At this year’s Qt World Summit, Qt celebrated its 30th birthday. A lot has happened over those 30 years — including plenty you’ve probably never heard of... Like the time Trolltech (the original Qt company) used up a large portion of Norway’s internet, the reasoning behind Trolltech needing an office in Australia so early on, and much, much more. In this episode, Jesper talks with Troll #4 (now the most senior Troll — by far) for a walk down memory lane. You won’t learn about new graphics APIs or how to use coroutines with Qt, but hopefully, it will give you a good laugh. So grab a cup of your favorite beverage and enjoy.

Clang-tidy is a static analysis tool for C/C++ code, warning its users about potential errors, performance problems or code that modern C++ allows to express in a better way. Often, clang-tidy can even apply modernizations automatically. Applying clang-tidy is not exactly intuitive, but successfully applied, it is an invaluable support in migrating large codebases to new C++ standards.

C++ Applications Architecture Best Practices: Migrating to New C++ Standards with Clang-tidy

Clang-tidy is a static analysis tool for C/C++ code, warning its users about potential errors, performance problems or code that modern C++ allows to express in a better way. Often, clang-tidy can even apply modernizations automatically. Applying clang-tidy is not exactly intuitive, but successfully applied, it is an invaluable support in migrating large codebases to new C++ standards.

Introduction to Qt Widgets (Part 59) - Tree Models

When you implement a model, it is worthwhile remembering that one day an intern, with far less experience than you, might implement a proxy model which sits on top of your model and acts as the view. This proxy model might be broken in ways you couldn't even imagine, so better check that the index provided are actually referring to valid data in your model. This episode discusses this in details, and offers you a simple library with all checks needed.
