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.

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
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.

Making things do stuff – Part 9
by Glennan Carnie
From the article:
As a final instalment in this series on hardware manipulation I thought I’d revisit read-only and write-only register types.

Another new feature.
C++17: Nested Namespaces
by Marc Gregoire
From the article:
The second post in this series of C++17 features highlights a tiny but very useful new feature called nested namespaces.

In this article "No Bugs" Hare outlines the possibility to run C++ code in the major four web browsers.
(Not Really So) New Niche for C++: Browser!?
by "No Bugs" Hare
From the article:
For quite a long while, C++ had been losing popularity; for example, as reported in [Widman16], in 2016 it got 7% less of the listings on Dice.com compared with a year earlier; and according to [TIOBE17], from the C++ Golden Age in 2004 till 2017, the C++ share fell from ~17% to a measly 6%.
As all of us (as in, ‘hardcore C++ fans’) know , this has nothing to do with the deficiencies of C++; rather it is related to an observation that the time of downloadable clients (which was one of the main C++ strongholds) has changed into the time of browser-based clients – and all the attempts to get C++ onto browsers were sooo ugly (ActiveX, anyone?) that this didn’t really leave a chance to use C++ there.
Well, it seems that this tendency is already in the process of being reverted:
C++ can already run on all four major browsers – and moreover, it has several all-important advantages over JavaScript, too.
And this – not too surprisingly – is what this article is all about.

It is coming!
C++17: Structured Bindings
by Marc Gregoire
From the article:
This is a first post in a series of short articles on new C++17 features. These articles will not contain all little details of the new features being presented, but they give you an idea about what new functionality has been added to C++17.

The series continue.
C++17 in details: Code Simplification
by Bartlomiej Filipek
From the article:
You might say that most of the new language features (not to mention The Standard Library improvements) are there to write simpler/cleaner code. The “C++17 in details” series reviews most of the bigger things, still for today, I tried to pick a few features that out of the box make your code more compact.
- Structured bindings/Decomposition declarations
- Init-statement for if/switch
- Inline variables
- constexpr if (again!)
- a few other mentions

Quick A: Use is_detected
Recently on SO:
How to require an exact function signature in the detection idiom?
With C++17
is_detected, you may dotemplate <typename T, typename Ret, typename Index> using subscript_t = std::integral_constant<Ret (T::*) (Index), & T::operator[]>; template <typename T, typename Ret, typename Index> using has_subscript = is_detected<subscript_t, T, Ret, Index>; static_assert(has_subscript<std::vector<int>, int&, std::size_t>::value, "!"); static_assert(!has_subscript<std::vector<int>, int&, int>::value, "!");

Metaclasses: Thoughts on generative C++
by Herb Sutter
From the article:
I’ve been working on an experimental new C++ language feature tentatively called “metaclasses” that aims to make C++ programming both more powerful and simpler. You can find out about it here...

Do you know these new attributes?
C++17 attributes - maybe_unused, fallthrough and nodiscard
by Simon Brand
From the article:
C++17 adds three new attributes for programmers to better express their intent to the compiler and readers of the code: maybe_unused, fallthrough, and nodiscard. This is a quick post to outline what they do and why they are useful.
