You can add Rust support in different ways, but I prefer using Yocto’s built-in cargo class. With this method, […]

It wasn’t soldered onto a PCB or hidden under a heatsink. Instead, it sat fully exposed on a breadboard, with the address bus, data bus, control lines, and all the […]

Or maybe they just remind you of someone else?That’s exactly the kind of familiar feeling I had, not with a person, but with a piece of technology. The first time I started reading about Zephyr, […]

We left the “stupid black boxes” era behind, looked at why embedded devices must have network-level protection, and then unpacked how and why Linux firewalls work with nftables, and why it’s a much cleaner, modern approach compared to the old iptables/xtables world.We also mapped […]
