Memory orderings for multi thread programming in C++ — Introduction As many know, since C++11, std::atomic<T> was introduced as a part of the standard library. Probably the most obvious part of the functionality is that each instantiated type of std::atomic<T> can be atomically operated on from different threads without causing any data race. But also, there is another aspect of…

If you’ve ever used a command line user interface on Unix-like operating system, you’ve probably encountered Unix commands. These are the instructions that let you control your system from the command line, without any graphical interface. They are powerful, versatile, and sometimes intimidating. But what if you could use Unix…

A Step-by-Step with example If you have a website hosted on AWS EC2 and you want to create a subdomain for it, you might think that you need to launch another EC2 instance and assign it a different IP address. However, there is a simpler and more cost-effective way to…

In modern computer systems, parallel processing is a common technique used to improve performance. However, there are several challenges to achieving efficient parallelism, one of which is false sharing. False sharing occurs when threads running on different cores of a processor access different variables that happen to share the same…

Classic AUTOSAR (AUTomotive Open System ARchitecture) is a software architecture framework that is widely used in the automotive industry to develop complex, safety-critical software systems. The goal of Classic AUTOSAR is to provide a standardized framework for developing automotive software that is modular, scalable, and portable across different hardware platforms. RTE (Run-Time Environment) Layer

In this post, we explored the use of std::visit in C++, which is a powerful utility that enables us to apply different functions to a variant object based on its current type. std::visit can be useful in scenarios where we need to handle variant objects with multiple possible types, such…

add_subdirectory vs include, function vs macro in CMake — Introduction As you may already know, CMake is a popular open source tool that manages the build process of software. With CMake, you can define variables along with a set of directives and instructions to describe your project processes (building, testing, packaging etc). You can consider the variables in CMake like…

Introduction of the popular meta-programming pattern — Introduction Templates are a useful feature with which we can define a generic function or a generic class that can be used with different types. Among all other cool things you can do with Templates, there is a popular templates technique called “detection idiom”. Detection idiom is a kind of pattern…
