Bcvi is a tool that works with SSH to provide a secure "back channel" for sending commands back from the server to your workstation. For example, using bcvi and a shell alias, you can log into a server and type "vi filename". Instead of running vi in the terminal window, on the remote server, bcvi will send a message back to your workstation, where a listener process will invoke gvim (a GUI version of vim) and pass it an scp://... URL for the remote file. Bcvi has a plugin architicture that allows you to add support for any process you want to launch on your workstation by running a command on the server.
Oww (One-Wire Weather) is a client program for Dallas Semiconductor / AAG 1-wire weather station kits, providing a graphical (animated) display to monitor outside temperature, wind speed and direction, rainfall, and humidity. Extra temperature sensors may be added. A 1-wire "hub" may be used for improved reliability and range. Weather data may be logged to CSV files, parsed to command line programs, sent to the Henriksen Windows client, or uploaded to Web servers at Dallas, The Weather Underground, and HAMweather.
pv (Pipe Viewer) is a terminal-based tool for monitoring the progress of data through a pipeline. It can be inserted into any normal pipeline between two processes to give a visual indication of how quickly data is passing through, how long it has taken, how near to completion it is, and an estimate of how long it will be until completion.
