D is an interesting language. For some reason, I have an emotional connection with this language and I believe that it is the subject of the biggest unfairness story in the history of software development. To me, it is the best programming language in the market for the reasons I am going to state below. However, this language is underestimated, underrated, and despised in the programming circles because it doesn’t have a strong backer. In this article I want to talk about, and give some credit to D, an underrated sibling of C++, Java and C#. The D programming language…

When designing systems, especially distributed systems, the flow of data and service requests must remain continuous. This brings us to an architectural design pattern called the Circuit Breaker. It comes from electronics. Simply, it is designed to stop the flow when something goes wrong. This prevents potential cascading failures in a system. Understanding the Circuit Breaker Pattern Imagine a scenario where a service relies heavily on another third-party service. However, that third-party service becomes slow or starts to fail at some point. Without any preventive measures, our service will keep making requests, waiting for timeouts, even getting stuck. This is…

Whenever a major improvement happens in web technology, whenever a new framework or a language is introduced in the web development market, PHP’s death is declared immediately. I have been witnessing a recent popular belief that PHP is nearing its end due to NodeJS becoming the new “darling” of the developer community. To me, this belief is a naive statement comes from lack of knowledge on the history of programming languages since the story of PHP is the greatest survival story of the entire computer science history. Over the years, many people have declared the death of PHP against a…

“Angular or React?” has been one of the most important questions in software development for the last decade. As a developer who had worked in full-stack fashion for a long time myself, my story of frontend started with Angular but had slightly moved towards React. Since I have actively participated projects in both, I wanted to write a comprehensive comparison between these two. Let’s explore the key aspects of each framework to help you make a decision, if you need to. Brief Overview: Developed and maintained by Facebook, React is a component-based library that deals mainly with the view layer…

A few weeks ago, we were discussing a problem with my team mates and a colleague raised a question about a very basic distributed remote caching problem which was about an application scaled out across multiple instances, managing how data is cached can become a significant challenge. Let me take the shortcut and directly jump into the problem. Consider a scenario where you have multiple instances doing the same job and you need to cache the result of a function which takes about 30 seconds. This function’s result needs to be cached to avoid redundant executions across different instances. The…

In a previous blog post, we discussed how to create real-time web applications using SignalR and React. If you have already gone through that, you would know the magic of SignalR in pushing instant updates, allowing users to receive data in real-time. In this post, we’re going to apply the same concept but with Angular. Setting Up the Server with SignalR Just as a quick refresher, SignalR provides an easy method to communicate between the server and the client in real-time. We start by installing the appropriate NuGet package: The hub, as described before, acts as the communication centre. Here’s…

Today’s topic is a quite popular one, a fuzzy word getting more and more popular once it used to be a niche architectural pattern only. When we think about building software, a lot of the time and energy is spent thinking about where and how it will run. Serverless architecture, also known as Function as a Service or FaaS, helps this to change. Instead of planning the environment to run, developers mainly write functions and let cloud providers like AWS or Azure handle where it runs. Briefly describing, Serverless is an architectural model where cloud providers fully manage code execution.…

For developers of my generation, C++ was the go-to language. It was everywhere, especially when you needed to write code that is fast, efficient and object oriented. C++ gave us the control we need to use every bit of performance and also extendable language to adapt modern programming techniques. We didn’t really think that one day there would be another language that could ever challenge C++ in what it did best. To me, C++ is still the king of all programming languages. However, Rust is not a rival to undermine. In this blog post we will see some details about…

Today, I want to talk about a new generation language which gains ground among developers. Go also popularly known as Golang, an open-source programming language created at Google by Robert Griesemer, Rob Pike, and Ken Thompson in 2007. It was specifically designed to improve programming productivity in the era of multicore processors, networked systems, and massive computation clusters. Go’s syntax is quite simple. It has a blood from C as C++, Java, C# etc. but they removed semi-columns as opposed to the traditional C type languages. A simple program to print “Hello, World!” in Go looks like: Since its beginning,…
