2do is a simple to-do list manager written in PHP and using a MySQL database backend. It supports unlimited numbers of projects, has templated HTML allowing for complete customisation, and can be publically viewable by all, or can be protected by passwords. Administration is done via simple Web-based forms.
ADODB is a set of advanced PHP database abstraction classes. It supports MySQL, PostgreSQL, Interbase/Firebird, Informix, Sybase SQL Anywhere, Oracle, MS SQL 7 and 2000, SAP DB, Sybase, DB2, FrontBase, Foxpro, Access, Netezza, LDAP, ODBTP, ADO, and generic ODBC. A metatype system is built in, making it possible to figure out that types such as CHAR, TEXT, and STRING are equivalent in different databases. It also features portable database creation, database-backed session support (with encryption), SQL performance monitoring, and database health checks.
The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
Accerciser lets you test all aspects of accessibility on the GNOME desktop. It uses AT-SPI to inspect and control widgets, allowing you to check whether an application is providing correct information to assistive technologies and automated test frameworks. It has a simple plugin framework that you can use to extend and customize the accessibility information displayed. It is written in Python and uses the pyLinAcc component from LSR to interact with AT-SPI using pyORBit. In essence, it is a next generation at-poke tool.
Albatross is a small and flexible toolkit for developing highly stateful Web applications. It provides browser-based sessions via automatically-generated hidden form fields, server side sessions via a session server or file-based session store, a powerful and extensible templating system which promotes separation of presentation and implementation for improved program maintainability, implicit handling for pagination of sequences and tree browsing, template macros to allow repeated HTML and special effects HTML to be defined in one location, and lookup tables to translate Python values to arbitrary template code. Applications can be deployed as either CGI programs or as mod_python module with minor changes to program mainline. Custom deployment can be achieved by developing your own Request class.
Amazon S3 Stream Wrapper is a PHP class that acts as a stream wrapper that can be used to get and send files to Amazon S3 (Simple Storage Service). It sends HTTP requests to access the Amazon S3 Web services API in order to store and retrieve files just by using fopen('s3://...') calls and using regular fwrite and fread functions to send and retrieve file contents from Amazon S3 servers. This stream wrapper class can also delete files, and create, list, and delete directories.
