Updating WSL
Updating Packages in WSL
Because WSL uses a standard Ubuntu installation, upgrading your packages should look very familiar:

$ sudo apt-get update
$ sudo apt-get upgrade
Updating the Ubuntu OS

You can aso upgrade to the latest version of Ubuntu with the following command (caution, this will take quite some time)!:

Install PostgreSQL using WSL
This doc explains how to install PostgreSQL 10 for Windows WSL

We are installing this through the Ubuntu command line since we want this software to run in the Linux environmnet. You can check out the PostgreSQL Linux install docs here.

Install
Open a terminal (the Ubuntu app) and then go to the root of the Ubuntu Subsystem by typing cd ~ .
Type sudo nano ../../etc/apt/sources.list. This will open a file on Ubuntu using the Nano editor.
At the bottom of this file, paste in this line deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main
Change the last part of the line above from xenial- to whichever version of Ubunutu you are running.

# The idea is just to illustrate that Ruby's #map and #select Enumerable methods
# are simply specific flavours of a fold operation, which Ruby implements as #inject.
# I've implemented #map and #select using #inject, and at the end I implemented #inject
# recursively. Ruby does #inject with Array#each, for very good reason. The recursive 
# implementation is really just to illustrate the core Functional Programming concept 
# which it derives from.

# We'll start simple.  Map without applying a function:

[1,2,3,4,5].inject([]) {|memo, obj| memo << obj }
