FireDucks: Pandas but Faster

> FireDucks is not a open source library at this moment. You can get it installed freely using pip and use under BSD-3 license and of course can look into the python part of the source code.

I don't understand what it means. It looks like a contradiction. Does it have a BSD-3 licence or not?

They provide BSD-3-licensed Python files but the interesting bit happens in the shared object library, which is only provided in binary form (but is also BSD-3-licensed it seems, so you can distribute it freely).

From the above link:

> While the wheel packages are available at https://pypi.org/project/fireducks/#files, and while they do contain Python files, most of the magic happens inside a (BSD-3-licensed) shared object library, for which source code is not provided.

BSD license gives you the permission to use and to redistribute. In this case you may use and redistribute the binaries.

Edit: To use, redistribute, and modify, and distribute modified versions.

Since it is under the BSD 3 licence, users would also be permitted to decompile and modify the shared object under the licence terms.

"Redistribution and use in source and binary forms, with or without modification, are permitted provided that the following conditions are met..."

https://opensource.org/license/bsd-3-clause

Such a crazy distortion of the meaning of the license.

Imagine being like "the project is GPL - just the compiled machine code".

This is pretty common for binary blobs for where the source code has been lost.

Nice insight!
