PMD scans Java source code and looks for potential problems like: * Possible bugs - empty try/catch/finally/switch statements * Dead code - unused local variables, parameters and private methods * Suboptimal code - wasteful String/StringBuffer usage * Overcomplicated expressions - unnecessary if statements, for loops that could be while loops * Duplicate code - copied/pasted code means copied/pasted bugs

Wrapper code to start/stop a Java application as a daemon. Daemon is made of 2 parts. One written in C that makes the interface to the operating system and the other in Java that provides the Daemon API.

GNU `m4' is an implementation of the traditional UNIX macro processor. It is mostly SVR4 compatible, although it has some extensions (for example, handling more than 9 positional parameters to macros). `m4' also has builtin functions for including files, running shell commands, doing arithmetic, etc.

The org.apache.commons.jxpath package defines a simple interpreter of an expression language called XPath. JXPath applies XPath expressions to graphs of objects of all kinds: JavaBeans, Maps, Servlet contexts, DOM etc, including mixtures thereof.

java Management Extensions (JMX) is an API that facilitates building management applications that can configure, and perform operations on, a server applica -tion. In general, each manageable component of the server application is re -presented by a Management Bean (or MBean, for short). JMX defines three types of MBeans, of which Model MBeans are the most flexible. Model MBeans provide a way to define MBeans for many different components, without having to write a specific MBean implementation class for each one. However, this power comes at a price. It is necessary to set up a substantial amount of metadata about each MBean, including the attributes it should expose (similar to JavaBeans properties), the operations it should make available (si -milar to calling methods of a Java object via reflection), and other related information. The Modeler component is designed to make this process fairly pain -less -- the required metadata is configured from an XML description of each Model MBean to be supported. In addition, Modeler provides a factory mechanism to create the actual Model MBean instances themselves.

PHP language extension for RedHat Newt library, a terminal-based window and widget library for writing applications with user friendly interface. Once this extension is enabled in PHP it will provide the use of Newt widgets, such as windows, buttons, checkboxes, radiobuttons, labels, editboxes, scrolls, textareas, scales, etc. Use of this extension if very similar to the original Newt API of C programming language.

PHP PECL extension provides possibility to overload operators for PHP objects. At the moment it allows overloading of the following operators: + - * / % << >> . | & ^ ~ ! ++ -- += -= *= /= %= <<= >>= .= |= &= ^= and ~=

The params extension provides userspace equivalent of zend_parse_parameters()

Javolution is the Java solution for real-time and embedded systems. Javolution real-time goals are simple: to make your application faster and more time predictable! That being accomplished through: * High performance and time-deterministic (real-time) util / lang / text / io / xml base classes. * Context programming in order to achieve true separation of concerns (logging, performance, etc). * A testing framework addressing not only unit tests but also performance and regression tests as well. * Straightforward and low-level parallel computing capabilities with ConcurrentContext. * Struct and Union base classes for direct interfacing with native applications (e.g. C/C++). * World's fastest and first hard real-time XML marshalling/unmarshalling facility. * Simple yet flexible configuration management of your application.

Provides a userspace interpretation of the opcodes generated by the Zend engine compiler built into PHP. This extension is meant for development and debug purposes only and contains some code which is potentially non-threadsafe.
