oh, interesting, I assumed the data came from interruptions (that seemed obvious) but I'm surprised you had some specific negative measurements. How do you decide the magnitude of the number? Just counting how long both parties are talking?

I assume 0 delay is the minimum here, and a median of 0 means over half of the data are exactly 0.

Yeah, I recently upgraded to the 9a from the 4a for $250 USD and am still really enjoying Pixels. I might just be out of the loop on what's available, but I can't imagine many other phones at this price are competitive.

Yeah, it was a pretty big change actually. You're right though, the conversation didn't change much even as access to healthcare did change.

vcxy — Wed, 26 Jun 2024 04:36:44 +0000

I'm an American mathematician and have always allowed the codomain of a random variable to be any measurable space. I haven't noticed anyone mention random elements. I don't work in probability though, so maybe people directly in the field care more.

I didn't know what a duvet was until I was an adult. Grew up with sheets and quilts in Appalachia.

New comment by vcxy in "A muon collider could revolutionize particle physics, if it can be built"

vcxy — Fri, 29 Mar 2024 20:42:59 +0000

Yeah, that seems true and it's basically the value proposition I bring to my work.

Interesting way to look at it. Your description of what physicists are experts at matches my math PhD pretty closely. I focused on mathematical modeling. I now work with a bunch of physicists, so I guess that checks out.

You don't think increasing pedestrian fatalities could be linked to people choosing to walk less? I've certainly noticed in my area that drivers have been much more aggressive since the pandemic started and I walk less because of it.

The article says that biking increased and walking decreased. I don't think I can explain those things simultaneously with just "well we were in a pandemic during that time."

I'm not sure why this article would prompt you to call out bike lanes.

> there’s a noticeable rise in biking trips while pedestrian activity is dwindling as a portion of overall trips.

Beyond that, this seems highly relevant:

> Alarmingly, pedestrian fatalities rose during this period

Maybe we haven't actually made any walkable cities

Out of curiosity, not disagreeableness, which tools are those?

> CCNOT and Hadamard are universal logic gates with which all (?) quantum functions/transforms can be approximated.

CNOT, H, S, and T are universal for approximating any quantum operation.

That's interesting. I thought it was obvious that ADHD does exist because it's just a constellation of behaviors that some people indeed do exhibit. I feel like we agree completely on the base facts and somehow have arrived at opposite conclusions.

I wouldn't say it's a nitpick. Rationals are fractions of integers, not just any fractions at all. Rationals are _examples_ of reals, but it's bad pedagogy to say "fractions, which are called reals" because it sounds like the authors are giving a definition of reals. While they technically did not say this was a definition, it is sloppy.

It's bad pedagogy. But it is also technically incorrect. You can have fractions with complex numbers.

It's a funny thing. I think what you're saying is exactly right from the standpoint of a dev. As a mere consumer, if you support Steamdeck via Proton, then it sure feels to me like you're supporting Linux, but I get why you wouldn't officially say that.

"Roll a D20 and if you get 1 humanity as you know it will be destroyed in your lifetime" seems bad. Why do you consider 7 or 8 percent low?

New comment by vcxy in "Ask HN: What would it take for an AI to convince us it is conscious?"

vcxy — Sat, 18 Feb 2023 14:55:57 +0000

I think drewcoo's point was that "having a conscience" and "having consciousness" are not the same thing. They were pointing out that the wrong word was used with a joke.
