You're probably thinking of the de Broglie-Bohm pilot wave theory, where there are actual particles with determinate trajectories at all times, which are probabilistically guided by a wave. I think they main problem with this idea is that it can't be made relativistically invariant, and so it can only be used for systems with low realtive velocities of its components.

OTOH de Broglie for one of the central ideas in the development of quantum mechanics: he inverted Einstein's idea about photons, which were previously thought to be waves but Einstein showed how they came in particle-like quanta. de Broglie realised you could apply the same thinking to matter, which had previously been thought of as particles, and describe them using waves. Subsequent observation of wavelike dynamics (diffraction) of electrons in the Davisson-Germer experiment got de Broglie the Nobel prize.

A few years ago I started living from an informational website I've built. Now software is just a thing I do in support of my work, and it's so much fun. I feel a much greater sense of novelty and agency building little widgets and fiddling with my own static site generator.

Unfortunately, the whole thing is being threatened by Google AI summaries serving the fruit of my labour while denying me the audience.

It's not very comfortable, its hard edges are unpleasant for the fingers and it feels too thin.

The flimsy cap gets lost easy and there is an endless amount of ballpoint pens you can click, that don't even need a cap in the first place.

Average clicking ballpoint pens have a plastic that's more comfortable to suck, lick and bite.

I always hated them.

Sure, I'm not denying that entropy exists as a concept, that can be used to explain things macroscopically. But like you said, it's origins are statistical. To me, temperature is also a similar "made up" concept. We can only talk about temperature, because a sufficiently large group of particles will converge to a single-parameter distribution with their velocities. A single particle in isolation doesn't have a temperature.

So if they say gravity might be an entropic effect, does that mean that they assume there's something more fundamental "underneath" spacetime that - in the statistical limit - produces the emergent phenomenon of gravity? So it isn't the entropy of matter that they talk about, but the entropy of something else, like the grains of spacetime of whatever.

There are two types of people: the ones that write the code, find the bugs (including hardware ones), find the bad design decisions (including the ones they wrote themselves)... and the ones that complain that they found a swearword in the source code they never see because compilation step.

What are the needs for document keyword extraction, as use cases in industries
by samuellmatthew | 2025-06-16 10:29:57+00:00
I have a tool for automated keyword extraction from documents (PDFs, Word, emails, etc.), but lack of understanding on which industries or customer types it can be the most useful. This I have worked on for the past few years now.

It can automatically extract relevant topics, keywords, or tags from unstructured text: useful for searchability, classification, or even summarization.

So far, I’ve identified some potential areas:

* HR: screening CVs * Legal firms: tagging case files, contracts * Customer support: summarizing and tagging tickets or emails * Compliance teams – scanning documents for risk terms or policies

Maybe something you have from your own experience or current problems can be shared?

I mean it makes sense. Same thing as George RR Martin complaining that it can spit out chunks of his books (finish your books already!!)

As I have pointed out many times before - for GRRM's books and for HP books, the Internet is FILLED to the brim with quotes from these books, there are uploads of the entire books, there are several (not just one) fan wikis for each of these fandoms. There is a lot of content in general on the Internet that quotes these books, they are pop culture sensations.

So of course they're weighted heavily when training an LLM by just feeding it the Internet. If a model could ever recount it correctly 100% in the correct order, then that's overfitting. But otherwise it's just plain & simple high occurrence in training data.

The HP 185A oscilloscope[1], 500 MHz bandwidth, was $2000 in their 1960 catalog[2]. That would be $22,000 in today's dollars. (The brochure doesn't say MHz but uses MC meaning megacycles.) It would be fun to compare the specs to a cheap hobbyist level scope today.

It seems to have supported UTF-8 for at least a decade. Although it went the full-on ECMA-35 route of making that an optional switchable character set.

There was an issue back in 2016 where, ironically, it was coming up in Latin-1 mode with everything else around it talking UTF-8, and there have been other similar impedance mis-matches over the years. But they seem to hinge on it actually having UTF-8 support.

Mass Hysteria is seriously dangerous. A few years ago I've seen a full room of people applauding Military for ordering more tanks. ("Enough to have those shot down by Russia in the calculation"). And young German politicians being proud of it. They even said publicly "The best outcome of the Ukraine War would be reinstallment of the old German-Russian border."

Germany has the potential to go full Nazi again... And the population is mostly crazy in a scary way "We need sirens", "We need bunkers", "How can I make my pupils go for a career in the army"...

Instead of of investing time into making a mesh network. I'd like to see more energy spent on preventing real dangers. If people don't start going against the real troublemakers, loss of internet will be very low on the list of problems of the future.

And still nobody I've ever seen in public speak or comment about climate has ever read any paper on atmosphere physics... Before you build a mesh network against climate change, people should better read at least a few papers about atmosphere physics first.

> "requires a fully attentive driver and will display a series of escalating warnings requiring driver response."

I understand the reasoning behind it, but watching the video () of the test shows that the car did not warn the driver, and even if it did it was speeding too much leaving almost no time for a driver to respond

Oh fun, we were wondering where all the traffic was coming from. :P

After finding it 5 or so years ago, NESDev rapidly evolved into my full time hobby, and I couldn't be more thrilled. The community is full of knowledgable nerds, and for a 40+ year old console (... that statement that is distressing on many levels) we're somehow still discovering new things daily.

Right now I'm researching esoteric behavior of the lesser known Famicom Disk System, whose disks are rapidly being lost to time, and which is still quite tricky to emulate properly. Because I can't write my own disks yet[0], that currently means doing fun things like running out of console WRAM while I switch from my devcart to the "RAM Adapter" (which plugs into the cartridge slot), then communicating with my hopefully still running program via an arduino plugged into the controller port. It's wild. :D

[0] Not for lack of ability but a lack of "spare" FDS disks I'm willing to overwrite. I want to study the ones I have, not clobber their contents.
LLMs Are Not Magic: Building Deterministic Agents with Lyzr AI
by fidhaa | 2025-06-16 10:33:41+00:00
LLMs are powerful, but unpredictable. Prompt a model twice and you often get two different answers. In real-world systems, this isn’t just annoying and it’s unacceptable. We need deterministic, testable AI behavior. I’ve been building agentic systems using Lyzr AI that remove the guesswork: agents with clear goals, defined steps, and consistent outputs. No LangChain maze. No magical thinking. Just reliable automation. Here’s a working demo of a deterministic agent I built: https://v0-deterministic-decision-ui.vercel.app/ — would love your thoughts on whether this approach is the way forward.

Perhaps, but unless one of them is Walt Disney, I've never heard of them - therefore their fame does not impact my valuation of their work. I can see myself spend 50 bucks on a (to me) unknown piece of art because it is pretty. Spending more would require an additional connection - fame of artist, depicts something dear to me, seems like a good investment, etc. etc... only being pretty isn't enough.

Why on earth can't this be done by normal testing agencies? Why do things like "Tesla Takedown" have to participate in it? Even if the test was 100% legit, that connection to mere protest movements taints it immediately. It's like when oil companies publish critical research on climate change. Or Apple publishing research that AI is not that good and their own fumblings should not be seen as a bad omen. This kind of stuff could be factually completely correct and most rational people would still immediately dismiss it due to conflict of interest. All this will do is flame up fanboys who were already behind it and get ignored by people who weren't. If real goal is to divide society, this is how you do it.

There are far more than two types; all of the most effective programmers I've ever worked with can do everything you mentioned and write professionally.

If we have to boil it down to two types, however, I'd split it as "people who think they can do everything themselves and only the code matters" and "people who build effective teams capable of far more than themselves solo", and it's the second group that does the most impressive things. Being professional and respectful is quite beneficial for that group.

There is a decent labour savings to be had in code generation, but under strict guidance with examples.

There's a more substantial savings to be had in research scenarios. The AI can read more and synthesize more, and faster, than I can on my own, and provide references for checking correctness.

I'm not confident enough to say that the approaches being taken now have a hard stopping point any time soon or are inherently bound to a certain complexity.

Human minds can only cope with a certain complexity too and need abstraction to chunk details into atomic units following simpler rules. Yet we've come a long way with our limited ability to cope with complexity.
by crowie | 2025-06-16 10:36:57+00:00
Gotcha, but I didn't mean it in that way. What I meant is, that problems like the case-study ones don't need a revolutionary nor an original answer which would require growth, they can be solved with old solutions which I would assume would be in some way embedded into the learning dataset of these models. Yeah, the scope of the problem is bigger, but the correct answer should come down in any case to a correct implementation of the known algorithm. The thing I'm asking is what causes the hindrance which prevents these AIs from performing in appropriate ways given old problems and old solutions.

Why not both? Ebikes are obviously highly useful in cities, but not so much for longer distances in the countryside, also problematic in winter up north. There will always be need for private car ownership for areas that can't be effectively served by public transport (and obviously public transport itself should also be electric powered).

Just electrify everything and let people choose what mode of transport fits their needs and wallet. I barely use my car in city, but absolutely need it to visit my relatives who do not live within reach of public transport.

Ignoring a stop sign, not even slowing down, thats a major safety flaw.

I am wondering if there is a safety certification body for self driving technology. If not, one is needed because consumers can't be expected to be aware of all the limitations of the latest update they have installed.

There must be basic safety standards these systems need to meet, a disclaimer can't be the solution here.

This has done the rounds on other platforms. A couple of important points:

- the failure here is that the car didn't stop for the bus on the other side of the road with the extended stop sign. (Obviously a kid running out from behind a car this late is fairly difficult for any human or self driving system to avoid)

- the FSD version for the robotaxi service is private and wasn't the one used for this test. The testers here only have access to the older public version, which is supposed to be used with human supervision

- the dawn project is a long-time Tesla FSD opponent that acts in bad faith - they are probably relying on false equivalence of FSD beta vs robotaxi FSD

Nevertheless this is a very important test result for FSD supervised! But I don't like that the dawn project are framing this as evidence for why FSD robotaxi (a different version) should not be allowed without noting that they have tested a different version.

I keep waiting for the day when people realise that IP law has been used and abused and thanks to Disney extended out for many, many lifetimes and all manner of dirty tricks/hacks to keep the late stage capitalism profit engine going.

I 100% agree that if an LLM can entirely reproduce a book then that is copyright infringement, overfitting and generally a bad model. I also believe that in this case, HP (and other popular media) is overrepresented in the training data because of many fan sites/literal uploads of the book to the Internet (which the model was trained on). I believe that any & all human writing should be allowed to be used to train a model that behaves in the correct way so long as that writing is publicly available (ie on the Internet).

If I watch a TV show that someone uploaded to Youtube, am I committing a crime? Or is the uploader for distribution?

I also find it hilarious how many artists got their start by pirating photoshop.

> for example §12.2 of Wald, and problems 1 and 4 at the end of chapter 12

Literally the first paragraph of problem 1 states my exact objection.

"Since an observer outside a black hole does not lie within the causal future of the black hole, such an observal literally cannot "see" the black hole. As is apparent from Figure 6. 1 1 , an observer looking at a region where gravitational collapse has occurred would, in principle, see the collapsing matter at a stage where it is just outside the black hole."

What I can't understand is how people can smoothly ignore it and calculate something that is going to happen after infinite time passes on Earth. Because those things will literally never exist, because there's simply not enough time anywhere in the universe outside of any event horizon. For the points on event horizon there's no causality line that crosses our future and there's no simultaneity line (however you define it) that crosses our future. It just won't happen, ever, in any practical sense.

> The practical sense is the binary-merger waveforms detected at LIGO, Virgo, and Kagra, which were emitted in the detectors' (and humanity's) past lightcones.

Aren't those waveforms just in agreement of theoretical prediction of what happens as the matter approaches event horizon? Because we can't have any information about it crossing it. I don't have a problem with that part. I have a problem with the part that's theorized to happen after those signals get stretched, red-shifted and stopped by gravitational dilation.

> The curve of every part of a rock chucked through a black hole horizon ends inside the horizon.

Sure at t(Earth)=infintiy.

> Coordinate divergence is not the same as curvature divergence, and different systems of coordinates on a single arrangement of mass can diverge at arbitrary radial distances, including very very large ones.

Curvature is not the only real thing. Time, which is a coordinate is also a very real thing and when it diverges to infinity at any finite point for any observer, we can't just sweep it under the rug with a coordinate change.

> "Does the ringdown overtone of a merger of two black holes encode any of the accretion history of each black hole?" is a physical rather than philosophical question and is an avenue for testing solutions of the Einstein Field Equations (including approximate ones solved numerically) against astrophysical data.

I have absolutely no problem with that. What I have problem with is postulating that anything happens (from our point of view) in that observed region of space after the ringdown overtone of a merger happens. In my opinion when the signals get too faint and redshifted for us too observe nothing ever happens there, because time there physically nearly stops for us.

For the past few years I have had difficulty working out in the yard, and then in 2018 it got harder and harder to breathe. After many tests, it was a CT scan that showed Emphysema, and scarring in my lungs. I quit smoking 8 years ago, but the damage has been done. I got to a point I couldn’t catch my breath and was coughing so hard I thought the top of my head would blow off; nothing was really working to help my condition. Finally, I started on the COPD formula, and with the help of this treatment, I’m active again. Its effects on emphysema are amazing; all my symptoms gradually faded away. I breathe much more freely now and no longer need my oxygen cylinder! Google uinehealthcentre. net to get this formula. I'm surprised a lot of people with COPD/emphysema haven't heard of the formula.

As a foreign English speaker, it's a huge pet peeve is when people use acronyms without having used the full sentence before. Especially when the acronym is already a word or expression and looking it up just returns a bunch of useless examples (oh!). Eventually I'll find out the meaning (other half), and it always turns out they only saved a total of six or seven letters, which can be typed in less than 0.5 seconds, but in exchange they made their sentence more or less incomprehensible for a large group of people.

> You don’t obsess over one thing. You move lots of little things forward. No grand initiatives. No reorg. Just constant, low-key, under-the-radar nudging in the right direction.

It's not terrible advice, but it scales less well than the writer thinks. To really scale, you:

1. Engage with the right challenges (large or small)

2. Invite others into the process, celebrate their successes etc

3. Coach others to start from #1

Perhaps its organisational scope isn't much bigger than the team, but to my mind, the article doesn't go far enough beyond #2.

Do it, and you're the best kind of leader, one that makes other leaders. That's what scales.
