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.

Resource Scheduling
However, if you need to solve constraints etc., see: https://www.optaplanner.org/

Anything you wish there was an open source solution for?
Try looking for something built around Optaplanner - basically taking the end game of rostering and working backwards.

Seeking Advice and Collaboration for an Open-Source Worker Cooperative Platform Project
OptaPlanner takes some of the items tracked in tool like Odoo and creates plans based on them. I.E. how do you manage shifts while juggling multiple constraints (Jerry can only work weekends, Jeff can only work afternoons, Jim can work weekends but only on double time, etc.)

[Combinatorial Optimization] What is a good algorithm, or genre of algorithms that I should read up on for an optimization problem with a set of sets, where at least one element of each set is required?
There is a library out there called Optaplanner that is designed for optimization of NP complete problems. It is hard to tell if that is exactly what this is, but I think you should be able to use this regardless.

Searching for something to schedule IT helpdesk shifts
Just stumbled upon https://www.optaplanner.org. Looks very interesting but also really overkill.

Easy-to-use school scheduling software?
OptaPlanner - a generic scheduler.

Non profit Healthcare clinic looking for self hosted or cheap cloud alternative employee shift scheduling app?
OptaPlanner

Self-hosted schedulers?
I've never used it but it sounds like OptaPlanner may be a scheduler in the same vein?

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)!

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.
