Hi there!

My name is Rukshan, a wonderer, blogger, occasional coder and a health informatics guy.

I’m Rukshan Ranatunge, currently following my Master’s of Science degree in the field of Biomedical Informatics. I’m interested in digital health systems and achieving interoperability between digital health systems.

This is the place where I write about my musings in my everyday life, tutorials, adventures and misadventures, hot takes and everything in between. If you find my writing helpful, please leave a comment.

Latest musings

  • I was happy, sad, lost and lonely without a smartphone at the same time

    I haven’t posted on my blog for a long time, partly because I have been super busy with my personal and work life. I moved to Switzerland to work as a health informatics specialist for the Swiss Tropical and Public Health Institute, and moving to Switzerland in a very short period has been a change…

  • Why We Need Interoperability and HL7 FHIR

    I was lucky enough to attend the DHIS2 annual conference at the University of Oslo last week, where I was able to meet experts from all around the world in digital health to discuss not just DHIS2 but also FHIR and interoperability in general. When I describe my part in developing the national FHIR profiles…

  • Is It Time to Open Source SublimeText?

    Recently I had to do some text editing and was in need of a text editor that was better than Notepad, and with muscle memory, I went on and tried to download VSCodium. However, the download was like 100+ megabytes in size and since I was using a public internet connection that would make me…

  • How to Correctly Load Your Country in to Apache Superset

    TLDR Apache Superset is a free and open-core data analysis tool that offers a wide range of really neat features for a business. It’s a good piece of software where you don’t have the budget to spend on an expensive business intelligence tool. Sadly their documentation is not up to date, the questions and solutions…

  • Installing DHIS2 on a Windows Server

    Recently a college contacted me asking how they can install DHIS2 on a Windows server which they have just received on their premises. Since most tutorials available on the internet discuss installing DHIS2 on a server running a Linux distribution, he was finding it difficult to follow the steps outlined in those tutorials. I decided…

  • Running a Local HAPI FHIR Server For Testing HL7 FHIR Requests

    When implementing FHIR, a FHIR server is essential for validating and process incoming FHIR requests from clients. Also, it will be the place where you store your customized profiles, valuesets, and codesystems that is necessary for managing terminology. HAPI FHIR is the most popular FHIR server available at the moment and has been available for…

  • Installing Apache Superset Version 2 on Ubuntu Without Errors

    Apache Superset is a great free and open-source software released by the Apache foundation for advanced data visualization and exploration. Unlike proprietary tools for data visualization, Apache Superset adds value for an organization as free and open-source software. Once installed, you can create multiple dashboards with multiple varieties of charts, maps, etc, and connect multiple…

  • Codeberg a GitHub Alternative From Europe

    Recently I started migrating my note-taking from Notion to Obsidian. Obsidian does not offer free syncing between devices and you will have to manually set up a method to sync your notes, either by using something like Dropbox, Google Drive, or Git. So I thought it would be easier for me to set up a…

  • The rings of share – the unsolved problem of sharing

    Recently (last Saturday), I went to the Colombo Street Food Festival. It was a bit crowded for my liking but had awesome music and good beer. I snapped some photos of the event, recorded some clips of the music, and snapped some more photos with the others who I went to the festival with. I…

  • Medium and Google is not a good combination

    I know this is going to sound just like another complaint against Google, but I want my Google results to be better. Medium and Pinterest are two sources with a large footprint on Google. If you want to search for an image, Pinterest occupies the front page, they used to snatch most of the first…
