- Slides com temas, cores e efeitos são muito legais mas, a menos que você saiba exatamente como isso vai ficar no projetor, deixe a “tentação” de lado e faça o simples: slide branco, texto preto
- Para código fonte, independente de conhecer ou não o lugar onde será apresentado, sempre utilize fundo branco, texto em tamanho grande (22 ou maior) e um tema como esse: http://yfrog.com/735mfp
- Se utiliza um Mac, uma forma fácil de copiar código fonte com syntax highlighting para os slides é usar o editor TextMate e um bundle chamado Copy as RTF
- Também no Mac, quando conectado ao projetor, é possível modificar o color profile da saída de vídeo, buscando obter uma reprodução mais fiel ao seu monitor. Para isso, após conectado, acesse System Preferences > Displays > Color (aba na janela de configurações do display secundário) e selecionar um profile que se adeque bem
- Como último recurso, é possível inverter as co

# Rails developers have long had bad experiences with fixtures for | |
# several reasons, including misuse. | |
# | |
# Misuse of fixtures is characterized by having a huge number of them, | |
# requiring the developer to maintain a lot of data and creating dependencies | |
# between tests. In my experience working (and rescuing) many applications, 80% | |
# of fixtures are only used by 20% of tests. | |

# An example of such tests is one assuring that a given SQL query with | |
# GROUP BY and ORDER BY conditions returns the correct result set. As expected, |

# MOTIVATION: As rails apps are growing, people are noticing the drawbacks | |
# of the ActiveRecord pattern. Several apps I have seen, and several | |
# developers I have spoken to are looking towards other patterns for object | |
# persistence. The major drawback with ActiveRecord is that the notion | |
# of the domain object is conflated with what it means to store/retrieve | |
# it in any given format (like sql, json, key/value, etc). | |
# | |
# This is an attempt to codify the Repository pattern in a way that would | |
# feel comfortable to beginner and seasoned Ruby developers alike. | |
