Rusty is a well-known Linux kernel maintainer, renowned for his foundational work on modules and iptables. After 14 years as a senior developer at IBM, he took a six-month sabbatical to work on cryptocurrencies. It was his top-notch work and writings during this period that brought him to our attention. Rusty has worked on a plethora of low-level code over the years, spoken at dozens of conferences around the world and also founded the first Australian Linux conference. He continues to maintain some Linux kernel parts as a hobby, while devoting most of his time to exploring the emerging frontier of Bitcoin development.
