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.

BTFS (BitTorrent Filesystem)
https://github.com/uber/kraken?tab=readme-ov-file#comparison...
"Kraken was initially built with a BitTorrent driver, however, we ended up implementing our P2P driver based on BitTorrent protocol to allow for tighter integration with storage solutions and more control over performance optimizations.
Kraken's problem space is slightly different than what BitTorrent was designed for. Kraken's goal is to reduce global max download time and communication overhead in a stable environment, while BitTorrent was designed for an unpredictable and adversarial environment, so it needs to preserve more copies of scarce data and defend against malicious or bad behaving peers.
Despite the differences, we re-examine Kraken's protocol from time to time, and if it's feasible, we hope to make it compatible with BitTorrent again."

DockerHub replacement stratagy and options
For within your boundary of control, whether that be r/selfhosting, r/homelab, or enterprise a small registry or something like uber's kraken registry makes more sense.

MinIO passes 1B cumulative Docker Pulls
Uber Engineering open-sourced Kraken [1], their peer-to-peer docker registry. I remember it originally using the BitTorrent protocol but in their readme they now say it is "based on BitTorrent" due to different tradeoffs they needed to make.
As far as I know there aren't any projects doing peer-to-peer distribution of container images to servers, probably because it's useful to be able to use a stock docker daemon on your server. The Kraken page references Dragonfly [2] but I haven't grokked it yet, it might be that.
It's also possible that in practice you'd want your CI nodes optimized for compute because they're doing a lot of work, your registry hosts for bandwidth, and your servers again for compute, and having one daemon to rule them all seems elegant but is actually overgeneralized, and specialization is better.

Ask HN: Have You Left Kubernetes?
If you're pulling big images you could try kube-fledged (it's the simplest option, a CRD that works like a pre-puller for your images), or if you have a big cluster you can try a p2p distributor, like kraken or dragonfly2.
Also there's that project called Nydus that allows starting up big containers way faster. IIRC, starts the container before pulling the whole image, and begins to pull data as needed from the registry.

BiglyBT is a feature filled, open source, ad-free, BitTorrent client
Some systems are more appropriate than just those options, but it requires player cooperation.
For instance on Android, NOVA Video Player supports torrent streaming. Or btplay from https://github.com/johang/btfs .
The way they work is better for the network, because it asks only for the N next MB from current position to be available ASAP, but the rest can be downloaded randomly to help the network like a standard client would do.
