Pixel Art Notes

Pared down notes for my own use, derived from http://www.pixeljoint.com/forum/forum_posts.asp?TID=11299

Palette

Start with as few colours as possible; expand both shades and hues only as is necessary:

1. register particle account

2. setup board

unpackage the board and plug it into your laptop

particle's "getting started" guide:

hackergrrl

var hyperlog = require('./')
var level = require('level')
var through = require('through2')
var memdb = require('memdb')
var TopoSort = require('topo-sort');
var dedupe = require('dedupe')

if (process.argv.length !== 4) {
  console.error('USAGE: rebuild <LEVEL-DIR> <NEW-LEVEL-DIR>')
  process.exit(1)

understanding callbacks & async code flow

Consider setTimeout: a very simple asynchronous function. It takes two parameters: a callback and a delay:

setTimeout(fn, delay)

In use, it might look something like this:

hackergrrl

function getOsmDocFromVersionId (osmdb, version, done) {
  osmdb.get(version, function (err, node) {
    if (err) done(err)
    else done(null, getOsmDocFromHyperlogNode(node))
  })
}

function getOsmDocFromHyperlogNode (node) {
  if (node.value && node.v) return node.value.v  // Returns the OSM document (has 'type', 'lat', 'lon', etc)
  if (node.value && node.d) return null  // This document is a deletion marker for an older document
