Virtualenv's bin/activate is Doing It Wrong

I'm a Python programmer and frequently work with the excellent [virtualenv][] tool by Ian Bicking.

Virtualenv is a great tool on the whole but there is one glaring problem: the activate script that virtualenv provides as a convenience to enable its functionality requires you to source it with your shell to invoke it. The activate script sets some environment variables in your current environment and defines for you a deactivate shell function which will (attempt to) help you to undo those changes later.

This pattern is abhorrently wrong and un-unix-y. activate should instead do what ssh-agent does, and launch a sub-shell or sub-command with a modified environment.

Once Postgres.app is installed in your computers /Applications directory. Open the Terminal and enter the following two commands

psql -d DATABASE_NAME -f /Applications/Postgres.app/Contents/Versions/9.3/share/postgresql/contrib/postgis-2.1/postgis.sql

Effectively selecting colors for your choropleth map can be intimidating. Thankfully there are a couple of resources that can help us out.

The first is the ColorBrewer website which allows you to tinker with a preset or custom color pallette over a live map.

The second is a preconstructed D3 Map from the mbostock library that contains pre-defined colors, constructed using ColorBrewer.
