httpMonitor is a Python program which lets you monitor the HTTP traffic between a browser and a Web server. You configure your browser to use httpMonitor as its proxy to ensure that all HTTP traffic between browser and server goes via httpMonitor. In a XML-configuration file you can specify a Python-function as processor for the HTTP-messages you are interested in (requests or responses, which match certain criteria). You may have as many processors as you want, without modifying the actual program. The only thing you need to do is configure the httpMonitor and write your processors.
Plotter is a GTK+ mathematical graph plotting application. It is written entirely in Python using the PyGtk bindings. Features of Plotter include plotting of cartesian, parametric, and polar equations. An unlimited number of plots can be displayed in individual colours. Plotter supports graph zooming and panning, and loading and saving of sets of graphs. New functions can easily be added from within the program.
juked is a daemon that turns a server into a music jukebox. Clients communicate with the server via TCP/IP using an XML protocol. It features playlist support, user authentication (optionally with PAM), and random track selection. Audio decoding is done using XMMS plugins, so both Ogg and MP3 are supported. Track (song) information can be stored internally or in a MySQL database.
