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.

We reduced conda’s index fetch bandwidth by 99%
For arbitrary state changes however, it's better to use something like casync. Note that there are a lot of tunables, implicit and explicit; for package indexing I would particularly think about "how is the index sorted" and "what is the desired chunk size".

Intro to Content Defined Chunking
If you just want something practical to play with, see casync. Even if it doesn't fit your workflow, or if you think you can do better, chances are you're best off building on top of it or adding patches to it, not starting from scratch.

Tool to clone file structure without the large files themselves?
You probably want casync.
-
A Nibble of Content-Defined Chunking - How de-duplicated, incremental file transfer works
Obligatory link to casync, which implements this better than most alternatives.

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)

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.

Rclone syncs your files to cloud storage
Says that Apple doesn't provide a multi platform API. It doesn't provide any official supported way to access iCloud from Windows, Linux.
There's a ticket covering everything you might ever want to know:

Ask HN: Best modern file transfer/synchronization protocol?
seconding rsync and syncthing.
the server could expose an smb or nfs share, the client could mount it, and then sync to that mount.
rsync over ssh also works, if you do not want to run smb/nfs.
this is also a cool tool https://rclone.org/

Ask HN: How do you do personal backups in 2023? (Google and Dropbox issues)
rclone [1] to dropbox. works since years without problems

Which synchronization tool are you using together with the pCloud Crypto Folder?
rclone provides a special pCloud config option, which makes the setup straight forward. rclone can encrypt the data it uploads with its own encryption but not with the pCloud encryption. Therefore it can only upload data to the unencrypted pCloud folders, not to the Crypto Folder.

All I want for Christmas is
The arkclone project impliments rclone in ArkOS to achieve cloud saves. Not yet built in to ArkOS yet, and not a lot of recent traction on the pull request to get it added, but it can be installed manually.
