5. Realizaré experimentos antes de proseguir, ya que mi
intención es citar experiencias primero, y después
probar mediante el razonamiento por qué dichas
experiencias han de operar de tal modo. Y esta es la
verdadera regla por la que deben proceder aquellos
que especulan acerca de los efectos de la naturaleza.
Leonardo da Vinci

30. Rails is the most well thought-out web development
framework I've ever used.And that's in a decade of

own frameworks, helped develop the ServletAPI,
and have created more than a few web servers from
scratch. Nobody has done it like this before.
