You're welcome, Colin! Across the decades, I appreciate the smiles and advice from Hacker News. How'd I ever reach 75 years old?
You're only 10 years older than me, and I'm hoping to be as active and engaged as you are for a long time to come ... you are a fantastic role model, especially with your interaction with, and inspiration of, the younger generation.
Long may it continue, and I hope to take you up on your invitation to visit again.
He wrote "The Cuckoo's Egg" which is a riveting tale, capable of entertaining nerds and non-nerds alike.
He sells glass Klein Bottles, huge, medium, tiny, earrings, and more.
He's given a TED talk: https://www.youtube.com/watch?v=Gj8IA6xOpSk
He's brilliant, bonkers, and wonderful company. I spent a fantastic morning with him early last year (2024) and it was brilliant fun. I will for many, many years treasure my signed Klein Bottle and my signed copy of "The Cuckoo's Egg".
Thanks Cliff
