Calendar and Time-Zones in C++20: Time of Day
By Rainer Grimm
From the article:
With C++20, the chrono library from C++11 becomes important additions. The most prominent ones are a calendar and time-zones support. But this is by far not all. C++20 gets new clocks, powerful formatting functionality for time durations, and a time of day type

The 3rd and last AMA planned for Meeting C++ 2020 is with Jason Turner and Rob Irving!
Jason Turner and Rob Irving join Meeting C++ 2020 for an shared AMA
by Jens Weller
From the article:
Jason and Rob are well known for being the Hosts of CppCast, but also have a live beyond this in the tech world. Jason is well known for his C++ weekly and recently published a book about C++ best practices. While Rob is an experienced software developer and team lead with a strong focus on C++, but also knows C#, Objective C, Java and Ruby.

It's no secret that compilers employ their own built-in static code analyzers, and those are developing as well. That's why we write articles every now and then to show that our static analyzer, PVS-Studio, can find bugs even inside compilers and that we are worth our salt.
Checking Clang 11 with PVS-Studio
by Andrey Karpov
From the article:
The programmer is using a modulo operation to get a random value of either 0 or 1. But the value 1 seems to confuse developers and make them write the classic anti-pattern in which the modulo operation is performed on 1 instead of 2. The X % 1 operation is meaningless as it always evaluates to 0.

The ACCU is now putting together its program, and they want you to speak on C++. The ACCU conference has strong C++ tracks, though it is not a C++-only conference. If you have something to share, check out their
Call for Papers
by the ACCU
About the conference:
The ACCU 2021 will be from 2021-03-10 to 2021-03-13, with a pre-conference workshops on 2021-03-09.
The ACCU 2021 will be an online event because of the COVID-19 pandemic.
Historically, ACCU has a lot of C++ and C content, and is proud of that: ACCU is the foremost annual conference for people interested in C++ and C, at least in and around the UK. But it is not just a C++ and C conference, ACCU is about programming in whatever language people are using, with whatever tools and processes people are using: D, Chapel, Java, Kotlin, C#, F#, Groovy, Rust, Go, Python, Ruby, Lisp, to name just a few programming languages about which there have been sessions at ACCU conferences. Git, Mercurial, CMake, Meson, TDD, BDD, allthese tools and techniques have been the focus of sessions at ACCU. The ACCU Conference is looking for sessions that will be interesting to people who create software.
The ACCU Conference is put on by ACCU (https://accu.org), but is open to anyone who wishes to be there either as a presenter or an attender.
The Call for Papers lasts for about 3 weeks and will close on Friday 2020-11-13 23:59 GMT

Somehow, we've happened to check most of the libraries making up a collection called "Awesome hpp". These are small header-only projects in C++. Hopefully, the information about the bugs we've found will help make the libraries better.

17 Smaller but Handy C++17 Features
by Bartlomiej Filipek
From the article:
When you see an article about new C++ features, most of the time you’ll have a description of major elements. Looking at C++17, there are a lot of posts (including articles from this blog) about structured bindings, filesystem, parallel algorithms, if constexpr, std::optional, std::variant… and other prominent C++17 additions.
But how about some smaller parts? Library or language improvements that didn’t require decades to standardise or violent “battles” at the ISO meetings.
In this article, I’ll show you 17 (plus a few extra!) smaller C++17 things that will improve your code...

More and More Utilities in C++20

From the article:
Today, I present a few utilities for calculating the midpoint of two values, check if a std::string starts or ends with a substring, and create callables with std::bind_front. These little utilities may not seem so little when you need them...

*nix systems assume you know what you're doing - even if you're doing something silly or dangerous. That's why you need to take extra precautions if you expect your code to be run as a privileged process.
Lay a strong foundation by writing secure C and C++ utilities
by G. Ann Campbell
From the article:
Libraries and system utilities form the foundations on which larger projects are built. So it's critical to make sure they, in particular, are secure. That's why we recently introduced five new rules for C++ and C to detect broken authentication and access control in *nix systems. The new rules fall into three categories: account validity, granting permissions, and changing directories.

The latest release of SonarLint for Visual Studio adds secondary locations to help you better understand the issues it raises in your C++ code. SonarLint is a free static analysis extension installable from the Visual Studio Marketplace.
Visualizing issues with secondary locations
By Duncan Pocklington
From the article:
All SonarLint issues specify a location in the code showing where the issue occurs. However, some of the more complex rules produce issues for which a single location is not enough to adequately explain why the issue has occurred. These more complex rules often identify additional locations in the code to help understand the problem. These additional locations are referred to as secondary locations.
