From the article:
In the previous blog post I shared how template specialization and template instantiation are processed in the MSVC compiler. We will now look at some examples from real-world code bases to show some ways to reduce the number of them...

Optimise templates.
Build Throughput Series: Template Metaprogramming Fundamentals
by Xiang Fan
From the article:
Template metaprogramming is popular and seen in many code bases. However, it often contributes to long compile times. When investigating build throughput improvement opportunities in large codebases, our finding is that more than one million template specializations and template instantiations is quite common and often provides optimization opportunities for significant improvement.
In this blog post, I will walk through the differences between template specialization and template instantiation and how they are processed in the MSVC compiler...
4 Features of Boost HOF That Will Make Your Code Simpler--Jonathan Boccara

4 Features of Boost HOF That Will Make Your Code Simpler
by Jonathan Boccara
From the article:
Boost HOF, standing for Higher Order Functions, is a Boost library offering functions that work on functions.
This impressive library provides a lot of advanced components allowing to go a step further into functional programming in C++. In this post, we’ll focus on 4 of the more basic ones (+ a bonus one) that allow to make code simpler in common tasks.
HOF provides one header in the form of #include <boost/hof/XXX.hpp> for each component, as well as a general header #include <boost/hof.hpp>. It is compatible with C++11...
