> It calls for an entirely different kind of robotic perception, feedback, and control.

Nearly every surgeon used advanced robots to assist with surgeries. My uncle does kidney transplants and he uses robots, so do most surgeons.

For robots to be developed, someone must pay for it. Doctors get skill++ with the surgery robots. There may be vasectomy robots that assist with circumcision, or some actively being developed that doctors would pay for. That would be a far more interesting development than changing diapers. Unless extremely competent and skilled people ( +1000/hour) need them for their work, they won't be developed, so I don't think a diaper changing robot is being developed.

It's actually kind of funny how React devs quite literally don't know how HTML or JavaScript actually works (let alone HTTP or TCP/IP). React is an absolute trash-heap of abstraction that just reinforces its dominance because of popularity, similar to Java in the early-mid 2000s.

It's the definition of sunken cost fallacy: I mean, heck, I genuinely believe React is garbage, and yet I use it for just about every project because of its ecosystem and lazy "npm install <whatever-i-need>" muscle memory.

I agree with you, current models can't work totally outside their training set. An example of AI that trained with environment and feedback/outcome learning is AlphaZero, and it totally beat us at our own game. Even so, DeepMind seems not to care to pay the costs of further development, so we see LLMs need to make themselves useful to people to survive. It's a "pay your costs or stop executing" situation.
Anyone used Reducto for parsing? How good is their embedding-aware chunking?
by Bahushruth | 2025-10-25 13:02:54+00:00
Curious if anyone here has used Reducto for document parsing or retrieval pipelines.

They seem to focus on generating LLM-ready chunks using a mix of vision-language models and something they call “embedding-optimized” or intelligent chunking. The idea is that it preserves document layout and meaning (tables, figures, etc.) before generating embeddings for RAG or vector search systems.

I’m mostly wondering how this works in practice

- Does their “embedding-aware” chunking noticeably improve retrieval or reduce hallucinations?

- Did you still need to run additional preprocessing or custom chunking on top of it?

Would appreciate hearing from anyone who’s tried it in production or at scale.

I don’t believe you. My local Best Buy has 134 different laptop models in stock in the store.

Have you ever heard of Amazon prime? You really think they don’t have a suitable laptop they can deliver to you overnight or maybe even the same day?

And anyway, this is really only an argument for “whatever is most popular,” not “what is the best machine.” If some other brand besides Apple was the most popular laptop in the world that other brand would get this same treatment by you even if the computer sucked (which MacBook Pro did between 2016 and 2020)

Essentially you’re saying that Budweiser is the best beer because it’s the most available. If I run out of beer I can get it anywhere.

You misunderstand, I didn't say hypfer should or shouldn't do something. I said I don't want to use his project, as is my right, because I don't like being banned from talking to anyone who might have the same problem as me if I say something hypfer doesn't like.

Even so, I'd be happy to run a community for any other project, but I don't really like hypfer's behavior and don't want to help him out.

> Isn't this just how the DOM works? Data flows down through attributes and properties; events bubble up?

That's right, but this communication pattern causes serious complexity. Imagine trying to find out what triggered a state change. You would have to listen to every event source to find out. With Flux, all state changes were mediated by the reducer in the store. It made things a lot simpler.

>why are we arbitrarily trusting what the manager and engineer says “at face value” but not OP?

Trust does not matter. The manager might be totally wrong and the guy is getting worse and worse. This does not matter for my argument, which is that the manager puts his opinions above the one of the team lead. And he sees the team lead as part of the problem. Do you think there is an alternative explanation besides the manager not believing in the leadership qualities of OP?

I am also not trusting what the problem guy says, except that OP calls him a competent jerk, which tells me that OP does not disagree that the problem guy is a capable engineer.

>Where on earth is it even remotely implied that OP lets the engineers do what they want?

I wrote it below. If you are the leader of 10 people, 9 of whom trust you and 1 constantly disagrees with you, you can still push through any decisions, because the 9 people will stand up for you and force the one guy to accept whatever you decide.

Imagine having to go to your manager because one guy in your team of 10 does not want to do a post mortem. There have to be 9 other guys who do not care at all about your decisions, else they would have immediately stood up for you, for something as reasonable as a post mortem.

So why do you love working for a leader, but do not care at all when the leader gets criticised for something extremely reasonable. They do not like him because of his leadership abilities. Maybe they like him because he is a nice person or because his lack of leadership gets them something they want.

Don't give up on older stuff just because deep learning went in a different direction. It's a perfect time to recombine the new with the old. I started DuckDuckGoing and found combinations of ("deep learning" or "neural networks") with ("gaussian," "clustering," "support vector machines," "markov," "probabilistic graphical models").

I haven't actually read these to see if they achieved anything. I'm just sharing the results from a quick search in your sub-field in case it helps you PGM folks.

The trust levels in Police is much lower in larger countries. In Germany it’s %50 and %35. NL is not the rule, it’s the exception.

But sure, hating the police is an exaggeration. Still, I think it’s obvious that its for illustrative purposes and not a declaration. Just like everybody never means every single person no exceptions when talking about general situations. It’s like when you say “everyone knows that the flat earth theory is BS”. Yes it’s not everybody and your mileage may vary depending on the location.

You forgot to quote the part where I said he can refuse in a normal and respectable way.

If you make a garden and then declare it a public garden then yes. If you want people to not step on your flowers you can tell them in a normal way. No need to shout around, belittle them, and ban them from your garden for a year....

He could have just kept his Project private if he doesn't want people to interact. Simple as that.

Thanks. I'm not going to be very specific here because I'm too lazy to dig into that giant type, but if they want that method implementation to work without type assertions then the `add` method would need to be typed as an assertion function[1] so the type system can understand that it narrows its argument[2].

Here's an example: https://tsplay.dev/w8y9PN

[1]: https://www.typescriptlang.org/docs/handbook/release-notes/t...

[2]: Doing this isn't safe anyway because it mutates an object in a type-relevant way while there may other variables referring to it (the safe thing to do is return a new `Elysia` instance from `get`), but that's beside the point.

The issue for me with batteries is that in the summer I can produce in a day much more than I can use, and in winter I consume a lot and barely produce anything. This is where net metering steps in- I can ‘store’ all of my excess summer consumption in the grid in summer and get credit for it in winter.

A cheaper smaller system right sized for summer consumption with a battery would have my second best option, but for me never showed any potential payback due to the fixed costs of installation and the extra battery costs.

I've run a self-hosted Nextcloud instance for many years and Docker is by far the easiest. I started off with a native installation and that can be a pain when upgrading the OS (Ubuntu in my case). I tried the snap version when that became available and was impressed by how easy it was, though administering it required a bit of learning as the file locations where all different.

Running it in Docker made it so much easier to administer (maybe add in the missing db indexes if there's a major version change).

If you want, I can paste my docker-compose.yml for reference as it's relatively complex.

That x86 machine code link reminded me of an LLM project I did just last week - https://tools.simonwillison.net/sloccount

I decided to see if I could get an old Perl and C codebase running via WebAasembly in the browser having Claude brute-force figuring out how to compile the various components to WASM. Details here: https://simonwillison.net/2025/Oct/22/sloccount-in-webassemb...

Here are notes it wrote for me on the compilation process it figured out: https://github.com/simonw/tools/blob/473e89edfebc27781b43443...

I'm not saying it could have created your exact example (I doubt that it could) but you may be under-estimating how promising it's getting for problems of that shape.

People who are older or with limited mobility find it far easier to get see multiple destinations without having to unpack/pack, navigate difficult airports, etc. I have been on a few, and while I’m not the biggest fan, they’re not terrible if you are traveling with folks who have mobility issues. I would not go on a cruise after COVID, though.

They’re also far less expensive than many other vacations, especially if you have kids and are considering Disney stuff.

Still a human Petri dish.

You do know that BPA-free just means they use BPS or some other bisphenol plasticizer, right? Right? Because all of the research was focused on BPA and nobody tested BPS even though they're quite similar chemically.

You just can't polymerize plastics without a plasticizer. It's just not allowed by chemistry. No free lunch.

If you want something that's not going to leach huge amounts of plasticizers onto your fingers, use an inkjet or a laser toner printer or a laser marking machine.

They don't really make those for receipts, though, because fingers tend to be wet and powdered toner is expensive.

> The consensus has been that this is an acceptable risk, particularly since COVID itself is associated with an increased risk of myocarditis.

This made more sense to me when people still believed that the shots meant getting covid was very unlikely. It's easy to find people who got lots of shots, it's hard to find people who didn't get covid.

It always seemed implied that p(shot cardio issues) < p(covid cardio issues), and nobody ever talks about p(shot cardio issues) + p(covid cardio issues).

Did anybody rigorously demonstrate that a vaccinated covid case doesn't have these risks?
by crazygringo | 2025-10-25 13:08:10+00:00
Why do people comment on HN? Different strokes for different folks.

But basically you get to see a bunch of destinations while all your travel is organized for you, you never have to switch rooms and constantly pack/unpack, and the actual travel part is infinitely more comfortable.

A room and sundeck and pool beats a plane seat or train seat any day.

I'm not into cruises myself, but the appeal seems pretty understandable in terms of convenience.

No exams, only individual growth meant there's no guarantee the kid is learning at a good pace.

that's not true. it is possible to notice if a kid is learning at a good pace without exams. that is part of what the montessori method is about.

it sounds like this school just picked the things they liked but did not understand the point. the core of the montessori method is intensive observation, to understand what the children need and how they can thrive. it looks like this didn't happen in your daugthers school.

> Do people actually ignore a comment explaining a problem with the code as written just because it wasn't a blocking review ?

Approval is approval. If you complete your review and don't block, you have concretely indicated to the author that in fact nothing is wrong with the diff and it is ok to be merged as is no matter what else you said. Many authors won't even look at comments if their change is approved.

Web Components are anything but simple, are cumbersome and inconvenient, and have even more footguns than the already footgun-y React.

Even if you only mean "custom elements" instead of "Web Components" (which "custom elements" are part of) they are still absurdly complex for what they do: how is it simple that instead of just having properties you have attributes AND properties, which are completely different things even though you'd expect them to serve the same purpose, and now you're in charge of syncing them!?

I'm trying to get away from the imperative DOM, not create even more quirks and footguns for my consumers!

They're not even meant to replace React. Web Components don't do templating. You can perfectly build Web Components with React since a Web Component is not concerned with rendering at all. If anything they are a replacement for jQuery-based "component"-wrappers (which were already replaced long ago... by React completely changing the frontend paradigm).

And they are client-side only. By design. They don't and will never work with JS disabled. Rendering a custom tag server-side just sends that custom tag over the wire... and there you can only send attributes (which are string-only) so good luck with complex stuff like a huge datatable.

You can tell they were designed by committee because they solve problems from 15 years ago in a worse way than the SotA.

Components are themselves a form of added complexity. The idea is to deliver a composed and self contained code island. To accomplish this you have a big ball of markup, presentation, event handling, business logic description, and then security and accessibility logic to compensate for the prior mentioned abstractions. What you see in your editor may not look like much, but just under the hood is a colossal mountain of foolishness.

Why do people prefer this? It doesn't increase speed of maintenance. Its preferred because its composable to a predefined architecture scheme the developer is comfortable with. That's it. Its just about comfort, but the complexity is through the roof.

Simple isn't free.

I frequently use one-time alarms for early morning travel a few days away. What makes them great is that the alarms in general are much more robust in their requirements to turn them off; I can accidentally dismiss a calendar alert, but I have a much harder time accidentally deactivating the clock alarm in a sleep induced stupor at odd hours.

More importantly, alarms don't get silenced by my nightly do not disturb schedule.

If I understand you correctly, your hypothesis is that a COVID-19 vaccination, while it doesn't immediately kill someone, can cause conditions which lead to increased mortality.

With people still being re-infected by COVID, despite the pandemic being "over," could a COVID infection, itself, cause conditions which lead to increased mortality (for people who don't die from acute infection)?

I'm not proposing this as an either/or; I'm just saying that the vaccine wasn't the only change since 2020 :)

I was responsible for maintaining a large backbone app over the course of 10 years.

The main thing to know about Backbone is it’s not intended to be a fully fledged framework like React.

It’s more like jQuery in the sense that it has utility, but in order to use it in a way that is easy to maintain over time, you need build your own layer of abstraction on top of Backbone to make things work the way you want.

React has a lot more of that built-in, and the downside is React is more opinionated with a “right” way to do things, while Backbone leaves a lot up for the developer to decide how to do. I guess this could be a benefit of react depending on how you look at it, or whether you want an opinionated framework.

All that said, I will always love Backbone for being the only open source framework that has source code that is actually possible to fully read and fully understand in a few hours in an afternoon.

The source code is surprisingly simple and easy to understand. There’s very little magic going on behind the scenes.

Well, there are manganese-based contrast agents under development. Maybe we should give those a little more funding.

Like Gd, Mn is toxic, but unlike Gd, Mn is naturally present in the body (and also in pineapples) which means that long-term accumulation is less likely. The main difficulty is the lack of strong enough complexing agents because of the tendency for zinc (naturally present at relatively high concentrations in the body) to steal the ligand from Mn, a problem currently being studied:

> I was an addict. I know what I am talking about.

You know what your lived experience was, that doesn't make you an expert on how addiction works on a physiological level.

> Ultimately you have to want to quit. That is a decision made by me. That requires my own agency.

You're just repeating truisms. Yes of course people have to want to quit, but out of the people who want to quit, most are unable to follow through. They relapse despite fighting like hell inside their own minds.

> From your jab earlier about my apparent "conservationism"

You mean the thing that didn't even cross my mind until you brought it up, unprompted, after repeating the exact ideas I would expect from the group you claimed that you weren't apart of? And then in the same breath accusing me of not understanding anything about addiction?

That was slightly amusing, yes. I'm sorry you found that offensive.

P.S. I don't know why you accept that you were in full control of your addiction, nor do I care because I'm not trying to take away from your own personal experience. If that makes it easier for you to move forward, I'm genuinely happy for you, but you don't get to use it to lift yourself up and put others down the way you've been doing.

The problem of algorithmic feeds gets a modest amount of attention, but I still think its not nearly enough. Addicting feeds are evil. If we ever manage to make it beyond them, we'll reflect on them with the same regret as slavery.

A quote from an author I like, Matthew Crawford: "Attention is the thing that is most one’s own: in the normal course of things, we choose what to pay attention to, and in a very real sense this determines what is real for us; what is actually present to our consciousness. Appropriations of our attention are then an especially intimate matter."

I can't really envision a solution, frankly. On a personal level, I have tried dozens of strategies to use my phone less, including deleting many of my social media accounts, and regrettably, its still an issue. My best guess is legislation that bans machine-learning algorithms on newsfeeds. But there are billions of dollars and a dysfunctional government (speaking U.S. here) motivated against that outcome.

There is, I think, a sort of innocent arrogance that comes with people who boldly claim that renowned, well-adopted frameworks or technologies are straight up bad or a non-improvement over yesterday’s tech.

That’s not to say popularity guarantees quality, that progress is always positive, or that there’s not plenty to criticise. But I do think authors of articles like this sometimes get a big hit from being subversive by playing into retro-idealist tropes. The engineering equivalent of paleo influencers.

Such proposals would suggest a huge global collective of the world’s most talented engineers have been conned into fundamentally bad tech, which is a little amusing.

It's contrived and breaks down pretty easily, but why isnt it more like this:

- both wearing seatbelts and getting in an accident have a significant chance of causing x

- you are almost definitely going to get in an accident

- are your chances of x greater or lesser given car accident while wearing seatbelt?

I think your framing is correct (though it'd be better to just say were better off in general), but I haven't seen anyone give a convincing answer to that question in favor of the shots.
