static_vector is a std::vector that allocates things on the stack instead of the heap. We have std::vector, so it should be easy to write a non-allocating version, right?

Sadly, it's not quite that simple. There are many aspects of the vector interface that make sense based on a container that can reallocate, but do not make sense for a container that cannot. This leads to some API differences. static_vector also faces certain challenges around constexpr that makes it both more and less constexpr than std::vector.

We will go into detail on how std::vector and how static_vector work, how they are similar, and how they differ. This presentation will be focusing on lower-level details and interactions with specific language features in C++20 and (hopefully) C++23. There will be lots of code examples, and we'll step through how they work and where they fall short, trying to build up to a working, production-ready solution.

Three-dimensional graphics are much simpler than you would think. I will present the rudimentary techniques for the designs of a simple C++ Matrix library and operator methodologies, through an introduction to 3D Graphics: Points, Vectors, Coordinate Spaces, Matrix Math, Depth Buffer and Rasterization.

We will explore the blood and guts of a C++ Matrix library and 3D graphics. Rather than using off-the-shelf libraries like Unity and OpenGL, we will examine a simple library I wrote to teach myself about the subject. Includes demo of the graphics library/app.

This session is part of the Software Design Track.

Many engineering disciplines require alterations or improvements of existing systems to be "up to code," whether that be the installation of railings on a staircase or upgrades to electrical work. In this talk, we'll apply this concept to Software Engineering and, in particular, C++-based systems. Using one real-world example, we'll cover best practices including: contracts, type-driven architecture, hierarchical design, and difficult testing scenarios as they apply to "old work."

While many of these topics are covered elsewhere, they are usually presented as if all code is being written from scratch. Application to an existing system is an entirely different matter. That is the subject of this talk.
