I've been looking at the BlackBerry 10 NDK the last weeks, and did write about it to share some thoughts and results.
Revisiting the BlackBerry 10 NDK
by Jens Weller
From the article:
The last few weeks I did look again at the BlackBerry 10 NDK, as a client had asked for help and training. I offered to adapt my Qt Introduction course to the BlackBerry plattform, and offered my advice...
Before I start, a short paragraph about Apps and C++. People coming from Java or .NET often don't understand the need to make Apps in C++...

Danny Kalev wrote a nice article yesterday about a new C++ feature -- actually, two related C++14 features -- that were just added to the draft Standard in April and will be coming to real compilers in the near future.
A Glimpse into C++14: Combine Flexibility and Performance with Dynamic Arrays and Runtime-Sized Arrays
by Danny Kalev
From the article:
C99 introduced the notion of variable length arrays: stack allocated built-in arrays whose size is determined at runtime. C++ lacks a similar feature, to the discontent of many a programmer. However, two recent proposals for adding dynamic arrays and runtime-sized arrays to C++14 are closing the gap at last. Learn how to use these new features to imitate C99’s variable length arrays in C++...

A nice piece of writing on a C++11 feature:
Inherited Constructors in C++11
by Marius Bancila
From the article:
In C++, a function in a derived class with the same name as one (or a set of overloads) in a base class, hides the function (or the overloads) from the base class. Here is an example...

Moving Data and Address Arithmetic
by Andrew Koenig
From the article:
Programs that don't care about the addresses of their data rarely need to move those data. After all, we can view the whole point of moving an object as a way of changing the object's address without changing its contents...

The solution to the latest GotW problem is now available. In this Item, the focus is on analyzing and managing compile-time dependencies.
by Herb Sutter
From the article:
Managing dependencies well is an essential part of writing solid code. C++ supports two powerful methods of abstraction: object-oriented programming and generic programming. Both of these are fundamentally tools to help manage dependencies, and therefore manage complexity. It’s telling that all of the common OO/generic buzzwords—including encapsulation, polymorphism, and type independence—along with most design patterns, are really about describing ways to manage complexity within a software system by managing the code’s interdependencies.
When we talk about dependencies, we usually think of run-time dependencies like class interactions. In this Item, we will focus instead on how to analyze and manage compile-time dependencies. As a first step, try to identify (and root out) unnecessary headers.
Guideline: Never #include unnecessary header files.
Guideline: Prefer to #include <iosfwd> when a forward declaration of a stream will suffice.
Guideline: Never #include a header when a forward declaration will suffice.

Overload 116 is now available. It contains the following articles, and more:
When is the use of auto good, and when is it evil?
Alex Fabijanic and Richard Saunders continue to explore dynamic solutions in C++.
How hard can it be to make a file in C++ with international text literals in its name? Alf Steinbach shows us how to write a file called π.recipe.
How low can latency really get?
... and more!

Recently on SO:
override keyword in C++
I am a beginner in C++. I have come across
overridekeyword used in the header file that I am working on. May I know, what is real use ofoverride, perhaps with an example would be easy to understand.

Today in Dr. Dobb's:
An Important Move Optimization Is Nearly Invisible
by Andrew Koenig
From the article:
Last week, we looked at subtle differences between copying and moving a container (a
stringin this example) in the context of passing arguments to functions. Curiously, one of the biggest differences between copying and moving happens in code that we don't write. ...The improvements in robustness and functionality that stem from moving instead of copying are, in my view, at least as important as the optimization. ...

GotW #94 Solution: AAA Style (Almost Always Auto)
by Herb Sutter
From the article:
4. When declaring a new local variable
x, what advantages are there to declaring it usingautoand one of the two following syntaxes:(a)
auto x = init;when you don’t need to commit to a specific type? (Note: The expressioninitmight include calling a helper that performs partial type adjustment, such asas_signed, while still not committing to a specific type.)(b)
auto x = type{ init };when you do want to commit to a specific type by naming a type?
