In this post I would like to show an example of how to use JUnit Rule to make testing easier.
From software developer Curtis Lassam (who writes about comics and code) comes a comic series called Cube Drone. This is Cube Drone #4: Poom.
When developers think about unit testing web applications, we often focus on server-side code. But with the right tools and programming techniques, we can achieve the same rigorous test quality in our client code that we expect from our server code.
I use Python’s 'type' function for dynamically creating custom Maya nodes based on specifications, such as input and output attributes. I really love the 'type' function, so I thought I’d post another cool use of it.
At Codeship we always look into new ways how we can leverage Codeship to automate our workflows. A while ago we started Continuous Deployment of our DNS records.
Fragmented approaches to APM are being promoted as solutions to support the DevOps ideal of continuous integration and delivery, but the stark lack of integrated tools in these APM arsenals isn’t likely to make communication and collaboration between dev and ops any easier or more efficient.
This article will teach you how you can setup an environment to develop in an event-driven fashion using Spring Boot and the Reactor framework.
JSF is not what we often think it is. It's also a framework that can be somewhat tricky to debug, especially when first encountered. Let's go over on why that is and provide some JSF debugging techniques.
There are a lot of exciting tools in the infrastructure and visualization space that have emerged in the last couple of years. Ansible and Docker are probably two of the most exciting ones in my opinion. This is my take on where Docker and Ansible is and isn't useful.
Systematic reuse initiatives don’t have to be big-bang events preceded by a lot of noise. It can be done quietly – project by project with a resolute focus on getting targeted wins
In my last post, I delivered on a reusable, file archival schedulable job. I promised to next look at doing something similar for file cleanup.
Debugging methods can be categorized as active and passive. Active debuggers reduce the code size to be visited for bug hunting, while passive debuggers display any information you need. We introduce some new active methods. We also show how the usage of active debuggers helps you to debug more efficiently.
You might have noticed that we have been doing a lot of work on the operational side of things. To make sure that we give you as good a story as possible with regards to the care & feeding of RavenDB. This post is about your applications and systems, and how you are going to react when !@)(*#!@(* happens.
If you fail to articulate to the clients what these numbers will mean to them in terms of cost, you wont ever get them accept the reality of internet and the universe. More often than not you will realize how business will realize that there are services they can live without.
DevOps and full-stack have been popular topics in our industry for a number of years now. Unfortunately, they don’t always mean the same thing to every organization or even individuals within an organization.
I have talked about human filters and my plan for digital curation. These items are the fruits of those ideas, the items I deemed worthy from my daily reading. These items are a combination of tech business news, development news and programming tools and techniques.
When setting out to use Git there are lots of basic tutorials, but none that approach it from a zero-to-hero in a team environment. In this blog series I am going to trying to set out to change all that by walking you through the steps from working in a non-Git source control environment to using DVCS with other people.
Here’s a familiar scene: You’ve finished developing your application or a neat new feature and you’ve created the right system logs for new capabilities. You’re confident that if something breaks, you can easily spot the errors and overcome them efficiently.
We all have “enjoyed” working with some software that was purchased because “You can’t get fired because you bought…”. This software is known for being the industry leader. Not because it is easy to use, easy to integrate, easy to scale, easy to do anything with,… It often is quite the opposite.
Unit testing is a set of skills, that rarely appears on a resume. When I saw a resume with unit testing on it, it rose up to the top of the interview queue. I understood the person who put it there understand what it means to the business.
Here is how you can automate deployment for WebLogic server using the command line.
Hystrix is a Java library aimed towards making integration points less susceptible to failures and mitigating the impact a failure might have on your application.
Do you use anemic models? i.e. having business classes like “User” without any methods but just properties instead? Do you want to do better but do not know how?
In the forthcoming articles we consider traditional and state of the art debuggers, introduce some new methods make debugging easier and describe and efficient process of bug hunting. In this first article we shortly outlined the main methods of traditional debugging, and explain their advantages and disadvantages.
Monitoring is a big part of DevOps, but what’s the best way to get started? Infrastructure monitoring? Application monitoring? What should you monitor? Where should that data go? How can you turn data into information and monitoring into alerts? What about alert fatigue and humane monitoring?
