A: Yes, make_shared is your friend!
Recently on SO:
What happens when using make_shared
I'm interested if these two lines of code are the same:
shared_ptr<int> sp(new int(1)); // double allocation? shared_ptr<int> sp(make_shared<int>(1)); // just one allocation?If this is true could someone please explain why is it only one allocation in the second line?

Overload 122 is now available. It contains the following C++-related articles, and more:
Python and C++ are very different languages. Sergey Ignatchenko walks through things in Python that can confuse a C++ programmer
Using locks will slow down threaded code. Len Holgate demonstrates how an Activatable Object can reduce the time spent blocked.

How to handle HTTP and HTTPs requests in Qt
HTTP and HTTPs in Qt
by Jens Weller
From the article:
Last week I started to work on an old project again: My own feed reader. I found the code 2 weeks a go on an old USB Stick, and decided to refactor it into a useful state. This involved dealing with HTTP via QNetworkAccessManager.

You can do some great things when you have a reusable open-source C++ parser:
AST matchers and Clang refactoring tools
by Eli Bendersky
From the article:
Clang tooling sees lots of interest and development focus in the past few years. At last, we have a convenient, accurate, open-source and well supported framework for programmatically analyzing and refactoring C++ code; I find this very exciting.
A great outcome of this rapid pace of development is that new APIs and tools spring up all the time. For example, some time ago the Clang tooling developers figured out folks doing AST traversals have to write a lot of repetitive code to find interesting AST nodes, so they came up with a great new API called AST matchers, which I want to discuss here...

Quick A: By design, because function objects are expected to be nonstateful values.
Recently on SO:
Why doesn't std::sort accept comparator by reference?
The standard on
std::reference_wrapperexplains thatstd::sortnow acceptsstd::reference_wrapper, allowing one to pass a comparator by reference.Is there a reason
std::sortdidn't accept the comparator by reference in the first place?

Korban's C++11/14 feature overview book now has a Clang edition, in addition to VS2013 and GCC:
Clang Edition of the C++11/14 Rocks Book
by Alex Korban
From the announcement:
Do you use Clang to compile C++? Would you like to know all about the C++11 and C++14 language features it supports?
You can read about them in the new edition of my C++11/14 Rocks book tailored to Clang.
...
For those who have the GCC edition of the book: you’ll already be familiar with all the C++11 content as GCC also has full C++11 support. However, the Clang edition has full C++14 coverage instead of an overview.

Spotlight on Libraries Relying on C++14This article provides an overview of libraries in the wild using C++14 features in their implementations. While there aren't a lot of C++14-specific libraries available at this point, the article provides examples from functional style stream manipulation to typesafe string formatting.

At C++Now this and last year I recorded a short interview with Michael Wong:
A video interview with Michael Wong
The interview as a youtube playlist
by Jens Weller
From the Article:
I've started last year a video interview in Aspen - while at C++Now - with Michael Wong. This year I had the chance to finish the interview and I am now finally able to release it. Michael is a member of the C++ Committee for many years, he leads the Canadian delegation and also speaks for IBM at the C++ committee.
