Design Patterns VS Design Principles: Factory method

by Jonathan Boccara

From the article:

Let’s examine another design pattern in our “Design Patterns VS Design Principles” series, where we relate design patterns to design principles. Today, we focus on the Factory method design pattern.

We’ll see the various forms the Factory method design pattern can take, the differences with the Abstract Factory method, and to which design principle the Factory method pattern relates to...

Faster, Easier, Simpler Vectors - David Stone - CppCon 2021

By Adrien Hamelin | Jul 8, 2022 01:10 PM | Tags: None

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!

Faster, Easier, Simpler Vectors

by David Stone

Summary of the video:

The standard library has the type `std::vector`. It is used ubiquitously as a high-performance container. However, it was standardized in the mid 90s and C++ has seen many changes since then. It has been extended with allocators, move semantics, initializer_list, and much more. Can we do better?

We can. It is possible to write a container and a set of algorithms that are more efficient at run time, have simpler implementations, and have easier, more intuitive APIs. Not only that, but we can also make it easy for users to write their own vector-like containers that make slightly different trade-offs for when you need even more performance, and this presentation includes discussion of several such vectors.

We will go through specific examples of these vector-like types and the algorithms that operate on them, and then take from that general principles of software design. We'll look into how we're limited in what we can do by C++ as it exists today and what up-and-coming proposals can make things even better.

Advancing the State of the Art for std::unordered_map Implementations -- boost.org

By Vinnie | Jul 4, 2022 11:52 AM | Tags: community c++17

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

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

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...
