The Reset trick My last month's post, Singleton done right in C++, has triggered plenty of comments. I expected a few, but not that much. So thank you...

In my latest blog post, "The Reset trick," you'll learn why I used to make the copy- and move-operations private and default last time.

Efficient C++: The hidden compile-time cost of auto return types In today's post, I would like to dive into writing efficient C++ code. As you probably know, one post will not cover this entire topic....

Check out my post, "Efficient C++: The hidden compile-time cost of auto return types," you'll learn how to optimize compile times for your C++ code.

Singleton done right in C++ In today's post, I like to touch on a controversial topic: singletons. While I think it is best to have a codebase without singletons,...

a screenshot of an editor showing a snippet of code that defines an interface, and a type that models the interface non-intrusively, and a type named `any` that is parameterized on the interface and that stores the model while erasing its type.

No Advent of Code for me. Instead, I've used the break to write the type-erasure library I have always wanted.

C++ doesn't make it easy to have both dynamic polymorphism *and* value semantics, but this little utility does!

Interfaces can extend other interfaces, and it works in consteval, too. 🤩
