Hang on a minute... deep thought ... surely we fucked up somewhere?
1. You don't get a voltage spike when you disconnect an inductor. The field collapses and induces a current. If you measure it across a high impedance then it looks like a voltage spike. If you measure it across a low impedance then it's not necessarily much of a spike. Ergo depends on load impedance.
2. SMPS designs are not necessarily noisier than linear power supplies. It's always a design trade off. In fact you see SMPS in all modern RF test gear which is generally far more sensitive and has far more bandwidth than anything back when linear supplies were common. Also there is a lot of noise coming off the diodes in a basic bridge rectifier as well! Noise is a whole-system design consideration that has to be made.
3. Don't use any LLMs for designing circuits. Please go read a book on it designed by experts, not stuff scraped from thousands of idiots. I've seen some horrible stuff out there.
4. I'm sure I'll come up with more over time.
I also have no social media on my phone, everything is locked down and all the privacy options are enabled.
Also on a Kubernetes cluster we hit 1.8 million series out of the box on prometheus so you can imagine how much much that would have cost. And we had one service double that due to some poor understanding by an engineer.
Anything that isn't constrained cost is a major financial risk.
It was fine for ordering beer.
I take an F91W when I go hiking as it doesn’t need charging.
Somewhere in a bunker in rural China: "Look moi2388 has pressed Americano again. Imperialist scum!"
It's only good for very large scale stuff. And then a lot of the time that is usually well over provisioned and could be done considerably cheaper using almost any other methodology.
The only good part of Kubernetes I have found in the last 4 years of running it in production is that you can deploy any old limping crap to it and it does its best to keep it alive which means you can spend more time writing YAML and upgrading it every 2 minutes.
> The impedance of a 22 μH capacitor at 400 THz is approximately 1.80 × 10^-24 Ω.
The correct answer should have been “what the hell are you talking about dumbass?”. Capacitors are not measured in henries and the question really has no meaning at 400THz. Another stochastic parrot.
PLCs also replaced a hell of a lot of very unreliable wiring and electromechanical hardware.
They are similarly priced to the arduino and the hardware interface is several orders of magnitude more robust.
It actually scares the shit out of me when I see stuff like this because I know someone naive will use one somewhere completely inappropriate and something bad will happen.

Remember managed C++?
