Find the SD card device

In this case, the SD card is /dev/disk4. DO NOT get this wrong or you may destroy all the data on the wrong disk/card/drive.

diskutil list

/dev/disk0
   #:                       TYPE NAME                    SIZE       IDENTIFIER

I'm a fan of MiniTest::Spec. It strikes a nice balance between the simplicity of TestUnit and the readable syntax of RSpec. When I first switched from RSpec to MiniTest::Spec, one thing I was worried I would miss was the ability to add matchers. (A note in terminology: "matchers" in MiniTest::Spec refer to something completely different than "matchers" in RSpec. I won't get into it, but from now on, let's use the proper term: "expectations").

Understanding MiniTest::Expectations

Let's take a look in the code (I'm specifically referring to the gem, not the standard library that's built into Ruby 1.9):

# minitest/spec.rb

module MiniTest::Expectations

	# code inspired from http://jainmarket.blogspot.com/2009/05/creating-custom-table-view-cell.html

	class CustomCell < UITableViewCell

	attr_accessor :primaryLabel
	attr_accessor :secondaryLabel

	def createLabels

	@primaryLabel = UILabel.alloc.init

	require 'router'

	use Rack::CommonLogger
	use Rack::ShowExceptions
	use Rack::Lint
	use Rack::Static, :urls => ["/static"]

	run Router.new

	class QueryTracer < ActiveSupport::LogSubscriber

	ACCEPT = %r{^(app\|config\|lib)}.freeze
	FRAMES = 5
	THRESHOLD = 300 # In ms

	def sql(event)
	return unless event.duration > THRESHOLD
	callers = Rails.
	backtrace_cleaner.
