The GNU Gatekeeper is a free H.323 gatekeeper based on the OpenH323 project. You can use it to manage a Voice-over-IP network and let endpoints (e.g., Netmeeting) communicate through symbolic names. It also has an external interface for billing and other applications. It runs on a number of Unix versions (including Linux and Solaris) and Windows.
TinyCOBOL is an effort to bring a free COBOL compiler to Linux. It generates GNU assembler for the i386 Linux platform. A executable binary is then created using the GNU assembler and linker. The project is approaching the first beta release with many statements already implemented.
Netbiff is an advanced version of the traditional biff (a mail-checking program). Features include BSD mailbox and IMAP4 support, a backend plug-in system (for other protocols), arbitrary numbers of backends, pluggable interfaces (GTK and text-based), and arbitrary actions on biff.
The HP OfficeJet Linux driver provides printing, scanning, and photo-card access support for most Hewlett-Packard multi-function peripherals connected to a parallel port, USB port, or LAN via selected HP JetDirect print servers.

Full FTN mail support, including automatic routing for hub and host systems, is included. A Fidonet/Internet gateway is also built-in. The internal mail format is JAM (c) messagebase, and there is full tic file support, including extended tic files.
TAP provides packet reception and transmission for user-space programs. It can be viewed as a simple Ethernet device, which instead of receiving packets from a physical medium, receives them from a user-space program and instead of sending packets via physical media, writes them to the user-space program.
spim is a self-contained software simulator for running R2000/R3000 assembly language programs. It reads and can immediately execute files containing assembly language code. spim also provides a debugger and simple set of operating system services. spim provides both a simple, textual interface and a fancier, graphical interface. The package includes complete source code and documentation.
PLOTICUS is a command line utility for creating bar, line, pie, boxplot, scatterplot, sweep, heatmap, vector, timeline, Venn diagrams, and other types of charts and plots. ploticus is good for automated or just-in-time graph generation. It handles date, time, and categorical data nicely, and has some basic statistical capabilities. It can output to GIF, PNG, SVG, SWF, JPEG, PostScript, EPS, and X11. You can use convenient preset options or create complex scripts with rich and detailed color and style operations.
