Preparing environment

We need to generate secret key for development environment.

mix phoenix.gen.secret
# ednkXywWll1d2svDEpbA39R5kfkc9l96j0+u7A8MgKM+pbwbeDsuYB8MP2WUW1hf

Let's generate User model and controller.

Just in case you need it for reference in the future, this is the problem we normally see people run into: People will sometimes have called the environment variable during a module attribute assignment. Like the following:

defmodule MyAPP.APIClient do
  @api_key System.get_env("API_KEY")
end

Note:

2008.csv file is too large so it is not in my git repository. If you want to run the scripts then you may have to download the file from http://stat-computing.org/dataexpo/2009/the-data.html.

Parsing the data

Final Project - Data Visualization Course

Udacity Data Analyst Nanodegree

For this final project I will use 2008 flights data that I downloaded from http://stat-computing.org/dataexpo/2009/the-data.html. The file doesn't have the geographic coordination of each airport so I downloaded the file that contains the information of coordinates of each airport from https://gist.githubusercontent.com/tdreyno/4278655/raw/7b0762c09b519f40397e4c3e100b097d861f5588/airports.json.

Usage

(Create a symlink pytest for py.test)

pytest [options] [file_or_dir] [file_or_dir] ...

Help:

create tasks T{NNNN} asign them
create a branch with name like "T{NNNN}-boo-hoo"
git checkout -b T1234-boo-foo
commit changes on that branch until it gets ready to be reviewed
git commit -am 'first'
git commit -am 'now it works'
check if it's lint free (NOTE: it runs lint against only modified files)
arc lint
push a review request to the server. This will create a diff with id D{NNNN}
arc diff

	# Backup
	docker exec CONTAINER /usr/bin/mysqldump -u root --password=root DATABASE > backup.sql

	# Restore
	cat backup.sql \| docker exec -i CONTAINER /usr/bin/mysql -u root --password=root DATABASE

	# Ask for the user password
	# Script only works if sudo caches the password for a few minutes
	sudo true

	# Install kernel extra's to enable docker aufs support
