Report from using std::cpp 2019

From the article:

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...

C++17 STL Parallel Algorithms - with GCC 9.1 and Intel TBB on Linux and macOS--Paul Silisteanu

It's coming!

C++17 STL Parallel Algorithms - with GCC 9.1 and Intel TBB on Linux and macOS

by Paul Silisteanu

From the article:

GCC 9.1 has support for C++17 parallel algorithms by using the Intel TBB library. In this article, I will show you how to build Intel TBB from sources on your machine and how to sort a vector of random numbers in parallel using C++17 std::sort...

ACCU Trip report--Kate Gregory

Sweet and short.

ACCU Trip report

by Kate Gregory

From the article:

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

Check it out.

GCC 9.1 Released

From the article:

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...

Curried Objects in C++--Jonathan Boccara

Abstraction to the rescue.

Curried Objects in C++

by Jonathan Boccara

From the article:

Curried objects are like facilitators. They consist in intermediary objects between a caller and a callee, and helps them talk to each other in a smooth way. This ability makes the code simpler and easier to read...

Results summary: 2019 Global Developer Survey "Lite"

Thank you to everyone who responded. As promised, here is a summary of the results, including aggregated highlights of common answers in the write-in responses:


The results have now been forwarded to the C++ standards committee to help inform C++ evolution. Your feedback will be very helpful, and thank you again for your participation!

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

So you should send them.

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

by Jon Kalb

From the article:

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...

Quick Q: What are copy elision and return value optimization?

Quick A: a way to remove copying objects in certain case, improving performance and reducing the constraints on a class (no copy or move needed).

Recently on SO:

What are copy elision and return value optimization?

Copy elision is an optimization implemented by most compilers to prevent extra (potentially expensive) copies in certain situations. It makes returning by value or pass-by-value feasible in practice (restrictions apply).

It's the only form of optimization that elides (ha!) the as-if rule - copy elision can be applied even if copying/moving the object has side-effects...

Conference Report: ACCU 2019--Quentin Balland

Another one.

Conference Report: ACCU 2019

by Quentin Balland

From the article:

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!
