Cheat Sheets are greate but they are not a substitute for learning the framework and reading the documentation as we most certainly have not covered every potential example here. Please refer to the Rails Command Line Docs for more information.

Command Line Generator Info

Reference

You can get all of this information on the command line.

rails generate with no generator name will output a list of all available generators and some information about global options. rails generate GENERATOR --help will list the options that can be passed to the specified generator.

Exporting your 2FA tokens from Authy to transfer them into another 2FA application

IMPORTANT - Update regarding deprecation of Authy desktop apps

Past August 2024, Authy stopped supported the desktop version of their apps:
See Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August for details.

And indeed, after a while, Authy changed something in their backend which now prevents the old desktop app from logging in. If you are already logged in, then you are in luck, and you can follow the instructions below to export to tokens.

If you are not logged in anymore, but can find a backup of the necessary files, then restore those files, and re-install Authy 2.2.3 following the instructions below, and it should work as expected.

These are my notes for connecting to a meraki client vpn from ubuntu 16.04. This configuration assumes you are using a psk for the ipsec auth.

Install the following packages:

apt-get install -y strongswan xl2tpd

Configure strong swan

Problem: When linking to the raw version of a gist, the link changes with each revision.

Solution:

To return the first file from a gist: https://gist.github.com/[gist_user]/[gist_id]/raw/

Example: https://gist.github.com/atenni/5604522/raw/
Works even when you change the filename.

To get a file from multi–file gist: https://gist.github.com/[gist_user]/[gist_id]/raw/[file_name]

	// Installation:
	// 1. Save this file as /Users/YOUR_USER_NAME_HERE/Library/KeyBindings/DefaultKeyBinding.dict
	// 2. Log out and log back in (or just restart any app where you'd like to use the shortcut)

	// What: Keyboard shortcut to easily insert checkmarks. (Or whatever text you'd like to insert).
	// By default option+v in MacOS inserts a square-root symbol: √
	// I've often used option+v as a quick-and-dirty checkmark. This shortcut lets me get a real checkmark.

	{
	// Insert a checkmark with option+v

	// Step 1: Get an API key here: https://developers.google.com/url-shortener/v1/getting_started#APIKey
	// Step 2: Paste your api key below
	// Step 3: Add the code below to your browser as a bookmark
	// Step 4: Visit a non-goo.gl URL and click your bookmark

	// NOTE: The security policy of some sites (such as this gist.github.com!) will prevent this from working.
	// Check your javascript console if something doesn't work.

	# To Setup:
	# 1) Save the .git-completion.bash file found here:
	# https://github.com/git/git/blob/master/contrib/completion/git-completion.bash
	# 2) Add the following lines to your .bash_profile, be sure to reload (for example: source ~/.bash_profile) for the changes to take effect:

	# Git branch bash completion
	if [ -f ~/.git-completion.bash ]; then
	. ~/.git-completion.bash

	# Add git completion to aliases

	require 'securerandom'
	length = 10
	SecureRandom.random_number(36 ** length).to_s(36) # Base 36, ie. 0..9 + a..z
	# => "9datwwkqlo"

	#! /usr/bin/env ruby

	require 'bundler'

	paths = Bundler.load.specs.map(&:full_gem_path)
