Please note the following technical requirements:

• All speakers must bring their own computer and adapters for their talk.
• Presentation slides should be formatted in a 16:9 aspect ratio.  
• The room will include a screen, projector, and (1) microphone for each speaker.
• Need extra AV? Email Jennifer Crowley by 15 September. The Linux Foundation will make every effort to accommodate other AV needs; however, final approval for AV requests will be made on a case-by-case basis.

All speakers are required to upload their final presentation slides by 5 October. In addition to providing a hard copy for accessibility, we find that adding the presentations before the event helps drive interest in attending the session.

Please note that your presentation slides should be formatted in 16:9 and submitted as a PDF.

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

An optional PowerPoint template is available to download here. Use of the template is optional.

If you plan to use speaker notes, please follow the steps below to ensure your laptop is set up correctly. This will allow you to view your notes while the audience sees only your slides.

Use “Extended Display” mode (not Mirrored)

In collaboration with the National Center for Women in Technology (NCWIT), the Linux Foundation has created an online course to teach the viewer about inclusion, accessibility, 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 can be found here. 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 questions, please contact Jennifer Crowley at [email protected].
