Giulio Zambon s first love was physics, but he decided to dedicate himself to software development more than 30 years ago: back when computers were still made of transistors and core memories, programs were punched on cards, and Fortran only had arithmetic IFs. Over the years, he learned a dozen computer languages and worked with all sorts of operating systems. His specific interests were in telecom and real-time systems, and he managed several projects to their successful completion. In 2001 Giulio founded his own company offering computer telephony integration (CTI) services, and he used JSP and Tomcat exclusively to develop the web side of the service platform. Back in Australia after many years in Europe, he now dedicates himself to writing software to generate and solve numeric puzzles. His web site, http://zambon.com.au/, is written in JSP on his dedicated server, which, unsurprisingly, runs Tomcat!
