“but it's a must see”

Must-see Numberphile video with Cliff Stoll.

Full comment

this numberphile/Cliff Stoll video is on a different topic, klein bottles... or maybe more the travelling salesman/knapsack problem, but it's a must see. Cliff is a cool guy (whose geewhiz excitement I can only take in small doses but) he's worth following this video

Features the forklift in question.

Full comment

Numberphile did a video a couple of years ago that featured the forklift in question: this video Cliff is a really neat guy. I met and talked to him briefly once (at Dayton Hamvention, 20ish years ago). He's a really, really nice guy.

Example of Cliff Stoll's crawlspace warehouse.

Full comment

It's been implemented to some degree by Cliff Stoll for his klein bottle business. Or rather, he started a warehouse in his crawlspace. Same difference... this video

Shows the little warehouse full of Klein bottles under his house.

> Of course, these days, he's the best dang Klein bottle glass blower in the game. And of course, he hires out the manufacturing. That's why he has (an awesome, little) warehouse under his hour full of them. this video

“Cliff Stoll is the most earnest person I have talked to in the past year, and also one of the most playful and fun.”

Example of earnest and playful person.

Full comment

> Earnestness, for example, is pretty far away from my conception of "playful" or "flirty" or even "fun". Cliff Stoll is the most earnest person I have talked to in the past year, and also one of the most playful and fun. See e.g. this video I think you have a non-standard personal definition of “earnest”. As I understand the words, earnestness and playfulness are completely orthogonal/unrelated attributes.

So in 2015 [1] you said you ordered enough bottles for about 10 years, but you're already running out? That's quite the success story you have there! [1] this video
