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.

Who invented file extensions in file names?
https://www.darwinsys.com/file/
This is the authors website. Apparently yeah its not part of GNU utils, I had no idea, I knew it came with most Linux systems so I looked for the Debian package and found the site linked above.

TIL: Github seems to recognize ebuilds as a format. Is this a new github feature? Or has this been here since forever?

How do I make a transparent background on .ps or .eps file imported to groff
in installations of Linux, file is a command to retrieve some basic information about a file type. Because contrasting to the organization of Windows, the file extension in Linux can be less important for the file's use (even irrelevant), than the actual content.

Why does Linux file command shows java file as C++ source?
In this case, it's hitting this set of rules. I would guess it hits both class and public.

How many “encodings” are there?
But I don't think this is what you meant. I think your question is something more like: how many file formats are there? The Unix file command recognizes several thousand, and Wikipedia has a list. Of course these are only the most common, and it's hard to delineate what counts as a unique file format. (Is YAML one file format or millions?)

Can I change the mime type of OGG Vorbis and Opus files without re-encoding them?
The magic number for all ogg files is the same (OggS) and files magic file looks like it decides the mime type based on the codecs used in the file. However, it looks like application/ogg is used only if the file contains Kate (Karaoke and Text) content.

Is this possible with Python?
other than Pandas, you can also use tablib. I personally find tablib to be slightly easier but it doesn't have as many features. But for what you need, tablib might be best

Fun with File Formats
There are two problems leading to the decision of only accepting public domain info: licensing and provenance.
"Licensing" is hard. The "Open Specifications Promise" [1], which covers a bunch of Microsoft-designed file formats, is merely a covenant not to sue.
"Provenance" is tricky. For example, much of the knowledge of the Apple iWork formats were derived by reverse-engineering the source programs and extracting protobuf definitions. Many open source projects have freely copied from each other, making detailed analysis tricky [2].
