This is perfect, for completeness, you can extend it with CORS + no-store and ms epoch.

This is also why I lean on a tiny JSON route with simple CORS. For anyone wiring this up, they can add Access-Control-Allow-Origin: * (or site origin), and Cache-Control: no-store Also, watch for mixed content (HTTPS page trying to fetch HT

Yes, many servers don’t expose Date to browsers (Access-Control-Expose-Headers), so you can’t read it cross-origin. Also, CDNs/proxies can cache or rewrite headers, my goal was a boring, local /time on the same gateway the tech is

I wanted to see how far WebGPU could go without build steps or frameworks. I simulated 10k robots with collision avoidance entirely on the GPU via HTML hitting ~120 FPS on an M1 Mac.

Note: This is a sanity probe, not a time discipline tool. rtt/2 and browser timers can be noisy, so treat green/red as a hint, not truth, especially on congested factory networks.

The real skill is knowing when not to make something dependent otherwise you just slow yourself down.

The feedback is loud and clear and honestly it's fair, though I feel sad. My intent was to use Apple as a metaphor for interoperability, but it came across as a fantasy post totally disconnected from the real world hell of industrial a

I chose "Debugging Humidity" as a metaphor for all the invisible, pervasive environmental factors that you have to deal with in the physical world. Latency, power flicker, interference, etc. It's the "stuff in the air&qu

There is absolutely no substitute for an engineer seeing, smelling, and hearing the environment where their code will actually run. The number of times a mysterious software glitch on a remote device has been traced back to insect nests, ro

Wow, that's a fantastic and terrifying example. "Retrieving the device starts at $10K" is about as high-stakes as it gets for software reliability. It perfectly crystallizes the difference between rebooting a cloud instance f

Your suggestion of actuator.rotateTo(Degrees(90)) is precisely the right way to engineer a robust, idempotent command for the physical world. I used the simpler, non-idempotent rotate(90) example intentionally to illustrate the default trap

Haha! That's brilliant. You have summarized my entire blog in four words :P

This is a great visual guide! I’ve also been working on a similar concept focused on deep understanding - a visual + audio + quiz-driven lesson on LLM embeddings, hosted on app.vidyaarthi.ai. https://app.vidyaarthi.ai/ai-tut

Thanks for the feedback, that's a really good feedback, we will add more interactive controls in next try of this for learners to control the flow rather than us controlling it.
