I have been hearing this term (REST) alot lately and during my quest to find telecommuting work on internet I saw this term many many times. So today when I had a little free time I decided to do little research to find out what the hell it is. Once again, to no surprise, its a complicated term for a simple simple concept. Its not a framework or a standard or a protocol. Its simply a way of building web applications or web services. You can build RESTfull apps using any framework Rails or DJango or whatever you like.
Here you can find a simple tutorial about REST or you can follow this link to see how to build RESTful applications in Rails
