Is C++ really unsafe, or is the problem how we use it? Jesper Pedersen interviews Klaus Iglberger, author of "C++ Software Design Patterns," about modern C++ challenges and misconceptions. Klaus argues C++ can be safe with the right techniques, discussing why the community fears pointers, the importance of standard algorithms, modernizing legacy codebases, AI-assisted refactoring, and why keeping code simple reduces bugs and improves maintainability.

We start with a blog post: Static Assertions in Rust - a lightweight approach to implementing compile-time checks in Rust.

New videos include a Qt World Summit Keynote presented by Siemens Energy and KDAB, complemented by a Siemens Energy Showcase. Also included are Qt Widgets Part 9 plus two new Curious Developer Interviews hosted by Jesper Pedersen.

Latest Training and Event News complete the November update.

Join Jesper Pedersen at NDC Techtown 2025 for a conversation with Anders Schau Knatten—C++ expert, creator of cppquiz.org, and author of "C++ Brain Teasers." Anders discusses his journey from pub trivia to publishing, why low-level programming concepts matter, learning "just enough assembly," the importance of undefined behavior in C++, his favorite developer tools, and running live quizzes that stump even experts.

Struggling with CMake and build systems? This interview with Nicole Patricia Mazzuca, build expert at Remarkable and former Microsoft vcpkg contributor, explores C++ build tooling challenges. Nicole discusses developer opinions on CMake and introduces Rho - a new CMake library making builds simpler and more maintainable. Topics include vcpkg's dependency management and community-driven approaches to evolving C++ tools.

Our latest blogs, details on releases, relevant event information both past and upcoming, and training news.

Discover how Siemens Energy revolutionized their engineering process by developing the Plant Asset Manager (PAM). With KDAB’s Qt expertise, PAM became a centralized, scalable platform—streamlining asset data, facilitating collaboration, and empowering engineers to deliver reliable energy worldwide.

Maycon Stamboroski and Maurice Kalinowski, both from Qt Group, discuss the new features in Qt 6.10 with Jesper Pedersen. Along the way, a bit of background is added, including what Figma is, what Lottie is and what QGraphs can even do. The C++ side of things is also covered, and QRangeModel - the new kid on the block in model/view programming, is explored and explained.

Jesper Pedersen interviews Jason Turner, creator of the @cppweekly YouTube channel, about reaching 500 consecutive episodes and the evolution of C++ content. Jason discusses his workflow managing 200+ episode ideas, the importance of quality transcriptions, choosing topics through community feedback on GitHub, and preferring stream-of-consciousness recording. They explore career-changing episodes like "C++17 for the Commodore 64" and balancing best practices with cutting-edge language features.

This final episode of "Introduction to Qt Widgets" will end on a high note - a very high note even - namely by Jesper talking about event filters. Event filters are a super neat tool in Qt, with which you can do truly amazing things - but also shoot yourself in the foot, so your whole leg falls off.

Join Jesper Pedersen from KDAB and special guest Jan Marker (October 2025), as they dive into the latest updates for the Qt AI Assistant in Qt Creator since their last recording in April.

In the previous episode, we learned how to add drag and drop to a widget. We could now take that knowledge and add drag and drop to list views, tables and tree views, but that would be quite a bit of work. Fortunately, QAbstractItemView (which is the super class for those three) does already have support for it.

In this episode, we will learn how to add drag and drop facilities to your application, both so it can work with other applications, but also so you can drag, possibly even complex data, around inside your application.

In this video, you will learn how to let the user drop files onto a Qt widget. The users of your application will appreciate being able to open a file by dragging it from a file manager (for instance), and dropping it onto your application.

Merge or rebase? Why not both? In this video, Nicolas shows how to work on parallel Git branches without having to switch between them thanks to Git's `--rebase-merges` feature.

In this final episode on AI-driven software development, I sit down with a lawyer to discuss the legal questions that come with using large language models (LLMs) in programming. From copyright issues to company policies, we’ll cover the key challenges every developer should be aware of.

Find out how AI tools have helped KDAB's CEO maximize his coding time.

In this episode Jan will show us a bit of the Qt Creator integration QodeAssist, and we will discuss the existence of tools like Cursor and Windsurf.

Jan demos the new agent mode in Visual Studio Code, exploring how it works in practice. He shows how it handles a real change request from Jesper, and discusses the overall takeaways from the experiment.

In this episode, we explore how Large Language Models (LLMs) work behind the scenes — from predicting the next word to powering tools like GitHub Copilot. Jesper introduces insights from his master’s thesis, Jan explains the core mechanics, and we discuss how agents extend LLMs beyond simple text generation.

In this episode, we explore how to host and run your own Ollama models on a dedicated server, from setup to integration. We discuss the difficulty of self-hosting, how Ollama works, its scalability, and the available model repository. You’ll also see a live demo, watch Jan interact directly with a model, and learn how to connect Qt Creator to your own hosted model.
