Some bits and stuff.
Bit Manipulation with C++20
By Rainer Grimm
From the article:
This post concludes my presentation of library features in C++20. Today I write about the class std::source_location and a few functions for bit manipulation...

Feature Testing with C++20
by Rainer Grimm
From the article:
When your program's compilation broke with a brand-new C++20 feature, you often end with a few questions: Did I something wrong? Did I found a compiler bug? Does my compiler not yet support this feature? Thanks to the feature testing in C++20, the last question is easy to answer...

Lambdas.
Under the Covers of C++ Lambdas: Captures, Captures, Captures
by Andreas Fertig
From the article:
Lambda Capturing syntax allows us to quickly “wrap” a variable from the outside scope and then use it in the lambda body. We also know that under the hood the compiler translates lambda into a closure type… but what happens to those captured variables? Are they translated to public data members or private? See the newest guest post from Andreas to understand this tricky problem...

Safe Comparisons of Integrals with C++20
by Rainer Grimm
From the article:
When you compare signed and unsigned integers, you may not get the result you expect. Thanks to the six std::cmp_* functions, there is a cure in C++20...

The current object (*this) capture in a lambda expression has gone through some changes since C++11.
Capture *this in lambda expression: Timeline of change
by Hitesh Kumar
From the article:
A lambda defined inside a non-static member function can directly access the members of the current object (or its copy) via an appropriate capture clause. But how the current object can be captured has gone through some changes since C++11.

In this paper, I am going to discuss how can we as the application or device driver developers take advantage of I/O prioritization in the Windows OS.
I/O Prioritization in Windows OS
by Milad Kahsari Alhadi
From the article:
I/O prioritization improves the responsiveness of the system without significantly decreasing the throughput of the system. Typically, any topic related to I/O and threads requires a good understanding of Windows synchronization because of that, I will try to discuss everything from the ground up.
In this paper, I am going to discuss how can we as the application or device driver developers take advantage of I/O prioritization in the Windows OS. Finally (in the next paper, I will discuss the I/O completion mechanism of Windows) which is a magical feature.

Have you ever wondered how many kinds of strings are available in C++?
How Many Strings Does C++ Have?
by Giovanni Dicanio
This blog post tries to enumerate some of them.
Now, let’s enter – drumroll, please – The Realm of C++! And the fun begins

This time around, I shall tell you about the royal game, i.e. chess, or rather of my humble attempts at contributing to its rich ecosystem of non-human players.
The Royal Game
by Philipp Lenk
From the article
I will begin by explaining what I am talking about, briefly recap the fascinating history of computer chess and in the course of that highlight the importance of game playing for showcasing, popularizing and driving machine intelligence research as well as its public perception. I shall further elaborate on my personal connection and love for the game and detail why - even in the face of a recent uptake of machine learning based techniques far more successful than my puny attempts could ever hope to be - an old-school, classical approach can still be a valuable investment of time and energy.
Afterwards [...] I will get just a little more technical and provide a high level explanation of the general structure underlying many chess playing programs, culminating in a walkthrough of code implementing the UCI protocol used to communicate with GUIs and other programs pitting different human and non-human connoisseurs of the game against one another.

Enough typedefs.
Create a new type when using
std::variantby Zhihao Yuan
From the article:
class rock {}; class paper {}; class scissors {}; using hand = std::variant<rock, paper, scissors>;Ignoring the fact that this
handtype comes with heavily overloaded constructors and you can only add free functions, a troublesome issue is that the type-namestd::variant<rock, paper, scissors>will appear everywhere in debuggers and linkers in place ofhand.

Conditionally Trivial Special Member Functions
by Sy Brand
From the article:
The C++ standards committee is currently focusing on adding features to the language which can simplify code. One small example of this in C++20 is conditionally trivial special member functions, which we added support for in Visual Studio 2019 version 16.8. Its benefit isn’t immediately obvious unless you’ve been deep down the rabbit hole of high-performance library authoring, so I’ve written this post to show you how it can make certain generic types more efficient without requiring huge amounts of template magic...
