Synchronization in Vulkan

=> ↺ Synchronization in Vulkan

An important part of working with Vulkan and other modern explicit rendering APIs is the synchronization of GPU/GPU and CPU/GPU workloads. In this article we will learn about what Vulkan needs us to synchronize and how to achieve it. We will talk about two high-level parts of the synchronization domain that we, as application and library developers, are responsible for: [...]

Review use of Qt module header includes

=> ↺ Review use of Qt module header includes

Having come across sources using include statements for some Qt module headers (like #include ), memories arose about a check from the static analyzer tool krazy as once run conveniently on KDE's former ebn.kde.org site. That check, called includes, poked one not to use Qt module headers. Due to resulting in the inclusion of all the headers of those modules, and then again that of the other Qt modules used by the module. Which them meant more stuff to process by the compiler for compilation units with such module header includes.

So is that perhaps in 2023 no longer a real-world noticeable issue? A first look at some preprocessor outputs (with Qt5) for a single line file with just an include statement hinted though it might still be true: [...]
