Have you registered for CppCon 2016 in September? Don’t delay – Registration is open now.

While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2015 for you to enjoy. Here is today’s feature:

Concurrency TS Editor's Report

by Artur Laksberg

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

In this presentation we will talk about the new C++ concurrency features that have been included in the Concurrency Technical Specification.

The TS should be of interest to anyone writing concurrent code in C++. The proposal includes improved futures for wait-free composition of asynchronous operations (including their relationship with C++ 'await'), new synchronization constructs as well as atomic smart pointers.

Writing Great Libraries: 89 Easy Steps

by Zach Laine

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Writing code that does what you want it to do, correctly and efficiently, is hard. Doing so when you don't even know yet what you want the code to do yet is quite a bit harder. Yet this is the job of a library writer -- the users of a library may have a very different use case from that of the original author.

How do library writers develop correct and efficient APIs that are also:

- easy to use correctly - hard to use incorrectly - highly reusable - gracefully interoperable with other code

This talk gives lots of practical advice and techniques for accomplishing those goals and more.

C++ User Group Meetings in August

by Jens Weller

From the article:

The monthly overview on the upcoming C++ User Group meetings. As there is again a group meeting at the first, I have to publish this today, so that there will still be some groups not in the listing, as they are publishing their meetings in the coming days. Still, already 26 groups will meet in August!

There are 3 new C++ User Groups: Copenhagen, Singapore, and Gdansk.

Memory consistency made simple(ish)

by Glennan Carnie

From the article:

The C++11 memory consistency model is probably one of the most significant aspects of Modern C++; and yet probably one of the least well-understood.  I think the reason is simple:  it’s really difficult to understand what the problem actually is.

The memory consistency problem is a concurrency problem.  That is, it’s a problem that occurs when we start writing multi-threaded code.  More specifically, it’s a parallelism problem – the real subtleties occur when you have two or more processors executing code...

 

CppCon 2015 Test Driven C++ with Catch--Phil Nash

Test Driven C++ with Catch

by Phil Nash

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

C++ has been notorious for being a second class citizen when it comes to test frameworks. There are plenty of them but they tend to be fiddly to set-up and ceremonious to use. Many of them attempt to follow the xUnit template without respect for the language environment they are written for. Catch is an attempt to cut through all of that. It is simple to get and simple to use - being distributed in a single header file - yet is powerful and flexible. Catch includes a number of innovations that make testing in C++ more natural - and fun - than ever before. This presentation introduces you to the unique approach that Catch brings to unit and integration testing - and how to use Catch to drive your design with TDD or BDD.

He started programming in 1986, completing a BSc Computer Science 1999, before spending three years working for a legal publishing firm, getting chronic fatigue syndrone, quitting, building a music studio, recovering, getting interested in programming again, building a game engine, and stumbling across some generalized solutions to some old problems.

PVS-Studio confesses its love for Linux

You will help greatly if you volunteer to help testing the beta-version of PVS-Studio for Linux.

PVS-Studio confesses its love for Linux

by Andrey karpov

From the article:

PVS-Studio is a tool for bug detection in the source code of programs, written in C, C++, and C#. We are looking forward to the moment that we'll have something to present to this world. I hope this article brought some intrigue, and that Linux developers will want to try scanning their projects with PVS-Studio. If you have time and wish to, I invite you to become a part of the beta-tester team.
