OS3-RNode, an RNode-Compatible LoRa Modem on CH32V003
I built OS3-RNode as a tiny RNode-compatible LoRa modem firmware for CH32V003 + E22-900M22S. It is based on a small deterministic event-driven core, with no scheduler, no threads, and bounded interrupt work. The goal was to make a minimal and auditable transport for Reticulum/NomadNet on very constrained hardware. The article has the architecture notes and a firmware link. Feedback on the event model, failure handling, and interoperability tradeoffs would be useful.

I thought it'd be interesting to use Linux PSI (Pressure Stall Information) for an LLM runtime to trim the KV cache. This is mainly useful imo for edge devices like the Jetson Orin super nano kit which have unified memory. I haven't benched much, but plan to do so more over time and see if I can make a real use of it as I run local LLMs. Let me know if it makes sense :P (I of course vibed this idea)
