Be Careful with Table Driven Tests and `t.Parallel()`

We Gophers, love table-driven-tests, it makes our unittesting structured, and makes it easy to add different test cases with ease.

Let’s create our table driven test, for convenience, I chose to use t.Log as the test function. Notice that we don't have any assertion in this test, it is not needed to for the demonstration.

func TestTLog(t *testing.T) {
	t.Parallel()

Principles of Adult Behavior

Be patient. No matter what.
Don’t badmouth: Assign responsibility, not blame. Say nothing of another you wouldn’t say to him.
Never assume the motives of others are, to them, less noble than yours are to you.
Expand your sense of the possible.
Don’t trouble yourself with matters you truly cannot change.
Expect no more of anyone than you can deliver yourself.
Tolerate ambiguity.
Laugh at yourself frequently.

Production Ready Process Monitoring

Install docker-manger.conf and docker-instance.conf in /etc/init
Create a containers file in /etc/docker/ with the following format
```
 name: image cmd
```
The name must be unique.
sudo service docker-manager start

	#!/bin/bash

	# Generate a `:something-intensifies:` Slack emoji, given a reasonable image
	# input. I recommend grabbing an emoji from https://emojipedia.org/

	set -euo pipefail

	# Number of frames of shaking
	count=10
	# Max pixels to move while shaking

	# In order for gpg to find gpg-agent, gpg-agent must be running, and there must be an env
	# variable pointing GPG to the gpg-agent socket. This little script, which must be sourced
	# in your shell's init script (ie, .bash_profile, .zshrc, whatever), will either start
	# gpg-agent or set up the GPG_AGENT_INFO variable if it's already running.

	# Add the following to your shell init to set up gpg-agent automatically for every shell
	if [ -f ~/.gnupg/.gpg-agent-info ] && [ -n "$(pgrep gpg-agent)" ]; then
	source ~/.gnupg/.gpg-agent-info
	export GPG_AGENT_INFO
	else
