58 bytes of CSS to look great nearly everywhere

When making this website, i wanted a simple, reasonable way to make it look good on most displays. Not counting any minimization techniques, the following 58 bytes worked well for me:

main {
  max-width: 38rem;
  padding: 2rem;
  margin: auto;
}

def create_batch(conn, %{"people" => people_params}) do
  changesets = Enum.map(people_params, fn class ->
    Person.changeset(%Person{}, person)
  end)

  result = changesets
           |> Enum.with_index()
           |> Enum.reduce(Ecto.Multi.new(), fn ({changeset, index}, multi) ->
              Ecto.Multi.insert(multi, Integer.to_string(index), changeset)
           end)

# two different ways to implement a find_or_create for Ecto

find_or_create_user = fn user ->
  case Repo.all(from u in users, where: u.id == ^user.id and u.email == ^user.email) do
    [] ->
      %User{}
      |> User.changeset(user)
      |> Repo.insert!()
    _ ->
      IO.puts "Already inserted"

Deploying Elixir and Phoenix applications using Docker and Exrm

Goal

By the end of this quick guide, you will know how to compile a Phoenix app release using Exrm and run it inside a Docker container. I've found only a couple of articles that discuss getting an Elixir app up and running inside a Docker container, and even those only touched on some parts of the process. The idea is that this guide will give you a full end-to-end example of how to get all the pieces and parts working together so that you are able to deploy your Phoenix application inside a Docker container.

Assumptions

1. You already have a working Elixir environment with the Phoenix Framework installed
2. You have at least basic working knowledge of Docker, and have installed the Docker tools onto your local environment

Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.
