The Basics of Capybara and Improving Your Tests
Capybara is a web-based automation framework used for creating functional tests that simulate how users would interact with your application. Today, there are many alternatives for web-based automation tools, such as Selenium, Watir, Capybara, etc. All of these tools have the same purpose, but there are slight differences that make each of them more or less suitable.
The main characteristic that developers are aiming for is the ability to have tests that are modular, easy to write, and easy to maintain. This is especially true in Agile/TDD environments where writing tests is second nature. These tests are expected to give good and fast feedback on code quality. As time goes by, the number of tests grows and it can be a real nightmare to maintain the tests, especially when the tests are not modular and simple enough.
In this tutorial, I will describe some of Capybara key features and explain why it could be your tool of choice for developing web-based automated tests.

Full-Text Search in Rails with ElasticSearch
In this article you will learn how to integrate ElasticSearch into a Rails application.
What is Full Text Search?
A full-text search engine examines all of the words in every stored document as it tries to match search criteria (text specified by a user) wikipedia. For example, if you want to find articles that talk about Rails, you might search using the term "rails". If you don't have a special indexing technique, it means fully scanning all records to find matches, which will be extremely inefficient. One way to solve this is an "inverted index" that maps the words in the content of all records to its location in the database.
