ARS (Autonomous Robot Simulator) is a physically-accurate simulation suite for research and development of mobile manipulators and, in general, any multi-body system. It is modular, easy to learn and use, and can be a valuable tool in the process of robot design, in the development of control and reasoning algorithms, and in teaching and educational activities. It will encompass a wide range of tools spanning from kinematics and dynamics simulation to robot interfacing and control.
netstat-monitor is a commandline tool for monitoring network connections. Its output is similar to the output from the netstat command with the options "netstat --inet -alp". Netstat-monitor can be left running, though, and will report new connections as they are made. Also, filters can be created to limit what's displayed to just what's unexpected or interesting.
irked is an IRC client that runs as a daemon accepting notification requests as JSON objects presented to a listening socket. It is meant to be used by hook scripts in version-control repositories, allowing them to send commit notifications to project IRC channels. A hook script that works with git, hg, and svn is included in the distribution.
Metakit is a small, portable database library using a hybrid relational / hierarchical data model with a column-wise internal storage format. For C++, include a single header file and 125 kb DLL or statically link directly. Ideal for desktops, embedded systems, smartphones, and PDAs. Bindings for Python and Tcl. A very mature, stable code base.
The psycogreen package makes it possible for psycopg2 to work with coroutine libraries, using asynchronous calls internally but offering a blocking interface so that regular code can run unmodified. While Psycopg offers coroutine support, the main module is a C extension that cannot be monkey-patched to become coroutine-friendly. Instead it exposes a hook that coroutine libraries can use to install a function integrating with their event scheduler. Psycopg will call the function whenever it executes a libpq call that may block. psycogreen is a collection of "wait callbacks" that can be used to integrate Psycopg with different coroutine libraries. psycogreen is currently mainly useful for integration with gevent.
