C++ Podcasts & Conference Talks (week 47, 2025)

Hi r/cpp!

As part of [Tech Talks Weekly](https://www.techtalksweekly.io/), I'll be posting here every week with all the latest C++ conference talks and podcasts. To build this list, I'm following over [100 software engineering conferences](https://www.techtalksweekly.io/i/170091550/conferences) and even more podcasts. This means you no longer need to scroll through messy YT subscriptions or RSS feeds!

In addition, I'll periodically post compilations, for example a list of the most-watched C++ talks of 2025.

The following list includes all the C++ talks and podcasts published in the past 7 days (2025-11-13 - 2025-11-20).

Let's get started!

# Podcasts

# CppCon 2025

1. [**"Concept-based Generic Programming - Bjarne Stroustrup - CppCon 2025"**](https://youtube.com/watch?v=VMGB75hsDQo&utm_source=techtalksweekly&utm_medium=email) ⸱ **+15k views** ⸱ 14 Nov 2025 ⸱ 01h 23m 29s tldw: You'll learn about concept-based generic programming with practical examples, including a tiny type system that prevents narrowing and enforces range checks and walks through design rationale, relations to OOP, and C++26 static reflection, worth watching if you write generic C++.
2. [**"Implement the C++ Standard Library: Design, Optimisations, Testing while Implementing Libc++"**](https://youtube.com/watch?v=iw8hqKftP4I&utm_source=techtalksweekly&utm_medium=email) ⸱ **+3k views** ⸱ 18 Nov 2025 ⸱ 01h 01m 07s tldw: A practical tour of libc++ showing space packing tricks, wait and iterator optimisations, and rigorous testing techniques that’s worth watching if you care about squeezing performance and correctness out of C++ standard library code.
3. [**"The Evolution of std::optional - From Boost to C++26 - Steve Downey - CppCon 2025"**](https://youtube.com/watch?v=fTbTF0MUsPA&utm_source=techtalksweekly&utm_medium=email) ⸱ **+2k views** ⸱ 17 Nov 2025 ⸱ 00h 59m 49s tldw: See how std::optional evolved from Boost to C++26 to learn why optional references are so tricky, what landed (range support and optional), and how those design tradeoffs reshape sum types, lifetime safety, and everyday C++ code; watch this talk.
4. [**"Could C++ Developers Handle an ABI Break Today? - Luis Caro Campos - CppCon 2025"**](https://youtube.com/watch?v=VbSKnvldtbs&utm_source=techtalksweekly&utm_medium=email) ⸱ **+1k views** ⸱ 19 Nov 2025 ⸱ 01h 03m 19s tldw: This talk asks whether C++ developers could handle an ABI break today, examines libstdc++'s history, common library ABI pratfalls, and how tools like Conan and vcpkg mitigate risk, and argues the pain might be less than we fear so give it a watch.

# Meeting C++ 2025

1. [**"Casts in C++: To lie... and hopefully - to lie usefully - Patrice Roy - Meeting C++ 2025"**](https://youtube.com/watch?v=spxCeWT-GrA&utm_source=techtalksweekly&utm_medium=email) ⸱ **+400 views** ⸱ 15 Nov 2025 ⸱ 01h 11m 37s tldw: This talk explains why we sometimes lie to the compiler, what each cast actually does, when writing your own makes sense, and practical tips to avoid surprises, so watch it.
2. [**"Does my C++ Object Model Work with a GPU and Can I Make It Safe - Erik Tomusk - Meeting C++ 2025"**](https://youtube.com/watch?v=OSGDH_oK2s0&utm_source=techtalksweekly&utm_medium=email) ⸱ **+300 views** ⸱ 13 Nov 2025 ⸱ 01h 01m 25s tldw: This talk answers whether C++'s object model can work with GPUs and be made safe, using code examples, accelerator API design, and hardware details that matter for real time and safety critical systems.
3. [**"Designing an SPSC Lock free queue - Quasar Chunawala - Meeting C++ 2025"**](https://youtube.com/watch?v=mus6djSJLLc&utm_source=techtalksweekly&utm_medium=email) ⸱ **+200 views** ⸱ 17 Nov 2025 ⸱ 00h 56m 55s tldw: A back to basics talk that walks from a mutex and condition variable producer consumer queue through semaphores, atomics, memory ordering, and CAS to a practical lock free SPSC queue, worth watching if you want solid, practical concurrency knowledge.
4. [**"Command Line C++ Development - Mathew Benson - Meeting C++
