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.

openhaystack
- Beeper Mini will add SMS & RCS, other services, and FaceTime in ‘near future’
- OpenHaystack is a framework for tracking personal Bluetooth devices via Apple's massive Find My network. Use it to create your own tracking tags that you can append to physical objects (keyrings, backpacks, etc)

> For Find My, since they can even locate switched off phones
They can't. Find My is actually truly end-to-end encrypted, at least the version used for when a device is off (I'm not 100% sure how encrypted the self-reported version is for powered on iPhones with data).
Copy-pasting my summary about how Find My works from another comment in this post:
> The master private key used by the system is generated locally and never leaves your Apple devices in a state that anyone except your devices can read it.
> The master key is used to derive an AirTag specific private key which is provisioned to the AirTag and is in turn combined with an increasing counter which generates a third private key that's never stored anywhere. The ID broadcast is the public key of this third key. It changes every 30 minutes or 1 hour, I forget which.
> Other devices see this key, use it to encrypt their own location, and upload that encrypted blob along with the public key to Find My, and in order for Apple to even know which account the encrypted blob they can't decrypt belongs to I have to actually request the location of my AirTag by locally deriving the keypair it used for a certain point in time.
This has all been proven through [1] where they read the whitepaper (which I can't for the life of me find now but know exist because I've read it, or at least parts) and implemented OpenHaystack which proves Apple aren't lying about anything because if they did then OpenHaystack wouldn't work.

Kuba Wojciechowski: Google is working on a smart tracker similar to Apple's AirTag, codename "grogu"
Much more nuance than that. You can't just tap into the networks. More information here https://github.com/seemoo-lab/openhaystack

AirTags replacement
You can actually create your own, using Apple's "find my" network. See OpenHaystack
