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 2025!

Lightning Talk: From Macro to Micro in C++

by Conor Spilsbury

Summary of the talk:

Our continuous real-time monitoring led us to investigate an anomaly in the data about our system's performance. This led us to investigate and identify the culprit: a specific data structure used in our code and the way that structure was being initialized.

To Int or to Uint, This is the Question

by Alex Dathskovsky

Summary of the talk:

In our daily work, we often use integral data types to perform arithmetic calculations, but we may not always consider how the selection of the data type can affect performance and compiler optimizations. This talk will delve into the importance of choosing the correct data type for the job and how it impacts compiler optimizations. We will also examine the overall performance implications for the application. We will explore specific algorithms where using unsigned data types is more beneficial and other situations where signed data types are the best choice. Furthermore this talk will dive into the differences between signed and unsigned integers, how the processor handles certain operations and explain many of the surprising pitfalls of using integral types.

Attendees will come away with a deeper understanding of how data type selection can impact their code and how to make better choices for optimal performance.

This session will follow the guidelines from my short article on LinkedIn but it will go into higher details and contain more examples and explanations.

When Nanoseconds Matter: Ultrafast Trading Systems in C++

by David Gross

Summary of the talk:

Achieving low latency in a trading system cannot be an afterthought; it must be an integral part of the design from the very beginning. While low latency programming is sometimes seen under the umbrella of "code optimization", the truth is that most of the work needed to achieve such latency is done upfront, at the design phase. How to translate our knowledge about the CPU and hardware into C++? How to use multiple CPU cores, handle concurrency issues and cost, and stay fast?

In this talk, I will be sharing with you some industry insights on how to design from scratch a low latency trading system. I will be presenting building blocks that application developers can directly re-use when in their trading systems (or some other high performance, highly concurrent applications).

Additionally, we will delve into several algorithms and data structures commonly used in trading systems, and discuss how to optimize them using the latest features available in C++. This session aims to equip you with practical knowledge and techniques to enhance the performance of your systems and make informed decisions about the tools and technologies you choose to employ.

CopperSpice: C++20 and Two's Complement

New video on the CopperSpice YouTube Channel:

C++20 and Two's Complement

by Barbara Geller and Ansel Sermersheim

About the video:

Someone mentioned C++20 is unusable because the standard now requires 2' Complement. Is is possible that he has a point and if so, on what basis did he make this claim?
