> Every CS student should know there's no free lunch in search and optimization

The no free lunch theorem is so absurdly limited because of the constraints that it's IMO a tautology and fundamentally irrelevant outside of exceptionally tiny areas. You can't have one search algorithm that's better than others on average when searching entirely random things with no structure? 1. Yes, obviously. Nice to have a formulation but it's not exactly a surprise and 2. That's not what we deal with in the real world.

I’ve been playing with HTMX lately and wanted nicer charts without wiring a bunch of frontend code, so I wrote a small extension that connects *HTMX + ECharts + SSE*.

It lets you:

- stream chart updates over *Server‑Sent Events* (no full re‑render)
- fetch static ECharts options once
- or periodically *poll* an endpoint with a simple `data-url="/api/chart poll:1s"` syntax

The extension handles creating/disposing ECharts instances, ResizeObserver, SSE connections, and polling timers. You just return standard ECharts option objects from your endpoints.

in repo you can find gif with demo, the repo itself is a demo, in README you can find examples in bun/nodejs, c#, python.

Core Data turns 21 this year — and it's not dead. But it's starting to feel like a visitor from another era. Concurrency wrapped in perform, model declarations buried in boilerplate, string-based predicates waiting to bite you at runtime. This article isn't telling you to leave. It's asking a harder question: if you're staying, what can actually be done?

I've got 3 hardware versions in my studio - ranked from best to worst for emulation: a T-8, a TD-3, and a TB-3. The TB-3 is rubbish, the T-8 is excellent, but I still most often reach for Pure Acid - it seems to have that variability in the filter that a real 303 has.

Repo: https://github.com/winaviation/liquid-web

I have been trying to make the Liquid Glass effects in the kube.io LG blog (https://kube.io/blog/liquid-glass-css-svg) usable with JS modules. The thing is, the performance is absolutely cooked on low-end or even med-end hardware if you use big sized Liquid Glass components.

Would love some feedback on how to make this actually usable for the average user without turning their device to a heater.

This I don't understand. DINsync is raw trigger outputs/inputs like you'd have in a modular synth, in contrast to MIDI that has to send serial messages over a 1k data bus.

Perhaps this take has something to do with calling a five-pin DIN plug '5-pole'? Something's wrong and backwards here.

Again, I guess this is where we are now? I remember reality, but here we are.

But you have to create more value than you consume. Which I have to imagine for a vast majority of the population even today. Consider how many goods and services are only accessible to the middle classes due to cheap available credit or subsidies. Without them, people on their own do not produce the value needed to have these things.

That is… unless the population was forced to accept steep declines in standard of living that would reduce their consumption effectively.

> Secondly, it should perhaps be a concern for Zig, now at 10 years old, to still produce solidly breaking code every half year.

Not at all, if the team needs 30 more years they should take it.

> However, the outlook for a Zig 1.0 is bleak from what I gather from Zig social forums: the most optimistic estimate I’ve heard is 2029 for 1.0.

Funny you see it as bleak when most of the community sees it as the most excitinh thing in systems programming happening right now.

I think you comment is in bad faith, all the big zig projects say that the upgrade path is never a main concern, just read HN comments here or on other zig threads, people ask about this a lot and maintains always answer.

> Imagine that we made an LLM out of all dolphin songs ever recorded, would such LLM ever reach human level intelligence? Obviously and intuitively the answer is NO.

Not so fast. People have built pretty amazing thought frameworks out of a few axioms, a few bits, or a few operations in a Turing machine. Dolphin songs are probably more than enough to encode the game of life. It's just how you look at it that makes it intelligence.

> I'm not entirely sure I buy this. Everything you said feels true, and it's happening in the moment. But I think you're missing the forest for the trees. The way you wrote "hyperfinancialisation" makes me think you are European (German?)

> I'd imagine a vision for the country would be explained at places like World Expo right? In 2025 their booth (developed during Biden years even though it launched during Trump) gave a "semi" okay idea of where the country is placing its vision. Was it expressed well at the Expo? Not entirely sure, but it was there.

A vision for the country is something that's built upon, across governments and party lines since it's "what the nation is about" more than what policies are being voted on by diverging ideologies, it's something to tether a nation's spirit onto. Advertising something on a World Expo is just advertisement, it's the actions over a longer period of time that can be linked to a vision that actualises it, and that's what I don't see from the USA at all.

> In the end, the underlying theme seems to be "optimistic collaboration led by American innovation". Yeah I know its hard to picture this in the moment after everything that has happened in the last year but as the Biden years ended this was the thinking among government officials.

That line couldn't reek more of corporate-speak than it does, it's something you'd read on a PowerPoint slide from McKinsey. It doesn't inspire anyone, reading it doesn't make you feel "yeah, I want to buy into that". It just cements more of my thought that the vision is "get wealthy", it just states an end without inspiring any of the means for it.

Also, the Biden years already feel long gone, it could've been the beginning of re-steering the ship into a brighter path, barely a bit more than a year without Biden and nothing from the previous USA is recognisable.

> Watching this video a year later, it just seems so comical that this whole vision of "collaborative innovation": of the future being a collaborative project, with America wanting to lead it but not alone, and the slogan 'Imagine what we could create together' just seems comical after everything that's occurred in the last year. I guess it remains to be seen if this vision will hold once Trump is out of office.

Exactly, it's comical that it was kept as a pitch given everything we are seeing from post-Trump USA. It's really hard for me to imagine coming back from this, even more if it does last for another 3 years.

Maybe the Asian countries can finally get together and hash out a way to deal with Israel. It seems like an insurmountable problem. The elites in the US either fall in line or when they try to push back they are eventually forced to relent(ex. Musk in the early Twitter days).

This entire saga has been a wake up call to the middle eastern states. They thought all the money they paid to the US over the years got them a first class ticket when in reality they are sitting way back in economy.

There aren't many options on the table. Cozy up to China? Maybe the middle eastern and OECD countries can do it but not the Asian countries. The right strategy would be to join forces to try and help the US get back on track because what other superpower is there? And that means somehow dealing with Israel as they are going to continue causing trouble for everyone.

If unspecified, 'exit' would mean 'exit right' to the right side of the traffic flow. In dense urban areas it might make sense for geography or cost reasons to put it on the left in which case youll see "Exit Left" to make sure people know to be in the 'fast lane' in preparation to leave the highway since it departs the highway exceptionally on the left

I-94 and I-35E in St. Paul, Minnesota comes to mind. You just merge left onto the other highway if you need to change.

I’m a parent. Girls 7 and 4. I think you’re right about a number of parent habits.

Hard to impose a device limit on a kid if that kid watches you use your device constantly. I’m not some hero here - constantly reminding myself to be aware.

Now, I think imposing limits in the open world is a specific challenge. To your point, you’ll see kids at restaurants on iPads. Well, now your kid wants iPad. You don’t give it? They start a shitstorm.

I don’t think an outright device ban is so critical. But limits are important, and even more important is sticking to what you said you would do as a parent. With mine, they sense that moment of giving and almost instinctually rush to exploit. That said, flexibility is important too - knowing when you use it.

As for game, I set a rule on an iPad. No games with ads. Those seem to be the worst of them, and there are tons.

It’s indisputable that the Iranian regime is horrid to Iranians (most of them). But what the US just did is actually strenghtening the grip of the Islamic regime, they get unified against an attacker, their aging aytolah turned into a martyr and a new young one was put in place, oil fields set on fire, plenty of indiscriminate bombing on civillians and so on. This is a major fuck-up.

Fascinating links, but I could not find an example of the glyph in question? My point was that a sextant is not (and cannot be) used to measure azimuth. It primarily measures the angle between a celestial body and the horizon (i.e. altitude). It can also (theoretically, very rarely) be used to measure the horizontal angle between two or more landmarks, but that is not azimuth in the accepted sense of the word. I am happy to be corrected though; my experience of sextants may be too narrow or modern for this context.

In US highways the exit ramp off the road is usually on the right, but is some cases the exit is on the left, especially in areas where the highway is elevated or in crammed downtowns. The left lane is also usually the “passing lane” and cars drive faster than on the right, so if there is a left exit and you’re cruising on the right line, you have to know in advance to safely move over to the left

I liked how it read. Not as a perfectly thought out post but more an ongoing conversation.

These are confusing times for engineers as the automators can now automate themselves away at even greater speed. Reminding ourselves to play positive sum games seems relevant.

The cake is too small to divide with humans and AI. We all feel that. Time to make more cakes :)

> It's clearing the path for the people of that country to execute regime change for themselves.

That is fundamentally untrue. In Venezuela, regime ended up completely intact, except the change on the top. There is no "clearing the path" and there is no "regime change".

In Iran, protests stopped. The lead was replaced by more hardline lead. Nationalists now wont go against the regime, even if they dislike it.

If they loose control over country, there will be civil war and unrest, but all chances of some moderates consolidating power went down. Or, even more likely, regime wont fail and will have stronger grip over the country.

> Russia loses its drone and missile manufacturer,

This war is massive gift to Russia. The sanctions are removed, the oil prices go up. Russia wants this war to go on as long as possible, it is like a lifeline for them.

> It meant to say: long press will allow you to paint in a rectangle. So long press one corner, then press another corner.

OK, after reading this explanation I could trigger it in a pc. I'm not sure if it's useful.

> Btw, my goal was to have zero language in the app, so I wouldn't have to make any translations, and it would just work for kids of any age. Hence the somewhat weird '?' popup.

I think it's fine. [Hi from Argentina!]

Before more details, I want to say that I like the idea of the multiple shapes and combinations.

Some bug reports/ feature requests:

* In the main screen, the grey rectangle is not aligned with the other rectangles.

* The white rectangle cleans the eyes/noses/whatever/ but it does not clean the skin color.

* Also, perhaps the grey rectangle probably shoud cycle like: nothing->grey->red->dark->pink->nothing->grey->... Or skip the "nothing" color in the list, but make the white rectangle delete the color.

* When I use the grey rectangle tool over an eye or something, it may change to another eye. I prefer that they change only when I use the eye tool over and eye. I expect the grey rectangle tool only to change the color, not the shape.

* I don't like that the nose rotate when it's grey and some of the nearby squares are aso grey. It's too unpredictable. I'd prefer that using a nose on a nose will sometimes change the shape and other times rotate it, so I can click on it until I get the shape I want.

Let's all boycott Google folks, I want all of HN to band together and in solidarity just not use Google for anything...

Let's see if anyone here has the guts to even switch away from GCP, scratch that can folks even move away from Apple(Apple pays for Gemini too) and Android?

I do think OpenAI deserves the boycott but people talking about Anthropic as they were taking some kind of ethical stand when it was just ego tripping for everyone involved is insane.

Maybe.

I'd say AI makes a lot more sense at the Guardian than it does Amazon.

If AI at the Guardian gets a few facts wrong, no big deal. Most readers probably won't notice.
So better luck next time.

But if AI at Amazon gets a few facts wrong, millions of customers can be directly impacted. And this is hard not to notice.

It doesn't take much noticing before customers start going elsewhere.

And then of course he continues (although won't make for a good social media rage point so understandable you didn't provide full context):

> Well, I actually think it's a brilliant idea if it can be done in an educational way that's legal.

> no free Robux, no free prizes, just a game called the dress to impress predictor where it's not like trying to get kids money or anything like that.

Still, probably what he sees in his mind is "more money yay" as always, he is a CEO of a for-profit company, that's what they do. But still felt disingenuous not to include the full context, doesn't even make it "that much better", he still seems like a scumbag with it.

That... depends on your keyboard maybe? On Dvorak the curly brackets are harder to reach than the round brackets. The open round bracket is also hit with the ring finger instead of the little finger, which is weaker.

It's quick, catchy, and convenient to call out a few corp's which pay their workers squat while the bosses rake it in.

BUT - what about the ever-inflating costs of basic daily living - housing, food, medical care, transportation, and education - for the 99% of Americans who aren't too rich to care? Does that not count as "affordability crisis", because denouncing it risks being non-performative activism? After all, if we somehow rolled back that inflation, it would hit the pocketbooks of the 1% pretty hard...

>And nearly half of the US supports this.

This does not accurately describe the picture.

When the US went to Iraq the approval rating was in the 90s(correction I mixed up Iraq and Afghanistan, Iraq was 70-80s) because the US had been attacked, and Bush took the time to sell the war to the Americans (with lies) by the time all the disasters kept coming in, support dropped to the 40s.

This war started in the 40s approval rating. If bodies start coming home in mass, I don't know how things will turn out for Trump and his party but its already looking like a disaster for them and it hasn't even hit the really ugly part yet.

And well, and he wants it done for a "educational" purpose without Robux (which I assume is the in-game currency), slightly missing context from your TLDR there.

But as mentioned in https://news.ycombinator.com/item?id=47334696, for sure he's still out after dat monez, he's the CEO after all.

> fires a $1m missile

But are they really 1 million dollars? I've always had the feeling that the cost of military equipment in peacetime has an extreme inflated price because it's a tax payer black hole with so much bureaucracy, middlemen and some level of corruption that you can charge almost any price you want.
In a war economy where the goal is to make as many missiles as possible, would governments really pay 1M a piece?
by noduerme | 2026-03-11 12:29:22+00:00
It's a real problem that Trump himself and his movement seem incapable of articulating a positive vision of America. It's an equally serious problem that the opposition are equally negative about the country, its history, its promise and potential. Both factions seem to be serving as negative emissaries. No one has less vision of America than MAGA; and no one hates it more than the Democratic Socialists. This isn't really an accident, in my opinion. And it's not just due to "hyperfinancialization" or growing economic inequality or racial disparities - all of those are issues.

Call me paranoid, but I think it's due to one of our greatest strengths being hijacked. Our free speech laws and the openness of our society, the total non-filtering of information - which I support - have created a fertile ground for sophisticated propaganda from China and Russia, Iran and Qatar, to overwhelm the brains of a lot of people on both sides of our political divide through massive social media psyops that have gone on for a decade.

It's reached the point that very few people in America can state why America is a good thing, even for its own citizens, let alone for the rest of the world.

But not very long ago, this was not the case. And there are excellent arguments to be made for why America should remain the keystone of the global order: It's inclusive, it's progressive, its system has been a miraculous engine of economic growth for everyone in its orbit. But the easiest and most banal reason, one which no one says out loud is: If not America, which country would you rather have exercising power to create some kind of international order? The people who think everything America does is automatically evil haven't really made much study of what life is like under the realistic alternatives to that question.

Native builds are always a safer/more reliable path to take than cross-compiling, which usually requires solid native builds to be operational before the cross environment can be reliably trusted.

Its a bootstrapping chain of priority. Once a native build regime is set in stone, cross compiling harnesses can be built to exploit the beachhead.

I have saved many a failing projects budget and deadline by just putting the compiler onboard and obviating the hacky scaffolding usually required for reliable cross compiling at the beginning stages of a new architecture project, and I suspect this is the case here too ..

I almost posted this exact comment. You're not alone in thinking HN has changed for the worse in recent years.

I get that it's just a reflection of cultural change and (over)reactions to anything adding friction. But for a forum dedicated to the "hacker" lifestyle, it's disappointing to see so much gatekeeping and FUD. I really wish this audience could start swinging back towards a response style that contains nuance and recognizes nuance.

I find myself opening this site less and less each week.

Surgical masks don't stop you from getting Covid. That was never what they were for: they were to reduce the viral load you exposed others to, between when you got infected and when you noticed that you were infected. See https://en.wikipedia.org/wiki/Surgical_mask#Function.

Some cloth masks can (when dry) also trap small particulates through electrostatic interactions, although they are less effective as a mechanical filter than surgical masks; and many washing methods destroy this effect.

I think the biggest problem that you hint as is that "metaverse" is an ill-defined term. When they rebranded, and given that I had been working in the 3d industry for _many_ years, I couldn’t define what the metaverse was.

To some extent I still cant. The real indicator is when the crypto bros started peddling it, then we all knew it was shite.
