Memory bugs are tricky. Leaks have a clear impact on performance, and quickly become hard to spot when heap allocated objects move too much. Memory access bugs, on the other hand, make your program crash right away, if you’re lucky. In less desirable cases, they may end up corrupting random objects on the heap, and […]

Python is a handy all-purpose language. It can make you very productive within a short time period and has powerful expressiveness for data manipulation and processing. Yet, it’s not a great fit for lots of tasks. C++ is far better at achieving anything that needs bare metal performance, deterministic timing, or low-level access. Thankfully, some […]
Up until now, Qt 3D was relying on OpenGL for rendering. With the upcoming Qt 6, Qt will come with a rendering abstraction layer (Rendering Hardware Interface or RHI) to target not only OpenGL but also Vulkan, Metal and DirectX. We are in the process of adding RHI support to Qt 3D. This will allow […]
This is the story of a bug in an open-source project I maintain; as the maintainer I review and sometimes fix bug reports from the community. Last week, a user reported that the ‘File’ menu of the application was not appearing on macOS. Some investigation showed this didn’t happen when using the default translation (i.e […]
