Schedule, Timing & Speaker Profiles

The schedule will be announced Thursday, April 13,, and will be posted on our website using sched.com.

If you have a conflict with the timing of your talk or find that it conflicts with the content of another talk; or are having problems uploading your bio and photo to sched.com, please contact cfp@linuxfoundation.org.

AV Details & Requirements

Please note the following technical requirements:

  • All speakers must supply their own computers and adapters to use during their talk.
  • Presentation slides should be formatted in 16:9. 
  • The room will include a screen, projector, and (2) microphones; panelists will each receive their own microphones.
  • If you require any additional AV, please email cfp@linuxfoundation.org with those needs by Tuesday, June 13. The Linux Foundation will make every effort to accommodate additional AV needs; however, final approval for additional AV requests will be made on a case-by-case basis.

Presentation Template & Slide Upload

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.

Can’t Speak in Person?

We acknowledge that there may be circumstances beyond your control that may prevent you from speaking in person. While we are recording all conference sessions at this year’s event, and live streaming talks delivered onsite, we will not be using a virtual platform. All sessions that will be delivered virtually will be published prior to the event to registered attendees as pre-event content.

Due to our on-site set-up, we do not have the capabilities for dual presentations where speakers are both onsite and virtual. Speakers need to either be in person or send in a virtual recording.

The Speaker Guide contains further details on this below and kindly note that all video submissions must be received by Tuesday, May 30. Please add your recording directly into the Google folder (please email cfp@linuxfoundation.org to confirm we received your file) or share your file with cfp@linuxfoundation.org.

If you are currently planning to speak in person, but circumstances change after the May 30 video submission deadline, we will, unfortunately, need to cancel your talk and replace it with a waitlisted session.

VIRTUAL: Pre-recording Information

Speakers that are unable to attend in person, will need to pre-record and submit their talk no later than May 30, 2023.

  • Some suggested tools to use for recording are Quicktime, Google Hangouts, Zoom, a screen recorder, or something similar. The recording should show your slides/screen as well as you presenting using a picture-in-picture style format.
  • The platform accepts MP4 or MOV (under 5gb), dimensions: 1280 x 720 (720p), 1920 x 1080 (1080p).
  • The recording must be no more than 40 minutes (allotted session time).
  • If you need assistance with your pre-recorded talk, or have any questions, please contact us at cfp@linuxfoundation.org for additional information.
  • Ensure you have stable internet access.  Hardwired connection is preferable for your recording.  If a hardwired connection is not available, turn devices off that will affect your connectivity during your presentation, and make sure that anyone in the house is not on devices and/or consuming bandwidth.

Helpful Zoom Documents and How-to’s:

We have multiple options for uploading your pre-recorded presentation:

VIRTUAL: Technical Tips

  • Audio – as counterintuitive as it may sound, the single most important factor in a good video, is the audio quality. 
  • Eliminate ambient noise – close the doors and windows. You’d be surprised how much environmental noise gets picked up.
  • Lighting – do not put lights overhead and don’t put any lights or windows behind you as they will alter the light levels in your videos and create shadows. Do use a ring light or other lighting source placed in front of you. Natural lighting is best.
  • Background – don’t be afraid to show your natural environment – bookcases, plants, paintings – as long as they are not too distracting.
  • Framing – place yourself slightly off-center to the left or right rather than directly in the middle of the frame.
  • Camera Height – the lens should either be directly level or pointing ever so slightly downwards towards your face.
  • Stand – we recommend you stand during your presentation to help project your voice and improve your posture. However, if you’re more comfortable sitting, then please do so.
  • Timer – have a clock to keep track of the time you have remaining.

VIRTUAL: Lighting, Webcam and Microphone Best Practices

Best Practices for Lighting

  • For best results, use natural light and supplement with additional light as needed.
  • Keep natural light in front of you to avoid shadows. A bright window behind you can make you appear as a dark silhouette. 
  • Interior rooms with no natural light source may require additional targeted lighting, such as a ring light, to brighten the speaker’s face.

Best Practices for Webcams

  • To ensure the speaker is looking directly at the audience, place the webcam at eye level.
  • Avoid distracting backgrounds by checking the surroundings behind you to make sure there are no distracting colors or movements.
  • Presenters should use chairs that are adjustable for height but do not swivel. Swiveling on camera creates a poor attendee experience and can be distracting.

Best Practices for Microphones

  • Use external microphones whenever available, as microphones built into computers and cameras often have lower quality. 
  • An external microphone allows the speaker to place it in the optimal location for sound.
  • Place the microphone close to the speaker’s mouth, but not in the camera view.
  • Test audio levels in advance.
  • Manage noise by turning off fans, phones, or speakers and keep ambient noise to a minimum. 
  • Do not touch the microphone while unmuted.

Dress Code

  • There is no dress code for presentations, and we encourage you to be comfortable. That said, you must be aware that the Code of Conduct applies to this space, both in terms of what you show on camera and what you say. We ask that you be tasteful and considerate in choosing your clothing and surroundings. Keep in mind that we are a global community. Please refrain from wearing shirts with global brand logos that are not your own. Solid colors (not white) also work best instead of prints. 

Inclusive Speaker Orientation Online Course

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. 

Along with the online course, we suggest that speakers also refer to the Inclusive Language Initiative’s language recommendation list, which provides guidance on substituting hurtful and exclusive language in the field of information technology.

Code of Conduct

Please review our code of conduct which all participants must follow. It’s strictly enforced and we ask speakers to prioritize inclusivity and appropriate language and imagery in their presentations.
