I have been working on improving the performance of the Role Strategy Plugin as a part of my Google Summer of Code project. Since there was no existing way to measure performance and do benchmarks on Jenkins Plugins, my work for the first phase of the project was to create a framework for running benchmarks in Jenkins plugins with a Jenkins instance available. To make our job...

Two months ago I published an introductory article on the journey of becoming a Jenkins contributor. In that first article, the jenkins.io site was reviewed, learning about the multiple ways in which we can participate and contribute. Then, a first—​basic—​contribution I made to the site repository was described. Now, in this new article we will be exploring more advanced contributions, committing code to the actual Jenkins core. Getting started...

As a software engineer, for many years I have used open source software (frameworks, libraries, tools…​) in the different companies I have worked at. However, I had never been able to engage in an open-source project as a contributor, until now. Since I made my first—​ridiculously simple—​commit into Jenkins, six months ago (in September, 2018), I have been attempting to contribute more to the Jenkins project. However, contributing...

Last week I participated in the Jenkins & Java 10 Online Hackathon. It was my first Jenkins hackathon and I roped in Jonah Graham to do some pair-programming. The hackathon featured JDK Project Jigsaw committers Mandy Chung and Paul Sandoz, as well as Jenkins creator Kohsuke Kawaguchi. It was a great opportunity for me to learn a lot about Jenkins and Java 10. Why Java 10? With the Java 8 EoL data looming, the...

I use macOS day to day, and often struggle to keep my devtools up to date. This isn’t any fault of packaging or tools, more just that I get tired of seeing the beachball: The demands on dev machines grow, developers are now working across a more diverse set of technologies than just a JVM or a single scripting language these days. This keeping up to date is...
