Or how about 999 additional computers? They could be really tiny ones, running some kind of operating system designed for putting inside small single purpose machines. You could also add a coloured light on the front of each one and a button that says "copy to NAS".

I'd be interested to find out what sort of anti-islanding techniques they employ. Most inverters are relatively slow to detect grid failure, and if you pull the plug out quickly you might get a shock.

AS/NZ standards prohibit these sorts of systems. Even most models of Victron inverters are not "approved" for grid use without an approved external anti-islanding device, which also vary depending on which energy distributer your are connecting to. Apparently Victron got fed up with dealing with CEC and paying the annual fees to be approved.

I've heard that pressure sensors are the most reliable.

How do you power them? I've used ESPHome previously to scrape my solar analytics for consumption in Home Assistant using $3 Wittycloud ESP8266's. But as yet I haven't found an elegant solution for powering them other than using a USB adapter. It would be nice to find an elegant battery solution for outside sensors.

YubiKeys support cli access with the benefit of being hardware backed, and optionally requiring a physical touch:

  $ ykman oath accounts code <slot>
  Touch your YubiKey...

I wonder if this approach still works with firmware tweaked drives. Anyone remember the "google" spec 320G Seagate drives from circa 2006? The ones with the pink epoxy"? IIRC they benchmarked with flat throughput across the whole platter. Rumours were they were custom spec drive that somehow made it in to the retail channel.

Reminds me of a similar story from a colleague regarding email an email that couldn't be sent with a specific subject. After much troubleshooting by L1/L2 techs it turned out to be a bit pattern error / broken ASIC in a core router/switch.

I've personally twice encountered similar issues, once with FTPS and another with HTTPS, both manifesting as strange cryptographic failures, but ultimately caused by broken network device somewhere in the path.

Reminds me of this PDF I created more than a decade ago from a Postscript implementation of the game of life. Seems it still works, but causes MacOS preview to crash. https://andrewcutler.net/docs/joke/life.pdf
