Writing

The idea

Making Embedded Systems is the closest thing the field has to a shared first book: it comes up in more than one in four threads that recommend any book. Around it, the reading list leans on electronics, C, and books written for one specific chip.

The idea

Zephyr 4.5 adds a new architecture, a video and multimedia stack and a native LoRaWAN backend, but its bigger job is being the last release before LTS4. Test against it now, while breakage is still cheap to find.

The idea

On embedded, the bugs that cost the most time are often not in your code but in the physical world, so debugging them is mostly search. The engineers who are fast at it aren't better coders; they've built the visibility that makes the search short.

The idea

Cloudflare Pages already adds a noindex header to every preview deployment, so you don't need application code to keep previews out of search. The wider lesson: don't solve an infrastructure problem inside your app.
