Google's internal C++ tips are going public:
Abseil Publishing Google's C++ "Tips of the Week"
By Tom Manshreck, Abseil and C++ Tech Writer
From the article:
Background: About five years ago, within Google we started publishing a series of C++ tips, about once a week, that became known as the “C++ Tips of the Week” (TotW). They became wildly successful, and we are still publishing them to this day (indicating that a language as rich as C++ will not deplete us of topics anytime soon).Not only do we discuss the finer points of the language, but in true “tip” fashion, offer our advice or design preferences. The collective set of C++ TotW has become a canon within Google itself, cited thousands of times per week in code reviews and internal mailing list discussions. Often they are cited by number, and some have become known simply as “totw/110” or “totw/77”.
We’ve decided to expose most of these tips to the Abseil development community, and the C++ community at large.

A friendly type predicate
by Andrzej Krzemieński
From the article:
This is a sequel to the previous post on writing a custom type predicate. One of the readers on Reddit made a very insightful observation. The user has implemented a type that she intends to use with our library, call it Calc. She passes it to the library function, and she gets the compiler error:
static assertion failed: X does not have a desired interfaceBut what is our type missing? In the previous post we were describing 3 constraints. A concept could have far more of them. The user has already made an effort to have Calc comply with the constraints, so there must be something tiny missing. Maybe there is a bug in the implementation of the predicate? But it is difficult to track what it is that the predicate does not like about our type. We could use some more specific information...

Many programmers know firsthand that C and C++ program builds very long. Someone solves this problem by sword-fighting at build time, someone is going to the kitchen to "grab some coffee". This article is for those who are tired of this, and who decided it is time to do something about it.
Speeding up the Build of C and C++ Projects
by Phillip Khandeliants
From the article:
If your operating system uses ELF format object files (Unix-like systems), you can replace the GNU ld linker with GNU gold. GNU gold comes with binutils starting from the version 2.19, and is activated by the flag -fuse-ld=gold. In CMake it can be activated, for example, by the following code.

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.

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)...
