Perl Pop3 is a POP3 server fully implemented in Perl. The advantages over other POP3 servers are that it is not a memory hog, and can be used to connect to databases for authentication. Also, its code is easy to extend for any other uses, like POP-before-SMTP and extended logging.
In Balder2D, players control small probes that shoot tiny projectiles with which they try to destroy each other. It features a 2D overhead view of the playing field. Probes may be human or computer controlled. A probe can perform the following actions: rotate, fire projectiles, "stick" to a wall, and push off of a wall. Players may rotate their probes while in flight, but the only way to change the direction or speed of flight is by firing projectiles, which gives a small kick in the opposite direction, or by running into walls or other probes.
e2 elements is a flexible and modular application development framework optimized for embedded systems. Through a component-based architecture and the strict separation of implementation and interface, the framework encourages reuse and improves backwards compatibility. It is portable over a wide range of environments, but with low memory footprint and an emphasis on simplicity. It is particularly well-suited for constrained environments like uCLinux. Dynamic loading of components and statically-linked applications are possible.
PED is a dialogue management system that uses a probabilistic nested belief model to choose dialogue strategies. The dialogue system designer need only supply a set of plan rules to PED as a dialogue grammar with preconditions. Using this grammar, PED constructs game trees (like the one below) to represent the outcomes of the dialogue, so that a dialogue strategy can be chosen for the current turn in the dialogue. PED automatically maintains a belief model by a belief revision process that uses the observed acts in the dialogue. The game tree is evaluated in the context of this belief model. PED is efficient because it uses probabilistic estimates of belief rather than a plain logical belief model.
IronBox Linux is a Linux distribution based on Linux From Scratch and designed for usage in high security server environments. Its main goal is to ensure a stable and secure deploy where patching and system upgrades do not depend on security bugs, but on the task team schedules and the needed features of the system or the software it runs.
