Notejam
The easy way to learn web frameworks
...The easy way to start with a new framework is to compare it with frameworks you already know. The goal of the project is to help developers easily learn new frameworks by examples.
Notejam is a unified sample web application (more than just "Hello World") implemented using different server-side frameworks. Currently python, php, ruby and javascript frameworks are supported.
Currently project is hosted on GitHub http://github.com/komarserjio/notejam
