Am I my brothers keeper? Culturally, we've just bought into the notion that I'm not your therapist, so as to absolve myself of the responsibility of fixing broken people. But if I don't do it, who will? so I take care of myself first, so that I'm sable to take care of others, but when I encounter broken people, I still try to fix them (as if people are devices like microwave ovens that need fixing) , because we all have to live in a society and hurt people hurt people, so don't over extend yourself, but also do the work that's staring you in the face.
From the description of the product, I think the intention is that the tone is received electrically at the end of a cable run, so receipt of the tone indicates continuity of the speaker cabling. This high frequency has been chosen to ensure that it is low enough to be amplified and transmitted along with the audio content, and is high enough to be attenuated by the tweeters (so little energy is transmitted), and high enough in frequency so that whatever is emitted by the tweeters will be inaudible.

If this is the case, it would sound like there is no need to encode any information on the signal, just it's presence is enough to test the wiring is intact. I'm assuming this is so that if the PA is required for, say, an emergency broadcast, it is fit for purpose.

The presence of a <20Khz signal would imply that it was found that in whatever installation was being used that the bandwidth of the amplifiers or some other filter was attenuating the test tone too much to be received properly, so this bodge was put in place.

They are not as arbritary as first glance as they might appear, related functions often cluster together creating families of opcodes. How many instructions in the family, what circuits and hardware components they use, and other optimization factors influence the arrangement of instructions as well which can determine the binary number the opcode uses.

Okay, fair point, I was not understanding that topological defects are points in solution space that are not path connected to the vacuum solution. I'm learning as I'm going!

Now I also realize that the paper seems to say that the both the ordinary dirac shell solution and their modified shell are TDs, without proving it.

I'd like to work up to proving whether the collapsing modified shell really does homotopy into into a point and then fade away into the vacuum.

But first, I'm struggling with

> nobody would argue that a point charge is a topological defect

It's actually not clear to me that the point mass is not a TD!

Let's try to write the homotopy sending a point mass Mδ₀ to the vacuum solution 0. Let t vary from 0 to 1. Then a possible homotopy is

h(t) = (1-t)Mδ₀

This gives us

h(0) = Mδ₀

h(1) = 0

The problem is that I don't know how to prove continuity of h.

First, I don't know how to compute even the continuity of neighboring Delta functions for t < 1. But that feels intuitively like it should be continuous.

On the other hand, I REALLY don't know how to prove continuity at t = 0, since the function seems to spontaneously collapse from a distribution with a kind of pseudoinfinite value at the origin, into a regular function with the value 0 at the origin.

Using the notation of inner products and test functions, can we prove that it's continuous both for t < 1 and t = 1?

I know that's a bit more technical than we usually get here on HN! I truly appreciate the help!
I recently watched Threads for the first time, and I was scarred. The way it portrays the effects of a nuclear attack was too real and made me feel incredibly depressed for days. It felt almost as if I were looking at a portal into the future, showing how the human race will eventually end.
Few examples.

One time I asked about reading/filtering JSON in Azure SQL. Claude suggested a feature I didn't know of OPENJSON. ChatGPT did not, but used a more generalize SQL technique - the CTE.

Another time I asked about terror attacks in France. Here Claude immediately summarized the motives behind, whereas ChatGPT didn't.

Lastly I asked for a summary of the Dune book, as I read it a few years ago and wanted to read Dune Dark Messiah (after watching part 2 of the 2024 movie, which concludes the Dune 1 book). Here ChatGPT was more structured (which I liked) and detailed, whereas Claude's summary was more fluent but left out important details (I specifically said spoilers was ok).

Claude don't have access to searching internet or making plots. ChatGPT seems more mature with access to Wolfram alpha, latex for rendering math, matplotlib for making plots etc.

Sure, because it's reversible. If they don't like hearing they can always become deaf again.

You're mixing several (valid!) concerns here that I think deserve being addressed individually.

Visa and Mastercard are card brands/schemes/networks, but definitely not issuers of credit cards, and accordingly also not issuers of credit. No fiscal policy is happening here; if anywhere, you'd have to look at banks for that (and it might be interesting, but in my view this has nothing to do with cards).

What they do control to a concerning degree is the ability of merchants to accept payments in the first place, together with acquiring banks. If Visa and Mastercard decide that merchant category x or charity y can't accept payments anymore, that's a big problem.

In my view, this is a task best left to democratically elected governments held accountable through checks and balances, not to private corporations. Of course, these will also have to follow regulations – but sometimes, they go above and beyond (e.g. out of brand recognition concerns), and in doing so end up exporting decisions and policies into distant corners of the global economy that have no political, legal, or economic recourse.

Finally, you've got the concern of market dominance and whether there is effective competition in all relevant markets (e.g. merchant-side in addition to just issuing-bank-side) between the two, and whether that leads to inefficient prices for merchants. But as I've mentioned elsewhere, the biggest chunk for card processing fees is paid back to the cardholders as points in the US, not to Visa or Mastercard.
it might; depending on your goals: microphones color the sound and their limits can be as valuable as their capabilities, in the right context.

see the mics that harmonica players lust after. "You traded the Cadillac for a microphone? ... I can see that."

I believe many sound chips still have ways around any pee-processing they may apply, might check the folks using them for low rate oscilloscope inputs

On this topic, how much should a person trust central repositories of well-known operating system distributions (e.g. Arch, Debian)? I know only trusted people can upload to them, and the only time I've ever heard of malware slipping past them was XZ, but I don't know how much care they take.
You have to think about how your operations interact with other operations you might also do on the random state. Like what if you add one to the state, but someone else subtracts one from the state back to where you started, ooops! Or what if you create a new rng2 by adding one to the state of rng1. Then later you create rng3 by adding one to the state of rng1. Now rng2==rng3. Oops!

That's why I like the orignal idea you described of adding 1 and 2 and advancing each rng. This ensures that both streams are irreversibly altered which should make it very hard to accidentally misuse.
First of all "dietitians" just spout the conventional wisdom and are not known for their acerbic wit.

And yes, I recommend eliminating fruite, vegetables, whole grains, and plant-based proteins. All the nutrients you need are contained in animals. Beef liver, eggs, and sardines are the three most nutrient-dense foods on Earth.

Anyone can simply try this diet for themselves (please give it at least six weeks, but ideally 12 weeks). I promise you that you will thrive.

I mean that here-and-now is an aggregate of discrete attention spans. Without integration these spans are separate "now" without "here". Attention directed to future events is not truly separate from those events (coupling constant unknown), doing away with some conventions about mind-over-matter/matter-over-mind. - When we make plans part of us goes to a future "now" which is not "here" yet. The future already exists in some uncollapsed quantum world which our attention can go to but we don't have a means of navigating our conscious here-and-now to that future unless we construct the path there, which we do in the conventional sense. This means that things which we are able to imagine are not dualistic illusions but real to a different degree than what we have been assuming 'real' is.

To me personally this philosophy makes for a richer and more rewarding inner world.

Computational irreducibility does away with any practical significance the simulation hypothesis could have, and it provides structure to plans-turned-paths-to-the-future. Your attention into the future is one degree of irreducibility, your consciousness is another, and the zeitgeist of our age is a third, resulting in an ego with three shells.

I want to check that I’m parsing this correctly.

Caring about something beyond a typical amount for intrinsic reasons is a neurodivergent marker?

Is this really the HN I grew up with?
It can help reframe personal experiences and past struggles for one, but it can also help gain access to support that isn't available if you're just a "weird nerd". It can also serve to legitimize your struggles to people who think you just need to "stop being so lazy" at whatever you genuinely struggle with by being able to point at a diagnosis.

Yeah, the benefits are a mixed bag and subjective but that's why we should normalize self-dx rather than insisting people have to get a medical opinion to be "validated".

Well, here's the non GPT version of the book, my personal interpretation: From what I remember of Pride and Prejudice the plot involves various women choosing to marry for economic reasons, lust, or love, in a society that gives them little to no economic opportunities outside of marriage and therefore pressures them to marrying for economic reasons.

The protagonist refuses to marry for wealth but in "have your cake and eat it too" fashion, fate rewards her with the love of a wealthy man as a reward for supposedly not caring about marrying a wealthy man.

A character marries for economic reasons and is comfortable but bored in life. Another character has out of wedlock sex and is punished by the hand of fate and miserable.

I'd argue saying it's about "status hierarchies" is not particularly informative.
Though it looks like it's not strictly against https://ideas.lego.com/guidelines , under "PLEASE ONLY SUGGEST NEW IDEAS. NO IDEAS TO “BRING BACK” OLD LEGO SETS." they say:

> Don’t submit product ideas requesting we re-release or “bring back” discontinued LEGO products or themes in their original form, and don’t submit product ideas that are “modifications,” “improvements,” or “expansion sets” to existing or past LEGO sets. If you’re submitting a product idea based on a discontinued LEGO theme or brand (for example Blacktron or Octan), it must be your own new, creative work.

simply because this design predates the official re-release... but given that the official one is from this year, it seems really unlikely they'd run with it this soon anyway.
> not said to be either autistic or schizophrenic (you can't be both at the same time

I've never heard this before and a quick search can't find any evidence of it.

The "over-connected" suggestion did pull up studies like this[1], but that's one effect of one set of genes sometimes associated with autism, and, of course, it was in mice.

I'd definitely like to learn more, but at first impression, a spectrum with autism and schizophrenia at opposite ends seems way too simple a model for human brains.

Not related to “git push” deployments, but absolutely related to the PaaS experience, the team I’m working on is previewing Cloud Native Buildpacks (CNB) which is an open spec in the CNCF for Buildpacks that target OCI.

I agree it's not super likely, unfortunately.

Indeed. The modern web browser is the single most advanced, complex, and highly developed piece of software that 99% of people will ever interact with, and we treat it as a given. Having a highly performant fully sandboxed VM that runs on every system imaginable in billions of devices used by nearly every human on earth is the single greatest triumph of software engineering ever, perhaps only second to the Linux kernel.
After many years of Django development I've settled on what I find the simplest solution. It includes activation of virtual environments when I cd into a directory.

pyenv for installing and managing python versions.

direnv for managing environments and environment variables (a highly underrated package imo).

With those two installed I just include a .envrc file in every project. It looks like this:

layout python ~/.pyenv/versions/3.11.0/bin/python3

export VARIABLE1=variable1

export VARIABLE2=variable2

That's a fair point, multiple models is a potential implementation detail for parallelization - I do think it's fair to assume you are "restarting" the model or clearing context by some means between runs otherwise I don't think it achieves the goal of groomed attention.
WASM without DOM would be like if your operating system said "you can write your code in any language, but if you want to output anything to the screen, you need to compile your code as a DLL and call it from a C program."

For an assembly language designed to run in the browser, I wouldn't characterize DOM access as "just one of many APIs". DOM access is the most universal need in front end programs.
The number of people working on improving AI is relatively small compared to the number of people reselling OpenAI APIs so I don't expect huge improvements in the next 5-10 years. The real value of AI is in ML, but with human supervision and interpretation of results. GenAI is the worst thing that happened to AI, because its coming rejection will reflect badly on the rest of the advances broadly labelled as AI.
I think you’ve really captured the essence of this phenomena in a remarkably succinct way. I do hope that business leaders eventually develop their own capabilities for independent creative thought, rather than being a bunch of mindless also-rans.
It's not specific to deep learning, practically every industry will look at security as a cost just not worth it.

Even the trailer is harrowing with audio alone:

https://www.youtube.com/watch?v=vgT4Y30DkaA

The part where the audio seamlessly transitions from screams into screeching wind, wails, and explosions was chillingly well done in the most dramatic way.
