Here is a useful thing to know that appeared with C++11:
Non Static Data Members Initialization
by Bartlomiej Filipek
From the article:
My short summary for non static data members initialization from modern C++. A very useful feature. Should we use it or not?

First step to a complete integration of the C++ deps manager biicode with the most popular set of C++ libs: Boost libraries.
Boost libraries are now supported in biicode
by Manu Sánchez
From the news:
At biicode we have been working hard to simplify the process of making Boost available for any C++ programmer with just an include. But this is only the start, the project has been released as open source to allow everyone contribute and help.

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:
Elevate Your Code to Modern C++11 with Automated Tooling
by Bjarne Stroustrup
Summary of the talk:
C++ faces two challenges: Helping programmers address the most demanding tasks in terms of performance, scale, and dependability. It must also help programmers be productive writing ordinary maintainable code. There is much more "ordinary code" than there is performance-critical code. Thus, C++ must make simple tasks simple while not getting in the way of tuning software for the last byte and last cycle where that's necessary. This talk focuses on what C++11 and C++14 offers to simplify programming: auto, range-for loops, move semantics, futures, concepts, and more. However, the focus is not primarily on language features: the key is programming: how can we write better, more readable, efficient, and more maintainable code? If you think that the essence of C++ is clever pointer manipulation and huge class hierarchies you may be in for a few surprises.

This is the first episode of cppcast, the only podcast by C++ developers for C++ developers. In this first episode host Rob Irving interviews Jon Kalb about the state of the C++ Community.
cppcast episode 1: Jon Kalb loves the C++ Community
by Rob Irving
About the interviewee:
Jon has been writing C++ for two and half decades, does onsite C++ training, and works on the Amazon search engine for A9.com. He chairs the CppCon and C++Now conferences. He also programs the C++ Track for the Silicon Valley Code Camp and serves as chair of the Boost Libraries Steering Committee.

I wish to introduce the CppCheck tool to the beginner programmers. Cppcheck is a static analyzer for C and C++ code. It is open-source, free, cross-platform and easy-to-use.
Cppcheck
by Andrey Karpov
From the article:
One of the basic advantages of the Cppcheck analyzer is that it is easy-to-use. It is good to teach and study the static analysis methodology: for instance, you install Cppcheck on a Windows system and get a GUI interface allowing you to immediately start checking your projects.

The Rule of Zero revisited: The Rule of All or Nothing
by Arne Mertz
From the article:
In 2012, Martinho Fernandes coined the Rule of Zero in a blog post. In 2014, Scott Meyers wrote a blog post about a concern with that rule and proposed a Rule of Five Defaults.
Back then, I had written a small comment on Scott’s post that deserves some further elaboration. In this post I am going to wrap up my thoughts about the two posts and propose a “Rule of All or Nothing”...

A new blog post at Meeting C++, this time its about std::random_shuffle and C++14:
std::random_shuffle is deprecated in C++14
by Jens Weller
From the article:
So, one of the new things in C++14 is, that the committee has actually started to deprecate (and later remove) a few things from the standard. One of them is a rather awkward function: random_shuffle.

Designing value classes for modern C++
by Mark Mutz
From the talk description:
C++11 is now widely available, and so is C++14. Like for users of the language, C++11/14 is a new language for C++ library writers, too. In this talk, we will walk you through the new C++ features that impact class design...

The article explains why one must never use the (this == 0) expression. It's a very bad code. It being able to work at times doesn't mean anything. By writing (this == 0), you let undefined behavior into your program.
Still Comparing "this" Pointer to Null?
by Dmitry Meshcheryakov
From the article:
In the same way the compiler can optimize the code comparing "this" pointer to null. According to the Standard, this cannot be null and therefore the checks and the corresponding code branches can be eliminated, which will greatly affect the code dependent on the comparison of "this" pointer to null. The compiler has a full right to "break" (actually just break it further) the code CWindow::GetSafeHandle() and generate machine code which doesn't contain the comparison and only reads the class field all the time.
...
GOOD LORD, the "this" pointer equals 0x00000004 on entering the method when compiled in Visual C++ 9, as the pointer initially set to null is adjusted so that it points to the beginning of a subobject of the corresponding class.
