Did you know Evi Nemeth (well-known author)?
Evi Nemeth was the author of the quintessential book on system administration (UNIX System Administration Handbook ), and an intelligent and encouraging woman in a field dominated by males. She has been lost at sea. Here's an article with a few more details.
I hardly know what to say. She retired a few years ago (according to the article, she was 71), and went off to live on her boat (not the one she was on in this case). She was a remarkable woman, and I'm sad for anyone who didn't get to know her.
The article says there's still hope. Somehow, I have my doubts.
I'm very sad.
