Stupid std::tuple tricks: Selecting via an index sequence
by Raymond Chen
from the article:
Last time, we combined tuples. That’s relatively straightforward. Splitting them apart is harder.

The new book by Nico Josuttis is now available as an ebook draft.
C++ Move Semantics - The Complete Guide
by Nico Josuttis
About the book:
Having 200 pages, the description of move semantics is feature complete now. Only a few chapters about the use of move semantics in the C++ standard library are missing.
The book teaches all aspects of C++ move semantics. Starting from the basic principles it motivates and explains all features and corner cases (such as perfect returning with
decltype(auto)) so that a C++ programmer can understand and use move semantics right in application code, when implementing classes, in generic code, and in foundation libraries.

SYCL is an open standard developed by the Khronos™ Group that enables developers to write code for heterogeneous systems using standard C++.
Ray-tracing in One Weekend with SYCL Part 2
by Codeplay
About the article
C++ Ray-Tracing in a Weekend by Peter Shirley is a great resource to start learning about ray-tracers and how to implement one, and at the same time providing all the source code in a GitHub repository . You can find more information about his books on ray-tracing techniques with accompanying implementations on his blog, and you can also download the books as .pdf, or load them on your Kindle device for free from the GitHub project.
This post follows on from the first part of my blog, where I showed how the I adapted the code from "Ray Tracing in one weekend" to increase performance using SYCL™. The first area I tackled was the rendering.
In this second post I'll show how to use SYCL to improve the performance of this code further using some interesting techniques.

More on the next standard.
C++20: More Details to the Spaceship Operator
by Rainer Grimm
From the article:
The compiler performs quite a clever job when it generates all six comparison operators. On the end, you get the intuitive and efficient comparison operators for free. Let me dive with this post into the details of the spaceship operator...

Are you using tuples?
Stupid std::tuple tricks: Getting started
by Raymond Chen
From the article:
The C++ standard library tuple is quite versatile. It’s a handy way of grabbing a bunch of types or values into a single unit, and the C++ standard library also provides a number of helpers to manipulate them...

Modules, coroutines, concepts, and ranges, oh my. Here comes C++ 20. The big four new features are getting all the buzz, but what about the smaller features?
C++20: The Unspoken Features
by Michele Caini
From the article:
What's new in C++ besides the big four? A lot of things. We certainly won't be able to see them all in one post. Among the most interesting (at least from my point of view) are the following:
- Designated initializers
- Spaceship operator
- Extended range-based for statement
- Pack expansions in lambda init-capture
- Template parameter lists on lambdas
- String literals as template parameters
- consteval and constinit keywords
- Constexpr containers
- Constexpr virtual functions

Usage and internals of std::enable_shared_from_this<T>:
enable_shared_from_this - overview, examples, and internals
by Hitesh Kumar
From the article:
Public inheritance from enable_shared_from_this<T> enables a class T to create additional shared_ptr instances to itself. Typically, enable_shared_from_this holds a weak_ptr to create shared_ptr on demand.

C++20: The Three-Way Comparison Operator
by Rainer Grimm
From the article:
The three-way comparison operator <=> is often just called spaceship operator. The spaceship operator determines for two values A and B whether A < B, A = B, or A > B. You can define the spaceship operator or the compiler can auto-generate it for you...

On which Bjarne Stroustrup describes how C++ has managed to thrive despite many things
Thriving in a Crowded and Changing World: C++ 2006–2020
By Bjarne Stroustrup
From the article:
This paper focuses on the major changes to the ISO C++ standard for the 2011, 2014, 2017, and 2020 revisions.
The standard library is about 3/4 of the C++20 standard, but this paper’s primary focus is on language features
and the programming techniques they support.
