I've written the award-winning books Code Reading and Code Quality: the Open Source Perspective, I've put together the UMLGraph declarative UML diagram tool and Java UML doclet, I've managed the IT systems at the Greek Ministry of Finance, I've worked for Google, and I've implemented the version of sed that's distributed with BSD Unix and Mac OS X. In a previous life I was a four times winner of the International Obfuscated C Code Contest.
