Forum OpenACS Q&A: Michael Korns's Deep Green
Before the conference, Linux Journal published an overview of of the presentation that more detailed than the CodeCon one. Robert Kaye gave a report on it from the Feb. 2003 CodeCon presentation. Apparently you can also download an audio recording of the presentation.
Michael Korns also has his own website with much more information than investbyagent.com. All about intelligent agents though, nothing about how their one man mutual or hedge fund handles its trade executions.
