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.
Guidelines Support Library Review: string_span--Marius Bancila
What is a string_span?
Guidelines Support Library Review: string_span<T>
by Marius Bancila
From the article:
In a previous post I have introduced the
span<T>type from the Guidelines Support Library. This is a non-owning range of contiguous memory recommended to be used instead of pointers (and size counter) or standard containers (such asvectororarray).span<T>can be used withstrings, but the Guidelines Support Library provides a different span implementation for various types of strings. These string span types are available in thestring_span.hheader.
Aaargh! AAA – Right Good and Hygenic--Stephen Kelly
Always auto? Almost!
Aaargh! AAA – Right Good and Hygenic
by Stephen Kelly
From the article:
The idea of almost-always-
autohas been around for a few years and has fairly divided the C++ community. The effective result is that concrete types appear rarely in code, and variables are declared as ‘auto’ instead....
C++ in Competitive Programming: I/O--Marco Arena
In this new post on Competitive Programming I explain some common idioms to deal with input and output:

From the article:
Very rarely I had to switch to C functions (e.g. scanf) or turn off the synchronization between C++ streams and standard C streams...
Current Proposals for C++17
The start of a new series about the papers for the Jacksonville meeting:
Current Proposals for C++17

From the article:
There is a new batch of proposals for C++17, published for next weeks ISO C++ Committee meeting in Jacksonville, Florida. With way over 100 proposals...
RAII without exceptions--Eli Bendersky
Is RAII in C++ only possible with exceptions? Eli Bendersky clarifies the matter:
C++: RAII without exceptions
by Eli Bendersky
From the article:
this post is not about whether exceptions are good or bad. What it is about is RAII as a C++ dynamic resource management technique that stands on its own and is useful with or without exceptions. In particular, I want to explain why RAII is indeed useful even if you have exceptions disabled in your C++ code...
Revisiting QWidgets & data, refactoring and performance
A follow up on an older Blog post of mine:
Revisiting QWidgets & data, refactoring and performance
by Jens Weller
From the article:
My CMS project has grown quite a bit, and there are a few places where I think I should refactor the code. One of the larger ones is that TreeItem::get<T> returns a pointer instead of a reference. Another one is related to how the Qt UI application is acting when opening a new panel in the TabControl. There used to be a noticeable delay...
C++ in Competitive Programming: intro--Marco Arena
I'm starting a new series about how standard algorithms and containers help in solving competitive programming challenges. Here is an introduction:
