If you’ve read the first article in this series, you’ll know what full stack tracing is and why you definitely want it. This time, we’ll show you how to setup full stack tracing on your Linux system. There are two steps – first get everything configured to capture a trace, and then view and interpret […]

Full Stack Tracing Part 1 What is it and when is it useful?
Full stack tracing is a tool that should be part of every software engineer’s toolkit. It’s the best way to investigate and solve certain classes of hard problems in optimization and debugging. Because of the power and capability it gives the developer, we’ll be writing a series of blogs about it: when to use it, […]
Qt Desktop Days 7-11 September KDAB hosted online event
We are happy to let you know that the very first edition of Qt Desktop Days 2020 was a great success! Having pulled together the event at very short notice, we were delighted at the enthusiastic response from contributors and attendees alike. Over 500 registered attendees could enjoy five days of technical talks. The program shows […]
How to Build C++ Projects with the Address Sanitizer on Windows memory bug detection via compiler extension
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 […]
Heaptrack Version 1.2.0 Released Maintenance release of the fast Linux heap memory profiler
We have just released version 1.2.0 of Heaptrack, the fast heap memory profiler for C++/Linux applications. A bit of Background The Heaptrack fast heap memory profiler allows you to track all heap memory allocations at run-time. Afterwards, you can use the accompanying GUI tool to find optimization opportunities in your code by analyzing the recorded […]

This year’s online conference features eleven talks in one track. On November 14th you can see a talk from KDAB’s Marc Mutz: Partially-Formed Objects […]
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 […]
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 […]
CMake for Qt Basics on using CMake for Qt applications
The build system for Qt 6 is moving to CMake. Should you use it yourself? What are the benefits of CMake, and how can it help transform your build system? Here are the basic facts you need to know to take advantage of CMake for building Qt applications.
