My main activity at the momment is developing a way of converting Moodle courses into static web pages that can be used to provide a long term record of the state of a course at a fixed point in time, and can be made available to students for revision purpose.
CCReader is a derivative of my earlier QTIViewer application that will allow teachers to preview IMS Common Cartridges on desktop computers.
A minor sideline, which I hope will evolve into a useful and widely used utility is my web service code and WSDL generator, d2wsdl. It allows code written in a simple pseudocode language to be used to generate nice, WS-I compliant WSDL, and hopefully will also eventually generate the necessary PHP, C# and Java code to make web services that really interoperate with no code massaging required.
I am also working on a PHP code generator that converts simple class definition like data designs into near complete Data Access Layer code for SQLite or MySQL. It can also be used to generate the database definition XML used by Moodle.
