Ask HN: What are you creating now?

A simulator for hierarchical state machines that lets you empirically test your system behaviour and then take the model and use it to generate the end use code.

I built it specifically for use in designing complex burner management systems sequencing for the LiOH plant we design, but I made it general enough you can use it for any sequenced system, or even business process.

Bonus, built in OPC server so it can bolt on to a HMI for testing/training, or bolt it onto an existing running system inputs in parallel to shadow an existing system with your proposed cut-over system.

For the v-model, when implementing IEC61508 or 61511, it means that now effectively the specification is the product and the v is very shallow.

Apparently I'm writing an interface for Racket's DB functions in Arc because I'm procrastinating on actual productive things like learning Unity and Godot.

Docker images to be used in Jenkins for projects with mixed languages (C++17, PHP7, JDK12) and platforms.

Using wine for running MSVC and jpackage ain't more fun
