Jaro Mail is an integrated suite of interoperable tools for GNU/Linux and Apple/OS X to manage email communication in a private way, without relying on online services (in fact, encouraging users to store email locally). It mainly features a system for mailinglist filtering, address-book integrated whitelisting, and long-term email storage and archiving with functions for fast search and usage statistics. It makes internal use of customized versions of popular Unix tools like Mutt, Fetchmail, Procmail, Mairix, and Msmtp.
STALLioN is a cross-platform C/C++ library for creating coherent CLI/Terminal programs on multiple platforms with one codebase. It aims to provide a consistent development API across multiple platforms so that separate code does not have to be created for each (often very different) terminal interface.
SysopView shows information in a visually attractive way, like computers in movies do. The idea is that it can show information relevant to system administrators non-comprehensible for non-technical personnel, while still looking attractive even if you don't know what is shown. The current version can show nagios status data, webcam streams (mjpeg, jpeg, and video4Linux), and VNC, has a built-in terminal emulator in which regular text applications can be run, can sniff the network (including remotely) and dissect streams and show pictures which are sniffed, can show external bitmaps (from, for example, mrtg and rrdtool), and can scroll text (currently showing output of rssfeeds).
Termdebug is a set of utilities for recording and replaying the input and output of terminal programs. Its main goal is to aid in developing and debugging terminal programs. Other programs such as termrec/termplay, nethack-recorder/player, and script/scriptreplay only record the output. However, when debugging an interactive terminal program, the input is often as important as the output.
