When working through unknown code method, ask:

What does a given method do?
What is the current object context that I am in?
What other methods can I call here?

module Purchasable
  def purchase
    result = Braintree::Transaction.sale(amount: total, credit_card: card)

module Saran

  # Makes http requests.
  class Endpoint
    attr_reader :verb, :path, :provider, :endpoint, :access_token

    # TODO: remove config dependency,
    #       can combine path, endpoint, access_token
    #         depends on if OpenAuth can deal with full_url
    #       how to deal with provider?

Your apps starts great and you love working with it up until beta when it becomes a mess and you hate it.

Your app is made up of things and know things about themselves and about others. The latter is dependencies. When the dependencies change, the object will need to change as well.

OO design makes you write code that your future self will love. Stop worrying and learn to love the mess.

On stressful days many of us give in to temptation and choose unhealthy options.

Six steps to avoid breaking unders stress

1. Acknowledge the tension, don't ignore it - we use self control every time we force ourself to make the good, reasonable decision, and that self control, like other human capacities is limited.

2. Call it what it is: ego depletion - depletion is the psychological sum of these feelings, of all the decisions you made that led to that moment.

3. Understand ego-depletion - people under greater cognitive strain were less able to overturn their instintive desires.

Manager's schedule:
  Traditional appointment book.
  Each day cut into one hour intervals.
  By default you've to change what you're doing each hour.

Maker's schedule:
  Prefer longer units of time, at least half a day.
  Can't work/switch every hour, barely enough time to get started.

Q. What is polymorphism?
* Allows values of different data types to be handled using an uniform interface.
* 3 types:
  * Overloading: Methods of same name exists in different class.
      Ex: + method operates differently for integers and floats.
  * Parametric: Methods of same name, but accept diff. parameters.
  * Inclusion: The ability to redefine methods in inherited classes.

Interfaces vs. Duck typing

Duck typing isn't really about checking whether the things you need are there and then using them.
Duck typing is about just using what you need.

Interfaces are named collections of method signatures.
