Donner Party

The Donner Party, sometimes called the Donner–Reed Party, were a group of American pioneers who migrated to California in a wagon train from the Midwest. Delayed by a multitude of mishaps, they spent the winter of 1846–1847 snowbound in the Sierra Nevada mountain range. Some of the migrants resorted to cannibalism to survive, primarily eating the bodies of those who had succumbed to starvation, sickness or extreme cold, but in one case two Native American guides were deliberately killed for this purpose.

One year ago, Danny Filippidis disappeared during a ski trip in New York and resurfaced days later in California — with little to no memory of how he got there.

TIL rabbit starvation is when the body takes in too much protein with not enough fat and carbohydrate. When excessive amounts are consumed, it can put the body at risk for increased levels of ammonia in the blood. Protein poisoning can be fatal because of these increased levels. https://www.healthline.com/health/protein-poisoning https://redd.it/18vy9cv @r_til

TIL: Supercomputers know how to solve EVERY chess ending that has seven pieces or fewer remaining, regardless of position, makeup of the remaining pieces, or possible moves. This information, known as endgame tablebase, is currently 18.4 terabytes in size. https://en.wikipedia.org/wiki/Endgame_tablebase#:~:text=By%20August%202012%2C%20tablebases%20had,solve%20all%20eight-piece%20positions.. https://redd.it/18w5a3c @r_til

Endgame tablebase

In chess, an endgame tablebase, or simply tablebase, is a computerised database containing precalculated evaluations of endgame positions. Tablebases are used to analyse finished games, as well as by chess engines to evaluate positions during play. Tablebases are typically exhaustive, covering every legal arrangement of a specific selection of pieces on the board, with both White and Black to move. For each position, the tablebase records the ultimate result of the game (i.e. a win for White, a win for Black, or a draw) and the number of moves required to achieve that result, both assuming perfect play. Because every legal move in a covered position results in another covered position, the tablebase acts as an oracle that always provides the optimal move.
