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.

Friends don't let friends export to CSV
That's why I'm working on the GeoParquet spec [0]! It gives you both compression-by-default and super fast reads and writes! So it's usually as small as gzipped CSV, if not smaller, while being faster to read and write than GeoPackage.
Try using `GeoDataFrame.to_parquet` and `GeoPandas.read_parquet`

Postgres and Parquet in the Data Lke
> "Generating Parquet"
It is also useful for moving data from Postgres to BigQuery! ( batch load )

Thanks for the "ogr2ogr" trick! :-)
I hope the next blog post will be about GeoParquet and storing complex geometries in parquet format :-)

Beginner Questions about MapBox GL JS
This is definitely possible. A very common use case is publishing custom vector tiles to Mapbox, but since you want to host the tileset itself on your own server, you can use something like tilelive to do so. It's easy to create your own custom .mbtiles with Mapbox Studio, but it's an open specification, so feel free to create your own from arbitrary geographic data.

SQLite 3.39.2
> I once experimented with using SQLite as a file store for small images
Mapbox productionized this with their MBTiles [0] format, to store millions of small vector or raster map tiles in an SQLite database. Much easier to work with than millions of images on disk.
