Have you ever been "nerd sniped"? When I realized that exceptions are capable of reducing binaries sizes, it felt like the only thing standing in the way of its adoption was its performance concerns. I couldn't let it go. I wanted to see how far the algorithm could be pushed. In 2024, I set out to just that: making C++ exceptions blazingly fast for embedded platforms.

API Structure and Technique: Learnings from Code Review

C++ is a very versatile language for making APIs. This talk examines some API techniques -- mechanical and structural -- that I've introduced to production libraries, based on reviewing code where folks were trying to achieve their goals, but with suboptimal formulations. C++ was able to do better, albeit sometimes in non-obvious ways. We'll look at real code: dealing with the complexities of...

How to Tame Packs, std::tuple, and the Wily std::integer_sequence

Tuesday September 16, 2025 16:45 - 17:45 MDT

Template parameter packs and std::tuple unlock powerful metaprogramming capabilities in C++, but they also introduce a parallel sublanguage—one with unfamiliar rules, verbose idioms, and surprising limitations. Packs were originally designed for perfect forwarding, not compile-time iteration, which makes even simple tasks like filtering or transformation awkward. std::integer_sequence helps, but...

Summit 8/9

On top of the woes of multi-threaded programming itself, coding for GPUs used to be about dealing with kernels, separate memory domains, warps, blocks and other strange things. Later, life became easier and you could sprinkle in a bunch of pragmas, hoping that your favorite language extension would deal with all of this for you, and better memory model abstractions came up that were less painful...

Duck Typing, the C++ Way: How Type Erasure Bends the Rules

Friday September 19, 2025 09:00 - 10:00 MDT

Crest 3/4/5

Type erasure is one of C++'s most underrated yet powerful idioms - allowing you to write flexible, generic code while hiding concrete type information behind a unified interface. In this talk, we’ll dive deep into how type erasure enables runtime polymorphism without inheritance, and draw parallels to duck typing in dynamic languages, but with C++ static safety guarantees. In this talk,...

Back to Basics: Move Semantics

Friday September 19, 2025 10:30 - 11:30 MDT

Crest 3/4/5

While many C++ programmers are familiar with the broad idea of move semantics, even experienced C++ programmers often struggle with the fine details. For example, many programmers are unclear on exactly when an object is considered implicitly movable and when std::move() is required to make the object movable. This is especially unfortunate because using std::move() when it's unnecessary sometimes...

Beyond Sequential Consistency

Friday September 19, 2025 10:30 - 11:30 MDT

In 2011, C++ introduced a formally defined memory model, providing a foundation for portable, multi-threaded code with well-defined correctness guarantees. This was a major milestone, enabling expressive threading primitives and safe concurrency patterns while allowing low-level optimizations for performance. By default, C++ atomics enforce sequential consistency, which ensures intuitive,...

Type Traits without Compiler Intrinsics – The Promise of Static Reflection

Friday September 19, 2025 10:30 - 11:30 MDT

Summit 10/11

Type traits are a powerful feature of C++ that allows programmers to query and manipulate the properties of types at compile time. They are widely used in generic programming and metaprogramming to enable static polymorphism, type-based dispatching, and compile-time optimization. However, not all type traits can be implemented using the C++ language alone. Some type traits, such as std::is_class,...

Dynamic Asynchronous Tasking with Dependencies

Standard C++ provides std::async for launching asynchronous tasks, but its use in building complex parallel applications is severely limited by the lack of native support for task dependencies. In practice, many real-world parallel applications, such as those in scientific computing, data processing, gaming, trading, and electronic design automation, rely on tasks that depend on the completion of...

We rely on implicit conversions all the time, every day, in every C++ code base. We'll examine if this is really a good idea and some problems that implicit conversions can cause.

Hopefully we'll come to some conclusion what "good" vs "bad"...

With each new language standard, these capabilities have expanded — and C++20 took a big step forward by allowing dynamic memory allocation in constexpr functions via operator new. This made it possible, for example, to use...

Persistent data structures are used to implement immutable containers, so that they are manipulated by producing new values, leaving the old ones intact. To do so efficiently, these new values do not contain a copy of the whole structure. Instead only the changed parts are created new, and the rest of the structure is shared internally between old and new values. We call this structural sharing ...
