NiL (which stands for NiL isn't Liero) is a multi-player game where the objective is to end the life of your opponents. NiL is set in a 2D world much like worms (from team17), but unlike worms it is not turn-based but realtime. NiL is mostly a clone of the old DOS game Liero, but unlike Liero it runs on Linux and is Free. NiL is not yet finished, but the game is already somewhat playable.
NinjaRMI is a free, ground-up reimplementation of Java Remote Method Invocation. It supports a number of features not found in Sun's RMI suite, including new communication semantics (one-way, unreliable, and multicast RMIs) and API enhancements (e.g., the ability to determine the hostname of the peer in an RMI connection). And, because all of the source code is provided, you're free to add new features as needed.

Nitfol is a portable interpreter for Z-machine code, the game format used by Infocom and more recently, Inform. Nitfol handles versions one through eight of the format, and attempts to comply with version 1.0 of the Z-machine specification. It includes typo-correction, automatic map generation, infinite undo, and a GDB-like source-level debugger.
nmh (new MH) is a powerful electronic mail handling system. It was originally based on version 6.8.3 of the MH message system developed by the RAND Corporation and the University of California. It is intended to be a (mostly) compatible drop-in replacement for MH. nmh consists of a collection of fairly simple single-purpose programs to send, receive, save, retrieve, and manipulate e-mail messages. Since nmh is a suite rather than a single monolithic program, you may freely intersperse nmh commands with other commands at your shell prompt, or write custom scripts which use these commands in flexible ways.
