C++Now 2021 Videos



And now a word from our sponsor, JetBrains:

Generally regarded as the year’s most academic event in the C++ community, C++Now moved to an online format in 2021 without losing any of its most distinctive qualities. It offered insightful discussions about some of today’s hottest topics, like C++ ABI stability, CMake, C++20 modules and concepts, and more. Together with Bloomberg, JetBrains is proud to support the event as a video sponsor and bring you early access to this year’s conference recordings!

We will be publishing the talks over the course of several weeks on this page. All the talks will later be available on the C++Now YouTube channel. Can’t wait to watch the first recordings from the event? The first talks are already available on the page, and more recordings are coming in the next month!

The C++Now YouTube Channel

Fans of C++Now videos know that all BoostCon and C++Now session recordings have always been available free on our YouTube channel. This continues to be our policy. We are showing our appreciation to JetBrains for their valuable support for C++Now and the C++ community by allowing them a brief window of exclusivity in access to this year’s videos.

For those that are interested in such details, the videos that are embedded on the JetBrains page are the same ones that will eventually be made public, so the URLs will not change and views on the JetBrains page will be included in the video view counts shown in our channel when the videos are made public there.

You may also notice that ads will begin to appear with the videos on our channel. Our policy has always been that C++Now and BoostCon videos should appear ad-free. We’d like to continue this policy, but YouTube’s policies have changed and they no longer allow us to offer the videos ad-free. This is a YouTube decision, not one of the Boost Foundation, C++Now, or any of our sponsors.

Until we see you again next May, enjoy the videos!


Announcing C++Now 2022



Wrapping up C++Now 2021 and announcing C++Now 2022

C++Now 2021 was our first and only online conference experience. With over two hundred attendees, we exceeded our previous attendance record by sixty percent.

Keynote Announced: Bryce Adelstein Lelbach



Keynote Speaker Bryce Adelstein Lelbach

The Boost Libraries, which brings you C++Now, was established to “foster C++ standards activity by helping to establish existing practice,” so it no surprise that we’d ask the question, What Belongs In The C++ Standard Library?

This is the title of the C++Now 2021 Closing Keynote given by our own Bryce Adelstein Lelbach.

For decades, the C++ community and committee has struggled with this question. In his talk Bryce will consider if the Standard Library should be large and all encompassing or small and focused? He will present the history of the Standard Library’s scope, from the days before the first C++ Standard, to Stepanov’s STL, to Boost, the long C++0x era, and the last decade of regular C++ Standard releases.

Bryce will present his answer to the question and outline the principles that he believes should guide stewardship of the C++ Standard Library.

In addition to serving as NVIDIA’s HPC Programming Models Architect, where he leads programming language standardization efforts and drives the technical roadmap for NVIDIA’s HPC compilers and libraries, Bryce also serves a Program Chair for C++Now. It is generally considered best practice for conferences like C++Now, to not have a serving Program Chair as keynote speaker, but as chair of the Standard C++ Library Evolution working group (LEWG), Bryce may be the individual that is most directly tasked with dealing with this question.

The role of LEWG is processing and refining new library proposals, so the question what belongs in the library? is not just a philosophical exercise, but a practical driver for decisions that Bryce puts to the working group.

Don’t miss this opportunity to understand the principles that are shaping the evolution of the C++ Standard Library.

The C++Now 2021 Program Committee is pleased to announce that the 2021 Conference Schedule is now online.  We have a great, fully-online program this year with 3 tracks and 49 C++-focused sessions, including keynotes, regular sessions, library-in-a-week, lightning talks, and the traditional closing panel.  If you’re still on the fence about whether to join us, now is the time to check out the schedule, last year’s attendee video, and join us now.


Keynote Announced: Tony Van Eerd



Keynote Speaker Tony Van Eer

C++Now is celebrating the 20th birthday of SOLID by asking one of our most popular presenters to give a keynote address on the SOLID Principles, which were introduced in 2000 (and were around individually long before coalescing into the nice acronym).

Tony has won so many “Best Presenter” awards at previous C++Now events that they’ve been called the Tony Awards. His style is entertaining and engaging, but he brings to his presentations a wealth of insight and experience. He’s been called both a Ninja and a Jedi.

After 2000, The SOLID Principles quickly became tenets of OOP (Object Oriented Programming). But much has changed in these 20 years, and VOP (Value-Oriented Programming) has been pushed by some as the better way (or at least as another tool in the tool box). Does SOLID hold up in the VOP world? Does it still apply? Come to Tony’s talk and find out.

Tony Van Eerd

Tony has been coding for well over 25 years working on lots of pixel++, UX, threading, etc. Previously at Inscriber, Adobe, BlackBerry, he now enables painting with light at Christie. He serves on the C++ Committee where his Tony Tables have become part of the culture.

Tony’s keynote will delve into the original (and sometimes forgotten) motivations and goals behind SOLID. It will (of course) explain what each of the letters of SOLID stand for, and how they apply to OOP (and how they have been distorted in OOP). In particular, we will look at how and whether SOLID applies to Value Oriented Programming and how SOLID fits into modern C++.

Keynote Announced: Bill Hoffman



Keynote Speaker Bill Hoffman

CMake has emerged as the dominant build manager for C++ projects and this year we have the original CMake author as our opening keynote speaker.

Bill Hoffman is a founder of Kitware and currently serves as Chairman of the Board, Vice President, and Chief Technical Officer (CTO). He is the original author and lead architect of CMake, an open source, cross-platform build and configuration tool that is used by hundreds of projects around the world, and he is the co-author of the CMake reference, Mastering CMake.

Bill’s opening keynote address is entitled CMake: One Tool To Build Them All and will give the history behind CMake and explain how it fits into the areas not specified by the C++ standard, enabling developers to take advantage of the rich C++ ecosystem. The talk will introduce users to important CMake features supporting the seamless building, testing and deployment of C++ across most computing platforms.

Mastering CMake

The talk is about how CMake fits into the C++ world. Bill will describe how CMake is more than just a build system, but a tool chain that transforms C++, C, Fortran, CUDA, and C# code into a final, shippable product.

The heart of CMake is the codification of the complex knowledge between the C++, C, and Fortran language standards, and the diversity of available compilers, linkers, archivers, packagers, run-time loaders, and operating systems. CMake’s ability to encode translation and artifact unit dependencies, manage language levels and compiler parameters via usage requirements, and support the mixing of multiple languages seamlessly are all designed to support the driving purpose of CMake: “to build software everywhere, correctly, with the user’s preferred tools.”
