breve is a 3D simulation environment designed for the simulation of decentralized systems and artificial life. While the concept is similar to existing packages such as Swarm and StarLogo, the implementation, which simulates both continuous time and continuous 3D space, is quite different. It also includes an experimental physics engine, allowing the user to implement real-time physical simulations. Simulations are written in a simple object-oriented language called "steve". Users define an agent's behavior by specifying how the agent interacts with the world at each timestep and how the agent interacts when it collides with other agents. The ultimate goal of the system is to allow decentralized simulations to be implemented quickly and easily while providing a sophisticated set of object classes and libraries to facilitate the construction of advanced artificial life simulations.
tich is a "Today In Computing History" Google Gadget that displays an event in history for each day of the year. You'll find out things like: "What joke did Grace Hopper pull the day after the 'first actual bug' was found in the Mark I?" and "Where did the term 'virus' come from?". It can also be used on your own Web site.
timeplotters is a collection of command line tools for visualizing temporal data. It is especially useful for visualizing data from ad-hoc program logs, helping you to spot patterns and anomalies that you would not otherwise see by just watching how the program works or by looking at the logs with the naked eye. Its input format is tailored to event types typically seen in program logs, and the visualization methods are tailored to the questions typically asked about program performance (e.g. distribution of activity durations).
