September 2025 - Events Overview |
|
|
|---|
|
September is packed with standout events for the developer and embedded systems communities, offering opportunities to exchange ideas, learn from real-world projects, and explore emerging technologies across Europe.
The month begins with KDE Akademy (Sept 6–7, Berlin), the annual conference of the KDE community. Held both in-person and online, Akademy brings together contributors and users to discuss the future of KDE technologies, community initiatives, and free software collaboration.
In mid-September, Oxidize (Sept 16–18, Berlin) brings Rust professionals together for a deep dive into how the language is being applied in production. The event highlights real-world use cases and the growing role of Rust in safety-critical and performance-sensitive applications.
Next up is NDC TechTown (Sept 22–25, Kongsberg, Norway), a popular conference for C, C++, and embedded development. Combining hands-on workshops and talks, it offers a space for engineers to explore everything from low-level optimization to system design. If you're interested about KDAB at NDC TechTown, you'll find more info here.
The month concludes with Fluttercon Europe (Sept 24–26, Berlin), a dedicated conference for the Flutter and Dart ecosystem. Expect expert talks, in-depth workshops, and a strong focus on cross-platform UI development—from mobile to embedded.
Whether you're looking to connect with open source communities, expand your language expertise, or explore new frameworks - September has you covered. You can find more details at the bottom of this newsletter. |

Bjarne Stroustrup joins Jesper Pedersen for a focused discussion on C++. They cover who C++ is for, contrast static and dynamic reflection, and explore core design principles that guide the language’s evolution. Stroustrup also touches on pattern matching and the role of modern modular imports like import Qt in streamlining development. Watch the full interview. |  | At Qt World Summit 2025, Jesper Pedersen speaks with Volker Hilsheimer and Maurice Kalinowski about Qt’s evolving direction. They explore hybrid UIs combining Qt Widgets and QML, upcoming improvements to Qt Bridge, and expanded hardware acceleration for 2D graphics. The conversation also touches on the future of Model/View architecture and how Qt is preparing for AI integration across its ecosystem. Watch here. |
|
|  | At Qt World Summit 2025, Jesper Pedersen sits down with Troll #4, Paul Olav Tvete, for a lighthearted retrospective on Qt’s 30-year journey. They recount early milestones, like Trolltech’s unexpected strain on Norway’s internet and the quirky logic behind opening an office in Australia. It’s a nostalgic and humorous look at the lesser-known moments that shaped Qt’s history. Watch the video. |  |
