Making things do stuff – Part 9
by Glennan Carnie
From the article:
As a final instalment in this series on hardware manipulation I thought I’d revisit read-only and write-only register types.

Trip Report: C++ Standards Meeting in Toronto, July 2017
by Botond Ballo
From the article:
A couple of weeks ago I attended a meeting of the ISO C++ Standards Committee (also known as WG21) in Toronto, Canada (which, incidentally, is where I’m based). This was the second committee meeting in 2017; you can find my reports on previous meetings here (November 2016, Issaquah) and here (February 2017, Kona). These reports, particularly the Kona one, provide useful context for this post.

Have you registered for CppCon 2017 in September? Don’t delay – Registration is open now.
While we wait for this year’s event, we’re featuring videos of some of the 100+ talks from CppCon 2016 for you to enjoy. Here is today’s feature:
Implementing `static` control flow in C++14
by Vittorio Romeo
Summary of the talk:
There has always been great interest in imperative compile-time control flow: as an example, consider all the existing `static_if` proposals and the recently accepted `constexpr_if` construct for C++17.
What if you were told that it is actually possible to implement imperative control flow in C++14?
In this tutorial, the implementation and design of a compile-time `static_if` branching construct and of a compile-time `static_for` iteration construct will be shown and analyzed. These constructs will then be compared to traditional solutions and upcoming C++17 features, examining advantages and drawbacks.

Examining applications that do not terminate on std::bad_alloc
by Sergey Zubkov
Summary of the talk:
System memory holds a special place in the hierarchy of program resources; its availability is the implied precondition for many innocuous lines of code, from std::string::substr() to passing std::function＜＞ by value. The ability to always create another object is ingrained in the OOP mindset so much that it is often said that immediate termination is the cleanest way to handle memory allocation failures in most situations. Nevertheless, C++, when consistently applying RAII, makes it possible to treat memory allocation exactly as any other resource acquisition.
To what degree do actual applications take advantage of that possibility and what responses to allocation failures are there in the wild? This presentation will examine over 300 open source projects that incorporate explicit handling for std::bad_alloc, examine the causes (it’s not always “out of memory”), response strategies (it’s more than just rollback), and related practical considerations.

In this article "No Bugs" Hare outlines the possibility to run C++ code in the major four web browsers.
(Not Really So) New Niche for C++: Browser!?
by "No Bugs" Hare
From the article:
For quite a long while, C++ had been losing popularity; for example, as reported in [Widman16], in 2016 it got 7% less of the listings on Dice.com compared with a year earlier; and according to [TIOBE17], from the C++ Golden Age in 2004 till 2017, the C++ share fell from ~17% to a measly 6%.
As all of us (as in, ‘hardcore C++ fans’) know , this has nothing to do with the deficiencies of C++; rather it is related to an observation that the time of downloadable clients (which was one of the main C++ strongholds) has changed into the time of browser-based clients – and all the attempts to get C++ onto browsers were sooo ugly (ActiveX, anyone?) that this didn’t really leave a chance to use C++ there.
Well, it seems that this tendency is already in the process of being reverted:
C++ can already run on all four major browsers – and moreover, it has several all-important advantages over JavaScript, too.
And this – not too surprisingly – is what this article is all about.
