The Snack sound extension adds commands for sound play/record and sound visualization, e.g. waveforms and spectrograms. It supports in- memory sound objects, file based audio, streaming audio, WAV, AU, AIFF, and MP3 file formats, synchronous and asynchronous playback. The visualization canvas item types update in real-time and can output postscript. New commands and file formats can be added using the Snack C-API.
wxPython is a Python extension module that wraps the wxWidgets cross-platform GUI library and provides an alternative to Tkinter and PythonWin. It attempts to mirror the class hierarchy of wxWidgets as closely as possible and is very versatile. It can be used to create standalone GUI applications or can be used in situations in which Python is embedded in a wxWidgets C++ application as an internal scripting or macro language. The currently supported GUIs are Win32, GTK/X-Windows, and Mac OS X.
gpsd is a daemon that listens to a GPS or Loran receiver and translates the positional data into a simplified format that can be more easily used by other programs, like chart plotters. The package comes with a sample client that plots the location of the currently visible GPS satellites (if available) and a speedometer. It can also use DGPS/ip.
fsh is a tool for establishing an ssh tunnel for remote execution of commands without requiring an ssh authentication on every connection. Once the tunnel is established, remote commands can be executed almost instantaneously. This makes systems such as remote cvs over ssh much faster. It includes fcp, an rcp variant that uses fsh.
Xfiles is an interactive utility for comparing and merging one file tree with another over a network. It supports freeform work on several machines (no need to keep track of what files are changed on which machine). Xfiles can also be used as a cross-validating disk<->disk backup strategy.
The Remote Microscope system consists of a server that manages the microscope and handles TCP connections, and Java-based client software that allows users to control the microscope. Currently the server software supports two different Leica microscopes, and two image acquisition devices.
