Advancing the State of the Art for std::unordered_map Implementations -- boost.org
Several Boost authors have embarked on a project to improve the performance of boost's associative containers.
Boost.Unordered
by boost.org
About the improvements:
Boost.Unordered's new implementation of std::unordered_map (and multimap, set and multiset variants), and to extend its portfolio of available containers to offer faster, non-standard alternatives based on open addressing.
The first goal of the project has been completed in time for Boost 1.80 (due August 2022). We describe here the technical innovations introduced in boost::unordered_map that makes it the fastest implementation of std::unordered_map on the market.

C++20: The Small Pearls - Rainer Grimm - CppCon 2021
Registration is now open for CppCon 2022, which starts on September 11 and will again be held both in person and online. To whet your appetite for this year’s conference, we’re posting videos of some of the top-rated talks from last year’s conference. Here’s another CppCon talk video we hope you will enjoy – and why not register today for CppCon 2022 to attend in person, online, or both!
C++20: The Small Pearls
by Rainer Grimm
Summary of the video:
C++20 has way more to offer than the big four concepts, ranges, modules, and coroutines.
Here are a few of the shining pearls.The spaceship operation automatically creates the six comparison operators. Thanks to consteval, constinit, and improved templates, programming at compile time becomes more powerful. std::span supports safe access to contiguous memory blocks. An enhanced time library and a new type date. Comfortable formatting of data thanks to std::format. Easily synchronize or coordinate threats with semaphores or latches and barriers. An improved thread that maintains itself and supports interruption. Thanks to the synchronized output streams, write operations in the concurrent environment do not end in a mess.

Embracing Modern C++ Safely, Book Review--Bartlomiej Filipek
Did you read it?
Embracing Modern C++ Safely, Book Review
by Bartlomiej Filipek
From the article:
C++11 has been around for around 11 years and C++14 for 8. From my experience, I see that even today, many companies struggle to use those standards in production in the most efficient way. As always, with new stuff came benefits, risks, and increased learning effort. Fortunately, with a new book written by top C++ Experts, we have a solid guide on what is safe and what might be problematic in Modern C++.
The book is called “Embracing Modern C++ Safely”.
Let’s see what’s inside...
