Railscast #204 - XSS Protection in Rails 3
It is easy to be vulnerable to cross site scripting attacks in earlier versions of Rails, but Rails 3 solves this by automatically escaping unsafe input.
Use The Cucumber
The Cucumber behavior-driven development framework is appreciated by developers from many languages. It makes it easy to write plain-text stories that run executable Ruby code against your application.
In this hour and ten minute screencast, you’ll learn the basics of Cucumber. You’ll learn the syntax, organization, and philosophy of writing Features, Scenarios, and Steps. You’ll build an application and learn where unit tests are a better fit.
The PeepCode series on RSpec kicked off ou... View More

Since then more Rails applications have gone into production, additional techniques have been developed for optimizing performance, and more open source libraries have been published. In this talk he will first give a quick introduction for those just getting their feet wet with optimizing Rails applications. However, the majority of the talk... View More
