Diversity and inclusion in Open Source Software Communities
0 likes220 views
This document discusses diversity and inclusion in open source software communities. It begins by looking at different dimensions of diversity including gender, language, age, location and tenure. It notes the challenges in identifying subpopulations and collaborations within communities. The document then discusses that diversity alone is not enough, and that inclusion, attraction and retention are also important to consider. It provides some examples of people leaving communities due to feeling excluded. The document also discusses codes of conduct that are used in open source projects to promote inclusion.

- 30. code sees no color or gender I have used a fake GitHub handle (my normal GitHub handle is my first name, which is a distinctly female name) so that people would assume I was male interactions are usually positive too, with occasional sexism, but nothing more then one encounters in the rest of life I'm the only female developer, as well as the youngest, which can sometimes be frustrating. Mostly positive. A few collaborators were difficult to collaborate with, hard to discern the real cause. Only one or two were gender related, but one caused me to leave a project.

My current work on userspace graphics enabling may require me to send an occasional quirks kernel patch, but I know I will spend at least a day dreading the potential toxic background radiation of interacting with the kernel community before I send anything. I am no longer a part of the Linux kernel community. Sarah Sharp, http://sarah.thesharps.us/2015/10/05/closing-a- door/

I left because the response I got to the bug was indicative of a severe problem with how dispute resolution and handling of this type of issue works. I've heard a lot of suggestions from individual commentators which seem to boil down to "in the future, email Person X or Person Y" but what I need is the confidence that the system will work not just for me, who knows some of the R Foundation and Core folks in a passing way, but for people who don’t.
