#Nginx Basics for Ubuntu

Please see http://wiki.nginx.org/Main for more information. See http://arstechnica.com/gadgets/2012/11/how-to-set-up-a-safe-and-secure-web-server/ for a tutorial on how to install Nginx.

##Installation To install, you can install the version which is in the standard Ubuntu repositories but it is normally quite old and will not have the latest security patches. The best way is to update the repositories first:

apt-get update
apt-get install python-software-properties

apt-get upgrade

Data Types and Conversion

Convert Series datatype to numeric (will error if column has non-numeric values)
(h/t @makmanalp)

	# Greatest common divisor of 1 or more numbers.
	from functools import reduce


	def gcd(*numbers):
	"""
	Return the greatest common divisor of 1 or more integers

	Examples
	--------

	LOGGING = {
	'version': 1,
	'disable_existing_loggers': False,
	'handlers': {
	'mail_admins': {
	'level': 'ERROR',
	'class': 'django.utils.log.AdminEmailHandler'
	},
	'null': {
	'level':'DEBUG',

	#!/bin/bash
	# virtualenv-auto-activate.sh
	#
	# Installation:
	# Add this line to your .bashrc or .bash-profile:
	#
	# source /path/to/virtualenv-auto-activate.sh
	#
	# Go to your project folder, run "virtualenv .venv", so your project folder
	# has a .venv folder at the top level, next to your version control directory.
