Intro

The point of this test is purely to ensure that we are in fact seeing fairly stabile values when nothing is happening on the laptop.

Transform the data

dirname = "/Users/me/Sites/personal/energy_efficiency/recordings/raw/motionmark/"

sets =
  dirname
  |> File.ls!()
  |> Enum.map(fn filename ->
    set =
      "#{dirname}/#{filename}"
      |> File.read!()
      |> String.trim()
      |> String.split("\n")
      |> Enum.with_index(1)
      |> Enum.map(fn {line, i} ->
        line
        |> String.split(", ")
        |> Enum.map(fn val -> Integer.parse(val) |> elem(0) end)
        |> then(fn [timestamp, value] -> %{"timestamp" => timestamp, "mW" => value} end)
        |> Map.put("label", Path.rootname(filename))
        |> Map.put("index", i)
