Registration is now open for CppCon 2023! The conference starts on October 1 and will be held in person in Aurora, CO. To whet your appetite for this year’s conference, we’re posting videos of some of the top-rated talks from last year's conference. Here’s another CppCon talk video we hope you will enjoy – and why not register today for CppCon 2023!

Lightning Talk: Finding Whether a Number is a Power of 2

by Ankur Satle

Summary of the talk:

I asked this question on social media and got many diverse responses. I will present the various approaches and compare them. I will finish with the options C++20 provides with the bit header. https://en.cppreference.com/w/cpp/numeric/has_single_bit

Back to Basics: Templates in C++

by Nicolai Josuttis

Summary of the talk:

Templates are among the most powerful features of C++, but they remain misunderstood and underutilized, even as the C++ language and development community have advanced. This talk shows when and how to use modern templates to build software that's cleaner, faster, more efficient, and easier to maintain. We will cover all basic aspects of templates you have to know when programming generic code in Modern C++

CppCon 2022 import CMake, CMake and C++20 Modules -- Bill Hoffman

import CMake, CMake and C++20 Modules

by Bill Hoffman

Summary of the talk:

Originally developed as part of the National Institutes of Health (NIH) open source medical segmentation and registration toolkit ITK in 1999, CMake has grown to take on a vital role in the C++ ecosystem. Bill Hoffman, a founder of Kitware (www.kitware.com), and the creator of CMake will talk about where CMake is in 2022. The talk will start with a brief history of CMake and how it fits into the world of C++. It will then talk about recent developments to support C++20 modules.

For most of CMake's history, CMake has played catch up and implemented new features as compilers and IDEs have been released. With C++ modules, CMake developers have engaged the standards committee and compiler vendors to help craft the standard in such a way that CMake and other build systems can more seamlessly implement C++ modules. CMake has worked with Fortran modules for many years and has updated the ninja build tool to be able to dynamically update dependency information as it is discovered. To do this CMake requires a Fortran parser built into CMake. For obvious reasons CMake does not want to get into having its own C++ parser. This is the main driving force for pushing this work into the compilers. This talk will go over the road map for CMake C++ module support.

In addition to the history of CMake, C++ module support, this talk will include material covering important CMake features supporting the seamless building, testing and deployment of C++ across most computing platforms. In summary, listeners will learn about CMake origins, the roadmap of C++ module support in CMake and get an overview of the current set of features in CMake.
