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.

How The Post is replacing Mapbox with open source solutions
There's a lot to like about GDAL+Rasterio, although I've found having all HTTP requests go through GDAL's C API does result in some limitations on concurrency and multithreading. GDAL's configuration being based entirely on env vars also has its downsides: https://github.com/developmentseed/titiler/issues/186

Extending PostGIS with TiMVT/TiFeatures and PgSTAC
TiMVT and TiFeatures, along with TiTiler for raster services, complete a trio of python-FastAPI services. The current roadmap includes merging TiFeatures & TiMVT, the vector-based services, into a single project to reduce code redundancy.

Serverless GIS
COGs are great, but from my experience micro services like titiler don't support complex styling logic. Is there a possibility to create a serverless WMS service with complex styling requirements?

geotiff mosaic viewer / qgis?
Consider something like titiler if you want to serve the pile of geotiffs out to the web.

Configuring >100GB of imagery as raster tiles, TMS / WTMS, AWS S3 storage?
We were able to host 10gb six band rasters as well as 2cm RGB split into 100m tiles on S3 using COGS, mosaic.json and the TiTiler project which is powered by AWS lambda functions

Protomaps – A free and open source map of the world
I just used their pmtiles tool to grab a map of just the area around Half Moon Bay, south of San Francisco.
I grabbed the latest macOS Go binary from https://github.com/protomaps/go-pmtiles/releases
I found a rough bounding box using http://bboxfinder.com/#37.373977,-122.593346,37.570977,-122....
Then I ran this:

How The Post is replacing Mapbox with open source solutions
Yes, PMTiles is a tradeoff that isn't appropriate for transactional use cases. SQLite is pretty good for that already.
There is a throughput limit on S3 files of approximately 5500 GETs/sec per key. Bare archives on S3 is an appropriate choice for small-scale, zero maintenance deployments. If your application demands any thing close to that level of throughput, you're probably either:
* Serving individual tiles over the internet: you should use the CDN integration http://protomaps.com/docs/cdn ; most tile requests will be cached and only misses will interact with the S3 bottleneck.
* Bulk accessing a spatial subset of tiles: You shouldn't be requesting HTTP GETs for single tiles, but instead entire subsets of tiles with a single Range request made possible by the internal Hilbert curve ordering. This is still WIP here: https://github.com/protomaps/go-pmtiles/issues/31
