Sure thing :)

Here's[0] a .tgz file with 3 files in it that are misidentified by magika but correctly identified by the `file` utility: asp.html, vba.html, unknown.woff

These are files that were in one of my crawl datasets.

Thank you - we are adding them to our test suit for the next version.

Super, thank you! I look forward to it :)

I've worked on similar problems recently so I'm well aware of how difficult this is. An example I've given people is in automatically detecting base64-encoded data. It seems easy at first, but any four, eight, or twelve (etc) letter word is technically valid base64, so you need to decide if and how those things should be excluded.

Do you have permission to redistribute these files?

LOL nice b8 m8. For the rest of you who are curious, the files look like this:

    <HTML><HEAD>
    <TITLE>Access Denied</TITLE>
    </HEAD><BODY>
    <H1>Access Denied</H1>
     
    You don't have permission to access "http&#58;&#47;&#47;placement&#46;api&#46;test4&#46;example&#46;com&#47;" on this server.<P>
    Reference&#32;&#35;18&#46;9cb0f748&#46;1695037739&#46;283e2e00
    </BODY>
    </HTML>
Legend. "Do you have permission" hahaha.

You are asking what if this guy has "web crawl data" that google does not have?

And what if he says no, he does not have permission.

No, I'm asking if he has permission to redistribute these files.

Are you attempting to assert that use of these files solely for the purpose of improving a software system meant to classify file types does not fall under fair use?

I'm asking a question.

Here's another one for you: Do you believe that all pictures you have ever taken, all emails you have ever written, all code you have ever written could be posted here on this forum to improve someone else's software system?

If so, could you go ahead and post that zip? I'd like to ingest it in my model.

Your question seems orthogonal to the situation. The three files posted seem to be the minimum amount of information required to reproduce the bug. Fair use encompasses a LOT of uses of otherwise copyrighted work, and this seems clearly to be one.

It's three files that were scraped from (and so publicly available on) the web. That's not at all similar to your strawful analogy.
