Sometimes it seems that we have nearly infinite memory resources, especially compared to the tiny 48K RAM of yesteryear’s 8-bit computers. But today’s complex applications can soak up megabytes before you know it. While it would be great if developers planned their memory management for all applications, thinking through a memory management strategy is crucial […]

Auto Innovation at Embedded World Nuremberg, Feb 26-28, 2019
In vehicle infotainment systems and instrument clusters are getting larger and more complex, requiring an exponentially growing base of software to drive them. Furthermore, KDAB finds that self-driving technology does not obviate the need for displays – in fact, autonomous technology seems to be accelerating the trend for larger and more capable graphics software. To […]

How to cast a function pointer to a void* a slightly-too-long-for-twitter report about a subtlety in C++
Question: How do you cast a function pointer to a void*? (You’re trustworthy and wouldn’t dare to do anything evil with it, right?) Answer: Maybe your first thought was, well reinterpret_cast<void*>(&f) of course. That was mine, at least. Well, it turns out, C++ wants to support architectures, where data and instruction pointers are physically distinct […]
qsslint – A linter for Qt stylesheets
Enter the wonderful world of tools for which the announcement blog takes more time to write than the tool itself. qsslint is a small command-line utility for verifying the syntax of your Qt stylesheet files (*.qss). It’s much like KDAB’s previous linter contribution, qmllint. It simply returns 0 if the stylesheet is valid, and non-zero […]
