Making things do stuff – Part 4
by Glennan Carnie
From the article:
In the last article we explored the design of a class to encapsulate a physical hardware device. In that article I deliberately ignored how the class would actually interact with the hardware.
In this article we explore the options available to us for accessing hardware and the consequences of those choices...

Pretty cool new feature of C++17!
Modern C++ Features – Class Template Argument Deduction
by Arne Mertz
From the article:
With C++17, we get class template argument deduction. It is based on template argument deduction for function templates and allows us to get rid of the need for clumsy make_XXX functions.

C++17 will make a few things more predictable and clarifies some of the usage.
C++17 in details: language clarifications
by Bartlomiej Filipek
From the article:
C++ specification is now clearer. We have now ways to assume Copy Ellison will happen, some orders of operations are well defined now, operator new is now aware of the alignment of a type and also exceptions are part of the function declaration.

Quick A: When it is assigned.
Recently on SO:
When is an rvalue evaluated?
s2binds to the expressions1 + s1, but is this evaluated at the times2is assignedYes.
And also woulds2hold memory for a temporary string?Precisely,
s2is bound to a temporarystd::string.
s1 + s1will produce a temporarystd::string, which will be bound to the references2(and its lifetime is extended to the lifetime of the reference). Thens2 += "Test";, performsoperator+=()ons2, i.e. the temporarystd::string.

How to do a pool?
A self-contained Pool in C++14
by Jens Weller
From the article:
During C++Now I started writing a small application, that plays around with dlibs face recognition features. More on this later, the program uses the QThreadPool, and some researched showed that calling dlib::get_frontal_face_detector() is a very expensive operation. So I decided to write a thread safe pool to share the face detection object between threads, only loading as many as needed. The main thread owns the pool which owns the detection objects...
