In collaboration with the National Center for Women in Technology (NCWIT), the Linux Foundation has created an online course designed to teach the viewer about inclusion, diversity, and unconscious bias. We highly recommend all of our speakers watch the course to learn tips/tools to use when speaking to encourage inclusivity in presentations and messaging.

Please read and abide by our Code of Conduct, which is strictly enforced. We ask that speakers especially review this code of conduct and are careful to be inclusive in the words and images used during their presentations.

If you have any other questions regarding platforms, speakers, or schedules, please contact us at cfp@linuxfoundation.org.
