gtkaml is an XML syntax and parser that extends the Vala.Parser and transforms all your tags into a valid Gtk+ UI class. It features a casual XML syntax for describing the way Gtk widgets are laid out in a (new) custom widget you're creating. Code "islands" (written in Vala) are used for widget signal handling and other methods/signals/properties that you're introducing. It doesn't depend on an external library at run-time, and it is much more readable than the usual UI boilerplate.
OpenAL Soft is a cross-platform implementation of the OpenAL 3D audio API. It's based on the open-sourced Windows version from openal.org. It provides capabilities for playing audio in a virtual 3d environment. Distance attenuation, doppler shift, and directional sound emitters are among the features handled by the API. More advanced effects, including air absorption, low-pass filters, and reverb, are available through the EFX extension. It also facilitates streaming audio, multi-channel buffers, and audio capture.
vov (Vov's Obsessive Von-neumann) is a tool that emulates the behavior of a von Neumann machine. It is basically an interpreter that reads files in the form of memory assignments and executes the encoded instructions. The vov's instructions allow you to perform simple arithmetic data manipulation. It is a very useful tool to see if your programs work and how. You can run a vov program from a file as you would any other shell, Perl, Python, or Ruby program.
Python bsddb3 is a Python module that provides a nearly complete wrapping of the Oracle/Sleepycat C API for the database environment, database, cursor, sequence, and transaction objects, and each of these is exposed as a Python type in the bsddb3.db module. The database objects can use various access methods: btree, hash, recno, and queue. It has complete support for Berkeley DB distributed transactions, and complete support for the Berkeley DB Replication Manager and base replication API. The goal is to mirror most of the real Berkeley DB API.
xTests is a small, simple, lightweight, portable unit/component testing library for exercising C and C++ libraries. It relies on no platform-specific or compiler-specific constructs and doesn't require pre-processing of your source code by scripting languages or use macros to create secret classes that use Schwarz counters to register test cases. It relies on you to simply code what you want, and nothing that you don't want.
