Italian C++ Conference 2019: Call for sessions and sponsors
I am very happy to announce the 4th edition of the Italian C++ Conference, the biggest annual conference about C++ development in Italy.
When: June 15, 2019
Where: Milan (Politecnico di Milano)
Website: https://italiancpp.org/itcppcon19
I am very excited to have Andrei Alexandrescu as keynote speaker this year!
The call for sessions is open until Feb 28:
One track will be entirely in English.
The event is totally not-for-profit so we are looking for sponsors. For more information, please get in touch by sending an email to info [at] italiancpp [dot] org.

Variant Visitation V2--Michael Park
Optimising accesses.
Variant Visitation V2
by Michael Park
From the article:
In 2015, I wrote an article titled Variant Visitation which described an implementation strategy for std::visit. The approach involved a matrix of function pointers, and many have raised concerns regarding poor code-gen caused by optimization limitations of function pointers on some compilers.
This post describes the switch-based approach implemented in mpark/variant, and its benchmark results...
C++ moves for people who don’t know or care what rvalues are--Topher Winward
Is it simpler that way?
C++ moves for people who don’t know or care what rvalues are
by Topher Winward
From the article:
When I was first learning about move semantics in C++, I kept reading articles that explained in terms of other scary sounding jargon — lvalues, rvalue references, memcpy, ownership. None of these things are strictly necessary to know about to understand the core of move semantics. (Though, the more you learn about them, the greater your understanding of move semantics will become.)
You may have heard of move semantics, and may know that they’re “faster”, but not why, or even how to move something. (Here “moves” and “move semantics” mean the same thing.)
This article will deliberately simplify or ignore some concepts (like constructors, rvalue references, stack vs heap) to make the core idea of moving easier to follow, so don’t worry if you already know this stuff and see something that isn’t technically correct. I’ll mark clarifications for these with a number. This article is aimed at those writing everyday (non-library) code, with little to no existing understanding of move semantics, to help get over the initial conceptual hurdle...
