  1. "IT'S ONE THING TO TALK ABOUT THEM AND HAVE STORYBOARDS

    AND ANOTHER THING TO SEE THEM FOR REAL.“ ROBERT HOEKMAN, JR.
  2. NÃO PERCA TEMPO COM O MELHOR CÓDIGO, ELE É DESCARTÁVEL

    E SOFRERÁ MUITAS ALTERAÇÕES. NÃO PRECISA FUNCIONAR NO IE6, NEM TER UM BOM HTML. PODE ATÉ USAR TABELA.
  3. MICROFRAMEWORK • Esqueleto da aplicação • Controllers (MVC) – Rotas

     Ações – Requests  Responses • Simples
  4. MICROFRAMEWORK • Ruby  Sinatra, Cuba • Python  Flask,

    Pyramid • PHP  Silex, Slim, Flight • Java  Napalm
  5. SILEX • Não é o Symfony2 • PHP 5.3 •

    PSR-0 • PSR-1 (?) • PSR-2 (?) • Conciso, extensível e testável

  9. SERVICES PROVIDERS • Validator • Form • Monolog • Doctrine

    • Translation • E você pode fazer o seu. Basta implementar uma interface.
