Making things do stuff – Part 6

by Glennan Carnie

From the article:

As code designers we tend to eschew specific ‘stove-pipe’ code in favour of reusable code elements.  Up until now we’ve been coding some very specific examples so it’s probably worth looking at some more generic solutions.

In this article we’ll look at building generic register manipulation classes (or, as one commenter referred to them, ‘register proxy’ classes).  Here, we’re really exploring code design rather than coding ‘mechanics’.  I’m using this to explore some factors like the balance between efficiency, performance and flexibility...

The Microsoft Visual C++ toolset offers numerous features that help you write secure, correct code:

Security Features in Microsoft Visual C++

Secure code starts before you write your first line of code. The compiler toolset can’t show you design defects that might lead to security exploits...

Making things do stuff – Part 5

by Glennan Carnie

From the article:

We’ve been looking at using C++ to manipulate I/O hardware.   Previously, we’ve looked at the fundamentals of hardware manipulation; and how to encapsulate these mechanisms into classes.  If you’ve not been following along I’d recommend reading the previous articles first before continuing.

This time we’ll explore a lesser-known feature of C++ and its application in hardware manipulation – placement new...

CppCon 2016: AAAARGH!? Adopting Almost Always Auto Reinforces Good Habits!?--Andy Bond

By Adrien Hamelin | Jun 28, 2017 08:56 AM | Tags: performance c++11

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:

AAAARGH!? Adopting Almost Always Auto Reinforces Good Habits!?

by Andy Bond

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Prominent members of the C++ community are advocating the "almost-always-auto" idiom, but there are understandable concerns from many about its implications. This case study will demonstrate how it may be applied in different situations, suggest ways to avoid performance penalties, introduce algorithms to minimize the "almost" part, and discuss the overall impact.

PVS-Studio 6.16 released

By Andrey Karpov | Jun 28, 2017 01:16 AM | Tags: tools static code analyzer errors devops

PVS-Studio is a static code analyzer that detects errors and potential vulnerabilities in the source code of programs written in C/C++/C#. Version 6.16 has obtained 11 new general analysis diagnostics.

PVS-Studio 6.16 released

by Andrey Karpov

About the release:

In a sense, this is a milestone for us. The thing is that we cannot add more numbers of general analysis warnings, otherwise they will concur with the numbers of micro-optimization diagnostics. It seemed to us that the list of 300 diagnostics was endless, but now it is over and we got to the point of 800, where we have micro-optimization diagnostics. In the next release we plan to resume numbering the general-analysis warnings with V1000. Download and enjoy the new version of PVS-Studio now by clicking here.

Merge the Concepts TS Working Draft into the C++20 working draft

by Ville Voutilainen

Excerpt:

The proposal is to merge the Concepts TS Working Draft into the C++20 Working Draft as is, and fix remaining issues, including design issues, before the publication of C++20.

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...

A unique_ptr pool --Jens Weller

Discussion regarding self contained unique_ptr pool implementation.

A unique_ptr pool

by Jens Weller

From the article:

A few weeks ago I wrote about a self-contained unique_ptr pool, which today I refactored into a more reuseable template. Reason is, that the pool class it self now needs to maintain two different kind of objects into their pools,  hence the actual pool code is best now factored out into a template.
