CppNorth, The Canadian C++ Conference 2025

TBA

In this talk, we will explore the power of C++20 ranges and how custom views can simplify complex data transformations and improve code expressiveness. By creating reusable, lazy-evaluated views that operate on ranges, developers can avoid unnecessary intermediate containers and simplify complex data transformations. While standard views like std::views::transform and std::views::filter offer powerful tools for basic operations, custom views provide additional flexibility, allowing developers to create highly specialized transformations and handle more complex, state-dependent logic.  Through real-world examples, we will demonstrate how custom views enhance performance and maintainability, showcasing how they can streamline everything from basic filtering to complex, state-dependent transformations in modern C++ applications.

C++ has stricter rules for running code in constexpr mode. This talk intends to explore those restrictions while offering paradigms for designing data structures that are constexpr compatible, and which will be demonstrated as having potent applications.

Writing an emulator is truly transformative for any aspiring developer. In this session, we will be building parts of a lightning-fast Nintendo GameBoy (DMG-001) emulator library.
We will introduce the concept of a 'fast' emulator, highlighting its significance beyond mere gaming authenticity. After setting clear limits as to what we aim to achieve within the allotted time, we will delve into some foundational aspects of modern computing by implementing the core components of a GameBoy emulator.

Additionally, we will demonstrate how integrating modern high-level C++ constructs streamlines our codebase, enhancing both readability and performance. You will witness firsthand how these constructs simplify development and yield significant speed enhancements (even when applied to emulating low-level systems).

This session aims not only to provide practical insights into modern emulator construction but also to invite collaboration on future enhancements and optimizations.
