I want to share an interesting project that has appeared on the Web recently : the AirXCell project.
(As some of you already know, I am somewhat involved in this project :-)

AirXCell is an online R application framework currently supporting a programmable spreadsheet and an R development environment.

AirXCell is based on R - The GNU R Project for Statistical Computing. Current version is still somewhat limited yet fully functional.

Quoting the AirXCell User documentation :

AirXCell intents to revolution the world of spreadsheet applications and computational software by providing a product that:

  • implements a web application on the most cutting edge of technology that outpaces the current classical spreadsheet applications in terms of user experience, potential and features,
  • merges the world of spreadsheet application (e.g. Microsoft Excel, GNUmeric, etc.) and the world of computational software (e.g. Mathematica, Mathlab, etc.) and
  • revolutions the usual approach in spreadsheet applications.

Wow ... This is and will most likely be the most pompous title for a post on this blog usually focused on much more concrete stuff.

Ok let's get into this :

First what is DWR ?

DWR stands for Direct Web Remoting - Easy Ajax for Java.

DWR is a Java library that enables Java on the server and JavaScript in a browser to interact and call each other as simply as possible.

Quoting the official website :

"DWR is a RPC library which makes it easy to call Java functions from JavaScript and to call JavaScript functions from Java (a.k.a Reverse Ajax)."
