Introduction

An introduction to curl using GitHub's API.

The Basics

Makes a basic GET request to the specifed URI

curl https://api.github.com/users/caspyin

Resize a Hard Disk for a Virtual Machine

Our Virtual Machines are provisioned using Vagrant from a Linux base box to run using VirutalBox. If the Hard Disk space runs out and you cannot remove files to free-up space, you can resize the Hard Disk using some VirtualBox and Linux commands.

Some assumptions

The following steps assume you've got a set-up like mine, where:

Install Apache Spark (OSX)

$ brew install apache-spark

Run the Spark python shell

A python shell with a preconfigured SparkContext (available as sc). It is

	#!/bin/bash
	echo "Generating an SSL private key to sign your certificate..."
	openssl genrsa -des3 -out myssl.key 1024

	echo "Generating a Certificate Signing Request..."
	openssl req -new -key myssl.key -out myssl.csr

	echo "Removing passphrase from key (for nginx)..."
	cp myssl.key myssl.key.org
	openssl rsa -in myssl.key.org -out myssl.key

	#! /usr/bin/env python2
	'''
	Register a mDNS/DNS-SD alias name for your computer using the Avahi daemon

	This script will register an alternate CNAME alias besides your hostname,
	which could be useful for ex. when serving several http virtual hosts to
	your ffriends on the local network and you don't want to make them configure
	their /etc/hosts.

	Why a CNAME? You could also publish your current address with avahi-publish-address

	#!/bin/bash
	#
	# Whitelist Pingdom probe-servers in iptables.
	#
	# Create a chain called "PINGDOM" and jump to it somewhere before
	# the final REJECT/DROP, e.g.
	#
	# # New chain for Pingdom rules
	# :PINGDOM - [0:0]
	#

	#!/bin/bash
