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.

Is Posix Outdated?
The author needs to ask themselves: in this cloud technology stack, is there POSIX involved somewhere lower down, where I can't access it? The answer is, of course, "yes". The sort of cloud storage systems described all run on top of POSIX APIs. They provide convenience (cost efficiency is more debatable) compared to the POSIX alternative, but that's because they exist at an entirely different conceptual layer (hence the presence of POSIX anyway, just buried).
Your point about surfacing a POSIX that's actually there but hidden and thus visible to low-level Amazon employees building the S3 service which makes it invisible to S3 end customers is true but isn't the the point of the article. The author is saying there are motivations for a POSIX-like api visible also the end user.
So your explanation of stack looks like 2 layers: POSIX api <-- AWS S3 built on top of that
Author's essay is actually talking about 3 layers: POSIX <-- AWS S3 <-- POSIX
That's why the blog post has the following links to POSIX-on-top-of-S3-objects :

AWS Announces Open Source Mountpoint for Amazon S3
How is this different than these other solutions?

Introducing Mountpoint for Amazon S3 - A file client that translates local file system API calls to S3 object API calls like GET and LIST.
But now I ask.. why not s3fs? Is it the GPL licensing? Or even goofys that also have Apache2 licensing and seems to hit similar goals (non fully POSIX compliant)? Why build your own?

Migrating instance to AWS GovCloud
If your 20TB is in S3, use a staging box with goofys (https://github.com/kahing/goofys) to mount the commercial S3 bucket(s) into a folder, then use s3 sync to copy to your bucket(s) in GovCloud.

How do you manage large training datasets?
So, we just need to change the dataloader function a bit to make this work then. Did you try just mounting S3 using https://github.com/kahing/goofys. In this case, we need not even change the dataloader code. Not sure of the performance though.

Mount S3 Objects to Kubernetes Pods
We're using goofys as the mounting utility. It's a "high-performance, POSIX-ish Amazon S3 file system written in Go" based on FUSE (file system in user space) technology.

What you gonna add to your selfhost stack this year?
will probably experiment with https://github.com/kahing/goofys and https://litestream.io/ to make services more easily moved between the devices :) Also, will continue working on https://synpse.net/ to make the operations easier.

Like monitored_rsync, gofs use the fsnotify module to monitor file changes, and use inotify under linux.

Hello everyone, I created an Emacs-independent (doesn't require Emacs to be running) agenda notification app. I tested it under Doom Emacs and vanilla Emacs, and it worked fine, please try it and report any possible issues at GitHub. Thanks!
i don't use org-agenda but i was looking at you code and you may want to use fsnotify instead of a timer that may use more CPU than it should:

Running command when file is written to drive
I think you can try fsnotify altrough you will need Go do build the cmd part. Once built you can attach it folder and pipe output to other command.

When to run arbitrary/shell commands in go program.
Why not one of the native Go file watching libs (e.g. fsnotify/notify/etc)? In general you're much more likely to get better control over behaviour from native code than from shelling out.
