2025 Review

Jared Wolff of Circuit Dojo joins us to discuss low-power cellular IoT with the Nordic nRF9151 Feather: microamp sleep currents, reliable LTE-M connectivity, satellite NTN, Zephyr RTOS, and Lion, his self-hosted Rust IoT server built on CoAP, DTLS, and CBOR.

How we record and publish this podcast with a self-hosted static site and a virtual studio: Zola and the simplepod theme for RSS, VDO.Ninja for low-latency WebRTC calls, OBS and Audacity for recording, and a Claude Code skill that transcribes with Whisper and publishes in minutes.

Technical writing for developers with Michael Lynch, author of Refactoring English. We cover structuring a book for reader ROI, cutting aggressively, using AI as a teacher instead of a ghostwriter, and a self-publishing toolchain built on Asciidoctor, Nix, and Hugo.

Tim Bird of Sony joins us on Space Grade Linux (SGL) — the ELISA-incubated project bringing embedded Linux to spacecraft. We cover the meta-sgl Yocto layer, fault-tolerant file systems, QEMU radiation simulation, fleet OTA updates, and how Linux already dominates on-orbit compute via Starlink.
