TMPDIR is a podcast about embedded Linux, Yocto/OpenEmbedded, Zephyr, and IoT product engineering. Cliff Brake and Khem Raj dig into BSPs, OTA updates, Linux kernel and device tree work, firmware and RTOS development, build systems (BitBake, Kas), and the editor/CLI tools embedded engineers actually use day to day.

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.
We reflect on 2025, what is new, trends, tools, etc.
Learn about the FPGA and RISC-V products.
Learn from the authors of this useful book.
Learn about Clang, its history in Yocto, and what is new.
Learn what is happening in the meta-tegra layer for NVIDIA embedded products.
Learn how Avocado OS is solving Embedded Linux problems
An overview of rolling releases and how we do it in Yoe
From big-tech to bootstrapping -- how writing has propelled Michael's career
Learn about the interesection of these two cutting edge technologies
What is simplicity, why does it matter, and how do we get there?
In this episode, we discuss why and how to differentiate product and technology.
Discussion of new tools we found in 2024
You can easily end up on your own fork of an OSS project.
Learn how the BeagleBoard Foundation does open hardware
Discussion on what is like to build using Zephyr.
Bob joins us to share his experiences in design, manufacturing, and 3D printing.
In this episode, we go back to the origins of lean in the manufacturing space and learn how it can apply to development.
Learn about the OE4T project for Nvidia SOCs
A discussion about AI at the edge.
Discussion about Mender, OTA update, product vs. platform, etc.
Discussion with Drew about Embedded Linux, technologies, and challenges.
Khem attended EOSS and shares some of his thoughts about the event.
