A list of C++ meetup dates does not tell you which session will answer your current question. The public prerecordings highlighted in the November 2026 user group announcement offer a useful starting point for choosing by learning goal.

Selected talks are available to attend for free, but a prerecording could sound like either watching a finished video or joining a recording session. Understanding the format first makes it easier to choose between topics such as return-value optimization and reflection.

Public prerecordings let you attend talks before the conference

These are recording sessions with an audience for the online-only conference track. Sessions are listed for November 3 and November 10, 2026, with attendance links in the organizer’s prerecording announcement.

The November 3 event page identifies an online event, with the connection link visible to attendees. Talks are recorded as delivered; questions follow in the lounge at the relevant talk table. That gives the session a different interaction pattern from watching a published video.

The main Meeting C++ 2026 conference runs in Berlin and online on November 26–28, 2026, with tickets offered separately. Free attendance at selected prerecordings does not mean the entire conference is free.

Choose NRVO or reflection by the question you want answered

The prerecording schedule provides two different mixes of topics. These are the dates listed by the organizer; check the attendance pages for start times.

Scheduled recording date	Talk topics, summarized	Possible learning goal
November 3, 2026	Cortex-M startup, return-value optimization, a tiny Pomodoro timer	Explore embedded development or object construction
November 10, 2026	Reflection-based scripting, Neovim, numerical computing with complex and related numbers	Revisit design techniques, tooling, or performance

For questions about copying returned objects, consider Ivan Khodar’s return-value optimization session. Its abstract promises examples and a look inside Clang.

The relevant background is NRVO: under specified conditions, a named local object can be constructed directly as the function result. The C++ working draft’s copy/move elision rules permit this for a same-type, non-volatile object with automatic storage duration returned by name, excluding parameters. NRVO is permitted, not required. Thus, return result; alone establishes neither that a copy happens nor that it is eliminated. Separating language permission from compiler behavior gives you a concrete question to bring to the talk.

For design exploration, Koen Samyn’s game-engine reflection session describes lifting script bytecode into template structures using C++26 static reflection so the compiler can optimize them. This is the approach proposed in the abstract, not a performance guarantee for arbitrary game engines.

Join from Japan using the recording event’s date and access page

Once you choose a topic, return to the attendance page for that recording date. The conference slot shown on the NRVO talk page and its November 3 prerecording are separate appointments. Keep the event name alongside its date when adding it to your calendar.

If joining from Japan, compare the displayed time zone with the date and time entered in your calendar. The November 3 program is also marked as tentative, so revisit that attendance page for connection details and session arrangements.

For other topics, the November user group listing includes test-framework comparisons and an introduction to contract assertions. Choose the question first, then match the attendance format and time. That turns an event calendar into a learning plan tied to implementation or design decisions.
