I'm behind most of the stuff behind 40Hz.org. Currently, this site serves as a repository for my current and past open source projects and to promote techniques for platform independent information exchange such as XML.

Projects
XML
Main focus on Active Hypertext Documents, implementations include JKino and Kino runtime environments.
Newton MessagePad
Since currently, no equally capable, versatile and integrated tool exists to replace the Newton platform, a number of Newton open source software projects has been published on 40Hz.org. Among these are time management and XML-related packages.
Other
Other areas of interest include the programming languages Eiffel and Lua and the integration tool SWIG.
