Setup nix, nix-darwin and home-manager from scratch on an M1 Macbook Pro
###
### [2023-06-19] UPDATE: Just tried to use my instructions again on a fresh install and it failed in a number of places.
###. Not sure if I'll update this gist (though I realise it seems to still have some traffic), but here's a list of
###. things to watch out for:
### - Check out the `nix-darwin` instructions, as they have changed.
### - There's a home manager gotcha https://github.com/nix-community/home-manager/issues/4026
###
# I found some good resources but they seem to do a bit too much (maybe from a time when there were more bugs).
# So here's a minimal Gist which worked for me as an install on a new M1 Pro.

Comonadic explorations
- Is day convolution as comonadic composition really free? What's the difference with Kenneth's Distribute based composition?
- How do specific comonads compose?
- cursors -> apart
- The cursor like intuition, extended to a range, starts feeing exactly like a lens !?
- If the data space has this comonadic structure, how does it compose with the ui components?
- If we can model time also as a comonadic cofree module/pattern, how do we sync with an event loop? Seems like the shape of the time dimension(s?) define a clock type!!! Actions are a time dimension :O ?!? I think that's also the coeffect/effect dimension (tricky with cursors on data, does it depends on whether a query is sent or should we abstract that out?).
- Chris's Zippers feel like Pairing
