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 some upcoming talks that you will be able to attend this year. Here’s another CppCon future talk we hope you will enjoy – and register today for CppCon 2021 to attend in person, online, or both!

What You Can Learn from Being Too Cute: Why You Should Write Code That You Should Never Write

Friday, October 29 • 1:30pm - 2:30pm

by Daisy Hollman

Summary of the talk:

During the COVID-19 global pandemic, as we all searched for ways to stay connected to the C++ community, I innocently started posting short, 25-line or less C++ snippets of counterintuitive C++ code that I called my "Cute C++ trick of the day." I was floored by the amount of attention these tweets received, with some being viewed more than 30,000 times and liked or retweeted hundreds of times. I received repeated requests to collect these tricks into a library or talk, and this is that talk.

In this presentation, I will dissect a few of my most popular "Cute C++ tricks" to a level of detail not possible on social media platforms like Twitter. I'll talk about how and why these tricks work the way they do, talk about the dark corners of C++ they touch upon, and talk about what you should actually do if you need to produce the same effect in production code. While not targeted at beginners, these tricks span the gauntlet from features that most intermediate programmers are aware of (but never thought to use in a particular way) to dark corners of the language that many of my C++ committee colleagues were surprised to learn about. Throughout it all runs a common thread: learning how to exploit your own curiosity to expand your toolbox, gain a better grasp of the fundamentals of C++, and ultimately, become a better programmer.

Cppcon 2021 A (Short) Tour of C++ Modules--Danila Kutenin

A (Short) Tour of C++ Modules

Tuesday, October 26 • 3:15pm - 4:15pm

by Danila Kutenin

Summary of the talk:

Once you decide to start a big project or a company, it eventually comes down to unifying the build infrastructure. However, hundreds and thousands of compilation units are extremely difficult to maintain to achieve the highest possible performance. Contrary to the belief that you should always trust your compiler, recent micro-architectural breakthroughs from merging two arrays with special instructions to JSON parsing through SIMD showed that compilers are far from understanding every single piece of code you write. In this session we will talk about our experience on how to achieve the highest possible performance without much rewriting of your code, which trade-offs C++ compilers have, how to make the most of your micro-architecture, why unrelated changes may decrease the performance and how to debug them. In the end we will show which compiler options gave us the opportunity to gain 5-15% of performance, stabilized the benchmarks and decreased the build size for search engines, databases and high performance computing.

Cppcon 2021 Back To Basics: Overload Resolution--Barbara Geller and Ansel Sermersheim

Back To Basics: Overload Resolution

Tuesday, October 26 • 9:00am - 10:00am

by Barbara Geller and Ansel Sermersheim

Summary of the talk:

During this talk we will explain the definition of a function overload and what rules the compiler follows to decipher which overload to call. The rules can be complex and may not always do what you expect. We will condense the C++ standard to the essential rules every programmer should be aware of in order to reason through overload resolution.

Knowing how overload resolution works will improve your ability to debug compiler errors and this is vital to write correct code. We will provide simple and concise explanations for various buzzwords like template argument deduction, implicit conversion, standard conversions, and tie-breakers.

This talk is part of the Back to Basics track and the material will be targeted to include all skill levels. Familiarity with C++ is recommended however no prior knowledge of function overloads is required.

CppCon 2021 Code Analysis++--Anastasia Kazakova

Code Analysis++

Tuesday, October 26 • 7:45am - 8:45am

by Anastasia Kazakova

Summary of the talk:

Martin Fowler once wrote that high-quality software is actually cheaper to produce than low-quality software. We agree with that sentiment, and we warmly welcomed the C++ Core Guidelines when they were introduced in 2015. Research and surveys conducted in the C++ Community consistently demonstrate the popularity of the Clang family of tools, as well as the growing demand for static analysis to be added to code editors.

In this talk, we’ll explore the current capabilities of existing C++ static analyzers and discuss some of the enforcements listed in the C++ Core Guidelines from a toolability aspect. We’ll also look into the recent “Simplify C++” trend in the language’s evolution, and to wrap things up we’ll take a look at how technology-specific analysis (like MISRA and AUTOSAR) is being adopted.

A variety of checks will be discussed, from catching a dangling pointer to conforming to the preferred code style and naming scheme. And I want to share a crazy idea I have about gamifying static analysis. Let’s play!

CppCon 2020 Constructing Generic Algorithms: Principles and Practice--Ben Deane

By Adrien Hamelin | Sep 27, 2021 12:48 PM | Tags: community

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.

CppCon 2019 Behind Enemy Lines - Reverse Engineering C++ in Modern Ages--Gal Zaban

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...

CppCon 2020 Building a Coroutine based Job System without Standard Library--Tanki Zhang

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...
