Contributing to Other People's Projects

Contributing to open source software is a difficult and rewarding process. Contrary to popular belief, it does not require a lot of programming skill, but rather patience, creativity, and diligence. In this post I will explain some crucial steps and skills which even experienced contributors sometimes forget. This is not a magic formula, and contributions will require focus and work, but in the end I believe the feeling that you are part of a community and that you have contributed to something greater than yourself is personally fulfilling.

	import matplotlib.pyplot as plt
	t = np.linspace(0,10,1000)
	x = 3.9 * (np.sin(t)**3)
	y = -1 + (3 * np.cos(t)) - (1.2 * np.cos(2t)) - (0.6 np.cos(3t)) - (0.2 np.cos(4 * t))
	plt.plot(x, y, 'r')
	plt.axis('equal')
	plt.fill_between(x,y, color='red')
	plt.show()

	How to use pip and virtualenv
	---------------------------------

	virtualenv is a program for managing python dependencies. If you have virtualenv installed you can manage use different versions of libraries and python with ease.
	Install virtualenv at the system level with one of these:
	```shell
	$ brew install pyenv-virtualenv #osx w/homebrew
	$ sudo pacman -S python2-virtualenv #arch linux
	$ sudo apt-get install python-virtualenv #ubuntu
	```

	# This is the new style way of declaring classes and should be preferred
	# Python screwed up the way classes and typing works the first go round,
	# but they fixed it with new style classes
	class Object(object):
	# This is the constructor. It takes an instance of the object and a single argument called foo.
	def __init__(self, foo):
	# Make foo a property of this instance
	self.foo = foo
	# Add n to foo. Note that if foo is a string, n must also be a string,
	# or if foo is a numeric type, foo must also be numeric

	import json
	import requests
	from requests.auth import HTTPBasicAuth
	from sys import argv

	url = "https://tickets.puppetlabs.com/rest/api/2/issue/{jira_issue_number}/remotelink"
	headers = {'Content-type': 'application/json'}
	auth = HTTPBasicAuth('ian.kronquist', 'your jira password')

	vagrant@debian-8-jessie-puppet:~$ puppet agent -t --server=192.168.33.10
	Info: Creating a new SSL key for debian-8-jessie-puppet.vagrantup.com
	Info: Caching certificate for debian-8-jessie-puppet.vagrantup.com
	Error: Could not request certificate: The certificate retrieved from the master does not match the agent's private key.
	Certificate fingerprint: 44:4D:D3:60:37:E1:1C:3A:91:0F:CB:DD:9B:3B:F8:3A:38:00:A4:3B:56:88:13:D4:E0:F5:77:E7:5F:FF:0D:CD
	To fix this, remove the certificate from both the master and the agent and then start a puppet run, which will automatically regenerate a certficate.
	On the master:
	puppet cert clean debian-8-jessie-puppet.vagrantup.com
	On the agent:
	1a. On most platforms: find /home/vagrant/.puppet/ssl -name debian-8-jessie-puppet.vagrantup.com.pem -delete
