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.

Network Instrumentation and TCP File Descriptor Hijacking
> What's the performance hit for doing this?
So I want to be clear. This work is very much in the "fantasy" stage. I haven't ran this at scale, and there is a lot I would do before I blindly rolled something like this out. As far performance impact, it obviously would depend on how it's implemented however I think a reasonable amount of "tracer packets" being sent out every 15 seconds or so to each hop shouldn't be too disruptive to the network, or to the host machine issuing the request. In other words if you take the `ptrace(2)` concern out of the equation (this is the big one in my mind) its going to be negligible.
> And, the rootkit question, how would eBPF notice you doing this?
I suppose it would depend on what your strategy with eBPF is and where you were looking. Reminding yourself that the pidfd_getfd and pidfd_open functions are system calls, I think any modern Linux auditing system would see something like this "a mile away".
In other words, I don't see somebody using this tactic to steal FDs in production without quickly alerting most security systems. I suspect there would be ways of hiding this however... https://github.com/krisnova/boopkit...

eBPF – Running sandboxed programs in a privileged context such as OS kernel
This is a good write-up and I like the diagrams. What appears to still be missing in an "off switch". AFAIK there are still no kernel boot time commands to disable eBPF entirely. I have to recompile the kernel to disable it.
eBPF has the potential for file-less malware to run hidden from detection and I foresee the ability to tickle ring -3 (and -4?) CPU within CPU functions while bypassing local firewalls.
Here is some example code of what people already know how to do today and this list will grow as people discover more capabilities. [1][2][3][4][5] These do require some privileges to insert but will remain running and hidden until reboot.

Any alternatives to Life360/FindMy?
The only private alternatives are going to be self hosted and will require some technical skill. See owntracks for details.

Trying to make a pair of compasses that always point to each other
On your side, you need some way to be tracked. Easy solution is an app on your phone, I like OwnTracks as a privacy-respecting option.

I want more people to know about Obtainium.
It also allows me to keep Owntracks checked for updates while they sort out their current issue regarding being missing from F-Droid.

Privacy-focused Vehicle Tracking Tool?
Sounds like owntracks with a android headunit https://owntracks.org/
