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 . . .
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.
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 . . .
Introducing Nagios-Dropwizard
Super simple Nagios checks via Dropwizard Tasks.
On a project I'm currently working on, I had a need to create a framework to expose Nagios health checks within a Dropwizard service. You can find the framework and a check_url.py Nagios check script on Github here: Nagios-Dropwizard.
Why not use Dropwizard Health Checks?
The health check facility on Dropwizard . . .
Pipelines in Golang
There's a really good article on the Golang blog about Go Concurrency: Pipelines and cancellation.
I came across the article while learning Go, more specifically, I was building an image processing pipeline for my home security cameras. The examples are great, however, I felt they could be improved a little.
First, it . . .
