The goal of this software is to run a simulation of a model presented by
Moon Duchin in the math session at the Austin regional site for the Metric
Geometry and Gerrymandering Group
In broad strokes, it takes an input shape of some sort and splits it
in four at some point in the polygon (don't talk to me about points out
of the polygon, you degenerate). It assumes that the polygon has some proportion
of one delegate's worth of population, and that the shapes resulting from the split

Chapter 29 - IO

tl;dr: IO doesn't do anything, it's just a way of describing getting a value from somewhere

  • we should be proud
  • some examples of effects:
    • printing st stdout (putStrLn)
  • reading from stdin (getChar)

  • goal: pluggability, so that if someone wants to write the akka-http routes, it's easy for them

  • other question: what's the abstraction? Like -- Meta, or En/Decoder, or...

  • Define Tile Fetching Interface

    • based on layer id
    • something that produces a (Int, Int, Int) => Tile
    • also like Extent => Tile, Extent => Geotiff
    • like TileResolver in existing tile server
  • Cacheing interface -- mostly done, failing tests
