A slot is a rectangle in ice hockey. It extends from the blue line toward the goal. The term is related to the verb “sleutana,” which means “to cut or provide with a slot.” Its meaning as a noun has changed through the years. The sense of “dropping a coin into a slot” appeared in 1888. It also came to mean “to take a position in a slot” and “to fit something into a slot.” These definitions are largely obsolete.
The word “slot” is a late-14c. French word referring to a hollow in the throat above the breastbone. It is also a synonym for “deer track” as it is often a place for a bloodhound to follow a wounded deer. In fact, the word “slot” has more than one meaning. Its original meaning in medieval French was “a hollow depression in the throat.” Its modern meaning is associated with slots, and it is the most commonly used synonym for “deer track.”
While signals are slightly slower than callbacks, they are very flexible and efficient. They cost nothing compared to calling ten functions directly! A signal connected to a slot is about ten times slower than calling a receiver directly. The difference is the overhead involved in locating the connection object, iterating over all connections, and marshalling the parameters. As long as you can avoid the latter three, this method is well worth the overhead.
While it used to be difficult to find a casino with loose slots in a bar or airport, the trend has changed dramatically. Slot clubs opened in Russia in 1992 and were very popular, with the most popular models being Vulcan 777 and Taj Mahal. In 2009, the Russian government banned gambling establishments, and these slot clubs ceased to exist. However, the law did not completely ban casinos from offering loose slots, and slot clubs have been restricted ever since.
