By bfilipek | Dec 28, 2018 12:29 PM | Tags: c++17

Just before Holiday Break, I've added a new chapter to my book:

How To Parallelise CSV Reader with C++17 - new chapter in C++17 in Detail

By Bartlomiej Filipek

From the new chapter:

In the new chapter, you’ll see how to build a tool that works on CSV files, parses lines into sales records and then performs calculations on the data. The code uses many C++17 features. You’ll see how easy it is to add parallel execution to selected algorithms and have a performance improvement across the whole application. In the end, we’ll discuss problems that we found along the way and possible future enhancements.

A brief introduction to Concepts – Part 1--Glennan Carnie

Useful new feature.

A brief introduction to Concepts – Part 1

by Glennan Carnie

From the article:

Concepts allow us to express constraints on template types with the goals of making generic code

  • Easier to use
  • Easier to debug
  • Easier to write

In this pair of articles we’ll look at the basics of Concepts, their syntax and usage.  To be open up-front:  this article is designed to get you started, not to make you an expert on Concepts or generic code...

CppCast Episode 180: Semantic Merge for C++ code, Plastic SCM and more on version control

By Jordi Mon Companys | Dec 21, 2018 07:18 AM | Tags: performance efficiency c++17 c++14

Episode 180 of CppCast the first podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Pablo Santos from Códice Software the company that develops a merge tool that parses and merges even refactored C++ code:

CppCast Episode 180: Semantic Merge for C++ code, Plastic SCM and more on version control

About the interviewee:

Prior to entering start-up mode to launch Plastic SCM back in 2005, Pablo worked as R&D engineer in fleet control software development (GMV, Spain) and later digital television software stack (Sony, Belgium). Then he moved to a project management position (GCC, Spain) leading the evolution of an ERP software package for industrial companies. During these years he became an expert in version control and software configuration management working as a consultant and participating in several events as a speaker. Pablo founded Codice SoftwaLogo-semantic-vertical-negative.pngre in 2005 and since then is focused on his role as chief engineer designing and developing Plastic SCM and SemanticMerge among other SCM products.

Did anybody consider adding a language pragma to C++?

By Adrien Hamelin | Dec 21, 2018 06:25 AM | Tags: community

Interesting question.

Did anybody consider adding a language pragma to C++?

From the article:

For people who don't know, language pragmas are the way that ghc (Glasgow Haskell Compiler) allows you to turn on and off language features. In C++, this would mean that I can write something like:

#language <no_c_style_cast>

And that would disable C-style cast for that source file. Don't you think that it would be useful to standardize this to allow people to willingly disable some old legacy C++ features in newer code?

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

By Adrien Hamelin | Dec 20, 2018 02:07 PM | Tags: community

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...
