🧵 Thread on beautiful data centers:
MareNostrum 4 (Barcelona SCC): Often called "the most beautiful data center in the world," this facility is housed inside the Torre Girona Chapel, a deconsecrated 19th-century church.
When fully installed, it will have a peak performance of 13.9 Petaflops.

❗️PREVISIÓ: Temps molt més tranquil dimecres, però la setmana tornarà a acabar moguda
👉Precipitacions encara fins ben entrada la nit en punts del litoral i prelitoral de BCN i TGN. Però dimecres el sol i la calma guanyaran terreny, amb restes només d'alguns ruixats al sud.

Democracia de la buena.
El rapero Pablo Hasel cumple 250 semanas en prisión. No le aplican la ley de amnistía. Mientras, hoy el excomisario ha sido absuelto por espionaje, le han levantado medidas cautelares, le han devuelto el pasaporte y ya no tendrá que firmar en el juzgado. La "justicia" en el régimen del 78.
