Kangee is a personal on-demand fileserver that makes it possible to send files to your friends. Dragging a file into the Kangee window will generate a link, which can be sent to your friend, who may open it in a Web browser and download the file. It also supports an "Add Upload" feature, which generates a link that lets your friends send files to you. It uses UPnP, STUN, and a connection test Web service to set up incoming connections, and can generate QR codes from the links to uploads and downloads.
ctm.pl is a Perl script which generates Apache type maps for use with mod_negotiation. Useful if you have a lot of images available in different formats you need type maps for, especially if you don't want to use MultiViews to decide which of them will be sent back to the requesting browser.
