Monads

Monads are a way to chain functions together. Maybe monad (from Haskell) is used to chain functions together when the functions might fail. It assumes:

1. If I have Nothing, stop computing.
2. If I have Something, pass it to next function.
3. That function may return Something or Nothing. Go back to Step 1.

x ||= y # x = y unless x

6. Tech stack - Preferably Rails + MongoDb with a hint of Javascript/Coffeescript. As long as it's not Java.
7. Company culture
