Two new things for the C++ community: a review community and Meeting C++ certified libraries
A C++ review community
by Jens Weller
From the article:
I've been thinking about this for a while, and for now its:
- a C++ community focused on reviewing libraries: r/cpp_review
- a by Meeting C++ provided and supported certification of libraries + a listing of these.

Yes there is one.
The real difference between struct and class
by Jonathan Boccara
From the article:
“Should I use a struct or a class?”
Such is the question many C++ programmers ask themselves, or ask around to more experienced co-workers, when designing their code.

It had to be done - Abusing co_await for optionals
by redditsoaddicting
From the article:
I finally got around to playing with coroutines in the context of non-future types. I always guessed this could be done. For optionals specifically, the idea is that you do auto x = co_await foo(); and either x is the value in the optional or the function immediately returns an empty optional...

A first list on confirmed speakers and their talks for this years Meeting C++ conference!
Confirmed Speakers & Talks at Meeting C++ 2017
by Jens Weller
From the article:
Last week the decisions for who could speak at Meeting C++ 2017 was made, and the selected candidates were contacted. Here is a little overview on talks and speakers for this years conference. There is a few speakers which haven't reacted yet, hope to share these talks soon too.

Making things do stuff
by Glennan Carnie
From the article:
As code designers we tend to eschew specific ‘stove-pipe’ code in favour of reusable code elements. Up until now we’ve been coding some very specific examples so it’s probably worth looking at some more generic solutions...

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:
Improving Performance Through Compiler Switches...
by Tim Haines
Summary of the talk:
Much attention has been given to what modern optimizing compilers can do with your code, but little is ever said as to how to make the compiler invoke these optimizations. Of course, the answer is compiler switches! But which ones are needed to generate the best code? How many switches does it take to get the best performance? How do different compilers compare when using the same set of switches? I explore all of these questions and more to shed light on the interplay between C++ compilers and modern hardware drawing on my work in high performance scientific computing.
Enabling modern optimizing compilers to exploit current-generation processor features is critical to success in this field. Yet, modernizing aging codebases to utilize these processor features is a daunting task that often results in non-portable code. Rather than relying on hand-tuned optimizations, I explore the ability of today's compilers to breathe new life into old code. In particular, I examine how industry-standard compilers like those from gcc, clang, and Intel perform when compiling operations common to scientific computing without any modifications to the source code. Specifically, I look at streaming data manipulations, reduction operations, compute-intensive loops, and selective array operations. By comparing the quality of the code generated and time to solution from these compilers with various optimization settings for several different C++ implementations, I am able to quantify the utility of each compiler switch in handling varying degrees of abstractions in C++ code. Finally, I measure the effects of these compiler settings on the up-and-coming industrial benchmark High Performance Conjugate Gradient that focuses more on the effects of the memory subsystem than current benchmarks like the traditional High Performance LinPACK suite.

Complete set up of a project:
Modern C++ CI
by Juan Medina
From the article:
Modern C++ is great, some people are even calling it a new language, but is not only the language what is evolving the tool-chain is getter better, so doing continuous integration for cross platform projects is simple and effective.
I decide to do a simple project using some of the C++14 features and following the C++ Core Guidelines whenever its possible. The result is available in this repository.
