"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.
