Eclipse Collections is an Open Source Java Collections library with 16+ years in the making. As we start this new year 2021, many feelings come to mind. I started my Open Source journey in 2020 by contributing to Eclipse Collections. In November 2020, I was elected as a committer. I am filled with gratitude and humility for having being given this opportunity, platform, and more importantly, support and kindness from the Eclipse Collections team.
We at Eclipse Collections are thankful to all our contributors and supporters who played an integral role in keeping this Open Source library vibrant and successful. Looking back at 2020, we had an increase in the number of contributors, contributions, Eclipse Collections advocates, and supporters. …

But to me, it is 50 times or more I stayed away from Netflix, Youtube, and the likes to work on an Open Source project. Don’t get me wrong, I have binge-watched a couple of TV shows these past few months. But I can say with certainty that working on an Open Source project is just as fun as binge-watching a full season of Stranger Things.
Working on an Open Source project was a personal goal of mine. My motivations were to explore a different style of learning that allows me to apply new technologies to real projects and pursue a hobby that is both fun and challenging. If you are someone who, like me, aspires to contribute to Open Source projects, I have highlighted some of my personal experiences below. Hopefully, these will help you understand how some of my initial inhibitions became positive experiences. …
