Linus Torvalds on a "debug session from hell" in the Linux Intel Xe GPU driver:
AI did much of the grunt work and "enormously helped" but repeatedly concluded the bug was impossible.
A nice example of AI as a tool, not a replacement for engineering.

A 30-year-old article on finite state machines in Forth that still feels relevant to embedded software today.
The neat idea: turn the state-transition table itself into executable structure, rather than a pile of conditionals.

Is it time to revisit microkernels?
With today's hardware and growing emphasis on safety and isolation, are the classic arguments against microkernels still valid?
Worth a read for anyone working on embedded or safety-critical systems.

The SDK is part of your power budget.
Same ESP32-C6.
Same workload.
Different power consumption.
A nice reminder that firmware architecture matters just as much as hardware when optimising battery-powered designs.

Labelled data is scarce for embedded vision.
SemSim uses semantic similarity to improve semi-supervised image segmentation. An interesting idea with applications beyond medical imaging.

Running DOOM is cool. Building the CPU that runs it is cooler.
This write-up follows the journey from designing a custom RISC-V processor to FPGA implementation and using DOOM to validate the design.
Excellent hardware/software co-design read.

EMiX extends FPGA emulation beyond the limits of a single board by partitioning RISC-V SoCs across multiple interconnected FPGAs. The authors demonstrate a Linux-capable 64-core system spanning 8 FPGAs and plan to open-source the framework.

A remarkable piece of embedded systems history: in 2001, a tiny web server was embedded in a preserved housefly. More than a technical feat, it’s a thought-provoking exploration of technology, media art, and ethics. conceptlab.com/fly/

NASA still maintains some of the Voyager spacecraft code in a 1970s-era programming language that almost nobody on Earth fully understands anymore, and the handful of engineers who do are now in their 80s
