C++ Core Guidelines: The Standard Library

by Rainer Grimm

Curiously, there is no section to the algorithms of the standard template library (STL) in this chapter. Curiously, because there is a proverb in the C++ community: If you write an explicit loop, you don't know the algorithms of the STL. Anyway. Only for completeness, let me start with the first three rules which provide not much beef...

Report from using std::cpp 2019

On March, 7th, we had the sixth edition of using std::cpp (the C++ conference in Spain). The conference was again a on-day free event, and as every other year it was hosted at the Higher Polytechnic School of University Carlos III of Madrid in Leganés.

As many other years roughly 200 participants attended the conference. Most of the attendees were coming from industry...

ACCU Trip report

by Kate Gregory

In early April I was lucky enough to go to Bristol in the UK for the annual ACCU conference. This has been an aspirational conference for me, one I attended before speaking at and am always delighted to attend. This year I was invited to keynote, and it turned out to be the closing keynote, which meant I was not done with all my talks until the conference was over! Nevertheless I enjoyed the week tremendously...

GCC 9.1 Released

In this release C++17 support is no longer marked experimental. The C++ front-end implements the full C++17 language (already previous GCC major version implemented that) and the C++ standard library support is almost complete. The C++ front-end and library also have numerous further C++2a draft features. GCC has a new front-end for the D language. GCC 9.1 has newly partial OpenMP 5.0 support and almost complete OpenACC 2.5 support...

Top Ten Reasons To Send Your Developers to CppCon (or any C++ Conference)

by Jon Kalb

Sending software engineers to conferences is both a time and money expense, but conferences exists because they provide value to attendees and companies that send them. Some of the value may be obvious, some may not. Here is a list of the top business reasons to send your developers to CppCon or any other C++ conference...

Conference Report: ACCU 2019

by Quentin Balland

I had the pleasure to attend to the ACCU2019 at Bristol which was my first cpp centred conference (the first of a long series I hope :p) and it was amazing in a different aspect.


It is a 4 days conference that occurs every year between March and April in the Marriott hotel in Bristol.


Amazing people, very inclusive and easy to talk to everyone!

How to Write Safe and Expressive Multi-Threaded Code in C++11

by Louis-Charles Caron

I started writing multi-threaded code two years ago. Two years and one day ago, I would start sweating at the sound of the the words thread and mutex. But after literally a few days of practice (and, I admit, a 3-day course on multi-threading and C++11), I figured the basic principles are quite understandable.

Typical multi-thread problems can be solved by using a handful of tools. Admittedly, complex problems are even more complex when they appear in multi-threaded code, but I did not happen to run into those yet.

Since C++11, one now finds the necessary multi-threading tools in the C++ standard library. Finally! We can write multi-threaded code in pure C++.

The multi-threading part of the C++11 library is functional: it is simple and to the point. However, it is nearly impossible to write clear and expressive multi-threaded code using only the C++11 tools. And when multi-threaded code is not clear, it tends not to be safe.

In this article, I introduce some multi-threading tools you will find in the C++11 standard library through a code example. Although simple, this example will clearly demonstrate the shortcomings of the C++11 standard library. Then, I present safe: a small header-only C++11 library I designed to make my multi-threaded code more expressive, and ultimately safer...

Engage, Entertain, Educate: Technical Speaking that Works

by CppCon

Attendees at last year’s Engage, Entertain, Educate (EEE) workshop wrote to us: “Please rehire!” “Please repeat!” and “You should have this class every year.”

ACCU 2019 Slides and Trip Report

I attended ACCU 2019 a couple of weeks ago, where I was presenting my session Here's my number; call me, maybe. Callbacks in a multithreaded world.

The conference proper started on Wednesday, after a day of pre-conference workshops on the Tuesday, and continued until Saturday. I was only there Wednesday to Friday...
