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...

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:
Garbage In, Garbage Out: Arguing about Undefined Behavior...
by Chandler Carruth
Summary of the talk:
There has been an overwhelming amount of tension in the programming world over the last year due to something that has become an expletive, a cursed and despised term, both obscene and profane: **undefined behavior**. All too often, this issue and the discussions surrounding it descend into unproductive territory without actually resolving anything.
In this talk, I'm going to try something very bold. I will try to utterly and completely do away with the use of the term "undefined behavior" in these discussions. And I will unquestionably fail. But in the process of failing, I will outline a framework for understanding the actual root issues that the software industry faces here, and try to give constructive and clear paths forward, both for programmers and the programming language.
And, with luck, I will avoid being joined on stage by any unruly nasal demons.

Making things do stuff – Part 3
by Glennan Carnie
From the article:
Previously, we’ve looked at the basics of hardware manipulation in C++ and applied that to a simple GPIO implementation.
In this article we’re going to have a look at encapsulating our code in a class and look at some of the design choices we have to make...

What's the status of reflection in C++?
An Introduction to Reflection in C++
by Jackie Kay
From the article:
Stop me if you’ve heard this one before. You are working on a messaging middleware, a game engine, a UI library, or any other large software project that has to deal with an ever-growing, ever-changing number of objects. These objects have many different qualities but can be grouped by their functionality: they can be sent across the network or collided with or rendered.
Because you are a good programmer who believes in the DRY principle, you want to write the “action” code that does the stuff on these objects without repetition, and plug in specific Message types or Renderable types into your generic pipeline at the appropriate places. It would be really nice to compose objects hierarchally: for example, if I had a widget class composed of several different renderable Rectangles, I want to be able to automatically generate the rendering code for my widget based on the existing rendering logic for its constituent shapes...

Some thoughts about final classes.
Final Classes

From the article:
A few days ago, a colleague asked me if it was wise to make every class a final class. Here is a more sophisticated answer than I could give at that time...

An issue we do not think often about:
Post-Conditions on Self-Move
by Eric Niebler
From the article:
TL;DR: In addition to the usual rule about move operations leaving the source object in a valid but unspecified state, we can add an additional guideline (not quite a rule, but follow it anyway):
Self-move assignment should “work” and leave the object in a valid but unspecified state.

C++ for embedded too!
Making things do stuff – Part 1
by Glennan Carnie
From the article:
C has long been the language of choice for smaller, microcontroller-based embedded systems; particularly for close-to-the-metal hardware manipulation.C++ was originally conceived with a bias towards systems programming; performance and efficiency being key design highlights. Traditionally, many of the advancements in compiler technology, optimisation, etc., had centred around generating code for PC-like platforms (Linux, Windows, etc). In the last few years C++ compiler support for microcontroller targets has advanced dramatically, to the point where Modern C++ is a increasingly attractive language for embedded systems development...
