gpg-agent setup

Need to setup gpg-agent first, on OSX I use keychain (it also does ssh-agent)

$ brew info keychain
keychain: stable 2.8.5
User-friendly front-end to ssh-agent(1)
https://www.funtoo.org/Keychain
/usr/local/Cellar/keychain/2.8.5 (7 files, 108.5KB) *

FWIW: I (@rondy) am not the creator of the content shared here, which is an excerpt from Edmond Lau's book. I simply copied and pasted it from another location and saved it as a personal note, before it gained popularity on news.ycombinator.com. Unfortunately, I cannot recall the exact origin of the original source, nor was I able to find the author's name, so I am can't provide the appropriate credits.

	After automatically updating Postgres to 9.6.1 via Homebrew, the pg_ctl start command didn't work.
	The error was something like "database files are incompatible with server".

	Database files have to be updated before starting the server, here are the steps that had to be followed:

	# need to have both 9.6.1 and latest 9.5.x installed, and keep 9.6.1 as default
	brew unlink postgresql
	brew install postgresql95
	brew unlink postgresql95
	brew link postgresql

	#!/bin/bash

	TABLE_NAME=$1

	# Get id list
	aws dynamodb scan --table-name $TABLE_NAME \| grep ID \| awk '{ print $2 }' > /tmp/truncate.list

	# Delete from id list
	cat /tmp/truncate.list \| xargs -IID aws dynamodb delete-item --table-name $TABLE_NAME --key '{ "id": { "S": "ID" }}'
