Magic: The Gathering Is Turing Complete
From Alex Churchill:
In the discussion on this site I assemble a Universal Turing Machine from Magic: the Gathering cards.
But doesn't Magic involve the players making lots of choices?
Normally, yes, it does. But occasionally in normal gameplay you get a sequence of three or four events in a row that are forced to happen by the cards and the rules of the game. The machine below just extends this idea to millions of forced choices in a row.
The idea of my Magic Turing machine is that the players do nothing at all, except when the game offers them a choice.
Once the in-game "machine" has started, processing continues without requiring any choices from the players, with one category of exceptions: Some of the cards in the machine say "You may [do X]. If you do, [Y happens]." In these cases, the machine arranges that the players will be able to do X, in precisely one way. It just requires the players to always choose to take the game up on any options they're offered... (cont'd)

New incremental encoder IERF3 L from FAULHABER
FAULHABER is expanding its product range with the ultra-precise incremental encoder IERF3 L. Thanks to the optical measuring principle and state-of-the-art chip technology, the device offers the highest resolution, excellent repeatability, and outstanding signal quality. In typical applications, the positioning accuracy is 0.1° and the repeatability 0.007°. This makes the encoder the perfect solution for high-precision positioning applications in confined spaces.
