Ruby Double Splat is a bit like Javascript Spread
a = { a: "a" }
b = { b: "b" }
{ **a, **b }
#=> {:a=>"a", :b=>"b"}
{ z: "z", **a, **b }
#=> {:z=>"z", :a=>"a", :b=>"b"}
{ a: "AAA", **a, **b }

The Perfect Margarita

The Perfect Margarita

This is my "go to" margarita because of the ease of preparation and the simplicity of ingredients.

TL;DR

1oz orange liqueur, 2oz tequila, 3oz limeade, 1/2 lime, shaken with ice.

Chargify Webhook Reflector. Sinatra app I use in dev to get warm fuzzies as the webhooks fly by. Since Chargify will only post to ports 80 or 443 in production, you'll need to run this on a web accessible box on one of those ports. http://docs.chargify.com/webhooks
require 'sinatra'
require 'openssl'
require 'json'
post '/' do
body = request.body.read
puts "Time : #{Time.now}"
puts "Actual Signature : #{request.env['HTTP_X_CHARGIFY_WEBHOOK_SIGNATURE_HMAC_SHA_256']}"
puts "Computed Signature: #{signature(body)}"

OpenConnect VPN on Mac OS X

Unfortunately, the Cisco AnyConnect client for Mac conflicts with Pow. And by "conflicts", I mean it causes a grey-screen-of-death kernel panic anytime you connect to the VPN and Pow is installed.

As an alternative, there is OpenConnect, a command-line client for Cisco's AnyConnect SSL VPN.

Here's how to get it set up on Mac OS X:

  1. OpenConnect can be installed via homebrew:

     brew update

brew install openconnect

Toying around with an RSpec DSL for permutations. My real use case is more complex than this example - the large numbers of inputs and outputs makes it more concise to "demonstrate" correctness and expectations than to "spec" it out with traditional, one
describe Address do
permute "validations" do
cases [
[:address, :address_2, :city, :state, :zip, :country, :valid, :errors_on],
[ nil, nil, nil, nil, nil, nil, false, ['address', 'city', 'state', 'zip', 'country']],
