The irony here is using fitness as an example of knowable things.

Fitness guidelines is very much not a settled science, and is highly variable per individual beyond the very basics (to lose weight eat fewer calories than you burn, to build muscle you should lift heavy things).

For every study saying that 8-12 reps x3 is the optimal muscle growth strategy there is another saying that 20x2 is better, and a third saying that 5x5 is better. If you want to know how much protein you should eat to gain muscle mass, good luck; most studies have settled on 1.6g/kg per day as the maximum amount that will have an effect, but you can find many reputable fitness sources suggesting double that.

You can memorize "facts", but they will change as the state of the art changes... or is Pluto still a planet?

The ability to parse information and sources, as well as knowing the limits of your knowledge is far more important than memorizing things.

Watchpoints (breakpoint that triggers when a given memory address is read/written/both) are the other huge UX advantage over prints. They're not quite as universal: you can almost always "print" by blinking an LED even if you don't have the luxury of a UART or other console, and some extremely low-end MCUs don't have any sort of watchpoints, but almost everything else does. A watchpoint that logs which source line wrote to the address in question & continues execution automatically is one of the easiest ways to debug memory corruption.

Urban is usually associated with panhandling, trash, public urination and crime.

> "Galicia is mainly and historically ruled by the right-wing Popular Party"... (Galician Nationalist Bloc)

So they likely have much stricter standards of what constitutes acceptable urban behavior...

... than, say, New York, where very recently a person with 30-year criminal history has allegedly killed a couple...

... or in Charlotte, where an Ukrainian refugee was fatally stabbed in the light rail.

I was alive at that time and I loved the Redwall books, Enders Game, LOTR before the movies, and some Heinlein. Never read Harry Potter, which came out when I was in middle school. And I was a girl.

Characterizing girls as only liking Harry Potter and Orlando Bloom is like saying boys only liked WWF and Jackass. It's a mindless stereotype.

(Mentioning beforehand that we're still very early when it comes to the exact behavior of each language model)

So far, I've observed that for Claude and Gemini, which are what we've been testing most with, the Language model has been pretty good at recognizing its a faulty initial interpretation when it queries more information from the system.

Running out of tokens is a more significant issue. We saw it a lot when we queried imaged topics, which led us to try writing better image interpreters within the MCP server itself (credit to my collaborators at the Hanyang university in Korea) to defend the context window. Free tiers of the language models also run out of tokens quite quickly.

PS - Thank you for the questions, I'm enjoying talking about this here on HN with people who look at it critically and challenge us!

I had a case just recently where we needed to enforce a no-overlap constraint too complicated to express in an index (recurring time ranges).

Any time you have to check constraints manually, you can't just do it before the write, or after the write, because two REPEATABLE READ write transactions will not see each other's INSERT.

You need something like a lock, a two-phase commit, or SERIALIZABLE isolation for writes. Advisory locks have sharp edges, and 2PC is not so simple either, there is a lot that can go wrong.

In the case of SERIALIZABLE you do need to retry in case of conflict, but usually the serialization anomalies can be limited to a reasonably fine level. And an explicit retry feels safer than risking a livelock situation when there is contention.

You could read the article? It has to do with regulatory changes, rising fraud, and a string of hurricanes which drove prices up in FL and temporarily reduced competition. Since then rates now seem to be growing behind the rest of the nation as more small insurers enter the FL market and compete.

What is important to remember though is weather event =/= climate change. We expect a certain amount of randomness in hurricanes and natural disasters, and saying a year with more hurricanes is due to climate change is the same as saying a cold winter disproves global warming/climate change.

No it isn't clear that Americans love cars. Some Americans love cars or course, but for many they are something they think they must have but they don't really care about the car. People want to get places, people need to get food, and so one - a car enables all of those things, but they are a tool to get things done, not the point. They do not think there is any other tool that will work, but that doesn't mean they care about that tool. They are against transit because they think it is a waste of money since even after spending that money it still wouldn't work (this may or may not be true) and so it isn't worth it.

Sorry, kids lack the foundational ability to remember, reason, imagine because their phones cauterize their basic intelligence foundations in sharp wave ripples: navigation, adventurous short-cuts, vicarious trial and error, these are the basis for memory consolidation. And we build this developmentally until we are 16 or so. Once we offload this dev to phones, we are essentially unintelligent buffoon, lacking the basis for knowledge. The kids are DOA.

Progress is hard to keep track of in this fast paced environment, but aren't there already models that can add external tools and simply offload parts of he reasoning there? Maybe over MCP or some other mechanism, so it can offload e.g. calculations, or test code in a sandbox, or even write code to answer part of a question, execute the code somewhere, and take the results into the rest of the inference process as context?

Or is there a more subtle issue which prevents or makes this hard?

Is there something fundamentally impossible about having a model detecting the amount of Rs in 'strawberry' to be a string search operation and in some sandbox execute something like:

% echo "strawberry" | tr -dc "r" | wc -c

It seems agents do this already, but regular GPT style environments seem to lack it?

Email is not relevant to a good encryption scheme. You could sign an email, an image you post on Insta, a chat message, anything really.

Thing is, where are the user's credentials stored. In a goverment's computer probably. Greece is taking some steps towards this [1].

A Greek citizen to obtain a digital signature, he has to go to a bank, the bank verifies him, he pays a fee and then the government can accept his digital signature. My guess is that the dictatorship banks established with the Covid excuse might start to bear some fruits finally.

But, people on the internet might want something more advanced, more secure than some COBOL computers storing their identity. Then we save digital certificates and digital identities on the blockchain, making essentially the blockchain the heart of the internet.

When a person from a company sends a message to a client, he can sign the message with his own identity and the identity of the company. Problem solved. No one get's confused when the cryptographic signatures are not verified. The message is invalid and it is redirected to the spam folder.

After moving my kids out of a bad elementary school and into a fantastic district with a highly ranked school, the differences are obvious. The good school has smarter kids with better parents. The bad school had dull kids with bad parents.

The kids at the new school do their homework, read, play outside. The kids at the old school skipped homework, played call of duty, and could hardly read.

The new school has fun exercises like the "word of the week" -- and they swear they will rarely assign homework. The old school had mandated trips to the library so kids could take home books and ignore them, alongside a minimum of 1hr of homework per night.

In the bad school, a class of 24 had 11 kids who would not behave themselves, ever (one of the kids would often pick up his chair and hit other students and his aide). In the good school, a class of 24 has 1 kid with limited behavioral issues.

Anyways, the people make the place -- and that includes kids.

This kinda stuff brings languages like C# and Java closer to Rust in performance, thinking like the "borrow checker" it understands the scope of some objects and puts them on the stack and avoids garbage collection and allocation overhead.

It keeps the unsung benefit of garbage collection for "programming in the large" in which memory allocation is treated as a global concern independent of everything else instead of a global concern that has to be managed locally in every line of code.

Rust's strategy is problematic for code reuse just as C/C++'s strategy is problematic. Without garbage collection a library has to know how it fits into the memory allocation strategies of the application as a whole. In general a library doesn't know if the application still needs a buffer and the application doesn't know if the library needs it, but... the garbage collector does.

Sure you can "RC all the things" but then you might as well have a garbage collector.

In the Java world we are still waiting for

> You are incorrect

How so?

> Laptop batteries are overwhelmingly NMC or similar chemistries

Yep, I was not debating that.

I was not trying to imply any particular percentage of laptop batteries are LiFePo4, just that they have existed at all in that field for years now.

There are several laptop manufacturers that are regularly using lifepo4 now.

> LiFePo4 is extremely safe

I would say it is safer than li-ion but still not near as safe as an all-solid-state battery.

The wall of text here, as well as the wall of text on the submission, keeps using the word Tauri but not saying what this is. Wikipedia says Tauri are Crimean settlers. Think I found it now: https://tauri.app

That page says that "By using the OS’s native web renderer, the size of a Tauri app can be little as 600KB." sounds like an alternative for Electron basically
Show HN: SuppSnitch – Scan supplement bottles to analyze ingredients and risks
by krispycreame | 2025-09-10 16:15:29+00:00
I built an iOS app that scans supplement bottles (back and front photo) and uses AI to break down ingredients, flag possible risks and expose certifications (like claims to be vegan but actually not).

Would love feedback on the app.

You make it sound like you’re just shifting the problem elsewhere, when this isn’t the case.

It’s not wholly subjective. Some of the processes you can use to understand your data are mathematically proven. Many others are well-tested.

In any case the idea is to try to minimise your biases and check whether your assumptions are valid so that you can make better, more reliable, more informed decisions. It doesn’t have to be a perfect system to be better.

You might not want to, of course.

1. it probably did for quite a few recipients, but that's never going to be 100% 2. not helped by the current practices of the industry in general, many domains in use, hard sometimes to know if it's legit or not (some actors are worse in this regard than others)

Either way, someone somewhere won't pay enough attention because they're tired, or stressed out, or they are just going through 100 emails, etc.

I am sympathetic to memory-focused tools like Anki and Zettelkasten (haven't used the latter myself, though) but I think this post is a bit oversimplified.

I think there are at least two models of work that require knowledge:

1. Work when you need to be able to refer to everything instantly. I don't know if this is actually necessary for most scenarios other than live debates, or some form of hyper-productivity in which you need to have extremely high-quality results near-instantaneously.

(HN comments are, amusingly, also an example – comments that are in-depth but come days later aren't relevant. So if you want to make a comment that references a wide variety of knowledge, you'll probably need to already know it, in toto.)

2. Work when you need to "know a small piece of what you don't remember as a whole", or in other terms, know the map, but not necessarily the entire territory. This is essentially most knowledge work: research, writing, and other tasks that require you to create output, but that output doesn't need to be right now, like in a debate.

For example, you can know that X person say something important about Y topic, but not need to know precisely what it was – just look it up later. However, you do still need to know what you're looking for, which is a kind of reference knowledge.

--

What is actually new lately, in my experience, is that AI tools are a huge help for situations where you don't have either Type 1 or Type 2 knowledge of something, and only have a kind of vague sense of the thing you're looking for.

Google and traditional search engines are functionally useless for this, but asking ChatGPT a question like, "I am looking for people that said something like XYZ." This previously required someone to have asked the exact same question on Reddit/a forum, but now you can get a pretty good answer from AI.

I like how well-thought-out the licence revocation clause of the AOMedia patent licence is. It takes effect when a licensee sues over an implementation specifically over the relevant patent claims--so lawsuits unrelated to these patent claims are allowed (so if you infringe on other patents but also implement the licensed patent in the same implementation, the rights holder of the other patents can sue you over those claims without losing their licence)--and there is also a carve-out for counterclaims, and lawsuits to enforce this licence.

But I am not sure if the first exemption is necessarily a good thing. The Apache License, Version 2.0 is broader in what may be grounds for patent licence termination. So it is a better deterrent against patent trolls (even if that means some legitimate patent claims are also discouraged).

Or Memphis, which is smack dab in the middle of a permanently Republican supermajority state, yet has three times the murder rate and twice the robbery rate of NYC.

Is there a charitable explanation for why people cherrypick a single homicide in a metro of 8 million people and somehow act like it's proof for the downfall of liberal democracy?

Especially when by most relevant metrics, illiberal democracy performs dramatically worse?

No one wants public transit!

I've spent a lot of time in Singapore, with literally the worlds lowest crime rates, highest trust in society, and best mass transit in the world.

It costs 100K USD to get a SHITTY car, like a Toyota Prius.

Everyone in Singapore is desperate to make lots of money, is desperate to buy a cool car, and is desperate to never step one foot onto the transit system again.

Mass Transit is a cope for being poor, even in a society with no crime and the highest trust in society. Using it is admitting that "I failed to make enough money to get out of here"

We have car culture because everyone wants it. Americans can literally buy a C8 corvette factory order at 20% off MSRP right now. The world salivates at such deals and is extremely jealous of our way of life.

Liberals who try to kill car culture are exactly why Trump got elected and why he's so popular right now.

> Because it seems to me that, for much of Signal's (often paranoid) audience, they'd much rather use one of the backup/sync providers they've already verified trust of, than have to additionally trust some new backup service provider.

I wonder if those folks are the ones actually asking for backups. Personally I couldn’t give a shit about my messages from more than a week ago and part of that has to do with privacy. People concerned with privacy might also be more likely to have disappearing messages on which is the exact opposite of a backup. I honestly wonder who this is for exactly. From reading other threads, are people using this as their primary media backup basically?

This is not a problem with public transport but with utter lack of urban planning and convoluted social dynamics in the USA.

Dense cities and lack of urban sprawl reults in awesome places to live and you don't need to even use public transport in those as everything is just close by.

Also - IMHO the problem with the USA is more focus on competition (you have to "win") instead of cooperation hence more fracutred society that yields more povery and "not-nice" public spaces...

> The worst argument anybody can make is "but that's just life in the big city!" If so, then I'm not going to live and raise my family in the big city. Airy-fairy principles of efficiency or an arguable notion of convenience will not take precedence over safety and quality.

I live in a rather smallish city/town (~45k).

While I agree with the gist of the article, I think the AI example is poor, because we know AI can make stuff up and it's a problem. So this failure of AI to be reasonably correct weakens the argument. In the old days, you would rely on an expert (through say a book, like encyclopedia) to tell you this. The issue then becomes who you trust.

I would say your own knowledge is like a memory cache. If you know stuff, then the relevant work becomes order of magnitudes faster. But you can always do some research and get other stuff in the cache.

(Human mind is actually more than a cache because you also create mental models, which typically stay with you. So it's easier to pickup details after they get evicted, because the mental model is kept. I think the goal of memorising stuff in school should be exactly that - forget all the details, but in the learning process build a good mental model that you have for life.)

from tfa:

> Experts say the spike is driven by climate change making disasters more frequent, the rising cost of construction materials, and a flood of lawsuits in coastal states that drive up payouts for insurers.

Sure, lawsuits/regulatory issues is a contributing factor. #3 behind #1: climate.

But even so, the "regulatory challenges in CA" are insurance companies saying "we don't want to insure wildfire areas", the state saying "you need to offer insurance to everyone or no one if you want to play here because it's fundamentally abusive if you're gonna start picking your own areas (we all know you're gonna redline into only the lowest risk/highest return areas)", and the insurance companies saying "well, wildfires are too risky so looks like we'll insure no one then."

Calling that "regulatory challenges" instead of "wildfires aren't great for insurance" is kinda a shit argument.

Other than the obvious (but surmountable) technical challenges with crawling and indexing, trying to establish "goodness" for a given user is tough. For a blogger it will be "hey, you are reading this so you probably like what I like". That's often true but as soon as you try to have a centralized service with arbitrary users, it is hard to do anything better than filtering purely commercial content.
Show HN: 5MB Rust binary that runs HuggingFace models (no Python)
by MKuykendall | 2025-09-10 16:18:25+00:00
Hi HN! I built Shimmy, a lightweight AI inference server that can now load HuggingFace SafeTensors models directly without any Python dependencies.

The core problem: I wanted to run HuggingFace models locally but didn't want the heavyweight Python ML stack. Most solutions require Python + PyTorch + transformers libraries, which can be 2GB+ just for dependencies. What's new in v1.2.0: • Native SafeTensors support - loads .safetensors files directly in Rust • 2x faster model loading compared to traditional formats • Zero Python dependencies - pure Rust implementation • Still just a 5MB binary (vs 50MB+ alternatives like Ollama) • Full OpenAI API compatibility for drop-in replacement Technical details: - Built with native SafeTensors parsing (not Python bindings) - Memory-efficient tensor loading with bounds checking - Tested up to 100MB+ models with sub-second loading - Cross-platform: Windows, macOS (Intel/ARM), Linux - Supports mixed model formats (GGUF + SafeTensors) This bridges the gap between HuggingFace's model ecosystem and lightweight local deployment. You can now grab any SafeTensors model from HuggingFace and run it locally with just a single binary. GitHub: https://github.com/Michael-A-Kuykendall/shimmy Install: `cargo install shimmy` Happy to answer questions about the SafeTensors implementation or Rust AI inference in general!

Apple cares about ease of use.

If you are signed into the same Apple account on your iPhone and your MacBook, the iPhone shows up as a WiFi network option you can select without having to do any additional configuration.

It's one of those "It just works" continuity features, like sharing the clipboard between your Mac and iPhone without needing to configure anything.

If you go to Settings > Privacy & Security > App Privacy Report you can see domains contacted by an app, which apps contact a specific domain, and data and sensor access logs. Can also export it as a JSON file.

I think the data and sensor access logs is a newer feature since I don’t think I’ve seen it before, but network activity has been in there for at least a few years. The network activity is also only domains and ip addresses, nothing about protocol or what data was sent unfortunately.

It's not software zoom -- it's them doing binned pixels at 4x and then unbinning them and cropping down at 8x. Same thing they were doing on previous models for the 2x zoom, and now unlocked on the telephoto lens because of the resolution increase this year.

It's a quality drop for sure, but it's never extrapolating pixels that weren't optically there as software zoom does.

TBH aspnet core has been the most stable web framework I've worked in my life. If you have good test coverage, upgrading projects between major versions often takes minutes — because nothing, or almost nothing, gets broken. Some things might get deprecated, but the old way keeps working for years, you can chip away at it slowly over the next year or two.

You still need to make sure that everything works, but that's what tests are for, and this has to be checked regardless of your tech stack.

Of course, they had a massive backwards compat break when moving from the regular aspnet to aspnet core, here's hoping nothing like that happens in the next 10-15 years..
