<h2>So, what is this pr0n thing anyway?</h2>
Also, it has dynamical rescaling (of good quality — proper,
sharp thumbnails, no crappy nearest-neighbor scaling) of both thumbnails
and images (most client-side scaling sucks quality-wise, unfortunately),

interface, cache awareness and in general good performance (being a set
of persistent, optimized Perl modules; I've seen it throw out over 300

would withstand a Slashdot attack ;-) ). Also, it has quite OK skinning
capabilities, so it's able to adapt into different designs quite
easily.</p>
<p>pr0n currently runs on two Intel E5-2650v3 (2x10 cores at 2.30GHz) with 64GB RAM and
SATA disks, with some SSDs in front for cache. (The server does a lot of other stuff besides running pr0n, of
- course.) pr0n itself is a custom-made system by myself, tightly coupled
- into <a href="http://www.apache.org/">Apache</a> 2.4,

<p>The Perl modules aren't really that big — we're talking about only
- approx. 3400 lines of code (of which ~25% is the WebDAV part; I should
- really make that a bit cleaner once). Most of the real work is done by

the software on which pr0n builds on.</p>
<h2>How much data is there in there, anyway?</h2>
- <p>At the time of writing, approximately 720GB of image data (that is, over
- 195000 different images), plus cache, plus metadata in the SQL database.

the images :-) If you really have a novel or cool feature, feel
free to contact me (see below).</p>
- <h2>Is the upload WebDAV server RFC-compliant?</h2>
-
- <p>Unfortunately, no. When and if somebody makes a sane framework for
- making WebDAV servers I can use, it probably will, but ATM it's just
- too much work for what I need it for. It would be a lot easier if
- I only had to support WebDAV level 1, but due to silly restrictions
- in Mac OS X' WebDAV client I have to support WebDAV level 2 as well,
- and, well, most of that is faked. ;-) In addition, there are multiple
- minor features in the system (like autorenaming files on name clashes)
- that just aren't easy to adapt to WebDAV. The WebDAV service is
- restricted, though, so I guess rather few people will get hurt just
- because I'm not fully compliant ;-)</p>
