Maximum Drawdown in next-gen C++
by Marco Arena
From the article:
In finance, the drawdown is the measure of the decline from a historical peak in some series of data (e.g. price of a stock on a certain period of time)...

Quick A: in the order of declaration in the class.
Recently on SO:
Constructor initialization-list evaluation order
It depends on the order of member variable declaration in the class. So a_ will be the first one, then b_ will be the second one in your example.

C++ Core Guidelines: Improved Performance with Iostreams
by Rainer Grimm
From the article:
As easy as my title and the rules of the C++ core guidelines sound, getting more performance out of the Iostreams is no no-brainer...

Quick A: the result is the same as calling the function you're forwarding to directly.
Recently on SO:
Concise explanation of reference collapsing rules requested: (1) A& & -> A& , (2) A& && -> A& , (3) A&& & -> A& , and (4) A&& && -> A&&
The reference collapsing rules (save for A& & -> A&, which is C++98/03) exist for one reason: to allow perfect forwarding to work...

Episode 205 of CppCast the first podcast for C++ developers by C++ developers. In this episode Rob and Jason are joined by Robert Maynard from Kitware to discuss CMake and VTK.
CppCast Episode 205: CMake and VTK with Robert Maynard
by Rob Irving and Jason Turner
About the interviewee:
Robert Maynard is a principal engineer at Kitware and spends most of his time as a primary developer of VTK-m. VTK-m is a HPC toolkit of scientific visualization algorithms for highly concurrent processor and accelerator architectures. It uses a fine-grained concurrency model for data analysis and visualization algorithms allowing for seamless execution on GPU's or many-core CPUs.
When not working on VTK-m, Robert is either; writing CMake code, teaching CMake, or working to improve CMake.

More safety, maybe more speed.
Use constexpr for faster, smaller, and safer code
by Trail of Bits
From the article:
With the release of C++14, the standards committee strengthened one of the coolest modern features of C++: constexpr. Now, C++ developers can write constant expressions and force their evaluation at compile-time, rather than at every invocation by users. This results in faster execution, smaller executables and, surprisingly, safer code...

Simplify Your Code With Rocket Science: C++20’s Spaceship Operator
by Cameron DaCamara
From the article:
C++20 adds a new operator, affectionately dubbed the “spaceship” operator: <=>. There was a post awhile back by our very own Simon Brand detailing some information regarding this new operator along with some conceptual information about what it is and does. The goal of this post is to explore some concrete applications of this strange new operator and its associated counterpart, the operator== (yes it has been changed, for the better!), all while providing some guidelines for its use in everyday code.

At the moment, cloud CI systems are a highly-demanded service. In this article, we'll tell you how to integrate analysis of source code into a CI cloud platform with the tools that are already available in PVS-Studio. As an example we'll use the Travis CI service.
PVS-Studio in the Clouds - Running the Analysis on Travis CI
by Oleg Andreev
From the article:
Travis CI is a service for building and testing software that uses GitHub as a storage. Travis CI doesn't require changing of programming code for using the service. All settings are made in the file .travis.yml located in the root of the repository. We'll take LXC (Linux Containers) as a test project for PVS-Studio. It is a virtualization system at the operation system level for launching several instances of the Linux OS at one node. The project is small, but more than enough for demonstration.
