Paradigms, Polymorphism, and Generic Programming
by Barbara Geller and Ansel Sermersheim
About the video:
We had no idea the word paradigm could actually be a useful term. Come watch our new video and find out what we learned. It is both more complex and more interesting than you might think.

Audio Programming with Marsyas
by Richard Thomson
From the video description:
Marsyas is an open source software framework for audio processing with specific emphasis on Music Information Retrieval applications. [...] Marsyas has been used for a variety of projects in both academia and industry.
This month, Richard Thomson will give us an introduction to the Marsyas API. We'll take a look at how to use this library to extract musical score features from an audio file.

Registration is now open for CppCon 2021, which starts on October 24 and will 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 our most recent in-person conference in 2019 and our online conference in 2020. Here’s another CppCon talk video we hope you will enjoy – and why not register today for CppCon 2021 to attend in person, online, or both!
Constructing Generic Algorithms: Principles and Practice
by Ben Deane
Summary of the talk:
"You have all these algorithms at your disposal. *Learn them.*"
-- Sean Parent, GoingNative 2013.Great advice, and the algorithms can do a lot. But they can't do everything, and the fixed set in the standard was never meant to be the last word in every problem. Sometimes we do need to write our own solutions. What are the best practices for that?
This talk examines how to build our own algorithms. We'll start with a raw loop that solves a nontrivial problem, and turn it into a generic algorithm capable of supporting a wide variety of use cases without loss of expressivity or efficiency.
Along the way we'll consider algorithmic patterns, how to structure the
interface, how the types interact, iterator category concerns, testing, and
more. We'll look at how ranges and concepts help us to refine and focus things.We'll also see where the existing algorithms fall short, and take a look at some non-obvious use cases, including some minor modifications or wrappings that give us extra flexibility.

Behind Enemy Lines - Reverse Engineering C++ in Modern Ages
by Gal Zaban
Summary of the talk:
What do C++ programs really look like? When developers think about hierarchy and virtual calls they see it as design patterns and code but reverse engineers look at it from a different angle, they think about Assembly puzzles.
C++ is known as a tangled language, templates, lambdas and pointers. All of these features create a jungle of objects intended to make life easier for the programmer. But once the program is compiled, the target program is no longer what it once seemed.
Reversing C++ programs is tedious, demanding, and requires rebuilding inheritance, identifying templates and tainting program flow in order to combat the ties of function overloading and class utilization.
C++ Binaries are a world of mysteries. In my presentation I am going to show how C++ binaries looks like after compilation and how reverse engineers see C++ binaries and understand their logic...

Building a Coroutine based Job System without Standard Library
by Tanki Zhang
Summary of the talk:
A job system is a common game engine component to improve total CPU throughput. In this talk, I will walk through building a coroutine-based job system and explain the advantages of using coroutines over the typical ways to build a job system.
We shipped coroutines in C++20, but why does it matter for users, especially since there’s no standard library support? The answer is the coroutine semantics. Developers can customize the behavior of `co_return`, `co_yield`, `co_await` to build their own systems without any dependency of the standard library. For game developers, this is important because many game studios forbid the use of the standard library. The coroutine language feature itself is flexible enough to build a system with 100% control, which is exactly what engine developers want—no black box, no magic.
I will discuss the design decision I made, trade-offs, and current limitations. This talk is a crash course for system developers who want to build systems independently from the standard library and will also discuss possible future directions for this language feature.
This is an advanced coroutine talk and I expect attendees to have basic understanding about how (c++)coroutine works. Here is a useful link for some related materials if you want more information before attending this talk: https://gist.github.com/MattPD/9b55db...

Compiled C++ Coding Standards
by Valentin Galea
Summary of the talk:
Coding conventions, guidelines and standards are a perennial effort of software development. Lots of work goes into preparing and writing them but arguably less in following them - partly because these are documents usually maintained outside of main development, so they evolve separately and often retroactively.
We will show a novel model whereby the coding standard chosen by a team is a 'live' source code file integrated into a production repository so that it participates in compilation. This immediately brings a couple of advantages that we will explore in detail, as well as the implications it has in the context of a full team of developers.
As a practical example, the coding standard files of Splash Damage - a game development company - will be shown and discussed, detailing the various C++ aspects they deal with it and the techniques encouraged therein. Going further than the code, we'll talk about the human factor and how standards are written, evolved and championed across a large company in the face of different constraints between projects and teams.

C++20 String Formatting Library: An Overview and Use with Custom Types
by Marc Gregoire
Summary of the talk:
C++20 introduced a nice formatting library with std::format(). This session will explain what the formatting library provides, how to use all of its functionality, and most importantly, how you can customize it so that you can use formatting strings that include your very own custom types and custom formatting parameters, and of course, how to handle errors.
