Welcome to our July 2024 Newsletter

Quite a bit has happened since you received our June newsletter!

We have two new blogs introducing two of our best practices guides, The Smarter Way to Rust and Behind the Scenes of Embedded Updates, and we've also published two of our regularly scheduled blogs, Using Nix as a Yocto Alternative and Formatting Selected Text in QML. 

If you enjoy watching videos, you may want to take a look at our YouTube channel, where we've added two new videos, including a short about improving qDebug print out. Raise your glasses, because this video short is the 100th of Jesper Pedersen's Qt Widgets and More videos! We also released our next, full-length Qt Widgets and More video in the series, this one being about Signal Throttlers.

You have several upcoming trainings to choose from, as well as a few events where we hope you'll come find us. FlutterCon has come and gone and the schedule for KDE Akademy is now available. Watch our FlutterCon recap to see how it went. In other exciting news, the call for papers for Qt World Summit 2025 is now underway.

The Smarter Way to Rust

by Andrew Hayzen and Leon Matthes

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. This blog delves into some key concepts for integrating Rust and C++.

Behind the Scenes of Embedded Updates

by Andreas Holzammer 

We’ve talked about some of the key structural elements that go into an embedded OTA architecture. But what about the back end? We'll introduce you to considerations for the back end in this blog.

Using Nix as a Yocto Alternative

Building a bootable Linux image from the ground up in a declarative way

by Magnus Groß

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. Take a look at Nix as an alternative to Yocto and buildroot, in this blog.

Formatting Selected Text in QML

Quasi-Backporting Qt 6.7 QML cursorSelection to Older Versions

by Matt Aber 

A guide to backporting features, implementing attached properties, and doing more sane text editing in QML apps -- which is especially useful for implementing any kind of richtext editing in a QML application, where this functionality is severely lacking in any Qt version prior to 6.7.
