CppCon 2020 Program Available

From the article:

The Main Program for CppCon 2020 is now live!

We’ll have over seventy-five regular sessions delivered by the best C++ presenters in the industry, many returning from previous years as well as some exciting new voices. We’ll have five or six concurrent tracks full of sessions containing C++ best practices and what you need to know about the brand spanking new C++20...

CppCon 2019: Non-conforming C++: the Secrets the Committee Is Hiding From You--Miro Knejp

By Adrien Hamelin | Sep 2, 2020 12:53 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!

Non-conforming C++: the Secrets the Committee Is Hiding From You

by Miro Knejp

Summary of the talk:

These days everyone talks about conforming and portable C++. Compiler vendors celebrate increasing conformance. Committee agents blind us with new shiny toys coming to the language. But there is a darker side to C++. A C++ you are not supposed to know about.

What if I told you there was more to C++ than what the agents of The Committee want us to believe? Over decades programmers all around the world have added features to the language in form of compiler extensions that let us do even greater things. Some are completely new, and some are lifted from C to C++ to allow some interesting, and sometimes more efficient, application.

We will see how statements can become expressions, how "goto" with extra superpowers can make your programs faster, and why there exists an operator named after a famous rock star. These are just a few examples of what to expect as listing any more would draw unwanted attention from The Committee. Unfortunately, because these extensions are not part of ISO C++, using any of them comes at the expense of portability. Or does it?

Write cleaner, safer, modern C++ code with SonarQube

SonarSource will present a 30min webinar Wednesday, Sept 2 at 15:00 GMT to show how you can use SonarQube and SonarLint static analysis to write better C++. Even if you can't attend, sign up and we'll send you a link to the recording afterward.

Write cleaner, safer, modern C++ code with SonarQube

by SonarQube

From the announcement:

As a C++ Developer, you know that writing clean, secure, modern C++ code is important for you and your users. At SonarSource, we know that only developers can truly impact Code Quality and Security, so we put the power in your hands.

SonarQube makes C++ development easier with static code analysis that's powerful, fast, and accurate - right out of the box. Analysis is easy to integrate into your workflow and works with most common compilers, including many for embedded systems. Come see for yourself how you can make your C++ projects more reliable and secure.

std::midpoint? How Hard Could it Be?

by Marshall Clow

Summary of the talk:

The standards committee adopted "P0811: Well-behaved interpolation for numbers and pointers" for C++20.
It includes a new library call `std::midpoint`.
The paper says "The simple problem of computing a value between two other values is surprisingly subtle in general."

In this talk, I will explore this simple call, provide a history of the development in libc++, and show some of the pitfalls.
Undefined behavior will rear its ugly head, along with numeric representations, and the arcane C promotion rules.

Along the way, we'll talk about testing, and why writing extensive tests helps everyone.

Path Tracing Three Ways: A Study of C++ Style

by Matt Godbolt

Summary of the talk:

C++ is a multi-paradigm language allowing us as developers to pick and choose among a variety of styles: procedural, functional, object oriented, hybrids, and more. How does the style of programming we choose affect code clarity, testability, ease of changes, compile time and run-time performance?

In this talk Matt will show a toy path tracer project (a form of ray tracer) implemented in three different styles: traditional object oriented, functional, and data-oriented design. He'll then compare and contrast his experiences developing in each case, showing how often the compiler is able to reduce each style to similar performing code. There's certain to be some surprises - and of course some Compiler Explorer usage!
