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.

Gradient-Free-Optimizers A collection of modern optimization methods in Python
I would be very disappointed if that were the case.. no, it looks like it’s set up to capture variance. The BO algo wraps an “Expected Improvement Optimizer”:
https://github.com/SimonBlanke/Gradient-Free-Optimizers/blob...
Which selects new points based on both the model’s mean estimate and its variance. See around line 58

Flipper Zero: Multi-Tool Device for Geeks
>> or somewhat expensive and complex SDR
I don’t think that’s as accurate today as it used to be.
On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.
More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.
On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.
Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh
I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.

What is your favorite thing to do on a flipper zero? I’m getting mine in a few days!!!
you should check out Universal Radio Hacker

Analysis tools?!?
Check out URH.

Any methods of making .wav recordings from an RTL-SDR in SDR# usable on the Flipper?
URH can read flipperzero sub files and can export from wav to sub... https://github.com/jopohl/urh

Repeating weirdness on 1897MHz, strong signal with weird side swirls. Australia, so this range is for DECT, but it's not, is it? Captured on 60m of speaker wire, maybe that's why it's so odd?
Throw the recording at UniversalRadioHacker and see what it does with it!

CubicSDR with RTL2832U cannot set 434.650MHz sample rate
I dont have much knowledge on decoding a signal from scratch but try URH - universal radio hacker here. It might be able to do what you need.

I can stream anything on a radio frequency
It's useful for transmitting digital RF signals to control household stuff, eg. ceiling fans or whatever. You'd want to also look into rtl-sdr and Universal Radio Hacker.

Linux: software: auto detect digital modulation type.
Tried tool https://github.com/jopohl/urh and it does not get too much information. I am expecting to find something similar to wireshark - it can detect protocols in traffic and highligh different kind of fields in packet headers.
