Sir your experience is unique and thanks for answering this.

That being said, someone took the idea of you saying LLM's might be good at subsets of projects to consider we should use LLMs for that subset as well

But I digress because (I provided more in depth reasoning in other comment as well) because if there is an even minute bug which might slip up past LLM and code review for subset of that and for millions of cars travelling through points, we assume that one single bug in it somewhere might increase the traffic/fatality traffic rate by 1 person per year. Firstly it shouldn't be used because of the inherent value of human life itself but even from monetary sense as well so there's really not much reason I can see in using it

That alone over a span of 10 years would cost 75 million-130Million$ (the value of life in US for a normal perosn ranges from 7.5 million - 13 million$)

Sir I just feel like if the point of LLM is to have less humans or less giving them income, this feels so short sighted because I (if I were the state and I think everyone will agree after the cost analysis) would much rather pay a few hundred thousand dollars to even a few million$ right now to save 75-130 Million$ (on the smallest scale mind you, it can get exponentially more expensive)

I am not exactly sure how we can detect the rate of deaths due to LLM use itself (the 1 number) but I took the most conservative number.

And that is also the fact that we won't know if LLM's might save a life but I am 99.9% sure that might not be the case and once again it wouldn't be verifiable itself so we are shooting things in the dark

And we can have a much more sensitive job with better context (you know what you are working at and you know how valuable it is/can save lives and everything) whereas no amount of words can convey that danger to LLM's

To put it simply, the LLM might not know the difference between this life or death situation machine's code at times or a sloppy website created by it.

I just don't think its worth it especially in this context at all even a single % of LLM code might not be worth it here.

Maybe I'm unique in this experience, but the "actually more relevant to me" part is just never true. Most of the ads I see that are delivered via these auctions are just garbage or scams or "relevant" in a tenuous pointless way.

The only really relevant ads I've seen are from blogs that literally just sell ad space to brands and the ad is just a simple image link you can click on. Philosophy blog? Philosophy book ad. High end men's clothing blog? High end men's clothing brand ad.

I wasn't talking about the performance of solar, only the demand for electricity.

Someone pointed out that the big problem with solar isn't how do we store daytime solar for nighttime use - this is easily solved with batteries. The real unsolved problem is how do we store summer solar for winter use.

Australia doesn't have this problem, not to the extent of other colder places, because we don't need a lot of heating in the winter.

Bike > walk == public transit > used EV > new EV > used ICE > new ICE

That's pretty much the order of "greenness" in personal transport.

New EVs will pay off their added carbon footprint in roughly 1 or 2 years in most locations. The ultimate determining factor of how fast that is the energy mix of your local power generation.

The only time it'd probably be better to continue using an ICE is if that ICE is a moped or you live in West Virginia and drive a hybrid. For pretty much all other vehicle choices, switching to an EV will be greener.

> Nuclear can be curtailed

I know, that's why I said it's basically never done. And it's usually not even done even if the price is zero or below, because a lot of nuclear power plants have fixed prices that are guaranteed by the government. Also, operating costs of nuclear power plants stay the same even if you curtail it 100%, so it's more economical to curtail something else.

The METR study referenced (but not linked) in that paragraph has a breakdown of time spent https://arxiv.org/pdf/2507.09089 in figure 19 on page 33 which contradicts the description in the Register article. Open-source developers participating in the study who were randomly assigned to be allowed to use AI to work on an issue in their repo only spent insignificantly longer testing and debugging, but did spend much longer reviewing AI output, prompting AI, waiting for AI and "idle / overhead." In particular, time spent prompting AI alone was longer than the reduction in active coding.

Lessons for personal productivity include avoiding situations where you're blocked waiting for your tools https://xkcd.com/303/ , not using AI for tasks that you can implement in code as quickly as you can describe them in natural language, and on the meta-level using external randomness to decide between different approaches for the same task and measuring how long it takes you, rather than relying on your gut feeling how easy it was.

To add to this, almost nobody statistically keeps their vehicle very long. People keeping a car for 20-30 years is extremely rare.

The median length of car ownership is something like 7 years. Even if you are switching between used cars, most people are switching vehicles at some point.

From what I understand even considering battery mining and using dirty electrical generation, you’re still at breakeven within a couple years of driving with an EV.

Yeah lithium mining is bad, but don’t forget that oil is also extracted and “mine.” And your gas car uses a LOT of it.

I wouldn’t think too much about then average new car cost of $50k. That average is skewed by:

1. Expensive new car purchases (average != median)

2. Lower income people don’t buy new cars at all.

Still, some of the best new car deals are EVs because dealers can’t get rid of them due to the sudden expiration of federal incentives. Plus the used ones depreciate like crazy despite having better maintenance and lower miles. The lease deals you might get on an Ioniq are insane, good luck getting a gas car lease with that kind of value.

Let’s also not forget that the majority of housing units in the USA are single family homes where charging at home is likely to be an option.

Yes, he's certainly one of the worst villains in history already. Maybe not if you're Chinese, he's certainly a hero then. But if you believe in Western civilisation, then he is one of the worst in human history for sure. If you hate Western civilisation then you're right he was great.

> Also, assuming you know who I voted for is equally silly.

Yes, there we go, nobody voted for Trump ;)

"Biden was just as bad as Trump"

"Trump is just being honest"

"Trump is evil yes but so are all politicians but at least Trump is honest"

are basically brain dead takes from people to dishonest to admit they are basically OK with Trump. It's not true that Trump is the same as the rest. He is obviously worse than previous leaders.

Yeah I'm really watching less and less. I already closed all my streaming accounts after the fragmentation but a friend gave me access to his massive Plex library with all the latest stuff.

However I find I just don't care anymore. It's such terrible crap. And all the same tired old tropes. The snarky detective breaking all the rules. The muscly ex-soldier that bashes heads in. The superspies with offices that look like nightclubs. And spinoff after spinoff which are even more dumb and one-dimensional than the original.

Once in a while there's a pearl but they're few and far between. Most of it is fast food entertainment and utterly hollow.

I made an email mailbox using S3 object versioning.

Every email address was an s3 object so every new email sent to that email address was saved as a new object version.

Presenting that email as an mailbox was just a matter of reading all the versions of that object.

It worked!

I used this contraption as a domain level catch—all inbox for a while until cloudflare started supporting email forwarding.

I don't think it is dispositive, just that it likely didn't copy the proof we know was in the training set.

A) It is still possible a proof from someone else with a similar method was in the training set.

B) something similar to erdos's proof was in the training set for a different problem and had a similar alternate solution to chatgpt, and was also in the training set, which would be more impressive than A)

> Only the relatively tiny homeless population is poor by historic standards.

The cost to participate in society is much greater.

Yeah we do have more cars. But you also need to buy one to go to work.

We have education, but you need 22 years to be employable.

It’s probably not with continuing the discussion if you don’t believe poverty exists as a concept.

arm has toxic IP locks.

Everybody sane will want to move away from them, there is nothing chinese specific.

The most performant RISC-V implementations are from the US if I am not too mistaken.

Wonder if that hardware can handle an AMD 9070 XT (resizable bar). If so, we need the steam client to be recompiled for RISC-V and some games... if this RISC-V implementation is performant enough (I wish we would have trashed ELF before...)

Interesting. I like your body builder example, but I believe it more accurately describes the top seven fluff stocks. Valuation matters and just cause the stock is growing (according to estimates) doesn’t mean it’s worth buying. There are other factors like dividend yield and actually making real physical products that people really want, instead of a circular market dominated by a few players that essentially buy and sell products to each other using debt and rounds of vc capital that is constantly hyped up by media darlings.

As a point of comparison, the Radxa Orion O6 shipped a year ago as a 12 core ARMv9 board on same form factor and TDP, for $100 less, with 5x the single core performance (and including a competent iGPU, NPU and VPU). These are very much developer/tinkerer only boards as is.

Hopefully, in coming years, we will see more practically designed EVs that are more affordable. A practical car doesn't need neck-snapping acceleration, every bell-and-whistle and room for a family of six with a dog. I'd like to believe that as batteries cost drop, the incentive to justify the extra cost will drop. Then we can get back to "just basic transportation" rather than a luxury product for the rich. While $31k isn't exactly cheap, the base new Leaf is heading the right direction.

Why is 70% a end of life threshold? Considering that most major models are sold with configurations where the entry level begins under 70% compared to the "Long Range" model, clearly 70% is a perfectly fine level of battery for some users.

I myself have a 11 year old Nissan Leaf with pretty significant battery degradation (the guessometer says 70 mi range but I wouldn't count on more than 35-40) and it's fine for probably 95% of my driving.

If I were to buy an electric car with 300-350 miles of range today, I could easily see myself finding a ton of value in it in 20 or even 30 years. It's still more range than my current one! Lol.

This is an awesome effort. I stared and played with the rotating graphics at the top for a while before reading the rest of the article, trying to figure out why it was so much better than a lot of the efforts I'd seen before, and I kind of figured out what you must be doing, but I'll admit, I wouldn't have ever done it as well or put in as much work as you had - really excellent techniques for determining character!

I am actually really curious how performant this is and whether something like this would be able to contribute beyond just demo displays. It's obviously beautiful and a marvel of work, but it seems like there should be a way to use it for more.

Also, I did find myself wondering about the inevitable Doom engine

Really nice job!

> "Europe could probably defeat the US in a war"

USA's military budget is much higher than the sum of all other nations military budgets while it includes only 5% of world's population.

Roughly near $900 Billions versus $500 Billions Dollars in 2023.

Show HN: 21st.fund, an AI tool to discover grants and non-dilutive funding
by udit_50 | 2026-01-18 14:14:19+00:00
I built this after struggling to find relevant grants and fellowships myself.

The project started at the EF Hackathon as a credit underwriting and matching agent for founders. After speaking with founders and students, it became clear that discovery itself was the bigger problem. Most people do not know what grants or non-dilutive options exist for them.

So I iterated and built 21st.fund.

You describe who you are and what you are building, and the tool surfaces relevant grants, fellowships, and programs. The goal is to reduce time spent digging through scattered government sites, PDFs, and outdated blog posts.

The site is live at [https://21st.fund](https://21st.fund)

It is early and incomplete, but already usable. I am especially interested in feedback on:

* Result quality and relevance
* Missing grant sources or geographies
* Whether this is useful before paying consultants or advisors

Happy to answer technical or product questions in the comments.

As a non-American, even the US Democratic party is waaaay to the right of my Overton Window. While the US is arguing about if the 2nd Amendment should be restricted in cases like "fully automatic weapons" or "people with felony convictions" etc., I'm from a nation where the police aren't routinely armed and don't want to be, not even with pistols.

This doesn't mean I can't admire NASA, that I have to dismiss the Hoover Dam, that I think every act by Obama or Bush was heinous.

Likewise, I can look at Falcon 9/Heavy, at the progress with Starship, and applaud.

But.

His "Paint is Black" video, and what he claimed about it, was a lie. He himself is pretty awful, and already fits amongst the others you list given the revealed preferences shown by Grok, and by his reactions to criticism of Grok's behaviour.

The bonus-target market-cap of 8 trillion only makes sense with a very optimistic view of the AI Tesla's developing for both FSD and Optimus, and by "very optimistic" I mean "FSD turns them into a monopoly supplier of cars worldwide; or both FSD and Optimus together displace a significant fraction of the US low-skill jobs market while also getting a monopoly on industrial robots and a monopoly on cars in just the USA". It's the kind of thing I expect we'll be putting into history lessons next to Enron and Dutch Tulips, with laws passed to prevent whatever investigators find out to be the key mechanism behind it.

Even with SpaceX, it's impressive, but not because it actually hits Musk's goals, rather because everyone else in space is "over optimistic" about their schedules even harder than Telsa is.

GM HN!

When X announced they're giving $1M to the top article yesterday, I had a
thought: how do you even find these articles?

For anyone unfamiliar, X launched "Articles" on 2024 — long-form posts that
live outside the regular tweet stream. Think of it as Substack meets Twitter.
Some of the best writing on tech, business, and crypto now lives there.

The problem: X has no dedicated API endpoint for Articles. There's no way to:
- Get all articles
- Filter by topic
- Search across content
- See what's trending

You only discover articles by randomly scrolling through your timeline and
happening to catch them when they're posted.

The naive approach would be: use api to get everything, filter for articles. It's going
to be super expensive and impractical.

Then I realized something: Articles aren't posted by everyone. They're posted
by a relatively small set of verified accounts — founders, VCs, researchers, writers.
People who consistently produce long-form content.

So the solution became:

1. Curate lists of these high-value accounts
2. Use X's Lists API (which has much friendlier rate limits)
3. Poll every few minutes for new tweets from these lists
4. Detect when a tweet is actually an Article
5. Store it, summarize it with AI, make it searchable

The result is xarticle.news — you can search, browse by category, read
a blurb, comment or save articles for later.

To be honest, I made this website a few months earliear, but it was kinda expensive because
I didn't find a proper solution for the cronjobs, but I recently solved it and then I saw
the $1M prize and realized that it might be a good time to give it a go!

Would love to have some feedback from HN!

What is a "high-dimensional room"? A "room" is by definition three-dimensional in so far as we're using metaphor for description. Then to add this "high-dimensional" modifier does little for me, since the only visualizable high-dimensional cube is a tesseract, which still leaves you at 4-d.

The presented counterpoint to this metaphor has the "room" change into a "landscape". The room is a "flat void" compared to a landscape with "hills, valleys, and paths". None of these landscape features evoke higher dimensionality in my imagination. Certainly not in the way, say, the metaphor of the "coastline" of Great Britain does when discussing the unusual properties of a fractal.

These moves don't shift my railroad mind from one track onto another. So I wonder, if a metaphoric usage is not in some way universal, how can it be instructive?

Sure, but it's not that lucky. You can't set your house on fire by adding more and more roof insulation, it's the same here. The greenhouse effect saturates, it's not linear https://www.scirp.org/pdf/acs2024144_44701276.pdf There's also lots of feedback loops. CO2 levels were much higher in the past but life thrived, it wasn't waterworld, it was just a lot greener. So it only sounds lucky because climatologists have claimed even very tiny changes can cause a crisis.

Remember, we're talking here about a gas that makes up 0.04% of the atmosphere. Water is a much more powerful greenhouse gas. CO2 wasn't measured directly before about 1960, but if you believe the ice core measurements it was about 0.02% in 1850. It would be a very fragile planet that could be tipped into disaster by a change of 0.02 percentage points in the level of a single gas.
Show HN: Daily-web: your daily-updates web feed
by darkstarsys | 2026-01-18 14:16:37+00:00
My morning routine for the last few years has been to open my 54 "Daily"-bookmarked sites in Chrome and click through them all. That's how I avoid scrolling the rest of the time. But many of those sites don't update daily, so I just click quickly through those, scanning for changes. So why not write a script to do that? That's `daily-web`. Easy install, zero config -- just import from a folder of your Chrome bookmarks. Then run it to open a new window with the changed sites. (Full disclosure: vibe-coded with Claude Opus 4.5 in an hour, while I ate breakfast. The era of bespoke personalized software is upon us.)

The problem is that a sufficient black box description of a system is way more elaborate then the white box description of the system or even a rigorous description of all acceptable white boxes (a proof). Unit tests contain enough information to distinguish an almost correct system from a more correct one, but there is way more information needed to even arrive at the almost correct system. Also even the knowledge which traits likely separate an almost correct one from the correct one likely requires a lot of white box knowledge.

Unit tests are the correct tool, because going from an almost correct one to a correct one is hard, because it implies the failure rate to be zero and the lower you go the harder it is to reduce the failure rate any further. But when your constraint is not infinitesimal small failure rate, but reaching expressiveness fast, then a naive implementation or a mathematical model are a much denser representation of the information, and thus easier to generate. In practical terms, it is much easier to encode the slightly incorrect preconception you have in your mind, then try to enumerate all the cases in which a statistically generated system might deviate from the preconception you already had in your head.

Oftentimes, broadly accessible services are lower quality than more personalized ones, to the consumer.

As an example in US government bureaucracy, government software teams digitizing forms at one point weren’t allowed to utilize features like autofill or automatically filling fields based on previous answers because it would relatively disadvantage users using paper forms.

Government capabilities do need to serve everyone, and from the perspective of the whole society that is beneficial, but they are often are of low quality to the individual consuming them for this very reason.

Let’s exclude taxes, because obviously many people would hate them under any circumstances. Does the government do a good job providing the other services people interact with regularly? Do people love their visits ti the DMV? Are they satisfied with their interactions with the police? Heck, in my town, just renewing a dog license is a pain.

Those must be US estimates involving huge mileage, because - taking your existing ICE car's production emissions as an already sunk cost - replacing an existing ICE with a new EV would over a decade of driving the average EU mileage (~10k km) before reaching emissions parity.

It takes 2-4 years of that mileage alone for a new EV to reach lifetime emissions parity with a new ICE in the EU (which I know is longer than the US due to the vast differences in average emissions per vehicle between the two continents).

For most of the world, the GP is correct. Driving whatever car you have will always be more environmentally friendly than buying a new EV. Reduce and reuse are environmental cornerstones for a reason.
