HOWTO: Installing Vault On AWS Linux

This is quick howto for installing vault on AWS Linux, mostly to remind myself. At the end of this tutorial, you'll have a working vault server, using s3 for the backend, self signed certificates for tls, and supervisord to ensure that the vault server is always running, and starts on reboot.

Setting up S3

First things first, let's set up an s3 bucket to use as the storage backend for our s3 instance.

From the AWS Mangement Console, go to the S3 console.
Click on the Create Bucket button

This is part of a set of visualisation that try to improve the Barclay's bike distribution in London. Visualizing the map of the London Tube is the first step to understand any correlation with bikes usage.

Aim

The technical aim I tried to achieve, is a very simple codebase that enables interaction (such as zooming) for later data analysis.

Inspiration

I have been using RandomETC's idea. However, in order to support scaling and to have a more structured code-base, most of the code has been re-written.

Creating a new Jenkins Server

First step, make sure java -version reports 1.6 or higher. If the command fails or the version isn't high enough, download the latest version of Java JDK from Oracle (http://www.oracle.com/technetwork/java/javase/downloads/index.html) (jdk-7u25-linux-x64.tar.gz at the time of writing) - a quick uname -m will let you know if you need the 32 or 64bit version. Installation instructions are available here (http://docs.oracle.com/javase/7/docs/webnotes/install/linux/linux-jdk.html#install-64).

My preference is to extract these to /usr/local and then ln -s /usr/local/jdk1.7.0_25 /usr/local/jdk.

Add /usr/local/jdk/bin to your $PATH.

Download the latest Jenkins WAR (1.519 currently) file from http://mirrors.jenkins-ci.org/war/latest/.

Awesome PHP Libraries

A list of amazingly awesome PHP libraries that you should be using:

Composer/Packagist - A package and dependency manager.
Symfony2 - A framework comprised of individual components.
Zend Framework 2 - Another framework comprised of individual components.
Symfony2 Components - The components that make Symfony2.
Aura Components - A package of PHP 5.4 components.
Illuminate Components - The components that make the upcoming Laravel 4 framework.

PSR-0 Final Proposal (PHP Standards Working Group)

The following describes the mandatory requirements that must be adhered to for autoloader interoperability.

Mandatory:

A fully-qualified namespace and class must have the following structure \ <Vendor Name> \ (<Namespace>)* \ <Class Name>
Each namespace must have a top-level namespace ("Vendor Name").
Each namespace can have as many sub-namespaces as it wishes.
Each namespace separator is converted to a DIRECTORY_SEPARATOR when loading from the file system.
Each "_" character in the CLASS NAME is converted to a DIRECTORY_SEPARATOR. The "_" character has no special meaning in the namespace.
