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) *

Elixir + Phoenix Framework + Guardian + JWT + Comeonin

Preparing environment

We need to generate secret key for development environment.

mix phoenix.gen.secret
# ednkXywWll1d2svDEpbA39R5kfkc9l96j0+u7A8MgKM+pbwbeDsuYB8MP2WUW1hf

Let's generate User model and controller.

Shortcut for Syntax Highlighting in Keynote

The idea is based on a gist by @jimbojsb.

You can use Pygments or Highlight.

Install Pygments

brew install python

-- Firstly, remove PRIMARY KEY attribute of former PRIMARY KEY
ALTER TABLE <table_name> DROP CONSTRAINT <table_name>_pkey;

-- Then change column name of  your PRIMARY KEY and PRIMARY KEY candidates properly.
ALTER TABLE <table_name> RENAME COLUMN <primary_key_candidate> TO id;

Every so often I have to restore my gpg keys and I'm never sure how best to do it. So, I've spent some time playing around with the various ways to export/import (backup/restore) keys.

Method 1

Backup the public and secret keyrings and trust database

cp ~/.gnupg/pubring.gpg /path/to/backups/
cp ~/.gnupg/secring.gpg /path/to/backups/
cp ~/.gnupg/trustdb.gpg /path/to/backups/

or, instead of backing up trustdb...

	## get interface name (ovs_eth0 below) via ip link
	ip link add macvlan0 link ovs_eth0 type macvlan mode bridge
	##192.168.4.204/30 (204-207)
	ip addr add 192.168.4.204/30 dev macvlan0
	ip link set macvlan0 up
	ip route add 192.168.44.204/30 dev macvlan0

	docker network create frontend

	For a safe and fast Erlang SSL server, there's a few
	configuration values you might want by default:

	[{ciphers, CipherList}, % see below
	{honor_cipher_order, true}, % pick the server-defined order of ciphers
	{secure_renegotiate, true}, % prevent renegotiation hijacks
	{client_renegotiation, false}, % prevent clients DoSing w/ renegs
	{versions, ['tlsv1.2', 'tlsv1.1']}, % add tlsv1 if you must

	#!/usr/bin/expect -f
