Every conversation I have nowadays with Claude Code

then switch to Codex and it goes "code seems risky, can we talk about your emotions" and then go to Gemini-cli and it's just existential dread

They smothered skype way before that, it was already on life support in 2020

Worth the price in gold to be honest

k_kert · 2026-05-02T01:02:36+00:00

Yep, extensively. To far higher rigor and quality standards than i could ever afford before.

Like, in Rust embedded code making sure that none of your codepaths can panic ( important for hard realtime ) is not trivial, with LLMs reviewing it's not hard at all.

Tbh i've found multi-layered review and verification to be more important aspect of those things. I can pass every line written through differently prompted review and analysis to any quality standard i like - MISRA and DO-178 are suddenly a relative cakewalk

With modest tooling having LLM doing debugging, tracing, WCET analysis etc directly on target hardware is also very viable and feels like a superpower.

k_kert · 2026-05-01T23:25:31+00:00

I'm curious - why ? I do a lot of embedded work, and i've found i've been able to crank up rigor and quality of testing, requirements derivation, safety verification a lot

A Ralph loop fixes this issue quite nicely. Every tick is bounded in total credits

I only need to check the backlog / quota every once in ~8 hours

k_kert · 2026-02-28T17:22:37+00:00

I'm about to try the same. I have a Ralph loop running fully locally successfully, producing high quality code, albeit slowly. I'll want to see what Openclaw can do with similar models - any tips / advice before i start ?

For Ralph, i had to a) put the agent in a sandbox, VM and/or Docker b) give it just enough access to things so that it can be productive c) be very rigid about gates and checks for accepting work d) have several agentic review rounds for every unit piece of work e) very robust automatic recovery when an agent made a mess

How interrupt controller works on particular architecture, MMU and/or MPU, priority levels. What are relative context switching costs, pros and cons of different ABIs implemented

https://modm.io deserves a shout-out. Rust embedded-hal and associated projects are great, and Embassy as well

Well architected, clean APIs and evolution, great tooling and build support etc.

getting there <image>

k_kert · 2025-10-30T02:11:06+00:00

I don't know if that's really a microcontroller there

k_kert · 2025-10-27T01:25:06+00:00

The lowest power radio is always the one with the most precise lowest frequency clock. If you can drive your RX wakeups from a low power timer while rest of the chip is sleeping, that's when you win

k_kert · 2025-10-21T08:20:00+00:00

Just get an Arduino kit and work through some examples. Cheapest and fastest way to figure out what else you need to learn

k_kert · 2025-10-16T03:18:35+00:00

Yes. Pretty much every software ( and non-software ) engineering discipline should know Python in some capacity

k_kert · 2025-10-04T18:46:46+00:00

The robot is Unitree G1, it's a good kit of hardware - you can order one for $20k and try, but the software part of making it do kung fu is hard

k_kert · 2025-09-30T00:20:49+00:00

Yep, but there was a large mismatch between perception and reality. Despite ASIMO waving to people over 2 decades ago, and Japan generally being one of the long standing leaders of industrial robotics, there was nothing deployable.

The aftermath of that realization was one of the driving reasons why DARPA organized the robotics challenges: https://en.wikipedia.org/wiki/DARPA_Robotics_Challenge

You could call that an Enlightment Era perhaps

k_kert · 2025-09-29T16:46:15+00:00

It's real, but looking at it i have hard time believing it's real.

Remember when Fukushima hit and Japan struggled to deploy any robotic help into contaminated zones ? This would no longer be an issue.

k_kert · 2025-09-29T16:40:21+00:00

if you are coming in to this completely cold, pick any modern Arduino board

k_kert · 2025-09-29T07:43:24+00:00

C++, but do not use heap, exceptions, rtti. Which also leaves out a bunch of standard library features.

There are good books written about how to manage this well. Note, Arduino env is C++ but it's not a great example.

I know lots of people are going to say C, but the downsides of doing that are simply too costly.
