Debugging Humidity: Lessons from deploying software in the physical world physical-ai.ghost.io

camtarn2 hours ago

Some of my code gets deployed to a PLC aboard a wave power generator hundreds of metres offshore, with a cellular link that might go down in a storm. If something gets unrecoverably wedged, retrieving the device starts at $10K to hire a ship.

I feel this blog post hard.

> This is why so many “IoT platforms” die in pilot purgatory. They are built by cloud engineers who underestimate the friction of the real world and overestimate the availability of bandwidth.

Indeed. That's why it's important to send your engineers along with the sales folks to these sites. If anything just to get a perspective on things like that.

And bugs, real ones not just nice abstract software ones. So you may find yourself debugging spider webs and ants crawling around, which always makes for great puns and stories.

Okay, but what about humidity? I was excited to read about a failure mode where the moisture content of air mattered, or at least get mildly clickbaited into learning about a tool called Humidity. Instead there are no other references to humidity apart from the title

The cloud is 100% humidity, I suppose.
