The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
Audiality is a highly scalable and portable audio engine and synthesizer. MIDI files are used in combination with scripting and modular synthesis, to minimize file sizes and maximize flexibility. Audiality can be used as a music and sound effects player in multimedia productions, or as a realtime MIDI synthesizer.
BZFlag is a 3D, multiplayer, tank battle zone, capture the flag game that pits players against each other in a networked environment. It runs on Windows 95/98/NT/2000, Linux, MacOS 10.x, Irix, Solaris, and others. An OpenGL accelerator is highly recommended, but it is playable with 3D in software.
The Extended Module Player is a command-line mod player for Unix-like systems that plays over 90 mainstream and obscure module formats from Amiga, Atari, Acorn, Apple IIgs, C64, and PC, including Protracker (MOD), Scream Tracker 3 (S3M), Fast Tracker II (XM), and Impulse Tracker (IT) files.
The FAAC project includes the AAC encoder FAAC and decoder FAAD2. It supports several MPEG-4 object types (LC, Main, LTP, HE AAC, PS) and file formats (ADTS AAC, raw AAC, MP4), multichannel and gapless en/decoding as well as MP4 metadata tags. The codecs are compatible with standard-compliant audio applications using one or more of these profiles.
FIGlet is a program for making large letters out of ordinary text. It prints its input using large characters made up of ordinary screen characters. FIGlet output is generally reminiscent of the sort of "signatures" many people like to put at the end of email and UseNet messages. It is also reminiscent of the output of some banner programs, although it is oriented normally, not sideways.
Free Java is a development environment designed to help beginners write Java programs. Its editor includes syntax highlighting and an undo/redo function. It features a structure panel and a file browser. Compiling and running a program can be done with the push of a single button, and compiler errors are shown clearly. There is also a virtual console to show a program's console output. Free Java is based on J2SDK 1.3.
FrobTADS is a complete rewrite of the Unix console-version of TADS ("Text Adventure Development System"). It uses curses (or ncurses) and provides an interpreter to play games developed with TADS as well as the TADS 2 and 3 development tools. It adds support for a number of relatively recent user interface features including full support for text and background colors, TADS 3 banner windows, and timed input. It's also much more portable and more easily maintainable, as it's built to modern Unix standards.
GNU libsigsegv is a library for handling page faults. A page fault occurs when a program tries to access a region of memory that is currently not available. Catching and handling a page fault is a useful technique for implementing garbage collectors, stack overflow handlers, persistent databases, and distributed shared memory.
