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.

ADG: Automatic Drawing Generation The ADG library (Automatic Drawing Generation) is a set of functions focused on automating the drawing of mechanical parts. It is not a CAD system but a library providing a non-interactive canvas where you can put common CAD entities such as paths, xatches and quotes, to create your technical drawings.

ADOdb ADOdb is a database abstraction library for PHP. The PHP version currently supports an amazing number of databases, thanks to the wonderful ADOdb community: MySQL, PostgreSQL, Interbase, Firebird, Informix, Oracle, MS SQL, Foxpro, Access, ADO, Sybase, FrontBase, DB2, SAP DB, SQLite, Netezza, LDAP, and generic ODBC, ODBTP. The Sybase, Informix, FrontBase and PostgreSQL, Netezza, LDAP, ODBTP drivers are community contributions. Some reasons why ADOdb is popular include:

• Designed for speed. It is probably the fastest free software database abstraction library available for PHP. See benchmarks.
• Provides extensive portability support such as date and type-handling and portable schema creation. See portable sql tips
• Support many enterprise features such as database backed sessions (with session expiry notification), SQL code generation, pivot tables, SELECT LIMIT emulation for all databases, performance monitoring.
• Easy to learn.
• Extensive QA, every release is unit-tested on Access, MySQL, PostgreSQL, MS SQL, Oracle 9.
• Mature, continuously developed since August 2000. Has a large community of users.
• Powerful Active Record support. See docs.
• Very reasonable licensing terms (BSD). This means that you can incorporate (and even compile) it into your software applications royalty-free without asking the author's permission, provided you include license.txt in your release.

ADOdb Lite A small, fast replacement for ADODB that uses 1/6th of the memory and upto 300% faster while being compatible with ADODB using a subset of the most often used ADODB commands.. Supports Frontbase, MaxDB, MiniSql, MSSQL, MySql, Postgres, SqLite and Sybase.

ADOdb for Python ADOdb is a database abstraction library. ADOdb was originally developed for PHP, and ported to Python. The Python version implements a subset of the PHP version. You might ask why Python needs a database abstraction library when Python provides the official DB API. Unfortunately the DB API does not encapsulate differences in the database implementations. For example, to select a limited number of rows, say 10 rows, you would have to use very different SQL for different databases:

• MS SQL select top 10 from table
• MySQL and PostgreSQL select * from table limit 10
• Oracle select * from (select * from table) where rownum <= 10
• These differences are handled by ADOdb (using SelectLimit), but not by the Python DB API. Other important database differences transparently handled by ADOdb include date-formating, associative arrays (records as dictionaries) and LOB-handling.

ALSA OSS The Advanced Linux Sound Architecture (ALSA) provides audio and MIDI functionality to the GNU/Linux operating system. ALSA has the following significant features:

• Efficient support for all types of audio interfaces, from consumer sound cards to professional multichannel audio interfaces.
• Fully modularized sound drivers.
• SMP and thread-safe design.
• User space library (alsa-lib) to simplify application programming and provide higher level functionality.
• Support for the older Open Sound System (OSS) API, providing binary compatibility for most OSS programs.

APE Tag Libraries C, Clojure, Erlang, Lua, Python, Ruby Libraries for reading/writing APEv2 tags.

ASCEND ASCEND IV is an object-oriented mathematical modeling environment, with similar functionality to programs such as GAMS, AMPL, Aspen, or Dymola. If can be used to solve difficult non-linear systems of equations and to plot dynamic behaviour of such systems. Although ASCEND has primarily been developed by Chemical Engineers, great care has been exercised to assure that it is domain independent. ASCEND can support modeling activities in fields from Architecture to (computational) Zoology.
