Notes

  1. Sync vs Async
    • JS executes code in a synchronous manner one function at a time one statement at a time
    • JS is single threaded
      • that means only one statement is executed at a time.
    • Asynchronous mean two or more things happening at a time. In JS that means deferring remaining execution of a function
      • We need this because some operation can take be very slow:

  1. What is ES6
  2. Let & Const
    • uses block scoping
    • const cannot be reassigned
    • not hoisted
  3. Arrow Functions
    • uses block scoping
    • implied this value assignment
    • no prototype
  • The real purpose of arrow functions is to handle the THIS keyword withing nested / callback functions

Install PostgreSQL 10 on Ubuntu

Install PostgreSQL 10 on Ubuntu

This is a quick guide to install PostgreSQL 10 - tested on Ubuntu 16.04 but likely can be used for Ubuntu 14.04 and 17.04 as well, with one minor modification detailed below.

(Optional) Uninstall other versions of postgres

To make life simple, remove all other versions of Postgres. Obviously not required, but again, makes life simple. If you have data in your previous version of postgres that you'd like to retain, then this is not recommended. Instead, you'll have to use pg_upgrade or pg_upgradecluster.
