i have created debian backports to etch of current versions of mpd, rtorrent and mt-daapd and the dependencies needed to build / install them.

add

deb http://lefant.net/debian/ etch-backports main

to your /etc/apt/sources.list in case you are interested.

mt-daapd and rhythmbox are a great pair to store music on one computer and play on another, with little configuration on the server and none on the client, by the magic of zeroconf! highly recommended. should also work with itunes and other stuff from apple.

for some time now i have been using f-spot (website: http://f-spot.org/, which is a nice photo organization software for gnome. above all f-spot has great support for tagging, which in my opinion is a very important feature. you can also automatically create a static html thumbnail gallery for your website or export to flickr or gallery (the php thing many people seem to be using). however this way either you loose your tags (static html, gallery) or you handover your pictures and control over the url to flickr (which limits you to 200 pictures in their free plan anyway).

phpfspot (website: http://oss.netshadow.at/oss/phpfspot/Project, freshmeat: http://freshmeat.net/projects/phpfspot/) to the rescue!

after some whining on my part at work my colleague at work andreas unterkircher started looking for a better webfrontend solution (foremost including good support for the tags) himself and, finding none, started coding. for reference there is pennave with a similar goal (website: http://pennave.sourceforge.net/), however speed was really lacking and development very slow).

i am now happily running phpfspot myself (link: http://gallery.lefant.net/). i also use the thumbnail export feature to create thumbnail galleries for use in the debienna wiki (link: http://debienna.at/). the thumbnails on the starting page are created dynamically for each page visit (try reloading, see http://debienna.at/?action=raw for the page source and the RandomQuote hack) which uses the FotoFortunes wiki page as its source (warning, huge page). using phpfspots export feature i can now create the content of the FotoFortunes page automatically after selecting all pictures with the debienna tag.

the same works with literal html for blog entries like this one. find a thumbnail gallery of all my images tagged with "screens" below:

i am happy, thanks unki!

welcome to the home of LeShaper script...

since wondershaper only almost did what i wanted and sometimes pings were slow when they shouldn't have been and i couldn't figure out why. i thus followed the "keep it simple stupid" principle, use tbf and prio and created my own version of a "slow down the uplink so the queue is local, always prioritise ssh/dns/fill-in-your-favourite-kind-of-nework-traffic, but give all idle bandwith to whatever can make use of it"-bandwith shaper.

i hope it may also save someone else some trouble. darcs based version control is easy, so why not use it. questions and comments welcome.
