I’m still looking for a breakthrough, but have learned things about building and executing finite automata that I think are worth sharing.
This piece has to do with epsilons; anyone who has studied finite automata will know about them already, but I’ll offer background for those people to skip.
I’ve written about this before in Epsilon Love.

I haven’t shipped any new features for Quamina in many months, partly due to a flow of real-life distractions, but also I’m up against tough performance problems in implementing Regular Expressions at massive scale. I’m still looking for a
