Simone Giertz (previously), a roboticist/satirist/artist/youtuber, has announced that she has a brain tumor the size of a golf-ball behind one of her eyes; it is operable but she could experience longterm vision-loss, paralysis, or cognitive impairment. Her video announcement is brave and funny and moving, and as one of her ardent admirers, I am certainly pulling for her. (via Four Short Links)
