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 am currently working on a project in which we are helping a company transition to using the agile software development methodology. As part of this transition to agile we set up Jira, Confluence, and Zephyr — Jira is used for managing work (epics, user stories, requirements, and test cases), Confluence is a wiki used for managing […]
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 […]
Intro On the current engagement we are using gradle to automate the build process. Gradle can lend itself to scripting through groovy. Anything groovy can do gradle can do. I’m interested in more than just building the application automatically. When it comes to Continuous Integration (CI) we often need to do more than just build […]
Dear Loyal Readers, I’ve been using bind in AWS for a while now. Initially route53 created publicly available DNS entries, but recently, AWS added the private/vpc-aware Route 53. This makes our security team happy! Sadly, the record propagation delay was causing us problems (long delays) in our ability to quickly spin up new instances. We might have been able to live […]
The software development IDE, JetBrains PhpStorm, is a versatile tool to incorporate into a DevOps pipeline. One useful method of expanding upon its native features is to add the SonarQube plugin to provide source code analysis. Step-by-step documentation is scattered or insufficient, so I have compiled an explanation of the process, with accompanying screenshots. This does […]
