This is a session for those interested in visiting the "Deciphering Coroutines" on Thursday. That talk will assume prior familiarity with the C++20 coroutines feature and build heavily on the first "Deciphering Coroutines" talk from CppCon 2022.
If you have not seen the 2022 talk and are not yet familiar with C++20 coroutines, come to this session for a quick recap of the basics. We will do a detailed introduction to coroutines and get you up to speed with everything that you need to know to follow the presentation on Thursday.

Kris will explain Bitcoin Script, a stack-based scripting language integral to Bitcoin's transaction validation process, Bitcoin Script plays a crucial role in defining custom transaction rules and smart contract functionalities. He will explore the inner workings of Bitcoin Script from a technical standpoint, focusing on its implementation details in C++.
Attendees will gain insights into key concepts such as opcodes, stack operations, and the evaluation engine, as well as security considerations for safe script execution. Additionally, practical use cases will be examined to demonstrate Bitcoin Script's real-world scenarios.

As C++ developers, we will have the opportunity to work on many different teams and many different projects throughout our careers. We may sometimes work on a team that’s enjoyable, but isn't delivering too much. Other times, we might work on a team that delivers, but is no fun. If we’re really unlucky, we can end up on a team that doesn’t deliver and isn’t enjoyable. But occasionally, we can have the privilege of being part of a team that not only delivers, but is also a great team to be on.
The ability of us, as individual contributors within a team, to work together effectively is critically important. Often more so in C++ than in many other languages, due to the scale and complexity of the solutions we are often trying to deliver. This ability of individual contributors to work together collaboratively as a team is often not related to their C++ skills and knowledge.
This talk will explore the different characteristics of software development teams, and will look at the different roles and responsibilities within a team. Taking an evidence-based approach, we’ll consider what makes a good team, explore how to encourage more cooperative teamwork in order to achieve better results for everyone on the team, as well as offer some ideas for how to gently improve the teams on which we are currently working.

Introducing xstd::any<N, Features...>, an extension of C++17’s std::any, designed to be a type-safe, owning container that can handle any data type with enhanced functionality. xstd::any can be configured with additional features such as comparability, hashability, and streamability, making it ready for use in std::map, std::unordered_map, and for output operations. This template-based implementation utilizes small object optimization to store types smaller than N bytes directly, avoiding heap allocation and minimizing dynamic memory overhead. The presentation will explore the internal design and implementation of xstd::any<>, focusing on how it manages memory efficiently and maintains value semantics even when dynamically allocating larger objects. The session will showcase practical use cases, demonstrate usage with standard C++ containers, and explore the recent C++ features that enhance its functionality. Like std::variant or std::tuple, xstd::any requires mechanisms to handle various contained object types seamlessly. We will discuss the addition of stream operators, hash functionality, and comparison operators, enhancing its usability across different programming scenarios.
Outline: * Requirements: Understanding the needs for a versatile container like xstd::any, compared to other generic container types. * Example Use Cases: Demonstrating practical applications and benefits. Implementation and Memory Layout: Deep dive into technical details and optimizations. * Testing: Approaches to ensure reliability and performance. * Exception Safety: Handling errors and exceptions. * Interaction with std:: Containers: Integration strategies and examples. * Question & Answers: Open floor for audience queries and discussions.
Presentation Materials & Source Code: All resources, including detailed presentation slides and the source code, are freely available on GitHub for further exploration and testing.
Lightning talks are your five minutes of stardom. The format encourages a focused and often high-energy presentation about nearly anything (subject to approval by the conference) that might be interesting to the C++ community, including proprietary technologies. They can be of a lighter or humorous nature, but they need not be.
