DJ Adams is an old SAP hacker who still thinks that JCL and S/370 assembler are pretty cool. In recent years, he's been successfully combining open source software with R/3 to produce hybrid systems that show off the power of free software.
He's the author of O'Reilly's Programming Jabber book, contributes articles to O'ReillyNet's P2P site, and has to own up to being
responsible for the Jabber::Connection, Jabber::RPC, and
Jabber::Component::Proxy modules on CPAN.
