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.

questions about getting into Lora?
Also, the messages will be extremely slow. On the low end, 300 baud (if you are close enough, 37kbps, but there are laws preventing full usage in some countries.). Not enough to send pictures in a reasonable amount of time. See also https://disaster.radio/

Post collapse communications
CollapseOS and disaster.radio?

Ask HN: What's with the DIY state of the art long-range Wi-Fi?
(btw. no affiliation here, just a happy customer)
Think about using fiber optics at least for longer fixed paths: a couple routers with SFP can provide a gigabit connection over several kilometers, and the fiber cable can be easily buried so that it's not easy to notice and doesn't hint the enemy that a transmitter is operating nearby like WiFi would certainly do.
For very slow and long distance communication, namely text messages, LoRa can be an option to which encryption can be added externally. All other considerations about radio transmission remain valid for LoRa too, however. You may find these links interesting:

The new RNode is a self-replicating, open and unrestricted digital long-range radio, that can be made by anyone with a 3D-printer and a few cheap parts bought online
This is extremely cool. Reminds me of https://disaster.radio/

Meshtastic / Disaster.radio / LoRa ?
Is anyone currently playing with, or is interested in creating a wireless network in the area to facilitate communication in the event of a disaster? There are these cheap, low power devices (about $20 or less) that can be programmed to communicate with others over very long distances, sending small messages, akin to SMS text message size. I was able to connect to people up to 23 miles away at my last house with this technology (via a Helium miner). The two most popular programs are Disaster.radio (https://disaster.radio/) and Meshtastic (https://meshtastic.org/). You basically put the device in an area where it has decent line-of-sight to someone else's device, and can chat to others via an Android/iPhone app that connects to the radio via bluetooth. This could be useful in general outdoor situations as well, where there is no cell phone service.

Check out https://disaster.radio/. I'd consider a lot of the parts they include in their system:

RNode is a free and open source "self-replicating" long-range radio for digital communications. Every device made contains all the blueprints, software and info needed to make more, along with basic software for setting up self-configuring, encrypted mesh networks for basic human communications.
Here is an example image of a completed device.
