CppCon 2025 Code of Conduct Transparency Report

Posted on by cppcon

The following summary is intended to help the community understand what kind of Code of Conduct (CoC) incidents we received reports about in the year since the previous conference, and how the CppCon CoC team and organizers responded.

Overview

Again at CppCon 2025, staff and volunteers participated in CoC training prior to the conference.

The Code of Conduct team for CppCon 2025 was Colleen Passard (chair), Gillian Faith, and Jacqueline McCauley. Colleen Passard additionally served as on-site Ombudsperson.

The code of conduct for CppCon 2025 was published here, inclusive of commits up to and including 4c03199ab226e86f31977bad51c2f6c5aa9b5e89.

Summary of reports

Since the CppCon 2024 Transparency Report and during CppCon 2025, there were no CoC incidents reported to the CoC Team.

Attendee Engagement with the CoC Office and Ombuds

The CoC Office and Ombuds served as a resource for attendees throughout the conference, providing confidential support and a space to talk through a variety of personal and professional matters. In addition, some interpersonal frictions were brought forward which the parties did not consider CoC incidents but were constructively addressed with Ombuds assistance to facilitate dialogue or resolution. The community collectively created a respectful, supportive, and welcoming environment for everyone.

Note that the Ombuds role extends beyond, but never replaces, the CoC process. Attendees are fully informed of the option to raise a formal CoC incident report, encouraged to engage in the reporting process when needed, and supported by both the Ombuds and the CoC Team throughout.

CppCon 2025 Wrap-up and CppCon 2026 Dates!

The above photo is from CppCon 2025 by CppCon’s photographer, Jonathan Phillips. Not only do I want to share this brilliant photo, I also want to announce CppCon 2026 dates, September 12-18, 2026, save the dates now!

CppCon 2025 just wrapped up and was an amazing conference. For an early preview of what happened, see Bjarne’s keynote, Daisy’s keynote, Herb’s keynote, Vittorio’s keynote, and Matt’s keynote.

Videos of all our other Main Program sessions will start to be published on our YouTube channel, one a business day, starting in November.

Trip Reports

I’ll update this post as trip reports are published. If you see a CppCon 2025 trip report published or you’d like your trip report to be included, please send us a note. You can see some short reports on LinkedIn and on X.

Thanks

A conference the size of CppCon doesn’t just happen. There are a lot of heroes that work hard to make this happen. You’ll find many of their names on our staff page which lists the organizers, program committee, volunteers, and vendors.

You’d find more names (and faces) on the presenters page for this year’s conference which lists presenters from the Main Program, panels, Poster Program, Open Content sessions, and lightning talks.

As much as all of these people work hard so that we are providing the best that we can in technical content, food, production values, live music, comfortable ambiance, and supportive environment, none of those is the most important part of CppCon.

Returning attendees know that the most important part of CppCon is the opportunity to engage with the attendees (including the presenters), who are tackling some of our most challenging problems, with creative and innovative techniques, using powerful tools provided by C++ and the C++ community.

Above, you’ll see the faces of the most important part of CppCon, the attendees. (I’ve not matched faces to the registration list to verify that no one is missing, but I think most of us are in the photo.)

This year, more than any other, you are all my heroes.

I look forward to seeing you all next year.

We’re in the middle of a fantastic week at CppCon 2025 in Aurora, Colorado! The energy here is incredible. Along with great talks from C++ experts, we’ve had social events (special thanks to think-cell, HRT, and QRT) and panels, including our annual Committee Fireside Chat where attendees had the opportunity to hear directly from C++ standard committee members.

This year’s opening keynote was delivered by the creator of C++ himself, Bjarne Stroustrup. His talk was a deep dive into concept-based Generic Programming, a topic that’s central to the future of the language. For more details, you can visit the original keynote announcement.

For a limited time, we’re giving you exclusive access to the keynote video. This “prerelease” can’t be found directly on our YouTube channel, so we’re providing a direct link here only. Feel free to share this with colleagues and friends and impress them with your insider access! 😉
