OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

dgoodwin fork for Python3 and Los Angeles downtown.

The frequency.py script:

Fetches all trips on a given date, between a start time and end time, inside of a bounding box
Calculates the number of connections between every stop
Uses a colormap and line width to show more frequent service

Ruby script to convert stops.txt and shapes.txt to GeoJSON.

	sudo apt-get install build-essential libpcre3-dev libssl-dev libgeoip-dev

	# Install standard Nginx first so that you get the relevant service scripts installed too
	sudo apt-get install nginx

	# If you want to access Postgres via Nginx
