Google has created the Coder project, for developing Raspberry pi web applications.
As you may know, Raspberry PI is an ARM computer, having the size of a credit card. It uses a special Linux distribution, optimized for the ARM architecture. Because of its low resource consuption, it is ideal for hosting small web services.
To install Google Coder, just download the Coder app from here and put in on the SD stick. After you have successfully installed Coder, go to http://coder.local, from the Chrome web browser, in order to access the web server.
The aim of this application is to provide an interesting learning environment to both technology geeks and students, in order to help them learn web developing basics.
