Thanks, we'll put that link in the toptext as well.

(This comment was made when the top link was https://www.yankodesign.com/2026/05/31/a-zipper-patent-sat-i.... We've since changed the link to https://news.mit.edu/2026/three-sided-y-zipper-design-0504)

Thanks! let's change the URL to that from https://www.yankodesign.com/2026/05/31/a-zipper-patent-sat-i... and we'll put that link and the video in the toptext.

This is worth doing because I'm about to re-up the thread a la https://qqrl.tk/item?id=26998308.

Can you please not post AI-generated or AI-edited comments to HN? It's not allowed here - see https://qqrl.tk/newsguidelines.html#generated and https://qqrl.tk/item?id=47340079.

Of course, it's impossible to know for sure what was LLM processed or not, but some of your posts (like this one) have been getting classified that way.

I'm sure it's a great place to live and work, but can you please edit out swipes from your comments here, as the site guidelines ask (https://qqrl.tk/newsguidelines.html)?

Your post would have been just fine without that first bit.

Thanks! changed from https://www.ecb.europa.eu/euro/banknotes/future_banknotes/ht... above. I've put the original URL in the toptext.
