Below are my projects which I am currently developing or still maintaining.
Android binding and user interface for the tinc mesh VPN daemon which uses the standard Android API and does not require root privileges to work.
A static generator which turns a collection of tagged pictures into a searchable web gallery.
A LaTeX-Beamer split web viewer rendering separately slides and notes from double-width PDF presentations.
A web tool to record and play back audio clips.
A Pandoc AST filter rendering PlantUML code blocks into vector diagrams.
a feed processor
A simple Python framework for RSS feed processing, providing overridable classes for straightforward implementation of custom feed filters.
Past projects for which I lost interest can be found in the source repositories archive.
