Microsoft Joins the MapLibre Sponsorship Program
At my day job we’re heavily invested in Leaflet for historical reasons, but toward the end of last year added Maplibre as a layer on top of it via the excellent https://github.com/maplibre/maplibre-gl-leaflet. This has allowed us to begin transitioning gradually instead of being forced to jump all at once.
It’s hard to beat the simplicity of Leaflet, but neither it nor OpenLayers can handle Mapbox Vector Tiles in a performant enough manner, so Maplibre is the future for us.

Which open source/free alternatives are there to open layers for rendering vector tiles in the browser?
On the Leaflet front, if you look at the plugins list, you'll see Leaflet.VectorGrid (made a long time ago by yours truly). And if you search for a bit, you'll find maplibre-gl-leaflet, which places a Maplibre instance inside a Leaflet map pane.

How The Post is replacing Mapbox with open source solutions
https://github.com/maplibre/maplibre-gl-leaflet exists!
It's not perfect, and you don't see the full benefit of a WebGL renderer, but if you want to keep using a Leaflet API, it's great.

Self Hosting a Google Maps Alternative with OpenStreetMap
Seems like MapTiler is maintaining an open source full stack vector alternative, and OpenLayers[0] looks good as well, so maybe it's time for legacy libraries to add vector support, or for users to switch libraries? There's even bindings from Maplibre GL to Leaflet [1].
I at least would find it interesting to see the two compared by someone other than me ;).

Geospatial Nix – create, use and deploy today
This is awesome. Such a great use case for nix.
I do a lot of geospatial processing in the cloud and I've been using Tippecanoe a lot to create vector tiles. It pairs well with PM Tiles for storing on the cloud. It seriously increases the web app performance for massive data sets. I queue these up with ECS tasks to process our json/csv/parquet input and create optimize vector tile outputs.

Tippecanoe would be a great addition to your nix packages. I've been thinking more and more about how Nix could fit into this pipeline.
Great work!

Self-Hosted Vector Tiles
I'm the author of a few of the tools mentioned in this post!
A convenient new development is instead of using tippecanoe -> go-pmtiles to create PMTiles archives, you can now output .pmtiles directly:
tippecanoe -o bks2.pmtiles mainroad.geojson ...
This is available in Tippecanoe (https://github.com/felt/tippecanoe) v2.17 and later.
Thanks to Felt (https://felt.com) for supporting this open source work.

How would you generalize a very high density vector map for various zoom levels ?
Things I have tried so far: - Just using native vector tile conversion as it involves feature simplification. Doesn't work since smallest feature just disappear, resulting in blank regions instead of "averaged" regions. - Using tippecanoe's built in features to drop/merge in densest zones. Results are disappointing because of unexpected (and too big) differences between each zoom level. - Rasterizing the map, sieving, then vectorizing with smoothing. Doesn't work because pixel information are mixed. I would need a way to rasterize while preserving the land-cover category (with some kind of majority filter ?), but haven't find a way to do this with any QGis built-in or plugin feature.

OpenStreepMap 2012 vs. 2022
Take a look at Tippecanoe, which is under active development again[0]. The original developer, Erica Fischer (who is wonderful to work with), has a fork[1] where new work is happening.
