorithm for your needs — with just enough math to let you understand and analyze algorithm performance.

With its focus on application, rather than theory, this book provides efficient code solutions in several programming languages that you can easily adapt to a specific project. Each major algorithm is presented in the style of a design pattern that includes information to help you understand why and when the algorithm is appropriate.

With this book, you will:

• Solve a particular coding problem or improve on the performance of an existing solution
• Quickly locate algorithms that relate to the problems you want to solve, and determine why a particular algorithm is the right one to use
• Get algorithmic solutions in C, C++, Java, and Ruby with implementation tips
• Learn the expected performance of an algorithm, and the conditions it needs to perform at its best
• Discover the impact that similar design decisions have on different algorithms
• Learn advanced data structures to improve the efficiency of algorithms

Book Description

With this digital Early Release edition of HTML5 Architecture, you get the entire book bundle in its earliest form – the author’s raw and unedited content – so you can take advantage of this content long before the book’s official release. You’ll also receive updates when significant changes are made, as well as the final ebook version.

With HTML5 applications, developers are faced with new challenges, such as handling offline capable clients, merging data from the client back to their server side storage, and throttling resources based on the device connection speed. The UI is no longer generated by the server and pushed to the client. Today, developers are forced to look at web application architecture from a different perspective where the browser and JavaScript are taking just as much spotlight as server side code (such as Java or Ruby). This book shows them how.

Table of Contents
Chapter 2. I The Mobile Web
Chapter 3. Mobile Performance Techniques
Chapter 4. HTML5 From the Server Side
Chapter 5. WebSockets

Book Description

As Ruby pro David Copeland explains, writing a command-line application that is self-documenting, robust, adaptable and forever useful is easier than you might think. Ruby is particularly suited to this task, since it combines high-level abstractions with “close to the metal” system interaction wrapped up in a concise, readable syntax. Moreover, Ruby has the support of a rich ecosystem of open-source tools and libraries.

Ten insightful chapters each explain and demonstrate a command-line best practice. You’ll see how to use these tools to elevate the lowliest automation script to a maintainable, polished application.

You’ll learn how to use free, open source parsers to create user-friendly command-line interfaces as well as command suites. You’ll see how to use defaults to keep options simple for everyday users, while giving advanced users options for more complex tasks.

There’s no reason a command-line application should lack documentation, whether it’s part of a help command or a man page; you’ll find out when and how to use both. Your journey from command-line novice to pro ends with a look at valuable approaches to testing your apps, and includes some fun techniques for outside-the-box, colorful interfaces that will delight your users.

With Ruby, the command line is not dead. Long live the command line.
