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

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...

Reusable HTTP(S) Connections

by Richard Hodges

From the article:

Something I am often asked by users of Boost Beast is how to code a client which effectively re-uses a pool of HTTP connections, in the same way a web browser does.

The premise is straightforward - if our client is going to be making multiple calls to a web server (or several of them) then it makes sense that once a connection has been used for one request, it is returned to a connection pool so that a subsequent request can make use of it...
