Many changes for the better.
C++ 20: The Core Language
by Rainer Grimm
From the article:
My last post C++20: The Big Four started with an overview of concepts, ranges, coroutines, and modules. Of course, C++20 has more to offer. Today, let's continue my overview of the core language...

Executors - of which P0443R11 is one of the latest iterations - is poised to be the most fundamental library addition to C++23.
A Universal Async Abstraction for C++
By Corentin Jabot
From the article:
What is it about?
It is first and foremost a quest to find the most basic building blocks on top of which one could build asynchronous, concurrent and parallel code, whether it be on a small chip or a supercomputer with thousands of CPUs and GPUs.
This is not an easy task and has kept many experts and many companies busy for many years.

Yes. I need the memory management and need it better, than the standard library provides.
WIMSL: advanced memory management.
by Sergey Strukov
From the article:
This article describes some advanced memory management features, badly missed in the C++ standard library.

How would you look for an item in a tuple by the item's type, and return the item's index within that tuple?
Access tuple-like container by type to return an index
by Krzysztof Ostrowski
From the article:
Presentation of a technique that composes an application of a lazy fold expression, and an idea of type embellishment that introduces an implicit context in which the current tuple element is embedded.

Good practices for setting up include files are key to keeping large code-bases manageable, in pre-modules C++, and this article presents 15 rules to keep you on the right track.
C/C++ Include Guidelines
by Thomas Young
From the article:
The rules listed here are relatively mechanical, by which I mean that these are things that can be applied locally to individual bits of source code, without strokes of genius or flashes of inspiration, but with the possibility to nevertheless significantly improve code organisation, which is useful particularly in the case of large legacy code bases.

Simple and sweet.
How to Merge Consecutive Elements in a C++ Collection
by Jonathan Boccara
From the article:
Merging identical consecutive elements in a collection is a recurring need, in C++ or elsewhere in programming.
For example, we could want to aggregate a collection of hourly results into a collection of daily results: all the results of each day get aggregated into one for that day. In this case, being “identical” means being on the same day, and “aggregating” means taking two results with a common date, and creating a result at this date and with the sum of their amounts...
