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.

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.

Access user Class Access_user Class is an easy to use system for protecting pages and register users. They main features are: User-login, user registration, user update, remember login information, page protection, forgotten password recovery, mail based account activation and multi language message reporting and since the latest versions: maintain extra user profile information, access levels, a limited (safe) admin panel, manual account activation and an improved password check. The class is powered by MySQL and PHP sessions. Inside the package are examples for all primary methods.

Action Mailer Action Mailer is a framework for designing email-service layers. These layers are used to consolidate code for sending out forgotten passwords, welcome wishes on signup, invoices for billing, and any other use case that requires a written notification to either a person or another system. Additionally, an Action Mailer class can be used to process incoming email, such as allowing a weblog to accept new posts from an email (which could even have been sent from a phone).

Action Query jQuery and ActiveRecord, sitting in a tree...

Active Resources Active Resource attempts to provide a coherent wrapper object-relational mapping for REST web services. It follows the same philosophy as Active Record, in that one of its prime aims is to reduce the amount of code needed to map to these resources.

Acts as Audited acts_as_audited is an Active Record plugin that logs all modifications to your models in an audits table. It uses a polymorphic association to store an audit record for any of the model objects that you wish to have audited. The audit log stores the model that the change was on, the “action†(create, update, destroy), a serialzied hash of the changes, and optionally the user that performed the action.

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.

Agile Toolkit Agile Toolkit is a powerful web development framework. Inspired by GUI Applications development, PHP "View" Objects in Agile Toolkit work seamlessly with HTML and jQuery. You can focus on developing Business logic and User Interface logic in pure high-level PHP code.

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.
