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.

SDR over Ethernet - Anyone tried it?
A network protocol called rtl_tcp that has been ported to rsp_tcp by the guys at SDRPlay in order to increase the IQ bandwidth from 8 to 14 bits to get the most from their SDRs. SDRPlay has provided a rsp_tcp server app/image that can be run on various hosts including RPi. Your RSPxx SDR connects to the RPi via USB and the RPi connects to your local network via Ethernet or Wi-Fi. Any network client application that supports rsp_tcp/rtl_tcp (including SDRUno) can connect to the RPi and use the SDR just as if it was connected via USB. This not only allows you to use your SDR from potentially anywhere you have a computer, it also allows you to minimize the distance between the SDR and the antenna(s). In theory you could even run Ethernet cable right up to the antenna.

What's a good Linux-compatible multipurpose decoder of RF signals?
For remote-location of an RTL dongle using Raspberry Pi or similar, which linux or windows clients can connect to over wifi or ethernet, there is rtl_sdr

How does sample rate work in an sdr
Hmm. I'd check out the RTL-SDR Sourcecode, in particular rtl-test, and manpage. This tool lets you calculates the PPM error of your dongle.

Raspberry Pi controlled radio telescope.
Not sure if it’s exactly what you want, but you can control GQRX over TCP. If you want more granular control, you can use the rtl-sdr library to process your desired signal. In my opinion it’s a bit low level for your project so using its Python wrapper, PyRtlSdr so you can get most of the rtl-sdr functionality while using Python’s networking.

H Line observations and question
In case anyone's wondering, Virgo detects and automatically takes care of slope correction using virgo.plot(slope_correction=True). If anyone's curious to integrate this particular utility into their own software, the source code for the operation can be found here.

Raspberry Pi Noise Above 1 GHz
My solution to suppressing those was to build a Faraday cage, and put it under the dish for additional shielding. You may also try calibrating and getting rid of some of these narrow spikes (e.g. with https://github.com/0xCoto/Virgo) if having the RPI isolated from the antenna is not a possibility.
