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.

improving download infra
Does something like casync (https://github.com/systemd/casync or https://github.com/folbricht/desync) serve any purpose or provide any advantage to propagating rpm changes over rsync?
-
Are there any true alternatives to Seafile? (Nextcloud is not an alternative in this context)
Software that comes to mind for syncing lots of small files: git (and other source versioning tools), casync (https://github.com/systemd/casync) and a go implementation (https://github.com/folbricht/desync). Not really an answer and I can't think of a way to shoehorn that into your workflow, but maybe it leads you down a useful road.

Mentioning the more portable desync is obligatory: https://github.com/folbricht/desync

Tool to clone file structure without the large files themselves?
You probably want casync.
-
LibSQL – a fork of SQLite that is both Open Source, and Open Contributions
(personally, I think more people need to be aware of casync for the update storage/distribution problem. It isn't perfect for every use case, but it's good enough that you're probably better off wrapping/forking it rather than reimplementing it badly from scratch)

Casync – A Content-Addressable Data Synchronization Tool
I was wondering how this gets any common chunks at all with the removed file boundaries. Turns out that chunks don't have a set size, just min/max/avg values, so unaligned streams may end up synchronizing. https://github.com/systemd/casync/blob/master/src/cachunker.... If I understood that correctly, that's pretty cool.
But looking at the code I'm having strong "nope" feelings. First, because of lines like "q += m, n -= m;". Second, because of int/enum/semantic abuse: `compression_type` may be _CA_COMPRESSION_TYPE_INVALID which I hope is 0, `>= 0` as a known compression type, or `-EAGAIN` as an error. (from https://github.com/systemd/casync/blob/99559cd1d8cea69b30022... ) I'd bet that just throwing afl at the decompressor will find issues :(
I do like the idea though.

Blobcache is a content addressed data store, designed to be a replicated data layer for applications.
Compare https://github.com/systemd/casync which handles splitting/diffing, but does not handle fancy replication.
