It's been a while!

We’re excited to bring Berlin C++ community back together. See you at a post-CppCon evening hosted by think-cell — featuring a live talk, fresh insights from this year's conference, and time to reconnect over drinks, snacks, and good C++ discussion.

Live Talk: To Err is Human — Robust Error Handling in C++26

by Sebastian Theophil, Senior Software Engineer at think-cell

Sebastian will present his CppCon 2025 talk at the meetup. He’ll walk us through the new error handling features in C++26 — including std::expected, std::stacktrace, contracts, and more — and how they can help us write more robust, maintainable code.

Community Discussion & Q&A

After the talk, we’ll be joined by Christian Klöckner, CTO at think-cell, for an open discussion with him and Sebastian about this year’s CppCon, their impressions and insights. If you attended, bring your highlights. If you didn’t, bring your questions. Either way, join us to talk about CppCon 2025 topics and outcomes!

We’d love to hear your thoughts on modern C++, the direction of the language, and what’s shaping engineering work across our community. You’re welcome to submit questions or discussion topics in advance via the RSVP form.

Who’s it for?

This event is open to everyone who cares about C++, whether you're deep in templates or just curious about what’s coming next. No CppCon ticket required, only an interest to connect after this year's conference.

Free to attend. Drinks and pizza provided. Please RSVP so we can plan food and space.

Please RSVP by September 8: https://forms.gle/zvQ3buvEjaLSX6zB7 Space is limited and registration is required.

think-cell is hosting an in-person European Networking Dinner in the US alongside CppCon 2025, and you’re invited.

📍 Location: Aurora Ballroom A, Gaylord Rockies Resort, Aurora, CO, US (outside Denver) 📅 Date: Monday, September 15 🕕 Time: 6:15 PM MDT

This event is for engineers based in Europe, considering relocation to the region, or simply interested in the region’s C++ ecosystem. You do not need to be a registered CppCon attendee to join, yet you need to be able to come to the dinner in person. Event will not be recorded.

Expect relaxed networking, regional tech conversations, and table topics alongside fellow international developers and the think-cell team — including CTO Dr. Christian Klöckner, CppCon speakers Sebastian Theophil and Jonathan Müller, and moderator Timur Doumler.

Make sure to RSVP to attend!

We like to write code, but—despite our best efforts—we make mistakes. Our program will contain bugs. Sometimes, we don’t write what we mean to write, sometimes we don’t understand an aspect of our programming language, and at other times, we lack—or fail to consider—some critical information about our program’s system environment. As a result, our program will not behave correctly. What do we do now?

In this talk, I would like to take you through the entire debugging process, starting with a program that crashes. What do we do next? Which questions do we have to ask? What information do we need? What can we do to find the cause of the crash? Which tools can help us in this quest, and, last but not least, what can we do to make sure this bug never happens again?

Thanks to real-world examples that we have encountered—and debugged—at think-cell over the years, you will learn how to reproduce, locate, understand, and fix even the most difficult bugs.
