I'm just getting up to speed on AWS, and so I'm learning my way around the CLI. It's nice and easy to do lots of things from the CLI, like querying, creating and destroying instances and images. There are lots of fiddly bits involved in parsing output so it can be used by a script or something, though, so here are some notes.
Obviously you need the AWS CLI. It's an easy install using pip. Go here to find documentation and other install methods.

| class << self | |
| attr_accessor :opposite_operations | |
| end | |
| def self.define_opposite_operations(name, name_of_opposite) | |
| @opposite_operations ||= {} | |
| @opposite_operations[name] = name_of_opposite | |
| @opposite_operations[name_of_opposite] = name | |

Let's have some command-line fun with curl, [jq][1], and the [new GitHub Search API][2].
Today we're looking for:
I spent a lot of time trying to find a pretty optimal (for me) setup for Clojure… at the same time I was trying to dive in and learn it. This is never optimal; you shouldn't be fighting the environment while trying to learn something.
I feel like I went through a lot of pain searching Google, StackOverflow, blogs, and other sites for random tidbits of information and instructions.
This is a comprehensive "what I learned and what I ended up doing" that will hopefully be of use to others and act as a journal for myself if I ever have to do it again. I want to be very step-by-step and explain what's happening (and why) at each step.
