The below are hobby projects I was doing strictly for fun, and I pursued them as long as I was interested. I use Google’s PaaS solution AppEngine for hosting them, so I could focus on the code and did not need to maintain or secure the underlying server infrastructure myself.

🚧 This page is very much under construction, maybe I will post some more, maybe not.

• dwarfgen — a webpage for generating dwarven names en masse

  In 2019 I reached a point where I needed a LOT of dwarven names and created the name generator I always dreamt about. It utilizes a math concept called formal grammar, a ruleset for generating names. I wrote a JavaScript library for generating names based on rulesets and created a ruleset for dwarven names.

• csalfa — a family tree tool

  I started this project as a kid back in the 90's when I was looking for a structure but future-proof format for preserving family tree info and old family photos. I came up with a tool which takes an XML description of the family and some family photos as input and generates a set of HTML pages for browsing the family tree. It was amazing to maintain this over decades, seeing how technologies come and go and everything changes. Both in the family and in IT.
