Revisiting the NetBSD Build System (blogsystem5.substack.com)
I recently picked up an embedded project in which I needed to build a highly customized full system image with minimal boot times. As I explored my options, I came to the conclusion that NetBSD, the often-forgotten BSD variant, was the best viable choice for my project.

Demystifying Common Microcontroller Debug Protocols [video] (media.ccc.de)
Many developers know that the answer to "How do I debug this microcontroller" is either "JTAG" or "SWD". But what does that mean, exactly? How do you get from "Wiggling wires" to "Programming a chip" and "Halting on breakpoints"? This talk will cover how common debug protocols work starting from signals on physical wires, cover common mechanisms for managing embedded processors, and ending up at talking to various common microcontrollers.

Subnet routers: how do they work? (tailscale.com)
The most straightforward way to use Tailscale is to install the client on every node that you want to add to your network. But there are some cases, like embedded devices or existing VPCs, where a direct installation on each node isn’t feasible. That’s when you can turn to a subnet router.

OpenWrt One router officially launched (openwrt.org)
The OpenWrt Project is a Linux operating system targeting embedded devices. Instead of trying to create a single, static firmware, OpenWrt provides a fully writable filesystem with package management. This frees you from the application selection and configuration provided by the vendor and allows you to customize the device through the use of packages to suit any application.

Making Sense of Real-Time Operating Systems in 2024 (hackaday.com)
The best part about real-time OS (RTOS) availability in 2024 is that we developers are positively spoiled for choice, but as a corollary this also makes it a complete pain to determine what the optimal choice for a project is.
