Well-illustrated, and well-illustrated, gems:
C++ for Games: Performance, Allocations and Data Locality
by Sergey Ignatchenko
From the draft chapter:
One further thing to keep in mind with regards to 90-10 (or 70-30) rule is that even if only performance of 10% of the code matters, the rest of the code can still affect performance of critical 10% in a Pretty Bad Way :-( ...

C++ Performance: Common Wisdoms and Common "Wisdoms"
by Sergey Ignatchenko
From the draft chapter intro:
The opposite of a fact is falsehood, but the opposite of one profound truth may very well be another profound truth. — Niels Bohr
There are quite a few common wisdoms when it comes to C++ and games. As it always the case when facing a bunch of common wisdoms, some of them have their merits, some are obsolete-beyond-belief, and some are just taken from a very different context and are not really applicable. Let’s take a look at the most popular ones...

An interesting video to watch!
C++ Today
by Bjarne Stroustrup
Summary of the video:
During a short visit to College on 13 May 2016, Bjarne gave a talk describing what C++ is today (May 2016, C++14) and how it can be used well. He will focus on ISO standard C++ and the way it is developing.

News from Visual Studio:
May update for the C/C++ extension in Visual Studio Code
by Ankit Asthana
From the article:
We would like to thank all of you who have tried out the C/C++ extension in Visual Studio Code and have already provided
rich feedback on your experiences and filed issues and requests with us. We are working hard on incorporating your feedback
into the product. Continuing with our effort to make Visual Studio Code as the editor tool of choice for C++ developers with
this update of the C/C++ extension, we are introducing the following features:• Code formatting with clang-format
• Fuzzy Auto-Complete for C/C++ code
• Debugging on Windows for Cygwin/MinGW applications
• Console application debugging with GDB on the MacNow let’s dive into each one of these in more detail...

Lambdas from First Principles: A Whirlwind Tour of C++
by Arthur O'Dwyer
Summary of the talk:
Lambdas (even those mysterious generic lambdas) are just syntactic sugar atop constructs that are perfectly understandable when approached from the right direction.
We'll start with the implementation of C-style functions, then move to overloading, function templates, non-static member functions, C++11 lambdas, and then demystify C++14 generic ("auto") lambdas. Finally, we'll detour into the implementations of std::function and std::bind to show how they're different from lambdas.

The lightest feature rich C++ single header testing framework for unit tests and TDD
doctest 1.0.0 released!
From the release:
The doctest library is inspired by the
unittest {}functionality of the D programming language and Python's docstrings - tests can be considered a form of documentation and should be able to reside near the production code which they test.It is modeled after Catch which is currently the most popular and easy to use alternative for testing in C++

Quick A: Possibly.
Recently on SO:
Is final used for optimization in C++?
It can be.
An optimisation along these lines would relate to the "de-virtualization" of the virtual calls. This is not always immediately affected by the
finalof the class nor method. Albeit they offer help to determine this, the normal rules of the virtual functions and class hierarchy apply.If the compiler can determine that at runtime a particular method will always be called (e.g. given the OP example, with an automatic object), it could apply such an optimisation anyway, irrespective of whether the method is
finalor not.Optimisations fall under the as-if rule, that allow the compiler to apply any transformation so long as the observable behaviour is as-if the original code had been executed.

Let's talk about modules!
C++ Modules - Spring Update
by Gabriel Dos Reis
Abstract
“Modules” are a frequently requested and long-awaited feature by C++ programmers. The basic idea is a direct language support for (a) expressing the boundaries and dependencies of program components; (b) isolating source codes from macro vagaries; (c) scaling compile time, especially for large projects, given the ubiquity of “headers-only” template libraries; (d) spur innovation and deployment of semantics-aware developer tools. I will give an overview of the design points, goals, with emphasis on how modules address the four major problems mentioned above. I will also address standardization process and implementation issues

What's New in Visual C++ 2015 and Future Directions
by Steve Carroll • Ayman Shoukry
Summary of the talk:
In this talk, we'll discuss new features, optimizations, and scenarios in Visual Studio 2015. We'll cover new backend optimizations, improved build throughput, new productivity and diagnostics features, and give a detailed update on our conformance progress, as well as talk about cool new c++1y features that we are shipping from await to modules.
Visual Studio isn't just for Microsoft platform developers. We'll also demonstrate our latest cross platform C++ development features for Android and iOS. We'll also give a sneak peak at our work on combining the Clang frontend with our existing backend to bring Clang support for Windows to Visual Studio.

Episode 57 of CppCast the only podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Doug Binks from Enkisoftware to discuss Runtime Compile C++.
CppCast Episode 57: Runtime Compiled C++ with Doug Binks
by Rob Irving and Jason Turner
About the interviewee:
Doug Binks is programming the game Avoyd using Runtime Compiled C++, a technique he co-developed with industry friends; and enkiTS, a lightweight task scheduler.
An experienced game developer, Doug was previously Technical Lead of the Game Architecture Initiative at Intel. He has worked in the games industry in roles ranging from the R&D development manager at Crytek to head of studio at Strangelite, as well as lead programmer. An early interest in games development was sidetracked by a doctorate in Physics at Oxford University, and two post-doctoral posts as an academic researcher in experimental nonlinear pattern formation, specializing in fluid mechanics. His fondest childhood memories are of programming games in assembly on the ZX81.
