Kevin Buzzard just announced the Xena project is organizing a workshop for undergraduate students working on group projects in Lean, and some special guest lectures, September 26th-30th 2022.

Remembering seeing the game Watch Dogs for sale on a Russian site and they translated the title as meaning "Look at the Dogs". Recipe for disappointment.

@Vierkantor magpies love going *sneeze* *camera shutter noise*

Machine translations suck because they can't tell if "bat" means a baseball bat or a winged mammal.
This thought to you by Redbubble "helpfully" translating stuff for me to German. -_-

@anke my fav example of this was sirens in english becoming iirc sirenas in spanish, which turned an announcement of a town's safety features into

'In case of a tornado, the mermaids will alert you,'
