This is my honest assessment of the calculus of the move. Please don't interpret any of this as me personally supporting or approving of these motives. I'm just trying to have a genuine intellectual discussion about the potential thought processes of our collective leaders.

* Quick, victorious wars can be incredibly popular domestically, regardless of whether surveys say that only 16% of the US population supports the war. Trump needs an approval ratings boost. The global tariff shock was a PR disaster. A quick, victorious war is a tried-and-true approval rating booster over the last 200-300 years. The key, of course, is actually keeping the war truly short and victorious. If it drags on, or if people start asking "have we truly won?", then that's a whole different matter.

* We have moved out of a unipolar geopolitical world and into a multipolar one. The USA is checking the ambitions of the rival powers. Want to invade Ukraine? Sure, go ahead and try, but it will be a multi-year slog. Want to go for years maybe developing nuclear weapons, maybe not, and making US antagonism a central part of your political platform? Watch us systematically attack your nuclear program and and air power and do highly targeted assassinations of your political elites over the course of two weeks. Want to invade Taiwan? Look at what happened in Ukraine and Iran and maybe reset your expectations about how that will pan out.

* There has been a lot of questioning lately around whether the US will actually help their allies when they're in a pinch. This is sending a pretty strong message of reassurance to allies.

* Trump may actually want things to escalate to a point where he can reasonably declare martial law within the US. How do you stay in power when you've already hit your two-term constitutional limit?

Your question was "how does it benefit the US?" but I don't think that's answerable because everyone has a different take on what's best for the US. It's much more feasible to discuss "how does it benefit Trump?" or "how does it maintain US's position as a world power?"

>Sleeper trains are held back by flying getting subsidised heavily by not having kerosene taxed

Is whatever fuel trains use taxed? If not, I don't see how this is relevant.

>and national governments giving airports effectively unlimited room to grow

Which countries are those? For instance in UK they wanted to expand Heathrow since as early as 2006, yet due to various government shenanigans isn't due to complete until 2040, assuming it doesn't get backtracked again.

https://en.wikipedia.org/wiki/Expansion_of_Heathrow_Airport

Moreover since you're comparing against trains, don't trains need land as well, for the tracks and stations? Why do trains seemingly get a free pass from you on that?

>Trains in general are held back by governments not investing in rail infrastructure, because the pork barrel of another motorway link is so hard to resist (and we're not properly maintaining these either).

What makes motorways more of a "pork barrel" than train tracks?

Well, I'm not sure who forgot COVID, but elements of this are absolutely true.

I've been reading The Count of Monte Cristo—a 1200 pages unabridged, clothbound edition that will spend 40 pages of wandering setup just to deliver one striking image. It was a banger in it's time, and it's still a banger, but it's striking how much it asked of its readers. It will take me the rest of the year to finish.

And this is the thing, we really do live in a toxic attention ecosystem that rots our brains. Like the author, I've been trying to reassert control my own attention, and it's shockingly hard to do.

I'm not sure if I'll manage to make it work. But let's suppose I do: I've deleted all social media, deliberately set my relationship with news, if I feel the urge to post dump it in a paper notebook instead, and somehow achieve the miracle of getting slack to chill out...

... much like learning to cook is great for me but doesn't solve the social costs from widespread ultraprocessed diets and resulting metabolic disorders, getting my own attentive house in order does not change the global brainrot and toxic political incentives.

If anyone has found a way to turn that tide, I'm all ears.

Strong disagree. Education is key, as are not leaving children that are too young to be educated alone where a weapon (not just a gun) is.

Curiosity is the number one problem with kids and guns, and that's because we hide them behind a mystique and don't make them understand. But talk to any redneck kid, and guns aren't a big deal, because they've had the mystique removed through education and familiarity.

You cannot obtain regime change, nor end iran's nuclear capacity, without a ground invasion. Everyone involved knows this.

So either their state goals are lies, or their strategy is a losing one, or they anticipate a ground invasion.

Either way, the choice before israel/us is lose-lose.

But of course, it's imperative we take death threats very seriously, so just you know, err.. we.. err.. dont have to... err. dunno.

Of course that sentence should be, "it's imperative we pretend to take death threats seriously so that israel's ability to dominate the middle east through wars of aggression is maintained, even if that comes at the cost of the blood and treasure of the US"

More interestingly is the timeline. Broke ground in 2022, finished in 2025, and likely operational before the end of the year.

Now sure, it likely took some years in the planning as well, but it shows that infrastructure can be built in reasonable time lines when politics and nimbyism don't get in the way.

And this isn't a simple bit of construction- it spans a serious bit of active highway.

Uber couldn’t exist before a critical mass had a smartphone with GPS in their pocket. I don’t see what the bar is if we don’t consider it revolutionary. Anything that goes mainstream is going to eventually feel pedestrian and watered down from a tech perspective. But if you look at how most people lived and worked 30 years ago to today it’s a massive change.

> chicken livers are usually cheaper per amount of protein than most other kinds of meat

Any idea why? My layman guess is it’s a non-famous byproduct of chicken muscle, that people tends to consume more. Would removing the availability/demand (=make it more popular) reverse the price?

Thanks for the information about carotene > vitA, it resonates like the heme/non heme iron where the heme one is easier to get but can slip to too much, leading to more oxidation and then (in extreme case) concert (IIRC that’s one of the way too much read meat induce cancer risks). OTOH non heme iron (in cereals, peas, fruits, vegetables and milk) is directly used for catalysis and isn’t store, so one can’t get too much.

I’m a layman, don’t take what I said as authoritative. You’re welcome to point out if I’m wrong or add precision.

Social media users placed by iran's full missile defense systems? Social media users at the bottom of 100m of granite? Social media users amongst the iranian barracks?

I called the war for Russia ~2 years ago, just as the "counter offensive" by Ukraine was starting. Go back, if you wish, to that time in the news and find exactly what english-speaking western median, and social media, was saying.

What is the picture you get, of Ukraine and its counteroffensive, delivered to you from these sources?

It's always a little stunning just how easy it is for publics to be manipulated. Oh what a world.

Instead of adding friction, part of the work of oneself is about finding the root cause of why we go into those places and understand up to which point spending too much time on those is not only detrimental to society but to me personally. I mean, a doctor would tell me that « you have brain rot » would freak me so much that I would do anything to reverse or get rid of it asap. Idk, maybe after +20y of wasting time online I got that it’s a ressource I won’t ever get back and I resent wasting it too much now, which gets me off using all the links he blocked without efforts.
Show HN: M3ripple – React Library for Ripple Effect with Sparkles Like Android
by yuyake-litrain | 2025-06-22 14:47:20+00:00
Hi HN, nice to meet you — I'm yuyake-litrain.

I've always liked the Ripple Effect with sparkles that was introduced in Android 12. (Some people said it looked like a graphics bug, which is probably why it was toned down in later versions.)

When I saw Vuetify's beautifully crafted implementation of the Material 2 Ripple Effect, I thought it would be great if we could have something similar for Material 3 on the web as well. After a lot of trial and error, I’ve now created a React library that reproduces this effect.

I’ve also built a documentation site that mimics the look and feel of the Android settings screen.

I'd love to hear your thoughts — feedback, questions, suggestions, or anything else are all welcome!

(English is not my first language, so I rely on machine translation. Please forgive any awkward phrasing.)

> A community where every household does not have guns is safer than one that does

Except this isn't borne out in the data. Look at deeply conservative places where guns are literally everywhere, and you'll see very low crime rates compared to cities with strict gun control.

And why? Well, as a criminal, I'd be loathe to try something when there's a good chance the victim is armed.

In your perfect community scenario, a single armed criminal would wreak havoc, completely unopposed.

As far as I'm aware, the background of the 1953 coup was oil. The democratic government of Iran want to nationalize the oil industry, and western oil companies did like that. On top of that, Iran was willing to do business with the USSR. That's why US and UK secret services conspired with the ayatollahs to overthrow the democratic government and replace it with the shah.

No shit the result of 1979 is not what the Iranians wanted; there have been frequent democratic uprisings since then. Most Iranians didn't really care one way or the other about Israel, although you can't really blame them for not liking the US. And Israel has never really had an issue with Iran. But it's the ayatollahs who have been extremely hostile towards Israel, and have spent decades funding Hezbollah attacks against Israel.

I'm not going to defend Israel; they've committed plenty of crimes. And war crimes. But almost entirely against the Palestinians, not against Iran.

The Middle East is complex, and there's no simply good vs evil there, but the ayatollahs are definitely not on the side of good.

Yes, web apps all need logging, performance dashboard, redundancy, DB backups and such.

This could be a stack that could be parametrised with sound defaults just requiring some terraform provider credentials as well as a path to an executable web app and a choice of database engine.

I would not agree that the use of Galois Fields in Reed-Solomon code requires a background in Abstract Algebra. For what it's worth, decades ago, studying Galois Fields for Reed-Solomon code opened my eyes to the fact that you can create your own algebra... I'll never forget that "wow" moment. But being mathematically illiterate, I never found a reason to create my own algebra for any application. :)

>The rest of the world can do nothing about it. See: Soviet Union, China.

Of course it can. During the cold war, most US aligned countries had massive trade restrictions with the USSR. The fix is easy on paper: reduce trade with countries that break the rules. Of course, that's easier said than done, but it is doable and effective.

Imagine what can be achieved if Europe, Canada, UK, AUNZ, Korea, Japan, BRICS, would collectively put restrictions on the US whoever the US decides to fling its dick around the world stage. The problem is getting countries to cooperate so it's never gonna happen. Would make a cool novel though.

The police aren’t here to protect citizens, courts here have ruled on this. Police are an extension of corporate power & the wealthy. The LA Sheriff’s Department is filled with police gangs.

We’ve seen the footage of the police brutalizing peaceful protestors beating them with clubs, riding over them repeatedly with horses.

The police in this country are woefully undertrained compared to the rest of the industrialized nations.

Hi HN,

I built a multi-LLM chatbot as my first solo project. It's a simple PWA that lets you chat with different free models from Openrouter and keeps your conversation history even when you switch between them.

I was able to build this largely thanks to tools like Replit and Codex, which helped me bridge the gaps in my own coding abilities.

I posted it here last week and on other platforms, but it got almost no traction (2 upvotes, 0 comments). This has made me question what I'm missing.

I'm here to ask for your candid feedback. Is the app itself flawed in a way I'm not seeing? Is the idea fundamentally uninteresting, or is the space just too crowded?

I'd appreciate any insights you have. Feel free to be as direct as you need to be.

being able to use a telegram client for matrix would be great, but the problem with matrix is not so much the UI but the complex handling of encryption which can sometimes fail. unlike deltachat which downgrades on failure, which is bad, matrix stops working on failure, which for the average user is worse. a better UI won't fix that unfortunately.

still i like the idea. but deltachat also has a nice UI, and for matrix i use fluffychat which is also quite nice.

How could you ever prove that nobody is doing that? You can believe anything that way

One can't prove god doesn't exist either, but as someone who made some privacy-friendly front-ends, I tend to expect honest intentions. If you find one that suddenly asks for your login data or sets tracking cookie, sure, be wary, just as with any other site that asks for data they don't need (see: literally every cookie wall, because if they had good intentions, it would fall under one of the five other reasons to use personal data and they wouldn't need to fall back to asking for consent)

This doesn't seem to work at all for me, but I don't see any error messages in the console or anything... I just see a dark gray screen with an (i) on the top left (with the instructions), but nothing seems to have any effect (left or right clicking, using the scroll wheel or dragging the mouse with left or right click) don't seem to have any effect. The only effect I'm seeing is right clicking on the page shows a "[CLIENT TRIGGER] Right-click at (123.456, 789.012)" message in the console log.

I can see that there's some traffic (for example, I see some WSS on socket.io, and some XHR for /state, /clients, /checksum) but it doesn't seem to change anything on the screen.

> Suggesting all evangelicals want the world to end immediately is in the same vein, IMHO.

But here's the thing. That wasn't the suggestion. The bunch of links that he gave you don't suggest that.

At least my impression is that there are a considerable amount of Evangelicals that support whatever you think is going on in Israel under theological pretenses. Any notion of timing carried by his initial remark is likely attributed to this.

Maybe I'm misunderstanding the sum of the links handfuloflight shared. Maybe he should have done us the courtesy of spelling it out for us instead, as in, when you asked him:

> Do you believe all evangelicals believe the same thing, and that we want the end of the world to come immediately?

He should've answered the question straight up instead of (what I interpret as) responding to the emotional side of your comment:

> Where would you get such a strange idea? I can assure you it is an ignorant thought.

With an indirect explanation of his point through a bunch of links.

I get it, that's the responsible thing to do when the discourse is trying to present itself as something other than a flamewar, or something like that, which it might as well just be so we can all be more direct and upfront with what we think and feel instead of doing this half-bunned Socratic dialogue.

On the other hand, if someone tries to insult your intelligence in a sophomoric way it makes sense to leave them to their own devices and if they're so smart themselves they can read between the lines on their own.

Anyway, these are non-rhetorical, please-say-yes-or-no questions:

* Would it be fair for me to assume that you are an Evangelical who doesn't support whatever you think is going on in Israel under the theological pretenses that other Evangelicals are known for (i.e., the "apocalyptic accelerationism" handfuloflight refers to)?

* Would it be fair for me to assume that handfuloflight's remark was solid but fell short in the generalizing way that jokes often lay, because of the possibility that there are Evangelicals who don't support whatever you think is going on Israel under the theological pretenses that other Evangelical's are known for, because it has grave moral implications and indicative of the contemporary fractures that capture the faith at large?

If you're offended, then suck it up and be open about your vulnerabilities instead of goading the other party into an exchange that they're better suited than you at carrying on. Maybe they'll show you the empathy you desire, within reason.

The closer you move to the user, the more the threat of creepy buddy watching over metadata of people they know grows.

actually i don't follow that argument. it is more likely that my data gets caught up with someone accessing a larger server than my own server. if someone targets my own server they may as well target all my messaging clients and get all the data from there.

Can switches like this also detect usage, like current flowing? It might be a fun and healthy twist to plug a walking pad/treadmill into a smart plug and then either make it so brainrot websites are only viewable when the treadmill is being used or make a small app that tracks the time the treadmill is used and then only allows that amount of time on brainrot websites.

While the invention of stainless steel is one of the most important in history, it should be noted that almost never an invention appears really independently, but almost always it appears as a consequence of a chain of prior inventions, which have been necessary to make it possible.

Leading to stainless steel, a first step was the discovery of the method to produce aluminum cheaply, by electrolysis. With cheap aluminum available, a method for producing chromium was discovered, by reducing chromium compounds with metallic aluminum.

With metallic chromium easily available, after a century from its discovery, during which making metallic chromium had been impossible in great quantities, it has become possible to investigate the properties of the chromium alloys with the other available metals.

Soon, it has been discovered that chromium can produce interesting alloys with cobalt ("stellite") and with nickel, and that these alloys are the first metals that can rival the platinum-group metals in chemical resistance.

It has been suggested that these chromium alloys could be used for stainless cutlery, but the high prices of cobalt and nickel have prevented the use of such alloys, except for special applications where the cost was unimportant.

More than a decade later, the next logical step has been the discovery that the expensive cobalt and nickel can be substituted with cheap iron, without diminishing much the chemical resistance of the alloys.

It should also be noted that while Brearley has invented the ferritic stainless steel, which has only small amounts of any other elements besides iron and chromium, almost simultaneously a different kind of stainless steel has been invented in Germany, austenitic stainless steel, which also has significant amounts of nickel, besides iron and chromium, with enough nickel to change the crystal structure of the steel.

Austenitic stainless steels have various advantages, especially that they are much more suitable to cheap processing by plastic deformation, so nowadays they are much more widely used than the kind of stainless steel invented by Brearley.

Because investment to space stuff fell out of fashion at the end of the cold war, and because - unlike in better cultures - being a "nerd" has been culturally frowned upon for an all too important half a century, while being a borderline braindead jock was considered the epitome of human existence.

Where iron and heavy metals enter the picture remains a mystery to me though. Do you reckon the asian minority of America disproportionately manages to snatch most every academic award because they dodge them iron particles like Neo from Matrix or something? Or are they participating in some seriously secretive lead snorting competitions?

I sure wonder how to explain a totally made up scenario. Maybe that onus is on you? And why not reply to this comment if you have a reply prepared instead of editing your previous one?
