Fun! If bi-twin chains are those where +1 AND -1 are prime, I wonder what the longest chain is where either +1 OR -1 are prime. And while we're at it, why not XOR too.

If there haven't been any proposals for a friendly name for the 23 bit holdout it looks like a pair of glasses to me. So perhaps "spectacles" would be a nice one, similar to the spectre of recent aperiodic monotile fame.

Delighted to see my local one in there, with a description reading like it was written by Douglas Adams.

“The Hungry Tree is an otherwise unremarkable specimen of the London plane, which has become known for having partially consumed a nearby park bench.”


I googled it and found that it has a more comprehensive Wikipedia article than some prominent historical figures:

https://en.wikipedia.org/wiki/Hungry_Tree


> with a description reading like it was written by Douglas Adams.

No kidding! From the wikipedia page:

> Consideration was given to listing the bench as a protected structure but was decided against as there could then have been a requirement imposed on the council to destroy the tree to protect the bench


When I saw the name of that one, I immediately though of the Kite Eating Tree[1].

https://oisinmoran.com/ with a few entries that have made it the HN front page over the years.

Reminds me of Gödel, Escher, Bach in which there is a phonograph dubbed "Record Player X", which destroys itself by playing a record titled I Cannot Be Played on Record Player X.


I am equal parts daunted and excited about the size of it. On one hand, of course it's a lot of time (he's said it might the average person 500 hours to complete), and I'm liable to binge. On the other, I imagine there will be some incredible depth to it, and maybe a "little and often" strategy might not be too bad (if possible). Despite adoring The Witness and Braid, I'm still not sure if I'll get this one. Would my life be richer from finishing this or a few hundred films? My money is on the latter.

Btw Patrick's Parabox in full is 364 puzzles (I know this off hand because I left it at 363 for a few months before coming back to finish the last one, and it's one off 365).


This is great! Especially nice to hear as I'd been all to aware of the advice to not rewrite your whole codebase once you raise some money as that's an easy way to tank the company. As a result I have probably erred to much on the type of refactoring he compares this to.

More recently I have been more aligned with the shredding approach. I think one of the reasons that it works that isn't mentioned here, is that often you only really know what's needed after finishing the first implementation and/or using it for a while.

I'm also reminded me of the Japanese practice of rebuilding a temple every 20 years: https://longnow.org/ideas/long-term-building-in-japan/

Ha, thanks.


Some funny related cultural trivia is that often Americans find the hardest thing about integrating into Irish culture is how much we reference the Simpsons in day to day life.


Same as Australia, if you’re a millennial/genx. Only 4 tv channels and one of them was showing endless simpsons repeats in the after school time slot. Almost everyone knows s1-11 references.

Kids these days with their on demand streaming don’t understand the monoculture :)


Absolutely! Australian Millennial year. Grew up watching S2-8 every night over dinner on Channel 10 (IIRC), and I sometimes think I could communicate exclusively in Simpsons quotes from that era.


The span of Simpsons meme literacy is identical to the span of western civilization.


Span? Yes. Density? Not as much. I only say it as I've been surprised on several occasions by American friends living here voicing the same thing. I think it may have been in part due to some fortuitous scheduling making it so that literally every Irish person above a certain age has seen a heap of episodes. That and possibly that there wasn't much else on.


TIL i'm part Irish


Neat! Weirdly sending this article from my phone (Pixel 8) to my browser (Arc) via Pushbullet resulted in an incredibly strange bug that it loads this site instead:

https://www.lindelystables.dk/en/posts/functional-quadtree-c...

Got very confused! I challenge the HN hivemind to figure out what's going on.


Apologies! I think I might have a found an eager redirect on the server. I haven't been able to reproduce, but you're not the first to report it. I hope it's fixed now.


I remember Arc randomly rewriting my bookmarks using some kind of summarization model or something like that, it also sometimes changed the name of downloaded files reinterpreting their names. Maybe it is related somehow.

Well, I guess it was the first AI-first browser, hence all this bs. I uninstalled it months ago...


Yeah that feature was nice at the start then got very annoying. Still like the browser though. Weirdly enough chrome on my phone has been reporting the wrong URLs, usually one I've just been on.
