Some throwaway code I used to demonstrate the blowfish cipher with the PyCrypto library

	# Sample code by Mark Nenadov.
	#
	# Warning, this is OLD legacy code. It hasn't been tested in semi recent versions
	# of Python or PyCrypto.
	#
	# You may use this however you wish, but I retain no responsibility whatsoever for how
	# you use it and provide it with no warranty, either.


	from Crypto.Cipher import Blowfish

AWS, JQ and bash command cheat sheet. How to query, cut and munge things in JSON generally.

	# Count total EBS based storage in AWS
	aws ec2 describe-volumes \| jq "[.Volumes[].Size] \| add"
	# Count total EBS storage with a tag filter
	aws ec2 describe-volumes --filters "Name=tag:Name,Values=CloudEndure Volume qjenc" \| jq "[.Volumes[].Size] \| add"
	# Describe instances concisely
	aws ec2 describe-instances \| jq '[.Reservations \| .[] \| .Instances \| .[] \| {InstanceId: .InstanceId, State: .State, SubnetId: .SubnetId, VpcId: .VpcId, Name: (.Tags[]\|select(.Key=="Name")\|.Value)}]'
	# Wait until $instance_id is running and then immediately stop it again
	aws ec2 wait instance-running --instance-id $instance_id && aws ec2 stop-instances --instance-id $instance_id

	# Get 10th instance in the account
