An over-the-air (OTA) update capability is an increasingly critical part of any embedded product to close cybersecurity vulnerabilities, allow just-in-time product rollouts, stomp out bugs, and deliver new features. We’ve talked about some of the key structural elements that go into an embedded OTA architecture before. But what about the back end? Let’s address some […]

Using Nix as a Yocto Alternative Building a bootable Linux image from the ground up in a declarative way
Building system images for embedded devices from the ground up is a very complex process, that involves many different kinds of requirements for the build tooling around it. Traditionally, the most popular build systems used in this context are the Yocto project and buildroot. These build systems make it easy to set up toolchains for […]
The Smarter Way to Rust
If you’ve been following our blog, you’re likely aware of Rust’s growing presence in embedded systems. While Rust excels in safety-by-design, it’s also common to find it integrated with C++. This strategic approach leverages the strengths of both languages, including extensive C++ capabilities honed over the years in complex embedded systems. Let’s delve into some […]
KDGpu 0.5.0 is here! Our Vulkan wrapper now has OpenXR integration and more.
Since we first announced it last year, our Vulkan wrapper KDGpu has been busy evolving to meet customer needs and our own. Our last post announced the public release of v0.1.0, and version 0.5.0 is available today. It’s never been easier to interact with modern graphics technologies, enabling you to focus on the big picture […]
KDDockWidgets 2.1 Released Stability, Fixes, and Enhancements
KDDockWidgets has launched its latest version 2.1. This release comes packed with over 500 commits, offering enhanced stability over its predecessor, version 2.0, without introducing any breaking changes. KDDockWidgets is a versatile framework for custom-tailored docking systems in Qt written by KDAB’s Sérgio Martins. For more information about its rich set of features, have a […]
Hotspot v1.5.0 released The Linux perf GUI for Performance Analysis
Hotspot is a standalone GUI designed to provide a user-friendly interface for analyzing performance data. It takes a perf.data file, parses and evaluates its contents, and presents the results in a visually appealing and easily understandable manner. Our goal with Hotspot is to offer a modern alternative to perf report, making performance analysis on Linux […]
Mixing C++ and Rust for Fun and Profit: Part 3 How to not reinvent the wheel
In the two previous posts (Part 1 and Part 2), we looked at how to build bindings between C++ and Rust from scratch. However, while building a binding generator from scratch is fun, it’s not necessarily an efficient way to integrate Rust into your C++ project. Let’s look at some existing technologies for mixing C++ […]
Recursive Instantiation with Qt Quick and JSON Factory Design Techniques - Part 1
Recently I was tasked to come up with an architecture for remote real time instantiation and updating of arbitrary QML components. This entry shows how you can use a simple variation of the factory method pattern in QML for instantiating arbitrary components. I’ve split my findings into 3 blog entries, each one covering a slightly […]
Embedding the Servo Web Engine in Qt Using CXX-Qt to integrate a web rendering engine written in Rust
With the Qt WebEngine module, Qt makes it possible to embed a webview component inside an otherwise native application. Under the hood, Qt WebEngine uses the Chromium browser engine, currently the de facto standard engine for such use cases. While the task of writing a brand new standard-compliant browser engine is infamous as being almost […]
Streamlining Strategies for Embedded Software Development
Developing embedded software is notoriously difficult – how can we simplify the process? Fortunately, there are lots of techniques you can use daily to help streamline your development. Embracing Automation The specialized nature of embedded systems extends the ramp-up time for developers and necessitates a higher level of expertise. Automating hardware-specific tasks, such as deploying […]
