Hi, I'm Matthias

I am a founding partner of Feinheit AG and Die Bruchpiloten AG. Find me on GitHub, Mastodon, LinkedIn or by email.


Weeknotes (2023 week 6)


I made some progress learning Rust. I don’t have to look up each character and function and am slowly getting a feel for the language, unwrapping and the borrow checker, so that’s nice.

I don’t have a use for it for now, but we’ll see.

feincms3-data and data cycles

I added support for loading data with cyclic dependencies to feincms3-data. This is useful e.g. when having Django models where you have a ForeignKey("self") and you want to use feincms3-data to insert a new copy of some object and its dependencies.

Editing trees in the Django administration interface

I’m back to one of my favorite (not) activities which is making tree-shaped data editable in the Django administration panel. FeinCMS and later django-mptt augments the changelist with some drag drop behavior. There’s no undo functionality though so making errors is potentially really bad.

feincms3 uses a separate page for moving nodes around.

Now I’m working on a Preact-based project which also doesn’t use drag drop but which also allows inserting nodes, not just moving nodes around. I doubt I can make it reusable enough to make it useful for feincms3 but we’ll see.
