"The goggles, they do nothing!" `rake db:test:prepare` appears to have become `rake test:prepare` in Rails 4, but the old task still exists and does nothing. http://stackoverflow.com/q/17150529/4937

	$ rake --trace db:test:prepare
	** Invoke db:test:prepare (first_time)
	** Execute db:test:prepare

	$ rake --trace test:prepare

Look at your code. Now back to me. Now back to your code. Now back to me. Your BigDecimals are now readable.

	module ReadableBigDecimal
	def inspect
	"<#{self.class.name}: #{self.to_f}>"
	end
	end

	BigDecimal(10) # => #<BigDecimal:7fcd7103ee68,'0.1E2',9(36)>
	BigDecimal.send(:prepend, ReadableBigDecimal)
	BigDecimal(10) # => #<BigDecimal: 10>

TeeIO: A method for logging to a file and STDOUT at the same time. Or to any two or more IOs. Greatly inspired by James Edward Grey II.

	class TeeIO
	# TeeIO will write to each of these IOs when it is written to.
	def initialize(*ios)
	@ios = ios
	end

	def write(data)
	@ios.each { \|io\| io.write(data) }
	end

Moving STDERR and STDOUT around for great justice.

	# A program which outputs "error" to STDERR and "output" to STDOUT.
	a_program() {
	echo error >&2
	echo output
	}

	# Run a_program.
	# - Redirect a_program's STDERR (file descriptor 2) to the STDIN of a tee process.
	# - tee echoes its STDIN to the given filename and to its STDOUT.
	# - Redirect tee's STDOUT to its STDERR.
