Quickselect is a selection algorithm to find the `k'th` smallest element in an unordered list. It is closely related to the Quicksort sorting algorithm. Like Quicksort, it is efficient traditionally and offers good average-case performance, but has a poor…

Introduction Profiling, debugging, and investigating C++ applications doesn't have to be insanely hard. If you have been a C++ developer for many years, you might be used to memory tracing tools like Valgrind -- with a potential 10x overhead), instrumentation…

The problem C/C++ libraries expect to be able to change the internal implementation details of opaque data types from release to release since such a change has no external ABI consequences

Since C++ 11 it's possible to use braces for construction and initialization. Although this is something you could ignore for the code you write, it's obviously important to know for the code you may read. If you have a couple of years of experience in C++…

In the post How to Train Neural Networks With Backpropagation I said that you could also calculate the gradient of a neural network by using dual numbers or finite differences. By special request, …

Better compiler support for C++11 enable tighter QStringLiteral guarantees: From Qt 5.9 on, it never allocates memory, and references into it never expire.

Let's see how structured binding introduced in C++17 will change the way to interact with std::pair, std::tuple, std::array and such: ...

I'm using an SDK for an embedded project. In this source code I found some code which at least I found peculiar. In many places in the SDK there is source code in this format:

Two months back, we went over the process of building a DSL for arithmetic operations and we introduced the concept of Catamorphism as a way to decouple the traversal of an AST from the operations …
