https://leanpub.com/readevalprintlove004/read I don't recall if this was shared in this channel yet. It is an interesting read on rules engines by Fogus. I particularly like the simplified implementation of a (naive and simplistic) rules system. The "fruit fly" system. Hah. It does shed some light on some ideas at a high level. There is a little mention of Clara in the end "credits" too. So there is that. 😜
