Download and Install Postgres.app

Before we can setup PostGIS we need to have a local version of Postgresql installed and running. The most effecient way to do this is to download and install Postgres.app.

Spatially Enable your Postgres Database

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

This is an adjusted version of EC2 CloudWatch stats for Dashing which is not bound to EC2 metrics but a generic widget for cloudwatch graphs. Visualization is done by Rickshawgraph as in the original example.

First, install the following libraries:

$ brew install unixodbc
$ brew install freetds --with-unixodbc

FreeTDS should already work now, without configuration:

$ tsql -S [IP or hostname] -U [username] -P [password]
locale is "en_US.UTF-8"

locale charset is "UTF-8"

Falsehoods programmers believe about prices

1. You can store a price in a floating point variable.
2. All currencies are subdivided in 1/100th units (like US dollar/cents, euro/eurocents etc.).
3. All currencies are subdivided in decimal units (like dinar/fils)
4. All currencies currently in circulation are subdivided in decimal units. (to exclude shillings, pennies) (counter-example: MGA)
5. All currencies are subdivided. (counter-examples: KRW, COP, JPY... Or subdivisions can be deprecated.)
6. Prices can't have more precision than the smaller sub-unit of the currency. (e.g. gas prices)
7. For any currency you can have a price of 1. (ZWL)
8. Every country has its own currency. (EUR is the best example, but also Franc CFA, etc.)

How do I round to 2 decimals?

In python, you have floats and decimals that can be rounded. If you care about the accuracy of rounding, use decimal type. If you use floats, you will have issues with accuracy.

All the examples use demical types, except for the original value, which is automatically casted as a float.

To set the context of what we are working with, let's start with an original value.
