In this version there are improvements, which, in my opinion, deserve a small note.

Useful Improvements in the PVS-Studio 6.17 Release

by Andrey Karpov

From the article:

A much more interesting feature is that a mechanism of virtual values was significantly redesigned in the kernel of C++ analyzer. For example, now the analyzer performs a double loop passage, which allows it to define the range of possible values of variables, changing in a loop, more accurately. So don't be surprised if the analyzer starts issuing many warnings for that code which used to seem correct for the analyzer.

Calls for Lightning Talks and Open Content

From the article:

Less that 30 days out from CppCon 2017, regular session and poster submissions are closed, both of the field trip tours are sold out, and most of our official hotel blocks are either closed or sold out.

But, even now, there are still conference opportunities. There is still over two weeks left of regular registration, we are still accepting class registrations, we have rooms available in some of our official hotel blocks, and it isn’t too late to attend sessions for free by signing up as a volunteer.

To day we are also opening up two ways to present at the conference.

How to use Visual:

Visual C++ for Linux Development with CMake

by Marc Goodner

From the article:

In Visual Studio 2017 15.4 you can now target Linux from your CMake projects. This enables you to work on your existing code base that uses CMake as your build solution without having to convert it to a VS project. If your code base is cross-platform you can target both Windows and Linux from within Visual Studio.

This post will give an overview of the CMake support for Linux in Visual Studio. You can go here to learn more about CMake in Visual Studio generally.

Top 20 C++ multithreading mistakes and how to avoid them

by Deb Haldar

From the article:

Threading is one of the most complicated things to get right in programming, especially in C++. I've made a number of mistakes myself over the years. Most of these mistakes were  luckily caught in code review and testing ; however, some arcane ones did slip through and make it into production code and we had to patch live systems, which is always expensive.

In this article, I've tried to catalog all the mistakes I know of, with potential solutions. If you know any more pitfalls, or have alternative suggestions for some of the mistakes – please leave a comment below and I'll factor them into the article.

C++17 in detail: Parallel Algorithms -- Bartlomiej Filipek

Let’s see how C++17 can make writing parallel code a bit easier.

C++17 in details: Parallel Algorithms

by Bartlomiej Filipek

From the article:

With C++17 we get a lot of algorithms that can be executed in a parallel/vectorized way. That’s amazing, as it’s a solid abstraction layer. With this making, apps is much easier. A similar thing could be achieved possibly with C++11/14 or third-party APIs, but now it’s all in the standard.
