I FIGURED IT OUT!
  def self.bloat(input, output, size=256)
    if(size < 20)
      raise NeedsMoreBloatException
    end
    n = size - 32 - Math.log2(size).to_i
    key = SecureRandom.hex(15)
    text = SecureRandom.hex(n)[1..n]
    self.insert_text_element(input, output, key, text)
  end
Math.log2(size).to_i
log2 isn't a method within class Math
I wonder if he means like log*2
or something
