caturopath··on I don't understand quantum physics (2018)
To be precise, Bell's inequality rules out a local hidden variable theory. Pilot wave theories/Bohmian mechanics is an attempt to describe a nonlocal hidden variable theory of quantum mechanics.
caturopath··on In Hilbert space, all things are quantumly possible
Mass isn't close to being conserved. If an electron and positron annihilate, they become two massless photons, for example. You don't need to invoke an expanding universe.

In an expanding universe, energy isn't conserved. (Unless we do the trick we always do with energy and just define it to be conserved https://youtu.be/lCgKTpIzjRk?t=174 )

I don't know exactly why you think this applies to charge conservation. The U(1) symmetry is where charge conservation comes from and it isn't affected by an expanding universe.

caturopath··on In Hilbert space, all things are quantumly possible
So, what I meant to say was that using the computational gadget from physics, none of the branches will violate conservation of charge.

However, my post sucked and I didn't get around to emphasizing that. In quantum mechanics, it's possible for some state to have zero probability, and it's those probabilities that we're talking about everything being possible.

There's also the epistemic side where we know that there's a chance our theories are wrong in any given way. Those can't go to zero based on our model since the whole point is we're not restricting to a model. BTW, I really like your example as a good, clean limiting case.

-------------

I'm sure people have come up with theories that violate conservation of charge, but they'd have to break U(1). I don't know what conservation CPT would break, if any; Noether's theorem shouldn't apply to it as a discrete symmetry.

For example, there's probability 0 of worlds where charge isn't conserved.

This would matter for bigger versions of the same thing. For side-by-side, the aspect ratio is unimportant since you naturally unfold to have two of them.
caturopath··on Aphantasia Beginner's Guide
Think of Beethoven's ninth symphony or a foot massage. You probably don't have the sensation of hearing or of your feet being massaged, you just think about it. You can even do stuff like increase the tempo or decrease the pressure, just like aphantasiacs can turn the Eiffel Tower upside down. They just don't have the experience of seeing.
caturopath··on Kaiser nurses say AI, surveillance are making their jobs and patient care worse
Right, but the article was about Kaiser and I was talking about the thing the article was about.
caturopath··on Kaiser nurses say AI, surveillance are making their jobs and patient care worse
> Increasingly health insurance companies and healthcare providers are intertwined.

Kaiser is an HMO. They are the insurer and try to have their employees, such as these nursing lines, perform almost all of their care. Shifting from one line of business to another is purely internal and can't game Medical Loss Ratio like your scenario.

> they don’t have much incentive to lower total cost because 20% of a larger number means more total profit

There is some bad incentive here for sure. That being said, insurers do compete on price so they lose customers if they charge more than other insurers. Also, regulatory rate review can decide whether they can raise premiums a given amount.

caturopath··on Kaiser nurses say AI, workplace surveillance are making their jobs, care worse
The article doesn't seem to be about replacing nurses staffing their phones with AI. It seems to be about making sure the care they're providing is what the company wants.
caturopath··on Kaiser nurses say AI, surveillance are making their jobs and patient care worse
I'm not sure the for-profit approach is exactly what's to blame. HMOs like Kaiser are legally forced to spend a certain fraction (80% percent for the worst case, more for large group plans) of their premium revenue on medical services. They can't save and pocket the money like a traditional for-profit enterprise.

This doesn't seem like a money-saving measure exactly. The main AIs the article talks about is making sure nurses on their nurses' lines aren't being assholes. I guess this used to be spot checked before so you save on that? Maybe? It seems like they are trying to solve the problem of some of their nurses staffing their nurses' line not treating their patients the way they're supposed to.

caturopath··on California AB 2047 makes 3D printers off-limits to students, educators, business
I'm getting a lot of refusals these days from multiple LLMs on multiple fronts for silly stuff, a lot more than I had for a while. If this is where things are really going, I think open weight models have a big future.
caturopath··on Meta's ships facial recognition on smart glasses
That I don't know if they're a stranger or not. I introduce myself to acquaintances fairly regularly (sometimes annoying them that I apparently think they're so unmemorable) because I'm the opposite of 'I never forget a face'.

I think normal people are more likely to have the experience where they can't remember a name and why/how/where they know someone from. I of course forget things like anyone, but that's unrelated.

caturopath··on Meta's ships facial recognition on smart glasses
Like the poster, I'm faceblind. It isn't the worst thing: I'm not voice blind, height blind, age blind, hairstyle blind, gender blind, features associated with race and ethnicity blind, attractiveness blind, affect blind, context blind, etc., so I'm mostly good at figuring out who someone is. Within one encounter with a bunch of people, I try to note what someone is wearing.

Every once in a while I don't recognize someone and I go through this whole thing of bringing up every biographical detail about them I remember and all the things we've talked about to show that I'm not an asshole who wasn't paying attention in the past. Fortunately, I have a decent memory for such things.

caturopath··on Big tech's anti-labor playbook has come for Wikipedia
My experience with their Norwegian has been fantastic, I'd be shocked if the other Scandanavian languages aren't at least as good.
caturopath··on Big tech's anti-labor playbook has come for Wikipedia
LLMs are great with minority languages compared to almost anything else. Including better than the by the natural language generation employed to use Abstract Wikipedia, which whiffs at relatively large languages like Zulu and Xhosa, let alone many of the rarer languages that popular LLMs speak fluently.
caturopath··on If AI writes your code, why use Python?
Other correctly point out it does matter what language the code is in since the human does sometimes need to read and understand it.

But also, I suspect the article is just wrong. "The hard languages got easy first" isn't true in practice and the impressive examples given are not representative or as magical as the poster makes them out to be.

The takeaway might be right in the end, but the post isn't right in the beginning.

Plants seem to manage it okay.
caturopath··on ChatGPT terms disallow its use in providing legal and medical advice to others
I follow the logic, I'm just not sure the claim is right.
caturopath··on ChatGPT terms disallow its use in providing legal and medical advice to others
> telehealth is much better at recognizing "I can't given an accurate answer for this over the phone, you'll need to have some tests done"

I'm not sure this is true.

caturopath··on ChatGPT terms disallow its use in providing legal and medical advice to others
> Physicians use all their senses. They poke, they prod, they manipulate, they look, listen, and smell.

Sometimes. Sometimes they practice by text or phone.

> They’re also good at extracting information in a way that (at least currently) sycophantic LLMs don’t replicate.

If I had to guess, I think I'd guess that mainstream LLM chatbots are better at getting honest and applicable medical histories than most doctors. People are less likely to lie/hide/prevaricate and get more time with the person.

caturopath··on ChatGPT terms disallow its use in providing legal and medical advice to others
Would be interested to hear a legal expert weigh in on what 'advice' is. I'm not clear that discussing medical and legal issues with you is necessarily providing advice.

One of the things I respected OpenAI for at the release of ChatGPT was not trying to prevent these topics. My employer at the time had a cutting-edge internal LLM chatbot for a which was post-trained to avoid them, something I think they were forced to be braver about in their public release because of the competitive landscape.

caturopath··on Addictive-like behavioural traits in pet dogs with extreme motivation for toys
I'm struggling to understand what the result really is: it seems that some dogs at some point would rather play with a toy than eat or come play with their owner. That seems pretty normal. Is this really "addictive-like"? Why isn't it "really enjoy"?
caturopath··on Swiss glaciers have shrunk by a quarter since 2015, study says
Whenever I try to read up on it, it seems like glaciers are receding at ~2x their without-climate-change rate. That's a huge increase, but it doesn't seem like there's something that a person can experience at a visceral level here that is based on fact and not just preconception.

It's definitely striking, I can't deny that. I crossed the last remnants of an almost-extinct glacier last year that my guide guessed would be gone in 1-3 years: at the beginning of his career it was a real glacer with non-trivial extents, crevasses, etc.

caturopath··on Wikipedia loses challenge against Online Safety Act
Yes, there are unilateral policies and treaties that let the US and the UK collaborate in legal action (going through US institutions to judge them), some of them referenced in https://meta.wikimedia.org/wiki/Legal/Legal_Policies -- a keyword might be letters rogatory

Wikimedia also seems to have a presence in the UK https://wikimedia.org.uk/ that presumably would be affected.

In most cases they might have enough pull to get folks blacklisted by payment processors, but wikimedia in particular might win that one.

caturopath··on Show HN: SQL-tString a t-string SQL builder in Python
For any of you also confused by

    with sql_context(columns="x"):
        query, values = sql(t"SELECT {col} FROM y")
I think

1. this is relying on the `col = "x"` in the previous example

2. columns is a set of strings, so it might be sql_context(columns={"foo", "bar", "x"}) to allow those as valid options. It just happens that "x" is a collection supporting the `in` operator so it works much like the set {"x"} would.

2a. (You might hope that something would convert such a string to a singleton set, but I don't think it does, which would have weird results with a multi-letter string.)

caturopath··on In the Network of the Conclav: How we "guessed" the Pope using network science
Their model had 15 slots spread across three lists, with Prevost appearing on one list in the top spot (and not in the other two lists at all). I am not sure we can conclude a ton about their predictive power.
