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.
JTS Topology Suite
- GitHub - locationtech/jts: The JTS Topology Suite is a Java library for creating and manipulating vector geometry.
-
JavaScript, Python, C#...
Well, JTS Topology Suite was first written in Java and then ported to other libraries: https://github.com/locationtech/jts#derivatives-ports-to-other-languages

The Open Source GraphHopper Routing Engine 8.0 Released
Well I think what he means is that we dropped the explicit support of Android and the example app with offline maps (Mapsforge), see this issue: https://github.com/graphhopper/graphhopper/issues/1940
But offline routing should still work on Android. But as you need JDK 1.8 support this will exclude a few older Android versions and devices, I think.

A software that will plan the most efficient routes for visiting address from my work location
Graphhopper. It has an Android client that uses its web service. You can also try out the web app.

Dangerous pedestrian crossing
This is now fixed and deployed. See the route here and the specific fixed examples here. Note that you can still find the dangerous spots via clicking the "stop" icon below the route information multiple times. But this is likely a result of the bad cycling infrastruture as cycle.travel contains these short dangerous parts too and if you do such longer routes for Germany it does not happen.

I Made A Way To Find Gravel Roads!
I'd suggest refactoring to use a self hosted version of Graphhopper (https://www.graphhopper.com/open-source/ - they have a docker image you can use and pass in an OSM file to build a graph on) or OpenRouteService to limit your cost exposure to google.

The New GraphHopper Maps Route Planner
Open Source. The routing server is open source too and geocoding too.

How The Post is replacing Mapbox with open source solutions
Valhalla is great (I've contributed a few patches and run it for a while)!

- API to get the name of the cities/locations/districts between two geographical points?

Self-hosted schedulers?
if you attached a geolocation to each meeting that should be possible. either using the google maps API or a self-hosted graphHopper instance

Map matching GPX -> GPX?
I just improved the documentation for the map matching a bit. Maybe this also helps a bit.
