// Implement Pic. It should return a slice of length dy, each element of which is 
// a slice of dx 8-bit unsigned integers. When you run the program, it will display your picture, 
// interpreting the integers as grayscale (well, bluescale) values.
//
// The choice of image is up to you. Interesting functions include (x+y)/2, x*y, and x^y.
//
// (You need to use a loop to allocate each []uint8 inside the [][]uint8.)
//
// (Use uint8(intValue) to convert between types.)

Managing OpenStack instances with Ansible through an SSH bastion host

I'm be using DreamCompute as my OpenStack provider, but there are dozens to choose from. I assume you already have Ansible and the OpenStack CLI tools installed.

Motivation

With the proliferation of OpenStack public clouds offering free and intro tiers, it's becoming very easy to effectively run a simple application for free or nearly free. Also with the emergence of Ansible, you don't need to learn and deploy complicated tools to do configuration management.
