See https://stackoverflow.com/questions/729692/why-should-text-files-end-with-a-newline

A newline in a text file is a terminator, not a separator. This means each line should have a newline at the end of it, including the last line of the file.

Many editors automatically add the newline at the end of the file. Some do not. If you can configure your editor to ensure there is always a newline at the end of every line, please do so.

Because many editors do add this newline, if you commit a text file without it, when someone else edits the file, their editor will (correctly) add the newline. This causes a spurious diff in the file. Spurious

You can use Ellie to "test" the code, changing only the result function and adding your extra code

How to calculate your hourly rate as a freelancer?

Many people struggle with this question. Some just try to make as much as a full-time employee makes (and ignore that they won't be able to bill as many days). Others follow tips on startup related websites that suggest to ask for 20% to 50% more than an salary would yield (and ignore the additional risk and expenses they have).

Below you will find some numbers to help you calculate how high your hourly or daily rate should be.

Your yearly income should be higher than an average salary

You take more risk than full time employees, phases without income are likely

README

Services declared as oneshot are expected to take some action and exit immediatelly (thus, they are not really services, no running processes remain). A common pattern for these type of service is to be defined by a setup and a teardown action.

Let's create a example foo service that when started creates a file, and when stopped it deletes it.

Define setup/teardown actions

Create executable file /opt/foo/setup-foo.sh:

	<!DOCTYPE html>
	<html lang="en">
	<head>
	<meta charset="UTF-8">
	<meta name="viewport" content="width=device-width, initial-scale=1.0">

	<style>
	body {

	// An Aggregate is a tree of object relations that protect business invariants (business rules).
	// Concretely, an aggregates handle commands and have a state model encapsulated within it that allows
	// it to implement the required command validation, thus upholding the invariants (business rules) of the aggregate.
	// Aggregates are usually composed of several entities and values objects.
	// The lifetimes of the components of an aggregate are bounded by the lifetime of the entire aggregate.
	// Aggregate is abstract concept, it's just represented as an empty interface with no specific contract.
	type Aggregate interface{}

	// Illustrator util to copy layers content to artboards

	// Each layer must contain one single group
	// It will name the artboard to match the layer name
	// For each 20 layers it creates a new row
	// Ensure the original artboard is placed in the top left corner

	// TODO: translate the original artboard on the top left corner
