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?

Managing OpenStack instances with Ansible through an SSH bastion host

I'm be using DreamCompute as my OpenStack provider, but there are dozens to choose from. I assume you already have Ansible and the OpenStack CLI tools installed.

Motivation

With the proliferation of OpenStack public clouds offering free and intro tiers, it's becoming very easy to effectively run a simple application for free or nearly free. Also with the emergence of Ansible, you don't need to learn and deploy complicated tools to do configuration management.

I no longer mantain this list. There are lots of other very comprehensive JavaScript link lists out there. Please see those, instead (Google "awesome JavaScript" for a start).
