Ships used to use "chip logs" to measure their speed: they would knot a length of rope at regular intervals, attach a chunk of wood at the end, and toss the wood in the water at the stern (back). The sailors would then count the number of knots that passed through their hands in a given time to determine the ship's speed.
Today, nautical speed is still measured in "knots". The book in which sailors recorded their speeds became known as a "log book" – this is the origin of both "logging an entry" and "computer login".
