AQtime is an integrated performance and memory/resource optimization toolset aimed at applications running on the Linux platform. It can be used to discover application bottlenecks, memory leaks, resource-hogging code, or untested algorithms in any software projects. It then informs you which module, class, routine or line of code is causing the problem, and lets you quickly fix it. It can profile any executable that has the Executable and Linking Format (ELF) and the stabs format of the debug information.
ARSCIF is a powerful framework that makes it trivial to use asynchronous remote-script callback invocation (AJAX) techniques. It helps the developer by working out problems such as data and character encoding, concurrency control, browser implementations, and so on, allowing the creation of pages with sophisticated, dynamic features.
AS2Secure is a PHP library that allows you to send and receive AS2 (Applicability Statement 2) messages from partners. The project is split into two parts: a client to send one or more documents to a partner and a server to receive one or more documents from a partner. Its main features are asyncronous and syncronous MDN, partner setup, digital signatures, message encryption, secure transport (using OpenSSL), support for SSL client authentication, and multiple attachments (AS2 1.2).
ASAPlate separates PHP source code from templates. The library is based on FastTemplate, but the project has a different philosophy. It is easy to learn and use. There's no need to especify in the source code which templates will be found in the template files. Template files can be edited with any WYSIWYG editor, can be dynamic, and are recursively parsed.
