Data structure for dynamic connectivity in undirected graphs. Supports adding and removing edges and checking whether two vertices are connected (there's a path between them) in polylogarithmic time.

Java implementation of augmented red-black trees. Easily maintain custom augmentation information by subclassing RedBlackNode: the base class does the work for you.

NitSpec is a gun shot augmentation controller application which controls gun trigger via servo and calculates projectile fly path automatizing shots. Uses few sensors for calculation. This is meant for air rifles.
