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.

Just scrolled past a certain sarcastic Flatwittoid poast about not beïng able to see satellites in photographs. The whole frame of this represents *one single pixel of a high resolution* image, & the smiley represents a satellite. Details inside.
You realise you can write software yourself to interpret the signals from GPS satellites? Here's an open-source implementation.

Looking for someone with more experience in the flat earth debate that can review and expand my comment posted in the truckers subreddit.
Something I always enjoy pointing out is that GPS signals can be decoded by anybody, the source code is available here. Needless to say, there are references and calculations based on satellites all over it.

Calculating Position from Raw GPS Data (2017)
If you're interested in running some code, there's [1] which is fairly active, but as I recall is Linux only. There is also [2] which is a Matlab (or Octave) GNSS receiver implementation; quite well documented and informative. It's meant to be a companion to the author's book [3], which itself I found quite concise and approachable.

How do flat earthers think GPS works?
They like to pretend it is using towers or balloons or something else, none of them have ever coherently answered it with a viable way this could result in the GPS we can use from the device in our pocket. It also casually expands the circle of people involved in this conspiracy by thousands, to include all developers at Apple and other phone manufacturers that write/maintain the GPS components of their OS as well as contributors to open source projects like GNSS-SDR, an open-source software-defined GNSS receiver.

How do Flat Earthers explain satellite radio and GPS?
People also have to write the software to compute your location from these broadcasts, this means basically every company that has produced GPS receivers would have to be in on it. But there's an open source one, surprisingly nobody has raised an issue as to why it contains all this weird code that doesn't make sense if it's not coming from a satellite.

- Output argument X not assigned in the execution with Y function

I've scored my first HRPT images from NOAA on the 1.7GHz band! Here's how you can do it.
For the recording and aiming I used SDR#(with community plugins preferred) and the IF Recorder plugin, which feeds the recorded IQ data(.wav file) to LeanHRPT Demod which outputs the symbols received(as binary file). Then, LeanHRPT Decode converts those symbols to images! Finally I feed the produced image in a matlab script I that filters the salt&pepper noise with a Median kernel, and voila!
