Making the Most of your Memory with mmap

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 […]

GammaRay 2.10.0 Release

We have released version 2.10.0 of our Qt application introspection tool GammaRay. GammaRay allows you to observe behavior and data structures of Qt code inside your program live at runtime. GammaRay 2.10 comes with an entirely new inspection tool for QtLocation geo positioning data. Besides visualizing the currently provided positioning data on a map, it […]
