Project mention: .NET MAUI Is Coming to Linux and the Browser, Powered by Avalonia | news.ycombinator.com | 2025-11-11
> Blender: frontend Python, backend C++.
blender's frontend is pretty much exclusively C++? https://github.com/blender/blender/tree/main/source/blender/...
> Houdini: frontend Python(PyQt),
I would be infinitely surprised if Houdini's frontend wasn't also a majority C++. Likewise consider large apps such as Ardour, Krita, etc.

OpenStreetMap officially maintains 2 first-party raster tile server packages called mod_tile and Tirex. The rendering for these tools is powered by the open source Mapnik map generation library. Mapnik requires styles to be provided via an XML config, and a CSS-like language called CartoCSS was created by Mapbox that compiles down to Mapnik configs to make building these XML configs easier. CartoCSS was phased out by Mapbox starting in 2016 in favor of their vector tiles. Despite CartoCSS not receiving a commit since 2020 and the GitHub project being archived in 2024, the OpenStreetMap website still uses it for defining its Mapnik styles. A project called openstreetmap-carto maintains the stylesheets for the standard map layer on openstreetmap.org. To see more about how these pieces fit together, check the component overview page on the OSM wiki.
