Took a while to find on their website but here’s a benchmark vs AWS Aurora:

Seems a bit better, but they benchmarked on a kind of small db (500gb db / db.r8g.xlarge)

Lots of non-chatbot uses in property management. Auditing leases vs. payment ledgers. Classifying maintenance work orders. Creating work orders from inspections (photos + text). Scheduling vendors to fix these issues. Etc.

They say "thus, on average, about two-thirds of cats preferred to sleep on the left side of their body with their left shoulder down", and their image for leftward lateral bias shows this. So I guess leftward means "lying on their left side", not "curling left".

But, they suggest this is because "Upon awakening, a leftward sleeping position would provide a fast left visual field view of objects", which seems suspect. When my cats sleep on their left, it's their left eye that's obscured by their paw, and their right eye that has a better field of view!

> Here, I don't think it's even useful to look at this problem in electronic terms

I always thought this problem was a funny choice for the comic, because it’s not that esoteric! It’s equivalent to asking about a 2d simple random walk on a lattice, which is fairly common. And in general the electrical network <-> random walk correspondence is a useful perspective too

“One could offer so many examples of such categorical prophecies being quickly refuted by experience! In fact, this type of negative prediction is repeated so frequently that one might ask if it is not prompted by the very proximity of the discovery that one solemnly proclaims will never take place. In every period, any important discovery will threaten some organization of knowledge.” René Girard, Things Hidden Since the Foundation of the World, p. 4

Or maybe they do believe this, and entered into trades to express this sentiment. Now, they need the market to correct to what (they believe) is accurate, so they can take profits and free up their capital again.

> These are all special instances of a more general computational problem called the hidden subgroup problem. And quantum computers are good at solving the hidden subgroup problem. They’re really good at it.

I assume they mean the hidden subgroup problem for abelian groups? Later they mention short integer solutions (SIS) and learning with errors (LWE), which by my understanding both rely on the hardness of the shortest vector problem, corresponding to the hidden subgroup problem for some non-abelian groups. I haven't read into this stuff for a while, though

There’s a fun version of this that they have at 7-11 (or 7 & I) there. Probably other convenience stores too. They come in a plastic wrapper that separates the nori from the rice and filling so it doesn’t get soggy. When you pull a little tab, it somehow removes the plastic from in between without messing up the shape. Magic!
