ACM ACM is a LAN-oriented, multiplayer aerial combat simulation. Players engage in air to air combat against one another using heat seeking missiles and cannons. The program has support for 16, 24, and 32 bit graphics cards.

Abc2ps Abc2ps is a typesetting program for ABC, a code for typsetting music that uses standard ASCII characters. It reads a file containing abc code and outputs the music to another file in Postscript. The music can then displayed (i.e. using ghostview) or printed on a Postscript printer.

Abcm2ps abcm2ps is a package that converts music tunes from ABC format to PostScript. Based on abc2ps version 1.2.5, it was developed mainly to print baroque organ scores that have independant voices played on one or more keyboards, and a pedal-board. It introduces many extensions to the ABC language that make it suitable for classical music.

Abcpp 'abcpp' is a simple yet powerful preprocessor designed for, but not limited to, ABC music files. It provides conditional output, macros, symbol renaming, and file inclusion. It was written to overcome incompatibilities between ABC packages, and to facilitate writing portable, and more readable ABC files.

Abcsh 'abcsh', still in the planning stages, will be a shell for processing ABC music notation files. It could form the foundation of a larger system for music composition and orchestration using ABC music notation as a means of representing musical performance. The shell hopes to handle routine ABC transformation like part extraction, transposition, part merging etc. It will also be designed so that you can access the ABC notation file content from embedded scripting languages. It supports ABC music notation version 2.0. This project was a GNU package. It has since been decommissioned and is no longer developed.

Aldo Aldo is a Morse code tutor with three kinds of exercises: Classic exercise, the Koch method, and exercises read from files. In classic exercise, you must guess some random strings of characters that Aldo plays in Morse code. The package has 6 skills; speed can be selected in cpm or wpm.

Amber 'amber' aims to be an easy-to-use granular synthesis tool for GNU/Linux to assist composers and electronic musicians in creating interesting and complex sounds. More information on the theory and application of granular synthesis techniques can be found at http://shoko.calarts.edu/~eric/gs.html.

Atlc 'atlc' (Arbitrary Transmission Line Calculator) is a computer aided design (CAD) package for designing and analysing electrical transmission lines and directional couplers of totally arbitrary cross section, with an arbitrary number of different dielectrics. The analysis programs in 'atlc' lets users find the electrical properties of a transmission line or coupler whose physical dimensions are known. The design programs lets users physically realise a transmission line or coupler with certain given electrical properties. The package supports multiple CPUs, as some parts are CPU intensive. It is most likely to be useful to radio amateurs.

Avdbtools The avdbtools package (short for aviation database tools) is a collection of software designed to help create and maintain databases for aviation applications. This release of avdbtools is a single application that converts the National Airspace Data files distributed by the Aeronautical Information Systems Division of the Federal Aviation Administration into formats that other aviation related applications can use.

BEAST BSE BEAST is an abbreviation for Bedevilled Audio System. BSE an abbreviation for Bedevilled Sound Engine, it implements all the neccessary music processing logic required by BEAST in a seperate reusable library. The "Bedevilled" portion of the names has no religious background, but merely refers to the complexity involved implementing such a "BEAST" (pun intended ;).

BMI BMI is a tool to help dieters. It calculates your Body Mass Index (BMI) and gives you an indication of your fitness. It saves the results in a file, so you can through the program look at the file, and compare your results from day to day, which gives you an overview of your weight development over time.

BioImageXD BioImageXD - Free and open source software for analysis, processing and 3D rendering of multi dimensional microscopy images. It uses free software such as Python, wxPython, VTK, and is a free replacement for very expensive commercial 3D microscopy analysis and visualisation software BioImageXD is a collaborative open source free software project, designed and developed by microscopists, cell biologists and programmers from the Universities of Jyväskylä and Turku in Finland, and collaborators worldwide.

BlueLava BlueLava is a Web and WAP (CGI-based) x10 interface. Using commandline-based x10 tools as its backend, it allows you to control x10-compliant electronics and x10 modules from within a Web browser or a WAP/WML-enabled device. Uses of BlueLava include the remote control of lamps, appliances, and other electronics via the Internet.

Bpmdj 'bpmdj' (beats per minute DJ) is a set of free DJ'ing tools. The first is a very accurate BPM measurement tool. The second is a player which changes the tempo of music. It also allows for nudging, forward and backward movement by measures, and other nice things.

Bygfoot Football Manager Bygfoot Football Manager is a small and simple graphical football (a.k.a. soccer) manager game featuring many international leagues and cups. You manage a team from one such league: you form the team, buy and sell players, get promoted or relegated and of course try to be successful. You can customise Bygfoot by writing your own country definitions file or by creating your own team definitions files.

CWirc CWirc is a plugin for the X-Chat IRC client to transmit raw Morse code over the internet using IRC servers as reflectors. The transmitted Morse code can be received in near real-time by other X-Chat clients with the CWirc plugin. CWirc tries to emulate a standard amateur radio rig: it sends and receives Morse over virtual channels, and it can listen to multiple senders transmitting on the same channel. Morse code is keyed locally using a straight or iambic key connected to a serial port, or using the mouse buttons, and sound plays through the sound card, or through an external sounder.

Calibre It is free and cross-platform in design. calibre is meant to be a complete e-library solution and thus includes library management, format conversion, news feeds to ebook conversion, as well as e-book reader sync features and an integrated e-book viewer.

ChronoJump A complete system for measurement, management and statistics of sport short-time tests. Chronojump is used by trainers, teachers and students.

Cricket Scoreboard Cricket scoreboard for GNU/Linux displays almost real-time scores of a cricket match. It stays in the corner of your screen while you do other work. It picks up its data from www.rediff.com (http://www.rediff.com/cricket/score.htm). The scores are refreshed after 60 seconds; this can be forced by right-clicking on the window and selecting "Refresh!".

Cwdaemon 'cwdaemon' uses a PC parallel or serial port and a simple transistor switch to output Morse code to a transmitter from a text message sent to it via the UDP protocol. It uses the soundcard or PC speaker to generate a sidetone. Cwdaemon can also handle PTT, and band index output for automatic switching of antennas, filters etc. Pinout is compatible with the standard (CT, TRlog).
