Who was known for being a convicted murder and entrepreneur, but also known for inventing what's known as the dancing tree in computer science?
Dancing tree In computer science, a dancing tree is a tree data structure similar to B+ trees. It was invented by Hans Reiser, for use by the Reiser4 file system. As opposed to self-balancing binary search trees that attempt to keep their nodes balanced at all times, dancing trees only balance their nodes when flushing data to a disk (either because of memory constraints or because a transaction has completed).
Ira Einhorn Ira Samuel Einhorn (born May 15, 1940), known as "the Unicorn Killer", is an American environmental activist convicted of murdering his ex-girlfriend Holly Maddux. On September 9, 1977, Maddux disappeared following a trip to collect her things from the apartment she and Einhorn had shared in Philadelphia. Eighteen months later, police found Maddux's partially mummified body in a trunk in his closet. It had been packed with Styrofoam pellets, air fresheners, and newspapers.
