An interview that went viral -- Rainer Grimm

An interview that went viral
by Rainer Grimm
From the article:
I gave the interview for the e-finance-blog "efinancialcareers". I essentially stated the following:
- C++ is heavily used in the finance industry, for game developers, and in the automotive industry.
- When you want to learn C++, start at least with C++11.
- C++ is often used to build infrastructure.
- C++ is too big to fall.
... In total, I got almost 2000 comments. Today, I want to present the main points about the final interview, because this is my motivation for writing articles, posts, and books, recording videos, and teaching and mentoring C++...
Top 10 bugs found in C++ projects in 2022
New Year is coming! It means, according to tradition, it's time to recall 10 of the most interesting warnings that PVS-Studio found during 2022.
Top 10 bugs found in C++ projects in 2022
by Vladislav Stolyarov
From the article:
Here the analyzer detected that a function, marked as noexcept, calls a function that throws an exception. If an exception arises from the nothrow function's body, the nothrow function calls std::terminate, and the program crashes. It could make sense to wrap the setName function in the function-try-block and process the exceptional situation there — or one could use something else instead of generating the exception.
libstdc++ gets C++20 chrono
Imagine Jonathan Wakely in a red suit with his helper elves, delivering presents:
libstdc++ gets C++20 <chrono>
As seen on Reddit:
It looks like Jonathan Wakely has just today contributed a huge amount of effort towards
<chrono>.He's added the time zones, leap seconds, all that good stuff.
He's even added GDB pretty printers for inevitable date time debugging!
And these features are supported in <format>, which libstdc++13 has, if you weren't already aware. He's also made many other various improvements. Lets give a round of applause to Jonathan Wakely!
Using modules in the big three compilers

Using modules in the big three compilers: a small experiment
From the article:
The goal of my experiment was to see how easy it is to write code that a) uses C++20 modules, b) can be compiled by GCC, Clang and MSVC without using conditional compilation, c) imports something from the standard library, d) exports at least one templated function, e) has a peculiarity that makes the module harder to find (in my case, the module is named b but the file that contains it is named a.cppm).
The experiment sort of succeeded...

The Strategy Pattern -- Rainer Grimm
A canonical example:
The Strategy Pattern
by Rainer Grimm
From the article:
Purpose: Defines a family of algorithms and encapsulates them in objects
Also known as: Policy
Use case:
- Different variations of an algorithm are needed
- The client does not need to know the algorithm
- The algorithm should be exchangeable at the run time of a program...

The Template Method -- Rainer Grimm
With or without actual templates:
The Template Method
by Rainer Grimm
From the article:
The key idea of the Template Method is easy to get. You define the skeleton of an algorithm that consists of a few typical steps. Implementation classes can only override the steps but cannot change the skeleton. The steps are often called hook methods...
