In the world of software engineering, there is a constant change. Anything we learn has a potential to get redundant just in a matter of years. A lot of languages, methodologies, techniques, tools, frameworks, libraries came in with a huge noise and went away silently. Very few things manage to live for a decade. However, there is one thing which has been there for more than half a century, and remained unchanged. It is the core of all operating systems, and also all compilers and interpreters of unexceptionally all programming languages, and it is also the father of almost all…

Before diving into topic, I want to begin with clarifying the terminology. Immutable data refers to data whose state cannot be modified after it has been created. Once an immutable object is created, its internal state remains constant throughout its lifetime. Any attempt to modify the object’s state results in the creation of a new object with the updated state, leaving the original object unchanged. In C#, you can define your data using either classes or structs. The choice between a class and a struct can influence the behaviour and performance of your application. Classes are reference types and structs…

In C#, the in parameter modifier is relatively a recent addition. It added in C# 7.2. The main point of in keyword is to pass a large value type to a method without copying the entire structure. Value types in C# are typically passed by value. This means that the entire thing is duplicated and handed off to the method. This may not be a big deal for small value types like int or bool. However, for larger value types, it can be quite expensive in terms of performance because it takes time and memory to take care of these…

The title could have also been “Don’t use unsafe code at all!” You will come to the same conclusion after reading this post, but still I gave a room for its usage. In C#, the usage of unsafe code is a topic of debate. On one side, it offers the potential for performance gains in specific scenarios. Yet the risks and complexities it introduces often outweigh its benefits. What is unsafe Unsafe code in C# refers to a block of code that uses pointers and allows direct memory manipulation, bypassing the .NET runtime’s type safety and security checks. This capability…

Containerization became one of the recent trends in software development technology, because of its advantages with deployment and scalability and it is not for the first time I am writing about dockerizing an app. No doubt, Docker practically is the only platform for containerization, and it provides developers a convenient method to bundle applications and their prerequisites into efficient containers. It also guarantees uniformity across very different environments. In this post, I will explore the steps involved in containerizing a React application using Docker, starting from the creation of a fundamental React component and concluding with its execution within a…

We often hear the terms “stateful” and “stateless”. Understanding these concepts has a critical importance since it is one of the most essential questions when designing and architecting software applications. In today’s blog post, I wanted to talk about these two very basic concepts. As the simplest definition, stateful application means an application which remembers the past, similarly, stateless application means an application which doesn’t remember the past. The state we have been talking about might be saved in a database, a file on the disk, a cookie in a browser etc. As an example, consider an e-commerce website. When…

Keeping things secure is the important part of any application. As entire internet going to cloud, Azure Active Directory (AD) is one of the best possible among one of two popular options. It helps manage who can use your app and what they can do. Let’s see how to set up Azure AD for a C# and Java Spring Boot backend, and a React frontend to make sure only the right people get in. First, go to the Azure portal and make a new Azure AD tenant if you don’t have one yet. Then, register your app in Azure AD.…

In software development, performance optimization is a crucial topic and one of the most effective ways to improve the performance is caching. However, caching is a double edged sword we need to very careful about when and how to use caching. So, we need to use right strategy in right place. Caching can be implemented at different levels, including memory, network, and CDN (Content Delivery Network) levels. Each level has a unique purpose and is suitable for different use cases. In this post, we will focus on memory-level caching which is simply storing the data in the memory of the…

Docker is a powerful tool that allows developers to package applications into containers. These containers can run on any system that has Docker installed, making it easier to deploy and run applications consistently across different environments. Containers are like lightweight, portable packages for your application, including everything it needs to run: code, runtime, libraries, and settings. I assume that you have already know what Docker is and also you have .NET and Docker installed on your machine. Don’t worry, just download and then next + next. For more details and official documentation, you can visit Docker’s official website and for…
