Ruby On Rails
The document discusses Ruby on Rails, an open-source web application framework. It is optimized for programmer happiness and productivity by favoring convention over configuration, allowing developers to write code more quickly. Ruby on Rails uses a model-view-controller (MVC) architecture and is widely adopted by companies like Twitter.
