November 2025

Welcome to the November 2025 edition! This month brings a focused mix of practical engineering insights, new learning resources, and fresh video content across Rust, Qt, and C++. 

First, a blog post covering a lightweight approach to implementing compile-time checks in Rust. 

Next KDAB highlights the newly released Qt World Summit 2025 keynote on platform engineering for large-scale energy systems, and a complementary showcase deep-dive video on Siemens Energy’s PAM platform.

You’ll also find the latest additions to the Qt Academy courses.

Furthermore, a showcase video on the afore-mentioned Siemens Energy project, new episodes of "The Curious Developer", and even a video version of last month’s newsletter.

Plus, check below for upcoming KDAB training courses and key events across Rust, Qt, and embedded development.

Static Assertions in Rust

Implementing Compile-Time Checks in Rust 
with a Simple Macro

Rust doesn’t include a built-in equivalent to C++’s static_assert, but you can achieve similar compile-time checks with a simple macro. This allows you to enforce conditions during compilation without external dependencies. While the Rust standard library has opted not to include such functionality, it's easy to implement and integrate directly into your own projects. Read on.

Qt World Summit 2025 Keynote

The Qt World Summit 2025 keynote, presented by Dacian Messthaler (Siemens Energy) and Till Adam (KDAB), is available to watch. The presentation explores how platform engineering can transform energy transmission solutions, tackling challenges in modularity, interoperability, and cross-functional collaboration. Key topics include designing and deploying composable infrastructure, creating a one-stop engineering portal that reduces cognitive load, integrating digital twin technology, and implementing data-driven engineering workflows to streamline development and operations across the energy ecosystem. Watch the keynote.

Making the Energy Flow: The Journey Towards a Qt Engineering Platform

Qt Academy - New Module

Part 9 of "Introduction to Qt Widgets"

Part 9 of KDAB’s course, “Introduction to Qt Widgets”, is now available on Qt Academy. This module builds on Part 8, covering advanced Model/View concepts including value-based models, proxy models for shaping data, and custom delegates for item display and editing. You’ll also learn how the selection system works across multiple views. The course consists of six focused lessons with a short knowledge check at the end. Sign up for free and get started or watch all the videos of "Introduction to Qt Widgets" on the KDAB YouTube channel.

KDAB Video Releases

Making the Energy Flow: The Journey Towards a Qt Engineering Platform

Complementary to the Qt World Summit 2025 keynote, KDAB has released a new video, “Making the Energy Flow: The Journey Towards a Qt Engineering Platform,” on their YouTube channel. The showcase takes a deeper look at Siemens Energy’s Plant Asset Manager (PAM) project, showing how KDAB’s Qt expertise helped transform it into a centralized, scalable platform. PAM now streamlines asset data, enhances cross-department collaboration, and empowers engineers to deliver reliable energy solutions worldwide. Watch the showcase here.

"The Curious Developer" continued

KDAB has released two new episodes as part of “The Curious Developer”, featuring in-depth conversations with experts from the C++ community. 

In the first interview, Jesper talks with Nicole Patricia Mazzuca about the world of C++ build tooling, covering real-world challenges with CMake and other systems, insights from vcpkg, and how new approaches like Rho - a new CMake library.

The second episode features Anders Schau Knatten, who discusses the origins of his C++ quizzes, the value of understanding low-level concepts, and how curiosity-driven exploration helps developers navigate undefined behavior and complex language details. 

Both videos are available to watch on YouTube or check out the entire playlist.
