This is a simple snippet for adding a loading screen to a Polymer application. It is useful if your Polymer application is rather large and some users may be on a very slow internet connection.

The basic idea is that a very simple (and small) loading screen page will be loaded by the browser. When the browser has fully loaded and displayed the loading page then it will start loading all the files required for the Polymer application.

For a further speed improvement: the loading.css, and polymerAppLoader.js files can be placed inline with the index.html thus reducing the amount of files to be loaded from the server.

filestoload.html is a seperate file so that the usual grunt/gulp build functions can still be applied as before. Shouldn't require re-writting your build scripts.

Any improvements/comments are encouraged.

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.

Create a runner shell script in host -> init with:

• 2GB RAM
• Host CPU with 2 Cores
• Localhost port 2222 traffic redirect to guest port 22
• Spice display with copy and paste enabled
