A description and implementation of a tradeoff for improving memory locality in fast-path code.
OutOfLine – A Memory-Locality Pattern for High Performance C++
By Patrick Moran
From the article:
OutOfLine is a tool that you can use to keep RAII, and move your cold members completely outside your object with zero space overhead.

How to break an ABI and keep your users happy
by Gennadiy Rozental
Summary of the talk:
Technical debt is the bane of most established libraries, whether it is standard library or boost or local library developed in house. Paying this debt is expensive and in many cases seems infeasible.
As a result of several (justified at the time) decisions Google accumulated serious technical debt in how we use std::string. This became a blocking issue in our effort to open source Google’s common libraries.
To fix this we needed to break libstdc++ std::string ABI. This is the story of how we survived it kept Google still running.

New video on the CopperSpice YouTube Channel:
Thread Safety
by Barbara Geller and Ansel Sermersheim
About the video:
This video covers concepts like thread safety, conditional thread safety, and reentrancy. We discuss the differences between these terms, the vital role that documentation plays in designing thread safe code, and how to effectively and clearly communicate the level of thread safety a particular function provides.

Learn the Exciting Features of The New C++ Standard with a new Book on C++
C++17 in Detail
by Bartlomiej Filipek
From the introduction:
C++17 was officially standardised in December 2017, giving us - developers - a wealth of new features to write better code.
This book describes all significant changes in the language and the Standard Library. What's more, it provides a lot of practical examples so you can quickly apply the knowledge to your code.

Over the past week, we ran our second global C++ developer survey, this time focusing on C++ use in cloud-related workloads.
Thank you to everyone who responded. As promised, here is a public summary of the results:
CppDevSurvey-2018-08-cloud-summary.pdf
This summary has now been forwarded to the C++ standards committee, along with the full text of your write-in answers. Your feedback will be very helpful, and thank you again for your participation!

My Little Object File: How Linkers Implement C++
by Michael Spencer
Summary of the talk:
Ever wonder how the linker turns your compiled C++ code into an executable file? Why the One Definition Rule exists? Or why your debug builds are so large? In this talk we'll take a deep dive and follow the story of our three adventurers, ELF, MachO, and COFF as they make their way out of Objectville carrying C++ translation units on their backs as they venture to become executables. We'll see as they make their way through the tangled forests of name mangling, climb the cliffs of thread local storage, and wade through the bogs of debug info. We'll see how they mostly follow the same path, but each approach the journey in their own way.
We'll also see that becoming an executable is not quite the end of their journey, as the dynamic linker awaits to bring them to yet a higher plane of existence as complete C++ programs running on a machine.

ACCU’s Overload journal of August 2018 is out. It contains the following C++ related articles.
Overload 146 is now available
From the journal:
Should I Lead by Example?
Stuck on a problem? Frances Buontempo considers where to turn to for inspiration.Cache-Line Aware Data Structures.
Structuring your program to consider memory can improve performance. Wesley Maness and Richard Reich demonstrate this with a producer-consumer queue.miso: Micro Signal/Slot Implementation.
The Observer pattern has many existing implementations. Deák Ferenc presents a new implementation using modern C++ techniques.(Re)Actor Allocation at 15 CPU Cycles.
(Re)Actor serialisation requires an allocator. Sergey Ignatchenko, Dmytro Ivanchykhin and Marcos Bracco pare malloc/free down to 15 CPU cycles.How to Write a Programming Language: Part 2, The Parser.
We’ve got our tokens: now we need to knit them together into trees. Andy Balaam continues writing a programming language with the parser.Compile-time Data Structures in C++17: Part 1, Set of Types.
Compile time data structures can speed things up at runtime. Bronek Kozicki details an implementation of a compile time set.

CLion 2018.2 brought compilation database project format support. And it's more useful already than you may realize, as nowadays an increasing number of build systems allows generating comp db out of them. Typical example is Makefiles!
Working with Makefiles in CLion using Compilation DB
by Phil Nash
From the article:
Now that CLion can open Compilation DB JSON files it means it can effectively understand projects from many more build systems. This gives CLion full code-completion, static analysis, navigation and even refactoring on such projects. For 2018.2 we don’t yet have build (except for individual files) or debug capabilities – but these are planned for an upcoming release. To see just how useful this is, we’ll work through a couple of examples.

Sourcetrail is a cross-platform visual source explorer based on Clang libTooling
Sourcetrail 2018.3 released
by Eberhard Gräther
From the article:
Sourcetrail 2018.3 brings new usability features for faster source code exploration. Users can continue to browse while reindexing in the background. A graph legend and new node actions have been added to the graph visualization. The code view was extended with a local reference navigation. Project setup now supports Sonargraph and Code::Blocks project import.
