The Linux Operating System is 20 years old. This podcast series, presented by the Senior Lecturer in Computing at The Open University, Blaine Price, tells the story of an extraordinary operating system that in two short decades has grown from a students’ project to the foundation of the internet. Linux runs on everything from your wireless router and Android Smartphone to CERN's most powerful computer. It has championed a whole new philosophy of collaboration and freedom in the software development community. We will hear from its users, its innovators and its originators.
