It's getting closer.

Qt talks at CppCon 2017

by Giuseppe D'Angelo

From the article:

The program for CppCon 2017 is now published!

CppCon is the annual conference for the C++ community: five days packed with over 100 talks, as well as inspiring keynotes, panel discussions, hallway chats, fun evening events and much more. CppCon is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer community and promote the understanding and use of modern, standard C++ on all compilers and platforms.

A revolution!

A Summary of the Metaclasses Proposal for C++

by Jonathan Boccara

From the article:

A couple of weeks ago, Herb Sutter posted his proposal about metaclasses, triggering a wave of enthusiasm among the C++ community. And for good reason.

CppCon 2016: The Blaze High Performance Math Library--Klaus Iglberger

By Adrien Hamelin | Aug 7, 2017 03:24 PM | Tags: performance community

Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:

The Blaze High Performance Math Library

by Klaus Iglberger

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

In this presentation we introduce the Blaze C++ math library, a hot contender for the linear algebra performance throne. Blaze is an open-source, high-performance library for dense and sparse arithmetic. It combines elegance and ease of use with HPC-grade performance, making it one of the most intuitive and at the same time fastest C++ math libraries available.

We demonstrate its basic linear algebra functionality by means of several BLAS level 1 to 3 operations and explain why Blaze outperforms even well established linear algebra libraries. Additionally, we present some advanced features that enable users to adapt Blaze to special circumstances: custom data structures, custom operations, and the customizable error reporting mechanism.

C++ Weekly Episode 75: Why You Cannot Move From Const—Jason Turner

Episode 75 of C++ Weekly.

Why You Cannot Move From Const

by Jason Turner

About the show:

You may have noticed that it's possible to use std::move with a const object, but have you stopped to consider what it does? What you think is a move is silently reverting to a copy without your knowing. In this episode Jason explains what is happening and why.

Trip Report: C++ Standards Meeting in Toronto, July 2017

by Botond Ballo

From the article:

A couple of weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Toronto, Canada (which, incidentally, is where I’m based). This was the second committee meeting in 2017; you can find my reports on previous meetings here (November 2016, Issaquah) and here (February 2017, Kona). These reports, particularly the Kona one, provide useful context for this post.

CppCon 2016: Implementing `static` control flow in C++14--Vittorio Romeo

Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:

Implementing `static` control flow in C++14

by Vittorio Romeo

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

There has always been great interest in imperative compile-time control flow: as an example, consider all the existing `static_if` proposals and the recently accepted `constexpr_if` construct for C++17.

What if you were told that it is actually possible to implement imperative control flow in C++14?

In this tutorial, the implementation and design of a compile-time `static_if` branching construct and of a compile-time `static_for` iteration construct will be shown and analyzed. These constructs will then be compared to traditional solutions and upcoming C++17 features, examining advantages and drawbacks.
