The SoA Vector – Part 1: Optimizing the Traversal of a Collection--Sidney Congard
It's all for speed.
The SoA Vector – Part 1: Optimizing the Traversal of a Collection
by Sidney Congard
From the article:
I like C++ because it offers a good compromise between writing expressive and fast code. But, I discovered a problem where I didn’t know any way to hide the implementation detail away from its use: The “Structure of Arrays” (SoA) versus the “Array of Structures” (AoS) problem.
This is the first part of a series of two articles:
- what ‘SoA’ is about and what benefits it brings (part 1)
- how to implement an SoA vector in C++ (part 2)
So let’s see what those SoA and AoS are all about...
Boost 1.69.0
New release.
Boost 1.69.0
From the article:
Notes for non-Windows users
The Boost build system now supports visibilities. If you are building shared libraries, they will use hidden visibility by default. As a result Boost shared libraries become smaller, load faster and have less chances to get a symbol collision.See Boost.Build visibility and local-visibility for more info.
To disable that feature you can use use a command line ./b2 visibility=global to build...
C++Now 2019 Call for Submissions is Live
C++Now 2019 will be held in Aspen, May 5–10, 2017.
C++Now 2019 Call for Submissions
From the invitation:
The C++Now 2019 Call For Submissions is open! We invite all members of the C++ community, including first time submitters, to submit session proposals to the 8th annual C++Now Conference: C++Now 2018 (Aspen CO, USA, May 5 – 10, 2019).
C++Now builds upon the resounding success of previous BoostCon and C++Now conferences. We look forward to considering your proposals. You will be joining leading speakers from the entire C++ community in making C++Now 2018 better than ever.
CopperSpice: Linkage
New video on the CopperSpice YouTube Channel:
Linkage
by Barbara Geller and Ansel Sermersheim
About the video:
In this video, we cover the often overlooked topic of linkage and linkers. We talk about how translation units relate to object files, the various types of symbols, and debugging link errors. We also look at how anonymous namespaces interact with symbol linkage.

Using multi-stage containers for C++ development--Marc Goodner
An interesting method.
Using multi-stage containers for C++ development
by Marc Goodner
From the article:
Containers are a great tool for configuring reproducible build environments. It’s fairly easy to find Dockerfiles that provide various C++ environments. Unfortunately, it is hard to find guidance on how to use newer techniques like multi-stage builds. This post will show you how you can leverage the capabilities of multi-stage containers for your C++ development. This is relevant to anyone doing C++ development regardless what tools you are using...
Stop with the CTAD FUD!--Colby Pike
It's not cool.
Stop with the CTAD FUD!
by Colby Pike
From the article:
Among the catalog of features introduced by C++17, you’ll find a feature known as Class Template Argument Deduction, often shortened to “CTAD”. It was one of the largest language changes in C++17, and with it comes a new syntax and a new set of rules to understand.
It’s still very early in the game for CTAD, but we’re already seeing many strong opinions about it without seeing its widespread effect on codebases. In particular, we’re seeing a lot of Fear, Uncertainty, and Doubt about CTAD...

CppCast Episode 179: San Diego EWGI Trip Report with JF Bastien
by Rob Irving and Jason Turner
About the interviewee:
JF Bastien is the C++ lead for Apple's clang front-end, where he focuses on new language features, security, and optimizations. He’s an active participant in the C++ standards committee, where he chairs the Language Evolution Working Group Incubator (“oogie” for short). He previously worked on WebKit’s JavaScriptCore Just-in-Time compiler, on Chrome’s Portable Native Client, on a CPU's dynamic binary translator, and on flight simulators.
