Parallel Algorithms of the STL with the GCC Compiler
by Rainer Grimm
From the article:
GCC supports my favorite C++17 feature: the parallel algorithms of the Standard Template Library (STL). I recognized this a few days ago, and I'm happy to write a post about it and share my enthusiasm...

Software Architecture with C++, Book Review
by Bartlomiej Filipek
From the article:
In April, we got a new book - from two Polish authors - Piotr and Adrian - on C++ Software Architecture. This one is fascinating and refreshing. While it won’t teach you all the latest C++ features or low-level tricks in our favorite language, it will move you to a higher level with architecture, building, patterns, design, and development for the cloud.
Let’s see what’s inside.

Registration is now open for CppCon 2021, which starts on October 24 and will be held both in person and online. To whet your appetite for this year’s conference, we’re posting videos of some of the top-rated talks from our most recent in-person conference in 2019 and our online conference in 2020. Here’s another CppCon talk video we hope you will enjoy – and why not register today for CppCon 2021 to attend in person, online, or both!
How to Herd 1,000 Libraries
by Robert Schumacher
Summary of the talk:
In the current C++ world, it is a struggle to convince even a single external library to build and behave. Adding a third and fourth dependency causes quadratic grief as each library interacts with each other and One Definition Rule violations lurk around every corner.
How, then, is it possible to manage over 1,000?
In this talk, we'll talk about the techniques, shims, and hacks used in the Vcpkg package manager to persuade, connive, and coerce all these independent moving parts into a single robust ecosystem. We'll sample the myriad approaches used by real-world libraries to declare dependence and walk through how they can be guided to do the right thing at the end of the day.
Private package management systems still thrive in corporations and these approaches can provide method to the madness of consuming open source.

Variable Templates
by Barbara Geller and Ansel Sermersheim
About the video:
We found a great place to use a variable template that is not simply the math constant PI. In this video, we showcase roughly 15 lines of code that uses method pointers, template argument deduction, overload resolution, parameter packs, function objects, and a variable template. This video answers the question "so, what are variable templates good for?"

C++ Trainings at Meeting C++ 2021
by Jens Weller
From the article:
Today I can give you a first overview on the planned trainings that accompany Meeting C++ 2021. All trainings are held online, the date is chosen by the trainers.
This years Meeting C++ conference focuses on learning and giving you the best experience online. Meeting C++ has chosen some of the best trainers to give you an opportunity to learn even more about C++ in 2021. Rainer Grimm, Patricia Aas and Slobodan Dmitrovic are the trainers for the first 3 fantastic courses.

Breaking Dependencies: The SOLID Principles
by Klaus Iglberger
Summary of the talk:
SOLID is an abbreviation for five of the most important software design principles:
- (S)ingle Responsibility Principle
- (O)pen-Closed Principle
- (L)iskov Substitution Principle
- (I)nterface Segregation Principle
- (D)ependency Inversion PrincipleFor almost two decades, these principles have proven to be a valuable set of guidelines to cope with software dependencies. Although initially introduced as guidelines for object-oriented programming, they have become a universal set of guidelines that can be used equally well for procedural, functional or generic programming. In this talk I'll recap the SOLID principles and explain why they form such a valuable set of universal design guidelines. Also, I'll go into detail about several common misconceptions.

Announcing CppCon Academy 2021 Classes
by Jon Kalb
From the article:
Registration is open for almost twenty CppCon Academy classes that will be held in the days before or after CppCon 2021 in October.
Four classes are open to online attendees and the rest will be offered to onsite attendees at the Gaylord Rockies in Aurora.
This year we are offering classes that range from those that are focused on updating you to the latest versions of C++, to those focusing on better code, testing, or design skills. This year we are offering a class on computing in mixed CPU/GPU/FPGA environments and two on embedded programming. ...

Extended Aggregate Initialisation in C++17
by Jonathan Boccara
From the article:
By upgrading a compiler to C++17, a certain piece of code that looked reasonable stopped compiling.
This code doesn’t use any deprecated feature such as std::auto_ptr or std::bind1st that were removed in C++ 17, but it stopped compiling nonetheless.
Understanding this compile error will let us better understand a new feature of C++17: extended aggregate initialisation...

C++20 three way comparison operator — ensure backward compatibility: Part 8
by Gajendra Gulgulia
From the article:
In part one till seven of the tutorial series, we looked at how to use the C++20’s three way comparison operator. In this part of the tutorial series, we’ll look at the compatibility issues when using objects that were constructed before C++20 with the three way comparison operator and how to resolve them...

Reducing Template Compilation Overhead, Using C++11, 14, 17, and 20
by Jorg Brown
Summary of the talk:
At their best, new C++ standards offer simpler, clearer, and faster-to-compile ways to write your code. But many information sources, for example Andrei Alexandrescu’s Modern C++ Design, haven’t been updated.
More importantly, template metaprogramming is not something we generally seek to optimize because a good compiler handles it well, and problems generally only show up in the form of long compile times.
In this presentation, I'll describe techniques you can use to simplify, clarify, and improve the compile speed, of your code, including:
* Using C++17 "if constexpr"
* Using C++11 variadic function / template arguments (often without needing recursion!)
* Using decltype on auto-return functions in order to compute types in a more readable way.
* Using C++20 constraints rather than std::enable_if
