Safe Clearing of Private Data
We often need to store private data in programs, for example passwords, secret keys, and their derivatives, and we usually need to clear their traces in the memory after using them so that a potential intruder can't gain access to these data. In this article we will discuss why you can't clear private data using memset() function.
Safe Clearing of Private Data
by Roman Fomichev
From the article:
So, both gcc and clang decided to optimize our code. Since the memory is freed after calling the memset() function, the compilers treat this call as irrelevant and delete it.
Using C++ Coroutines to simplify async UWP code--Eric Mittelette
The async pattern needed to write UWP apps (or simply "Universal apps") is not so easy to grasp, especially in C++. Eric from the Visual C++ team explains how the experimental Coroutines feature available in Visual Studio 2015 helps simplify async UWP code:
Using C++ Coroutines to simplify async UWP code
From the article:
C++ Coroutines can simplify your async code, and make the code easy to understand, write, and maintain...

Enhancing the C++ Basic Character Set with Standard Character Mappings
by Robert Douglas, Faisal Vali, Nate Wilson, Nevin Liber
Excerpt:
Languages evolve, as the means by which people best express their ideas. As this is the
domain of programming languages, it is up to us to make sure that C++ evolves in conjunction
with how people can best communicate their intents to machines and co-workers. Current
language has begun a transition to new forms of language.The world is additionally becoming far more social. In this new world, a competitive language
must be ready to embrace modern social forums with better support for the social paradigms of
the day. Unfortunately, C++ has a rather heavy syntax for expressing ideas. This is less of a
problem when armed with a keyboard and large monitors, but most devices these days are
smaller with shrinking keyboards, if any physical keyboard at all. This problem must be
mitigated, if C++ is to be an appealing language with the newest generation of developers.
