Ordering asynchronous updates with coroutines, part 1, part 2, part 3, part 4, part 5

by Raymond Chen

From the article:

I opined some time ago on the perils of holding a lock across a coroutine suspension point. But say you have a bunch of asynchronous activity that you want to serialize. How can you do that without a lock?

There are a few different scenarios in which you may need to protect asynchronous activity. We’ll look at them over the next few days...

Audio Programming with BASS -- Richard Thomson

Utah C++ Programmers has released a new video.

Audio Programming with BASS

by Richard Thomson

From the video description:

This month, Richard Thomson will give us an introduction to audio programming with the BASS library.  Specifically, we'll look at this library with an eye towards playing back MOD music and triggering events during playback in response to interesting things happening during the score.

BASS is an audio library for use in software on several platforms. Its purpose is to provide developers with powerful and efficient sample, stream (MP3, MP2, MP1, OGG, WAV, AIFF, custom generated, and more via OS codecs and add-ons), MOD music (XM, IT, S3M, MOD, MTM, UMX), MO3 music (MP3/OGG compressed MODs), and recording functions. All in a compact DLL that won't bloat your distribution.

Meeting C++ 2021: choosing the online platform

By Meeting C++ | Sep 8, 2021 08:10 AM | Tags: meetingcpp community

Meeting C++ reveals on which online platform the conference and the online C++ User Group will be hosted this year.

Choosing Hubilo as an online platform for Meeting C++ 2021

by Jens Weller

From the article:

During July and August I did compare many online platforms, to choose the one to host this years online conference and the events of Meeting C++ online in. The winner is Hubilo.

Its been a difficult and time consuming process to compare the various platforms and get a feel for what online events will have a look and feel in 21/22 when choosing a certain platform. I'd like to be able to host all formats of the online User Group in one platform: the talks, the panels and especially the online fairs for C++ jobs/recruiting and tooling. This years conference will host all these event types too!

Meeting C++ has opened this years call for sponsors

Meeting C++ 2021: looking for sponsors

by Jens Weller

From the article:

With the online platform being selected, its finally time to open the call for sponsors for Meeting C++ 2021!

Sponsoring is an easy way to support the work of Meeting C++, as my work is mostly funded through the ticketsales and sponsorships of the yearly Meeting C++ conference. So maybe your employer is interested in sponsoring Meeting C++ 2021?

CppCon 2020 Building an Intuition for Composition--Sy Brand

By Adrien Hamelin | Sep 6, 2021 01:45 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!

Building an Intuition for Composition

by Sy Brand

Summary of the talk:

If you're fed up of reading articles about "monads" and "endofunctors" that don't give you an understanding of how they can actually help your C++ programming, this talk is for you.

Function and data composition are becoming increasingly important in C++ due to features like ranges, continuable futures, and new error handling techniques. Using real-world examples and C++ programming idioms, I'll help you build an intuition for the mathematical concepts which underpin these so that you can make the most of them in your code and build your own abstractions built on the same foundations.

Why do you need the MISRA Compliance report and how to generate one in PVS-Studio?

By Andrey Karpov | Sep 6, 2021 12:42 AM | Tags: sast misra compliance misra c++ misra c misra embedded devsecops

If you are strongly interested in MISRA and would like to understand whether your project meets one of the MISRA association's standards, there is a solution. It's name is MISRA Compliance.

Why do you need the MISRA Compliance report and how to generate one in PVS-Studio?

by Nikolay Mironov

From the article:

To make this simpler, let's take rule 1.1 that has the standard value of the category equal to Required. If you look at the table, you can see that acceptable compliance values for Required are Compliance or Deviations (I'll talk more about the meaning of these statuses later). This means that if your project complies with rule 1.1, or if it complies with this rule with some deviations - everything is fine and you can go to the next rule. If you get at least one hit in Violations or Disapplied, then the project does not comply with MISRA C 2012. If all rules have acceptable values only, congratulations! Your project complies with the MISRA C 2012 standard. If you have a hit in the red zone (the table above), you do not comply with the standard.

CppCon 2019 Back to Basics: Virtual Dispatch and its Alternatives--Inbal Levi

Back to Basics: Virtual Dispatch and its Alternatives

by Inbal Levi

Summary of the talk:

Code efficiency is one of the strongest features of modern C++, therefore broadly used in industries with a need for high performance, such as Real-Time or Embedded Systems.

In this talk, we will go through the search for high run-time efficiency using the dispatch mechanism.

We will start by providing tools for understanding and estimating run-time performance cost.

Next, we'll analyze a test case, and dive into some of the most fundamental components of the language such as inheritance, and templates.

We will continue by introducing implementations which produce high run-time efficiency code such as CRTP, std::variant and visitor, and use them to maximize performance.

Finally, we will do benchmarking and draw conclusions, and try to answer the question -
How can we use C++ ideally for achieving high-performance efficiency?

Calling Functions: A Tutorial

by Klaus Iglberger

Summary of the talk:

How is a function call resolved? How does the compiler find the right function and how does the compiler choose from a set of available functions? This talk will give an overview of the individual steps taken during the resolution of a function call. It will primarily focus on the different kinds of name lookup, argument deduction, and on overload resolution. Attendees will gain insight into the mechanics of (un-)qualified lookup, argument dependent lookup, two-phase lookup, name hiding, SFINAE, (viable) candiate functions, and ambiguous function calls. They will leave the talk with a much better understanding of the (sometimes surprising) details of function calls.
