[FRIAM] Automata with FFT

[glen]

Very cool! Thanks.

In particular, our property abuts "the ravine", which is a semi-wild place. The permaculture categories might help me orient my own intuition (that everything in the ravine should be left alone) with my neighbor's (clearing the whole area and reintroducing natives). He owns the majority of it. So, c'est la vie ... or perhaps "telle est la mort". (Don't blame me. I don't know French.) One thing this zone 0-5 model might permit is modularity. That blog post implies such with the inverted garden interface. But it seems like there could be pockets of zone0es in wild areas and pockets of zone5s in urban areas, particularly in sprawling cities like LA or Houston. Growing up in Houston, where every square inch of semi-abandoned land seemed rapidly reclaimed by the swamp, is probably the source of my skepticism with my friends' diversity doctrine.

There's a lot to digest in the biophilia links. I have to confess, I haven't given pattern languages much attention. It always seems motivated by geometry, which fails for me. Of course, I'm familiar enough with software patterns. But that's always failed for me as well. They seem too ephemeral, unstable ... i.e. not real, convenient fiction, and *perfect* opportunity for gurus to blind others with their gobbledygook mouth sounds. I guess it reminds me of category theory, too abstract for my ape brain. But maybe some of his earlier work on Clifford algebras might motivate me? I could start here, I guess: https://link.springer.com/chapter/10.1007/978-1-4757-1472-2_41

Thanks again.

For example, I have a couple of biologist friends, one meso (bugs) and one macro (ungulates), who thought I was being contrarian when I challenged their assertion that biodiversity in urban areas was *obviously* lower than that of natural areas like forests. Of course, I admit my ignorance up front. Maybe they are. But it's just not obvious to me.

I think the permaculture community represent a fertile laboratory for doing *some* experiments as implied by Glen's questions.

Permaculture is a domain of recognizing and exploiting "happy accidents".

>> Since then, they've presented (meso and macro) arguments that justify their position. It does seem obvious that urban areas trend to more adaptable animals like coyotes and raccoons and less so to, say, deer. The bugs are more interesting. Meso guy found some articles that show "species" diversity in urban areas is roughly the same as natural areas. But phylogenetic diversity is clearly lower in urban areas. That seems counter intuitive to me. It's a cool result.

Because Bert has come at it more from the ALife/engineering approach, and Will’s interests run more in the direction of proving capabilities of broad classes of systems, often interested in their aggregation as categories  (and also about the role of simulation as a replacement for proof in systems that produce complicated enough state spaces), it should be a productive and interesting collaboration.  I don’t know how engaged others are in the Google group on this specific project, because I am too far outside that loop.
