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.

Magika: AI powered fast and efficient file type identification
As someone that has worked in a space that has to deal with uploaded files for the last few years, and someone who maintains a WASM libmagic Node package ( https://github.com/moshen/wasmagic ) , I have to say I really love seeing new entries into the file type detection space.
Though I have to say when looking at the Node module, I don't understand why they released it.
Their docs say it's slow:
https://github.com/google/magika/blob/120205323e260dad4e5877...
It loads the model an runtime:
https://github.com/google/magika/blob/120205323e260dad4e5877...
They mark it as Experimental in the documentation, but it seems like it was just made for the web demo.
Also as others have mentioned. The model appears to only detect 116 file types:
https://github.com/google/magika/blob/120205323e260dad4e5877...
Where libmagic detects... a lot. Over 1600 last time I checked:
https://github.com/file/file/tree/4cbd5c8f0851201d203755b76c...
I guess I'm confused by this release. Sure it detected most of my list of sample files, but in a sample set of 4 zip files, it misidentified one.

Show HN: Magika: AI powered fast and efficient file type identification
We are very excited to announce the release of Magika our AI powered fast and efficient file type identification lib and tool - https://opensource.googleblog.com/2024/02/magika-ai-powered-fast-and-efficient-file-type-identification.html
Thanks to its optimized Keras model, large scale training dataset, and Onnx Magika massively outperform other file identification tools while be very fast even on CPU.
Magika python code and model is open sourced on Github: https://github.com/google/magika and we also provide an experimental TFJS based npm package https://www.npmjs.com/package/magika
With the team we hope you will find Magika useful for your own projects. Let us know what you think or if you have any question!

Magika: AI powered fast and efficient file type identification
Yes!
Sometimes a file has no extension. Other times the extension is a lie. Still other times, you may be dealing with an unnamed bytestring and wish to know what kind of content it is.
This last case happens quite a lot in Nosey Parker [1], a detector of secrets in textual data. There, it is possible to come across unnamed files in Git history, and it would be useful to the user to still indicate what type of file it seems to be.
I added file type detection based on libmagic to Nosey Parker a while back, but it's not compiled in by default because libmagic is slow and complicates the build process. Also, libmagic is implemented as a large C library whose primary job is parsing, which makes the security side of me jittery.
I will likely add enabled-by-default filetype detection to Nosey Parker using Magika's ONNX model.

Show HN: Nosey Parker, a fast and low-noise secrets detector for textual data
Yes and no.
On the one hand, Nosey Parker is effectively a special-purpose `grep` with a bunch of security-relevant patterns built-in, including one for PEM-encoded keys: <https://github.com/praetorian-inc/noseyparker/blob/main/data...>
On the other hand, to naively run the check you describe, you would need access to a copy of all of GitHub, which isn't feasible.
What you can do with Nosey Parker is use its GitHub enumeration features to specify your GitHub organization and a list of GitHub usernames you are interested in, and scan against just those. This will implicitly list all the relevant public repositories, clone them, and scan their entire history.
For your use case, another thing you could do is use the new GitHub code search (<https://cs.github.com>) to regex search for particular keys or tokens. That new search seems to cover lots of the public content available on GitHub.
Also, to put some color on this use case: in offensive security engagements (aka "red team" engagements) at Praetorian, we frequently find leaked credentials or tokens on GitHub or elsewhere, which allow us deeper access into the client's systems. It's a significant problem.
- Nosey Parker, a fast and low-noise secrets detector, now supports enumerating GitHub repositories and writing results in SARIF format
- Nosey Parker, a newer secrets detector, can scan 100GB of Linux kernel commit history in 2 minutes on a laptop, and now can write SARIF output
- Nosey Parker, a fast secrets detector, now enumerates GitHub repos, writes SARIF output, and has 90 default rules

Tools for scanning commits?
A tool just got open-sourced called Nosey Parker that scans commits and git history for secrets. You could look at Nosey Parker's source code to see how they scan commits and design your tool based on that.
