One of the biggest benefits to using ejabberd is the ease with which it is possible to extend the server’s functionality. After only a week of production operation, I’ve already written and deployed four new modules at Chesspark. Let’s get our hands dirty, fire up an editor, and learn how to write a new ejabberd […]

A year or so later, I discovered the potential of XMPP on the Web and created a JavaScript version as […]

My team and I have been working on a new project. When we started Chesspark, we had no visions for a Web version, but that changed quickly after my wife showed me a JavaScript demo she wrote of a chess board with drag and drop pieces.  We took that little demo and added AJAX and […]
