The Null Pointer

================



This is a no-bullshit file hosting and URL shortening service that also runs

`0x0.st <https://0x0.st>`_. Use with uWSGI.



Configuration

-------------



To change settings, modify ``instance/config.py``. For more information on

instance configuration, see `the Flask documentation <https://flask.palletsprojects.com/en/2.0.x/config/#instance-folders>`_.



To customize the home and error pages, simply create a ``templates`` directory

in your instance directory and copy any templates you want to modify there.



If you are running nginx, you should use the ``X-Accel-Redirect`` header.

To make it work, include this in your nginx config’s ``server`` block::



    location /up {

        internal;

    }



where ``/up`` is whatever you’ve configured as ``FHOST_STORAGE_PATH``.



For all other servers, set ``FHOST_USE_X_ACCEL_REDIRECT`` to ``False`` and

``USE_X_SENDFILE`` to ``True``, assuming your server supports this.

Otherwise, Flask will serve the file with chunked encoding, which sucks and

should be avoided at all costs.



To make files expire, simply create a cronjob that runs ``cleanup.py`` every

now and then.



Before running the service for the first time, run ``FLASK_APP=fhost flask db upgrade``.





NSFW Detection

--------------



0x0 supports classification of NSFW content via Yahoo’s open_nsfw Caffe

neural network model. This works for images and video files and requires

the following:



* Caffe Python module (built for Python 3)

* ``ffmpegthumbnailer`` executable in ``$PATH``
