Static:Lightning Talks

Lightning Talks are short lectures (almost) any congress participant may give!

Bring your infectious enthusiasm to an audience with a short attention span! Discuss a program, system or technique! Pitch your projects and ideas or try to rally a crew of people to your party or assembly! Whatever you bring, make it quick! To get an idea what Lightning Talks are about and how they work, look at the lightning talks sessions from 35C3.


The Lightning Talks are full! Registration is closed.

If you have any questions, please send a mail to the Lightning Talk team. We speak English and German.


Please see for a schedule in various formats like iCal, JSON, XML. At camp there will be an single XL session on Day 2 starting at 12:00 and ending at 15:00 taking place in Tent Meitner.

In the unlikely case that something bad happens to the wiki or this page, follow @C3_LightningTLK on twitter for announcements.

If you have submitted a talk and it does not appear on the schedule, possible reasons might be:

  • You have not yet submitted (at least preliminary) slides. No slides - no timeslot - no scheduled talk.
  • Your talk was accepted but you have not yet confirmed your attendance. CYM.
  • The lightning talk team was lazy. We try to update the schedule at least once a day and in the days directly before the talks more often. Please have some patience.
  • If none of the above apply and you think there is some error on our side, please contact us by mail.

Day 2 - 2019-08-22

How long are the Lightning Talks?
So we can maximize the number of cool talks and opportunities, talks are no longer than 5 minutes.
I've never given a talk before, I don't think I can do it!
Yes you can! Many LT presenters have never spoken in front of a huge audience. This format is great for first-time speakers to get their awesome ideas out and gain comfort speaking in a safe and friendly space.
My lecture didn't get accepted, I need at least OVER 5 MINUTES to give this talk!
The sad fact is that most lectures designed to be given in over 30 minutes by speakers accustomed to taking more than 45 minutes cannot be successfully cut down to a coherent 5 minute talk. We suggest focusing on one particular element of your talk that you can give in 5 minutes or less.
What presentation formats are accepted?
We accept talks as PDF files only. There is basically no other way to efficiently switch between talks and review A LOT of slide sets in advance than having a common format for all slide sets. Please set up your presentation size to be viewed in 1920x1080 (aka widescreen aka 16:9) to make the video angels happy. If your presentation contains large images, please reduce image size to 1920x1080 or page transitions might take too long which will disturb your flow.
Yes. But. My slides just need those animated transitions.
Please try to live without them. Less is more. People come for you and your ideas.
But I need to connect my laptop to do this awesome demo!
Bear in mind, you have 5 minutes to get set up, give your talk, and get off the stage. If you can give a three minute awesome demo, go for it! Specify that you need to do this in your registration. Expect to receive a slot at the end of the session.
