METSlib is an object-oriented metaheuristics framework in C++ designed to make implementing or adapting models easy. The model is modular: all the implemented search algorithms can be applied to the same model. METSlib implements the basics of some metaheuristics algorithms, such as Random Restart Local Search, Variable Neighborhood Search, Iterated Local Search, Simulated Annealing, and Tabu Search. For each algorithm, you must implement an objective function, a neighborhood (move manager), and some moves. Tabu Search is one of the fastest ways to generate near-optimal solutions to a wide range of hard combinatorial optimization problems.
Infonomix is a project management system similar to Trac, written in PHP and using XSLT. It is designed more for professional services tasks, like graphic design and Web development. It also keeps track of time using a time clock system, and time can be assigned to tasks, projects, or clients.
BART Tracker reports on arriving San Francisco area BART trains in real time, using a system tray icon. It uses BART's new "Estimated Arrivals" or "BART System Status" feature, which reports on the current up-to-the-minute status of arriving trains at every BART station. It requires Java 6.
XPTracker is a radical alternative agile planning tool aimed at keeping out of your way and making sure you can see the stuff you care about at a glance. Included in this tool is a very advanced search system based on Lucene, an easy-to-use planning system based on Queues, and a customizable reporting engine (with burndown/scope creep charts) called Timelines.
