Deadline to upload slides: Tuesday, 9 September

All speakers are required to submit their final presentation slides ahead of the event. In addition to providing a hard copy for accessibility purposes, we find that adding the presentations before the event helps to drive interest in attending the session.

To upload slides, follow these instructions (guide with screenshots):

• Log into your speaker profile through Sched.com
• On the top of the page, click “Manage and Promote Your Session”
• Click “Add Presentation”
• Click in the “Select a File” box and add the PDF document (note: there is a 50MB size limit)
• Click “Upload” and your slides will automatically be saved

A presentation template is available to download. Use of the template is optional.

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 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. Our code of conduct 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 platform, speaker, or schedule-related questions, please contact Shannon Jessee at sjessee@linuxfoundation.org.
