Using Mailboxes in Elm: a tutorial blog post

Using Mailboxes in Elm

Max Goldstein | July 30, 2015 | Elm 0.15.1

In Elm, signals always have a data source associated with them. Window.dimensions is exactly what you think it is, and you can't send your own events on it. You can derive your own signals from these primitives using map, filter, and merge, but the timing of events is beyond your control.

This becomes a problem when you try to add UI elements. We want to be able to add checkboxes and dropdown menus, and to receive the current state of these elements as a signal. So how do we do that?

Blue-Green AWS Auto Scaling Deployments with Terraform

A quick note on how I'm currently handling Blue/Green or A/B deployments with Terraform and AWS EC2 Auto Scaling.

In my particular use case, I want to be able to inspect an AMI deployment manually before disabling the previous deployment.

Hopefully someone finds this useful, and if you have and feedback please leave a comment or email me.

Overview

I build my AMI's using Packer and Ansible.
