Presenter Information

presenter1This page has information for individuals presenting at CppCon.

Information here will be useful to individuals that are presenting as part of the main program, an Open Content session, a lightning talk, or a poster. Not all content will pertain to all groups.

Thank you for being part of the CppCon program.

If you have any questions, please send them to Robin Kuzman, our Speaker Liaison.


All speakers must register to attend the conference.

Speakers that are speaking as Open Content and/or Lightning Talk (only) presenters do not have their registration waived.

International Presenters

If you are coming to CppCon from another country to give a Main Program presentation, then feel free to mention that your are an invited speaker in the comments section when you fill out your Visa Application Support Form.

Improving the Review Process

Every year the conference receives hundreds of Main Program submissions. The members of the Program Committee spend hundreds of hours reviewing these submission against a tight deadline. This is an admirable accomplishment every year, but the process can be improved and, if you are a Main Program submitter, you can help in either or both of two ways.


We want to motivate reviewers by letting them know that the reviews are valuable to submitters. If you have ever received a review that you feel made a significant difference in the quality of one of your presentations (this year or in past years) of if you just want thank the reviewers for the time they put into drafting reviews (which not all conferences provide to submitters) I’d love to have you write a testimonial and send it to us so we can put in the Reviewers’ Guide.

Example Reviews

We also want to show PC members some examples of what makes a very good and also what makes a very bad review. If you’ve received a review that you think was particularly exemplary of either what to do or what not to do, that you don’t mind sharing (we won’t name any names), please send it to us. Particularly valuable would be an exemplary review that was negative, but still constructive and therefore valuable.

After you’ve been notified that your account has been created, please upload a photo of yourself to the account and proofread/update your bio. Whether or not your photo and bio are completed is one of the single biggest drivers of session attendance.

Meet the Speakers Banquet

All main program speakers (those that submitted and were accepted by the Program Committee) and poster presenters are invited to be our guests at the Meet the Speakers Banquet; however, you must register for it and we will assign your seating.


Please let people know that you are speaking! You are the attraction for this year’s CppCon, so let people know on Twitter (#CppCon), Facebook, LinkedIn, Slack, or where ever is appropriate for you.

Connecting with others

If you want to engage with other CppCon attendees, including other presenters, please join CppCon Slack workspace. If you are registered for the conference or are a speaker, you should have received an invitation to this workspace. If you have not, please contact

Robin Kuzman, our Speaker Liaison.

In addition to joining the #sig_speakers_corner channel on the CppCon Slack workspace, consider joining the CppLang Slack workspace #speakerscorner channel by first using the auto-invite page for the CppLang workspace. This is a good way of asking questions of, and getting advice from experienced presenters at other C++ conferences.

Please engage with other attendees. Getting to know your audience is one of the best techniques of presenting.


Please have a title slide with your talk title and your name as you want them to appear on the recording of your session. Because talk titles do change, Bash Films, who does our physical session recordings, use these slide as definitive for the names of both you and your talk. For our virtual session recordings, this is less of a concern but consistency is key in maintaining a professional conference.


Speakers don’t want to be interrupted by an audience member’s phone going off in their session, but it is surprising how often speakers forget to turn off their phone.
If you have an Apple Watch, you may not know about theater mode. Theater mode prevents your watch face from lighting up while presenting which is one less distraction for your in-room and video audience.


If possible, give your talk before a live technical audience. Do it at work and/or with a local user group. You’ll be surprised at what you learn about how long it takes, what you find yourself wishing you’d included, and what questions you get. Pay attention to these issues, learn from them, and incorporate them into your talk. It will improve every time you give it, try to give it as many times as you can arrange an audience.

Crowd Control

If it looks like your room is filling up, please help attendees find a seat. It is much more difficult to spot empty seats from the back of the room than from the front. It is also less intimidating to walk to the front of the room if the speaker has invited you down to fill an empty seat.

If you find that your session is filling and people are standing at the sides or in the back, please ask that attendees “move to the middle” to open up space on the aisles.


Please be prepared for questions. It is your choice to take them at the end or as you go. Expect to allow five to ten minutes in a one hour talk for questions.

How and why to repeat questions

There are two important reasons to repeat questions. One is that, even if you can hear the question, others may not. They may be seated behind the individual asking the question, so the questioner is facing away from them. Even if everyone in the room can hear the question, it may not be picked up well on the recording. You have a microphone; your version of the question will be clear.

So, if the questioner has a microphone, you don’t need to repeat the question, right? Wrong, because there is another reason to repeat the question (in your own words) and that is to let the questioner and the audience know what you thought was asked. Sometimes it isn’t clear what the questioner is asking. Time spent clarifying a point that was already clear is wasted time. Putting the question in your own words allows the questioner to say, “No, what I’m asking is…”

Not only does it work better to put the question in your own words, it may be smoother to just incorporate the question into the answer. “Yes, we could use a lambda expression here.” This works even if it is a comment rather than a question. “Correct, it would be wrong to use ‘unsigned’ in this case.”

Ending Your Presentation

It isn’t uncommon for content to take longer to deliver than you expect. This is part of the reason that we urge you to practice before a live technical audience. We aren’t so tightly scheduled that (with one important exception–see Half-Hour Sessions) you can’t go over by a minute or two. But do not go beyond that.

If you find that questions are taking you beyond your allotted time, you may cut them off by saying that you’ll continue to take questions in the hallway or by giving a way of contacting you.

You may feel that, since you were speaking before the lunch or dinner break, that you are free to run long. That is not the case. The audience, the volunteers, and the camera operators are all within their rights to expect you to end when you agreed to end. To not do so is rude and not acceptable.

The volunteers have been instructed to cut you off, but they really don’t want to do that. It is awkward for everyone. Practice your session, watch your time, skip the digressions if necessary, and end on time.

Half-Hour Sessions

If you are scheduled to deliver a half-hour session, you help is needed to make the program run smoothly.

First Half

If you are giving the first half-hour, arrive at your session extra early because not only will you need to get your AV setup and checked, the following presenter will need to be setup and checked as well. Please let the following speaker get set up and checked before you, so you’ll be setup and ready to go for your talk.

It is very important that you start on time, so that you be able to finish on time. Finishing on time means finishing with questions as well. You need to be off-mic and unplugged at the end of your half-hour so the following speaker will have their full session to present. If you want to offer to take more questions in the hallway, please say that you’ll be available after the next speaker is finished, not during that speaker’s session.

If you are scheduled for the first of a pair of half-hour talks, you cannot go over our time. You must stop when your time is up. There are no exception to this, even if your sessions started late through no fault of your own.

Second Half

If you are giving the second half-hour, arrive early before the session before yours starts. You need to be checked out on AV before the first presenter(s) setup for their talk. Since you need to allow at least ten minutes for the other speaker to be setup, you need to arrive in time so that you can be finished being setup (including necessary troubleshooting) at least forty-five minutes before your session is scheduled to begin.

It is understandable that right before speaking you might be too nervous to sit quietly through their talk (although that might help calm your nerves). If you can’t avoid pacing, please slip out of the session, but not far away. You’ll need to be available right after the previous speaker finishes to get set up and going.


Better safe than sorry: Your laptop may break or go missing. Consider:

  • Have copy of your slides on a USB stick.
  • Mail yourself a copy of the slides.
  • Put a copy on Google drive/Dropbox/iCloud.

Advice from AV Factory

We no longer work with the Meydenbauer’s in-house AV company, but their advice is still useful:

As for speaker information, we can accommodate any format, resolution, etc, from 1080p and below.  16:9 format is best for the screen sizes in the plenary and breakout rooms.  All rooms will have VGA and HDMI capabilities located at the podium, as well as a computer audio patch.  We do carry some video adapters but cannot guarantee we can accommodate everyone at the same time.  So we do recommend that presenters bring their own video display adapters if they have one.  But we will cover what we can.

Because we have various room and screen sizes, the safest information we can give is to use font size between 18-24 for all text.  This will assure everyone will see fine.  For the keynote room, I suggest sticking to closer to 22-24.  Also keep in mind contrasts.  Make sure text contrasts well with the background color of the slide.”
