CppCon 2022 Keynote: How C++23 Changes the Way We Write Code by Timur Doumler Live, In Person

We’re happy to announce: Timur Doumler will be in Aurora live, in person to deliver key insights on C++23 best practices.

Timur DoumlerHere is the abstract for Timur’s talk:

C++20 was a huge release: coroutines, concepts, ranges, and modules profoundly changed the way we write code and think about C++. In comparison, C++23 is a lot smaller in scope: its primary mission is to complete C++20, to fill holes, and to fix issues. Nevertheless, some great new features made the cut this time around, both in the standard library and in the core language. This is even more remarkable considering that the entire feature design phase of C++23 took place during the COVID-19 pandemic, challenging the ISO C++ committee to completely reinvent how we work together.

This is not a firehose talk about C++23 that tries to cram as many additions and improvements as possible into one hour. Instead, we deliberately focus on just a handful of new features that are going to noticeably change and improve the experience of the everyday C++ programmer. We will talk about how `std::expected` improves error handling, the huge impact that `std::mdspan` will have on scientific computing, how deducing `this` greatly simplifies longstanding C++ idioms such as CRTP, and how `std::print` will forever change how we write “Hello, World”.

Timur is the Developer Advocate for C++ tools at JetBrains and an active member of the ISO C++ standard committee. As a developer, he worked many years in the audio and music technology industry and co-founded the music tech startup Cradle. Timur is passionate about building inclusive communities, clean code, good tools, low latency, and the evolution of the C++ language.

Registration is now open. Tickets are now available for both online attendees and in-person attendees.

CppCon 2022 Online Keynote: Principia Mathematica by Lisa Lippincott Live, In Person

Lisa Lippincott will be online for a talk that takes its title from Bertrand Russell’s and Alfred North Whitehead’s logicist tour de force, Principia Mathematica.

Lisa LippincottHere is the abstract for her talk:

The C++ integral arithmetic operations present a challenge in formal interface design. Their preconditions are nontrivial, their postconditions are exacting, and they are deeply interconnected by mathematical theorems. I will address this challenge, presenting interfaces, theorems, and proofs in a lightly extended C++.

This talk takes its title from Bertrand Russell’s and Alfred North Whitehead’s logicist tour de force, Principia Mathematica. It echoes that work in developing arithmetic from first principles, but starts from procedural first principles: stability of objects, substitutability of values, and repeatability of operations.

In sum, this talk is one part formal interface design, one part tour of C++ integral arithmetic, one part foundations of arithmetic, and one part writing mathematical proofs procedurally.

Lisa Lippincott designed the software architectures of Tanium and BigFix, two systems for managing large fleets of computers. She is chair of the numerics study group of the C++ standardization committee.

Registration is now open. Tickets are now available for both online attendees and in-person attendees. Register today!

Instructor Interview: Fedor Pikus / Performance and Efficiency in C++

Instructor Interview: Klaus Iglberger / Modern C++ Design Patterns

In this instructor interview, Kevin Carpenter welcomes Dr. Klaus Iglberger for a discussion of his CppCon Academy class, Modern C++ Design Patterns, which will be onsite in Aurora, Colorado.

Klaus is an international C++ trainer, initiator and lead designer of the Blaze C++ math library, the organizer of the Munich C++ user group, and creator and co-chair our own Software Design Track.

Klaus and Kevin discuss how this class has evolved in the years since Kevin attended it. The class has been updated to cover new C++20 features, but the emphasis is on structure and dependencies rather than features.

Klaus also announces his new book book which can be used as a reference for this class.

In addition to this class, Klaus will be doing two Main Program sessions: Breaking Dependencies: The Visitor Design Pattern in the Software Design Track and Back to Basics: Value Semantics in the Back to Basics Track.

CppCon 2022 Program Announced

The Main Program for CppCon 2022 is now live!

This year, CppCon is a hybrid format, so we are presenting four tracks for onsite attendees and five tracks for online attendees.

Online attendees will be able to participate in onsite sessions via “simul-cast” for most sessions. (Online attendees with On-Demand Session Access will have the ability to view recorded versions of all sessions–onsite and online–shortly after they happen.)

We’ll have over seventy breakout sessions delivered onsite and fifty additional remote sessions by the best C++ presenters in the industry, many returning from previous years as well as some exciting new voices, some of whom are able to present only because we are offering a remote presenting possibility. In addition, we’ll present our traditional onsite plenary session every day and an online opening keynote. We’ve already announced our onsite Opening Keynote and three other plenary talks and will be announcing our other two headline talks here in coming days.

This year’s Main Program features five special tracks including the Back to Basics Track, the Embedded Track, the Software Design Track, and the band new Scientific Computing Track and Tooling Track.

In addition to the Main Program, we’ll have the panels, lightning talks, Open Content talks, BOFs, exhibitors, social events, and classes that attendees have enjoyed in past years.

Most of the program is published, but we are still working a few surprises, so keep checking back.

We’d like to thank the Program Committee, our speakers, and the many professionals who proposed talks which we, unfortunately, just couldn’t squeeze in this year. Thank you for your hard work and enthusiastic support for this year’s program!

We hope to see you all in less than a month so register now.

Meow Wolf Field Trip Announced

The CppCon 2022 Field Trip will be an adventure into four alien worlds, joined together in a rare cosmic event, Meow Wolf‘s  Convergence Station.

Meow Wolf is a Santa Fe based arts and entertainment company that creates large-scale interactive and immersive art installations and we are going to their very popular new Denver installation, Convergence Station.

This adventure is not just a sensory overload, but an amazingly interactive experience.

After our journey, we will stop by Denver’s iconic Little Man Ice Cream in the LoHi district to cool off and enjoy some excellent ice cream.

Started in 2008 in a milk can shaped building, it has been serving ice cream in the Lower Highlands neighborhood.

Known for fine crafted favorites and unique flavors, it has taken the city by storm, opening several satellite locations.


Spend a fun-filled Sunday on September 11th with fellow attendees as explore these alien worlds and enjoy a Denver culinary tradition.

If you are arriving for CppCon 2022 by Sunday morning, this is your opportunity to get to know some of your fellow attendees while experiencing a uniquely Denver experience.

Erik Rainey live in person at CppCon 2022

Erik Rainey will be in Aurora, live in person to deliver a keynote address on C++ in embedded firmware.

Erik is a Senior Software Engineer at Amazon working in the Prime Air on low-level/embedded firmware written in C++ for drones. He’s also been a contributor to Khronos’s OpenVX 1.0 specification.

In his talk he’ll show some video of delivery drones in flight and discuss what it takes to make drones fly with C++. (See the video below.)

Here is his talk description:

Using C++14 in an Embedded “SuperLoop” Firmware

Erik RaineyThis presentation covers what the execution environment of an embedded “superloop” firmware is in order to describe later why certain C++14 language and library features are used and others are not. This environment lacks many basic features and capabilities that traditional C++ programmers may think are common place but is able to be programmed in C++14 (and later) with a specific design paradigms and guidelines. Programmers with deeply embedded C experience will be familiar with some of the limitations of the environment but may find the C++ solutions quite refreshing! The talk will conclude with some comments on C++17 / C++20 features which will be quite valuable to embedded environments of all types.

Registration is now open so don’t miss out on CppCon 2022 this September 11-16. Register today! Tickets are now available for both online attendees and in-person attendees.

Daniela Engert live in person at CppCon 2022

Daniela Engert will be in Aurora, live in person to deliver a keynote that takes us on a journey through modern C++.

Daniela has been building computers and creating software for over forty years, with thirty years in the field of applied digital signal processing. Her recent focus has been on modules and helping developers best understand them and their application in C++20. Here is her talk description:

Contemporary C++ in Action

This talk is different from typical conference presentations. Instead of focussing on one particular topic I want to take you with me on a journey where I put various pieces from the C++ landscape together into a small application and show how they fit together beautifully. My goal is to debunk the myth that the committee is looking to please experts and library developers instead of making life easier for the many developers in the trenches. This is not slideware, at the end of our tour the code will compile and run with some entertaining result.

On this journey, I will be visiting modules (using modularized popular libraries and others that constitute the app), do some network programming with coroutines (based on ASIO executors, as there are no C++ standard executors yet), slip in one or two of the flagship C++23 features, like explicit object parameters or some of the new library stuff, and season the stew with items from recent C++ standards. It’s a tiny application using techniques that an average programmer in the embedded or industrial world (like me) might find useful. The code I’ll show also contains very tiny fragments of condensed or simplified sources in active development taken from our in-house codebase – old and trusted, but thrust into the modern age.

Registration is now open so don’t miss out on CppCon 2022 this September 11-16. Register today! Tickets are now available for both online attendees and in-person attendees.
