Assume concat is some function sticking two strings together, and uppercase is... well:

Haskell (argument application):

> let a |> f = f a

> "def"
    |> (\x -> concat "abc" x)
 |&gt; uppercase -- (\x -&gt; uppercase x) if you want to be explicit.

This is a rough spec for an implementation of a realtime virtual world using OpenStreetMap data and voxel.js. The basic idea is to encode feature data pulled from Mapbox vector tiles as overzoomed tiles, which can be represented as voxels. This allows for easy scalability, since it utilizes existing algorithms and architecture.

The initial implementation is going on here.

###general

1 voxel = 1 tile at zoom 17 = 1.1943 sq meters
the world is a 33,554,432 x 33,554,432 voxel grid
assume that a server is serving up vector tile pbfs at z15 (mapbox.com, local, etc.)
vector tiles are loaded at zoom 15 and geometry is encoded as 4096x4096 pixel coordinates, which is equivalent to tiles at zoom 24

Taking your nodebot wifi

Controlling your nodebot using a USB cable is great and all, and obviously you could shell out and grab a sparkcore or some other dedicated controller but what if you've got a standard arduino and you want to take an existing nodebot wireless?

Bluetooth is an option and there's this excellent JohnnyFive wiki entry that will help you there. Bluetooth can be a bit flaky though and it's range is pretty lousy. You can also look at things like XBees and what not using point to point serial, but these are expensive and very fiddly to get working.

Really, what we want is a method of transferring data over a nice, simple, standard method, requiring little configuration, low cost and we can utilise a whole stack of the code we've already produced.

Enter the WiFi232 module. These little beauties are [available from AliExpress for $12 each](http://www.aliexpress.com/item/USR-WIFI232-T-wifi-to-uart-tt
