Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

Follow standard conventions.
Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
Boy scout rule. Leave the campground cleaner than you found it.
Always find root cause. Always look for the root cause of a problem.

Docker Cli Tips and Tricks

My favorite command line options and best practices

Bash/zsh completion
use Tab to populate command line, narrows down options as you go, fills in container names, ID's, images, volumes. Huge time saver.

	#!/bin/bash

	usage() { echo "usage: --coursename [--coursename \"build-a-react-app-with-redux\"] --type [--type \"courses\|lessons\"]" 1>&2; exit 1; }

	OPTS=$(getopt -o c:t: --long coursename:,type: -n 'download_egghead_videos.sh' -- "$@")

	if [ $? != 0 ] ; then echo "Terminating..." >&2 ; exit 1 ; fi

	eval set -- "$OPTS"

	.ReactTable {
	position: relative;
	display: -webkit-box;
	display: -ms-flexbox;
	display: flex;
	-webkit-box-orient: vertical;
	-webkit-box-direction: normal;
	-ms-flex-direction: column;
	flex-direction: column;
	border: 1px solid rgba(0, 0, 0, 0.1);

	# Use hyper.is or iTerm2 as terminal emulators

	# Install ohmyzsh
	# https://github.com/robbyrussell/oh-my-zsh

	# Copy over configs from ~/.bash_profile
	# For example, it may have the nvm setup or any aliases like exa=ls and cat=bat

	# ~/.hyper.js configuration:
	copyOnSelect: true

	// Add a 401 response interceptor
	window.axios.interceptors.response.use(function (response) {
	return response;
	}, function (error) {
	if (401 === error.response.status) {
	swal({
	title: "Session Expired",
	text: "Your session has expired. Would you like to be redirected to the login page?",
	type: "warning",
	showCancelButton: true,

	import React, { Component } from 'react'
	import { Redirect } from 'react-router'

	export default class ContactForm extends Component {
	constructor () {
	super();
	this.state = {
	fireRedirect: false
	}
	}
