Utah C++ Programmers has released a video on lambda expresssions in C++.

Illuminating Lambda Expressions in C++

by Richard Thomson

From the video description:

Richard Thomson gives us an insight into lambda expressions in C++ by showing the equivalent manually written function objects.  The presentation proceeds from lambda expressions as originally defined in C++11 and then proceeds through enhancements from C++14, C++17 and finally C++20.

CopperSpice: What is Initialization

By Ansel Sermersheim | Nov 16, 2020 11:05 AM | Tags: None

New video on the CopperSpice YouTube Channel:

What is Initialization

by Barbara Geller and Ansel Sermersheim

About the video:

In this video we look at some of the ways that variables are initialized in C++. We cover the various forms of initialization, the syntax used to specify them, and some of the corner cases that can occur. We also talk about the difference between initialization and initializers, and why being able to recognize an initializer is important for writing correct code.

The basics.

C++ as a Second Language (Chrome University 2020)

by Chris Blume

Summary of the video:

A tour of C++ for experienced/advanced programmers coming from other languages (C/Java/JS/Python/Go/VHDL/etc). Chris Blume explains C++11 features, free functions, include & linkage, destructors & scope, RAII, pass-by-value / -reference, the standard library, and smart pointers...

CopperSpice: Concepts in C++20

New video on the CopperSpice YouTube Channel:

Concepts in C++20

by Barbara Geller and Ansel Sermersheim

About the video:

In this video we look at the feature called Concepts which was added in C++20. We discuss some of the reasons concepts were added to the language, and why concepts as they were accepted are not like the original proposals they started with. We also provide an example of replacing SFINAE with concepts to produce cleaner and more readable code.

New video on the CopperSpice YouTube Channel:

Qualifiers

by Barbara Geller and Ansel Sermersheim

About the video:

In this video we explore the many different kinds of qualifiers available in C++ and explore how they interact. We also cover why you would want to qualify your methods, and a surprising corner case in the way assignment is defined which can lead to very subtle bugs.

CppCon 2019: A State of Compile Time Regular Expressions--Hana Dusíková

By Adrien Hamelin | Sep 11, 2020 01:22 PM | Tags: community

This year, CppCon 2020 is going virtual. The dates are still the same – September 14-18 – and we are aiming for the CppCon live event to have pretty much everything you’re familiar with at CppCon except moved online: multiple tracks including “back to basics” and a new “embedded” track; live speaker Q&A; live talk time zones friendly to Americas and EMEA (and we’re going to try to arrange around-the-clock recorded repeats in all time zones, where speakers who are available can be available for live Q&A in their repeated talks too, and we’ll do that if it’s possible – but we’re still working on it!); virtual tables where you can interact face-to-face online with other attendees just like at the physical event; virtual exhibitor spaces where you can meet the folks on your favorite product’s teams to ask them question face-to-face; pre- and post-conference classes; and even the CppCon house band playing live before every plenary session. All talk recordings will be freely available as usual on YouTube a month or two after the event, but everything else above will be available only live during CppCon week.

To whet your appetite for this year’s conference, here’s another of the top-rated talks from last year. Enjoy – and register today for CppCon 2020 – all the spirit and flavor of CppCon, this year all virtual and online!

A State of Compile Time Regular Expressions

by Hana Dusíková

Summary of the talk:

In this talk I will present an advancement on the Compile Time Regular Expression (CTRE) library. The library was designed with new C++20 features, and it uses novel techniques. This presentation independently sums up the work since my previous CppCon talk about the library.

The primary topic of this talk will be an explanation of the new Deterministic Finite Automaton (DFA) engine in the library and how it's built and optimised during compilation. I will explain the differences and limitations of the new engine in comparison to the previous Back Tracking engine. I will address these differences with a benchmark and I will discuss the generated assembly.

Even if you are not interested in regular expressions, you will learn new techniques in compile-time meta-programming and see new C++20 features in action.
