Ken VanDine found his way into open source by following his innate curiosity about how things worked. Unable to inspect and modify the code of proprietary operating systems, Ken discovered Linux and open source via Slackware in 1993. Soon, he was responsible for High-Performance Computing (HPC) at a large pharmaceutical company, architecting a globally distributed Linux cluster and building purpose-built Linux systems, which led to future roles in open source, solving software distribution and optimization. Ken has over 30 years of experience building Linux distributions, with over 16 years working at Canonical on Ubuntu. During his career at Canonical, his focus has been on GNOME, Ubuntu Desktop, and Snap integration. When Ken is not working, he enjoys volunteering with Kramden Institute, a local non-profit that aims to bridge the digital divide, coaching youth baseball, and spending time with his family.
