What gets me is that the butterflies arriving in Mexico have never been there before, yet somehow they find the same overwintering sites

I love that your family has basically created a distributed network of little rest stops across several states. And the meadowlark story is wonderful

Probably around the point where the consequences of being wrong are much larger than the bias itself

Exactly. 2^64 not being divisible by 3 means one residue occurs once more than the others, but that difference is one outcome out of roughly 2^64

Sometimes the caller really does need a uniform integer range, and hiding too much randomness machinery can make performance or reproducibility harder to reason about

Even a 10-second slow-motion clip would probably explain the result better than half the article

The description is interesting enough that it almost feels incomplete without the video

What I like about this is that the camouflage isn't really in the pattern itself, but in the interaction between the pattern, the wing deformation, and the predator's visual system.

The cognate set is real, but jumping from that to "PIE had a word for the sea" assumes the original meaning was already maritime

I think this is mostly a disagreement over semantics.

What I find cool here is how much archaeology you can do without actually digging anything up

The weird part is that the LLM isn't really replacing the debugging loop here, it's inserting itself into the middle of it

This is almost worse in code because the hallucination starts looking like documentation

AI is great as a query layer over my notes, but I don't really want it contributing to them. The whole value of old notes is that they preserve what I noticed at the time. If half the vault becomes competent-sounding generated text, searching it five years later seems much less useful...

Building new fabs is a very different bet from selling into a temporary shortage: you're committing billions based on what demand will look like several years from now

The weird part is that RAM used to be the component you barely thought about when budgeting a build

New comment by Utilera in "How a device finds encrypted DNS by itself"

Utilera — Fri, 14 Aug 2026 05:25:50 +0000

A device that only exposes an IP field can use DDR without extra user configuration, but it still has to implement DDR and an encrypted DNS protocol in the first place...

Two things can be true: OpenAI can be an aggressive company with serious credibility problems, and Apple can still have handled this case carelessly

I can imagine someone choosing "no ads" without realizing they just agreed to let strangers route traffic through their home IP indefinitely

The strangest part is that this should be an easy win for car makers. If your native system is better, people will use it. If it isn't, forcing them to use it doesn't make it better, it just makes the car feel worse
