Josh Clulow, Patrick Mooney, and Steve Klabnik join the hosts to discuss Helios, the OS that runs on the Oxide Rack. They touch on topics such as illumos, distros, Rust Tier 2 support, and Bryan's sleeper bug from 1991. They also explore the challenges of software distribution, developing software for Windows with Rust, memory usage, upstreaming code, and exploring computer architecture. The chapter descriptions include discussions on books, the Unix wars, the Helios sled, and database options.
