Episode notes
Boot-Time Work Nobody Sees
- Cliff Biffle describes owning the low-level firmware work that happens before the main CPU powers on.
- He prototyped PCBs himself and designed the first board before hiring electrical engineers.
Docs After Prototypes
- Oxide uses living documentation and RFDs to capture decisions and onboard new people.
- Prototypes are encouraged first, then docs are written to build consensus and transfer knowledge.
Rust For Embedded Stack
- Oxide writes most low- and mid-level code in Rust while using a tested Illumos descendant for host-level C code.
- Rust enables safer, maintainable firmware and extensibility at the OS boundary.
