The Annihilation of Conceptual Integrity by Tony DaSilva

A commentary on the C++17 directions being discussed today at the ISO C++ meeting in Kansas, USA:

The Annihilation of Conceptual Integrity

by Tony DaSilva

From the article:

When a large group or committee is tasked with designing a complex system from scratch, or evolving an existing one, I always think of these timeless quotes from Fred Brooks: ... “Who advocates ... for the product itself -- its conceptual integrity, its efficiency, its economy, its robustness? Often, no one.” – Fred Brooks

... Like all the other C++ committee members, Bjarne is a really, really, smart guy. For the decades that I’ve followed his efforts to evolve and improve the language, Bjarne has always expressed empathy for "the little people"; the 99% (of which I am a card-carrying member).
In a world in which the top 1% doesn’t seem to [care] about the remaining 99%, it’s always refreshing to encounter a 1 percenter who cares deeply about the other 99 percenters. And THAT, my dear reader, is what has always endeared Mr. Bjarne Stroustrup to me....

Binary literals and digit separators--Marius Bancila

The title says it all:

Binary literals and digit separators

by Marius Bancila

From the article:

The C++14 standard provides two new small features to the language: binary literals and digit separators. They are already available in Clang 3.4 and GCC 4.9 and now Visual Studio 2015 RC has implemented them. They may not be something you can’t leave without, but sometimes it’s convenient to have them. Let’s have a look...

5 awesome C++ libraries we use--Edouard

An interesting post on interesting librairies:

5 awesome C++ libraries we use

by Edouard

From the article:

This is an opinionated post about five libraries we use in the production code of quasardb.

We of course use many more great libraries (for example Boost.ASIO which is not listed here). Maybe those five libraries are not the most important, but I felt they deserved some special highlight as they are not so well-known or understood...

CppCon 2014 Lock-Free Programming (or, Juggling Razor Blades), Part II--Herb Sutter

By Adrien Hamelin | May 4, 2015 07:59 AM | Tags: performance efficiency

While we wait for CppCon 2015 in September, we’re featuring videos of some of the 100+ talks from CppCon 2014. Here is today’s feature:

Lock-Free Programming (or, Juggling Razor Blades), Part II

by Herb Sutter

(watch on YouTube) (watch on Channel 9)

Summary of the talk:

Example-driven talk on how to design and write lock-free algorithms and data structures using C++ atomic -- something that can look deceptively simple, but contains very deep topics. (Important note: This is not the same as my "atomic Weapons" talk; that talk was about the "what they are and why" of the C++ memory model and atomics, and did not cover how to actually use atomics to implement highly concurrent algorithms and data structures.)

Bringing Clang to Windows -- Raman Sharma

Also announced this week:

Bringing Clang to Windows

by Raman Sharma

From the article:

What if you could use a single compiler for your cross-platform code irrespective of what platform you target? ...

This is now possible with the work we have done. What this enables is a scenario in which you compile ... (2) using Clang and ... the Visual C++ back-end (We call it C2).  All of this while still enjoying the rich end-to-end developer experience within Visual Studio.

Stroustrup: Thoughts on C++17 -- An Interview -- Sergio De Simone, InfoQ

By Blog Staff | Apr 30, 2015 08:49 PM | Tags: None

Yesterday, Bjarne Stroustrup posted a draft note of his thoughts about the next C++ standard currently expect in 2017. In the following interview, Stroustrup answers further questions about his note:

Stroustrup: Thoughts on C++17 -- An Interview

by Sergio De Simone, InfoQ

From the article:

... Look inside most critical systems and gadgets and you’ll find some C++ inside. That, and being able to help science in a small way, through its software systems, motivates me. C++ is a tool meant to be used for building important artifacts.

Template Code Bloat Revisited -- Jason Turner

By Jason Turner | Apr 30, 2015 11:26 AM | Tags: performance

Jason Turner discusses in his recent article the size of instantiated template code.

Template Code Bloat Revisited Smaller Makeshared

by Jason Turner

From the article:

Back in 2008 I wrote an article on template code bloat. In that article I concluded that the use of templates does not necessarily cause your binary code to bloat and may actually result in smaller code!

However, after spending the last few months optimizing and evaluating ChaiScript I've learned that the misuse of templates, particularly when inheritance is involved, can have a huge impact on code size.
