'Q' DVD-Author 'Q' DVD-Author is a GUI frontent for dvdauthor and related tools. The goal is to provide an easy-to-use, yet powerful and complete interface to generate DVD menus, slideshows, and videos to burn on a DVD under GNU/Linux.

123sqlengine 123sqlengine is a functional relational database engine still under development but featuring fully original database engine design

2532 Gigs 2532 Gigs is a PHP/SQL gig lister designed for bands and music sites. The Web-based Control Panel allows admins to add, edit, and delete shows and artists. Multiple users are supported, with two security levels (admin and staff).

2do 2do is a simple to-do list manager that supports unlimited numbers of projects, has templated HTML allowing for complete customisation, and can be either publically viewable or password-protected. It is administered through simple Web-based forms.

2wm 2wm is an extremely fast, small, and dynamic window manager for X. It is the little brother of dwm.

3D Pong A one-or-two player "pong" (ball and paddles) game for X-Window, drawn using vectors (lines). Different view modes are available, including split red/blue mode for using 3D glasses. Two players supported by connecting to multiple X-Window displays.

3DKit The GNU 3DKit is a platform independent rendering architecture based on OpenGL, written in ObjC. It is part of the GNUstep environment, which provides an object-oriented application development framework and tool set. As of July 25, 2002 the sources for the old 0.3.x versions can no longer be downloaded. Please contact the author if you would like the source code for the 0.3.x versions. This project was a GNU package. It has since been decommissioned and is no longer developed.

3DLDF 'GNU 3DLDF' is a 3D graphics package with MetaPost output. It is written in C++ using CWEB and includes documentation. The current stable release of GNU 3DLDF, 1.1.5.1, doesn't include an input routine, so user code must be written in C++, compiled, and linked with the rest of the program. However, the current development versions, collectively numbered 1.2.0.0 and available here, implement an interpreter for a Metafont-like language, so that GNU 3DLDF can be used interactively. Please see the GNU 3DLDF homepage, for more information.

3dFB '3dFB' is a 3D file manager and browser. 2D file managers work nicely, but with 3D, you can display much more information. The aim of this project is to make a viable, workable, 3D file manager that is not a hog on resources and can actually be usable.

4tH 4tH is a Forth compiler with a little difference. Instead of the standard Forth engine it features a conventional compiler. 4tH is a very small compiler that can create bytecode, C-embeddable bytecode, standalone executables, but also works fine as a scripting language. It supports about 95% of the ANS Forth CORE wordset and features conditional compilation, pipes, files, assertions, forward declarations, enumerations, structures, suspended execution, recursion, include files, etc. It comes with an RPN calculator, line editor, preprocessor, compiler, decompiler, C-source generator, a virtual machine, and a multitasking environment.

A Bingo Rails A/B testing. One minute to install. One line to set up a new A/B test. One line to track conversion.

A+ A+ is a powerful and efficient programming language. It has a rich set of functions and operators, a modern GUI with many widgets and automatic synchronization of widgets and variables, asynchronous execution of functions associated with variables and events, dynamic loading of user compiled subroutines, and many other features. Execution is by a rather efficient interpreter. It is mainly used in a computationally-intensive business environment, but many critical applications written in A+ have withstood the demands of real world developers over many years. It is written in an interpreted language, so applications tend to be portable.

A2K A2K (formerly known as Accutron 2000) is a small, simple, and unobtrusive IRC bot. It is meant to do only a few things, do them well, and generally be seen and not heard. It is written in Python, and thus should theoretically run anywhere you have Python and a working TCP/IP stack.

A2b a2b is an abstract train game where you guide trains to their destination without letting them collide with each other. Each game is played on a set of tracks on which trains run at regular intervals. You pick a train and accelerate, brake, or stop as necessary to safely guide it to its destination. Since trains are continously being launched, more than 1 train will want to use the same section of a track, potentially leading to a collision. You must resolve this by making a train wait while you rush another train. As a last resort, you can send a train back to its base.

A2png a2png converts plain text into PNG images. You can select which font to use and output dimensions. Text can either be read from files or standard input. This program uses either the Cairo Graphics library or the GD library for the rendering.

A2ps Program started as a text to PostScript converter, with pretty printing and all the expected features of this kind of program, but it can now handle other file types (PostScript, Texinfo, DVI, web-authoring, PDF, etc.) provided you have the necessary tools. While highly configurable, everything was designed so that even a novice can do complicated PostScript manipulations. For instance, the program can delegate the processing of some files to other filters (such as groff, texi2dvi, dvips, gzip,etc.) which allows a uniform treatment (n-up, page selection, duples, etc.) of heterogeneous files It also includes support for a wide range of programming languages, encodings (ISO Latins, Cyrillic, etc.), medias, and Native Language Support (NLS).

ABridge 'aBridge' lets you to play bridge online with other real people. It supports speech synthesis, so you can listen to the bids and chat conversation rather than simply gaze at the screen waiting for someone to play. aBridge also has some rudimentary bots, for when other players aren't online, but their AI is very basic.

ACDK ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but instead of using Basic/C# or Java as programming language, it bases C++ as core implementation language. ACDK implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml and more, as well as technologies like flexible Allocator/Garbage Collection, Threading and Unicode. With the extensions of ACDK C++ objects are available for reflection, serialization, aspect oriented class attributes and [D]ynamic [M]ethod [I]nvocation. This DMI act as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, VBScript) and standard component technologies (CORBA, COM+).

ACL2 ACL2 is a mathematical logic and a mechanical theorem prover to help you reason in the logic (which is a subset of applicative Common Lisp). The theorem prover is an ``industrial strength version of the Boyer-Moore theorem prover, Nqthm. Users can build models of all kinds of computing systems in ACL2, just as in Nqthm, even though the formal logic is Lisp. Once you've built an ACL2 model of a system, you can run it and use ACL2 to prove theorems about the model.

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.
