- <h1>pr0n FAQ</h1>
- <p>Last updated July 23rd, 2006</p>
-
- <h2>So, what is this pr0n thing anyway?</h2>
-
- <p>pr0n is my very own gallery system. It is used on a few different
- host names, most notably at <a href="http://pr0n.sesse.net/">pr0n.sesse.net</a>
- to show images I and others have taken at events I care about (some
- more than others, of course).</p>
-
- <h2>Why the name? Is this some kind of fetish site?</h2>
-
- <p>The name "pr0n" (scriptkiddie-speak for "porn", of course) was just seen
- as a very good fit for an image gallery. :-) There is no (and will not
- be any) adult content on this site.</p>
-
- <h2>Can I upload my own images here?</h2>
-
- <p>Yes, you can, as long as they're related to one of the events already
- here. Contact me (see the bottom of the page) for more information.</p>
-
- <h2>Can I download all the pictures for viewing?</h2>
-
- <p>Sorry, no. First of all, please don't use any "web mirroring" program to
- download all the images -- of course, I can't stop you, but you're
- putting a lot of unneccessary load on the system. There are two main
- reasons for not downloading all the pictures: First, there is a
- question of copyright; not all images here are taken by me, and I've
- been given permission to display them here, not to pass them on. Second,
- keep in mind that some of the events contain several gigabytes of images --
- do you really need all that? I'd advise you to crank up the thumbnail
- size to the maximum possible size instead; it's quite comfortable to
- browse images on without having to click back and forth all the time.</p>
-
- <h2>I just changed thumbnail resolution, why is everything so slow?</h2>
-
- <p>Probably the requested size was never generated before, so the server
- has to scale all the images. As the scaling method used is geared
- towards getting good-quality, sharp thumbnails, not speed, this can
- take a while. It's all getting cached on disk for later re-use, though,
- so the next time somebody views the same images in that resolution,
- it will be snappy as usual.</p>
-
- <h2>Why didn't you just throw up Gallery?</h2>
-
- <p>Because it didn't fit my needs, and the same goes for all other systems
- I've seen. I wanted something no-nonsense that would work for <em>my</em>
- purposes -- I don't want to click around endlessly just to watch some
- pictures. Others are of course free to do as they wish, I can't impose
- my will on anybody :-)</p>
-
- <h2>What are the primary features of pr0n?</h2>
-
- <p>Mostly that it's no-nonsense and just works, without being in your way.
- 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),
- an easy-to-use <a href="http://www.webdav.org/">WebDAV</a>-based upload
- interface and in general good performance (being a set of persistent,
- optimized Perl modules; I've seen it throw out over 300 hits a second,
- but I won't guarantee it would withstand a Slashdot attack ;-) ). Also,
- it has quite OK skinning capabilities, so it's able to adapt into
- different designs quite easily.</p>
-
- <h2>What hardware/software does it run on?</h2>
-
- <p>pr0n currently runs on an Athlon 64 X2 3800+ with 2GB RAM and ordinary
- SATA disks. (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> 2.0, <a
- href="http://perl.apache.org/">mod_perl</a> 2.0 and <a
- href="http://www.imagemagick.org/">ImageMagick</a> 6.x (as well as various
- other Perl modules), using <a
- href="http://www.postgresql.org/">PostgreSQL</a> 8.1 as the back-end
- database for metadata et al. The base operating system is <a
- href="http://www.debian.org/">Debian</a> etch (ie. “testing”).</p>
-
- <p>The Perl modules aren't really that big -- we're talking about only
- approx. 1500 lines of code (of which ~30% 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 45GB of image data (that is, over
- 36000 different images), plus cache, plus metadata in the SQL database.
- (These numbers are growing rather rapidly, so they could be outdated at
- any given time.)</p>
-
- <h2>Can I get the source?</h2>
-
- <p>Probably, but are you sure you can get it to work? It's
- non-trivial to set up, as it depends on lots of odd modules and a lot of
- custom configuring; this is not a pre-made, user friendly package for your
- favourite Linux distribution. There is a bzr repository at
- <a href="http://bzr.sesse.net/pr0n/">http://bzr.sesse.net/pr0n/</a>, but
- going to hold your hand configuring it. :-) (Hint: If you do not know what
- bzr is, and cannot find out on your own, pr0n is not for you.)</p>
-
- <h2>Will you implement feature X?</h2>
-
- <p>Probably not; I have a lot of things to do besides programming new
- features. Also, I'm not really sure if I want tons of stupid people
- writing stupid comments under my images, or icky HTML pages with
- "previous" and "next" buttons instead of just getting directly to
- 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>

- <h2>How do I get in touch with you?</h2>
-
- <p>Try <a href="mailto:sgunderson@bigfoot.com">e-mail</a>, or reach me
- on IRC as Sesse on EFnet, IRCnet, Freenode or OFTC.</p>
