Refresher - Seven Fundemental Principles of Design

1. Discoverability Makes it easy to understand where to perform actions For example clear focal points (call to actions, images and headers), visual hiearchy (content structured in order of priority), obvious navigation systems all constitute to good discoverability.

2. Feedback Communicates response to our actions When interacting with a product or interface we need some way to communicate the result of our actions. Without any immediate feedback, we are left wondering whether our action has had an impact. Good feed must be immediate, informative, planned (unobstrusive) and prioritized.

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)
