Acts as fu: When you need a dash of ActiveRecord and nothing more. Now you have no excuse for not test-driving your ActiveRecord extending plugins.

Ada Components: A component library for the Ada language. The four main categories are data structures, math, Ada programming tools, and OS interface.

Ada Motif binding library: SERC's Ada/Motif is a complete binding to X Windows and OSF/Motif for the Ada programming language it was based in part upon the SAIC/Unisys (STARS) public-domain bindings it incorporates many of the bug fixes and additional capabilities beyond the public-domain releases in Ada/Motif. Most noteworthy are the capabilities included in Ada/Motif for Ada tasking, callback registration, memory leak detection/prevention and capabilities for developing customized widgets. Paramax/STARS considers Ada/Motif to be the commercial version of their STARS bindings, according to SERC.

AdaDoc: AdaDoc is a tool for Ada 95 developers. It creates an HTML file from a package specification for documentation purposes.

AdaSockets: 'AdaSockets' is a library that lets you use sockets in Ada 95. It supports unicast and multicast sockets, and uses object oriented structures to ease sockets manipulation.

AdaUnits: 'AdaUnits' provides an implementation of dimensioned values for Ada. Unit checks are made at run-time, if not optimized out by the compiler. The package supports SI and irregular measurement units and shifted units (like degrees Celsius). Conversions from and back to strings are provided for all various irregular units.

AdacURL: AdacURL is an Ada95 binding to the popular curl library for fetching files over various protocols such as HTTP, FTP, or TELNET.

Algol 68 Genie: Algol68G (Algol 68 Genie) is an Algol 68 implementation. Its front-end parses an entire Algol 68 source program. If parsing is successful, the syntax tree (that serves as an intermediate program representation) is interpreted by Algol68G's back-end. The interpreter performs many runtime checks.

Amnesia: Hopefully with Amnesia you'll know exactly whats happening with memory when it comes to memcached. Its always nice to have some statistics to see how everything is performing within your stack. Memcached seems to be a mystery box that people don't really pay alot of attention to. Amnesia tells you how your application is performing, when it misses, when it is running sweet, when you're about to run out of memcached and (perhaps) fall down in a screaming heap.

Anemone: Anemone is a Ruby library that makes it quick and painless to write programs that spider a website. It provides a simple DSL for performing actions on every page of a site, skipping certain URLs, and calculating the shortest path to a given page on a site. The multi-threaded design makes Anemone fast. The API makes it simple. And the expressiveness of Ruby makes it powerful.

Apl: GNU APL is an interpreter for APL as described in ISO standard 13751, aka. "Programming Language APL, Extended". This free version of the programming language APL has already implemented the latest and greatest features (nested arrays and related functions, complex numbers, shared variables) and is intended to be a full implementation of the standard. GNU APL has builtin support for Emacs (gnu-apl-mode). GNU APL has a predefined keyboard layout in order to produce APL characters when the "Alt" key is held down. The layout can be customized by the program xmodmap and a new keyboard mapping table like "apl.xmodmap" provided in source: xmodmap apl.xmodmap Text files beginning with #!apl run the interpreter as a shell with the subsequent lines as input.

Apydia: Apydia is an API reference documentation generator for Python. It's designed as an instantly serviceable replacement for Pudge's API-documentation generator. It won't generate complete websites from reST etc. like Pudge does, though - Apydia is only about the API.

AsmEdit: 'AsmEdit' is an editor and IDE written in assembler. It includes source highlighting and support for external helper programs for compiling and debugging. It contains word processing features such as paragraphing and spelling in a binary of less than 20,000 bytes.

AsmRef: 'AsmRef' includes a menu system and search function to display data on the Linux kernel and most topics associated with x86 assembler development on GNU/Linux systems.

Asset Trip: Asset Trip bundles JavaScript and CSS files at deploy time. The assets are then served from a Git-esque object store in the applicationÃ¢â¬â¢s public directory.

Association Freezer: Freeze an Active Record belongs_to association to ignore any future changes.

Atrack is a ntrack / Bittorrent tracker designed from the ground up to run on Google's App Engine grid. Its main goals are:

As small codebase as possible.
As fast as possible.
As low bandwidth usage as possible.
As low memory usage as possible.
For this it relies heavily (and almost completely) on memcached, no data is stored anywhere, and it lets memcached do most of the lifecycle management. Atrack also aims to respect your privacy: other than what is needed for the most basic tracking (hashes/keys and ip/ports) atrack gathers no information whatsoever. Beyond that no aggregate statistics are kept of anything (at least once the testing/debugging phase is over), and nothing is stored permanently anywhere, not even hashes and ip/ports, they are kept in memory until they are expired by memcached and never written to disk or any other kind of permanent storage.

BFFFT: Using a simple array as input, a 2-dimensional Fast Fourier Transform consists of two one-dimensional FFTs performed (for instance) on each line first, and on each column next. An important limitation in FFT computer applications dealing with large arrays is the fact that the algorithm is not well suited to parallelization, due to the huge amount of data that has to be transfered between computers. Since the transfers are proportional to the number of operations, network time soon becomes prominent when the number of processors is high. This program uses vectorization as an alternative to parallelization methods.
