Since I keep forgetting which project is hosted where, here is a list of all(?) my open source projects as of 2018-10-06 with links to the pages where they are being hosted.
I have just released version 0.0.5 of my Denkzettel Companion tool. It is available from OSDN.
This version fixes a bug that prevented the program to start when the notes directory did not exist.
(Since nobody reported that problem, probably nobody but me has ever used the tool.)
Also, I have moved that project to OSDN now too.
