Lesson 1: Affordances and Signifiers

Don't solve the problem given (as it's stated), figure out what the real underlying problem is.

To understand design, you have to be a good observer and question things. Travel with a camera and take photos. Don't use flash, use natural lighting when possible.

Affordances are the relationships (read: possible actions) between an object and an entity (most often a person). For example, a chair affords sitting for a human. Affordances enable interactions between entities and objects (similarly, anti-affordances prevent or reduce interactions). The presence of an affordance is determined by the properties of the object and of the abilities of the entity who's interacting with the object.

Signifiers are signals, communication devices. These signs tell you about the possible actions; what to do, and where to do it. Signifiers are often visible, but invisible (secret) signifiers do exist, like clicking a YT video to play

#System Design Cheatsheet

Picking the right architecture = Picking the right battles + Managing trade-offs

##Basic Steps

1. Clarify and agree on the scope of the system

• User cases (description of sequences of events that, taken together, lead to a system doing something useful)
  • Who is going to use it?
  • How are they going to use it?

# This is sp, the command-line Spotify controller. It talks to a running
# instance of the Spotify Linux client over dbus, providing an interface not
# unlike mpc.
#
# Put differently, it allows you to control Spotify without leaving the comfort
# of your command line, and without a custom client or Premium subscription.
