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.

Gcsfuse: A user-space file system for interacting with Google Cloud Storage
Hah nice! I developed https://github.com/ahmetb/azurefs back in 2012 when I was about to join to Azure. I'm glad Azure actually provides a supported and actively-maintained tool for this.

Prolly Trees
I don’t know who came first, but https://github.com/jacobgorm/mindcastle.io also uses the rsync/LBFS rolling hashes trick to split the tree data into chunks. I presented the idea at Usenix Vault 2019 https://m.youtube.com/watch?v=QgOkDiP0C4c&embeds_referring_e...

Gcsfuse: A user-space file system for interacting with Google Cloud Storage
It is not how you would want do it for a typical ML workload, where the samples have to get randomly permuted each epoch.
Instead, tar up the files in some random order, and put the tar file on a web server or bucket, then stream then in during the first epoch, while keeping track of their byte offsets in the tar file, which you cache locally, assuming ample local Flash storage. Then permute the list of offsets and use those when reading samples for the next epoch.
If you only have local HDD then you will need a more advanced data structure like the one provided by https://github.com/jacobgorm/mindcastle.io , which will allow you to write out permuted samples at close to disk sequential write bandwidth. See my talk at USENIX Vault 2019 for a full explanation, linked from https://vertigo.ai/mindcastle/
