My parents bought a Lexus that happens to be tall-ish with very bright headlights. I don't think I have ever driven it at night without people flashing me.

It's really up to regulators to put something in place though, I don't understand why it is taking so long. It's not like they want those super-bright headlights, they just come with the car...

But this is the neurodivergent ‘just world’ blind spot.

The world isn’t just. People like people with good genetics, because being friendly with the strong gets you benefits more than it gets you costs. Especially if you’re able to influence (or even pathologically manipulate) them.

Most people just know this, subconsciously. So they would probably even deny it. But it’s transparently easy to test, and even easier to see evidence of by just looking around.

Also, most attractive people work to be attractive because it’s often mutually beneficial (assuming they can counter manipulate or influence appropriately). Having people attracted to you gives you the ability to use other people’s resources for your benefit.

Most attractive people just know this, subconsciously. So they would probably even deny it. But it’s transparently easy to test, and even easier to see evidence of by just looking around.

This is generally kept covert, because like most covert power, it attracts negative attention if brought to conscious awareness - as then it’s perceived as manipulation, not influence, or encourages more jealousy, etc. as it’s not fair.

But life isn’t fair, except where we make it, and making something fair requires power.

And acquiring and maintaining power is fundamentally unfair.

>a valid security strategy

Here's your confusion: personal sites don't need a valid security strategy. They don't need nine nines uptime. They don't need CDN, and ability to deploy, etc, etc. That's all (and forgive the origins of the expression but it is the most accurate description) cargo culting. There's no issue if they're down for a couple days. Laugh it off.

Whereas if you put your site behind a defaults of a cloudflare denial of service wall then real human people won't be able to access your site for as long as you use cloudflare. That's much longer and many more actual humans blocked than any DDoS from some script kiddie. Cloudflare is the ultimate denial of service to everyone that doesn't use Chrome or some other corporate browser.

And forget about hosting feeds on your website if you're behind cloudflare. CF doesn't allow feed readers because they're not bleeding edge JS virtual machines.

> ChatGPT's moat is their name and user habit. People who are using it will keep using it. All/most of the products are _good enough_ for the people who already got used to using them, that they arent exploring competitors.

They have a long way to go to become profitable though. Those users will get less sticky when openAI starts upping their pricing/putting ads everywhere/making the product worse to save money/all of the above.

In a world full of (as noted) egotistical maniacs, is not what you are preaching surefire suicide?

Notably, neurotypicals generally fundamentally know this and even priests will throw abusive assholes out of church while still preaching peace, love and tolerance - without blinking at the apparent hypocrisy.

Or, as the case may be sometimes, initiating religious wars.

It seems like neurodivergents are the ones who get hung up on the literalness.

All life requires a degree of self defense/an immune system, or it dies.

And one could argue that the big reason we don’t have slavery anymore (by and large) is because of mechanization.

There were plenty of preachers in the US South (and plenty of religious figures everywhere in history) that preached the righteousness of slavery. While also preaching peace and love. And they put up quite a fight!

It was not an easy thing winning the Civil war, and plenty of wars were won on the back of slaves, at least in antiquity.

The Spartans weren’t feared because of their egalitarian and humanistic ethos, that’s for sure.

No they’re not.

String can be interned in Ruby, but it’s always possible for an equal string that is not interned to also exist. Hence interned strings can’t benefit from the same optimization than symbols.

You can first compare them by pointer, but on a mismatch you have to fallback to comparing content. Same for the hashcode, you have to hash the content.

I agree. He has scolded me before though, for submitting code he didn't like the look of. Felt a tad harsh at the time, that's the kind of thing that puts people off contributing. However, he's a better programmer than me so if he didn't like it he's probably right. Could improve his bedside manner a bit though. I'm sure others have said that about me too, perhaps I'm a hypocrite.

Regardless of that, anyone who doesn't discriminate against others for their politics would be an improvement.

Edit: a improvement on the other westerners in the core team who might be touted as the next benevolent dictator, as I doubt that benevolence would maintain.

@jerf beat me to it but indeed Golang is one of the very slowest compiled languages out there. I have an okay idea why but I wish someone there made a more serious effort to accelerate it at least by a factor of 2x.

I hate having to mull over the pros and cons of Rust for the 89th time when I know that if I make a service in Golang I'll be called in 3 months to optimise it. But multiple times now I have swallowed the higher complexity and initial slow building curve of Rust just so I don't have to go debug the mess that a few juniors left while trying to be clever in a Golang codebase.

Palantir is along with SpaceX, Anduril, and a few others some of the most important companies in America. They are the ones that are pushing America forward. Not selling ads. But upsetting the incumbents that are undermining the DoD and national security, and making real technical progress. These are the companies that if it comes to war are going to be pushing us forward.

If you're an event organizer whose big event is in two days, for example, then every minute your website's down translates to people not paying to attend your paid event. Bonus points because as event managers know, people often wait until 2 days before the event to subscribe for good. Bonus points if you knew this and therefore ran a costly email campaign just before the outage, a campaign that is now sitting at a near-0% click rate.

Don't ask me how I know.
Show HN: Browser-based interactive 3D Three-Body problem simulator
by jgchaos | 2025-11-18 15:00:36+00:00
Features include:

- Several preset periodic orbits: the classic Figure-8, plus newly discovered 3D solutions from Li and Liao's recent database of 10,000+ orbits (https://arxiv.org/html/2508.08568v1) - Full 3D camera controls (rotate/pan/zoom) with body-following mode - Force and velocity vector visualization - Timeline scrubbing to explore the full orbital period

The 3D presets are particularly interesting. Try "O₂(1.2)" or "Piano O₆(0.6)" from the Load Presets menu to see configurations where bodies weave in and out of the orbital plane. Most browser simulators I've seen have been 2D.

Built with Three.js. Open to suggestions for additional presets or features!

Great questions. It's targeted at dev teams wanting to build their own custom experiences on the frontend without having to deal with the complications of a scheduling backend. This could be anything from calendar functionality in their application to a platform that handles bookings for an office, etc. While assisting several startups get their product built, we ran into a need for something like this which drove us to build this as a standalone service. Figured others might find it useful as well!

I find this problem to be most severe as a pedestrian - when my eyes have adjusted to the darkness (even if I'm carrying a flashlight, it pales in comparison) and a modern car is oncoming, I cannot see _anything_. Out here in the sticks where there are no sidewalks I can either take it on blind faith that the driver has seen and will avoid me, or I can step way off into the ditch (but not everyone has that option).
by Aachen | 2025-11-18 15:02:25+00:00
We had a rental like that in 2023. The person who was driving was amazed and you could see the effect very well where it would light up the forest or town except for the one strip where this other car was coming on

(I'll say it looked cool even if we didn't need the gimmick, other drivers did occasionally flash us when they were at the edge of its detection range, and I can't imagine it improves the wildlife situation that's already not exactly thriving with habitat areas cut up by roads and light pollution from towns and cars everywhere around it)

I haven't seen this type of headlight as a third party yet. I've been on the lookout for where another car might light up areas around me but never noticed it. Not sure it's that common in Germany or the Netherlands
by catlikesshrimp | 2025-11-18 15:02:38+00:00
We needed some brighter lights before the current craze.

When you aren't using strong lights your pupils open more. Now we need much brighter lights than traditionam because the lights from other cars leave you blind for too long.

Context: I live in 3rd world country with non lit interurban roads. People must to walk and ride bicycles, only they do irresponsibly without anything reflective, maybe only with their cellphone screens lit because they are using it. I sometimes reduce speed to 30 km/h when a car comes from the opposite direction.
by iso1631 | 2025-11-18 15:03:07+00:00
In the country you need decent lights on the road to spot the potholes, animals, and people. And of course you get pedestrian traffic, especially at this time of year when people are walking dogs after getting home from work.

The problem isn't as much bright lights though, it's lights shining in your face.

1) "auto dipping" headlights don't detect oncoming traffic

2) "matrix" headlights don't detect oncoming traffic

3) Headlights are adjusted to point as high as possible, on cars with ridiculous high headlights, so although they are pointing "down" (just), they are pointing into your car

4) My 2005 car's headlights are yellow. Modern ones are white. If I drive with full beam on, I don't even get flashed. Yellow isn't as dazzling.

Of course it's all rather meaningless, nobody chose brighter lights

?? It's free, and it protects you from all sorts of nasty things.

I can't think of any reason not to use cloudflare. It's _dead easy_ to set up too.

I can't help but think that the author understands what cloudflare actually does, or just has a poor understanding of what goes on on the internet. Probably a bit of just being in a bad mood about cloudflare being down too.
Ask HN: Advice for getting into post-training / fine-tuning of LLMs?
by hedgehog0 | 2025-11-18 15:04:00+00:00
Hi everyone,

Those who follow fine-tunes of LLMs may know that there’s a company called Nous Research has been releasing a series of fine-tuned models called the Hermes, which seem to have great performance.

Since post-training is relatively cheaper than pre-training, “so” I also want to get into post-training and fine-tuning. Given that I'm GPU poor, with only a M4 MBP and some Tinker credits, so I was wondering if you have any advice and/or recommendations for getting into post-training? For instance, do you think this book https://www.manning.com/books/the-rlhf-book is a good place to start? If not, what’s your other recommendations?

I’m also currently reading “Hands-on LLM” and “Build a LLM from scratch” if that helps.

Many thanks for your time!
by ptx | 2025-11-18 15:04:21+00:00
I imagine the statement is unpopular because it's deceptive and conflates different kinds of trust. If we (data subjects under the GDPR) voluntarily consent to have our data processed by them (the data controller), then we trust that they will process our data in a responsible way. But when we trust them with root, we trust that they will not take our data to begin with, because doing so would be unethical, unacceptable and (without proper consent and basis for processing) illegal.

That said, I agree that Microsoft can't really be trusted with anything.
by kragen | 2025-11-18 15:04:38+00:00
Yes, all of that is correct as far as it goes, and isn't in contradiction with what I said. You'll notice that the EPA page you linked https://www.epa.gov/hw/end-life-solar-panels-regulations-and... is mostly about an effort to reclassify solar panels as non-hazardous waste, which is specifically because of what I said. See for example https://www.sciencedirect.com/science/article/pii/S030147972... "About 8% of traditional PV samples exceed the 5 mg/L limit for Pb in TCLP tests. No modern PV samples exceed the 5 mg/L limit for Pb in TCLP tests."

But TCLP is already an extremely rigorous test, far worse than nearly all actual landfills, intentionally. It uses acetic acid, one of the very few acids that forms a soluble salt of lead, and none of the anions present in normal soils that normally immobilize lead, such as carbonate, phosphate, sulfate (!), and chloride.

And air pollution from pyrometallurgical recycling of the kilogram quantities of lead from car batteries is totally irrelevant to the safe containment of the milligram quantities of lead from (probably hydrometallurgical) recycling of solar panels. I am really struggling to imagine how your understanding of the issue could be so shallow that you thought it might be relevant.

Scrap lead is like US$1/kg. Nobody is going to recycle solar panels for that.

I'm the one who's flashing you. I'm flashing you because your headlights are bothering me. Showing me that you can bother me even more does not make it better.

Still, obviously, nothing you can do, or the driver in general. And I guess the manufacturers aren't incentivised. Regulation is the only thing that I can think of that will work.

I remember light used to be much paler and became brighter around the 2010. just go drive in an old car (20+ years) and a new car.

You are right also especially that there is a good side to it: in countryside roads you will able to see pedestrians/bicycles that don't use refractory lights better. Surely you are blinding everyone else.

I've learned this the hard way, by putting an Arweave gateway behind Cloudflare.

The gateway was checked regularly for random data and the client would stop a download after 1MB, causing the gateway to stop sending the rest of the file.

However, Cloudflare CDN wouldn't stop when the client stop, causing the gateway to send the whole file. Some files are multiple GBs big, so I suddenly got an invoice of 600€.

Just because this is YC, I thought I should pitch in -

A high-trust society that solved coordination problems through legislation, could solve this with a win-win technofix solution where everybody's headlights are as bright as the sun and nobody suffers ill effects.

That technofix solution is polarized headlights, and right-angle-polarized night driving glasses or windshield tints.

> then your host taking your website down and then you having to run circles around their support staff to bring back the website up again

These are very different situations. With a DDoS the disruption ends when the attack ends, and your site should become available without any intervention. Your host taking down your site is a whole different matter, you have to take action to have this fixed, waiting around won't cut it.

What did the kidnappers demand?

I find it odd the amount of families kidnapping their own family members lately, as that's typically the only time demands aren't made by kidnappers.

Don't think that would make them a Nazi though. Not to say there aren't any, but in modern times they're located in Ukraine. Azov Batallion has videos posted where they have whole stadiums filled with them doing their chant? which is disturbing.

Either way stay strong.

They'll call if they haven't yet.

This is what a lot of people get wrong. Money doesn’t have to have liabilities, only fiat currencies do. Commodity money eg gold or silver are valuable in and of themselves, for instance. The government sues signiorage there.

However, individual liabilities are a great way to introduce currencies into circulation. Start with eg loyalty points at a restaurant or credits redeemable aboard a ship etc. We are working on that: https://community.intercoin.app/t/local-community-currencies...

A city can skip all that and just issue a UBI to all its citizens in its own currency, and start accepting taxes and fees in that currency. Read this: https://community.intercoin.app/t/rolling-out-voluntary-basi...

Shameless plug: Some of my hobby projects written in C (e.g. https://github.com/pts/bakefat) can be built reproducibly for Linux >=1.0 (1994), FreeBSD (same ELF executable program file as for Linux) and Win32 working on all versions of Windows (Windows NT 3.1 (1993)--Windows 11). The C compiler (running on Linux i386 and amd64 host) used for the release build is self-contained and included in the project, along with the libc.

Doing such backward compatibility is definitiely possible for command-line tools. Once set up, it's automatic, and it needs extra testing after major changes.
by glenstein | 2025-11-18 15:06:26+00:00
Exactly. It's also just bizarre to attempt to make the whole conversation about special one-off cases where some regions already have so much solar power that they won't benefit from adding more when such cases are not representative of the global picture, which is that there's abundant need going forward and abundant capability to build it out going forward.

So why focus on the unrepresentative cases, unless the intent is to be misleading? There'd better be a very good insight at the end of this road that's worth price of "accidentally" of invoking unrepresentative examples, and it better be something a hell of a lot more substantive than going "gosh renewables, gee, I don't know. Denmark sure has a lot of renewables already, don't forget about that! " It's the "You Forgot Poland" of energy debates.

If you don't like the Apple device, use something else. It's not like a messaging platform where you'd need compatibility with other peoples' phones.

If you'd bothered to dig into the spec, v1.0 basically says do what you want. v1.1 defines a proper namespace and well known descriptions for multiple batteries. Apple did well to avoid the interoperability minefield.

Hey, s1mplicissimus, hope you are well!

Dud(ett)e, it's a message board comment, not a scientific study.

But do you really doubt that most ISPs will gladly disable your 1Gb/s home-slash-SMB connection for the rest of the month in face of an incoming 1Tb/s DDOS? Sure, they'll refund your €29,95, but... that's about it, and you should probably be happy they don't disconnect you permanently?

People here, and in tech in general, are so lost in the sauce.

According to at least OpenAI, who probably produces the most tokens (if we don't count google AI overviews and other unrequested AI bolt-ons) out of all the labs, programming tokens account for ~4% of total generations.

That's nothing. The returns will come from everyone and their grandma paying $30-100/mo to use the services, just like everyone pays for a cell phone and electricity.

Don't be fooled, we are still in the "Open hands" start-up business phase of LLMs. The "enshitification" will follow.

So your argument is that an intelligent, erudite black Jew is siding with white supremacists against people of color?

Yesterday I spent two hours looking for something that I thought I needed. Ten minutes in I thought of an alternative solution that wouldn’t require the item I was looking for. I wanted to do more interesting things, but I still /had/ to find it. I’d accidentally end up doing it again when I try to stop. A friend who was observing this tricked me into eating something, and then I was able to stop.

If I forget a word mid conversation, I spend a lot of time trying to remember it. I can google or ask the chat bot, but emotionally I want to get there it on my own.

I think that I’m addicted to the feeling I get when I find these things or solve a very difficult problem. After reading an earlier article about “aha” moments, I wonder if it’s the same circuit. Maybe there is also a natural predisposition for hunting in my brain, which is why food seems to help me get past these … moments.

This is tangential but one thing that bothers me about C# is that you can declare a `readonly struct` but not a `readonly class`. You can also declare an `in` param to specify a passed-in `struct` can’t be mutated but again there’s nothing for `class`.

It may be beside the point. In my experience, the best developers in corporate environments care about things like this but for the masses it’s mutable code and global state all the way down. Delivering features quickly with poor practices is often easier to reward than late but robust projects.

> This is exactly what high beams are for,

Judging from comments in this thread, large numbers of people are suggesting that they are actually entitled to blind others because toggling back and forth is an inconvenience for them, and/or the "smart" cars that are auto-toggling high beams have left many drivers completely ignorant that toggling is actually possible.

Related question, are cars that have completely removed manually controlling high beams actually street legal?

The lack of equity building for such a long time in a 50 year mortgage would seem to make the potential for being "underwater" (owing more than your home is worth) ... highly likely.

A lot of the fixes for that in the pros is "well people will refinance and make good decisions". I'm not sure we've seen that as a sure thing in the mortgage world. I sort of recall a time when we saw lots of bad choices....

This seems like an economic time bomb.

Absolutely solid point; there are a couple of apps I use daily for productivity, chores, even for alarm scheduling, that with the free versions, the ads wouldn’t load so I couldn’t use them but some of them were updated already. Made me realize I forgot that we’re kind of like cyborgs relying on technology that’s integrated so deeply into our lives that all it takes is an EMP blast like a monopolistic service going down to bring -us- down until we take a breath and learn how to walk again. Wild time.
