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.

I wish language selection in OS and Browser were easier to access... but your browser does send a language header with your request, which generally matches your browser.
Location based is and can be a pain. I live in a border state and often get spanish versions of sites... I also follow a couple prominent youtubers who post english and foreign language content, so sometimes get results in those languages, that I don't read.
That said, using the default for the browser, and allowing override isn't a bad thing... I usually look for something that looks like a flag in the upper right, for language selection. And the few times I've written multi-language sites/apps that's the UX I prefer to use. I would default to browser/header, I would respond to the change event, and if the user selects a preference, set a cookie and use that first.
Again, I do wish it were easier to switch for the browser itself.
