I disagree. The location is definitely a factor. If you live within 300 feet (about 100 meters) of a multi-lane highway, then depending on the wind patterns, you are definitely getting more exposure to pollutants that come from cars, trucks, or their brakes and tires. But no one in California is ready to talk about addressing this because it would require radically changing the status quo.

Incredibly, the noise insulation between floors and ESPECIALLY walls in both hotels around the world and even expensive, modern apartment buildings in Manhattan is absolutely atrocious. So I end up booking Airbnb's when I travel and renting top floors whenever I can.

I find the build quality of new buildings (again, even uber luxury apartment condos) in the U.S. absolutely crap compared to Europe (I'm thinking especially of France and Germany).

Over here on HN you have a strong contingent of people who push pro-density, pro-city, and anti-car. But some people (like myself) who suffer from a sensitive sleep are deeply affected and consider moving to the woods away from people just for this problem. I find the 'SLAM' sound of doors (in New York there's a spring loading per building code), the stomp stomp of upstairs, and the bass music of adjacent neighbors to be deeply disruptive from a psychological perspective.

> You already have to show ID to see rated-R movies in the US.

The law doesn't, in most places, require theaters to demand or log ID (it sometimes requires them to deny admission to people under 18 without parent or guardian permission, and in some places doesn't even do that, with any restrictive policy being a matter of theater policy following private industry group recommendations), and they mostly don't even do the former unless the patron appears, to the ticket seller, to be underage (and even then, IME, its iffy, probably because while that's generally theater policy, the ticket sellers aren't minimum wage earners, likely teens themselves, and not closely supervised.)

Nobody claimed we need 100% precision (or, more to the point, 100% certainty). But I would argue the level of our convictions should be proportional to the risk and level of certainty.

To the point being made, for most Americans the cost of updating your building envelope and fenestration is relatively high. Yet if we look at the accuracy of the data (compared to the medical device standard), it’s moderate accuracy. So we’re taking a high risk for something that we’re only moderately confident will work. That’s not a good tradeoff. There may be interventions that are lower risk that make for a more balanced approach.

“Move fast and break things” as a general philosophy is a risk-blind approach.
Ask HN: What tools have you tried to run AI locally on mobile?

Everyone has a phone, and it is the place where we need most privacy. Who have tried running LLMs on mobile or built local AI projects on mobile?

Out of curiosity: 1. What tools have you tried? 2. What specific step killed your motivation? 3. If you succeeded - what was your use case?

You don't know what their intentions are.

They are like the police or the car salesmen: they do this every day or so, you do it once every 5 years. If you're not careful, you won't even know what happened there, not until you see the consequences. Protect your own career and interests.

The best thing one can do both for oneself and the remaining employees is vote with their feet. If enough employees do that, things may change. Don't burn bridges when you leave.

I work for a boss whose anonymous yearly reviews are atrocious every single year. Nothing ever changes, he's still running the department. The organization is rotten to the top, and no honest feedback will ever change that. I bet not even most of us leaving.

That's nice, but tiktok seems such a weird way of sharing it. I mean, how can you search for certain recordings/performances or discuss it? It's just an ever going list of movies, with no structure, you cannot even predict what comes next... It seems hard to follow someone at all. You just have to wait until a certain clip comes along. It's total chaos. But like I said, maybe I am just getting too old.

It’s not that dumb- if a human gets exposed to space the water in their exposed tissues will boil off, leading to evaporative cooling. In a vacuum, evaporative cooling can get you ~arbitrarily cold, as long as you’re giving up enough fluids. I don’t know whether you freeze over or dry out first, but I’m sure someone at NASA has done the math.

I don't follow the argument. In the sphere of gender roles, for example, I absolutely believe that adults should be allowed to set up whatever arrangements are best for them. I would never walk up to a traditionalist couple and demand that they set up their relationship how I'd prefer. But I would still find it very concerning to hear that most young men expect their wives to not work or not make male friends, even if young women accepted it.

It would at least be an interesting project. If someone put the elbow grease into it it is distinctly possible that an XSLT stylesheet could be not just converted to JS (which is obviously true and just a matter of effort), but converted to something that is at least on the edge of human usable and editable, and some light refactoring away from being decent code.

As much as I love AI/LLM's and use them on a daily basis, this does a great job revealing the gap between current capabilities and what the massive hype machine would have us believe the systems are already capable of.

I wonder how long it will take frontier LLM's to be able to handle something like this with ease without it using a lot of "scaffolding".

I have a mac m4 pro and it's 2 minutes to compile all of Deno, which is my go-to for bigass rust projects.

```

> cargo clean && time cargo build

cargo build 713.80s user 91.57s system 706% cpu 1:53.97 total

> cargo clean && time cargo build --release

cargo build --release 1619.53s user 142.65s system 354% cpu 8:17.05 total

```

this is without incremental compilation. And it's not like you have to babysit a release build if you have a CI/CD system

Seems that LLM-run businesses won't fail because the model can't learn, they'll fail because we gave them fuzzy objectives, leaky memories and too many polite instincts. Those are engineering problems and engineering problems get solved.

Most mistakes (selling below cost, hallucinating Venmo accounts, caving to discounts) stem from missing tools like accounting APIs or hard constraints.

What's striking is how close it was to working. A mid-tier 2025 LLM (they didn't even use Sonnet 4) plus Slack and some humans nearly ran a physical shop for a month.

Such a strange position to take indeed. I dont see people clamoring behind Apple when they do proprietary things - iMessage protocol, Bluetooth improvements for Airpods, private APIs in Apple Watch.

Apple's "life saving" Apple watch features are only accessible on premium devices. "Privacy is a human right" is also only possible if you buy their devices. It doesnt go around making it free to everyone, and nobody seem to be saying "if you believe in that, then why dont you make it accessible for people from all socio-economic classes?"

Hello HN!

As a long-time professional Rust developer. I've always been frustrated by the difficulty and "hackiness" of producing bindings to other languages, whether a frontend, an FFI library, etc.

Not just in Rust but in any language.

After many years of trying existing solutions and trying to make my own, I've finally developed a solution I'm very happy with.

RTK (aka Rust Type Kit) allows you to write Lua scripts that perform queries on your code, such as method calls to Axum's `.route`, function definitions, and more, and then receive rich type information including all argument types, function paths, proc macro attributes, and more.

Your Lua script can then read this information and emit an output file in any language of your choosing. Or, you can emit compiler errors and use it as a linter of sorts. You can even directly re-emit Rust code itself and use this as a richer proc macro solution!

The code example is a bit verbose, so I encourage you to take a look at the repo's README. I look forward to hearing your thoughts, or any usecases you may come up with!

A friend of mine bought a house with a heat pump, poorly installed, that didn't work at all. Had to just install a petrol boiler and hook it to the same radiators. Contractor that originally installed it is out of business.

And in America, the dumb simple reason is that there is no need for them with natural gas being so absurdly abundant and cheap. American natural gas prices are almost as low as Russian internal prices. Might as well ask why aren't there any heat pumps in Russia. These devices are for rich, highly educated, energy-poor markets.
Show HN: I made a tool to convert recipes to an easy reading graphical notation
by ekglimmer | 2025-06-27 17:40:31+00:00
Hi HN,

I have been working on a project which can automatically convert a recipe to the tree/graph/tabular style notation that pops up on HN every now and then. It's still early days but I am keen to hear about improvements I can make to the recipe presentation.

For reference, the earliest example I have seen of this style of notation is from 'Cooking For Engineers' (https://news.ycombinator.com/item?id=30797907) but I have seen other, similar notations from time to time.

This is my take on the notation, as well as the ability to convert recipes automatically. In the future, I would like to see it become my own personal kitchen/recipe management system but I would first like to improve the recipe display options.

It uses ChatGPT to format the recipe into a JSON tree structure, which is then rendered with CSS grid. So far it works well enough but there is definitely some recipes that are impossible to render, and of course ChatGPT will occasionally spit out less-than-useful trees. I have been using AppWrite for the backend.

Curious to hear everyone's thoughts and what people might like to see!

> The huge border between Russia and Ukraine is completely flat grassland. This means that to Russia, Ukraine joining NATO is an unacceptable risk because that border is impossible to defend against NATO tank invasion, and the flatness go all the way to Moscow.

This can be reversed and then Russia was supposed to be able to use its supply of 20000 prewar tanks to just swipe through Ukraine and stop at Uzghorod like an Iraqi 2003 style thunder run. It tried to, but failed miserably.

Maybe 19th and early 20th century doctrines are no longer alive with guided ammunition and spotting drones constantly in the air. Actually we can see it in Ukraine today, the moment when Russia setups an armored column it will often get disassembled by drones and artillery kilometers before reaching the zero line. It requires major effort and sacrifice to move frontline few meters on open terrain.

My mum hears it too, but the local authorities simply claimed they couldn't hear anything during that brief moment. They’d have to stay overnight to really hear and feel it — inside a room, not just in a public space. It even vibrate my eardrum like I'm sitting on an F16 pilot seat.

I don't hear it in other districts.

I wish there were an expert or researcher interested in these areas: residential buildings, shops, parks, churches, and schools.

Had they said "the array will be so large it'll have its own gravity." then you'd be making a valid point.

But they didn't say just "gravity", they said "gravity well".

> "First, let us simply define what a gravity well is. A gravity well is a term used metaphorically to describe the gravitational pull that a large body exerts in space."

- https://medium.com/intuition/what-are-gravity-wells-3c1fb6d6...

So they weren't suggesting that it will be big enough to get past some boundary below which things don't have gravity, just that smaller things don't have enough gravity to matter.

In high school they had a few information kiosk computers spread around the various buildings; two in the library, one in the main reception, one in the cafeteria, and one in the mostly unused hallway right outside the computer club room. They were locked down so you could only navigate some intranet pages using a rudimentary on-screen keyboard, with the rest of the hardware in a locked cabinet.

Guess which one got digitally defaced a couple of times each semester. Guess which ones got left alone. Genius move by the IT guy. Every time it happened he would come talk to the club members about the difference between whitehat and blackhat hacking but other than that nobody ever got in trouble.

> It’s difficult to keep moving knowing that we don’t have the ability to opt out of the way our whole society works.

Pretty much nobody ever did, in any society, with few exceptions. "Going to America" was one exception, and then "going west". But for most people, for most of civilization, that has never been an option.

And, in fact, the whole system is stacked against us less than it has been for most of the history of civilization. You aren't a serf. You aren't a slave. You aren't an indentured servant, or bound to a ruler or leader in any way.

But I think what many people are feeling is the first derivative. There was a time when the system worked better for people (at least for white males) - say the 1950s or 1960s. People can feel the first derivative being negative. They feel the loss of something. I think that's behind the surge of this sentiment.

> Can Claude run a small shop?

Good luck running anything where dependability on Claude/Anthropic is essential. Customer support is a black hole into which the needs of paying clients needs disappear. I was a Claude Pro subscriber, using primarily for assistance in coding tasks. One morning I logged in, while temporarily traveling abroad, and… I’m greeted with a message that I have been auto-banned. No explanation. The recourse is to fill out a Google form for an appeal but that goes into the same black hole into which all Anthropic customer service goes. To their credit they refunded my subscription fee, which I suppose is their way of escaping from ethical behaviour toward their customers. But I wouldn’t stake any business-critical choices on this company. It exhibits the same capricious behaviour that you would expect from the likes of Google or Meta.

As a performer and small site owner, am I to understand that you usually sell sexual material and you don't perform any check to make sure that they are not kids? How are you making sure that users are of age other than the "I am 18: ENTER" button? Maybe you take credit cards and can check their age through that? Do you take crypto or wallets that don't require 18+?

The atmosphere and gravity are only some of the problems with spinlaunch. Spinlaunch rotates at 600 rpm. That means the projectile is tumbling at 600 rpm when let go.

Maybe for solid masses not in an atmosphere, meaning the payload can be a ball and doesn't have to have a pencil shape and doesn't need to point in any particular direction, maybe that can work to simply lob rocks or aluminum ingots into earth orbit.

Except just think about that for a second. Lobbing rocks from the moon towards earth...

And why would we want to do this anyway? What resources are so valuable on the moon that it's worth getting them that way?

The payload would actually have to have rockets, fuel, computers, heat shielding, and a means to reshape itself so that it can: stop it's own tumble after launch, deploy glide wings, and survive reentry to a controlled landing so that we don't have to use rockets from Earth to go collect the payload from orbit.

It's all surely physically doable but why?

Even if orbit was the final usage destination not Earth, like to build stations, that still seems like a stretch.

If you create hypothesis tests that are not written in or specific enough then you’re right you’re not gonna be able to do science

Check out the location of these condos in downtown Toronto built alongside the Gardiner Expressway, a very busy 90km/h (~55mph) highway: https://maps.app.goo.gl/TGLCBJGbrSEkAm7W6

The satellite view shows many units in multiple buildings directly next to this highway with no noise protection: https://maps.app.goo.gl/JA4jMPSSYsDBq5my5

Years ago I lived near a busy four-lane road with what seemed like a reasonable 60km/h speed limit. However, when it rained, the noise from the car tires on the wet road made it difficult to hear music from my radio. It was very unpleasant to leave the balcony doors open, as the constant din starts to work its way into your brain and make it very difficult to focus.

There is no way for an ISP to differentiate between an infected router or IoT device and an infected PC due to the user's own neglegence.

If laws like the Cyber Recillience Act have been put into effect long enough for us to see a significant improvement in device security, then we can softly begin to rule out that cause and focus on the user.

We are not there yet, because (imo) devices are still not properly secured enough for us to go straight to blaming the user.

As reference (for feature comparison or whatever) here are some tools I use to keep things in sync, some have already been mentioned:

rsync - I think everybody knows this rclone - modern feature packed tool similar to rsync, but also more complex croc - a modern cross platform file transfer utility syncthing - sync service with web gui to keep multiple devices in sync LocalSend - An open source GUI tool also for mobile devices restic - a tool for encrypted backups with rolling hash deduplication immich / ente.io - Photo backup app with frontend and backend zfs - filesystem with send and receive

All of these are (partly) open source and free to use. Hope it helps.

Lisp is "functional" in a 1970s sense in that it has functions as first-class objects you can pass as parameters to other functions, but those functions are basically subroutines which can have side-effects and un-functional behavior. As you allude to, this is pretty much par for the course in procedural languages now, and OO As She Is Spoke is procedural with some extra stuff added. Even garbage collection is common enough now that languages which don't have it trumpet the fact and make it their whole personality. Lisp is heady and revolutionary if your baseline is FORTRAN and maybe C, in other words, unless you actually do begin to write your own macros, at which point the C people begin to look at you funny.

Haskell is functional in that it demands its functions be functions, not subroutines. A function has inputs mapped to outputs and no side-effects. Functions can be composed and composition always works. Haskell uses monads to represent the regrettable fact that having an impact on the outside world is, in a very real sense, a side-effect, so it marks all side-effecting functions with an indelible stain. Haskell requires a different mode of thought from Python, or even from C++, and it's definitely not another Lisp.

Yes, this smells like an attempt to get some kind of reflected glory from AI while not recognizing that consumers, who already hold car rental companies in low regard, are likely to assume that the move is hostile to them.

(Many other sources discuss this aspect of AI: the necessity of trust from the consumer. I think we'll see a lot more of this in the coming years, either because big tech simply ignores the problem and overrides the objections by volume, as in the case of online reviews, or because there'll be some high profile flameouts.)

Of course, this is the same Hertz that torched 2 billion dollars on an EV gamble that failed, and whose stock price has been on a slide ever since the pandemic. Back in 2020, Hertz was trading just above Avis. Five years later, and Avis is $176 and Hertz is $7.

Very cool. I just wanted to say how much I enjoyed reading through your detailed flight logs — the way you’ve documented your experience, from distances and time in the air to the nuances of roles (P1, P2, PICUS), was fascinating.

As someone concerned with these matters — developing SpinStep, a quaternion-based library for modeling orientation and vector state evolution in physical systems — I found myself unexpectedly inspired by your data. It got me thinking: could these kinds of spatiotemporal logs, with their emphasis on direction, roles, and environmental influences, be approached through something like rotational state modeling?

For example:

.Aircraft headings and orientation changes could map naturally to quaternions.

.Role transitions (e.g. P1 ↔ P2) resemble discrete state changes within a continuous system.

.Wind effects or flight network patterns might even be modeled as external fields influencing orientation over time.

I hadn’t envisioned SpinStep in this context, but your log offered a compelling perspective. Whether or not it leads to something concrete, I just wanted to thank you for the inspiration.
