How to use this gist

You've got two main options:

Autobahn App API

Das BMVI hat eine völlig nutzlose App gebaut. Eine Autobahn-Info App.

Wirklich völlig nutzlos?

Nein, es gibt jetzt nämlich eine offene API für aktuelle Verwaltungsdaten in Bezug auf Baustellen-Informationen, Webcams, Parkplätze, … - bestimmt für jemand nützlich.

Endpunkte

Hier gibt es eine OpenAPI Spec von @creckord: https://gist.github.com/creckord/a2e09267f5fdfadc2cd75eedb3182b8a

https://verkehr.autobahn.de/o/autobahn/

Here's an ecto changeset validation for urls:

  @doc """
  validates field is a valid url

  ## Examples
    iex> Ecto.Changeset.cast(%ZB.Account{}, %{"website" => "https://www.zipbooks.com"}, [:website])
    ...> |> Utils.Changeset.validate_url(:website)
    ...> |> Map.get(:valid?)

TL;DR

Create 10GB FreeBSD image using QEMU.
Run the VM using xhyve.
Mount host directory.
Resize the image.

Requisites

OSX
Homebrew

FreeBSD 10 Nodejs setup with nginx, mongodb, redis and monit

This my receipe for installing a complete nodejs server on FreeBSD 10. The parameters used in this configuration are for a very small private server that I use for demo purpose only, so for a production server, you should somehow set the limits in pair with your ressources.

I use monit so I don't have to write rc scripts for node and it should take care of process lifecycle management for me. Alternatives exists such as supervisord or circus.

	# How to use it:
	#
	# Plug it at the end of your :browser pipeline in your Phoenix app router.ex
	# Make sure it is plugged before your session-based authentication and authorization Plugs.
	#
	# pipeline :browser do
	# plug :accepts, ["html"]
	# plug :fetch_session
	# plug :fetch_flash
	# plug :put_secure_browser_headers
