ACCU 2020 Call for Proposals

The ACCU 2020 is now putting together its program, and they want you to speak on C++. The ACCU has strong C++ tracks, though it is not a C++-only conference. If you have something to share, check out their

Call for Proposals

by the ACCU

About the conference:

Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, Mercurial, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.

The ACCU Conference is put on by ACCU (, but is open to anyone who wishes to be there either as a presenter or an attender.

The Call for Papers lasts for about 3 weeks and will close on Friday 2019-10-25 23:59+01:00.

Cppcon 2019 Milestone | New Home | Trip Reports--Jon Kalb

Many things happened.

Milestone | New Home | Trip Reports

by Jon Kalb

From the article:

CppCon 2019 was the first year in our new home at the Gaylord Rockies in Aurora, Colorado.

Long before I’d ever done it, I told people that I thought that moving a conference is almost as much work as starting one from scratch. Now that I have moved a conference, I’ve learned that started a conference from scratch is actually easier than moving that conference after it has been growing in one location for five years...

Join the Maryland C++ User Group

If you live in the area.

Join the Maryland C++ User Group

From the article:

After looking for and failing to find a C++ user group in Maryland, I decided to start one. If you live in the Baltimore/DC/NoVA area, use C++ for work or pleasure, and are interested in attending monthly-ish meetings related to C++, please join the meetup group at Topics for discussion will include current (C++11/14/17) features, the upcoming C++20 standard, build tools, standard containers and algorithms, design patterns, and pretty much anything else that might benefit a C++ developer...

C++ Russia 2019 Piter

C++ Russia 2019 Piter will be held in Saint-Petersburg, October 31 – November 1, 2019.

C++ Russia 2019

From the article:

Two days, three tracks and dozens of in-depth technical talks about C++: concurrency, performance, architecture, environment — all you need to make your code perfect.

Keynote by Sean Parent, Eric Niebler and Ivan Čukić.

Also at the conference: Marshall Clow, Björn Fahller, Maxim Khizhinsky, Hana Dusíková, Rainer Grimm and many others.

C++ Russia is not only the talks but also networking with hundreds of colleagues from Russia and Europe. Due to dedicated discussion zones, all the speakers have after their talks, all the questions will be answered.

And in the evening you can participate in BoF-sessions where the most uncommon ideas are born.
Fourteen talks will be entirely in English.

CppCon 2019: De-fragmenting C++: Making Exceptions and RTTI More Affordable and Usable--Herb Sutter

What do you think about it?

De-fragmenting C++: Making Exceptions and RTTI More Affordable and Usable

by Herb Sutter

From the video:

A fundamental reason why C++ is successful and loved is its adherence to Stroustrup’s zero-overhead principle: You don’t pay for what you don’t use, and if you do use a feature you can’t reasonably code it better by hand. In the C++ language itself, there are only two features that violate the zero-overhead principle, exception handling and RTTI – and, unsurprisingly, these are also the only two C++ language features that every C++ compiler has switches to turn off and that are regularly discouraged or even banned. This matters because not using these features is the largest current cause of fragmentation of the C++ community into incompatible dialects, and the cause of recurring problems including type confusion security vulnerabilities arising from “didn’t down-cast using dynamic_cast because that would be too slow.” This talk is about ongoing long-term efforts to try to unify the community in this area, not by replacing exceptions and RTTI, but by doubling down: fully embracing exceptions and RTTI, and improving them so they can be zero-overhead too.

CppCon 2019: Better Code: Relationships--Sean Parent

More are coming!

Better Code: Relationships

by Sean Parent

From the video:

Computer scientists are bad at relationships. Nearly every program crash is rooted in a mismanaged relationship, yet we spend most of our time discussing types and functions and not the relationships connecting them together. This talk looks at common ways data and code are connected in an application, how those relationships are typically represented, and the problems caused by the use, and misuse of these paradigms. Then we'll look at ways to model these relationships in C++ and use them to build correct applications.

CppCon 2019: Applied WebAssembly: Compiling and Running C++ in Your Web Browser--Ben Smith

The first videos are becoming available.

Applied WebAssembly: Compiling and Running C++ in Your Web Browser

by Ben Smith

From the video:

WebAssembly is a new technology in all modern browsers designed to let you run high-performance code. Maybe you've heard of WebAssembly before, read an article or two, or even tried to use it with your software project. Since WebAssembly is a low-level language, it's easy to get bogged down in the technical details, and leave without knowing whether WebAssembly will be useful for you. In this talk, I'll take a top-down approach, showing a real problem and how WebAssembly can help.

From August to December this year, I'll be teaching C++ to students at Morehouse College. Having a tool like Compiler Explorer is invaluable as a teaching aid, since it allows the students to immediately see C++ compilation results, on any device that has a web browser. But Compiler Explorer and tools like it require a server to do compilation, so they're hard to use offline. With WebAssembly, we can run the compiler client-side, in the browser, no server required.

First, I'll show how I ported the clang compiler and linker to WebAssembly. Since Clang 8 supports WebAssembly as a compilation target, we can even run the resulting executable sandboxed in the browser. Next, we'll dive into how Clang compiles C++ constructs into WebAssembly. Finally, we'll look at some of the new WebAssembly features in development.
