When your Ruby On Rails Website gets famous you're going to wish you implemented proper caching. Are you worried? Maybe just a little?This tutorial is going to show everything you need to know to use Caching in your Rails applications, so when you get digg'd or slashdot'd you won't be left begging your hosting provider for more CPU processing power.

The impending release of Ruby on Rails version 3 both refines and expands the capabilities of the popular Web application framework. Offering cleaner controllers and savvier SQL queries, you can expect to write less code than before. Better yet, you can include most of the components of Rails 3 in any Ruby application. Here's a look at what's changed for the better.

IronRuby is Microsoft's implementation of Ruby on the .NET framework. This article introduces IronRuby, and covers running Rails applications in IronRuby as well as potential issues to look out for

This article details the components of Rails and shows you how it works.

Ruby on Rails is increasingly showing up as the base framework for sophisticated and scalable applications of medium and large size. Because Ruby is an interpreted language, to bend Rails to your will, you will need to employ many different caching strategies. This article explores the caching strategies that are available to you.

Real life experience on programming with Ruby on Rails by Ron Jeffries

With configuration, installation, and the use of Hadoop in single- and multi-node architectures under your belt, you can now turn to the task of developing applications within the Hadoop infrastructure. This article explores the Hadoop APIs and data flow and demonstrates their use with a simple mapper and reducer application.

Suppose you are a C++ developer and you need to do some prototyping quickly in Ruby. When you pick up a Ruby reference book like the Pickaxe or browse the Ruby site, you see familiar constructs like class declaration, support for threads, and exception handling. Just when you thought you knew how Ruby works, you realize that concurrency in your Ruby code is not behaving like Boost threads, catch and throw are not what they seem, and others have used something called self all over the place in their Ruby script.

This book is a tutorial and reference for the Ruby programming language. Use Ruby, and you'll write better code, be more productive, and enjoy programming more. These are bold claims, but we think that after reading this book you'll agree with them. And we have the experience to back up this belief.

Using the Ruby on Rails framework it is relatively easy to develop complex systems that are backed by an Oracle database, but this ease doesn't exempt the developer from the need to optimize the data model and the code that manipulates it. This article is for developers working with Ruby on Rails applications on an Oracle database, with special attention to those having a live application that needs to be optimized. You will learn which options tweak the parameters that handle the connection to the database for the Oracle adapter to boost the application performance, as well as get a useful plugin to track down the query execution plans for live applications. You'll build a simple set of models and look at various typical queries on them, exploring how you can improve their efficiency.
