Marco Foco shows different solutions and tradeoffs to a dangling reference problem:
Optimizing return values
by Marco Foco
From the article:
As you can see, class C contains a function
get()which returns a reference to its internal state. In normal code, we must take care not to use this reference after our class has been destroyed...

Quick A: Yes.
Recently on SO:
Is the 'override' keyword just a check for a overriden virtual method?
That's indeed the idea. The point is that you are explicit about what you mean, so that an otherwise silent error can be diagnosed:
struct Base { virtual int foo() const; }; struct Derived : Base { virtual int foo() // whoops! { // ... } };The above code compiles, but is not what you may have meant (note the missing
const). If you said instead,virtual int foo() override, then you would get a compiler error that your function is not in fact overriding anything.

In a nutshell
The C++ Day 2016 is a special full-day event entirely dedicated to the C++ language, hosted in Florence (Italy), one of the most beautiful cities in the World. The event consists in technical sessions, interactive activities and networking.
Italian C++ professionals will speak (in Italian) on different C++ topics, including: C++17, Qt, API Design and Modern C++ for WinRT.
Other scheduled activities: C++ Unconference, C++ Coding Dojo, Template metaprogramming workshop.
Who should attend the C++ Day 2016?
This event is made by C++ professionals for C++ professionals, students and enthusiasts.
What can I find in the C++ Day 2016?
The agenda consists of 6x60' tech talks, 1x45' Q/A "Ask Us Everything" closing panel, 1x60' C++ Unconference, 1x60' C++ Coding Dojo, a workshop on Template Metaprogramming.
About the technical sessions, speakers will cover the following topics: C++17 for your daily job, Qt Graphics Stack, Data Oriented Design in C++, Kafka and High Performance Streaming, API Design, Modern C++ for the Windows Runtime (C++/WinRT).
The C++ Unconference is a 60' slot for people who want to open/join discussions on any C++ topic.
The C++ Coding Dojo is an interactive session where people will cooperate to solve programming challenges by wisely applying standard algorithms and containers.
The Template Metaprogramming Workshop will introduce templates and C++ metaprogramming. The workshop is free, however a separate registration is needed (details onto the registration page).
A 45' Q/A "Ask Us Everything" panel closes the event.
1/3 of the event will be spent for networking.

Brief trip report covering thoughts and "lessons learned" from the author's favorite talks and his own sessions.
trip report - CppCon 2016
By Vittorio Romeo
From the article:
CppCon 2016 ended yesterday - I had the pleasure of attending and presenting at this amazing conference again this year.
I'm really grateful to Jon Kalb, Bryce Lelbach, the conference staff, the speakers, my company and everyone else involved for making this possible.
In the same vein as my C++Now 2016 trip report, I wanted to share my thoughts regarding the talks I liked the most and regarding my sessions.

Analysis of a library development technique that allows users to decide whether or not to consume the library as "header-only".
opt-in header-only libraries
by Vittorio Romeo
From the article:
Libraries can be designed and implemented in order to allow users to choose between header-only usage, static linking or dynamic linking. [...] The main idea is to conditionally include .cpp files depending on a preprocessor macro, which can be defined during compilation. Functions also have to be conditionally decorated with the inline specifier.

Memories inspired by Herb Sutters Keynote at CppCon:
Subtle bugs through leaking
by Jens Weller
From the article:
Herb Sutters keynote on writing leak free code in C++ reminded me of seeing the opposite as a freelancer: code that has very obvious leaks. And it made me also think about what 'bugs' some of them caused.
