More like the Egg of Columbus or the Red Queen.

You need to run as hard as you can just to stay where you are, and once you've got the answer it's very much easier to reproduce the result.

This is of course also what annoys a certain fraction of commenters in every discussion about LLMs (and in art, diffusion models): they're overwhelmingly learning from the examples made by others, not investigating things for themselves.

While many scientists will have had an example like Katie Mack's viral tweet* with someone who doesn't know what "research" even is in the first place and also mistakes "first thing I read" for such research, the fact many humans also do this doesn't make the point wrong when it's about AI.

Actually, it was the Shapeoko 1 which introduces the idea of belts (MXL), then switching to Gates GT2 belts with the SO2 (ob. discl., I got a free machine for doing the instructions, see Github). Since it was opensource, the X-Carve was forked from the SO2, though the X-Carve Pro was a completely new design.

Note that belts were continued through the Shapeoko 3 (I got a machine as a "thank you"), though the Z-axis got a leadscrew in the Z-Plus upgrade, then the Pro (since, I got a job with the company and got an XXL as part of my employment), then the 4 (the original Pro is referred to as a 4 Pro sometimes), and it is only with the 5 pro that ball screws were switched to for all axes (and I now have a 5 Pro).

For an example of what a belt-drive CNC can do see:

You made a specific claim about human behaviour. Either defend it with evidence or admit you were speculating. The philosophy of science lecture doesn't change that.

You can't say "HN's resistance stems from psychological discomfort" (empirical claim) and then retreat to "there are multiple epistemologies" (relativist defence) when challenged. You're held to the epistemic standards your claim invokes.

If you'd made a claim like "Critical theory suggests that HN's resistance stems from psychological discomfort" I'd have a lot less to say. It still suffers from the same evidence issues but at least you're being clear it isn't a scientific claim - so you wouldn't be getting pressed for scientific evidence.

> There are more epistemologies in the world than just the scientific.

Yes, different epistemologies have different domains, boundaries, and use cases (sometimes they overlap too). This is why scientific analysis is useless for literature - and why literary analysis is useless for science.

This is just like how you can't do brain surgery with a jackhammer, and you can't dig concrete with a scalpel. Statistical analysis on poetry is nonsensical, and no one would accept a literary analysis on quantum mechanics as physics.

Different tools are fit for different purposes.

> the tone policing and boundary policing here aren’t very scientific

I'm not tone policing, I'm holding you to the scientific standard after you made a scientific claim. Calling standards enforcement "tone policing" is just another way to avoid accountability.

"Boundary policing" in science isn't some arbitrary gatekeeping - it's essential intellectual hygiene. Good science is acutely aware of:

- What methods can and cannot establish

- The scope and limits of findings

- When they're stepping outside their domain of expertise

- The difference between correlation and causation

- What constitutes sufficient evidence for different types of claims

This is why we have concepts like:

- Statistical power and confidence intervals

- Replication requirements

- Peer review processes

- Methodological limitations sections in papers

This boundary distinction is the entire foundation of reliable knowledge production.

> you've set up a heads I win, tails you lose set of rules when it comes to epistemic choice.

You did this to yourself when you made a scientific claim without scientific evidence. It's not my fault when I point out you built your argument on epistemic quicksand.

You want to make truth claims with scientific authority while escaping scientific accountability.

> I’m sure you’re aware of this dynamic playing out in this very discussion.

Yes it's meta, your original claim still requires evidence though.

Bureaucracy is always corrupt, incompetent and self-serving to varying degrees. There is no way around it, it's a necessary evil for communication and organisation. At least governments in democracies have some form of oversight on them, there is less oversight in corporations or dictatorships.

Maybe an AI dictatorship would rid us of bureaucracy, but we'd both end up in a paperclip sweatshop.

I just pull the plastic off and microwave it for a half hour in the combined convection oven/microwave mode till its crispy and then eat it. Pretty sure no botulinum can grow that way. In general I feel that "microwave/bake till slightly crispy" is a underrated food preparation method and I feel very Diogenes-esque for having discovered it.

There's an attempt to kinda have these things documented for AIs, called llms.txt, which are generally hosted on the web.

In theory, an AI should be able to fetch the llms.txt for every library and have an actual authoritative source of documentation for the given library.

This doesn't work that great right now, because not everyone is on board, but if we had llms.txt actually embedded in software libraries...it could be a game changer.

I noticed Claude Code semi regularly will start parsing actual library code in node_modules when it gets stuck. It will start by inventing methods it thinks should exist, then the typescript check step fails, and it searches the web for docs, if that fails it will actually go into the type definition for the library in node_modules and start looking in there. If we had node_modules/<package_name>/llms.txt (or the equivalent for other package managers in other languages) as a standard it could be pretty powerful I think. It could also be handled at the registry level, but I kind of like the idea of it being shipped (and thus easily versioned) in the library itself.

>people vastly overestimate their efficacy and efficiency

If anything, solar has demonstrated over the past 2 decades that it is a lot more effective and economical than even the most bullish of predictions that have been made about it. (Seriously, look at projections for solar deployment and generation vs what actually happened, it's kind of crazy how much it was underestimated)

> But someone in a remote part of England will get the same advice as someone in central London,

The current system might not have perfect geographic granularity but that doesn't mean it isn't preferable to one that gives advice from half the world away.

> Human biology is the same, diseases are the same, and the difference in available treatments is not usually all that different

Accepted medical definitions differ, accepted treatments differ, financial considerations, wait times and general expectations of service vary wildly.

> I use it for years to achieve HA for personal mail servers and will now have to look for alternatives

Yeah, Dovecot seem to be going hardline commercial. Basically the open-source version will be maintained as a single server solution. Looks like if you want supported HA etc. you'll have to pay the big bucks.

There is a video up on YouTube[1] where their Sales Director is speaking at a conference and he said (rough transcript):

"there will be an open source version, but that open source version will be maintained for single server use only. we are actually taking out anything any actually kinda' involves multiple servers, dsync replication and err some other stuff. so dovecot will be a fully-featured single node server"

Have you looked at Stalwart[2] as an alternative ?

I lived in a city with this once, and beyond the novelty factor of the first few weeks after I found the app, I stopped using it. Looking up routes on your daily commute is just too much friction. The display at the station/stop is by far the best indicator, you can see at a glance how long you have to wait when you get to the stop.

So, can i be the voice of reason here? The Panopticon is unavoidable! Everyone who has a spark of self-preservation in himself, knows it already. Technology has given the individual insane powers to take down state-level actors (drones in shipping lanes) and soon the whole planet(mirror life etc.). We can no longer afford privacy, as sad as this is.

Privacy was a luxury we had, while we could bribe the better angels of our nature with the surplus of the past and while technology was something, that did not scale.

Now a terrorist could take a army of tanks while besieging a city. All the other justifications for a Panopticon are flimsy, but the fact that technology - our savior from savagery, has turned around and bit the hand it was supposed to feed, justifies the thing.

The majority of the linked articles is waaayyyyy too long for what they have to say, and they reveal the subject only many paragraphs in.

From reading one or a few short comments I at least know what the linked article is about, which the original headline often does not reveal (no fault of those authors, their blogs are often specialized and anyone finding the article there has much more context compared to finding the same headline here on a general aggregation site).

Ha! I have the same problem. Paper is cheap but there is a pressure to make the whole notebook a piece of art.

In my case, I find revisions useful as a sort of deliberate practice. I eventually find the right way to do something, after many attempts. Polishing turds is a great way to see where I make mistakes and how to fix them.
Show HN: Rejoy Health: AI Search Engine for Doctors, Used by 50k Physicians
by rituraj_rhealth | 2025-07-24 10:40:27+00:00
Hi HN,

We’re the team behind Rejoy Health, an AI search engine built specifically for doctors. We launched it to solve a frustrating but critical problem: Clinicians spend too much time searching through dense PDFs, outdated databases, and fragmented resources to find reliable answers to clinical questions, especially at the point of care.

With a new medical paper published every ~30 seconds, it’s impossible to keep up. Rejoy lets doctors ask questions in plain language (e.g. “How do I manage atrial fibrillation in elderly patients?”) and get trusted, evidence-based answers with linked sources in seconds.

Think of it as a conversational interface(ChatGPT for doctors)to the medical literature, with citation transparency built in.

We're not trying to replace doctors or provide medical advice to patients, just reduce cognitive load and help them move faster with information they can trust.

Some quick points:

* Trained and tuned specifically on high quality, peer reviewed medical content

* Used by 50,000+ physicians so far

* Enterprise deployments support on-prem or VPC, for health systems that need full control

We’re focused heavily on verifiability (everything is sourced) and safety (reliable fallback answers > hallucinated ones)

Would love your feedback on everything—from the retrieval stack to deployment, use cases, and UX. Happy to answer questions about how we built it or how clinicians are actually using it day to day.

https://www.rejoyhealth.com

Thanks!

There are two aspect I don't like:

1. It is inconsistent, especially during winter and when fully charged.

2. Crossings with shrubbery/objects that hides approaching pedestrians/cars/bikes and it is rare that there is anyone actually crossing. I encounter these several times per day.

My preferred way of approaching #2 is to reduce speed well ahead, start gliding and put my foot on the break pedal to be ready for a complete halt in the rare case (once in a 500 maybe) that I need to give way to someone. In the Tesla I must reduce speed to almost standstill and creep slooooowly, since it would take half a second to move the right foot to the break.

I understand it sounds like an extreme corner case, but for me it is all the time every day. Central Scandinavia.

Sure, if something is super critical then you should solve the problem as fast as possible. I'm not debating that. But there's probably a middle ground there somewhere for less critical issues. I suspect the process of generating and falsifying hypotheses quickly is the skill, and I don't know if you can effectively train that skill after an incident, when you've already seen the resolution.

Chess is maybe not a great analogy, because there are rarely objectively correct answers, only hard trade-offs. For that reason there's still a lot of value in reviewing a finished game.

This reminds me of when a student pub hosted a wedding party. As we got to the dance floor there were drinks on offer. I grabbed a Cuba Libre and essentially went "oh, that's the roughest on I've had, must be cheap cola on truly awful booze". Kept on sipping. Someone else complained. Then another one. We go back to investigate. Bartender has a taste. Grimacing.

Like bad and maybe salty?

Takes a minute before they track it down. They'd mixed up the salted ice cubes they used to keep champagne cold with the ones they use for drinks.

That one was rough. I had politely worked through my drink before we launched the investigation. Good party though and I did get a new drink which tasted fine.

I'm sure a tiny pinch can do wonders. Salted cubes, not recommended.

It didn't get clearer much: so what am I supposed to do to achieve that? If I query AI and it gives me outdated instructions how is your server supposed to help here? I suppose that I am supposed to somehow direct that AI's pipeline to use MCP protocol to make as a next step and query a locally running instance of the server of yours to improve the final answer..? The solution sounds quite ad-hoc: so instead of fixing the problem where it is (in AI's knowledge base), you suggest to apply corrections to it's results by making it query a server each user supposed to run locally? Sounds as a wrong approach to me, I honestly doubt many people would bother working with AI that way, especially given that AI is a paid service.

What I think would be great is either you hosting a central server permanently available to public and somehow convincing major AI service providers to query your servers for solving that narrow scope of tasks, or rather do something similar for open source models available on Hugging Face or something.

And then the part where you have to create an account to read past the SEO filler :(

It's so sad, cause it drags down good pages. I recently did a lot of research for camping and outdoor gear, and of course I started the journey from Google. But a few sites kept popping up, I really liked their reviews and the quality of the items I got based on that, so I started just going directly to them for comparisons and reviews. This is how it's supposed to work, IMHO.

no it's not at all

calling humans aliens is NEVER normal, this has always been racist discriminatory, de-humizing language.

and yes ICE has used such languages for a while, and they also have done things for a while which by international law (mainly the parts conveniently not recognized by the US) are crimes, some very heavy crimes, too (like when they split very young children of illegal immigrants from their parents and sold them to orphanages)

Stolen: There was some research a year or so ago that showed if you have access to the probability distribution for the next token, you can efficiently steal some layers of the model. When this work was done, OpenAI switched off direct access to those probabilities.

Distilled: Two years ago, one of the AI podcasts I was listening to (probably TWIML&AI) had someone use a big model to create a small high-quality training set for another model (as I understand it, this is what Microsoft's Phi series does, but that wasn't the example in whichever podcast I'm thinking of).

And remember, OpenAI's price for a million tokens is a rounding error for most businesses. Last year's reported revenue of USD 3.7 billion* suggests their customers collectively paid them for order-of a quadrillion tokens in and out, so even getting a trillion tokens from them without them noticing what you're up to (so long as you paid) is very plausible.

I worked a year or so at an Elixir shop, and this mirrors my experience. I had to navigate to call sites to understand what I was being passed and type hints were not sufficient. Dynamic typing fails larger orgs/teams/codebases.

Fun to develop and solo administer. Small teams with a well known codebase can do amazing things. I work at orgs with multiple teams and new hires who don't know the codebase yet.

For me, the sweet spot is Go.

The real question: Are the recent recommendations better than previously? Example: If the recommendation engine (presumably driven by some kind of AI/LLM at this point) better understands the content of videos, it can make better recommendations. If anything, it seems logical that smaller channels would begin to appear on your YouTube feed, as long as the content is highly quality and matches your interests.

We're talking about hundreds if not thousands of complaints here for Pornhub, that went ignored for years.

We're talking about highest level politicians in the EU raising serious stink first, then threatening regulation and only then following through with it in Meta's case.

That's far, far beyond "some instances".

I wouldn't recommend doing it from a cronjob, there are sometimes things that require sudo to update, breaking changes and important notes from Brew maintainers in the output. It's really important to inspect the output in order to see everything Brew doesn't consider normal.

Lately I'm running this like once every 2-3 weeks and it's still surprisingly nice to use. The problems only really manifest when you never run this "maintenance" snippet and only use the `brew install`, which will attempt to do the housekeeping stuff when you want/expect it the least.

>If all the characters in games were people that you couldn't relate to and that you don't feel represented by, you wouldn't like that, no?

Games are a visual medium, like movies, which is why games with attractive characters are generally more popular, and just to be clear simple graphics like in Schedule I are not unattractive or ugly.

More importantly how a character looks has nothing to do with how relatable a character actually is - it an absurd premise. What you are basically saying is that people won't enjoy playing Stray because they are not cats, which obviously isn't true and doesn't make sense. It's the same in movies, when watching Wall-E people don't go "well I'm not a trash compactor so I can't relate at all".

>Embracing that people are different is something that is good for everyone.

And I would agree except that in reality it isn't include non-attractive looking characters along side attractive ones, it's always to exclude what you call "standard beauty standard".

As an example of this if would really is about just giving options to player then why is the breast slider in Dragonage Veilguard limited so that players can create only characters with small breasts? Where did the "representation", "inclusivity", "player choice" go to with regards to large breasts?

Yes, I haven't been to Satan's Whiskers but it wouldn't surprise me at all if it was as expensive as Bar Americain (or moreso).

Bar Americain is probably my favourite cocktail bar in central London, though I'm not much of a cocktail drinker so that's not saying much. The Connaught is good for a special occasion (very opulent, also very expensive).

Which is why I'm surprised electric cars with range extenders aren't a bigger thing:

* https://en.wikipedia.org/wiki/Range_extender

Have the powertrain be all-electric, and have a battery pack, but for those with range anxiety have a small generator as an option that would go in the frunk (front truck). A (proverbial) small Honda EU2200i would be less maintenance than a traditional engine.

It's a great list. I believe Uber has improved on both of those items although could still do better (see e.g. [0]).

The issue with the second list is that it takes a long time to encourage that sort of social progress. It's extremely difficult to undo years of conditioning, so I think we have to wait it out until that generation ages out. In the meantime providing safety options for women in limited high-risk scenarios feels very jutifiable. And we continually reassess what those scenarios are so that we're allocating those measures in an efficient and moderated way.
