That's an ambitious plan for sure! I also recommend the demos&drinks event, you can learn a lot of stuff you don't even have an idea you wanted to know about before you see it :) . See you there!

1) Download and install docker

2) Run this code in terminal

docker run --rm --name iris-demo -d -p 9090:52773 -e IRIS_USERNAME=demo -e IRIS_PASSWORD=demo intersystemsdc/irishealth-community:latest

3) Open browser at http://localhost:9090/csp/sys/UtilHome.csp and use VSCode to connect to the same host/port

Regarding SQL Server setup, you'll have to ask on SQL Server forum

I'm with Tim on this one, it's OK to create something like https://sergeinator.com for fun and giggles or use is as a prototyping tool instead of MS Paint, but I would not let this code anywhere near production.
