I'm a Web developer, and I did hand-code the Dijkstra path-finding algorithm recently. Granted, it's not common, and I didn't do it from memory, but at least I knew what to Google. I needed to represent the shortest path between nodes on a map, so I needed the internal data from the algorithm, thus the need to whip out my own version.
