> The displays are gradually less important because a growing fraction of the population are already carrying a display with wireless networking, on a personal device the UI can show you your exact route and where the bus you need is now etc.

That is not my experience at all. I use busses every day and I always use the posted times and don't want to look for it on my phone. There are a handful of bus stops on my common routes without displays and I always hate it.

I'm not sure there is a critical mass of people actually looking at the apps for real-time departure information, at least not in my city (Vienna Austria).

I think your love and dedication to your child are amazing! He or she is lucky to have you as a parent.

---

I am not a doctor and I'm not qualified to give you medical advice; the following should not be construed as medical advice.

My first suggestion would be to get qualified professional help, not HN help. In your shoes I would go to a physical therapist (or occupational therapist, perhaps) off the bat. There could be a functional, non-medication intervention that would solve the problem. For example, perhaps deep rest, a stretching/flexibility regimen, or aquatic exercise would help. (I don't know; I'm just throwing out hypotheticals.) And the PT might have good advice for approaching your doctor if medical treatment is needed.

If the Danish medical system is not working out, consider traveling elsewhere and seeking quality treatment there, if only to get a second or third opinion, but also to get suggestions of ways you could approach your doctors back home.

Good luck, and I hope you get the results you're hoping for soon!

I came across a really interesting video yesterday (https://www.youtube.com/watch?v=Aubi3cK8Ym0) that touches on brake-dust pollution. It also explains how regenerative (kinetic-energy) charging can cut down on heat pollution, something I hadn’t realized before. That’s actually a big deal for underground metro systems; for instance, the London Tube keeps getting hotter every year.

Maybe a bit off topic, but years ago I had a home linux server, used for usenet/torrenting. I was just poking about on it one day and ran some variation of netstat and could see a connection with a 6.x.x.x range IP address, which stood out. I didn't know a whole lot about networking at the time (still don't), couldn't say if I had misinterpreted what I saw in the netstat output. But it stood out so I looked it up and hoo-boy, it was a shock to see who owned that IP range, Army Information Systems Centre. I chalked it up to them maybe running a torrent tracker or something, or was the DoD in my PC?

I love this idea, not least of all because it was one of the things on my "todo" pile that never gets any smaller. Congratulations guys. I miss the small community I found on the early Internet, before Eternal September. When small groups of people get together in a space that is both "confined" and "limitless" great things can happen.

I actually wondered about this myself, so I asked Gemini with a long back and forth conversation.

The takeaway from Gemini is that subscriptions do lose money on some subscribers, but it is expected that not all subscribers use up their full quota each month. This is true even for non-AI subscriptions since the beginning of the subscription model (i.e. magazines, gamepass, etc).

The other surprising (to me, anyway) takeaway is that the AI providers have some margin on each token for PAYG users, and that VC money is not necessary for them to continue providing the service. The VC money is capital expenditure into infrastructure for training.

Make of it what you will, but it seems to me that if they stop training they don't need the investments anymore. Of course, that sacrifices future potential for profitability today, so who knows?

UK stats are different: https://www.zap-map.com/ev-stats/ev-market , possibly due to the shorter max travel distances.

> As of the end of June 2025, there were 2,450,462 plug-in cars, with over 1,585,000 battery-electric cars and nearly 865,000 PHEVs, registered in the UK.

> There are more fully electric cars than there are plug-in hybrids on UK roads and the gap has been widening. In 2021, fully electric cars accounted for 60% of all plug-in cars but with the increase in options, range and popularity of fully electric cars, and by May 2025 this has increased to 65%.

(That stat does exclude non-pluggable-hybrids, but those are kind of pointless stalling of the transition off petrol)

Dude...we are talking about Hawaii. The largest of the islands is just over 4000 square miles. None of the others are over 750 square miles. People drive a lot less in Hawaii than in most of the rest of the country.

The average is 8900 miles per year which is a little under 24 miles per day and a little under 750 miles a month.

If you can charge with solar at 6 kW on a typical EV that will give you about 20 miles per hour of charging. If you can do a little over an hour a day you will be covered.

If you find plugging in for an hour a day to much of a hassle it is under 9 hours a week or 37 hours a month.

> Yep. Dark patterns you can see are not that dark by comparison, we will need another word for coming dark patterns disguised in llm responses

As someone else said, you can probably filter responses through a small purpose-built/trained LLM that strips away dark patterns.

If you start getting mostly empty responses as a result, then there was no value prior to the stripping anyway.

> You will have to learn C eventually

Quite a bold assertion. I learned C in university—and while I am sure it was beneficial to my development as a programmer—there have been exactly 0 times since then that I have needed to read or write C.

That’s just my anecdotal experience, but I’d reckon many people can have a very successful professional career while never having touched C.

Meta: broken all possible privacy laws with "localhost tracking"

Me: f*ck off, enough, time to buy pixel and grapheneos

Govt: meta pays _me_ $32bln for breaking _your_ privacy. What? You want to defend yourself? You are a criminal, then! That way, Meta wouldn't pay me again!

Monopolies are the only source of crime throughout history.

Monopolies are the brightest sign of collective irresponsibility.

Monopolies are useless for society in their attempts "to compete", since they are only trying to leverage their size and thus eventually bring harm.

With these days $ numbers, they can be so big, that they create a cantillion effect on market just because of their existance on market even without manipulation. Should be resected, dissasembled and limited in their further growth, including govt bodies, incentivized to decentralize.

> something surprising that can happen during the process, which is that, for sufficiently similar models, behaviour can be transferred from student to teacher

By "behaviour" they mean data and pattern matching, right? Alan Turing figured that out in the 1940s.

LLMs aren't black boxes doing voodoo, like we like to tell politicians and regulators. They're just software processing massive amounts of data to find patterns and predict what comes next. It looks magical, but it's maths and stats, not magic.

This post is just selling second-hand ideas. And for those of us outside the US who spend all day reading scientific papers, sorry Anthropic, we're not buying it.

How many chargers per hundred spots do his work or grocery store have?

Typical car density for my nearest three grocery stores is 25-100 vehicles fluctuating during three or four peak hours. The highest number of chargers at any of those stores is 8, followed by 2 and 0; of those, 8 have been out of service for the past 60 days because someone is playing negotiation hardball with the charging services provider.

When the chargers were working, they were nearly at capacity for the entire day, at current (low) levels of electric car fraction of the population; there's no way they're prepared to cope with a full conversion, at which point the same power density and distribution problem that impacts multifamily parking garages instead (or as well!) affects grocery stores.

This attack/feature hinges on the

config.prejoinConfig.enabled=false

config (which implicitly decides weather or not a prejoin dialog is shown)

but this makes me wonder

1. why can you set that config in a URL? Allowing users to set it for them-self seems fine, but allowing rooms or URL to use it seems ... off.

2. how many other sites have this attack surface (e.g. MS Teams) just more obscure

3. actually the moment the attacker controls JS probably *all* other video conference systems have the feature, through potentially needing a lot of additional work. In which case maybe just being straightforward and open about it is fine? But the cost of such an attack is just a very bit too low compared to other conference systems.

AI Overviews are great for users but brutal for publishers. Studies show sites lose roughly 40–50% of clicks when these summaries appear. It feels like another step toward Google keeping users on the SERP, instead of sending traffic out.

If this sticks, creators will either need to optimize for being included in the AI answer or focus more on direct channels (newsletters, communities) to survive.

This. This, this, this. I cannot stress enough how critical this point is. Either we invest a trillion dollars in electrifying parking spots or we invest that in building out transit and bicycling systems. None of them will ever be profitable over the long-run, so we continue with gas vehicles. I would so much prefer not to have to drive to the grocery store when I don't have 2 hours round-trip to spare on four intersecting transit schedules, or to risk life and limb every time I want to try and bicycle those 2.5 deadly miles across four highway on/offramps where vehicles ignore every "no turn on red" sign in the region and police that don't enforce.

Banning gasoline vehicles is the goal. In the U.S., all known solutions require capital investments that corporations can't extract a 'growth in profit growth over time' from, while disadvantaging the vehicle owners caste. Solve that, and you'll solve a lot more than just gasoline vehicles.

@AllegedAlec Rye is fully runtime homoiconic. Rebol had great emphasis on DSL-s (dialects), and Rye has them too (validation, math, ...), but tries to be more conservative with them, because the main Rye DSL should be quite flexible.

Instead of DSL-s Rye focus much more on constructing specialized, also limited and isolated contexts (scopes), that have just the functions you need or just the custom functions you need, while the evaluation mechanism doesn't change (is the one you (or LLM) already know(s)).

I haven't thought about contexts + LLM-s yet. I will read the PDF you referenced with interest! Here is a little more info about contexts: https://ryelang.org/meet_rye/specifics/context/

> going 90 in 120 region of highway without any reason, presumably saving last bits of battery (that has at least some rationale, if they do it due to ie fear then they should not be driving or having license).

Was very concerned until I realized you were talking about kilometers and not miles.

Otherwise, I'd hope the average driver would firce themselves to drive slower than 120mph out of some sense of fear, or at least a sense of self-preservation.

For relief of tired muscles I'd suggest (after taking to your doctor in regard to a health check in case there's some other matter that needs to be considered,) purchasing some pure 100% unflavoured Creatine Monohydrate. Ignore the higher amounts for muscle building, or the initial loading - view it instead as a daily supplement, and take about a third to half of the rate given in directions for the first couple of weeks and then vary it accordingly.

Note be mindful of how much you normally do in a day and try and stay at around that level of activity. I was using it about 30 years ago and encouraged my parents to try it out, not at high rates either, both stopped taking it after a few days as it gave them bad cramps - when I dropped by I discovered they were well and truly over-doing it (such as the daily weeding a fairly large vegetable patch) getting though what would have normally been done in a week, in a singular day.

As for muscle mass, that's different, as people get older it seems unfortunately the skin gets thinner as well as losing some mass around muscles - when one is younger, inactive periods don't incur much muscle change as it does when we're older. There are new medications coming but they are either expensive or will need to pass tests for regulations.

If you are new to Kubernetes or want to level up your Kubernetes game then this course is for you - its FREE.

yes it's a browser setting to "remember mic/camera permission for given site"

to which extend this "remember" is there by default, can be disabled through system config/MDA etc. is probably very

lastly iff that is a default for Safari on Mac I wouldn't be surprised if that was not only placed their to protect your safety but to annoy you and push you to use Mac, it would fit into a sad list of similar things done by Apple to push people to go through their app store. But then more safe is still more better for many users.

Really? No one for example complained about the attractive main character in Stellar Blade? And no complaints about how the characters look in Marvel Rivals?

That aside you can word it however you want "attractive", "unrealistic beauty standards", "sexualized", or even call it "not having enough representation" but everyone knows what you are actually talking about is getting rid of good looking women in video games and not giving players a choice of having a "representative selection".

As for it being purely a business decision by companies, how is Concord doing? The point being both men and women like having beautiful characters so say that it’s a business decision to have ugly characters is just not true.

> Or do something like have the braking come on gently at first then harder.

You can do this by letting go of gas pedal slowly. I have "current amount of fuel used" info in my car (liters/100km), it shows pretty clearly, that when going fast and slowly letting go of gas, amount of fuels slowly goes to 0. If I let go of gas fast, the engine is intelligent enough to not close throttle as fast as possible, still probably takes 1 second.

> More modern engines have electronically controlled throttle plates, and this is definitely somewhere you could do something clever like you suggest - cutting fuel flow but also maximising airflow when there is zero throttle input.

They cut fuel flow and close throttle plate almost completely but still allow some small amount of air, in order to actually do engine braking. If you need to coast, you can apply clutch in manual. Don't know that much about automatic, but from what I've driven, they use "lift gas" as a "engine braking" signal, so probably they can't really coast that good.

As you said, you are not allowed to install it hence it is forbidden for you, you need a professional to do it for you. It is 400€ to buy a unit, but if you ask an professional shit cost 2500€ at least. r32 aint toxic and it is only mildly flammable and a few 100 Gramms, meanwhile anyone can use their natural gas cooker in their house alongside a 11kg bottle. I don't see the electrical hazard if you plug a small unit into a normal power socket. They teach how to wire a plug in school in the UK.

>Passengers might be encouraged to wait for a following bus, with the inducement that it’s less crowded.

>Northern Arizona University improved its service by abandoning the idea of a schedule altogether and delaying buses at certain stops in order to maintain even spacing.

FYI the real solution is bus lanes so busses don't get stuck in traffic. But for that, you need to make space that isn't for cars. So you won't get it in Arizona.

I've got both at the moment on my two Hondas. Both manual, one with a throttle cable and one with throttle-by-wire. There's quite a bit of difference in how they handle off throttle. The cable will just slam the throttle shut if you just jump off the pedal (obviously) and it jerks pretty hard. The throttle-by-wire car hangs the throttle a little when letting off and doesn't just immediately start decelerating. Then it's much smoother once it does start slowing down. The ECU definitely doing something to smooth it out.

Funny because the cars build dates are only 2 years apart, 2005 and 2007, and they're both K20 engines but the engines handle so different.
Show HN: Grammit – Local-only AI grammar checker (Chrome extension)
by scottfr | 2025-07-24 10:01:45+00:00
Hey HN,

I wanted a grammar checker that didn’t send my writing to someone's servers, so we built Grammit, a Chrome extension that runs grammar checks locally using an LLM. Your text never leaves your computer during checking.

Because it uses an LLM, it catches more than spelling and grammar. For example, it can correct some wrong statements like “The first US president was Benjamin Franklin.”

We used many new web features to build this, such as:

- Chrome’s new Prompt API to talk to the local model.

- Anchor Positioning API to place the UI with minimal impact on the DOM.

- CSS Custom Highlights API for inline error marking.

- The new CSS sign() function to create CSS-driven layout with discontinuities.

Part of the fun of being early adopters of bleeding edge tech is we’re discovering new Chrome bugs (e.g., https://issues.chromium.org/issues/428354426, https://issues.chromium.org/issues/428039224).

I’d love your feedback on:

- Where the UX feels rough - What you think of the corrections and suggestions - Other local AI features you'd find useful

Happy to answer questions about the tech or the Prompt API. Thanks for trying it out!

Ok, your point is valid. You can't disconnect from the grid if you want all the benefits that the grid bestows.

But then the reverse is true - if you are enjoying the benefits that the grid bestows then you need to pay for that. Yes, in the past the "variable benefits" and the "fixed benefits" were all rolled into a single payment, which was based on variable use. It was "simple" and "mostly fair".

Now that a single payment is no longer fair, it makes sense that the benefit-cost needs to be split into a variable, and fixed, component. That's not some sort of new tax, or penalty for solar users. It's simply costing benefits correctly.

So we return to the point - if you want the benefits, then these are the costs of that. If you don't need the benefits then you can disconnect. (Personally I like the benefits, and hence pay my share of the fixed costs.)

> In 2015, Pennycook made headlines when he co-authored a paper demonstrating how certain people interpret "pseudo-profound bullshit" as deep observations

To be fair, the person doing the observing and the analysis shouldn’t be so biased. You don’t start a study with your thumb on the scale.

Much like the conspiracy theorists, Pennycook obviously has his own model of the world. One that’s shamelessly subjective and fueled by self-gaslighting. Someone in Pennycook’s position should know better; and the media should be more transparent about such shortcomings.

The irony would be funny if it wasn’t so embarrassing.

if a new base model nissan versa was $40k and an F150 was $18k, then maybe I could agree with that. of course I don't even need to point out the reverse is true.

auto manufacturer lobbyists may have been successful at convincing the government to incentivize the production of more expensive, more profitable vehicles, but it's not like there aren't still cheap small cars that everyone knows about and would fulfill 90% of people's needs for half the money, yet they spend on average $50k for a 4,000lb SUV, to never carry more than 4 people and some groceries.

maybe lobbying got the price of SUVs down 10% relative to smaller cars, and sure some people considering a smaller car might upsize because of that. but I don't think it's possible to discount the cultural component when you look at what people in the US buy. and if people fall for that because of advertising, that's essentially cultural.

> For some issues, you might get different advice in the Scottish one than the UK-wide one

its not a UK wide one. The home page says "NHS Website for England".

I seem to remember the Scottish one had privacy issues with Google tracking embedded, BTW.

> So, if you've gone into labour somewhere in the remote Highlands and Islands, you'll get different advice than if you lived in Central London, where there's a delivery room within a 30 minute drive

But someone in a remote part of England will get the same advice as someone in central London, and someone in central Edinburgh will get the same advice as someone on a remote island, so it does not really work that way.

> if you live in the USA, but US medical advice is wildly different to the UK.

Human biology is the same, diseases are the same, and the difference in available treatments is not usually all that different. This suggests to me someone's advice is wrong. Of course there are legitimate differences of opinion (the same applies to differences between
