Creating Python bindings for Qt libraries
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 […]
Qt 3D will be ready for the Qt 6 release
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 […]

One of the most difficult choices when starting any new software project is selecting the programming language and framework your team will use to create it. Should you stick with Qt because it’s the best tool for the job? Should you switch to something using web- based technology or designed explicitly for mobile? This whitepaper […]
Choosing a CPU Is the i.MX 8 right for your project?
When building an embedded systems product, among your earliest decisions is the choice of hardware. More specifically, on what CPU should you base your design? Today’s system-on-chip processors have a huge array of resources to contribute to your solution: multiple cores and on-board DSPs, graphics engines and display controllers, peripheral support and connectivity interfaces, and […]
Containers whitepaper Cloud tech comes to embedded
Software developed for embedded applications is often distinct from its desktop and cloud cousins due to the constraints of embedded hardware and the integration of non-mainstream devices. But problem-solving technologies developed in other places tend to migrate to embedded systems once the hardware catches up. Containers are one of these – and they’re not just […]

Blogs My file menu is not full of eels by James Turner 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 English), but a bit more investigation showed that it only happened when the language […]
