Stupid std::tuple tricks: Creating more interesting index sequences
by Raymond Chen
From the article:
Last time, we wrote offset_sequence_t, which takes an existing sequence and adds a fixed value to each element. This is the sort of index manipulation you may want to generalize. So let’s generalize it...

Stupid std::tuple tricks: Creating interesting index sequences
by Raymond Chen
From the article:
We saw last time that manipulating tuples boils down to the index_sequence. The problem is that the C++ standard library doesn’t provide very much in the way of helpers to manipulate these index sequences...

Stupid std::tuple tricks: Selecting via an index sequence, part 2
by Raymond Chen
From the article:
Last time, we developed the select_tuple function which takes a tuple and an index sequence and produces a new tuple that selects the elements based on the index sequence...

C++ Template: A Quick UpToDate Look(C++11/14/17/20)
by Vishal Chovatiya
From the article:
I know, it’s been a while since the last time I published something newbies-friendly on my blog. The main reason is that most of my readers are either experienced devs or from C background having modest C++ encounter. But while programming in C++ you need a completely different mindset as both C & C++ belongs to different programming paradigm. And I always strive to show them a better way of doing things in C++. Anyway, I found the topic which is lengthy, reasonably complex(at least it was for me), newbies-friendly as well as energizing for experienced folks(if Modern C++ jargons, rules & features added) i.e. C++ Template.
I will start with a simple class/function template and as we move along, will increase the complexity. And also cover the advance topics like the variadic template, nested template, CRTP, template vs fold-expression, etc. But, yes! we would not take deeper dive otherwise this would become a book rather than an article.

Getting up to date.
The C++ Lambda Story Book
by Bartlomiej Filipek
From the article:
Lambda Expressions appeared in C++11, and since then they become one of the most distinguishing features of Modern C++. What’s more, with each revision of the Standard the ISO Committee improved the syntax and capabilities of lambdas, so they are even more comfortable to use.
Read on to see how you can learn all the details of this powerful modern C++ feature.

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.

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.

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.

Copy Elision
by Barbara Geller and Ansel Sermersheim
About the video:
In this video, we look at what copy elision is, and in the process define elision and what it means to copy. We also talk about why you would want to elide copies, and why this feature needed explicit permission in the standard.
