New video on the CopperSpice YouTube Channel:
Any Optional
by Barbara Geller and Ansel Sermersheim
About the video:
In this video, we discuss the std::any and std::optional classes, what they are, and how you might use them to write type safe code. We also talk about type safety in general, and how it relates to C++.
Please take a look and remember to subscribe!

C++17's new and handy new operator that supports overaligned objects!
New new() - The C++17's Alignment Parameter for Operator new()
by Bartlomiej Filipek
From the article:
The whole deal about the new functionality is that you can forgot about the limitation of over-aligned data. It lets you write regular modern C++ code without worrying about specialized allocators or raw memory handling functions like std::aligned_alloc() or _aligned_malloc().

Just announced at CppCon:
Open Sourcing MSVC's STL
From the announcement:
Today at CppCon 2019, we (the MSVC team) announced that we’re releasing our implementation of the C++ Standard Library (also known as the STL) as open source.
https://github.com/microsoft/STL is our new repository, containing all of our product source code, a new CMake build system, and a README with more information. As it explains, we’re still working on migrating to GitHub. While you can clone and build the code right now, there are several things we need to do (like adding our test suites) before we can begin reviewing pull requests.
Q&A
Q: Why are you doing this?
A: There are several reasons. ...

C++ Core Guidelines: Type Safety
by Rainer Grimm
From the article:
The C++ core guidelines support three profiles: type safety, bounds safety, and lifetime safety. Thanks to the guideline support library (GSL), you can check your code against these profiles. Today, I start with the profile type safety...

Back to Basics at CppCon 2019
by Arthur O’Dwyer
From the article:
Tomorrow I’ll be flying out to Denver, Colorado, for CppCon 2019. This will be my busiest CppCon yet! Besides giving my “STL From Scratch” weekend course for the third year in a row, this year I’m also the chair of CppCon’s new “Back to Basics” track...

Quick A: this is no longer an issue with C++17.
Recently on SO:
Undefined reference to static constexpr char[]
Add to your cpp file:
constexpr char foo::baz[];Reason: You have to provide the definition of the static member as well as the declaration. The declaration and the initializer go inside the class definition, but the member definition has to be separate.

Matthias Gehre’s trip report of the ISO C++ committee meeting in Cologne in 2019.
Trip Report: ISO C++ Meeting Cologne (2019)
by Matthias Gehre
From the trip report:
This is my trip report of the ISO C++ Meeting in Cologne – my first ISO C++ Meeting.
I will not so much focus on the big features that were approved for C++20 (there are better reports),
but more describe my personal experience. The report also contains discussions on
many lesser-known papers.

We’re in the final countdown to this year’s CppCon, which starts on September 16. To whet your appetite for this year’s conference, here’s another of the top-rated talks from last year. Enjoy – and register today for CppCon 2019!
Nano-coroutines to the Rescue! (Using Coroutines TS, of Course)
by G. Nishanov
Summary of the talk:
Are you doing memory lookups in a huge table?
Does your embarrassingly random access to your lookup tables lead to memory stalls?Fear no more!
We will explore techniques that allow us to do useful work while the prefetcher is busily working on bringing the requested cache lines from main memory, by utilizing nano-coroutines.
And the best part, nano-coroutines can be easily implemented using Coroutines TS that is already available in MSVC and Clang compilers. With a little bit of library support we can utilize the coroutines to extract intra-thread parallelism and quadruple the speed up your lookups.
