@robwormald welcome! honored to speak to you. If you like Redux, well, SAM is the correct semantics that Redux should have had. It tried to speak to Dan about it, but he never replied to me. SAM's semantics are based on TLA+ so you can't find a more robust formalism.

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096

Quicktime + Hangouts Recording

Scenario: You want to talk with someone over google hangouts (like for a user study), and you want to record BOTH:

	version: 0.0
	os: linux
	files:
	- source: /
	destination: /home/ec2-user/node
	permissions:
	- object: /home/ec2-user
	owner: ec2-user
	group: ec2-user
	type:

	fn main() {

	let closure_immutable_pure = \|x: i32\| x + 1;

	let result1 = apply_pure(& closure_immutable_pure, 1);
	// let result2 = apply_mut(&mut closure_immutable_pure, 2); // not typeable
	let result3 = apply_once(closure_immutable_pure, 3);

	let mut closure_mutable_pure = \|x: i32\| x + 1;

	I inlined the code from microAjax there, to keep dependencies at 0. I think the following cite satisfies the license?

	This code was referenced extensively:
	https://bitbucket.org/snippets/jdubray/9dgKp/sam-sample

	On linux, shebang accepts only one argument.
	As we use nvm we can't adress node executable by path and have to resort to /usr/bin/env.
	Unfortunately `#!usr/bin/env node --harmony` won't work since it needs 2 arguments ...

	This [article](http://sambal.org/2014/02/passing-options-node-shebang-line/) proposes a hack.
	The content of the article is copied below.

	function preprocess(input) {

	const asyncWrapper = (code, binder) => {
	let assign = binder ? `global.${binder} = ` : '';
	return `(function(){ async function _wrap() { return ${assign}${code} } return _wrap();})()`;
