Maybe the title is a bit clickbaity — sorry for that. But I’ve seen many people unintentionally introduce undefined behaviour (UB) into their code through Boost unit tests. Sure, it’s “only” in the...

Last week, we discussed how to write our own formatter and finished with a relatively simple solution for printing a struct called ProgrammingLanguage. Today, we’ll take it to the next level. Add ...

I recently published two posts about how C++26 improves std::format and the related facilities. (If you missed them, here are Part 1 and Part 2). Now it’s time to explore how you can format your ow...

In Part 1, we explored the improvements C++26 brings to std::format — from better to_string behavior to compile-time safety checks. In this part, we look at runtime formatting, defect fixes, and su...

C++26 brings a series of improvements to std::format, continuing the work started in C++20 and refined in C++23. These changes improve formatting consistency, runtime safety, and user ergonomics. T...

Another year, another trip report from C++ On Sea! First, a heartfelt thank-you to the organizers for inviting me to speak, and an equally big thank-you to my wife for taking care of the kids whil...

I wrote a couple of times about dynamic_cast and I discouraged you from using it. In general, it makes code worse in terms of readability. When you get rid of dynamic_cast, either via self-discipli...

Let’s talk about class templates and variadic parameters. How to use them in combination? But first of all, what are variadic templates? Variadic template don’t accept a fixed size of parameters,...

In short, thanks to P2748R5 by Brian Bi, it’s no longer possible to return a reference that binds to a temporary expression, and that’s just lovely. What exactly is changing? Often, a proposal mo...

Let’s talk about getting into conferences. I’ve already shared my path into conference speaking, and more recently, Andre Schau Knatten wrote about how to become a conference speaker. As the ques...
