Are you a student and wanted to know How and why overloading, templates, and auto deduction WERE invented? read the following article.
How and why overloading, templates, and auto deduction invented?
by Milad Kahsari
From the article:
Why we need the template function/classes and how this concept created by C++ compiler engineers? In this medium post, I want to go through the steps which made c++ experts think about the template concept and auto in the modern days of software development.

A good summary.
C++ - Initialization of Static Variables
by Pablo Arias
From the article:
You are probably reading this because you code in C++. This means that you have battled frustration mastering auto deduction rules or lost your sanity trying to understand why std::initializer_list was considered a good idea. Anyone who has been doing this long enough knows that variable initialization is everything but trivial. It’s a problem too essential to ignore but too challenging to master. Today I’m here to tell you that there is more to it...

New C and C++ meetup in Madrid. Thursday the 30th at Liferay's HQ.
How to accelerate a website with C++ and WebAssembly (Spanish)
with Juan Morales and Miguel Cantón
In order to reduce latency, costs and gain scalability we decided to perform data analysis with Graphext using WebAssembly in the browser. We will talk about how to use emscripten to compile a C++ project to make it portable on all browsers.

2 Lines Of Code and 3 C++17 Features - The overload Pattern
by Bartlomiej Filipek
From the article:
While I was doing research for my book and blog posts about C++17 several times I stumbled upon this pattern for visitation of std::variant:
template<class... Ts> struct overload : Ts... { using Ts::operator()...; }; template<class... Ts> overload(Ts...) -> overload<Ts...>;With the above pattern, you can provide separate lambdas “in-place” for visitation.
It’s just two lines of compact C++ code, but it packs a few interesting concepts.
Let’s see how this thing works and go through the three new C++17 features that make this patter possible...

Did you know about the proposal?
Why were abbrev. lambdas rejected?
by Barry Revzin
From the article:
In November, 2017, I presented my proposal for abbreviated lambdas (P0573R2) to Evolution in Albuquerque. It was rejected (6-17), though the group was willing to consider future proposals for shorter lambdas which present new technical information (18-2).
Since then, there’s been a lot of confusion about what actually happened and why it was rejected, and part of this was my fault for not doing a good job communicating this to interested parties. Actually, that’s generous - I didn’t really communicate anything. So here is my making up for lost time by actually conveying this information...

C++20: Concepts - Predefined Concepts
by Rainer Grimm
From the article:
C++20 has many predefined concepts. Consequentially, before you define your concept, you should know the existing ones. This post gives you an overview of the predefined concepts. To get the general idea of concepts, read my previous posts...
