+# 「null:ポインタ」
+
+This is a no-bullshit file hosting and URL shortening service.
+Use with uWSGI.
+
+# Configuration
+
+To configure 0x0a, copy `instance/config.example.py` to
+`instance/config.py`, then edit it. Resonable defaults are set, but
+there\'s a couple options you\'ll need to change before running 0x0 for
+the first time.
+
+By default, the configuration is stored in the Flask instance directory.
+Normally, this is in [./instance]{.title-ref}, but it might be different
+for your system. For details, 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 has
+several downsides, one of them being that range requests will not work.
+This is a problem for example when streaming media files: It won't be
+possible to seek, and some ISOBMFF (MP4) files will not play at all.
+
+To make files expire, simply run `FLASK_APP=fhost flask prune` every now
+and then. You can use the provided crontab files for this.
+
+Make sure to edit them to match your system configuration, assuming
+you have read `crontab(5)` on a sane OS.
+
+Before running the service for the first time and every time you update
+it from this git repository, run `FLASK_APP=fhost flask db upgrade`.
+
+# Moderation UI
+
+![image](modui.webp){height="300px"}
+
+0x0a features a TUI program for file moderation. With it, you can view a
+list of uploaded files, as well as extended information on them. It
+allows you to take actions like removing files temporarily or
+permanently, as well as blocking IP addresses and associated files.
+
+If a sufficiently recent version of python-mpv with libmpv is present
+and your terminal supports it, you also get graphical file previews,
+including video playback. Upstream mpv currently supports sixels and the
+[kitty graphics protocol](https://sw.kovidgoyal.net/kitty/graphics-protocol/). For this
+to work, set the `MOD_PREVIEW_PROTO` option in `instance/config.py`.
+
+Requirements:
+
+* [Textual](https://textual.textualize.io/)
+
+Optional:
+
+* [python-mpv](https://github.com/jaseg/python-mpv) (graphical
+    previews)
+* [PyAV](https://github.com/PyAV-Org/PyAV) (information on multimedia
+    files)
+* [PyMuPDF](https://github.com/pymupdf/PyMuPDF) (previews and file
+    information for PDF, XPS, EPUB, MOBI and FB2)
+* [libarchive-c](https://github.com/Changaco/python-libarchive-c)
+    (archive content listing)
+
+** Note: [Mosh](https://mosh.org/) currently does not support sixels or kitty
+graphics.
+
+** Hint
+You may need to set the `COLORTERM` environment variable to `truecolor`.
+
+** Tip
+Using compression with SSH (`-C` option) can significantly reduce the
+bandwidth requirements for graphics.
+
+# NSFW Detection
+
+0x0a 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)
+-   [PyAV](https://github.com/PyAV-Org/PyAV)
+
+# Virus Scanning
+
+0x0 can scan its files with ClamAV's daemon. As this can take a long
+time for larger files, this does not happen immediately but instead
+every time you run the `vscan` command. It is recommended to configure a
+systemd timer or cronjob to do this periodically. Examples are included:
+
+    0x0a-vscan.crontab
+
+Remember to adjust your size limits in clamd.conf, including
+`StreamMaxLength`!
+
+This feature requires the [clamd
+module](https://pypi.org/project/clamd/).
+
+# Network Security Considerations
+
+Keep in mind that 0x0a can fetch files from URLs. This includes your
+local network! You should take precautions so that this feature cannot
+be abused. 0x0a does not (yet) have a way to filter remote URLs, but on
+Linux, you can use firewall rules and/or namespaces. This is less
+error-prone anyway.
+
+For instance, if you are using the excellent
+[FireHOL](https://firehol.org/), it's very easy to create a group on
+your system and use it as a condition in your firewall rules. You would
+then run the application server under that group.

-THE NULL POINTER
-================
-{% set fhost_url = url_for("fhost", _external=True).rstrip("/") %}
-HTTP POST files here:
-    curl -F'file=@yourfile.png' {{ fhost_url }}
-You can also POST remote URLs:
-    curl -F'url=http://example.com/image.jpg' {{ fhost_url }}
-If you don't want the resulting URL to be easy to guess:
-    curl -F'file=@yourfile.png' -Fsecret= {{ fhost_url }}
-    curl -F'url=http://example.com/image.jpg' -Fsecret= {{ fhost_url }}
-Or you can shorten URLs:
-    curl -F'shorten=http://example.com/some/long/url' {{ fhost_url }}
-
-It is possible to append your own file name to the URL:
-    {{ fhost_url }}/aaa.jpg/image.jpeg
-
-File URLs are valid for at least 30 days and up to a year (see below).
-Shortened URLs do not expire.
-
-Files can be set to expire sooner by adding an "expires" parameter (in hours)
-    curl -F'file=@yourfile.png' -Fexpires=24 {{ fhost_url }}
-OR by setting "expires" to a timestamp in epoch milliseconds
-    curl -F'file=@yourfile.png' -Fexpires=1681996320000 {{ fhost_url }}
-
-Expired files won't be removed immediately, but will be removed as part of
-the next purge.
-
-Whenever a file that does not already exist or has expired is uploaded,
-the HTTP response header includes an X-Token field. You can use this
-to perform management operations on the file.
-
-To delete the file immediately:
-    curl -Ftoken=token_here -Fdelete= {{ fhost_url }}/abc.txt
-To change the expiration date (see above):
-    curl -Ftoken=token_here -Fexpires=3 {{ fhost_url }}/abc.txt
-
