Conference Registration

CppCon 2021 will be held as a hybrid conference.

Online attendees will be able to attend online sessions and some onsite main program sessions live and some onsite main program sessions on a delayed basis. Delayed sessions will feature the presenters in live chat during the delayed, recorded presentation. Onsite-only attendees will be able to attend onsite sessions as well as all the usual onsite activities. Full conference attendees will have access to all online and onsite activities.

On-site attendance is open to fully vaccinated attendees.

For individuals whose organization requires it, a certificate of completion is available for CppCon registration and CppCon Academy classes. To request a certificate contact the CppCon Registrar.

Registration Options

North Denver Metro C++ MeetupGeorgetown Loop Railroad Field Trip:

This year’s field trip takes you up into the rustic mountains of yesteryear, by train! Join us for a ride on the Georgetown Loop Railroad. This year’s field trip is sponsored by the North Denver Metro C++ Meetup.

Conference “Meet the Presenters” Banquet:

Join this year’s presenters (of classes, posters, and sessions) for a banquet on the evening of October 28th. Don’t miss this unique opportunity to dine with conference presenters at a lavish, but informal setting. The food and ambiance will be almost as special as the conversation. This is an add-on for conference registrations that don’t include it.

Online Conference Registration:

Online attendees will have access to all online-only sessions as well as some onsite main program sessions (including all plenary sessions) that will be live-streamed with both online and onsite Q&A. Other onsite main program sessions will be recorded and delay-broadcasted with the presenter live chatting and doing online Q&A.

All of these sessions will be “instantly” available as “rough-cut” recordings for online attendees to view, review, pause, and playback at different speeds. These rough-cut videos will be available to online attendees until the edited versions are uploaded to the CppCon YouTube channel, about a month after the conference ends.

Online attendees will also have access to our virtual venue. This is a fun way to engage with other attendees including presenters and exhibitors. It will have puzzles, games, and amusements in addition to opportunities to create ad hoc video conferencing sessions with other attendees in an online “hallway track.”

Open Content (onsite) Conference Registration:

Evening onsite events (other than the banquet) and all onsite sessions on Friday, October 29th are open to the general public, however you must have a badge, which means that you must provide proof of vaccination in accordance with our vaccination policy.

You may register in advance with Eventbrite, so that a badge is waiting for you, or you may register “at the door” and we’ll create your badge as you wait.
