A real-time Python tool for solving logic games (like Sudoku) with OpenCV, a backtracking algorithm and… a pinch of Deep Learning. — I like logic games. I like also Computer Vision and Artificial Intelligence algorithms. To combine the two things, I built a software that detects, analyzes and solves some logic puzzles like Sudoku and Skyscrapers. In this article I will explain the project “LogicGamesSolver”. …

Use const, enum and inline instead — Item 2: Prefer consts, enums, and inlines to #defines. Effective C++, Scott Meyers, 2005. Take this simple example: #define PI 3.14159 A simple #define for representing the constant PI. Well, the problem here is that the compiler may not even be aware that we have defined this constant. This is…

To make sense of C++, think of it as a merging of more sublanguages — Item 1: View C++ as a federation of languages. Effective C++, Scott Meyers, 2005. C++ is a rich programming language. It supports various programming styles and language features. Unfortunately, this abundance can be daunting in its sheer size. …

Key Concepts to Become an Effective C++ Developer — Learning the fundamentals of a programming language is one thing; learning how to design and implement effective programs in that language is something else entirely. This is especially true of C++, a language boasting an uncommon range of power and expressiveness. SCOTT D. MEYERS, Effective C++, 2005 C++ is a…

It looks like black magic, but it’s just an optimization technique — There is a part of C++ developers that appreciate template metaprogramming. And there are all the other C++ developers. Jonathan Boccara, Expressive C++ Template Metaprogramming C++ Template Metaprogramming is a powerful feature often not known even by senior developers. …

Complete explanation, usages and drawbacks — Historically memory management has been a significant challenge for C++ developers. This is because C++ is a low-level language that provides direct access to memory, which gives developers great flexibility and control but also requires them to manage memory manually. …

KISS, DRY, YAGNI, SOLID, LSP, POLA and friends — Every developer interested in improving the quality of the code they produce has heard of the concepts expressed in “Clean Code: A Handbook of Agile Software Craftsmanship” by Robert C. Martin and in other software engineering masterpieces. Principles such as KISS, YAGNI, DRY and SOLID are now thankfully known by…

And why you should learn it — Like any C++ programmer, I spend at least half my time dealing with (and worrying about) memory management issues. Although great strides have been made since C++11 (just think of smart pointers or the RAII principle), most C++ developers, even the most experienced ones, have to surrender to the idea…

The differences between the Stack and the Heap and why they are still important to understand — Memory management in C++ is really powerful for optimizing performance, especially for large and distributed software. Unlike some other languages like Java, C++ does not have an automatic garbage collector that automatically manages memory for the programmer. This can be seen as a disadvantage, as it requires the programmer to…
