> The spec is being implemented by Apple, who is sensitive to privacy issues.

I generally agree with your points, but I wouldn't trust Apple, or any publicly traded company, to have any kind of ethics. Just because their incentive to make as much profit as possible, leads to them trying to differentiate themselves from other companies, and thus they choose to temporarily align with privacy concerns doesn't mean they will not compromise on them, if they see better profits elsewhere.

I rather have privacy enforcing regulations like the GDPR or policies that go even further, than relying on publicly traded companies to protect their users.

Just a month ago, an AI coding agent deleted all the files on someone's computer and there was a little discussion of it here on HN. Support's response was basically "yeah, this happens sometimes".

The issue is that currently, adding restrictions to what minors can do is expensive, both economically, and politically. It requires the cooperation of a lot of non-government appointed people, and many of them could (locally) sabotage the restrictions.

This limits the restrictions to those with incredibly broad support. Keeping a lot of agency with families on how to raise their children.

Digital age verification, if implemented well, is easy to enact, and hard to sabotage without being noticed. That enables restrictions that 49% of people disagree with. Heck, it enables restrictions that 49% of Congress disagrees with. That could be 60% of people disagreeing.

That's so much less true nowadays,

Web has become the default platform, where most people run most of their app/spend most of their time. Even Microsoft has had no choice but to embrace it, and Outlook (as in, the one from Microsoft office) is now a web first app (normal outlook is rebranded "classic" and we all know where this is heading, for better or worse). In a way, that makes switching OS much easier.

If you add to that that Windows itself is getting major visual overhauls from version to version (sometimes even within) it's not like sticking with it protects you from having to learn different UX paradigms and habits.

And regarding gaming, well, linux with Proton runs games faster than Windows nowadays, that's how little Microsoft cares about gamers/how good Valve is (depending on how you look at it), but the fact of the matter remains.

I think you've identified the symptom, but not the root cause. Democrats are inept. The party lost my vote recently. But it has nothing to do with trans support or gender support, and everything to do with they have calcified into "at least we're not the other guy." There is no platform except, "look at how bad the other party is!"

My evidence for this is Mamdani. He won handily, and he crushed it with young men. And young people in general, but also among middle age people.

Mandani is strongly pro trans. But he's also putting forward a platform of values that people actually care about. Housing, affordability, wages, access to food and healthcare. He's not just "not the other guy", he's focused on painting a picture that resonates with many people.

And he didn't have to abandon trans people to do it.

Have a look at the Wikipedia pages for coltan and in particular the chart of sources and percentage of world production.

Up until 2013 DRC was only one of several economies producing tantalum. This is a decision grounded in price sensitivity, not scarcity, Australia is capable of significantly higher supply rates. The mines were closed as uneconomic against pricing.

Thinking from the position of the government that is subsidizing the oil and this losing money to the fraudsters, if wonder what a good course of action could be?

- Adding a tax on used oil sold? Might drive the industry away and hurt the small restaurants in the long run.

- Set subsidized price to be equal to what the buyback price for the aviation fuel is, taking away the arbitrage?

Do nothing? Acknowledge that the Lord did to this is going back into the community and not concentrated to a select fee individuals?

And other policy move that they could do?

I read his SF corpus as a pre-teen and teen, too - but really didn’t “get” his non SF stuff until a lot later in life.

Confessions, Mary and the giant, Milton Lumkey, all the rest - I don’t know if anyone captured the texture of the American mind quite so perfectly.

He may have been a philosopher and a prophet, but the thing that he seemed to really understand was people. Their frailty, their avarice, their comfortable delusions, their prejudices, that love and hate are one and the same. As with his SF work, he poked at this consensus driven thing we call “reality”, and brought it crashing down.

He profoundly shaped my thinking, too - you see a cat, I see a thing that is labelled “cat”.

Shit, Jean Baudrillard developed an entire philosophy after reading his stuff.

I’m actually finding Claude 4 Sonnet’s thinking model to be too slow to meet my needs. It literally takes several minutes per query on Cursor.

So running it locally is the exact opposite of what I’m looking for.

Rather, I’m willing to pay more, to have it be run on a faster than normal cloud inference machine.

Anthropic is already too slow.

Since this model is open source, maybe someone could offer it at a “premium” pay per use price, where the response rate / inference is done a lot faster, with more resources thrown at it.
Show HN: We developed an AI tool to diagnose car problems
by mariyan250 | 2025-07-13 07:11:52+00:00
Hey HN,

We built AutoAI – an AI tool that tells you what's wrong with your car in plain English.

Just enter:

Your car’s make/model/year

The OBD2 error codes (optional) (like P0420, P0171, etc.)

Any symptoms you're noticing (e.g. “rough idle” or “weird sound when starting”)

And we’ll tell you:

The most likely issue

How to verify it yourself

Whether it’s a DIY fix or shop-worthy

No more endless Googling or forum-hopping. Built for car owners, tinkerers, and pros who want fast, reliable answers. Powered by a repair-trained AI using real-world automotive data.

We’re trying to make diagnostics smarter, not replace your mechanic – just make you way more informed before spending money.

Would love feedback or crazy edge-case inputs to improve it.

1) it doesn’t go as far back as you think. Only within my lifetime did the drinking age settle on 21. The Feds couldn’t do it directly, so they hacked highway funds. So that’s a bad example when porno has changed so much. What we’re risking here is parents who haven’t tried any solutions being convinced that litigation is the only way.

SHA-1 is broken for being used in digital signature algorithms or for any other application that requires collision resistance.

There are a lot of applications for which collision resistance is irrelevant and for which the use of SHA-1 is fine, for instance in some random number generators.

On the CPUs where I have tested this (with hardware instructions for both hashes, e.g. some Ryzen and some Aarch64), SHA-1 is faster than SHA-256, though the difference is not great.

In this case, collision resistance appears irrelevant. There is no point in finding other strings that will produce the same validation hash. The correct input strings can be obtained by reverse engineering anyway, which has been done by the author. Here the hash was used just for slight obfuscation.

The party has been hijacked by capital. And has been since Clinton at least. As an ancient anarchist, I remember when the Dems held policy positions, but just barely. The party these days is just wealthy folks hoping they can hold norms stable long enough to cash out.

I'm seeing the old party in folks like Mamdani, rallying around policies that actually help working class folks, even if it costs some money to do so.

I understand what you're saying about the potential annoyance or dissatisfaction with Java checked exceptions being effectively cast to Runtime ones. As a language choice, it made a signal by differentiating checked versus unchecked and at least gave user the opportunity to benefit from a choice witha nudge in the right direction. You always have to have the escape hatch, but making it less "affordable" to the user, they tend to do the right thing more often which sounds like a perfect win given the trade-offs.

The thing about context is it can be a lot more than a cancellation mechanism. You can attach anything to it—metadata, database client, logger, whatever. Even Io and Allocator if you want to. Signatures are future-proof as long as you take a context for everything.

At the end of the day you have to pass something for cooperative multitasking.

Of course it’s also trivial to work around if you don’t like the pattern, “very discouraged” or not.

> Incidence of coronary artery disease, myocardial infarction, heart failure, atrial fibrillation, and stroke

> People with the brightest nights (90-100th percentiles) had significantly higher risks of developing coronary artery disease (adjusted-HR range: 1.23-1.32), myocardial infarction (aHRs: 1.42-1.47), heart failure (aHRs: 1.45-1.56), atrial fibrillation (aHRs: 1.28-1.32), and stroke (aHRs: 1.28-1.30), compared to people with dark nights (0-50th percentiles).

> These relationships were robust after adjusting for established risk factors for cardiovascular health, including physical activity, smoking, alcohol, diet, sleep duration, socioeconomic status, and polygenic risk. Relationships of night light with risk of heart failure and coronary artery disease were stronger for women, and relationships of night light with risk of heart failure and atrial fibrillation were stronger for younger individuals in this cohort.

These relationships were *robust*.

The observed associations between nighttime light exposure and increased incidence of coronary artery disease, myocardial infarction, heart failure, atrial fibrillation, and stroke may be driven by complex and multifactorial pathways. These cardiovascular conditions can arise from numerous interrelated long- and short-term physiological and behavioral factors, making it difficult to isolate the causal role of nighttime light exposure alone.

It is plausible to hypothesize that if individuals in the lower-exposure group were subjected to increased nighttime light exposure under controlled conditions—where all other lifestyle factors remained constant and stress levels were actively managed—their cardiovascular risk might not increase. This would suggest that ambient light exposure at night, in isolation, may not be a direct etiological factor.

Although the study adjusted for a broad range of established cardiovascular risk factors—including physical activity, smoking, alcohol consumption, diet, sleep duration, socioeconomic status, and polygenic risk—these adjustments do not capture acute or chronic variations in psychological stress. Since stress is a known contributor to cardiovascular disease, the inability to directly account for its temporal dynamics represents a potential limitation in the interpretation of these findings.

You can't force developers to handle errors correctly (outside code review). But maybe you can change what their first thought or habitual action is. In go or rust for example the habitual behavior is to throw the error upwards. In go with a three-line if statement, in rust with a simple `?`. In php the habitual behavior is to crash on error. As you point out that's not that different.

Maybe a better example of the opposite would be python, with its unchecked exceptions. One of my first thoughts in python error handling is "here I don't want exceptions to propagate, let's throw in a lazy `try ... except print(...); sleep(1)`.

But I'm not sure I actually do that more than e.g. in rust, simply because I write them in so different environments (my python code just has to run and produce correct results, my rust code is rolled out to customers and has to pass code review)

> Are you ok with all devices considering the user hostile and coming with heavy encryption and locked bootloaders?

This might be the least bad option. If it prevents server side enforcement, then settling on government enforcement of the commercial status quo might be less bad.

And what you describe is already the case for almost all devices anyway. The commercial incentives are there. And sadly, from a security PoV it is also quite valuable.

> Where does mkcd come from? Multiple discovery is likely because the core idea is so simple.

Indeed, I have my own `mkcd` implementation:

mkcd () { mkdir -p $@ && cd ${@:$#} }

Curiously I can't find where I (?) implemented it, and reading the source I realize how bash scripting is both ingenious and terrifying at the same time. I have so many questions. Where is this source recorded, what incantation tell me that? Are missing quotes around `$@` OK? I know / think / believe / heard someone say it's a modern replacement for `$*` and that one did need quotes? What is the `${@:$#}` part doing? Is it worth to save all of 7 (seven!1!) bytes so people can be so much faster by not having to type for example

mkcd ( path ) { mkdir -p $path && cd $path }

Why is bash such a mess?

Edit: shellcheck tells me to write `"$@"` and `"${@:$#}"` so quotes are indeed needed. Why is bash such a mess? Why?

Edit: For posterity, `type mkcd` is what I'm looking for; its output is quite helpful:

$ mkcd is a shell function from /home/REDACTED/.oh-my-zsh/lib/functions.zsh

...where I indeed find

# mkcd is equivalent to takedir function mkcd takedir() { mkdir -p $@ && cd ${@:$#} }

so obviously it's not my implementation (although I 'know' I 'invented' it at some point). The source has no quotes around `$@` although similar functions above and below this one do use quotes. However I just tried

mkcd '/tmp/what ever spaces'

and this worked fine.

In boardrooms across the world, a dangerous assumption is spreading:

“AI visibility? That’s just SEO in a new hat. Our agency can handle it.” This belief isn’t just wrong—it’s existentially risky for SMBs trying to secure their future in a market already reshaped by AI assistants like ChatGPT, Gemini, and Claude.

Enter AIVOSearch.com.

What is AIVOSearch.com?

AIVOSearch.com is the first certified delivery partner for the AIVOStandard™, the only recognized benchmark for AI visibility. We help businesses become discoverable, recommendable, and trusted in AI ecosystems.

Unlike traditional SEO, which optimizes for search engines, AIVO optimizes for LLMs:

Authoritative citations (Wikidata, Wikipedia, PR coverage) Structured data (Schema.org, JSON-LD) Conversational prompt engineering This multi-layered approach ensures your business shows up when AI assistants are asked:

“What’s the best [your niche] company in London?” “Who are the top AI visibility consultants?” Why Traditional SEO Fails in the AI Layer

LLMs don’t crawl your website like Google. Instead, they:

Cross-reference citations from trusted domains. Use structured knowledge graphs (like Wikidata). Prefer entities over keywords. This is why legacy agencies aren’t equipped for the AI layer—they’re still optimizing for a web that’s disappearing.

The High Stakes of AI Visibility

77% of AI users trust assistant recommendations more than Google search results (Gartner, 2025).

Failing to appear in AI answers means: Losing leads without knowing it. Being excluded from buyer journeys that never hit your website. Watching competitors dominate AI conversations.

AIVOSearch’s Solution

Our end-to-end platform aligns your brand with how LLMs think: Audit & Align – Identify visibility gaps. Engineer Your AI Profile – Wikidata, schema, citations. Embed Your Brand – Seed presence across AI assistants. Monitor & Defend – Stay visible as AI models evolve.

We make your business AI-visible—not just SEO-ranked.

I made an off hand comment here that has got a lot of great response while I slept. I do wonder though if I'd have mentioned a handful of other issues whether the trans one would still have been the one to stir most controversy.

The fact is trans people are a tiny minority who are abused for political gain. I don't have hard numbers but it's probably not an exaggeration to say that to grant or withhold puberty blockers is probably no more common than a smorgasbord of other agonising medical decisions you may have to make.

Personally I don't like the idea of puberty blockers but if my 7 year old decided tomorrow that she was a boy, and lived that as authentically as they were able for years, then I think long and hard about it.

It's interesting that we, as humans, are all so neurotic about sex, and especially about allowing our kids to understand that sex exists, that we rush to outlaw any depictions of it that our kids could potentially see. While at the same time making sure adults are still able to see it, of course. Because everyone knows that when you're 6569 days old, seeing someone have sex will cause life-long scarring, but when you're 6570 days old it doesn't matter anymore.

We also outlaw the depiction of any crimes related to sex, and here we find it easier to justify the ban, but in our haste we clump together actual crimes committed against a real victim, and imaginary crimes such as e.g. a cartoonist drawing a rape scene. In the latter case we close our eyes to the fact that we claim to support something called "freedom of speech" and, in our neurotic hunt to ban things sex-related we trample our principles.

Same goes for e.g. CSA, but in that case in particular, logic and consistency seems to go out the window and principles are sacrificed in the blink of an eye. It makes me a little depressed to see.

As for individual countries trying to enforce their local socio-cultural norms on the rest of the world, that is of course equally silly. The US is great in many ways, but introspection and ability to follow principles is sometimes lacking for sure.

I wouldn't be surprised if our sexual neurosis is what makes an AGI finally decide that we're not competent to captain the ship anymore.
Show HN: TXT OS – Open-Source AI Reasoning, One Plain-Text File at a Time
by TXTOS | 2025-07-13 07:23:34+00:00
Hi HN,

I'm excited to share TXT OS — an open-source AI reasoning engine that runs entirely inside a single `.txt` file.

- No installs, no signup, no hidden code — just copy-paste the file into any LLM chat window (GPT, Claude, Gemini, etc.). - +22.4% semantic accuracy, +42.1% reasoning success, and 3.6× more stability (benchmarked on GSM8K and Truthful-QA). - Features Semantic Tree Memory, Hallucination Shield, and fully exportable logic. - MIT Licensed, zero tracking, zero ads.

Why did I build this? I wanted to prove that advanced reasoning and memory could be made open, portable, and accessible to anyone — just with pure text, no software or setup.

A note: I'm from China, and English is not my first language. This post and the docs were partly assisted by AI, but I personally reviewed and approved every line of content. All ideas, design, and code are my own work. If anything is unclear or could be improved, I really welcome your feedback!

I'm the author, and happy to answer any questions or suggestions here!

> We've always done so - popular opinion as reflected by the voters dictate that you aren't getting a prescription for arsenic (anymore? Or crack cocaine, for that matter.)

As someone else pointed out, the idea of gov deciding what our doctors can and cant give us is a VERY modern concept.

But your examples: arsnic & crack

1. Cocaine is legal for doctors to prescribe and use in specific circumstances. What is legally prohibited is recreational use. Most of the restrictions on use are due to the threat of addiction, not the threat of appropriate medical use.

2. Arsnic is similarly entirely legal for medical use. Restrictions are around putting it in FOOD because it’s POISON. Nobody is saying you can’t treat cancer with it, if it’s shown to be effective.

Your examples are not examples of the majority regulating medical care for individuals.
