Guess I'd better say a few things. First, I deeply appreciate that so many on Hacker News have come out for this. Enough to awaken me from a sound sleep on a Tuesday evening! I don't really care that much about selling Klein bottles over Amazon - it's mainly to reach parents over the holidays. But I do wish that Amazon would do something about this kind of thing. Finally, I"m very low on stocks of glass Klein bottles…

Don't buy this guy's klein bottles, they're a scam - they're only THREE dimensional! Such a rip off. How am I supposed to store a ŷ̶̺̎͌͐̿̽̊́̕ŏ̶̗̈́̓̍̎̃͠g̶̝̺̜̜͋̿̚ͅ-̷̧̛̈́̔́s̷̰̀͌́̈́ơ̷̝̭̫͛́͘ẗ̴̹̱̖̥́h̸̡̡͙̻̀o̸̹̘̾̀͗̇̕t̵̗̠̄̽̈́͑ḧ̵̳̰̩̲͈̜͉̝́́͌͐ in this thing?

Now you've got me wondering if it'd be possible to build a 4D klein bottle by animating a 3D shape.

I imagine you could, and that it might not even be that exciting... Since a Klein bottle is just a cylinder with its ends glued together a particular way, I think one way to sweep out a Klein bottle through time would be to have a rubber band split into two, then have each band travel along a trajectory that brings them back together with the correct orientation. The self intersection is easily avoided by having one…

I went cold turkey on Amazon a few months back; the only thing I've kept is the TV subscription. What I realised is that it was just a dependency because it was so easy to search for and buy stuff. Nowadays I'll buy from a smaller shop if I need something, but it's more likely that I think "do I actually need this?" and say "no."

Also, Walmart.com has similar prices and selection. Free shipping is $35 though. I’ve had much better results with Walmart packaging and shipping lately.

"Amazon has now become the Alibaba of the west" Alibaba is much better than Amazon about seller verification. Look up, say, "PC power supply". On Amazon, you're lucky if you get the address of the seller and a product image. Alibaba gives you multiple detailed pictures of the object, including its data plate. You get the full address of the seller, and whether it's the manufacturer or a reseller. There's usually a pi…

Alibaba & Aliexpress _do_ have a clone problem, but the notable distinction is that they don't aggressively comingle listings like Amazon does. This means for some common consumer items (fidget spinners, etc.) you'll find a hundred listings with identical images, slightly varying descriptions, and different factories, but you can easily choose which seller to buy from.

Hey Cliff, I just have to say thanks. I read the Cuckoo's Egg in the early 90s and while I was already interested in computers, the idea that there were "networks" of them out there... well... it blew my mind. I immediately went to my school librarian and said I wanted to try to connect computers together, or try to dial-up to library information services, etc. We started learning together. You were a huge inspiratio…
