The future.

Instructor Interview: Mateusz Pusz / C++ Concepts

Summary of the video:

In this week’s instructor interview, Kevin Carpenter welcomes Mat Pusz for a discussion of his CppCon Academy class, C++ Concepts: Constraining C++ Templates in C++20 and Before. Mat quickly demonstrates the power and importance of constraining types when calling functions. His class will cover how to do this with the new concepts feature in C++20 and also how to do it if you are not yet using 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?

HPX V1.5 released -- STE||AR Group

By Hartmut Kaiser | Sep 2, 2020 09:33 AM | Tags: performance parallelism heterogeneous computing distributed computing concurrency c++20 c++17 c++14 c++11

The STE||AR Group has released V1.5 of HPX -- A C++ Standard library for parallelism and concurrency.

HPX V1.5 Released

The newest version of HPX (V1.5) is now available for download! This is a big release with many changes and improvements. We have added numerous new features, adapted a lot of facilities to improve C++20 conformance. We have also continued our work on modularizing and making HPX lighter, improved its usability, stability, and performance. Please see here for full release notes.

    HPX is a general purpose parallel C++ runtime system for applications of any scale. It implements all of the related facilities as defined by the C++ Standard. As of this writing, HPX provides the only widely available open-source implementation of the new C++17 parallel algorithms. Additionally, HPX implements functionalities proposed as part of the ongoing C++ standardization process, such as large parts of the features related parallelism and concurrency as specified by the upcoming C++20 Standard, the C++ Concurrency TS, Parallelism TS V2, data-parallel algorithms, executors, and many more. It also extends the existing C++ Standard APIs to the distributed case (e.g. compute clusters) and for heterogeneous systems (e.g. GPUs).

    HPX seamlessly enables a new Asynchronous C++ Standard Programming Model that tends to improve the parallel efficiency of our applications and helps reducing complexities usually associated with parallelism and concurrency.

 

Cppcon: Instructor Interview: Phil Nash / Accelerated Test Driven Design

Another interesting interview.

Instructor Interview: Phil Nash / Accelerated Test Driven Design

Summary of the video:

In this week’s instructor interview, Kevin Carpenter welcomes Phil Nash for a discussion of his CppCon Academy class, Accelerated TDD: For More Productive C++ . Phil shares the origin story of Catch, the popular testing framework that he authored to support better testing in C++. Kevin has taken a previous CppCon Academy class on testing with Phil. Phil explains that he focuses less on what TDD is (which can be explained in five minutes using one slide) and more on how to apply and get the benefits of TDD in real-world code bases.

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.
