The original author seems to be Charles Edge, here's the original content, as pointed out by @percisely.

Note: Since this seems to be helpful to some people, I formatted it to improve readability of the original. Also, note that this is from 2016, many things may have changed, and I don't use macOS anymore, so I probably can't help in case of questions, but maybe someone else can.

Mac Network Commands Cheat Sheet

After writing up the presentation for MacSysAdmin in Sweden, I decided to go ahead and throw these into a quick cheat sheet for anyone who’d like to have them all in one place. Good luck out there, and s

An Alexa skill may ask a user a Yes/No question and the response handled by request handlers for the built-in AMAZON.YesIntent and AMAZON.NoIntent intents. (This is different than dialog confirmation where Yes/No confirmation is handled by the dialog.)

It’s easy to setup these intents and their respective intent handlers. Just like any intent, declare them in the interaction model:

{
  "name": "AMAZON.YesIntent",
  "samples": []
},

	module "combined_acm_certificate" {
	source = "../../modules/acm_certificate_dns_validated_multi_zone"

	domain_name = "infra.example.com"
	zone_to_san = {
	"infra.example.com" = [
	"*.infra.example.com",

	"*.production.infra.example.com",

	#!/bin/sh

	# Generate self signed root CA cert
	openssl req -nodes -x509 -newkey rsa:2048 -keyout ca.key -out ca.crt -subj "/C=AU/ST=NSW/L=Sydney/O=MongoDB/OU=root/CN=`hostname -f`/[email protected]"


	# Generate server cert to be signed
	openssl req -nodes -newkey rsa:2048 -keyout server.key -out server.csr -subj "/C=AU/ST=NSW/L=Sydney/O=MongoDB/OU=server/CN=`hostname -f`/[email protected]"

	# Sign the server cert

	export PS1="\[\033[36m\]\u\[\033[m\]@\[\033[32m\]\h:\[\033[33;1m\]\w\[\033[m\] git:(\$(git symbolic-ref HEAD 2> /dev/null \| sed 's/refs\/heads\///g')) "

	When executing interactively, bash displays the primary
	prompt PS1 when it is ready to read a command, and the
	secondary prompt PS2 when it needs more input to complete
	a command. Bash allows these prompt strings to be cus
	tomized by inserting a number of backslash-escaped special
	characters that are decoded as follows:
	\a an ASCII bell character (07)
	\d the date in "Weekday Month Date" format

	// a list of useful queries for profiler analysis. Starting with the most basic.
	// 2.4 compatible

	// output explained:

	"op" : "query", // the operation type
	"ns" : "game.players", // the db and collection

	So in the README.md I put instructions https://github.com/jbelmont/nosql-workshop/blob/master/README.md

	Please make sure you have installed docker in your machine.

	Then pull down mongo image with following command:

	Install my mongo image:

	docker pull jbelmont/nosql-mongo-image-with-scripts:v1
