cartodb js > cartocss bug? This file will display the cartodb layer without labels. Uncomment lines 71-72 and comment out line 73 to see that the layer no longer draws. This cartocss is the same that I used in the CartoDB Dashboard.

OpenStreetMap cheat sheet for Common terms and lexicon used in OSM. [assuming node, line, and polygon is covered in the presentation itself)

Changeset: A group of changes that you made to OSM data. Once uploaded to OSM, your edits are instantly available to others if they download OSM data. They may take a few minutes or several hours to appear on the map.

Extract: A large chunk of OSM data for a specific area (like a state, country, or geographic area).

Layer: A data source that's displayed on a slippy map (often is thought of as a group of tiles stitched together). (It also has another meaning in OSM, but don't worry about it right now).

Render: to convert from the OSM data into an image. Rendered data is a map.

Stylesheet: it means a text file of rules that define what features (like roads, buildings) are displayed, and how (what color should the road be ? How wide should be? What icon should be used for a restaurant?) on a map.

Geosupport w/ JS and node-ffi

Geocoding 10,000 addresses a second with NYC's Geosupport library and Node FFI

Following on Chris Whong's excellent writeup of how to make calls directly to NYC's Geosupport client and this first attempt at generalizing it, here's a way that let me geocode about 10,000 addresses a second on Ubuntu using Node FFI.

Note: this assumes Ubuntu - other Linux is probably fine but may need adjustments.

First, install the basics:

# Update, install Node and unzip (if needed)
