A blog about my coding adventures
Introduction NASA’s Perseverance Mars Rover landing was a historic moment. First time, we saw those moments of a rover landing on the Mars. That event was huge for many people watching this on their screens and it will inspire us for years. Every single image we saw after this landing contains a new surprise and … Read more
Introduction In this post, I will be deploying and running a .NET Core, Angular and Postgres application on an Ubuntu VM running in azure cloud. This involves different tasks in different technologies to be done and I’ve previously written few posts about these different topics. In this post, I will combine all those learning so … Read more

Docker is changing how we distribute and install software and it is a very popular tool in many areas of software development as well. You don’t have to wait to use docker until you roll it out to your production environment. You can start with it straight away in your development workflow. I am using … Read more
Introduction I have previously written few posts about delegates, .NET Events, Events Args to show that similar to real world events, we can use this concept in our code and how useful they are in certain scenarios. In this post, we will see that those types are a good candidate for implementing observer pattern without … Read more
Introduction There is a famous quote by Jim Henson: “If you can’t beat them. Join them”. It’s possible to write code for years without deliberately using delegates. I say “deliberately” because we may have used them without realizing it. Knowing what these types represent makes reading code easier. Knowing how to use them adds some useful … Read more
Introduction In the previous post on Events, we talked about how we are surrounded by events and how useful they can be when writing loosely coupled code. We saw how we can define events, raise and finally handle events. If you haven’t already then I will suggest to read that post for the background and … Read more
Introduction Our physical world is surrounded by events e.g. Door Opened, Engine Started, Plane landed etc and we see events in the virtual world as well e.g. email received, friend-request sent, post liked etc. This is a very common concept, many programming languages support this and in this post we will see that how we … Read more
Introduction Object oriented programming is the one of the great grandfathers of modern software development techniques. Think about this. Term “Object-Oriented Programming” (OOP) was coined by Alan Kay in 1966 or 1967 while he was at grad school.! Lyndon B. Johnson was US president. Before email, cell phones and other tech goodies which we have … Read more
