In my previous post, I described a technique for putting your Jenkins server configuration under version control. It’s a great way to ensure that your changes are always tracked and that you can recover if/when things get out of whack. However, if it requires you to regularly log onto the Jenkins box and manually run […]
I’ve worked on a variety of continuous integration and continuous delivery projects. We frequently use Jenkins as our platform for driving all build, provisioning, and deployment activities. As part of this, we have a lot of fairly complicated jobs in Jenkins that we are constantly modifying. As a version control pundit, one of my goals […]
Building software in the cloud makes scalability an easy and achievable goal for your organization. As the demand on your Jenkins executor capacity increases, you need to be able to scale your Jenkins footprint to keep up with the demand. This is where the Amazon EC2 Plugin can make a huge impact to […]
This is a continuation of Spring Batch vs Akka. Batching I ran each of these with a commit size of 1 and 10 for a total of 100 records. I was curious what types of improvements would be seen for each batch job and how the increased processing would affect completion time. Additionally, the idea of […]
In this I will talk about Java batch implementations in two different frameworks: Spring Batch and Akka. I looked at both frameworks for a simple ETL program. I ran each of these with a commit size of 1 and of 10. I was curious what types of improvements would be seen for each batch job […]
To summarize the 3 day B-SidesDC conference: Be Afraid. In all seriousness, there are many systems we use daily which are quite vulnerable. The solution is to be vigilant, know what to look for, and understand how to fix it. It is good to know that the industry mindset is migrating towards an “Assume Breach” […]
I’ve written a lot of blogs about how to do certain technical things in Gradle, in this blog I will compare the performance features of Gradle to that of Maven’s. As of Gradle 2.5 and Maven 3.3.3 Gradle supports incremental builds, where Maven does not. Gradle’s incremental builds work off the simple concept of re-building […]
I was reading through some Gradle documentation, and I came across this task CompareGradleBuilds. What this task does is it runs your build on the current version of Gradle, and then runs the build on a different specified version of Gradle, and produces a report that says if the builds are identical or not. I […]
Introduction After giving a talk last week with Sauce Labs about compatibility testing for mobile web apps, I got several questions about simulation using Selenium Webdriver. I had written back in June about compatibility testing using Selenium IDE, but the talk expanded on this concept, allowing tests run in client languages to perform similar actions. […]
In order to set up headless tests on RHEL 6.7, you will need Xvfb, which is a virtual framebuffer that performs the graphical operations without showing anything on the screen. The browser that I chose to use for my headless tests was Firefox. In order to install Xvfb on RHEL use yum: yum install xorg-x11-server-Xvfb […]
