The Null Pointer

This is a no-bullshit file hosting and URL shortening service that also runs 0x0.st. Use with uWSGI.

Configuration

To change settings, modify instance/config.py. For more information on instance configuration, see the Flask documentation.

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
