Here are a few small things you might want to know about http://remaildr.com. Or maybe not, but then again, nobody forces you to read, stranger! “Hardware” Remaildr is hosted on an Amazon EC2 micro instance, benefiting of the free tier offer. Apart from the static IP that will probably end up costing me something, remaildr should be about free. – Edit: as of may, remaildr is now hosted on a VPS at OVH.

Photocard - a Java postcard generator

           java · linux

As a school project, we recently finished Photocard, a Java application for Linux that allows you to design postcards (‘we’ as in a couple of other students & me). Basically, Photocard listens to /media/ for an USB key, lets you chose a blueprint for your card (that might contain text and pictures), then drag and drop pictures into that blueprint, retouch them, and print your card (actually save it to /tmp/).

Tunneling iTunes through SSH

         OS X      itunes · linux · OS X

If you want to listen to your music library on the go, you can tunnel iTunes through SSH in a few easy steps. First of all, you have to enable sharing in iTunes: iTunes > Preferences > Sharing > Share my library on my local network. This will announce your library on your local network using multicast DNS, provided by Apple's implementation of zeroconf: Bonjour. The library can then be accessed on port 3689 of the computer mDNS announced.
