Command Line Heroes

Red Hat's series, hosted by Saron Yitbarek, tells the history of software, hardware and open source through the people who built them. Each season has a theme and episodes stand alone, so it is easy to pick a subject and go. Season four, about the people and teams who changed the rules of hardware, is the best way in for listeners more interested in machines than code. The show finished after nine seasons in 2022, and its brisk, well-produced episodes rarely waste a minute.
