What I learned during my FreeBSD intership


Hi, my name is Mitchell Horne. I am a computer engineering student at the University of Waterloo, currently in my third year of studies, and fortunate to have been one of the FreeBSD Foundation’s co-op students this past term (January to April). During this time I worked under Ed Maste, in the Foundation’s small Kitchener office, along with another co-op student Arshan Khanifar. My term has now come to an end, and so I’d like to share a little bit about my experience as a newcomer to FreeBSD and open-source development.

I’ll begin with some quick background — and a small admission of guilt. I have been an open-source user for a large part of my life. When I was a teenager I started playing around with Linux, which opened my eyes to the wider world of free software. Other than some small contributions to GNOME, my experience has been mostly as an end user; however, the value of these projects and the open-source philosophy was not lost on me, and is most of what motivated my interest in this position. Before beginning this term I had no personal experience with any of the BSDs, although I knew of their existence and was extremely excited to receive the position. I knew it would be a great opportunity for growth, but I must confess that my naivety about FreeBSD caused me to make the silent assumption that this would be a form of compromise — a stepping stone that would eventually allow me to work on open-source projects that are somehow “greater” or more “legitimate”. After four months spent immersed in this project I have learned how it operates, witnessed its community, and learned about its history. I am happy to admit that I was completely mistaken. Saying it now seems obvious, but FreeBSD is a project with its own distinct uses, goals, and identity. For many there may exist no greater opportunity than to work on FreeBSD full time, and with what I know now I would have a hard time coming up with a project that is more “legitimate”.



What I Liked



In all cases, the work I submitted this term was reviewed by no less than two people before being committed. The feedback and criticism I received was always both constructive and to the point, and it commented on everything from high-level ideas to small style issues. I appreciate having these thorough reviews in place, since I believe it ultimately encourages people to accept only their best work. It is indicative of the high quality that already exists within every aspect of this project, and this commitment to quality is something that should continue to be honored as a core value. As I’ve discovered in some of my previous work terms, it is all too easy cut corners in the name of a deadline or changing priorities, but the fact that FreeBSD doesn’t need to make these types of compromises is a testament to the power of free software.

It’s a small thing, but the quality and completeness of the FreeBSD documentation was hugely helpful throughout my term. Everything you might need to know about utilities, library functions, the kernel, and more can be found in a man page; and the handbook is a great resource as both an introduction to the operating system and a reference. I only wish I had taken some time earlier in the term to explore the different documents more thoroughly, as they cover a wide range of interesting and useful topics. The effort people put into writing and maintaining FreeBSD’s documentation is easy to overlook, but its value cannot be overstated.



What I Learned



Although there was a lot I enjoyed, there were certainly many struggles I faced throughout the term, and lessons to be learned from them. I expect that some of issues I faced may be specific to FreeBSD, while others may be common to
