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.

Why systemd is a problem for embedded Linux (kevinboone.me)
The Internet is full of rants about systemd, and I don’t want this post to be another one. Many of the complaints people make about it don’t stand up to much scrutiny, even the technical ones; and many complaints are not even technical. My particular interest in Linux is primarily for embedded applications; and there, I suggest, systemd is creating a potential (technical) problem.

Async embedded Rust vs. FreeRTOS and C showdown (2022) (tweedegolf.nl)

Why did you write a new RTOS for CHERIoT? (cheriot.org)
I’m often asked why we decided to write a new RTOS for CHERIoT instead of using something that already existed, such as ThreadX, FreeRTOS, or Zephyr. The short answer is that CHERIoT is a hardware-software co-design project and retrofitting ground-up co-design is hard. This post is for people who want the long answer.

Implementing neural networks on the "3 cent" 8-bit microcontroller (wordpress.com)
Bouyed by the surprisingly good performance of neural networks with quantization aware training on the CH32V003, I wondered how far this can be pushed. How much can we compress a neural network while still achieving good test accuracy on the MNIST dataset?

Raspberry Pi 3 fastboot in less than 2 seconds (2020) (furkantokac.com)
This post tells about my journey of fast-booting a Raspberry Pi 3 (RPI). In addition to that, some optimizations are discussed that can be applied to a Qt (QML) application. In the end, we will have a RPI that boots from power-up to Linux shell in 1.75 seconds, power-up to Qt (QML) application in 2.82 seconds.

Embedded Rust in Production? (lohr.dev)
When I mention that we use Rust on the embedded ESP32 platform the most common reaction is a jaw-dropping "This is possible?!". Yes, it is indeed possible! - And we at STABL Energy have used it successfully for over a year now. And because so many people seem interested in why we use Rust and how it is going for us, I decided to write this blog post.

Fixed-point arithmetic as a replacement for soft floats (pigweed.dev)
Fixed-point arithmetic is an alternative to floating-point arithmetic for representing fractional data values (0.5, -1.125, 10.75, etc.). Fixed-point types can be represented as scaled integers. The advantage here is many arithmetic operations (+, -, *, /, etc.) can be implemented as normal integral instructions. This can be useful for embedded systems or other applications where floating-point operations can be too expensive or not available. Clang has support for fixed-point types according to ISO TR 18037.

Ask HN: What do embedded engineers do? (ycombinator.com)
I would very much like to transition to doing more embedded type software that is closer to interfacing directly with hardware, but my only experience in this has been writing code for Arduino, different Raspberry Pi flavors, and sometimes the ESP8266.

Debugging Behind the Iron Curtain (2010) (jakepoz.com)
Sergei is a veteran of the early days of the computing industry as it was developing in the Soviet Union. I had the pleasure of working and learning from him over the past year, and in that time I picked up more important lessons about both life and embedded programming than any amount of school could ever teach.
