Mixing C++ and Rust for Fun and Profit: Part 1 Or why switching to Rust is such a large undertaking
For quite some time, I have been bothered by this thought: Individual programming languages (C++, Rust, Go, etc.) are traditionally viewed as walled gardens. If your main() function is written in C++, you had better find yourself C++ libraries like Qt to build the rest of your codebase with. Do you want to use Flutter […]

Projection Matrices with Vulkan – Part 1 How transformations differ from OpenGL to Vulkan
This post explains the difference between OpenGL and Vulkan transformations and how to adapt code to get the desired results, plus actually understanding what's going on.
Supercharging VS Code with C++ Extensions
In a previous blog we demonstrated the most straightforward method to optimize Visual Studio Code for a Qt / C++ environment: simply let the tools do all the work! The example GitHub project we discussed automatically installs both the Microsoft C/C++ and clangd extensions into VS Code. You might wonder why you need both C++ […]
Qt for VS Code, the TL;DR version Using VS Code IDE to work on Qt project

PSA: QPointer has a terrible name
Today’s blog post is about a small utility class in Qt with a… questionable name: QPointer. If you’re new to Qt, maybe don’t check out QPointer’s documentation just yet, and try to guess what the class does based on its name alone. I’ve seen countless users being very confused by it. Some end up using […]
