Quick MySQL Box Using Vagrant and Ansible

Update July 19, 2014:

The default MySQL Server package in the CentOS repo is ridiculously old (5.1 - MyIASM is the default storage engine). If you need the newest version of MySQL, there is an RPM for the Oracle YUM Repo which will provide you the latest packages. I can't provide you that here because you have to accept Oracles Terms of . . .

Failing at Microservices.

Please avoid our mistakes!

Microservices are the new fad in software architecture, and while I think they are generally the correct philosophy to take with service design and composition, the pattern can certainly lead you quickly into trouble. If you don't know what Microservices are, I recommend reading the article written by Jame Lewis and Martin Fowler on the . . .

Deploying Triggers in MarkLogic Roxy

Let me save you three hours of annoyance.

Over the last two weeks, I've been building a RESTful backend in MarkLogic (ML) using the Roxy framework. If you're unfamiliar with MarkLogic, it's a pretty excellent XML database, search engine, and application host (where the app is written in xQuery). That's an extraordinary complement because I generally prefer JSON or . . .

Passing State via Services

AngularJS - Communicating Between Controllers - Part 4

This is the 4th and final discussion of Communicating Between Controllers in AngularJS. In the previous three posts, I discussed using nested state, PubSub, and the router as mediums for passing state between controllers. In this post, I will discuss perhaps the most obvious (but least thought of in Angular); using an independent service . . .

Passing State via Routes

AngularJS - Communicating Between Controllers - Part 3

In the previous two articles, we discussed passing state using scope variables and Angular's PubSub mechanism.

Another, often overlooked mechanism, is the URL.

I'm going to assume you already understand the concept of URL routing in an client side application. If you don't, I suggest you do some precursor research on the web . . .

PubSub Controller Communication

AngularJS - Communicating Between Controllers - Part 2

In the last post, we discussed communicating between controllers using a controller's scope. This mechanism, however, is limited only to parent-child relationships between controllers (i.e. one controller is nested within another).

A more general way of communicating between controllers is to use Angular's PubSub mechanism.

PubSub in . . .

Parent/Child Controller Communication

AngularJS - Communicating Between Controllers - Part 1

I've been teaching AngularJS to a couple of friends lately and they almost universally ask the same question:

How do I pass information (state) between controllers?

It's a great question and it's often not obvious to new Angular users. The answer is a lot more complex than one might think (but the implementation is simple).
