Introduction

I wrote this gist to record the steps I followed to get docker running in my Raspberry Pi 3. The ARM ported debian version (Jessie) comes with an old version of docker. It is so old that the docker hub it tries to interact with doesn't work anymore :)

Hopefully this gist will help someone else to get docker running in their Raspberry Pi 3.

Installation

Let's Encrypt

Examples of getting certificates from Let's Encrypt working on Apache, NGINX and Node.js servers.

Obtain certificates

I chose to use the manual method, you have to make a file available to verify you own the domain. Follow the commands from running

git clone https://github.com/letsencrypt/letsencrypt
cd letsencrypt

@kangax's ES6 quiz, explained

@kangax created a new interesting quiz, this time devoted to ES6 (aka ES2015). I found this quiz very interesting and quite hard (made myself 3 mistakes on first pass).

Here we go with the explanations:

Question 1:

(function(x, f = () =&gt; x) {

Hi Nicholas,

I saw you tweet about JSX yesterday. It seemed like the discussion devolved pretty quickly but I wanted to share our experience over the last year. I understand your concerns. I've made similar remarks about JSX. When we started using it Planning Center, I led the charge to write React without it. I don't imagine I'd have much to say that you haven't considered but, if it's helpful, here's a pattern that changed my opinion:

The idea that "React is the V in MVC" is disingenuous. It's a good pitch but, for many of us, it feels like in invitation to repeat our history of coupled views. In practice, React is the V and the C. Dan Abramov describes the division as Smart and Dumb Components. At our office, we call them stateless and container components (view-controllers if we're Flux). The idea is pretty simple: components can't

	import React from 'react'
	import { withRouter, Link } from 'react-router-dom'
	import { graphql, compose } from 'react-apollo'
	import { Formik } from 'formik'
	import Yup from 'yup'

	import FormWideError from '../elements/form/FormWideError'
	import TextInput from '../elements/form/TextInput'
	import Button from '../elements/form/Button'
	import { H2 } from '../elements/text/Headings'

	# The reason of creating this script is that Endpoint Security VPN installs it's own application firewall kext cpfw.kext
	# which prevents for example PPTP connections from this computer, which is not appropriate if you need subj connection just
	# from time to time
	#
	# Usage: ./checkpoint.sh
	#
	# The script checks if Enpoint Security VPN is running. If it is, then it shuts it down, if it is not, it fires it up.
	# Or, make an Automator action and paste the script.
