Speaker Guide

We look forward to having you present at European Open Source Security Forum 2025, taking place at the Centre for European Policy Studies in Bruxelles, Belgium!

Below are all the logistical details you need to prepare as a speaker:

Questions+Answers (Q+A)

• We encourage you to reserve time for audience Q+A after concluding your presentation, but this must stay within your allocated time and cannot exceed it. If you wish to continue answering questions after your time slot ends, please move the discussion outside the room so we can prepare for the next speaker.
• If an attendee without a microphone asks a question, please repeat it into your microphone before answering to ensure the entire audience can hear it.
• Q+A is only available for full session presentations.

Badge Pick-up

• Before coming onsite, please review the times and location for Registration + Badge Pick-Up.
• Be prepared to have your ID ready for the registration desk if needed.
• Name badges must be worn at all times and cannot be shared with other attendees.
• The event’s Wi-Fi password can be found on the back of your badge.

Confirm Speaking Time Slot and Location

• Please review your presentation time(s) on the schedule.
• Notify the Content Team immediately if there are any conflicts.

Onsite Assistance

• For onsite assistance, please contact the AV tech in your breakout room, an event staff member, or visit our Registration Desk.

Please don’t hesitate to reach out to the Content Team if you have any other questions or concerns.

We’ll see you in Bengaluru soon!

• Speakers must bring their own laptops for presentations. An HDMI cable will be available at the lectern; please bring an adapter if your laptop lacks an HDMI port.
• There will be no hardline at the podium. Speakers must use wifi to access the internet.
• IMPORTANT: Ensure you are presenting in Light Mode. Presentations in Dark Mode may darken and remove blue light to create a warmer, yellowish or orange tone that may not be desired.
• An AV tech will be present during your presentation. Please visit the AV table 10 minutes before your session to review microphone options and get help with connecting your laptop if needed. All speakers should review the Connecting Your Laptop To Present section below.
• Each room will have a screen, projector, and a wired microphone at the podium.

Share Slide Deck

• Please ensure you have uploaded a PDF copy of your slides to Sched.com by Wednesday, 22 October.
• Sessions with PDF copies of presentations attached tend to have better attendance. These PDFs allow attendees to preview your presentation and optionally follow along during your talk. Note that you will present using the PowerPoint version directly from your laptop and not this PDF version.
• Please review these Sched.com instructions, which includes steps and screenshots to upload your presentation PDF.
• If you are not presenting slides, you do not need to complete this step.

Connecting your laptop

• 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.

Presentation Details

All speakers are required to submit a PDF-format version of their final presentation slides ahead of the event to Sched.com. We find that adding the presentations before the event helps to drive interest in attending the session. As a reminder, you will be driving the presentation from your laptop via PowerPoint and this PDF version is only for attendees to review. The deadline for presentations is Wednesday, 22 October.

To upload slides:

• Log in to your speaker profile through Sched.com or via the mobile site
• 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

Branded Powerpoint

We have an optional PowerPoint template for our speakers. Use of this template is not required but we do welcome you to use it for your convenience.

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, 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 and are careful to be inclusive in the words and images used during their presentation.
