How I used Huffman coding to easily create a translator into a fictional language
With modern computers, creating a language doesn’t have to be time-consuming. Actually, far less time-consuming than learning a language.

You can define template methods in .cpp files without explicit instantiation, as long as they are private
For years I’ve been programming in C++ with the belief that the bodies of template methods had to be in headers. Only recently I learned that splitting template methods between header and source is, in fact, often perfectly fine.
Stop telling C/C++. There is C and then there is C++.
Ever been criticised for using totally working C code in a C++ codebase just because it wasn’t proper C++? Here’s why you shouldn’t have done it.
Adding elements to arrays and changing variables during compilation – imperative meta-metaprogramming in C++
If you follow these steps, you might learn to write things normally impossible to do in compile time, such as self-registering factory.
C++20 Resumable functions: Goodbye state machines, no one will mourn you
C++20 allows writing functions that suspend and can continue at the next line. This has an amazing application at avoiding writing annoying and error-prone state machines. This article showcases how coroutines can clean up a function that would usually need an ugly state machine.
The Sisyphean task of enabling Adobe Flash Player in a modern QT/Chromium based web browser
Prologue and motivation A part of my PhD. research deals with computer science as a source of innovative ways to…
Adding OpenCV libraries to a QT5 project in Ubuntu 20.04
I’ve recently gained interest in OpenCV. The problem with this is, that in most modern tutorials and walkthroughs it seems…
Using vectors in place of hashtables – not as dumb as it seems
Vector can find elements in linear time, hashtable in constant time. That’s a pretty elementary part of computer science. However, better complexity does not always mean it’s faster.
Super compact serialisation of C++ classes
How about defining the variable, initialising it and writing code for serialisation and deserialisation on a single line of code?
Generic self-registering factory – no more need to write factories
It’s somewhat annoying that a factory needs to depend on all classes that inherit from the common interface. This issue can be avoided using a self-registering factory.
