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.

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.

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.

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

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 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.

Ahh I wish I had gotten the chance to interact with new math majors more often. In grad school most of my students were engineering majors. I'm not super likely to end up back in academia. My published research is...sparse. I have post-doc opportunity but it's not the greatest, and the route to life stability is not so clear. Are you a math professor?

when people say "infinity is not a number" they generally mean aleph-0

Sure, maybe. I think saying "infinity is a number" is wrong regardless. I'm happy with aleph-0 being a number, and I'm happy with it having a label of infinity. I'm just not happy with treating infinity as a single thing. We're totally on the same page in every way that matters though. I'm also certainly with you on questioning Retric's comment for a number of reasons, haha.

edit: Actually...I'm not so sure they mean aleph-0. I think frequently they mean the infinity of the extended real line. Maybe it depends on the context of the conversation.

There is no bijection between the natural numbers and the power set of the natural numbers. When talking about bijections to study the sizes of sets, there is clearly not just one infinity. Also consider the extended real line, this makes infinity a perfectly good number as well in a different way.

My point is that infinity is certainly not an individual number. It represents quite a few concepts, all of which have some number like qualities.

For 1, I just use latexmk. I honestly assumed that was standard but I guess not? It comes with TeXLive anyway. For the rest, I use Zotero with betterbibtex and with both that and LaTeX in general I use the more recent biblatex instead of bibtex.

This won't fix everything you've mentioned, but I feel like I generally have a lot fewer issues than what your comment would suggest.

This is less a discussion of the law it self and more a discussion on whether actively breaking laws directly on HN is acceptable. Framing it properly makes it much broader than simply a discussion on this particular law.

I'm a mathematics PhD. All of my PhD work was done in Julia. I'm happy to work in any other language. A sample of my Julia code can be found here [1], and more can be shared in a video chat (my collaborators don't want some of my code public yet).

I'm interested in working with a team where my mathematical background could come in handy, but the problems we solve do not need to be math. I'm happy to work on anything.

The heuristic is that the average of an interval is the middle. If you know nothing about it other than you're at some point on the time interval, assuming you're at the middle time is a good prior.

When you know more, you certainly should adjust. For the job example, you might think "how long have I usually stayed jobs that have lasted least two months?", "how long do people usually stay in jobs if they make it through the first two months?". Generally speaking, Bayes' theorem is the technical answer to "how do you adjust". Not that I ever actually do that...but I think it's the technically correct answer.
