activeMailLib is a PHP class that can validate email addresses and send MIME email messages using the PHP mail() function. It can generate text or HTML email messages with user-defined headers, body parts, and character encoding. File parts can also be attached to the messages. The class can also perform email address validation based on a regular expression. It can optionally check the addresses with the destination SMTP server using the PHP getmxrr() function on Unix-like systems.
ActiveShipping is a unified Ruby API (quite useful on Rails) for shipping information from multiple carriers. It calculates shipping, handling, finds the best price from multiple sources, etc. It is primarily focused on rate requests, but may be extended to cover other aspects of shipping as well. Currently, it includes UPS and USPS modules, and modules for Fedex and DHL are coming soon.
AdaCGI is an Ada95 interface to the "Common Gateway Interface" (CGI). AdaCGI makes it easier to create Ada95 programs that can be invoked by World Wide Web (WWW) HTTP servers using the standard CGI interface. Using it, you can create Web applications using Ada95 to perform queries or other processing by request from a WWW user.
AQuoSA is an open architecture for the provisioning of adaptive Quality of Service functionality into the Linux kernel. The project features a flexible, portable, and lightweight software architecture for supporting QoS-related services on top of a general-purpose operating system as Linux. The architecture is well founded on formal scheduling analysis and control theoretical results. At the core of the software is an adaptive Resource Reservation layer that is capable of dynamically adapting the CPU allocation for QoS-aware applications based on their run-time requirements.
Addresses is a GNUstep address book that consists of a full-featured address book manager application, a source-code compatible replacement for Apple's AddressBook.framework (for accessing and manipulating address data programmatically), a framework of view/editor classes that make it easy to use Addresses from your own programs, and a number of tools. It is easy to use by both users and programmers and can store almost all imaginable data, including multiple phone numbers, emails, and addresses, photos, AIM/Jabber/ICQ/Yahoo IM details, and notes. It supports drag-and-drop and integrates well with GNUMail.
The Advanced Foundation Classes (AFC) (formerly Amiga Foundation Classes) are a suite of C/C++ classes, originally born on Amiga computers, and ported to Linux. They provide a lot of basic classes, including a list manager, a Hash Table manager, a better string handler for C programs, a string parser, and more. One unique feature is documentation - AFC comes with a PDF manual of over 280 pages.
The adventure PHP framework (APF) is a utility to implement object oriented and generic PHP Web applications. It allows the developer to create programs in compliance with approved software design patterns, and the code base already has answers to many everyday problems. The framework cannot be described as an application that only has to be configured, but rather as a technical basis and design guide for the design of software. Further, it introduced many concepts and efficiency tools already well known in the Java community.
