• Read the top-level Documentation and FAQs for all the major AWS resources (EC2, S3, RDS, Auto Scaling, etc). The answers to the "nit-picky" questions can be found here. It's also helpful to go deeper on VPCs and networking-related concepts.
  • VPC http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/using-vpc.html

Update

If you're looking at this in 2016, I strongly recommend investigating real headless Chrome: https://chromium.googlesource.com/chromium/src/+/lkgr/headless/README.md

#If you're on Ubuntu or working with a Linux VM...

Step 1: Install the Ubuntu dependencies needed:

SSH into your server as a root or do sudo -i.

Redis and Resque

What this guide will cover: the code you will need in order to include Redis and Resque in your Rails app, and the process of creating a background job with Resque.

What this guide will not cover: installing Ruby, Rails, or Redis.

Note: As of this writing I am still using Ruby 1.9.3p374, Rails 3.2.13, Redis 2.6.11, and Resque 1.24.1. I use SQLite in development and Postgres in production.

Background jobs are frustrating if you've never dealt with them before. Over the past few weeks I've had to incorporate Redis and Resque into my projects in various ways and every bit of progress I made was very painful. There are many 'gotchas' when it comes to background workers, and documentation tends to be outdated or scattered at best.

Building OpenConnect 7 on Ubuntu 14 (trusty) and 15 (vivid)

The steps in this guide are available as an autobuild shell script

Why?

Because the OpenConnect package from Ubuntu is a bit outdated, and if you have a recent AnyConnect server, you need a newer OpenConnect to play with it.

Why this guide uses OpenSSL instead of GnuTLS

##Working with ansible-vault

I've been using a lot of Ansible lately and while almost everything has been great, finding a clean way to implement ansible-vault wasn't immediately apparent.

What I decided on was the following: put your secret information into a vars file, reference that vars file from your task, and encrypt the whole vars file using ansible-vault encrypt.

Let's use an example: You're writing an Ansible role and want to encrypt the spoiler for the movie Aliens.
