My first encounter with GIS was about 35 years ago when I developed a program on VAX. The first FOSS4G conference I attended was held in Victoria, Canada. I was working on the Japanese localization of QGIS. In recent years, I've been mostly involved with organizations that support those who need IT during disasters, and I sometimes use spatial information in those activities.
