PayloadOffset_t: A small type design challenge
Recently, I had to make a relatively small design decision – which type to use for a small range of values. As usual in C++, there were a number of […]

Language and library features
Core Guidelines are not Rules
There is a difference between guidelines and rules. Boiling down guidelines to one-sentence rules has drawbacks that make your code harder to understand.
isValid()? Establish invariants and avoid zombie objects
When classes have an “isValid” method or similar, the code using them often is less clear and harder to maintain. If possible, validity should be an invariant that can not […]
Docker4c: portable C++ development environment
Installing everything we need to develop C++ applications can be a lengthy, even painful process. Docker makes it possible to build a development environment once and deploy it everywhere. The […]
Colony – A brief history of timing
In another guest post, Matt Bentley provides us with new insights into container performance, analyzing the implications on iteration costs of his implementation of the “bucket array” concept.
Constexpr FizzBuzz – An Exercise in Compile-Time Calculations
Recently, I have given a workshop about language features introduced in C++14 and C++17. Since a major part of those features includes constexpr things, I gave my trainees the task […]
plf::list and the Disassembly of Time Complexity
In his third guest post, Matt Bentley shows us the impact of cache-locality on performance, using plf::list, his implementation of a cache-local linked list as example.
Multiple dispatch over covariant functions
Today we have another guest post by Alfredo Correa. In his previous article, Functions of variants are covariant, Alfredo described the concept of a covariant function, that is, how a […]
algorithms and the KISS principle
You’ve probably heard about the rule to prefer standard algorithms over raw for loops. The major reason is that those algorithms say what is happening in the name and encapsulate […]
Macro Evil in C++ Code
Today, I am happy to announce a guest post by Andrey Karpov about the evil of macros. Andrey is a Microsoft MVP in the “Developer Technologies” category and one of […]
