  • Working with MongoDB Using C#

    In this blog post I am going to show you how you can access and perform CRUD operation from C# based application against MongoDb.

  • RxJava : observeOn vs subscribeOn

    In one of my previous post, I have covered the basics of setting up RxJava based file processing application. In this blog post we will cover the two most important aspect of RxJava programming which is configuring observeOn & subscribeOn listeners. Before we get into the technical discussion of these concepts, lets quickly review the sample code snippet that we will be using for our discussion.

  • Why Blog??

    I have recently joined the local Toastmasters club in my office. The idea behind the Toastmasters club is to promote & improve public speaking by encouraging participants to give speeches either prepared lengthy speech lasting about 5 to 7 minutes or do an impromptu speech for about 2 minutes on any random topic. I can say with confidence that I have experienced drastic change in myself. I no longer shiver with fear of giving speech by facing large group of audience. Now this blog post is not going to be about the merits of Toastmasters instead I am going to use this post as placeholder for my next speech which is going to be on public writing aka Blogging.

  • RxJava - Getting Started : Part 1

    In this blog post, I am going to explain you the basics of RxJava by walking you through one of the sample application that I have built using RxJava framework. All that the application does is reads line from files, does some pre-processing with the read lines and then prints the output to the console. I will not get into the basics of RxJava or in general reactive programming fundamentals. If you are not familiar with the “Hello World” of reactive programming using RxJava then this might not be the suitable place for you to start. However if you know how to create an Observable and subscribe to it, then you will find this article not too difficult.
