Admin4 is a tool for server maintenance via several plugin modules, running on Windows, Mac OS X, Linux, and many more platforms. Currently, plugins for BIND DNS, LDAP, and PostgreSQL are included. It is designed as a framework, using Python for fast development of plugins and custom modifications. The DNS plugin should be able to query (axfr) any type of server, and performs updates via DDNS, which ensures that it won't interfere with other DDNS clients (DHCP, SAMBA4). For BIND 9.7 and up, statistics are supported as well and used to retrieve the server's zones automatically. The LDAP plugin features browsing and generic editing of all types of LDAP entries with schema support. In addition, high-level editing of objects like users, groups and samba domains is supported. Custom objectClasses and attributes can easily be added. The goal of the plugin was to replace the Windows-only ldapadmin tool with a portable solution.
PHP Debug is single API for tracing PHP applications. With a single file of only 200 lines, you can add, with minimal impact, diagnostics to be displayed upon program termination. Each diagnostic contains file, function, and caller function information. You just need to include the debug.php file and add debug() calls throughout your code in the same way as var_dump(). The diagnostic messages are stored and displayed in a list. Diagnostics can be disabled and controlled. It's small and simple yet very versatile.
Pyrseas provides a framework and utilities to upgrade and maintain a relational database. It currently includes the dbtoyaml utility to create a YAML description of a PostgreSQL database's tables, and the yamltodb utility to generate SQL statements to modify a database to match an input YAML specification. It also aims to develop data administration tools to supplement an agile database development process.
RainCaptcha is a CAPTCHA class that does not require any image processing extensions (GD, ImageMagick, etc). CAPTCHA was developed to be readable by humans and resistant to OCR software. It generates black-and-white images with 5 distorted letters on them and noise. Its checking algorithm is case-insensitive.
Multi-Sandbox Lua Engine (MSLE) is a modified Lua interpreter which supports creation and maintenance of multiple "100% tight" sandboxes from within Lua. "100% tight" means that the amount of memory used by a sandbox (counting both code and data) is strictly limited, a feature Lua did not offer before.
