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.

Tesla has the best navigation software in the business
Does Tesla even do their own routing? As far as I am aware they use https://github.com/valhalla/valhalla

Boost.Graph user survey
I use it to implement a solver for the Chinese Postman Problem for an open source routing engine named Valhalla (https://github.com/valhalla/valhalla/).

How to Learn Nix
Love the idea of a blog post like this. I tried something very similar a couple weeks ago on a c++ project, both in hopes it might lead to an improved user experience, and also for others struggling to figure it out.

Bolt v2... navigation cues lagging, auto start/stop finicky
Note that Wahoo doesn't implement their own routing, the Bolt is using OpenStreetMap and Valhalla (https://github.com/valhalla/valhalla) to do routing. That's probably a reason why bugs are never fixed, it's not their code.

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
