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.

Using SDR to make .CSV files for Wireless Workbench
https://github.com/AD-Vega/rtl-power-fftw can help. This can be easily piped for various outputs and works with GNUPlot off the bat. Use this on an Android based SDR for foxhunting and Signal seeking.

how can I find other signals to listen to?
I like to use rrl_power_fftw

Frequency hopping driveway sensor?
You could use rtl_power_fftw to better record the wider band over a time period. This is similar to rtl_power from librtlsdr, but is more efficient and can dwell for as little as 100ms on any 2.4MHz window (24MHz done in 1 second, f.e.). You can then plot this data through GNUPlot to get visual representations.

Laptops with lowest RFI?
I have a rooted Android with an RTL-SDR attached, which I'd take with me if buying a new laptop. I'd sit near the laptop's on display with a stubby duck in the SDR and use rtl-power-fftw to rapid scan 27-1724MHz (fastest is 100ms dwell at 2.4MSps). Takes a minute or two and can be fed into GNUPlot to give you a pretty graph of signals seen. Do it at a low gain and any spikes you see are likely from those sources.

Passive signal collection?
Look into rtl_power_fftw. It can be run for hours on any host (including a Raspberry Pi) and the spectrum results examined later.

Rtl_power scanner logic
rtl_power_fftw is likely more well suited. It's multithreaded, so can sample IQ and process the data as it samples. It's also faster and uses libfftw for processing (faster and more accurate). Outputs more friendly, too. I use this in part with a signal heatmap project; https://www.reddit.com/r/RTLSDR/comments/ifer8j/progress_on_the_android_sdr_linuxdeploy_rtl_power/

Rtl_power scanner logic
I have something that does basically what you're talking about, in a fairly simplistic way, here https://github.com/MattMills/radiocapture-rf/blob/master/fft_based_scan.sh
