Law of Demeter: A Practical Guide to Loose Coupling
by Kris Jusiak
Summary of the video:
In this practical session, we will go through examples that follow and/or violate the Law of Demeter principle (LoD) [1].
We will take a deep dive into what kind of design issues that exposes and how to fix them.
Additionally, we will focus on the testing aspect of following the LoD principle together with Single Responsibility and Dependency Inversion principles.At the end of this session, the audience will have a better understanding of how to write a loosely coupled code, how to easily test it and why the Law of Demeter principle is so important in Software Design.
Let's !"only talk to our immediate friends" at CppCon-2021!

A CppCon 2022 talk has been announced:
Herb Sutter live in person at CppCon 2022
From the announcement:
C++ Complexity: The Subtle Culprits ("Simplifying C++" #9 of N)
“What makes C++ so complex, and what can we do about it?” In past talks, Herb has already done deep dives on most of the major causes of C++’s complexity and potential directions for solutions.
In this brand-new talk, we delve into the “long tail” of subtle culprits… many of which turn out to be related by a common theme...

Implementing C++ Modules: Lessons Learned, Lessons Abandoned
by Cameron DaCamara & Gabriel Dos Reis
Summary of the video:
C++ Modules were designed to bring more safety to your programs, while dramatically reducing compile time, resulting in overall increased productivity. How can your C++ toolchain meet this challenge? What can you do to take advantage of these new functionalities available in your toolbox? In this talk, we share lessons learned from implementing Modules based on the singular idea of providing robust support through the entire toolchain (from the lexer through the linker, the IDE, the build system, etc.), debunking the misconception that C++ Modules are just some syntactic sugar that is compiled away by the front-end. The challenges that any C++ compiler implementer faces include: (1) how to satisfy the requirements of merging materialization of declarations -- needed for sound handling of the global module fragments, in particular, as found in header files and header units – with associated performance cost; (2) how to take advantage of the One Definition Rule guarantees provided by named modules. They must address those challenges without compromising efficiency and static semantics. These lessons are valuable not just to C++ tools developers, but to ordinary C++ programmers as well, shedding light on how speed and safety gains are achieved by staying close to the spirit of the original C++ Modules design (“take the ODR as foundational”), and how you can put them to good use in the architecture of your programs and libraries.

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
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.
