MW is a low footprint embedded UI framework core intended for use on very limited systems. It embeds the JPEG, Freetype, and Cairo libraries, so it only depends on X. It should be fairly portable, as the only thing you need is to create a window on every platform and manage the events.
Class::EHierarchy is intended for use as a base class for custom objects. The objects need one or more of the following features: orderly bottom-up destruction of objects, opaque objects, class-based access restrictions for properties and methods, primitive strict property type awareness, and alias-based object retrieval.
autofwd is an automated firewalling daemon intended to block hosts performing unwanted acts. While it was designed to be used to thwart hosts running dictionary attacks on logins (of any service), it can be used for just about anything. The external commands it runs are configurable, allowing you to take additional actions against offending hosts such as running an nmap OS fingerprint before firewalling, or just silently logging the event.
The Paranoid modules provide a number of routines that are intended for use in strict and taint-safe scripts. The modules cover a variety of tasks from command-line argument parsing to process and network management. All of the modules use a debug trace framework for diagnostic output that is easily used and extended for application code as well.
libphidgets is a user-space access library for the Phidget devices. It provides a generic and flexible way to access and interact with the Phidgets, and comes with all the advantages of a user-space library. It is based on libhid (which is based on libusb), thus it requires no HID support in the kernel. Furthermore, it aims to support all operating system supported by libusb/libhid: Linux, BSD, OS X, and Windows.
mass is a program that lets a system administrator execute programs on some set of machines as root. It uses SSH, scp, sudo or su, pings hosts before attempting to scp to them, retries failed hosts, works well with ssh-agent (but also handles SSH password or passphrases) and in general makes life easier whenever there's a need to do some operation on many machines. It works on most Unix-like OSes.
pgAdmin III is an administration and management tool for the PostgreSQL database and derivative products such as EnterpriseDB, Mammoth PostgreSQL, Pervasive Postgres, and SRA PowerGres. It includes a graphical administration interface, an SQL query tool with grahical EXPLAIN, a procedural code editor, an SQL/shell/batch scheduling agent, Slony-I management, and much more. It is designed to answer the needs of most users, from writing simple SQL queries to developing complex databases. The graphical interface supports all PostgreSQL features and makes administration easy.
