IDEIAS NÃO VALEM NADA!
Etapas pra produzir sua ideia: 1. Ideia 2. Documentação 3.
Mockups 4. Protótipos 5. Vídeos
POR QUE PROTOTIPAR?
None
"IT'S ONE THING TO TALK ABOUT THEM AND HAVE STORYBOARDS
AND ANOTHER THING TO SEE THEM FOR REAL.“ ROBERT HOEKMAN, JR.
None
POR MELHOR QUE VOCÊ SEJA, SEMPRE COMETERÁ ERROS.
VOCÊ NÃO PRECISA FAZER TUDO, SOMENTE O PRINCIPAL.
TERMINE O PROTÓTIPO EM 1 DIA.
ITERAÇÕES: REESTUDE O PROBLEMA, REPENSE A SOLUÇÃO.
NÃO PERCA TEMPO COM O MELHOR CÓDIGO, ELE É DESCARTÁVEL
E SOFRERÁ MUITAS ALTERAÇÕES.
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.
MICROFRAMEWORK
MICROFRAMEWORK • Esqueleto da aplicação • Controllers (MVC) – Rotas
Ações – Requests Responses • Simples
MICROFRAMEWORK • Ruby Sinatra, Cuba • Python Flask,
Pyramid • PHP Silex, Slim, Flight • Java Napalm
SILEX
SILEX • Não é o Symfony2 • PHP 5.3 •
PSR-0 • PSR-1 (?) • PSR-2 (?) • Conciso, extensível e testável
COMO USAR
1 { 2 "require": { 3 "php": ">=5.3.2", 4 "silex/silex":
"*" 5 } 6 } 1 curl -s http://getcomposer.org/installer | php 2 php composer.phar install composer.json shell

SERVICES PROVIDERS • Validator • Form • Monolog • Doctrine
• Translation • E você pode fazer o seu. Basta implementar uma interface.
