New version of boost!
Boost 1.66 is out!
From the article:
New Libraries
- Beast: Portable HTTP, WebSocket, and network operations using only C++11 and Boost.Asio, from Vinnie Falco.
- CallableTraits: A spiritual successor to Boost.FunctionTypes, Boost.CallableTraits is a header-only C++11 library for the compile-time inspection and manipulation of all 'callable' types. Additional support for C++17 features, from Barrett Adair.
- Mp11: A C++11 metaprogramming library, from Peter Dimov.

Very convenient to create a development environment without hassles.
Clang 5 in a Docker container for C++17 development
by SolarianProgrammer
From the article:
If you want to try the new C++17, using Clang in a Docker container, you are in the right place. Running Clang in a container has the advantage that it is light on resources and won’t mess with your underlying OS. The last point is especially important if your host operating system is macOS, on which it is a really bad idea to directly install a binary Clang other than the one that comes with Xcode. I’ve tested the approach presented in this article on Windows 10, macOS High Sierra and Ubuntu Linux.

ACCU’s Overload journal of December 2017 is out. It contains the following C++ related articles.
Overload 142 is now available
From the journal:
Too Fast! Too slow! Too right!!
Many products over-promise. Frances Buontempo muses on how to get things just right. by Frances Buontempo

The first draft of "C++17 - The Complete Guide" is now available at
C++17 - The Complete Guide
by Nicolai M. Josuttis
About the guide:
Buy early, pay less, free updates.
This book uses a new publishing model: It is written incrementally and self-published. That way you can buy it even before it is complete and I have income while I am still writing it (note that I do C++ for a living).
Most of the new features are covered already in detail:
- All major new core language features
- The new library components (filesystem only by a few examples)
But there is still enough to do (see http://www.cppstd17.com/ for details).
All covered features went through significant review with awesome feedback and already have a lot of useful details including how they integrate with other features and discussing all the traps you should avoid.

Some template tricks.
Mixin Classes: The Yang of the CRTP
by Jonathan Boccara
From the article:
Now that we’re clear on how the CRTP works, let me share with you another technique involving templates that is complementary to the CRTP: Mixin classes. I learnt about mixin classes by watching Arthur O’Dwyer’s Template Normal Programming talk at CppCon (actually you can find them in the slides because they were skipped over during the presentation)...

Episode 130 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Dr. Greg Law from Undo to talk about the magic of reverse debugging and how it is becoming more widely known in the programming community.
CppCast Episode 130: Reverse Debugging with Greg Law
by Rob Irving and Jason Turner
About the interviewee:
Greg is the co-founder and CEO of Undo. He is a coder at heart, but likes to bridge the gap between the business and software worlds. (Sadly, these days most of Greg's coding is done on aeroplanes.)
Greg has 20 years’ experience in the software industry and has held development and management roles at companies including the pioneering British computer firm Acorn, as well as fast-growing start ups, NexWave and Solarflare. It was at Acorn that Greg met Julian and on evenings and weekends, they invented the core technology that would eventually become UndoDB. Greg left Solarflare in 2012 to lead Undo as CEO and has overseen the company as it transitioned from the shed in his back garden to a scalable award-winning business.
Greg holds a PhD from City University, London, that was nominated for the 2001 British Computer Society Distinguished Dissertation Award. He lives in Cambridge, UK with his wife and two children and in his spare time, catches up on email.

Red Hat at the ISO C++ Standards Meeting (November 2017): Parallelism and Concurrency
by Torvald Riegel
From the article:
Several Red Hat engineers attended the JTC1/SC22/WG21 C++ Standards Committee meetings in November 2017. This post focuses on the sessions of SG1, the study group on parallelism and concurrency. SG1 had a full schedule as usual, with Executors, Futures, and deferred reclamation mechanisms (e.g., RCU) being major discussion topics. We also started to track the state of proposals and topics we will need to discuss in a publicly accessible bug tracker...

This is about visual studio, but this is also about how the deprecated mechanisms work.
C++17 Feature Removals And Deprecations
by Stephan T. Lavavej
From the article:
Technology advances by inventing new ways of doing things and by discarding old ways. The C++ Standardization Committee is simultaneously adding new features and removing old features at a gradual pace, because we’ve discovered thoroughly better ways of writing code. While feature removals can be annoying, in the sense that programmers need to go change old codebases in order to make them conform to new Standards, they’re also important. Feature removals simplify the Core Language and Standard Library, avoiding the doom of accreting complexity forever. Additionally, removing old features makes it easier to read and write code. C++ will always be a language that offers programmers many ways to write something, but by taking away inferior techniques, it’s easier to choose one of the remaining techniques which are more modern...
