Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Anatomy of a MapServer: how to leverage and visualize your geographical data
I am a novice at GIS and mapping but when I got started I thought a map/tile server was the only way to build mapping webapps.
But, in my admittedly simple application PMTiles can cover a lot of my visualization use cases with a thing Django app doing GEOJson for interactive stuff.

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!

Serverless maps at 1/700 the cost of Google Maps API
The thing being discussed is designed for cloud, so I think self managed is a better description?

Self hosting pmtiles is straightforward also, make a file available to a server that supports range requests:

How The Post is replacing Mapbox with open source solutions
It might've just been this: https://github.com/protomaps/PMTiles/tree/main/serverless/aws
There isn't a tool to do that right now. It could be a fit in either https://github.com/protomaps/go-pmtiles or https://github.com/protomaps/PMTiles/tree/main/python - the Go program is faster and more production ready at this point. I imagine if folders are working for you the quantity of tiles doesn't number into the millions, so the Python program might be sufficient.
Feel free to open an issue.

Host your own OpenStreetMap Map Tiles
For the next revision of the JS decoder I'm including `fflate` as a dependency so clients can decompress gzipped tile data using JavaScript.

Ask HN: What happened to flatbuffers? Are they being used?
FlatGeoBuf [1] is an encoding for geographic data (vector features, i.e. points lines polygons and so on) written around flatbuffers that is increasingly well supported in geospatial software (GDAL, MapServer) and people reporting some experiments and demos on the @flatgeobuf Twitter.
