Enabling IT in Healthcare by simulating Patient Data

In the current times of pandemics and disease outbreaks, it is of paramount importance that we leverage software to treat diseases. One important aspect of healthcare is Patient Management. IT systems have to be developed which can support management at an enormous scale. Any development of such good software system requires data which is as realistic as possible but not real. There has to be a fine balance between privacy and enabling developers to anticipate the myriad health scenarios that may occur. Towards this initiative, healthcare industry has been standardizing around the HL7 (Health Level 7) protocol. The HL7 protocol itself has undergone transformation from pipe-based formats (v2.x) to JSON/XML based (FHIR) modern formats. FHIR is the future of HL7 messages and is being increasingly adopted. However given the slow nature and reluctance by healthcare providers to change or upgrade their systems, a majority of hospitals still use the HL7 2.3 format.

FHIR is a modern format. There are lots of tools available to simulate patient data in FHIR format including the wonderful open-source Synthea tool which runs through a fictional patients entire life journey creating fake encounters, observations and such. However to my surprise, there are not many tools which can generate data in v2.3 legacy format.

So I took this as an opportunity to create a tool of my own - MayaMaker. This is an open-source GPL-licensed tool which uses Synthea data and NHAPI library to introduce scheduling algorithms between a patient's encounters to create fake ADT (Admission, Discharge, Transfer) messages. One can generate messages for one encounter or all the encounters that a person may have in their lifetime. You can view the source code on Github or view the live demo site here - If you need to automate the message generation, there is an API available here -

Hope this tool is a small step in helping software professionals in healthcare industry and make the world a better place.

Integrating React with SonarQube using Azure DevOps Pipelines

In the world of automation, code quality is of paramount importance. SonarQube and Azure DevOps are two tools which solve this problem in a continuous and automated way. They play well for a majority of languages and frameworks. However, to make the integration work for React applications still remains a challenge. In this post we will explore how we can integrate a React application to SonarQube using Azure DevOps pipelines to continuously build and assess code quality. Creating the React Application Let's start at the beginning. We will use npx to create a Typescript based React app. Why Typescript? I find it easier to work and more maintainable owing to its strongly-typed behavior. You can very well follow this guide for jsx based applications too. We will use the fantastic Create-React-App (CRA) tool to create a React application called ' sonar-azuredevops-app '. > npx create-react-app sonar-azuredevops-app --template typescript Once the project creation is done, we

Creating a Smart Playlist

A few days earlier I was thinking that wouldn't it be nice if I had something which will automatically generate a playlist for me with no artists repeated. Also, it would be nice if I could block those artists which I really hate (like Himesh Reshammiya!). Since I couldn't find anything already available, I decided to code it myself. Here is the outcome -  This application is created entirely in .NET Framework 4/WPF and uses Windows Media Player Library as its source of information. So you have to keep your Windows Media Player Library updated for this to work. It is tested only on Windows 7/Vista. You can download it from here . UPDATE : You can download the Windows XP version of the application here . Please provide your feedback!

Bhagavad Gita Reader

Few days ago I had a heated argument with my friend about religion. Still fresh from watching " Religulous ", I was countering his every argument. Fed up, he asked me to read Bhagavad Gita and then tell him if I find anything wrong with it. Faced with the prospect of reading a book running into hundreds of pages, I asked him to keep it cool and let it go. He anyways went ahead and gifted me the holy book. Now I don't have the patience or passion to read such a thick religious book (yeah go ahead, judge me), I was thinking of a shortcut. That's when the idea of Bhagavad Gita Reader came into my mind. Snapshot - (Click for a larger view) This application divides Bhagavad Gita into chapters and verses. Then each verse and its translation is shown. There are no extra "interpretations to clutter up your mind." This application is built on WPF/.NET 4.0 with MVVM Light framework - A great framework with a very small learning curve as compared to Prism  albeit
