Lightning Talks


News and Updates


  • Slides you plan to present OR a video of your talk
  • Be prepared for a late night testing session to take place on Day 2 or 3.
  • Use the term "Behind Enemy Lines" in the subject of your submission e-mail.

There are no tickets available for lightning talk presenters. Day tickets will be available each day lightning talks are happening.

Please do not submit your presentation without slides or a background graphic. All presentations will be hosted from one laptop so time is not lost dealing with inevitable projector and display issues. In order to be fair to all presenters and cut down on the number of unprepared speakers, a lightning talk will not be scheduled unless the submission includes attached slides, a background graphic or a plan for a substitute graphical element (like the use of lasers).

Discussion: Lightning Talks Discussion

Description: Lightning Talks are 4-minute talks by *you*.

Other: Everyone can register for this until the list is full.

Content: Your talk can be about a program, a system, a technique, some hardware - or about a cool project, or some strange idea. You may also give us an idea about your real talk, announce your workshop or tell us about your booth. Or you could simply ask people to join you for some DOS attack of the next food store, announcing a key signing party, or maybe a *real* party. Whatever it is... be brief. Four minutes is all you get!



All changes to the schedule not made by a coordinator will be reversed.

Note: We will accept registrations until each session is full. If the sessions fill up, we'll start scheduling backup speakers.

Please submit your proposal and slides/background graphic in an e-mail to:

How it Works

  1. Submit your talk in advance. You must submit your slides or background graphic in advance to guarantee a spot on the schedule.
    • Exceptions will be made only for top secret demos and specialized hardware which MUST have a VGA out ready to go. You must bring your own VGA adapter. There will be a hard cut after 4 minutes.
  2. Practice your talk with friends.
  3. Be present in the room 5 minutes before the session starts
  4. Introduce yourself to the moderator and sit in the front row
  5. When called, get on stage
  6. Adjust the microphone.
  7. Introduce yourself
  8. Check your slides or background graphic
    • Say who you are
    • Mention the title again.
  9. If you are using slides, say "next slide" when you want to advance your slide
  10. Speak clearly and loud.
    • Only say the most interesting stuff.
    • Say everything else on your webpage.
  11. When you hear the gong, say goodbye and leave the stage quickly.
  12. Be prepared to meet interested people after the session.
    • Have a flyer, handout and/or business card ready.
    • Get back to them during the congress.

If you are bringing your own display hardware

  • There will be only VGA inputs available
  • If you need to feed in some other type of signal (e.g. from a camera-to show small things (CVBS,S-video), an ultra new laptop which has only HDMI, some weird gaming console that you will crack (YUV), or whatever) bring a device which can really *convert* these signals.
    • Simple passive adapters mostly do not work (e.g. there are adapters from HDMI to DVI and from DVI to VGA, but with the you will *never* be able to convert a HDMI signal into VGA, without a real converter).
    • We will NOT have adapters available
    • You will have 30 seconds to get your display hardware working. If it does not, then we will proceed to the next talk.



  • There is no need to fill the available time.
  • There is no need for any catchy slides, a background graphic is fine.
  • Just be informative, be quick, be smart.
  • Tell people how to get involved and how they can contact you.
  • Add links to the description here in the wiki.
  • Add links to your contact info (ie a dect/phone number, and an email address).

Include the following things in your last slide:

  • Name
  • Contact (DECT, email, fon)
  • Links (project homepage)
  • Place of contact (booth, room, party)
