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.

Database 101: How to Model Leaderboards for 1M Player's Game.
Then I decided to talk to my boss and ask him if I could work with the YARG guys and the condition was to create something cool enough to implement ScyllaDB (NoSQL Wide-column Database) since I'm working as a Developer Advocate there. You won't believe how the simplicity and scalability brought by ScyllaDB perfectly fit the needs of YARG.in!

Take Advantage of Git Rebase
What you say is impossible, we pretty successfully apply at ScyllaDB (see https://github.com/scylladb/scylladb/commits/master).
I'm not sure 100% of the commits compile & pass all tests - there may be some mistakes - but generally we're in a pretty good state, and the clean git log is being successfully used for bisecting.
If you want even larger scale - if I understand correctly, the Linux kernel practices a similar thing, which is where we got this practice from (ScyllaDB founders came from kernel development). And since Git was originally created to help developing Linux - that's where you want to look for good practices.
