Template Instantiation
by Rainer Grimm
From the article:
Template instantiation is the creation of a concrete function or a concrete class out of a function template or class template. The creation of template instantiation can be implicit (compiler-generated) or explicit (user-provided)...

Adding a book section to Meeting C++
by Jens Weller
From the article:
The section offers a listing of current C++ books, currently 14 books by various authors such as Bjarne Stroustrup or Rainer Grimm! More books will be listed in the future, as not all authors had yet time to list their books. July/August is a holiday month after all, though that might give you the time to read a book!

Counting in Iteration Models
by Barry Revzin
From the article:
There’s a really interesting issue pointed out in the July 2021 mailing by way of P2406R0.
Basically, in C++, the iterator loop structure ordering is as follows (I wrote it with a goto to make the ordering more obvious. Note that in C++, we start with the it != end check, not the ++it operation. The point of this ordering is to focus on the transition from one position to the next)...

C++20 concepts are structural: What, why, and how to change it?
by Jonathan Müller
From the article:
C++20 added concepts as a language feature. They’re often compared to Haskell’s type classes, Rust’s traits or Swift’s protocols.
Yet there is one feature that sets them apart: types model C++ concepts automatically. In Haskell, you need an instance, in Rust, you need an impl, and in Swift, you need an extension. But in C++? In C++, concepts are just fancy boolean predicates that check for well-formed syntax: every type that makes the syntax well-formed passes the predicate and thus models the concepts.
This was the correct choice, but is sometimes not what you want. Let’s explore it further.

Performance of the Parallel STL Algorithms
by Rainer Grimm
From the article:
I presented in my last post "Parallel Algorithms of the STL with the GCC Compiler" the necessary theory about the C++17 algorithm. Today, I make a performance test using the Microsoft compiler and the GCC compiler to answer the simple question: Does the execution policy pay off?

Every year we ask thousands of developers, with various backgrounds from all around the globe, dozens of questions, which we have localized into many different languages. We then clean, weigh, and process the data carefully, and validate it against other data sources. Our goal is to extract the key trends, which we will present through infographics to the public. This data is used across JetBrains to help our team make the right decisions on both global and product-levels. We are happy to share this data with the community so we can all thrive together!

C++ is awesome, here's why...
by Vinit Jogani
From the article:
C++ is, hands down, one of the most misunderstood languages in software developer pop culture today. People often compare it to C because it is a "low-level" language. Consequently, it has received a reputation of being an esoteric language that only the performance paranoid care about. This is far from true. I have been programming in C++ as my primary language for a while now and the developer experience is actually really good -- much better than I had imagined it would be.
In this article, I want to debunk some common myths about C++ that I heard before I started using it. Then, I want to talk about the actual superpowers that C++ provides you that most other languages do not...

Migrating VAST to C++20 - A Field Report
by Benno Evers
From the article:
Recently, the VAST developers had a reason to celebrate. No, not the latest release—finally all our supported platforms have a working C++20 compiler available. Given that VAST is still comparatively moderate in size at around 70,000 lines of code and already uses C++17 extensively, we did not expect too much hassle. So we seized the chance, rolled up our sleeves and started converting.
The process was indeed mostly painless, but some errors still had us stumped for a while. Below we describe our experiences, in the hopes that they might be useful to others who attempt the same.

Parallel Algorithms of the STL with the GCC Compiler

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.
