Do you use them badly?
Smelly std::pair and std::tuple
by Arne Mertz
From the article:
Depending on their use,
std::pairandstd::tuplecan be code smells. That’s why we should be careful around these two.Having a code smell is not a no-go, it’s more like a red flag. It’s one of those things that are not a problem themselves but rather a hint that there might be a less obvious problem hidden in the code.

C++ for embedded too!
Making things do stuff – Part 1
by Glennan Carnie
From the article:
C has long been the language of choice for smaller, microcontroller-based embedded systems; particularly for close-to-the-metal hardware manipulation.C++ was originally conceived with a bias towards systems programming; performance and efficiency being key design highlights. Traditionally, many of the advancements in compiler technology, optimisation, etc., had centred around generating code for PC-like platforms (Linux, Windows, etc). In the last few years C++ compiler support for microcontroller targets has advanced dramatically, to the point where Modern C++ is a increasingly attractive language for embedded systems development...

Variadic CRTP
by Steve Dewhurst
From article:
One problem with [the] traditional application of CRTP is that it’s inflexible.... We can get [more] flexibility by specifying the CRTP capability as a template template parameter.

A new trip report from the just-concluded ISO C++ meeting:
Trip report: C++ standards meeting in Kona, February 2017
by Botond Ballo
From the article:
ConclusionC++17 is effectively out the door, with its Draft International Standard sent out for ballot, and the official release expected later this year.
Development on C++20 is well under way, with numerous core language and library features already earmarked for it, and several Technical Specifications expected to be merged into it. A proposal for an overall vision for the release aims to focus the committee’s efforts on four headliner features – Concepts, Modules, Ranges, and Networking. That is, of course, not a guarantee these features will be in C++20 (nor is it intended to exclude other features!), but I believe with some luck and continued hard work we can make part of all of that plan a reality.Modules, in particular, are expected to be a game-changer for C++...

A trip report from the just-concluded ISO C++ meeting:
Trip report: Winter ISO C++ standards meeting (Kona), C++17 is complete
by Herb Sutter
From the article:
C++17 is done!
The big news is that we completed C++17, which dominated the work of the meeting: C++17 is now technically finished and being sent out for its final ISO balloting. All that remains for C++17 now is some ISO red tape and minor touch-up to get it officially published, which is expected to be just mechanical...

constexpr evolves!
Constexpr Additions in C++17
by Arne Mertz
From the article:
Last year, I have written about constexpr and compile time constants in general. Last week, the Draft International Standard for C++17 has been sent to its ballot. Time to provide some updates to earlier posts!

What do you think?
Does const mean thread-safe?
by Anthony Williams
From the article:
There was a discussion recently on the cpplang slack about whether const meant thread-safe.
As with everything in life, it depends. In some ways, yes it does. In others, it does not. Read on for the details.

The use of Singleton is often justified by the will of being able to easily refer to a unique object from any point. Giuseppe Puoti describes an alternative:
Singleton revisited

From the article:
It happens quite often to deal with those annoying objects, used everywhere in your applications. This may be because of a poorly designed application but, sometime, it is simply an inevitable condition...

Do you use it?
C++ Braced Initialization
by Edouard of quasardb
From the article:
Since C++ 11 it's possible to use braces for construction and initialization. Although this is something you could ignore for the code you write, it's obviously important to know for the code you may read.
If you have a couple of years of experience in C++, the temptation can be great to keep your old habits because "All these new features are useless! The language is bloated! Those people in the committee!".
Let's make sense out of the bloat...
